Developing a research question: A research primer for low- and middle-income countries

Abstract

As demand for emergency care (EC) systems in low- and middle-income countries (LMICs) grows, there is an urgent need to expand the evidence base for clinical and systems interventions in resource limited EC settings. Clinicians are well placed to identify, define and address unanswered research questions using both quantitative and qualitative approaches. This paper summarises established research priorities for global EC and provides a step-wise approach to developing a research question. Research priorities for global EC broadly fall into two categories: systems-based research and research with a clinical care focus. Systems research is integral to understanding the essential components of safe and effective EC delivery, while clinical research aims to answer questions related to particular disease states, presentations or population groups. Developing a specific research question requires an enquiring, questioning and critical approach to EC delivery. In quantitative research, use of the PECO formula (Population, Exposure, Comparator, Outcome) can help frame a research question. Qualitative research, which aims to understand, explore and examine, often requires application of a theoretical framework. Writing a brief purpose statement can be a helpful tool to clarify the objectives of a qualitative study. This paper includes lists of tips, pitfalls and resources to assist EC clinical researchers in developing research questions. Application of these tools and frameworks will assist EC clinicians in resource limited settings to perform impactful research and improve outcomes for patients with acute illness and injury.

Research Question, Objectives, and Endpoints in Clinical and Oncological Research: A Comprehensive Review

“…Given the evolution and the increasing requirement for emergency care, clinical researchers are advised to adopt a population, exposure, comparator, outcome (PECO)/population, exposure, comparator, outcome (PICO) approach to construct the study objectives and carry out quantitative research. In contrast, qualitative research which is carried out to understand, explore, and examine requires the researcher to understand what and why the research is undertaken along with the roles of the researcher, research process/steps, and participants [7,8].…”
