• Background and Objective Medical groups have invested billions of dollars in electronic medical records (EMRs), but few studies have examined the cost‐effectiveness of EMR‐based clinical decision support (CDS). This study examined the cost‐effectiveness of EMR‐based CDS for adults with diabetes from the perspective of the health care system. Data Sources/Setting Clinical outcome and cost data from a randomized clinical trial of EMR‐based CDS were used as inputs into a diabetes simulation model. The simulation cohort included 1,092 patients with diabetes with A1c above goal at baseline. Study Design The United Kingdom Prospective Diabetes Study Outcomes Model, a validated simulation model of diabetes, was used to evaluate remaining life years, quality‐adjusted life years (QALYs), and health care costs over patient lifetimes (40‐year time horizon) from the health system perspective. Principal Findings Patients in the intervention group had significantly lowered A1c (0.26 percent, p = .014) relative to patients in the control arm. Intervention costs were $120 (SE = 45) per patient in the first year and $76 (SE = 45) per patient in the following years. In the base case analysis, EMR‐based CDS increased lifetime QALYs by 0.04 (SE = 0.01) and increased lifetime costs by $112 (SE = 660), resulting in an incremental cost‐effectiveness ratio of $3,017 per QALY. The cost‐effectiveness of EMR‐based CDS persisted in one‐way, two‐way, and probabilistic sensitivity analyses. Conclusions Widespread adoption of sophisticated EMR‐based CDS has the potential to modestly improve the quality of care for patients with chronic conditions without substantially increasing costs to the health care system.
