Purpose: This study was designed to describe outcomes of pain management, to identify pain intensity, pain management and barriers to pain management, and to test correlation among the variables in cancer patients who are registered in public health centers. Methods: By using a descriptive survey design, 3 instruments were used to collect data: the Numeric Rating Scale for pain, the Barriers Questionnaire-Korean version, and a one-item self-report tool about patient satisfaction. A sample of 190 patients with cancer was recruited from a public health center. Results: The mean rating for pain during the past 24 hours was mild and the mean score of barriers to pain management was 3.20. Patients were satisfied with pain management but they also had concerns it. A negative correlation was found among pain severity, pain relief and satisfaction of pain management. However, there was not significant correlation between the patient-related barriers to pain management and other variables. Conclusion: These results suggest that the intervention for cancer patients should focus not only on patient-related barriers to pain management, but also address health-care system related barriers.
