Results of the study provide insights into the differences in trends between participants and nonparticipants in DSMT. People with diabetes who had DSMT encounters provided by diabetes educators in accredited/recognized programs are likely to show lower cost patterns when compared with a control group of people with diabetes without DSMT encounters. People with diabetes who have multiple episodes of DSMT are more likely to receive care in accordance with recommended guidelines and to comply with diabetes-related prescription regimens, resulting in lower costs and utilization trends. Conclusions and Policy Implications The collaboration between diabetes educators and patients continues to demonstrate positive clinical quality outcomes and cost savings. This analysis shows that repeated DSMT encounters over time result in a dose-response effect on positive outcomes.
