Knowledge, Attitude, And Barriers Regarding Prescribing Long-Term Opioids Among Taiwan Physicians Treating Officially Registered Patients With Chronic Noncancer Pain

Background:Prescribing opioids for patients with chronic noncancer pain (CNCP) remains controversial. This study surveyed Taiwanese physicians who were clinically treating CNCP outpatients with long-term opioids.Methods:Anonymous questionnaires investigating the clinical practices, opioid knowledge, attitude, and barriers regarding the prescription of long-term opioids were delivered to 66 physicians treating CNCP outpatients who were officially registered and monitored by the Taiwan Food and Drug Administration in 2011.Results:All 66 (100%) physicians responded to the survey, comprising 41 (62%) board-certified pain specialists and 25 (38%) nonpain board-certified physicians. Pain specialists treated a greater number of CNCP outpatients and attended more CNCP training courses than nonpain board-certified physicians (97.6% vs. 56.0%, p < 0.001). Most of pain specialists stated that they were familiar with the Taiwan's narcotic regulations for CNCP patients (92.7% vs. 68.0%, p = 0.015). In addition, pain specialists were less likely to skip or reduce the dosage and duration of opioid prescriptions (22.0% vs. 36.0%, p < 0.001). By contrast, nonpain board-certified physicians had significantly less knowledge and a more negative attitude toward opioid prescription. The major perceived barriers were physician's reluctance to prescribe opioids (78% vs. 92%) and an inadequate knowledge of pain management (73% vs. 84%) among all physicians.Conclusion:Among the Taiwanese physicians treating the officially registered CNCP patients, nonpain board-certified physicians had fewer patients, less knowledge, and an increased negative attitude toward long-term opioid prescriptions. Better education on chronic pain management is needed for improvement of clinical practice.
