What Doctors Know About Cancer Pain Management

Systematic Review on Barriers to Access Opioid Analgesics for Cancer Pain Management from the Health Worker Perspective

The increasing incidence of oncological diseases creates a corresponding need for effective cancer pain management (CPM). The lack of access to and availability of opioid analgesics in most countries leads to avoidable suffering. This systematic review aims to identify barriers to accessing opioids, as described in literature that reflects the perspective of health-care workers. A systematic literature search was performed in May 2018 and updated in December 2022, using search terms related to "cancer pain," "opioid analgesics," "access," and "health-care personnel." Medline, Embase, and PsycInfo were searched. Forty-two studies met the inclusion criteria. Principal barriers that have hindered licit access to medical opioids include regulatory, systemic, educational, patient-related, and societal. These barriers are rooted in a lack of adequate education about the importance and significance of appropriate CPM. Barriers were often mutually reinforcing. A interdisciplinary approach is required to overcome them. This research contributes to the important global health issue of unduly limited access to opioid analgesics. It provides interdisciplinary solutions in terms of guidelines to ensure that governments respect, protect, and fulfill the right to the highest attainable standard of health, which includes the relief of severe pain.

Morphine use for cancer pain: A strong analgesic used only at the end of life? A qualitative study on attitudes and perceptions of morphine in patients with advanced cancer and their caregivers

BACKGROUND

The prevalence of undertreated cancer pain remains high. Suboptimal pain control affects quality of life and results in psychological and emotional distress. Barriers to adequate pain control include fear of opioid dependence and its side effects.

AIM

To investigate the attitudes and perceptions of morphine use in cancer pain in advanced cancer patients and their caregivers and to examine the influence of caregivers' attitudes and perceptions on patients' acceptance of morphine.

DESIGN

Qualitative study involving semi-structured individual interviews transcribed verbatim and analyzed thematically.

SETTING/PARTICIPANTS

A total of 18 adult opioid-naïve patients with advanced cancer and 13 caregivers (n = 31) were recruited at a private tertiary hospital via convenience sampling.

RESULTS

Attitudes and perceptions of morphine were influenced by previous experiences. Prevalent themes were similar in both groups, including perceptions that morphine was a strong analgesic that reduced suffering, but associated with end-stage illness and dependence. Most participants were open to future morphine use for comfort and effective pain control. Trust in doctors' recommendations was also an important factor. However, many preferred morphine as a last resort because of concerns about side effects and dependence, and the perception that morphine was only used at the terminal stage. Caregivers' attitudes toward morphine did not affect patients' acceptance of morphine use.

CONCLUSION

Most participants were open to future morphine use despite negative perceptions as they prioritized optimal pain control and reduction of suffering. Focused education programs addressing morphine misperceptions might increase patient and caregiver acceptance of opioid analgesics and improve cancer pain control.
