Evaluation of Bedside Lung Ultrasonography in Diagnosis of Acute Pulmonary Oedema

Background: Pulmonary oedema is one of the major causes of mortality and morbidity. Acute heart failure is the major cause of pulmonary oedema. NT-pro B-type natriuretic peptide has been found to be effective in distinguishing acute pulmonary oedema from other causes of dyspnea in the emergency care setting. But it is costly and time consuming. Bedside lung ultrasonography (LUS) is being considered as noninvasive, radiation-free and easy to perform tool to diagnosis pulmonary oedema. Objective: To determine the role of bedside LUS in diagnosis of patients with acute pulmonary oedema. Methods: This observational cross-sectional study was carried out in ICU, Department of Anaesthesia, Analgesia, Palliative & Intensive Care Medicine, Dhaka Medical College Hospital, Dhaka from August 2018 to October 2019. Ethical approval was sought before conduction of the study. One hundred critically-ill patients with pulmonary oedema, detected by clinical examination & chest X-ray, due to heart failure were included in the study. Routine labs including NT-pro B-type natriuretic peptide level were sent. Bedside LUS was done with a portable ultrasound machine. Data was collected by using a semi-structured data sheet. Observation and Results: The median age was 42 years (IQR 18-66). Among them, 67.71% were male. 90.0% of patients diagnosed as acute pulmonary oedema by NT-pro B-type natriuretic peptide levels findings and 88.5% of patients were diagnosed as acute pulmonary oedema by bedside lung ultrasonography. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of lung ultrasonography findings alone statistically significant as 94.2%, 66.7%, 96.4% & 54.5% and 91.66% respectively in detection of pulmonary oedema. Conclusions: Bed side lung ultrasonography can be an effective adjunct tool for rapid and high diagnostic accuracy for diagnosis of acute pulmonary oedema along with NT pro BNP level in ICU.

Optimized fosfomycin regimens for treating carbapenem-resistant Acinetobacter baumannii in criticallyill patients with varying degrees of renal function.

Fosfomycin has been used to treat carbapenem-resistant Acinetobacter baumannii (CRAB) infections. However, there is insufficient information on dosage adjustment among critically ill patients with renal impairment. This study aims to evaluate the attainment of PK/PD targets for different dosage regimens of CRAB treatment in critically ill patients based on their renal function. Monte Carlo simulations were conducted to assess the probability of achieving time above the minimum inhibitory concentration (T > MIC) of 80% and 100% and to determine the cumulative fraction response (CFR) against institutional MICs. Our results demonstrated that administering fosfomycin 20-24 g/day to individuals with normal renal function (CrCl ≥60 mL/min) achieved the target at a MIC of ≤64 and ≤32 μg/mL during the first 24 h of treatment and at steady state, respectively. Notably, those with renal impairment achieved higher MIC values at a steady state despite dosage reduction. None of the regimens reached the target CFR. Our study suggested that administering fosfomycin at least 20 g/day to those with normal renal function provides sufficient exposure throughout the treatment course when the MIC value is ≤32 μg/mL. Less aggressive dosing regimens are advisable for patients with renal impairment. Additional clinical studies are necessary to verify our suggestions.

Evaluation of knowledge and attitude concerning augmented renal clearance among physicians and clinical pharmacists in Al-Ain, UAE: A cross-sectional study

Background Kidney function assessment is crucial in critical illness patients and is required before administering renally excreted medication, especially antibiotics and antiepileptics. Conventional clinical practice often focuses on renal impairment with low creatinine clearance (CrCl) and overlooks the augmented renal clearance (ARC), which is defined by (CrCl) more than 130 ml/min. This typical demonstration neglects individuals who experience hyperfunctioning kidneys. Among critically ill patients, the prevalence of (ARC) is approximately 20% to 65% of cases. This study aims to evaluate physicians’ and clinical pharmacists’ knowledge about ARC-associated risk factors, antibiotic regimen modification in ARC patients, and attitudes towards ARC workshops and guidelines in Al-Ain, UAE. Methods A cross-sectional, online self-administered survey-based study was designed to achieve this study’s aim. The questionnaire was constructed on profound literature analysis, validated, and piloted. The survey was emailed to physicians and pharmacists working in two hospitals, private and governmental, and distributed through different social media platforms over three months, December 2022—February 2023. Results Of the 92 complete responses (32 clinical pharmacists, 60 physicians), 57 (61.9%), were aware of ARC, but 72 (78%) demonstrated poor knowledge overall. Clinical pharmacists had a higher mean rank of knowledge than the physician’s group. Meanwhile, 70 (76.1%) participants were unaware of the eGFR threshold to determine ARC. There is a noticeable positive attitude toward seeking more information about antibiotic dose adjustment in ARC patients at 85 (92%) of the respondents. Remarkably, only 28 (30.4%) were directly involved with ARC patients’ treatment plans. Conclusion In conclusion, clinical pharmacists showed better knowledge than physicians. However, overall, the participating healthcare providers lacked knowledge about ARC, so a reliable source of information regarding ARC should be utilized. Future research could explore the implementation of professional development workshops for healthcare providers and national guidelines and then assess their impact on patient outcomes.

Interferon-responsive neutrophils and macrophages extricate SARS-CoV-2 Omicron critical patients from the nasty fate of sepsis.

The SARS-CoV-2 Omicron variant is characterized by its high transmissibility, which has caused a worldwide epidemiological event. Yet, it turns ominous once the disease progression degenerates into severe pneumonia and sepsis, presenting a horrendous lethality. To elucidate the alveolar immune or inflammatory landscapes of Omicron critical-ill patients, we performed single-cell RNA-sequencing (scRNA-seq) of bronchoalveolar lavage fluid (BALF) from the patients with critical pneumonia caused by Omicron infection, and analyzed the correlation between the clinical severity scores and different immune cell subpopulations. In the BALF of Omicron critical patients, the alveolar violent myeloid inflammatory environment was determined. ISG15+ neutrophils and CXCL10+ macrophages, both expressed the interferon-stimulated genes (ISGs), were negatively correlated with clinical pulmonary infection score, while septic CST7+ neutrophils and inflammatory VCAN+ macrophages were positively correlated with sequential organ failure assessment. The percentages of ISG15+ neutrophils were associated with more protective alveolar epithelial cells, and may reshape CD4+ T cells to the exhaustive phenotype, thus preventing immune injuries. The CXCL10+ macrophages may promote plasmablast/plasma cell survival and activation as well as the production of specific antibodies. As compared to the previous BALF scRNA-seq data from SARS-CoV-2 wild-type/Alpha critical patients, the subsets of neutrophils and macrophages with pro-inflammatory and immunoregulatory features presented obvious distinctions, suggesting an immune disparity in Omicron variants. Overall, this study provides a BALF single-cell atlas of Omicron critical patients, and suggests that alveolar interferon-responsive neutrophils and macrophages may extricate SARS-CoV-2 Omicron critical patients from the nasty fate of sepsis.

Performance of an Autonomous Sanitary Sterilisation Ultraviolet Machine (ASSUM) on terminal disinfection of surgical theaters and rooms of an intensive-intermediate care unit

Ultraviolet- C (UV-C) light is effective for reducing environmental bioburden in hospitals, and the use of robots to deliver it may be advantageous. To evaluate the feasibility and clinical efficacy of an autonomous programmable UV-C robot in surgical and intensive care unit (ICU) rooms of a tertiary hospital. During ten consecutive months, the device was used in six theatres where cardiac, colorectal and orthopaedic surgeries were performed, and in the rooms previously occupied by patients subjected to contact precautions of a 14-bed ICU. Surgical site infection (SSI) rates of procedures performed in the UV-cleaned theatres were compared with those of the previous year. Incidence in clinical samples of ICU-acquired multiple-drug resistant (MDR) microorganisms was compared with that of the same period of the previous year. An UV-C exposure study done by semi-quantitative dosimeters and a survey of the bioburden on surfaces were carried out. SSI rates in the pre- and post-intervention periods were 8.67% (80/922) and 7.5% (61/813), respectively (p=0.37). Incidence of target microorganisms in clinical samples remained unchanged (38.4 vs. 39.4 per 10,000 patient-days, p=0.94). All the dosimeters exposed to ≤1 meter received ≥500 mJ/cm2. The bacterial load on surfaces decreased after the intervention, particularly in ICU rooms (from 4.57±7.4 CFU to 0.27±0.8 CFU, p<0.0001). Deployment of an UV-C robot in surgical and ICU rooms is feasible, ensures adequate delivery of germicidal UV-C light and reduces the environmental bacterial burden. Rates of surgical site infections or acquisition of MDR in clinical samples of critically-ill patients remained unchanged.

Assessment of Knowledge, Attitude and Practice of Nurses’ Towards Physical Restraints for Critical Ill Patients in Orotta National Referral Hospital

&amp;lt;i&amp;gt;Background&amp;lt;/i&amp;gt;: Physical restraint can be defined as any act that avoids a person&amp;apos;s liberated body change to a position of preference and, or regular evaluation to their body by the application of any technique, attached or adjacent to a person’s body that they cannot manage or remove easily. Inappropriate use of physical restraints may cause patients grave damage. Different studies informed that patients faced to physical restraints pass on due to pneumonia, constipation, and incontinence, as well as circulatory and respiratory problems. Critical care nurses should make correct decisions regarding use of physical restraints if they are to guarantee patient safety by the accountable nurse. &amp;lt;i&amp;gt;Aim&amp;lt;/i&amp;gt;: the intention of this study was to assess nurses’ knowledge, attitude and practice; towards physical restraints use. &amp;lt;i&amp;gt;Method&amp;lt;/i&amp;gt;: study design was a descriptive cross Sectional that used to assess knowledge, attitude and practice of nurses towards physical restraints in Orotta national referral hospital with self-administered questionnaire. Lastly data was analyzed using SPSS version 26. &amp;lt;i&amp;gt;Results&amp;lt;/i&amp;gt;: the study was conducted among 100 nurses. 60% of the respondents were females and the median age of the study participants was 28 (IQR=6) years, with a minimum age of 21 and maximum age of 50yrs. Most of the study participants 31% had age of 25 or less years. Majority of them were diploma level and did not take any physical restraint related training 55% and 84% respectively. Except in recovery (12%) and adult ICU (27%) areas, the number of nurses in medical, surgical and adult was similar (each 20%). More than ninety percent (94%) of the study participants were not aware of the presence of guidelines regarding physical restraint in their work area. &amp;lt;i&amp;gt;Conclusion&amp;lt;/i&amp;gt;: In this current study we concluded that, there was no correlation between knowledge and attitude and also between attitude and practice. But there was correlation between knowledge and practice. Those who have good knowledge can practice well. &amp;lt;i&amp;gt;Nursing implication&amp;lt;/i&amp;gt;: By evaluating the current nurses’ knowledge, attitude and practice, this study will contribute recommendation on the frequent training of nurses on physical restraints and possible avoidance of it or safe practice.

Protocol for the development and validation of a machine-learning based tool for predicting the risk of hypertriglyceridemia in critically-ill patients receiving propofol sedation.

Introduction Propofol is a widely used sedative-hypnotic agent for critically-ill patients requiring invasive mechanical ventilation (IMV). Despite its clinical benefits, propofol is associated with increased risks of hypertriglyceridemia. Early identification of patients at risk for propofol-associated hypertriglyceridemia is crucial for optimizing sedation strategies and preventing adverse outcomes. Machine learning (ML) models offer a promising approach to predict individualized patient risks of propofol-associated hypertriglyceridemia. Methods and analysis We propose the development of a ML model aimed at predicting the risk of propofol-associated hypertriglyceridemia in ICU patients receiving IMV. The study will utilize retrospective data from four Mayo Clinic sites. Nested cross-validation (CV) will be employed, with a 10-fold inner CV loop for model tuning and selection as well as an outer loop using leave-one-site-out CV for external validation. Feature selection will be conducted using Boruta and LASSO-penalized logistic regression. Data preprocessing steps include missing data imputation, feature scaling, and dimensionality reduction techniques. Six ML algorithms will be tuned and evaluated. Bayesian optimization will be used for hyperparameter selection. Global model explainability will be assessed using permutation importance, and local model explainability will be assessed using SHAP. Ethics and dissemination The proposed ML model aims to provide a reliable and interpretable tool for clinicians to predict the risk of propofol-associated hypertriglyceridemia in ICU patients. The final model will be deployed in a web-based clinical risk calculator. The model development process and performance measures obtained during nested cross-validation will be described in a study publication to be disseminated in a peer-reviewed journal. The proposed study has received ethics approval from the Mayo Clinic Institutional Review Board (IRB #23-007416).

Characteristics, Complications, and Outcomes of Critical Illness in Patients with Parkinson Disease.

Adults with Parkinson disease (PD) are hospitalized at higher rates than age-matched controls, and these hospitalizations are associated with significant morbidity. However, little is known about the consequences of critical illness requiring intensive care unit (ICU)-level care in patients with PD. The aim of this study was to define the characteristics and outcomes of adults with PD admitted to the ICU. We performed a retrospective nested case-control study using the Medical Information Mart for Intensive Care IV data set. Adults with PD were identified, and the index ICU admission for these subjects was matched 1:4 with index ICU admissions without a PD diagnosis based on age, sex, comorbidities, illness severity, ICU type, and need for mechanical ventilation. Primary outcomes were in-hospital mortality and discharge location. Secondary outcomes were length of stay and prespecified complications. A total of 630 adults with PD were identified. Patients with PD were older and were more likely to be male, have more comorbidities, and have higher illness severity at presentation. A matched analysis revealed adults with PD did not have a significant difference in in-hospital mortality but were more likely to be discharged to ahigher level of care. Adults with PD had longer hospital lengths of stay and increased odds of delirium, pressure ulcers, and ileus. During critical illness, patients with PD are at increased risk for longer hospital lengths of stay and complications and require a higher level of care at discharge than matched controls. These findings reveal targets for interventions to improve outcomes for patients with PD and may inform discussions about goals of care in this population.

A multilayered infection control intervention on carbapenem-resistant Acinetobacter baumannii acquisition: An interrupted time series

Carbapenem-resistant Acinetobacter baumannii (CRAB) causes life-threating hospital-acquired. Due to a limited number of Intensive-Care-Unit (ICU) beds, these patients are often treated in high-dependency (HD) non-ICUs within internal-medicine wards (IMW) in Israel. We aimed to assess the effectiveness of a multilayered infection-control intervention on CRAB infection rate in IMWs, especially in its HD non-ICUs with ongoing CRAB transmission. A quasi-experimental, before-and-after, interrupted time-series study with control outcomes. We conducted a multilayered intervention over 3.5years, which included 4 phases: (1) Pre intervention; (2) Interventionintroduction: introduced enhanced environment cleaning; (3) Intervention phase 1: introduced active surveillance; (4) Intervention phase 2: introduced CRAB-positive patient cohorting, in addition to previous ongoing measures taken. CRAB was isolated from 204 patients aged 69.8y/o±15.86y, 59.8% male, 34.3% had CRAB-positive clinical samples. Mean hospital length-of-stay was 30.5days, with a 30-day postdischarge mortality rate of 55.9%. Mean CRAB clinical cases decreased from 0.89 in preintervention to 0.11 at the end of phase 2, with a change in slope and level after the intervention of P=.02 (CI: -0.204to -0.040) and P=.004 (CI: -0.013 to -0.003), respectively. This intervention, including enhanced environment cleaning, active surveillance, and patient cohorting, successfully reduced CRAB acquisition in IMWs and their HD non-ICUs.

Undergraduate Student Nurses' Satisfaction, Self-confidence, and Perception of High-fidelity Simulation-based Learning on Critically-ill Patients.

Replicating critical care practice settings in high-fidelity simulation (HFS) provides more learning opportunities to develop competencies, improve self-confidence, and learner satisfaction in a safe environment. Simulation is increasingly adopted globally as an alternative teaching strategy. Yet, data on the HFS experience of Filipino undergraduate nursing students is limited. This study describes the satisfaction, self-confidence, and perception of undergraduate nursing students on the use of HFS-based learning on critically-ill adult and pediatric patients requiring advanced life support (ALS). A quantitative, descriptive, correlational study was conducted using purposive sampling on all fourth-year BS Nursing students enrolled in Critical Care Nursing course in a state university. Data were collected through an online survey on demographic data, and the students' perceptions towards high-fidelity simulation-based learning (SBL) using three tools, namely: Simulation Design Scale, Educational Practices Questionnaire, and Student Satisfaction and Self-confidence in Learning. T-test and ANOVA were used to compare the means of the variables. Bivariate analysis (Pearson's product-moment correlation) was performed to find the relationship between variables. A total of 86 students participated in the survey. Overall, the students were highly satisfied with the simulation experience (4.46 out of 5.0, SD=0.47), and had high ratings of self-confidence in SBL (4.44 out of 5.0, SD=0.42). Overall satisfaction level was positively related to student's perception on simulation design (r=0.61, p<0.01) and educational practices (r=0.59, p<0.01). Similarly, the students' overall self-confidence with SBL was also positively correlated with their perceptions of the simulation design (r=0.32, p<0.01), and educational practices (r=0.34, p<0.01). Effective use of technology through HFS-based learning is useful in increasing satisfaction and self-confidence of Filipino undergraduate nursing students in caring for critically-ill patients needing ALS. Educators must highly consider all parameters of simulation design and educational practices in planning and implementing HFS-based learning to achieve meaningful learner experience.

Prevalence of the Cefazolin Inoculum Effect (CzIE) in Nasal Colonizing Methicillin-Susceptible Staphylococcus aureus in Patients from Intensive Care Units in Colombia and Use of a Modified Rapid Nitrocefin Test for Detection.

The cefazolin inoculum effect (CzIE) has been associated with poor clinical outcomes in patients with MSSA infections. We aimed to investigate the point prevalence of the CzIE among nasal colonizing MSSA isolates from ICU patients in a multicenter study in Colombia (2019-2023). Patients underwent nasal swabs to assess for S. aureus colonization on admission to the ICU and some individuals had follow-up swabs. We performed cefazolin MIC by broth-microdilution using standard and high-inoculum and developed a modified nitrocefin-based rapid test to detect the CzIE. Whole genome sequencing was carried out to characterize BlaZ types and allotypes, phylogenomics and Agr-typing. All swabs were subjected to 16S-rRNA metabarcoding sequencing to evaluate microbiome characteristics associated with the CzIE. A total of 352 patients were included; 46/352 (13%) patients were colonized with S. aureus; 22% (10/46) and 78% (36/46) with MRSA and MSSA, respectively. Among 36 patients that contributed with 43 MSSA colonizing isolates, 21/36 (58%) had MSSA exhibiting the CzIE. BlaZ type A and BlaZ-2 were the predominant type and allotype in 56% and 52%, respectively. MSSA belonging to CC30 were highly associated with the CzIE and SNP analyses supported transmission of MSSA exhibiting the CzIE among some patients of the same unit. The modified nitrocefin rapid test had 100%, 94.4% and 97.7% sensitivity, specificity and accuracy, respectively. We found a high prevalence point prevalence of the CzIE in MSSA colonizing the nares of critically-ill patients in Colombia. A modified rapid test was highly accurate in detecting the CzIE in this patient population.

Assessment of Energy Consumption Patterns and Validation of Predictive Equations among ICU Patients at Muhimbili National Hospital in Dar es Salaam, Tanzania

Background: Nutritional support in critically-ill patients is one of the most important parameters guarding the prognosis and influencing morbidity and mortality in these patients, owing to that fact, accurate measurement of the resting energy expenditure using Indirect calorimetry is recommended by guidelines as a gold standard. But due to lack of resources and other technicalities predictive equations are conveniently used as surrogates. Aims: This study was intended to examine the extent of malnutrition, poor nutrition support practices and to validate the common used predictive equations in critically-ill patients in our setting. Methodology: A hospital-based descriptive cross-sectional study was conducted on consecutively sampled 110 mechanically ventilated ICU patients at Muhimbili National Hospital Mloganzila. Anthropometric measurements, duration of stay in ICU, Temperature and Minute Volumes were recorded so as to estimate resting energy expenditure, REE from different predictive equations. Using Indirect Calorimetry Module patient’s REE was measured and recorded then a statistical data analyzed using SPSS software version 23. Results: The prevalence of poor nutritional support was 69%; underfeeding and overfeeding were observed in 41.8% and 27.3% of all participants respectively. Prevalence of malnutrition was 51.8%; underweight and overweight were found to be in 29.1% and 22.7% of all participants respectively. The accuracy of predictive equation in ±10% difference was 30%, 45.5%, 46.4% and 68.2% in HB, MSJ, ESPEN and PENN respectively. Conclusion and Recommendation: Malnutrition and Poor Nutritional support are common problems in ICU. Predictive equations have poor accuracy and validity in comparison to indirect calorimetry. Penn State Equation was the most accurate and with the highest agreement with IC.

Nutritional Support for ICU Patients Receiving Extracorporeal Membrane Oxygenation Therapy: A Meta-Analysis

Abstract Background ECMO constitutes a mechanical technique that provides extracorporeal gas exchange or/and circulatory support for patients with refractory life-threatening pulmonary or/ and cardiac failure. There is infrequent evidence regarding the optimal nutritional management and related clinical outcomes for adult critically-ill patients receiving ECMO. Objective This study was conducted to evaluate the effect of nutritional intervention on clinical outcomes in adult critically ill patients receiving Extracorporeal Membrane Oxygenation Therapy. Methodology Advanced search was conducted in Medline, PubMed, google scholar and the Egyptian Knowledge Bank for cohort studies that were published in English until September 2020. Inclusion Criteria cohort studies which assess nutrition support in adult critically-ill patients receiving ECMO therapy, and include at least one of these outcomes a) 28-day mortality, b) length of ICU stay, C) duration of mechanical ventilation and d) incidence of infection. Exclusion Criteria duplicate reports, Abstracts, case reports, case series, review articles, editorials and clinical guidelines. In addition, studies with unavailable full text or studies with different outcomes were excluded. Results 7 studies with a total number of 2358 patients were included in the meta-analysis. Estimates and their 95% confidence intervals (CI) were calculated, then pooled for analysis. Nutrition support in adult critically ill patients receiving ECMO was significantly related to 28-day mortality ( 95% CI 0.428 = 0.329–0.527; p &amp;lt; 0.001), increased ICU length of stay ( 95% CI 29.512 (22.930–36.095), and P value &amp;lt; 0.001), duration of mechanical ventilation (95% CI 17.985 = 4.682–31.288; p &amp;lt; 0.008) and incidence of infection ( 95% CI 0.105 ( 0.066 – 0.144), and P value &amp;lt; 0.001). Conclusion The study indicates positive association between effective nutrition support and clinical outcomes for adult critically-ill patients receiving ECMO therapy.

Feasibility of Short-Term Use of Ivabradine in Critical Ill Patients Who Have Atrial Fibrillation and Tachycardia.

Ivabradine is approved for heart rate reduction in patients with stable symptomatic heart failure (HF). The United States Food and Drug Administration and Taiwan Central Health Insurance Agency approved the use of ivabradine for patients with chronic stable HF with sinus rhythm, but it has not yet been approved for patients with acute decompensated HF or with atrial fibrillation (AF). To investigate whether short-term ivabradine use is feasible in critically ill patients with AF and rapid ventricular response (RVR). This study retrospectively analyzed 23 patients admitted to an intensive care unit with acute HF and AF-RVR who received ivabradine. All patients initially received a slow IV of amiodarone. Other medications for HF were prescribed according to current HF guidelines. The time taken for ivabradine to reduce HR to 80 beats per minute, referred to as "Time to 80," was measured in each patient. Overall, 69.6 % (16/23) of the patients had New York Heart Association functional class IV HF. In addition, 60.9% (14/23) of the patients required endotracheal intubation and ventilatory support, with more than half receiving vasopressor treatment to manage hypotension. Five patients died during the study period. The surviving patients had a significantly shorter "Time to 80" compared to those who did not survive (p = 0.037). Adding ivabradine to standard treatment might be feasible for critically ill patients with AF and tachycardia. The finding that surviving patients had a shorter "Time to 80" duration than those who did not survive may have clinical implications. However, further investigations are needed to assess its clinical utility.

Effect of Swedish Abdominal Massage on Gastrointestinal Outcomes of Critical Ill Patients

[Artículo traducido] Predicción de reacciones adversas a medicamentos en pacientes geriátricos ingresados en unidades de cuidados intensivos

IntroductionIntensive Care Units (ICUs) pose challenges in managing critically-ill patients with polypharmacy, potentially leading to Adverse Drug Reactions (ADRs), particularly in the elderly. ObjectiveTo evaluate whether the severity and clinical prognosis scores used in ICUs correlate with the prediction of ADRs in aged patients admitted to an ICU. MethodsA cohort study was conducted in a Brazilian University Hospital ICU. APACHE II and SAPS 3 assessed clinical prognosis, while GerontoNet ADR Risk Score and BADRI evaluated ADR risk at ICU admission. Severity of the patients' clinical conditions was evaluated daily based on the SOFA score. Adverse Drug Reaction (ADR) screening was performed daily through the identification of ADR triggers. Results1295 triggers were identified (median 30 per patient, IQR = 28), with 15 suspected ADRs. No correlation was observed between patient severity and ADRs at admission (p=0.26), during hospitalization (p=0.91), or at follow-up (p=0.77). There was also no association between death and ADRs (p=0.28) or worse prognosis and ADRs (p>0.05). Higher BADRI scores correlated with more ADRs (p=0.001). ConclusionsThe data suggest that employing the severity and clinical prognosis scores used in Intensive Care Units is not sufficient to direct active pharmacovigilance efforts, which are therefore indicated for critically ill patients.

Comprehensive analysis of clinical outcomes, infectious complications and microbiological data in newly diagnosed multiple myeloma patients: a retrospective observational study of 92 subjects

Patients with multiple myeloma (MM) have an increased risk of sepsis due to underlying disease- and treatment-related immunosuppression. However, data on sepsis incidence, causative pathogens, and impact on outcomes in newly diagnosed MM (NDMM) are limited. We conducted a retrospective observational study of 92 NDMM patients who developed sepsis between 2022 and 2023 at a tertiary care center in Italy. Patient characteristics, sepsis criteria [Quick Sequential Organ Failure Assessment, Systemic Inflammatory Response Syndrome (SIRS)], microbiology results, and associations with progression-free survival (PFS) were analyzed. In this cohort of 92 critically-ill patients, pathogenic organisms were identified via microbiological culture in 74 cases. However, among the remaining 18 culture-negative patients, 9 exhibited a SIRS score of 2 and another 9 had a SIRS score of 4, suggestive of a clinical presentation consistent with sepsis despite negative cultures. Common comorbidities included renal failure (60%), anemia (71%), and bone disease (83%). Gram-negative (28%) and Gram-positive (23%) bacteria were frequent causative organisms, along with fungi (20%). Cox Univariate analyses for PFS showed statically significant HR in patients with albumin ≥ 3.5 vs < 3.5 (HR = 5.04, p < 0.001), Karnofsky performance status ≥ 80 vs < 80 (HR = 2.01, p = 0.002), and early-stage vs late-stage disease by International Staging System (HR = 4.76 and HR = 12.52, both p < 0.001) and Revised International Staging System (R-ISS III vs R-ISS I, HR = 7.38, p < 0.001). Sepsis is common in NDMM and associated with poor outcomes. Risk stratification incorporating sepsis severity, comorbidities, and disease stage may help guide preventive strategies and optimize MM management.

Using patient and care partner experiences to confirm outcomes of relevance for inclusion in a core outcome set for trials of physical rehabilitation in critical illness: A qualitative interview study

BackgroundIncorporating the perspectives of patients and care partners is crucial in the development of core outcome sets. One effective approach for achieving this involvement is by seeking input to refine the outcomes for consensus.The objectives of the study were to: i) to determine patient and care partner views on outcomes that should be measured in trials of physical rehabilitation interventions across the critical illness recovery continuum; (ii) to map these views with a pre-established list of thirty outcomes for potential inclusion in a core outcome set for these trials; and (iii) to identify any new outcomes that could be considered for inclusion. MethodsA qualitative semistructured telephone interview study was conducted with a convenience sample of post–critical illness patients and care partners, as part of core outcome set development work. Anonymised interview transcripts were analysed using a framework approach, and exemplary narrative quotes from participants were reported used to illustrate outcome reporting. FindingsFourteen participants were recruited (male:female ratio = 8:6, age range [minimum–maximum]: 50–80 years, 13 former patients, one spouse). Time since intensive care unit discharge ranged from less than 1 year to 10 years at the time of interview. Participants described a range of outcomes that could be measured in trials of physical rehabilitation after critical illness that mapped closely with the pre-established list. No new outcomes were introduced by participants during the interviews. Experiences described by participants commonly reflected outcomes related to physical ability and performance, functional level, activities of daily living, and emotional and mental wellbeing. Participants spoke to how the different outcomes directly impacted their day-to-day lives and highlighted their priorities centred around resumption of tasks and activities that had value to them at personal, functional, and societal level. ConclusionQualitative interviews confirmed the relevance of existing outcomes for potential inclusion in a core outcome set for trials of physical rehabilitation interventions across the critical illness recovery continuum. The added significance of our findings is to provide real-world meaning to these outcomes. RegistrationCOMET Initiative, ID288, https://www.comet-initiative.org/studies/details/288.
