RESUMO

AIM: To explore the expression levels of miR-210, miR-137, and miR-153 in patients with acute cerebral infarction. Material and Methods. 76 patients with acute cerebral infarction treated in our hospital from April 2016 to October 2017 were enrolled as the observation group. Another 64 normal patients were selected as the control group. The patients were divided into the death and survival groups based on 1-year mortality of patients. qRT-PCR was used to detect the expression of miR-210, miR-137, and miR-153 in the serum of each group. Receiver operating characteristic (ROC) curve was employed to analyze the diagnostic value and predictive value of miR-210, miR-137 and miR-153 death in patients. The correlation between miR-210, miR-137, and miR-153 in the serum of the observation group was analyzed by Pearson's test. RESULTS: Levels of miR-210 and miR-137 in the observation group were significantly lower than those in the control group, while levels of miR-153 in the observation group were significantly higher than those in the control group (all P < 0.05). The ROC curve of diagnosis of acute cerebral infarction showed that the area under curve of miR-210 was 0.836, that of miR-137 was 0.843, and that of miR-153 was 0.842. The 1-year survival rate was 71.05%. The 1-year survival of the low-expression group of miR-210 and miR-137 was significantly lower than that of the high-expression group, while the 1-year survival of the low-expression group of miR-153 was significantly higher than that of the high-expression group (all P < 0.05). The ROC curve for predicting death showed that the area under curve of miR-210 was 0.786, that of miR-137 was 0.824, and that of miR-153 was 0.858. Pearson's correlation analysis showed that the expression of miR-210 was positively correlated with that of miR-137, while miR-137 was negatively correlated with that of miR-153 and miR-210 was negatively correlated with that of miR-153. CONCLUSION: miR-210, miR-137, and miR-153 have a certain value in the diagnosis and prediction of 1-year death of acute cerebral infarction and may be potential diagnostic and predictive indicators.

RESUMO

BACKGROUND & AIMS: Acutely ill older adults are at higher risk of malnutrition. This study aimed to explore the applicability and accuracy of the GLIM criteria to diagnose malnutrition in acutely ill older adults in the emergency ward (EW). METHODS: We performed a retrospective secondary analysis, of an ongoing cohort study, in 165 participants over 65 years of age admitted to the EW of a Brazilian university hospital. Nutrition assessment included anthropometry, the Simplified Nutritional Assessment Questionnaire (SNAQ), the Malnutrition Screening Tool (MST), and the Mini-Nutritional Assessment (MNA). We diagnosed malnutrition using GLIM criteria, defined by the parallel presence of at least one phenotypic [nonvolitional weight loss (WL), low BMI, low muscle mass (MM)] and one etiologic criterion [reduced food intake or assimilation (RFI), disease burden/inflammation]. We used the receiver operating characteristic (ROC) curves and Cox and logistic regression for data analyses. RESULTS: GLIM criteria, following the MNA-SF screening, classified 50.3% of participants as malnourished, 29.1% of them in a severe stage. Validation of the diagnosis using MNA-FF as a reference showed good accuracy (AUC = 0.84), and moderate sensitivity (76%) and specificity (75.1%). All phenotypic criteria combined with RFI showed the best metrics. Malnutrition showed a trend for an increased risk of transference to intensive care unit (OR = 2.08, 95% CI 0.99, 4.35), and severe malnutrition for in-hospital mortality (HR = 4.23, 95% CI 1.2, 14.9). CONCLUSION: GLIM criteria, following MNA-SF screening, appear to be a feasible approach to diagnose malnutrition in acutely ill older adults in the EW. Nonvolitional WL combined with RFI or acute inflammation were the best components identified and are easily accessible, allowing their potential use in clinical practice.

RESUMO

AIMS: To evaluate the acute and chronic patterns of myocardial injury among patients with coronavirus disease-2019 (COVID-19), and their mid-term outcomes. METHODS AND RESULTS: Patients with laboratory-confirmed COVID-19 who had a hospital encounter within the Mount Sinai Health System (New York City) between 27 February 2020 and 15 October 2020 were evaluated for inclusion. Troponin levels assessed between 72 h before and 48 h after the COVID-19 diagnosis were used to stratify the study population by the presence of acute and chronic myocardial injury, as defined by the Fourth Universal Definition of Myocardial Infarction. Among 4695 patients, those with chronic myocardial injury (n = 319, 6.8%) had more comorbidities, including chronic kidney disease and heart failure, while acute myocardial injury (n = 1168, 24.9%) was more associated with increased levels of inflammatory markers. Both types of myocardial injury were strongly associated with impaired survival at 6 months [chronic: hazard ratio (HR) 4.17, 95% confidence interval (CI) 3.44-5.06; acute: HR 4.72, 95% CI 4.14-5.36], even after excluding events occurring in the first 30 days (chronic: HR 3.97, 95% CI 2.15-7.33; acute: HR 4.13, 95% CI 2.75-6.21). The mortality risk was not significantly different in patients with acute as compared with chronic myocardial injury (HR 1.13, 95% CI 0.94-1.36), except for a worse prognostic impact of acute myocardial injury in patients <65 years of age (P-interaction = 0.043) and in those without coronary artery disease (P-interaction = 0.041). CONCLUSION: Chronic and acute myocardial injury represent two distinctive patterns of cardiac involvement among COVID-19 patients. While both types of myocardial injury are associated with impaired survival at 6 months, mortality rates peak in the early phase of the infection but remain elevated even beyond 30 days during the convalescent phase.

RESUMO

Previous studies have shown that lactate/albumin ratio (LAR) can be used as a prognostic biomarker to independently predict the mortality of sepsis and severe heart failure. However, the role of LAR as an independent prognostic factor in all-cause mortality in patients with acute respiratory failure (ARF) remains to be clarified. Therefore, we retrospectively analyzed 2170 patients with ARF in Medical Information Mart for Intensive Care Database III from 2001 to 2012. By drawing the receiver operating characteristic curve, LAR shows a better predictive value in predicting the 30-day mortality of ARF patients (AUC: 0.646), which is higher than that of albumin (AUC: 0.631) or lactate (AUC: 0.616) alone, and even higher than SOFA score(AUC: 0.642). COX regression analysis and Kaplan-Meier curve objectively and intuitively show that high LAR is a risk factor for patients with ARF, which is positively correlated with all-cause mortality. As an easy-to-obtain and objective biomarker, LAR deserves further verification by multi-center prospective studies.

RESUMO

BACKGROUND: In patients with established HF, low triiodothyronine syndrome (LT3S) is commonly present, and N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a useful marker for predicting death. This study was aimed to evaluate the prognostic value of LT3S in combination with NT-proBNP for risk of death in patients with heart failure (HF). METHODS: A total of 594 euthyroid patients hospitalized with acute decompensated HF were enrolled by design. Of these patients, 27 patients died during hospitalization and 100 deaths were identified in patients discharged alive during one year follow-up. Patients were divided into 2 groups on the base of the reference ranges of free T3 (FT3) levels: LT3S group (FT3 < 2.3pg/mL, n = 168) and non-LT3S group (FT3 ≥ 2.3pg/mL, n = 426). RESULTS: In multivariable Cox regression, LT3S was significantly associated with 1 year all-cause mortality (adjusted hazard ratio, 1.85; 95 % confidence interval [CI], 1.21 to 2.82; P = 0.005), but not significant for in-hospital mortality (adjusted hazard ratio, 1.58; 95 % CI, 1.58 to 2.82; P = 0.290) after adjustment for clinical variables and NT-proBNP. Addition of LT3S and NT-proBNP to the prediction model with clinical variables significantly improved the C statistic for predicting 1 year all-cause mortality. CONCLUSIONS: In patients with acute decompensated HF, the combination of LT3S and NT-proBNP improved prediction for 1 year all-cause mortality beyond established risk factors, but was not strong enough for in-hospital mortality.

RESUMO

BACKGROUND: During the coronavirus disease 2019 pandemic, New York instituted a statewide stay-at-home mandate to lower viral transmission. While public health guidelines advised continued provision of timely care for patients, disruption of safety-net health care and public fear have been proposed to be related to indirect deaths because of delays in presentation. We hypothesized that admissions for emergency general surgery (EGS) diagnoses would decrease during the pandemic and that mortality for these patients would increase. METHODS: A multicenter observational study comparing EGS admissions from January to May 2020 to 2018 and 2019 across 11 NYC hospitals in the largest public health care system in the United States was performed. Emergency general surgery diagnoses were defined using International Classification Diseases, Tenth Revision, codes and grouped into seven common diagnosis categories: appendicitis, cholecystitis, small/large bowel, peptic ulcer disease, groin hernia, ventral hernia, and necrotizing soft tissue infection. Baseline demographics were compared including age, race/ethnicity, and payor status. Outcomes included coronavirus disease (COVID) status and mortality. RESULTS: A total of 1,376 patients were admitted for EGS diagnoses from January to May 2020, a decrease compared with both 2018 (1,789) and 2019 (1,668) (p < 0.0001). This drop was most notable after the stay-at-home mandate (March 22, 2020; week 12). From March to May 2020, 3.3%, 19.2%, and 6.0% of EGS admissions were incidentally COVID positive, respectively. Mortality increased in March to May 2020 compared with 2019 (2.2% vs. 0.7%); this difference was statistically significant between April 2020 and April 2019 (4.1% vs. 0.9%, p = 0.045). CONCLUSION: Supporting our hypothesis, the coronavirus disease 2019 pandemic and subsequent stay-at-home mandate resulted in decreased EGS admissions between March and May 2020 compared with prior years. During this time, there was also a statistically significant increase in mortality, which peaked at the height of COVID infection rates in our population. LEVEL OF EVIDENCE: Epidemiological, level IV.

RESUMO

OBJECTIVE: To report the intra-operative adverse events (IOAEs) and the initial and one year outcomes of retrograde open mesenteric stenting (ROMS) using balloon expandable covered stents for acute and chronic mesenteric ischaemia. METHODS: Clinical data and outcomes of all consecutive patients treated with ROMS for acute and chronic mesenteric ischaemia at an intestinal stroke centre between November 2012 and September 2019 were reviewed. ROMS was performed using balloon expandable covered stents. Endpoints included IOAEs, in hospital mortality, post-operative complications, and re-interventions. One year overall survival, freedom from re-intervention, primary patency and assisted primary patency rates were analysed using the Kaplan-Meier time to event method. RESULTS: During the study period, 379 patients were referred to the centre for acute or chronic mesenteric ischaemia. Thirty-seven patients who underwent the ROMS procedure were included. All the patients had severe atherosclerotic mesenteric lesions. The ROMS technical success rate was 89% in this cohort. The rate of IOAEs was 19% and included four cases of retrograde recanalisation failure. All ROMS failures occurred in patients presenting with flush superior mesenteric artery occlusion and they were treated by mesenteric bypass. Ten patients (27%) underwent bowel resection, four of which resulted in a short bowel syndrome (11%). The in hospital mortality rate was 27%. Post-operative complications and re-intervention rates were 67% (n = 25) and 32% (n = 12), respectively. The median follow up was 20.2 months (interquartile range 29). The estimated one year overall survival for the cohort was 70.1% (95% confidence interval [CI] 52.5% - 82.2%). The estimated freedom from re-intervention at one year was 61.1% (95% CI 42.3 - 75.4). The one year primary patency and assisted primary patency rates were 84.54% (95% CI 63.34 - 94) and 92.4% (95% CI 72.8 - 98), respectively. CONCLUSION: ROMS procedures offer acceptable one year outcomes for mesenteric ischaemia but are associated with frequent stent related complications. Precise pre-operative planning, high quality imaging, and meticulous stent placement techniques may limit the occurrence of such events.

RESUMO

BACKGROUND: Prior reports have suggested that the red blood cell distribution width (RDW) parameter could be measured as a prognostic indicator in pulmonary embolism (PE) patients, thereby helping to guide their care. However, no systematic analyses on this topic have been completed to date, and the exact relationship between RDW and PE remains to be fully clarified. We will therefore conduct a systematic literature review with the goal of defining the correlation between RDW and mortality in acute PE cases. METHODS: The EMBASE, Web of Knowledge, PubMed, ClinicalTrials.gov, and Cochrane Library databases will be searched for all relevant studies published from inception through March 2021 using the following search strategy: ("red blood cell distribution width") AND ("pulmonary embolism"). Two authors will independently identify eligible studies and extract data. The Q and I2 statistics will be used to judge heterogeneity among studies. RESULTS: This study will establish the relative efficacy of RDW as a metric for predicting PE patient mortality. CONCLUSIONS: This study will offer a reliable, evidence-based foundation for the clinical utilization of RDW as a tool for gauging mortality risk in acute PE patients. ETHICS AND DISSEMINATION: As this is a protocol for a systematic review of previously published data, no ethical approval is required. Electronic dissemination of study results will be done through a peer-review publication or represented at a related conference.

RESUMO

Importance: The early identification of patients at high risk of clinical deterioration represents one of the greatest challenges for emergency medical services (EMS). Objective: To assess whether use of the ratio of prehospital oxygen saturation measured by pulse oximetry (Spo2) to fraction of inspired oxygen (Fio2) measured during initial contact by EMS with the patient (ie, the first Spo2 to Fio2 ratio) and 5 minutes before the patient's arrival at the hospital (ie, the second Spo2 to Fio2 ratio) can predict the risk of early in-hospital deterioration. Design, Setting, and Participants: A prospective, derivation-validation prognostic cohort study of 3606 adults with acute diseases referred to 5 tertiary care hospitals in Spain was conducted between October 26, 2018, and June 30, 2020. Eligible patients were recruited from among all telephone requests for EMS assistance for adults who were later evacuated with priority in advanced life support units to the referral hospitals during the study period. Main Outcomes and Measures: The primary outcome was hospital mortality from any cause within the first, second, third, or seventh day after EMS transport to the hospital. The main measure was the Spo2 to Fio2 ratio. Results: A total of 3606 participants comprised 2 separate cohorts: the derivation cohort (3081 patients) and the validation cohort (525 patients). The median age was 69 years (interquartile range, 54-81 years), and 2122 patients (58.8%) were men. The overall mortality rate of the patients in the study cohort ranged from 3.6% for 1-day mortality (131 patients) to 7.1% for 7-day mortality (256 patients). The best model performance was for 2-day mortality with the second Spo2 to Fio2 ratio with an area under the curve of 0.890 (95% CI, 0.829-0.950; P < .001), although the other outcomes also presented good results. In addition, a risk-stratification model was generated. The optimal cutoff resulted in the following ranges of Spo2 to Fio2 ratios: 50 to 100 for high risk of mortality, 101 to 426 for intermediate risk, and 427 to 476 for low risk. Conclusions and Relevance: This study suggests that use of the prehospital Spo2 to Fio2 ratio was associated with improved management of patients with acute disease because it accurately predicts short-term mortality.

RESUMO

BACKGROUND: Pulse wave velocity (PWV) is an excellent index of arterial stiffness and can be used to predict long-term cardiovascular (CV) outcome. In recent years, estimated PWV (ePWV), calculated by equations using age and mean blood pressure, was also reported to be a significant predictor of CV outcomes. However, there was no literature discussing about usefulness of ePWV in patients of acute myocardial infarction (AMI) for prediction of long-term CV and overall mortality. Therefore, we conducted this study for further evaluation. METHODS: A total of 187 patients with AMI admitted to cardiac care unit were enrolled. ePWV were calculated by the equations for each patient. RESULTS: The median follow-up to mortality was 73 months (25th-75th percentile: 8-174 months). There were 35 and 125 patients documented as CV and overall mortality, respectively. Under univariable analysis, ePWV could independently predict long-term CV and overall mortality. However, after multivariable analysis, ePWV could only predict long-term CV mortality in AMI patients. CONCLUSIONS: To the best of our knowledge, our study was the first to evaluate the usefulness of ePWV in AMI patients for prediction of long-term CV and overall mortality. Our study showed ePWV was not only easy to calculate by formula, but also an independent predictor for long-term CV mortality in univariable and multivariable analyses. Therefore, ePWV was a simple and useful tool to measure arterial stiffness and to predict CV mortality outcome in AMI patients without the necessity for equipment to measure PWV.

RESUMO

BACKGROUND: Liberal oxygen supplementation is often used in acute illness but has, in some studies, been associated with harm. RESEARCH QUESTION: The goal of this study was to assess the benefits and harms of higher vs lower oxygenation strategies in acutely ill adults. STUDY DESIGN AND METHODS: This study was an updated systematic review with meta-analysis and Trial Sequential Analysis (TSA) of randomized clinical trials. A clear differentiation (separation) was made between a higher (liberal) oxygenation and a lower (conservative) oxygenation strategy and their effects on all-cause mortality, serious adverse events, quality of life, lung injury, sepsis, and cardiovascular events at time points closest to 90 days in acutely ill adults. RESULTS: The study included 50 randomized clinical trials of 21,014 participants; 36 trials with a total of 20,166 participants contributed data to the analyses. Meta-analysis and TSAs showed no difference between higher and lower oxygenation strategies in trials at overall low risk of bias except for blinding: mortality relative risk (RR), 0.98 (95% CI, 0.89-1.09; TSA-adjusted CI, 0.86-1.12; low certainty evidence); serious adverse events RR, 0.99 (95% CI, 0.89-1.12; TSA-adjusted CI, 0.83-1.19; low certainty evidence). The corresponding summary estimates including trials with overall low and high risk of bias showed similar results. No difference was found between higher and lower oxygenation strategies in meta-analyses and TSAs regarding quality of life, lung injury, sepsis, and cardiovascular events (very low certainty evidence). INTERPRETATION: No evidence was found of beneficial or harmful effects of higher vs lower oxygenation strategies in acutely ill adults (low to very low certainty evidence).

RESUMO

BACKGROUND: There is now a rising commitment to acknowledge the role patients and families play in contributing to their safety. This review focuses on one type of involvement in safety - patient and family involvement in escalation of care for serious life-threatening conditions i.e. helping secure a step-up to urgent or emergency care - which has been receiving increasing policy and practice attention. This review was concerned with the negotiation work that patient and family members undertake across the emergency care escalation pathway, once contact has been made with healthcare staff. It includes interventions aiming to improve detection of symptoms, communication of concerns and staff response to these concerns. OBJECTIVES: To assess the effects of interventions designed to increase patient and family involvement in escalation of care for acute life-threatening illness on patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP) ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform from 1 Jan 2000 to 24 August 2018. The search was updated on 21 October 2019. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cluster-randomised controlled trials where the intervention focused on patients and families working with healthcare professionals to ensure care received for acute deterioration was timely and appropriate. A key criterion was to include an interactive element of rehearsal, role play, modelling, shared language, group work etc. to the intervention to help patients and families have agency in the process of escalation of care. The interventions included components such as enabling patients and families to detect changes in patients' conditions and to speak up about these changes to staff. We also included studies where the intervention included a component targeted at enabling staff response. DATA COLLECTION AND ANALYSIS: Seven of the eight authors were involved in screening; two review authors independently extracted data and assessed the risk of bias of included studies, with any disagreements resolved by discussion to reach consensus. Primary outcomes included patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. Our advisory group (four users and four providers) ensured that the review was of relevance and could inform policy and practice. MAIN RESULTS: We included nine studies involving 436,684 patients and family members and one ongoing study. The published studies focused on patients with specific conditions such as coronary artery disease, ischaemic stroke, and asthma, as well as pregnant women, inpatients on medical surgical wards, older adults and high-risk patients with a history of poor self-management. While all studies tested interventions versus usual care, for four studies the usual care group also received educational or information strategies. Seven of the interventions involved face-to-face, interactional education/coaching sessions aimed at patients/families while two provided multi-component education programmes which included components targeted at staff as well as patients/families. All of the interventions included: (1) an educational component about the acute condition and preparedness for future events such as stroke or change in fetal movements: (2) an engagement element (self-monitoring, action plans); while two additionally focused on shared language or communication skills. We had concerns about risk of bias for all but one of the included studies in respect of one or more criteria, particularly regarding blinding of participants and personnel. Our confidence in results regarding the effectiveness of interventions was moderate to low. Low-certainty evidence suggests that there may be moderate improvement in patients' knowledge of acute life-threatening conditions, danger signs, appropriate care-seeking responses, and preparedness capacity between interactional patient-facing interventions and multi-component programmes and usual care at 12 months (MD 4.20, 95% CI 2.44 to 5.97, 2 studies, 687 participants). Four studies in total assessed knowledge (3,086 participants) but we were unable to include two other studies in the pooled analysis due to differences in the way outcome measures were reported. One found no improvement in knowledge but higher symptom preparedness at 12 months. The other study found an improvement in patients' knowledge about symptoms and appropriate care-seeking responses in the intervention group at 18 months compared with usual care. Low-certainty evidence from two studies, each using a different measure, meant that we were unable to determine the effects of patient-based interventions on self-efficacy. Self-efficacy was higher in the intervention group in one study but there was no difference in the other compared with usual care. We are uncertain whether interactional patient-facing and multi-component programmes improve time from the start of patient symptoms to treatment due to low-certainty evidence for this outcome. We were unable to combine the data due to differences in outcome measures. Three studies found that arrival times or prehospital delay time was no different between groups. One found that delay time was shorter in the intervention group. Moderate-certainty evidence suggests that multi-component interventions probably have little or no impact on mortality rates. Only one study on a pregnant population was eligible for inclusion in the review, which found no difference between groups in rates of stillbirth. In terms of unintended events, we found that interactional patient-facing interventions to increase patient and family involvement in escalation of care probably have few adverse effects on patient's anxiety levels (moderate-certainty evidence). None of the studies measured or reported patient and family perceptions of involvement in escalation of care or patient and family experience of patient care. Reported outcomes related to healthcare professionals were also not reported in any studies. AUTHORS' CONCLUSIONS: Our review identified that interactional patient-facing interventions and multi-component programmes (including staff) to increase patient and family involvement in escalation of care for acute life-threatening illness may improve patient and family knowledge about danger signs and care-seeking responses, and probably have few adverse effects on patient's anxiety levels when compared to usual care. Multi-component interventions probably have little impact on mortality rates. Further high-quality trials are required using multi-component interventions and a focus on relational elements of care. Cognitive and behavioural outcomes should be included at patient and staff level.

RESUMO

OBJECTIVES: Most patients requiring mechanical ventilation only require it for a short term (< 4 d of mechanical ventilation). Those undergoing prolonged acute mechanical ventilation (≥ 4 d mechanical ventilation) represent a select cohort who face significant morbidity, mortality, and resource utilization. Using administrative codes, we identified prolonged acute mechanical ventilation and short-term mechanical ventilation patients and compared their baseline characteristics, hospital events, and hospital outcomes. DESIGN: Retrospective cohort. SETTING: Seven-hundred eighty-seven acute care hospitals, United States, contributing data to Premier database, 2014-2018. PATIENTS: Patients on mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among 691,961 patients meeting the enrollment criteria, 266,374 (38.5%) received prolonged acute mechanical ventilation. At baseline, patients on prolonged acute mechanical ventilation were similar to short-term mechanical ventilation in age (years: 62.0 ± 15.8 prolonged acute mechanical ventilation vs 61.7 ± 17.2 short-term mechanical ventilation), gender (males: 55.6% prolonged acute mechanical ventilation vs 53.9% short-term mechanical ventilation), and race (white: 69.1% prolonged acute mechanical ventilation vs 72.4% short-term mechanical ventilation). The prolonged acute mechanical ventilation group had a higher comorbidity burden than short-term mechanical ventilation (mean Charlson Score 3.5 ± 2.7 vs 3.1 ± 2.7). The prevalence of vasopressors (50.3% vs 36.9%), dialysis (19.4% vs 10.3%), severe sepsis (20.3% vs 10.3%), and septic shock (33.5% vs 15.9%) was higher in prolonged acute mechanical ventilation than short-term mechanical ventilation. Hospital mortality (29.75% vs 21.1%), combined mortality, or discharge to hospice (37.2% vs 25.3%), extubation failure (12.3% vs 6.1%), tracheostomy (21.6% vs 4.5%), development of Clostridium difficile (4.5% vs 1.7%), and incidence density of ventilator-associated pneumonia (2.4/1,000 patient-days vs 0.6/1,000 patient-days) were all higher in the setting of prolonged acute mechanical ventilation than short-term mechanical ventilation. Median (interquartile range) post mechanical ventilation onset length of stay (13 [8-20] vs 4 d [1-8 d]) and hospital costs ($55,014 [$35,051-$88,007] vs $20,120 [$12,071-$34,915] were higher in prolonged acute mechanical ventilation than short-term mechanical ventilation. CONCLUSIONS: Over one-third of all hospitalized patients on mechanical ventilation require it for greater than or equal to 4 days. Prolonged acute mechanical ventilation patients exhibit a higher burden of both chronic and acute illness and experience higher rates than those on short-term mechanical ventilation of hospital-acquired complications and worse clinical and economic outcomes.

RESUMO

OBJECTIVE: We aimed to evaluate the effects of combining the Simplified-Acute-Physiology-Score (SAPS) 2 or the SAPS 3 with Interleukin-6 (IL-6) or Procalcitonin (PCT) or C-Reactive Protein (CRP) concentrations for predicting in-hospital mortality. MATERIAL AND METHODS: This retrospective study was conducted in an interdisciplinary 22-bed intensive care unit (ICU) at a German university hospital. Within an 18-month period, SAPS 2 and SAPS 3 were calculated for 514 critically ill patients that were admitted to the internal medicine department. To evaluate discrimination performance, the area under the receiver operating characteristic curves (AUROCs) and the 95% confidence intervals (95% CIs) were calculated for each score, exclusively or in combination with IL-6 or PCT or CRP. DeLong test was used to compare different AUROCs. RESULTS: The SAPS 2 exhibited a better discrimination performance than SAPS 3 with AUROCs of 0.81 (95% CI, 0.76-0.86) and 0.72 (95% CI, 0.66-0.78), respectively. Overall, combination of the SAPS 2 with IL-6 showed the best discrimination performance (AUROC 0.82; 95% CI, 0.77-0.87), albeit not significantly different from SAPS2. IL-6 performed better than PCT and CRP with AUROCs of 0.75 (95% CI, 0.69-0.81), 0.72 (95% CI, 0.66-0.77) and 0.65 (95% CI, 0.59-0.72), respectively. Performance of the SAPS 3 improved significantly when combined with IL-6 (AUROC 0.76; 95% CI, 0.69-0.81) or PCT (AUROC 0.73; 95% CI, 0.67-0.78). CONCLUSIONS: Our analysis provided evidence that the risk stratification performance of the SAPS 3 and, to a lesser degree, also of the SAPS 2 can increase when combined with IL-6. A more accurate detection of aberrant or dysregulated systemic immunological responses (by IL-6) may explain the higher performance achieved by SAPS 3 + IL-6 vs. SAPS 3. Thus, implementation of IL-6 in critical care scores can improve prediction outcomes, especially in patients experiencing acute inflammatory conditions; however, statistical results may vary across hospital types and/or patient populations with different case mix.

RESUMO

BACKGROUND: Non-variceal acute UGI bleeding (NV-AUGIB) is a frequent indication for transfusion, but the best hemoglobin threshold and target values for transfusion in relation to the patients' performance status are unknown. OBJECTIVE: To identify threshold and target hemoglobin levels for transfusion favoring survival of patients with NV-AUGIB stratified by ASA score. DESIGN: Prospective cohort study. SETTING: 50 hospitals of the Italian National Health Service. PARTICIPANTS: 2758 consecutive patients with NV-AUGIB admitted to 50 Italian hospitals from January 1st, 2014 to December 31st, 2015. Five hemoglobin cut-off values were evaluated. RESULTS: 30-days mortality: overall: 5.4%; ASA 1-2 patients: 2.5%; ASA 3-4 patients: 10.8%. Mortality was higher when hemoglobin at admission was ≤ 7 g/dL in ASA 1-2 patients, and when it was ≤ 8 g/dL in ASA 3-4 patients. The hemoglobin levels after transfusion favouring survival were ≥ 8 g/dL in ASA 1-2, p <0.0001 and 9-10 g/dL in ASA 3-4 patients; p = 0.0002. CONCLUSIONS: In patients with NV-AUGIB the physical performance status should dictate the transfusion strategy. In ASA 1-2 patients, admission hemoglobin values ≤ 7 g/dL should prompt transfusion, aiming at a target value of 8-9 g/dL; the corresponding figures for ASA 3-4 patients are: admission hemoglobin level ≤ 8 g/dL and target value of 9-10 g/dL.

RESUMO

OBJECTIVE: To analyze morbidity and factors affecting mortality in emergency abdominal surgery in the Russian Federation. MATERIAL AND METHODS: The study included patients with acute abdominal diseases aged 18 years and older. All patients were hospitalized in emergency surgical care departments of 3.194 state healthcare institutions in 84 regions of the Russian Federation in 2018. Morbidity, surgical activity and mortality were analyzed. RESULTS: There were 680.337 cases of hospitalization in emergency surgical department, morbidity rate was 582 cases per 100 000. The most common emergency surgical diseases were acute appendicitis (142.3 cases per 100 000), acute cholecystitis (139.0 cases per 100 000) and acute pancreatitis (131.2 cases per 100 000). Surgery was performed in 399.051 (58.7%) patients. In-hospital mortality rate was 2.4% (16 051 cases). CONCLUSION: There are certain factors affecting mortality rate in acute abdominal diseases. The leading problems in organizing emergency surgical care in Russia are insufficient equipment of rural and small municipal surgical hospitals, different staffing with surgeons in rural areas and large cities and late hospitalization of patients.

RESUMO

INTRODUCTION: Guidelines recommend early endoscopic retrograde cholangiopancreatography for the management of acute cholangitis, but the definition of the term "early" remains debatable. This study analyzed national trends in the timing of endoscopic retrograde cholangiopancreatography and identified the ideal time to perform preoperative endoscopic retrograde cholangiopancreatography in patients with acute cholangitis. METHODS: The 2005 to 2016 National Inpatient Sample was used to identify patients undergoing cholecystectomy for acute cholangitis. Severity of cholangitis was defined using the 2013 Tokyo Grading Criteria, where Tokyo grade III patients were defined as having organ dysfunction and non-Tokyo grade III patients were defined as grades I and II. Multivariable regressions (accounting for patient and hospital characteristics) were used to identify the timing of preoperative endoscopic retrograde cholangiopancreatography associated with the least mortality risk. RESULTS: Of 91,051 patients undergoing cholecystectomy for cholangitis, 55% underwent preoperative endoscopic retrograde cholangiopancreatography: 24% of patients received endoscopic retrograde cholangiopancreatography on the day of admission, 41% on hospital day 2, and the use of endoscopic retrograde cholangiopancreatography decreased gradually thereafter. Mortality rates remained under 1% if endoscopic retrograde cholangiopancreatography was performed during the first 3 days and increased as endoscopic retrograde cholangiopancreatography was performed during days 4 to 7 (P < .001). On multivariable regression, endoscopic retrograde cholangiopancreatography performed >72 hours after admission was associated with increased mortality (adjusted odds ratio 1.80, P = .01). Receiving endoscopic retrograde cholangiopancreatography P > 72 hours increased risk of death among Tokyo grade III patients (adjusted odds ratio 1.88, P = .01). Overall, during the study period, the utilization of preoperative endoscopic retrograde cholangiopancreatography for all grades of acute cholangitis increased from 39% of patients in 2005 to 51% in 2016 (P < .001). CONCLUSION: There has been an increase in the use of endoscopic retrograde cholangiopancreatography for acute cholangitis. Although endoscopic retrograde cholangiopancreatography on the day of admission was not associated with a decrease in mortality in patients with Tokyo grade III disease, endoscopic retrograde cholangiopancreatography within 72 hours of hospitalization was associated with decreased in-hospital mortality.

RESUMO

OBJETIVOS: Diseñar y validar un modelo predictivo de mortalidad hospitalaria precoz (≤ 48 horas) en pacientes $ 65 años y basado en variables determinadas a nivel prehospitalario. MÉTODO: Estudio multicéntrico de cohorte prospectivo y observacional. Se incluyeron pacientes $ 65 años atendi¬dos por unidades de soporte vital avanzado y trasladados a un servicio de urgencias hospitalario. Se recogieron va-riables demográficas, clínicas y analíticas. Se construyó y validó una escala de puntuación mediante la categoriza¬ción de las variables seleccionadas mediante regresión logística en función de la mortalidad en ≤ 48 horas. RESULTADOS: Se reclutaron 1.759 pacientes, la edad mediana fue de 79 años (RIC 72-85), 766 eran mujeres (43,5%), y fallecieron 108 pacientes (6,1%) en ≤ 48 horas. El modelo predictivo -escala POAWS (Prehospital Older Adults Warning Score)- incluyó la edad, presión arterial sistólica, temperatura, saturación de oxígeno en relación con la frac¬ción inspirada de oxígeno, escala de coma de Glasgow y ácido láctico en sangre venosa. El área bajo la curva de la característica operativa del receptor para la mortalidad en ≤ 48 horas fue de 0,853 (IC 95%: 0,80-0,91; p < 0,001). La mortalidad en los pacientes de alto riesgo (> 7 puntos en la escala) fue del 69%. CONCLUSIONES: La escala POAWS desarrollada en el presente estudio puede ser de utilidad para estratificar el riesgo de muerte de los patientes de 65 o más años durante las 48 horas siguientes a la atención en el ámbito prehospitalario


OBJECTIVE: To develop and validate a prehospital risk model to predict early in-hospital mortality (󖽀 hours) in patients aged 65 years or older. METHODS: Prospective multicenter observational study in a cohort of patients aged 65 years or older attended by advanced life support emergency services and transferred to 5 Spanish hospitals between April 2018 and July 2019. We collected demographic, clinical and laboratory variables. A risk score was constructed and validated based on the analysis of prehospital variables associated with death within 48 hours. Predictors were selected by logistic regression. RESULTS: A total of 1759 patients were recruited. The median age was 79 years (interquartile range, 72-85 years), and 766 (43.5%) were women. One hundred eight patients (6.1%) died within 48 hours. Predictors in the Prehospital Older Adults Warning Scale (POAWS) were age, systolic blood pressure, temperature, the ratio of oxygen saturation to the fraction of inspired oxygen, score on the Glasgow coma scale, and lactic acid concentration in venous blood. The area under the receiver operating characteristic curve of the model to predict early mortality was 0.853 (95% CI, 0.80-0.91; P < .001). Mortality in patients at high risk (POAWS score, > 7) was 69%. CONCLUSIONS: The prehospital POAWS score can be used to stratify risk for death within 48 hours in patients aged 65 years or older
