Cost and Quality: How Do Surgical Site Infection Bundles Measure Up?

ABSTRACT

Introduction: Enhanced recovery after operation and surgical site infection (SSI) bundles have been implemented in hospital systems nationwide to mitigate complications after colorectal operation. These quality improvement bundles (QIB) aim to improve patient safety and should decrease healthcare costs. This study identifies the impact of QIB on SSI rate and hospital costs. Method(s) Vizient and SSI reporting data was queried from 2016- 2021, for all colorectal resections tracked by the National Healthcare Safety Network across the enterprise. The operations were linked to a financial database. Data was analyzed quarterly to identify a relationship between SSI rate, hospital cost, and implementation of SSI mitigation elements. Result(s) 4,163 patients were identified during the study period. SSIs peaked in quarter 2 of 2018 at 5.3%, after which SSI mitigation efforts were announced. A steady decrease is seen in SSI rates, until quarter 3 of 2020, when our hospital system experienced its first COVID wave. With adjustment for procedure type, hospital costs increased by 15.8% per case from 2018-Q3 forward on average with the sharpest elevation observed in quarter 3 of 2019, due to medication startup costs for our SSI bundle. Conclusion(s) We successfully reduced colon SSIs with implementation of an ERAS bundle but incurred 16% greater costs compared with pre implementation, especially during the early implementation period.
