Utility of clinical characteristics in identifying depression in geriatricED patients

We will determine if clinical characteristics can be useful in identifying depression in geriatric Emergency Department (ED) patients. We have provide d a cross sectional observational study of geriatric patients presenting to an urban university-affiliate public hospital, A brief self rated depressi on scale (SRDS) was used to identify depression. Clinical characteristics, examined retrospectively, included chief complaint, chronic illnesses, mode and time of arrival and discharge disposition, Relative prevalence of depr ession was calculated for these clinical characteristics. 70 (27%; 95% CI, 22% to 32%) of 259 patients were found to be depressed by the SRDS, Patient s with nonspecific chief complaints were more commonly depressed than patie nts with system-specific chief complaints, but not significantly (relative prevalence 1.6; 95% CI, 1.0 to 2.4; p = 0.19). The relative prevalence of d epression also did not vary significantly when analyzed by specific chronic illness (P = 0.42) except cardiac disease (1.6;95% CI, 1.1 to 2.4), PM or night arrival (1.3; 95% CI, 0.8 to 2.0; p = 0.17), ambulance use (1.1; 95% CI, 0.7 to 1.7; p = 0.88), or need for medical admission (1.0; 95% CI, 0.7 to 1.5; p = 0.97). Depression is common in geriatric ED patients. Clinical characteristics fail to identify elderly ED patients who are likely to be d epressed. Use of a brief SRDS can aid in recognition of depression in this group. (C) 1999 by W.B. Saunders Company.
