Brief Summary:

Dehydration is recognised as a major issue in healthcare. Recovery after illness, extended length of stay, pressure sores and slow tissue recovery can all be impacted by dehydration. One of the biggest problems for many people with regard to getting a drink is easy, independent access - if they can't reach the jug/cup without a struggle then they often will go thirsty and potentially become dehydrated.

The purpose of this study is to investigate the impact of dehydration on outcome in patients 65 years and over. Furthermore we aim to assess the impact of providing easy, 24 hour, independently accessible fluids on reducing dehydration as well as improving patient experience.

We hypothesise that patients who are dehydration will take longer to recover from illness and stay in hospital for longer periods.

Group/Cohort Intervention/treatment
Patients aged 65 years and over
All patients aged 65 years and over admitted to acutely to medical wards
Device: The Hydrant
The Hydrant is a new form of "drinking system" that may be used to provide continuous access to hydration will be given to 20 patients. 10 of the patients will have mild cognitive impairment with Mini Mental State Examination less than 24 and 10 with normal cognitive function. Patients and staff will be interviewed to assess the feasibility of the hydrant.

Primary Outcome Measures :
  1. Serum Osmolality [ Time Frame: At admission and 48hrs post admission to hospital ]

Biospecimen Retention:   Samples With DNA
Participants provide 5mls of whole blood on admission, at 48 hours post admission and at 3 month following discharge. This blood is to be analysed for urea, creatinine, sodium, potassium, osmolality, full blood count as well as renin and aldosterone.
