The guidance in full
Reproduced from the primary documents so you can check the tool against its sources rather than trusting it.
The screening tool, as published (LMTS Appendix 1)
Older people’s trauma screening tool for TUs, MTCs, and Local Emergency Hospitals.
Inclusion criteria: “All patients ≥ 65 who self-present or arrive by ambulance with an obvious injury, mechanism of injury, or who have fallen < 2m.”
Red criteria → immediate EM consultant or registrar (ST4+ or equivalent) review, and a trauma call (document if the decision is not to activate)
Anatomy of injury: significant injury to ≥ 2 body regions; suspected pelvic injury; suspected head or spinal injury; suspected chest injury.
Physiology: systolic BP < 110 mmHg; heart rate > 90 bpm; GCS < 15 (even if baseline); lactate > 2 or base excess < −2.
Other: patient on anticoagulant medication or has a bleeding disorder; severe pain; acutely short of breath; uncontrollable major haemorrhage.
Amber criteria → EM consultant or registrar (ST4+ or equivalent) review within 15 minutes; repeat screen post examination / imaging
History of unconsciousness; significant medical history, co-morbidities; inappropriate or inadequate history; inappropriate awareness of symptoms / injury.
And the rule that catches the late presentation
“In the absence of mechanism – but identification of injury on any imaging then re-screen patient.”
The stated purpose of the trauma call, and of the patient’s clinical priority, is “adequate examination, early and adequate imaging and reporting, and early identification of all injuries”.
The tool is “adapted from HECTOR elderly trauma triage criteria and pre-hospital tools (by D Peel, A Osmond, H Tucker 2018)”. The red criteria “are independently and significantly associated with the identification of trauma in a retrospective multivariate analysis”.
Why the system under-calls it — the TARN cascade
TARN’s 2017 report reviewed 8,176 patients aged 60 and over with an Injury Severity Score greater than 15, admitted during 2014. Its central finding: “an older person suffering a fall from standing height is now the commonest type of major trauma in the national database”, and this age group “now accounts for more than 50% of the severely injured patients registered in the Trauma Audit and Research Network database”.
The report describes a cascade rather than a single failure:
“Shortcomings in the early identification of major trauma in older people leads to a low rate of positive prehospital triage with low rates of bypass to a Major Trauma Centre (MTC); low levels of pre-alert; low levels of trauma team activation and initial management by relatively junior doctors. This lower level of early activation of the trauma care system seems to lead to delays in both investigation and management.”
On seniority, the numbers are stark. The proportion of older patients initially treated by a consultant “was near to 100% if they were positive on the prehospital trauma triage tool, whatever the time of injury”. Where pre-hospital triage was negative or not done, “approximately 40% of these patients saw a consultant if they were admitted during the day, and this was further reduced to about 30% during the night.”
And the honest statement of the problem — the reason a screening tool has to be this wide:
“There is therefore a ‘needle in a haystack’ problem for the trauma system… Given the prevalence of low falls in older people, it would not be possible to activate the major trauma protocol for all of these incidents. However, current trauma triage protocols (which were primarily designed for much younger patient populations) are not working well for older people and do not reliably distinguish older patients with low falls who have sustained serious injuries from those who have not.”
One further group is easy to forget: 3.2% of older major trauma patients were “either admitted directly to a medical ward (1.7%) or sustain their injuries by falling while in hospital (1.3%)”. TARN notes these patients “may eventually be found to have a significant head or chest injury that was not immediately apparent on initial assessment”.
TARN used age 60 as its cut-off because “in the trauma data there seems to be a change in the age / outcome relationship at about 60 years old”. The LMTS guideline uses 65. Neither number is a biological threshold.
Physiology — why the numbers look reassuring and are not
From the LMTS key principles: “Ageing, comorbid disease, medications and frailty may all affect the expected physiological presentation of major trauma in older people.” And: “Older trauma patients may not present with an obviously significant mechanism.”
The pelvic injury section states the mechanism plainly: “Hypovolaemic shock may be difficult to detect in older people due to pre-existing hypertension, altered cardiovascular reserve or beta-blocker therapy. Early assessment of lactate or base deficit (excess) and haemoglobin on arrival to the ED may help to detect haemodynamic compromise following pelvic trauma, irrespective of mechanism of injury.”
This is why the screening tool’s thresholds sit where they do. A systolic of 115 in a patient whose usual pressure is 170 is not a normal blood pressure, and a rate-controlled heart cannot mount a tachycardia. The tool responds by moving the trigger points — systolic < 110 and heart rate > 90 — and by adding a metabolic criterion, lactate > 2 or base excess < −2, that does not depend on the patient’s ability to compensate.
GCS < 15 “even if baseline” deserves separate attention. The parenthesis exists because “this is their normal” is the most common way a reduced conscious level gets written off in this group.
Neurotrauma — the low threshold, and the collapse that is a subdural
“There should be a low threshold for initiating a ‘trauma call’ and obtaining a head CT scan in the older patient, especially in the following presentations:
- When known or suspected to have sustained head injury.
- Following a low level fall (e.g. from standing or sitting).
- When taking prescribed anticoagulant medication.
- When there is no clear medical cause of fall or unclear reason for ED attendance.”
The reason for that last one is given explicitly: “These suggestions are in light of the perceived number of older patients who present as a ‘collapse’ and who, after admission, are found to have an acute or chronic subdural haematoma.”
Scan the neck with the head
“Where an older patient has clear external signs of head injury or has neck pain or has endured a fall, and if a decision has been made to CT the patient’s head, this should include the cervical spine.”
Blood on the CT re-opens the whole assessment
“The presence of blood on CT head should trigger review of other potential traumatic injuries by experienced trauma clinician or a delayed trauma call.” Any acute intracranial blood “should result in a discussion with the MTC team… and such referrals should be logged and documented by the referrer and the advisor.”
The repeat scan
“Anticoagulated patients with a head injury and normal initial CT head may require a repeat scan. There is no clear evidence for optimum timeframe for this repeat CT, thus local policy or a senior clinician should decide based on mechanism, frailty, social support and degree of anticoagulation.” The uncertainty is in the source — it is not this tool hedging.
Three pathways for isolated TBI
1. Unsurvivable — discussion with the neurosurgeon by phone and/or remote medicine; the patient can stay at the TU. 2. No immediate neurosurgical input — stay at the TU, repeat scan at 48 hours or as the neurosurgical team specifies; if GCS falls or a new neurological sign appears, rapid discussion with a view to critical transfer to the MTC ED, “not dependent on bed status of MTC”. 3. Neurosurgical intervention required — immediate transfer to the MTC ED with a time-critical head injury pre-alert.
Chest wall injury — the numbers that justify the CT
“Chest wall injuries are common in older patients and are associated with significantly higher morbidity and mortality than younger patients, whether they occur as part of isolated or multi-system trauma.”
“Ten per cent of older major trauma patients have rib fractures and up to 50% of fractures in this group are undetected by plain X-ray. A meta-analysis of 50,000 patients, including 15,000 people aged over 65 years indicated an odds ratio for mortality of 1.98 for those over 65 years with any rib fractures, and for all ages an odds ratio for mortality of 2.02 with 3+ rib fractures. Associated pulmonary contusion or pre-existing chronic lung disease are also significant prognostic findings.”
Hence: “Contrast CT scan is the investigation of choice to define intrathoracic and chest wall injuries early in the older trauma pathway,” because of “the poor recognition of fractures and lung contusions with X-ray and the prognostic influence of an accurate diagnosis”.
“The type and number of affected ribs is an important consideration. Vertebrosternal ribs (ribs 1-7) have greater physiological significance than vertebrocostal ribs (ribs 8-10).”
Analgesia cautions specific to older patients
- “NSAIDs should be used with extreme caution due to renal, cardiac and GI risks. They should be used for shortest duration course possible e.g. 3-5 days.”
- “Opioids should be used in lower doses. If a strong opioid is required, clinicians should have a low threshold for choosing oxycodone due to its favourable side effect profile.”
The guideline names the bind directly: “a higher proportion of older trauma patients would benefit from regional anaesthetic techniques but are more likely to have contraindications (e.g. anticoagulants) to deep regional techniques e.g. epidural or paravertebral block insertion.”
Assessment should cover pain at rest (static) and pain on deep breathing and coughing (dynamic). Incentive spirometry or vital capacity can identify patients at risk of deterioration. Severe chest wall injuries, radiological or clinical flail chest, injuries causing respiratory compromise, or pain that cannot be controlled “should be discussed early with the MTC trauma or thoracic surgeon”.
Cervical spine — when the collar is the injury
“Evidence for the benefits of pre-hospital cervical spine immobilisation in reducing secondary neurological injury in unstable injuries is poor. There are however well documented cases of worsened neurological injury in patients with poorly fitting collars or hyperextended positions. Presence of severe degenerative disease in older patients (including ankylosing spondylitis) puts them at particular risk and consideration should be given for pragmatic alternatives to hard collar stabilisation including self-extrication, careful handling and movement mitigation, with transport in a position of comfort using soft padding and tape if necessary.”
“Older patients are at high risk of pressure ulcers, pneumonia and respiratory failure, dysphagia, delirium and raised intracranial pressure with prolonged cervical immobilisation. Many find hard collars and lying flat uncomfortable, painful and frightening.”
The clock the guideline sets: “Assessment, imaging and imaging reporting should be completed within two hours of arrival/decision to immobilize. If continued immobilization is required rigid extrication collars should be switched to soft padded collars (such as Miami-J) at the earliest opportunity and movement restrictions should be clearly documented within one hour of imaging reporting.”
“Interpretation of cervical imaging in the presence of severe degenerative disease can be challenging. Escalation for specialist reporting should be included in local trauma protocols to prevent delays in decisions regarding immobilisation.”
For patients who cannot tolerate immobilisation — “particularly those with dementia, delirium or coexistent traumatic brain injury” — a senior clinician should weigh comfort optimisation, delirium reduction strategies, the risk/benefit of immobilisation itself including the risk of pneumonia and aspiration, and the risk/benefit of sedation. On that last point the guideline is unambiguous: “Sedation is not without risk and should not be considered standard practice in these situations.”
Cord injury from a low-energy mechanism
“Although uncommon, there is increased risk of spinal cord injury (SCI) in older people due to degenerative disease and canal stenosis, with incomplete cord syndromes possible from relative low energy mechanisms. Network spinal injury pathways should include management of cord injury in older people including the incomplete cord syndromes.”
And a time standard that is easy to miss: “Older patients with SCI should be referred to spinal cord injury centres within four hours of identification of the injury as recommended in national guidance from the Multidisciplinary Association of Spinal Cord Injury Professionals (MASCIP).”
On the incidental finding problem: “Fragility fractures in the thoracic region are relatively common in older patients and are often incidental findings on imaging. Physical examination and imaging beyond plain films (CT or MRI) should aid in the determination of acuity in these injuries.” The four network pathways LMTS names are stable fractures for analgesia; unstable fractures for brace therapy; unstable fracture requiring surgical intervention; and highly unstable fracture for urgent intervention.
The imaging criteria themselves are in NICE NG232 and are worked through in the CT head & C-spine module.
Pelvis — and the pubic ramus fracture that is not simple
“All older patients who present to the ED with a suspected pelvic fracture should be assessed by the trauma team.” And: “If a pelvic fracture is identified on X-ray after a low energy fall, then activation of the trauma team for a full trauma assessment is recommended.”
“A pelvic or sacral insufficiency fracture which commonly accompanies a simple pubic ramus fracture will at least cause back pain, and may render the pelvis unstable. Urgent CT should be requested in symptomatic older patient (pain, reduced mobility).”
“Code red or major haemorrhage protocols should be activated as for any adult patient with known or suspected haemorrhage. Vasoconstrictors should be avoided. Pelvic binders should be applied as part of haemorrhage control. However, caution must be exercised for long term application (more than 12 hours) in older patients with poor skin integrity.”
“All older patients with acetabular fractures should be referred to the MTC pelvic surgery service for expert advice and possible transfer. This referral should occur within 12 hours of radiological (CT) confirmation of the injury,” with IEP CT images and a documented lower limb neurological assessment.
Whole-body CT
“Use whole-body CT (consisting of a vertex-to-toes scanogram followed by CT from vertex to mid-thigh) in adults (16 or over) with blunt major trauma and suspected multiple injuries. Patients should not be repositioned during whole-body CT.” This identical wording appears in both NICE guidelines — NG37 recommendation 1.2.8 and NG39 recommendation 1.5.34.
Anticoagulation — the one-hour clock
“Each MTC and TU should have a policy for the reversal of warfarin and other anticoagulants following major trauma. PCC should be immediately available for every major trauma patient with life threatening bleeding. Anticoagulant reversal should be administered on arrival in older trauma patients (no longer than within one hour of decision to reverse).”
From the key principles: “Consider timely anticoagulant reversal during the initial assessment of all older trauma patients.”
Warfarin with intracranial bleeding
“Patients on warfarin with intracranial bleeding should receive prothrombin complex concentrate (PCC) in addition to vitamin K, unless the bleed is extremely small and risk of procoagulation is considerable. In those patients known or suspected to be on anticoagulants, an INR test should be completed as soon as possible. (Point of care testing may be required.)”
Factor Xa inhibitors in trauma
The LMTS consensus for a known or suspected life-threatening haemorrhage from trauma on rivaroxaban, apixaban or edoxaban: “Administer 25-50u/kg four-factor prothrombin complex concentrate (e.g. Octaplex ® or Beriplex®) and 5mg intravenous vitamin K as soon as possible after arrival at the ED. Vitamin K will not reverse the anticoagulant effect of a DOAC but may help correct any coagulopathy resulting from co existing vitamin K deficiency.” Ensure a tranexamic acid bolus has been given, and consult the on-call haematologist emergently if bleeding continues.
Note that this document dates from April 2021 and states that for factor Xa inhibitors “reversal agents are currently unavailable”. NICE TA697 recommends andexanet alfa — but only for life-threatening or uncontrolled bleeding in the gastrointestinal tract, which is not this patient. For traumatic haemorrhage the PCC route above remains the UK consensus.
Dabigatran
“Administer Idarucizumab 5g intravenously as soon as possible after arrival at the ED. If bleeding reoccurs and clotting times are prolonged then a second dose of Idarucizumab 5g may be required.”
Antiplatelets and restarting
For TBI, LMTS says “administration of platelets should be considered if the patient is taking any antiplatelet therapy” — a position that sits uneasily with the PATCH trial, which found higher odds of death or dependence with platelet transfusion in antiplatelet-associated intracerebral haemorrhage. PATCH studied spontaneous ICH rather than traumatic ICH, so it does not settle the traumatic case, but the tension is real and worth naming rather than resolving silently. See the reversal module.
On restarting: “In the absence of robust evidence in this field, individualised treatment plans balancing risk of thrombosis and bleeding made in collaboration with geriatric and neurosurgical teams are required. In minor TBI, early initiation of LMWH may be appropriate after admission. Timing of restarting anticoagulation should be clearly documented.”
What RCEM asks of departments
The document separates six Standards — phrased as must — from ten Recommendations, phrased as should. The standards are the harder edge, and two of them apply to every injured older patient:
- “Hospitals must provide an Acute Frailty service for at least 70 hours a week, with the aim to complete a clinical frailty assessment within 30 minutes of a patient’s arrival in the Emergency Department or SDEC unit.”
- “Pain scores must be obtained in all older aged patients at triage.”
- “The ED staff must support patients to remain as independent as possible whilst they remain in the ED.”
- “Each Emergency Department must have a Geriatric Emergency Medicine/Frailty lead.”
- “All staff working in the Emergency Department must complete dementia and delirium training.”
- “All EDs must have ready access to time critical medication used commonly by older people, such as Parkinson’s Disease medication, insulin and anti-epileptic medicines.”
The introduction sets the frame the rest of this module rests on: “All older people have the right to a health and social care assessment and should have access to treatments and care based on need, without an age-defined restriction to services. Health services should not be ‘ageist’.”
The recommendations then open with this one:
“All EM staff should have protocols for the management of ‘silver trauma.’”
Its background section sets the clinical frame: “‘Silver trauma’ assessment should take into account the differing injury patterns and physiological responses (co-existent morbidities and polypharmacy) of the older person. Lower thresholds for CT scanning and high suspicion for occult injuries are central to safe and effective care; traumatic brain injuries and chest wall injuries are the most common cause of death. Departments must have clear protocols for common clinical scenarios eg. anticoagulation reversal, as well as admission pathways whether isolated injuries (eg. pubic rami fracture) or multi-system involvement.”
On frailty scoring
RCEM recommends that “ED staff should undertake Clinical Frailty Scale (CFS) scoring if it will make a meaningful difference to their ED management” — and repeats the qualifier in the background text, which is unusual enough to be deliberate. The CFS “is a tool for those aged 65 years and older. Many Emergency Departments use 75 years and older as the recommended age for frailty scoring.” It describes the patient’s baseline two weeks before presentation, not how they look now.
LMTS makes the same point from the other direction: “Early frailty identification is to augment decision making and expedite access to specialist geriatrician services, not to deny access to care.”
This tool deliberately does not reproduce or calculate the Clinical Frailty Scale. It is a licensed instrument with its own descriptors and training requirements — use your department’s licensed copy.
Pain
“Pain is often under recognised in the Emergency Department especially in older aged patients and those with a cognitive impairment such as dementia. If the patient is unable to communicate verbally, non-verbal cues should be looked for such as agitated behaviour and facial grimacing. The Abbey Pain Tool may be useful.” Ask the family or carer whether they think the patient is in pain, and how the team would recognise it.
Frailty syndromes, and the hip fracture bundle
“ED staff should be adept at recognising common frailty syndromes including, Frailty Delirium, Falls, Polypharmacy, suspected fracture neck of femur (#NoF) and end of life (EoL) care.”
“It should be recognised that delirium is a medical emergency with associated high rates of mortality and morbidity. Following identification of delirium, pathway should be initiated to help identify precipitants and provide appropriate acute management eg. TIME bundle.” The 4AT is the recommended assessment tool.
“Patients who have a clinical suspicion or confirmation of a hip fracture should have the Big Six interventions/treatments before leaving the ED (pain relief, delirium screen, NEWS2 score, bloods & ECG, pressure area assessment and IV fluids started).”
“Consider referral to community based teams if the patient has had two or more falls in the last 12 months or has problems with walking or balance.”
On medication: “For older aged patients a medication review is suggested, to include medication reconciliation, identification of polypharmacy, anticholinergic burden, drug interactions and side effects, compliance with medication and understanding of use. For older aged patients the STOPP/START tool is an example of a medication review tool. Any medication changes must be conveyed to the patients General Practice team and in writing to the patient.”
On escalation: “EDs should have ready access to Treatment Escalation Plans (TEPs) and Recommended Summary Plan for Emergency care and Treatment ReSPECT information. If there is an acute necessity for a ReSPECT conversation, i.e. it is thought the patient will die in the Emergency Department, effort should be made to include the patient and their nominated family members in the conversation.”
And on discharge: “An accurate and meaningful discharge letter and telephone handover is particularly important for patients who are unable to retain the information themselves or communicate it to care providers, such as those living with dementia. It is also useful to document the time last medications were given and any medication changes.”
The principle underneath all of it
From the LMTS executive summary: “All older major trauma patients should receive the same standards of care as for any other major trauma patient.” And on admission: “Older trauma patients should receive the same trauma care following admission as that given to younger adults (those under 65 years of age).”
The guideline also argues against the existence of documents like itself: “At a network, MTC and TU level there should not be a requirement to develop multiple clinical guidelines specifically for older major trauma. Given the identified and continued rise in the proportion of older patients within the trauma system, it is more appropriate that all local and network guidelines relating to trauma should include elements which are specific to older and/or frail patients.”
TARN’s version of the same conclusion: “There are two distinct types of major trauma - high energy transfer trauma in younger patients and low energy transfer trauma in older patients. Each of these types account for about half of major trauma cases.”
The point of a silver trauma module is not that these patients need different care. It is that they need the same care, and the system is much less likely to give it to them.
Why the physiology and the mechanism mislead the system, and the mistakes that follow, are under Teaching. The studies behind the numbers are under Evidence. What this tool does not do, and its sources in full, are under About.

The decision tool tells you what to do. This chapter is about why — why an older person’s physiology hides a serious injury, why the word “mechanical” closes the assessment before it starts, and why a trauma system built around young people in fast cars keeps missing the patient who is now its commonest customer. It is meant to be read before the shift, not during it.
An 84-year-old woman is brought in after “a mechanical fall” at home. She takes apixaban for atrial fibrillation and bisoprolol. GCS is 14 — “that’s her baseline, she has dementia,” the crew say. Heart rate 84, blood pressure 138/82. She is triaged to majors, not resus, and booked in for a hip X-ray because she has left hip pain. The X-ray shows a pubic ramus fracture, so she is referred to the orthopaedic team as “a rami fracture for the ward.” No head CT is requested. Her usual blood pressure, had anyone looked, is 176/94.
By the end of this chapter you should be able to name at least six things in that paragraph that are wrong, or reassuring for the wrong reason. They are listed at the bottom.
Why we do what we do, in one table
Every part of the screening tool, and the reason it is there.
| What we do | Why | Basis |
|---|---|---|
| Screen everyone 65+ with an injury, a mechanism, or a fall under 2 m | The commonest kind of major trauma in the UK is now an older person who fell from standing — but that is a needle in a haystack, so the net has to be deliberately wide. | LMTS App. 1 Kehoe 2015 |
| Trigger on systolic <110 and heart rate >90 | Older mortality starts rising at a heart rate of 90 and a systolic of 110 — thresholds a younger patient would sail through. Reserve, hypertension and rate control hide shock. | LMTS App. 1 Heffernan 2010 |
| Add a metabolic trigger (lactate >2 or base excess <−2) | A metabolic marker does not depend on the patient’s ability to compensate, so it catches the shock that the blood pressure is hiding. | LMTS p.15 |
| Count GCS <15 “even if baseline” | “This is just her normal” is the commonest way a reduced conscious level — sometimes a subdural — gets written off. | LMTS App. 1 |
| Low threshold for CT head after any low fall, especially on an anticoagulant | Older people present as “a collapse” and are then found to have an acute or chronic subdural. Anticoagulation widens the bleed. | LMTS p.11 NG232 |
| Contrast CT chest, not a plain film | Up to half of rib fractures in this group are invisible on X-ray, and chest wall injury is one of the two commonest causes of death. | LMTS pp.17–18 |
| Reverse anticoagulation within an hour of the decision | The bleed the reversal is racing is often intracranial and expanding; delay is measured in outcome, not convenience. | LMTS p.19 NG39 1.5.6–1.5.12 |
| Treat a pubic ramus fracture after a low fall as a trauma call, not a ward referral | A companion sacral or pelvic insufficiency fracture can make the ring unstable and can bleed; the “simple” label is the trap. | LMTS p.15 |
| Re-screen after imaging, and do the falls assessment even when nothing is found | Injury in older people declares itself late, and a negative trauma screen is the start of the falls work-up, not the end of the encounter. | LMTS App. 1, p.20 |
The reframing: major trauma changed and the system did not
Why “silver trauma” is a system problem before it is a clinical one.
For most of the history of trauma care, a major trauma patient was a young man in a fast vehicle. Trauma services — the triage tools, the trauma call, the receiving teams, the whole reflex — were built around that patient. Then the demographics moved out from under them.
TARN’s 2017 report put it plainly: “an older person suffering a fall from standing height is now the commonest type of major trauma in the national database.” TARN 2017 This is not a minor sub-population. It is the main event, wearing a disguise the system was not trained to see through.
The disguise matters because the trauma system runs on pattern recognition, and the pattern is wrong. TARN describes a cascade: low rates of correct pre-hospital triage lead to low rates of pre-alert, low rates of trauma-team activation, and initial care by relatively junior clinicians — which in turn delays investigation and treatment. The seniority gap is stark: an older patient who screened positive pre-hospital was seen by a consultant nearly 100% of the time, but where triage was negative or not done, only about 40% saw a consultant by day and 30% by night. TARN 2017
The point of a silver trauma protocol is not that these patients need different care. It is that they need the same care, and the system is far less likely to give it to them unless something forces the question. The screening tool is that forcing function.
This is also why the honest position, stated by LMTS itself, is that documents like this one should eventually not need to exist: “it is more appropriate that all local and network guidelines relating to trauma should include elements which are specific to older and/or frail patients.” LMTS p.6 Until they do, you need the tool.
The physiology that lies
Why a normal set of observations is the most dangerous thing on the chart.
A young person in haemorrhagic shock mounts a tachycardia and, late, drops their pressure. That physiological alarm is what the standard trauma thresholds are tuned to. The older patient rings it quietly, or not at all, for three reasons that stack:
- Reduced reserve. A stiff heart and stiff vessels cannot increase output the way a young circulation can, so compensation fails earlier and more abruptly — the patient looks fine, then collapses.
- Baseline hypertension. A systolic of 130 looks reassuring until you know their usual pressure is 180. A “normal” number can represent a substantial, occult fall in perfusion. Teaching
- Rate control. A beta-blocker or a rate-limiting calcium-channel blocker means the heart cannot mount a tachycardia. The single most reliable early sign of bleeding is switched off pharmacologically. LMTS p.15
The evidence for exactly where to move the alarm is Heffernan’s 2010 study of over 4,000 blunt trauma patients. In the over-65s, mortality began to climb once the heart rate exceeded 90 — an association not seen in the young until 130 — and once the systolic dropped below 110, versus 95 in the young. Heffernan 2010 Those two numbers are the red physiology criteria in the screening tool, and now you know they are not arbitrary.
Because you cannot trust the pressure or the pulse, the tool adds a marker that does not depend on the patient compensating at all: lactate >2 or base excess <−2. LMTS is explicit about why — “early assessment of lactate or base deficit… may help to detect haemodynamic compromise following pelvic trauma, irrespective of mechanism of injury.” LMTS p.15 A raised lactate in a normotensive older patient is occult shock until proven otherwise; it is not a lab artefact to be repeated and forgotten.
In an older trauma patient, treat normal observations as an absence of evidence, not evidence of absence. Get a venous gas early. The number that catches the bleed is the lactate, not the blood pressure.
The word “mechanical”, and the mechanism that talks you out of looking
How a low-energy story becomes a low-effort assessment.
“Mechanical fall” is one of the most quietly dangerous phrases in the emergency department. It does two things at once: it implies the cause is understood (a trip, not a faint or an arrhythmia) and it implies the consequences are trivial (low energy, so no real injury). Both implications are frequently wrong, and together they close the assessment before it has started.
Take the cause first. LMTS lists “no clear medical cause of fall, or unclear reason for ED attendance” as a reason to lower the threshold for a head CT — precisely because of “the perceived number of older patients who present as a ‘collapse’ and who, after admission, are found to have an acute or chronic subdural haematoma.” LMTS p.11 A syncopal fall is a different, and more sinister, event than a trip, and “mechanical” often means nobody has looked for the syncope.
Now the consequences. Low energy does not mean low injury in a body with osteoporotic bone and a stenotic spinal canal. LMTS makes the point about the cord directly: there is increased risk of spinal cord injury in older people “with incomplete cord syndromes possible from relative low energy mechanisms.” LMTS p.14 A central cord syndrome — arms weaker than legs after a fall with neck extension — is the classic example Teaching, and the low-energy story is exactly what talks you out of examining for it. If a cord injury is found, LMTS sets a hard clock: referral to a spinal cord injury centre within four hours, per MASCIP national guidance. LMTS p.14
The systematic-review evidence backs the instinct that the front door is where this fails. Alshibani’s 2021 review of 23 studies found current triage guidelines have “poor sensitivity to identify major trauma” in older adults; modified tools improve sensitivity but lose specificity. Alshibani 2021 There is no free lunch — a net wide enough to catch the injured older patient will also catch many who are not injured. The screening tool accepts that trade deliberately, which is why it feels over-inclusive. It is supposed to.
Replace “mechanical fall” in your own head with two open questions: why did they fall, and what did they break that nobody has looked for yet? The screening tool is a way of being forced to ask both.
The brain: the collapse that is a subdural
Why the CT threshold is lower, and why the first scan is not the last word.
Traumatic brain injury is, with chest wall injury, one of the two commonest causes of death in older trauma. RCEM 2025 The brain in an older skull is unusually vulnerable to a low-energy blow: cerebral atrophy stretches the bridging veins, so a minor deceleration can tear one, and the extra space lets a subdural expand for a long time before it causes signs. Anticoagulation and antiplatelet therapy — carried by a large fraction of this population — widen every one of those bleeds.
So LMTS names four presentations that should lower the threshold for both a trauma call and a head CT: a known or suspected head injury; any low-level fall from standing or sitting; taking prescribed anticoagulant medication; and no clear medical cause for the fall or unclear reason for attendance. LMTS p.11 The NICE NG232 rules themselves — including that an anticoagulant, or an antiplatelet other than aspirin monotherapy, is on its own a reason to consider a CT head within 8 hours — are worked through in the CT head & C-spine module.
Two points about the scan are easy to get wrong. First, scan the neck with the head. Where an older patient has external signs of head injury, or neck pain, or has had a fall, and a decision is made to CT the head, “this should include the cervical spine.” LMTS p.11 Second, a normal first scan on an anticoagulant is not reassurance. LMTS: such patients “may require a repeat scan,” and is honest that “there is no clear evidence for optimum timeframe” — the decision is a senior one, made on mechanism, frailty, social support and degree of anticoagulation, and documented. LMTS p.11 The uncertainty is in the guideline, not in your judgement failing.
On tranexamic acid in head injury, be precise. CRASH-3 did not show a mortality benefit overall (within 3 hours, head-injury death 18.5% vs 19.8%, a confidence interval crossing 1). The benefit was confined to mild-to-moderate injury (RR 0.78, 95% CI 0.64–0.95), with none in severe injury. CRASH-3 TXA is safe and reasonable early in the injured older patient, but it is not a treatment for the established severe intracranial bleed, and it is never a substitute for reversing their anticoagulant.
The chest wall: the injury the plain film hides
Why the older patient with rib pain gets a CT, and why the pain score is a treatment.
Rib fractures are dangerous out of all proportion to how minor they sound, and in older people they are both commoner and harder to see. LMTS: chest wall injuries in older patients “are associated with significantly higher morbidity and mortality than younger patients,” ten per cent of older major trauma patients have rib fractures, and “up to 50% of fractures in this group are undetected by plain X-ray.” LMTS pp.17–18
That combination — high mortality, poor plain-film detection, and prognosis that turns on an accurate count — is why the investigation of choice is a contrast CT of the chest, not a chest X-ray. LMTS adds an anatomical point worth carrying: the upper ribs (1–7) have greater physiological significance than the lower ones (8–10), and associated pulmonary contusion or pre-existing lung disease are themselves prognostic. LMTS p.18
The other half of chest wall care is analgesia, and here the pain score is not paperwork — it is the intervention that prevents the death. The chain is mechanical: pain stops the patient breathing deeply and coughing, secretions pool, and pneumonia follows. So assess pain at rest and on deep breathing and coughing — the dynamic score predicts who will deteriorate — and treat it. But the older patient is caught between the drugs: NSAIDs “with extreme caution” for renal, cardiac and GI risk and for the shortest course; opioids at lower doses with a low threshold for oxycodone; and regional techniques, which would help most, often blocked by the very anticoagulants this population takes. LMTS pp.17–18 Flail chest, respiratory compromise or uncontrollable pain warrant an early conversation with the MTC thoracic or trauma surgeon.
The anticoagulant: a one-hour clock
Why reversal is a resus-room act, and where the sources genuinely disagree.
A large share of injured older people are anticoagulated, and the drug converts a survivable bleed into a fatal one by letting it keep bleeding. LMTS treats this as a time-critical intervention, not a ward job: “Anticoagulant reversal should be administered on arrival in older trauma patients (no longer than within one hour of decision to reverse),” and PCC “should be immediately available for every major trauma patient with life threatening bleeding.” LMTS p.19 This aligns with NICE NG39: rapidly reverse anticoagulation in major trauma with haemorrhage, use PCC immediately for a vitamin K antagonist, and do not reverse in the patient without active or suspected bleeding. NG39 1.5.6–1.5.12
The agent depends on the drug, and the full dosing lives in the reversal module. In outline: warfarin with intracranial bleeding gets PCC plus IV vitamin K; a factor Xa inhibitor (apixaban, rivaroxaban, edoxaban) with life-threatening traumatic haemorrhage gets, on the LMTS consensus, 25–50 U/kg four-factor PCC plus 5 mg IV vitamin K, with TXA given — noting that vitamin K does not reverse a DOAC, it addresses coexisting deficiency; dabigatran gets idarucizumab 5 g. LMTS p.19 Andexanet alfa is not the trauma answer: NICE TA697 recommends it only for life-threatening bleeding in the gastrointestinal tract. TA697
The genuine conflict is over platelets for the antiplatelet patient with a head bleed. LMTS says platelet transfusion “should be considered if the patient is taking any antiplatelet therapy” in TBI. But the PATCH trial found platelet transfusion made outcomes worse in antiplatelet-associated intracerebral haemorrhage — death or dependence at three months had an adjusted common odds ratio of 2.05 (95% CI 1.18–3.56). PATCH The escape hatch is real but narrow: PATCH studied spontaneous intracerebral haemorrhage, not traumatic, so it does not settle the traumatic case. What it does settle is that “give platelets” is not a safe reflex. Make the decision with haematology and neurosurgery, and record the reasoning rather than resolving the tension silently.
Frailty, and the same standard of care
What frailty scoring is for, what the Big Six catch, and the principle underneath all of it.
Frailty is a measure of physiological reserve, and it predicts trauma outcomes better than age does — which is why age is a screening cut-off, not a biological threshold. In a prospective comparison of frailty scores in geriatric trauma, the Trauma-Specific Frailty Index and the Rockwood Frailty Score predicted mortality, complications and discharge destination well, and the authors proposed the TSFI as a practical universal score. Hamidi/Joseph 2019
But the purpose of scoring is easy to invert, so both national documents guard against it. LMTS: early frailty identification is “to augment decision making and expedite access to specialist geriatrician services, not to deny access to care.” LMTS p.5 RCEM asks that the Clinical Frailty Scale be scored only “if it will make a meaningful difference to their ED management,” and describes the patient’s baseline two weeks before presentation, not how they look mid-resus. RCEM 2025 This tool deliberately does not calculate the CFS: it is a licensed instrument with its own descriptors and training — use your department’s copy.
Frailty also comes with syndromes that ride alongside the injury. RCEM asks ED staff to recognise the common ones — delirium, falls, polypharmacy, suspected hip fracture, and end-of-life care — and names two hard-edged, injury-relevant standards:
- Pain scores must be obtained in all older patients at triage — stated as a standard, not a recommendation. In cognitive impairment, look for non-verbal cues and ask the family how this person shows pain; the Abbey Pain Tool may help. RCEM 2025
- Delirium is a medical emergency. Screen with the 4AT and start a pathway (e.g. TIME) to find and treat the precipitant. In an injured patient, delirium is also a reason to re-examine — it degrades the history and masks pain. RCEM 2025
And the archetypal presentation, the hip fracture, gets a bundle: the Big Six before the patient leaves the ED — pain relief, delirium screen, NEWS2, bloods and ECG, pressure-area assessment, and IV fluids started. RCEM 2025 One caution the tool carries in the same breath: an isolated fractured neck of femur is not even in the TARN major-trauma dataset, so the national picture is drawn with it excluded — and the hip fracture is exactly the single-site injury that stops people looking any further.
LMTS: “All older major trauma patients should receive the same standards of care as for any other major trauma patient.” LMTS p.4 Everything in this module is machinery for making that ordinary sentence actually happen.
Ten pitfalls
Each of these has sent an injured older patient down the wrong pathway. None requires an unusual patient — they are the default failures.
01 “Mechanical fall” as a diagnosis
- The trap
- The phrase closes both questions — why they fell and what they broke — at triage.
- Instead
- Treat it as two open questions. A fall with no clear medical cause is itself a reason to CT the head. LMTS p.11
02 Reassured by normal observations
- The trap
- HR 84, BP 138/82 reads as stable and downgrades the patient to majors.
- Instead
- Reserve, hypertension and rate control hide shock. Mortality rises from HR 90 and SBP 110 in this group; get a lactate. Heffernan 2010
03 A “normal” pressure in a hypertensive patient
- The trap
- A systolic of 130 looks fine; nobody knows their usual is 180.
- Instead
- A normal number can be a large occult fall in perfusion. Anchor to the patient’s baseline, not the reference range. Teaching
04 “GCS 14 is her baseline”
- The trap
- A reduced conscious level is attributed to dementia and not investigated.
- Instead
- The screening tool counts GCS <15 “even if baseline” for exactly this reason — it is the commonest way a subdural gets written off. LMTS App. 1
05 No head CT because “it’s just a fall”
- The trap
- Low energy plus an anticoagulant, and still no scan.
- Instead
- An anticoagulant, or an antiplatelet other than aspirin monotherapy, is on its own an NG232 reason to image. Low fall + anticoagulant is a low threshold, not a high one. NG232
06 A plain chest film for chest wall pain
- The trap
- A normal or unimpressive CXR is taken to exclude significant injury.
- Instead
- Up to half of rib fractures here are invisible on plain film; the investigation of choice is contrast CT chest. LMTS pp.17–18
07 “Isolated pubic ramus fracture, for the ward”
- The trap
- A ramus fracture after a low fall is treated as simple and referred straight to orthopaedics.
- Instead
- A pelvic fracture after a low fall is a reason to activate the trauma team; a companion insufficiency fracture can destabilise the ring and bleed. LMTS p.15
08 Vasopressors for the bleeding pelvis
- The trap
- Reaching for a vasoconstrictor to prop up the pressure in pelvic haemorrhage.
- Instead
- LMTS is explicit: activate the major haemorrhage protocol, apply a binder, and avoid vasoconstrictors. Take the binder off within 12 hours where skin integrity is poor. LMTS p.15
09 Anticoagulant reversal treated as non-urgent
- The trap
- Reversal is deferred while imaging and referrals happen.
- Instead
- LMTS sets a clock: reversal on arrival, within one hour of the decision. Send the INR immediately; PCC should be to hand. LMTS p.19
10 A negative screen ends the encounter
- The trap
- No criteria met, so the patient is discharged with no falls work-up, and never re-screened after imaging.
- Instead
- A negative screen is the start of the falls assessment, and any injury found on later imaging triggers a re-screen. LMTS App. 1, p.20
Seven red herrings
Findings that feel reassuring, or feel like a reason to act, and are neither.
A fall from standing is now the commonest mechanism of major trauma in the UK. The energy is low; the injury need not be. Kehoe 2015
In a normotensive older patient, a raised lactate is occult shock until proven otherwise — not a number to repeat and forget.
The screening tool explicitly includes self-presenters. Arriving under your own steam is not a physiological clearance.
Maybe. But the same picture is how an acute or chronic subdural presents, which is why the tool refuses to discount a low GCS as baseline.
PATCH found platelet transfusion worsened outcomes in antiplatelet-associated ICH. It studied spontaneous bleeds, so it does not settle trauma — but it kills the reflex. PATCH
CRASH-3 showed no overall benefit and none in severe injury; benefit was confined to mild-to-moderate TBI. TXA is not a treatment for the established severe bleed. CRASH-3
On an anticoagulant, a normal initial scan may need repeating — LMTS says so, and admits the timing is not evidence-based. It is a senior, documented decision. LMTS p.11
The case, revisited
The 84-year-old woman, in order:
- “Mechanical fall” assumed both a benign cause and a benign consequence. Neither was established — nobody asked why she fell.
- Normal observations misread. HR 84 on bisoprolol cannot rise; BP 138/82 against a baseline of 176/94 is a large occult drop. Both should have prompted a lactate, not reassurance.
- GCS 14 waved off as “baseline.” The tool counts GCS <15 even if baseline — on apixaban, this is a head CT until proven otherwise.
- No head CT. A low fall on a DOAC is one of the four LMTS triggers, and an anticoagulant is an NG232 indication in its own right.
- Triaged to majors, not resus, and clerked juniorly. This is the TARN cascade in miniature — the under-triage that leads to delayed care.
- “Rami fracture for the ward.” A pelvic fracture after a low fall is a trauma-team activation, and a ramus fracture may hide a bleeding insufficiency fracture — not a simple ward referral.
- Reversal never considered. If she is bleeding, apixaban should be reversed within an hour of the decision — a clock nobody started.
Every one of these is a default, not an error of an unusually careless clinician. That is the point of the module: the safe pathway is the one that has to be forced, and the screening tool is the thing that forces it.
How much of silver trauma care rests on trials designed for older people? Very little — most of the guidance is extrapolated from younger trauma populations or built on observational and registry data. What follows is the evidence behind the main decisions: the epidemiology that reframed the problem, the physiology thresholds, the under-triage, and the two drug questions where trials speak directly.
The evidence map
The strength column is this module’s appraisal, not a published grade.
| Question | Best evidence | Design | Strength |
|---|---|---|---|
| Has major trauma become a disease of older people? | Kehoe 2015; TARN 2017 | National registry analyses | Strong for the trend; descriptive |
| Where should the physiology alarms sit? | Heffernan 2010 | Single-centre retrospective, >4,000 patients | Moderate — consistent, not prospective |
| Are older patients under-triaged? | Alshibani 2021 | Systematic review, 23 studies | Moderate — consistent direction, heterogeneous |
| Do rib fractures carry excess mortality? | Meta-analysis cited by LMTS | Pooled observational | Moderate — large, but observational |
| Does TXA help the injured brain? | CRASH-3 | Large RCT | High — but benefit only in mild-moderate TBI |
| Should you give platelets for an antiplatelet head bleed? | PATCH | RCT (spontaneous ICH) | High for spontaneous; indirect for trauma |
| Does frailty predict outcome better than age? | Hamidi/Joseph 2019 | Prospective, 341 patients | Low–moderate — single centre |
The demographics of major trauma inverted in a generation
Kehoe and colleagues interrogated the entire TARN database from 1990 to 2013. The change is not subtle.
| Mean age | 36.1 (1990) → 53.8 (2013) |
| Largest single age group by 2013 | 25–50 (27.1%), closely followed by >75 (26.9%) |
| Commonest mechanism by 2013 | Low falls (<2 m), 39.1% — displacing road traffic collisions |
| CT use | 33.6% (1990) → 86.8% (2013) |
TARN, Major Trauma in Older People (2017)
The 2017 TARN report reviewed 8,176 patients aged 60 and over with an Injury Severity Score above 15, admitted in 2014. Its findings are quoted verbatim in the decision tool’s reference panels; the essentials:
- Over-60s now account for more than half of the severely injured in the database, and a fall from standing height is the commonest type of major trauma.
- A cascade of under-recognition — poor pre-hospital triage → low pre-alert → low activation → junior initial care → delayed investigation and treatment.
- Consultant involvement was near 100% with a positive pre-hospital triage, but ~40% (day) and ~30% (night) where triage was negative or not done.
- 3.2% were admitted directly to a medical ward (1.7%) or fell as inpatients (1.3%) — a group that never triggers a trauma call.
Heffernan 2010 — normal vital signs are unreliable in geriatric blunt trauma
A single Level 1 centre modelled mortality against presenting heart rate and blood pressure in 2,194 geriatric (≥65) and 2,081 young (17–35) blunt trauma patients.
| Mortality | 11.4% geriatric vs 2.4% young |
| Heart rate at which mortality climbs | >90 bpm in the elderly; not until 130 bpm in the young |
| Systolic at which mortality climbs | <110 mmHg in the elderly; not until 95 mmHg in the young |
| Authors’ recommendation | “New trauma triage set points of HR >90 or SBP <110 mm Hg should be considered in the geriatric blunt trauma patients.” |
Alshibani 2021 — under-triage of older trauma patients
A systematic review of prehospital triage for older trauma patients (23 of 280 screened studies) reached three conclusions: current trauma triage guidelines have poor sensitivity to identify major trauma and the need for trauma-centre care in older adults; modified tools improve sensitivity but at the cost of specificity, or are not applied to everyone; and the impact of under-triage on outcomes remains uncertain.
Rib fractures and mortality in older people
LMTS cites “a meta-analysis of 50,000 patients, including 15,000 people aged over 65 years” giving an odds ratio for mortality of 1.98 for those over 65 with any rib fractures, and 2.02 at all ages with three or more rib fractures. Ten per cent of older major trauma patients have rib fractures and up to half are missed on plain X-ray. LMTS pp.17–18
CRASH-3 — tranexamic acid in traumatic brain injury
A placebo-controlled trial of TXA (1 g over 10 min, then 1 g over 8 h) in acute TBI across 175 hospitals in 29 countries.
| Head injury death, ≤3 h (primary) | 18.5% TXA vs 19.8% placebo — RR 0.94 (95% CI 0.86–1.02), not significant |
| Mild-to-moderate TBI subgroup | RR 0.78 (95% CI 0.64–0.95) |
| Severe TBI subgroup | RR 0.99 (95% CI 0.91–1.07) |
| Vascular occlusion / seizures | No excess with TXA |
PATCH — platelet transfusion in antiplatelet-associated ICH
An open-label, masked-endpoint trial across the Netherlands, UK and France, in patients on antiplatelet therapy with acute spontaneous intracerebral haemorrhage.
| Death or dependence at 3 months | Adjusted common OR 2.05 (95% CI 1.18–3.56, p=0.0114) — worse with platelets |
| Serious adverse events in hospital | 42% (platelets) vs 29% (standard care) |
| Conclusion | “Platelet transfusion cannot be recommended for this indication in clinical practice.” |
Frailty scores predict outcome — better than age
A prospective comparison of four frailty scores in geriatric trauma patients (mean age 76, median ISS 13) found the Trauma-Specific Frailty Index and the Rockwood Frailty Score had a relatively strong predictive ability for mortality, complications, skilled-nursing-facility discharge and readmission — outperforming the modified Frailty Index and the Frailty Score. The authors proposed the TSFI, being easy to calculate, as a universal geriatric trauma frailty score.
Critical appraisal
- The strongest evidence is descriptive. Kehoe and TARN establish, beyond doubt, who the population is. Neither can show that a silver trauma pathway improves outcome — that trial has not been done, and probably will not be.
- The physiology thresholds are coherent but not prospectively validated. Heffernan’s HR 90 / SBP 110 set points come from retrospective single-centre modelling. They are widely adopted because they are sensible, not because a trial proved they save lives.
- Under-triage is real; its consequences are assumed. Alshibani shows the triage tools miss older patients, but the review is candid that the outcome impact of fixing that is “still uncertain.” A wider net has a specificity cost that is borne by the many uninjured older people it also catches.
- The two drug trials speak to older patients only indirectly. CRASH-3 and PATCH are good trials, but CRASH-3’s brain benefit is confined to mild-moderate injury and PATCH studied spontaneous, not traumatic, ICH. Both are used here as the best available evidence, with their limits stated.
- Frailty tools predict, but do not yet direct. The frailty literature is prognostic; it tells you the risk, not the intervention. The guidelines are unanimous that it must not be used to withhold care.
- Almost nothing here was designed around older people. The reversal doses, the transfusion ratios, the TXA regimen and the imaging rules are extrapolated from adult trauma populations. That extrapolation is reasonable and universal, but it is extrapolation.
- The guidance is UK-specific in its operational detail. The LMTS timings (one-hour reversal, two-hour C-spine clock, four-hour SCI referral) and the RCEM standards are service specifications; your network may differ, and that is the version you will be audited against.
Silver trauma is the best-evidenced problem and the least-evidenced solution in this hub. That an older person falling from standing is now the commonest major trauma, and that the system under-recognises them, is as close to established fact as trauma epidemiology gets. What to do about it is largely sensible extrapolation and guideline consensus rather than trial-proven benefit. The screening tool is worth using not because a randomised trial says so, but because the failure it prevents — a survivable injury missed by a system looking for the wrong patient — is common, serious, and documented.
What this is, and what it is not
The Decision tool implements the Pan-London older people’s trauma screening tool and quotes it, TARN, RCEM and NICE verbatim; it was internally audited in September 2026. The Teaching and Evidence tabs are different in kind: they are the author’s synthesis of those guidelines and the primary studies, written to explain the tool, not to extend it. Nothing in them changes what the tool tells you to do. Where they go beyond the guidelines, the source is named and tagged.
What this module deliberately does not do
- It does not calculate the Clinical Frailty Scale. The CFS is a licensed instrument with its own descriptors and training requirements — use your department’s copy. This tool points to where frailty scoring fits, not a score.
- It is not a full dosing reference. A few outline doses appear where the teaching would be incomplete without them (e.g. anticoagulant reversal), but the definitive dosing — TXA, opioid and fluid regimens included — is not given here; use the reversal module, the drug monographs, the paediatric tool and your local major haemorrhage protocol.
- It reproduces one screening tool — the Pan-London one. Your network may use a different tool with different thresholds, and that is the one you will be audited against.
- It does not replace the trauma team, the geriatrician or the specialist services it repeatedly tells you to involve.
- It does not quote the trauma course manuals. ATLS, the European Trauma Course and the UK frailty-and-older-trauma courses teach these principles, but they are copyrighted and are not reproduced here; the verifiable sources are the guidelines and studies listed below.
