Randomized trial of quality improvement intervention to improve diabetes care in primary care settings.
ABSTRACT To assess the impact of a quality improvement (QI) intervention on the quality of diabetes care at primary care clinics.
Twelve primary care medical practices were matched by size and location and randomized to intervention or control conditions. Intervention clinic staff were trained in a seven-step QI change process to improve diabetes care. Surveys and medical record reviews of 754 patients, surveys of 329 clinic staff, interviews with clinic leaders, and analysis of training session videotapes evaluated compliance with and impact of the intervention. Mixed-model nested analyses compared differences in the quality of diabetes care before and after intervention.
All intervention clinics completed at least six steps of the seven-step QI change process in an 18-month period and, compared with control clinics, had broader staff participation in QI activities (P = 0.04), used patient registries more often (P = 0.03), and had better test rates for HbA(1c) (A1C), LDL, and blood pressure (P = 0.02). Other processes of diabetes care were unchanged. The intervention did not improve A1C (P = 0.54), LDL (P = 0.46), or blood pressure (P = 0.69) levels or a composite of these outcomes (P = 0.35).
This QI change process was successfully implemented but failed to improve A1C, LDL, or blood pressure levels. Data suggest that to be successful, such a QI change process should direct more attention to specific clinical actions, such as drug intensification and patient activation.

ABSTRACT: To report provider adherence to standards of care for adults with type 2 diabetes before and after a quality improvement (QI) intervention. Pre- and post intervention data were abstracted from 50 medical records of patients with type 2 diabetes in a small primary care practice. There was a significant increase in the rates of foot and urine microalbumin screenings, documentation for dilated eye exams were not statistically significant. These findings demonstrated the effectiveness of using simple practice aids to reinforce adherence to the standards of care in diabetes. The failure to see a corresponding improvement in glycemic and blood pressure control is consistent with prior research and the need for more research in this area remain critical. Ethnic minorities are more likely to have worse control of their diabetes and more likely to receive all their care in the primary care setting, QI interventions targeting primary care providers have the potential to reduce disparities in diabetes care. Future research to determine whether cultural tailoring of diabetes QI interventions will produce additional benefits above those of generic diabetes QI interventions are needed.Journal of the American Association of Nurse Practitioners. 10/2013; 25(10):527-34.

ABSTRACT: Printed educational materials for clinician education are one of the most commonly used approaches for quality improvement. The objective of this pragmatic cluster randomized trial was to evaluate the effectiveness of an educational toolkit focusing on cardiovascular disease screening and risk reduction in people with diabetes. All 933,789 people aged ≥40 years with diagnosed diabetes in Ontario, Canada were studied using population-level administrative databases, with additional clinical outcome data collected from a random sample of 1,592 high risk patients. Family practices were randomly assigned to receive the educational toolkit in June 2009 (intervention group) or May 2010 (control group). The primary outcome in the administrative data study, death or non-fatal myocardial infarction, occurred in 11,736 (2.5%) patients in the intervention group and 11,536 (2.5%) in the control group (p = 0.77). The primary outcome in the clinical data study, use of a statin, occurred in 700 (88.1%) patients in the intervention group and 725 (90.1%) in the control group (p = 0.26). Pre-specified secondary outcomes, including other clinical events, processes of care, and measures of risk factor control, were also not improved by the intervention. A limitation is the high baseline rate of statin prescribing in this population. The educational toolkit did not improve quality of care or cardiovascular outcomes in a population with diabetes. Despite being relatively easy and inexpensive to implement, printed educational materials were not effective. The study highlights the need for a rigorous and scientifically based approach to the development, dissemination, and evaluation of quality improvement interventions. http://www.ClinicalTrials.gov NCT01411865 and NCT01026688 Please see later in the article for the Editors' Summary.PLoS Medicine 02/2014; 11(2):e1001588. · 14.00 Impact Factor
