Are Opioid Infusions Used Inappropriately at End of Life? Results From a Quality/Safety Project.

CONTEXT: Opioid continuous infusions are commonly used for end-of-life (EOL) symptoms in hospital settings. However, prescribing practices vary, and even the recent literature contains conflicting protocols and guidelines for best practice. OBJECTIVES: To determine the prevalence of potentially inappropriate opioid infusion use for EOL comfort care at an academic medical center, and determine if inappropriate use is associated with distress. METHODS: Through literature review and iterative interdisciplinary discussion, we defined three criteria for "potentially inappropriate" infusion use. We conducted a retrospective, observational study of inpatients who died over six months, abstracting demographics, opioid use patterns, survival time, palliative care (PC) involvement, and evidence of patient/caregiver/staff distress from the electronic medical record. RESULTS: We identified 193 decedents who received opioid infusions for EOL comfort care. Forty-four percent received opioid infusions that were classified as "potentially inappropriate." Insufficient use of as-needed intravenous opioid boluses and use of opioid infusions in opioid-naïve patients were the most common problems observed. Potentially inappropriate infusions were associated with more frequent patient (24% vs. 2%; P < 0.001) and staff distress (10% vs. 2%; P = 0.02) and were less common when PC provided medication recommendations (20% vs. 50%; P < 0.001). CONCLUSION: Potentially inappropriate opioid infusions are prevalent at our hospital, an academic medical center with an active PC team and existing contracts for in-hospital hospice care. Furthermore, potentially inappropriate opioid infusions are associated with increased patient and staff distress. We are developing an interdisciplinary intervention to address this safety issue.

Opioid Stewardship: Building on Antibiotic Stewardship Principles.

The opioid stewardship model is born out of the antimicrobial stewardship model, and thus there are many shared characteristics. Both opioid stewardship and antimicrobial stewardship are based on the principle that there is an indication for a particular medication in the right patient at the right time. As antimicrobial stewardship is in a later stage of development, looking at the two in parallel can lead to interesting learning and development opportunities for opioid stewardship. Two requirements of antimicrobial stewardship that need to be applied to opioid stewardship for optimum outcomes are the requirement for dedicated resources, more specifically a trained pharmacist, and a declaration that opioid stewardship is essential for health-system accreditation.
