    Development and description of a theory-driven, evidence-based, complex intervention to improve adherence to treatment for tuberculosis in the UK: the IMPACT study
    (Informa UK Limited, 2023-11-27) Jones, Annie S. K.; Horne, Rob; White, Jacqui; Costello, Trish; Darvell, Marcia; Karat, Aaron S.; Kielmann, Karina; Stagg, Helen R.; Hill, Adam T.; Kunst, Heinke; Campbell, Colin N. J.; Lipman, Marc C. I.
    Background Tuberculosis (TB) has a significant treatment burden for patients, requiring at least six months of anti-TB treatment (ATT) with multiple medicines. Ensuring good adherence to ATT is central to global TB strategies, including those in high-income, low-TB incidence (HILI) settings. For adherence interventions to be successful and deliverable, they need to address the personal and environmental factors influencing patient and provider behaviour. Purpose This paper describes the application of theory and research evidence to inform the design process of the IMPACT manualised intervention to support ATT adherence for adults with TB disease in the United Kingdom (UK). It also provides a full description of the resulting intervention. Methods We synthesised findings from our formative research (qualitative and quantitative scoping reviews and patient and carer interviews) and supplemented these with clinic observations, a literature review, and healthcare provider interviews. Findings were mapped to the guiding theoretical framework (Perceptions and Practicalities Approach) which was operationalised to design the intervention components and content. An Intervention Development Group (IDG) of relevant stakeholders were consulted to adapt the intervention to local clinical settings. Results The pragmatic, deliverable components and content for the IMPACT intervention included: (1) an enhanced, structured, risk assessment to systematically identify risk factors for non-adherence plus locally-adapted guidance to mitigate these; and (2) patient educational materials (an animated video and interactive patient booklet) about TB and its treatment, to communicate the need for treatment and address common concerns. Conclusions Using a theory– and evidence– based approach incorporating stakeholder input, we have developed a multi-component, pragmatic, manualised intervention, which addresses patients’ personal barriers to adherence within local service resources to improve adherence to ATT within UK TB services.

    Relational dynamics of treatment behavior among individuals with tuberculosis in high-income countries: A scoping review
    (Dove Press, 2021-09-21) Arakelyan, Stella; Karat, Aaron S.; Jones, Annie S. K.; Vidal, Nicole L.; Stagg, Helen R.; Darvell, Marcia; Horne, Rob; Lipman, Marc C. I.; Kielmann, Karina
    Although tuberculosis (TB) incidence has significantly declined in high-income, low-incidence (HILI) countries, challenges remain in managing TB in vulnerable populations who may struggle to stay on anti-TB treatment (ATT). Factors associated with non-adherence to ATT are well-documented; however, adherence is often narrowly conceived as a fixed binary variable that places emphasis on individual agency and the act of taking medicines, rather than on the demands of being on treatment more broadly. Further, the mechanisms through which documented factors act upon the experience of ‘being on treatment’ are poorly understood. Adopting a relational approach that emphasizes the embeddedness of individuals within dynamic social, structural, and systems contexts, this scoping review aims to synthesize qualitative evidence on experiences of being on ATT and mechanisms through which socio-ecological factors influence adherence in HILI countries. Six electronic databases were searched for peer-reviewed literature published in English between January 1990 and May 2020. Additional studies were obtained by searching references and citations of included studies. Narrative synthesis was used to analyze qualitative data extracted from included studies. Of 28 included studies, the majority (86%) reported on health systems factors, followed by personal characteristics (82%), structural influences (61%), social factors (57%), and treatment-related factors (50%). Included studies highlighted three points that underpin a relational approach to ATT behavior: (1) individual motivation and capacity to take ATT is dynamic and intertwined with, rather than separate from, social, health systems, and structural factors; (2) individuals’ pre-existing experiences of health-seeking influenced their views on treatment and their ability to commit to long-term regular medicine-taking; and (3) social, cultural, and political contexts play an important role in mediating how specific factors work to support or hinder ATT adherence behavior in different settings. Based on our analysis, we suggest that person-centered clinical management of tuberculosis should (a) acknowledge the ways in which ATT both disrupts and is managed within the everyday lives of individuals with TB; (b) appreciate that circumstances and the support and resources that individuals can access may change over the course of treatment; and (c) display sensitivity towards context-specific social and cultural norms affecting individual and collective experiences of being on ATT.

    Determinants of non-adherence to anti-TB treatment in high income, low TB incidence settings: A scoping review
    (The Union, 2021-06-01) Jones, Annie; Bidad, Natalie; Horne, Rob; Stagg, Helen R.; Wurie, Fatima; Kielmann, Karina; Karat, Aaron S.; Kunst, Heinke; Campbell, Colin N. J.; Darvell, Marcia; Clarke, Amy Louise; Lipman, Marc
    Background Improving adherence to anti-tuberculosis (TB) treatment is a public health priority in high income, low incidence (HILI) regions. We conducted a scoping review to identify reported determinants of non-adherence in HILI settings.

    IMPACT study on intervening with a manualised package to achieve treatment adherence in people with tuberculosis: Protocol paper for a mixed-methods study, including a pilot randomised controlled trial
    (BMJ, 2019-12-17) Stagg, Helen R.; Abubakar, Ibrahim; Campbell, Colin N. J.; Copas, Andrew; Darvell, Marcia; Horne, Robert; Kielmann, Karina; Kunst, Heinke; Mandelbaum, Mike; Pickett, Elisha; Story, Alistair; Vidal, Nicole L.; Wurie, Fatima; Lipman, Marc
    Introduction Compared with the rest of the UK and Western Europe, England has high rates of the infectious disease tuberculosis (TB). TB is curable, although treatment is for at least 6 months and longer when disease is drug resistant. If patients miss too many doses (non-adherence), they may transmit infection for longer and the infecting bacteria may develop resistance to the standard drugs used for treatment. Non-adherence may therefore risk both their health and that of others. Within England, certain population groups are thought to be at higher risk of non-adherence, but the factors contributing to this have been insufficiently determined, as have the best interventions to promote adherence. The objective of this study was to develop a manualised package of interventions for use as part of routine care within National Health Services to address the social and cultural factors that lead to poor adherence to treatment for TB disease.
