Incidence of SSI was compared between patients who received AP 0-30 versus 31-60 min of incision.

This study investigated the association of the pandemic with SSI occurrence after cardiac surgeries. <b><i>Patients and Methods:</i></b> From 2014 to 2022, patients undergoing cardiac surgery were included and categorized into pre-pandemic and during-pandemic groups. Surgical site infections were classified into harvest-site, superficial sternal, and complex sternal infection. Multiple logistic regression and inverse probability weighting assessed the association of the pandemic with SSI. <b><i>Results:</i></b> Among a total of 26,143 patients, 793 SSIs occurred. The during-pandemic patients were younger (61.87 ± 10.58 vs. 65.64 ± 11.82) with a higher male proportion (70.1% vs. 67.4%) and a higher prevalence of all studied comorbidities/risk factors (expect cigarette smoking). Total SSI rate decreased substantially from 3.3% before COVID-19 to 1.8% afterward (p < 0.001). Inverse probability weights analyses evinced an independent association of the pandemic with a reduced risk of total (adjusted odds ratio [OR]; 0.59; 95% confidence interval [CI], 0.45-0.78), harvest-site (adjusted OR, 0.36; 95% CI, 0.19-0.70), and superficial sternal infection (adjusted OR, 0.60; 95% CI, 0.43-0.81). No significant association was observed with complex sternal site infection (adjusted OR, 1.05; 95% CI, 0.55-2.01).

Our purpose was to determine the difference in suction tip bacterial contamination rates between suction-positive and suction-negative tips. <b><i>Materials and Methods:</i></b> A matched-pair analysis of the contamination of surgical suction tips over a six-hour period was performed in two clean operating rooms. One suction tip was connected to standard wall suction (suction-positive group), with a matched control tip not connected to wall suction (suction-negative group). At time zero and then at hourly intervals for six hours, the distal 3 cm of suction tips were removed, placed in nutrient broth for 48 hours, then plate cultured.

From our data, operating room staff should have an awareness that suction tips represent a potential source of bacterial concentration.

This study aimed to identify the rate of positive (+)CLABSI in trauma patients and risk factors associated with (+)CLABSI. <b><i>Methods:</i></b> The 2017-2021 Trauma Quality Improvement Program database was queried for trauma patients aged ≥18 years undergoing central-line placement. We compared patients with (+)CLABSI vs. (-)CLABSI patients. Bivariate and multivariable logistic regression analyses were performed. <b><i>Results:</i></b> From 175,538 patients undergoing central-line placement, 469 (<0.1%) developed CLABSI.
