New Integrated Information System for Pusan National University Hospital

Abstract

ObjectivesThis study presents the information system for Pusan National University Hospital (PNUH), evaluates its performance qualitatively, and conducts economic analysis.MethodsInformation 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 qualitatively evaluated based on the performance reference model in order to identify problem areas for the old system. The Information Economics approach was used to analyze the economic feasibility of hospital information system in order to account for the intangible benefits.ResultsAverage 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.ConclusionsWhile 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 performance of the new system.

Technical Requirements Framework of Hospital Information Systems: Design and Evaluation

“…System response time is a major technical challenge of the HIS [28,62]. The dissatisfaction with this domain highlighted in numerous studies was reported as an obstacle to applying EHRs and the main reason for their abandonment by users [62][63][64].…”

“…System response time is a major technical challenge of the HIS [28,62]. The dissatisfaction with this domain highlighted in numerous studies was reported as an obstacle to applying EHRs and the main reason for their abandonment by users [62][63][64]. Organizations that heavily depend on computerized systems to deliver patient care require downtime as low as 0% and business continuity procedures to ensure safety and patient care continuity [65].…”

Measuring the Immeasurable? the Intangible Benefits of Digital Information

“…Input/Output of measurement process Royer and Wolfgang [40] I = intangible benefits in the financial, security/risk mgmt., supporting processes and business processes, O = measurements Grembergen and Amelinckx [13] I = survey(s) with questions in the area of customer orientation, business contribution, customer orientation, operational excellence, and future orientation O = measurements KPI is used as one way of transforming the intangible benefits to tangible [12,24], see Table 7. The starting point for both these articles is to understand the KPI for the desired output.…”
