Clinical Trial Summary

The main purpose of this study is to assess and compare the hydration status of medical and nursing staff and to investigate the relationship between the hydration status, cognitive function and serum cortisol (marker of stress).

We hypothesise that a significant proportion of doctors and nurses will be dehydrated at the end of their working day. Some, as in other occupations, may be dehydrated at the start of their working day. This is likely to be associated with impairment in cognitive performance at the end of the working day compared to the beginning and expected to be more pronounced after a night shift. There may be less noticeable difference amongst nursing staff given the protected break time. Dehydration and associated impairment in cognition is of important clinical value as it can impact patient care. participants will be involved in the study for two shifts (one day and one night), aiming at 15 medical and 15 surgical nurses as well as 15 medical (total 15 day and 15 night shifts from each group) and surgical doctors (total 15 day and 15 night shifts from each group). Those that do not work both day and night shifts will participate for only one shift and a new participant will be recruited until target number of shifts is achieved.

Description:

End points

1. To assess the hydration status of hospital staff nurses and doctors oncall at work by measuring the following:

1. Urine and serum osmolality

2. Urine mass produced during the shift

3. Kidney function (U &Es)

4. Bioimpedance measures

2- To assess the effect of hydration on status of cognitive function and subjective feelings.

3- To assess the association between hydration status on stress hormone (cortisol) levels.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assess the prevalence of dehydration in nurses and doctors oncall.	Using urine osmolality as a marker of hydration we aim to assess the prevalence of dehydration in health care professionals before and after day and night shifts. Comparing nurses and doctors oncall, day and night as well diffrence between those working in medical and surgical admissions.	Participants will be followed up for the duration of their shift, approximately 12- 14 hours.	No
Secondary	Impact of hydration status on cognitive function	We aim to assess the impact of hydration on key executive cognitive before and after day and night shifts, comparing day and night using the following tests: Visual search; Stroop; Sternberg; Corsi	Participants will be followed up for the duration of their shift, approximately 12- 14 hours.	No
Secondary	The impact of hydration status on serum cortisol concentrations	The impact of hydration status on serum cortisol concentrations as a surrogate marker of stress will be assessed before and after day and night shifts. with day and night shifts assessed separately given the diurnal variations in cortisol.	Participants will be followed up for the duration of their shift, approximately 12- 14 hours.	No
