目標：本研究目的在於探討影響醫院購置昂貴之高科技醫療儀器決策的因素，特別是電腦斷層攝影掃描儀(CT)。方法：根據文獻探討和專家意見設計問卷，母體樣本為台南高雄地區之180家醫院。描述性統計用於了解醫院對於購買高科技醫療儀器的一般態度，對數迴歸分析用以決定所選定之因素對醫院購置CT的影響強度。結果：有55家醫院回覆本問卷，其中37份為有效問卷，符合地區醫院(含)以上的要求。描述性數據顯示93％的醫院同意提升醫療品質為購置CT的主要動機，對數迴歸分析卻說明，醫院病床數為唯一影響醫院購置CT的顯著因素(p=0.013)，另一具中度顯著性的因 素為直接的金錢報償(p=0.127)。結論：根據所回覆的有效問卷，配備CT的醫院多為具有較多病床的醫院，此意涵唯有大型醫院有能力購置昂貴的高科技醫療儀器，其目的應為提升醫療品質。

　　　　　Objective: This study investigated factors influencing the acquisition decision among hospitals for new high technology medical units, especially CT scanners. Methods: Hospitals (n=180) in Tainan-Kaoshiung area were chosen as the potential sample source. Literature and experts in health care management were consulted for designing questionnaire. Descriptive statistics was used to summarize the general attitudes toward the acquisition of high technology units at hospitals. Multivariate logistic regression a nalysis was used to determine the strength of association with the acquisition for selected factors. Results: Among 55 respondents, 37 were hospitals meeting survey requirement as regional hospitals or larger hospitals. In the descriptive data, 93% of respondents indicated that the use of CT scanner would elevate the quality of health care at the hospital. However, the logistic regression model showed that the hospital size was the only significant factor (p=0.013) associated with the CT scanner acquisitio n. Although, expected direct monetary return also had moderate significant association with this type of acquisition. Conclusion: In this group of respondents, hospitals equipped with CT scanner were more likely to have larger number of beds. The results suggest that only large hospitals are capable of purchasing high technology with the intention of improving patient care.
