Primary care- dominant models	1. Exclusively primary care—patient is assigned to a regular family physician who provides most care; no infectious disease or internal medicine physician provides any HIV care
	2. Family physician-dominant co-management—patient is assigned to a regular family physician who provides the majority (50% or more) of HIV-related care; specialist physician provides some HIV care
Specialist- dominant models	3. Specialist-dominant co-management—patient is assigned to a regular family physician, but specialist physician provides the majority (50% or more) of HIV-related care
	4. Specialist care only—patient is not assigned to a regular family physician; specialist physician provides all HIV-related care
	5. Low engagement—patient is not assigned to a regular family physician and has no specialist physician providing HIV care
