Evaluation of Outdoor swimming courses as an intervention to refresh and revitalise NHS workers

BackgroundFrontline healthcare staff working in the National Health Service (NHS) have been, and continue to be, under a significant level of work related stress as a result of the COVID-19 pandemic. Long hours and greater clinical need have impacted negatively on work-life balance. The results of our preliminary studies indicate that outdoor swimming may be an effective treatment for anxiety and depression. We therefore hypothesised that the activity could improve symptoms of work-related burnout and stress in NHS workers. The primary objective of this study was to gather feedback from NHS staff participating in supervised swimming sessions that took place in an outdoor pool in London and the sea in Cornwall on the value and effectiveness of this initiative as they perceived it. MethodsFollowing ethical approval (University of Portsmouth Science and Health research ethics committee SHFEC 2021-066), participants who had signed up to outdoor swimming courses provided by NHS Improvement in Cornwall and London were asked to give their consent to participate in an online survey. They were asked to complete them at three time-points: the week prior to, upon completion and six weeks after completion of the outdoor swimming course. As well as being asked for qualitative feedback, participants completed the Short Warwick-Edinburgh Mental Wellbeing Scale and the Copenhagen Burnout Inventory. Results85 (63.9%) of the 133 Participants who signed up to outdoor swimming courses completed the first survey, 62 (49.6%) the second and 43 (35.5%) the third. 41 (33.8%) completed all three surveys. Overall, there was a 14.8% increase in wellbeing scores when comparing the scores before and after the courses which was statistically significant (p<0.0001, d= 1.02). Compared to scores before the course, the scores at its conclusion were reduced by 25%, 18% and 18% in personal, work-related and client-related burnout respectively. These burnout scores were significantly different for personal (P<0.0001) and work-related burnout (P=0.0018). Qualitative feedback was overwhelmingly positive with the effects being broadly divided into those relating to mood and physical health, the social aspects of the group activity, feelings of achievement and self-care and mindfulness. ConclusionThis research suggests that the outdoor swimming activity, as a workplace intervention, can be an effective way of promoting staff wellbeing and reducing personal and work-related burnout. Further, formal trials of this intervention are justified.
