Introduction: Continuity of care is one of the core principles of primary care. The importance of interpersonal continuity in treating diabetic patients is unclear.
Aim: To examine the association of interpersonal continuity of care, by the primary care physician, on the process of diabetic care and on health end points including diabetes control, hospital admissions and mortality.
Methods: We conducted a population based cohort study, 23,294 eligible participants were identified in Clalit Health Services Central Region at January 1, 2011 and followed through to December 31, 2012. Multivariate logistic regression models were applied to the data to study simultaneously the independent relationship between low interpersonal continuity, adjusted for background characteristics, and outcomes of care, including hospitalization and mortality.
Results: Achieving clinical targets was more likely in the high interpersonal continuity group HBA1 C OR 1.11 (CI 1.04-1.19), blood pressure OR 1.12 (1.04-1.20), LDL OR 1.14 (1.06-1.22). Patients with high interpersonal continuity had lower odds for mortality OR 0.59 (0.50-0.70). Admissions to hospital were lower in the high interpersonal continuity group, OR 0.82 (0.75-0.90), however when adjusting for background characteristics the difference in OR for hospital admissions became non-significant 0.92 (0.84-1.01).
Conclusion: High interpersonal continuity was associated with improved outcomes of process, and both primary and secondary clinical targets amongst adult patients with diabetes. This study is the first to find an association between interpersonal continuity and mortality amongst adults with diabetes.
