Risk-adjusted surgeon performance was evaluated using mixed-effects logistic regression with observed-to-expected (O\/E) ratios. Positive deviants were defined as surgeons with O\/E ratios &lt;1.0 with 95% confidence intervals excluding unity. Surgical techniques were systematically reviewed through anonymized surveys, and volume-weighted analysis compared techniques of better and worse performers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0899823X26104814_as6\">\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Total sternal wound infection occurred in 175 patients (5.7%). Nine surgeons were stratified: better performers (O\/E &lt;1.0, n = 5), worse performers (O\/E \u22651.2, n = 3), and average performers (O\/E 1.0\u20131.19, n = 1). One surgeon achieved statistically significant superior performance (O\/E = 0.590, 95% CI: 0.39\u20130.91), representing 41% fewer infections than expected across 543 cases. Four protective techniques were identified: wound irrigation at closure (100% vs 0%), double skin preparation with chlorhexidine and povidone (100% vs 0%), superior Ioban adherence quality (5\/5 vs 3.7\/5 vs 3.2\/5,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001), and minimal cautery usage (1.0\/5 vs 3.2\/5 vs 3.5\/5,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0899823X26104814_as7\">\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Positive deviancy methodology successfully identified four modifiable surgical practices associated with reduced total sternal wound infections.
