RESUMO
BACKGROUND: The disability-adjusted life year (DALY), a key metric for health resource allocation, encompasses morbidity through disability weights. Widely used in tuberculosis cost-effectiveness analysis (CEAs), DALYs play a significant role in informing intervention adopt/reject decisions. This study reviews the values and consistency of disability weights applied in tuberculosis-related CEAs. METHODS: We conducted a systematic review using the Tufts CEA database, updated to July 2023 with searches in Embase, Scopus and PubMed. Eligible studies needed to have included a cost-per-DALY ratio, and additionally either evaluated a tuberculosis (TB) intervention or included tuberculosis-related weights. We considered all tuberculosis health states: with/without human immunodeficiency virus (HIV) coinfection, TB treatments and treatment side effects. Data were screened and extracted independently by combinations of two authors. FINDINGS: A total of 105 studies spanning 2002-2023 across 50 countries (mainly low- and middle-income countries) were extracted. Disability weights were sourced primarily from the Global Burden of Disease (GBD; 100/165; 61%), with 17 non-GBD studies additionally referenced, along with primary derivation. Inconsistencies in the utilisation of weights were evident: of the 100 usages of GBD-sourced weights, only in 47 instances (47%) had the weight value been explicitly specified with an appropriate up-to-date reference cited (constituting 28% of all weight usages, 47/165). Sensitivity analyses on weight values had been conducted in 30% of studies (31/105). Twelve studies did not clearly specify weights or their sources; nine further calculated DALYs without morbidity. The review suggests methodological gaps in current approaches for representing important aspects of TB, including TB-HIV coinfection, treatment, drug-resistance, extrapulmonary TB and psychological impacts. We propose a set of best practice recommendations. INTERPRETATION: There is a need for increased rigour in the application, sensitivity testing and reporting of TB disability weights. Furthermore, there appears a desire among researchers to reflect elements of the tuberculosis experience beyond those allowed for by GBD disability weights.
RESUMO
Background: In 2022, fewer than half of persons with tuberculosis (TB) had access to molecular diagnostic tests for TB due to their high costs. Studies have found that the use of artificial intelligence (AI) software for chest X-ray (CXR) interpretation and sputum specimen pooling can each reduce the cost of testing. We modeled the combination of both strategies to estimate potential savings in consumables that could be used to expand access to molecular diagnostics. Methods: We obtained Xpert testing and positivity data segmented into deciles by AI probability scores for TB from the community- and healthcare facility-based active case finding conducted in Bangladesh, Nigeria, Viet Nam, and Zambia. AI scores in the model were based on CAD4TB version 7 (Zambia) and qXR (all other countries). We modeled four ordinal screening and testing approaches involving AI-aided CXR interpretation to indicate individual and pooled testing. Setting a false negative rate of 5%, for each approach we calculated additional and cumulative savings over the baseline of universal Xpert testing, as well as the theoretical expansion in diagnostic coverage. Results: In each country, the optimal screening and testing approach was to use AI to rule out testing in deciles with low AI scores and to guide pooled vs individual testing in persons with moderate and high AI scores, respectively. This approach yielded cumulative savings in Xpert tests over baseline ranging from 50.8% in Zambia to 57.5% in Nigeria and 61.5% in Bangladesh and Viet Nam. Using these savings, diagnostic coverage theoretically could be expanded by 34% to 160% across the different approaches and countries. Conclusions: Using AI software data generated during CXR interpretation to inform a differentiated pooled testing strategy may optimize TB diagnostic test use, and could extend molecular tests to more people who need them. The optimal AI thresholds and pooled testing strategy varied across countries, which suggests that bespoke screening and testing approaches may be needed for differing populations and settings.

RESUMO
INTRODUCTION: The large reservoir of tuberculosis (TB) infections is one of the main reasons for the persistent incidence of TB. Accurate diagnostic tests are crucial to correctly identify and treat people with TB infection, which is vital to eliminate TB globally. The rdESAT-6 and rCFP-10 (Cy-Tb) injection ('Cy-Tb'), a TB-specific antigen skin test and STANDARD F TB-Feron FIA ('Standard F TB') measuring interferon-gamma by fluorescence immunoassay assay are two novel tools for the diagnosis of TB infection which offer advantages compared with current tests in low-resource settings and reduced costs to both health systems and TB-affected people. The proposed study aims to evaluate the diagnostic accuracy of these two new tests for TB infection diagnosis. METHODS AND ANALYSIS: This cross-sectional study aims to assess the diagnostic accuracy for TB infection of the Cy-Tb skin test and Standard F TB assay (investigational tests) compared with the QuantiFERON-TB Gold Plus (QFT-Plus) assay as the immunological reference standard. Three different cohorts of study participants will be recruited at the Vietnam National Lung Hospital: adults with bacteriologically confirmed pulmonary TB (n=100), household contacts of people with TB (n=200) and people without TB infection (n=50). All consenting participants will undergo simultaneous testing with Cy-Tb, Standard F TB and QFT-Plus. The primary endpoint is the diagnostic accuracy of the Cy-Tb skin test and Standard F TB assay, expressed as sensitivity and specificity against the reference standard. ETHICS AND DISSEMINATION: Ethical approval was granted by the Vietnam National Lung Hospital Institutional Review Board (65/23/CN-HDDD-BVPTU) and the Swedish Ethical Review Authority (Dnr 2023-04271-01). Study results will be disseminated to the scientific community and policymakers through scientific publications. TRIAL REGISTRATION NUMBER: NCT06221735.

BACKGROUND: Vietnam's primary mechanism of achieving sustainable funding for universal health coverage (UHC) and financial protection has been through its social health insurance (SHI) scheme. Steady progress towards access has been made and by 2020, over 90% of the population were enrolled in SHI. In 2022, as part of a larger transition towards the increased domestic financing of healthcare, tuberculosis (TB) services were integrated into SHI. This change required people with TB to use SHI for treatment at district-level facilities or to pay out of pocket for services. This study was conducted in preparation for this transition. It aimed to understand more about uninsured people with TB, assess the feasibility of enrolling them into SHI, and identify the barriers they faced in this process. METHODS: A mixed-method case study was conducted using a convergent parallel design between November 2018 and January 2022 in ten districts of Hanoi and Ho Chi Minh City, Vietnam. Quantitative data were collected through a pilot intervention that aimed to facilitate SHI enrollment for uninsured individuals with TB. Descriptive statistics were calculated. Qualitative interviews were conducted with 34 participants, who were purposively sampled for maximum variation. Qualitative data were analyzed through an inductive approach and themes were identified through framework analysis. Quantitative and qualitative data sources were triangulated. RESULTS: We attempted to enroll 115 uninsured people with TB into SHI; 76.5% were able to enroll. On average, it took 34.5 days to obtain a SHI card and it cost USD 66 per household. The themes indicated that a lack of knowledge, high costs for annual premiums, and the household-based registration requirement were barriers to SHI enrollment. Participants indicated that alternative enrolment mechanisms and greater procedural flexibility, particularly for undocumented people, is required to achieve full population coverage with SHI in urban centers. CONCLUSIONS: Significant addressable barriers to SHI enrolment for people affected by TB were identified. A quarter of individuals remained unable to enroll after receiving enhanced support due to lack of required documentation. The experience gained during this health financing transition is relevant for other middle-income countries as they address the provision of financial protection for the treatment of infectious diseases.

As we mark World TB Day 2024, we take this opportunity to reflect on the 2023 UN General Assembly High-Level Meeting (HLM) on the fight against tuberculosis-a milestone in the commitment towards a more coordinated, comprehensive approach to end tuberculosis globally. The UN HLM declaration on the fight against tuberculosis includes a specific pledge that all people with tuberculosis should receive a social benefits package to mitigate financial hardship. However, it is not known how this specific pledge will be realised and through which concrete actions. The use of the term financial hardship instead of WHO's key End TB Strategy indicator of catastrophic costs might prove challenging for robust evaluation of both the socioeconomic impact of tuberculosis and the effectiveness of socioeconomic support strategies to mitigate this impact. Moreover, in contrast to the financial pledges made for biomedical interventions, there was an absence of explicit investment in social protection. Such investments are imperative to facilitate successful expansion of social protection to meet the needs of people with tuberculosis and their households. Successful expansion of social protection is also dependent on political commitment and protected budgets from relevant stakeholders, including across government ministries. These strategies will help to ensure that the commitments on social protection made in the UN HLM declaration are turned into tangible actions with measurable effects.

Tuberculosis is recognised as a disease of the economically disadvantaged people due to its association with financial vulnerability. Mozambique still faces the challenge of the high burden of TB and associated costs. We aimed to understand the social and economic impacts of TB and the need for social support among people with TB in Mozambique. We conducted a qualitative study using a phenomenological approach focusing on the lived experiences and perceptions of people with TB. A total of 52 semi-structured one-to-one in-depth interviews were conducted and data were analysed using a reflexive thematic analysis. Three themes were drawn from the analysis: (i) TB has a social and economic impact that requires adaptation and resourcefulness amongst those affected; (ii) People with TB have different preferences and needs for social support, and (iii) People with TB have different knowledge of, and experiences with, formal social support. TB affects family and community relationships mainly due to impacts on the household's finances. People with TB in Mozambique are not entitled to any form of social support, and they need to rely on help from family and the community which is often insufficient. Further investigation is needed on how social support schemes can be developed in Mozambique.

Stigma towards people with tuberculosis (TB-Stigma) is associated with other psychosocial consequences of TB including mental illness and reduced quality of life (QoL). We evaluated TB-Stigma, depression, QoL, and the need for psychosocial support among adults with TB in Indonesia, a high TB burden country. In this primary health facility-based survey in seven provinces of Indonesia, from February to November 2022, we interviewed adults receiving (a) intensive phase treatment for drug-susceptible (DS) TB at public facilities, (b) treatment at private facilities, (c) those lost to follow up (LTFU) to treatment, and (d) those receiving TB retreatment. We used our previously validated Indonesian TB-Stigma Scale, Patient Health Questionnaire-9, and EQ-5D-5L to measure TB-Stigma, depression, and QoL. Additional questions assessed what psychosocial support was received or needed by participants. We recruited and interviewed 612 people, of whom 60.6% (96%CI 59.6-64.5%) experienced moderate TB-Stigma. The average TB-Stigma scores were 19.0 (SD 6.9; min-max 0-50; Form A-Patient Perspective) and 23.4 (SD 8.4, min-max 0-50; Form B-Community Perspective). The scores were higher among people receiving treatment at private facilities (adjusted B [aB] 2.48; 0.94-4.03), those LTFU (aB 2.86; 0.85-4.87), males (aB 1.73; 0.59-2.87), those losing or changing job due to TB (aB 2.09; 0.31-3.88) and those living in a rural area (aB 1.41; 0.19-2.63). Depression was identified in 41.5% (95% CI 37.7-45.3%) of participants. Experiencing TB-Stigma was associated with moderately severe to severe depression (adjusted odds ratio [aOR] 1.23; 1.15-1.32) and both stigma and depression were associated with lower QoL (aB -0.013; [-0.016]-[-0.010]). Informational (20.8%), emotional (25.9%) and instrumental (10.6%) support received from peers or peer-groups was limited, and unmet need for such support was high. There is a sizeable and intersecting burden of TB-Stigma and depression among adults with TB in Indonesia, which is associated with lower QoL. Participants reported a substantial unmet need for psychosocial support including peer-led mutual support groups. A community-based peer-led psychosocial support intervention is critical to defray the psychosocial impact of TB in Indonesia.
RESUMO
BACKGROUND: Globally, most people with multidrug-resistant tuberculosis (MDR-TB) and their households experience catastrophic costs of illness, diagnosis, and care. However, the factors associated with experiencing catastrophic costs are poorly understood. This study aimed to identify risk factors associated with catastrophic costs incurrence among MDR-TB-affected households in Ho Chi Minh City (HCMC), Viet Nam. METHODS: Between October 2020 and April 2022, data were collected using a locally-adapted, longitudinal WHO TB Patient Cost Survey in ten districts of HCMC. Ninety-four people with MDR-TB being treated with a nine-month TB regimen were surveyed at three time points: after two weeks of treatment initiation, completion of the intensive phase and the end of the treatment (approximately five and 10 months post-treatment initiation respectively). The catastrophic costs threshold was defined as total TB-related costs exceeding 20% of annual pre-TB household income. Logistic regression was used to identify variables associated with experiencing catastrophic costs. A sensitivity analysis examined the prevalence of catastrophic costs using alternative thresholds and cost estimation approaches. RESULTS: Most participants (81/93 [87%]) experienced catastrophic costs despite the majority 86/93 (93%) receiving economic support through existing social protection schemes. Among participant households experiencing and not experiencing catastrophic costs, median household income was similar before MDR-TB treatment. However, by the end of MDR-TB treatment, median household income was lower (258 [IQR: 0-516] USD vs. 656 [IQR: 462-989] USD; p = 0.003), and median income loss was higher (2838 [IQR: 1548-5418] USD vs. 301 [IQR: 0-824] USD; p < 0.001) amongst the participant households who experienced catastrophic costs. Being the household's primary income earner before MDR-TB treatment (aOR = 11.2 [95% CI: 1.6-80.5]), having a lower educational level (aOR = 22.3 [95% CI: 1.5-344.1]) and becoming unemployed at the beginning of MDR-TB treatment (aOR = 35.6 [95% CI: 2.7-470.3]) were associated with experiencing catastrophic costs. CONCLUSION: Despite good social protection coverage, most people with MDR-TB in HCMC experienced catastrophic costs. Incurrence of catastrophic costs was independently associated with being the household's primary income earner or being unemployed. Revision and expansion of strategies to mitigate TB-related catastrophic costs, in particular avoiding unemployment and income loss, are urgently required.

Variability in case severity and in the range of symptoms experienced has been apparent from the earliest months of the COVID-19 pandemic. From a clinical perspective, symptom variability might indicate various routes/mechanisms by which infection leads to disease, with different routes requiring potentially different treatment approaches. For public health and control of transmission, symptoms in community cases were the prompt upon which action such as PCR testing and isolation was taken. However, interpreting symptoms presents challenges, for instance, in balancing the sensitivity and specificity of individual symptoms with the need to maximise case finding, whilst managing demand for limited resources such as testing. For both clinical and transmission control reasons, we require an approach that allows for the possibility of distinct symptom phenotypes, rather than assuming variability along a single dimension. Here we address this problem by bringing together four large and diverse datasets deriving from routine testing, a population-representative household survey and participatory smartphone surveillance in the United Kingdom. Through the use of cutting-edge unsupervised classification techniques from statistics and machine learning, we characterise symptom phenotypes among symptomatic SARS-CoV-2 PCR-positive community cases. We first analyse each dataset in isolation and across age bands, before using methods that allow us to compare multiple datasets. While we observe separation due to the total number of symptoms experienced by cases, we also see a separation of symptoms into gastrointestinal, respiratory and other types, and different symptom co-occurrence patterns at the extremes of age. In this way, we are able to demonstrate the deep structure of symptoms of COVID-19 without usual biases due to study design. This is expected to have implications for the identification and management of community SARS-CoV-2 cases and could be further applied to symptom-based management of other diseases and syndromes.

Background: Tuberculosis (TB) is a leading cause of death due to infectious disease worldwide. People with TB and their households often suffer social and economic losses due to the cost of tuberculosis care. The World Health Organization 2015 End TB strategy called for socioeconomic support through social protection interventions. Social protection has the potential to enable people with TB and their households to break the cycle of TB and poverty, thereby improving both treatment and socioeconomic outcomes. This study aims to evaluate whether people with TB who are recipients of social protection interventions have better treatment and socioeconomic outcomes than those who are not recipients of social protection interventions. Methods: We will systematically review literature published in English between 2012 and 2021 from PubMed, Embase, and Web of Science, and grey literature from Google Scholar and selected, relevant databases. We will include studies that describe a social protection intervention (as defined by the World Bank) and report on TB treatment outcomes and/or socioeconomic outcomes. We will only include studies pertaining to populations in low-and-middle-income countries and/or countries with high TB burden. We will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Study quality will be assessed using the Cochrane Risk of Bias for randomized controlled trials and the Newcastle Ottawa Scale for non-randomised controlled studies. If sufficient quantitative data are available, we will perform a meta-analysis of aggregated outcomes. Lastly, we will use the Grading Recommendations Assessment, Development, and Evaluation to describe the overall quality of evidence. Ethics and dissemination: Ethical approval is not required for this systematic review, as all data extraction and analysis will be conducted on published documents. We will disseminate this protocol through conference presentations. The systematic review has been registered prospectively in the PROSPERO database (registration number CRD42022382181).
RESUMO
OBJECTIVE: People with tuberculosis (TB) and their households face severe socioeconomic consequences, which will only be mitigated by intersectoral collaboration, especially between the health and social sectors. Evidence suggests that key factors for successful collaboration include shared goals, trust, commitment, resource allocation, efficient processes and effective communication and motivation among collaborating parties. This study aimed to understand healthcare and social support sector policymakers' perspectives on potential solutions to mitigate financial impact among people with TB and their households in Mozambique. DESIGN: Qualitative study with primary data collection through one-to-one in-depth interviews. SETTING: Gaza and Inhambane provinces, Mozambique. PARTICIPANTS: Policymakers in the health and social support sector. RESULTS: A total of 27 participants were purposefully sampled. Participants were asked about their perspectives on TB-related financial impact and potential solutions to mitigate such impact. Participants reported that people with TB are not explicitly included in existing social support policies because TB per se is not part of the eligibility criteria. People with TB and underweight or HIV were enrolled in social support schemes providing food or cash. Two themes were generated from the analysis: (1) Policymakers suggested several mitigation solutions, including food and monetary support, but perceived that their implementation would be limited by lack of resources; and (2) lack of shared views or processes related to intersectoral collaboration between health and social support sector hinders design and implementation of social support for people with TB. CONCLUSION: Despite health and social sector policymakers reporting a willingness for intersectoral collaboration to mitigate TB-related financial impact, current approaches were perceived to be unilateral. Collaboration between health and social support sectors should focus on improving existing social support programmes.

BACKGROUND: The World Health Organization (WHO) recommends the diagnosis of tuberculosis (TB) using molecular tests, such as Xpert MTB/RIF (MTB/RIF) or Xpert Ultra (Ultra). These tests are expensive and resource-consuming, and cost-effective approaches are needed for greater coverage. METHODS: We evaluated the cost-effectiveness of pooling sputum samples for TB testing by using a fixed amount of 1,000 MTB/RIF or Ultra cartridges. We used the number of people with TB detected as the indicator for cost-effectiveness. Cost-minimization analysis was conducted from the healthcare system perspective and included the costs to the healthcare system using pooled and individual testing. RESULTS: There was no significant difference in the overall performance of the pooled testing using MTB/RIF or Ultra (sensitivity, 93.9% vs. 97.6%, specificity 98% vs. 97%, p-value > 0.1 for both). The mean unit cost across all studies to test one person was 34.10 international dollars for the individual testing and 21.95 international dollars for the pooled testing, resulting in a savings of 12.15 international dollars per test performed (35.6% decrease). The mean unit cost per bacteriologically confirmed TB case was 249.64 international dollars for the individual testing and 162.44 international dollars for the pooled testing (34.9% decrease). Cost-minimization analysis indicates savings are directly associated with the proportion of samples that are positive. If the TB prevalence is ≥ 30%, pooled testing is not cost-effective. CONCLUSION: Pooled sputum testing can be a cost-effective strategy for diagnosis of TB, resulting in significant resource savings. This approach could increase testing capacity and affordability in resource-limited settings and support increased testing towards achievement of WHO End TB strategy.

INTRODUCTION: Tuberculosis (TB) remains a highly stigmatised disease that can cause or exacerbate mental health disorders. Despite increased awareness of the importance of reducing TB stigma, validated tools to measure TB stigma remain scarce. This study aimed to culturally adapt and validate the Van Rie TB Stigma Scale in Indonesia, a country with the second largest TB incidence worldwide. METHODS: We validated the scale in three phases: translation, cultural adaptation, and psychometric evaluation. We invited diverse experts to an interdisciplinary panel for the cross-cultural adaptation, then performed a psychometric evaluation of the scale: exploratory and confirmatory factor analyses, reliability analysis, and correlation analysis with Patient Health Questionnaire 9 [PHQ-9]. RESULTS: We culturally adapted the original scale's language and content during the translation and cultural adaptation phases. After psychometric evaluation with 401 participants in seven provinces of Indonesia, we removed two items. The new scale had two forms: (A) patient and (B) community perspective forms. Both forms had good internal consistency, with respective Cronbach's alpha values of 0.738 and 0.807. We identified three loading factors in Form A (disclosure, isolation, and guilty) and two loading factors in Form B (isolation and distancing). The scale showed correlation with PHQ-9 (Form A, rs = 0.347, p < 0.001; Form B, rs = 0). CONCLUSIONS: The culturally adapted Indonesian version of Van Rie's TB Stigma Scale is comprehensive, reliable, internally consistent, and valid. The scale is now ready for applied scale-up in research and practice to measure TB-stigma and evaluate the impact of TB-stigma reduction interventions in Indonesia.

BACKGROUND: Over 500 million people live with chronic respiratory diseases globally and approximately 4 million of these, mostly from the low- and middle-income countries including sub-Saharan Africa, die prematurely every year. Despite high CRD morbidity and mortality, only very few studies describe CRDs and little is known about the economic, social and psychological dimensions of living with CRDs in sub-Saharan Africa. We aimed to gain an in-depth understanding of the social, livelihood and psychological dimensions of living with CRD to inform management of CRDs in Sudan and Tanzania. METHOD: We conducted 12 in-depth interviews in 2019 with people with known or suspected CRD and 14 focus group discussions with community members in Gezira state, Sudan and Dodoma region, Tanzania, to share their understanding and experience with CRD. The data was analysed using thematic framework analysis. RESULTS: People with CRD in both contexts reported experiences under two broad themes: impact on economic wellbeing and impact on social and psychological wellbeing. Capacity to do hard physical work was significantly diminished, resulting in direct and indirect economic impacts for them and their families. Direct costs were incurred while seeking healthcare, including expenditures on transportation to health facility and procurement of diagnostic tests and treatments, whilst loss of working hours and jobs resulted in substantial indirect costs. Enacted and internalised stigma leading to withdrawal and social exclusion was described by participants and resulted partly from association of chronic cough with tuberculosis and HIV/AIDS. In Sudan, asthma was described as having negative impact on marital prospects for young women and non-disclosure related to stigma was a particular issue for young people. Impaired community participation and restrictions on social activity led to psychological stress for both people with CRD and their families. CONCLUSION: Chronic respiratory diseases have substantial social and economic impacts among people with CRD and their families in Sudan and Tanzania. Stigma is particularly strong and appears to be driven partly by association of chronic cough with infectiousness. Context-appropriate measures to address economic impacts and chronic cough stigma are urgently needed as part of interventions for chronic respiratory diseases in these sub-Saharan African contexts.

BACKGROUND: It is well known that poverty is associated with ill health and that ill health can result in direct and indirect costs that can perpetuate poverty. Social protection, which includes policies and programmes intended to prevent and reduce poverty in times of ill health, could be one way to break this vicious cycle. Social protection, particularly cash transfers, also has the potential to promote healthier behaviours, including healthcare seeking. Although social protection, particularly conditional and unconditional cash transfers, has been widely studied, it is not well known how recipients experience social protection interventions, and what unintended effects such interventions can cause. OBJECTIVES: The aim of this review was to explore how conditional and unconditional cash transfer social protection interventions with a health outcome are experienced and perceived by their recipients. SEARCH METHODS: We searched Epistemonikos, MEDLINE, CINAHL, Social Services Abstracts, Global Index Medicus, Scopus, AnthroSource and EconLit from the start of the database to 5 June 2020. We combined this with reference checking, citation searching, grey literature and contact with authors to identify additional studies. We reran all strategies in July 2022, and the new studies are awaiting classification. SELECTION CRITERIA: We included primary studies, using qualitative methods or mixed-methods studies with qualitative research reporting on recipients' experiences of cash transfer interventions where health outcomes were evaluated. Recipients could be adult patients of healthcare services, the general adult population as recipients of cash targeted at themselves or directed at children. Studies could be evaluated on any mental or physical health condition or cash transfer mechanism. Studies could come from any country and be in any language. Two authors independently selected studies. DATA COLLECTION AND ANALYSIS: We used a multi-step purposive sampling framework for selecting studies, starting with geographical representation, followed by health condition, and richness of data. Key data were extracted by the authors into Excel. Methodological limitations were assessed independently using the Critical Appraisal Skills Programme (CASP) criteria by two authors. Data were synthesised using meta-ethnography, and confidence in findings was assessed using the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach. MAIN RESULTS: We included 127 studies in the review and sampled 41 of these studies for our analysis. Thirty-two further studies were found after the updated search on 5 July 2022 and are awaiting classification. The sampled studies were from 24 different countries: 17 studies were from the African region, seven were from the region of the Americas, seven were from the European region, six were from the South-East Asian region, three from the Western Pacific region and one study was multiregional, covering both the African and the Eastern Mediterranean regions. These studies primarily explored the views and experiences of cash transfer recipients with different health conditions, such as infectious diseases, disabilities and long-term illnesses, sexual and reproductive health, and maternal and child health. Our GRADE-CERQual assessment indicated we had mainly moderate- and high-confidence findings. We found that recipients perceived the cash transfers as necessary and helpful for immediate needs and, in some cases, helpful for longer-term benefits. However, across conditional and unconditional programmes, recipients often felt that the amount given was too little in relation to their total needs. They also felt that the cash alone was not enough to change their behaviour and, to change behaviour, additional types of support would be required. The cash transfer was reported to have important effects on empowerment, autonomy and agency, but also in some settings, recipients experienced pressure from family or programme staff on cash usage. The cash transfer was reported to improve social cohesion and reduce intrahousehold tension. However, in settings where some received the cash and others did not, the lack of an equal approach caused tension, suspicion and conflict. Recipients also reported stigma in terms of cash transfer programme assessment processes and eligibility, as well as inappropriate eligibility processes. Across settings, recipients experienced barriers in accessing the cash transfer programme, and some refused or were hesitant to receive the cash. Some recipients found cash transfer programmes more acceptable when they agreed with the programme's goals and processes. AUTHORS' CONCLUSIONS: Our findings highlight the impact of the sociocultural context on the functioning and interaction between the individual, family and cash transfer programmes. Even where the goals of a cash transfer programme are explicitly health-related, the outcomes may be far broader than health alone and may include, for example, reduced stigma, empowerment and increased agency of the individual. When measuring programme outcomes, therefore, these broader impacts could be considered for understanding the health and well-being benefits of cash transfers.

Tuberculosis (TB) and poverty are inextricably linked. Catastrophic costs of TB illness drive TB-affected households into worsening impoverishment and hamper treatment success. The WHO's End TB Strategy recommends social protection for TB-affected households to mitigate financial shock and improve TB outcomes. This scoping review maps the landscape of social protection interventions for people with TB and their households in low- and middle-income countries with high TB burden. A systematic search of Medline, Embase, PubMed, and Web of Science for relevant articles was performed, supplemented with a gray literature search of key databases. Articles were included if they described social protection available to people with TB and TB-affected households in a low- or middle-income country. Data were synthesized in tabular form, and descriptive narrative outlined the successes and challenges of the social protection interventions identified. The search identified 33,360 articles. After abstract screening, 74 articles underwent full text screening, and 49 were included in the final analysis. Forty-three types of social protection were identified, of which 24 were TB specific (i.e., only people with TB were eligible). Varying definitions were used to describe similar social protection interventions, which limited cross-study comparison. Intervention successes included acceptability and increased financial autonomy among recipients. Challenges included delays in intervention delivery and unexpected additional bank transfer fees. A wide range of acceptable social protection interventions are available, with cash transfer schemes predominating. Use of standardized definitions of social protection interventions would facilitate consolidation of evidence and enhance design and implementation in future.

Workers with tuberculosis (TB) are often stigmatized, negatively impacting their socioeconomic position, mental health, and TB treatment outcomes. There is a dearth of validated tools to assess stigma in the worker population. This study aimed to develop and validate a novel, culturally adapted tool to measure TB-related stigma among workers in Indonesia. We translated, adapted, applied, and internally validated Van Rie's TB-Stigma Scale to the worker population in varying sizes businesses (formal and informal business sectors) in Indonesia. Psychometric evaluation using exploratory and confirmatory factor analyses (EFA and CFA) was performed to check the tool's internal consistency and reliability. The translation and cultural adaptation phases resulted in a final 11-item tool. From 172 participant responses, the EFA found two loading factors relating to responses on isolation and exclusion from the workplace. The CFA confirmed that the developed model had moderate fit with R2 values for each item ranging from 0.37 to 0.84. The tool was reliable (Cronbach's alpha 0.869). This validated, consistent and reliable adapted tool is ready to use in larger scale evaluations of TB-related stigma amongst workers in formal and informal business sectors of Indonesia to develop strategies to eliminate TB-related stigma from the workplace.
RESUMO
INTRODUCTION: Undernutrition is a major risk factor for tuberculosis (TB), which is estimated to be responsible for 1.9 million TB cases per year globally. The effectiveness of micronutrient supplementation on TB treatment outcomes and its prognostic markers (sputum conversion, serum zinc, retinol and haemoglobin levels) has been poorly understood. This study aimed to determine the effect of zinc and vitamin A supplementation on prognostic markers and TB treatment outcomes among adults with sputum-positive pulmonary TB. METHODS: A systematic literature search for randomised controlled trials (RCTs) was performed in PubMed, Embase and Scopus databases. Meta-analysis with a random effect model was performed to estimate risk ratio (RR) and mean difference (MD), with a 95% CI, for dichotomous and continuous outcomes, respectively. RESULTS: Our search identified 2195 records. Of these, nine RCTs consisting of 1375 participants were included in the final analyses. Among adults with pulmonary TB, zinc (RR: 0.94, 95% CI: 0.86 to 1.03), vitamin A (RR: 0.90, 95% CI: 0.80 to 1.01) and combined zinc and vitamin A (RR: 0.98, 95% CI: 0.89 to 1.08) supplementation were not significantly associated with TB treatment success. Combined zinc and vitamin A supplementation was significantly associated with increased sputum smear conversion at 2 months (RR: 1.16, 95% CI: 1.03 to 1.32), serum zinc levels at 2 months (MD: 0.86 µmol/L, 95% CI: 0.14 to 1.57), serum retinol levels at 2 months (MD: 0.06 µmol/L, 95% CI: 0.04 to 0.08) and 6 months (MD: 0.12 µmol/L, 95% CI: 0.10 to 0.14) and serum haemoglobin level at 6 months (MD: 0.29 µg/dL, 95% CI: 0.08 to 0.51), among adults with pulmonary TB. CONCLUSIONS: Providing zinc and vitamin A supplementation to adults with sputum-positive pulmonary TB during treatment may increase early sputum smear conversion, serum zinc, retinol and haemoglobin levels. However, the use of zinc, vitamin A or both was not associated with TB treatment success. PROSPERO REGISTRATION NUMBER: CRD42021248548.
