ABSTRACT
BACKGROUND:
Conflicting evidence exists regarding the utility of prophylactic postoperative antibiotics in tissue expander (TE)-based breast reconstruction. This study evaluated the risk of surgical-site infection between patients receiving 24 hours of perioperative antibiotics alone versus prolonged postoperative antibiotics within a propensity score-matched cohort.METHODS:
Patients undergoing TE-based breast reconstruction receiving 24 hours of perioperative antibiotics alone were propensity score-matched 13 to patients receiving postoperative antibiotics based on demographics, comorbidities, and treatment factors. Incidence of surgical-site infection was compared based on duration of antibiotic prophylaxis.RESULTS:
Of a total of 431 patients undergoing TE-based breast reconstruction, postoperative antibiotics were prescribed in 77.2%. Within this cohort, 348 were included for propensity matching (no antibiotics, 87 patients; antibiotics, 261 patients). After propensity score matching, there was no significant difference in incidence of infection requiring intravenous (no antibiotics, 6.9%; antibiotics, 4.6%; P = 0.35) or oral antibiotics (no antibiotics, 11.5%; antibiotics, 16.1%; P = 0.16). In addition, rates of unplanned reoperation ( P = 0.88) and 30-day readmission ( P = 0.19) were similar. After multivariate adjustment, prescription of postoperative antibiotics was not associated with a reduction in surgical-site infection (OR, 0.5; 95% CI, -0.3 to 1.3; P = 0.23).CONCLUSIONS:
Within a propensity score-matched cohort accounting for patient comorbidities and receipt of adjuvant therapies, prescription of postoperative antibiotics after TE-based breast reconstruction conferred no improvement in rates of TE infection, reoperation, or unplanned health care use. These data underscore the need for multicenter randomized trials on the utility of antibiotic prophylaxis in TE-based breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.
