Psychiatric Patient Length of Stay in the Emergency Department Following Closure of a Public Psychiatric Hospital.

BACKGROUND: Psychiatric patient boarding in the emergency department (ED) is a ubiquitous problem associated with increased morbidity and mortality. OBJECTIVE: We evaluate the effect of closing a public psychiatric facility in a major metropolitan area on the ED length of stay (LOS) of psychiatric patients. METHODS: This was a retrospective chart review at two metropolitan EDs of all patients assessed to require inpatient psychiatric hospitalization. The time of arrival, time of disposition, time of transfer, insurance status, and accepting facility type were collected prior to and following the closure of a local inpatient psychiatric facility. RESULTS: We analyzed a total of 1107 patients requiring inpatient psychiatric hospitalization, with 671 patients who presented prior to the closure of the closest public psychiatric facility and 436 patients that presented following the facility closure. Following hospital closure, patients with private insurance (620 min before, 771 min after) and Medicare/Medicaid (642 min before, 718 min after) had statistically significantly longer ED LOS, as well as patients transferred to a private psychiatric hospital (664 min prior, 745 min after). However, overall ED length of stay following hospital closure for transfer of all psychiatric patients requiring inpatient hospitalization was not found to be statistically significant (1017 min prior, 967 min after). CONCLUSION: There was a statistically significant increase in ED LOS for patients with private insurance, Medicare/Medicaid, and for those patients transferred to a private psychiatric facility following closure of a public mental health hospital; however, overall, ED LOS was not increased for patients transferred to an inpatient psychiatric facility. This study highlights the significant impact that the closure of a single inpatient psychiatric facility can have on nearby EDs. We hope to bring attention to the need for increased psychiatric services during a time when there is a nationwide trend toward the reduction of available inpatient psychiatric beds.
