is there an association between operator−patient sex, and outcomes in patients undergoing PCI? our work led by @ayayo_sharon and @TaxiarchiVicky using national @BCIS_uk data suggests that there may be. ➡️We included 138,112 consecutive PCI procedures in patients presenting with ACS in England and Wales, 2017−2020. ➡️ Male operators undertook the majority of PCI procedures; 130,604 (94.6%). ➡️Risk‐adjusted data found that, when treated by male operators, female patients experienced higher MACCE andmortality rates than male patients (4.1% vs. 3.7%; RR: 1.11 [95% CI: 1.05,1.18] and 3.1% vs. 2.7%; RR: 1.15 [95% CI: 1.08, 1.22]). ➡️Patient sex‐based differences in outcomes were not present for female operators ➡️ Operator−patient sex discordance was associated with lower transradial PCI (RR: 0.96 [95% CI: 0.95, 0.96]), lower prasugrel use (RR: 0.88 [95% CI: 0.82, 0.94]), higher MACCE (RR: 1.12 [95% CI: 1.06, 1.18]) and mortality (RR: 1.14 [95% CI: 1.07,1.21]) compared with operator−patient sex concordance. onlinelibrary.wiley.com/doi/… @drsonyaburgess @DrSarahjZaman @dataevan @propelresearch @mirvatalasnag
