Notes:

• Regional and country level aggregate data are generated from regional patient-level databases, using the IeDEA Data Exchange Standard (DES). All ART-naïve patients newly enrolling into HIV care from 2010 to present are included. The following patients are excluded from aggregate data measures: patients with incomplete data related to age, sex, and site of enrollment; patients with evidence of ART initiation prior to the date of enrollment; patients with less than 15 months between enrollment and database close; and patients known to have transferred to another site of care within 15 months of enrollment.
• ART initiation: Initiation of a combined regimen of antiretroviral medications after enrollment.
• Viral load monitoring at 6 months (+/- 3 months) and 12 months (+/- 3 months) after enrollment.
• Viral suppression: Viral load <1,000 copies/mL among patients with a viral load measure at 6 months or 12 months after enrollment. Patients with no viral load monitoring are excluded from the measures. For patients with >1 viral load measure at 6 months or 12 months after enrollment, the lowest viral load measure is used.
