A mum died hours after police put her to bed mistakenly believing she was drunk, an inquest heard.
Coroner Louise Slater urged police to teach officers about the condition Shirley Farmer was suffering before her death from pneumonia.
Medical expert Dr Melanie Levy said Mrs Farmer had a vitamin deficiency found in alcoholics, which impairs judgement.
The inquest heard 48-year-old Mrs Farmer- a recovered alcoholic, who had no alcohol in her system - dialled 999 reporting a break-in at her home in Thurnscoe. She ‘sounded intoxicated’ and made little sense, so officers put her to bed. A friend found her collapsed the next day.
A verdict of death by natural causes was recorded at the Sheffield inquest.
An internal investigation has been launched by South Yorkshire Police.
