Postpartum Adherence Clubs for Antiretroviral Therapy (PACART)

17. mai 2022 oppdatert av: Professor Landon Myer, University of Cape Town

Postpartum Adherence Clubs for Antiretroviral Therapy: a Randomised Controlled Trial

South Africa is implementing the policy of universal initiation of lifelong antiretroviral therapy (ART) in all HIV-infected pregnant women regardless of CD4 cell count or disease stage ("Option B+"). There is a recognised need for innovative models of service delivery to support adherence and retention in care in this group, particularly during the postpartum period. The investigators are conducting a pragmatic randomised control trial to compare virological outcomes 24 months postpartum in two models of service delivery for provision of HIV care and treatment services postpartum in women who initiated ART during pregnancy: local adult ART clinics and community-based adherence clubs.

Detaljert beskrivelse

South Africa is implementing the policy of universal initiation of lifelong ART in all HIV-infected pregnant women regardless of CD4 cell count or disease stage ("Option B+") and given the high antenatal HIV seroprevalence, HIV-infected pregnant women represent the largest group of patients initiating ART in primary care facilities. However, there are few well developed models of service delivery to support implementation. There are particular concerns regarding the postpartum period, with multiple studies indicating high levels of non-retention in care and/or inadequate adherence to treatment postnatally. Adherence Clubs (ACs) are an innovative but untested model of care based on chronic disease management strategies that emphasize social support, adherence to treatment and retention in care, rather than intensive clinical management, as the most important determinant of long-term health outcomes in stable patients in chronic care. ACs have preliminarily been shown to to result in virologic outcomes that are similar to routine clinic services in patients stable on ART. The investigators are conducting a pragmatic, randomised controlled trial to evaluate two different strategies for delivering HIV care and treatment services during the postpartum period to HIV-infected women who initiated ART during pregnancy. Participants will be allocated to receive ART care at either local adult ART clinics, following the current standard of care, or the community-based adherence club system.

Beskrivelse

Inclusion Criteria:

  • Documented HIV infection with ART initiation during the preceding antenatal period
  • Within 70 days post-delivery
  • Viral suppression documented in pregnancy with the most recent viral load <400 copies/mL within the last 3 months

Exclusion Criteria:

  • Intention to relocate out of Cape Town permanently during the study period

  • Loss of pregnancy/neonate at the time of eligibility determination
  • Current co-morbidity requiring additional health care attention, including opportunistic infections such as tuberculosis (TB) disease or any chronic condition or other condition that is not controlled or stable

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Ingen inngripen: Clinic-based Care
Clinic-based care is the current standard of care and is defined as referral of women on antiretroviral therapy (ART) to general primary care adult ART services.
Eksperimentell: Adherence Club Care
Adherence club care involves referral of women on ART to community-based ART services in the form of adherence clubs, which are led by community health workers and supported by ART clinic nurses.
Annen: Adherence Clubs
Women will be referred to the ACs at their postpartum ART clinic visit at the midwife obstetric unit (MOU) at the Gugulethu community health centre (CHC). AC visits occur 2-4 monthly at a community hall near the CHC. At routine visits, which last ~1 hour, community health workers provide health education, weigh participants, ask about symptoms, and dispense pre-packed ART. Symptomatic participants are referred back to the main ART facility at the CHC for assessment by a nurse. A nurse performs routine phlebotomy at an annual club visit, and does a clinical assessment and reviews blood results at the subsequent visit. Participants requiring more regular follow-up and those with raised viral loads are referred back to the ART clinic at the CHC by the nurse.
