Key Points Question Is electronic directly observed therapy (DOT) noninferior to in-person DOT in supporting medication adherence for tuberculosis treatment? Findings In this randomized, 2-period crossover noninferiority trial of 216 patients with tuberculosis, the modified intention-to-treat analysis estimate of the percentage of medication doses staff observed patients ingest with in-person DOT was 87.2% vs 89.8% with electronic DOT. The percentage difference between DOT methods was −2.6%, which was less than the noninferiority margin of 10% at a statistically significant level. Meaning These findings suggest that electronic DOT was noninferior to in-person DOT when employed by a tuberculosis program that has historically implemented in-person DOT successfully.
