Furman RE, et al. - Using a quality improvement (QI) program, researchers sought to improve outcomes of patients with adult type 2 diabetes by reducing HbA_1c undertesting, decreasing the proportion of patients with poor glycemic control, and diminishing mean HbA_1c levels. Before and 2 years after implementing a quality improvement (QI) initiative in an urban academic medical center, 6 years of outpatient electronic health record (EHR) data were analyzed for care gaps. Analysis (January 2010 to May 2018) of 7,798 individuals from Tulane Medical Center (mean age 61 years, 57% female, 62% black, 97% insured) with 136,004 visits recorded target improvements. According to statistical process control charts, 15.5% relative improvement in the patient proportion with HbA_1c > 9% from 13 to 11% following QI interventions and a 2.1% improvement of population mean HbA_1c from 7.4% to 7.2%. Multidisciplinary QI teams utilizing EHR data to design interventions for providers and patients have achieved statistically significant improvements in both the care process and the goals of clinical outcome.
