Patients were excluded if they were younger than 18 years, lacked continuous insurance coverage for 1 year before and after the procedure, or underwent additional procedures on the surgery date of interest.

Explanatory variables included patient demographics, procedure type, and relevant comorbidities, which were used in multivariable logistic regression analysis.\u0000\u0000\u0000Results\u0000Of the 294 039 patients who met inclusion criteria (55.9% women and 44.1% men; mean [SD] age, 54.0 [18.6 years]), 45.2% filled prescriptions for postoperative antibiotics, including 55.3% of patients undergoing nasal procedures and 14.7% of patients undergoing oculoplastic procedures. Superficial surgical site infections occurred in 1.6% of patients, while deep surgical site infections occurred in 0.3% of patients. On multivariable logistic regression, patients receiving postoperative antibiotics were at significantly decreased risk of postoperative infections (nasal procedures: adjusted odds ratio [aOR], 0.144 [95% CI, 0.102-0.203]; oculoplastic procedures: aOR, 0.254 [95% CI, 0.104-0.622]) compared with those who did not receive postoperative antibiotics. Increased duration of postoperative antibiotics was not associated with reduced rates of infectious complications (nasal procedures: aOR, 1.000 [95% CI, 0.978-1.022]; oculoplastic procedures: aOR, 1.024 [95% CI, 0.959-01.092]).

When comparing complications between modified and conventional ECS, the relative risk for infections was 0.95 (95% CI, 0.34-2.7); for bleeding, 0; for nasal dorsal irregularities, 0.29 (95% CI, 0.16-0.53); for other cosmetic complications, 4.3 (95% CI, 0.87-21.1); for other functional complications, 0.47 (95% CI, 0.20-1.1); and for revision operations, 1.4 (95% CI, 0.83-2.3).\u0000\u0000\u0000Conclusions and Relevance\u0000Of the 31 studies included in this systematic review, less than half were of good methodology, and a significant level of heterogeneity was found regarding type of outcome measure used and reporting of complications.
