Aims and objectives. To explore older patients' participation during hospital admission and discharge. Background. Patient participation is suggested as a means to improve the quality of transitional healthcare. Older people with chronic diseases, physical disabilities and cognitive impairments often need to transfer from primary to hospital healthcare and vice versa. Design. This study adopts a participant observational research design. Methods. Participant observations of 41 older patients (over 75 years of age) during hospital admission and discharge were conducted in two hospitals in Norway (in 2012). The observations included short conversations with the patient and their next of kin to capture their participation experiences. Systematic text condensation was used to analyse the data material from the field notes.Results. Varying degrees of information exchange between healthcare professionals and patients, and a lack of involvement of the patient in decision-making (in admission and discharge) were observed and experienced by patients and their next of kin. The next of kin appeared to be important advocates for the patients in admission and provided practical support both during admission and discharge. Data suggest that patient participation in admission and discharge is influenced by time constraints and the heavy workloads of healthcare professionals. Patients' health conditions and preferences also influence participation. Conclusions. Several issues influence the participation of the older patients during hospital admission and discharge. Participation of the older patients needs continuous support from healthcare professionals that acknowledges both the individual patient's preferences and their capacity to participate. Relevance to clinical practice. Study findings report discrepancies in the involvement of older people and their next of kin. There is a need to increase and support older patients' participation in hospital admission and discharge.Key words: experiences, observational study, older patients, patient participation, patient perspective, transitional careWhat does this paper contribute to the wider global clinical community?Older patients' preferences and their capacity for participation in hospital admission and discharge varied considerably. This information must be taken into consideration to assist in informing healthcare workers about the appropriate level of patient participation.Heavy work load, crowded hospital wards, time pressure on healthcare professionals, ward routines constrain the participation of older patients during hospital admission and discharge.Increased awareness and competencies for healthcare professionals can be useful to improve patient participation during hospital admission and discharge.
