BACKGROUND

Pediatric programs face a high rate of loss to follow-up (LTFU) among children and adolescents living with HIV (CAHIV). We assessed true outcomes and predictors of these among CAHIV who were LTFU using linkage to the Western Cape Provincial Health Data Centre at Western Cape sites of the International epidemiology Databases to Evaluate AIDS-Southern Africa collaboration.

METHODS

We examined factors associated with self-transfer, hospital admission and mortality using competing risks regression in a retrospective cohort of CAHIV initiating antiretroviral therapy <15 years old between 2004 and 2019 and deemed LTFU (no recorded visit at the original facility for ≥180 days from the last visit date before database closure and not known to have officially transferred out or deceased).

RESULTS

Of the 1720 CAHIV deemed LTFU, 802 (46.6%) had self-transferred and were receiving care elsewhere within the Western Cape, 463 (26.9%) had been hospitalized and 45 (2.6%) CAHIV had died. The overall rates of self-transfer, hospitalization, mortality and LTFU were 9.4 [95% confidence interval (CI): 8.8-10.1], 5.4 (95% CI: 5.0-6.0), 0.5 (95% CI: 0.4-0.7) and 4.8 (95% CI: 4.4-5.3) per 100 person-years respectively. Increasing duration on antiretroviral therapy before LTFU was associated with self-transfers while male sex, older age at last visit (≥10 years vs. younger) were associated with hospital admission and immune suppression at last visit was associated with 5 times higher mortality.

CONCLUSIONS

Nearly half of CAHIV classified as LTFU had self-transferred to another health facility, a quarter had been hospitalized and a small proportion had died.
