Lessons for TB from the COVID-19 response: qualitative data from Brazil, India and South Africa.

BACKGROUND: Brazil, India and South Africa are among the top 30 high TB burden countries globally and experienced high rates of SARS-CoV-2 infection and mortality. The COVID-19 response in each country was unprecedented and complex, informed by distinct political, economic, social and health systems contexts. While COVID-19 responses have set back TB control efforts, they also hold lessons to inform future TB programming and services. METHODS: This was a qualitative exploratory study involving interviews with TB stakeholders (n = 76) in Brazil, India and South Africa 2 years into the COVID-19 pandemic. Interview transcripts were analysed using an inductive coding strategy. RESULTS: Political will - whether national or subnational - enabled implementation of widespread prevention measures during the COVID-19 response in each country and stimulated mobile and telehealth service delivery innovations. Participants in all three countries emphasised the importance of mobilising and engaging communities in public health responses and noted limited health education and information as barriers to implementing TB control efforts at the community level. CONCLUSIONS: Building political will and social mobilisation must become more central to TB programming. COVID-19 has shown this is possible. A similar level of investment and collaborative effort, if not greater, as that seen during the COVID-19 pandemic is needed for TB through multi-sectoral partnerships.

CONTEXTE: Le Brésil, l'Inde et l'Afrique du Sud figurent parmi les 30 pays les plus touchés par la TB dans le monde et ont connu des taux élevés d'infection et de mortalité dus au SARS-CoV-2. La réponse au COVID-19 dans chacun de ces pays a été sans précédent et complexe, en raison de contextes politiques, économiques, sociaux et de systèmes de santé distincts. Si les réponses au COVID-19 ont fait reculer les efforts de lutte contre la TB, elles permettent également de tirer des enseignements pour les futurs programmes et services de lutte contre la TB. MÉTHODES: Il s'agit d'une étude exploratoire qualitative comprenant des entretiens avec des acteurs de la lutte contre la TB (n = 76) au Brésil, en Inde et en Afrique du Sud, 2 ans après le début de la pandémie de COVID-19. Les transcriptions des entretiens ont été analysées à l'aide d'une stratégie de codage inductive. RÉSULTATS: La volonté politique ­ qu'elle soit nationale ou infranationale ­ a permis la mise en œuvre de mesures de prévention généralisées au cours de la riposte au COVID-19 dans chaque pays et a stimulé les innovations en matière de prestation de services mobiles et de télésanté. Les participants des trois pays ont souligné l'importance de la mobilisation et de l'engagement des communautés dans les réponses de santé publique et ont noté que l'éducation et l'information sanitaires limitées constituaient des obstacles à la mise en œuvre des efforts de lutte contre la TB au niveau communautaire. CONCLUSIONS: La volonté politique et la mobilisation sociale doivent occuper une place plus centrale dans les programmes de lutte contre la TB. La conférence COVID-19 a montré que c'était possible. Un niveau d'investissement et de collaboration similaire, voire supérieur, à celui observé lors de la pandémie de COVID-19 est nécessaire pour lutter contre la TB par le biais de partenariats multisectoriels.

TB programme stakeholder views on lessons from the COVID-19 response in South Africa.

BACKGROUND: The global COVID-19 pandemic has reversed many of the hard-won gains made in TB programmes and the associated reduction in the number of TB deaths, case notifications and incidence over the last three decades. Modelling estimates show that the impact will be lasting. There are global calls to recover the shortfalls along the TB care cascade that have resulted from COVID-19, with the recognition that the COVID-19 response holds lessons to inform more robust and comprehensive TB programmes and services. OBJECTIVE: To explore lessons from response measures to the COVID-19 pandemic in two high TB burden South African provinces. DESIGN: This was an exploratory qualitative study. We conducted interviews with TB programme stakeholders (managers and facility-level staff: n = 35) between February and June 2022. RESULTS: We identified eight facilitators of the COVID-19 response, including political will, rapid policy development, multi-sectoral collaboration, patient-centred models of care delivery, community engagement, mHealth and telehealth technologies, rigorous contact tracing and widespread mask wearing. Political will was singled out as a critical driver of the response. CONCLUSION: Leveraging COVID-19 inspired collaborations, technologies and avenues for health service delivery is an opportunity to maximise benefits for the TB programme. Reinvestment in national TB programmes and political prioritisation of TB are critical.

CONTEXTE: La pandémie mondiale de COVID-19 a réduit à néant une grande partie des gains durement acquis dans les programmes de lutte contre la TB et la réduction associée du nombre de décès dus à la TB, de notifications de cas et d'incidence au cours des trois dernières décennies. Les estimations de la modélisation montrent que l'impact sera durable. Des appels ont été lancés au niveau mondial pour combler les lacunes dans la chaîne de soins de la TB qui ont résulté de la pandémie de COVID-19, en reconnaissant que la réponse à cette pandémie est porteuse d'enseignements qui permettront d'élaborer des programmes et des services de lutte contre la TB plus solides et plus complets. OBJECTIF: Etudier les enseignements tirés des mesures prises en réponse à la pandémie de COVID-19 dans deux provinces sud-africaines à forte charge de morbidité TB. MÉTHODE: Il s'agit d'une étude qualitative exploratoire. Nous avons mené des entretiens avec les parties prenantes des programmes de lutte contre la TB (responsables et personnel au niveau des établissements : n = 35) entre février et juin 2022. RÉSULTATS: Nous avons identifié huit facilitateurs de la riposte au COVID-19, notamment la volonté politique, l'élaboration rapide de directives, la collaboration multisectorielle, les modèles de prestation de soins centrés sur le patient, l'engagement communautaire, les technologies de mHealth et de télésanté, la recherche rigoureuse des contacts et le port généralisé de masques. La volonté politique a été désignée comme un moteur essentiel de la riposte. CONCLUSION: L'exploitation des collaborations, des technologies et des moyens inspirés du COVID-19 pour la prestation de services de santé est une occasion de maximiser les avantages pour le programme de lutte contre la TB. Il est essentiel de réinvestir dans les programmes nationaux de lutte contre la TB et d'en faire une priorité politique.

Children´s priorities to improve the acceptability of MDR-TB treatment: qualitative data from South Africa.

BACKGROUND: Multidrug-resistant TB (MDR-TB) treatment for children frequently includes unpalatable drugs with low overall acceptability. This can negatively impact children and their caregivers´ treatment experiences and is an important contributor to poor adherence, and potentially, poor treatment outcomes. Children and their caregivers´ preferences for MDR-TB treatment are not well documented. We describe children and caregivers´ priorities to inform future MDR-TB treatment regimens.METHODS: We conducted a cross-sectional qualitative study at a TB hospital in South Africa using semi-structured interviews and participatory research activities with caregivers and children routinely diagnosed and treated for MDR-TB between June and August 2018.RESULTS: We conducted 15 interviews with children and their caregivers. Children ranged from 2 to 17 years of age (median age: 8.3 years). Children and caregivers had an overall negative experience of MDR-TB treatment. Children and caregivers described how future MDR-TB drugs and regimens should prioritise sweeter flavours, fewer pills, brighter colours, and formulations that are easy to prepare and administer and dispensed in colourful, small and discrete packaging.CONCLUSIONS: MDR-TB treatment acceptability remains low, and negatively impacts children and their caregivers´ treatment experiences. Improving the overall acceptability of MDR-TB treatment requires engaging with children and their caregivers to better understand their priorities for new treatment regimens and child-friendly formulations.

TB preventive therapy preferences among children and adolescents.

BACKGROUND: TB preventive therapy (TPT) is critical for ending TB, yet implementation remains poor. With new global guidelines expanding TPT eligibility and regimens, we aimed to understand TPT preferences among children, adolescents and caregivers.METHODS: We undertook a discrete choice experiment among 131 children, 170 adolescents and 173 caregivers, and conducted 17 in-depth interviews in 25 clinics in Cape Town, South Africa. The design included attributes for location, waiting time, treatment duration, dosing frequency, formulation/size, side effects, packaging and taste. Mixed-effects logistic regression models were used for analysis.RESULTS: Among children and caregivers, the number and size of pills, taste and side effects were important drivers of preferences. Among adolescents and caregivers, clinic waiting times and side effects were significant drivers of preferences. Adolescents expressed concerns about being stigmatised, and preferred services from local clinics to services delivered in the community. Dosing frequency and treatment duration were only significant drivers of choice among adolescents, and only if linked to fewer clinic visits.CONCLUSIONS: Introducing shorter TPT regimens in isolation without consideration of preferences and health services may not have the desired effect on uptake and completion. Developing TPT delivery models and formulations that align with preferences must be prioritised.

Persistent chronic respiratory symptoms despite TB cure is poorly correlated with lung function.

BACKGROUND: Persistent respiratory symptoms and lung function deficits are common after patients with TB. We aimed to define the burden of post-TB lung disease (PTLD) and assess associations between symptoms and impairment in two high TB incidence communities.METHODS: This was a cross-sectional survey of adults in Cape Town, South Africa who completed TB treatment 1-5 years previously. Questionnaires, spirometry and 6-minute walking distance (6MWD) were used to assess relationships between outcome measures and associated factors.RESULTS: Of the 145 participants recruited (mean age: 42 years, range: 18-75; 55 [38%] women), 55 (38%) had airflow obstruction and 84 (58%) had low forced vital capacity (FVC); the mean 6MWD was 463 m (range: 240-723). Respiratory symptoms were common: chronic cough (n = 27, 19%), wheeze (n = 61, 42%) and dyspnoea (modified MRC dyspnoea score 3 or 4: n = 36, 25%). There was poor correlation between FVC or obstruction and 6MWD. Only low body mass index showed consistent association with outcomes on multivariable analyses. Only 19 (13%) participants had a diagnosis of respiratory disease, and 16 (11%) currently received inhalers.CONCLUSION: There was substantial burden of symptoms and physiological impairment in this "cured" population, but poor correlation between objective outcome measures, highlighting deficits in our understanding of PTLD.

Acceptability of a first-line anti-tuberculosis formulation for children: qualitative data from the SHINE trial.

SETTING: We conducted a qualitative exploration into the palatability and acceptability of a novel fixed-dose combination (FDC) anti-tuberculosis drug. This study was nested in the SHINE (Shorter treatment for minimal TB in children) trial, which compares the safety and efficacy of treating non-severe drug-susceptible tuberculosis (TB) with a 6 vs. 4 months anti-tuberculosis regimen in children aged 0-16 years. Participants were recruited in Cape Town, South Africa.OBJECTIVE: To describe the palatability and acceptability of a FDC of rifampicin, isoniazid and pyrazinamide among South African children and their caregivers in the SHINE trial.METHODS: We conducted 20 clinic observations of treatment administration, during which we conducted 16 semi-structured interviews with children and their caregivers. Data were organised thematically to report on experiences with administering and ingesting the FDC.RESULTS: Children and caregivers' experiences varied from delight to disgust. In general, participants said that the FDC compared favourably to other formulations. Pragmatic challenges such as dissolving the FDC and the time required to administer the FDC impeded caregivers' ability to integrate treatment into their daily routines. Drug manipulation was common among caregivers to improve TB treatment administration.CONCLUSION: This novel FDC appears acceptable for children, albeit with practical challenges to administration. Scale-up of FDC use should include supplementary intervention components to support caregivers.
