Applying mixed methods research to a cost-benefit analysis

Purpose: This paper applies mixed methods research to analyse the costs and benefits of conducting sponsored clinical drug trials in a publicly funded New Zealand hospital. Design: The research design incorporates mixed methodology and mixed methods. The costs and benefits of clinical drug trials are quantified using data from a retrospective case-control study. Qualitative focus groups, interviews and semi-structured surveys are used to explore the costs and benefits as perceived by stakeholders. Findings: Our mixed methods research design enables the analysis of three layers; societal, organisational and personal. Each of these layers reveals different perspectives on sponsored clinical drug trials and the related costs and benefits within a New Zealand public hospital. Value: This paper provides guidance for investigators seeking ways to use both quantitative and qualitative methods to enhance their understanding of research problems.
