    Abstract
    This is the microdataset used in the paper "SMS nudges as a tool to reduce Tuberculosis treatment delay and pretreatment loss to follow-up. A randomized controlled trial". We fielded two SMS interventions in three Cape Town clinics to see their effects on whether people returned to clinic, and how quickly. One was a simple reminder; the other aimed to overcome “optimism bias” by reminding people TB is curable and many millions die unnecessarily from it. Recruits were randomly assigned at the clinic level to a control group or one of the two SMS groups (1:2:2). In addition to estimating effects on the full sample, we also estimated effects on HIV-positive patients.

    Scope

    Notes

    The dataset includes: outcomes (whether the patient returned to get their TB test results and if so how quickly); information on demographics, education, housing, family circumstances etc.; intervention group assignment; HIV status; and whether the intervention was delivered correctly (an exclusion variable for the per-protocol analysis).

    Coverage

    Sampling

    Sampling Procedure

    Patients not already being treated for TB arriving in TB waiting rooms of 3 clinics. Aimed to recruit > 90% of new patients over recruitment period. Inclusion criteria: Adult, provided consent, not already on treatment, waiting for a TB test or just had a TB test. Exclusion criteria: Adult, refused consent, already on treatment, not waiting for a TB test or just had a TB test. Recruitment was from 2 October 2017 until 15 December 2017. Fieldworkers continued visiting clinics and phoning patients until mid-February 2018 to collect data on patients’ return-to-clinic date, test results and treatment start date.

    Questionnaires

    CAPI interview at recruitment was based on a long questionnaire only a few questions from which were used in the present study. The questionnaire is therefore not attached to the current dataset.

    Supervision

    Multiple fieldworkers were used overseen by a project coordinator overseen in turn by co-PI Prof. Ronelle Burger. Fieldworkers collected initial and follow-up data in tablets, and uploaded the data to a central server. The project coordinator undertook the randomization to the control and two treatment groups as described in the paper.

    Data Collection Notes

    Initial data collected through CAPI interview at time of recruitment. Data on return-to-clinic date were obtained via fieldworker interactions with returning patients in the TB waiting room, conversations with clinic staff, and where necessary, phone follow-up conversations with patients and inspection of clinic records. HIV status was obtained by matching between our dataset and the PREHMIS and ETR.Net datasets as described in the paper. The data for the exclusion criteria for the per-protocol analysis were obtained from the records of the bulk SMS provider used to send the SMS messages,

    Data processing

    Data Editing

    Data-cleaning was done by staff at Stellenbosch University and the World Bank.
