ABPN Pain Medicine common mistakes
ABPN Pain Medicine · Understand the traps and how to avoid them.
Committing to a single diagnosis (for example, lumbar radiculopathy) after the first plausible pattern and not re-evaluating when the history includes red flags such as bowel or bladder dysfunction, fever, or progressive weakness.
Pattern recognition from high-frequency cases and time pressure lead candidates to underweight can't-miss diagnoses.
What to do instead
Use a forced differential checklist and a red-flag screen (cauda equina, epidural abscess, malignancy, fracture) before finalizing; document why each is excluded.
Performing opioid equianalgesic conversions by direct table substitution without adjusting for incomplete cross-tolerance, especially with methadone or transdermal fentanyl.
Memorized tables suggest linear conversion, but guidelines require dose reduction, and methadone's nonlinear pharmacology is counterintuitive.
What to do instead
Apply a structured protocol: calculate the equianalgesic dose, reduce by 25-50%, reassess, use methadone-specific conversion, and never start fentanyl patches in opioid-naive patients.
Treating urine immunoassay results as definitive, such as calling a positive amphetamine screen methamphetamine use or missing synthetic opioids because they are not on the standard panel.
Immunoassays cross-react with common drugs and have limited panels; candidates conflate screening with confirmation.
What to do instead
Confirm unexpected positives with GC-MS or LC-MS, know common cross-reactants, and order targeted testing for synthetic opioids when clinically suspected.
Scheduling an epidural steroid injection or facet block without systematically screening anticoagulants, active infection, contrast allergy, or pregnancy.
Attention shifts to needle technique and image guidance, so pre-procedure safety is treated as clerical.
What to do instead
Complete a standardized pre-procedure checklist covering anticoagulation hold times per ASRA guidance, infection, allergy, pregnancy, and renal function before obtaining consent.
Misidentifying spinal levels or laterality during fluoroscopically guided procedures, for example counting from the sacrum without a full-length confirmatory view or confusing cervical nerve root with vertebral levels.
Rote memorization without fluoroscopic landmark practice, plus anatomical variants and display orientation, causes errors.
What to do instead
Practice level counting on teaching fluoroscopy, confirm with full-length views and contrast, and state the level and laterality aloud before injection.
Attributing poor treatment response or disproportionate pain behavior to secondary gain without screening for depression, PTSD, catastrophizing, or opioid misuse risk.
Biomedical training and implicit bias frame psychological factors as outside pain medicine or as malingering.
What to do instead
Administer validated tools such as the PHQ-9, Pain Catastrophizing Scale, Opioid Risk Tool, and PCL-5, and integrate results into the formulation rather than labeling the patient.
Recommending bed rest or passive modalities such as TENS or ultrasound as primary treatment for chronic low back pain or CRPS instead of graded active rehabilitation.
Passive treatments are familiar, low-risk, and patient-requested, while evidence for active rehabilitation is underappreciated.
What to do instead
Prioritize graded exercise, functional restoration, and desensitization; use passive modalities only as adjuncts with explicit time limits.
Confusing multidisciplinary with interdisciplinary care, or failing to define team roles and shared goals when describing a pain program.
The terms are used interchangeably in practice, but the exam tests precise definitions and team function.
What to do instead
Memorize the distinction: multidisciplinary care involves parallel disciplines, while interdisciplinary care is an integrated team with shared assessment and plan; practice describing role delineation.
Obtaining informed consent by listing generic risks without documenting discussion of alternatives, including no treatment, off-label use, and procedure-specific complications.
Consent is treated as a signature, time pressure is high, and legal standards vary by jurisdiction.
What to do instead
Use a structured consent script covering diagnosis, nature of the procedure, alternatives, risks and benefits, off-label status, questions, and teach-back confirmation.
Misapplying controlled-substance rules, such as prescribing schedule II drugs across state lines without appropriate registration, ignoring PDMP requirements, or misstating DEA schedule classifications.
Regulations vary by state and change over time, so candidates rely on outdated rules of thumb.
What to do instead
Review current DEA registration exceptions, state PDMP mandates, and schedule classifications, and use a prescribing compliance checklist.
