Nice's deputy chief executive, Professor Gillian Leng is expected to say that hospitals should not see Nice's new recommended 1:8 ratio as a limitation, but that not doing so would overload nurses and risk harming patients.
Leng will also tell hospitals that nurses need to be constantly on the alert for "red flag events", such as patients not receiving help to go to the bathroom or not receiving pain medication, which can trigger an immediate need for more nurses on the wards.
