Morbidity Measures in PSM: Incidence Density, Cumulative Incidence & Prevalence (Exam-Oriented)

Still using “incidence” and “prevalence” interchangeably? In one crisp session, we’ll fix that forever—with clean formulas, visuals, and outbreak examples you can redraw in exams and nail MCQs. What you’ll learn ✅ Core definitions & units Cumulative Incidence (Risk): new cases / population at risk (over a period) Incidence Rate (Incidence Density): new cases / person-time Prevalence (burden): Point (at an instant) vs Period (over an interval) Numerator/Denominator hygiene Exclude existing cases from incidence denominator; include them in prevalence Deal with closed vs dynamic cohorts and losses to follow-up Relationship & intuition P ≈ I × D (steady state, rare disease, stable I & D) How incidence and duration push prevalence up/down (treatment ↑ → duration ↓ → prevalence ↓) Outbreak metrics Attack Rate (AR) = new cases / population at risk (×100) Secondary Attack Rate within contacts/households When to use what Incidence → etiology, risk, causal inference, vaccine efficacy Prevalence → burden, resource planning, screening needs Graph & diagram you can redraw Flow sketch: population at risk → new cases (I) → prevalent pool (P) → exits (recovery/death) Rapid MCQ traps Which uses person-time? (Incidence rate) Which changes with duration? (Prevalence) Point vs Period prevalence in wording of stems AR is a type of incidence (not prevalence) 3rd Prof Buster 1.0 (ENT • Ophthal • PSM • FMT)—a 4-month LIVE program with 1-year recording access, color-coded notes, PYQs, and viva boosters. 👉 Enroll now on the MedLive App to unlock: Structured timetable + doubt-clearing live sessions Color-coded, exam-synced notes & rapid-revision PDFs PYQ banks, topic tests, mini-mocks Combo plans with 2nd Prof Buster 2.0 for integrated prep 📲 Download “MedLive by Dr Priyanka” on Android & iOS (search the app name) and pre-book today. #medlive #drpriyankasachdev #NEETPG #FMGE #neetpg2023 #MBBS #MedicalSchool #Doctor #NEET #NEXT #HowtostudyMBBS #2ndYearMBBS
