Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

A. RESEARCH-TO-SCHOLARSHIP OPERATING SYSTEM

StageCore decisionRequired output
1. Question + stakeholdersDefine the patient/population, exposure/intervention, comparator, outcome or phenomenon; include relevant patient/community perspective.One answerable question + why it matters.
2. Design matchSelect experimental, observational, diagnostic, qualitative, evidence-synthesis or improvement design based on the question.Design capable of answering the question - not merely using available data.
3. GovernanceDetermine research vs QI/program evaluation; human-subjects status; privacy/data-use requirements; local approvals.Written institutional determination/approval before regulated work starts.
4. ProtocolPredefine variables, outcomes, confounders, eligibility, sampling, analysis, data management and roles.Versioned protocol + analysis/data plan.
5. Execute + documentCapture data consistently; log deviations, missingness, code versions and decisions.Auditable dataset + provenance trail.
6. Analyze + interpretEstimate effects/associations with uncertainty; test assumptions; separate confirmatory from exploratory work.Claims proportional to design and evidence.
7. DisseminateUse the reporting guideline, authorship/contributorship rules, transparent disclosures and appropriate venue.Abstract/poster/manuscript that another team can understand and evaluate.

B. QUESTION -> DESIGN MAP

QuestionTypical design familyKey caution
Does an intervention cause benefit/harm?Randomized trial when feasible; otherwise carefully designed comparative observational study.Feasibility does not erase confounding.
What predicts future outcome?Prospective/retrospective cohort.Separate prediction from causal inference.
What exposures are associated with a rare outcome?Case-control.Control selection can create major bias.
How common is a condition/exposure now?Cross-sectional/prevalence study.Temporal sequence is often limited.
How accurate is a test?Diagnostic-accuracy study with appropriate reference standard.Spectrum/verification bias can distort performance.
How do people experience a process?Qualitative or mixed-methods study.Sampling and analytic rigor still matter.
What does the total evidence show?Systematic review +/- meta-analysis.Protocol/search completeness and heterogeneity matter.
Can a local care process improve?QI/improvement study with iterative measurement.Obtain the appropriate institutional determination; publication intent alone does not define research.
