BACKGROUND: Quick Sequential Organ Failure Assessment (qSOFA) is recommended to identify sepsis. Odontogenic infection (OI) can progress to sepsis, causing systematic inflammatory complications or organ failure. PURPOSE: The purpose of the study was to measure the association/s between OI location and risk for sepsis at admission. STUDY DESIGN, SETTING, AND SAMPLE: This retrospective cohort study included subjects treated for OI at Baylor University Medical Center in Dallas, TX, from January 9, 2019 to July 30, 2022. Subjects > 18years old who were treated under general anesthesia were included. OI limited to periapical, vestibular, buccal, and/or canine spaces were excluded from the sample. PREDICTOR VARIABLE: The primary predictor variable was OI anatomic location (superficial or deep). Superficial OI infection includes submental, submandibular, sublingual, submasseteric, and/or superficial temporal spaces. Deep OI includes pterygomandibular, deep temporal, lateral pharyngeal, retropharyngeal, pretracheal, and/or prevertebral. MAIN OUTCOME VARIABLES: The primary outcome variable was risk for sepsis measured using a qSOFA score (0 to 3). A higher score (>0) indicates the patient has a high risk for sepsis. COVARIATES: Covariates were demographics, clinical, laboratory, and radiological findings, antibiotic route, postoperative endotracheal intubation, tracheostomy, intensive care unit, admission, and length of stay. ANALYSES: Descriptive and bivariate analyses were performed. A 2 test was used for categorical variables. The Mann-Whitney U test was used for continuous variables. Statistical significance was P<.05. RESULTS: The sample was composed of 168 subjects with a mean age of 42.821.5 and 69 (48.6%) subjects were male. There were 11 (6.5%) subjects with a qSOFA score > 0. The relative risk of a qSOFA > 0 for a deep OI is 5.4 times greater than for a superficial OI (136 (95.8) versus 21 (80.8%): RR (95% confidence interval): 5.4 (1.51 to 19.27), P=.004). After adjusting for age, sex, American Society of Anesthesiologists score, and involved anatomical spaces, there was a significant correlation between laterality and the number of involved anatomical spaces and qSOFA score (OR=9.13, 95% confidence interval: 2.48 to 33.55, adjusted P= <.001). CONCLUSION AND RELEVANCE: The study findings suggest that the OI location is associated with the qSOFA score >0.
