Abstract

Benchmarking depressive symptoms within Cardiac Rehabilitation(CR) identifies vulnerable individuals who are at elevated risk of the negative health consequences of elevated depressive symptoms. Depression was benchmarked in patients in Phase II of the University of Vermont Medical Center CR program across clinical and demographic variables utilizing the Geriatric Depression Scale-Short Form (GDS-SF) and Patient Health Questionnaire (PHQ-9). Among those with full (9+) session count, mean depression scores were lower than those who did not complete at least 9 sessions (PHQ-9=4.21+-5.47, GDS-SF=3.02+-2.82 vs PHQ-9=5.32+-5.47, p<.01 GDS-SF=3.60+-2.82 p<.01). Prevalence of mild or worse levels of depression was 31.4% and 20.1% on the PHQ-9 and GDS-SF, respectively, at entry. The PHQ-9 identified significantly more patients with at least mild symptoms (p<.01). Patients with higher symptoms on the PHQ-9 at entry were younger (Chi2 (4)=20.4, p<.01, more likely to be female (Chi2 (4)=20.6, p<.01), attended fewer sessions (Chi2 (8)=36.6, p<.01), and had lower VO2 (Chi2 (12)=22.8, p=.03). Of those with at least mild symptoms, most decreased depression severity by at least one level by exit (PHQ-9=73.4%, GDS-SF=72.0%). Improvement in symptoms did not differ by screener, either within the whole population, or within those who are 65+ (p>.05).
