The Parker Model: applying a Qualitative Three-Step Approach to Optimally Utilize Input from Stakeholders When Introducing New Device Technologies in the Management of Chronic Rheumatic Diseases

Qualitative methods such as semi-structured interviews and focus-groups are used to evaluate the applicability and relevance of device technologies in clinical practice, but when used alone, often lack generalizability. This study aimed to assess the face validity and feasibility of using a composite, three-step qualitative method (the Parker Model), to inform the development and implementation of ava®, an electromechanical device (e-Device) for subcutaneous self-administration of the biologic, certolizumab pegol (CZP), used to treat rheumatic diseases.
