Background: Successful treatment of latent tuberculosis infection (LTBI) is critical to reduce the impact of tuberculosis (TB). The purpose of this study was to determine the feasibility of adopting the WelTel text-messaging intervention, proven to be effective in improving HIV treatment adherence, for use in LTBI care.
Aims: (1) Determine prevalence of mobile phone ownership, text-message use, and patient attitudes towards receiving text messages from the clinic. (2) Determine the technological feasibility of the WelTel intervention, and (3) patient and healthcare provider acceptability of the service.
Methods: We conducted a cross-sectional descriptive survey of patients attending a provincial TB clinic and a pilot study in which patients initiating treatment for LTBI received the intervention for 12 weeks.
Results: Clinic survey: Of 82 participants who completed the survey between September and December 2011, 68 owned a mobile phone and 58 used text messaging weekly. Participants were receptive to receiving text-message communication from the clinic (n = 80). Pilot intervention study: Of 16 patients who received the intervention, 14 completed the study. Using software to deliver the intervention was feasible. The greatest participant-perceived benefit was that it enabled them to report side-effects quickly (n = 6); the greatest participant-perceived barrier was cost (n = 3).
Conclusion: The majority of patients in this study population had the means to communicate with their healthcare providers via text-messaging and were receptive to doing so. The intervention was well-received by participants and the healthcare provider. A randomized controlled trial is underway to determine the intervention’s effectiveness to increase LTBI treatment adherence.
