Assessment of the quality of HIV data in an electronic system in a health sub-district in the Eastern Cape
MetadataShow full item record
In South Africa, public health facilities provide free antiretroviral treatment (ART) mainly via primary healthcare (PHC) nurses. To streamline data collection an electronic HIV information system (TIER.Net), was introduced in 2010. Data originates in paper-based records completed by clinicians with the data from these paper systems then being captured into TIER.Net by clerical data capturers. TIER.Net is designed to effectively monitor outcomes of the ART programme and generate information for planning, management and decision making. For Enock Mgijima subdistrict to attain these functions, it is imperative that data collected at the 21 PHC facilities in the sub-district be of good quality. There has been uncertainty around the quality levels of the data collected through the paper records and TIER.Net, and it was unclear which factors promote or inhibit improved data quality.
