title: Improvements in diabetic care as measured by HbA1c after a physician education project.
abstract: OBJECTIVE
  To measure the quality of diabetic care as indicated by HbA1c testing frequency and HbA1c values and to demonstrate improvement in care after an appropriate quality improvement intervention.
  
  
  METHODS
  The quality improvement project used computerized claims and laboratory data relating to HbA1c testing among the private practices of nine physicians caring for diabetic Medicare patients. Nine indicators evaluated three main areas: HbA1c testing frequency, HbA1c values, and frequency of office visits. A quality improvement intervention consisting of a physician component and a patient component was implemented.
  
  
  RESULTS
  There were 835 patients and 4,367 visits studied. After the intervention, statistically significant improvements in HbA1c testing frequency and values were noted. Rates of seized opportunities for testing HbA1c improved from 17.7 to 33.9% (P < 0.0001). The percentage of patients with a current HbA1c value improved from 31.3 to 47.6% (P < 0.0001). The median HbA1c values fell from 8.5 to 7.8% (P < 0.006). Patients achieving good or fair control (HbA1c < or = 8%) improved from 43.8 to 56.9% (P = 0.007). The median time between physician visits fell from 70 days to 60 days (P < 0.0001).
  
  
  CONCLUSIONS
  The study revealed that HbA1c testing was underused but that after a quality improvement initiative, a significant increase in testing use could be achieved. The quality improvement initiative also resulted in significant improvements in glycemic control. The techniques and interventions used in this study could be used to intervene in larger populations and practice settings to improve medical care for diabetic patients.
