Baseline characteristics by cohort
Measure
Pre-Intervention Control Group
n=45 Participants
Eligible participants from a pre-intervention period (January-August 2012) prior to their receiving SMS messages about their laboratory test results. During the pre-intervention stage, clinicians completed eligibility forms for each participant, including confirmation of access to a cellular phone, district of residence, and selection of the abnormal result threshold for the cluster of differentiation 4 (CD4) test, which would prompt a request for an early return to clinic. Standard clinical forms were completed to collect data on sociodemographic and clinical characteristics. We also collected data on the laboratory result and result date, time from laboratory result to clinic return, and for antiretroviral therapy (ART) naive participants, time to ART initiation.
Intervention Period
n=138 Participants
Participants in the intervention period (September 2012 - November 2013) were receive daily short message service (SMS) messages for up to seven days in one of three formats: 1) messages reporting an abnormal result directly, 2) personal identification number-protected messages reporting an abnormal result, or 3) messages reading "ABCDEFG" to confidentially convey an abnormal result. For our a priori hypothesis, we aimed to test whether clinical outcomes, i.e. time to clinic return and time to ART initiation, were different in the pre-intervention and intervention period. This was a non-randomized allocation. During the intervention period, clinicians used eligibility criteria identical to those used during the pre-intervention period, including selection of an abnormal cluster of differentiation 4 (CD4) count threshold to trigger the SMS and transportation reimbursement intervention.

PRIMARY outcome

Timeframe: 28 days

Population: These are participants who were Antiretroviral Therapy naive, and so analysis of this measurement is using this subgroup only.
