AIMS: The purpose of this study was to investigate the effectiveness of an inpatient diabetes care education during the first year of internal medicine residency training on inpatient glycemic control.
METHODS: The program was comprised of 1-hr small group teaching per 4-week rotation and twice-a-week morning insulin round by an endocrinologist. Inpatient insulin management guideline leaflet was provided to all internal medicine residents. We retrospectively collected the point-of-care testing for glucose (POCT-glu) data in patients admitted to the general medicine wards and compared the mean of blood glucose (BG) before and after the education program. A total of 134438 POCT-glu values from 7055 patients were analyzed.
RESULTS: After the initiation of the education program, mean BG levels significantly decreased during the first year and were lowest during the second year after education (Mean BG at baseline was 161.38 ± 64.10 mg/dL; 1st year, 159.48 ± 62.53 mg/dL and 2nd year, 155.60 ± 64.94 mg/dL, p-value < 0.0001). The reduction of BG levels was more pronounced in the patients with previously undiagnosed diabetes mellitus than patients with underlying diabetes mellitus. The rates of severe hypoglycemia (defined by BG < 40 mg/dL or 2.2 mmol/L) were not significantly different before and after education (baseline 0.12%, 1st year 0.14%, and 2nd year 0.14%, p-value = 0.632).
CONCLUSIONS: Lack of confidence and inadequate knowledge of insulin treatment in physicians were important barriers to glycemic management. Consistent education in internal medicine residents led to a significant improvement in inpatient glycemic control.
