Difference In In-hospital Mortality Research Articles

Evaluation of Response to Weight-based Dosing Strategies of Continuous, Fixed-Rate Atracurium Infusions in Critically Ill, Obese Adults With Acute Respiratory Distress Syndrome.

Fixed-rate infusions of weight-based neuromuscular blocking agents (NMBAs) were adopted during the COVID pandemic to limit caregiver exposure during titrations. Although fixed-rate infusions are supported in studies of acute respiratory distress syndrome (ARDS), the optimal scalar for weight-based NMBAs in patients with obesity remains controversial. This study sought to compare change in oxygenation using two weight-based dosing strategies for atracurium in obese patients with ARDS. Secondary outcomes included total atracurium dose, mortality, and intensive care unit (ICU) and ventilator-free days. Following an institutional practice update to use ideal body weight (IBW) for patients with obesity, we retrospectively compared adults (≥18 years) with ARDS and a body mass index (BMI) ≥ 30 kg/m2 who received atracurium (15 µg/kg/min) based on actual body weight (ABW) with those using IBW. The primary outcome was change in PaO2/FiO2 ratio (P/F) 48 hours after atracurium initiation. Analysis-of-covariance compared change in P/F between groups after adjustment for confounders. The IBW group (n = 123), compared with the ABW group (n = 133), had lower baseline P/F (85.0 [71.0, 118.3] vs 93.3 [76.0, 128.3], P = 0.025) and sequential organ failure assessment (SOFA) score (9.7 ± 2.6 vs 10.5 ± 2.6, P = 0.015), with greater use of steroids (96% vs 89%, P = 0.032) and prone positioning (72% vs 58%, P = 0.015). No difference was detected in change in P/F at 48 hours (adjusted least squares mean [95% confidence interval, CI]: 55.8 [37.0, 74.5] vs 56.9 [39.6, 74.1], P = 0.90). Atracurium doses were higher in the ABW group (97.4 mg/h [84.4, 110.3] vs 55.4 [47.2, 65.7], P < 0.001). There was no difference in hospital mortality, ICU mortality, and ICU-free days or ventilator-free days. In patients with obesity with ARDS receiving fixed-rate atracurium infusions, the change in P/F at 48 hours did not differ based on weight. Atracurium dosed on IBW may use less total drug without compromising ability to improve oxygenation. This is the first study comparing the dosing weight used for continuous infusion atracurium in hospitalized, critically ill ARDS patients with obesity. Additional studies are warranted to optimize dosing in obese patients.

Early intravenous beta-blockers injection in patients with acute STEMI: the results of the Russian registry REGION-IM

Aim. To study the features of the appointment of beta-blockers (BB) therapy in the early stages of acute myocardial infarction without ST segment elevation (nonSTEMI) in real clinical practice in the Russian Federation according to the REGION registry, to analyze the frequency and use cases of Intravenous forms (IVF).Material and methods. REGION-IM is a multicenter prospective Russian registry of acute myocardial infarction (AMI). The database records demographic, anamnestic, clinical characteristics of patients, results of laboratory and instrumental examinations. The patient’s recruitment was carried out from 01.11.2020 to 30.06.2023. Overall, 10,884 patients with AMI were included in the MI REGION, of which 3252 patients with non-STEMI and 7631 — with acute myocardial infarction with ST segment elevation (STEMI), information on the appointment or refusal of IV therapy on the first day of hospitalization is present for 7597 patients with STEMI.Results. On the first day after hospitalization, 1.2% (n=91) of patients with STEMI received IVF therapy. In all cases, metoprolol was used at an average daily dose of 4.43 mg. The majority of patients (61.5%, n=56) were transferred to oral administration of BB on the first day, another 33% of patients (n=30) — the next day, 4.4% (n=4) received only intravenous BB, one (1.1%) information is missing due to the transfer to another hospital. The most common relative and absolute contraindications to the appointment of BB — acute heart failure (AHF), including Killip II, and systolic blood pressure less than 120 mmHg. They were observed in less than 20% of all patients with STEMI and in 13% and 12% of patients who received IVF. 74% of patients received oral medications on the first day. Oral forms of BB were used to initiate therapy 61 times more often than IVF of BAB (p&lt;0.0001). Hospital mortality among all patients with STEMI was 4.3% (n=328). Of these, 3.3% (n=249) — cardiac death, 0.7% (n=58) — non-cardiac cause of death, 0.3% (n=21) — the cause of death is not specified. In the group of patients who received IVF, 2.2% died (n=2, of which 1 was a cardiac cause, 1 was not indicated), 4.3% did not receive it (n=326, 76% was a cardiac cause). There was no statistically significant difference in hospital mortality in patients treated with IVF and those who did not receive IVF.Conclusion. The results of the REGION-IM registry demonstrate an unreasonably rare frequency of IVF use in the early stages of the disease in patients with STEMI. Intravenous administration of metoprolol at an average total dose of about 4-5 mg on the first day of hospitalization with further transition to oral administration of BAB was safe. There was no significant difference in the frequency of deaths in the hospital, cases of AHF, cardiogenic shock, severe conduction disorders in the form of grade II-III AV block between the groups of patients who received and did not receive IVF.

Application of norepinephrine in the treatment of septic shock: a meta-analysis.

To systematically evaluate the efficacy and safety of norepinephrine in the treatment of septic shock. Literature retrieval of eligible randomized controlled trials (RCTs) on norepinephrine in the treatment of septic shock was performed in three English databases including PubMed, Web of Science, and Medline from database establishment to October 1, 2023. The Cochrane risk bias tool was used to evaluate the quality of the included literature. RevMan 5.3 software was used for meta-analysis. A total of 14 RCTs were included in this study, and the risk of bias was low. Our meta-analysis showed that the norepinephrine group had significantly better outcomes in reducing the 28-day mortality rate (RR = 0.92; 95% CI, 0.86 ~ 0.99; P = 0.03), the incidence of arrhythmia (RR = 0.54; 95% CI, 0.45 ~ 0.64; P < 0.0001), and the length of stay in intensive care unit (ICU) (MD = - 1.03; 95% CI, - 1.85 to approximately - 0.21; P = 0.01) than those of the control group. However, there were no statistically significant differences in in-hospital mortality rate (RR = 0.97; 95% CI, 0.90 ~ 1.04; P = 0.4), the 90-day mortality rate (RR = 1.07; 95% CI, 0.97 ~ 1.18; P = 0.15), length of hospital stay (MD = 0.03; 95% CI, - 1.13 ~ 1.18; P = 0.96), and the rate of achieving target MAP (RR = 1.27; 95% CI, 0.72 ~ 2.26; P = 0.41) between the norepinephrine group and the control group. Norepinephrine has the advantages of improving 28-day mortality, shortening ICU hospitalization time, and reducing the incidence of arrhythmia. It is a more effective choice for the treatment of septic shock than other vasopressors, and the incidence of arrhythmia is low.

The impact of admitting ward on resource utilization and outcomes among hospitalized cancer survivors.

36 Background: With improvements in both early detection and cancer treatment, there is a growing population of cancer survivors; with a corresponding increase in acute care use. However, models of inpatient care delivery for cancer survivors differ between hospitals and regions, which may impact resource use and outcomes. Understanding how different models influence outcomes may help define optimal models for cancer inpatient care delivery. Methods: We created a multicenter cohort of all cancer patients admitted to medical wards across 26 hospitals in Ontario, Canada from 2015 to 2022, and deterministically linked population level administrative data including ambulatory oncology data, with each hospital’s patient-level electronic information (pharmacy, orders, notes, labs/imaging and results). Multivariable regression models compared characteristics and outcomes between patients admitted on oncology wards vs non-oncology wards adjusting for age, sex, income quintile, rurality, immigrant status, receiving IV systemic therapy within 120 days and comorbidity scores. Results: In total, there were 370,118 hospitalizations from 191,990 unique patients. Among these hospitalizations, 38,075 episodes (10%) were on an oncology ward. Median time from cancer diagnosis to hospitalization was 4 years; 10% received IV systemic therapy within 120 days and 16% within 1 year. The most common disease sites were GU (21%), GI (20%), breast (12%) and lung (10%). The most common discharge diagnoses from oncology wards were inpatient chemotherapy (9%), febrile neutropenia (7%), NHL (4%), AML (4%), myeloma (3%); while for non-oncology wards were heart failure (5%), palliative care (4%), UTI (2%), pneumonia (2%), acute renal failure (2%). In general, cancer patients admitted on oncology wards were younger (64 vs 76), had shorter length of stay (LOS; 9.6 vs 10.1 days), less in-hospital mortality (8% vs 11%), greater 30-day re-admission rates (30% vs 15%) and were more likely to undergo CTs (28% vs 21%), MRIs (11% vs 9%) and interventional procedures (8% vs 6%) (p&lt;0.001, all). Subgroup analysis focusing on the top 5 discharge diagnoses from non-oncology wards, showed that despite no difference in in-hospital mortality rates (aOR 0.92 95% CI [0.58-1.46] p=0.73), admission to a non-oncology ward for those diagnoses was associated with shorter LOS (aOR 0.84 [0.78-0.90] p&lt;0.001), reduced 30-day re-admission rates (aOR 0.60 [0.48-0.75] p&lt;0.001), and reduced use of CTs (aOR 0.60 [0.49-0.74] p&lt;0.001), MRIs (aOR 0.36 [0.25-0.52] p&lt;0.001), and interventional procedures (aOR 0.43 [0.29-0.64] p&lt;0.001). Conclusions: There are differences in resource use and outcomes for cancer survivors hospitalized on oncology versus non-oncology wards, including for patients with the same discharge diagnosis. To optimize inpatient cancer care delivery for hospitalized cancer survivors, further exploration of care models is needed.

The Impact of the Pandemic of COVID-19 on the Head Injury Fast-Track System and Surgical Outcome.

Objective This study aims to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the head injury fast-track system and surgical treatment outcomes. Materials and Methods A retrospective review was conducted on patients who underwent emergency neurological procedures according to the head injury fast-track system. Data from April 2018 to April 2020 (pre-COVID) were compared with data from May 2020 to May 2022 (during COVID). Results The analysis comprised 128 patients in the prepandemic group and 119 patients in the pandemic group, with 5 patients diagnosed with COVID infection during the pandemic. Acute subdural hematoma resulting from motorcycle accidents was the most common diagnosis in both groups (56.3 and 47.5%, respectively). The initial Glasgow coma scale (GCS) score was significantly lower during the pandemic compared to the prepandemic period ( p = 0.025). Time metrics in the emergency department, including door to computed tomography (CT), emergency room (ER) exit, and incision times, were significantly longer in the pandemic group ( p < 0.05). However, there were no statistically significant differences in in-hospital mortality rates (25.8 and 17.7%, respectively; p = 0.12) or the percentage of patients with a favorable functional outcome (Glasgow outcome scale ≥4). At 1 month, a favorable functional outcome was observed in 51.6% of prepandemic patients and 57.1% of pandemic patients ( p = 0.69), while at 6 months, the percentages were 56.8 and 64.5%, respectively ( p = 0.23). Conclusions Our study revealed significant delays in hospital processes for head injuries during the COVID-19 pandemic. However, we found no significant impact on mortality rates or functional outcomes of patients.

Stop the Bleed-Wait for the Ambulance or Get in the Car and Drive? A Post Hoc Analysis of an EAST Multicenter Trial.

Background: The Stop the Bleed campaign gives bystanders an active role in prehospital hemorrhage control. Whether extending bystanders' role to private vehicle transport (PVT) for urban penetrating trauma improves survival is unknown, but past research has found benefit to police and PVT. We hypothesized that for penetrating trauma in an urban environment, where prehospital procedures have been proven harmful, PVT improves outcomes compared to any EMS or advanced life support (ALS) transport.Methods: Post-hoc analysis of an EAST multicenter trial was performed on adult patients with penetrating torso/proximal extremity trauma at 25 urban trauma centers from 5/2019-5/2020. Patients were allocated to PVT and any EMS or ALS transport using nearest neighbor propensity score matching. Univariate analyses included Wilcoxon signed rank or McNemar's Test and logistic regression.Results: Of 1999 penetrating trauma patients in urban settings, 397 (19.9%) had PVT, 1433 (71.7%) ALS transport, and 169 (8.5%) basic life support (BLS) transport. Propensity matching yielded 778 patients, distributed equally into balanced groups. PVT patients were primarily male (90.5%), Black (71.2%), and sustained gunshot wounds (68.9%). ALS transport had significantly higher ED mortality (3.9% vs 1.9%, P = 0.03). There was no difference in in-hospital mortality rate, hospital LOS, or complications for all EMS or ALS only transport patients.Conclusion: Compared to PVT, ALS, which provides more prehospital procedures than BLS, provided no survival benefit for penetrating trauma patients in urban settings. Bystander education incorporating PVT for early arrival of penetrating trauma patients in urban settings to definitive care merits further investigation.

Evaluation of end-organ protection in newborns and infants after surgery of aortic arch hypoplasia: A prospective randomized study.

Surgical repair of aortic arch hypoplasia in children requires a "dry" surgical field with reliable end-organ protection. Perfusion strategies commonly involve deep hypothermic circulatory arrest (DHCA) and variations of the continuous perfusion techniques, such as selective antegrade cerebral perfusion (SACP) and full-flow perfusion with double aortic cannulation (DAC). We aimed to evaluate the end-organ protection in the surgery of aortic arch hypoplasia in newborns and infants using DHCA and DAC. 66 newborns and infants with aortic arch hypoplasia and biventricular anatomy were enrolled in this prospective study. Patients were randomly assigned into two groups according to the perfusion strategy - DHCA (n = 33); and DAC (n = 33). Primary endpoint: acute kidney injury (AKI), graded according to the KDIGO score. Secondary endpoints: neurological sequelae (pre- and postoperative MRI), in-hospital mortality. The lowest temperature was 32 (28; 34)°С in the DAC group and 23 (20; 25)°С in the DHCA group. The patients with DAC had lower incidence of AKI (6 patients (18.2%) versus 19 patients (57.6%); p = .017). In the multivariate analysis, the inotropic index at 48h was identified as a risk factor, increasing the risk of AKI by 4%. The DHCA group was associated with a 3.8-fold increase in the risk of AKI. There was no difference in hospital mortality between the DAC and DHCA groups (1 patient (3%) versus 3 patients (9.1%); p = .61). Neurological sequelae by MRI scan were observed in 18 patients (54.5%) in the DHCA group compared to 5 patients (15.15%) in the DAC group (p = .026). The only risk factor identified in the multivariate analysis for neurological lesions on MRI scan was the DHCA group, which increased the risk by 8.8 times. Surgical reconstruction of the aortic arch hypoplasia using the method of full-body perfusion reduces the incidence of neurological lesions and renal complications requiring renal replacement therapy compared with the deep hypothermic circulatory arrest in neonates and infants.

Extended ischemic times during exvivo lung perfusion is not associated with increased mortality.

The purpose of this study was to identify the association of increasing ischemic times in recipients who receive lungs evaluated by exvivo lung perfusion (EVLP) and their association with outcomes following lung transplantation. Lung transplant recipients who received an allograft evaluated by EVLP were identified from the United Network for Organ Sharing (UNOS) Database from 2016-2023. Recipients were stratified into three groups based on total ischemic time (TOT): short TOT (STOT, 0 to <7 h), medium TOT (MTOT, 7> to <14 h), and long TOT (LTOT, +14 h). The groups were assessed with comparative statistics and Kaplan-Meier methods. A Cox regression was created to determine the association of ischemic time in EVLP donors and long-term mortality. Recipients in the LTOT group had significantly longer length of stay and post-operative extracorporeal membrane use at 72 h (p < 0.05 for both). Additionally, they had nonsignificant increases in rate of stroke (4.7%, p = 0.05) and primary graft dysfunction grade 3 (PGD3, 27.5%, p = 0.082). However, there was no significant difference in hospital mortality or mid-term survival (p > 0.05 for both). On multivariable analysis, ischemic time was not associated with increased mortality whereas increasing recipient age, preoperative ECMO use and donation after circulatory death donors were (p < 0.05 for all). If EVLP technology is available, under certain circumstances, surgeons should not be dissuaded from using an allograft with extended ischemic time.

CLINICAL APPLICATION OF EARLY POSTOPERATIVE NUTRITIONAL SUPPORT IN PATIENTS WITH HIGH-RISK VALVULAR HEART DISEASE.

Background : The treatment strategy of early nutritional support after cardiac surgery has gradually been adopted. However, there are no scientific guidelines for the timing and specific programs of early nutritional support. Methods: A retrospective, single-center analysis (2021-2023) was carried out including elderly patients who were admitted for valvular heart disease and received open-heart valve replacement surgery. We designated patients who started the optimized nutritional support after surgery as the optimized enteral nutritional support strategy TN (EN) group and those who received traditional nutritional support as the traditional nutritional support strategy (TN) group. The nutritional and immune indexes, postoperative complications, length of hospital stay, and hospitalization cost of the two groups were compared and analyzed. Results: We identified 378 eligible patients, comprising 193 (51%) patients in the EN group and 185 (49%) patients in the TN group. There was no significant difference in hospital mortality between the two groups, but the proportion of nosocomial pneumonia was significantly lower in the EN group than in the TN group ( P < 0.001). In the Poisson regression analysis, EN was not associated with an increase in gastrointestinal complications ( P = 0.549). The EN group also seemed to have shorter hospital stays and lower hospitalization expenses ( P < 0.001). In the comparison of postoperative gastrointestinal complications, fewer patients experienced diarrhea ( P = 0.021) and abdominal distension ( P = 0.033) in the EN group compared with the TN group. Conclusion: The optimal nutritional support strategy could effectively improve the clinical outcome of high-risk patients with valvular heart disease.

Trends and outcomes of inpatient cardiac implantable electronic device transvenous lead extractions: a nationwide analysis.

Higher rates of CIED implantations have been associated with an increased rate of lead failures and complications resulting in higher rates of transvenous lead extractions (TLE). To assess the trends TLE admissions and evaluate the patient related predictors of safety outcomes. National Readmission Database was queried to identify patients who underwent TLE from January 2016 to December 2019. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality in patients undergoing TLE. Additionally, we compared trends and outcomes of TLE among patients with prior sternotomy versus those without prior sternotomy and analyzed sex-based differences among patients undergoing TLE. We identified 30,128 hospitalizations for TLE. The index admission in-hospital mortality rate was 3.21% with cardiac tamponade happening in 1.46% of the admissions. Age, infective endocarditis, CKD, congestive heart failure and anemia were associated with higher in-hospital mortality rates. There was a lower rate of in-hospital mortality in patients with history of prior sternotomy versus patients without (OR 0.72, CI: 0.59-0.87, p-value < 0.001). There was no difference in in-hospital mortality rate between males and females. Females had a shorter length and a higher cost of stay when compared to male gender. TLE admissions continue to increase. Overall rates of mortality and complications are relatively low. Patients with prior sternotomy had better outcomes and less complications when compared to those without prior sternotomy. Female gender is associated with higher rates of cardiac tamponade, yet shorter length of stay with lower cost.

Outcomes after hip fracture surgery in patients receiving non-steroidal anti-inflammatory drugs alone, acetaminophen alone, or both.

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone. This nationwide retrospective cohort study used data from the Diagnosis Procedure Combination database. We included patients aged ≥ 18 years who underwent surgery for hip fractures and received acetaminophen combined with NSAIDs (combination group), NSAIDs alone (NSAIDs group), or acetaminophen alone (acetaminophen group) preoperatively, between April 2010 and March 2022. Primary outcomes were in-hospital mortality and complications. Secondary outcomes were opioid use postoperatively; readmission within 90 days, one year, and two years; and total hospitalization costs. We used propensity score overlap weighting models, with the acetaminophen group as the reference group. We identified 93,018 eligible patients, including 13,068 in the combination group, 29,203 in the NSAIDs group, and 50,474 in the acetaminophen group. Propensity score overlap weighting successfully balanced patient characteristics among the three groups, with no significant difference in in-hospital mortality rates observed among the groups (combination group risk difference 0.0% (95% CI -0.5 to 0.4%); NSAIDs group risk difference -0.2% (95% CI -0.5 to 0.2%)). However, the combination group exhibited a significantly lower risk of in-hospital complications than the acetaminophen group (risk difference -1.9% (95% CI -3.2 to -0.6%)) as well as a significantly lower risk of deep vein thrombosis (risk difference -1.4% (95% CI -2.2 to -0.7%)). Furthermore, total hospitalization costs were higher in the NSAIDs group than in the acetaminophen group (difference USD $438 (95% CI 249 to 630); p < 0.001). No significant differences in other secondary outcomes were observed among the three groups. The combination of acetaminophen with NSAIDs appears to be safe and advantageous in terms of reducing in-hospital complications.

Risk factor profile and outcomes in young patients presenting with acute ST-segment elevation myocardial Infarction

Abstract Introduction ST-elevation myocardial infarction (STEMI) is more prevalent in the elderly population1, but is now becoming more common in the younger population. It has been of particular concern due to its potential for premature death and long-term morbidity. Early identification and timely modification of risk factors in this population is critical2,3. Secondary prevention issues in populations are well studied, and such data for young adults are lacking in the literature. Purpose The purpose of this study was to compare pattern of traditional CVD risk factors, hospital mortality and major adverse cardiac events at discharge in young versus old patients (≤45years and above 45 years age respectively) admitted with STEMI and undergoing primary PCI. Methods This retrospective cohort study was conducted on consecutive patients presenting with STEMI between June 2013 and June 2018 in a single centre cardiac only tertiary care setup. Institute’s registry is fashioned along and is affiliated with US NCDR. Patients with cardiac arrest or cardiogenic shock at arrival were excluded. MACE was defined as post PCI cardiac arrest or cardiogenic shock, heart failure, major bleed or hospital death. Results Total of 5343 patients were admitted with STEMI during study period, after exclusion data of 1642 patients were analyzed. Table 1 demonstrates demographic and historical characteristics of the study population. Among young patients, the frequency of the male gender,any tobacco use and family history of premature coronary artery disease were significantly higher (all p values &amp;lt; 0.001). While in older STEMI patients frequency of heart failure, hypertension, prior myocardial infarction, diabetes mellitus ,abnormal creatinine clearance (&amp;lt;90 mL/min/1.73 m²) , multi-vessel coronary disease, advanced Killip class and higher body mass index was more prevalent (all P&amp;lt;0.001). Table 2 demonstrates predictors of in hospital death and MACE. Among young patients advanced Killip class and femoral access site(all P values &amp;lt;0.001), diabetes mellitus (p=0.03), abnormal creatinine clearance(p=0.04),and left ventricular ejection fraction less than 40%(p=0.01), were more significant in-hospital mortality predictor where as advanced Killip class,Left ventricular ejection fraction less than 40% male gender(p=0.04), diabetes mellitus(p=0.001),femoral access site(p=0.001), and Left ventricular ejection fraction less than 40% were more significant MACE predictors (all P&amp;lt;0.001). Conclusion There were no significant difference in hospital mortality and MACE among young versus old STEMI patients when adjusted for diabetes mellitus, abnormal creatinine clearance (&amp;lt;90 mL/min/1.73 m²), multi-vessel coronary disease, advanced Killip class. Tobacco use is the main modifiable risk factors for young patients with STEMI. Surprisingly, being a woman and having a positive family history with premature coronary artery disease were protective.

Comparison of Levosimendan Versus Milrinone After the Arterial Switch Operation for Infants ≤3 kg.

Background: Various inotropes and inodilators have been utilized to treat low cardiac output syndrome after the arterial switch operation. The use of levosimendan, a calcium sensitizer has been limited in this setting. This study compares the effects of levosimendan with milrinone in managing low cardiac output after the arterial switch operation. Methods: A retrospective, comparative study was conducted in a tertiary care hospital on patients weighing up to 3 kg undergoing the arterial switch operation between January 2017 and January 2022. Patients received a loading dose followed by continuous infusion of either levosimendan or milrinone. Echocardiographic, hemodynamic and biochemical parameters were compared. Results: Forty-three patients received levosimendan and 42 patients received milrinone as the primary test drug. Cardiac index of less than 2.2 L/min/m2 on postoperative day 1 and 2 was found in 9.3% and 2.3% of patients receiving levosimendan versus 26.2% and 11.9% in those receiving milrinone, respectively (P = .04 and .08, respectively). Early lactate-clearance and better central venous oxygen saturations were noted in the levosimendan group. Prevalence of acute kidney injury was higher in the milrinone group (50% vs 28%; P = .03). Use of peritoneal dialysis in the milrinone group versus levosimendan was 31% and 16.3%, respectively (P = .11). There was no difference in hospital mortality between the groups (milrinone, 3; levosimendan, 2, P = .62). Conclusions: Levosimendan is safe and as effective as milrinone to treat low cardiac output syndrome occurring in neonates after the arterial switch operation. In addition we found that levosimendan was renal protective when compared with milrinone.

Intubation and In-Hospital Mortality After Trauma With Glasgow Coma Scale Score Eight or Less–A Cohort Study

IntroductionMost trauma societies recommend intubating trauma patients with Glasgow Coma Scale (GCS) scores ≤8 without robust supporting evidence. We examined the association between intubation and 30-d in-hospital mortality in trauma patients arriving with a GCS score ≤8 in an Indian trauma registry. MethodsOutcomes of patients with a GCS score ≤8 who were intubated within 1 h of arrival (intubation group) were compared with those who were intubated later or not at all (nonintubation group) using various analytical approaches. The association was assessed in various subgroup and sensitivity analyses to identify any variability of the effect. ResultsOf 3476 patients who arrived with a GCS score ≤8, 1671 (48.1%) were intubated within 1 h. Overall, 1957 (56.3%) patients died, 947 (56.7%) in the intubation group and 1010 (56.0%) in the nonintubation group, with no significant difference in mortality (odds ratio = 1.2 [confidence interval, 0.8-1.8], P value = 0.467) in multivariable regression and propensity score-matched analysis. This result persisted across subgroup and sensitivity analyses. Patients intubated within an hour of arrival had longer durations of ventilation, intensive care unit stay, and hospital stay (P < 0.001). ConclusionsIntubation within an hour of arrival with a GCS score ≤8 after major trauma was not associated with differences in-hospital mortality. The indications and benefits of early intubation in these severely injured patients should be revisited to promote optimal resource utilization in LMICs.

Thick Liquids and Clinical Outcomes in Hospitalized Patients With Alzheimer Disease and Related Dementias and Dysphagia

Oropharyngeal dysphagia is common in hospitalized patients with Alzheimer disease and related dementias (ADRD). Although the use of thick liquids in patients with dysphagia has been shown to reduce aspiration on direct visualization, there is no clear evidence that this practice translates into improved clinical outcomes. To determine whether a diet of thick liquids compared with thin liquids is associated with improved outcomes in hospitalized patients with ADRD and dysphagia. This cohort study included adults aged 65 years and older with ADRD who were admitted to the medicine service across 11 diverse hospitals in New York between January 1, 2017, and September 20, 2022, with clinical suspicion of dysphagia during hospitalization and survival for at least 24 hours after hospital arrival. Patients were grouped according to whether at least 75% of their hospital diet consisted of a thick liquid diet or a thin liquid diet. Propensity score matching was used to balance covariates across the 2 groups for the following covariates: demographics (eg, age, sex), baseline clinical characteristics (eg, Charlson Comorbidity Index), and acute presentation (eg, respiratory diagnosis, illness severity, delirium). Hospital outcomes included mortality (primary outcome), respiratory complications (eg, pneumonia), intubation, and hospital length of stay (LOS). Of 8916 patients with ADRD and dysphagia included in the propensity score matched analysis, the mean (SD) age was 85.7 (8.0) years and 4829 were female (54.2%). A total of 4458 patients receiving a thick liquid diet were matched with 4458 patients receiving a thin liquid diet. There was no significant difference in hospital mortality between the thick liquids and thin liquids groups (hazard ratio, 0.92; 95% CI, 0.75-1.14]; P = .46). Compared with patients receiving thin liquids, patients receiving thick liquids were less likely to be intubated (odds ratio [OR], 0.66; 95% CI, 0.54-0.80), but they were more likely to have respiratory complications (OR, 1.73; 95% CI, 1.56-1.91). This cohort study emphasizes the need for prospective studies that evaluate whether thick liquids are associated with improved clinical outcomes in hospitalized patients with ADRD and dysphagia.

Effects of high-flow nasal cannula oxygen therapy in bronchiectasis and hypercapnia: a retrospective observational study

BackgroundThe effectiveness of high-flow nasal cannula (HFNC) therapy in patients with bronchiectasis experiencing hypercapnia remains unclear. Our aim was to retrospectively analyze the short-term outcomes of HFNC therapy in such patients, and to further explore the predictors of HFNC treatment failure in this particular patient population.MethodsA retrospective review was conducted on patients with bronchiectasis who received HFNC (n = 70) for hypercapnia (arterial partial pressure of carbon dioxide, PaCO2 ≥ 45 mmHg) between September 2019 and September 2023.ResultsIn the study population, 30% of patients presented with acidemia (arterial pH < 7.35) at baseline. Within 24 h of HFNC treatment, there was a significant reduction in PaCO2 levels by a mean of 4.0 ± 12.7 mmHg (95% CI -7.0 to -1.0 mmHg). Concurrently, arterial pH showed a statistically significant increase with a mean change of 0.03 ± 0.06 (95% CI 0.01 to 0.04). The overall hospital mortality rate in our study was 17.5%. The median length of hospital stay was 11.0 days (interquartile range [IQR] 8.0 to 16.0 days). Sub-analysis revealed no statistically significant differences in hospital mortality (19.0% vs. 20.4%, p = 0.896), length of hospital stay (median 14.0 days [IQR 9.0 to 18.0 days] vs. 10.0 days [IQR 7.0 to 16.0 days], p = 0.117) and duration of HFNC application (median 5.0 days [IQR 2.0 to 8.5 days] vs. 6.0 days [IQR 4.9 to 9.5 days], p = 0.076) between the acidemia group and the non-acidemia group (arterial pH ≥ 7.35). However, more patients in the non-acidemia group had do-not-intubate orders. The overall treatment failure rate for HFNC was 28.6%. Logistic regression analysis identified the APACHE II score (OR 1.24 per point) as the independent predictor of HFNC failure.ConclusionsIn patients with bronchiectasis and hypercapnia, HFNC as an initial respiratory support can effectively reduce PaCO2 level within 24 h of treatment. A high APACHE II score has emerged as a prognostic indicator for HFNC treatment failure. These observations highlight randomized controlled trials to meticulously evaluate the efficacy of HFNC in this specific population.

Outcomes of percutaneous versus surgical tracheostomy in an Australian Quaternary Intensive Care Unit: An entropy-balanced retrospective study.

Studies comparing percutaneous tracheostomy (PT) and surgical tracheostomy (ST) complications in the critically ill patient population with high acuity, complexity, and severity of illness are sparse. This study evaluated the outcomes of elective PT versus ST in such patients managed at a quaternary referral center. The primary aim was to detect a difference in hospital mortality between the two techniques. The secondary aims were to compare Intensive Care Unit (ICU) mortality, complications (including stoma site, tracheostomy-related, and decannulation complications), ICU and hospital length of stay, and time to decannulation. This was a single-center retrospective observational study of ICU admission from August 2018 to August 2021. Patients were included if an elective tracheostomy was performed during their ICU admission. Patients with a pre-existing tracheostomy and those who underwent an obligatory tracheostomy requirement (e.g. total laryngectomy) were excluded. Cohorts were matched using Hainmueller's entropy balancing. Binary data were evaluated using logistic regression and continuous data with ordinary least squares regression. 349 patients with a tracheostomy were managed in the ICU during the observation period. They were predominantly males (75% in PT; 67% in ST), with a mean age in the PT and ST group of (47; SD = 18) and (55; SD = 16), respectively. After exclusion, 135 patients remained, with 63 in the PT group and 72 in the ST group. Patients receiving ST were significantly older with a higher Body Mass Index (BMI) than the PT group. There were no significant differences in gender, Acute Physiological And Chronic Health Evaluation (APACHE) III, and the Australian and New Zealand Risk Of Death (ANZROD) between the two groups. There was no difference in hospital mortality between groups (OR 0.91, CI 0.26-3.18, p = 0.88). There were also no differences in ICU mortality, ICU and hospital length of stay, and time to decannulation. PT was associated with a greater likelihood of complications (OR 4.19; 95% CI 1.73-10.13; p < 0.01). PT was associated with a greater risk of complications in those who had this performed early (<10 days of intubation) as well as late (>10 days of intubation). Percutaneous tracheostomy was associated with higher complications compared to surgical tracheostomy. They were related to tracheostomy cuff deflation, stomal site bleeding and infection, sputum plugging, and accidental and failed decannulation. These findings have identified opportunities to improve patient outcomes.

Comparison of disease and economic burden between MRSA infection and MRSA colonization in a university hospital: a retrospective data integration study

BackgroundAlthough there is a growing concern and policy regarding infections or colonization caused by resistant bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), the prognosis of MRSA infections compared to that of methicillin-susceptible Staphylococcus aureus (MSSA) infections remains controversial. Moreover, there have not been any studies comparing both the burden of disease and its impact on the healthcare economy between MRSA infection and colonization while adjusting for confounding factors. These comparisons are crucial for developing effective infection control measures and healthcare policies. We aimed to compare the disease and economic burden between MRSA and MSSA infections and between MRSA infection and colonization.MethodsWe retrospectively investigated data of 496 in-patients with MRSA or MSSA infections and of 1178 in-patients with MRSA infections or MRSA colonization from a university hospital in Japan from 2016 to 2021. We compared in-hospital mortality, length of stay, and hospital charges between in-patients with MRSA and MSSA infections and those with MRSA infections and MRSA colonization using multiple regressions. We combined surveillance data, including all microbiological test results, data on patients with infections, treatment histories, and clinical outcomes, to create the datasets.ResultsThere was no statistically significant difference in in-hospital mortality rates between matched MRSA vs. MSSA infections and MRSA infection vs. colonization. On the contrary, the adjusted effects of the MRSA infection compared to those of MSSA infection on length of stay and hospital charges were 1.21-fold (95% confidence interval [CI] 1.03–1.42, P = 0.019) and 1.70-fold (95% CI 1.39–2.07, P < 0.00001), respectively. The adjusted effects of the MRSA infection compared to those of MRSA colonization on length of stay and hospital charges were 1.41-fold (95% CI 1.25–1.58, P < 0.00001) and 1.53-fold (95% CI 1.33–1.75, P < 0.00001), respectively. Regarding confounding factors, hemodialysis or hemofiltration was consistently identified and adjusted for in the multiple regression analyses comparing MRSA and MSSA infections, as well as MRSA infection and MRSA colonization.ConclusionsMRSA infection was associated with longer length of stay and higher hospital charges than both MSSA infection and MRSA colonization. Furthermore, hemodialysis or hemofiltration was identified as a common underlying factor contributing to increased length of stay and hospital charges.

Risk of Bleeding in Elderly Patients Undergoing Transcatheter Aortic Valve Implantation or Surgical Aortic Valve Replacement

Background: Bleeding complications are strong predictors of mortality and major morbidity in elderly patients undergoing surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI). Despite the high prevalence of frailty in this population, little is known about its effects on bleeding risk. Methods: We conducted a retrospective observational study of 502 patients undergoing isolated SAVR or TAVI between January 2015 and February 2022. The occurrence of blood products transfusions and MACEs were the primary endpoints. In-hospital mortality was the secondary endpoint. Results: The Elderly group (age &lt; 80 years old) included 475 subjects, whereas the Very Elderly group (age ≥ 80 years old) included 127 patients. The need for blood product transfusion was similar among the two groups, regardless of the type of procedure. MACEs occurred similarly between groups [SAVR: Elderly group: 7.9% vs. Very Elderly group: 8.6%, p = 0.864; TAVI: Elderly group: 5.5% vs. Very Elderly group: 8.7%, p = 0.378]. The was no difference in in-hospital mortality rate in patients submitted to TAVI, whereas very elderly patients had higher mortality rate compared to the elderly patients submitted to SAVR [SAVR: Elderly group: 0% vs. Very Elderly group: 2.8%, p = 0.024; TAVI: Elderly group: 4,8% vs. Very Elderly group: 8%, p = 0.389]. Conclusions: Age alone should not be considered as a predictive factor for post-operative adverse events or in-hospital mortality in elderly patients with severe symptomatic AS.

Study of the course of recurrent myocardial infarction in the acute stage within the framework the hospital register

Aim. To study the features of the course of primary and recurrent myocardial infarction and compare their prognosis in the acute stage of the disease within the framework of the hospital register of the vascular center.Material and methods. The data from the acute coronary syndrome register of N. V. Sklifosovsky Research Institute for Emergency Medicine were used. The inclusion criteria were: transmural acute myocardial infarction (AMI) with ST-segment elevation (codes I21.0-I21.3 according to the International Classification of Diseases); permanent residence in Moscow and the Moscow region. The described part of the study included all patients with transmural myocardial infarction (codes I21.0-I.21.3) admitted from January 1, 2017 to December 31, 2017. Of the AMI patients admitted during this period (n=329), 214 met the inclusion criteria, with primary AMI in 153 and recurrent AMI in 61.Results. Patients with recurrent AMI were significantly older, more often had a disability group. Smoking and arterial hypertension were more frequent risk factors among patients with recurrent AMI than in primary AMI. All indices reflecting the severity of coronary artery disease and its complications were also significantly more common in the group with recurrent AMI. Diabetes mellitus was more common in these patients. Taking medications before hospitalization, as well as the regularity of this intake, were significantly more common in patients who had repeated AMI. The mortality rate of patients with recurrent AMI was 4.6 times higher than that of patients with primary AMI. Such complications as atrial fibrillation and flutter, intracardiac conduction disturbance requiring temporary endocardial stimulator placement, acute heart failure requiring intra-aortic balloon counterpulsation, respiratory failure requiring artificial ventilation, cardiogenic shock were significantly more common in patients with recurrent AMI. Kaplan-Meyer curves clearly demonstrate the differences in hospital mortality among the two groups of patients. These curves also clearly show that patients with primary AMI died mostly in the first days of the disease, but patients with recurrent AMI could die at a much later date, up to 12 days after admission. Analysis of factors determining the mortality risk during hospitalization showed that recurrent AMI is an independent predictor of death.Conclusion. The results of our work indicate the need for prompt identification of patients who had previously undergone AMI upon their admission to the vascular center, as well as the development of more active prevention tactics for such patients.
