Saaddine JB, Engelgau MM, Beckles GL, Gregg EW, Thompson TJ, Narayan KMV: A diabetes report card for the United States: quality of care in the 1990s. Ann Intern Med 136:565574, 2002
Objective. To assess the quality of diabetes care in the United States by applying accountability and quality improvement measures proposed by the Diabetes Quality Improvement Project (DQIP).
Design. A cross-sectional analysis of data obtained from two large nationwide studies.
Subjects and methods. Data were obtained from the Third National Health and Nutrition Examination Survey (NHANES III), conducted from 1988 to 1994, and from the Behavioral Risk Factors Surveillance System (BRFSS) for 1995. The NHANES III population was a nationwide sample of non-institutionalized U.S. citizens with deliberate oversampling of non-Hispanic blacks, Mexican Americans, and the elderly. It included an interview, a physical examination, and laboratory studies including measurement of hemoglobin A1c (A1C), cholesterol levels, and triglycerides. The BRFSS 1995 sample was obtained using a random digit telephone survey method. Specific questions on laboratory testing, cholesterol levels, and eye and foot examinations were included in the BRFSS survey for all subjects with self-reported diabetes. This study included 1,026 subjects from NHANES III and 3,059 subjects from BRFSS, aged 1875 years, with self-reported diabetes. Laboratory data and clinical management data were provided by NHANES III and BRFSS, respectively.
Results. A total of 28.8% of subjects reported having had an A1C measurement performed within 1 year of the study, and 85.3% reported having cholesterol levels measured within 2 years. A total of 63.3% of diabetic subjects reported having had a dilated eye examination within the past year, and 54.8% reported having had a foot examination in the same time period. Information on assessment of nephropathy was not obtained.
Elderly subjects were more likely than younger subjects
