Description
This measure shows the total number of days spent in hospital following an acute admission for a fall for people with fractured NOF. It replicates 'Fall with fractured NOF admissions' but shows bed-days (ie, the total amount of time spent in the hospital) instead of admissions. It is a proxy for the hospital resources that are used by different types of fall admissions. Improving the rehabilitation process inside a hospital can reduce the time spent in a hospital bed. Reducing the length of stay, as above, can help to maintain function and independence in older people. This indicator aligns closely with the system-level measure framework contributory measure for Acute Hospital Bed Days.
