RESUMEN
BACKGROUND: Because of revisions to insurance reimbursement costs, medical fees have changed for investigations and percutaneous coronary intervention (PCI) treatment of chronic coronary syndrome (CCS). In this retrospective study, we investigated these changes and their effects on mortality and cardiovascular events.MethodsâandâResults: We included 1,483 patients who underwent elective PCI for CCS between April 2010 and September 2019. The primary outcomes were changes in PCI procedure fees and all included hospitalization fees due to the biennial revisions of reimbursement costs across 5 time periods (~2 years each). Secondary outcomes were rates of survival and freedom from major adverse cerebral and cardiovascular events (MACCE) in each time period. Patient characteristics were generally unchanged over the study period; however, treatment procedures changed significantly, with changes in the approach site (from transfemoral to transradial access; P<0.0001) and final device (from bare-metal stents to drug-eluting stents; P<0.0001), and an increase in the use of imaging modalities (P<0.0001). Medical fee parameters (primary outcomes) decreased significantly from 2010 to 2019 (P<0.001): PCI procedure fees decreased by 25%, whereas all included hospitalization fees decreased by 20%. There were no significant differences in survival or freedom-from-MACCE rates between periods. CONCLUSIONS: Because of revisions to reimbursement prices, there were rapid and significant decreases in PCI procedure and hospitalization fees for CCS. These changes had no effect on mortality or cardiovascular events.
