A Satisfaction Survey on Cancer Pain Management Using a Self-Reporting Pain Assessment Tool

초록

Background: Pain is one of the most common and distressing symptoms in patients with cancer, with a high prevalence of 90%. Appropriate pain assessment is very important in managing cancer pain. Objective: The aims of this study were to (1) evaluate patient satisfaction with pain control therapy using a self-reporting pain assessment tool, (2) explore the usefulness of a self-reporting assessment tool for patients and physicians, and (3) evaluate patient perception of pain management and opioid analgesics. Methods: We enrolled a total of 587 South Korean adult cancer patients hospitalized for five days or more. Pain assessment using a self-reporting pain assessment tool was performed by patients themselves from Day 1 to Day 5. The average pain intensity on a numeric rating scale (NRS) and the frequency of breakthrough pain between Day 1 and Day 5 were recorded with a self-reporting pain assessment tool. We evaluated patient satisfaction with pain control and the usefulness of a self-reporting pain assessment tool for patients and physicians on Day 5. Results: Among the 587 enrolled patients, 551, excluding 36 patients who violated inclusion criteria, were analyzed. The pain satisfaction rate was 79.5%, and only 6.2% of assessed patients had a negative pain management index (PMI). However, symmetry analysis for pain intensity between patient and physician showed low agreement (kappa=0.21). The patients with dissatisfaction for cancer pain control expressed negative attitudes toward using opioid analgesics and misconceptions regarding pain management. The satisfaction for using a self-reporting pain assessment tool was 79.2% in patients and 86.4% in physicians, respectively. Conclusion: The use of a self-reporting pain assessment tool as a communication instrument provides an effective foundation for evaluating pain intensity in cancer pain management. A more individualized approach to patient education about pain management may improve patient outcome.
