Increasing diabetes testing adherence with incentives in rural Northwestern Ontario.

Abstract

Introduction: The health outcomes of rural Canadians have been described as poor and can in some part be related to diabetes mellitus. Despite the high mortality and morbidity rates associated with the disease, compliance with management remains low. Research has shown that a small financial incentive used to modify patient behaviour, can improve outcomes in cardiac disease and exercise adherence. This study aims to evaluate if a small financial incentive awarded to rural Northwestern Ontario patients with diabetes who complete an haemoglobin A1c (HbA1c) test, would result in greater compliance in test completion.

Methods: Patients were recruited through two Northern rural clinics. Participants were divided into two groups: Group A received a financial incentive, whereas Group B received a letter of reminder. HbA1c tests were recorded every 6 months for 2 years and compliance was analysed using a t-test and Chi-square.

Results: One hundred and forty-six participants were recruited with 30 lost to follow-up. Overall, the incentive group completed a statistically significantly higher number of HbA1c tests compared to those in the control group. In addition, it was noted that there was an increase in test adherence for participants that received reminder letters, although not an initially expected outcome of the study.

Conclusion: The results suggest that either a financial incentive or a reminder directed towards rural Canadians could have a benefit in promoting health behaviours to subsequent medical management of diabetes mellitus.
