Core tip: No surgery service in the world registers and/or audits the postoperative complications (PC) of all the surgical procedures it performs. Most economic studies of PC are of poor quality; without an accurate registration of PC, their costs cannot be reliably determined. The article describes ways of quantifying and classifying PC, discusses the perspectives from which their economic evaluation and monitoring can be approached, and makes recommendations. An accurate assessment of PC and their costs will allow us to determine which areas need investment in order to lower the incidence of PC, improve surgical results, and reduce economic costs.
