Listen to UpToDate — Turn Clinical Topics into Audio

UpToDate is the most widely used clinical decision support resource in the world, trusted by over 2 million clinicians across 190+ countries. Its evidence-based topics are continuously updated by physician authors who synthesize the latest research into actionable recommendations graded by evidence quality. For hospitalists, primary care physicians, specialists, and trainees, UpToDate is often the first reference consulted at the point of care.

Each UpToDate topic is comprehensive — typically 5,000 to 15,000 words covering epidemiology, pathophysiology, clinical manifestations, diagnosis, treatment, and prognosis. The Summary and Recommendation sections distill key takeaways, but clinicians frequently need the full topic for nuanced cases. Reading a complete topic takes 20 to 40 minutes of focused screen time, which is difficult to find during a busy clinical day.

CastReader adds text-to-speech to UpToDate as a free Chrome extension. Open any topic on uptodate.com, click the extension icon, and listen to the clinical content read aloud with natural AI voices. Each paragraph highlights as it's spoken, so you can follow along or listen hands-free during commutes, rounds preparation, or charting breaks.

For physicians preparing for board certification or maintenance of certification exams, UpToDate is a primary study resource. CastReader transforms board review into an audio experience — listen to UpToDate topics during your commute, at the gym, or while doing household tasks. At 1.5x speed, a 30-minute topic becomes 20 minutes of listening that can overlap with other activities.

CastReader's adjustable speed and paragraph navigation are designed for clinical workflows. Jump directly to the treatment section of a topic. Slow down for complex drug dosing tables. Speed up through background sections you already know. Combined with the Send to Phone feature for mobile listening, CastReader makes UpToDate accessible wherever your clinical day takes you.
