| Summary: | This report presents the findings of a
large spatial analysis of almost 3 million viral load tests
from over 2 million HIV patients on antiretroviral therapy
in South Africa. It is part of the second phase of a series
of analytical and evaluation studies contributing to the
design of an impact and process evaluation of South Africa’s
National Adherence Guidelines for Chronic Diseases. The
analysis was conducted by the National Health Laboratory
Service (NHLS) and Boston University/Health Economics and
Epidemiology Research Office (HE2RO), in collaboration with
the National Institute for Communicable Diseases (NICD), the
National Department of Health of South Africa, and the World
Bank. A number of other institutions contributed in the
multi-step process of creating a patient-linked cohort
through a novel record linkage algorithm and a masterlist of
public sector health facilities, which are both underpinning
this analysis and described in the report. The analysis
demonstrates the diversity in the proportion of HIV patients
getting a viral load test annually and patients virally
suppressed. The variation shows by geographic location and
facility, as well as by age, gender and demography. It sheds
light on high viral load levels in young HIV patients on
treatment. Also, one in six male and one in nine female ART
patients were identified as having a high risk of HIV
transmission due to viral load levels above 10,000 copies/mL |
