Model adjusted for age, viral load, number of scheduled appointments, insurance, and clinic site. Missing data on age, viral load, and insurance are excluded from the table. Patients with a single postanchor scheduled appointment were also excluded.
Abbreviations: HIV, human immunodeficiency virus; IDUs, injection drug users; MSM, men who have sex with men; RW, Ryan White coverage.
a Change in retention measure from preintervention period to intervention period, expressed as a percentage of the measure for the preintervention period.
b Based on clinical records no more than ±99 days from anchor visit in preintervention and intervention periods.
c Undetectable viral loads were defined as HIV RNA levels ≤400 copies/mL.
d Patients with only a single postanchor scheduled visit were not included in this model.
e “Other” category includes other risk factors, unknown or undetermined risk factors, and no risk factors identified.
f For insurance, “other” includes university and local charity programs.
