Outcomes and implementation challenges of using daily treatment regimens with an innovative adherence support tool among HIV-infected tuberculosis patients in Karnataka, India: a mixed-methods study
In India, a new care package consisting of (i) daily regimen with fixed-dose combination drugs, collected once-a-month and self-administered by the patient, (ii) ‘one stop service’ at antiretroviral treatment (ART) centre for both HIV and tuberculosis (TB) treatment and (iii) technology-enabled adherence support (99DOTS, which required patients to give a missed phone call after consuming drugs) was piloted for treatment of TB among HIV-infected TB patients. Conventional care included intermittent regimen (drugs consumed thrice-weekly) delivered under direct observation of treatment supporter and the patients needing to visit TB and HIV care facilities, separately for treatment.
Smartphone-enabled video-observed versus directly observed treatment for tuberculosis: a multicentre, analyst-blinded, randomised, controlled superiority trial
Directly observed treatment (DOT) has been the standard of care for tuberculosis since the early 1990s, but it is inconvenient for patients and service providers. Video-observed therapy (VOT) has been conditionally recommended by WHO as an alternative to DOT. We tested whether levels of treatment observation were improved with VOT.
The impact of digital health technologies on tuberculosis treatment: a systematic review
Digital technologies are increasingly harnessed to support treatment of persons with tuberculosis (TB). Since in-person directly observed treatment (DOT) can be resource intensive and challenging to implement, these technologies may have the potential to improve adherence and clinical outcomes. We reviewed the effect of these technologies on TB treatment adherence and patient outcomes.
Pilot evaluation of a second-generation electronic pill box for adherence to Bedaquiline and antiretroviral therapy in drug-resistant TB/HIV co-infected patients in KwaZulu-Natal, South Africa
The introduction of Bedaquiline, the first new antimycobacterial drug in over 40 years, has highlighted the critical importance of medication adherence in drug-resistant tuberculosis (DR-TB) treatment to prevent amplified drug-resistance and derive sustained benefit. Real-time electronic dose monitoring (EDM) accurately measures adherence and allows for titration of adherence support for anti-retroviral therapy (ART). The goal of this study was to evaluate the accuracy and acceptability of a next-generation electronic pillbox (Wisepill RT2000) for Bedaquiline-containing TB regimens.
Opportunities to improve digital adherence technologies and TB care using human-centered design
Digital adherence technologies (DATs) have emerged as a promising means of supporting and supervising patients being treated for TB. However, despite considerable enthusiasm and wide-scale implementation, there has been variable uptake and engagement by patients and providers, and few clinical trials and programmatic data have demonstrated an improvement in treatment outcomes. Human-centered design (HCD) is a well-established methodology that utilizes qualitative research methods to understand the values and motivations of users, and systematically incorporates user input into the design or adaptation of products and interventions. We applied the HCD methodology to characterize adherence challenges facing TB patients and identified opportunities to adapt 99DOTS (a low-cost DAT) to better address these challenges.
Evaluating the potential costs and impact of digital health technologies for tuberculosis treatment support
Ensuring adherence and support during treatment of tuberculosis (TB) is a major public health challenge. Digital health technologies could help improve treatment outcomes. We considered their potential cost and impact on treatment for active or latent TB in Brazil.
An Inca trail to the Holy Grail: digital medication adherence support for TB care
We live in an era of effective drugs to treat TB, but these only work if taken consistently. The failure to take medication as prescribed, also referred to as ‘‘treatment non-adherence’’, is associated with significantly increased treatment failure, development of multidrug-resistant TB (MDR-TB), increased mortality and greater economic burden for TB patients and society. Fortunately, in this issue of the Journal, a research group from Peru has helped to guide our way forwards with publication of a TB adherence intervention study in Latin America. We will come to this study shortly, but first some background information to better understand the field.

We assessed the effectiveness of text messaging and medication monitors to improve medication adherence in TB patients.
Video-observed treatment for tuberculosis patients in Belarus: Findings from the first programmatic experience
Belarus, an upper-middle-income country in eastern Europe with a population of 9.5 million reports high levels of multidrug-resistant tuberculosis (resistance to rifampicin and isoniazid), which requires many patients to start long second-line treatment regimens each year: 1949 patients in 2015 alone. These patients need directly observed treatment daily due to the high risk of loss to treatment follow-up. Regular travel to treatment services incurs substantial effort, expense and time lost in transit for the patients. Among multidrug-resistant tuberculosis patients starting treatment in Belarus in 2013, 12% interrupted medication. The Ministry of Health of Belarus and its Republic Scientific and Practical Centre for Pulmonology and Tuberculosis are investing in digital technologies to further strengthen the national tuberculosis programme. We describe the recent introduction of VOT in Belarus.
