In Evidence-based Family Practice, requesting a diagnostic test should be based on two issues. First is whether the test is accurate and thus will significantly help in clinical decision making. Second is whether the test is appropriate and acceptable for the patient. This involves careful discussion of risks and benefits based on the physician’s knowledge and experience and the patient’s values and preferences.

Systematic reviews and meta-analysis combine results and analysis of data from different primary studies (e.g. cross-sectional studies, case-control studies, cohort studies) conducted on similar or related research topics. They are secondary studies that guide clinical decision-making, delivery of care and policy development. This article aims to discuss how to conduct a systematic review and meta-analysis. The steps in conducting a systematic review and meta-analysis include: 1) Identify the purpose including formulating the research question and validating the purpose of the literature scan, 2) Formulate the objectives, 3) Literature search including selection of studies based on population, intervention, comparison and outcome, 4) Retrieval of full text articles, 5) Critical appraisal of articles, 6) Data extraction, 7) Data analysis and 8) Writing the final report. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is a useful guide in conducting and write systematic review and meta-analysis. While ethics approval is not usually required for systematic review and meta-analysis, authors of such study should still observe good practices including avoiding plagiarism, maintaining transparency and ensuring data accuracy.

Qualitative research is a type of research that provides deeper insights into real-world problems. It gathers participants’ experiences, perceptions, and behaviours and answers the how’s and whys instead of how many or how much. It could be structured as a stand-alone study, purely relying on qualitative data or it could be part of mixed-methods research that combines qualitative and quantitative data. Some of the most common methodologies being used in qualitative research include ethnography, grounded theory, phenomenological study, narrative study, historical study and case studies. This article aimed to discuss how to conduct a qualitative study. The steps in conducting a qualitative study include: 1) Create a purpose statement; 2) Formulate the Research Questions; 3) Perform a Literature Review; 4) Choose a qualitative research methodology to use; 5) Identify and Select the Study Population; 6) Develop the data collection procedure; 7) Collect the data and 8) Analyze the data, which if using thematic analysis, can include writing the final report. In writing and appraising qualitative studies, the Consolidated Criteria for Reporting Qualitative Studies (COREQ) can serve as a useful guide. Lastly, like in quantitative studies, researchers doing qualitative studies should be aware of the ethical issues involved in their work, anticipate possible ethical concerns, craft protection strategies, and make the necessary referrals to research ethics committees, appropriate organizations, and other agencies if the need arises.
