| Summary: | Diabetes is among the most prevalent chronic conditions in Canada. It is characterized by a body's inability to produce or efficiently use insulin. Diabetes can be effectively managed, often with the support of a primary care provider. Unfortunately, the high turnover rate of family physicians (FPs) in Newfoundland and Labrador (NL) threatens continuity of care, potentially contributing to poorer health outcomes for people with diabetes. This study examines the relationship between FP turnover and glycemic control, hospitalization, and mortality among patients with diabetes in NL. It was hypothesized that FP turnover would be related to the three outcomes of interest. Specifically, it was expected that high turnover rates would be associated with poorer glycemic control and increased risk of hospitalization and mortality. To examine these hypotheses, a cross-sectional analysis of adults (20+ years) with diabetes in NL between 2011 and 2015 was performed. Secondary data sources were linked, including the provincial Chronic Disease Registry and the Physician and Medical Practice Database. Multivariate binary logistic regression was used to examine the relationship between FP turnover, glycemic control, hospitalization, and mortality while controlling for important covariates. The analyses provided mixed support for the hypotheses. FP turnover was found to be associated with glycemic control and hospitalization but not mortality. Further, FP turnover was associated with an increased risk of hospitalization, but the direction of the relationship between turnover and glycemic control was inconsistent with the hypothesis. Findings from this study also suggest that regions with no FPs performed similarly to regions with low turnover on the outcomes of glycemic control and hospitalization. These findings may have implications for the delivery of primary care in NL. Future studies should examine primary care models in regions with no FPs and consider whether these models could be more widely applied in NL for chronic ... |
