Objectives: To assess the validity of self-reported preventive services, medications, and diagnoses among persons with diabetes. Methods: A behavioral risk factor surveillance system telephone survey (BRFSS) was conducted among patients with diagnosed diabetes in a fee-for-service practice and a community health center (N=200). Self-reported data were compared to medical record information for seven preventive services, aspirin and lipid lowering medications. Preventive services included blood pressure screening, foot and retinal examinations, HbA1c testing, and influenza and pneumococcal immunizations. Results: The sensitivity of self-reported preventive services was >80%. The specificity of preventive services was lower (<60%), particularly for retinal exams (19%). The sensitivity and specificity of self-reported regular aspirin use and lipid lowering medication was >60% and >70%, respectively. Only 24% of respondents knew their last HbA1c value, which was weakly correlated to the last HbA1c value documented in the medical record (coefficient .43). Conclusions: Self-reported information regarding preventive services, medications and other conditions among persons with diabetes is fairly accurate for population surveillance. However, self-reported retinal examinations and HbA1c values may not be accurate.
Learning Objectives: 1. Describe BRFSS survey questions used to assess care for persons with diabetes. 2. Describe the validity of BRFSS diabetes care questions compared to documentation of information in the medical record. 3. Identify possible factors associated with variation between self-reported information compared to information from the medical record.
