Einführung in die qualitative Evidenzsynthese – Varianten und Anwendung

Zusammenfassung

Qualitative Evidenzsynthesen (QES) werden in der deutschen Rehabilitationsforschung bislang selten durchgeführt, obwohl robuste Synthesen qualitativer Evidenz zu wissenschaftlich fundierteren Entscheidungen im Gesundheitssystem führen können. Der Artikel führt in das Thema der qualitativen Evidenzsynthese ein, indem drei verschiedene Synthesemethoden – Thematische Synthese, Meta-Ethnografie und Grounded-Theory-Synthese – exemplarisch beschrieben und mit Beispielen aus der Rehabilitationsforschung illustriert werden. Es folgen Hinweise zur Auswahl geeigneter QES-Methoden und Überlegungen zu den Herausforderungen von QES, die mit der Literaturrecherche und Qualitätsbewertung der eingeschlossenen Studien verbunden sind. Auch werden Gütekriterien und Leitfäden für deren Anwendung vorgestellt. GRADE-CERQual kann zur Messung der Zuverlässigkeit der Ergebnisse aus QES angewendet werden. Der Artikel schließt mit Überlegungen zur Bedeutsamkeit der QES für die Rehabilitationsforschung.

Abstract

Qualitative evidence syntheses (QES) are still uncommon in German rehabilitation research, although robust syntheses of qualitative evidence may lead to more strongly scientifically based decisions in health care. This article introduces the topic of qualitative evidence synthesis by describing three different synthesis methods – thematic synthesis, meta-ethnography, and grounded theory synthesis – and illustrating them with examples from rehabilitation research. This is followed by guidance on selecting the appropriate QES-method and reflections on the challenges of QES that are associated with the literature search and quality assessment of the studies to be included in the synthesis. Likewise considerations on quality criteria and their application are taken into account. GRADE-CERQual provides guidance for assessing confidence of findings from QES. Finally the value of QES for rehabilitation research is discussed.
