Abstract
Studies utilizing a systems perspective show that individual work system elements impact surgeon workload. However, limited work has shown how multiple elements together can affect perceived workload in the healthcare domain. Using NASA-Task Load Index (NASA-TLX), this study aimed to compare operating room workload across two work system factors (surgical specialty and case number of the day) using a large set of self-reported surgeon workload data. Thirty-two surgeons completed 545 workload surveys across a three month period. Surgeons reported significant differences in composite workload scores across the surgical specialties (F(7,544)=3.622, p=0.001). Significant interactions were identified between surgical specialty and case number for composite workload, F(20,534)=1.72, p=0.027. While such findings are promising, future work is needed across multiple institutions to establish baseline workload values across specialties with different patient characteristics and work systems.
