Is there a weekend effect in hip fracture patients presenting to a United Kingdom teaching hospital?

Figure 2 American Society of Anesthesiologist grade of patients admitted with hip fracture had a significant effect on 30-d mortality (P < 0. 001), 120-d mortality (P < 0.001) and time to surgery (P = 0.001). As ASA increased, the mortality rate at 30- and 120-d increased, whilst the percentage of patients undergoing surgery within 36 h decreased. Percentages are expressed as means. All P-values derived from logistic regression model. ASA: American Society of Anesthesiologist.
