Fall with other fracture bed-days

Description

This measure shows the total number of days spent in hospital following an acute admission for a fall for people with other fractures. It replicates 'Fall with other fracture 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.

Measure set

Falls and fractures

Improved recovery (hospital)

Notes about this measure set

Type of fall injury is based on the first event in the stay.
Other fracture: ICD-10 code S*2*, T02* and T12* and excluding fractured NOF in diagnosis codes 1–30

Calculating stays

Consecutive events that together make a stay are calculated with a similar methodology to the Manatū Hauora system-level measure Acute Hospital Bed Days.
Events are considered part of the same stay if:

the NHI was the same
the previous event had a transfer end type (DA, DF, DO, DP, DT, DW or ET)
the end date of the previous event was before or within 1 day of the next event
there was an external cause code of a fall (W00–W19) that occurred either on or before the event start date.

All sub-analyses are based on the information recorded in the first event in the stay. Sub-analysis is available using the following filters:

Te Whatu Ora district
ethnicity (Māori, Pacific, Asian and Other [including unknown]).

Numerator

The number of bed-days for all the events in acute and arranged admissions (stays) in hospital as the result of a fall for people with other fractures.
See notes for ICD codes and definitions.

Denominator

Resident population, Stats NZ population projections.

Denominator detail

Stays included in this measure are those that:

started with an acute or arranged event (admission type codes AA, AC, ZA or ZC)
started with an event that had an external cause code of a fall (W00–W19) that occurred either on or before the event start date.
started with an event with a non-NOF fracture diagnosis code (ICD-10 code S*2*, T02* and T12* and excluding codes S720* to S722*)

Denominator exclusions

Stays excluded from this measure are those that:

had an unknown age or gender
had an unknown health district, except when aggregated into the national total
consisted of only non-case-mix events (EXCLU purchase unit); non-case-mix events are otherwise included as long as a case-mix event is within the stay
started with a non-acute event code (ie, excluding falls that clearly occur in hospitals, like those measured in the Te Tāhū Hauora quality and safety markers).

Additionally, total bed-days excludes:

bed-days for residential care (health speciality code D10–19, D30-39, D50–59 or D70–79)
leave days.
