ABSTRACT
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%. CONCLUSIONS: 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.
