U.S. soldiers who have undergone inpatient psychiatric treatment have a greatly increased risk of suicide in the year after they are discharged from the hospital, suggests a new study.
The suicide rate in the U.S. Army is higher than the civilian rate, HealthDay reports.
The study included more than 40,000 active-duty soldiers who received inpatient psychiatric treatment between 2004 and 2009. Within a year of being discharged, 68 of the soldiers committed suicide—12 percent of all U.S. Army suicides during this period.
The researchers identified the 5 percent of soldiers with the highest predicted risk of suicide in the year after hospital discharge. This group of soldiers accounted for 52.9 percent of suicides after hospitalization. Among the soldiers with the highest risk of suicide, risk factors included being male, enlisting at a later age, criminal offenses, weapons possession, previous suicide attempts, and a greater number of antidepressant prescriptions filled in the past year.
