The Joint Commission identifies inpatient suicide as a sentinel event. Little is known about the epidemiology of hospital suicides other than that they are rare and occur mostly in psychiatry wards. Researchers examined two national databases to develop the first data-driven appraisal of hospital suicide rates. Nationally, between 49 and 65 hospital suicides occur each year. Nearly 75% happen during psychiatric treatment, and the most common means of death is hanging. This hospital suicide rate is an order of magnitude lower than prior estimates. An accompanying editorial raises concerns about the much larger epidemic of suicide immediately after psychiatric hospital discharge. A prior WebM&M commentary highlighted additional strategies to reduce hospital suicide risk.
