Identifying actions to foster cross-disciplinary global health research: a mixed-methods qualitative case study of the IMPALA programme on lung health and tuberculosis in Africa

Objectives To identify actions for fostering cross-disciplinary research (CDR) skills and collaborations in global health, and to produce recommendations for improving the design, implementation and management of cross-disciplinary global health research programmes. Design Using a North-South global health research programme as a case study-and following an adapted framework-we conducted qualitative research using document reviews, semi-structured interviews (purposive sampling) and participatory observation. We used baseline survey findings to identify potential interviewees and tailor interview guides. Setting Our case study was a 4.5-year (2017-2021) programme, namely, the International Multidisciplinary Programme to Address Lung Health and Tuberculosis in Africa (IMPALA). Led by a UK research institute, IMPALA spanned 22 partner organisations from 13 countries (10 in sub-Saharan Africa), and involved five research discipline groups: clinical science, social science, health systems, health economics and policy/research capacity. Participants Thirty-one IMPALA members were interviewed (July 2018-November 2019), with interviewees evenly split by gender (16 female and 15 male) and by Global North/South institution (15 non-African and 16 African). Twenty-five (81%) were researchers, comprising 18 senior researchers (professors, readers, associate professors and senior lecturers) and seven early career researchers (assistant professors, lecturers, research fellows, postdocs, research assistants and PhD students). Twenty-four programme events were observed (September 2018-April 2020) and 49 documents were reviewed (December 2017-April 2020). All 66 IMPALA staff were sent the baseline survey, receiving 51 responses (43/56 researchers and 8/10 non-researchers). Results Fourteen themes emerged, which suggested that CDR-while valued by many-is not universally understood, and the time it requires is often underestimated. We found that fostering CDR and managing tensions needs planning and continuous discussions and interactions. A shared vision with explicitly agreed goals and roles and active management of cross-disciplinary activities is essential. Conclusions Active planning, implementation and management of cross-disciplinary activities are essential for the success of cross-disciplinary global health research and should be separate from the primary research activities.

Automated summary

This study used a qualitative research approach to explore the challenges and strategies for fostering cross-disciplinary research in global health. The findings suggest that cross-disciplinary research is not universally understood and often underestimated in terms of time required. Effective planning, continuous discussions, and active management of cross-disciplinary activities are essential for successful cross-disciplinary global health research.
