Background: Clinical supervision (CS) is a mechanism supporting clinical governance, quality assurance and staff development and wellbeing. There is abundance of publications about CS practised in psychological therapies and mental health services. In the UK, CS became a focus for nurses' practice development in the 1990s following recommendations in publications issued by government and professional nursing organizations. However, much of the research about CS in nursing focuses on trainee or auxiliary nurses. Our knowledge of CS for postqualification adult nursing is limited. No references were found about CS for nurses in stroke care. Aims: To contribute to knowledge about CS in stroke nursing care by exploring and understanding experiences and meanings of CS from the perspective of postqualification nurses in stroke care services. To contextualize understandings with data about workplace and organizational characteristics. Objectives: To form an understanding of the experiences and meanings of postqualification stroke care nurses about CS through a mixed methods approach, primarily through interviews. Methods: In-depth interviews were carried out to explore qualified nurses' experiences and meanings of CS in stroke care, analyzed using Interpretative Phenomenological Analysis (IPA). Site observations, questionnaires completed by stroke care nurses about characteristics of CS they received, and a pro forma completed by service leaders in interview sites about their service were used for contextual information. Findings: The study found provision of CS was inconsistent across stroke services. Staff nurses in acute stroke units rarely received CS, and when they did, it was usually part of performance related measures. Four superordinate themes were identified through Interpretative Phenomenological Analysis: Psychological impact, Reflection as personal growth, Relational factors, and Participants' meanings of CS.
