Health worker perspectives on barriers to delivery of routine tuberculosis diagnostic evaluation services in Uganda: a qualitative study to guide clinic-based interventions

A qualitative study to inform the development of a decision support tool for the diagnosis of pulmonary tuberculosis in Tigray, Ethiopia

BACKGROUND

Tuberculosis (TB) is Ethiopia's leading infectious killer disease. The war in the Tigray region of Ethiopia has resulted in the disruption of TB care services. Prediction models are recommended to aid the diagnosis of TB in resource-limited settings. However, the development of such decision-support tools without the participation of end users may not be successful. To inform the tool development, we described barriers to diagnosing TB and identified applicable and desirable parameters for the proposed tool.

METHODS

We conducted a qualitative study between February and June 2023 in two cities in Tigray, Northern Ethiopia. We conducted 12 in-depth interviews and four focus group discussions with healthcare workers (HCWs). Interviews were translated, coded, and analyzed to identify predefined and emergent themes during the thematic analysis.

RESULTS

Healthcare workers used symptoms, risk factors, signs, and investigations to diagnose TB. However, failure to ask about antibiotic use, the absence and non-affordability of investigations, and patient load were barriers affecting the diagnosis of TB. Most of the classic TB symptoms and their duration were sorted as very important, simple, reliable, generalizable, and desirable indices. In addition, a trial of antibiotics, being chronically sick-looking, having HIV, having a contact history with a TB patient, and an erythrocyte sedimentation rate fulfilled the above criteria.

CONCLUSIONS

In the TB diagnostic process, HCWs account for a variety of data, but they prefer the classic symptoms of TB to heighten their clinical suspicion. Antibiotic trials and some risk factors were also considered reasonable. However, when HCWs have a heavy workload and a shortage of investigations, they experience a suboptimal TB diagnostic process. Hence, appropriate context consideration and care providers' preferences for parameters will inform tool development.

Individual, community and health systems factors influencing time to notification of tuberculosis: situating software and hardware bottlenecks in local health systems

BACKGROUND

Despite several global interventions, tuberculosis (TB) remains a leading cause of death affecting millions of people globally. Many TB patients either have no access to quality care or go undetected by national health systems. Several multilevel factors account for under-detection of persons with TB. This study sought to explore patient-related software, community and health systems software and hardware factors influencing time to notification of TB in Lusaka District, Zambia.

METHODS

This was an exploratory qualitative case study that adopted a software and hardware lens of conceptualizing health systems. Data were collected from across three sites - urban and peri-urban areas: Chongwe, Kafue, and Lusaka - within Lusaka Province, Zambia. Sixteen key informants - TB corner nurses, community TB treatment supporters, and TB program managers - were interviewed. Six focus groups were held with TB patients. Data were analyzed using thematic analysis.

RESULTS

The study identified factors influencing timely TB notification, categorized into software and hardware elements. Patient-related software elements, including TB knowledge and awareness, and health-seeking behavior, are crucial for prompt notification among TB patients. In the community health system, software elements like social stigma and undesirable community attitudes towards contact tracing, and hardware elements such as unbalanced schedules, excessive workload and limited capacity of community TB treatment supporters contribute to delayed TB notification. In the formal health system, software elements like negative attitudes of health providers towards TB patients and demotivation of TB staff, and hardware elements such as high diagnostics and transportation costs, outdated diagnostics in primary care facilities, and slow referral mechanisms, can also delay TB notification.

CONCLUSION

Delays in time to TB notification are influenced by a combination of software (attitudinal and behavioral) and hardware (resource-related) elements across TB patients, community health systems, community TB treatment supporters, health providers, and TB staff. Addressing these factors, particularly social stigma, negative attitudes, and resource constraints, is crucial to improving timely TB detection and treatment.

Health worker perspectives on barriers and facilitators of tuberculosis investigation coverage among index case contacts in rural Southwestern Uganda: a qualitative study

BACKGROUND

In 2012, the World Health Organization recommended screening and investigation of contacts of index tuberculosis patients as a strategy to accelerate detection of tuberculosis (TB) cases. Nine years after the adoption of this recommendation, coverage of TB contact investigations in Uganda remains low. The objective of this study was to examine health care providers' perceptions of factors influencing coverage of TB contact investigations in three selected rural health facilities in Mbarara district, southwestern Uganda.

METHODS

This study identified provider opinions on the barriers and facilitators to implementation of TB contact investigation using the Consolidated Framework for Implementation Research. Using an exploratory qualitative study design, semi-structured interviews with 19 health workers involved in the TB program at district, health facility and community levels were conducted from April 2020 and July 2020. Analysis was conducted inductively using reflexive thematic analysis in six iterative steps: familiarizing with the data, creating initial codes, searching for themes, reviewing themes, developing theme definitions, and writing the report.

RESULTS

Nineteen health care workers participated in this study which translates to a 100% response rate. These included two district TB and leprosy supervisors, five nurses, five clinical officers, six village health team members and one laboratory technician. The three themes that emerged from the analysis were intervention-related, health system and contextual factors. Health system-related barriers included inadequate or delayed government funding for the TB program, shortage of human resources, insufficient personal protective equipment, and a stock-out of supplies such as Xpert MTB cartridges. Contextual barriers included steep terrain, poverty or low income, and the stigma associated with TB and COVID-19. Facilitators comprised increased knowledge and understanding of the intervention, performance review and on-the-job training of health workers.

CONCLUSIONS

This study found that most of the factors affecting TB contact investigations in this rural community were related to health system constraints such as inadequate or delayed funding and human resource shortages. This can be addressed by strengthening the foundational elements of the health system - health financing and human resources - to establish a comprehensive TB control program that will enable the efficient identification of missing TB patients.

Evaluation of a short training course of chest X-ray interpretation for the diagnosis of paediatric TB

BACKGROUND

Chest X-ray (CXR) interpretation is challenging for the diagnosis of paediatric TB. We assessed the performance of a three half-day CXR training module for healthcare workers (HCWs) at low healthcare levels in six high TB incidence countries.

METHODS

Within the TB-Speed Decentralization Study, we developed a three half-day training course to identify normal CXR, CXR of good quality and identify six TB-suggestive features. We performed a pre-post training assessment on a pre-defined set of 20 CXR readings. We compared the proportion of correctly interpreted CXRs and the median reading score before and after the training using the McNemar test and a linear mixed model.

RESULTS

Of 191 HCWs, 43 (23%) were physicians, 103 (54%) nurses, 18 (9.4%) radiology technicians and 12 (6.3%) other professionals. Of 2,840 CXRs with both assessment, respectively 1,843 (64.9%) and 2,277 (80.2%) were correctly interpreted during pre-training and post-training (P < 0.001). The median reading score improved significantly from 13/20 to 16/20 after the training, after adjusting by country, facility and profession (adjusted β = 3.31, 95% CI 2.44-4.47).

CONCLUSION

Despite some limitations of the course assessment that did not include abnormal non-TB suggestive CXR, study findings suggest that a short CXR training course could improve HCWs' interpretation skills in diagnosing paediatric TB.

Predictors of mortality in Ugandan children with TB, 2016-2021

BACKGROUND: The burden of pediatric TB is high in Uganda. Our objective was to evaluate predictors of mortality during TB treatment among children at an urban and a rural referral hospital.METHODS: We designed a historical cohort study of TB cases at Mulago National Referral Hospital, Kampala; and Fort Portal Regional Referral Hospital, Fort Portal, Uganda, in children aged <15 years from 2016 to 2021. We used Kaplan-Meier models to estimate survival and fit multivariable Cox regression models to determine mortality hazards during TB treatment.RESULTS: We identified 1,658 children diagnosed with TB from 2016 to 2021. Of 1,623 children with known treatment outcomes, 127/1,623 (7.8%) died during TB treatment, 1,298/1,623 (78.3%) completed treatment, 150/1,623 (9.2%) were lost to follow-up, and two children failed treatment. Using Kaplan-Meier functions, the median time to death was 27 days following treatment initiation. In adjusted Cox models, predictors of mortality included HIV (aHR 1.68, 95% CI 1.01-2.81), moderate malnutrition (aHR 2.22, 95% CI 1.18-4.16), and severe malnutrition (aHR 2.92, 95% CI 1.75-4.87).CONCLUSION: Mortality was high at an urban and a rural referral hospital among children who initiated TB treatment from 2016 to 2021, with the majority of deaths occurring during the intensive phase of TB treatment. Malnutrition and HIV were significant predictors of death during treatment.

Factors associated with the unsuccessful TB treatment outcomes in the northern regions of Namibia: a mixed methods study

BACKGROUND

Tuberculosis (TB) is among the leading causes of death globally. The disease has a huge burden in Namibia, with a case notification rate of at least 442 per 100,000. To date, Namibia is among the countries with the highest global TB burden, despite all efforts to reduce it. This study aimed to determine the factors associated with the unsuccessful treatment outcomes of the Directly Observed Therapy Short course (DOTS) programme in the Kunene and Oshana regions.

METHODS

The study utilised a mixed-methods explanatory-sequential design to collect data from all TB patient records and healthcare workers who work directly with the DOTS strategy for TB patients. The relationship between independent and dependent variables was analysed using multiple logistic regression analysis, while interviews were analysed using inductive thematic analysis.

RESULTS

The overall treatment success rates of the Kunene and Oshana regions throughout the review period were 50.6% and 49.4%, respectively. The logistic regression analyses showed that in the Kunene region, the type of DOT used (Community-based DOTS) (aOR = 0.356, 95% CI: 0.835-2.768, p = 0.006) was statistically significant with the unsuccessful treatment outcomes. While in the Oshana region, age groups 21-30 years old (aOR = 1.643, 95% CI = 1.005-2.686, p = 0.048), 31-40 years old (aOR = 1.725, 95% CI = 11.026-2.9, p = 0.040), 41-50 years old (aOR = 2.003, 95% CI = 1.155-3.476, p = 0.013) and 51-60 years old (aOR = 2.106, 95% CI = 1.228-3.612, p = 0.007) had statistically significant associations with the poor TB-TO. Inductive thematic analysis revealed that patients in the Kunene region were challenging to reach owing to their nomadic lifestyle and the vastness of the area, adversely affecting their ability to observe TB therapy directly. In the Oshana region, it was found that stigma and poor TB awareness among adult patients, as well as mixing anti-TB medication with alcohol and tobacco products among adult patients, was a prevalent issue affecting TB therapy.

CONCLUSION

The study recommends that regional health directorates embark on rigorous community health education about TB treatment and risk factors and establish a robust patient observation and monitoring system to enhance inclusive access to all health services and ensure treatment adherence.

Clinician perspectives of drug-resistant tuberculosis care services in the Philippines

BACKGROUND/OBJECTIVES

In the Philippines, treatment success rates for drug-resistant tuberculosis (DR-TB) remains low and little is known about the quality of DR-TB services. This study aimed to explore clinician's perspectives of DR-TB care services.

METHODS

We conducted semi-structured in-depth interviews from January-March 2018 with 11 providers selected purposively to explore the barriers associated with DR-TB care service delivery, best practices, and recommendations for enhancing patient care. Emerging themes were organized according to the socio-ecological framework.

RESULTS

Five major themes were identified: (1) nurses do not feel empowered; (2) particular patients are left behind and more vulnerable than others; (3) infection control practices, fear, and limited capacity in rural health centers; (4) financial insecurity due to program reimbursement mechanisms; and (5) local government support is limited and requires more involvement in support of DR-TB elimination activities. Best practices focused on tailored approaches that eliminated structural, economic, and motivational barriers for patients. Participants recommended financial support from local government units, nutritional assistance for patients, and refresher training for healthcare workers.

CONCLUSION

The findings provide additional understanding regarding the barriers that limit successful DR-TB care delivery and provide critical information to improve clinical practice and develop public health interventions for frontline staff including nurses in the Philippines. These strategies could ultimately reduce disparities associated with access to care and treatment adherence, if implemented.

Factors affecting implementation of tuberculosis contact investigation and tuberculosis preventive therapy among children in Sabah, East Malaysia: A qualitative study

Contact investigation and TB preventive treatment of children under five years of age who are close contacts of a TB case is a key component of TB prevention. However, the uptake of TB preventive treatment is low in many high-TB burden settings. This study explores factors affecting the implementation of TB contact investigation and preventive treatment among children in Malaysia's city of Kota Kinabalu, Sabah State. This study was conducted in three primary health clinics between 2019 and 2020. We purposively sampled 34 parents and guardians of child contacts eligible for TB preventive treatment, and 25 healthcare providers involved in the management of child contacts. We conducted thematic analysis of semi-structured interviews and focus group discussions to illicit factors affecting implementation and uptake of TB contact investigation and TB preventive therapy. Six main themes emerged from the analyses-four of these relating to contact investigation and two relating to TB preventive therapy. Factors affecting TB contact investigation were addressed under system related factors (external factors, stakeholder collaboration, healthcare workers' and clients' concerns), clinic related factors (perceived performance, clinic schedule, and space), healthcare worker related factors (cooperation, commitment, knowledge, misconception, counselling and communication) and patient and contact related factors (cooperation and commitment). Factors affecting TB preventive treatment delivery were addressed under guardian related factors (cooperation, commitment, knowledge and misconception) and treatment related factors (child-friendly form and adverse effects). To address gaps and barriers identified in our study, we recommend developing system capacity to maintain routine contact investigation and preventive treatment in the context of external program risks, providing training to healthcare workers to address misconceptions, safeguarding vulnerable clients against the risk of detention and deportation while accessing care, ensuring public and private services are provided regardless of migration status, and improving processes and resources for contact investigation and preventive treatment.

Why health system diagnosis delay among tuberculosis patients in Illubabor, Oromia region, South West Ethiopia? A qualitative study

BACKGROUND

The main target of tuberculosis control and prevention is to detect incident cases as quickly as possible and also to prevent the occurrence of disease. It is also the responsibility of the health facility to screen the contacts, identifying children for prophylactic therapy. However, the target is difficult to meet due to issues within health facilities that cause health system diagnostic delays. Despite this, there is no information explored why health system diagnostic delays among tuberculosis patients.

METHOD

A qualitative study was conducted by using different data collection methods and sources. Seventeen DOT providers, five laboratory professionals, six program managers, and seven Tuberculosis patients were interviewed. In addition, 22 governmental health facilities were observed for the availability of resources. Data obtained from the in-depth interviews was transcribed, coded, categorized, and thematized manually.

RESULT

Health system Diagnosis delays reasons were related with sample collection procedures, poor competency of health professionals, in addition to absences or scarcity of health professionals, medical products, and basic infrastructure. We found 18 health facilities without skilled personnel in the OPD, 7 health facilities with a broken microscope, and almost all health facilities without a separate room for sputum examination. Furthermore, 12 (54.5%) and 14 (63.6%) health facilities lacked access to water and electric power, respectively.

CONCLUSION

Many reasons for TB diagnosis delays have been identified in the study area. Poor competence of health workers and scarcity of resources were identified. Depending on the finding, we suggest strengthening the health workers' training. Concrete strategies need to be designed to retain professionals. Training on human resource planning and budget preparation is needed for front-line managers. Managers have to work on the maintenance of diagnostic tools and facilitate transportation. The rural health facilities need to use another alternative power source.

Subacute Cardiac Tamponade Due to Tuberculous Pericarditis Diagnosed by Urine Lipoarabinomannan Assay in a Immunocompetent Patient in Oyam District, Uganda: A Case Report

BACKGROUND

Uganda ranks among the countries with the highest burden of TB the world and tuberculous pericarditis (TBP) affects up to 2% of people diagnosed with pulmonary tuberculosis worldwide. In Africa, it represents the most common cause of pericardial disease. Here, we present the case of a 21-year-old male patient who was diagnosed of cardiac tamponade due to tuberculous pericarditis with a positive urine LF-LAM.

CASE REPORT

We report a case of a 21-year-old male living in Oyam district, Uganda, who presented to the emergency department with difficulty in breathing, easy fatigability, general body weakness, and abdominal pain. A chest X-ray showed the presence of right pleural effusion and massive cardiomegaly. Thus, percutaneous pericardiocentesis was performed immediately and pericardial fluid resulted negative both for gram staining and real-time PCR test Xpert MTB/RIF. The following day's urine LF-LAM test resulted positive, and antitubercular therapy started with gradual improvement. During the follow-up visits, the patient remained asymptomatic, reporting good compliance to the antitubercular therapy.

CONCLUSION

Our case highlights the potential usefulness of a LF-LAM-based diagnostic approach, suggesting that, in low-resource settings, this test might be used as part of routine diagnostic workup in patients with pericardial disease or suspected extra-pulmonary tuberculosis.

Experience and Perception of Healthcare Workers on the Challenges of Follow-Up and Treatment of Tuberculosis Patients in Southern Ethiopia: An Exploratory-Descriptive Qualitative Study

Background

There is a scarcity of research evidence on TB follow-up and treatment challenges from a healthcare worker's perspective in Ethiopia. Therefore, this study aimed to explore and describe the experience and perception of healthcare workers on the challenges of follow-up and treatment of TB patients in Southern Ethiopia.

Material and Methods

A qualitative exploratory-descriptive study was employed among 26 purposely selected Healthcare Workers (HCWs) from Wolaita Sodo University-Comprehensive Specialized Hospital and Achura, Boloso Sore, and Tida Health Centers in December 2021 and January 2022. Initially, the maximum variation purposive sampling technique was employed, then based on the data requirement of the study it was enriched by a theoretical sampling method. The required data were collected through one-on-one face-to-face audio-taped in-depth interviews. Data analysis was conducted by using a qualitative data analysis framework for the applied research method. NVivo Software Version 11 was used to ease data organization and analysis. Detailed textual narration of subthemes, and themes was done using direct verbatim quotations in the respective headings and subheadings.

Results

In the current study, three major themes and eleven sub-themes emerged from the data. The three major themes include the experience of healthcare workers, perceived challenges, and suggestions for improvement of TB patients' follow-up and treatment. Healthcare worker's experience, compliance with infection prevention protocols, fear of contracting and/or spreading TB, public awareness of TB, socio-economic burdens, providers-related problems, shortage of medical supplies, unconducive physical work environment, provision of holistic support for the patients, provision of in or out of service training, and supportive supervision were the sub-themes.

Conclusion

This study explored the multidimensional challenges adjoining follow-up and treatment of TB patients. Regular monitoring and supportive supervision accompanied by appropriate and timely decisions and feedback are vital to ensure effective follow-up and treatment of TB patients in Ethiopia.

Determinants of losses in the tuberculosis infection cascade of care among children and adolescent contacts of pulmonary tuberculosis cases: A Brazilian multi-centre longitudinal study

Background

Approximately 10% of the global tuberculosis (TB) burden is in children. Identification, diagnosis, and early treatment of Mycobacterium tuberculosis infection (TBI) is critical to prevent progression to TB in children. The risk of TB, including severe disease, is highest in children <5 years old. We evaluated the cascade of TBI care among child and adolescent TB contacts to identify factors associated with losses in the cascade.

Methods

Close contacts ≤ 18 years old of pulmonary TB patients enrolled between 2015 and 2019 in a multi-centre Brazilian cohort were followed for up to 24 months and classified according to age groups: <5 years, 5-9 years, 10-14 years and 15-18 years. Data on clinical investigation, radiographic examination, IGRA testing at baseline and 6 months, initiation and completion of TB preventive treatment (TPT) were collected. Multivariable regression analyses identified factors associated with TBI and losses in the cascade of care in children and adolescents.

Findings

Among 1795 TB contacts initially identified, 530 (29·5%) were ≤18 years old. Losses for all steps in the cascade were especially high in children <5 years old (88%) because at this age all contacts are recommended to initiate TPT. As a proportion of all children, completion of TPT was low (between 10% and 13%) in all age-groups. Furthermore, multivariable regression revealed that younger age of contacts and TB index cases who were female, had pulmonary cavities, and persistent cough were independently associated with losses in the cascade of care among persons ≤18 years old.

Interpretation

Losses in the TBI cascade were the highest among children <5 years, which was the group at highest risk for TB among the four age groups. The findings highlight the need to improve screening, initiation, and completion of TPT of young children who are close contacts of people with TB in Brazil.

Patient and health system level barriers to and facilitators for tuberculosis treatment initiation in Uganda: a qualitative study

BACKGROUND

The WHO END TB strategy targets to place at least 90% of all patients diagnosed with Tuberculosis (TB) on appropriate treatment. In Uganda, approximately 20% of patients diagnosed with TB are not initiated on TB treatment. We sought to identify the patient and health system level barriers to and facilitators for TB treatment initiation in Uganda.

METHODS

We conducted the study at ten public health facilities (three primary care, four district and three tertiary referral hospitals). We carried out in-depth interviews with patients diagnosed with TB and key informant interviews with health managers. In addition, we held focus group discussions with healthcare workers involved in TB care. Data collection and thematic analysis of transcripts was informed by the Capability, Opportunity, Motivation and Behavior (COM-B) model. We identified relevant intervention functions using the Behavior Change Wheel.

RESULTS

We interviewed 79 respondents (31 patients, 10 health managers and 38 healthcare workers). Common barriers at the health facility level included; lack of knowledge about the proportion of patients not initiated on TB treatment (psychological capability); difficulty accessing sputum results from the laboratory as well as difficulty tracing patients due to inadequate recording of patient addresses (physical opportunity). At the patient level, notable barriers included long turnaround time for sputum results and lack of transport funds to return to health facilities (physical opportunity); limited TB knowledge (psychological capability) and stigma (social opportunity). The most important facilitators identified were quick access to sputum test results either on the date of first visit (same-day diagnosis) or on the date of first return and availability of TB treatment (physical opportunity). We identified education, restructuring of the service environment to improve sputum results turnaround time and enablement to improve communication of test results as relevant intervention functions to alleviate these barriers to and enhance facilitators for TB treatment initiation.

CONCLUSION

We found that barriers to treatment initiation existed at both the patient and health facility-level across all levels of the (Capability, Opportunity and Motivation) model. The intervention functions identified here should be tested for feasibility.

Rapid molecular tests for tuberculosis and tuberculosis drug resistance: a qualitative evidence synthesis of recipient and provider views

BACKGROUND

Programmes that introduce rapid molecular tests for tuberculosis and tuberculosis drug resistance aim to bring tests closer to the community, and thereby cut delay in diagnosis, ensure early treatment, and improve health outcomes, as well as overcome problems with poor laboratory infrastructure and inadequately trained personnel. Yet, diagnostic technologies only have an impact if they are put to use in a correct and timely manner. Views of the intended beneficiaries are important in uptake of diagnostics, and their effective use also depends on those implementing testing programmes, including providers, laboratory professionals, and staff in health ministries. Otherwise, there is a risk these technologies will not fit their intended use and setting, cannot be made to work and scale up, and are not used by, or not accessible to, those in need.

OBJECTIVES

To synthesize end-user and professional user perspectives and experiences with low-complexity nucleic acid amplification tests (NAATs) for detection of tuberculosis and tuberculosis drug resistance; and to identify implications for effective implementation and health equity.

SEARCH METHODS

We searched MEDLINE, Embase, CINAHL, PsycInfo and Science Citation Index Expanded databases for eligible studies from 1 January 2007 up to 20 October 2021. We limited all searches to 2007 onward because the development of Xpert MTB/RIF, the first rapid molecular test in this review, was completed in 2009.

SELECTION CRITERIA

We included studies that used qualitative methods for data collection and analysis, and were focused on perspectives and experiences of users and potential users of low-complexity NAATs to diagnose tuberculosis and drug-resistant tuberculosis. NAATs included Xpert MTB/RIF, Xpert MTB/RIF Ultra, Xpert MTB/XDR, and the Truenat assays. Users were people with presumptive or confirmed tuberculosis and drug-resistant tuberculosis (including multidrug-resistant (MDR-TB)) and their caregivers, healthcare providers, laboratory technicians and managers, and programme officers and staff; and were from any type of health facility and setting globally. MDR-TB is tuberculosis caused by resistance to at least rifampicin and isoniazid, the two most effective first-line drugs used to treat tuberculosis.

DATA COLLECTION AND ANALYSIS

We used a thematic analysis approach for data extraction and synthesis, and assessed confidence in the findings using GRADE CERQual approach. We developed a conceptual framework to illustrate how the findings relate.

MAIN RESULTS

We found 32 studies. All studies were conducted in low- and middle-income countries. Twenty-seven studies were conducted in high-tuberculosis burden countries and 21 studies in high-MDR-TB burden countries. Only one study was from an Eastern European country. While the studies covered a diverse use of low-complexity NAATs, in only a minority of studies was it used as the initial diagnostic test for all people with presumptive tuberculosis. We identified 18 review findings and grouped them into three overarching categories. Critical aspects users value People with tuberculosis valued reaching diagnostic closure with an accurate diagnosis, avoiding diagnostic delays, and keeping diagnostic-associated cost low. Similarly, healthcare providers valued aspects of accuracy and the resulting confidence in low-complexity NAAT results, rapid turnaround times, and keeping cost to people seeking a diagnosis low. In addition, providers valued diversity of sample types (for example, gastric aspirate specimens and stool in children) and drug resistance information. Laboratory professionals appreciated the improved ease of use, ergonomics, and biosafety of low-complexity NAATs compared to sputum microscopy, and increased staff satisfaction. Challenges reported to realizing those values People with tuberculosis and healthcare workers were reluctant to test for tuberculosis (including MDR-TB) due to fears, stigma, or cost concerns. Thus, low-complexity NAAT testing is not implemented with sufficient support or discretion to overcome barriers that are common to other approaches to testing for tuberculosis. Delays were reported at many steps of the diagnostic pathway owing to poor sample quality; difficulties with transporting specimens; lack of sufficient resources; maintenance of low-complexity NAATs; increased workload; inefficient work and patient flows; over-reliance on low-complexity NAAT results in lieu of clinical judgement; and lack of data-driven and inclusive implementation processes. These challenges were reported to lead to underutilization.  Concerns for access and equity The reported concerns included sustainable funding and maintenance and equitable use of resources to access low-complexity NAATs, as well as conflicts of interest between donors and people implementing the tests. Also, lengthy diagnostic delays, underutilization of low-complexity NAATs, lack of tuberculosis diagnostic facilities in the community, and too many eligibility restrictions hampered access to prompt and accurate testing and treatment. This was particularly the case for vulnerable groups, such as children, people with MDR-TB, or people with limited ability to pay. We had high confidence in most of our findings.

AUTHORS' CONCLUSIONS

Low-complexity diagnostics have been presented as a solution to overcome deficiencies in laboratory infrastructure and lack of skilled professionals. This review indicates this is misleading. The lack of infrastructure and human resources undermine the added value new diagnostics of low complexity have for recipients and providers. We had high confidence in the evidence contributing to these review findings. Implementation of new diagnostic technologies, like those considered in this review, will need to tackle the challenges identified in this review including weak infrastructure and systems, and insufficient data on ground level realities prior and during implementation, as well as problems of conflicts of interest in order to ensure equitable use of resources.

Barriers to tuberculosis case finding in primary and secondary health facilities in Ghana: perceptions, experiences and practices of healthcare workers

BACKGROUND

Ghana's national tuberculosis (TB) prevalence survey conducted in 2013 showed higher than expected TB prevalence indicating that many people with TB were not being identified and treated. Responding to this, we assessed barriers to TB case finding from the perspective, experiences and practices of healthcare workers (HCWs) in rural and urban health facilities in the Volta region, Ghana.

METHODS

We conducted structured clinic observations and in-depth interviews with 12 HCWs (including five trained in TB case detection) in four rural health facilities and a municipal hospital. Interview transcripts and clinic observation data were manually organised, triangulated and analysed into health system-related and HCW-related barriers.

RESULTS

The key health system barriers identified included lack of TB diagnostic laboratories in rural health facilities and no standard referral system to the municipal hospital for further assessment and TB testing. In addition, missed opportunities for early diagnosis of TB were driven by suboptimal screening practices of HCWs whose application of the national standard operating procedures (SOP) for TB case detection was inconsistent. Further, infection prevention and control measures in health facilities were not implemented as recommended by the SOP. HCW-related barriers were mainly lack of training on case detection guidelines, fear of infection (exacerbated by lack of appropriate personal protective equipment [PPE]) and lack of motivation among HCWs for TB work. Solutions to these barriers suggested by HCWs included provision of at least one diagnostic facility in each sub-municipality, provision of transport subsidies to enable patients' travel for testing, training of newly-recruited staff on case detection guidelines, and provision of appropriate PPE.

CONCLUSION

TB case finding was undermined by few diagnostic facilities; inconsistent referral mechanisms; poor implementation, training and quality control of a screening tool and guidelines; and HCWs fearing infection and not being motivated. We recommend training for and quality monitoring of TB diagnosis and treatment with a focus on patient-centred care, an effective sputum transport system, provision of the TB symptom screening tool and consistent referral pathways from peripheral health facilities.

Readiness to implement on-site molecular testing for tuberculosis in community health centers in Uganda

Background

Newer molecular testing platforms are now available for deployment at lower-level community health centers. There are limited data on facility- and health worker-level factors that would promote successful adoption of such platforms for rapid tuberculosis (TB) testing and treatment initiation. Our study aimed to assess readiness to implement onsite molecular testing at community health centers in Uganda, a high TB burden country in sub-Saharan Africa.

Methods

To understand implementation readiness, we conducted a qualitative assessment guided by the Consolidated Framework for Implementation Research (CFIR) at 6 community health centers in central and eastern Uganda between February and April 2018. We conducted 23 in-depth, semi-structured interviews with health workers involved in TB care at each health center to assess TB-related work practices and readiness to adopt onsite molecular testing using the GeneXpert Edge platform. Interviews were transcribed verbatim and coded for thematic analysis.

Results

Participants (N=23) included 6 nurses/nursing assistants, 6 clinicians, 6 laboratory directors/technicians, 1 medical officer, 2 health center directors, and 2 other health workers involved in TB care. Health workers described general enthusiasm that on-site molecular testing could lead to greater efficiencies in TB diagnosis and treatment, including faster turn- around time for TB test results, lack of need for trained laboratory technicians to interpret results, and reduced need to transport sputum specimens to higher level facilities. However, health workers also expressed concerns about implementation feasibility. These included uncertainty about TB infection risk, safety risks from disposal of hazardous waste, a lack of local capacity to provide timely troubleshooting and maintenance services, and concerns about the security of GeneXpert devices and accessories. Health workers also expressed the need for backup batteries to support testing or charging when wall power is unstable.

Conclusion

Our study generated a nuanced understanding of modifiable contextual barriers and led to direct revisions of implementation strategies for onsite molecular testing. The findings highlight that novel diagnostics should be implemented along with health system co-interventions that address contextual barriers to their effective uptake. Pre-implementation assessment of stakeholder perspectives, collaborative work processes, and institutional contexts is essential when introducing innovative technology in complex health care settings.

Multicomponent Strategy with Decentralized Molecular Testing for Tuberculosis

BACKGROUND

Effective strategies are needed to facilitate the prompt diagnosis and treatment of tuberculosis in countries with a high burden of the disease.

METHODS

We conducted a cluster-randomized trial in which Ugandan community health centers were assigned to a multicomponent diagnostic strategy (on-site molecular testing for tuberculosis, guided restructuring of clinic workflows, and monthly feedback of quality metrics) or routine care (on-site sputum-smear microscopy and referral-based molecular testing). The primary outcome was the number of adults treated for confirmed tuberculosis within 14 days after presenting to the health center for evaluation during the 16-month intervention period. Secondary outcomes included completion of tuberculosis testing, same-day diagnosis, and same-day treatment. Outcomes were also assessed on the basis of proportions.

RESULTS

A total of 20 health centers underwent randomization, with 10 assigned to each group. Of 10,644 eligible adults (median age, 40 years) whose data were evaluated, 60.1% were women and 43.8% had human immunodeficiency virus infection. The intervention strategy led to a greater number of patients being treated for confirmed tuberculosis within 14 days after presentation (342 patients across 10 intervention health centers vs. 220 across 10 control health centers; adjusted rate ratio, 1.56; 95% confidence interval [CI], 1.21 to 2.01). More patients at intervention centers than at control centers completed tuberculosis testing (adjusted rate ratio, 1.85; 95% CI, 1.21 to 2.82), received a same-day diagnosis (adjusted rate ratio, 1.89; 95% CI, 1.39 to 2.56), and received same-day treatment for confirmed tuberculosis (adjusted rate ratio, 2.38; 95% CI, 1.57 to 3.61). Among 706 patients with confirmed tuberculosis, a higher proportion in the intervention group than in the control group were treated on the same day (adjusted rate ratio, 2.29; 95% CI, 1.23 to 4.25) or within 14 days after presentation (adjusted rate ratio, 1.22; 95% CI, 1.06 to 1.40).

CONCLUSIONS

A multicomponent diagnostic strategy that included on-site molecular testing plus implementation supports to address barriers to delivery of high-quality tuberculosis evaluation services led to greater numbers of patients being tested, receiving a diagnosis, and being treated for confirmed tuberculosis.

Child Contact Case Management-A Major Policy-Practice Gap in High-Burden Countries

The 2021 Global Tuberculosis (TB) report shows slow progress towards closing the pediatric TB detection gap and improving the TB preventive treatment (TPT) coverage among child and adolescent contacts. This review presents the current knowledge around contact case management (CCM) in low-resource settings, with a focus on child contacts, which represents a key priority population for CCM and TPT. Compelling evidence demonstrates that CCM interventions are a key gateway for both TB case finding and identification of those in need of TPT, and their yield and effectiveness should provide a strong rationale for prioritization by national TB programs. A growing body of evidence is now showing that innovative models of care focused on community-based and patient-centered approaches to household contact investigation can help narrow down the CCM implementation gaps that we are currently facing. The availability of shorter and child-friendly TPT regimens for child contacts provide an additional important opportunity to improve TPT acceptability and adherence. Prioritization of TB CCM implementation and adequate resource mobilization by ministries of health, donors and implementing agencies is needed to timely close the gap.

Barriers and Motivators of private hospitals' engagement in Tuberculosis care in Uganda

INTRODUCTION

The involvement of private hospitals in Tuberculosis care in Uganda is still limited. There is a lack of literature about the barriers and motivators to private hospitals' engagement in Tuberculosis care in Uganda.

OBJECTIVE

To explore the barriers to and motivators of private hospitals' engagement in Tuberculosis care.

METHODS

The study employed a qualitative study design that utilized in-depth interviews with 13 private healthcare workers purposively selected in June 2020 due to their active involvement in Tuberculosis care from four urban private hospitals in Mbarara Municipality. An inductive, content analytic approach framed by the Consolidated Framework for Implementation Research, was used for analysis. The interviews were transcribed and coded to identify key themes using content analysis.

RESULTS

Focusing through the Consolidated Framework for Implementation Research, barriers to private hospitals' engagement were related to cost, external policies and incentives, structure characteristics, networks and communications, and knowledge and beliefs about the intervention. These include concerns regarding the payment of care by patients; indirect income-generating nature of Tuberculosis management; lack of drugs, registers, and diagnostic tools; lack of accreditation from the Ugandan Ministry of Health; limited space for keeping Tuberculosis patients; lack of proper follow-up mechanism; lack of training and qualified human resources; and delayed seeking of health care by the patients. Perceived high quality of care in the private hospitals; privacy and confidentiality concerns; proximity of private hospitals to patients; and formalization of partnerships between private hospitals and the government were the motivators that arose from the three constructs (relative advantage, patient needs, and resources, and engaging).

CONCLUSION

The engagement of private hospitals in Tuberculosis care requires commitment from key stakeholders supplemented with the organizational shared beliefs towards this change. There is a need for ensuring mechanisms for lessening these barriers to ensure full engagement of private hospitals in Tuberculosis care.

Gaps related to screening and diagnosis of tuberculosis in care cascade in selected health facilities in East Africa countries: A retrospective study

Introduction

East Africa countries (Tanzania, Kenya, and Uganda) are among tuberculosis high burdened countries globally. As we race to accelerate progress towards a world free of tuberculosis by 2035, gaps related to screening and diagnosis in the cascade care need to be addressed.

Methods

We conducted a three-year (2015–2017) retrospective study using routine program data in 21 health facilities from East Africa. Data abstraction were done at tuberculosis clinics, outpatient departments (OPD), human immunodeficiency virus (HIV) and diabetic clinics, and then complemented with structured interviews with healthcare providers to identify possible gaps related to integration, screening, and diagnosis of tuberculosis. Data were analyzed using STATA™ Version 14.1.

Results

We extracted information from 49,454 presumptive TB patients who were registered in the 21 facilities between January 2015 and December 2017. A total of 9,565 tuberculosis cases were notified; 46.5% (4,450) were bacteriologically confirmed and 31.5% (3,013) were HIV-infected. Prevalence of tuberculosis among presumptive pulmonary tuberculosis cases was 17.4%. The outcomes observed were as follows: 79.8% (7,646) cured or completed treatment, 6.6% (634) died, 13.3% (1,270) lost to follow-up or undocumented and 0.4% (34) treatment failure. In all countries, tuberculosis screening was largely integrated at OPD and HIV clinics. High patient load, weak laboratory specimen referral system, shortage of trained personnel, and frequent interruption of laboratory supplies were the major cited challenges in screening and diagnosis of tuberculosis.

Conclusion

Screening and diagnostic activities were frequently affected by scarcity of human and financial resources. Tuberculosis screening was mainly integrated at OPD and HIV clinics, with less emphasis on the other health facility clinics. Closing gaps related to TB case finding and diagnosis in developing countries requires sustainable investment for both human and financial resources and strengthen the integration of TB activities within the health system.

Challenges in delivery of tuberculosis Services in Ethiopian Pastoralist Settings: clues for reforming service models and organizational structures

Background

The End-TB strategy aims to see a world free of tuberculosis (TB) by the coming decade through detecting and treating all cases irrespective of socioeconomic inequalities. However, case detections and treatment outcomes have not been as they should be in Somali pastoral settings of Ethiopia. Hence, this study aimed to explore the challenges that hinder the delivery and utilization of TB services in pastoral areas.

Methods

A qualitative study was conducted between December 2017 and October 2018 among pastoralist patients with delay of ≥2 months in seeking healthcare, healthcare providers and programme managers. Data were collected from different sources using 41 in-depth interviews, observations of facilities and a review meeting of providers from 50 health facilities. The data were transcribed, coded and analyzed to identify pre-defined and emerging sub-themes. ATLAS.ti version 7.0 was used for coding data, categorizing codes, and visualizing networks.

Results

Poor knowledge of TB and its services, limited accessibility (unreachability, unavailability and unacceptability), pastoralism, and initial healthcare-seeking at informal drug vendors that provide improper medications were the key barriers hindering the uptake of TB medical services. Inadequate infrastructure, shortage of trained and enthused providers, interruptions of drugs and laboratory supplies, scarce equipment, programme management gaps, lack of tailored approach, low private engagement, and cross-border movement were the major challenges affecting the provision of TB services for pastoral communities. The root factors were limited potential healthcare coverage, lack of zonal and district TB units, mobility and drought, strategy and funding gaps, and poor development infrastructure.

Conclusion

In pastoral settings of Ethiopia, the major challenges of TB services are limited access, illicit medication practices, inadequate resources, structural deficits, and lack of tailored approaches. Hence, for the pastoral TB control to be successful, mobile screening and treatment modalities and engaging rural drug vendors will be instrumental in enhancing case findings and treatment compliance; whereas, service expansion and management decentralization will be essential to create responsive structures for overcoming challenges.

Missed opportunities in tuberculosis investigation and associated factors at public health facilities in Uganda

Background

The incidence of tuberculosis (TB) is high in Uganda; yet, TB case detection is low. The population-based survey on the prevalence of TB in Uganda revealed that only 16% of presumptive TB patients seeking care at health facilities were offered sputum microscopy or chest-X ray (CXR). This study aimed to determine the magnitude of, and patient factors associated with missed opportunities in TB investigation at public health facilities of Wakiso District in Uganda.

Methods

A facility-based cross-sectional survey was conducted at 10 high volume public health facilities offering comprehensive TB services in Wakiso, Uganda, among adults (≥18 years) with at least one symptom suggestive of TB predefined according to the World Health Organisation criteria. Using exit interviews, data on demographics, TB symptoms, and clinical data relevant to TB diagnosis were collected. A missed opportunity in TB investigation was defined as a patient with symptoms suggestive of TB who did not have sputum and/or CXR evaluation to rule out TB. Poisson regression analysis was performed to determine factors associated with missed opportunities in TB investigation.

Results

Two hundred forty-seven (247) patients with presumptive TB exiting at antiretroviral therapy (ART) clinics (n = 132) or general outpatient clinics (n = 115) at public health facilities were recruited into this study. Majority of participants were female (161/247, 65.2%) with a mean + SD age of 35.1 + 11.5 years. Overall, 138 (55.9%) patients with symptoms suggestive of TB disease did not have sputum and/or CXR examinations. Patients who did not inform health workers about their TB related symptoms were more likely to miss a TB investigation (adjusted prevalence ratio (aPR): 1.68, 95%CI; 1.36–2.08, P < 0.001). However, patients who reported duration of cough of 2 weeks or more were less likely to be missed for TB screening (aPR; 0.69, 95%CI; 0.56–0.86, p < 0.001).

Conclusion

There are substantial missed opportunities for TB diagnosis in Wakiso District. While it is important that patients should be empowered to report symptoms, health workers need to proactively implement the WHO TB symptom screen tool and complete the subsequent steps in the TB diagnostic cascade.

Measuring fidelity to delivery of a new smoking cessation intervention integrated into routine tuberculosis care in Pakistan and Bangladesh: Contextual differences and opportunities

INTRODUCTION

Tobacco smoking among tuberculosis (TB) patients leads to poorer treatment outcomes. Smoking cessation support should be integrated into routine TB care. We measured healthcare providers' fidelity to a smoking cessation intervention integrated into routine TB care, in Bangladesh and Pakistan. We aimed to understand the role of providers and settings in the implementation of behavior support (BS) messages for TB and smoking cessation.

METHODS

The integrated BS intervention was implemented in TB clinics (24 public and 1 private). Cross-sectional data were collected on the fidelity of delivery of the BS intervention using a predefined fidelity index based on an existing validated method of measuring intervention fidelity. Audio-recordings of patient-provider BS sessions were coded using the fidelity index. Intervention fidelity was presented as the proportion of sessions that implemented BS messages.

RESULTS

A total of 96 sessions were conducted, 37 in Bangladesh and 59 in Pakistan. In public settings, TB medication advice was offered in 91.9% (95% CI: 78.7- 97.2) of sessions in Bangladesh, and in 75.5% (95% CI: 62.4-85.1) of sessions in Pakistan; whilst it was offered in 83.3% (95% CI: 43.7-97.0) of sessions in the private setting in Pakistan. Patients' smoking status was assessed in 70.3% (95% CI: 54.2-82.5) of sessions in Bangladesh, and in 34.0% (95% CI: 22.7-47.4) of sessions in the public setting and in 66.7% (95% CI: 30.0-90.3) of sessions in the private setting in Pakistan. A quit date was set in 32.4% (95% CI: 19.6-48.5) of all sessions in Bangladesh, and in 33.3% (95% CI: 9.6-70.0) of all sessions in the public setting in Pakistan.

CONCLUSIONS

Fidelity to the intended delivery of the intervention was found to be high for TB-related messages but not for smoking cessation messages. Clinic contexts may play a mediating role in health workers' opportunities to deliver the intervention as planned.

Patient Perspectives and Willingness to Accept Incentives for Tuberculosis Diagnostic Evaluation in Uganda

OBJECTIVES

We assessed attitudes and perceptions and willingness to accept (WTA) varying incentive structures for completing tuberculosis (TB) diagnostic evaluation among patients in Uganda.

METHODS

We surveyed 177 adult patients undergoing TB evaluation at 10 health centers between September 2018 and March 2019. We collected household sociodemographic information and assessed attitudes and perceptions of incentives. We surveyed patients regarding their willingness to complete TB diagnostic evaluation in exchange for incentives ranging in value from 500 Ugandan shillings (USh) to 25 000USh (~$0.15-$6.75). We compared associations between WTA and patient characteristics using ordered logistic regression.

RESULTS

Participant willingness to return to the health center to complete TB diagnostic evaluation increased proportionally with incentive amount. The median participant accepted between 2000 and 5000 USh. Cash (52%) and transportation vouchers (34%) were the most popular incentive types. Half of respondents preferred unconditional incentives; for a multiday evaluation, 84% preferred conditioning incentive receipt upon returning to the health center. In multivariate models, we found the pairwise difference between the third and lowest income quartile (aOR = 2.38, 95% CI: 1.20-4.69; P = .01), younger age, and difficulty returning to the health center to be significantly associated with WTA higher incentive thresholds.

CONCLUSIONS

In Uganda, incentives such as cash transfers or transportation vouchers are an acceptable intervention for facilitating adherence to TB diagnostic evaluation. Household income is associated with preferred incentive structure and amount, especially for those at the cusp of the poverty threshold who are more likely to prefer unconditional and higher valued incentives. Targeted and context-specific socioeconomic supports for at-risk patients are needed to optimize outcomes.

Barriers to accessing TB clinics among Myanmar TB patients attending a Thailand‐Myanmar border hospital: a qualitative approach

Purpose

This qualitative approach study aimed to understand the barriers to accessing a tuberculosis (TB) clinic in a Thai hospital as experienced by TB patients from Myanmar living on the Thailand-Myanmar border.

Design/methodology/approach

Twenty-two participants were asked to provide information. In-depth interviews were used to gather the information. Each interview lasted 40 min.

Findings

TB patients from Myanmar experience several barriers to accessing TB treatment and care at Mae Sai Hospital, such as language and economic problems, although they are very satisfied with the quality of service and positive attitude of the health care providers. A long waiting time and lack of explanation of the pathogenesis of TB were noted as negative aspects by the patients and their relatives. The medical staff at the TB clinic were negatively affected by the excessive workload and unsuitability of some methods or technologies. Using budgetary subsidies from agencies to fund TB care and treatment was not sustainable. Foreign TB patients are not subsidized by the national universal insurance scheme of Thailand, and sending TB patients back to their home country is sometimes unavoidable.

Originality/value

Thailand and Myanmar should strengthen their collaboration and develop a system to improve the quality of TB patient care and management for those who are living in poverty and lack education, by focusing on reducing language and economic barriers to accessing health care services including support for medicines and laboratory materials related to TB case management among these populations.

Design and execution of a public randomization ceremony to enhance stakeholder engagement within a cluster randomized trial to improve tuberculosis diagnosis in Uganda

Public randomization ceremonies have been proposed as a strategy to strengthen stakeholder engagement and address concerns and misconceptions associated with trial randomization. However, there are few published examples that describe how to conduct a public randomization ceremony with meaningful stakeholder engagement or how such ceremonies impact stakeholder perceptions about randomization and the randomization process. Cluster randomization for the GeneXpert Performance Evaluation for Linkage to Tuberculosis Care (XPEL-TB) trial was conducted at a public randomization ceremony attended by 70 stakeholders in Kampala, Uganda. Presentations given by the Acting Assistant Commissioner from the Uganda National Tuberculosis and Leprosy Programme and trial investigators emphasized how the trial aimed to further national TB goals, as well as how stakeholders contributed to the intervention design. The purpose and process of randomization were described using simple text and visuals. Randomization was an interactive activity that required participation of stakeholders from each trial site. A survey administered to stakeholders at the end of the ceremony suggested high comprehension of randomization (98%), trust in the randomization process (96%), and satisfaction with randomization outcomes (96%). Public randomization ceremonies should be considered more routinely to engage stakeholders in and address potential concerns about the fairness and impartiality of the randomization process for community-based trials.

Treatment outcomes of drug susceptible Tuberculosis in private health facilities in Lagos, South-West Nigeria

Background

The Lagos State Tuberculosis, Buruli Ulcer, and Leprosy Control Program (LSTBLCP) started engaging private hospitals under the Public-Private Mix (PPM) Program in 2008. The study aimed to evaluate the trend and predictors of successful Tuberculosis (TB) treatment outcomes of patients managed across these private health facilities between 2010–2016 in Lagos, Nigeria.

Methods

Retrospective review of TB treatment register and treatment cards of patients commenced on TB treatment between January 2010 and December 2016 in 36 private health facilities engaged by the LSTBLCP. Between December 2016 and February 2017, data were collected and entered into Microsoft Excel by trained data entry clerks. The analysis was done using SPSS software. Independent predictors of successful treatment outcomes were determined using multivariate analysis at the statistical significance of p<0.05 and 95% confidence interval.

Results

A total of 1660 records of TB patients were reviewed. 1535 (92.47%) commenced treatment, while 1337 (87.10%) of all records had documented treatment outcomes. Of the 1337 patients with outcomes, 1044 (78.09%) had a successful treatment outcome, and 293 (21.91%) had an unsuccessful outcome. Majority were male, 980 (59.04%), Human Immunodeficiency Virus (HIV) negative status, 1295 (80.24%), diagnosed with smear, 1141 (73.14%), treated in private not-for-profit (PNFP) hospital, 1097 (66.08%), treated for TB between 2014–2016 (18.96%-19.52%). In multivariate analysis, age>20years (aOR = 0.26, p = 0.001), receiving TB treatment in 2013 (aOR = 0.39, p = 0.001), having genexpert for TB diagnosis (aOR = 0.26, p = 0.031) and being HIV positive (aOR = 0.37, p = 0.001) significantly reduced likelihood of successful treatment outcome. The site of TB, being on ART or CPT, were confounding determinants of successful treatment outcomes as they became non-significant at the multivariate analysis level.

Conclusion

Treatment outcome among Lagos private hospitals was low compared with NTBLCP and World Health Organization (WHO) target. We urge the government and TB stakeholders to strengthen the PPM interventions to improve adherence, particularly among People Living with HIV (PLHIV) and older TB patients. Hence, promotion of early care-seeking, improving diagnostic and case holding efficiencies of health facilities, and TB/HIV collaborative interventions can reduce the risk of an unsuccessful outcome.

Anti-Tuberculosis Commodities Management Performance and Factors Affecting It at Public Health Facilities in Dire Dawa City Administration, Ethiopia

Background

Health facilities (HFs) need extensive ranges of anti-tuberculosis (TB) drugs and related TB laboratory commodities (LCs) for diagnosis, prevention, and treatment of TB and multi-drug-resistance (MDR)-TB. This study was aimed to assess anti-TB commodities management performance at public HFs of Dire Dawa city administration, Ethiopia.

Methods

A cross-sectional study design in 16 HFs providing TB and MDR-TB related service using quantitative and qualitative method was conducted. Semi-structured questionnaires and observation checklists with logistic indicators assessment tools were used to collect data. We used an in-depth interview and analyzed using a thematic approach. Quantitative data were entered into Epi-Data version 3.1 and transported to SPSS version 20 to analyze the results. Chi-square was used to test the association and a P-value<0.05 was statistically significant.

Results

The majority(13; 81.3%) of HFs used a health commodity management information system. Forty-two (40%) bin cards (BCs) for first line anti-TB drugs were not updated, while 62.5% of BCs were updated for second line drugs. On average, 43% of HFs accurately reported a report and requisition format (RRF) had significant association with the presence of a logistic management information system (LMIS) and standard operating procedure (P=0.019). Of the HFs, 50% had good storage conditions and guidelines (P=0.041). Regimen change (56.3%; P=0.035), receive near expiry (56.3%; P=0.035), and defective practice to first expired-first-out (50%; P=0.007) were reasons for wastages. About 50% and 66.6% of HFs were stocked out for isoniazid 300 mg, rifampicin, isoniazid, pyrazinamide (RHZ fixed dose), and ethambutol 400 mg with a mean stock out duration of 10.8, 18.9, and 70.5 days, respectively. Regimen change (68.8%; P=0.026), low demand (56.3%; P=0.041), and delay to resupply (37.5%; P=0.041) were reasons for stock out of anti-TB commodities.

Conclusion

Anti-TB drugs and LCs management performance of the HFs were found to be defective, which was confirmed by unsatisfactory data records, inconstant reports, deprived stock record accuracy, long lead time, high stock out rate, wastages, defective storage conditions, lack of training, and management support. Hence, respective organizations should improve their responsible activities to secure an uninterrupted supply of anti-TB drugs and LCs.

A Qualitative Insight into Barriers to Tuberculosis Case Detection in East Gojjam Zone, Ethiopia

Tuberculosis (TB) remains to be the leading cause of morbidity and mortality in the developing world. Early TB case detection (TCD) and treatment of infectious cases is vital to reduce the TB burden. The objective of this study was to identify possible barriers to TCD in East Gojjam Zone, northwest Ethiopia. The study used a descriptive phenomenological research method. The study participants included 21 TB patients, six TB control officers, and 40 health workers (HWs) selected by a heterogeneous purposive sampling technique. In-depth interviews and focus group discussions were used to collect data. Interviews were audio recorded, transcribed verbatim, translated, and thematically analyzed using NVivo 12 software (developed by QSR International Qualitative Software Developer, Melbourne, Australia). The study participants identified numerous barriers to TCD which were grouped into three major themes and 14 subthemes: 1) patient-related barriers including rural residence, low income, poor health literacy, and health-seeking delay; 2) healthcare system barriers grouped into two subthemes: HWs barriers (shortage of HWs, lack of training access, and low level of knowledge and skills) and health facility barriers (health service delay, using only passive TCD strategy, poor health education provision, and lack of regular supervision and timely feedback); 3) sociocultural and environmental barriers which included stigma and discrimination, lack of health information sources, poor transportation infrastructure, and community resistance. In conclusion, the TCD activity which is one of the pillars of the TB control program has been confronted with several patient-related, environmental, and healthcare system-related barriers. Improving community health literacy, scale-up access, and improving quality of TB diagnostic services, conducting regular supportive supervision and provision of timely feedback, arranging regular refresher training and staff motivation and recruitment schemes, and engaging local health officials and political leaders to address budgetary problems for TB and transportation infrastructure challenges are imperative interventions to enhance the TCD efforts in the study area.

Magnitude and Reasons for Gaps in Tuberculosis Diagnostic Testing and Treatment Initiation: An Operational Research Study from Dakshina Kannada, South India

Background: In India, ensuring all Persons with Presumptive TB (PPTB) undergo TB diagnostic tests and initiating all diagnosed TB patients on treatment are two major implementation challenges.

Objectives: In a coastal district of Karnataka state, South India, to (1) determine the number and proportion of PPTB who did not undergo any TB diagnostic test, and the number and proportion of TB patients who were not initiated on treatment (2) explore the facilitators and barriers in TB diagnostic testing and treatment initiation from health care providers’ perspective.

Methods: For objective-1, we used a cross-sectional design involving review of data of PPTB enrolled for care during January–March 2019 and for objective-2, we used a qualitative design involving key informant interviews of health care providers.

Results: Of 8822 PPTB patients enrolled for evaluation of TB, 767 (9%) had not undergone any TB diagnostic test. In those who had undergone any TB diagnostic test, a total of 822 were diagnosed with TB and of them, 26 (3%) were not initiated on treatment. Cartridge-based nucleic acid amplification tests was used as a diagnostic test only among 1188 (13.5%) PPTB patients. The gaps in diagnostic testing were due to: non-availability of doctors/lab-technicians, inadequate knowledge about TB diagnostic tests among health care providers, reluctance of patients to undergo the TB diagnostic tests due to stigma/confidentiality issues and sub-optimal engagement of private health facilities for TB control.

Conclusion: About 9% of PPTB not undergoing any test for TB and 3% of the TB patients not initiated on treatment are of major concern. Revised National TB Control Programme needs to address the identified barriers to improve the process of TB diagnosis and treatment initiation.

Pre-diagnostic drop out of presumptive TB patients and its associated factors at Bugembe Health Centre IV in Jinja, Uganda

BACKGROUND

Drop out of presumptive TB individuals before making a final diagnosis poses a danger to the individual and their community. We aimed to determine the proportion of these presumptive TB drop outs and their associated factors in Bugembe Health Centre, Jinja, Uganda.

METHODS

We used data from the DHIS2, presumptive and laboratory registers of Bugembe Health Centre IV for 2017. Descriptive statistics were used to summarize the population characteristics. A modified Poisson regression model via the generalized linear model (GLM) with log link and robust standard errors was used for bivariate and multivariate analysis.We used data from the DHIS2, presumptive and laboratory registers of Bugembe Health Centre IV for 2017. Descriptive statistics were used to summarize the population characteristics. A modified Poisson regression model via the generalized linear model (GLM) with log link and robust standard errors was used for bivariate and multivariate analysis.

RESULT

Among the 216 registered presumptive TB patients who were less than 1% of patients visiting the outpatients' department, 40.7% dropped out before final diagnosis was made. Age and HIV status were significantly associated with pre-diagnostic drop out while gender and distance from the health center were not.

CONCLUSION

A high risk to individuals and the community is posed by the significant proportion of presumptive TB patients dropping out before final diagnosis. Health systems managers need to consider interventions targeting young persons, male patients, HIV positive persons.

Study protocol: a cluster randomized trial to evaluate the effectiveness and implementation of onsite GeneXpert testing at community health centers in Uganda (XPEL-TB)

BACKGROUND

Delays in diagnosis and treatment of tuberculosis (TB) remain common in high-burden countries. To improve case detection, substantial investments have been made to scale-up Xpert MTB/RIF (Xpert), a cartridge-based nucleic acid amplification test that can detect TB within 2 hours, as a replacement for sputum smear microscopy. However, the optimal strategy for implementation of Xpert testing remains unclear.

METHODS

The Xpert Performance Evaluation for Linkage to Tuberculosis Care (XPEL-TB) trial uses an ultra-pragmatic, hybrid type II effectiveness-implementation design to assess the effectiveness and implementation of a streamlined strategy for delivery of Xpert testing in real-world settings. Twenty health centers with TB microscopy units were selected to participate in the trial, with ten health centers randomized to the intervention strategy (onsite molecular testing using GeneXpert Edge, process redesign to facilitate same-day TB diagnosis and treatment, and performance feedback) or routine care (onsite sputum smear microscopy plus referral of sputum samples to Xpert testing sites). The primary outcome is the number of patients with microbiologically confirmed TB who were initiated on treatment within 14 days of presentation to the health center, which reflects successful completion of the TB diagnostic evaluation process. Secondary outcomes include health outcomes (6-month vital status), as well as measures of the reach, adoption, and implementation of the intervention strategy.

DISCUSSION

The design elements and implementation approach for the XPEL-TB trial were intentionally selected to minimize disruptions to routine care procedures, with the goal of limiting their influence on key primary and secondary outcomes. Trial findings may result in increased support and funding for rapid, onsite molecular testing as the standard-of-care for all patients being evaluated for TB.

Challenges of Tuberculosis Control in Lagos State, Nigeria: A Qualitative Study of Health-Care Providers' Perspectives

Background:

Tuberculosis (TB) burden in Nigeria is a reflection of the challenges of TB control strategy in the country. This study explored the challenges encountered by the health workers in public and private TB treatment centers in Lagos, Nigeria.

Methods:

In-depth interviews were held with 34 health workers providing TB services in private and public health facilities and the Lagos state Program Officer between October 1, 2016 and January 31, 2017. The transcripts were read severally and coded for qualitative data analysis. Themes were developed from coding.

Results:

Insufficient or lack of funds to track patients lost to follow-up, conduct home visits, collect drugs from the central stores, and shortage of laboratory reagents were some of the logistical challenges encountered by the health workers. There was shortage of health workers and some were yet to be trained resulting in work overload. This was situation aggravated by the frequent redeployment and health worker attrition in the public and private sector respectively.

Conclusion:

The government need be proactive and show leadership by finding lasting solutions to the logistical and human resource challenges facing the LAgos State TB and Leprosy Program.

Implementation science to improve the quality of tuberculosis diagnostic services in Uganda

Nucleic acid amplification tests such as Xpert MTB/RIF (Xpert) have the potential to revolutionize tuberculosis (TB) diagnostics and improve case finding in resource-poor settings. However, since its introduction over a decade ago in Uganda, there remain significant gaps along the cascade of care for patients undergoing TB diagnostic evaluation at peripheral health centers. We utilized a systematic, implementation science-based approach to identify key reasons at multiple levels for attrition along the TB diagnostic evaluation cascade of care. Provider- and health system-level barriers fit into four key thematic areas: human resources, material resources, service implementation, and service coordination. Patient-level barriers included the considerable costs and time required to complete health center visits. We developed a theory-informed strategy using the PRECEDE framework to target key barriers by streamlining TB diagnostic evaluation and facilitating continuous quality improvement. The resulting SIMPLE TB strategy involve four key components: 1) Single-sample LED fluorescence microscopy; 2) Daily sputum transport to Xpert testing sites; 3) Text message communication of Xpert results to health centers and patients; and 4) Performance feedback to health centers using a quality improvement framework. This combination of interventions was feasible to implement and significantly improved the provision of high-quality care for patients undergoing TB diagnostic evaluation. We conclude that achieving high coverage of Xpert testing services is not enough. Xpert scale-up should be accompanied by health system co-interventions to facilitate effective implementation and ensure that high quality care is delivered to patients.

Quality of Same-Day Sputum Smears Microscopy and Presumptive Tuberculosis Patients Drop-out at Health Facilities of Addis Ababa, Ethiopia

BACKGROUND

Same-day sputum microcopy is recommended in areas where sputum smear microscopy external quality assessment (EQA) is effectively implemented and sturdy. In Addis Ababa, the status of EQA and drop-out of same-day sputum smear microcopy has not yet been assessed. The objective of this study was to assess the quality of same-day sputum smear microscopy and diagnostic drop-out of presumptive tuberculosis (TB) patients in health facilities (HFs) across Addis Ababa, Ethiopia.

METHODS

Amulti-analysis was conducted from September 2016 to July 2017 to determine the status of external quality assessment and diagnostic drop-out of presumptive TB patients registered for same-day sputum smear microscopy. Data was coded and entered in Microsoft Excel, and subsequently transferred and analyzed using SPSS version 20.0.

RESULTS

The drop-out of same-day sputum smear microscopy was 209 (6.2%). More than 33% of the specimens collected for purposes of same-day sputum smears were of poor quality. Among the selected HFs for the study: 13 (46.4%) used filter reagents prior to sputum smear staining while 75% of the selected HFs for the study used smear microscopy services interruption in a year. The sensitivity and specificity of the HFs participating in regional quality assessment scheme for the diagnosis of TB was 97.4% and 99.6%, respectively.

CONCLUSION

The diagnostic drop-out of same-day sputum smear microscopy was high in Addis Ababa. Strengthening EQA, competency-based laboratory professionals training on sputum smear microscopy might reduce the reading errors in sputum smear. Awareness creation of the community on the benefits gained from completion of specimen provision for the same-day approach decreases diagnostic drop-out and enhances TB control program.

Urban-rural disparities in treatment outcomes among recurrent TB cases in Southern Province, Zambia

BACKGROUND

At least 13-20% of all Tuberculosis (TB) cases are recurrent TB. Recurrent TB has critical public health importance because recurrent TB patients have high risk of Multi-Drug Resistant TB (MDR-TB). It is critical to understand variations in the prevalence and treatment outcomes of recurrent TB between different geographical settings. The objective of our study was to estimate the prevalence of recurrent TB among TB cases and compare risk of unfavorable treatment outcomes between rural and urban settings.

METHODS

In a retrospective cohort study conducted in southern province of Zambia, we used mixed effects logistic regression to asses associations between explanatory and outcome variables. Primary outcome was all-cause mortality and exposure was setting (rural/urban). Data was abstracted from the facility TB registers.

RESULTS

Overall 3566 recurrent TB cases were diagnosed among 25,533 TB patients. The prevalence of recurrent TB was 15.3% (95% CI: 14.8 15.9) in urban and 11.3% (95% CI: 10.7 12.0) in rural areas. Death occurred in 197 (5.5%), 103 (2.9%) were lost to follow-up, and 113 (3.2%) failed treatment. Rural settings had 70% higher risk of death (adjusted OR: 1.7; 95% CI: 1.2 2.7). Risk of lost to follow-up was twice higher in rural than urban (adjusted OR: 2.0 95% CI: 1.3 3.0). Compared to HIV-uninfected, HIV-infected individuals on Antiretroviral Treatment (ART) were 70% more likely to die (adjusted OR: 1.7; 95% CI: 1.2 3.1).

CONCLUSION

Recurrent TB prevalence was generally high in both urban and rural settings. The risk of mortality and lost to follow-up was higher among rural patients. We recommend a well-organized Directly Observed Therapy strategy adapted to setting where heightened TB control activities are focused on areas with poor treatment outcomes.

Improvisation and harm avoidance: An ethnographic study of adherence to postnatal care protocols in two hospitals in Southern Ghana

Providers' adherence to case management protocols can affect quality of care. However, how and why protocols are adhered to by frontline health workers in low- and middle-income countries is not always clear. This study explored midwives' adherence to national postnatal care protocols in two public hospitals in Southern Ghana using an ethnographic study design. Ninety participant observations and 88 conversations were conducted over a 20-months period, and two group interviews held with the midwives in the two hospitals. Data was analysed using a grounded theory approach. Findings: Midwives collectively decided when to adhere, modify or totally ignore postnatal care protocols. Adherence often occurred if required resources (equipment, tools, supplies) were available. Modification occurred when midwives felt that strict adherence could have negative implications for patients and they could be seen as acting 'unprofessionally'. Ignoring or modifying protocols also occurred when midwives were uncertain of the patient's health condition; basic supplies, logistics and infrastructure needed for adherence were unavailable or inappropriate; or midwives felt they might expose themselves or their clients to physical, psychological, emotional, financial or social harm. Regardless of the reasons that midwives felt justified to ignore or modify postnatal care protocols, it appeared in many instances to lead to the provision of care of suboptimal quality. Conclusion and recommendations: Providing clinical decision-making protocols is not enough to improve mother and new born care quality and outcomes. Faced with constraining conditions of work, providers are likely to modify guidelines as part of coping behaviour. Addressing constraining conditions of work must accompany guidelines. This includes adequate risks protection for health workers and clients; and resolution of deficits in essential equipment, infrastructure, supplies and staffing.

Explaining the successes and failures of tuberculosis treatment programs; a tale of two regions in rural eastern Uganda

Background

Optimally performing tuberculosis (TB) programs are characterized by treatment success rate (TSR) of at least 90%. In rural eastern Uganda, and elsewhere in sub Saharan Africa, TSR varies considerably across district TB programs and the reasons for the differences are unclear. This study explored factors associated with the low and high TSR across four districts in rural eastern Uganda.

Methods

We interviewed District TB and Leprosy Supervisors, Laboratory focal persons, and health facility TB focal persons from four districts in eastern Uganda as key informants. Interviews were audio recorded, transcribed verbatim, and imported into ATLAs.ti where thematic content analysis was performed and results were summarized into themes.

Results

The emerging themes were categorized as either facilitators of or barriers to treatment success. The emerging facilitators prevailing in the districts with high rates of treatment success were using data to make decisions and design interventions, continuous quality improvement, capacity building, and prioritization of better management of people with TB. The barriers common in districts with low rates of treatment success included lack of motivated and dedicated TB focal persons, scarce or no funding for implementing TB activities, and a poor implementation of community-based directly observed therapy short course.

Conclusion

This study shows that several factors are associated with the differing rates of treatment success in rural eastern Uganda. These factors should be the focus for TB control programs in Uganda and similar settings in order to improve rates of treatment success.

Challenges with accessing health care for young children presumed to have malaria in the rural district of Butaleja, Uganda: a qualitative study

Objective:

A qualitative study was conducted to gain insight into challenges reported by Butaleja households during a previous household survey. Specifically, this paper discusses heads of households’ and caregivers’ perceptions of challenges they face when seeking care for their very young children with fever presumed to be malaria.

Methods:

Eleven focus groups (FGs) were carried out with household members (five with heads of households and six with household caregivers) residing in five sub-counties located across the district. Purposive sampling was used to ensure the sample represented the religious diversity and geographical distance from the peri-urban center of the district. Each FG consisted of five to six participants. The FGs were conducted at a community centre by two pairs of researchers residing in the district and who were fluent in both English and the local dialect of Lunyole. The discussions were recorded, translated, and transcribed. Transcripts were reviewed and coded with the assistance of QDA Miner (version 4.0) qualitative data management software, and analyzed using thematic content analysis.

Results:

The FG discussions identified four major areas of challenges when managing acute febrile illness in their child under the age of five with presumed malaria (1) difficulties with getting to public health facilities due to long geographical distances and lack of affordable transportation; (2) poor service once at a public health facility, including denial of care, delay in treatment, and negative experiences with the staff; (3) difficulties with managing the child’s illness at home, including challenges with keeping home-stock medicines and administering medicines as prescribed; and (4) constrained to use private outlets despite their shortcomings.

Conclusions:

Future interventions may need to look beyond the public health system to improve case management of childhood malaria at the community level in rural districts such as Butaleja. Given the difficulties with accessing quality private health outlets, there is a need to partner with the private sector to explore feasible models of community-based health insurance programs and expand the role of informal private providers.

Improving the design of studies evaluating the impact of diagnostic tests for tuberculosis on health outcomes: a qualitative study of perspectives of diverse stakeholders

Background: Studies evaluating the impact of Xpert MTB/RIF testing for tuberculosis (TB) have demonstrated varied effects on health outcomes with many studies showing inconclusive results. We explored perceptions among diverse stakeholders about studies evaluating the impact of TB diagnostic tests, and identified suggestions for improving these studies. Methods: We used purposive sampling with consideration for differing expertise and geographical balance and conducted in depth semi-structured interviews. We interviewed English-speaking participants, including TB patients, and others involved in research, care or decision-making about TB diagnostics. We used the thematic approach to code and analyse the interview transcripts. Results: We interviewed 31 participants. Our study showed that stakeholders had different expectations with regard to test impact and how it is measured. TB test impact studies were perceived to be important for supporting implementation of tests but there were concerns about the unrealistic expectations placed on tests to improve outcomes in health systems with many influencing factors. To improve TB test impact studies, respondents suggested conducting health system assessments prior to the study; developing clear guidance on the study methodology and interpretation; improving study design by describing questions and interventions that consider the influences of the health-care ecosystem on the diagnostic test; selecting the target population at the health-care level most likely to benefit from the test; setting realistic targets for effect sizes in the sample size calculations; and interpreting study results carefully and avoiding categorisation and interpretation of results based on statistical significance alone. Researchers should involve multiple stakeholders in the design of studies. Advocating for more funding to support robust studies is essential. Conclusion: TB test impact studies were perceived to be important to support implementation of tests but there were concerns about their complexity. Process evaluations of their health system context and guidance for their design and interpretation are recommended.

Quality of care in childhood tuberculosis diagnosis at primary care clinics in Kampala, Uganda

OBJECTIVE

To assess the quality of routine childhood tuberculosis (TB) evaluation in Kampala, Uganda.

SETTING AND DESIGN

This was a cross-sectional study of children aged <15 years attending six government-run clinics from November 2015 to December 2016. Clinicians completed a standardized patient record form for all child visits. We assessed the following performance indicators of TB evaluation developed based on the Desk Guide of the International Union Against Tuberculosis and Lung Disease, an evidence-based decision aid on childhood TB diagnosis and management for clinicians: proportion screened for TB symptoms or contact history, proportion referred for laboratory evaluation if screen-positive, and proportion treated for TB if test-positive or meeting clinical criteria.

RESULTS

Of 24 566 consecutive children enrolled, 11 614 (47%) were fully screened for TB symptoms. Of 1747 (15%) children who screened positive, 360 (21%) had sputum examined, including 159 (44%) using smear microscopy, 244 (67%) using Xpert® MTB/RIF, and 52 (14%) using both techniques. Treatment was initiated in 18/20 (80%) children who tested positive. An additional 65 screen-positive children met the clinical criteria for TB; none were initiated on treatment.

CONCLUSIONS

Large gaps exist along the pathway to diagnosis and treatment of childhood TB. There is an urgent need for enhanced implementation of evidence-based approaches to TB diagnosis to improve outcomes in childhood TB.

Patterns of usage and preferences of users for tuberculosis-related text messages and voice calls in Uganda

BACKGROUND

Little information exists about mobile phone usage or preferences for tuberculosis (TB) related health communications in Uganda.

METHODS

We surveyed household contacts of TB patients in urban Kampala, Uganda, and clinic patients in rural central Uganda. Questions addressed mobile phone access, usage, and preferences for TB-related communications. We collected qualitative data about messaging preferences.

RESULTS

We enrolled 145 contacts and 203 clinic attendees. Most contacts (58%) and clinic attendees (75%) owned a mobile phone, while 42% of contacts and 10% of clinic attendees shared one; 94% of contacts and clinic attendees knew how to receive a short messaging service (SMS) message, but only 59% of contacts aged 45 years (vs. 96% of contacts aged <45 years, P = 0.0001) did so. All contacts and 99% of clinic attendees were willing and capable of receiving personal-health communications by SMS. Among contacts, 55% preferred detailed messages disclosing test results, while 45% preferred simple messages requesting a clinic visit to disclose results.

CONCLUSIONS

Most urban household TB contacts and rural clinic attendees reported having access to a mobile phone and willingness to receive TB-related personal-health communications by voice call or SMS. However, frequent phone sharing and variable messaging abilities and preferences suggest a need to tailor the design and monitoring of mHealth interventions to target recipients.

Governance of tuberculosis control programme in Nigeria

Background

The role of governance in strengthening tuberculosis (TB) control has received little research attention. This review provides evidence of how institutional designs and organisational practices influence implementation of the national TB control programme (NTP) in Nigeria.

Main text

We conducted a scoping review using a five-stage framework to review published and grey literature in English, on implementation of Nigeria’s NTP and identified themes related to governance using a health system governance framework. We included articles, of all study designs and methods, which described or analysed the processes of implementing TB control based on relevance to the research question.

The review shows a dearth of studies which examined the role of governance in TB control in Nigeria. Although costed plans and policy coordination framework exist, public spending on TB control is low. While stakeholders’ involvement in TB control is increasing, institutional capacity is limited, especially in the private sector. TB-specific legislation is absent. Deployment and transfer of staff to the NTP are not transparent. Health workers are not transparent in communicating service entitlements to users. Despite existence of supportive policies, integration of TB control into the community and general health services have been weak. Willingness to pay for TB services is high, however, transaction cost and stigma among patients limit equity. Effectiveness and efficiency of the NTP was hindered by inadequate human resources, dilapidated service delivery infrastructure and weak drug supply system. Despite adhering to standardized recording and reporting format, regular monitoring and evaluation, revision of reporting formats, and electronic data management system, TB surveillance system was found to be weak. Delay in TB diagnosis and initiation of care, poor staff attitude to patients, lack of privacy, poor management of drug reactions and absence of infection control measures breach ethical standards for TB care.

Conclusions

This scoping review of governance of TB control in Nigeria highlights two main issues. Governance for strengthening TB control programmes in low-resource, high TB burden settings like Nigeria, is imperative. Secondly, there is a need for empirical studies involving detailed analysis of different dimensions of governance of TB control.

Quality of care for patients evaluated for tuberculosis in the context of Xpert MTB/RIF scale-up

RATIONALE

Many high-burden countries are scaling-up Xpert MTB/RIF using a hub-and-spoke model. We evaluated the quality of care for patients undergoing TB evaluation at microscopy centers (spokes) linked to Xpert testing sites (hubs) in Uganda.

OBJECTIVES

To characterize the extent to which patients were receiving care in accordance with international and national guidelines.

METHODS

We conducted a prospective cohort study of all adults with presumptive pulmonary TB at 24 health centers linked to Xpert testing sites. Health center staff photographed TB registers, and uploaded photos to a secure server bi-weekly. We assessed the proportion of patients (1) initiating testing; (2) completing testing; and (3) treated for confirmed TB within 14 days.

MEASUREMENTS AND MAIN RESULTS

Between January to December 2017, 6744 patients underwent evaluation for pulmonary TB. Only 1316 patients had sputum referred for Xpert testing, including 1075/3229 (33.3%) people living with HIV and 241/3515 (6.9%) without HIV. Of 119 patients confirmed to have TB by Xpert testing, 44 (36%) did not initiate treatment. There were significant losses along the entire diagnostic cascade of care, with only 5330/6744 (79.0%) patients having samples referred for sputum-based testing, 2978/5330 (55.9%) patients completing recommended testing if referred, and 313/418 (74.9%) patients initiating treatment within 14 days if confirmed to have TB.

CONCLUSIONS

Although coverage of Xpert testing services across Uganda is high, the quality of care delivered to patients undergoing TB evaluation remains poor. Further research is needed to identify health system interventions to facilitate uptake of Xpert testing and high-quality care.

Health Workers' Perspectives on the Outcomes, Enablers, and Barriers to the Implementation of HIV "Test and Treat" Guidelines in Abuja, Nigeria

We evaluated health workers' perspectives on the implementation of the 2016 HIV "Test and Treat" guidelines in Nigeria. Using semi-structured interviews, qualitative data was collected from twenty health workers meeting inclusion criteria in six study sites. Data exploration was conducted using thematic content analysis. Participants perceived that the "Test and Treat" guidelines improved care for PLHIV, though they also perceived possible congested clinics. Perceived key factors enabling guidelines use were perceived patient benefits, availability of policy document and trainings. Perceived key barriers to guidelines use were poverty among patients, inadequate human resources and stock-outs of HIV testing kits. Further improvements in uptake of guidelines could be achieved by effecting an efficient supply chain system for HIV testing kits, and improved guidelines distribution and capacity building prior to implementation. Additionally, implementing differentiated approaches that decongest clinics, and programs that economically empower patients, could improve guidelines use, as Nigeria scales "Test and Treat" nationwide.

Feasibility of a streamlined tuberculosis diagnosis and treatment initiation strategy

OBJECTIVE:

To assess the feasibility of a streamlined strategy for improving tuberculosis (TB) diagnostic evaluation and treatment initiation among patients with presumed TB.

DESIGN:

Single-arm interventional pilot study at five primary care health centers of a streamlined, SIngle-saMPLE (SIMPLE) TB diagnostic evaluation strategy: 1) examination of two smear results from a single spot sputum specimen using light-emitting diode fluorescence microscopy, and 2) daily transportation of smear-negative sputum samples to Xpert® MTB/RIF testing sites.

RESULTS:

Of 1212 adults who underwent sputum testing for TB, 99.6% had two smears examined from the spot sputum specimen. Sputum was transported for Xpert testing within 1 clinic day for 83% (907/1091) of the smear-negative patients. Of 157 (13%) patients with bacteriologically positive TB, 116 (74%) were identified using sputum smear microscopy and 41 (26%) using Xpert testing of smear-negative samples. Anti-tuberculosis treatment was initiated in 142 (90%) patients with bacteriologically positive TB, with a median time to treatment of 1 day for smear-positive patients and 6 days for smear-negative, Xpert-positive patients.

CONCLUSION:

The SIMPLE TB strategy led to successful incorporation of Xpert testing and rapid treatment initiation in the majority of patients with bacteriologically confirmed TB in a resource-limited setting.

Empiric tuberculosis treatment in South African primary health care facilities - for whom, where, when and why: Implications for the development of tuberculosis diagnostic tests

Background

The extent and circumstances under which empiric tuberculosis (TB) treatment (treatment without microbiological confirmation at treatment initiation) is administered in primary health care settings in South Africa are not well described.

Methods

We used data from a pragmatic evaluation of Xpert MTB/RIF in which persons undergoing TB investigations by PHC nurses were followed for six months. Following Xpert or smear-microscopy at enrolment, investigations for tuberculosis were undertaken at the discretion of health care workers. We identified persons whose TB treatment was initiated empirically (no microbiological confirmation at time of treatment initiation at a primary health care facility) and describe pathways to treatment initiation.

Results

Of 4665 evaluable participants, 541 persons were initiated on treatment of whom 167 (31%) had negative sputum tests at enrolment. Amongst these 167, the median number of participant visits to health care providers prior to treatment initiation was 3 (interquartile range [IQR] 2–4). Chest radiography, sputum culture or hospital referral was done in 106/167 (63%). Reasons for TB treatment start were: 1) empiric (n = 82, 49%); 2) a positive laboratory test (n = 49, 29%); 3) referral and treatment start at a higher level of care (n = 28, 17%); and 4) indeterminable (n = 8, 5%). Empiric treatment accounted for 15% (82/541) of all TB treatment initiations and 1.7% (82/4665) of all persons undergoing TB investigations. Chest radiography findings compatible with TB (63/82 [77%]) were the basis for treatment initiation amongst the majority of empirically treated participants. Microbiological confirmation of TB was subsequently obtained for 11/82 (13%) empirically-treated participants. Median time to empiric treatment start was 3.9 weeks (IQR 1.4–11 weeks) after enrolment.

Conclusion

Uncommon prescription of empiric TB treatment with reliance on chest radiography in a nurse-managed programme underscores the need for highly sensitive TB diagnostics suitable for point-of-care, and strong health systems to support TB diagnosis in this setting.

Tuberculosis treatment success among rural and urban Ugandans living with HIV: a retrospective study

Setting: Government health centres and hospitals (six urban and 20 rural) providing tuberculosis (TB) treatment for people living with the human immunodeficiency virus (PLHIV) in central and western Uganda. Objective: To identify and quantify modifiable factors that limit TB treatment success among PLHIV in rural Uganda. Design: A retrospective cross-sectional review of routine Uganda National Tuberculosis and Leprosy Programme clinic registers and patient files of HIV-positive patients who received anti-tuberculosis treatment in 2014. Results: Of 191 rural patients, 66.7% achieved treatment success compared to 81.1% of 213 urban patients. Adjusted analysis revealed higher average treatment success in urban patients than in rural patients (OR 3.95, 95%CI 2.70-5.78, P < 0.01, generalised estimating equation model). Loss to follow-up was higher and follow-up sputum smear results were less frequently recorded in TB clinic registers among rural patients. Patients receiving treatment at higher-level facilities in rural settings had greater odds of treatment success, while patients receiving treatment at facilities where drug stock-outs had occurred had lower odds of treatment success. Conclusion: Lower reported treatment success in rural settings is mainly attributed to clinic-centred factors such as treatment monitoring procedures. We recommend strengthening treatment monitoring and delivery.

Protocol for a qualitative synthesis of barriers and facilitators in implementing guidelines for diagnosis of tuberculosis

INTRODUCTION

Despite the introduction of new tests and guidelines for diagnosis of tuberculosis (TB), worldwide case detection rate of TB is still suboptimal. This could be in part explained by the poor implementation of TB diagnostic guidelines. We aim to identify, appraise and synthesise qualitative evidence exploring the barriers and facilitators to implementing TB diagnostic guidelines.

METHODS AND ANALYSIS

A systematic review of qualitative studies will be conducted. Relevant electronic databases will be searched and studies included based on predefined inclusion criteria. We will also search reference lists, grey literature, conduct forward citation searches and contact relevant content experts. An adaptation of the Critical Appraisal Skills Programme tool will be used to assess the methodological quality of included studies. Two authors will review the search output, extract data and assess methodological quality independently, resolving any disagreements by consensus. We will use the thematic framework analysis approach based on the Supporting the Use of Research Evidence thematic framework to analyse and synthesise our data. We will apply the Confidence in the Evidence from Reviews of Qualitative research approach to transparently assess our confidence in the findings of the systematic review.
