Objectives:This study presents the information system for Pusan National University Hospital (PNUH), evaluates its perfor-mance qualitatively, and conducts economic analysis.
Methods: Information system for PNUH was designed by component-based development and developed by internet technologies. Order Communication System, Electronic Medical Record, and Clinical Decision Support System were newly developed. The performance of the hospital information system was qualita-tively evaluated based on the performance reference model in order to identify problem areas for the old system. The Infor-mation Economics approach was used to analyze the economic feasibility of hospital information system in order to account for the intangible benefits.
Results: Average performance scores were 3.16 for input layer, 3.35 for process layer, and 3.57 for business layer. In addition, the cumulative benefit to cost ratio was 0.50 in 2011, 1.73 in 2012, 1.76 in 2013, 1.71 in 2014, and 1.71 in 2015. The B/C ratios steadily increase as value items are added.
Conslusions:While overall performance scores were reasonably high, doctors were less satisfied with the system, perhaps due to the weak clinical function in the systems. The information economics analysis demonstrated the economic profitability of the information systems if all intangible benefits were included. The second qualitative evaluation survey and economic analysis were proposed to evaluate the changes in per-formance of the new system.
