Measure
Topical Antibiotic Ointment
The antibiotic arm received either erythromycin or a bacitracin containing ointment, depending on allergies, surgeon preference, and pharmacy availability. Patients were instructed to apply the ointment to the surgical incision(s) 4 times daily for 1 week.
Topical Non-Antibiotic Ointment
The non-antibiotic ointment arm received mineral oil/petrolatum-based artificial tear ointment with instructions to apply it to the surgical incision(s) 4 times daily for 1 week.

PRIMARY outcome

Timeframe: First Post-Operative Visit (~7-14 days)

The rate of superficial incisional or deep incisional surgical site infection (SSI) of clean and clean-contaminated wounds.

Measure
Topical Antibiotic Ointment
n=201 Participants
The antibiotic arm received either erythromycin or a bacitracin containing ointment, depending on allergies, surgeon preference, and pharmacy availability. Patients were instructed to apply the ointment to the surgical incision(s) 4 times daily for 1 week.
Topical Non-Antibiotic Ointment
n=187 Participants
The non-antibiotic ointment arm received mineral oil/petrolatum-based artificial tear ointment with instructions to apply it to the surgical incision(s) 4 times daily for 1 week.

SECONDARY outcome

Timeframe: First Post-Operative Visit (~7-14 days)

A secondary outcome is the rate of superficial or deep SSI in participants considered high risk for infection due to comorbidities such as smoking, exogenous immunosuppressive agent use, or medical conditions causing immunosuppression such as diabetes mellitus.

1/201 • Number of events 1 • Adverse events were collected until the final post-operative visit (approximately 3 months).
Among participants who did not proceed with surgery or who had no post-operative follow-up, adverse event data for events specific to the post-operative period (i.e. allergic contact dermatitis or wound dehiscence) were not collected. These participants were excluded from the denominator in determining frequency of these adverse events.
