Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Tuberculosis (TB) is still present in Switzerland, and concerns mainly foreign-born subjects. Monitoring compliance to treatment by Directly Observed Therapy (DOT) is strongly encouraged by the World Health Organization (WHO). It is however time-consuming, costly and stigmatising. This study aims to examine the feasibility of monitoring compliance through a secured web platform and videos sent via an application on a cellphone, a concept known as vDOT (Video-observed therapy). The study aims to include all patients treated for tuberculosis is on our area during an 18 month period and monitor acceptance, compliance, and technical issues related to vDOT.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study aims to include all patients who are treated de novo for active tuberculosis is our area. The aim of this study, was to show that vDOT was feasible in a low-incidence high income area, that it had a high acceptance rate among patients and health-care professionals, with a low rate of technical difficulties or pitfalls.

All patients with a diagnosis of tuberculosis irrespective of site(s) of infection, were invited to participate in this study. The Division of Pulmonology of Geneva University Hospital diagnoses and follows virtually all cases of tuberculosis in the Canton of Geneva. Annual number of cases in Geneva between 2020 and 2023 was on average 43/year (range: 36-53). Incidence was 7-10.3/105 inhabitants compared to a national incidence of 3.99-4.72 /105 inhabitants during the same period.

Specialized TB nurses were trained to use the vDOT platform and provided the training with the help of translators whenever required. The application (APP) was installed with the patient, and a test video was sent to the platform. The APP uses simple understandable pictograms and is thus not per se language-dependent . vDOT was started as soon as possible after initiation of TB treatment, either during a hospital stay or during the first outpatient follow-up visit at our centre. Whenever necessary, a portable cell phone was provided for the patient, for the duration of the treatment.

The SureAdhere platform was used for vDOT (https://dimagi.com/sureadhere/). Once the videos have been recorded, they are sent automatically as soon as the patients' cell phone has access to internet.

For each patient, the number of videos to be sent each week was specified (5 as default option).
