Governance of tuberculosis control programme in Nigeria

System-wide governance challenges of the Ebonyi State Malaria Elimination Programme and recommendations for malaria health system strengthening: a qualitative study among stakeholders in Ebonyi state, Nigeria

OBJECTIVES

The burden of malaria has persistently been high in Ebonyi state and Nigeria despite long-standing collaborations with international partners with huge and increased amounts of financial investments. We explored the system-wide governance challenges of the Ebonyi State Malaria Elimination Programme (SMEP) and the factors responsible in order to make recommendations for malaria health system strengthening.

DESIGN

We did a qualitative study informed by the health system governance framework by Mikkelsen-Lopez et al and Savedoff's concept of governance.

SETTING AND PARTICIPANTS

Between 18 October 2022 and 8 November 2022, 25 semistructured face-to-face in-depth interviews were conducted in English with purposively selected key stakeholders in the Ebonyi SMEP aged 18 years or older with at least 2 years of involvement in the SMEP and who gave consent.

ANALYSIS

Data were analysed deductively and the analytical strategy was informed by the framework method for the analysis of qualitative data by Gale et al. RESULTS: Many system-wide governance challenges of the SMEP were identified including the absence of state's strategic vision and plans for malaria elimination; very weak primary and secondary healthcare systems; inadequate financial allocation and untimely release of budgeted funds by the state government; lack of human resources for health and very poor mosquito net distribution system. Other challenges were inadequate stakeholders' participation; poor accountability culture; impaired transparency and corruption and impaired ability to address corruption. The fundamental responsible factors were the lack of state government's concern for people's welfare and lack of interest and commitment to the malaria elimination effort, chronic non-employment of staff and lack of human resources in the entire health sector including SMEP, and nepotism and godfatherism.

CONCLUSIONS

The system-wide governance challenges and the responsible factors call for changing the 'business as usual' and refocusing on strengthening malaria health system governance in addressing the persisting malaria health problems in Ebonyi state (and Nigeria).

Telemedicine as a tool to prevent multi-drug resistant tuberculosis in poor resource settings: Lessons from Nigeria

Background

This mini review aims to provide an overview of the role of telemedicine in preventing multi-drug resistant tuberculosis (MDR-TB) in Nigeria. The specific objectives include examining the potential benefits of telemedicine, identifying the challenges associated with its implementation, and highlighting the importance of addressing infrastructure limitations and data privacy concerns.

Methods

This minireview is based on a comprehensive analysis of existing literature, including scholarly articles, and reports,. A systematic search was conducted using electronic databases, such as PubMed and Google Scholar, to identify relevant publications related to telemedicine and MDR-TB prevention in Nigeria. The selected articles were assessed for their relevance, and key findings were synthesized to provide an overview of the role of telemedicine in addressing the challenges of MDR-TB in Nigeria.

Results

The review demonstrates that telemedicine has the potential to significantly contribute to MDR-TB prevention efforts in Nigeria. The benefits of telemedicine include improved access to specialized care, enhanced patient adherence to treatment, and potential cost savings. However, challenges such as infrastructure limitations and data privacy concerns need to be addressed for successful implementation. Integrating telemedicine into the healthcare system has the potential to strengthen MDR-TB prevention, particularly in underserved areas, including within Nigeria. Specifically, the integration of telemedicine into the healthcare system can enhance access to specialized care, improve patient adherence, and potentially reduce costs associated with MDR-TB management.

Conclusions

Addressing infrastructure challenges, ensuring data privacy and security, and fostering trust among healthcare providers and patients are critical for successful implementation of telemedicine. Further research and policy frameworks are needed to guide the effective implementation and scale-up of telemedicine in MDR-TB prevention efforts in Nigeria.

Systems analysis and improvement approach to optimize tuberculosis (SAIA-TB) screening, treatment, and prevention in South Africa: a stepped-wedge cluster randomized trial

BACKGROUND

The use of systems engineering tools, including the development and use of care cascades using routinely collected data, process mapping, and continuous quality improvement, is used for frontline healthcare workers to devise systems level change. South Africa experiences high rates of tuberculosis (TB) infection and disease as well as HIV co-infection. The Department of Health has made significant gains in HIV services over the last two decades, reaching their set "90-90-90" targets for HIV. However, TB services, although robust, have lagged in comparison for both disease and infection. The Systems Analysis and Improvement Approach (SAIA) is a five-step implementation science method, drawn from systems engineering, to identify, define, and implement workflow modifications using cascade analysis, process mapping, and repeated quality improvement cycles within healthcare facilities.

METHODS

This stepped-wedge cluster randomized trial will evaluate the effectiveness of SAIA on TB (SAIA-TB) cascade optimization for patients with TB and high-risk contacts across 16 clinics in four local municipalities in the Sarah Baartman district, Eastern Cape, South Africa. We hypothesize that SAIA-TB implementation will lead to a 20% increase in each of: TB screening, TB preventive treatment initiation, and TB disease treatment initiation during the 18-month intervention period. Focus group discussions and key informant interviews with clinic staff will also be conducted to determine drivers of implementation variability across clinics.

DISCUSSION

This study has the potential to improve TB screening, treatment initiation, and completion for both active disease and preventive measures among individuals with and without HIV in a high burden setting. SAIA-TB provides frontline health care workers with a systems-level view of their care delivery system with the aim of sustainable systems-level improvements.

Analysing the progress in service delivery towards achieving universal health coverage in Nigeria: a scoping review

BACKGROUND

Attainment of universal health coverage (UHC) requires optimal utilization of health services. Poor coverage and inequitable access to healthcare could hinder improvement in service delivery towards UHC. The study analyzed the progress in service delivery coverage and equity in access to care within the Nigerian health systems based on the tracer indicators of the WHO framework for monitoring UHC.

METHODS

We searched the literature in databases: PubMed, Scopus, Directory of Open Access Journals, Google Scholar, Science Direct and websites of relevant health Ministries, Agencies, and Organizations between March to December 2022. Search terms were identified in four broader themes: Service delivery coverage, equity, UHC and Nigeria. Data were collected through a review of 37 published articles (19 peer-reviewed articles and 8 grey documents). We synthesized the findings in thematic areas using the WHO framework for monitoring UHC.

RESULTS

The findings show a slow improvement in service delivery coverage across the UHC tracer indicators; reproductive, maternal, newborn and child health, infectious diseases, non-communicable diseases and service capacity and access. With regards to equity in access to care across the tracer indicators, there has been a great disparity in the utilization of healthcare services among rural dwellers, lower educational level individuals and those with poor socio-economic status over 20 years. However, there was remarkable progress in the ownership and use of long-lasting insecticide-treated nets among rural and lowest-wealth quantile households than their urban counterpart.

CONCLUSION

There is poor coverage and persistent inequitable access to care among the tracer indicators for monitoring progress in service delivery. Attaining UHC requires concerted efforts and investment of more resources in service delivery to address inequitable access to care and sustainable service coverage for improved health outcomes.

Governance for injury care systems in Ghana, South Africa and Rwanda: development and pilot testing of an assessment tool

OBJECTIVES

This study aims to evaluate health systems governance for injury care in three sub-Saharan countries from policymakers' and injury care providers' perspectives.

SETTING

Ghana, Rwanda and South Africa.

DESIGN

Based on Siddiqi et al's framework for governance, we developed an online assessment tool for health system governance for injury with 37 questions covering health policy and implementation under 10 overarching principles of strategic vision, participation and consensus orientation, rule of law, transparency, responsiveness of institutions, equity, effectiveness or efficiency, accountability, ethics and intelligence and information. A literature review was also done to support the scoring. We derived scores using two methods-investigator scores and respondent scores.

PARTICIPANTS

The tool was sent out to purposively selected stakeholders, including policymakers and injury care providers in Ghana, Rwanda and South Africa. Data were collected between October 2020 and February 2021.

PRIMARY AND SECONDARY OUTCOMES

Investigator-weighted and respondent percentage scores for health system governance for injury care. This was calculated for each country in total and per principle.

RESULTS

Rwanda had the highest overall investigator-weighted percentage score (70%), followed by South Africa (59%). Ghana had the lowest overall investigator score (48%). The overall results were similar for the respondent scores. Some areas, such as participation and consensus, scored high in all three countries, while other areas, such as transparency, scored very low.

CONCLUSION

In this multicountry governance survey, we provide insight into and evaluation of health system governance for trauma in three low- and middle-income countries (LMICs) in sub-Saharan Africa. It highlights areas of improvement that need to be prioritised, such as transparency, to meet the high burden of trauma and injuries in LMICs.

Exploration of the diversity of multi-drug resistant Mycobacterium tuberculosis complex in Lagos, Nigeria using WGS: Distribution of lineages, drug resistance patterns and genetic mutations

Multidrug-resistant (MDR) or extensively drug-resistant (XDR) Tuberculosis (TB) is a major challenge to global TB control. Therefore, accurate tracing of in-country MDR-TB transmission are crucial for the development of optimal TB management strategies. This study aimed to investigate the diversity of MTBC in Nigeria. The lineage and drug-resistance patterns of the clinical MTBC isolates of TB patients in Southwestern region of Nigeria were determined using the WGS approach. The phenotypic DST of the isolates was determined for nine anti-TB drugs. The sequencing achieved average genome coverage of 65.99X. The most represented lineages were L4 (n = 52, 83%), L1 (n = 8, 12%), L2 (n = 2, 3%) and L5 (n = 1, 2%), suggesting a diversified MTB population. In term of detection of M/XDR-TB, while mutations in katG and rpoB genes are the strong predictors for the presence of M/XDR-TB, the current study also found the lack of good genetic markers for drug resistance amongst the MTBC in Nigeria which may pose greater problems on local tuberculosis management efforts. This high-resolution molecular epidemiological data provides valuable insights into the mechanistic for M/XDR TB in Lagos, Nigeria.

How to establishing an indicators framework for evaluating the performances in primary TB control institutions under the new TB control model? Based on a Delphi study conducted in Guangxi, China

BACKGROUND

In China, the new TB control model of trinity form had been implemented in all parts, and the comprehensively evaluation to the performances in primary TB control institutions were closely related to the working capacity and quality of TB service, but there was still no an unified evaluation indicators framework in practice and few relevant studies. The purpose of this study was to establish an indicators framework for comprehensively evaluating the performances in primary TB control institutions under the new TB control model of trinity form in Guangxi, China.

METHODS

The Delphi method was used to establish an indicators framework for comprehensively evaluating the performances in primary TB control institutions under the new TB control model of trinity form, and the analytic hierarchy process(AHP) was used to determine the weights of all levels of indicators, from September 2021 to December 2021 in Guangxi, China.

RESULTS

A total of 14 experts who had at least 10 years working experience and engaged in TB prevention and control and public health management from health committee, CDC, TB designated hospitals and university of Guangxi were consulted in two rounds. The average age of the experts were (43.3 ± 7.549) years old, and the effective recovery rate of the questionnaire was 100.0%. The average value of authority coefficient of experts (Cr) in the two rounds of consultation was above 0.800. The Kendall's harmony coefficient (W) of experts' opinions on the first-level indicators, the second-level indicators and the third-level indicators were 0.786, 0.201 and 0.169, respectively, which were statistically significant (P < 0.05). Finally, an indicators framework was established, which included 2 first-level indicators, 10 second-level indicators and 37 third-level indicators. The results of analytic hierarchy process (AHP) showed that the consistency test of all levels of indicators were CI < 0.10, which indicating that the weight of each indicator was acceptable.

CONCLUSION

The indicators framework established in this study was in line with the reality, had reasonable weights, and could provide a scientific evaluation tool for comprehensively evaluating the performances in primary TB control institutions under the new TB control model of trinity form in Guangxi, China.

Governance Efforts for TB-Friendly Village Development during the COVID-19 Pandemic: Lessons Learned from Depok City, West Java, Indonesia

BACKGROUND: In 2020, TB patients in Indonesia reached 8.5% of the total number of TB patients globally, as the country with the second-highest TB cases. Depok is the city in the West Java region that has experienced an increase in TB cases. The existence of tuberculosis-friendly villages will reduce the stigmatization of tuberculosis (TB) patients and increase treatment compliance. AIM: This study aims to analyze various aspects of Depok City’s readiness to develop TB-friendly village governance –– including government commitment, infrastructure, resources, and organizational culture –– within the scope of academic, business, community, government, and media (ABCGM)’s role or penta-helix. METHODS: The initial stage of preparation involved conducting a literature review. This research employed an online survey of 230 respondents and 40 TB patients using a quantitative approach. The qualitative approach involved 15 stakeholders through interviews, discussions, and a website-based search. RESULTS: Overall, the respondents were well-informed about TB, but attitudes (50.9%) and behavior (41.3%) regarding TB prevention need improvement. The government budget is adequate, but coordination is lacking between stakeholders and community involvement. CONCLUSION: Depok City is not yet ready to develop TB-friendly villages in terms of human resources and organizational aspects. It is necessary to improve communication, information, and education regarding TB prevention and establish leadership policies as a legal basis to strengthen the governance and management of TB-friendly villages. Moreover, community involvement is an essential pillar of developing these villages.

Do private health providers adhere to National Tuberculosis Guideline while assigning treatment outcome? Findings from a lower middle-income country

Background

Treatment success rate is an important indicator to measure the performance of the National Tuberculosis Program (NTP). There are concerns about the quality of outcome data from private facilities engaged by NTP. Adherence of private providers of tuberculosis care to NTP guideline while assigning treatment outcomes to patients is rarely investigated. We aimed to determine whether Lagos private for-profit (PFP) and private not-for-profit (PNFP) facilities adhere to domestic TB guideline while assigning treatment outcome and the availability of periodic sputum acid-fast bacilli (AFB) results.

Method

A retrospective review of facility treatment register and treatment cards of TB patients managed between January and December 2016 across 10 private directly observed treatment short-course (DOTS) facilities involved in the public-private mix (PPM) in Lagos, Nigeria. The study took place between January and June 2019.

Results

Of the 1,566 patients, majority (60.7%) were male, >30 years (50.2%), HIV-negative (88.4%), and attended PNFP (78.5%). The reported treatment success rate (TSR) was 84.2% while the actual TSR was 53.8%. In total, 91.1, 77.6, and 70.3% of patients had sputum acid-fast bacilli (AFB) at 2/3, month 5, and month 6, respectively, while 68.6% had all the three sputum AFB in the register. Healthcare workers (HCWs) were adherent in assigning treatment outcome for 65.6% of TB patients while 34.4% of patients were assigned incorrect treatment outcomes. Most variations between reported and actual treatment outcomes were found with cured (17%) and completed (13.4%). Successful and unsuccessful outcomes were overreported by 30.4% and 4.1%, respectively. DOTS providers in private facilities with available TB guideline (OR 8.33, CI 3.56-19.49, p < 0.0001) and PNFP facility (OR 4.42, CI 1.91-10.3, p = 0.001) were more likely to adhere to National TB Guideline while assigning TB treatment outcome.

Conclusion

Frontline TB providers in Lagos private hospitals struggled with assigning correct treatment outcome for TB patients based on NTBLCP guideline. Increased access to all the periodic follow-up AFB tests for TB patients on treatment and availability of National TB Guideline for referencing could potentially improve the adherence of private TB service providers while assigning TB treatment outcomes.

Enhancing Tuberculosis Case-Finding: A Case of Quality Improvement Initiative in Tanzania

Background: Tanzania is 1 of the 30 high TB burden countries and 1 of the 13 countries in which 75% of people with TB are unaccounted for and that is prioritized for the Global Fund Catalytic investment and Strategic Initiative support. Tanzania decided to strengthen its National TB Programme to find these people with TB who are unaccounted for by identifying evidence-driven innovations to deliver high-quality services and to improve the efficiency of TB case-finding. A quality improvement (QI) initiative was implemented by the National Tuberculosis and Leprosy Programme to enhance TB case-finding. The initiative involved identifying gaps in the quality of services, introducing new tools, improving the work capacity of health care workers through training and mentorship sessions, strengthening laboratory and referral services, and implementing mandatory TB screening of all patients attending health facilities. We aimed to assess the effectiveness of QI initiative to enhance TB case-findings at the health facility level. Method: A cross-sectional design, and intervention and control facilities randomly selected for an evaluation of the QI initiative were used. Twenty facilities from the Dodoma region across all health care system levels (dispensaries, health centres, and hospitals) were involved in this evaluation. The facilities were randomly divided into either the intervention or control groups at a 1:1 ratio (10 intervention and 10 control facilities). Data routinely collected from program registers from January 2016 to June 2017 were used. Result: The evaluation registered a 52% increase in TB case notification in Q1 of 2017 compared with in Q1 of 2016 and, similarly, a 52% increase in Q2 of 2017 compared with in Q2 of 2016, with 9 out of 10 intervention sites reporting increases in their quarterly TB case notifications. There were no positive changes in the ‘control facilities’ where routine services were provided, with half of the facilities showing a decrease in TB case notification from baseline. Conclusion: This QI initiative has the potential to support a long-term comprehensive approach to ending TB and to improve the quality of the foundations of the health care system. This initiative sets a reliable pace for health facilities to efficiently respond to and manage TB case-finding interventions put into action. Tanzania’s experience with implementing QI interventions could serve as a model for improving TB case notifications in other settings.

Integration of systematic screening for tuberculosis in outpatient departments of urban primary healthcare facilities in Zambia: a case study of Kitwe district

Background

Tuberculosis (TB) is the leading cause of death from a single infectious agent globally, killing about 1.5 million people annually, yet 3 million cases are missed every year. The World Health Organization recommends systematic screening of suspected active TB patients among those visiting the healthcare facilities. While many countries have scaled-up systematic screening of TB, there has been limited assessment of the extent of its integration into the health system. This study sought to explore factors that shape the integration of systematic screening of TB in outpatient departments of primary healthcare facilities in Kitwe district, Zambia.

Methods

This was a qualitative case study with health providers including district managers, TB focal point persons and laboratory personnel working in six purposively selected primary healthcare facilities. Data was collected through key informant (n = 8) and in-depth (n = 15) interviews. Data analysis was conducted using QDA Miner software and guided by Atun’s Integration framework.

Results

The facilitators to integration of systematic screening for TB into out patient departments of primary health facilities included the perceived high burden TB, compatibility of the systematic screening for TB program with healthcare workers training and working schedules, stakeholder knowledge of each others interest and values, regular performance management and integrated outreach of TB screening services. Constraining factors to integration of systematic screening for TB into outpatient departments included complexity of screening for TB in children, unbalanced incentivization mechanisms, ownership and legitimacy of the TB screening program, negative health worker attitudes, social cultural misconceptions of TB and societal stigma as well as the COVID-19 pandemic.

Conclusion

Systematic screening of TB is not fully integrated into the primary healthcare facilities in Zambia to capture all those suspected with active TB that make contact with the health system. Finding the missing TB cases will, therefore, require contextual adaptation of the systematic screening for TB program to local needs and capacities as well as strengthening the health system.

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.

Tuberculosis Treatment Outcome and Predictors in Africa: A Systematic Review and Meta-Analysis

This review aimed to summarize and estimate the TB treatment success rate and factors associated with unsuccessful TB treatment outcomes in Africa. Potentially eligible primary studies were retrieved from PubMed and Google Scholar. The risk of bias and quality of studies was assessed using The Joanna Briggs Institute's (JBI) appraisal criteria, while heterogeneity across studies was assessed using Cochran's Q test and I2 statistic. Publication bias was checked using the funnel plot and egger's test. The protocol was registered in PROSPERO, numbered CRD42019136986. A total of 26 eligible studies were considered. The overall pooled estimate of TB treatment success rate was found to be 79.0% (95% CI: 76-82%), ranging from 53% (95% CI: 47-58%) in Nigeria to 92% (95% CI: 90-93%) in Ethiopia. The majority of unsuccessful outcomes were attributed to 48% (95% CI: 40-57%) death and 47% (95% CI: 39-55%) of defaulter rate. HIV co-infection and retreatment were significantly associated with an increased risk of unsuccessful treatment outcomes compared to HIV negative and newly diagnosed TB patients with RR of 1.53 (95% CI: 1.36-1.71) and 1.48 (95% CI: 1.14-1.94), respectively. TB treatment success rate was 79% below the WHO defined threshold of 85% with significant variation across countries. Countries need to explore contextual underlining factors and more effort is required in providing TB preventive treatment, improve case screening and linkage for TB treatment among HIV high-risk groups and use confirmatory TB diagnostic modality. Countries in Africa need to strengthen counseling and follow-up, socio-economic support for patients at high risk of loss to follow-up and poor treatment success is also crucial for successful TB control programs.

Treatment outcomes among tuberculosis patients in Jeddah, Saudi Arabia: Results of a community mobile outreach directly observed Treatment, Short-course (DOTS) project, compared to a standard facility-based DOTS: A randomized controlled trial

INTRODUCTION

Tuberculosis (TB) remains a global public health threat affecting people in many developing countries, including the Kingdom of Saudi Arabia. Maintaining a long-term treatment regimen has always been the cornerstone of successful treatment outcomes among tuberculosis patients. In the Jeddah region, the National Tuberculosis Control and Prevention Program is now treating TB patients by means of a community mobile outreach team approach.The objective of this study was to compare the effectiveness of the community mobile outreach approach in improving treatment outcomes (success rate) among local tuberculosis patients with those being treated with a facility-based directly observed treatment, short-course (DOTS).

STUDY DESIGN

Our study consisted of a two-sample, parallel design [1:1], statistician -blind randomized control trial with 200 newly diagnosed, TB patients as subjects.

SETTING/PARTICIPANTS

The patients had all presented at the Madain Alfahd Primary Health Care Center, Jeddah. Between Nov 2017 and Nov 2018, a total of 221 TB patients were screened of whom 200 were randomly selected using randomly generated sequences.

INTERVENTION

Patients in the intervention sample group were treated by means of mobile outreach teams with oral anti-TB treatment under the DOTS, and control group patients were given the traditional facility-based DOTS treatment according to the WHO recommendations and national guidelines.

MAIN OUTCOME

The primary outcome was the level of overall treatment success rate. It was finally determined and compared in the two sample groups using chi-square analysis and relative risk assessment.

RESULTS

In the analysis stage, 97 patients were in the intervention group, while the control group consisted of 76. The overall response rate was 86.5% (173/200). We found that the percentage of overall treatment success rate among the patients served by the mobile outreach team was 97%, compared to 76% in the non-mobile team treated patients. The relative risk of treatment success rate among the intervention group was 1.27 (95% CI = 1.13-1.43) times greater than that amongst the control group. Log-rank test (log-rank statistics = 18.91; p < 0.001) identified a significant difference in the default rate after six months of treatment.

CONCLUSION

This study has shown that a mobile outreach DOTS approach is an effective and acceptable strategy for treating TB patients. It also provides important data on the efficacy of using mobile outreach teams to improve TB treatment outcomes in Jeddah. Our results provide evidence and highlight the positive and significant impact of mobile outreach teams in mitigating TB recurrence rates and in improving TB treatment outcomes.Clinical Trial Registration: Clinicaltrials.gov: NCT03787914.

Tuberculosis treatment outcomes and associated factors in two states in Nigeria

OBJECTIVE

To determine the treatment success rate among TB patients and associated factors in Anambra and Oyo, the two states with the largest burden of tuberculosis in Nigeria.

METHODS

A health facility record review for 2016 was conducted in the two states (Anambra and Oyo). A checklist was used to extract relevant information from the records kept in each of the selected DOTS facilities to determine TB treatment success rates. Treatment success rate was defined as the proportion of new smear-positive TB cases registered under DOTS in a given year that successfully completed treatment, whether with bacteriologic evidence of success ('cured') or without ('treatment completed'). Treatment success rate was classified into good (≥85%) and poor (<85%) success rates using the 85% national target for TB treatment outcome. Data were analysed using descriptive statistics and chi-square at P < 0.05.

RESULTS

There were 1281 TB treatment enrollees in 2016 in Anambra and 3809 in Oyo (total = 4835). An overall treatment success rate of 75.8% was achieved (Anambra-57.5%; Oyo-82.0%). The percentage cure rates were 61.5% for Anambra and 85.2% for Oyo. Overall, only 28.6% of the facilities in both states (Anambra-0.0%; Oyo-60.0%) had a good treatment success rate. More facilities in Anambra (100.0%) than Oyo (40.0%) had a poor treatment success rate (p < 0.001), as did more private/FBO (100.0%) than public health facilities (60.0%) (p = 0.009). All tertiary facilities had a poor treatment success rate followed by 87.5% of secondary health facilities and 56.5% of primary healthcare facilities (P = 0.035).

CONCLUSION

Treatment success and cure rates in Anambra state were below the 85.0% of the recommended target set by the WHO. Geographical location, and level/tier and type of facility were factors associated with this. Interventions are recommended to address these problems.

In-silico Molecular Docking and ADME/Pharmacokinetic Prediction Studies of Some Novel Carboxamide Derivatives as Anti-tubercular Agents

Molecular docking simulation of thirty-five (35) molecules of N-(2-phenoxy)ethyl imidazo[1,2-a]pyridine-3-carboxamide (IPA) with Mycobacterium tuberculosis target (DNA gyrase) was carried out so as to evaluate their theoretical binding affinities. The chemical structure of the molecules was accurately drawn using ChemDraw Ultra software, then optimized at density functional theory (DFT) using Becke’s three-parameter Lee–Yang–Parr hybrid functional (B3LYP/6-311**) basis set in a vacuum of Spartan 14 software. Subsequently, the docking operation was carried out using PyRx virtual screening software. Molecule 35 (M35) with the highest binding affinity of − 7.2 kcal/mol was selected as the lead molecule for structural modification which led to the development of four (4) newly hypothetical molecules D1, D2, D3 and D4. In addition, the D4 molecule with the highest binding affinity value of − 9.4 kcal/mol formed more H-bond interactions signifying better orientation of the ligand in the binding site compared to M35 and isoniazid standard drug. In-silico ADME and drug-likeness prediction of the molecules showed good pharmacokinetic properties having high gastrointestinal absorption, orally bioavailable, and less toxic. The outcome of the present research strengthens the relevance of these compounds as promising lead candidates for the treatment of multidrug-resistant tuberculosis which could help the medicinal chemists and pharmaceutical professionals in further designing and synthesis of more potent drug candidates. Moreover, the research also encouraged the in vivo and in vitro evaluation study for the proposed designed compounds to validate the computational findings.

Through service providers' eyes: health systems factors affecting implementation of tuberculosis control in Enugu State, South-Eastern Nigeria

Background

Well-functioning health systems are essential to achieving global and national tuberculosis (TB) control targets. This study examined health system factors affecting implementation of TB control programme from the perspectives of service providers.

Methods

The study was conducted in Enugu State, South-eastern Nigeria using qualitative, cross-sectional design involving 23 TB service providers (13 district TB supervisors and 10 facility TB focal persons). Data were collected through in-depth, semi-structured interviews using a health system dynamic framework and analysed thematically.

Results

Stewardship from National TB Control Programme (NTP) improved governance of TB control, but stewardship from local government was weak. Government spending on TB control was inadequate, whereas donors fund TB control. Poor human resources management practices hindered TB service delivery. TB service providers have poor capacity for data management because changes in recording and reporting tools were not matched with training of service providers. Drugs and other supplies to TB treatment centres were interrupted despite the use of a logistics agency. Poor integration of TB into general health services, weak laboratory capacity, withdrawal of subsidies to community volunteers and patent medicine vendors, poorly funded patient tracking systems, and ineffectual TB/HIV collaboration resulted in weak organisation of TB service delivery.

Conclusion

Health systems strengthening for TB control service must focus on effective oversight from NTP and local health system; predictable domestic resource mobilisation through budgets and social health insurance; training and incentives to attract and retain TB service providers; effective supply and TB drug management; and improvements in organization of service delivery.
