RESUMO
BACKGROUND: The United States has been grappling with the opioid epidemic, which has resulted in over 75,000 opioid-related deaths between April 2020 and 2021. Evidence-based pharmaceutical interventions (buprenorphine, methadone, and naltrexone) are available to reduce opioid-related overdoses and deaths. However, adoption of these medications for opioid use disorder has been stifled due to individual- and system-level barriers. External facilitation is an evidence-based implementation intervention that has been used to increase access to medication for opioid use disorder (MOUD), but the implementation costs of external facilitation have not been assessed. We sought to measure the facility-level direct costs of implementing an external facilitation intervention for MOUD to provide decision makers with estimates of the resources needed to implement this evidence-based program. METHODS: We performed a cost analysis of the pre-implementation and implementation phases, including an itemization of external facilitation team and local site labor costs. We used labor estimates from the Bureau of Labor and Statistics, and sensitivity analyses were performed using labor estimates from the Veterans Health Administration (VHA) Financial Management System general ledger data. RESULTS: The average total costs for implementing an external facilitation intervention for MOUD per site was $18,847 (SD 6717) and ranged between $11,320 and $31,592. This translates to approximately $48 per patient with OUD. Sites with more encounters and participants with higher salaries in attendance had higher costs. This was driven mostly by the labor involved in planning and implementation activities. The average total cost of the pre-implementation and implementation activities were $1031 and $17,816 per site, respectively. In the sensitivity analysis, costs for VHA were higher than BLS estimates likely due to higher wages. CONCLUSIONS: Implementing external facilitation to increase MOUD prescribing may be affordable depending on the payer's budget constraints. Our study reported that there were variations in the time invested at each phase of implementation and the number and type of participants involved with implementing an external facilitation intervention. Participant composition played an important role in total implementation costs, and decision makers will need to identify the most efficient and optimal number of stakeholders to involve in their implementation plans.
RESUMO
BACKGROUND: The Veterans Health Administration (VHA) is invested in expanding access to medication treatment for opioid use disorder (MOUD) to save lives. Access varies across VHA facilities and, thus, requires implementation strategies to promote system-wide adoption of MOUD. We conducted a 12-month study employing external facilitation that targeted MOUD treatment among low-adopting VHA facilities. In this study, we sought to evaluate the patterns of perceived barriers over 1 year of external implementation facilitation using the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework. METHODS: We randomly selected eight VHA facilities from the bottom quartile of the proportion of Veterans with an OUD diagnosis receiving MOUD (< 21%). The 1-year external implementation intervention included developmental evaluation to tailor the facilitation, an on-site visit, and monthly facilitation calls. Facilitators recorded detailed notes for each call on a structured template. Qualitative data was analyzed by coding and mapping barriers to the constructs in the i-PARIHS framework (Innovation, Recipients, Context). We identified emerging themes within each construct by month. RESULTS: Barriers related to the Innovation, such as provider perception of the need for MOUD in their setting, were minimal throughout the 12-month study. Barriers related to Recipients were predominant and fluctuated over time. Recipient barriers were common during the initial months when providers did not have the training and waivers necessary to prescribe MOUD. Once additional providers (Recipients) were trained and waivered to prescribe MOUD, Recipient barriers dropped and then resurfaced as the facilities worked to expand MOUD prescribing to other clinics. Context barriers, such as restrictions on which clinics could prescribe MOUD and fragmented communication across clinics regarding the management of patients receiving MOUD, emerged more prominently in the middle of the study. CONCLUSIONS: VHA facilities participating in 12-month external facilitation interventions experienced fluctuations in barriers to MOUD prescribing with contextual barriers emerging after a facilitated reduction in recipient- level barriers. Adoption of MOUD prescribing in low-adopting VHA facilities requires continual reassessment, monitoring, and readjustment of implementation strategies over time to meet challenges. Although i-PARIHS was useful in categorizing most barriers, the lack of conceptual clarity was a concern for some constructs.
