Purpose: Pain is one of the most common and devastating symptoms in cancer patients, and misunderstandings on the patient's part can cause major obstacles in pain management.
Method: We evaluated factors associated with patient's high barrier score to managing cancer-associated pain by having 201 patients complete the Korean Barriers Questionnaire II, the Brief Pain Inventory--Korean, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30, and the Korean Beck Depression Inventory. The Pain Management Index (PMI) was also assessed.
Results: The patients were from nine oncology clinics in university hospitals and a veterans' hospital in South Korea. The median pain score (0-10 scale) was 4, with a median percentage of pain improvement during the last 24 h of 70 %. A total of 150 patients (75 %) received strong opioids, and 177 (88 %) achieved adequate analgesia (positive PMI). Mean scores ± SD for the Barriers Questionnaire II ranged from 1.5 ± 1 to 2.8 ± 1.1, with the harmful effects subscale the highest. In the multiple regression model, depression was significantly associated with total barrier score to pain management (p < 0.0001). Pain reduction was significantly associated with the fatalism subscale.
Conclusions: Depression was associated with high barrier score in patients with cancer pain. Management of cancer pain should include screening for depression, and management of depression could reduce patient-reported barriers to pain management.
