Introduction: Patients with tIPH (used here to refer to traumatic intraparenchymal hemorrhagic contusion) or intraparenchymal hemorrhage face high rates of mortality and persistent functional deficits. Prior studies have found an association between blood pressure variability (BPV) and neurologic outcomes in patients with spontaneous IPH. Our study investigated the association between BPV and discharge destination (a proxy for functional outcome) in patients with tIPH. Methods: We retrospectively reviewed the charts of patients admitted to a Level I trauma center for ≥ 24 hours with tIPH. We examined variability in hourly BP measurements over the first 24 hours of hospitalization. Our outcome of interest was discharge destination (home vs facility). We performed 1:1 propensity score matching and multivariate regressions to identify demographic and clinical factors predictive of discharge home. Results: We included 354 patients; 91 were discharged home and 263 to a location other than home. The mean age was 56 (SD 21), 260 (73%) were male, 22 (6%) were on anticoagulation, and 54 (15%) on antiplatelet therapy. Our propensity-matched cohorts included 76 patients who were discharged home and 76 who were discharged to a location other than home. One measure of BPV (successive variation in systolic BP) was identified as an independent predictor of discharge location in our propensity-matched cohorts (odds ratio 0.89, 95% confidence interval 0.8-0.98; P = 0.02). Our model demonstrated good goodness of fit (P-value for Hosmer-Lemeshow test = 0.88) and very good discriminatory capability (AUROC = 0.81). High Glasgow Coma Scale score at 24 hours and treatment with fresh frozen plasma were also associated with discharge home. Conclusion: Our study suggests that increased BPV is associated with lower rates of discharge home after initial hospitalization among patients with tIPH. Additional research is needed to evaluate the impact of BP control on patient outcomes.

Blood pressure variability (BPV) has been shown to correlate with intraparenchymal hematoma progression (HP) and worse outcomes in patients with spontaneous intracerebral hemorrhage (sICH). However, this association has not been elucidated in patients with traumatic intraparenchymal hemorrhage or contusion (tIPH). We hypothesized that 24 h-BPV from time of admission is associated with hemorrhagic progression of contusion or intraparenchymal hemorrhage (HPC), and worse outcomes in patients with tIPH.We performed a retrospective observational analysis of adult patients treated at an academic regional Level 1 trauma center between 01/2018-12/2019. We included patients who had tIPH and ≥ 2 computer tomography (CT) scans within 24 h of admission. HP, defined as ≥30% of admission hematoma volume, was calculated by the ABC/2 method. We performed stepwise multivariable logistic regressions for the association between clinical factors and outcomes.We analyzed 354 patients' charts. Mean age (Standard Deviation [SD]) was 56 (SD = 21) years, 260 (73%) were male. Mean admission hematoma volume was 7 (SD =19) cubic centimeters (cmSBP

Introduction: The presence of band cells > 10% of the total white blood cell (WBC) count (“bandemia”) is often used as an indicator of serious bacterial illness (SBI). Results from studies of bandemia as a predictor of SBI were conflicting and little is known about the relationship between severe bandemia (SB) and clinical outcomes from SBI in children. We hypothesized that SB (band level > 20%) is not associated with adverse outcomes in an emergency department (ED) pediatric population. Methods: Medical records from children between the ages of two months and 18 years with SB who presented to a tertiary referral regional hospital were studied. Outcomes were categorized as severe adverse events (SAEs) or moderate adverse events (MAEs). Multivariate logistic regressions were used to assess the association between SB and outcomes. Results: We analyzed 102 patients. Mean age (standard deviation, SD) was 5.25 (0.5) years, 18 (18%) had MAE, 21 (21%) had SAE, and no patients died. Mean band levels were similar between groups: no adverse events 28 (10) vs. SAE 31 (9) vs. MAE 27 (8), p=0.64. Multivariate logistic regressions showed SB was not associated with any adverse events (odds ratio (OR) 1.04, 95% confidence interval (CI) 0.9-1.1, p=0.27). Non-normal X-ray (XR) (OR 17, 95% CI 3.3-90, p
