Abstract
BACKGROUND: The 2-year prospective MOSAIc (Multinational Observational Study assessing Insulin use: understanding the challenges associated with progression of therapy) study is investigating whether patient-, physician-, and health system-related factors affect outcomes in patients with type 2 diabetes (T2D). This baseline subanalysis investigated how aspects of the patient-physician relationship are associated with diabetes-related distress, insulin adherence, and glycemic control. METHODS: Patients with T2D taking insulin for ≥3 months were recruited at primary care and specialty practice sites in 18 countries. Physicians provided usual care. Clinical history and most recent HbA1c values were collected; patients were surveyed regarding their perception of physician interactions, diabetes-related distress level, and insulin adherence. RESULTS: The analysis population comprised 4341 patients. Four (of six) domains showed a significant relationship with total diabetes-related distress (P < 0.01). Poor insulin adherence was associated with greater diabetes-related distress (adjusted odds ratio [aOR] 1.14; 95% confidence interval [CI] 1.06-1.22), higher Discrimination (aOR 1.13; 95% CI 1.02-1.27) and Hurried Communication (aOR 1.35; 95% CI 1.20-1.53) scores, and a lower Explained Results score (aOR 0.86; 95% CI 0.77-0.97). Poor insulin adherence was associated with a 0.43% increase in HbA1c, whereas a 1-unit increase in total diabetes-related distress and Hurried Communication scores was associated with a 0.171% and 0.145% increase in HbA1c, respectively. CONCLUSIONS: Patients distressed about living with T2D, and dissatisfied with aspects of their interactions with physicians, exhibited poor insulin adherence. Perceived physician inattention and lack of engagement (and diabetes-related distress) directly affect insulin adherence and glycemic control.
