Background: Chronic obstructive pulmonary disease is one of the world’s leading causes of morbidity and mortality, with many low- and middle-income countries still experiencing an increase. Effective management requires a strong primary healthcare system, to prevent, diagnose in a timely way, and manage prevalent disease for a long period of time through to end of life, but this is inadequate in many middle-income countries.
The Breathe Well programme was a multinational collaboration between the University of Birmingham, United Kingdom, and partner institutions in four middle-income countries: Brazil, China, Georgia and North Macedonia. This review, conducted at the start of the programme, aimed to set the context for our research programme and future research, health care and policy needs by describing these four national health systems, risk factors, current burden and management of chronic obstructive pulmonary disease patients.
Design and methods: A descriptive review based on publicly available data identified from MEDLINE, national and international websites, supplemented by local expert opinion. For each of the included middle-income countries, we present and discuss the ability of the healthcare systems to effectively diagnose and manage chronic obstructive pulmonary disease, the barriers and limitations, including history of the healthcare system, organisation and governance, financing and medicines. The health and health care of chronic obstructive pulmonary disease patients are further illustrated by a hypothetical patient case developed with local clinical experts.
Results: While the sizes and features of the populations differ, the number of doctors tends to be low across most countries, the number of smokers high, the out-of-pocket expenses also high and the provision of diagnosis and management for chronic obstructive pulmonary disease in primary care suboptimal. Primary prevention including smoking cessation is insufficient across the participating countries. Cost and availability of care and medications are common barriers to effective chronic obstructive pulmonary disease management.
Limitations: This study is not a comprehensive systematic review. It provides a useful broad description of the subject, but we did not seek to produce detailed accounts.
Discussion: While there is vast diversity in settings and context, some challenges appeared to be shared: a lack of human and material resources in the primary care systems with an apparent power imbalance between primary and secondary care, pushing care burden to secondary care and potentially worsening geographic and economic health inequities. High cost (relative to average earnings) and low accessibility of long-term medications lead to high out-of-pocket expenditure, affecting quality and equity. There is generally suboptimal primary prevention with high smoking rates and high levels of air pollution. Improvement of prevention, diagnosis and management of chronic obstructive pulmonary disease via stronger primary care could help reduce health inequalities.
Future work: This study provided useful context for prioritising research questions within the Breathe Well programme and beyond. Research recommendations included assessment of resource-effective methods for primary prevention, screening and community-led management of chronic obstructive pulmonary disease cases, as well as mapping the educational needs of primary care staff which were then prioritised by local stakeholders including patients, clinicians, healthcare managers and policy-makers. It will be essential to update information on local context at regular intervals to ensure currency of research plans.

Chronic obstructive pulmonary disease is a common cause of lung disease across the world which is mainly caused by cigarette smoking and from breathing polluted air. As chronic obstructive pulmonary disease typically is a lifelong condition and affects many parts of daily life, effective treatment requires a strong healthcare system. This includes preventing the development of chronic obstructive pulmonary disease in the first place, for example through reducing smoking rates, diagnosing chronic obstructive pulmonary disease in those affected and providing the right treatment at a cost acceptable to patients with different circumstances.
The Breathe Well programme was a collaboration between researchers from four middle-income countries: Brazil, China, Georgia and North Macedonia, with the aim to learn from each other and improve chronic obstructive pulmonary disease management. As part of this programme, this review was carried out to summarise the needs of the different care systems, find common grounds for research and guide the research questions.
From online information searches and information provided by the researchers from respective countries, we produced an overview of the chronic obstructive pulmonary disease care in the four included countries. While national contexts are vastly different, there are some common barriers to effective care. For example, there appears to be a shared shortage of qualified medical professionals with expertise in chronic obstructive pulmonary disease management. Health systems focus excessively on specialised hospital care over primary care, which has implications for cost and geographic access. All countries included would likely benefit from focusing on preventing chronic obstructive pulmonary disease, through reducing smoking rates and improving air quality. We defined a series of research questions on these topics which were subsequently prioritised, planned and delivered successfully.
