Description
Summary:Summary Background & aims Dehydration of as little 2% of total body weight may impair physical and cognitive performance. The aim of this study was to investigate the prevalence of dehydration at the start and end of shifts in nurses and doctors on-call. The secondary aims were to assess the relation between hydration status and cognitive function. Methods This prospective cohort study was conducted on nurses and doctors working on medical and surgical admissions wards at a university teaching hospital. Participants arrived on the ward approximately 20 min before their shift and were asked to provide a urine sample. Height and weight were then measured. A 10 mL blood sample was analysed for full blood count, serum urea and electrolytes, and blood glucose. Cognitive function was assessed using a series of computer-based tests including the Stroop Colour Naming Interference Test and Sternberg Memory Paradigm. Participants then worked normally but were asked to keep a fluid diary for the duration of their shift and fluid balance was estimated. Tests were repeated at the end of the shift. Dehydration was defined as urine osmolality >800 mOsmol/kg and oliguria was defined as urine output
