By City News Service Apr 6, 2021 PASADENA (CNS) - The vast majority of patients make their end-of-life care wishes known to loved ones, and nearly 90% of the time those wishes were carried out, according to a Kaiser Permanente study published today in the medical journal JAMA Network Open. “There is a common perception that people don't often document or tell others about their end-of-life wishes,'' said the study's lead author, David Glass, a research scientist at the Kaiser Permanente Southern California Department of Research & Evaluation and lecturer in the Department of Health Systems Science at the Kaiser Permanente Bernard J. Tyson School of Medicine.
