Objectives: A cancer pain clinic (CPC) service is a thorough, comprehensive consultation service for patients with uncontrolled cancer pain. The aim of this study was to determine the success of a new CPC service with enrollment via electronic health record-based automatic screening at 1 cancer center in Korea.
Study design: A case-control study and a satisfaction survey.
Methods: The intervention group (n = 158) was enrolled in the CPC service, whereas the control group (n = 158), which was matched using propensity scores, did not participate in the service. The pain scores of participants were compared using an independent t test. Thirty-nine patients and 20 physicians completed a self-administered survey on instructions for pain-relief medications, effective usage of long-acting and short-acting opioids, perceptions of or barriers to CPC services, knowledge of opioid use, and overall satisfaction.
Results: Although the baseline pain score of the intervention group was significantly higher than that of the control group (P = .013), the difference in the decrease of pain between the groups was significant at days 1 (P = .001) and 2 (P = .039). Although the difference in pain scores disappeared on day 3, total pain score was significantly lower in the intervention group than in the control group (P = .012). When comparing pain relief events (<4 points on a 0-10 numeric rating scale that measured pain daily), the intervention group experienced more relief events than did controls (P = .017). Patients were satisfied with their physicians giving clear instructions and considering their opinions about pain-relief medications. The oncology residents expressed satisfaction with the management of patients with opioid-naïve or intractable pain.
Conclusions: The new CPC service seems to provide effective pain relief and users seem to be highly satisfied with it. These results support the importance of an integrated and specialized approach to cancer-related pain management.
