In September 2007, the PHQ-2 was added to the nursing interview dataset on 3 cardiac units in a general hospital; this screen was completed as part of routine clinical care. Rates and results of depression screening, reasons for patients not being screened, and results of a nursing satisfaction survey were tabulated, and differences in baseline characteristics between screened and unscreened patients were analyzed via χ<sup>2sup> and independent-samples t tests.
For a 12-month period, 4,783 patients were admitted to the cardiac units; 3,504 (73.3 % ) received PHQ-2 depression screening. Approximately 9 % of screened patients had a PHQ-2 score ≥3 and were approached for further depression evaluation (PHQ-9) by a social worker; 74.1 % of the positive-screen patients had a PHQ-9 score of ≥10, suggestive of major depression. Nurses (n = 66) reported high satisfaction with the screening process, and mean reported PHQ-2 screening time was 1.4 (±1.1) minutes.
Systematic depression screening of cardiac patients using methods outlined by the AHA Prevention Committee is feasible, well-accepted, and does not appear markedly resource-intensive. Future studies should link these methods to an efficient and effective program of depression management in this vulnerable population.
