Impact of the COVID-19 pandemic on the HIV care continuum and associated factors in middle-income countries: A mixed-methods systematic review.

Introduction: The HIV care continuum during the COVID-19 era faced specific challenges. The pandemic, affecting the delivery of HIV care, exacerbated existing healthcare inequities and vulnerabilities in middle-income countries with limited financial resources. This study aims to set the stage for the systematic review, focusing on the impact of COVID-19 on HIV care in middle-income countries with a focus on barriers and facilitators.

Methods: A systematic search of relevant literature, including electronic databases and manual assessment of references, was done. The review included quantitative, qualitative and mixed-methods studies conducted in middle-income countries, with no age or gender restrictions. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for reporting the results.

Results: In the course of our systematic review, a comprehensive examination of the pertinent literature published between 2020 and 2024 yielded a total of 76 studies. This adverse impact was prominently attributed to an amalgamation of factors intrinsically associated with pandemic-induced restrictions, fear of contracting the COVID-19 and fear of disclosing HIV status. Moreover, an emergent theme observed in select studies underscored the enduring trend of HIV treatment continuity, which was facilitated by the burgeoning utilization of telemedicine within this context.

Discussion: The pandemic negatively affected income and increased vulnerability to HIV across all phases of the HIV care continuum, except for viral suppression. Prevention measures, such as pre-exposure prophylaxis (PrEP), were compromised, leading to increased risky behaviours and compromised mental health among people living with HIV. HIV testing and diagnosis faced challenges, with reduced access and frequency, particularly among key populations. The pandemic also disrupted linkage and retention in care, especially in urban areas, exacerbating barriers to accessing necessary HIV treatment. Additionally, this review highlights the complex and multifaceted landscape of the pandemic's impact on HIV medical appointments, adherence and treatment engagement, with various barriers identified, including fear of COVID-19, economic constraints and disruptions in healthcare services.

Conclusions: The coexistence of pandemics has had negative effects on the HIV care continuum, with restrictions on services, an increase in care gaps and a break in the transmission chain in middle-income countries.
