SiMCare Diabetes is an interactive online simulation tool that uses patient case scenarios to train clinicians in evidence-based diabetes care. Randomized controlled trials show it improves diabetes care measures and outcomes. It teaches clinicians to accurately diagnose and manage diabetes, hypertension, dyslipidemia and obesity through hands-on practice adjusting medications and recommending testing and referrals. Published results found clinicians using SiMCare Diabetes had higher satisfaction, knowledge, ability to achieve care goals, and confidence in insulin use compared to a control group. Their real patients also saw improved glycemic control, lower costs, and less risky prescribing after clinicians used the simulation tool.
