Enhanced Surveillance in a Digital Health Landscape: The Role of the Near-Real Time Right to Care Knowledge Centre within South Africa’s APACE HIV Program
Abstract Introduction: Right to Care (RTC), through support from the United States Agency for International Development (USAID) implements innovations that improve data accessibility and utilization for improved program performance and patient outcomes for large scale HIV care and treatment programs. Frequent and accessible data, coupled with changes to business practices to use that data, allow for targeted and timely HIV program interventions that impact patient outcomes in Ehlanzeni district, Mpumalanga, South Africa.Methods: In South Africa, within the USAID Accelerating Program Achievements to Control the Epidemic (APACE) program, the Knowledge Centre (KC) – an interoperable automated data warehouse and visualization near real-time solution - allow for rapid daily assessment of over- and under-performance cross-sectionally. The authors established the impact of the KC intervention for 29 USAID-selected Siyenza facilities, before the KC intervention (Dec 2018 to Feb 2019) compared to HIV outcomes during the KC intervention (March 2019 to May 2019), stratified by facility classification as included or not included in the Siyenza program using both non-parametric and parametric methodologies.Results: Average facility ART initiations increased by 16% from a monthly average of 54 new initiations pre-Siyenza to 62 new ART initiations during Siyenza; retention increased to a net retention in care ratio of 1.15 indicating that patients labelled as lost to care were brought back. An independent-samples t-test indicated that the net retention in care scores were significantly higher for Siyenza facilities (M =.379, SD =.808) compared to non-Siyenza facilities (M=-.061, SD =1.016), t(208) = 2.224, p < 0.027, d = .445 during the Siyenza period. A significant difference was noted between the means with a 62.3% chance that the Siyenza facilities have a higher observed mean than the non-Siyenza facilities during the intervention period. Results indicate that Siyenza facilities maintain cohort growth, while non-Siyenza facilities continued to lose patients. Conclusion: The accessibility and utilization of near to real-time interoperable data within HIV programs allowed for rapid responses to program performance, needs and improved patient outcomes. Daily data review meetings facilitated precision programming and contributed to the behavior change necessary to institute routine data use for decision making and evaluations within programs.
