Transition to shift work: Sleep patterns, activity levels and physiological health of early-career paramedics
Introduction: The physiological impact of transitioning from full-time study to work in occupations that involve high-stress environments and shift work may plausibly impact sleep patterns and quality. There are limited studies focusing on the transition to shift work in graduate paramedics.
Objective: This study aimed to assess early metabolic markers of health, activity and sleep quality during the first 5 months of rostered shift work in a cohort of 28 graduate paramedics. Method: Participants were tested for 4-week blocks before starting shift work (baseline), and during their 1st and 5th month of shift work. In each block, sleep and activity levels were monitored on workdays and non-working days using a wrist-worn actigraph. Health and wellbeing assessments were also conducted at regular intervals across the study protocol. Results: The number of sleep episodes, overall sleep quantity and self-reporting of poor sleep quality increased during shift work, however sleep efficiency did not differ significantly. All sleep metrics recorded during non-work days were not different to baseline with exception of the night before returning to work, for which reduced sleep duration was recorded. Sedentary behaviour increased across the study, attributable to a decline in light exercise. No significant changes occurred in vigorous physical activity, average steps recorded per day, fasting blood glucose levels, systolic and diastolic blood pressure or participants’ weight, however waist circumference did increase significantly.
Conclusion: Results of this study may indicate that early risk factors for major medical conditions are presenting in the first six months of ambulance work, warranting further large-scale and longitudinal studies to gauge implications for paramedic health. The alterations to sleep patterns observed for paramedics commencing their employment may merit a range of changes, including training around sleep habits, health advice and a review of rostering and shift practices. |

Research Interests: During my extensive experience as a paramedic working rotational shift work, I feel that shift work has altered my sleep patterns. I have identified a gap in the literature regarding the effects of shift work on graduate paramedics. My area of interest is how this impacts the health of the paramedic in the acute phase and potentially as a chronic condition. My broader research interests are centred on investigating the effects of shift work on new recruits, a field that has historically lacked innovative research. Along with a colleague, I was awarded a Teaching Development Grant for $6000 to undertake a project titled "The quality of sleep in final year Paramedicine students". This grant evolved into a major research interest for me. My Masters research project, completed in 2020, was the first quantifiable investigation of sleep and health of graduate paramedics from anywhere in the world. My continued passion for research saw me commence a PhD study in semester 1 of 2021. This project is focused on improving undergraduate paramedicine education by providing avenues for students to adopt a challenge appraisal of high acuity simulations. This contemporary project will be supervised by highly experienced experts in the fields of psychology and curriculum development. |
