BackgroundInfectious diseases consult (IDC) and antimicrobial stewardship (AMS) intervention independently demonstrate improved management of Staphylococcus aureus bacteremia (SAB). However, data supporting utilizing both strategies is limited. The objective of the current study is to assess evidence-based bundle adherence for SAB in the presence and absence of mandatory IDC and AMS pharmacist review in a multi-site health system.MethodsThis retrospective study included adult inpatients with SAB from January 2016 to December 2018 at seven hospitals. Outcomes were compared between three groups: pre-mandatory IDC and AMS review (group 1), post-mandatory IDC and pre-AMS review (group 2), and post-mandatory IDC and AMS review (group 3). The primary outcome was bundle adherence defined as: appropriate intravenous antimicrobial therapy, appropriate duration of therapy, 24–48-hour surveillance cultures until documented clearance, echocardiography, and removal of indwelling intravenous catheters, if applicable. Secondary endpoints included individual bundle components, source control, length of stay (LOS), 30-day bacteremia-related readmission, and in-hospital all-cause mortality.ResultsA total of 579 patients met the final inclusion criteria for analysis. Complete bundle adherence was achieved in 65% of patients for group 1 (n = 371), 54% for group 2 (n = 87), and 76% for group 3 (n = 121). Adherence to bundle elements was significantly higher in group 3 when compared with group 1 (odds ratio [OR] 0.58, 95% confidence interval [CI] 0.37–0.93), and group 2 (OR 0.37, 95% CI 0.20 – 0.67). No difference in bundle adherence was noted between groups 1 and 2. When comparing groups 1, 2 and 3, significant differences were seen in obtaining echocardiography (91% vs. 83% vs. 100%; P = 0.0378), and hospital LOS (10.5 vs. 8.85 vs. 12.0 days; P = 0.0149), respectively. Increased hospital LOS in group 3 may be due to nonsignificant higher rates of complicated bacteremia compared with groups 2 and 1 (32% vs. 44% vs. 43%, P = 0.09), respectively. No differences were noted for readmission or mortality.ConclusionThe addition of AMS pharmacist review to mandatory IDC significantly improved quality care bundle adherence.DisclosuresAll authors: No reported disclosures.

273 Background: Vascular involvement is a key determinant of resectability and treatment sequencing in pancreatic cancer (PC). Current staging requires multidetector CT (MDCT) and endoscopic ultrasonography (EUS), but there are still occasions when vascular involvement cannot be fully assessed. Current NCCN guidelines recommend using magnetic resonance imaging (MRI) for clarifying these ambiguities. The primary aim of our study is to access the accuracy of CT, MRI, and EUS in staging resectabilty of PC. The secondary aim is to assess internal consistency in the evaluation of vascular involvement among different staging modalities. Methods: We retrospectively reviewed 40 medical records of patients who were treated at LUMC for PC from 2006 to present. We evaluated 8 MDCT scans and 8 MRI scans in addition to their EUS reports. Seven board certified radiologists analyzed the 16 imaging studies using a standardized template. Unweighted Kappa statistic and observed agreement analysis was calculated to assess inter-observer agreement on vessel involvement between the imaging studies compared to the EUS reports. We sought to examine degree of concordance for involvement of the superior mesenteric artery (SMA), superior mesenteric vein (SMV), and main portal vein (MPV) with the pancreatic tumor. Results: Low Kappa and observed agreement in respect to vascular involvement between MDCT and EUS was found for SMV (K = 0.33, 62.5%), SMA (K = -0.2, 62.5%), and MPV (K = 0.38, 75%), indicating low concordance. Low Kappa and observed agreement in respect to vascular involvement between MRI and EUS was found for SMV (K = 0.09, 37.5%), SMA (K = 0.14, 62.5%), and MPV (K = 0.47, 75%). Low Kappa and observed agreement in respect to vascular involvement between MRI and MDCT in comparison to EUS was found for SMV (K = 0.11, 50%), SMA (K = 0.20, 75%), and MPV (K = 0.14, 62.5%). Conclusions: Concordance was shown within each imaging modality when analyzed by radiologists. Due to high discordance across different staging modalities, however, MRI and CT scans complement each other in determining degree of vascular involvement. We believe both imaging modalities should be used in staging borderline resectable PC.

This investigation explored the factor structure, reliability, and validity of the Devereux Elementary School Behavior Rating Scale, employing a large (n = 648) sample of children. Factor analysis suggested that the Devereux scale can be described by four factors, which were named Disruptive-Oppositional, Poor Comprehension-Disattention, Cooperative-Initiating, and Performance Anxiety. All four factors showed high internal consistency, and three of the four were stable over a 17-mo. period. Correlations of the four factors with academic achievement, IQ, socioeconomic status, and peer ratings of social competence are presented. All four factors showed significant relations with these variables, with Poor Comprehension-Disattention the strongest of all. Multiple regression analysis indicated that the Poor Comprehension-Disattention factor accounted for significant variance in academic achievement even after IQ was taken into account. Large differences between classroom means on the factor scores suggested that Devereux ratings for individual students may need to be interpreted cautiously.
