ABSTRACT

INTRODUCTION: Surgical site infections are common postoperative complications. Some operating rooms have open-floor drainage systems for fluid disposal during endourologic cases, although nonendoscopy cases are not always allowed in these rooms. We hypothesized that operating rooms with open-floor drainage systems would not materially affect risk of surgical site infections for patients undergoing open and laparoscopic procedures. METHODS: Patients who had surgical site infections from 2016 through 2020 were identified from data of the National Surgical Quality Improvement Program. Patients without surgical incisions, with open wounds, and with surgical site infections at surgery were excluded. The primary outcome was surgical site infection occurrence within 30 days of surgery. Multilevel multivariable logistic regression was used to estimate the observed-to-expected surgical site infection ratio for each operating room (2 with and 23 without open-floor drainage systems). RESULTS: We identified 8,419 surgical cases, of which 802 (9.5%) were performed in operating rooms with open-floor drainage systems; 166 patients (2.0%) had surgical site infections. Of the surgical site infections, 7 (4.2%) occurred in operating rooms with open-floor drainage systems. Surgical specialty, American Society of Anesthesiologists physical status, higher case acuity, dyspnea, immunosuppression, longer surgical duration, and wound classification were associated with surgical site infections (P < .05 for all). The observed-to-expected ratios of surgical site infections occurring in the 2 operating rooms with open-floor drainage systems were 0.85 and 1.15. The odds ratio of surgical site infections for urologic cases performed in room with vs without open-floor drainage systems was 1.30 (P = .65). CONCLUSIONS: Urology operating room designs often include open-floor drainage systems for water-based cases. These drainage systems were not associated with an increased risk of surgical site infections.

ABSTRACT

BACKGROUND: Relationships among sugars and dental caries in contemporary societies are unclear. The authors describe young children's intakes of nonmilk extrinsic (NME) and intrinsic/milk sugars and relate those intakes to dental caries. METHODS: The authors conducted cross-sectional analyses of dietary data collected from the Iowa Fluoride Study using three-day diaries for subjects at ages 1, 2, 3, 4 and 5 years and for subjects aged 1 through 5 years according to dental caries experience at 4.5 to 6.9 years of age. They categorized foods and beverages as containing NME or intrinsic/milk sugars. RESULTS: Subjects' total, NME, food NME and intrinsic/milk sugars intakes at ages studied did not differ between subjects with and without caries experience. Beverage NME sugars intakes at age 3 years predicted caries (P < .05) in logistic regression models adjusted for age at dental examination and for fluoride intake. CONCLUSIONS: Dental caries is a complex, multifactorial disease process dependent on the presence of oral bacteria, a fermentable carbohydrate substrate and host enamel. A simple NME-intrinsic/milk sugars categorization appears insufficient to capture the complex dietary component of the caries process. CLINICAL IMPLICATIONS: Cariogenicity is more likely a function of the food and/or beverage vehicle delivering the sugar and the nature of exposure-that is, frequency and length of eating events-than of the sugar's categorization.
