A Systematic Review and Meta-analysis of the Impact of the COVID-19 Pandemic on Access to HIV Pre-exposure Prophylaxis: Lessons for Future Public Health Crises

Abstract

Background: The World Health Organization is committed to strengthening access to pre-exposure prophylaxis (PrEP) for HIV prevention and its integration into primary care services. Unfortunately, the COVID-19 pandemic has disrupted the delivery of primary care, including HIV-related services. To determine the extent of this disruption, we conducted a systematic review and meta-analysis of the changes in access to PrEP services during the pandemic and the reasons for these changes.

Methods: A search was conducted using PubMed, Scopus, Embase, PsycINFO, and Cinahl for studies published between January 2020 and January 2023. Selected articles described self-reported disruptions to PrEP service access associated with the COVID-19 pandemic or its responses. Pooled effect sizes were computed using a random-effects model.

Results: Thirteen studies involving 12,652 PrEP users were included in our analysis. The proportion of participants reporting a disruption in access to PrEP services during the COVID-19 pandemic ranged from 3% to 56%, with a pooled proportion of 21% (95% confidence intervals: 8% to 38%). Social restrictions, financial constraints, and limited health insurance coverage were key factors affecting access to PrEP services during the pandemic.

Conclusions: To our knowledge, this is the first meta-analysis to quantify the extent of disruptions to accessing PrEP services because of the COVID-19 pandemic. To increase the ability of primary care services to maintain PrEP services during public health crises, a mixture of strategies is worth considering. These include multi-month PrEP prescriptions, telehealth services, deployment of peer support groups to provide a community-based service or home delivery, and provision of financial support interventions.
