Abstract:

Integrating and sustaining evidence-based interventions (EBIs) in routine care is crucial to improving HIV treatment outcomes among youth living with HIV (YLH). However, EBIs are often not sustained post clinical trial. An Adolescent Transition Package (ATP) delivered by health care workers (HCWs) and tested in Kenya in 2021 significantly improved YLH readiness to transition to independent care. Post-trial, participating clinics could continue using the ATP. We conducted 30 in-depth interviews with health care workers to evaluate determinants of continued ATP implementation one-year post-trial. Interviews used semi-structured guides, informed by the Consolidated Framework for Implementation Research version 2.0 (CFIR v2.0). Transcripts were analyzed thematically to identify key influences of ATP sustainment and fidelity post-trial. Effective training during and after the trial, and continued internal and external support for implementation, were crucial for sustained acceptability and feasibility. In contrast, staff shortages and high turnover, lack of integration into the existing electronic medical system, and maintaining staff motivation were barriers to ATP sustainment. Implementation fidelity was limited by workforce constraints and HCW beliefs about the importance of individualizing content and delivery to be responsive to individual client needs. ATP adaptability afforded optimization of delivery to overcome workforce constraints and meet client needs, increasing HCW perceptions of feasibility and motivating continued use. Alignment between observed impact and care provision goals further motivated ongoing ATP utilization. Strategies to ensure continued training and integration of tools into existing systems have the potential to further enhance ATP sustainability.

Abstract:

Background

The COVID-19 pandemic resulted in disruptions to routine HIV services for youth living with HIV (YLH), provoking rapid adaptation to mitigate interruptions in care. The Adolescent Transition to Adult Care for HIV-infected adolescents (ATTACH) study (NCT03574129) was a hybrid I cluster randomized trial testing the effectiveness of a healthcare worker (HCW)-delivered disclosure and transition intervention — the Adolescent Transition Package (ATP). During the pandemic, HCWs leveraged phone delivery of the ATP and were supported to make adaptations. We characterized real-time, provider-driven adaptations made to support phone delivery of the ATP.

Methods

We conducted continuous quality improvement (CQI) meetings with HCWs involved in phone delivery of the ATP at 10 intervention sites. CQI meetings used plan-do-study-act (PDSA) cycles and were audio-recorded. Adaptations were coded by two-independent coders using the Framework for Reporting Adaptations and Modifications to Evidence-based Implementation Strategies (FRAME-IS). Adaptation testing outcomes (adopt, retest, or abandon) and provider experience implementing the adaptations were also recorded. We summarized adaptation characteristics, provider experience, and outcomes.

Results

We identified 72 adaptations, 32 were unique. Overall, adaptations included modification to context (53%, n = 38), content (49%, n = 35), and evaluation processes (13%, n = 9). Context adaptations primarily featured changes to personnel, format, and setting, while content and evaluation adaptations were frequently achieved by simple additions, repetition, and tailoring/refining of the phone delivery strategy. Nine adaptations involved abandoning, then returning to phone delivery. HCWs sought to increase reach, improve fidelity, and intervention fit within their context. Most adaptations (96%, n = 69) were perceived to increase the feasibility of phone delivery when compared to before the changes were introduced, and HCWs felt 83% (n = 60) of adaptations made phone delivery easier. Most adaptations were either incorporated into routine workflows (47%) or tested again (47%).

Conclusion

Adaptation of phone delivery was a feasible and effective way of addressing challenges with continuity of care for YLH during the COVID-19 pandemic. Adaptations were primarily context adaptions. While FRAME-IS was apt for characterizing adaptations, more use cases are needed to explore the range of its utility.

Abstract:

Implementation science (IS) uses systematic methods to close gaps between research and practice by identifying and addressing barriers to implementation of evidence-based interventions (EBIs). To reach UNAIDS HIV targets, IS can support programs to reach vulnerable populations and achieve sustainability. We studied the application of IS methods in 36 study protocols that were part of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA). Protocols focused on youth, caregivers, or healthcare workers in high HIV-burden African countries and evaluated medication, clinical and behavioral/social EBIs. All studies measured clinical outcomes and implementation science outcomes; most focused on early implementation outcomes of acceptability (81%), reach (47%), and feasibility (44%). Only 53% used an implementation science framework/theory. Most studies (72%) evaluated implementation strategies. Some developed and tested strategies, while others adapted an EBI/strategy. Harmonizing IS approaches allows cross study learning and optimization of delivery of EBIs and could support attainment of HIV goals.
