Aim: To evaluate the clinical and health behavioural outcomes of a large sample of participants from the Diabetes Conversation Map™ Program. Design: A matched-case–control study that was performed on a retrospective cohort study. Methods: Participants were 11,053 Clalit Health Services members with type 2 diabetes who enrolled in the Diabetes Conversation Map™ Program between January 2010 - April 2016. The matched-control group was formulated using sequential matching, by matching cases to controls at a ratio of 1:3, based on age, sex, and HbA1c level. The associations between the programme group and annual clinical and health behaviours were assessed between cases and controls at five time points using linear and Poisson regression analyses. Results: The intervention group had significantly lower HbA1c, glucose, and low-density lipoprotein levels and more frequent glucose blood testing each year up to 36 month post-enrolment compared with the matched controls. Other outcomes were significantly different for shorter time periods, including higher high-density lipoprotein and lower triglyceride levels at 6- and 12-month follow-up and lower diastolic blood pressure and greater medication adherence at 6-month follow-up. Conclusions: Enrolment in the programme was associated with improved clinical and health behaviour outcomes for at least 6 months and most outcomes persisted for up to 36 months. Impact: This is the first study to evaluate the Diabetes Conversation Map™ Program with a large sample over long period of time. This nurse-led group intervention evaluation adds to the literature on health outcomes on the lives of patients with type 2 diabetes.
