Implementation Science to Enhance HIV Testing Services During Emergency Care in Kenya

Rövid összefoglaló (regiszter, angolul)

There are ~38 million people living with HIV (PLH), with the majority in low-and middle-income countries (LMICs), where the UNAIDS 95-95-95 HIV targets are at risk of not being achieved. Data show that incident infections are concentrated in sub-Saharan Africa and focused in difficult to reach populations. These harder to reach persons frequently also have higher-risk profiles for HIV, making them essential target populations to receive HIV Testing Services (HTS). Among target populations, men, adolescents and young adults (AYAs) aged 15-24 years, and persons from key populations (KPs) represent crucial groups to be reached. In Africa, Emergency Departments (ED) provide care to large numbers of persons that often do not otherwise access health services. Data from Africa show that those seeking emergency care have high burdens of HIV, and desire ED-HTS. As in higher-income countries, EDs in LMICs provide a strategic opportunity to deliver evidence-based HTS interventions to higher-risk persons. In Kenya one in five PLH are unaware of their status, less than half of men are reached for HIV testing at appropriate frequencies, AYAs account for 42% of new infections and KPs contribute to hyper-endemic transmission. To address this, Kenya national strategy calls for utilizing facilities-based care to deliver HTS for difficult to reach populations. However, while the guidelines include EDs as service delivery points, HTS during emergency care in Kenya is still evolving and the evidence-base on best practices is in early development. The HIV Enhanced Access Testing in Emergency Department (HEATED) program in Kenya was developed by a collaborative team led by PI Aluisio (K23AI145411). The HEATED program was derived using the Capability-Opportunity-Motivation Behavioral model to enhance delivery of HTS, through locally appropriate and pragmatic systems initiatives. HEATED program implementation significantly improved HIV testing for the overall ED population by 31%, while also significantly increasing testing for men, AYA and KP and was found to be acceptable by stakeholders. Although pilot evaluation of the HEATED program demonstrated improved HTS for target populations, more robust understanding of optimal implementation strategies in ED settings, impacts on linkage to HIV care outcomes, costing and maintenance data are needed to inform development of ED-HTS programming in Kenya. To address this, the current proposal will build upon the HEATED program by evaluating use of the Systems Analysis and Improvement Approach (SAIA) implementation strategy (HEATED-SAIA) to improve HTS in a cluster randomized trial in all Ministry of Health EDs in Kilifi, Mombasa and Kwale Counties of the Coast Region of Kenya. The Reach, Effectiveness, Adoption, Implementation and Maintenance framework with quantitative and qualitative data will be used in trial assessment. Building on the K23 pilot data and leveraging SAIA, the HEATED-SAIA program has substantial potential to improve HTS delivery by strategically and pragmatically engaging difficult to reach populations already interfacing with emergency health systems, while being acceptable and cost-effective.
