Patient Safety
Error types, root-cause analysis, quality improvement, and safety culture.
Lessons
Illustrated, high-yield walkthroughs of the patient safety concepts the boards test most.
A systems-based tour of patient safety: James Reason's Swiss Cheese Model, active vs. latent failures, and the slip–lapse–mistake–violation taxonomy, all anchored to the \"next best step\" the boards test (near miss → non-punitive report, sentinel event → RCA, proactive → FMEA) plus the event-severity ladder, the effectiveness hierarchy, Just Culture, and error disclosure.
Quality improvement is the prospective, systems-based discipline (PDSA to test changes, FMEA to anticipate failures), while root cause analysis is the retrospective, blame-free investigation triggered by a sentinel event. Boards test which tool to reach for and reliably reward the answer that redesigns the system over one that relies on vigilance or re-education.
Handoffs are high-risk care transitions where communication failures drive sentinel events; SBAR structures urgent clinical messages while I-PASS structures shift sign-out. Closed-loop read-back plus the two-challenge/CUS escalation tools are the board-favored, systems-level fixes over individual blame.
A board-focused walkthrough of medication reconciliation and the systems that prevent medication error: the four-step reconciliation workflow (BPMH → compare → reconcile → communicate), error taxonomy and definitions (error/near-miss/ADE/ADR), high-alert drugs and Tall Man lettering, the Joint Commission \"Do Not Use\" abbreviations, CPOE vs BCMA, and the just-culture/RCA-vs-FMEA framework — all delivered as the next-best-step and \"what would have prevented this\" decisions the exams test.
How the boards test informed consent (the 4 components of capacity, the elements of valid consent, exceptions, minors, and surrogate decision-making) and medical-error disclosure (prompt, honest, systems-based), all framed as next-best-step decisions anchored in patient autonomy.
A boards-focused lesson separating CMS Hospital-Acquired Conditions (the payment/present-on-admission rule) from NQF Never Events and Joint Commission sentinel events, with the tested next steps — honest disclosure, incident reporting, and root cause analysis — plus CLABSI/CAUTI prevention and the error taxonomy.
A board-focused walkthrough of how healthcare quality is measured (Donabedian structure/process/outcome, plus the Model for Improvement's balancing measures and the STEEEP aims) and improved (the Model for Improvement and rapid PDSA cycles), drilling the process-vs-outcome and RCA-vs-FMEA distinctions the exam loves to test as next-best-step decisions.
A boards-focused lesson on Just Culture — balancing system and individual accountability — and error-reporting systems, teaching how to classify human vs at-risk vs reckless behavior (Console/Coach/Punish), disclose harmful errors, and distinguish retrospective RCA from prospective FMEA. Emphasizes classic next-best-step decisions for STEP 2 CK and STEP 3.
