Delay to theatre after hip fracture is common in order to medically optimise the patient prior to surgery. The association between delay to surgery and mortality after hip fracture remains a contentious issue.

We aimed to investigate how medical postponement, time to surgery and correction of medical abnormalities prior to surgery affect peri-operative mortality after hip fracture.

From February to December 2007 prospective data was collected from all acute trauma units in Scotland relating to hip fracture patients' fitness for theatre, reasons for postponement of surgery and subsequent plans of action. The data-set recorded whether medical abnormalities were identified following criteria reported by McLaughlin et al. Survival at 30-days post-operation was used as primary outcome measure. Multivariable logistic regression models were used to control for differences in case-mix between patients.

Data were available for 4284 patients. Patients postponed for medical reasons were less likely to survive to 30 days compared to patients who were not postponed (87% (122/947) versus 93% (3098/3337)). Survival also decreased as time to theatre increased - 92% of patients operated on during the same/next day vs. 89% of those operated on admission day four. However, after controlling for differences in case-mix variables and co-morbidities, neither variable significantly affected survival. We then analysed whether delaying surgery to resolve medical problems improved survival. Adjusted survival was not significantly different between those patients who had their medical problem resolved prior to surgery compared to those patients who were not postponed. Individuals who were postponed but did not have their clinical abnormality resolved prior to surgery had significantly lower adjusted 30 day survival.

The possible benefits of postponement need to be weighed against prolonged discomfort and the possibility of developing other complications. Postponing patients who cannot be medically improved should be avoided.

We have investigated how medical postponement, the time to surgery and the correction of medical abnormalities, according to McLaughlin criteria, before operation affected peri-operative mortality after fracture of the hip. From February to December 2007, in addition to core data, the Scottish Hip Fracture Audit collected information relating to surgical delay. Data were available for 4284 patients which allowed 30-day survival analysis to be performed. Multivariable logistic regression models were used to control for differences in case-mix.

Patients with major clinical abnormalities were more likely to have a postponement and had a lower unadjusted 30-day survival. The time to operation and postponement were not associated with higher mortality after adjustment for case-mix. Correction of major clinical abnormalities before surgery improved the adjusted survival, but this improvement was not significant (p = 0.10). Postponement without correction of a medical abnormality before surgery was associated with a significantly lower (p = 0.006) 30-day adjusted survival. The possible benefits of postponement need to be weighed against prolonged discomfort for the patient and the possibility of the development of other complications.
