Emergency department patients with psychiatric complaints return at higher rates than controls

At our 35,000 visit/year emergency department (ED), we studied whether patients presenting to the ED with psychiatric complaints were admitted to the hospital at a higher rate than non-psychiatric patients, and whether these patients had a higher rate of reevaluation in the ED within 30 days following the index visit.

We reviewed the electronic records of all ED patients receiving a psychiatric evaluation from January to February 2007 and compared these patients to 300 randomly selected patients presenting during the study period for non-psychiatric complaints. Patients were followed for 30 days, and admission rates and return visits were compared.

Two hundred thirty-four patients presented to the ED and were evaluated for psychiatric complaints during the study period. Twenty-four point seven percent of psychiatric patients were admitted upon initial presentation versus 20.7% of non-psychiatric patients (p = 0.258). Twenty-one percent of discharged psychiatric patients returned to the ED within 30 days versus 13.4% of discharged non-psychiatric patients (p=0.041). Patients returning to the ED within 30 days had a 17.1% versus 21.6% admission rate for the psychiatric and non-psychiatric groups, respectively (p=0.485).

Patients presenting to this ED with psychiatric complaints were not admitted at a significantly higher rate than non-psychiatric patients. These psychiatric patients did, however, have a significantly higher return rate to the ED when compared to non-psychiatric patients.
