The co-author of a study that found 1,000 hospital patients were dying from 'avoidable' kidney problems has described the findings as "unacceptable".
"Good basic care would save these lives and save millions of pounds for the NHS," said Professor Donal O'Donoghue, consultant renal physician at Salford Royal NHS Foundation Trust.
Doctors and nurses need to make "elementary checks" to prevent [acute kidney injury], Dr O'Donoghue said.
"They also need to be aware that some common medications increase the risk of AKI."
A spokesman for NHS England said: "We have taken steps to ensure the NHS puts in place coherent long-term plans to reduce avoidable deaths in our hospitals, and to improve the way data is used in decision making."
