Philosophical Assumptions Used in Research on Barriers for Effective Cancer Pain Management: A Scoping Review.

Cancer pain is one of the most common symptoms in cancer patients and often has a negative impact on patients' functional status and quality of life. Despite the available guidelines for effective pain management, factors such as barriers to cancer pain management still exist. The lens or philosophical assumptions used to guide cancer pain management research is a crucial but often overlooked component of high-quality research. Therefore, the purpose of this scoping review was to classify and map the available evidence and identify the knowledge gap regarding using a philosophical assumption to address the barriers of pain management among patients with cancer. Absence of clear philosophical assumptions in the qualitative research and generally a theoretical quantitative research may contribute to the slow progress in identifying and addressing barriers to cancer pain management. Therefore, the hermeneutic circle was suggested to address the main barriers of cancer pain management, focusing on the dialectic approach between the participants including researchers, cancer patients, and their family caregivers, health care providers, and policymakers. Understanding and possible solutions of the problem could be obtained through fusion of the horizons; in which the participants past and present horizons emerge. Then the collaborative efforts between the participants may yield effective strategies to overcome cancer pain barriers to improve the quality of cancer pain management.
