Method: Geriatric patients newly admitted to a large, traditional visiting nurse agency were sampled on a weekly basis over a period of 2 years. The 539 patients ranged in age from 65 to 102 years; 351(65%) were women, and 81 (15%) were nonwhite. The Structured Clinical Interview for DSM-IV Axis I Disorders was used to interview patients and informants. The authors reviewed the results of these interviews plus the patients’ medical charts to generate a best-estimate DSM-IV psychiatric diagnosis.
