Professor Martin McKee of the London School of Hygiene & Tropical Medicine and co-author of the research paper, added: "This raises serious concerns about the quality of care provided in some care homes. When a care home has more than a few residents admitted to hospital with high sodium levels this may well be indicative of a systematic problem at the care home and the issue should be raised formally".
Co-author Professor David Stuckler, from the University of Oxford, said: "Clearly this level of dehydration is a problem. Further research is needed to understand why it is occurring. Are care home residents choosing to drink less than they should? Or, as has been speculated, are care home staff not offering enough water to reduce incontinence and the amount of assistance their residents require?"
