As the way we care for our ageing relatives becomes an increasingly hot topic, Dispatches goes undercover to investigate allegations of abuse and neglect at specialist dementia care homes run by Bupa, the UK's biggest name in healthcare. Bupa promises to provide person-centred, high quality care but covert footage captured in one home over three months by a Dispatches reporter raises serious questions about that commitment. Jackie Long investigates evidence of over-stretched and under-resourced care staff, questionable treatment of residents and safety worries. It's a picture that raises serious questions about how society should look after an ageing population and the quality of care provided by one of Britain's biggest brands.
