Perceptions on handling of opioids: focus COVID-19: A survey among anesthesiologists via the specialist societies DGAI/BDA

Abstract

Background: Opioids are part of the daily routine in anesthesiology and palliative care; however, treatment of dyspnea with opioids is presented heterogeneously in guidelines. This may result in an uncertainty concerning opioid indications and ethical concerns, especially when caring for COVID-19 patients. Objective: We aimed to examine the perception of anesthesiologists concerning the handling of morphine as the reference opioid (subsequently termed M/O) for symptom control within and outside of a palliative care setting, including care for COVID-19 patients. Material and methods: Members of the German Society of Anesthesiology and Intensive Care Medicine (DGAI) and the Professional Association of German Anesthesiologists (BDA) received an anonymized online questionnaire (Survey Monkey®; Momentive Inc., San Mateo, CA, USA) in October 2020, containing questions regarding their perception of symptom management with M/O in general, and in particular concerning COVID-19 patients. Participants were asked to rate their perception within and outside a palliative care setting. Results and discussion: A total of 1365 anesthesiologists participated; 46% women. Most anesthesiologists were 41–60 years old (58%), worked in a hospital setting (78%), in the operating theatre (63%) and in intensive care units (49%). The majority (57%) reported > 20 years of professional experience (52%) and partial involvement in palliative care (57%). Perception of M/O handling was mostly “certain and confident” (88%) and “clearly regulated” (85%) within a palliative care setting but rated substantially lower for outside palliative care (77%/63%). When caring for COVID-19 patients, handling of M/O was even less often rated “certain and confident” (40%) or “clearly regulated” (29%) outside palliative care. Dyspnea (95%/75%), relief of the dying process (84%/51%), agitation (59%/27%) and anxiety/panic (61%/33%) were more frequently rated as general indications for morphine within versus outside palliative care. The majority of anesthesiologists disputed that M/O is given with the intention to hasten death within (87%) and outside (93%) palliative care. Highest difference in route of administration was reported for the subcutaneous administration of M/O within (76%) versus outside (33%) palliative care, followed by the intravenous route (57%/79%), while oral (66/62%) and transdermal (48%/39%) administration were reported to be used comparatively frequently. Most participants (85%) wanted more frequent involvement of palliative care consultation teams but also more team conferences (75%), supervision (72%), and training on opioid management (69%). Conclusion: Anesthesiologists perceived considerable uncertainty in using M/O for nonpalliative care medical settings. Highest uncertainty was seen for the care of patients with COVID-19. The prevalent use of the subcutaneous route for M/O application in palliative care can serve as inspiration for areas outside palliative care as well. Uniform interdisciplinary guidelines for symptom control including dyspnea, education and involvement of a palliative care consultation team should be more considered in the future.
