Integration in mixed-methods studies: existing practices, considerations and recommendations for pharmacy research

Mixed methods research is increasingly used to investigate complex issues in health and healthcare. Purposeful integration of the qualitative and quantitative strands has a significant potential to yield insights that exceed the value of a study's constituent qualitative and quantitative components alone. The philosophical foundations of mixed methods in pragmatism support the importance of integration as a focus of designing and conducting mixed methods research. Integration can be facilitated by considering and employing study components such as distinct mixed methods research questions, sampling strategies, data transformations, joint data displays and integrated narrative discussions. This manuscript explores the importance of integration in mixed-methods research, provides examples of these techniques used in pharmacy research and offers practical recommendations for implementing these techniques.
