Acceptability of reduced time to spaced-out appointments, as measured by the number of instances when providers overrode the study assignment. Override could only occur a maximum of one time for each participant.

Repeated measures analysis of participant direct and indirect costs. While we initially planned to report measurements at 1-, 6- and 12-months after enrollment in ART care, we ultimately reported direct and indirect average costs at 12 months by adding the reported costs at each of the 3 time points to calculate the cost over the entire study period, and then dividing by the number of visits to the health center.

Repeated measures analysis of patient self-reported ART adherence

Repeated measures analysis of participant quality of life as measured by the EuroQOL-5 Dimension-5 Levels (EQ-5D-5L) Visual Analog Scale (VAS). The EQ-5D-5L is a 5-level scale that measures self-rated problems (no problems, slight problems, moderate problems, severe problems and extreme problems) in 5 domains (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) as well as self-rated health. For this measure, we chose to use only the VAS, which asks respondents to rate their overall health from 0-100, with higher scores indicating greater self-rated health.

The Satisfaction With Care scale is a 9-item scale containing questions about satisfaction with clinical (n=6) and non-clinical elements (n=3) of health care. Participants describe satisfaction with each element on a 5-point Likert scale (very unsatisfied [1], not satisfied [2], no opinion [3], satisfied [4], very satisfied [5]). Satisfaction with clinical and non-clinical care elements are reported separately, by summing scores (1-5) for each item and then dividing by the number of items within each subscale. Subscale scores range from 1 to 5; higher scores indicate greater satisfaction.

As measured by an adapted version of the HIV stigma scale (anticipated stigma). Anticipated stigma is rated on a 5-point Likert-type scale (Very Unlikely [1] to Very Likely [5]), with higher scores indicating greater stigma. Items are averaged to create a composite score.

As measured by the HIV/AIDS Stigma Instrument-PLWA (HASI-P) Scale. The HASI-P is a 33-item scale that contains questions in 6 different stigma-related domains or factors. For each item, participants are asked to describe the frequency of experienced stigmatizing events in the past 3 months on a 4-point Likert scale (0- Never, 1- Once or twice, 2- Several times, or 3- Most of the time), with higher scores indicating greater stigma. The instrument is scored by summing the scores (0-3) for each item and then dividing by the number of items within each factor (enacted or internalized stigma).

Advance to spaced-out appointments at month 6 after two viral loads are measured.

Early spaced-out appointments: Newly-diagnosed PLWH currently attend health centers monthly for ART pick-up and quarterly for clinical visits. In this arm, starting at 6 months after ART initiation, participants whose 3- and 5-month viral loads are both suppressed attend health centers quarterly for ART pick-up and semi-annually for clinical visits.

Proportion of participants that attended all pharmacy and clinical appointments

Appointment adherence was defined in the protocol as the proportion of participants in each arm who attended all scheduled clinical appointments and ART pick-ups during the study. We planned to ascertain appointment adherence through review of participants' medical files at the conclusion of the study. During medical file review, it became apparent that scheduled appointments (i.e. next planned) were inconsistently documented. We therefore were unable to accurately ascertain this outcome.

Acceptability of reduced time to spaced-out appointments, as measured by the number of instances when providers overrode the study assignment. Override could only occur a maximum of one time for each participant.

Overriding of study assignment was only examined for participants in intervention arms (Early 1 and Early 2). 3 enrolled participants were assigned to groups (one participant to the 'Early 1' group and two participants to the 'Usual Care' group), but subsequently withdrawn from the study when it became clear that they did not meet eligibility criteria. As such, data for one 'Early 1' group participant was not included in the analyses.
