Opioid Use Disorder Treatment Disruptions during the COVID-19 Pandemic and Other Disasters: A Scoping Review Addressing Dual Public Health Emergencies

Abstract Background: During public health emergencies, disruptions to social landscapes and amplification of inequities for people with opioid use disorder raise important questions about reducing harms and providing treatment accountability to support this population during disasters including COVID-19. This research aims to a) identify how disasters impact persons with opioid use disorder (OUD) and their access to healthcare, with specific attention to COVID-19, and b) inform ongoing responses to the pandemic and future disaster-mitigation plans related to healthcare disruptions affecting persons with opioid use disorder (PWOUD). Methods: We conducted knowledge synthesis based on a 6-stage scoping review framework methodology. Stakeholder consultation was completed using a Nominal Group Technique with two groups, each composed of including providers in primary, emergency and community-based care. One group (n=7) represented voices from urban services, and the other (n=4) Indigenous contexts allowing for attention to healing the whole person, beyond OAT. Results: 61 scientific journal articles and 72 grey literature resources were included after full-text screening. Stakeholder NGT process revealed three contextual factors affecting system and service accountability for responsive OUD care during disaster-driven disruptions: (1) disasters focus attention on single risks and generalized solutions; (2) data-poor decision-making perpetuates stigma and produces policy inattentive to social determinants of health; and (3) harm reduction and contextually-tailored care prepare a system for future disasters. Conclusion: COVID-19 public health efforts require a coordinated systemic approach to serving PWOUD, based on accountability to patients and support for providers.
