Impact of a natural disaster on a psychiatric inpatient population: clinical observations.

Abstract

Natural disasters do not always lead to post-traumatic stress disorders (PTSD) for their victims, although stress-related symptoms are commonly reported as results of such disasters. The impact of a natural disaster on the treatment of a hospitalized psychiatric population has never been systematically evaluated. In the fall of 1986, severe river flooding caused evacuation of a 160-bed psychiatric facility. One hundred and twenty-one hospitalized patients were taken to nearby hospital facilities, and many were separated from their primary therapists, fellow patients or both. A mail survey two months post-evacuation assessed stress-related symptoms, the patients' opinions of the impact of the flood on their treatment and functioning, and the patients' views of the evacuation procedures. Patients also responded to questions about their cognitive and affective reactions during each phase of the disaster. Clear evidence of PTSD was not found with this population; however, the findings underscore the importance of keeping patients with familiar staff and peers when possible. Differences between this study and previous disaster studies are noted, and suggestions for coping with natural disasters in inpatient or residential psychiatric facilities are offered.
