Diabetes care in general practice: an approach to audit of process and outcome.

As a chronic condition in which the major adverse outcomes only occur after many years, diabetes poses special problems for continuing medical audit. The feasibility of continuous audit of process and outcome in diabetes care has been tested in four general practices with organized diabetes care in Newcastle upon Tyne. For all patients with previously diagnosed non-insulin dependent diabetes, the data already collected according to published protocols were assembled into a single database. The time and resource costs of this exercise, together with measures of process, complications, risk factors, and metabolic outcomes were analysed. Data were successfully collected at minimal cost where structured records were completed. Recommended processes had been completed in a high percentage of patients, adverse patient outcomes were limited, and metabolic output measures not unsatisfactory. Nevertheless, attention has been directed to areas where care could be improved. Continuing diabetes audit in primary health care is feasible and helpful, and can use the same measures as in the hospital setting.
