Description of intervention(s) / exposure
This is a retrospective observational study in patients over the age of 70 who underwent hip fracture surgery between July 2011 and July 2015 at a Victorian Metropolitan Hospital.
This pilot study, with a view to developing into a larger scale study, is designed to find out whether some peri-operative variables are independent risk factors, being increased risk of death, greater hospital costs or both.
In summary, perioperative variables, mortality rates and associated hospital costs will be evaluated over the period from July 2011 to July 2016.

Statistical methods / analysis
A pilot study (n = 62) was conducted, which assisted the calculation of sample size and established the feasibility of data collection.
The mortality fractions and the 95% confidence levels will be determined first. In order to examine the association between testing variables and mortality, a survival analysis will be used to estimate the hazard ratios (or similar measures of association) taking into account the time until death and censoring.
