Weill Cornell Medicine-Qatar (WCM-Q) is strengthening expertise in evidence-based medicine by promoting the critical analysis and synthesis of scientific research through initiatives led by its Institute for Population Health (IPH).
According to IPH officials, the strongest scientific evidence comes from systematically analysing and synthesising all relevant studies rather than relying on individual research alone.
Systematic reviews and meta-analyses provide robust evidence that underpins evidence-based healthcare, supporting safe, effective and patient- and community-centred care.
Dr Sohaila Cheema, associate professor of clinical population health sciences and assistant dean of IPH, said: “Systematic reviews play an important role in helping health professionals identify, select, appraise and synthesise primary study data extracted from published literature in an unbiased way to answer a specific research question. This produces reliable scientific evidence essential to ensuring evidence-based healthcare practice and patient-centred care.”
As part of these efforts, IPH recently organised a regional workshop, ‘Introduction to Systematic Review and Meta-analysis: Principles and Practice’, which attracted more than 35 participants from across the region. The programme was designed for physicians, dentists, nurses, pharmacists, allied health practitioners, researchers, educators and healthcare administrators seeking to strengthen their understanding of evidence-based healthcare.
Dr Cheema noted that the level of interest received in the workshop from participants within Qatar and across the region is very encouraging.
The workshop introduced participants to the principles of evidence-based medicine and the methods used to conduct and interpret systematic reviews and meta-analyses. It also provided practical guidance on designing and conducting systematic reviews. Participants explored key concepts including primary and secondary research, systematic reviews, meta-analyses and the step-by-step process of conducting systematic reviews.
The programme also covered formulating research questions using the PICO/PICOTS framework, literature searching and screening, data extraction, and assessing study quality and risk of bias. The PICO/PICOTS framework is a structured approach used to formulate clear, answerable research questions and establish eligibility criteria for systematic reviews and clinical trials.
The workshop also examined methods for synthesising and reporting systematic reviews, highlighting the differences between qualitative and quantitative synthesis and providing an overview of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. These internationally recognised reporting standards promote transparent and comprehensive reporting of systematic reviews and meta-analyses.
Additional sessions focused on the critical appraisal of systematic reviews with and without meta-analysis, principles of meta-analysis and meta-regression, and approaches to evaluating the strength of evidence. Participants also gained practical experience in appraising published systematic reviews and developing review protocols.
The workshop featured presentations by Dr Karima Chaabna, assistant professor of clinical population health sciences and manager of population health research at IPH; Dr Amit Abraham, assistant professor of clinical population health sciences and assistant director of IPH; Dr Sonia Chaabane, epidemiologist, senior specialist in population health research at IPH and instructor in population health sciences; and Anupama Jithesh, research projects coordinator at IPH.
IPH, a dedicated institute within WCM-Q, was created to advance education, research, community, and related matters. It aims to advance public health and community wellness through education, evidence-based health research and lifestyle medicine initiatives aimed at addressing chronic diseases such as diabetes and obesity across the region.
