title: Determinants of time to surgery for patients with hip fracture.
abstract: BACKGROUND
  Guidelines for hip fracture care suggest that patients with hip fracture should undergo surgery on the day of or day after admission to hospital. This study examined factors affecting time to surgery for hip fracture extracted from existing administrative datasets in New South Wales (NSW), Australia.
  
  
  METHODS
  A retrospective analysis of patients with hip fracture aged 65 years and over undergoing surgical intervention in NSW public hospitals between 1 July 2000 and 30 June 2011. A multinomial logistic model was used to identify factors impacting on time to surgery from 1 July 2006 to 30 June 2011.
  
  
  RESULTS
  A total of 49,317 hip fracture procedures were recorded during 2000-2001 to 2010-2011. Sixty-four per cent of patients received operative treatment on the day of or day after admission. Co-morbidity, type of surgical procedure and day of presentation all impacted significantly on time to surgery. Fourteen per cent required an inter-hospital transfer prior to receiving operative intervention. Transferred patients were 2.6 (95% confidence interval (CI): 2.31-2.85) times more likely to wait 2-4 days and 3.2 times more likely to wait 5 or more days (95% CI: 2.77-3.76) for surgery compared with patients presenting to an operating hospital.
  
  
  CONCLUSIONS
  Significant variation exists between hospitals in the time to surgery that is not solely explained by measures of case mix or geography. Opportunities exist to consider other factors contributing to this variation and to ensure timely access to surgical intervention in the future.
