ABPMR SCI Medicine common mistakes
ABPMR SCI Medicine · Understand the traps and how to avoid them.
Assigns AIS A after finding absent light touch and pinprick at S4-5 without ever performing the digital rectal exam for deep anal pressure, then building a care plan around a 'complete' injury.
Candidates treat sacral light touch/pinprick as the whole sacral-sparing exam and skip the rectal exam because it feels awkward or is omitted from simplified checklists; deep anal pressure can be the only preserved sacral function, and its presence alone disqualifies AIS A.
What to do instead
Perform and document the full sacral exam on every patient: light touch and pinprick at S4-5 plus a digital rectal exam for deep anal pressure and voluntary anal contraction. Memorize the rule that AIS A requires absence of all sacral sparing (DAP, voluntary anal contraction, S4-5 light touch, S4-5 pinprick); if any one is present, the injury is incomplete.
Records a zone of partial preservation in a patient who is AIS B, C, or D, or merges the ZPP into the neurologic level of injury when stating the diagnosis.
The ZPP and the NLI are taught together and both reference 'levels below the lesion,' so candidates conflate them, forgetting that ZPP is defined only for AIS A and is reported as separate sensory and motor values.
What to do instead
State the NLI (single sensory and single motor level) plus AIS grade as the primary diagnosis. Only when the grade is A, add motor and sensory ZPP, defined as the most caudal segment with partially preserved function, and confirm no sacral sparing is present before using the term at all.
Explains new weakness, ascending sensory loss, or worsening spasticity years after injury as 'normal aging with SCI' or a spasticity flare, and adjusts medications without imaging.
Late deterioration is uncommon but consequential, and the gradual tempo makes it easy to anchor on benign explanations; candidates also assume the neurologic exam is static after the first year.
What to do instead
Treat any new or ascending neurologic deficit, new pain pattern, or change in bowel/bladder function as an indication for MRI of the spine. Consider post-traumatic syrinx, tethered cord, and, in patients with a shunt, shunt malfunction or hydrocephalus; the exam question is which imaging study to order, not which drug to titrate.
Manages early hypotension after acute SCI with large-volume crystalloid boluses alone and attributes bradycardia or suction-induced asystole to anxiety or hypoxia without preparing for it.
Candidates apply trauma resuscitation reflexes and label all shock as hemorrhagic, forgetting that neurogenic shock is a distributive state with relative hypovolemia from loss of sympathetic tone, and that unopposed vagal tone makes these patients bradycardic.
What to do instead
After hemorrhage is excluded, target MAP roughly 85-90 mmHg for about a week using vasopressors (norepinephrine or phenylephrine) rather than continued fluids, and avoid fluid overload. Anticipate bradycardia with tracheal suctioning, hypoxia, or position changes; preoxygenate, use atropine or a chronotrope when needed, and keep the patient warm and adequately volume-resuscitated.
When a patient with a T4 injury develops a pounding headache with BP 180/110, gives an oral antihypertensive first and only later looks for a cause, or dismisses autonomic dysreflexia because the lesion is below T6.
Candidates memorize the drug list but not the ordered algorithm, and they overestimate the threshold level, not recalling that dysreflexia occurs in lesions at T6 and above (occasionally slightly lower) because splanchnic outflow is still intact.
What to do instead
Follow the sequence: sit the patient upright, loosen constrictive clothing and devices, then check the bladder first (kinked catheter, retention, UTI) and bowel (impaction) before moving to skin, nails, and other noxious stimuli. Use short-acting agents such as nitroglycerin or nifedipine only if BP remains elevated after stimulus removal, monitor for rebound, and discharge the patient with a written dysreflexia action plan.
States that a C6 patient with good tenodesis will be independent with bowel care and pressure relief but needs assistance with feeding, or predicts that a C5 patient will transfer independently with a sliding board.
Candidates learn level-based outcomes as a vague ladder and lose track of which specific muscles are innervated at each level, so they shift functions up or down by one level.
What to do instead
Anchor each expectation to key muscles: C5 has deltoid and biceps (feeding with adaptive equipment, no antigravity elbow extension, dependent transfers); C6 has wrist extensors and tenodesis grasp (assisted to supervised sliding board transfers, independent pressure relief, possible self-catheterization with setup); C7 has triceps (independent transfers, self-catheterization, driving with adaptations). Rehearse a level-by-level functional table and justify each prediction by naming the innervated muscle.
Prescribes a suppository-and-digital-stimulation bowel program for a patient with a conus medullaris or cauda equina lesion, or recommends manual evacuation as first-line for a patient with a reflex bowel above the conus.
Candidates apply one standard bowel protocol to all patients without determining whether the reflex arc is intact, even though the exam findings that separate upper from lower motor neuron bowel are simple and reliable.
What to do instead
Test the bulbocavernosus and anal wink reflexes and assess rectal tone. If the reflex arc is intact, use a scheduled reflex program with suppository and digital stimulation; if it is absent, use manual evacuation, Valsalva, and abdominal massage, and consider a colostomy for refractory cases. State the reflex status explicitly in the rationale.
Diagnoses and treats a urinary tract infection in a patient on clean intermittent catheterization who has cloudy, odorous urine and pyuria but no fever, new incontinence, suprapubic pain, or autonomic dysreflexia.
Candidates carry over the ambulatory paradigm in which pyuria plus symptoms equals infection, not realizing that chronic pyuria and bacterial colonization are expected in neurogenic bladder managed with catheters.
What to do instead
Reserve treatment for compatible signs or symptoms after excluding other sources, and do not screen for or treat asymptomatic bacteriuria except in pregnancy or before urologic procedures involving mucosal trauma. When infection is suspected, obtain a specimen before starting antibiotics and choose agents based on prior cultures and resistance patterns.
Calls a sacral pressure injury with adherent slough 'stage 3' because it is not obviously down to bone, or labels a purple, intact, painful area over the ischium as stage 1.
Candidates stage by depth guessed from appearance rather than by the formal definitions, and they do not distinguish blanching erythema from the deep tissue injury pattern.
What to do instead
Use the standard definitions: stage 1 is intact skin with non-blanchable erythema; stage 2 is partial-thickness loss with a shallow open wound or intact serum-filled blister; stage 3 is full-thickness loss with visible fat but no exposed bone, tendon, or muscle; stage 4 exposes deep structures; unstageable means slough or eschar obscures the base and requires debridement before staging; deep tissue injury is an intact or blistered purple or maroon area. Never assign a pressure injury stage to mucosal surfaces.
Attributes depressed mood, insomnia, and withdrawal after discharge to inevitable grief, and completes the visit without a standardized mood screen, a direct question about suicidal ideation, or an assessment of caregiver burden and transportation barriers.
Candidates view psychological distress in SCI as expected and therefore not actionable, and they focus the visit on skin and bladder; time pressure pushes screening to the end, where it is dropped.
What to do instead
Administer a validated instrument such as the PHQ-9 at each transition of care and ask directly about suicidal ideation, since suicide risk is elevated in this population; document the response and refer when indicated. Pair this with explicit questions about caregiver strain, home equipment, transportation, and return to work or school, and route patients to peer support or vocational resources rather than waiting for the next annual visit.
