"I don't know when he will be back": life-changing events challenge the community ART Group model- a qualitative research study, Tete, Mozambique.

Changing life circumstances, changes in relationships and a lack of participation by CAG members altered the CAG dynamic, which sometimes affected adherence. Some CAGs responded to challenges by intensifying peer support, including to those diagnosed with virological failure. To ensure flexible implementation and modification of CAGs to the inevitable changes in life circumstances of its members, feedback mechanisms should be implemented between CAG members and the health-care providers.
