Epidemiology and prognosis of anti-infective therapy in the ICU setting during acute pancreatitis: a cohort study

Abstract Background Recent international guidelines for acute pancreatitis (AP) recommend limiting anti-infective therapy (AIT) to cases of suspected necrotizing AP or nosocomial extrapancreatic infection. Limited data are available concerning empirical and documented AIT prescribing practices in patients admitted to the intensive care unit (ICU) for the management of AP. Methods Using a multicentre, retrospective (2009–2014), observational database of ICU patients admitted for AP, our primary objective was to assess the incidence of AIT prescribing practices during the first 30 days following admission. Secondary objectives were to assess the independent impact of centre characteristics on the incidence of AIT and to identify factors associated with crude hospital mortality in a logistic regression model. Results In this cohort of 860 patients, 359 (42%) received AIT on admission. Before day 30, 340/359 (95%) AIT patients and 226/501 (45%) AIT-free patients on admission received additional AIT, mainly for intra-abdominal and lung infections. A large heterogeneity was observed between centres in terms of the incidence of infections, therapeutic management including AIT and prognosis. Administration of AIT on admission or until day 30 was not associated with an increased mortality rate. Patients receiving AIT on admission had increased rates of complications (septic shock, intra-abdominal and pulmonary infections), therapeutic (surgical, percutaneous, endoscopic) interventions and increased length of ICU stay compared to AIT-free patients. Patients receiving delayed AIT after admission and until day 30 had increased rates of complications (respiratory distress syndrome, intra-abdominal and pulmonary infections), therapeutic interventions and increased length of ICU stay compared to those receiving AIT on admission. Risk factors for hospital mortality assessed on admission were age (adjusted odds ratio [95% confidence interval] 1.03 [1.02–1.05]; p < 0.0001), Balthazar score E (2.26 [1.43–3.56]; p < 0.0001), oliguria/anuria (2.18 [1.82–4.33]; p < 0.0001), vasoactive support (2.83 [1.73–4.62]; p < 0.0001) and mechanical ventilation (1.90 [1.15–3.14]; p = 0.011), but not AIT (0.63 [0.40–1.01]; p = 0.057). Conclusions High proportions of ICU patients admitted for AP receive AIT, both on admission and during their ICU stay. A large heterogeneity was observed between centres in terms of incidence of infections, AIT prescribing practices, therapeutic management and outcome. AIT reflects the initial severity and complications of AP, but is not a risk factor for death.

Abstract Background: Gastroscopy is a useful procedure for gastrointestinal (GI) bleeding. No definite clinical guidelines recommend on the choice of gastroscopy implementation in the intensive care unit (ICU) patient with suspected GI bleeding. The objective of this retrospective study was to compare the clinical effectiveness of gastroscopy in critically ill patients using high-dose proton pump inhibitor for suspected bleeding.Methods: ICU patients using a high-does proton pump inhibitor for suspected GI bleeding from January 2015 to February 2020 were retrospectively included. Massive GI bleeding, such as hematemesis and hematochezia, were excluded. After propensity score matching (PSM) between the gastroscopy and no gastroscopy groups, the change in hemoglobin level, requirement of RBC transfusion, length of ICU stay, and ICU mortality were compared. Results: Of the 116 subjects included, 34 patients had gastroscopy during ICU stay. Among the gastroscopy group, 13 (38.2%) patients showed normal findings, and the most frequent abnormal finding was gastric ulcer (n = 9, 26.5%), and 12 patients (35.3%) had a hemostatic procedure. After PSM, the gastroscopy group needed more red blood cell transfusion than the no-gastroscopy group (P = 0.01). There was no significant difference in the change in hemoglobin level (P = 0.10), length of ICU stay (P = 0.64), and ICU mortality (P = 0.55).Conclusion: This retrospective study showed that gastroscopy had no definite clinical benefit in ICU patients using high-dose proton pump inhibitor for suspected GI bleeding.

Abstract Background Delirium is an important independent predictor of negative clinical outcomes in intensive care unit (ICU) patients. The purpose of this study was to investigate the territorial incidence of ICU delirium, its related risk factors, and short-term outcomes in Shandong Province, China, to provide precise information for territorial patient management. Methods A multicenter prospective observational study was conducted. Patients with delirium were defined as any patient with at least one positive CAM-ICU or ICDSC assessment. Demographics, admission clinical data, daily interventions provided to patients and environmental factors were collected. Results From May 1, 2018 to Jan 31, 2020, 536 noncomatose patients were ultimately eligible for the study. One hundred eighteen patients (22%) experienced delirium at least once. In the univariate analysis, age (p = 0.009), SOFA score (p = 0.006), a history of cerebrovascular disease (p = 0.044) and impaired renal function (p = 0.003) were risk factors for delirium. Most therapeutic interventions were linked to delirium in the univariate analysis, including enteral nutrition (p = 0.000), artificial airway (p = 0.021), nasogastric tube (p = 0.001), use of restraint straps (p = 0.000), and use of sedative medications, including midazolam (p = 0.003), propofol (p = 0.032) and butorphanol (p = 0.028). Among the patient’s vital signs and laboratory examinations performed on the day of assessment, body temperature, BUN levels and CRP levels were risk factors for delirium. Midazolam use, chronic renal insufficiency, physical restraints, nosogastric tube, enteral nutrition, and CRP and BUN levels were factors associated with an increased risk of delirium in the multivariate analysis. The durations of mechanical ventilation and ICU stay in patients with delirium was significantly higher than those in patients without delirium [8 (IQR: 4–14) vs 5 (IQR: 3–10) and 9 (IQR: 4–17) vs 6 (IQR: 4–12), p < 0.05]. Conclusions Delirium was associated with prolonged mechanical ventilation and a prolonged ICU stay. Based on the findings from this study, we should not only reduce the use of sedatives and analgesics but also minimize invasive operations, including the placement of nasogastric tubes, to recover eternal nutrition for ICU patients and avoid physical restraints as much as possible to prevent delirium. Trial registration: This study was registered in the Chinese Clinical Trial Registry (ChiCTR1900021360).

Abstract Introduction Ventilator-associated pneumonia (VAP) is reported as the second most common nosocomial infection among critically ill patients with the incidence ranging from 2 to 16 episodes per 1000 ventilator days. The use of probiotics has been shown to have a promising effect in many RCTs. Our systematic review and meta-analysis were thus planned to determine the effect of probiotic use in critically ill ventilated adult patients on the incidence of VAP, length of hospital stay, length of ICU stay, duration of mechanical ventilation, the incidence of diarrhea, and the incidence of oropharyngeal colonization and in-hospital mortality. Methodology Systematic search of various databases (such as Embase, Cochrane, and Pubmed), published journals, clinical trials, and abstracts of the various major conferences were made to obtain the RCTs which compare probiotics with placebo for VAP prevention. The results were expressed as risk ratios or mean differences. Data synthesis was done using statistical software - Review Manager (RevMan) Version 5.4 (The Cochrane Collaboration, 2020). Results Nine studies met our inclusion criterion and were included in the meta-analysis. The incidence of VAP (risk ratio: 0.70, CI 0.56, 0.88; P = 0.002; I2 = 37%), duration of mechanical ventilation (mean difference −3.75, CI −6.93, −0.58; P 0.02; I2 = 96%), length of ICU stay (mean difference −4.20, CI −6.73, −1.66; P = 0.001; I2 = 84%) and in-hospital mortality (OR 0.73, CI 0.54, 0.98; P = 0.04; I2 = 0%) in the probiotic group was significantly lower than that in the control group. Probiotic administration was not associated with a statistically significant reduction in length of hospital stay (MD −1.94, CI −7.17, 3.28; P = 0.47; I2 = 88%), incidence of oro-pharyngeal colonization (OR 0.59, CI 0.33, 1.04; P = 0.07; I2 = 69%), and incidence of diarrhea (OR 0.59, CI 0.34, 1.03; P = 0.06; I2 = 38%). Discussion Our meta-analysis shows that probiotic administration has a promising role in lowering the incidence of VAP, the duration of mechanical ventilation, length of ICU stay, and in-hospital mortality.

Duration Of Ventilation

Abstract Background: The application of high PEEP remains to be a controversial issue when it comes to ICU patients underwent ventilation. There are studies supporting the usage of high PEEP in patients with ARDS, while for those without ARDS, the conclusion is of great ambiguity. We performed this systematic review and meta-analysis to compare the effects of high and low level of PEEP on ICU patients without ARDS.Methods: We searched public databases (including PubMed, EMBASE, Cochrane Library and Clinicaltrial.gov) to find eligible randomized controlled trials (RCTs). The primary outcomes included in this meta-analysis were in-hospital mortality, 28-day mortality and the duration of ventilation, ICU stay, and hospital stay. We used the Cochrane risk of bias assessment tool to evaluate risk of bias. Trial Sequential Analysis (TSA) was conducted. Results: We included 2307 patients from 24 trials using high and low PEEP. Although no significant difference was found between high and low PEEP applications in in-hospital mortality (risk ratio[RR] 0.98, 95% confidence interval[CI] [0.81, 1.19], P=0.87), 28-day mortality (RR 0.68, 95% CI [0.33, 1.40], P=0.30) and the duration of ventilation (mean difference[MD] -0.30, 95% CI [-0.64, 0.04], P=0.09), ICU stay (MD -0.38, 95% CI [-1.03, 0.27], P=0.25), and hospital stay (MD -0.56, 95% CI [-1.44, 0.32], P=0.22), high PEEP indeed increased the level of PaO2/FIO2 (MD 32.39, 95% CI [13.06, 51.72], P=0.001), and therefore decreased the incidences of ARDS (RR 0.57, 95% CI [0.37, 0.89], P=0.01) and hypoxaemia (RR 0.60, 95% CI [0.41, 0.88], P=0.009). In addition, although total results did not reveal the advantage of high PEEP on other secondary outcomes regarding atelectasis, barotrauma, ventilator associated pneumonia (VAP), hypotension, mean arterial pressure (MAP), SaO2 and lactate, subgroup analysis seemed to obtain different results. The TSA results suggested more RCTs were needed. Conclusion: Ventilation with high PEEP in ICU patients without ARDS may improve the level of oxygenation (PaO2/FIO2) resulting in low incidences of ARDS and hypoxaemia. Nevertheless, other clinical outcomes including in-hospital and 28-day mortality, duration of ventilation, ICU stay and hospital stay, pulmonary complications, hemodynamics and post-operative fluid balance did not show any significant difference.

Length Of Icu Stay

Abstract Background: Machine learning can predict outcomes and determine variables contributing to precise prediction, and can thus classify patients with different risk factors of outcomes. This study aimed to investigate the predictive accuracy for mortality and length of stay in intensive care unit (ICU) patients using machine learning, and to identify the variables contributing to the precise prediction or classification of patients.Methods: Patients (n=12,747) admitted to the ICU at Chiba University Hospital were randomly assigned to the training and test cohorts. After learning using the variables on admission in the training cohort, the area under the curve (AUC) was analyzed in the test cohort to evaluate the predictive accuracy of the supervised machine learning classifiers, including random forest (RF) for outcomes (primary outcome, mortality; secondary outcome, and length of ICU stay). The rank of the variables that contributed to the machine learning prediction was confirmed, and cluster analysis of the patients with risk factors of mortality was performed to identify the important variables associated with patient outcomes.Results: Machine learning using RF revealed a high predictive value for mortality, with an AUC of 0.945. In addition, RF showed high predictive value for short and long ICU stays, with AUCs of 0.881 and 0.889, respectively. Lactate dehydrogenase (LDH) was identified as a variable contributing to the precise prediction in machine learning for both mortality and length of ICU stay. LDH was also identified as a contributing variable to classify patients into sub-populations based on different risk factors of mortality.Conclusion: The machine learning algorithm could predict mortality and length of stay in ICU patients with high accuracy. LDH was identified as a contributing variable in mortality and length of ICU stay prediction and could be used to classify patients based on mortality risk.

Severity Scores

Abstract Background: The predictive value of disease severity scores for intensive care unit (ICU) patients is occasionally inaccurate because ICU patients with mild symptoms are also considered. We, thus, aimed to evaluate the accuracy of severity scores in predicting mortality of patients with complicated conditions admitted for > 24 hours. Methods: Overall, 35,353 adult patients using nationwide ICU data were divided into two groups: (1) overnight ICU stay after elective surgery and alive on discharge within 24 hours and (2) death within 24 hours or prolonged stay. The performance and accuracy of Sequential Organ Failure Assessment (SOFA), Acute Physiology and Chronic Health Evaluation (APACHE) II and III, and Simplified Acute Physiology Score (SAPS) II scores in predicting in-hospital mortality were evaluated. Results: In the overnight stay group, the correlation between SOFA and APACHE III scores or SAPS II was low because many had a SOFA score of 0. In the prolonged stay group, the predictive value of SAPS II and APACHE II and III showed high accuracy but that of SOFA was moderate. Conclusions: When overnight ICU stay patients were not included, the high predictive value for in-hospital mortality of SAPS II and APACHE II and III was evident.

Background: Sepsis and septic shock are leading causes of mortality world-wide. In patients outside the intensive care unit (ICU) a rising qSOFA (quick Sequential Organ Failure Assessment) score correlates with mortality risk. We sought to investigate if the duration of a qSOFA score ≥ 2 prior to ICU admission further affects outcomes, namely: ICU mortality, in-hospital mortality and length of ICU stay. Method: A retrospective chart review was performed using the electronic ICU database at a quaternary level hospital in Durban, KwaZulu-Natal, examining entries from 1 January 2008 to 31 December 2017. The review included 235 emergency in-hospital adult admissions with suspected infection, of which 144 had a qSOFA score ≥ 2 prior to ICU admission. Results: There was no significant association between the duration of a qSOFA score ≥ 2 prior to ICU admission and ICU mortality (p = 0.975), in-hospital mortality (p = 0.918) and length of ICU stay until demise (p = 0.848) or discharge (p = 0.624). The qSOFA score was significantly associated with ICU mortality with scores of 0, 1, 2 and 3 resulting in ICU mortality rates of 0%, 22.5%, 53.7% and 84.6% respectively (p < 0.001). Conclusion: The duration of a qSOFA score ≥ 2 prior to emergency ICU admission was not significantly associated with ICU mortality, in-hospital mortality or length of ICU stay in adults with suspected infection.

Introduction: Severe acute pancreatitis, according to Atlanta classification, is a heterogeneous group of patients with different outcomes. The patients with local complications and without organ failure have better outcome. This study has been conducted to determine the proportion of moderately severe acute pancreatitis and validate this subgroup in our population of patients.Methods: A total of 172 patients with the diagnosis of acute pancreatitis were categorized into three groups according to presence or absence of local complications and organ failure as mild acute pancreatitis, moderately severe acute pancreatitis and severe acute pancreatitis and were compared in terms of need for intensive care unit care, length of ICU stay, need for intervention, length of hospital stay and mortality.Results: Fifty seven (33%) were categorized as moderately severe acute pancreatitis. Need for ICU care (19.3% vs 100%, p < 0.001), length of ICU stay (1 vs 9.8 days, p < 0.001), length of hospital stay (8.3±3.7 vs 16.6±8.1 days, p < 0.001) and mortality (0% vs 33.3%, p < 0.001) between moderately severe acute pancreatitis and severe acute pancreatitis was significantly different. Moreover, mild acute pancreatitis and moderately severe acute pancreatitis had no mortality.Conclusions: This study showed that moderately severe acute pancreatitis exists as a separate group different from mild acute pancreatitis and severe acute pancreatitis with no mortality as in mild acute pancreatitis.

SummaryIntroduction. Thrombocytopenia is frequently encountered in intensive care unit (ICU) patients. The cause of thrombocytopenia is multifactorial, it develops as a result of infection, inflammation and depletion of coagulation factors. Therefore, thrombocytopenia could potentially serve as an indicator of severity of the illness and an outcome predictor in patients with severe community-acquired pneumonia (CAP).Aim of the study. To determine incidence and predictive value of thrombocytopenia in ICU patients with severe CAP.Material and methods. We carried out a retrospective study based on clinical records from patients admitted to the Pauls Stradins Clinical University Hospital Intensive Care and Reanimation Unit from 2011 to 2014. Thrombocytopenia was defined as platelet count ≤150×109/L.Results. A total of 98 patients were included in this study, 58 (59%) men and 40 (41%) women. The mean (±SD) age of patients was 61±17.9 years, 54% died and 46% survived. 57 patients (58%) developed thrombocytopenia, in 58% it was present at the admission to ICU, and 42% developed thrombocytopenia during their stay in ICU. The lowest platelet count, in survivors was on fifth day in ICU, while in non-survivors on fourth day in ICU. Platelet count on admission to ICU (ROC AUC: 0.610, p=0.095) had lower discriminative power for ICU mortality than SOFA score (ROC AUC: 0.729, p=0.001) and CURB-65 score (ROC AUC: 0.680, p=0.006). Patients with thrombocytopenia at any point of ICU stay had higher hospital mortality in comparison to patients without thrombocytopenia. (36 (63.1%) vs 17 (41.1%), p=0.041). In thrombocytopenic patients non-resolution of thrombocytopenia during the ICU stay was associated with higher mortality (OR 5.5; 95% CI, 1.6-18.7, p=0.006). After adjusting for age, gender and SOFA score, non-resolution of thrombocytopenia remained to be an independent mortality predictor (OR 8, 95% CI 1.7-37, p=0.008)Conclusions. Thrombocytopenia is frequently encountered in patients with severe CAP. Thrombocytopenia at any point of ICU stay is associated with higher hospital mortality. Resolution of thrombocytopenia is associated with better clinical outcome.
