development of an integrated e health tool for people with or at high risk of cardiovascular disease the consumer navigation of electronic cardiovascular tools connect web application
International Journal of Medical Informatics, 2016Co-Authors: Lis Neubeck, Genevieve Coorey, David Peiris, John Mulley, Emma Heeley, Fred Hersch, Julie RedfernAbstract:Abstract Background Cardiovascular disease is the leading killer globally and secondary prevention substantially reduces risk. Uptake of, and adherence to, face-to-face preventive programs is often low. Alternative models of care are exploiting the prominence of technology in daily life to facilitate lifestyle behavior change. Objective To inform the development of a web-based application integrated with the primary care electronic health record, we undertook a collaborative user-centered design process to develop a consumer-focused e-health tool for cardiovascular disease risk reduction. Methods A four-phase iterative process involved ten multidisciplinary clinicians and academics (primary care physician, nurses and allied health professionals), two design consultants, one graphic designer, three software developers and fourteen proposed end-users. This 18-month process involved, (1) defining the target audience and needs, (2) pilot testing and refinement, (3) software development including validation and testing the algorithm, (4) user acceptance testing and beta testing. From this process, researchers were able to better understand end-user needs and preferences, thereby improving and enriching the increasingly detailed system designs and prototypes for a mobile responsive web application. Results We reviewed 14 relevant applications/websites and sixteen observational and interventional studies to derive a set of core components and ideal features for the system. These included the need for interactivity, visual appeal, credible health information, virtual rewards, and emotional and physical support. The features identified as essential were: (i) both mobile and web-enabled ‘apps', (ii) an emphasis on medication management, (iii) a strong psychosocial support component. Subsequent workshops ( n =6; 2×1.5h) informed the development of functionality and lo-fidelity sketches of application interfaces. These ideas were next tested in consumer focus groups ( n =9; 3×1.5h). Specifications for the application were refined from this feedback and a graphic designer iteratively developed the interface. Concurrently, the electronic health record was linked to the consumer portal. A written description of the final algorithms for all decisions and outputs was provided to software programmers. These algorithmic outputs to the app were first validated against those obtained from an independently programmed version in STATA 11. user acceptance testing ( n =5, 2×1.0h) and beta testing revealed technical bugs and interface concerns across commonly-used web browsers and smartphones. These were resolved and re-tested until functionality was optimized. Conclusion End-users of a cardiovascular disease prevention program have complex needs. A user-centered design approach aided the integration of these needs into the concept, specifications, development and refinement of a responsive web application for risk factor reduction and disease prevention.

Exploring the perceived usefulness and ease of use of a personalized web-based resource (care companion) to support informal caring: Qualitative descriptive study
'JMIR Publications Inc.', 2019Co-Authors: Turk A, Fairclough E, Grason Smith G, Lond B, Dale JAbstract:Background: Informal carers play an increasingly vital role in supporting the older population and the sustainability of health care systems. Care Companion is a theory-based and coproduced Web-based intervention to help support informal carers’ resilience. It aims to provide personalized access to information and resources that are responsive to individuals’ caring needs and responsibilities and thereby reduce the burdens associated with caregiving roles. Following the development of a prototype, it was necessary to undertake user acceptability testing to assess its suitability for wider implementation. Objective: This study aimed to undertake user acceptance testing to investigate the perceived usefulness and ease of use of Care Companion. The key objectives were to (1) explore how potential and actual users perceived its usefulness, (2) explore the barriers and facilitators to its uptake and use and (3) gather suggestions to inform plans for an area-wide implementation. Methods: We conducted user acceptance testing underpinned by principles of rapid appraisal using a qualitative descriptive approach. Focus groups, observations, and semistructured interviews were used in two phases of data collection. Participants were adult carers who were recruited through local support groups. Within the first phase, think-aloud interviews and observations were undertaken while the carers familiarized themselves with and navigated through the platform. In the second phase, focus group discussions were undertaken. Interested participants were then invited to trial Care Companion for up to 4 weeks and were followed up through semistructured telephone interviews exploring their experiences of using the platform. Thematic analysis was applied to the data, and a coding framework was developed iteratively with each phase of the study, informing subsequent phases of data collection and analysis. Results: Overall, Care Companion was perceived to be a useful tool to support caregiving activities. The key themes were related to its appearance and ease of use, the profile setup and log-in process, concerns related to the safety and confidentiality of personal information, potential barriers to use and uptake and suggestions for overcoming them, and suggestions for improving Care Companion. More specifically, these related to the need for personalized resources aimed specifically at the carers (instead of care recipients), the benefits of incorporating a Web-based journal, the importance of providing transparency about security and data usage, minimizing barriers to initial registration, offering demonstrations to support uptake by people with low technological literacy, and the need to develop a culturally sensitive approach. Conclusions: The findings identified ways of improving the ease of use and usefulness of Care Companion and demonstrated the importance of undertaking detailed user acceptance testing when developing an intervention for a diverse population, such as informal carers of older people. These findings have informed the further refinement of Care Companion and the strategy for its full implementation.

perspectives on patient reported outcomes content validity and qualitative research in a changing clinical trial environment
PharmacoEconomics, 2008Co-Authors: Nancy Kline Leidy, Margaret VernonAbstract:Patient-reported outcomes (PROs) represent the voice of the patient in drug and device evaluation. As such, the outcomes selected for evaluation must be relevant to the patient, and the instruments used to capture them must have sound measurement properties. This paper discusses the role of qualitative research methods in assuring PRO clarity and content validity in a clinical trial environment characterized by evolving regulatory policy, new advances in technology and increasingly diverse samples within global clinical trials. Three important PRO measurement issues influenced by these changes are addressed: (i) endpoint selection and instrument development; (ii) the adaptation of instruments for electronic administration; and (iii) conceptual equivalence of measures across diverse samples. These are viewed as interrelated issues of content validity that can be addressed through the appropriate and rigorous application of qualitative research methods. Focus groups, cognitive debriefing, user acceptance testing and translation methodologies are discussed as ways to address and document the content validity of PRO instruments and ensure the empirical data representing the voice of the patient is sound.
