Abstract

Update 

This article was updated on August 24, 2011, because of a previous error. In Figure 1, the labels that had previously read "Alive at 1 year" now read "Deceased at 1 year," and vice versa.

Background: 

A recent systematic review has indicated that mortality within the first year after hip fracture repair increases significantly if the time from hospital admission to surgery exceeds forty-eight hours. Further investigation has shown that avoidable, systems-based factors contribute substantially to delay in surgery. In this study, an economic evaluation was conducted to determine the cost-effectiveness of a hypothetical scenario in which resources are allocated to expedite surgery so that it is performed within forty-eight hours after admission.

Methods: 

We created a decision tree to tabulate incremental cost and quality-adjusted life years in order to evaluate the cost-effectiveness of two potential strategies. Several factors, including personnel cost, patient volume, percentage of patients receiving surgical treatment within forty-eight hours, and mortality associated with delayed surgery, were considered. One strategy focused solely on expediting preoperative evaluation by employing personnel to conduct the necessary diagnostic tests and a hospitalist physician to conduct the medical evaluation outside of regular hours. The second strategy added an on-call team (nurse, surgical technologist, and anesthesiologist) to staff an operating room outside of regular hours.

Results: 

The evaluation-focused strategy was cost-effective, with an incremental cost-effectiveness ratio of $2318 per quality-adjusted life year, and became cost-saving (a dominant therapeutic approach) if ≥93% of patients underwent expedited surgery, the hourly cost of retaining a diagnostic technologist on call was <$20.80, or <15% of the hospitalist's salary was funded by the strategy. The second strategy, which added an on-call surgical team, was also cost-effective, with an incremental cost-effectiveness ratio of $43,153 per quality-adjusted life year. Sensitivity analysis revealed that this strategy remained cost-effective if the odds ratio of one-year mortality associated with delayed surgery was >1.28, ≥88% of patients underwent early surgery, or ≥339.9 patients with a hip fracture were treated annually.

Conclusions: 

The results of our study suggest that systems-based solutions to minimize operative delay, such as a dedicated on-call support team, can be cost-effective. Additionally, an evaluation-focused intervention can be cost-saving, depending on its success rate and associated personnel cost.
