Evaluation of a new care system provided to diabetic patients in the outpatient clinic

Objective Evaluation of metabolic states and chronic complications is essen tial for maintaining a high quality of care for diabetic patients. We have assessed the quality of care in routine outpatient clinics for diabetic sub jects in our university hospital, and compared with those in a newly introd uced standardized clinic to evaluate the new care system. Methods The quality of care was assessed by the chart review in 1995, and c ompared with those from 1996-1997 in the "Diabetes Follow-up Clinic" which is systematically designed for the standardized care, Patients The subjects were recruited among 860 patients who visited the out patient clinic in July and August of 1995 with a diagnosis of diabetes or g lucose intolerance. Six hundred seventy-two patients whose follow-up period had been more than 6 months with clinically diagnosed diabetes were used f or the analysis. Results Laboratory tests such as determination of HbA(1c), and serum levels of lipids and creatinine were performed in more than 90% of the patients i n the routine outpatient clinics, However, ophthalmology referral, 24-hour urine collection for the determination of creatinine clearance and albumin excretion, and electrocardiograms were not well performed and were incomple tely documented (40-60% of the patients within a previous year and 70-80% i n the last 2 years), In the standardized "Diabetes Follow-up Clinic", only four out of 555 diabetic patients failed to collect their 24-hour urine, an d all participants had ankle blood pressure measurements, nerve conduction study, and nylon monofilament tests, etc. Furthermore, more than 95% of the patients had funduscopic examinations by ophthalmologists as well as recor ds of electrocardiogram, Conclusion Introduction of the standardized 'Diabetes Follow-up Clinic" may be one of the choices for increasing the quality of outpatient care and fo r the prevention of chronic diabetic complications.
