IntroductionTreatment of latent tuberculosis infection (LTBI) decreases risk of progression to active tuberculosis. Traditional treatment regimens required either daily isoniazid for 9 months, with historically poor compliance, or 12-week directly observed therapy (DOT) with isoniazid and rifapentine, with improved compliance but additional challenges of coordinating weekly clinic visits, further complicated if patients must travel a great distance for care.Materials And MethodsOur referral area is complicated by congested traffic often resulting in one-way commutes, which can exceed 2 hours. These travel times would be prohibitive for conducting weekly in-clinic DOT. In an effort to improve access to DOT, we implemented TeleMedicine LTBI DOT (vDOT) within a military pediatric infectious diseases clinic. Patients aged 24 months or older diagnosed with LTBI were referred for possible enrollment into our vDOT clinic. All patients without contraindications for receiving isoniazid and/or rifapentine were offered LTBI treatment via weekly vDOT or daily treatment with isoniazid or rifampin. The first visit for vDOT patients was performed in person to discuss treatment options, demonstrate use of TeleMedicine software, and ensure the patient was able to take the medications. Baseline information about patients and travel time to our facility was determined.ResultsTo date, 16 patients have completed LTBI therapy using vDOT. Average one-way travel time to our facility for patients was 51 minutes. Actual time spent in most vDOT encounters was less than 10 minutes. Appointments were arranged to take place outside usual school and work hours so patients could complete vDOT with minimal interruptions to daily life, resulting in 100% treatment compliance and completion.DiscussionConducting LTBI DOT using TeleMedicine is a viable and time-saving measure that still allows for high levels of patient compliance and treatment completion while minimizing interruptions to academic and work schedules.© The Association of Military Surgeons of the United States 2021.
