The Restoring Health Program, a multi-disciplinary model of care for patients with chronic lung diseases, heart failure, and diabetes, was established to improve the quality of life and function for patients with these target chronic diseases, while reducing their disproportionately high demand on acute health care services. Acute health care utilization at St Vincent's Hospital Melbourne for all patients recruited between February 2003 and June 2005 (n = 351) was analyzed using within-subjects paired sample t-tests to compare the 6 months of pre-recruitment with 6 months of post-recruitment. Analysis showed statistically significant decreases in emergency department presentations (P < 0.001), hospital admissions (P < 0.001), and length of stay (P < 0.001). This article describes the current model of care, the program's enablers, and its impact on health service demand after the first 4 years of implementation.
