Abstract
OBJECTIVE —To assess the long-term effectiveness of a quality improvement program on care provided and patient outcomes in patients
with diabetes.
RESEARCH DESIGN AND METHODS —A nonrandomized trial was performed with 312 patients with type 2 diabetes in the intervention group and 77 patients with
type 2 diabetes in the reference group. The follow-up period was 42 months. The quality improvement program focused on improving
both the provision of diabetes care and the patient outcomes. The program consisted of clinical practice guidelines, postgraduate
education, audit and feedback, templates to register diabetes care, and a recall system. Data on the care provided were abstracted
from medical records. Main outcomes on the provision of care were annual number of patient visits, blood pressure, and HbA 1c and blood lipid levels. Main patient outcomes were blood pressure and HbA 1c and blood lipid levels. Multilevel analysis was used to adjust for dependency between repeated observations within one patient
and for clustering of patients within general practices.
RESULTS —Patients in the intervention group received care far more in accordance with the guidelines than patients in the reference
group. Odds ratios ranged from 2.43 (95% CI 1.01–5.82) for the measurement of urine albumin to 12.08 (4.70–31.01) for the
measurement of blood pressure. No beneficial effect was found on any patient outcome.
CONCLUSIONS —The quality improvement program improved the provision of diabetes care, but this was not accompanied by any effect on patient
outcomes.
