Operationalising decolonisation in systematic reviews: can current tools help to mitigate for bias?
Katy Sutcliffe, EPPI Centre, University College London
Background: Decolonisation of research methods refers to the undoing of colonial ideologies within academic thinking and broadening critical and theoretical positions within methodological approaches to address power imbalances and inherent biases. Trust in systematic reviews is underpinned by transparency, rigour and objectivity at all stages of the review process. Frameworks such as GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) and GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) aim to improve transparency surrounding certainty or confidence in the evidence. A key element of these tools is to assess the overall directness or relevance of the synthesis findings, to examine whether they offer a ‘restricted’ answer to the review question because of the populations, interventions, comparators, or outcomes studied. Application of GRADE and CerQual could therefore be used to identify underrepresentation of important ethnic groups or marginalised populations in research.
Objectives: To explore how GRADE and GRADE-CERQual could be employed to support decolonisation of systematic reviews.
Methods: An exploration of how systematic reviews on issues known to disproportionately affect certain ethnic groups could use GRADE and CERQual to support interpretation of the evidence and decolonisation of research. We use case examples of reviews on conditions known to disproportionately affect people of African, African-Caribbean, and south-Asian descent, such as diabetes, to illustrate how reviewers might consider the directness of the evidence to those groups.
Conclusions: An exploration of how systematic reviews on issues known to disproportionately affect certain ethnic groups could use GRADE and CERQual to support interpretation of the evidence and decolonisation of research. We use case examples of reviews on health conditions known to disproportionately affect people of African, African-Caribbean, and south-Asian descent, such as diabetes, to illustrate how reviewers might consider the directness of the evidence to those groups.
Patient, public and/or healthcare consumer involvement: No specific patient or healthcare consumer involvement was sought for this abstract due to the theoretical nature of the work. However, the authors both value and advocate for diverse stakeholder involvement in the systematic review process.
