Abstract
Background: We have a gap in current methodologies to present evidence in meaningful context. While use of systematic reviews by different stakeholders to inform healthcare decisions is improving, other documents such as practice guidelines and media reports may influence demands for access to, or funding of new healthcare technologies. Objectives: We describe a new methodology to contextualize the quality of patient-centered outcomes evidence represented by related documents including reviews, practice guidelines, editorials, and media reports. Methods: The systematic bibliometric review focuses on 2 key concepts: (1) Informed by systematic review methodology quality of evidence for patient-centred outcomes using cumulative meta-analysis and the GRADE approach and (2) Informed by bibliometric methodology Quantity of original research, related documents, and citation relationships between original research and related documents (e.g., reviews, practice guidelines, editorials, media reports). It includes 4 steps: (1) research questions and document selection; (2) data extraction and analysis; (3) document network relationships; (4) document network visualization (Figure). Results: The primary output from the systematic bibliometric review is a 1-page figure juxtaposing (1) the evidence the annual cumulative meta-analysis estimate of effect and quality of evidence by patient-centered outcomes (GRADE) against (2) the context the network of relationships between related documents and original research. Conclusions: The systematic bibliometric review aims to help decision-makers conceptualize, interpret, and visualize the quantity, quality, and relevance of original research data within a network of related documents. Applications of this methodology include support for clinical and policy decisions, and identification of research gaps. Further research is needed to understand the utility and acceptability of this methodology by evidence consumers.
