[Utilization and reporting of qualitative research methods in health services research in Germany: A scoping review on original research publications (2010-2019)]

Abstract

Background: Qualitative research methods offer a unique perspective on health care services. However, little is known about the actual application of qualitative methods in health services research. Therefore, the aim of this study was to gain an overview of volume and variety of the use of qualitative research methods in health services research in Germany.

Methods: By means of a scoping review, a systematic literature search of the database PubMed was conducted in September 2020. We included (1) qualitative studies in (2) a health services setting (3) in Germany, (4) published in either German or English as (5) original research in a journal (6) between 2010 and 2019. After removing duplicates, tandem teams of researchers first performed a title and abstract screening, followed by a full text screening. Data was extracted by using a category grid considering research focus, study design and reporting.

Results: In total, 759 articles were included in the title and abstract screening. After applying the exclusion criteria, 97 articles were included in the data extraction. The studies investigating mainly subjective perspectives of different stakeholders, especially physicians and patients, covered 13 areas of health care. Interviews were the dominant form of data collection (n=64). Data analysis was mainly conducted using content analysis (n=65).

Conclusion: A clear absolute increase in publications since the mid-2010s can be observed. At the same time, there has been a strong tendency towards certain methods being used for data collection and analysis. Compared to reporting standards and guidelines (e.g., COREQ), incomplete reporting of research methods has been noted. The results show that both an extension of the range of methods and the quality of reporting need to be discussed.
