Sheffield is among councils criticised for providing home care visits just 15 minutes long to elderly and disabled people.
Council care departments across the country have been attacked by charities for the practice, which has in some cases forced patients to choose between having a meal prepared or being helped to the toilet.
But Sheffield Council stressed that short calls are only for a small number of people requiring visits to make sure they are taking medication – and have not replaced longer visits for those who need them.
A spokesman said: “We are able to purchase 15 minute calls from contractors. However, each user will have gone through a full social work assessment to determine their level of need. Visits range from 15 minutes up to two hours.”
