Purpose: The purposes are to describe: 1) the background and theoretical basis for promoting self-care after lung transplant, 2) the rationale for proposing a technology-based intervention, 3) the rationale for partnering with multidisciplinary experts representing specific-knowledge domains, 4) the user-centered design principles employed to ensure consumer-centric design and functionality, and 5) the responsibilities and challenges of assembling and leading a multidisciplinary research team to design and test consumer-centric, technology-based interventions.
Theoretical Framework: Orem's theory of self-care purports that self-care agency, a person's ability to take responsibility for behaviors that maintain one's health, enhances performance of self-care behaviors and promotes healthy outcomes.
Methods (Design, Sample, Setting, Measures, Analysis): A one-group, iterative, design to develop and test a prototype of the hand-held intervention in controlled laboratory and field settings. Purposive sampling was used to recruit lung transplant recipients of both genders who demonstrated at least one or a combination of the following characteristics: blurred vision, tremors, and limited computer experience, in order to test and modify the interfaces (e.g., displays, interactivity) appropriately. Quantitative and qualitative data were collected to evaluate functionality (ergonomics, human computer interaction factors, and usability) in the controlled setting, and feasibility, utilization and satisfaction in the field setting. Data were analyzed for individual subjects and the sample in aggregate.
Results: The contributions of each discipline, the procedures used to design and test the hand-held technology, and the findings from the usability and functionality testing conducted in the controlled and field settings will be presented to demonstrate the development of a consumer centric, hand-held technology-based intervention to promote self-care after lung transplantation.
Conclusions and Implications: This research exemplar will serve as a guide for nurses interested in leading multidisciplinary research teams to develop consumer-centric, technology-based interventions.
