Primary care provider interventions for addressing cancer screening participation with marginalised patients: a...

Cancer screening is an integral component of primary care, and providers can play a key role in facilitating screening. While much work has focused on patient interventions, there has been less attention on primary care provider (PCP) interventions. In addition, marginalised patients experience disparities in cancer screening which are likely to worsen if not addressed. The objective of this scoping review is to report on the range, extent and nature of PCP interventions that maximise cancer screening participation among marginalised patients. Our review will target cancers where there is strong evidence to support screening, including lung, cervical, breast and colorectal cancers.

This is a scoping review conducted in accordance with the framework by Levac et al. Comprehensive searches will be conducted by a health sciences librarian using Ovid MEDLINE, Ovid Embase, Scopus, CINAHL Complete and the Cochrane Central Register of Controlled Trials. We will include peer-reviewed English language literature published from 1 January 2000 to 31 March 2022 that describes PCP interventions to maximise cancer screening participation for breast, cervical, lung and colorectal cancers. Two independent reviewers will screen all articles and identify eligible studies for inclusion in two stages: title and abstract, then full text. A third reviewer will resolve any discrepancies. Charted data will be synthesised through a narrative synthesis using a piloted data extraction form informed by the Template for Intervention Description and Replication checklist.

Since this is a synthesis of digitally published literature, no ethics approval is needed for this work. We will target appropriate primary care or cancer screening journals and conference presentations to publish and disseminate the results of this scoping review. The results will also be used to inform an ongoing research study developing PCP interventions for addressing cancer screening with marginalised patients.
