Evaluating the impact of an international short-term medical mission through diabetic glycemic control

BACKGROUND: This prospective observational study evaluated the impact of a primary care-based, international, short-term medical mission's (STMM) impact on diabetes disease burden as represented through reductions in hemoglobin A1C (HbA1c). METHODS: From November 2016 to May 2017, we tracked the HbA1c's of diabetic individuals in Dajabon, Dominican Republic through care provided by Waves of Health (WOH). Participants were provided counseling, glucose monitoring equipment, a 6-month supply of anti-diabetic medications, and received a 'check-in' phone call at 3 months. HbA1c's were re-measured at 6-month follow up. We hypothesized WOH diabetic care would have a modest impact of reducing mean HbA1c by 0.5%. RESULTS: In total, 75% (n = 76) of 101 participants presented for follow-up care. Mean and median HbA1c decreased from 8.71 (SD 2.0) and 8.5% to 8.36 (SD 2.1) and 7.7%, respectively (P = 0.07). The percentage of individuals with HbA1c
