背景：疼痛紀錄是醫護人員提供疼痛照護重要依據，若疼痛紀錄未整合或不完整會影響病人安全，而運用資訊科技有助於醫護人員之間溝通及提升照護品質。
目的：評值護理人員使用疼痛照護系統的成效。
方法：採用問卷調查法，以資訊系統成功模式之系統品質、資訊品質、服務品質、使用意圖、使用滿意度和淨效益等六構面來設計系統評值問卷。於系統導入三個月後收集中部某醫學中心282位護理人員意見，使用描述性和推論性統計方法分析研究資料。
結果：疼痛照護系統評值問卷六構面中，以資訊品質分數4.71分為最高，使用意圖及使用滿意度二個構面與淨效益的相關性最高。使用滿意度對系統淨效益的預測力最高，解釋力約81.2 %。
結論：疼痛照護系統提供完整及正確的疼痛資訊品質，是影響護理人員對系統的使用意圖及滿意度重要因素。經由資訊系統成功模式進行評量結果，顯示出疼痛照護系統是一個能提供正確資訊，且高使用意願及高滿意度的良好資訊系統。

Background: Pain records provide important data to medical teams to guide their provision of pain management interventions. Incomplete records and records that do not integrate pain data will affect patient safety. Use of information technology helps facilitate communication within the medical team and improve quality of care.
Purpose: This study was designed to evaluate the effectiveness of a pain management information system. Methods: The questionnaire survey method was employed in this study. The system-evaluation questionnaire was designed based on the six dimensions of the information system success model (ISSM), including system quality, information quality, service quality, intention to use, user satisfaction, and net benefits. Three months after the pain management system was implemented, the opinions of 282 nurses from a medical center in central Taiwan were collected. Research data were analyzed using descriptive and inferential statistical methods.
Results: Of the six dimensions, “information quality” received the highest average score (4.71). The two dimensions of “intention to use” and “user satisfaction” had the highest correlation with “net benefits”. “User satisfaction” was found to have the highest predictive power for the “net benefits” of the system, with an explanatory power of about 81.2%.
Conclusion: The pain management system considered in this study was shown to provide complete and accurate pain management information, which is an important factor affecting nurses’ intention to use and satisfaction. The evaluation results based on the ISSM show the pain management system to be a good information system that generates accurate information and has a high intention-to-use rate and high rate of user satisfaction.
