No Association of Blood Alcohol Concentration on Burn Patient Outcomes

IntroductionAlcohol abuse is common among burn patients. Burn patients under the influence of alcohol are at risk for developing organ failure, prolonged hospital duration, and increased intensive care unit (ICU) resources. Our study aims to analyze the association between presenting alcohol levels and the outcomes of burn patients. MethodsA retrospective analysis of admitted burn patients was performed from 2016 to 2021. Patients were divided into two groups based on blood alcohol content (BAC), low (<80), and high (≥80) mg/dL. Data included demographics, comorbidities, and outcomes. Univariate analyses were performed, and a P value <0.05 was significant. ResultsA total of 197 patients were included (32.5% females, mean age 47.2 ± 15.2, 26.9% smokers, 28.4% illegal drug abuse, and 56.3% no comorbidities). Mortality was 7.6%, morbidity 20.8%, 39.1% required burn ICU admission, and 25.9% were intubated. When comparing BAC groups, we found no differences in demographics, comorbidities, inhalational injury incidence, carbon monoxide level, intubation, or burn ICU admission rates. The high-BAC group had longer ventilator days (high BAC 16.7 ± 19.3 versus low BAC 7.5 ± 9.1, P = 0.026) and longer stays in the ICU (18.6 ± 21.8 versus 10.7 ± 15.4, P = 0.075). The low-BAC group had more 3rd-degree burn percentage (5.0 ± 15.3 versus 15.4 ± 27.5, P = 0.024). Both morbidity and in-house mortality rates were similar for both groups (23.8% versus 16.0%, P = 0.192, and 6.6% versus 9.3%, P = 0.476, respectively). ConclusionsBurn patients with higher BAC had significantly longer mechanical ventilator days. However, higher alcohol concentrations had no association with regard to mortality, overall length of stay, or complication rates.

Comparison of Pneumonia-specific Scores, Sepsis Score and Generic Score in Predicting the Severity of Community-acquired Pneumonia: A Cross-sectional Study

Introduction: Pneumonia is defined as inflammation of the pulmonary parenchyma caused by an infectious agent. Community-acquired Pneumonia (CAP) is a heterogeneous disease with a significant disease burden, morbidity, and mortality. Severe Community-acquired Pneumonia (SCAP) has been proven to be associated with increased Intensive Care Unit (ICU) admission, mechanical ventilation, and mortality. Although several severity assessment tools are available, there is a lack of evidence to support one tool over another in patients with pneumonia. Aim: To compare the ability of pneumonia-specific scores {{Confusion, Urea, Respiratory rate, Blood pressure (CURB)- 65 and Expanded CURB-65)}, Sepsis score {quick Sepsisrelated Organ Failure Assessment (qSOFA)}, and Generic score {National Early Warning Score (NEWS)} in predicting SCAP patients at the time of hospital admission. Materials and Methods: This was a hospital-based crosssectional study conducted in the Department of Pulmonary Medicine, Government Hospital for Chest and Communicable Diseases, Andhra Medical College, Visakhapatnam, India, on 100 patients with clinically and radiologically diagnosed CAP over a period of six months from April 2023 to September 2023 after obtaining Institutional ethics clearance and informed consent. All four severity scores (CURB-65, eCURB-65, qSOFA, NEWS) were documented in each patient at the time of admission. Outcomes such as 30-day mortality and ICU admission were measured. Receiver Operating Characteristic (ROC) curve analysis was performed for mortality prediction and ICU admission for all four scoring systems, and statistical analysis was carried out using Statistical Packages for Social Sciences (SPSS) version 24.0. Results: Out of 100 patients, 62 (62%) were males, and the remaining 38 (38%) were females with a mean age of 56±15 years. The number of patients with co-morbidities was 48 (48%). Regarding addictive habits, smoking and alcohol played a significant role at 38% and 33%, respectively. A 30- day mortality was observed in 18 (18%) patients, and 20 (20%) patients received ICU treatment. The frequency of patients with co-morbidities such as Diabetes Mellitus (DM), Hypertension (HTN), Ischaemic Heart Disease (IHD), and Chronic Obstructive Pulmonary Disease (COPD) was 21%, 33%, 5%, and 3%, respectively. For ICU admission as an outcome measure, the Area Under Receiver Operating Characteristics (AUROC) values were as follows: CURB-65: 0.977 (95% CI: 0.949-1.00, p-value &lt;0.001); Expanded CURB-65: 0.966 (95% CI: 0.931-1.00, p-value &lt;0.001); qSOFA: 0.935 (95% CI: 0.881-0.989, p-value &lt;0.001); NEWS score: 0.967 (95% CI: 0.934-1.00, p-value &lt;0.001). Conclusion: In the present study, all four scoring systems were equally effective in detecting the need for ICU admission and predicting 30-day mortality among CAP patients at the time of admission. However, organ-specific tools (CURB-65 (2-3) moderate) have demonstrated valid and effective means of assessing severity compared to sepsis scores and generic tools.

Association between energy surplus and intensive care unit length of stay in critically ill patients: A retrospective cohort study.

Patients experiencing persistent critical illness have poor short-term and long-term outcomes and consume disproportionate amounts of health care resources. Nutrition optimization may improve outcomes, though few data exist on resting energy expenditure and nutrition requirements. We hypothesized that increased energy surplus per day is associated with increased intensive care unit (ICU) length of stay (LoS) in critically ill patients. Patients from a single ICU at Royal London Hospital were included in this retrospective cohort study. energy surplus measured by serial indirect calorimetry (IC) and nutrition intake. mechanical ventilation of ≥3 days and expected to remain ventilated. ICU LoS. Across 30 patients (median LoS 21 days), increased ICU LoS was associated with actual daily energy intake surplus to resting energy expenditure (REE) (R2 0.16; P < 0.005). Median REE was less than predicted energy requirements: 24 kcal per day per kilogram of ideal body weight (IBW) (interquartile range [IQR], 20-28) vs 28 kcal/day/kg IBW (IQR, 26-29) (P < 0.001). Patients with COVID-19 had a median energy surplus (actual intake- REE) + 344 kcal/day (IQR 35-517) vs -57 kcal/day (IQR -324 to 211) in other patients (P = 0.011); however, they had a median LoS of 44 days (IQR 26-58) vs 10 days (IQR 7-24), respectively (P < 0.001). Patients with obesity had a median energy deficit of -32 kcal/day (IQR -384 to 335) vs +234 kcal/day (IQR -79 to 499) for nonobese patients (P = 0.021). Overfeeding represents an easily modifiable factor to improve outcomes in patients experiencing persistent critical illness, for which IC may be useful.

Mechanical insufflation-exsufflation to promote extubation success in critically ill adults on intensive care: protocol for a randomised controlled feasibility trial

BackgroundExtubation failure, defined as reintubation within 48 h, is associated with increased intensive care unit (ICU) length of stay and higher mortality risk. One cause of extubation failure is secretion retention, resulting from an inability to cough effectively. Mechanical insufflation-exsufflation (MI-E) simulates a cough aiding secretion clearance. However, MI-E is not routinely used in the ICU for invasively ventilated patients. This study aims to determine feasibility and acceptability of a randomised controlled trial (RCT) examining MI-E use to promote extubation success in intubated, ventilated adults.MethodsIt is a single-centre, feasibility RCT with semi-structured interviews, economic scoping, and exploratory physiology study.The feasibility RCT (n = 50) will compare standard care to a MI-E protocol including a minimum of two MI-E sessions via the endotracheal tube prior to extubation. Post-extubation, MI-E will be delivered via facemask or mouthpiece up to two times/day for 48 h. MI-E settings will be individualised. All patients will receive standard care (no MI-E) in relation to mechanical ventilation, weaning, rehabilitation, physiotherapy techniques such as positioning, manual airway clearance techniques, manual/ventilator hyperinflation, endotracheal suctioning, and nebulisation. Clinical data collection will occur before, on completion, and 5-min post-physiotherapy sessions (intervention/control arms). Resource use will be calculated for each 24-h period. Analyses will be descriptive and address feasibility outcomes including participant recruitment and attrition, proportion of MI-E treatment sessions completed, dataset completeness, and frequency of adverse events and acceptability.Semi-structured online interviews informed by the Theoretical Framework of Acceptability (TFA) with patients, clinicians, and family members will explore the acceptability of the MI-E intervention and study processes.Interview data will be analysed using reflexive thematic analysis based on TFA domains through first-level coding.The embedded physiology study will use electrical impedance tomography and lung ultrasound to explore lung recruitment and de-recruitment during MI-E in a subset of 5–10 patients.DiscussionThis study will examine feasibility and acceptability of a RCT protocol of MI-E to promote extubation success. Study findings will inform design modification and conduct of a future adequately powered trial. Furthermore, the study will contribute and advance the understanding of MI-E use in critically ill intubated adults.Trial registrationISRCTN 24603037; IRAS 303674

Diabetic Ketoacidosis in Cardiac Surgery Patients at Fiona Stanley Hospital 2015 to 2018

This study aimed to examine whether the development of perioperative diabetic ketoacidosis (DKA) increased intensive care unit (ICU) length of stay (LOS) and postoperative hospital LOS.

Aerosolized Antibiotics to Manage Ventilator-Associated Infections: A Comprehensive Review.

Ventilator-associated lower respiratory tract infectious complications in critically ill patients cover a wide spectrum of one disease process (respiratory infection), initiating from tracheal tube and/or tracheobronchial colonization, to ventilator associated tracheobronchitis (VAT) and ventilator-associated pneumonia (VAP). VAP occurence has been associated with increased intensive care unit (ICU) morbidity (ventilator days, as well as length of ICU and hospital stay) and ICU mortality. Therefore, treatments that aim at VAP/VAT incidence reduction are a high priority. The aim of the present review is to discuss the current literature concerning two major aspects: (a) can aerosolized antibiotics (AA) administered in a pre-emptive way prevent the occurrence of ventilator-associated infections? and (b) can VAT treatment with aerosolized avert the potential evolution to VAP? There were identified eight studies that provided data on the use of aerosolized antibiotics for the prevention of VAT/VAP. Most of them report favorable data on reducing the colonisation rate and the progression to VAP/VAT. Another four studies dealt with the treatment of VAT/VAP. The results support the decrease in the incidence to VAP transition and/or the improvement in signs and symptoms of VAP. Moreover, there are concise reports on higher cure rates and microbiological eradication in patients treated with aerosolized antibiotics. Yet, differences in the delivery modality adopted and resistance emergence issues preclude the generalisability of the results. Aerosolized antibiotic therapy can be used to manage ventilator-associated infections, especially those with difficult to treat resistance. The limited clinical data raise the need for large randomized controlled trials to confirm the benefits of AA and to evaluate the impact on antibiotic selection pressure.

Association between obstructive sleep apnea and atrial fibrillation and delirium after cardiac surgery. Sub-analysis of DECADE trial

BackgroundAtrial fibrillation and delirium are common complications after cardiac surgery. Both are associated with increased Intensive Care Unit (ICU) and hospital length of stay, functional decline, 30-day mortality and increase in health care costs. Obstructive Sleep Apnea (OSA) induces deleterious effects in the cardiovascular and nervous systems. We hypothesized that adult patients with preoperative OSA have a higher incidence of postoperative atrial fibrillation and delirium than patients without OSA, after cardiac surgery. MethodsSub-analysis of the DECADE trial at Cleveland Clinic hospitals. Our exposure was OSA, defined by STOP-BANG questionnaire score higher than 5 and/or a preoperative diagnosis of OSA. The primary outcome was atrial fibrillation, defined by clinician diagnosis or documented arrhythmia. The secondary outcome was delirium assessed twice during the initial five postoperative days using the Confusion Assessment Method for ICU. We assessed the association between OSA, and atrial fibrillation and delirium using a logistic regression model adjusted for confounders using inverse probability of treatment weighting. Results590 patients were included in the final analysis. 133 were diagnosed with OSA and 457 had no OSA. Satisfactory balance between groups for most confounders (absolute standardized difference < 0.10) was achieved after weighting. The atrial fibrillation incidence was 37% (n = 49) in the patients with OSA and 33% (n = 150) in the non-OSA patients. OSA was not associated with atrial fibrillation with an estimated odds ratio of 1.22 (95% CI: 0.75,1.99;p = 0.416). The delirium incidence was 17% (n = 22) in patients with OSA and 15% (n = 67) in the non-OSA patients. OSA was not associated with delirium with an estimated odds ratio of 0.93 (95% CI: 0.51,1.69;p = 0.800). ConclusionIn adult patients having cardiac surgery, OSA is not associated with a higher incidence of postoperative atrial fibrillation and delirium. These results suggest different prominent factors rather than OSA affect the incidence of these postoperative outcomes.

Frailty in middle cranial fossa approach for encephalocele or cerebrospinal fluid leak repair.

The modified 5-item frailty index (mFI-5) is a concise, comorbidity-based risk stratification tool that can predict adverse outcomes after surgery. The goal of this study was to understand the frailty of patients undergoing surgery for temporal encephalocele or cerebrospinal fluid (CSF) leak and the utility of mFI-5 for predicting increased post-operative outcomes. A retrospective review of adults with temporal encephalocele or CSF leak who underwent middle cranial fossa (MCF) approach craniotomies with or without mastoidectomy from January 2015 through August 2021 at a tertiary care academic medical center was performed. Patients who underwent additional surgeries or extended surgical approaches were excluded. The mFI-5 was calculated for all patients. Demographic and clinical data were obtained from the medical record. Thirty-six patients underwent 40 MCF approach craniotomies for temporal encephalocele or CSF leak, including three revision cases and one patient with sequential bilateral operations. Mean age was 54.1 ± 10.8 years, and 66.7% were female. In the univariable regression analysis, mFI-5 score, age, and procedure time use were significantly associated with increased hospital length of stay (LOS) but not increased intensive care unit (ICU) LOS. Anesthesia time and lumbar drain were significantly associated with increased hospital LOS and ICU LOS, and they remained significantly associated with increased hospital LOS in the multivariable model. Frailty is associated with increased hospital LOS stay among patients undergoing MCF approach for CSF leak or encephalocele. Reducing anesthesia time and avoiding lumbar drain use are potentially modifiable risk factors that can reduce the LOS and associated costs. 4.

Measurement of Procalcitonin as an Indicator of Severity in Patients With Chronic Obstructive Pulmonary Disease Admitted With Respiratory Illness.

IntroductionExacerbations of chronic obstructive pulmonary disease (COPD) are a frequent reason for hospital admission and a major cause of morbidity and mortality. A useful biomarker or indicator of disease severity at the time of presentation could help guide treatment and identify those with poor prognosis who need early aggressive intervention. We hypothesized that patients who present to the hospital with COPD exacerbations who are found to have elevated procalcitonin (PCT) levels will have worse outcomes such as longer admissions, increased intensive care unit (ICU) utilization, and more frequent readmissions than those with normal levels, regardless of presence or absence of infiltrate on initial chest X-ray (CXR).MethodsWe conducted a retrospective chart review of patients admitted to our facility with a respiratory complaint and a diagnosis of COPD to examine the relation between PCT and disease severity. A total of 156 unique encounters were reviewed, with 87 included in the final data set. Data was collected on baseline medical conditions as well as clinical status at the time of presentation. Primary endpoints included the need for overnight ICU admission, hospital length of stay greater than seven days, and repeat visit within 30 days of discharge. Secondary endpoints included the need for intubation at the time of admission, in-hospital mortality or discharge to hospice, and ICU length of stay.ResultsPatients with elevated PCT levels (>0.25ng/mL) had a significantly increased likelihood of a need for ICU admission (odds ratio 3.18) and hospital length of stay greater than seven days (odds ratio 3.38). There was no statistically significant difference in the Emergency Department readmission rate or any of the secondary outcomes.ConclusionsOur data suggests that PCT may be a useful early biomarker for patients with COPD presenting with an acute respiratory illness.

Language function in the acute phase following non-traumatic subarachnoid haemorrhage: A prospective cohort study

BackgroundAphasia is common following stroke, with associated negative impacts on quality of life and psychosocial functioning. However, the language function of individuals who develop non-traumatic subarachnoid haemorrhage (SAH) has been minimally investigated from a speech-language pathology (SLP) perspective. AimsTo examine and characterise the language function of individuals following non-traumatic SAH in the acute phase and describe the clinical profile and outcomes of individuals in this cohort with language impairment. Methods & ProceduresProspective cohort study of adults admitted to a tertiary hospital with primary non-traumatic SAH over a 12-month period (June 2018 to June 2019). Language assessment using the Brisbane Evidence-Based Language Test (EBLT) was performed within 72 h of medical stability. Assessment scores were analysed for 43 participants. Outcomes & ResultsLanguage impairment was present in 18.6% (n = 8/43) of the cohort, and was associated with increased intensive care unit (ICU) length of stay (LOS) (p < 0.01) and increased hospital length of stay (p = 0.01). The profile of participants with impaired language was highly variable with difficulties across auditory comprehension, verbal expression, reading comprehension, and written expression. Associated cognitive and attention difficulties also impacted test performance in this cohort. Six of the eight participants with impaired language required ongoing SLP support beyond hospital discharge. Conclusions & ImplicationsEarly, routine assessment of language function of individuals following non-traumatic SAH is essential and should be incorporated into clinical care pathways.

Postpartum Hemorrhage Requiring Transfusion and Risk of Cardiovascular Disease Later in Life: A Retrospective Cohort Study

(BJOG. 2021;128:738–744. doi: 10.1111/1471-0528.16515) Roughly 20% of worldwide maternal deaths are due to postpartum hemorrhage (PPH). Currently occurring in 6% to 11% of births worldwide, the incidence of PPH is on the rise. PPH severely impacts maternal mortality and morbidity rates, leading to outcomes such as increased intensive care unit (ICU) admission, increased risk of stroke, and increased risk for heart disease. Most current research identifies risks immediately following childbirth or during the puerperium while long-term risks are relatively unstudied. This study aimed to identify whether PPH is associated with long-term cardiovascular disease (CVD) such as cerebrovascular disease (CV) and ischemic heart disease (IHD).

Abstract 13806: In-Hospital Outcomes Among Patients With Septic Shock and Underlying Chronic Atrial Fibrillation

Introduction: Atrial fibrillation (AF) is the leading cause of arrhythmia among hospitalized patients. Altered hemodynamics with new-onset non-valvular atrial fibrillation, especially during sepsis/septic shock, causes decreased organ perfusion, lowers cardiac output, and increases the risk of organ dysfunction leading to increased intensive care unit (ICU) length of stay and mortality. However, little is known about the outcomes of patients hospitalized with septic shock and underlying chronic atrial fibrillation (UCAF). Hypothesis: Does UCAF increase in-hospital mortality in patients who have a diagnosis of septic shock during hospitalization. Methods: This was a retrospective analysis of the 2016 and 2017 Nationwide Readmission Database. ICD-10 codes were used to identify patients with septic shock, and these patients were stratified into those with and without a UCAF. Propensity matching analyses were performed to compare in-hospital mortality and clinical cardiovascular outcomes between the two groups. Results: A total of 353,422 patients with hospitalization for septic shock were identified, 5.8% of whom (n=20,772) had UCAF. After 2:1 propensity matching, 41,438 patients were identified as having septic shock without UCAF, and 20,719 patients were identified as having septic shock with UCAF. In hospital mortality [34.4% vs. 34.1%, p= 0.049], incidence of ischemic stroke [2.5% vs. 2.2%, p = 0.012], acute heart failure [1.8% vs. 1.4%, p &lt; 0.001], length of stay [11.46 days vs. 10.93 days, p&lt; 0.001], mean total charges [$150 4094 vs. $140 4037, p &lt; 0.001] were significantly higher in patients with septic shock and UCAF compared to patients with septic shock without UCAF. Conclusions: The study identified UCAF as an adverse prognosticator for inpatient mortality and severe cardiovascular clinical outcomes. The study suggests the need for future research to improve patient outcomes of patients with septic shock and UCAF.

Intraoperative and Postoperative Hemodynamic Predictors of Acute Kidney Injury in Pediatric Heart Transplant Recipients

AbstractAcute kidney injury (AKI) is common after pediatric heart transplantation (HT) and is associated with inferior patient outcomes. Hemodynamic risk factors for pediatric heart transplant recipients who experience AKI are not well described. We performed a retrospective review of 99 pediatric heart transplant patients at Lucile Packard Children's Hospital Stanford from January 1, 2015, to December 31, 2019, in which clinical and demographic characteristics, intraoperative perfusion data, and hemodynamic measurements in the first 48 postoperative hours were analyzed as risk factors for severe AKI (Kidney Disease: Improving Global Outcomes [KDIGO] stage ≥ 2). Univariate analysis was conducted using Fisher's exact test, Chi-square test, and the Wilcoxon rank-sum test, as appropriate. Multivariable analysis was conducted using logistic regression. Thirty-five patients (35%) experienced severe AKI which was associated with lower intraoperative cardiac index (p = 0.001), higher hematocrit (p &lt; 0.001), lower body temperature (p &lt; 0.001), lower renal near-infrared spectroscopy (p = 0.001), lower postoperative mean arterial blood pressure (MAP: p = 0.001), and higher central venous pressure (CVP; p &lt; 0.001). In multivariable analysis, postoperative CVP &gt;12 mm Hg (odds ratio [OR] = 4.27; 95% confidence interval [CI]: 1.48–12.3, p = 0.007) and MAP &lt;65 mm Hg (OR = 4.9; 95% CI: 1.07–22.5, p = 0.04) were associated with early severe AKI. Children with severe AKI experienced longer ventilator, intensive care, and posttransplant hospital days and inferior survival (p = 0.01). Lower MAP and higher CVP are associated with severe AKI in pediatric HT recipients. Patients, who experienced AKI, experienced increased intensive care unit (ICU) morbidity and inferior survival. These data may guide the development of perioperative renal protective management strategies to reduce AKI incidence and improve patient outcomes.

Chronic Critical Illness and PICS Nutritional Strategies.

The nutritional hallmark of chronic critical illness (CCI) after sepsis is persistent inflammation, immunosuppression, and catabolism syndrome (PICS), which results in global resistance to the anabolic effect of nutritional supplements. This ultimately leaves these patients in a downward phenotypic spiral characterized by cachexia with profound weakness, decreased capacity for rehabilitation, and immunosuppression with the propensity for sepsis recidivism. The persistent catabolism is driven by a pathologic low-grade inflammation with the inability to return to homeostasis and by ongoing increased energy expenditure. Better critical care support systems and advances in technology have led to increased intensive care unit (ICU) survival, but CCI due to PICS with poor long-term outcomes has emerged as a frequent phenotype among ICU sepsis survivors. Unfortunately, therapies to mitigate or reverse PICS-CCI are limited, and recent evidence supports that these patients fail to respond to early ICU evidence-based nutrition protocols. A lack of randomized controlled trials has limited strong recommendations for nutrition adjuncts in these patients. However, based on experience in other conditions characterized by a similar phenotype, immunonutrients aimed at counteracting inflammation, immunosuppression, and catabolism may be important for improving outcomes in PICS-CCI patients. This manuscript intends to review several immunonutrients as adjunctive therapies in treating PICS-CCI.

Postoperative delirium after cardiac surgery of elderly patients as an independent risk factor for prolonged length of stay in intensive care unit and in hospital

BackgroundPostoperative delirium (POD) is a relevant and underdiagnosed complication after cardiac surgery that is associated with increased intensive care unit (ICU) and hospital length of stay (LOS). The aim of this subgroup study was to compare the frequency of tested POD versus the coded International Statistical Classification of Diseases and Related Health Problems (ICD) diagnosis of POD and to evaluate the influence of POD on LOS in ICU and hospital.Methods254 elective cardiac surgery patients (mean age, 70.5 ± 6.4 years) at the University Hospital Bonn between September 2018 and October 2019 were evaluated. The endpoint tested POD was considered positive, if one of the tests Confusion Assessment Method for ICU (CAM-ICU) or Confusion Assessment Method (CAM), 4 'A's Test (4AT) or Delirium Observation Scale (DOS) was positive on one day.ResultsPOD occurred in 127 patients (50.0%). LOS in ICU and hospital were significantly different based on presence (ICU 165.0 ± 362.7 h; Hospital 26.5 ± 26.1 days) or absence (ICU 64.5 ± 79.4 h; Hospital 14.6 ± 6.7 days) of POD (p < 0.001). The multiple linear regression showed POD as an independent predictor for a prolonged LOS in ICU (48%; 95%CI 31–67%) and in hospital (64%; 95%CI 27–110%) (p < 0.001). The frequency of POD in the study participants that was coded with the ICD F05.0 and F05.8 by hospital staff was considerably lower than tests revealed by the study personnel.ConclusionApproximately 50% of elderly patients who underwent cardiac surgery developed POD, which is associated with an increased ICU and hospital LOS. Furthermore, POD is highly underdiagnosed in clinical routine.

The effect of a tiered provider staffing model on patient outcomes during the coronavirus disease 2019 pandemic: A single-center observational study.

Background:During the coronavirus disease 2019 (COVID-19) pandemic, our hospital experienced a large influx of critically ill patients with acute respiratory failure. In order to increase intensive care unit (ICU) surge capacity, we adopted a “tiered model” for ICU provider staffing where multiple ICUs were staffed by noncritical care providers under the direction of an intensivist. We hypothesized that ICUs staffed with a tiered model would result in similar patient outcomes as ICU staffed with a traditional intensivist model.Methods:We performed a single-center, observational study in seven ICUs at a tertiary care center. We included consecutive adults admitted to the ICU with acute respiratory distress syndrome (ARDS) due to COVID-19 infection. We collected baseline demographics, treatments, and outcomes of interest in traditionally staffed ICUs versus ICUs staffed with a tiered model. The primary outcome was inpatient mortality. All outcomes were censored at day 28.Results:We included a total of 138 patients in our study: 66 patients were admitted to traditionally staffed ICUs and 52 were admitted to tiered staffing ICUs. Baseline characteristics were similar between groups. ARDS treatments were similar in traditionally staffed ICUs versus tiered staffing model ICUs, including daily mean tidal volume (6.2 mL/kg vs. 6.2 mL/kg, P = 0.95), median daily fluid balance (159 mL vs. 92 mL, P = 0.54), and use of prone ventilation (58% vs. 65%, P = 0.45). There was no difference in inpatient mortality between groups (50% vs. 42%, P = 0.46). We also found no difference in ventilator-free, ICU-free, vasopressor-free, and dialysis-free days between groups.Conclusions:Our results suggest that patient outcomes are similar in ICUs with traditional staffing models when compared to ICUs with a tiered staffing mode during a pandemic.

Cancellation of Elective Surgery and Intensive Care Unit Capacity in New York State: A Retrospective Cohort Analysis.

BACKGROUND:In response to the coronavirus disease 2019 (COVID-19) pandemic, New York State ordered the suspension of all elective surgeries to increase intensive care unit (ICU) bed capacity. Yet the potential impact of suspending elective surgery on ICU bed capacity is unclear.METHODS:We retrospectively reviewed 5 years of New York State data on ICU usage. Descriptions of ICU utilization and mechanical ventilation were stratified by admission type (elective surgery, emergent/urgent/trauma surgery, and medical admissions) and by geographic location (New York metropolitan region versus the rest of New York State). Data are presented as absolute numbers and percentages and all adult and pediatric ICU patients were included.RESULTS:Overall, ICU admissions in New York State were seen in 10.1% of all hospitalizations (n = 1,232,986/n = 12,251,617) and remained stable over a 5-year period from 2011 to 2015. Among n = 1,232,986 ICU stays, sources of ICU admission included elective surgery (13.4%, n = 165,365), emergent/urgent admissions/trauma surgery (28.0%, n = 345,094), and medical admissions (58.6%, n = 722,527). Ventilator utilization was seen in 26.3% (n = 323,789/n = 1232,986) of all ICU patients of which 6.4% (n = 20,652), 32.8% (n = 106,186), and 60.8% (n = 196,951) was for patients from elective, emergent, and medical admissions, respectively. New York City holds the majority of ICU bed capacity (70.0%; n = 2496/n = 3566) in New York State.CONCLUSIONS:Patients undergoing elective surgery comprised a small fraction of ICU bed and mechanical ventilation use in New York State. Suspension of elective surgeries in response to the COVID-19 pandemic may thus have a minor impact on ICU capacity when compared to other sources of ICU admission such as emergent/urgent admissions/trauma surgery and medical admissions. More study is needed to better understand how best to maximize ICU capacity for pandemics requiring heavy use of critical care resources.

Staff Preparedness as an Independent Factor for Death in Patients with Severe Acute Respiratory Syndrome Admitted to an Intensive Care Unit During COVID-19 Pandemic: An Observational Cohort Study

Background: Since March 2020, WHO declared a pandemic of COVID-19 and the world is facing an unprecedented challenge. Several regions have been forced to increase intensive care unit (ICU) capacity in a short period of time to deal with an expressive number of critically ill patients. This study aims to evaluate the impact of staff preparedness by comparing the outcomes between two ICUs units from the same hospital, one previously well-established and one recently assembled to deal with a markedly increased volume of patients brought by COVID-19 pandemic.Methods: This is an observational cohort study with retrospective collection of data, conducted in Instituto de Infectologia Emílio Ribas, São Paulo-SP, Brazil. We included all patients who were admitted to an ICU with suspected COVID-19, from March 1st until April 30th, 2020. The assessed outcome was the rate of in-hospital mortality.Findings: 114 cases with severe acute respiratory syndrome were included.The median age was 57 years, with a male predominance. More than half of patients had at least one comorbidity, hypertension, diabetes or obesity. Data on respiratory pathogens were available for 112 patients, of whom 86 (77%) had a SARS-CoV-2 confirmed by polymerase chain reaction (PCR) and 4 (4%) tested positive for influenza, also by PCR method. Age > 60 years, need of invasive mechanical ventilation and an ICU type (recently assembled) were independently associated with in-hospital mortality among patients with severe acute respiratory syndrome during the COVID-19 pandemic.Interpretation: This finding highlights the importance of considering the ICU type as a possible determinant of mortality during an epidemic, together with the already well-described risk factors of age and comorbidities, suggesting that we should develop support strategies for recently assembled ICUs, as training and mentorship programs.Funding: This study has no sponsor.Declaration of Interests: The authors have nothing to disclose.Ethics Approval Statement: The National Research and Ethics Commission (CONEP) approved this study (CAAE 30632820.2.0000.0061).
