Cost-Benefit Analysis and Evaluation of Operational Impact of Medical Information Systems: Cost-Benefit Analysis in a Computer-Based Hospital Information System

摘要

A unique cost benefit analysis model is developed for a Hospital Information System which is being used in an ancillary (service) department. The objective of this analysis approach is to determine the financial impact of a proposed hospital/clinical information system at the department and hospital level. Based on industrial engineering techniques and compartmental analysis, the mathematical model is applied to the Dallas County Hospital District Radiology Department considering the procedure costs before and after installation of the Parkland On-Line Information System (POIS). Using the concepts of an “average procedure” and Standard Patient Load, preliminary results from the model indicated the unit procedure cost would drop from $8.66 to $8.63 each. Further savings were generated because of a 3% decrease in volume due to elimination of duplicate procedures. These combined effects give a preliminary calculated annualized savings of $70,887.
