Web of Science與醫院學術成就評比－－以中臺灣三家醫學中心為例

Use of WoS Database for Evaluating Academic Achievement in Three Medical Centers in Central Taiwan

目標：本研究探討以ISI（Institute of Scientific Information）公司出版之WoS（Web of Science）網路資料庫，評比醫學中心學術成就可能引發之問題。方法：根據台灣地域上的相關性與醫院評鑑結果，我們從WoS資料庫搜尋中台灣三家醫學中心（中國醫藥大學附設醫院、彰化基督教醫院、與台中榮民總醫院）於2002年發表之學術論文，就其論文篇數、刊載論文之期刊影響因子（Impact Factor; IF）、h-指標、和論文平均被引用數進行分析。結果：中國醫藥大學附設醫院在論文篇數及h指標部分表現較優，台中榮民總醫院則在平均論文期刊影響因子部分表現較優。若考慮論文平均被引用數，台中榮民總醫院居首，彰化基督教醫院居末，但其結果不具統計顯著性（p=0.324）。結論：以WoS資料庫指標來評比醫學中心的學術研究水準，可能會因指標的特性不同而產生不同的排序。本文建議須視評鑑的目的為何，才能決定要使用何種或多種不同權重的指標，來呈現醫學中心的學術成就，如此才會讓受評醫院接受評比的結果。

Objectives: To explore the potential pitfalls of using the database of Web of Science (WoS) (issued by Institute of Scientific Information) for evaluating academic achievement in medical centers. Methods: Based on the results of the accreditation of medical centers in central Taiwan, we selected Chinese Medical College Hospital (CMCH), Changhua Christian Hospital (CCH) and Taichung Veterans General Hospital (TCVGH) in this study. Using WoS database in 2002, the total number of the published articles, impact factors of the journals, h-index and the average citation number were analyzed. Results: The results of comparison of academic achievement among three medical centers were different, pending on which indicators were used. CMCH takes the lead in the categories of the total number of the published articles and the h-index. TCVGH has the highest average impact factors of the journals on which their articles were published. Although the rank of average citation number is TCVGH > CMCH > CCH, the difference was not statistically significant (p=0.324). Conclusions: Using the database of WoS for evaluating the academic achievement in medical centers needs special consideration. Due to its own intrinsic characteristics, each indicator from the database of WoS reflects different status of academic achievement. Careful selection of appropriate weighing indicator(s) is recommended during hospital accreditation process.
