OBJECTIVES: To investigate the costs and cost-effectiveness of a short message service (SMS) intervention to prevent the onset of type 2 diabetes mellitus (T2DM) in subjects with impaired glucose tolerance (IGT). METHODS: A Markov model was developed to simulate the cost and effectiveness outcomes of the SMS intervention and usual clinical practice from the health service provider’s perspectiveThe annual transition probabilities between health states were taken from several data sources, including Diabetes Prevention Program and Diabetes Prevention Program Outcome Study. The direct program costs and the two-year SMS intervention costs were evaluated in subjects with IGT. All costs were expressed in year 2011 U.S. dollars. The incremental cost-effectiveness ratio were calculated as cost per T2DM onset prevented, cost per life year gained and cost per quality adjusted life year (QALY) gained. Both base-case scenario and sensitivity analysis were conducted. RESULTS: Within the two-year trial period, the net intervention cost of the SMS group was $42.03 per subject. The SMS intervention managed to reduce 5.05% onset of diabetes, resulting in saving $118.39 per subject over two years. In the lifetime model, the SMS intervention dominated the control by gaining an additional 0.071 QALY and saving $1020.35 per person. The SMS intervention remained dominance in all sensitivity analyses. CONCLUSIONS: This study revealed that the SMS intervention for subjects with IGT had the superiority of lower monetary cost and a considerable improvement in preventing or delaying the T2DM onset.
