Nigeria as a Case Study

AI co-pilot bronchoscope robot

The unequal distribution of medical resources and scarcity of experienced practitioners confine access to bronchoscopy primarily to well-equipped hospitals in developed regions, contributing to the unavailability of bronchoscopic services in underdeveloped areas. Here, we present an artificial intelligence (AI) co-pilot bronchoscope robot that empowers novice doctors to conduct lung examinations as safely and adeptly as experienced colleagues. The system features a user-friendly, plug-and-play catheter, devised for robot-assisted steering, facilitating access to bronchi beyond the fifth generation in average adult patients. Drawing upon historical bronchoscopic videos and expert imitation, our AI-human shared control algorithm enables novice doctors to achieve safe steering in the lung, mitigating misoperations. Both in vitro and in vivo results underscore that our system equips novice doctors with the skills to perform lung examinations as expertly as seasoned practitioners. This study offers innovative strategies to address the pressing issue of medical resource disparities through AI assistance.

Health Equity and Respiratory Diseases in Low- and Middle-Income Countries

Over 80% of the morbidity and mortality related to acute and chronic respiratory diseases occur in low- and middle-income countries (LMICs), a reflection of vast disparities in care for these conditions. Over the next decade, the prevalence of respiratory diseases is expected to increase, as population growth in LMICs exceeds high-income countries (HICs). Pediatric morbidity and mortality from lower respiratory tract infections and asthma occur almost exclusively in LMICs, contributing to a greater loss of quality adjusted life years from these conditions when compared with HICs.

A Longitudinal Study of Multimodal Bronchoscopy Training in Uganda

Background

Flexible bronchoscopy is an essential tool in diagnosing and managing pulmonary diseases. However, there is limited capacity for bronchoscopy in low and middle income countries (LMICs). In 2019, a pilot program for flexible bronchoscopy training was launched for local physicians in Kampala, Uganda. We then conducted a follow up multimodal bronchoscopy course after 2 years.

Objective

The aim of this study is to assess a longitudinal multimodal bronchoscopy training in an LMIC setting.

Methods

A multimodal follow up curriculum was developed with pulmonologists from Uganda and the United States. The training was delivered to Ugandan providers who attended previous bronchoscopy training and new participants. The training included a prepared curriculum consisting of lectures, simulations, and deliberate practice-based proctoring. A 12-question multiple-choice exam was administered at the beginning and end of the course, assessing knowledge. Procedural competency was measured using a validated assessment tool called the BSTAT (Bronchoscopic Skills and Tasks Assessment Tool). Results were analyzed to evaluate the retention of knowledge among those who took part in previous training and the efficacy of the follow-up curriculum for participants without previous training.

Results

Among the participants who attended didactic training in 2022 (11), mean exam scores were improved after training, from 43.9 (standard deviation [SD], 11.3) to 59.8 (SD, 16.1) (mean difference [MD], +15.9; SD, 13.9; P = 0.008), but were lower compared with post didactic scores in 2019: 90.8 (SD, 6.1; MD, -31; P < 0.0001). Participants who completed BSTAT assessments (8) had mean scores similar in 2019 and 2022, at 72.1 and 75.2, respectively (MD, 3.1; P = 0.38).

Conclusion

This study provides an example of how a longitudinal multimodal bronchoscopy curriculum can improve competency and proficiency for local physicians in an LMIC.

Challenges in the diagnosis of asthma in children, what are the solutions? A scoping review of 3 countries in sub Saharan Africa

Background

Asthma is the commonest chronic respiratory tract disease in children. In low-income countries, challenges exist in asthma diagnosis. In surveys done in children, the prevalence of ‘asthma’ defined by symptoms is high compared to ‘doctor diagnosed asthma’. The questions answered by this review are (i) What challenges have been experienced in the diagnosis of asthma in children? (ii) What solutions will address these challenges?

Methods

The Arksey and O’Malley’s framework for scoping reviews was used for the study methodology, while the PRISMA-ScR checklist guided the reporting process. Electronic databases: PubMed Central, EMBASE and Google Scholar were searched. Primary quantitative and qualitative studies and reviews from 2010 to 2021, from Nigeria, South Africa and Uganda written in English or translated to English, which answered the study questions were included. The author, title, country, study type, methods, purpose, findings and references were captured onto a predefined data collection table. The ‘Preview, Question, Read, Summarise’ system was used and a narrative report was used to summarise the findings.

Results

A total of 28 studies were included. The causes of under-diagnosis of asthma include lack of community knowledge and perception of asthma, poor accessibility to health care, strained health systems, lack of diagnostic tests including spirometry, low levels of knowledge among health-care workers and lack of or non-implementation of asthma guidelines. Strategies to improve asthma diagnosis will include community and school based education programmes, revision of asthma diagnostic terms, guideline development and implementation and health systems strengthening.

Conclusion

This scoping review provides research evidence for policy makers and health-workers involved in the care of asthmatic children on challenges faced in asthma diagnosis and strategies to improve asthma diagnosis.

Surgical Capacity Building in Low- and Middle-Income Countries: Lessons for Thoracic Surgery

There is great need for intentional investment in capacity building for thoracic surgical conditions. This article provides a brief overview of thoracic surgical capacity building for low- and middle-income countries using the Lancet framework of infrastructure, workforce, financing, and information management. The authors highlight the needs, opportunities, and challenges that are relevant for the thoracic surgical community, as it aims to increase care for patients with these conditions globally.

Revamping of Chronic Respiratory Diseases in Low- and Middle-Income Countries

Low- and middle-income countries (LMICs) endure an asymmetrically high burden of worldwide disease and death caused by chronic respiratory diseases (CRDs), i.e., asthma, emphysema, bronchiectasis, and post-tuberculosis lung disease (PTLD). CRDs are firmly related with indigence, infectious diseases, and other non-communicable diseases (NCDs) and add to complex multi-disease with great impact on the lives and livelihood of those affected. The pertinence of CRDs to health and demographic wellbeing is relied upon to increment in the long time ahead, as expectations of life rise and the contending dangers of right on time youth mortality and irresistible infections level. The WHO has distinguished the counteraction and control of NCDs as an earnest improvement issue and crucial for the sustainable development goals (SDSs) by 2030. In this review, we center on CRDs in LMICs. We examine the early life roots of CRDs, challenges in their avoidance, identification and administration in LMICs, and the pathways to resolve for accomplish valid widespread wellbeing inclusion.

Improving lung health in low-income and middle-income countries: from challenges to solutions

Low-income and middle-income countries (LMICs) bear a disproportionately high burden of the global morbidity and mortality caused by chronic respiratory diseases (CRDs), including asthma, chronic obstructive pulmonary disease, bronchiectasis, and post-tuberculosis lung disease. CRDs are strongly associated with poverty, infectious diseases, and other non-communicable diseases (NCDs), and contribute to complex multi-morbidity, with major consequences for the lives and livelihoods of those affected. The relevance of CRDs to health and socioeconomic wellbeing is expected to increase in the decades ahead, as life expectancies rise and the competing risks of early childhood mortality and infectious diseases plateau. As such, the World Health Organization has identified the prevention and control of NCDs as an urgent development issue and essential to the achievement of the Sustainable Development Goals by 2030. In this Review, we focus on CRDs in LMICs. We discuss the early life origins of CRDs; challenges in their prevention, diagnosis, and management in LMICs; and pathways to solutions to achieve true universal health coverage.

Availability of diagnostic services and essential medicines for non-communicable respiratory diseases in African countries

BACKGROUND: The global burden of disease due to asthma and chronic obstructive pulmonary disease (COPD) is substantial and particularly great in low- and middle-income countries, including many African countries. Management is affected by availability of diagnostic tests and essential medicines. The study aimed to explore the availability of spirometry services and essential medicines for asthma and COPD in African countries.METHOD: Questionnaires were delivered to healthcare workers at the annual meeting of the Pan African Thoracic Society Methods in Epidemiology and Clinical Research (PATS MECOR) and International Multidisciplinary Programme to Address Lung Health and TB in Africa (IMPALA). Data were analysed using simple descriptive statistics.RESULTS: A total of 37 questionnaires representing 13 African countries were returned. Spirometry availability was 73.0%. The most common reasons for non-availability were lack of knowledge of the utility of the test. Within the study sample, 33.3% faced sporadic availability due to maintenance issues. Essential medicines availability ranged from 37.8% for inhaled corticosteroid-long-acting beta-agonist inhalers to 100% for prednisolone 5 mg tablets, mainly due to supply chain problems.CONCLUSION: There is varied availability of spirometry and WHO essential medicines for COPD and asthma in African countries. Strategies are needed to improve access to basic effective care for people with non-communicable lung disease in Africa.

A Pilot Program Assessing Bronchoscopy Training and Program Initiation in a Low-income Country

BACKGROUND

Flexible bronchoscopy is an essential procedure for the evaluation and management of the pulmonary disease. However, this technology and related training is not available in many low-middle income countries (LMICs). We conducted a pilot training program for flexible bronchoscopy in Uganda.

METHODS

A multimodal curriculum was developed with pulmonologists from Uganda and the United States. The training included an online distance learning management system for video content, simulation, just-in-time training, and deliberate practice via clinical proctoring. Procedural standards and a de novo bronchoscopy suite were concurrently developed. Competency was assessed using the Bronchoscopic Skills and Tasks Assessment Tool written examination and the Ontario Bronchoscopy Assessment Tool.

RESULTS

We trained 3 pulmonary physicians with no prior experience in flexible bronchoscopy. Three bronchoscopies with bronchoalveolar lavage were performed during the training and an additional 11 cases were performed posttraining. All 3 Ugandan physicians had an increase in their written Bronchoscopic Skills and Tasks Assessment Tool and Ontario Bronchoscopy Assessment Tool in the competent range (P<0.05). All bronchoscopies were successfully completed, adequate samples were obtained, and there were no procedure-related complications.

CONCLUSION

Bronchoscopy implementation in LMICs is feasible, but requires competency-based training. Further studies are needed to validate this curriculum in LMICs, including the use of this type of curriculum for more complicated bronchoscopic procedures.

General Thoracic Surgery in Rwanda: An Assessment of Surgical Volume and of Workforce and Material Resource Deficits

BACKGROUND

Benchmarking operative volume and resources is necessary to understand current efforts addressing thoracic surgical need. Our objective was to examine the impact on thoracic surgery volume and patient access in Rwanda following a comprehensive capacity building program, the Human Resources for Health (HRH) Program, and thoracic simulation training.

METHODS

A retrospective cohort study was conducted of operating room registries between 2011 and 2016 at three Rwandan referral centers: University Teaching Hospital of Kigali, University Teaching Hospital of Butare, and King Faisal Hospital. A facility-based needs assessment of essential surgical and thoracic resources was performed concurrently using modified World Health Organization forms. Baseline patient characteristics at each site were compared using a Pearson Chi-squared test or Kruskal-Wallis test. Comparisons of operative volume were performed using paired parametric statistical methods.

RESULTS

Of 14,130 observed general surgery procedures, 248 (1.76%) major thoracic cases were identified. The most common indications were infection (45.9%), anatomic abnormalities (34.4%), masses (13.7%), and trauma (6%). The proportion of thoracic cases did not increase during the HRH program (2.07 vs 1.78%, respectively, p = 0.22) or following thoracic simulation training (1.95 2013 vs 1.44% 2015; p = 0.15). Both university hospitals suffer from inadequate thoracic surgery supplies and essential anesthetic equipment. The private hospital performed the highest percentage of major thoracic procedures consistent with greater workforce and thoracic-specific material resources (0.89% CHUK, 0.67% CHUB, and 5.42% KFH; p < 0.01).

CONCLUSIONS AND RELEVANCE

Lack of specialist providers and material resources limits thoracic surgical volume in Rwanda despite current interventions. A targeted approach addressing barriers described is necessary for sustainable progress in thoracic surgical care.

Dealing with Access to Spirometry in Africa: A Commentary on Challenges and Solutions

Spirometry is an important tool in the surveillance, epidemiology, diagnosis, and management of respiratory disease, yet its accessibility is currently limited in Africa where the burden of respiratory diseases is amongst the highest globally. The reasons for limited access to spirometry in Africa include poor access to training and skilled technicians, limited availability of equipment, consumables, and technical support, and lack of human and financial resources. The Pan African Thoracic Society, working together with regional African thoracic societies and key research initiatives in Africa, have made progress in training and education, but a lot of work is still needed to meet the challenges faced. Accurately defining these challenges of access to high quality spirometry, development of local, standardised, and context-specific training and quality assurance tools; development of appropriate reference standards and innovative approaches to addressing the challenges of access to equipment, consumables and technical support are needed. Training and research collaborations that include regional thoracic societies, health system leaders, the Pan African Thoracic Society and international role players in the field are key to maximising available intellectual and financial resources. Hence ensuring that access to high quality spirometry measures that are used effectively in tackling the burden of respiratory disease in Africa.

Bronchoscopy in Nigerian Clinical Practice: A Survey of Medical Doctors' Perception, Use and Associated Challenges

Background

Bronchoscopy is a vital diagnostic and therapeutic procedure in pulmonological practice. The aim of this study was to determine the perception, use and challenges encountered by Nigerian medical doctors involved in this procedure.

Materials and Methods

A cross-sectional study was conducted among 250 medical doctors recruited from three major tertiary institutions in Nigeria between September 2013 and June 2014. A semi-structured questionnaire was self-administered to adult physicians, paediatricians, and surgeons as well as their trainees to obtain their perception, use and associated challenges in the use of bronchoscopy in clinical practice.

Results

The majority (91.6%) of the respondents perceived bronchoscopy as a beneficial procedure to respiratory medicine. However, 59.2% of them were not aware of the low mortality rate associated with this procedure. The commonest indications for bronchoscopic use were foreign body aspiration (88.8%) and management of lung tumors (75.6%). Only 21 (8.4%) of the respondents had received formal training in bronchoscopy. Very few procedures (1–5 cases per month) were performed. The respondents identified the lack of formal training in the art of bronchoscopy as the foremost challenge facing its practice in Nigeria. In addition, availability of bronchoscopes, level of awareness, knowledge of the procedure among medical doctors and the cost of the procedure were the challenges faced by the medical doctors.

Conclusion

There is an urgent need to equip training centers with modern bronchoscopic facilities. In addition,well-structured bronchoscopic training programme is imperative to enhance the trainees' proficiency for the furtherance of bronchoscopic practice.

Access to affordable medicines and diagnostic tests for asthma and COPD in sub Saharan Africa: the Ugandan perspective

Background

Equitable access to affordable medicines and diagnostic tests is an integral component of optimal clinical care of patients with asthma and chronic obstructive pulmonary disease (COPD). In Uganda, we lack contemporary data about the availability, cost and affordability of medicines and diagnostic tests essential in asthma and COPD management.

Methods

Data on the availability, cost and affordability of 17 medicines and 2 diagnostic tests essential in asthma and COPD management were collected from 22 public hospitals, 23 private and 85 private pharmacies. The percentage of the available medicines and diagnostic tests, the median retail price of the lowest priced generic brand and affordability in terms of the number of days’ wages it would cost the least paid public servant were analysed.

Results

The availability of inhaled short acting beta agonists (SABA), oral leukotriene receptor antagonists (LTRA), inhaled LABA-ICS combinations and inhaled corticosteroids (ICS) in all the study sites was 75%, 60.8%, 46.9% and 45.4% respectively. None of the study sites had inhaled long acting anti muscarinic agents (LAMA) and inhaled long acting beta agonist (LABA)-LAMA combinations. Spirometry and peak flow-metry as diagnostic tests were available in 24.4% and 6.7% of the study sites respectively. Affordability ranged from 2.2 days’ wages for inhaled salbutamol to 17.1 days’ wages for formoterol/budesonide inhalers and 27.8 days’ wages for spirometry.

Conclusion

Medicines and diagnostic tests essential in asthma and COPD care are not widely available in Uganda and remain largely unaffordable. Strategies to improve access to affordable asthma and COPD medicines and diagnostic tests should be implemented in Uganda.

The East African Training Initiative. A Model Training Program in Pulmonary and Critical Care Medicine for Low-Income Countries

Despite an extensive burden of lung disease in East Africa, there are remarkably few pulmonary physicians in the region and no pulmonary subspecialty training programs. We developed a unique training program for pulmonary medicine in Ethiopia. The East African Training Initiative (EATI) is a 2-year fellowship program at Tikur Anbessa (Black Lion) Specialized Teaching Hospital, the largest public hospital in Ethiopia and the teaching hospital for the Addis Ababa University School of Medicine. The first year is devoted to clinical care and procedural skills. Lectures, conferences, daily inpatient and outpatient rounds, and procedure supervision by visiting faculty provide the clinical knowledge foundation. In the second year, training in clinical research is added to ongoing clinical training. Before graduation, fellows must pass rigorous written and oral examinations and achieve high marks on faculty evaluations. Funding derives from several sources. Ethiopian trainees are paid by the Ethiopian Ministry of Health and the Addis Ababa University School of Medicine. The World Lung Foundation and the Swiss Lung Foundation supply travel and housing costs for visiting faculty, who receive no other stipend. The first two trainees graduated in January 2015, and a second class of three fellows completed training in January 2016. All five presented research abstracts at the annual meetings of the International Union Against Tuberculosis and Lung Disease in 2014 and 2015. The EATI has successfully provided pulmonary medicine training in Ethiopia and has capacity for local leadership. We believe that EATI could be a model for other resource-limited countries.
