Evaluating eHealth: How to Make Evaluation More Methodologically Robust
نویسندگان
چکیده
eHealth—the organisation and delivery of health services and information using information technology (IT) systems—is playing an increasingly important role in shaping health care systems. However, as Catwell and Sheikh described in the first article in this series [1], IT systems can introduce harms as well as benefits. Catwell and Sheikh argued for a general scheme of evaluation starting with careful specification of need and pre-implementation testing in their article. This philosophy of pre-implementation testing resonates strongly with the UK Medical Research Council (MRC) framework for evaluation of complex interventions [2], the tenets of safety science (which endorses the use of analytic procedures to predict the failure rate of a system still in the design phase), and established principles in the IT field where ‘‘alpha testing’’ is routine. But how should IT systems be evaluated as they are rolled out following pre-implementation testing? This is the aspect of eHealth we will consider in this essay.
