title: Double-disease management or one care manager for two chronic conditions: pilot feasibility study of nurse telephonic disease management for depression and congestive heart failure.
abstract: This study assessed the feasibility of a telephonic nurse double-disease management program (DDMP) for patients with depression and congestive heart failure. Thirty-five patients with depression and congestive heart failure were entered into a novel DDMP modeled after Wagner's chronic illness care model and implemented as part of a 13-month Breakthrough Series Collaborative administered by the Institute of Healthcare Improvement. Twenty-four patients remained in the program long enough to complete at least one follow-up assessment (ie, 6 weeks or longer). Patients were entered into the program based on depression severity scores from either the interactive voice response (IVR) version of the Hospital Anxiety and Depression Scale (HADS) or the self-administered (or telephonic) Patient Health Questionnaire (PHQ). Because use of the IVR version of the HADS was eliminated after several weeks into the program (because of poor patient acceptance), 19 patients had both entry and follow-up scores on the same instrument (PHQ). Depression "response" was defined as a 50% improvement in PHQ score. Mixed models regression was used to test the statistical significance of change in PHQ scores over time. Patient and clinician reports were obtained to evaluate program acceptability and satisfaction. Eighty-two percent of patients (n = 11) with Major Depressive Disorder (MDD) responded, and 75% of patients (n = 8) with "other depression" (PHQ score < 10) responded. Mean change in PHQ scores for the sample as a whole improved significantly over the 24 weeks of the program (p < 0.0003), as well as for those with major depression and other depression considered separately (p < 0.01 for both). In some patients who refused medication, depression seemed to respond to self-management support interventions of the care manager. Based on patient acceptance and clinicians' reports, the program appeared feasible and possibly effective. DDMP appears feasible and possibly effective. Future clinical trials are warranted.
