 Reframing Hope in Pediatric End-of-Life Care 150 150 Tiasha Letostak, PhD
By: Tiasha Letostak, PhD

As physicians, you want to do more good than harm. And it is often believed that telling the truth about poor end-of-life expectations will lead to hopelessness in patients and families, causing more harm than good. But study after study on prognostication has shown that patients and their families prefer more honest and accurate communication.…
