Atherosclerosis is an inflammatory disease. Because high plasma concentrations of cholesterol, in particular those of low-density lipoprotein (LDL) cholesterol, are one of the principal risk factors for atherosclerosis,1 the process of atherogenesis has been considered by many to consist largely of the accumulation of lipids within the artery wall; however, it is much more than that. Despite changes in lifestyle and the use of new pharmacologic approaches to lower plasma cholesterol concentrations,2,3 cardiovascular disease continues to be the principal cause of death in the United States, Europe, and much of Asia.4,5 In fact, the lesions of atherosclerosis represent . . .

QS242. IL-1β Exposure Leads to Gender-Dependent Differential Phosphorylation in the ERK Signaling Pathway in Rat Aortic Smooth Muscle Cells

BACKGROUND
In single-institution studies, overtriaging low-risk postoperative patients to ICUs has been associated with a low value of care; undertriaging high-risk postoperative patients to general wards has been associated with increased mortality and morbidity. This study tested the reproducibility of an automated postoperative triage classification system to generating an actionable, explainable decision support system.


STUDY DESIGN
This longitudinal cohort study included adults undergoing inpatient surgery at two university hospitals. Triage classifications were generated by an explainable deep learning model using preoperative and intraoperative electronic health record features. Nearest neighbor algorithms identified risk-matched controls. Primary outcomes were mortality, morbidity, and value of care (inverted risk-adjusted mortality/total direct costs).


RESULTS
Among 4,669 ICU admissions, 237 (5.1%) were overtriaged. Compared with 1,021 control ward admissions, overtriaged admissions had similar outcomes but higher costs ($15.9K [interquartile range $9.8K to $22.3K] vs $10.7K [$7.0K to $17.6K], p < 0.001) and lower value of care (0.2 [0.1 to 0.3] vs 1.5 [0.9 to 2.2], p < 0.001). Among 8,594 ward admissions, 1,029 (12.0%) were undertriaged. Compared with 2,498 control ICU admissions, undertriaged admissions had longer hospital length-of-stays (6.4 [3.4 to 12.4] vs 5.4 [2.6 to 10.4] days, p < 0.001); greater incidence of hospital mortality (1.7% vs 0.7%, p = 0.03), cardiac arrest (1.4% vs 0.5%, p = 0.04), and persistent acute kidney injury without renal recovery (5.2% vs 2.8%, p = 0.002); similar costs ($21.8K [$13.3K to $34.9K] vs $21.9K [$13.1K to $36.3K]); and lower value of care (0.8 [0.5 to 1.3] vs 1.2 [0.7 to 2.0], p < 0.001).


CONCLUSIONS
Overtriage was associated with low value of care; undertriage was associated with both low value of care and increased mortality and morbidity. The proposed framework for generating automated postoperative triage classifications is reproducible.

Case Series: Anatomic Popliteal Entrapment Syndrome Is Often a Difficult Diagnosis

INTRODUCTION: Female and male surgical residents may experience training differently, affecting the quality of learning and graduated autonomy. This study tests the null hypotheses that gendered words in verbal feedback and resident operative autonomy relative to performance are similar for female and male residents. METHODS: The Society for Improving Medical Professional Learning (SIMPL) application recorded 243,527 general surgery resident and attending evaluations of resident operative performance, resident autonomy, and case complexity for surgical procedures at 54 training programs from 2016-2021. Attendings provided verbal feedback for 2,683 cases; only cases that included dictated feedback were included in this study. Adjectives and gendered words in verbal dictations were quantified by natural language processing. Resident operative autonomy and performance levels, as evaluated by attendings, were reported on 5-point ordinal scales. Performance-adjusted autonomy was calculated as autonomy minus performance. RESULTS: Forty-four percent of cases were performed by female residents (N = 1,166). Gendered words were present in a greater proportion of dictations for female trainees (29%) compared with male trainees (25%, p = 0.04); this difference was attributable to male attendings disproportionately using male-associated words in dictations for female residents (28% vs 23%, p = 0.01). Overall, attendings perceived that male residents received greater performance-adjusted autonomy compared with female residents (p < 0.001) (Fig. 1). Similar patterns were observed when analyzing cases performed by female attendings (p = 0.06) and male attendings (p = 0.004) and when excluding high-complexity cases (all cases p = 0.004; female attendings p = 0.04, male attendings p = 0.03).Figure 1CONCLUSION: Gendered words in verbal feedback and performance-adjusted operative autonomy differed for female and male residents.
