Prognostic factors in mobility disability among elderly patients in the emergency department: A single-center retrospective study.

Aim: We aimed to evaluate the clinical characteristics and outcomes of elderly critically ill patients and identify prognostic factors for mobility disability at discharge. Methods: This single-center, retrospective cohort study investigated the period from April 2020 to January 2021. Patients ≥75 years old transferred to our emergency department and admitted to the intensive care unit (ICU) or intermediate unit in our hospital were eligible. Demographics, clinical characteristics, nutritional indicators, and nutritional screening scores were collected from chart reviews and analyzed. The primary outcome was the prevalence of mobility disability, compared to that of no mobility disability. Results: A total of 124 patients were included in this present study. Median age was 83.0 years (interquartile range [IQR], 79.8-87.0 years) and 48 patients (38.7%) were female. Fifty-two patients (41.9%) could not walk independently at discharge (mobility disability group). The remaining 72 patients were in the no mobility disability group. Multiple logistic regression analyses revealed clinical frailty scale (CFS) score ≥5 (odds ratio [OR] = 6.63, 95% confidence interval [CI] = 2.51-17.52, p < 0.001), SOFA score ≥6 (OR = 6.11, 95% CI = 1.57-23.77, p = 0.009), and neurological disorder as the main cause on admission (OR = 4.48, 95% CI = 1.52-13.20, p = 0.006) were independent and significant prognostic factors for mobility disability at discharge. Conclusion: Among elderly patients admitted to the emergency department, CFS ≥5, SOFA ≥6, and neurological disorders were associated with mobility disability at hospital discharge.

Functional Recovery and Nutrition Management among Severe COVID-19 Cases during Post-extubation Hospitalization: A Case Series.

Background: Many patients with coronavirus disease 2019 (COVID-19) develop malnutrition after a prolonged stay in the intensive care unit (ICU) with mechanical ventilation. Early enteral nutrition is recommended, but optimal nutrition management during post-extubation recovery remains challenging. Cases: The subjects were 12 acute respiratory distress syndrome patients with COVID-19 (9 men, 3 women; median age, 55.6 years). We reviewed patient characteristics, physical function, and nutrient intake during hospitalization from just after extubation to discharge. During this period, the median Functional Oral Intake Scale score improved from 4.5 (interquartile range [IQR] 3.3-5.3) to 7.0 (IQR 5.8-7.0), the median Medical Research Council (MRC) scale score improved from 45.0 (IQR 39.3-48.5) to 53.5 (IQR 47.5-59.3), and the median Barthel index improved from 7.5 (IQR 0-16.3) to 72.5 (IQR 42.5-95.0). In 3 patients, the MRC scale score remained below 48 before discharge, indicating that ICU-acquired weakness had been prolonged. The median daily caloric intake during this phase increased from 6.9 kcal/kg per day (3.5-10.2 kcal/kg per day) to 24.8 kcal/kg per day (21.0-27.9 kcal/kg per day). About half of these patients showed caloric intake below 25 kcal/kg per day before discharge. Based on the Global Leadership Initiative on Malnutrition (GLIM) diagnostic scheme, 10 patients were diagnosed with malnutrition during hospitalization. Discussion: Physical function improved in more than half of the patients, but nutritional status was not recovered. More studies for nutritional management are required to prevent malnutrition and to enhance functional recovery during the post-extubation rehabilitation phase.

Eleven-year retrospective study characterizing patients with severe brain damage and poor neurological prognosis -role of physicians' attitude toward life-sustaining treatment.

BACKGROUND: Severe brain hemorrhage/infarction and cardiac arrest constitute the most critical situations leading to poor neurological prognosis. Characterization of these patients is required to offer successful end-of-life care, but actual practice is affected by multiple confounding factors, including ethicolegal issues, particular in Japan and Asia. The aim of this study is to evaluate the clinical courses of patients with severe brain damage and to assess the preference of end-of-life care for these patients in Japanese hospitals. METHODS: A retrospective observational study was conducted between 2008 and 2018. All intracranial hemorrhage/infarction and cardiac arrest out-patients (n = 510) who were admitted to our two affiliated hospitals and survived but with poor neurologic outcomes were included. Demographic characteristics as well as prognosis and treatment policies were also assessed. RESULTS: Patients were divided into two categories; cases with absent brainstem reflex (BSR) (BSR[-]) and those with preserved BSR (BSR[ +]). The survival rate was higher and the length of hospitalization was longer in patients with BSR[ +] than in those with BSR[-]. Among three life-sustaining policies (i.e., aggressive treatment, withdrawal of treatment, and withholding of treatment), withholding of treatment was adopted to most patients. In BSR[-], the proportion of three treatment policies performed at the final decision did not differ from that at the initial diagnosis on neurological status (p = 0.432). In contrast, this proportion tended to be altered in BSR[ +] (p = 0.072), with a decreasing tendency of aggressive treatment and a modest increasing tendency of withdrawal of treatment. Furthermore, the requests from patients' families to withdraw life-sustaining treatment, including discontinuation of mechanical ventilation, increased, but actual implementation of withdrawal by physicians was less than half of the requests. CONCLUSIONS: BSR constitutes a crucial determinant of mortality and length of hospitalization in comatose patients with severe brain damage. Although the number of withdrawal of life-sustaining treatment tends to increase over time in BSR[ +] patients, there are many more requests from patients' families for withdrawal. Since physicians has a tendency to desist from withdrawing life-sustaining treatment, more in-depth communication between medical staff and patients' families will facilitate mutual understanding over ethicolegal and religious issues and may thus improve end-of-life care.

Effects on physical performance of high protein intake for critically ill adult patients admitted to the intensive care unit: A retrospective propensity-matched analysis.

OBJECTIVES: This study aimed to examine the effects of protein intake on physical performance in critically ill adult patients admitted to the intensive care unit (ICU). METHODS: This was a retrospective cohort study of adult patients mechanically ventilated over 48 h in the ICU who were classified into two groups based on the amount of protein intake: >1.0 g/kg/d (high-protein group) or <1.0 g/kg/d (low-protein group). After adjustment for possible confounding factors with propensity score matching, we compared muscle strength at the time of ICU discharge and the rate of recovery to independent walking between the two groups. RESULTS: One-to-one propensity score matching created 20 pairs. The high-protein group had significantly higher muscle strength than the low-protein group at the time of discharge from the ICU. In addition, the rate of recovery to independent walking before hospital discharge was higher in the high-protein group than the low-protein group (16 of 20 patients [80%] vs. 8 of 20 patients [40%]; P = 0.032). CONCLUSIONS: Our findings indicate that a sufficient amount of protein intake may lead to a higher rate of recovery to independent walking before discharge from the hospital in critically ill patients admitted to the ICU. This finding is likely related to preserved muscle strength at the time of ICU discharge.

Mortality associated with new risk classification of developing refeeding syndrome in critically ill patients: A cohort study.

BACKGROUND & AIMS: Although refeeding syndrome (RFS) has been recognized as a potentially fatal metabolic complication, the definition of RFS has remained unclear. Recently, European researchers suggested an evidence-based and consensus-supported algorithm that consisted of a new RFS risk classification and treatment strategies for medical inpatients. The classification was based on the National Institute for Health and Clinical Excellence (NICE) criteria for patients at risk of developing RFS. In this study, we aimed to investigate the frequency of each applied new risk group and the association between the new classification and mortality in critically ill patients. METHODS: This cohort study was conducted at a Japanese metropolitan tertiary-care university hospital from December 2016 to December 2018. We included critically ill adult patients who were admitted to the intensive care unit (ICU) via the emergency department and who stayed in the ICU for 24 h or longer. We applied the new risk classification based on the NICE RFS risk factors on ICU admission. The main exposure was risk classification of RFS: no risk, low risk, high risk, or very high risk. The primary outcome was in-hospital mortality censored at day 30 after ICU admission. We performed a multivariable analysis using Cox proportional hazard regression. RESULTS: We analyzed 542 patients who met the eligibility criteria. The prevalence of the four RFS risk classification groups was 25.8% for no risk, 25.7% for low risk, 46.5% for high risk, and 2.0% for very high risk. The 30-day mortality was 5.0%, 7.2%, 16.3%, and 27.3%, respectively (log-rank trend test: p < 0.001). In the multivariable Cox regression, adjusted hazard ratios with no risk group as a reference were 1.28 (95% CI 0.48-3.38) for low risk, 2.81 (95% CI 1.24-6.35) for high risk, and 3.17 (95% CI 0.78-12.91) for very high risk. CONCLUSIONS: Approximately half the critically ill patients were categorized as high or very high risk based on the new risk classification. Furthermore, as the risk categories progressed, the 30-day in-hospital mortality increased. Early recognition of patients at risk of developing RFS may improve patient outcomes through timely and optimal nutritional treatment.

Herpes simplex virus type 2 myelitis mimicking ICU-acquired weakness as a complication of meningococcal meningitis: A case report.

Herpes simplex virus 2 (HSV-2) is a well-known cause of neurological complications. This case study describes the first reported case of reactivated HSV-2 myelitis, which was induced by immunosuppression due to sepsis. During the treatment of meningococcal meningitis, the patient developed quadriparesis and was later diagnosed as HSV-2 myelitis, mimicking ICU-acquired weakness. The case emphasizes the importance of excluding viral myelitis before making the diagnosis of ICU-acquired weakness.

Exploratory Observational Study of Extracorporeal Cardiopulmonary Resuscitation for Nonshockable Out-Of-Hospital Cardiac Arrest Occurring After an Emergency Medical Services Arrival: SOS-KANTO 2012 Study Report.

BACKGROUND: The outcomes of patients with nonshockable out-of-hospital cardiac arrest (OHCA) are poor, but may be improved by extracorporeal cardiopulmonary resuscitation (E-CPR). OBJECTIVE: To examine the effects of veno-arterial extracorporeal membranous oxygenation (ECMO) as E-CPR in patients with nonshockable OHCA after emergency medical services (EMS) arrival for whom satisfactory cardiopulmonary resuscitation (CPR) was immediately performed. METHODS: Among 16,452 patients enrolled in the SOS-KANTO 2012 study, we examined data on 531 patients aged ≥ 18 years who performed activities of daily living (ADL) well or had moderate disability before the onset of cardiac arrest (CA) and those with normal spontaneous respiration or pulse palpation upon EMS arrival. CPR was performed immediately after CA onset, and advanced life support was provided upon hospital arrival for these patients. We divided patients into ECMO and non-ECMO groups. We retrospectively analyzed background factors and clinical outcomes. RESULTS: E-CPR was performed on 38 (7.2%) patients. In the univariate analysis, the mean age of the ECMO group was lower, ADL function before onset was more favorable, mean body weight was higher, and the mean interval from onset until hospital arrival was shorter than those in the non-ECMO group. One-to 3-month survival or favorable cerebral function outcome rates were higher in the ECMO group than in the non-ECMO group. In the multivariate analysis, ECMO use and the interval from onset until hospital arrival were independent prognostic factors for favorable cerebral functional outcomes at 1 and 3 months. CONCLUSION: E-CPR may be associated with favorable outcomes in carefully selected patients with nonshockable OHCA.

Clinical outcomes of urinary tract infection caused by extended spectrum beta-lactamase producing Enterobacteriaceae: a retrospective observational study comparing patients with and without systemic inflammatory response syndrome.

AIM: In severe urinary tract infection (UTI), susceptible antibiotics should be given. With the recent increase of multidrug-resistant bacteria, especially extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E), broad-spectrum antibiotics, such as carbapenems, are used more frequently, which could lead to a further increase of multidrug-resistant bacteria. We aimed to analyze the relationship between initial empirical antibiotic appropriateness and clinical outcomes in UTI, especially in patients with systemic inflammatory response syndrome (SIRS) and ESBL-E. METHODS: A retrospective observational study from 2012 to 2017. RESULTS: Among urine culture-positive cases with ≥105 colony-forming units/mL (n = 1,880), true UTI cases were extracted (n = 844) and divided into the SIRS group (n = 336 [ESBL-E12.8% (43/336)]) and non-SIRS group (n = 508 [ESBL-E12.6% (64/508)]). In the SIRS ESBL-E group, the initial antibiotics were susceptible in 55.8% (24/43), among which 91.7% (22/24) improved and 8.3% (2/24) deteriorated or died. The initial antibiotics were resistant in 44.2% (19/43), among which 47.4% (9/19) improved with the initial antibiotics, 47.4% (9/19) improved after escalating antibiotics, and 5.3% (1/19) deteriorated or died. In the SIRS group, 14 cases had true bacteremia with ESBL-E. Seven cases were initiated with inappropriate antibiotics; four cases showed improvement before or without antibiotic change and three cases improved after antibiotic escalation. CONCLUSION: Initiation of narrow-spectrum antibiotics in septic UTI with ESBL-E might not deteriorate the clinical outcome if promptly escalated on clinical deterioration or with ESBL-E culture results. Further investigation is warranted to guide judicious use of initial antibiotics.

Cardiac arrest during hemodialysis: a survey of five Japanese hospitals.

AIM: Intraprocedural cardiac arrest is a serious complication among patients receiving hemodialysis. However, the frequency and reaction to these events remain unclear. This study aimed to explore the clinical picture of cardiac arrest during hemodialysis. METHODS: Ten cardiac arrests that had occurred during 217,984 hemodialysis treatments in five Japanese hospitals, between 2008 and 2017, were reviewed. We investigated the underlying disease, vital signs, emergency responses, and outcomes using patient medical records. RESULTS: The cardiac arrest rate ranged from 1.1 to 7.5 per 100,000 hemodialysis sessions. All included cases of cardiac arrest occurred in a hemodialysis unit and had been witnessed and reported by supervising clinicians. The initial rhythm was ventricular fibrillation/ventricular tachycardia in six patients (60%) and pulseless electrical activity/asystole in four patients (40%). Seven (70%) patients showed a return of spontaneous circulation (ROSC), and two (20%) patients were discharged with a cerebral performance category score of 1. There was a statistically significant difference in the ROSC rate (P = 0.048) only in the event of an emergency call. The SpO2 and respiratory rates had not been recorded in six patients. There was no significant difference in ROSC between initial rhythms of ventricular fibrillation/ventricular tachycardia and pulseless electrical activity/asystole. CONCLUSION: We evaluated the frequency of cardiac arrest during hemodialysis. Overall assessment including respiratory status is needed at initiation of hemodialysis. In case of a sudden change in a patient's status, high-quality resuscitation treatment that includes an emergency call can improve prognosis.

Positive clinical risk factors predict a high rate of methicillin-resistant Staphylococcus aureus colonization in emergency department patients.

BACKGROUND: This study was undertaken to determine the rate of methicillin-resistant Staphylococcus aureus (MRSA) colonization predicted by clinical risk factors compared with determination by nasal swab culture and polymerase chain reaction in emergency department patients. METHODS: From November 2009 to March 2011, patients seen in the emergency department were studied prospectively. The risk of MRSA colonization was determined by clinical risk factors, and both surveillance cultures and a polymerase chain reaction assay were performed in each patient. RESULTS: A total of 277 patients was enrolled, and 31.4% (87/277) of patients had a positive surveillance culture or a MRSA polymerase chain reaction assay. The rate of colonization in patients with high-risk factors included the following: past history of colonization/infections, 60.0%; history of previous antibiotic use, 47.2%; more than 30 days hospitalization in the past 3 months, 43.9%; more than 10 days hospitalization in the past 3 months, 41.7%; and a history of hospitalization because of acute illness, 40.0%. CONCLUSION: The prevalence rate of colonization in patients with a high risk of MRSA colonization exceeded 30%. Active surveillance cultures should be considered in patients at high risk for MRSA colonization.
