Abstract
Introduction: Globally, tuberculosis (TB) remains one of the leading infectious causes of death, with 1.3 million deaths. Digital adherence technologies (DATs) have the potential to provide person-centred care and improve outcomes. Using the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) framework, we conducted a scoping review of DAT implementations for TB treatment.
Methods: We searched seven databases for papers published between January 2000 and April 2023, using keywords for 'tuberculosis' and 'digital adherence technology'. Articles meeting prespecified inclusion criteria and containing data on RE-AIM domains were included. We defined 'reach' as comprising cellphone ownership and engagement by people with TB (PWTB) with DATs, 'adoption' as engagement by healthcare providers with DAT programmes, 'implementation' as the fidelity of the DAT programme implemented and 'maintenance' as longer-term uptake of DATs.
Results: Of 10 313 records, 102 contributed to the synthesis. DATs included short message service (SMS), phone, 99DOTS, video-supported therapy (VST) and pillboxes. For 'reach', across various settings, cellphone access varied from 50%-100% and 2%-31% of PWTB was excluded from accessing DATs due to technology challenges. 36%-100% of PWTB agreed to use a DAT. The weighted mean of DAT engagement over dose-days was 81% for SMS, 85% for phone, 61% for 99DOTS, 87% for pillbox and 82% for VST. Concerning 'implementation', the fidelity of DAT implementations was affected by technological issues such as cellphone coverage, DAT malfunction and provider-facing issues, including failure to initiate intensified patient management following low DAT engagement. Findings related to RE-AIM dimensions of 'adoption' and 'maintenance' were limited.
Conclusion: Our findings suggest that the 'reach' of DATs may be limited by a cascade of barriers, including limitations in cellphone accessibility and suboptimal sustained DAT engagement by PWTB. Video and pillbox DATs have higher levels of engagement. Implementation challenges included technological and provider-facing issues. Improving implementation outcomes may be important for TB DATs to achieve a broader public health impact.
期刊介绍：
BMJ Global Health is an online Open Access journal from BMJ that focuses on publishing high-quality peer-reviewed content pertinent to individuals engaged in global health, including policy makers, funders, researchers, clinicians, and frontline healthcare workers. The journal encompasses all facets of global health, with a special emphasis on submissions addressing underfunded areas such as non-communicable diseases (NCDs). It welcomes research across all study phases and designs, from study protocols to phase I trials to meta-analyses, including small or specialized studies. The journal also encourages opinionated discussions on controversial topics.
