The engagement elements of the cascade document how well systems of care are working for people living with HIV. Are people diagnosed in a timely way? Are they promptly referred to the care? Are systems in place to support them in using antiretroviral treatment effectively?
Research on engagement often focuses on barriers and facilitators. What individual and system factors stop people from having sustained access to care? What interventions could support people in regularly access HIV care and could help them maintain their health and well-being? What interventions would facilitate the optimal use of care services by individual and specific populations affected by HIV?
