Patient-reported barriers and outcomes associated with poor glycaemic and blood pressure control in co-morbid diabetes and chronic kidney disease

In patients with comorbid diabetes and chronic kidney disease, the extent to which patient-reported barriers to health-care and patient reported outcomes influence the quality of health care is not well established. This study explored the association between patient-reported barriers to health-care, patient activation, quality of life and diabetes self-care, with attainment of glycaemic and blood pressure (BP) targets.This cross-sectional study recruited adults with diabetes and CKD (eGFR 20 to60 ml/min/1.73m199 patients, mean age 68.7 (SD 9.6), 70.4% male and 90.0% with type 2 diabetes were studied. Poor glycaemic control was associated with increased odds of patient reported "poor family support" (OR 4.90; 95% CI 1.80 to 13.32, p 0.002). Poor BP control was associated with increased odds of patient reported, "not having a good primary care physician" (OR 6.01; 2.42 to 14.95, p 0.001). The number of barriers was not associated with increased odds of poor control (all p 0.05).Specific patient-reported barriers, lack of patient perceived family and primary care physician support, are associated with increased odds of poor glycaemic and blood pressure control respectively. Interventions addressing these barriers may improve treatment target attainment.
