A Mobile Phone App to Stimulate Daily Physical Activity in Patients with Chronic Obstructive Pulmonary Disease : Development, Feasibility, and Pilot Studies

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) demonstrate reduced levels of daily physical activity (DPA) compared to healthy controls. This results in a higher risk of hospital admission and shorter survival. Performing regular DPA reduces these risks. OBJECTIVE: To develop an eHealth intervention that will support patients with COPD to improve or maintain their DPA after pulmonary rehabilitation. METHODS: The design process consisted of literature research and the iterative developing and piloting phases of the Medical Research Council (MRC) model for complex clinical interventions and the involvement of end users. Participants were healthy adults and persons with COPD. RESULTS: The mobile phone interface met all the set requirements. Participants found that the app was stimulating and that reaching their DPA goals was rewarding. The mean (SD) scores on a 7-point scale for usability, ease of use, ease of learning, and contentment were 3.8 (1.8), 5.1 (1.1), 6.0 (1.6), and 4.8 (1.3), respectively. The mean (SD) correlation between the mobile phone and a validated accelerometer was 0.88 (0.12) in the final test. The idea of providing their health care professional with their DPA data caused no privacy issues in the participants. Battery life lasted for an entire day with the final version, and readability and comprehensibility of text and colors were favorable. CONCLUSIONS: By employing a user-centered design approach, a mobile phone was found to be an adequate and feasible interface for an eHealth intervention. The mobile phone and app are easy to learn and use by patients with COPD. In the final test, the accuracy of the DPA measurement was good. The final version of the eHealth intervention is presently being tested by our group for efficacy in a randomized controlled trial in COPD patients

Public involvement in designing a study on patient?witnessed cardiopulmonary resuscitation in hospital

The aim of this paper is to report the findings of the consultation rounds with former patients and health care professionals to inform the design of a qualitative study. We aimed to understand stakeholders' views regarding the relevance of a proposed study looking at the impact of patients witnessing cardiopulmonary resuscitation on other patients in hospital, the appropriateness of the proposed methodology and ethical aspects. We conducted an online survey (n = 22) and telephone interviews (n = 4) with former patients linked to the British Heart Foundation charity and a focus group (n = 15) with hospital health care professionals involved in cardiopulmonary resuscitation activities. Data were analysed using thematic analysis. The consultation rounds provided valuable advice on three major themes: conceptual aspects, methodological aspects and practical suggestions. The conceptual aspects were related to the relevance of the proposed study, the emotional impact for participating patients and how the social interaction among patients could influence the witnessing experience. Methodological advice included recruitment strategies and data collection methods such as the use of individual and focus group interviews, the timeframe of interviews with patients and the topics of the interview guides. In the third theme, practical suggestions were provided, such as strategies to advertise the study, improving the public's and participants' engagement throughout the study process and disseminating the findings. Overall, the study proposed in this consultation was considered relevant and worthy by patients and health care professionals to raise awareness and generate new evidence on an unconsidered aspect of cardiopulmonary resuscitation and of patients' hospital experience. These stakeholders' consultation rounds constituted a valuable exercise to design high-quality research based on a shared vision among researchers, service users and clinicians. They also provided pragmatic advice to inform critical care practice to support patients witnessing cardiopulmonary resuscitation in hospital

Case study: a bridge across the paradigms

Case study as a teaching and research tool has an extensive history in health and social sciences. Despite its suitability for many of the research questions that face nurses, nurses have not fully embraced case study as a comprehensive approach for research. The vagaries of the real-life clinical setting can confound methodologically purist researchers. Case study provides a milieu in which nurse researchers can respond to these vagaries and move towards a paradigmatic openness. In this paper, we argue that case study offers, as yet, under-explored and under-utilised potential as a bridge across the traditional research paradigms. We argue that case study has broad research application and epistemological, ontological and methodological flexibility. When used as a research approach, case study is both the process and end product of research. It provides a delineated boundary for inquiry, and a structural process within which any methods appropriate to investigating a research area can be applied
