New deterioration reopens the primary survey

A tertiary survey prevents delayed diagnosis but must never postpone immediate reassessment when airway, breathing, perfusion, consciousness, neurology or limb status worsens.

Action: Return at once to CABCDE, treat any life threat, compare with previous findings and interventions, call senior trauma support, and use targeted imaging or operative review before resuming the planned head-to-toe tertiary process.

Overview

Use repeated structured assessment, definitive report reconciliation and closed-loop handover to detect injuries obscured by resuscitation, altered consciousness, distracting pain or transfers.

A tertiary survey is a planned reassessment after the primary and secondary surveys, initial imaging and urgent treatment. Its purpose is to discover injury that was obscured or not yet apparent and to reconcile the entire clinical record. It is not simply a repeated form. Timing follows local trauma policy, often within twenty-four hours, with another examination after extubation, sobriety or adequate analgesia if the first tertiary assessment remains unreliable.

Begin with what has changed. Review pre-hospital mechanism and physiology, interventions, operations, transfusion, imaging, laboratory trends and new symptoms. Repeat ABCDE before detailed examination. A new oxygen requirement, falling haemoglobin, abdominal distension, reduced consciousness or limb neurovascular change triggers urgent problem-specific care. The tertiary survey must not normalise deterioration by labelling it expected after trauma or surgery.

Reconstruct history using AMPLE and collateral information. Confirm allergies, medicines—especially anticoagulants, insulin, steroids and antiepileptics—past disease, pregnancy possibility, last intake and exact events. Establish baseline cognition, mobility, neurological deficit and dominant hand. Ask about pain in areas not previously discussed, visual or dental symptoms, hearing change, numbness, weakness and inability to load a limb. Review safeguarding and self-harm concerns where mechanism or context suggests them.

The examination is systematic and comparative. Inspect and palpate scalp, face, mouth, neck, chest, abdomen, pelvis, perineum when indicated, spine and every limb. Map all wounds and bruises. Move joints only when safe, assess tendon function and named peripheral nerves, and document pulses, capillary refill and temperature. Check posterior surfaces with movement tailored to pelvic, spinal and haemodynamic risk. A painful immobilised joint still needs a plan for later examination.

Imaging reconciliation is central. Review scout, reconstructions and all imaged regions with the report, checking that clinical areas were covered and that a binder, splint or positioning did not conceal abnormality. Confirm that every preliminary interpretation has a final authorised report and every addendum reached the treating team. If focal signs conflict with imaging, discuss senior re-review, additional views, CT, MRI or ultrasound according to the suspected tissue rather than accepting a generic negative result.

Devices and treatments can create or conceal injury. Check tracheal tube and drain positions, line sites, splint pressure, binder duration, tourniquet time, catheter indication and skin beneath equipment. Reassess distal neurovascular findings after reductions and operations. Reconcile antibiotics, tetanus, thromboprophylaxis and home medicines. Ensure restrictions on weight bearing, spinal movement, feeding and therapy reflect the latest definitive diagnosis, not an obsolete provisional plan.

Close the loop through one current problem list. Classify each item as confirmed, excluded, still possible, incidental or treatment-related; assign a named specialty, action and deadline. Explain newly discovered injury and altered plans to the patient and family. At transfer, send images and final reports, not merely a summary. At discharge, provide red flags and appointments. Record delayed diagnoses transparently and review them through trauma governance to correct recurrent handover, imaging or examination failures.

Key points

  • Schedule a documented tertiary survey after initial resuscitation and imaging, commonly within 24 hours, and repeat when the patient is awake, sober or able to cooperate.
  • Start with interval events and another CABCDE review; any deterioration takes priority over completing the checklist and triggers immediate treatment.
  • Rebuild the mechanism and AMPLE history from patient, witnesses, ambulance and records, including anticoagulants, baseline function, pregnancy and pre-existing deficits.
  • Perform a complete head-to-toe examination with every limb exposed, wounds mapped and joint, tendon, nerve and distal perfusion findings compared with prior documentation.
  • Review all images, not only reports; reconcile preliminary and final interpretations, adequacy of coverage and clinical-radiological discordance with a senior radiologist.
  • Check tubes, lines, drains, splints, binder and pressure areas, and confirm that every device still has an indication, position check and removal plan.
  • Maintain a single problem list containing confirmed injuries, unresolved possibilities, incidental findings, pending tests and the named team responsible for each action.
  • At transfer and discharge, communicate final diagnoses, restrictions, warning signs and follow-up directly; audit delayed diagnoses to improve systems rather than conceal them.

Aetiology

01

Limited initial examination

Intubation, intoxication, pain, agitation, haemodynamic instability and immediate procedures prevent reliable history, palpation, movement and neurological testing during first assessment.

02

Distracting injury

A visible, painful or life-threatening lesion captures team attention and can hide less dramatic spine, limb, facial or internal injury.

03

Transition failure

Transfer between ambulance, scanner, theatre, critical care, ward and hospitals can lose provisional diagnoses, pending images, wounds and actions when handover lacks ownership.

04

Evolving pathology

Some bowel, vascular, compartment, intracranial and soft-tissue injuries become clinically or radiologically apparent only with time and repeated assessment.

Pathophysiology

  1. 1
    Masked nociception

    Sedation, analgesia, neuropathy and reduced consciousness suppress pain and guarding, while later waking reveals focal injury that existed at presentation.

  2. 2
    Progressive swelling

    Ongoing bleeding, reperfusion and inflammation increase compartment pressure and soft-tissue tension after an initially acceptable limb examination.

  3. 3
    Delayed physiological expression

    Slow haemorrhage, bowel leakage, pulmonary contusion and intracranial expansion can produce abnormal observations hours after the initial scan or procedure.

  4. 4
    Cognitive load

    Multiple injuries, competing teams and large volumes of data overwhelm unaided memory, making checklists, documentation and named responsibility essential safety controls.

Clinical features and red flags

Previously unreliable region

Sedation, intoxication, spinal precautions, distracting pain or urgent surgery made the first examination incomplete, so that area requires deliberate repeat assessment.

Clinical-imaging mismatch

Focal bony tenderness, swelling, neurological deficit or inability to bear weight despite a negative study suggests inadequate views, occult injury or wrong modality.

Evolving internal injury

Increasing abdominal pain, ileus, fever, lactate rise or haemoglobin fall after initially reassuring findings can indicate delayed bowel, vascular or solid-organ complication.

Developing compartment syndrome

Escalating pain, passive-stretch pain, tense swelling or new motor and sensory change requires emergency reassessment even after fixation or revascularisation.

Lost provisional diagnosis

A concern mentioned in ambulance or preliminary notes but absent from the active problem list should be treated as unresolved until explicitly evaluated.

Unowned incidental finding

A radiological abnormality unrelated to acute trauma still requires documented urgency, patient communication and named follow-up responsibility.

Red flags requiring action

  • New hypoxia, shock, falling GCS, focal deficit, escalating pain or loss of distal perfusion after admission represents active deterioration, not a routine tertiary-survey finding.
  • Persistent focal tenderness, swelling, inability to bear weight or unexplained anaemia despite negative initial imaging requires re-examination and senior radiology or specialty review.
  • An outstanding preliminary report, unreviewed transferred image, undocumented wound or uncertain ownership of an incidental finding is a system-level missed-injury risk requiring closure.

Investigations

  1. 01
    First-line record reconciliationFirst stepFirst line
    Why
    Identify incomplete assessments, pending results and discrepancies across transitions.
    Interpretation and limitations
    Compare ambulance, resuscitation, theatre, imaging and ward documentation; unresolved provisional findings remain active problems rather than being assumed negative.
  2. 02
    Definitive imaging-report reviewDefinitive
    Why
    Ensure every acquisition has an authorised interpretation and action.
    Interpretation and limitations
    Check final reports and addenda against preliminary decisions and examination; contact radiology directly for critical discrepancy or inadequate coverage.
  3. 03
    Targeted repeat radiographs
    Why
    Assess a newly localised skeletal or joint concern.
    Interpretation and limitations
    Use orthogonal and anatomically centred views including relevant joints; repeated generic films without a precise question add radiation without resolving discordance.
  4. 04
    CT for occult complex injury
    Why
    Define bone, chest, abdominal, pelvic or vascular injury missed or evolved after initial assessment.
    Interpretation and limitations
    Choose contrast and coverage with radiology according to the new clinical signal; physiological deterioration may require intervention rather than further diagnostic delay.
  5. 05
    MRI or ultrasound
    Why
    Evaluate cord, ligament, tendon, occult fracture or soft tissue after stabilisation.
    Interpretation and limitations
    Use the modality suited to the tissue and urgency, recognising MRI access and device safety and ultrasound's operator dependence.
  6. 06
    Serial laboratory trends
    Why
    Detect delayed bleeding, organ injury, infection and treatment complications.
    Interpretation and limitations
    Interpret haemoglobin, lactate, renal function, electrolytes, liver tests, inflammatory markers and coagulation in context; one unchanged value cannot clear evolving injury.

Differential diagnosis

01

Expected postoperative change

Pain, anaemia and reduced mobility may follow surgery, but disproportionate trajectory, new neurology or physiological instability requires exclusion of complication or missed injury.

02

Delirium

Medication, sleep loss, infection, retention and metabolic disturbance cause confusion, yet hypoxia, intracranial change and occult pain must be reassessed first.

03

Incidental chronic abnormality

Degenerative disease, healed fracture and longstanding neurological deficit can appear acute unless baseline history and previous imaging are obtained.

04

Hospital-acquired complication

Pneumonia, venous thrombosis, line infection, pressure injury and drug effects can mimic trauma progression and need parallel prevention and investigation.

Management

01TimingPrepare a reliable tertiary surveyFirst stepInitial resuscitation and urgent treatment are complete enough for systematic reassessment.+
  1. 1Schedule the survey within the trauma pathway and identify which regions or history remain unreliable because of sedation, pain, intoxication or urgent intervention.
  2. 2Collect ambulance, emergency, operative and transfer records, preliminary and final imaging reports, laboratory trends and current device lists before bedside review.
  3. 3Ask the patient and collateral sources for interval symptoms, baseline function and a reconstructed AMPLE history.
  4. 4If the patient cannot cooperate, document limitations and set a specific trigger and owner for repeat examination after waking or stabilisation.
02BedsideRe-examine and reconcileA suitably trained clinician can compare current findings with the complete record.+
  1. 1Repeat CABCDE and treat new deterioration immediately, then conduct a deliberate head-to-toe inspection, palpation, joint and neurovascular examination.
  2. 2Map wounds, inspect pressure areas and verify every tube, drain, line, splint, binder and catheter for position, indication and removal plan.
  3. 3Review images and authorised reports against each finding, obtaining radiology or specialty input wherever anatomy, symptoms and imaging disagree.
  4. 4Update one problem list with confirmed and possible injury, pending tests, incidental findings, responsible team and deadline.
03ClosureHandover and learnThe tertiary findings alter or confirm ongoing care and the patient is transferring or approaching discharge.+
  1. 1Communicate new diagnoses and changed restrictions to the patient, nursing, therapy and all responsible specialty teams with closed-loop confirmation.
  2. 2Provide the receiving setting with images, final reports, outstanding studies, device plans, medicines, weight-bearing status, warning signs and appointments.
  3. 3Arrange named follow-up for incidental findings and unresolved symptoms, including a method to act on results returning after discharge.
  4. 4Record delayed injuries in governance systems and review contributory examination, workload, imaging and handover factors to prevent recurrence.

Complications

01

Delayed definitive treatment

Unrecognised fracture, vascular damage, bowel injury or intracranial bleeding loses the optimal window for fixation, repair, decompression or antimicrobial control.

02

Permanent functional loss

Missed tendon, nerve, joint or spinal injury can heal incorrectly or progress, causing chronic pain, weakness, stiffness and reduced independence.

03

Repeated radiation and procedures

Failure to coordinate image review and clinical questions creates duplicated scans, unnecessary transfers and avoidable invasive investigation.

04

Communication harm

Patients may receive contradictory weight-bearing, wound, medication or follow-up advice when provisional and final diagnoses are not reconciled at discharge.

Monitoring and follow-up

  • Repeat the tertiary examination when consciousness, pain control or cooperation improves and after transfer if substantial parts remained unassessed.
  • Track every preliminary report to a final authorised report and document the clinician who acknowledged critical changes or addenda.
  • Trend observation, haemoglobin, lactate and organ-function changes that might signal occult bleeding or evolving internal injury.
  • Repeat distal neurovascular and compartment assessment after splint adjustment, reduction, fixation, revascularisation and any new pain increase.
  • Audit delayed diagnoses, unowned incidental findings and handover failures through the trauma governance programme and feed changes back to the team.

Special situations

Tertiary means comparative

The value comes from comparing serial findings, intervention effects and final reports, not performing another isolated examination.

Negative imaging has boundaries

A study answers only the anatomy, timing and technique acquired; new focal signs can justify another modality or expert re-review.

Waking creates information

Extubation and sobriety reveal pain, vision, hearing, tendon and neurological deficits hidden during the initial survey.

Devices deserve a survey

Binders, splints, collars, lines and drains can injure skin, compress nerves or migrate after their initial correct placement.

Governance completes prevention

Transparent review of delayed diagnoses identifies system design problems that individual vigilance alone cannot solve.

Common pitfalls

  1. 01

    Completing the tertiary checklist while ignoring new physiological deterioration that requires CABCDE.

  2. 02

    Assuming whole-body CT replaces examination of joints, tendons, skin and peripheral nerves.

  3. 03

    Failing to repeat an examination that was limited by intubation, intoxication or severe pain.

  4. 04

    Accepting a preliminary report without checking the authorised final interpretation and addenda.

  5. 05

    Listing an incidental finding without a named owner, urgency or patient communication plan.

  6. 06

    Handing over confirmed injuries while allowing unresolved suspicions and pending results to disappear.
