While health research about persons of South Asian ancestry has been conducted for decades in Canada, it often uses pathologising approaches that fail to consider historical, social and political factors shaping health disparities. Further, this research rarely engages South Asian communities in meaningful ways, reinforcing feelings of disconnect and longstanding mistrust. Greater collaboration and transparency are needed to build trust and generate credible findings. The aims of this research protocol are to (1) examine how community engagement has been implemented in health research involving South Asian populations, (2) explore the experiences of both South Asian community members and academics involved in community-engaged research and (3) develop a framework guiding health research with and for South Asian communities in Canada, titled PRinciples to Operationalize Community Engagement, Equity, and Sustainability in South Asian Health Research in Canada (PROCESS).
This ongoing codesigned concurrent multimethods study is being conducted with community partners across Canadian provinces. First, the scoping review is examining how community engagement has been operationalised in health research involving South Asian populations in Canada. We are performing a search in Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, Web of Science, Scopus and PsycINFO databases for articles published between 2003 and 2024 referring to the concept of community engagement in South Asian health research. Two reviewers are independently completing abstract and full-text reviews based on preselected eligibility criteria. Data are being extracted from peer-reviewed studies using a data extraction framework. Findings will be aggregated and synthesised using descriptive content analyses. Second, a qualitative descriptive study is being conducted to explore the experiences of diverse stakeholders, including academics and community partners who are partaking in academic health research focused on South Asians. Semistructured interviews are being analysed using an inductive thematic content analysis. Results from the scoping review and qualitative interviews will be triangulated to detect emerging themes and patterns, which will enable the identification of principles to be incorporated within a draft of the PROCESS framework. In the final phase, we will use a modified Delphi process to iteratively codevelop the PROCESS framework with community partners and researchers across Canada.
The Faculty of Medicine and Health Sciences Institutional Review Board at McGill University approved the study’s protocol (24-05-080). Results will be submitted for publication in peer-reviewed journals and presented in academic and community forums. Results will also be shared with diverse audiences across Canada through multiple formats, including articles, conferences, infographics and social media, with the aim of raising awareness and promoting the adoption of research principles and practices for engaging South Asian communities in health research. This research received funding from the Canadian Institutes of Health Research (Grant #507768).

BackgroundFaster time to reperfusion can be achieved by minimizing various patient and system-level delays that contribute to total ischemic time. Procedural delays within the catheterization laboratory represent a non-negligible and modifiable component in the chain of reperfusion, but remain unquantified by conventional metrics such as door-to-ballon (D2B) time. Universal catheter approaches have rapidly gained traction as an alternative to the traditional two catheter approach for transradial coronary interventions. However, their utility for both diagnostic angiography and subsequent angioplasty is limited, and the impact of this strategy on reperfusion outcomes has remained unexplored. We utilized a procedural metric termed fluoroscopy-to-device (FluTD) time to quantify the efficiency of a single catheter strategy, and assessed its impact on epicardial and myocardial perfusion.
Methods and resultsIn this retrospective study, consecutive STEMI patients undergoing transradial primary PCI (pPCI) at a tertiary care center in India between May 2022 to October 2024 were analyzed. Patients were divided into two groups: 51 underwent PCI using a single universal guiding catheter (UGC), and 51 underwent the conventional two-catheter (CTC) approach. The primary outcome of the study was a comparison of the FluTD time between the two procedural strategies. Secondary outcomes included myocardial blush grade (MBG), Thrombolysis in Myocardial Infarction (TIMI) flow grade, total fluoroscopy time, radiation dose, device safety and efficacy, and procedural success.The median FluTD time was significantly shorter in the UGC compared to the CTC group (3 minutes [IQR 3–4] vs. 10 minutes [IQR 8–17], p Conclusion
A single catheter strategy for both angiography and pPCI in STEMI patients was associated with a significant reduction in FluTD time and improved microvascular perfusion, without compromising device safety or efficacy. In low- and middle-income countries (LMICs), where intra- and extra-procedural delays are often more pronounced, inclusion of the single catheter strategy can optimize catheterization workflows and yield substantial cost-savings.
