INTRODUCTION
The retention in care of patients undergoing antiretroviral therapy (ART) is a cornerstone for preventing AIDS‐associated morbidity and mortality, as well as further transmission of HIV. Adherence to ART poses particular challenges in conflict‐affected settings like the Central African Republic (CAR). The study objective was to estimate the rate of lost‐to‐follow‐up (LTFU) and determine factors associated with LTFU among patients living with HIV under ART in CAR.
METHODS
A retrospective cohort analysis was conducted using data from patients being managed at 42 representative ART dispensing sites (i.e. management of ≥200 patients) in the seven health regions of CAR which started ART between January 2019 to September 2021 and followed up to December 2021. The outcome of LTFU was defined as a failure of a patient to attend a scheduled ART refill appointment for at least 90 days from the last appointment. Patients were censored at the first LTFU event.
RESULTS
A total of 6844 patients enrolled in ART care were included in the analysis, of whom 67.5% were females. The mean age (standard deviation) was 35.3 years (10.5). Forty‐two per cent (n = 2874/6844) had an LTFU event during the follow‐up period. However, 23.2% (n = 666/2874) returned to care after LTFU. Overall retention in antiretroviral care at 12 months was 64.2% (CI 63.0−65.5), which ranged from 76.1% in the capital to 48.2% in the inner country region. Risk factors related to LTFU were being male (adjusted hazard ratio [aHR] 1.33; CI 1.1−1.5), age < 25 (aHR 1.46; CI 1.1−1.9), living in regions outside the capital (aHR 1.83; CI 1.6−2.3) and undernutrition (aHR 1.13; CI 1.0−1.3).
CONCLUSIONS
Retention to care in CAR is suboptimal, especially in the inner country. Our results underline the difficulties involved in retaining patients in ART in complex settings, the interplay between poor retention, social unrest, stigma, food insecurity and HIV epidemic control, and the need for tailored programming and interventions like differentiated treatment strategies and complementary food provision.
Youth living with HIV (YLWH) are less likely to initiate antiretroviral therapy (ART) and remain in care than older adults. It is important to identify effective strategies to address the needs of this growing population and prevent attrition from HIV care. Since 2008, two clinics have offered youth-targeted services exclusively to youth aged 12-25 in Khayelitsha, a high HIV-prevalence, low-income area in South Africa. We compared ART attrition among youth in these two clinics to youth in regular clinics in the same area.
METHODS
We conducted a propensity score matched cohort study of individuals aged 12-25 years initiating ART at eight primary care clinics in Khayelitsha between 1 January 2008 and 1 April 2018. We compared attrition, defined as death or loss to follow-up, between those attending two youth clinics and those attending general primary healthcare clinics, using Cox proportional hazards regression. Follow-up time began at ART initiation and ended at attrition, clinic transfer or dataset closure. We conducted sub-analyses of patients attending adherence clubs.
RESULTS
The distribution of age, sex and CD4 count at ART initiation was similar across Youth Clinic A (N = 1383), Youth Clinic B (N = 1299) and general clinics (N = 3056). Youth at youth clinics were more likely than those at general clinics to have initiated ART before August 2011 (Youth Clinic A: 16%, Youth Clinic B: 23% and general clinics: 11%). Youth clinics were protective against attrition: HR 0.81 (95% CI: 0.71-0.92) for Youth Clinic A and 0.85 (0.74-0.98) for Youth Clinic B, compared to general clinics. Youth Clinic A club patients had lower attrition after joining an adherence club than general clinic patients in adherence clubs (crude HR: 0.56, 95% CI: 0.32-0.96; adjusted HR: 0.48, 95% CI: 0.28-0.85), while Youth Clinic B showed no effect (crude HR: 0.83, 95% CI: 0.48-1.45; adjusted HR: 1.07, 95% CI: 0.60-1.90).
CONCLUSIONS
YLWH were more likely to be retained in ART care in two different youth-targeted clinics compared to general clinics in the same area. Our findings suggest that multiple approaches to making clinics more youth-friendly can contribute to improving retention in this important group.
