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.
