Tracking and Continuity of Care in Advanced HIV Disease

Despite the scale-up of HIV testing and the implementation of the universal test-and-treat policy, a substantial proportion of people living with HIV (PLHIV) continue to present with advanced HIV disease (AHD), defined by a CD4 count below 200 cells/µL and/or WHO clinical staging of stage 3 or 4. Global and regional analyses estimate that nearly half of hospitalized PLHIV meet criteria for AHD, with similar findings reported in South Africa. Patients with AHD face high risks of opportunistic infections, hospitalization, and mortality, and frequently disengage from care after discharge. This study aims to examine inpatient and post-discharge care pathways for individuals with AHD in South Africa, identify gaps in continuity of care between hospitals and primary healthcare (PHC) facilities, and generate evidence to inform strategies that strengthen linkage, retention, and long-term outcomes. A prospective cohort study with a nested process evaluation will be conducted at Helen Joseph Hospital, a large public tertiary facility in Johannesburg. Adult patients (≥18 years) admitted with HIV-related conditions and meeting AHD criteria will be consecutively enrolled once deemed clinically stable. Data will be collected through structured inpatient interviews, medical-record reviews, and follow-up telephone interviews at four- and eight-weeks post-discharge to assess linkage to PHC services, ART continuation, and readmissions. Quantitative data will be analyzed descriptively using standard statistical methods. This study will generate a detailed understanding of how patients with AHD transition from inpatient to outpatient HIV care, highlighting critical points where continuity of care fails. Findings will identify system- and patient-level barriers to effective linkage and retention and inform interventions to improve post-discharge outcomes. The study poses minimal risk to participants, involving only structured interviews and review of existing medical records, with no invasive procedures.

Advanced HIV Disease During the First Six Months on Antiretroviral Therapy in Zambia

In Zambia, an estimated 20% of HIV-positive clients continue to present for first-time antiretroviral therapy (ART) initiation or re-initiation with advanced HIV disease (AHD). The Zambia Ministry of Health (MOH) and other key stakeholders lack information about the characteristics and behaviors of AHD clients, including how they are defined and diagnosed (e.g. low CD4 count v. clinical condition), their demographic and socioeconomic profiles, their HIV care histories, what services they receive, and their short-term outcomes (achieve viral suppression, remain AHD, disengage from care, die) and the timing of these outcomes. The Retain6 project aims to improve HIV treatment outcomes during clients' first six months on ART, when disengagement from care and mortality are highest. This protocol, called Advanced HIV disease during the first six months on antiretroviral therapy in Zambia (AHD Zambia), describes an observational study that will describe the experiences of clients who are diagnosed with AHD upon ART initiation (or re-initiation) in Zambia. Data collected will include clinical and socioeconomic characteristics, clinical and non-clinical needs, services delivered and received, and clients' and providers' concerns and preferences. The study's overall goal is to provide information to the Zambia MOH, treatment program partners, providers, and other stakeholders to better understand who is presenting with AHD in Zambia, how they are currently managed, and their treatment outcomes after starting ART. This information will be useful in determining interventions and guideline changes that might improve short- and long-term outcomes for AHD patients. The study, which will be conducted in collaboration with the Zambia MOH, will include retrospective file reviews, prospective quantitative surveys with outpatient and inpatient clients, qualitative focus group discussions (FGDs) and interviews with clients, and provider surveys and interviews.

Factors Associated With Advanced HIV and Poor Nutrition Among People Living With HIV

Aim of the work: 1. To determine the frequency of advanced HIV among PLWH in Assiut University Hospital. 2. To assess the nutritional patterns and frequency of poor nutrition among PLWH. 3. To evaluate factors associated with advanced HIV disease and poor nutrition among PLWH.
