ABPM Occupational Medicine study guide
ABPM Occupational Medicine · Work through your exam, one topic at a time.
Board certification in Occupational & Environmental Medicine (OEM) is offered by the American Board of Preventive Medicine (ABPM) to physicians who protect and promote the health of working populations. The specialty addresses workers' capacity to perform work, the physical, chemical, biological, and social environments of the workplace, and the health outcomes of environmental exposures, including prevention and management of occupational and environmental injury, illness, and disability. Candidates qualify through several routes - an ACGME- or RCPSC-accredited OEM residency, a complementary mid-career pathway, or the special pathway for current ABPM diplomates - each with its own clinical training, graduate coursework, and practice requirements. The certification exam is the final step: 200 multiple-choice, single-best-answer questions with four or five responses, delivered in four one-hour blocks over 4 hours and 30 minutes, including a 15-minute tutorial and a 15-minute break. Topics on this exam: Core Preventive Medicine and Occupational & Environmental Medicine specialty content. The ABPM Occupational Medicine study guide has 2 sections and about 605 words.
01Core Preventive Medicine: Epidemiology, Screening, and Prevention for the Occupational Physician
Core preventive medicine tests whether you can reason from study design to causal inference to action . Know the measures cold: incidence vs. prevalence (prevalence = incidence × duration), attack rate for outbreaks, relative risk for cohort studies, odds ratio for case-control studies, and attributable risk as the exposure-attributable fraction of disease. Distinguish sensitivity (rules out disease when negative) from specificity (rules in disease when positive), and predictive values, which shift with prevalence-a common trap when applying a screening test to a low-prevalence workforce.

Occupational medicine questions revolve around the exposure–dose–response–effect chain. Know routes of entry (inhalation, dermal, ingestion), the difference between exposure monitoring (air sampling) and biological monitoring (internal dose, e.g., blood lead, urinary metabolites), and the role of occupational exposure limits (TWA, STEL, ceiling). Understand that limits are not bright lines between safe and unsafe-they are risk-management tools. Periodic health surveillance targets workers at risk: audiometry for noise, spirometry for dusts and vapors, skin checks for contact sensitizers, and biological monitoring where absorption occurs.
