Abstract

Background: 

An investigation was conducted to establish the hospital-wide prevalence of cast saw injuries and to identify variables that put patients at increased risk, with the goal of reducing the injury rate.

Methods: 

Information was collected from January 2010 through December 2012 on all patients who had a cast removed or cut at our institution. Locations included the operating suites, emergency department, ambulatory clinics, and hospital floors. A cast cutting log was used to capture the total number of casts cut. An adverse event form was used to document each injury. A continuous quality improvement approach was used throughout the study period to implement incremental improvements to our program. Changes included an education and certification program on cast saw use for all providers, a protocol for a plastic surgery consultation, and a cast saw blade inspection protocol with maintenance logs.

Results: 

Twenty-nine injuries occurred in 23,615 cast cuttings over the three years, for an overall rate of 1.23 (95% confidence interval [CI], 0.86 to 1.76) per 1000. A minor decrease in cast saw injuries was recorded over the course of the study (eleven of 8043 [1.37 per 1000] in 2010, ten of 7885 [1.27 per 1000] in 2011, and eight of 7687 [1.04 per 1000] in 2012), but the decrease was not significant (p = 0.87). The emergency department had the highest rate of cast saw injuries (p < 0.0001), with a significantly greater rate during the night compared with the day (eleven of 1293 [8.51 per 1000] compared with fifteen of 19,419 [0.77 per 1000], respectively; p < 0.0001). The injuries were all minor. Key risk factors for a cast saw injury included provider inexperience, patient sedation, and poor cast saw blade condition.

Conclusions: 

The rate of cast saw injuries in a busy pediatric orthopaedic department was small, but a considerably increased risk existed for those patients cared for in the emergency department by orthopaedic residents. Improving education and training in cast saw use has the potential to decrease the prevalence of cast saw injuries over time.
