Implementing, adapting, and validating an evidence-based algorithm for hip fracture surgery.

OBJECTIVES

Reoperations are common after surgical treatment of hip fractures but may be reduced by optimal choice of implant based on fracture classification. We hypothesized that implementing a surgical treatment algorithm was possible in our hospital and would result in a reduced reoperation rate.

DESIGN

Retrospective comparative study.

SETTING

Provincial level III trauma center.

PATIENTS

The evidence-based "Hvidovre Algorithm" for treatment of hip fractures was adopted and implemented at our provincial institution in September 2008. Three hundred eighty-six consecutive patients older than 50 years admitted with a hip fracture in the first year after implementation were prospectively included and compared with 417 retrospectively included similar patients admitted within the last year before implementation.

INTERVENTION

Implementation of an evidence-based treatment algorithm for hip fracture surgery.

RESULTS

Eighty-five percent (330 of 386) patients were operated according to the algorithm after implementation, compared with 67% (280 of 417) of procedures before implementation (P < 0.001). After implementation, the overall reoperation rate showed a tendency toward a reduction to 8% (32 of 386) from 12% (48 of 417) (P = 0.1). Among all the 803 included patients, the reoperation rate was lower if procedures had been performed according to the algorithm recommendations: 9% (53 of 610) versus 14% (27 of 193) (P = 0.009).

CONCLUSIONS

The algorithm for hip fracture surgery was easily implemented, and our results support that using it facilitates a low reoperation rate. The reoperation rate may be further reduced with higher adherence to algorithm recommendation.
