Description:Help on this term

Survival at 30 days post-admission for hip fracture surgery.

Rationale:Help on this term

Orthogeriatric care has been shown to reduce in hospital mortality (Kammerlander et al. 2010) and may also reduce 30-day mortality (Zeltzer et al. 2014).

Collection and usage attributes

Computation description:Help on this term

The numerator includes patients undergoing surgery for a hip fracture who were still alive at follow-up at 30 days. The 30 days should be calculated from the Episode of admitted patient care—admission date, DDMMYYYY for the hip fracture episode of care at the hospital at which the surgery for hip fracture was undertaken.

Both the numerator and the denominator include patients that were followed up at 30 days.

The denominator also includes patients who died in hospital during the episode at which the hip fracture surgery was undertaken (that is, Episode of admitted patient care—separation mode, code N = 8 Died).

Presented as a percentage.

Computation:Help on this term

(Numerator ÷ denominator) x 100

Numerator:Help on this term

Number of patients undergoing surgery for a hip fracture who were still alive at the 30 day follow-up.

Denominator:Help on this term

Number of patients undergoing surgery for a hip fracture in a period that is at least 30 days prior to the period for which survival is measured.

Comments:Help on this term

For hospitals collecting the Australian and New Zealand Hip Fracture Registry (ANZHFR) data set (ANZHFR Steering Group 2013), the variable Survival at 30 days post-surgery can be used for the numerator of this indicator. However, other hospitals will have to use linked mortality data at the state level to obtain information on patient deaths within the 30-day period.
