Identifying Implementation Determinants and Strategies for Long-Acting Injectable Cabotegravir-Rilpivirine in People With HIV Who Are Virally Unsuppressed

J Acquir Immune Defic Syndr. 2024 Jul 1;96(3):280-289. doi: 10.1097/QAI.0000000000003421.

Abstract

Background: Early evidence suggests long-acting injectable cabotegravir and rilpivirine (LA-CAB/RPV) may be beneficial for people with HIV (PWH) who are unable to attain viral suppression (VS) on oral therapy. Limited guidance exists on implementation strategies for this population.

Setting: Ward 86, a clinic serving publicly insured PWH in San Francisco.

Methods: We describe multilevel determinants of and strategies for LA-CAB/RPV implementation for PWH without VS, using the Consolidated Framework for Implementation Research. To assess patient and provider-level determinants, we drew on pre-implementation qualitative data. To assess inner and outer context determinants, we undertook a structured mapping process.

Results: Key patient-level determinants included perceived ability to adhere to injections despite oral adherence difficulties and care engagement challenges posed by unmet subsistence needs; strategies to address these determinants included a direct-to-inject approach, small financial incentives, and designated drop-in days. Provider-level determinants included lack of time to obtain LA-CAB/RPV, assess injection response, and follow-up late injections; strategies included centralizing eligibility review with the clinic pharmacist, a pharmacy technician to handle procurement and monitoring, regular multidisciplinary review of patients, and development of a clinic protocol. Ward 86 did not experience many outer context barriers because of rapid and unconstrained inclusion of LA-CAB/RPV on local formularies and ability of its affiliated hospital pharmacy to stock the medication.

Conclusions: Multilevel strategies to support LA-CAB/RPV implementation for PWH without VS are required, which may necessitate additional resources in some settings to implement safely and effectively. Advocacy to eliminate outer-context barriers, including prior authorizations and specialty pharmacy restrictions, is needed.
