Geriatric patients improve as much as younger patients from hospitalization on general psychiatric units

To determine whether geriatric patients aged 65 and older on general adult psychiatric units improve as much as younger patients, over what duration their improvement occurs, and their risk of readmission.

Cohort study.

Inpatient psychiatric unit of an urban, university-affiliated, county hospital from January 1993 through August 1999.

A total of 5,929 inpatients.

Standardized, routine assessments by attending psychiatrists included the Psychiatric Symptom Assessment Scale (PSAS) on admission and discharge. Discharge scores, length of stay (LOS), and risk of readmission within 1 year were modeled for the groups using multiple regression analyses.

Geriatric patients constituted 5% (n=299) of the 5,929 admissions. In multivariate analysis, geriatric status was not associated with discharge PSAS scores. Median LOS was longer for geriatric patients (16 days) than younger patients (10 days, P<.001), especially in older women (14 days) and geriatric patients with mild medical illness severity (13 days vs 11 days in those with moderate-to-severe medical illness). Geriatric patients were as likely to be readmitted within 1 year of discharge as younger patients.

Geriatric patients on general inpatient psychiatry units improved as much as younger patients. Their longer LOS was associated with milder medical illness severity. There may be a role for more specialized care of elderly women or geriatric patients with mild to moderate medical illness to improve the efficiency of their care.
