The effectiveness of coordinated care for people with chronic respiratory disease

Abstract

Objectives: To evaluate the effectiveness of coordinated care for chronic respiratory disease. Design and setting: Community-based geographical control study, in western (intervention) and northern (comparison) metropolitan Adelaide (SA). Participants: 377 adults (223 intervention; 154 comparison) with chronic obstructive pulmonary disease, asthma or other chronic respiratory condition, July 1997 to December 1999. Intervention: Coordinated care (includes care coordinator, care guidelines, service coordinator and care mentor). Main outcome measures: Hospital admissions (any, unplanned and respiratory), functionality (activities of daily living) and quality of life (SF-36 and Dartmouth COOP). Results: At entry to the study, intervention and comparison subjects were dissimilar. The intervention group was 10 years older (P < 0.001), less likely to smoke (P = 0.014), had higher rates of hospitalisation in the previous 12 months (P < 0.001) and had worse self-reported quality of life (SF-36 physical component summary score [P < 0.001] and four of nine COOP domains [P = 0.002–0.013]). After adjustment for relevant baseline characteristics, coordinated care was not associated with any difference in hospitalisation, but was associated with some improvements in quality of life (SF-36 mental component summary score [P = 0.023] and three of nine COOP domains [P = 0.008–0.031]) compared with the comparison group. Conclusions: Coordinated care given to patients with chronic respiratory disease did not affect hospitalisation, but it was associated with an improvement in some quality-of-life measures.
