Current Medical Diagnosis & Treatment 2026

The most widely-used clinical reference in internal medicine. Updated annually, Current Medical Diagnosis & Treatment 2026 by Maxine A. Papadakis, Michael W. Rabow, and Kenneth R. McQuaid delivers practical, evidence-based diagnosis and treatment guidance across every major clinical specialty.

While First Aid is the spine of Step 1 prep, CMDT is the spine of Step 2 CK and your clinical years. It bridges the gap between basic-science knowledge and the diagnostic and therapeutic reasoning tested on Step 2 — and used in actual residency.

What's inside:

• Annually updated coverage of every major medical specialty
• Evidence-based diagnostic and treatment recommendations
• Year-in-review section highlighting new guidelines and developments
• Practical tables, algorithms, and decision-support content

Who this is for: medical students moving from Step 1 to Step 2 CK, IMGs preparing for clinical rotations or US clinical experience (USCE), and residents who want a single reliable internal medicine reference.

Read our breakdown of why Step 2 CK is now the most important number on your IMG residency application.
