Towards universal health coverage in Vietnam: a mixed-method case study of enrolling people with tuberculosis into social health insurance.

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.

Cash transfers to enhance completion of TB screening among household contacts in rural Tanzania.

Tanzanian TB guidelines recommend facility-based TB screening for symptomatic household contacts (HHCs) or those aged <5 years, but cost remains a major barrier. In this study, we evaluate the use of unconditional cash transfers (UCTs) to facilitate completion of HHC TB screening.In this prospective interventional study, we enrolled index people diagnosed with TB (PWTB) within 8 weeks of TB treatment initiation from the TB clinic at Haydom Lutheran Hospital, Haydom, Tanzania, and surrounding TB dispensaries in rural Tanzania. The study provided at the time of enrollment an UCT up to 40,000 Tanzanian shillings (USD16.91) directly to heads of households with PWTB, covered medical costs from screening activities and provided three bi-weekly phone reminders to facilitate HHC TB screening. The primary outcome was TB screening completion for all HHCs compared to the same period of the preceding year.We enrolled 120 index PWTB, including 398 HHCs between July and December 2022. The median age for index PWTB was 35 years; 38% were females. Sixty-five (54%) households completed screening for all HHCs, compared to 7% during the same period of the preceding year.These interventions may considerably improve completion of HHC TB screening in rural Tanzania..

Strategies to resolve the gap in adolescent tuberculosis care at four health facilities in Uganda: The teenager's TB pilot project.

In 2021, an estimated 10.6 million people fell ill with tuberculosis (TB) globally and 11.3% were children. About 40% of children aged five to fourteen years with TB are missed annually. In Uganda, 44% of adolescents with chronic cough of more than two weeks do not seek care from health facilities. Therefore, strategies to promote health care-seeking behaviour among adolescents were urgently needed to resolve the gap. In regard to this, the research project utilized a before and after design, in which the number of adolescents (10-19years) enrolled in the project health facilities were compared before and after the intervention. The intervention package that comprised of tuberculosis awareness and screening information was developed together with adolescents, thus; a human-centred approach was used. The package consisted of TB screening cards, poster messages and a local song. The song was broadcasted in the community radios. Poster messages were deployed in the community by the village health teams (VHTS). The TB screening cards were given to TB positive and presumptive adults to screen adolescents at home. Adolescents that were found with TB symptoms were referred to the project health facilities. Socio-demographic and clinical characteristics of eligible adolescents were collected in a period of six months from Kawolo, Iganga, Gombe and Kiwoko health facilities. To determine the effectiveness of the package, before and after intervention data were equally collected. A total of 394 adolescents were enrolled, majority (76%) were school going. The intervention improved adolescent TB care seeking in the four project health facilities. The average number of adolescents screened increased from 159 to 309 (incidence rate ratio (IRR) = 1.9, P<0.001, 95% CI [1.9, 2.0]). Those presumed to have TB increased from 13 to 29(IRR = 2.2, P<0.001, 95% CI [1.9, 2.5]). The ones tested with GeneXpert increased in average from 8 to 28(IRR = 3.3, P<0.001, 95% CI [2.8, 3.8]). There was a minimal increase in the average monthly number of adolescents with a positive result of 0.8, from 1.6 to 2.4(p = 0.170) and linkage to TB care services of 1.1, from 2 to 3.1(p = 0.154). The project improved uptake of TB services among adolescents along the TB care cascade. We recommend a robust and fully powered randomized controlled trial to evaluate the effectiveness of the Package.

Tuberculosis patients face high treatment support costs in Colombia, 2021.

OBJECTIVE: To estimate the baseline to measure one of the three indicators of the World Health Organization (WHO) End TB strategy (2015-2035), measure the costs incurred by patients affected by tuberculosis (TB) during a treatment episode and estimate the proportion of households facing catastrophic costs (CC) and associated risk factors, in Colombia, 2021. MATERIAL AND METHODS: A nationally representative cross-sectional survey was conducted among participants on TB treatment in Colombia, using telephone interviews due to the exceptional context of the COVID-19 pandemic. The survey collected household costs (direct [medical and non-medical out-of-pocket expenses] and indirect) over an episode of TB, loss of time, coping measures, self-reported income, and asset ownership. Total costs were expressed as a proportion of annual household income and analyzed for risk factors of CC (defined as costs above 20% annual household income). RESULTS: The proportion of TB-affected households incurring in costs above 20% annual household income (CC) was 51.7% (95%CI: 45.4-58.0) overall, 51.3% (95%CI: 44.9-57.7) among patients with drug-sensitive (DS) TB, and 65.0% (95%CI: 48.0-82.0) among drug-resistant (DR). The average patient cost of a TB case in Colombia was $1,218 (95%CI 1,106-1,330) including $860.9 (95%CI 776.1-945.7) for non-medical costs, $339 (95%CI 257-421) for the indirect costs, and $18.1 (95%CI 11.9-24.4) for the medical costs. The factors that influenced the probability of facing CC were income quintile, job loss, DR-TB patient, and TB type. CONCLUSION: Main cost drivers for CC were non-medical out-of-pocket expenses and income loss (indirect costs). Current social protection programs ought to be expanded to mitigate the proportion of TB-affected households facing CC in Colombia, especially those with lower income levels.

[The street as a space for care production: the singular therapeutic project and tuberculosis management in people experiencing homelessness during the Covid-19 pandemic in the city of Rio de Janeiro]. / La calle como espacio de producción de cuidados: el proyecto terapéutico singular y el manejo de la tuberculosis en personas en situación de calle durante la pandemia de covid-19 en la ciudad de Río de Janeiro.

From the theoretical perspective of the cartography of the micropolitics of living labor in action, the objective was to analyze the work process of the "street clinic" team based in a primary care unit in the city of Rio de Janeiro, Brazil, in the management of tuberculosis cases in the context of the Covid-19 pandemic. This is an exploratory qualitative research. Between May and December 2021, seven professionals from the street clinic team were interviewed, and participant observation was conducted with field diary records. Three thematic axes emerged from the interviews related to people experiencing homelessness in the context of the Covid -19 pandemic: 1) Challenges, potentialities, and weaknesses of tuberculosis care; 2) Building intersectoral care networks for monitoring individuals with tuberculosis; and 3) The street as a space for care production: the work process of the street clinic in tuberculosis management. It is concluded that caring for people experiencing homelessness with tuberculosis in the context of the Covid -19 pandemic requires not only managing clinical protocols but also building shared work with the intra and intersectoral network. In addition to the task of being in the territory, the outpatient service in the territory must also be a street outpatient service, especially regarding tuberculosis treatment.

Desde la perspectiva teórica de la cartografía de la micropolítica del trabajo vivo en acto, el objetivo fue analizar el proceso de trabajo del equipo del "consultorio en la calle" con sede en una unidad de atención básica de la ciudad de Río de Janeiro, Brasil, en el manejo de casos de tuberculosis, en el contexto de la pandemia de covid-19. Se trata de una investigación exploratoria con enfoque cualitativo. Entre mayo y diciembre de 2021, se entrevistaron a siete profesionales del equipo consultorio en la calle, y se realizó observación participante con registros en diario de campo. De las entrevistas surgieron tres ejes temáticos relacionados con la población en situación de calle en el contexto de la pandemia covid-19: 1) Desafíos, potencialidades y fragilidades del cuidado de la tuberculosis; 2) Construcción de redes de cuidados intersectoriales para el seguimiento de las personas con tuberculosis; y 3) La calle como espacio de producción de cuidado: el proceso de trabajo del consultorio en la calle en el manejo de la tuberculosis. Se concluye que la atención a personas en situación de calle con tuberculosis en el contexto de la pandemia covid-19 requiere no solo de la gestión de protocolos clínicos, sino también de la construcción de un trabajo compartido con la red intra e intersectorial. Además de la tarea de estar en el territorio, el servicio ambulatorio del territorio también debe ser un servicio ambulatorio de la calle, especialmente en lo que respecta al tratamiento de la tuberculosis.

Management of the infant born to a mother with tuberculosis: a systematic review and consensus practice guideline.

Infants born to mothers with tuberculosis disease are at increased risk of developing tuberculosis disease themselves. We reviewed published studies and guidelines on the management of these infants to inform the development of a consensus practice guideline. We searched MEDLINE, CINAHL, and Cochrane Library from database inception to Dec 1, 2022, for original studies reporting the management and outcome of infants born to mothers with tuberculosis. Of the 521 published papers identified, only three met inclusion criteria and no evidence-based conclusions could be drawn from these studies, given their narrow scope, variable aims, descriptive nature, inconsistent data collection, and high attrition rates. We also assessed a collection of national and international guidelines to inform a consensus practice guideline developed by an international panel of experts from different epidemiological contexts. The 16 guidelines reviewed had consistent features to inform the expert consultation process. Two management algorithms were developed-one for infants born to mothers considered potentially infectious at the time of delivery and another for mothers not considered infectious at the time of delivery-with different guidance for high and low tuberculosis incidence settings. This systematic review and consensus practice guideline should facilitate more consistent clinical management, support the collection of better data, and encourage the development of more studies to improve evidence-based care.

Exploring the Potential of Exosomes as Biomarkers in Tuberculosis and Other Diseases.

Tuberculosis (TB) is a major cause of morbidity and mortality and remains an important public health issue in developing countries worldwide. The existing methods and techniques available for the diagnosis of TB are based on combinations of laboratory (chemical and biological), radiological, and clinical tests. These methods are sophisticated and laborious and have limitations in terms of sensitivity, specificity, and accuracy. Clinical settings need improved diagnostic biomarkers to accurately detect biological changes due to pathogen invasion and pharmacological responses. Exosomes are membrane-bound vesicles and mediators of intercellular signaling processes that play a significant role in the pathogenesis of various diseases, such as tuberculosis, and can act as promising biomarkers for the monitoring of TB infection. Compared to conventional biomarkers, exosome-derived biomarkers are advantageous because they are easier to detect in different biofluids, are more sensitive and specific, and may be useful in tracking patients' reactions to therapy. This review provides insights into the types of biomarkers, methods of exosome isolation, and roles of the cargo (proteins) present in exosomes isolated from patients through omics studies, such as proteomics. These findings will aid in developing new prognostic and diagnostic biomarkers and could lead to the identification of new therapeutic targets in the clinical setting.

The Applications of ELISpot in the Identification and Treatment of Various Forms of Tuberculosis and in the Cancer Immunotherapies.

ELISpot (enzyme-linked immunospot) is a powerful immunological tool for the detection of cytokine-secreting cells at a single-cell resolution. It is widely used for the diagnosis of various infectious diseases, e.g., tuberculosis and sarcoidosis, and it is also widely used in cancer immunotherapy research. Its ability to distinguish between active and latent forms of tuberculosis makes it an extremely powerful tool for epidemiological studies and contact tracing. In addition to that, it is a very useful tool for the research and development of cancer immunotherapies. ELISpot can be employed to assess the immune responses against various tumor-associated antigens, which could provide valuable insights for the development of effective therapies against cancers. Furthermore, it plays a crucial role to the evaluation of immune responses against specific antigens that not only could aid in vaccine development but also assist in treatment monitoring and development of therapeutic and diagnostic strategies. This chapter briefly describes some of the applications of ELISpot in tuberculosis and cancer research.

Estimands for clinical endpoints in tuberculosis treatment randomized controlled trials: a retrospective application in a completed trial.

BACKGROUND: Randomized trials for the treatment of tuberculosis (TB) rely on a composite primary outcome to capture unfavorable treatment responses. However, variability between trials in the outcome definition and estimation methods complicates across-trial comparisons and hinders the advancement of treatment guidelines. The International Council for Harmonization (ICH) provides international regulatory standards for clinical trials. The estimand framework outlined in the recent ICH E9(R1) addendum offers a timely opportunity for randomized trials of TB treatment to adopt broadly standardized outcome definitions and analytic approaches. We previously proposed and defined four estimands for use in this context. Our objective was to evaluate how the use of these estimands and choice of estimation method impacts results and interpretation of a large phase III TB trial. METHODS: We reanalyzed participant-level data from the REMoxTB trial. We applied four estimands and various methods of estimation to assess non-inferiority of both novel 4-month treatment regimens against standard of care. RESULTS: With each of the four estimands, we reached the same conclusion as the original trial analysis that the novel regimens were not non-inferior to standard of care. Each estimand and method of estimation gave similar estimates of the treatment effect with fluctuations in variance and differences driven by the methods applied for handling intercurrent events. CONCLUSIONS: Our application of estimands defined by the ICH E9 (R1) addendum offers a formalized framework for addressing the primary TB treatment trial objective and can promote uniformity in future trials by limiting heterogeneity in trial outcome definitions. We demonstrated the utility of our proposal using data from the REMoxTB randomized trial. We outlined methods for estimating each estimand and found consistent conclusions across estimands. We recommend future late-phase TB treatment trials to implement some or all of our estimands to promote rigorous outcome definitions and reduce variability between trials. TRIAL REGISTRATION: ClinicalTrials.gov NCT00864383. Registered on March 2009.

Bacteriophage therapy for the treatment of Mycobacterium tuberculosis infections in humanized mice.

The continuing emergence of new strains of antibiotic-resistant bacteria has renewed interest in phage therapy; however, there has been limited progress in applying phage therapy to multi-drug resistant Mycobacterium tuberculosis (Mtb) infections. In this study, we show that bacteriophage strains D29 and DS6A can efficiently lyse Mtb H37Rv in 7H10 agar plates. However, only phage DS6A efficiently kills H37Rv in liquid culture and in Mtb-infected human primary macrophages. We further show in subsequent experiments that, after the humanized mice were infected with aerosolized H37Rv, then treated with DS6A intravenously, the DS6A treated mice showed increased body weight and improved pulmonary function relative to control mice. Furthermore, DS6A reduces Mtb load in mouse organs with greater efficacy in the spleen. These results demonstrate the feasibility of developing phage therapy as an effective therapeutic against Mtb infection.

The collaborative framework for the management of tuberculosis and type 2 diabetes syndemic in low- and middle-income countries: a rapid review.

INTRODUCTION: Given the absence of international guidelines on the joint management and control of tuberculosis (TB) and type 2 diabetes mellitus (T2D), the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (The Union) launched in 2011 a policy framework to address the growing syndemic burden of TB-T2D. This review aimed at mapping the available evidence on the implementation of the Union-WHO Framework, explicitly, or bi-directional TB-T2D health programs as an initiative for co-management in patients in low- and middle-income countries (LMIC). METHODS: A rapid review was performed based on a systematic search in PubMed and Web of Science electronic databases for peer-reviewed articles on The Union-WHO Framework and bi-directional interventions of TB and T2D in LMIC. The search was restricted to English language articles and from 01/08/2011 to 20/05/2022. RESULTS: A total of 24 articles from 16 LMIC met the inclusion criteria. Four described the implementation of The Union-WHO Framework and 20 on the bi-directional interventions of TB and T2D. Bi-directional activities were found valuable, feasible and effective following the Union-WHO recommendations. Limited knowledge and awareness on TB-T2D comorbidity was identified as one of the barriers to ensure a functional and effective integration of services. CONCLUSIONS: This review revealed that it is valuable, feasible and effective to implement bi-directional TB and T2D activities (screening and management) according to the Union-WHO Framework recommendations, especially in countries that face TB-T2D syndemic. Additionally, it was apparent that gaps still exist in research aimed at providing evidence of costs to implement collaborative activities. There is need for TB and T2D services integration that should be done through the well-stablished TB programme. This integration of two vertical programmes, could ensure patient-centeredness, continuum of care and ultimately contribute for health systems strengthening.

Community-level variation in TB testing history in Blantyre, Malawi.

SETTING: Equitable access to TB testing is vital for achieving global diagnosis and treatment targets, but access to diagnostic services is often worse in poorer communities. The SCALE (Sustainable Community-wide Active case-finding for Lung hEalth) survey estimated TB prevalence in Blantyre City, Malawi, and recorded previous engagement with TB services.OBJECTIVE: To explore local variation in the prevalence of ever-testing for TB in Blantyre and investigate potential socio-economic drivers.DESIGN: We fit a mixed-effects model to self-reported prior TB testing from survey participants across 72 neighbourhood clusters, adjusted for sex, age and HIV status and with cluster-level random intercepts. We then evaluated to what extent cluster-level variation was explained by two alternate poverty indicators.RESULTS: We observed substantial variation between clusters in previous TB testing, with little correlation between neighbouring clusters. Individuals residing in less affluent households, on average, had lower odds of having undergone prior testing. However, adjusting for poverty did not explain the cluster-level variations observed.CONCLUSION: Despite a decade of increased active case-finding efforts, access to TB testing is inconsistent across the population of Blantyre. This likely reflects health inequities that also apply to TB testing in many other settings, and motivates collection and analysis of TB testing data to identify the drivers behind these inequities.

[Rigid bronchoscopy combined with flexible bronchoscopy for treatment of central airway stenosis caused by tuberculous tracheobronchial fistula: report of 2 cases].

Tuberculous tracheobronchial fistulas are caused by mediastinal or hilar tuberculous lymph nodes ulcerating into the trachea or bronchus. Patients usually require flexible bronchoscopic interventional procedures in addition to systemic anti-tuberculosis chemotherapy in the ulceration phase. In this paper, we reported 2 cases of central airway stenosis caused by tuberculous tracheobronchial fistula, which had poor treatment results after flexible bronchoscopy. According to the patients' condition, the airway lesions were treated by rigid bronchoscopy combined with flexible bronchoscopy, cryotherapy, argon plasma coagulation, and so on. The central airway stenosis was resolved quickly, and the caseating lymph node tissue was removed as much as possible under the premise of ensuring safety, which shortened the recovery time of tuberculous fistula.

A cross-sectional analysis of the effectiveness of a nutritional support programme for people with tuberculosis in Southern Madagascar using secondary data from a non-governmental organisation.

BACKGROUND: There is a strong, bi-directional link between tuberculosis (TB) and undernutrition: TB often causes undernutrition, and undernourished people are more likely to contract TB and experience worse outcomes. Globally, several TB nutritional support programmes exist; however, evidence on their effectiveness is limited and contested. This study evaluates the effect of a nutritional support programme implemented for people with TB in the Atsimo-Andrefana region, Madagascar in 2022. Within this programme, undernourished people with TB [with a body mass index (BMI) of < 18.5 kg/m2] receive 0.6 L of vegetable oil and 6.0 kg of a soy-wheat blend per month throughout their TB treatment. METHODS: We analysed secondary non-governmental organisation data collected between January and November 2022 in the Atsimo-Andrefana region, Southern Madagascar, including information on an individual's medical conditions (e.g., type of TB, treatment outcomes) and nutritional status measured prior to, during, and after completion of treatment (e.g., height, weight, mid-upper arm circumference). We conducted descriptive analyses of patient baseline characteristics and outcomes to assess the impact of the provided nutritional support on the BMI of people with TB. RESULTS: A total of 1310 people with TB were included in the study [9.9% (130) children under the age of 5, 32.1% (420) children between 5 and 18 years, 58.0% (760) adults]. 55.4% of children under 5, 28.1% of children between ages 5 and 18, and 81.3% of adults were undernourished at treatment initiation. 42.3% (55/130) of children under 5 experienced severe acute malnutrition at treatment uptake. While the average BMI of adults with TB receiving food support increased over time, from 17.1 kg/m2 (interquartile range: 15.8-18.3, range: 10.3-22.5) to 17.9 kg/m2 (interquartile range: 16.6-19.1, range: 11.9-24.1), most adults remained undernourished even after completing TB treatment. CONCLUSIONS: The current TB nutritional support programme falls short of sufficiently increasing the BMI of people with TB to overcome malnutrition. There is an urgent need to revise the nutritional support available for people with TB, particularly for children under 5.

Pediatric Tuberculosis Infection Care Facilitators and Barriers: A Qualitative Study.

BACKGROUND: A total of 700 000 US children and adolescents are estimated to have latent tuberculosis (TB) infection. Identifying facilitators and barriers to engaging in TB infection care is critical to preventing pediatric TB disease. We explored families' and clinicians' perspectives on pediatric TB infection diagnosis and care. METHODS: We conducted individual interviews and small group discussions with primary care and subspecialty clinicians, and individual interviews with caregivers of children diagnosed with TB infection. We sought to elicit facilitators and barriers to TB infection care engagement. We used applied thematic analysis to elucidate themes relating to care engagement, and organized themes using a cascade-grounded pediatric TB infection care engagement framework. RESULTS: We enrolled 19 caregivers and 24 clinicians. Key themes pertaining to facilitators and barriers to care emerged that variably affected engagement at different steps of care. Clinic and health system themes included the application of risk identification strategies and communication of risk; care ecosystem accessibility; programs to reduce cost-related barriers; and medication adherence support. Patient- and family-level themes included TB knowledge and beliefs; trust in clinicians, tests, and medical institutions; behavioral skills; child development and parenting; and family resources. CONCLUSIONS: Risk identification, education techniques, trust, family resources, TB stigma, and care ecosystem accessibility enabled or impeded care cascade engagement. Our results delineate an integrated pediatric TB infection care engagement framework that can inform multilevel interventions to improve retention in the pediatric TB infection care cascade.

Antimicrobial Effect of Cannabidiol on Intracellular Mycobacterium tuberculosis.

Introduction: Mycobacterium tuberculosis, the etiologic agent of tuberculosis (TB), has killed nearly one billion people during the last two centuries. Nowadays, TB remains a major global health problem ranked among the top 10 causes of death worldwide. One of the main challenges in developing new strategies to fight TB is focused on reducing the duration and complexity of drug regimens. Cannabidiol (CBD) is the main nonpsychoactive ingredient extracted from the Cannabis sativa L. plant, which has been shown to be biologically active against bacteria. The purpose of this work was to investigate the antimicrobial effect of CBD on M. tuberculosis intracellular infection. Materials and Methods: To assess the minimum inhibitory concentration (MIC) of CBD on mycobacterial strains, the MTT assay was performed on Mycobacterium smegmatis, and the Colony-Forming Unit (CFU) assay was conducted on MtbH37Rv. Additionally, the cytotoxic effect of CBD on THP-1 cells was assessed by MTT assay. Moreover, macrophages derived from the THP-1 cell were infected with MtbH37Rv (multiplicity of infection 1:10) to evaluate the intracellular activity of CBD by determining the CFU/mL. Results: Antimicrobial activity against M. smegmatis (MIC=100 µM) and MtbH37Rv (MIC=25 µM) cultures was exhibited by CBD. Furthermore, the effect of CBD was also evaluated on MtbH37Rv infected macrophage cells. Interestingly, a reduction in viable intracellular MtbH37Rv bacteria was observed after 24 h of treatment. Moreover, CBD exhibited a safe profile toward human THP-1 cells, since it showed no toxicity (CC50=1075 µM) at a concentration of antibacterial effect (selectivity index 43). Conclusion: These results extend the knowledge regarding the antimicrobial activity of CBD and demonstrate its ability to kill the human intracellular pathogen M. tuberculosis.

Patient level barriers to accessing TB care services during the COVID-19 pandemic in Uganda, a mixed methods study.

INTRODUCTION: Lockdown measure has been utilized widely to mitigate COVID-19 pandemic transmission and recently during the 2022 Sudan Ebola Virus Disease outbreak in Uganda. These have setback effects on the continuity of essential health services such as tuberculosis (TB) care, reversing progress made in the fight against tuberculosis (TB) over the past decade. We set out to understand patient-reported barriers to accessing TB care services during the COVID-19 pandemic in Uganda. METHODS: Mixed methods study involving review of medical records of TB patients who received TB care from January to September 2020. We used quantitative and qualitative methods including phone questionnaires and in-depth interviews. We carried out descriptive statistics, a chi-square test and conducted a thematic analysis. RESULTS: We carried out phone interviews with 672 participants. The majority (60%) were male and with an average of 35 years (SD:11). A significantly higher proportion of patients reported a barrier to TB care access during the COVID-19 lockdown than pre-lockdown (79.9% vs. 68.1% p = 0.027). We carried out in-depth interviews with 28 participants (54% (15/28): male). Barriers experienced by these participants included lack of a means of transport to reach the health facility, lack of money to pay the transport fares, long distances to the facility, fear of COVID-19 infection, stigma due to overlap between TB and COVID-19 symptoms, and few health care workers available during the lockdown period. CONCLUSION: Lockdown measures instituted to mitigate the transmission of COVID1-19 affected access to TB care services in Uganda. Uganda is at risk of future emerging and re-emerging diseases of epidemic potential. Therefore, there should be measures to ensure the continuity of essential services such as tuberculosis care during the implementation of future epidemic response interventions such as a lockdown.

Individual journeys to tuberculosis care in Nigeria's private sector during the COVID-19 pandemic.

BACKGROUND: Pre-COVID-19, individuals with tuberculosis (TB) in Nigeria were often underdiagnosed and untreated. TB services were mostly in the public sector with only 15% of new cases in 2019 reported from the private sector. Reports highlighted challenges in accessing care in the private sector, which accounted for 67% of all initial care-seeking. Our study examined patients' health seeking pathways for TB in Nigeria's private sector and explored any changes to care pathways during COVID-19. METHODS: We conducted 180 cross-sectional surveys and 20 in-depth interviews with individuals having chest symptoms attending 18 high-volume private clinics and hospitals in Kano and Lagos States. Questions focused on sociodemographic characteristics, health-seeking behaviour, and pathways to care during the COVID-19 pandemic. All surveys and interviews were conducted in May 2021. RESULTS: Most participants were male (111/180), with an average age of 37. Half (96/180) sought healthcare within a week of symptoms, while few (20/180) waited over 2 months. Individuals testing positive for TB had more health-seeking delays, and those testing negative for TB had more provider delays. On average, participants visited two providers in Kano and 1.69 in Lagos, with 61 of 180 in Kano and 48 of 180 in Lagos visiting other providers before the recruitment facility. Private providers were the initial encounters for most participants (60/180 in Kano, 83/180 in Lagos). Most respondents (164/180) experienced short-lived pandemic-related restrictions, affecting access to transportation, and closed facilities. CONCLUSIONS: This study showed a few challenges in accessing TB care, necessitating continued investment in healthcare infrastructure and resources, particularly in the private sector. Understanding the different care pathways and delays in care provides opportunities for targeted interventions to improve deployment of services closer to where patients first seek care.
