BackgroundDespite positive results from several international Enhanced Recovery After Surgery (ERAS) protocols, the United States has been slow to adopt ERAS protocols, in part due to concern regarding the expenses of such a program. We sought to evaluate the potential annual net cost savings of implementing a US-based ERAS program.Study DesignUsing data from existing publications and experience with an ERAS program, a model of net financial costs was developed for surgical groups of escalating numbers of annual cases. Our example scenario provided a financial analysis of the implementation of an ERAS program at a United States academic institution based on data from the ERAS Program for Colorectal Surgery at The Johns Hopkins Hospital.ResultsBased on available data from the United States, ERAS programs lead to reductions in lengths of hospital stay that range from 0.7 to 2.7 days and substantial direct cost savings. Using example data from a quaternary hospital, the considerable cost of $552,783 associated with implementation of an ERAS program was offset by even greater savings in the first year of nearly $948,500, yielding a net savings of $395,717. Sensitivity analysis across several caseload and direct cost scenarios yielded similar savings in 20 of the 27 projections.ConclusionsEnhanced Recovery After Surgery protocols have repeatedly led to reduction in length of hospital stay and improved surgical outcomes. A financial model, based on published data and experience, projects that investment in an ERAS program can also lead to net financial savings for US hospitals.Copyright © 2016 American College of Surgeons.
