Introduction: A recent study suggested that sex discordance between surgeons and patients negatively affects the outcomes of patients undergoing common surgical procedures.
Aim: We sought to assess whether such an impact exists for periprocedural outcomes of percutaneous coronary intervention (PCI).
Material and methods: From 2014 to 2020, data on 581,744 patients undergoing single-stage coronary angiography and PCI from 154 centers were collected. Patients were divided into four groups based on the patient and operator sex. Operator-patient sex discordance was defined as the procedure done by a male operator on a female patient or by a female operator on a male patient.
Results: Of 581,744 patients treated by 34 female and 782 male operators, 194,691 patients were sex discordant with their operator (female operator with male patient 12,479; male operator with female patient 182,212) while 387,053 were sex concordant (female operator with female patient 6,068; male operator with male patient 380,985). Among female patients, no difference in the risk of periprocedural complications, including death (0.65% vs. 0.82%; p = 0.10), between patients discordant versus concordant with operators was observed. Among male patients the risk of death (0.55% vs. 0.43%; p = 0.037) and bleeding at the puncture site (0.13% vs. 0.08%; p = 0.046) was higher in patients discordant with operators. However, the differences were no longer significant after adjustment for covariates.
Conclusions: No detrimental effect of operator-patient sex discordance on periprocedural outcomes was confirmed in all-comer patients undergoing PCI. Some of the observed differences in outcomes were primarily related to the differences in baseline risk profile.
