Overcoming barriers in cancer pain management.

Pain is a devastating symptom of cancer that affects the quality of life of patients, families, and caregivers. It is a multidimensional symptom that includes physical, psychosocial, emotional, and spiritual components. Despite the development of novel analgesics and updated pain guidelines, cancer pain remains undermanaged, and some patients with moderate to severe pain do not receive adequate pain treatment. Inadequate pain management can be attributed to barriers related to health care professionals, patients, and the health care system. Common professional-related barriers include poor pain assessment, lack of knowledge and skill, and the reluctance of physicians to prescribe opioids. Patient-related barriers include cognitive factors, affective factors, and adherence to analgesic regimens. System-related barriers such as limits on access to opioids and the availability of pain and palliative care specialists present additional challenges, particularly in resource-poor regions. Given the multidimensional nature of cancer pain and the multifaceted barriers involved, effective pain control mandates multidisciplinary interventions from interprofessional teams. Educational interventions for patients and health care professionals may improve the success of pain management.
