目標：透過醫院高階主管的觀點，建構適合評估醫院資訊系統績效的指標及探討影響系統績效評估的各項因素，並透過實證方式瞭解績效指標與評估因素間的關係。方法：本研究對地區教學以上全部一百二十家醫院的高階主管進行問卷調查，回收率為35%。回收問卷的醫院與母群分佈之x2適合度檢定結果，顯示在醫院等級特性上並無顯著差異，因此研究結果當可代表全體地區教學以上醫院之現況。結果：透過因素分析，歸納出四類績效衡量的指標：使用者滿意度、資訊特性、醫院作業流程，及經營績效等因素。而影響醫院資訊系統績效評估的重要因素，則分別為：環境構面的「政府政策」及「競爭者」等二個因素；資訊科技與廠商構面的「廠商一般特性」、「廠商在醫療業的經驗」、及「硬體設備的功能與成本」等三個因素；以及組織構面的「醫院制度與院長態度」及「醫院對資訊系統的要求與配合」等二個因素。透過迴歸分析，顯示環境與組織構面分別對資訊系統績效的預測具有統計上的意義。以抽取出的的七個因素對資訊系統績效分數的關係整體探討，發現最重要的預測因素是「醫院制度與院長態度」；其次是「政府政策」。結論：影響醫院資訊系統績效的最重要因素是「醫院制度與院長態度」及「政府政策」。(

　　　　　Objectives: To establish a research framework and to identify the critical factors affecting HIS (Hospital Information Systems) performance evaluation. Methods: Data was collected through a self-administered questionnaire survey. The target population was CEOs of 120 regional hospitals and medical centers in Taiwan. The questionnaires were mailed to the CEOs directly and their response rate was 35%. The results of the surveygoodness of fit test indicate that the accreditation classes of the returned sample hospitals have no significant difference from the target population. Results: Seven factors signficantly affected the results of Information Technology (IT) performance evaluation; they are government policy and competitors of the environmental dimension, vendors' characteristics, previous business experience in hospitals, and costs of the IT and vendors' technical ability, hospitals' structure and top managements' attitude, and expectations of the organization on HIS. The regression model indicates that at a 5% level of significance, only the environment and the organizational dimensions are statistically significant to HIS performance. Conclusions:
