Routine PHQ-9 depression screening in home health care: depression, prevalence, clinical and treatment characteristics and screening implementation.

This study aimed to examine: the prevalence and correlates of depression among adults age 65 and over on admission to diverse home health care programs; nurse compliance with routine screening using the PHQ-9; and concordance between the number of depressed individuals identified by the PHQ-9 and Medicare-mandated nursing assessment following targeted nurse training in identifying depression among the elderly using a standard diagnostic screen. Data are drawn from routine screening of 9,178 patients (a 77% screening compliance rate). Of all patients screened, 782 (8.5%) met criteria for probable major depression and 148 (1.6%) for mild depression. Concordance between nurse identified depression via PHQ-9 and OASIS depression assessment improved over that reported in previous studies. Findings suggest that the use of a routine screening tool for depression can be implemented with minimal in-house training and improves detection of depression among older adults with significant physical and functional impairment.
