Use of Smartphone-Based Video Directly Observed Therapy to Increase Tuberculosis Medication Adherence: An...

Tuberculosis (TB) treatment through Directly Observed Therapy (DOT) has an alternative form of video surveillance therapy (VOT) that utilizes the technological capabilities of smartphones to provide patients with low-cost access to doctors without impacting their work and personal life. We aimed to assess TB patients' drug compliance, perceptions, and feasibility towards smartphone-based video direct observed therapy (VDOT) in Jeddah, KSA.

We conducted a prospective non-randomized interventional study. We delivered smartphone-based VDOT among previously unstudied patients to monitor adherence to the treatment regimen. The expected total number of VDOT sessions was1200. We conducted post-intervention interviews to assess acceptability and satisfaction.

In this study, we included 20 participants, 16 of whom were males, with a mean age of 34.3 (±12.5) years. No side effects to the treatments were identified in all participants. The adherence rate for the total period was 93% and 99.5%, measured by the first and second methods, respectively. Most participants were satisfied with the VDOT experience, the time spent on sessions, and the approach's privacy.

This study provides promising results for the feasibility and effectiveness of smartphone-based VDOT for TB treatment to increase adherence which was indicated by a high compliance rate, acceptability, and high satisfaction level.
