How Is the Economic Value of Infection Prevention and Control Measured? A Methodological Scoping Review

A methodological scoping review of how healthcare infection prevention and control interventions are economically evaluated. The review will map how studies define the decision problem, identify, measure and value resources, estimate outcomes, model transmission and uncertainty, calculate financial and health-economic results, and interpret transferability. It will distinguish formal economic evaluations from costing studies, budget-impact analyses and ROI/business cases, and will develop a provisional modular reporting framework.
