Dramatic variations in patient death rates were revealed in the first-ever analysis of staffing and death rates over time, sparking calls for NHS England to investigate trusts where deaths have risen.
Study leader Professor Alison Leary told the Sunday Times that the data across 122 NHS trusts over four years showed “a very clear and consistent relationship between the absence of registered nurses available to patients and excess deaths.”
“Although organisations have tried to make up for the lack of registered nurses with other staffing groups, this has not improved survival,” added the chair of workforce modelling at London South Bank University and a senior consultant for the World Health Organisation.
