The Harriet Lane Handbook, 24th Edition: The Gold Standard in Pediatric Point-of-Care Reference for 70 Years

This indispensable resource provides fast, accurate, point-of-care guidance on pediatric diagnosis and treatment. Updated by residents, edited by chief residents, and reviewed by Johns Hopkins faculty, it covers everything from emergency management and toxicology to neonatology and biostatistics. Includes an eBook version with every purchase.

For 70 years, a small, portable book has stood as the silent partner to countless pediatric residents, nurses, and physicians across the world. Born from the prestigious halls of The Johns Hopkins Hospital, The Harriet Lane Handbook has earned its reputation not through marketing, but through relentless, practical utility.

The 24th Edition, published on April 17, 2026, arrives at a critical time in medicine. Recognized as a 2026 Doody's Core Title and an "Essential Purchase in Pediatrics," this edition moves beyond traditional disease management to embrace modern challenges like healthcare disparities, trauma-informed care, and vulnerable populations.

What Makes the 24th Edition a Critical Update?

Unlike standard textbooks, The Harriet Lane Handbook is meticulously revised every few years by the very people who use it most: residents at Johns Hopkins. The 24th edition introduces several major enhancements designed for today’s fast-paced clinical environment.

1. New Full-Color Outline Format

Gone are the days of dense monochrome text. The new full-color, outline format allows clinicians to find information in seconds—not minutes. Flowcharts, algorithms, and figures are now more accessible and impactful, crucial during emergencies or rounds.

2. Expanded Audio Case Files

A standout feature of this edition is the expanded audio case files. Users can listen to Johns Hopkins residents and faculty discuss real-world case studies and, importantly, healthcare disparities. This audio component transforms passive reading into active learning, perfect for commutes or pre-round preparation.

3. New Chapter: Vulnerable Populations & Trauma-Informed Care

Recognizing that pediatric care extends beyond biology, the 24th edition includes a dedicated chapter on Vulnerable Populations. It expands coverage on trauma-informed care, equipping practitioners with the skills to address social determinants of health, adverse childhood experiences (ACEs), and the unique needs of marginalized youth.

4. Updated Pediatric Drug Formulary

Pharmacology is the heart of pediatric safety. Carlton K. K. Lee, PharmD, MPH, has meticulously updated the comprehensive Pediatric Drug Formulary. This section provides the latest dosing, administration guidelines, and safety data for a wide range of medications, including adjustments for renal failure (Chapter 32).
