No adverse impact of depressive symptoms on the effectiveness of postacute care service: a multicenter male-predominant prospective cohort study.

ABSTRACT

BACKGROUND: Although the clinical effectiveness of community hospital-based postacute care (PAC) services has been shown, little was known regarding the impact of depression on the clinical outcomes of older patients receiving PAC services in Taiwan. METHODS: From January 2009 to August 2010, patients aged 65 years and older referred from tertiary medical centers or acute wards of community hospitals to PAC units were invited for study. All patients received the 4-week Comprehensive Geriatric Assessment-based intervention program in the PAC units. The functional assessment was composed of Geriatric Depression Scale-Short Form (GDS), Mini-Mental Status Examination, Barthel Index, Instrumental Activities of Daily Living, and Braden Score. RESULTS: Among the 401 participants (mean age, 82.0 years; 95.5% males), 66 (16.5%) patients were depressed at PAC unit admission. Depressed patients had significantly lower Barthel Index (38.1 ± 2.4 vs. 47.6 ± 1.2, p = 0.002) and Braden Score (17.7 ± 0.3 vs. 18.8 ± 0.2, p = 0.004) than nondepressed patients. Improvement was noted on all measures of functional outcome among patients receiving PAC services. Furthermore, GDS was significantly improved in depressed patients (from 6.4 ± 0.2 to 2.8 ± 0.2 in depressed patients vs. from 1.6 ± 0.1 to 0.9 ± 0.1 in nondepressed patients, p < 0.001). CONCLUSION: Depression was common when patients were newly admitted to PAC services, which was highly associated with poorer physical function. Improvement in physical function and depressive symptoms among all patients after PAC service was found, and the presence of depressive symptoms at PAC admission did not predict any adverse outcome of PAC services.
