Health information system transferability evaluation

Abstract

The development of a predictive evaluation model designed to assist a decision maker in estimating the resource costs required to transfer a computerized information system into a specific environment is described. The specific output of the research is a transferability analysis procedure consisting of a systematic approach for the assessment of the areas in which a candidate transfer system is deficient in meeting user requirements. In addition, quantitative resource cost estimates are determined for the resources required to correct particular system deficiencies. An example of the use of the methodology is included. The research methodology utilizes the opinions of expert practitioners in the field of information systems to assist in the development of the model. Validation of the transferability analysis procedure is accomplished at two levels. The resource cost-predictive capabilities of the model are validated by comparing actual site resource requirement data for transferred systems with corresponding estimates provided by the transferability analysis procedure. The usefulness of the transferability analysis procedure is verified by a critical review of the model by potential users of the procedure.
