  • Record linkage without patient identifiers

    Open AccessKhumbo Shumba, Joep Bor et al.ARTICLEPLOS Global Public Health2025

    Linkage between health databases typically requires patient identifiers such as names and personal identification numbers. We developed and validated a record linkage strategy to combine administrative health databases without identifiers for South Africa’s public sector HIV program. We linked CD4 counts and HIV viral loads from South Africa’s TIER.Net with the National Health Laboratory Service (NHLS) database for patients receiving care between…

  • The fall—And rise—In hospital-based care for people with HIV in South Africa

    Open AccessEvelyn Lauren, Khumbo Shumba et al.ARTICLEPLOS Global Public Health2024

    ART scale-up has reduced HIV mortality in South Africa. However, less is known about trends in hospital-based HIV care, which is costly and may indicate HIV-related morbidity. We assessed trends in hospital-based HIV care using the National Health Laboratory Service (NHLS) National HIV Cohort. Our study included all adults ≥18 years receiving care in South Africa’s public sector HIV program from 2004 to 2017 with at least one CD4 count/viral load…

  • Assessment of facility-level antiretroviral treatment patient status utilizing a national-level laboratory cohort

    Open AccessJoshua P Murphy, Khumbo Shumba et al.ARTICLEFrontiers in Public Health2022

    Background: Most estimates of HIV retention are derived at the clinic level through antiretroviral (ART) patient management systems, which capture ART clinic visit data, yet these cannot account for silent transfers across HIV treatment sites. Patient laboratory monitoring visits may also be observed in routinely collected laboratory data, which include ART monitoring tests such as CD4 count and HIV viral load, key to our work here. Methods: In t…
