Although previous studies have suggested that higher volumes of colectomies performed by surgeons and hospitals are associated with lower mortality, less is known about the relationship between volume and resource utilization. The research team tested the association between volume, costs, complications, length of stay, and mortality using data from the National Inpatient Sample. Results suggest higher volumes for both surgeons and hospitals were associated with lower costs, fewer complications, shorter length of stay, and lower mortality. Propensity score matching showed no significant difference in mortality by surgeon volume (7.38% vs 7.46%, P =.0.842), but significantly fewer complications (45.06% vs 49.10%, P =.008), shorter length of stay (11.8 vs 13.1 days, P <.0001), and lower costs ($33 142 vs $29 578, P <.0001) for high-volume surgeons. Although the major driver of complications and mortality is burden of disease and comorbid conditions, individual surgeon volume is an important determinant of length of stay and costs.
