Background: Workplace culture impacts fundamentally on the provision of person-centred care. Taking a closer look at the workplace culture gives insight into and helps understanding how things are and how they are done in a particular setting. As workplace culture at the micro level directly influences the care provided, this is a vital step in transforming a culture towards person-centredness. Instruments support structuring this process and offer opportunities to include team members. Aim: Assessing the current workplace culture was the first aim of my PhD research on person-centred culture in a Swiss cancer outpatient clinic: A participatory inquiry. Methods: Data were collected through sequences of workplace observations using the Workplace Culture Critical Analysis Tool revised (WCCAT-r) (Wilson et al. 2020). In a second step, semi-structured conversational interviews taking up findings from the workplace observations completed the assessment of the current workplace culture. The observational data were analysed using a participatory creative hermeneutic approach involving the co-researchers (healthcare professionals and service users) enrolled in the PhD research. Analysis and findings from the conversational interviews are presented in a separate presentation. Findings: Two overarching themes - interpersonal relationships and competence - with four subthemes each, were found, describing person-centred aspects of the current culture. Conclusions: Workplace observations guided by the WCCAT-r offer insights in, and support describing the current workplace culture in terms of person-centredness. The experiences made by using the WCCAT-r are helpful for future use of the instrument in the same or different settings.
