ABSTRACT

In thoracic surgery, disposable instruments are significant drivers of cost. There is variation in disposable instrument use among surgeons. It was hypothesized that a “passive awareness” intervention (displaying a pricing list of disposable instruments in the operating theater) would decrease operative costs. A current price list of disposable instruments used in thoracoscopic lobectomy was displayed in the thoracic surgery operating theater. Consecutive patients who underwent thoracoscopic lobectomy 6 months prior to price list display (Period 1) and 6 months following price list display (Period 2) were analyzed. Descriptive statistics were used to describe case distribution and lobectomy costs. T test and linear regression were used to examine the impact of surgeon, lobe removed, and time period. Over the study period, 71 patients underwent thoracoscopic lobectomy (Period 1: n = 36, Period 2: n = 35). Median per-lobectomy disposables cost decreased from $2063.22 (Interquartile range [IQR] $788.49) in Period 1 to $1885.92 (IQR $552.26) in Period 2; p = 0.03. There was a significant reduction in the median number of “high cost disposables” between Periods 1 and 2 (5.5-5.0, respectively; p = 0.04). In multiple linear regression, there was a decrease in total per-lobectomy cost of $286.21 (p = 0.03) and a decrease in stapler cartridge cost of $266.89 (p = 0.03) when controlling for surgeon and lobe. There was a significant reduction in disposable instrument expenditure per thoracoscopic lobectomy following posting of instrument costs in the operating theater. These findings suggest that a simple passive awareness intervention is effective in influencing surgeon behavior to reduce disposable instrument costs.
