Abstract

Background

A key avoidable expense in the surgical setting is the wastage of disposable surgical items, which are discarded after cases even if they go unused. A major contributor to wastage of these items is the inaccuracy of surgeon preference cards, which are rarely examined or updated. The authors report the application of a novel technique called cost heatmapping to facilitate standardization of preference cards for microvascular breast reconstruction.

Methods

Preference card data were obtained for all surgeons performing microvascular breast reconstruction at the authors' institution. These data were visualized using the heatmap.2 function in the gplot package for R. The resulting cost heatmaps were shown to all surgeons performing microvascular breast reconstruction at our institution; each surgeon was asked to classify the items on the heatmap as “always needed,” “sometimes needed,” or “never needed.” This feedback was used to generate a lean standardized preference card for all surgeons. This card was validated by all surgeons performing the case and by nursing leadership familiar with the supply needs of microvascular breast reconstruction before implementation. Cost savings associated with implementation were calculated.

Results

Implementation of the preference card changes will lead to an estimated per annum savings of $17,981.20 and a per annum reduction in individual items listed on preference cards of 1,693 items.

Conclusion

Cost heatmapping is a powerful tool for increasing surgeon awareness of cost and for facilitating comparison and standardization of surgeon preference cards.
