Qualitative synthesis and systematic review in health professions education

Abstract

CONTEXT Formal qualitative synthesis is the process of pooling qualitative and mixedmethod research data, and then drawing conclusions regarding the collective meaning of the research. Qualitative synthesis is regularly used within systematic reviews in the health professions literature, although such use has been heavily debated in the general literature. This controversy arises in part from the inherent tensions found when generalisations are derived from in-depth studies that are heavily context-dependent. METHODSWe explore three representative qualitative synthesis methodologies: thematic analysis; meta-ethnography, and realist synthesis. These can be understood across two dimensions: integrative to interpretative, and idealist to realist. Three examples are used to illustrate the relative strengths and limitations of these approaches.DISCUSSION Against a backdrop of controversy and diverse methodologies, readers must take a critical stand when reading literature reviews that use qualitative synthesis to derive their findings. We argue that notions of qualitative rigour such as transparency and acknowledgment of the researchers' stance should be applied to qualitative synthesis.research methods

International clinical placements for Australian undergraduate nursing students: A systematic thematic synthesis of the literature

“…Due to the largely qualitative nature of the articles included in this review, which are drawn from data that is not intended to be generalizable and is not without bias, an approach was required that would take into account the interpretive nature of the studies (Bearman & Dawson, 2013). A key strength of thematic synthesis is its ability to allow for conclusions that are based on common elements or themes drawn from multiple divergent studies (Lucas, Baird, Arai, Law & Roberts, 2007).…”

The educational role of mobile instant messaging. Findings from a systematic review

“…In qualitative synthesis, study findings are systematically interpreted through a series of expert judgements to represent the meaning of the collected work, including qualitative studies -and sometimes mixed-methods and quantitative research (Bearman & Dawson, 2013). Thematic analysis involves repeated reading and analyzing of the studies and the identification of key themes and concepts related to the research questions.…”

Lean Applications: A Survey of Publications With Respect to South African Industry

“…Systematic literature review methodology is used to gather and analyse a vast amount of research studies and publications concerning a specific subject to answer predefined questions by integrating the empirical evidence from all relevant studies [57]. Multiple publications have been produced concerning the application of lean in manufacturing and service industries and this study seeks to gather and analyse publications focused on the application of lean manufacturing in South African Industry to understand trends in applications of lean manufacturing.…”
