A randomized controlled trial of telephone-supported care coordination in patients with congestive heart failure

Abstract

An evaluation was undertaken on the effectiveness and efficiency of care coordination as a means of delivering health services to Australian veterans with a diagnosis of congestive heart failure. The veterans participated in a randomized controlled trial of care coordination that was supported by the Department of Veterans' Affairs (DVA). Of 490 veterans who were recruited, 409 were surveyed at baseline (214 in the intervention group and 195 controls). At follow-up, 288 were surveyed (155 intervention and 133 controls). Information on cost of care and quality of life (QOL) was collected before the commencement of coordinated care and at follow-up after 12 months. Cost of care data were obtained from DVA records. Information on QOL was obtained from telephone interviews, using the Short Form (SF-12) Health Survey and the EuroQol Group EQ-5D survey. There were no significant differences in costs of care between the intervention (coordinated care) and control groups of veterans. Nor were there significant differences between the intervention and control groups in QOL measurements with either of the evaluation tools that were used. Because evidence of benefit from coordinated care may be slow to emerge in patients with chronic disease, it would be desirable for future work in this area to include long term, good quality comparative studies on selected veteran populations. Such studies should measure QOL and economic outcomes in addition to clinical indicators.
