The UK's Global Health Respiratory Network: Improving respiratory health of the world's poorest through research collaborations.

Respiratory disorders are responsible for considerable morbidity, health care utilisation, societal costs and approximately one in five deaths worldwide [1-4]. Yet, despite this substantial health and societal burden – which particularly affects the world’s poorest populations and as such is a major contributor to global health inequalities – respiratory disorders have historically not received the policy priority they warrant. For example, despite causing an estimated 1000 deaths per day, less than half of the world’s countries collect data on asthma prevalence (http://www.globalasthmareport.org/). This is true for both communicable and non-communicable respiratory disorders, many of which are either amenable to treatment or preventable.

Part of the reason for this has been competing donor priorities leading to a focus on other conditions such as HIV, with a relative neglect of non-communicable lung diseases and of environmental determinants of lung disease. We hope that the launch of the UK’s Global Health Respiratory Network (GHRN; ) represents a change in approach, at least in the UK. Central to the strength of this Network is bringing together experts across the full range of respiratory health disciplines, including social, health, clinical and biomedical sciences as well as laboratory-based, clinical, implementation and health systems research, in non-communicable respiratory disorders (eg, asthma, chronic obstructive pulmonary disease [COPD]), communicable respiratory diseases (eg, tuberculosis [TB], pneumonia), and lung health (public health) to work collaboratively and synergistically, rather than competitively. It also brings those working in public health, primary care, secondary care (paediatrics and adult) and palliative care together, looking at respiratory diseases through a system-wide scope to – most importantly – lead to improvements in the respiratory health of the world’s poorest people.

Following the 2015 decision of the UK Government to channel £1.5 billion of the Official Development Assistance (ODA) budget through UK Research and Innovation (UKRI)[5], there was an open call for proposals from the UK’s National Institute for Health Research (NIHR) to establish Global Health Research Groups and Units [https://www.nihr.ac.uk/explore-nihr/funding-programmes/global-health/]. Groups would represent new partnerships between UK and low- and middle-income country (LMIC) partners, and Units would be for existing UK-LMIC partnerships to scale-up their work. Both have strong, equitable north-south partnerships that focus on addressing the needs of the poorest populations in hitherto neglected disease areas. In response to this NIHR initiative, and a related Global Challenges Research Fund (GCRF) programme from UKRI, a number of proposals with a focus on, or including, respiratory health were successful, as summarised in .

This has created a cohort of UK-funded Southern-facing research collaborations with a shared focus not only on respiratory related illness, but on capacity building and multidisciplinary research in active partnership with LMIC researchers. In recognition of the opportunity to move towards a more collaborative model of working, a number of the funded programmes addressing respiratory diseases came together with a view to sharing experiences, knowledge, lessons learnt and networks; leading to the formation of the GHRN. The core aim of the GHRN is to work collaboratively to improve global respiratory health, focusing on the poorest populations of the world. To this end, GHRN members, with funders’ approval, agreed to pool resources to create a secretariat.

The UK arm of the GHRN has met both virtually and in-person to share ideas and establish initial priorities for work over the short- to medium-term. This initial list of priorities is summarised in . More fundamentally, we have sought to develop respectful, trusting relationships between the scientific and management leadership teams of these various initiatives that enable collaborative sharing and learning. Examples have included supporting ethics and regulatory approvals for overseas studies where a suitable infrastructure does not exist in an institution, sharing experiences in relation to good financial grant practice, and identifying additional networks through which pathways to impact can be accelerated and amplified.

Whilst it is still early days for the GHRN, we are pleased to see that our collaborative approach has been welcomed by our funders and, as such, other Units and Groups are being recommended to consider this approach. We hope that this will lead to researchers in other disease areas following suit to seek out synergies that can accelerate collaborative global working in their respective fields.

Although encouraged by the opportunities for working together, there are of course challenges. For example, within the limited resources available, we are grappling with how best to ensure that researchers based in LMICs are able to lead and shape this collaboration. Building on the equitable partnerships developed and nurtured as part of these initiatives, we are looking into the practicalities of using web-based platforms to facilitate real-time engagement across our Network; this is not straightforward as we have yet to identify a platform that works across all countries and there are also logistical and financial challenges of organising simultaneous interpreting facilities across multiple languages. However, we are confident that by working together we can greatly increase our ability to overcome these challenges.

Looking ahead, we see tremendous opportunities from joined-up working. Ours is most definitely an open model of collaboration that will, we hope, see the GHRN grow in the coming years. We aspire, with continuing support beyond the initial 2017-21 first term for these collaborations, for our Network to develop an online knowledge hub on respiratory diseases and a growing cohort of GHRN-fellows/GHRN-scholars. We encourage those interested in working with us, whether in the UK or internationally, to join our Network to improve the respiratory health of the world’s poorest populations.
