Abstract Background Spontaneous bacterial peritonitis (SBP) is a serious complication of variceal hemorrhage. Guidelines recommend a maximum of seven days of antibiotics after variceal hemorrhage to prevent SBP and reduce rates of rebleeding and mortality. However, studies supporting these guidelines used varied durations of therapy including those with less than seven days. The objective of this study was to determine if less than seven days of antibiotic prophylaxis was noninferior to seven or more days in patients with cirrhosis and variceal hemorrhage. Methods This was a single-center, retrospective cohort conducted from August 2019 to August 2020 including adult patients who received treatment for variceal hemorrhage and antibiotics for prevention of SBP during hospitalization. Patients were excluded if they were diagnosed with non-variceal hemorrhage, received treatment with antibiotics within 72 hours prior to the variceal hemorrhage, or expired or transitioned to end of life care within 48 hours of hospital admission. The primary outcome was in-hospital mortality. Secondary outcomes included SBP within the first 30 days after variceal hemorrhage, 30-day mortality, 30-day readmission rate, incidence of rebleeding at seven and 30 days, incidence of Clostridioides difficile infection, and intensive care unit and hospital length of stay. Results 64 patients were included with 45 patients in the less than seven days group and 19 patients in the seven or more days of antibiotic prophylaxis group. In each group, patients were primarily male with a median age of approximately 60 years. There was no difference in the primary outcome of in-hospital mortality between the less than seven days group as compared to the seven or more days group (22.2% vs 0%, p=1). No difference was identified between the less than seven days group as compared to the seven or more days group for any of the secondary outcomes. Conclusion This study identified no difference in patient-centered outcomes when comparing less than seven days of prophylactic antibiotics to seven or more days in patients with variceal hemorrhage. Less than seven days of prophylactic antibiotics may be a reasonable duration for prevention of SBP. Disclosures All Authors: No reported disclosures

IntroductionDiarrhoea is a frequent concern in the intensive care unit (ICU) and is associated with prolonged mechanical ventilation, increased length of ICU stay, skin breakdown and renal dysfunction. However, its prevalence, aetiology and prognosis in the critically ill have been poorly studied. The primary objectives of this study are to determine the incidence, risk factors and consequences of diarrhoea in critically ill adults. The secondary objectives are to estimate the incidence ofClostridium difficile-associated diarrhoea (CDAD) in ICU patients and to validate the Bristol Stool Chart and Bliss Stool Classification System characterising bowel movements in the ICU. Our primary outcome is the incidence of diarrhoea . Our secondary outcomes include: CDAD, ICU and hospital mortality and ICU and hospital length of stay.Methods and analysisThis international prospective cohort study will enrol patients over 10 weeks in 12 ICUs in Canada, the USA, Poland and Saudi Arabia. We will include all patients 18 years of age and older who are admitted to the ICU for at least 24 hours and follow them daily until ICU discharge. Our primary outcome is the incidence of diarrhoea based on the WHO definition, during the ICU stay. Our secondary outcomes include: CDAD, ICU and hospital mortality and ICU and hospital length of stay. We will use logistic regression to identify factors associated with diarrhoea (as defined using WHO criteria) and the kappa statistic to measure agreement on diarrhoea rates between the WHO definition and the Bristol Stool Chart and Bliss Stool Classification System.Ethics and disseminationThe protocol has been approved by the research ethics board of all participating centres. The diarrhoea interventions, consequences and epidemiology in the intensive care unit (DICE-ICU) study will generate evidence about diarrhoea and its frequency, predisposing factors and consequences, to inform critical care practice and future research.Lay summaryDiarrhoea is a frequent clinical problem for hospitalised patients including those who are critically ill in the ICU. Diarrhoea can cause complications such as skin damage, dehydration and kidney problems. It is not clear how common diarrhoea is in the ICU, the factors that cause it or the best way for clinicians to assess it. The DICE-ICU study is an international prospective observational study to examine the frequency, risk factors and outcomes of diarrhoea during critical illness.

Abstract Background In neutropenic patients, a fever may be the only indication of a severe underlying infection. According to the National Comprehensive Cancer Network (NCCN) guidelines, for high-risk patients, monotherapy with an anti-pseudomonal β-lactam agent should be initiated. NCCN states emerging data may support extended or continuous infusions of β-lactam therapies; however, preference is not given for cefepime or piperacillin/tazobactam. The objective of this study was to compare the outcomes of extended infusions of piperacillin/tazobactam vs. cefepime for the empiric treatment of neutropenic fever. Methods This retrospective, single-center cohort study included patients ≥18 years with an absolute neutrophil count (ANC) less than 500 cells/mm3, single oral temperature measurement ≥38.3°C or ≥38°C sustained over 1 hour period and admitted to a bone marrow transplant unit. Patients received extended infusion piperacillin/tazobactam or cefepime as initial antibiotic therapy for at least 48 hours between January 1, 2015 and September 1, 2018. The primary outcome was time to defervescence in hours. Secondary outcomes included time to defervescence and no acetaminophen use within 8 hours, defervescence by 72 hours, hospital length of stay, clinical failure, in-hospital mortality, and acute kidney injury. Results 73 patients were included in this study (36 received piperacillin/tazobactam and 37 received cefepime). The primary outcome of median time to defervescence was 31.8 hours in the piperacillin/tazobactam group and 25 hours in the cefepime group (P = 0.26). Secondary outcomes in the piperacillin/tazobactam group compared with cefepime, respectively included median time to defervescence and no acetaminophen use: 43 vs. 35 hours (P = 0.16), defervescence by 72 hours: 66.7% vs. 91.9% (P = 0.01), median hospital length of stay 28 vs. 22 days (P = 0.04), clinical failure 22.2% vs. 24.3% (P = 0.83), in-hospital mortality 8.3% vs. 2.8% (P = 0.36), rate of acute kidney injury: 50% vs. 24.3% (P = 0.02). Conclusion These findings suggest there is no difference in time to defervescence between extended infusions of piperacillin/tazobactam compared with extended infusions of cefepime for the empiric treatment of neutropenic fever.

Abstract Background At the time of this writing, there is no FDA approved medication for the treatment of COVID-19. One medication currently under investigation for COVID-19 treatment is tocilizumab, an interleukin-6 (IL-6) inhibitor. It has been shown there are increased levels of cytokines including IL-6 in severe COVID-19 hospitalized patients attributed to cytokine release syndrome (CRS). Therefore, inhibition of IL-6 receptors may lead to a reduction in cytokines and prevent progression of CRS. The purpose of this retrospective study is to utilize a case-matched design to investigate clinical outcomes associated with the use of tocilizumab in severe COVID-19 hospitalized patients. Methods This was a retrospective, multi-center, case-matched series matched 1:1 on age, BMI, and days since symptom onset. Inclusion criteria included ≥ 18 years of age, laboratory confirmed positive SARS-CoV-2 result, admitted to a community hospital from March 1st – May 8th, 2020, and received tocilizumab while admitted. The primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay, total mechanical ventilation days, mechanical ventilation mortality, and incidence of secondary bacterial or fungal infections. Results The following results are presented as tocilizumab vs control respectively. The primary outcome of in-hospital mortality for tocilizumab (n=26) vs control (n=26) was 10 (38%) vs 11 (42%) patients, p=0.777. The median hospital length of stay for tocilizumab vs control was 14 vs 11 days, p=0.275. The median days of mechanical ventilation for tocilizumab (n=21) vs control (n=15) was 8 vs 7 days, p=0.139, and the mechanical ventilation mortality was 10 (48%) vs 9 (60%) patients, p=0.463. In the tocilizumab group, for those expired (n=10) vs alive (n=16), 10 (100%) vs 7 (50%) patients respectively had a peak ferritin > 600 ng/mL, and 6 (60%) vs 8 (50%) patients had a peak D-dimer > 2,000 ng/mL. The incidence of secondary bacterial or fungal infections within 7 days of tocilizumab administration occurred in 5 (19%) patients. Conclusion These findings suggest that tocilizumab may be a beneficial treatment modality for severe COVID-19 patients. Larger, prospective, placebo-controlled trials are needed to further validate results. Disclosures Christian Cheatham, PharmD, BCIDP, Antimicrobial Resistance Solutions (Shareholder)

Abstract Background: Traumatic brain injury (TBI) can induce early or late post-traumatic seizures (PTS). While PTS incidence is low, prophylaxis is used despite a lack of consensus on agent or duration. Levetiracetam (LEV) for early PTS prophylaxis is preferred due to its safety and efficacy. The purpose of this study was to evaluate LEV for early PTS prophylaxis.Methods: A single-center, retrospective chart review of TBI patients > 18 years who received LEV for early PTS prophylaxis between August 2018 - July 2019. The primary outcome was LEV duration. Secondary outcomes were incidence of seizure, intensive care unit (ICU) and hospital length of stay (LOS).Results: Of the 137 included, mean age was 59±20 years and 69.3% were male. The mean admission GCS was 13±4 and 77.4% had mild TBI. Median LEV duration was 7 (IQR 4-10) days and 13.9% met recommended 7-day duration. Those prescribed LEV > 7 days had more than twice the median LEV duration than those prescribed ≤ 7 days (10.25 (8.5-15.5) vs 4 (1.5-4.5) days, p < 0.0001). EEG-confirmed PTS occurred in 2.2%, with an early PTS incidence of 0.73%. Median ICU and hospital LOS were 2 (IQR 1-7) and 7 (IQR 3-16) days, respectively. Conclusions: The incidence of PTS was low as most patients in our study had mild or moderate TBI. Early PTS prophylaxis with LEV for 7 days is appropriate, although the majority of patients did not meet the recommended duration. Efforts to standardize and implement PTS prophylaxis protocols are needed.

Purpose To determine the impact of Clostridioides difficile infection (CDI) treatment duration on CDI recurrence in hematology/oncology patients receiving concurrent non-CDI antibiotics. Patients and methods This multi-site, retrospective study examined hematology/oncology patients age ≥18 years hospitalized with active CDI who received ≥1 dose of concurrent non-CDI antibiotics between September 2013 and June 2019. All patients were classified by two definitions for statistical analysis: standard (10-14 days) versus prolonged (>14 days) duration of CDI treatment and non-extended (≤24 hours after stopping non-CDI antibiotics) versus extended (>24 hours after stopping non-CDI antibiotics) CDI treatment. Primary outcome was CDI recurrence within 180 days of completing CDI treatment. Secondary outcomes included hospital length of stay (LOS) as well as mortality and incidence of vancomycin-resistant enterococcus (VRE) infections at 180 days. Results Of the 198 patients included, 112 were classified as prolonged versus 86 standard duration and 138 were classified as extended versus 60 non-extended duration. After accounting for demographic differences, no difference existed in the primary outcome of CDI recurrence in either prolonged versus standard or extended versus non-extended analysis (all p > 0.05). Patients who received prolonged versus standard CDI treatment had longer LOS (p < 0.0001) while no difference existed in extended versus non-extended (p > 0.05). No difference in mortality existed in prolonged versus standard (p > 0.05) while those who received extended versus non-extended CDI treatment had significantly lower mortality (p = 0.0008). Conclusions Neither prolonging CDI treatment beyond standard duration nor extending duration beyond end of non-CDI antibiotics was associated with decreased CDI recurrence rate.

Abstract Background The optimal method for laboratory diagnosis of Clostridioides difficile infection (CDI) remains undefined and national guidelines do not make a recommendation for a preferred diagnostic algorithm. Aiming to improve infection control measures, the Hospital of the University of Pennsylvania changed its testing process for the diagnosis of CDI from a 3-step to a 2-step algorithm (Figure 1) in September 2018. Starting an algorithm with nucleic acid amplification testing (NAAT) has been hypothesized to lead to potential diagnostic uncertainty if the result is positive by NAAT alone, as this test cannot distinguish between active infection and colonization. Three-Step and Two-Step Diagnostic Testing Algorithms Methods This retrospective, single-center, quasi-experimental study included patients ≥ 18 years of age that tested positive for C. difficile between May 1st, 2018 and January 31st, 2019. The study period encompassed 4 months prior to the algorithm change, a 1-month washout immediately following the change, and the subsequent 4 months. The primary outcome was proportion of patients who tested positive for C. difficile and received targeted treatment for CDI. Secondary outcomes included total number of patients who tested positive for C. difficile and received targeted treatment for CDI, duration of treatment for CDI, and hospital length of stay. Results Sixty-nine patients in the pre-group (3-step) and 75 patients in the post-group (2-step) tested positive for C. difficile. A higher proportion of patients in the post-group tested positive by NAAT alone (59.4% vs. 73.3%). CDI severity and prior history of CDI were similar between groups. The primary outcome occurred in 89.9% of patients in the pre-group and 83.8% in the post-group (p=0.213). Sixty-two patients in each group received targeted treatment for CDI (p=0.213), median treatment duration was 15 (IQR 11.25-25.75) and 14 (IQR 11-25) days (p=0.505), and median hospital length of stay was 9 (IQR 3-15) and 6 (IQR 3-20) days (p=0.690) in the pre-group and post-group, respectively. Conclusion Although there was a higher percentage of patients in the post-group that tested positive for C. difficile by NAAT alone, there was no difference in the proportion or total number of patients who received targeted CDI treatment between time periods.

Background Historically, intravenous (IV) bisphosphonates with calcitonin are the treatment of choice for hypercalcemia of malignancy. However, evidence is lacking. Objective The objective of this study was to compare the use of bisphosphonate versus bisphosphonate with calcitonin for moderate to severe hypercalcemia of malignancy. Methods This was a retrospective study evaluating patients who received bisphosphonate and/or calcitonin for treatment of moderate to severe hypercalcemia of malignancy. Patients received usual care plus either (1) bisphosphonate or (2) bisphosphonate with calcitonin. The primary outcome was change in corrected serum calcium concentrations 48 hours after treatment. Secondary outcomes included corrected calcium levels, incidence of normocalcemia and hypocalcemia, time to normocalcemia, hospital length of stay, and cost avoidance. Results The 48-hour decrease in corrected calcium was less in the bisphosphonate group than in the combination group (2.4 [1.6-3.4] vs 3.9 [3.5-5.3]; P < 0.001). However, initial calcium levels in the combination group were higher than in the bisphosphonate group, and calcium levels at 24, 48, and 72 hours were similar. Secondary outcomes did not differ. Average cost avoidance with bisphosphonate monotherapy was $11 248 per patient and $291 448 per year. Conclusions and Relevance In the treatment of moderate to severe hypercalcemia of malignancy, IV bisphosphonate in combination with calcitonin resulted in a higher difference in corrected calcium levels at 48 hours compared with bisphosphonate therapy alone. However, corrected calcium levels in the first 72 hours, time to normocalcemia, and clinical outcomes were similar. The addition of calcitonin increases cost without substantial clinical benefit, and providers may consider avoiding calcitonin.

Background: Data from Clostridium difficile infection (CDI) in neutropenic patients are still scarce. Objective: To assess outcomes of CDI in patients with and without neutropenia. Methods: The study included a retrospective cohort of adult patients at 3 academic hospitals between January 2013 and December 2017. The 2 study arms were neutropenic patients (neutrophil count <500/mm3) and nonneutropenic patients with confirmed CDI episodes. The primary outcome evaluated the composite end point of all-cause in-hospital mortality, intensive care unit (ICU) admissions, and treatment failure at 7 days. The secondary outcome evaluated hospital length of stay. Results: Of 962 unique cases of CDI, 158 were neutropenic (59% men) and 804 were nonneutropenic (46% men). The median age was 57 years (IQR, 44–64) in the neutropenic group and 68 years (IQR, 56–79) in the nonneutropenic group. The median Charlson comorbidity score was 5 (IQR, 3–7.8) and 4 (IQR, 3–5) in the neutropenic and nonneutropenic groups, respectively. Regarding severity, 88.6% versus 48.9% were nonsevere, 8.2% versus 47% were severe, and 3.2% versus 4.1% were fulminant in the neutropenic and nonneutropenic groups, respectively. Also, 63% of patients (60.9% in nonneutropenic, 65.2% in neutropenic) were exposed to proton-pump inhibitors. A combination CDI treatment was required in 53.2% of neutropenic patients and 50.1% of nonneutropenic patients. The primary composite end point occurred in 27% of neutropenic patients versus 22% of nonneutropenic patients (P = .257), with an adjusted odds ratio of 1.30 (95% CI, 0.84–2.00). The median hospital length of stay after controlling for covariates was 21.3 days versus 14.2 days in the neutropenic and nonneutropenic groups, respectively (P < .001). Complications (defined as hypotension requiring vasopressors, ileus, or bowel perforation) were seen in 6.0% of the nonneutropenic group and 4.4% of the neutropenic group (P = .574), with an adjusted odds ratio of 0.61 (95% CI, 0.28–1.45). Conclusions: Neutropenic patients were younger and their cases were less severe; however, they had lower incidences of all-cause in-hospital mortality, ICU admissions, and treatment failure. Hospital length of stay was significantly shorter in the neutropenic group than in the nonneutropenic group.Funding: NoneDisclosures: None

Purpose To compare in-hospital mortality and other hospitalization related outcomes of elevated risk patients (Pulmonary Embolism Severity Index [PESI] score of 4 or 5, and, European Society of Cardiology [ESC] classification of intermediate-high or high risk) with acute central pulmonary embolism (PE) treated with mechanical thrombectomy (MT) using the Inari FlowTriever device versus those treated with routine care (RC). Materials and Methods Retrospective data was collected of all patients with acute, central PE treated at a single institution over 2 concurrent 18-month periods. All collected patients were risk stratified using the PESI and ESC Guidelines. The comparison was made between patients with acute PE with PESI scores of 4 or 5, and, ESC classification of intermediate-high or high risk based on treatment type: MT and RC. The primary endpoint evaluated was in-hospital mortality. Secondary endpoints included intensive care unit (ICU) length of stay, total hospital length of stay, and 30-day readmission. Results Fifty-eight patients met inclusion criteria, 28 in the MT group and 30 in the RC group. Most RC patients were treated with systemic anticoagulation alone (24 of 30). In-hospital mortality was significantly lower for the MT group than for the RC group (3.6% vs 23.3%, P < .05), as was the average ICU length of stay (2.1 ± 1.2 vs 6.1 ± 8.6 days, P < .05). Total hospital length of stay and 30-day readmission rates were similar between MT and RC groups. Conclusion Initial retrospective comparison suggests MT can improve in-hospital mortality and decrease ICU length of stay for patients with acute, central PE of elevated risk (PESI 4 or 5, and, ESC intermediate-high or high risk).

Background and Aims: Cardiac injuries are highly lethal lesions following trauma and most of the patients decease in pre-hospital settings. However, studies on cardiac trauma in Estonia are scarce. Thus, we set out to study cardiac injuries admitted to Estonian major trauma facilities during 23 years of Estonian independence. Materials and Methods: After the ethics review board approval, all consecutive patients with cardiac injuries per ICD-9 (861.0 and 861.1) and ICD-10 codes (S.26) admitted to the major trauma facilities between 1 January 1993 and 31 July 2016 were retrospectively reviewed. Cardiac contusions were excluded. Data collected included demographics, injury profile, and in-hospital outcomes. Primary outcome was mortality. Secondary outcomes were cardiac injury profile and hospital length of stay. Results: During the study period, 37 patients were included. Mean age was 33.1 ± 12.0 years and 92% were male. Penetrating and blunt trauma accounted for 89% and 11% of the cases, respectively. Thoracotomy and sternotomy rates for cardiac repair were 80% and 20%, respectively. Most frequently injured cardiac chamber was left ventricle at 49% followed by right ventricle, right atrium, and left atrium at 34%, 17%, and 3% of the patients, respectively. Multi-chamber injury was observed at 5% of the cases. Overall hospital length of stay was 13.5 ± 16.7 days. Overall mortality was 22% (n = 8) with uniformly fatal outcomes following left atrial and multi-chamber injuries. Conclusion: Overall, 37 patients with cardiac injuries were hospitalized to national major trauma facilities during the 23-year study period. The overall in-hospital mortality was 22% comparing favorably with previous reports. Risk factors for mortality were initial Glasgow Coma Scale < 9, pre-hospital cardiopulmonary resuscitation, and alcohol intoxication.
