[PMID: 38693271 PMCID: PMC11063212 DOI: 10.1038/s41598-024-58199-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 03/26/2024] [Indexed: 05/03/2024] Open
Abstract
This study aims to investigate the effects of intraoral cold water spray on thirst, frequency of oral care and postoperative period pain at surgical incision site in patients having abdominal surgery. The study was carried out as a randomized controlled trial, registered under Clinical Trial Number: NCT05940818. The study involved 110 participants, divided equally into two groups (n = 55): the experimental group and the control group. Data were collected using patient information form, NRS, Intensive Care Oral Care Frequency Assessment Scale (ICOCFAS) and Visual Analog Scale (VAS). The severity of thirst at 1st, 8th, 16th h of post-operative period (p < 0.01) and the frequency of oral care application at 16th h were statistically significantly decreased in the experimental group when compared to the control group (p < 0.01).There wasn't statistically significant difference between the patients in the experimental and control groups in terms of pain at surgical incision site (p > 0.05). The patient's thirst and need for frequent oral care in the postoperative period were reduced by the application of a cold water spray. In patients undergoing abdominal surgery, the use of cold water spray application may be recommended to reduce thirst and the need for frequency of oral care application.

Abstract
OBJECTIVE To describe and characterize a cohort of octogenarian patients admitted to the ICU of the University Central Hospital of Asturias (HUCA). DESIGN Retrospective, observational and descriptive study of 14 months' duration. SETTING Cardiac and Medical intensive care units (ICU) of the HUCA (Oviedo). PARTICIPANTS Patients over 80 years old who were admitted to the ICU for more than 24 h. INTERVENTIONS None. MAIN VARIABLES OF INTEREST Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality. RESULTS The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p = 0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p = <0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR = 0,18; 95% CI (0,062-0,527; p = 0,002). CONCLUSIONS The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty.

Abstract
INTRODUCTION Intensive care units (ICUs) pose challenges in managing critically ill patients with polypharmacy, potentially leading to adverse drug reactions (ADRs), particularly in the elderly. OBJECTIVE To evaluate whether the severity and clinical prognosis scores used in ICUs correlate with the prediction of ADRs in aged patients admitted to an ICU. METHODS A 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. ADR screening was performed daily through the identification of ADR triggers. RESULTS 1295 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). CONCLUSIONS These data suggest that employing the severity and clinical prognosis scores used in ICUs is not sufficient to direct active pharmacovigilance efforts, which are therefore indicated for critically ill patients.

Abstract
In this editorial, we comment on the article by Wang and Long, published in a recent issue of the World Journal of Clinical Cases. The article addresses the challenge of predicting intensive care unit-acquired weakness (ICUAW), a neuromuscular disorder affecting critically ill patients, by employing a novel processing strategy based on repeated machine learning. The editorial presents a dataset comprising clinical, demographic, and laboratory variables from intensive care unit (ICU) patients and employs a multilayer perceptron neural network model to predict ICUAW. The authors also performed a feature importance analysis to identify the most relevant risk factors for ICUAW. This editorial contributes to the growing body of literature on predictive modeling in critical care, offering insights into the potential of machine learning approaches to improve patient outcomes and guide clinical decision-making in the ICU setting.

Abstract
BACKGROUND There are few thorough studies assessing predictors of severe encephalitis, despite the poor prognosis and high mortality associated with severe encephalitis. The study aims to evaluate the clinical predictors of mortality and poor outcomes at hospital discharge in patients with severe infectious encephalitis in intensive care units. METHOD In two Chinese hospitals, a retrospective cohort study comprising 209 patients in intensive care units suffering from severe infectious encephalitis was carried out. Univariate and multivariate logistic regression analyses were used to identify the factors predicting mortality in all patients and poor outcomes in all survivors with severe infectious encephalitis. RESULTS In our cohort of 209 patients with severe encephalitis, 22 patients died, yielding a mortality rate of 10.5%. Cerebrospinal fluid pressure ≥ 400mmH2O (OR = 7.43), abnormal imaging (OR = 3.51), abnormal electroencephalogram (OR = 7.14), and number of rescues (OR = 1.12) were significantly associated with an increased risk of mortality in severe infectious encephalitis patients. Among the 187 survivors, 122 (65.2%) had favorable outcomes, defined as the modified Rankine Scale (mRS) score (0 ~ 3), and 65(34.8%) had poor outcomes (mRS scores 4 ~ 5). Age (OR = 1.02), number of rescues (OR = 1.43), and tubercular infection (OR = 10.77) were independent factors associated with poor outcomes at discharge in all survivors with severe infectious encephalitis. CONCLUSIONS Multiple clinical, radiologic, and electrophysiological variables are independent predictive indicators for mortality and poor outcomes in patients with severe encephalitis in intensive care units. Identifying these outcome predictors early in patients with severe encephalitis may enable the implementation of appropriate medical treatment and help reduce mortality rates.

Abstract
BACKGROUND Globally, prematurity is the primary factor behind the mortality of children under the age of 5 years, resulting in approximately 1 million children dying annually. The World Health Organization (WHO) recommends Skin-to-Skin Contact (SSC) as part of routine care for preterm infants. Evidence shows that SSC reduces mortality, possibly by improving thermoregulation, facilitating the earlier initiation of breastfeeding and reducing the risk of nosocomial infection. An educational program for implementing SSC has been demonstrated to enhance the knowledge and practice of parents and nurses in intensive care units. This study, the first of its kind in the North West Province (NWP), aims to identify the essential components of an educational program for implementing SSC for premature infants in intensive care units. OBJECTIVE This paper presents an integrative literature review that critically synthesizes research-based literature on essential components of an educational program for implementing SSC for preterm infants in intensive care units. METHODS A comprehensive search of electronic databases, such as CINAHL, MEDLINE, PsycINFO, ProQuest and Health Source: Nursing/Academic Edition and Health Source-Consumer Edition, was conducted using different keywords and references lists from the bibliography. RESULTS Twelve articles relevant to this review were identified, read and synthesized to answer the research question. Three essential components emerged from the findings of this review, namely (1) the necessity of policy and role players for implementing SSC, (2) the availability of education and training, and (3) counseling and support for parents of preterm infants. CONCLUSIONS The outcomes of this study have the potential to facilitate the implementation and expansion of SSC in intensive care units. This could aid program implementers, policymakers, and researchers to implement and scale up this important tool in intensive care units.

Abstract
BACKGROUND Health status, including cognitive functioning before critical illness, is associated with long-term outcomes in intensive care unit survivors. Premorbid data are therefore of importance in longitudinal studies. Few patients can self-report at intensive care admission. Consequently, proxy assessments of patients' health status are used. However, it remains unclear how accurately proxies can report on an intensive care patient's cognitive status. OBJECTIVES The aim of this study was to examine the agreement between patient- and proxy-reporting of the Cognitive Failures Questionnaire and to compare the agreement between proxy reports using the latter questionnaire and the Informant Questionnaire of Cognitive Decline in the Elderly as a reference. METHODS The present cohort study is part of a longitudinal multicentre study collecting both patient and proxy data using questionnaires and clinical data from medical records during intensive care unit stays. Agreement on patient and proxy pairs was examined using intraclass correlation coefficient (ICC), Spearman's correlation, percentage agreement, and Gwet's AC1 statistics. Agreement between the proxy-reported questionnaires was examined using percentage agreement and Gwet's AC1 statistics. RESULTS In total, we collected 99 pairs of patient-proxy assessments and 158 proxy-proxy assessments. The ICC for the sum scores revealed moderate agreement (n = 99; ICC = 0.59; 99% confidence interval [CI]: [0.30-0.76]) between patient and proxy. Agreement on items was poor (AC1 = 0.13; 99% CI: [0.01-0.24]) to moderate (AC1 = 0.55; 99% CI: [0.43-0.68]). Agreement using cut-off scores (>43) to indicate cognitive impairment was very good (89.9%, AC1 = 0.87; 99% CI: [0.79-0.95]). Agreement between the proxy-reported Cognitive Failures Questionnaire (>43) and the reference questionnaire (≥3.5) was also very good (n = 158; 85%, AC1 = 0.82; 99% CI: [0.74-0.90]). CONCLUSIONS Proxy assessments of the Cognitive Failures Questionnaire (>43) may be used to indicate cognitive impairment if patients are unable to self-report. Agreement was high between the two questionnaires determined by proxies, showing that these can be used interchangeably to assess cognitive functioning if proxy reporting is needed.

Abstract
BACKGROUND The influence of socioeconomic deprivation on health inequalities is established, but its effect on critically ill patients remains unclear, due to inconsistent definitions in previous studies. METHODS Prospective multicenter cohort study conducted from March to June 2018 in eight ICUs in the Greater Paris area. All admitted patients aged ≥ 18 years were enrolled. Socioeconomic phenotypes were identified using hierarchical clustering, based on education, health insurance, income, and housing. Association of phenotypes with 180-day mortality was assessed using Cox proportional hazards models. RESULTS A total of 1,748 patients were included. Median age was 62.9 [47.4-74.5] years, 654 (37.4%) patients were female, and median SOFA score was 3 [1-6]. Study population was clustered in five phenotypes with increasing socioeconomic deprivation. Patients from phenotype A (n = 958/1,748, 54.8%) were without socioeconomic deprivation, patients from phenotype B (n = 273/1,748, 15.6%) had only lower education levels, phenotype C patients (n = 117/1,748, 6.7%) had a cumulative burden of 1[1-2] deprivations and all had housing deprivation, phenotype D patients had 2 [1-2] deprivations, all of them with income deprivation, and phenotype E patients (n = 93/1,748, 5.3%) included patients with 3 [2-4] deprivations and included all patients with health insurance deprivation. Patients from phenotypes D and E were younger, had fewer comorbidities, more alcohol and opiate use, and were more frequently admitted due to self-harm diagnoses. Patients from phenotype C (predominant housing deprivation), were more frequently admitted with diagnoses related to chronic respiratory diseases and received more non-invasive positive pressure ventilation. Following adjustment for age, sex, alcohol and opiate use, socioeconomic phenotypes were not associated with increased 180-day mortality: phenotype A (reference); phenotype B (hazard ratio [HR], 0.85; 95% confidence interval CI 0.65-1.12); phenotype C (HR, 0.56; 95% CI 0.34-0.93); phenotype D (HR, 1.09; 95% CI 0.78-1.51); phenotype E (HR, 1.20; 95% CI 0.73-1.96). CONCLUSIONS In a universal health care system, the most deprived socioeconomic phenotypes were not associated with increased 180-day mortality. The most disadvantaged populations exhibit distinct characteristics and medical conditions that may be addressed through targeted public health interventions.

Abstract
BACKGROUND Goal-concordant care in intensive care is care that aligns with the patient's expressed goals, values, preferences and beliefs. Communication and shared decision-making are key to ensuring goal-concordant care. AIMS The aims of his study were to explore (i) critical care clinicians' perspectives on how patient goals of care were communicated between clinicians, patients, and family in the intensive care unit; (ii) critical care nurses' role in this process; and (iii) how goals of care were used to guide care. METHOD Sequential two-phase qualitative descriptive design. Data were collected from February to June 2022 in a level-3 intensive care unit in a private hospital in Melbourne, Australia. In Phase One, individual interviews were conducted with critical care nurse participants (n = 11). In Phase Two, the findings were presented to senior clinical leaders (n = 2) to build a more comprehensive understanding. Data were analysed using Braun and Clarke's six step reflexive thematic analysis. FINDINGS There was poor consensus on the term 'goals of care', with some participants referring to daily treatment goals or treatment limitations and others to patients' wishes and expectations beyond the ICU. Critical care nurses perceived themselves as information brokers and patient advocates responsible for ensuring patient goals of care were respected, but engaging in goals-of-care conversations was challenging. A lack of role clarity, poor team communication, and inadequate processes to communicate patient goals impeded goal-concordant care. Senior clinical leaders affirmed these views, emphasising the need to utilise critical care nurses' insight for practical solutions to improve patient care. CONCLUSIONS Clarity in both, the term 'goals of care' and the critical care nurses' role in these conversations, are the essential first steps to ensuring patients' values, preferences, and beliefs to guide shared-decision-making and goal-concordant care. Improved verbal and written communication that is inclusive of all members of the treating team is key to addressing these issues.

Risk factors predicting the need for intensive care unit admission within forty-eight hours of emergency department presentation: A case-control study. Aust Crit Care 2024:S1036-7314(24)00028-6.

Abstract
BACKGROUND Patients admitted from the emergency department to the wards, who progress to a critically unwell state, may require expeditious admission to the intensive care unit. It can be argued that earlier recognition of such patients, to facilitate prompt transfer to intensive care, could be linked to more favourable clinical outcomes. Nevertheless, this can be clinically challenging, and there are currently no established evidence-based methods for predicting the need for intensive care in the future. OBJECTIVES We aimed to analyse the emergency department data to describe the characteristics of patients who required an intensive care admission within 48 h of presentation. Secondly, we planned to test the feasibility of using this data to identify the associated risk factors for developing a predictive model. METHODS We designed a retrospective case-control study. Cases were patients admitted to intensive care within 48 h of their emergency department presentation. Controls were patients who did not need an intensive care admission. Groups were matched based on age, gender, admission calendar month, and diagnosis. To identify the associated variables, we used a conditional logistic regression model. RESULTS Compared to controls, cases were more likely to be obese, and smokers and had a higher prevalence of cardiovascular (39 [35.1%] vs 20 [18%], p = 0.004) and respiratory diagnoses (45 [40.5%] vs 25 [22.5%], p = 0.004). They received more medical emergency team reviews (53 [47.8%] vs 24 [21.6%], p < 0.001), and more patients had an acute resuscitation plan (31 [27.9%] vs 15 [13.5%], p = 0.008). The predictive model showed that having acute resuscitation plans, cardiovascular and respiratory diagnoses, and receiving medical emergency team reviews were strongly associated with having an intensive care admission within 48 h of presentation. CONCLUSIONS Our study used emergency department data to provide a detailed description of patients who had an intensive care unit admission within 48 h of their presentation. It demonstrated the feasibility of using such data to identify the associated risk factors to develop a predictive model.

Abstract
BACKGROUND The increase in intensive care unit (ICU) capacity compelled by the COVID-19 pandemic required the rapid deployment of non-critical-care registered nurses to the ICU setting. The upskill training needed to prepare these registered nurses for deployment was rapidly assembled due to the limited timeframe associated with the escalating pandemic. Scoping the literature to identify the content, structure, and effectiveness of the upskill education provided is necessary to identify lessons learnt during the COVID-19 pandemic response so that they may guide workforce preparation for future surge planning. AIM The aim of this scoping review was to map the literature to identify the available information regarding upskill training and preparedness of non-critical-care registered nurses deployed to the ICU during the COVID-19 pandemic. METHODS This scoping review was conducted in accordance with JBI methodology. A protocol outlined the review questions and used the participants, concept, and context framework to define the inclusion and exclusion criteria. A search of healthcare databases MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCO), Cochrane, and Scopus was supplemented with a grey literature search via Google. RESULTS Screening and review found 32 manuscripts that met the inclusion criterion for examination. Analysis revealed variation in duration of programs, theoretical versus practical content, face-to-face or online mode of delivery, and duration of preparation time at the bedside in the ICU setting. Data on contributors to preparedness for deployment were sparse but included training, support, peer education, buddy time, and clarity around responsibilities and communication. DISCUSSION Evaluation of upskill education was mostly limited to post-training surveys. Few studies explored the preparedness of deployed registered nurses as an outcome of their upskill training or described measures of effectiveness of ICU deployment. CONCLUSION There is limited evidence describing preparedness of non-critical-care registered nurses on deployment to the ICU. Further research is needed to identify what elements of upskill education led to preparedness and effective deployment to the ICU setting.

Abstract
Aim and background Optimal feeding strategy for critically ill patients of intensive care unit (ICU) is often a matter of debate as patients admitted to ICU are highly catabolic and reduction in muscle mass is very common. We aimed at early achievement of nutritional goals in preventing skeletal muscle breakdown and improving clinical outcomes among critically ill patients with high risk of malnutrition. Materials and methods Nutrition risk in the critically ill (mNUTRIC) Score was used to identify the risk of malnutrition within 24 hours of admission. Quadriceps muscle mass index was measured within 24 hours of admission to ICU and repeated on 7th day. Enteral feeding was monitored by the nutrition expert as part of routine patient care and clinical outcomes were monitored. Results A total of 287 patients admitted in ICU were screened for malnutrition and 60 (20.9%) of them had high score (>5). There was no statistically significant reduction in the quadriceps muscle mass index (p < 0.05) (t = 0.601) measured within 24 hours of admission and on the 7th day of ICU stay, signifying that the nutritional prescription and monitoring may be useful in preserving the muscle mass. This study did not find statistically significant association between the high mNUTRIC score on admission and the clinical outcomes, such as 28 days mortality, incidence of pressure ulcers, length of ICU stay, and hospital-acquired infection (p > 0.05). Conclusion Early initiation and maintenance of enteral nutrition is essential for meeting target calories and protein requirements. It may help to preserve muscle mass in critically ill patients who are otherwise at high risk of malnutrition. How to cite this article Sharon T, Nayak SG, Shanbhag V, Hebbar S.

Abstract
Traumatic brain injury is a leading cause of death and disability worldwide. Interventions that mitigate secondary brain injury have the potential to improve outcomes for patients and reduce the impact on communities and society. Increased circulating catecholamines are associated with worse outcomes and there are supportive animal data and indications in human studies of benefit from beta-blockade after severe traumatic brain injury. Here, we present the protocol for a dose-finding study using esmolol in adults commenced within 24 h of severe traumatic brain injury. Esmolol has practical advantages and theoretical benefits as a neuroprotective agent in this setting, but these must be balanced against the known risk of secondary injury from hypotension. The aim of this study is to determine a dose schedule for esmolol, using the continual reassessment method, that combines a clinically significant reduction in heart rate as a surrogate for catecholamine drive with maintenance of cerebral perfusion pressure. The maximum tolerated dosing schedule for esmolol can then be tested for patient benefit in subsequent randomized controlled trials.Trial registration ISRCTN, ISRCTN11038397, registered retrospectively 07/01/2021 https://www.isrctn.com/ISRCTN11038397.

[PMID: 38681793 PMCID: PMC11043633 DOI: 10.1016/j.jointm.2023.09.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Revised: 09/17/2023] [Accepted: 09/27/2023] [Indexed: 05/01/2024]
Abstract
Background Prolonged length of stay (LOS) of sepsis can drain a hospital's material and human resources. This study investigated the correlations between T helper type 17 (Th17) and regulatory T (Treg) balance with LOS in sepsis. Methods A prospective clinical observational study was designed in Changhai Hospital affiliated to Naval Medical University in Shanghai, China, from January to October 2020. The patients diagnosed with sepsis and who met the inclusion and exclusion criteria were recruited and whether the levels of cytokines, procalcitonin, subtypes, and biomarkers of T cells in the peripheral blood were detected. We analyzed the correlation between these and LOS. Results Sixty septic patients were classified into two groups according to whether their intensive care unit (ICU) stay exceeded 14 days. The patients with LOS ≥14 days were older ([72.6±7.5] years vs. [63.3±10.4] years, P=0.015) and had higher Sequential Organ Failure Assessment (SOFA) (median [interquartile range]: 6.5 [5.0-11.0] vs. 4.0 [3.0-6.0], P=0.001) and higher Acute Physiology and Chronic Health Evaluation (APACHE) II scores (16.0 [13.0-21.0] vs. 8.5 [7.0-14.0], P=0.001). There was no difference in other demographic characteristics and cytokines, interleukin-6, tumor necrosis factor-α, and interleukin-10 between the two groups. The Th17/Treg ratio of sepsis with LOS <14 days was considerably lower (0.48 [0.38-0.56] vs. 0.69 [0.51-0.98], P=0.001). For patients with LOS ≥14 days, the area under the receiver operating characteristic curve for the Th17/Treg ratio was 0.766. It improved to 0.840 and 0.850 when combined with the SOFA and APACHE II scores, respectively. Conclusions The Th17/Treg ratio was proportional to septic severity and can be used as a potential predictor of ICU stay in sepsis, presenting a new option for ICU practitioners to better care for patients with sepsis.

Unfinished nursing care in intensive care units and the mediating role of the association between nurse working environment, and quality of care and nurses' wellbeing. Intensive Crit Care Nurs 2024; 81:103596. [PMID: 38043435 DOI: 10.1016/j.iccn.2023.103596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 11/13/2023] [Accepted: 11/17/2023] [Indexed: 12/05/2023]
Abstract
OBJECTIVES Unfinished care refers to the situation in which nurses are forced to delay or omit necessary nursing care. The objectives was: 1) to measure the prevalence of unfinished nursing care in intensive care units during the COVID-19 pandemic; 2) to examine whether unfinished nursing care has a mediating role in the relationship between nurse working environment and nurse-perceived quality of care and risk of burnout among nurses. DESIGN A national cross-sectional survey. SETTING Seventy-five intensive care units in Belgium (December 2021 to February 2022). MAIN OUTCOME MEASURES The Practice Environment Scale of the Nursing Work Index was used to measure the work environment. The perception of quality and safety of care was evaluated via a Likert-type scale. The risk of burnout was assessed using the Maslach Burnout Inventory scale. RESULTS A total of 2,183 nurse responses were included (response rate of 47.8%). Seventy-six percent of nurses reported at least one unfinished nursing care activity during their last shift. The staffing and resource adequacy subdimension of the Practice Environment Scale of the Nursing Work Index had the strongest correlation with unfinished nursing care. An increase in unfinished nursing care led to significantly lower perceived quality and safety of care and an increase in high risk of burnout. Unfinished nursing care appears to be a mediating factor for the association between staffing and resource adequacy and the quality and safety of care perceived by nurses and risk of burnout. CONCLUSIONS Unfinished nursing care, which is highly related to staffing and resource adequacy, is associated with increased odds of nurses being at risk of burnout and reporting a lower level of perceived quality of care. IMPLICATIONS FOR CLINICAL PRACTICE The monitoring of unfinished nursing care in the intensive care unit is an important early indicator of problems related to adequate staffing levels, the well-being of nurses, and the perceived quality of care.

Abstract
OBJECTIVES To explore communication strategies intensive care clinicians and patients' family members prefer for expressing empathy during family-clinician conversations. RESEARCH METHODOLOGY/DESIGN Mixed-methods survey study. SETTING Two medical ICUs of a German academic tertiary care hospital. MAIN OUTCOME MEASURES Using a self-developed online survey with closed and open-ended questions with free-text options, the participants' preferences of communication strategies for expressing empathy were investigated. Quantifiable similarities and differences were determined by statistical analysis. Qualitative themes were derived at by directed content analysis. FINDINGS The responses of 94 family members, 42 nurses, and 28 physicians were analysed (response rate: 45.3 %). Four communication strategies were deduced: (1) reassuring the families that the intensive care unit team will not abandon neither them nor the patient, (2) acknowledging emotions and offering support, (3) saying that the families are welcome and cared for in the intensive care unit, (4) providing understandable information. In comparison, the families considered an expression of nonabandonment as more empathic than the physicians did (p =.031,r = 0.240), and those expressions focussing solely on the family members' well-being (p =.012,r = 0.228) or comprising evaluative wording ("good", "normal") (p =.017,r = 0.242) as less empathic than the nurses did. Unanimously advocated nonverbal communication strategies included to listen attentively and to avoid interrupting as well as being approachable and honest. CONCLUSION The participants' preferences supported expert recommendations and highlighted that it is not only important what the clinicians say but also how they say it. Further research is needed to elucidate ways of successfully expressing empathy during family-clinician conversations in the intensive care unit. IMPLICATIONS FOR CLINICAL PRACTICE Intensive care unit clinicians are encouraged to practice active listening and to express their caring and nonabandonment. It is further suggested to reflect on and adjust pertinent nonverbal behaviours and relational aspects of their communication, as applicable.

Abstract
INTRODUCTION The frailty present at hospital admission and the stressors to which patients are subjected during their stay may increase dependency at hospital discharge. OBJECTIVES To assess the predictive validity of the Clinical Frailty Scale-España (CFS-Es) on increased dependency at 3 and 12 months (m) after hospital discharge. METHODOLOGY Multicentre cohort study in 2020-2022. Including patients with >48 h stay in intensive care units (ICU) and non-COVID-19. VARIABLES pre-admission frailty (CFS-Es). Sex, age, days of stay (ICU and hospital), dependency on admission and at 3 m and 12 m after discharge (Barthel index), muscle weakness (Medical Research Council Scale sum score <48), hospital readmissions. STATISTICS descriptive and multivariate analysis. RESULTS 254 cases were included. Thirty-nine per cent were women and the median [Q1-Q3] age was 67 [56-77] years. SAPS 3 on admission (median [Q1-Q3]): 62 [51-71] points. Frail patients on admission (CFS-Es 5-9): 58 (23%). Dependency on admission (n = 254) vs. 3 m after hospital discharge (n = 171) vs. 12 m after hospital discharge (n = 118): 1) Barthel 90-100: 82% vs. 68% vs. 65%. 2) Barthel 60-85: 15% vs. 15% vs. 20%. 3) Barthel 0-55: 3% vs. 17% vs. 15%. In the multivariate analysis, adjusted for the variables recorded, we observed that frail patients on admission (CFS-Es 5-9) are 2.8 times (95%CI: 1.03-7.58; p = 0.043) more likely to increase dependency (Barthel 90-100 to <90 or Barthel 85-60 to <60) at 3 m post-discharge (with respect to admission) and 3.5 times (95%CI: 1.18-10.30; p = 0.024) more likely to increase dependency at 12 m post-discharge. Furthermore, for each additional CFS-Es point there is a 1.6-fold (95%CI: 1.01-2.23; p = 0.016) greater chance of increased dependency in the 12 m following discharge. CONCLUSIONS CFS-Es at admission can predict increased dependency at 3 m and 12 m after hospital discharge.

Abstract
INTRODUCTION This study compared the performance of the artificial neural network (ANN) model with the Acute Physiologic and Chronic Health Evaluation (APACHE) II and IV models for predicting hospital mortality among critically ill patients in Hong Kong. METHODS This retrospective analysis included all patients admitted to the intensive care unit of Pamela Youde Nethersole Eastern Hospital from January 2010 to December 2019. The ANN model was constructed using parameters identical to the APACHE IV model. Discrimination performance was assessed using area under the receiver operating characteristic curve (AUROC); calibration performance was evaluated using the Brier score and Hosmer-Lemeshow statistic. RESULTS In total, 14 503 patients were included, with 10% in the validation set and 90% in the ANN model development set. The ANN model (AUROC=0.88, 95% confidence interval [CI]=0.86-0.90, Brier score=0.10; P in Hosmer-Lemeshow test=0.37) outperformed the APACHE II model (AUROC=0.85, 95% CI=0.80-0.85, Brier score=0.14; P<0.001 for both comparisons of AUROCs and Brier scores) but showed performance similar to the APACHE IV model (AUROC=0.87, 95% CI=0.85-0.89, Brier score=0.11; P=0.34 for comparison of AUROCs, and P=0.05 for comparison of Brier scores). The ANN model demonstrated better calibration than the APACHE II and APACHE IV models. CONCLUSION Our ANN model outperformed the APACHE II model but was similar to the APACHE IV model in terms of predicting hospital mortality in Hong Kong. Artificial neural networks are valuable tools that can enhance real-time prognostic prediction.

Zhang HL, Liu F, Lang HJ. The relationship between role ambiguity and anxiety in intensive care unit nurses: The mediating role of emotional intelligence. Intensive Crit Care Nurs 2024; 81:103597. [PMID: 38029677 DOI: 10.1016/j.iccn.2023.103597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 11/11/2023] [Accepted: 11/18/2023] [Indexed: 12/01/2023]
Abstract
BACKGROUND Role ambiguity is recognized as a significant psychological risk stressor in nursing practice, which undermines the psychological well-being of nurses. Since the well-being of nurses plays a crucial role in ensuring positive patient outcomes, it becomes imperative to identify strategies for improving nurses' psychological well-being. OBJECTIVES This study aimed to explore the effects of role ambiguity on anxiety in intensive care unit nurses and the mechanisms mediating emotional intelligence. METHODS In April-June 2023, a convenience sampling method was used to collect data from 360 intensive care unit nurses in a total of 7 hospitals in Shaanxi Province, Hunan Province, Beijing, and Jiangsu Province, China. A linear regression model was used to verify the mediating effect. RESULTS Role ambiguity was significantly and positively associated with anxiety in ICU nurses (p < 0.01). A mediating mechanism between role ambiguity and anxiety was established for emotional intelligence (p < 0.01). CONCLUSIONS Role ambiguity has a significant impact on the mental health of intensive care nurses, and emotional intelligence plays a mediating role in reducing role ambiguity and anxiety in nurses. IMPLICATIONS FOR CLINICAL PRACTICE This study highlights that role ambiguity in the intensive care unit setting increases nurses' anxiety, while emotional intelligence alleviates the anxiety associated with role ambiguity. Creating support systems and improving the environment is a top priority for nursing administrators. This includes, but is not limited to, clarifying the roles of nurses, conducting social-emotional training, and developing emotional intelligence to prevent and regulate nurses' anxiety and maintain mental health.

Abstract
PURPOSE We aimed to study the prevalence of frailty, evaluate risk factors, and understand impact on outcomes in India. METHODS This was a prospective registry-embedded cohort study across 7 intensive care units (ICUs) and included adult patients anticipated to stay for at least 48 h. Primary exposure was frailty, as defined by a score ≥ 5 on the Clinical Frailty Scale and primary outcome was ICU mortality. Secondary outcomes included in-hospital mortality and resource utilization. We used generalized linear models to evaluate risk factors and model association between frailty and outcomes. RESULTS 838 patients were included, with median (IQR) age 57 (42,68) yrs.; 64.8% were male. Prevalence of frailty was 19.8%. Charlson comorbidity index (OR:1.73 (95%CI:1.39,2.15)), Subjective Global Assessment categories mild/moderate malnourishment (OR:1.90 (95%CI:1.29, 2.80)) and severe malnourishment (OR:4.76 (95% CI:2.10,10.77)) were associated with frailty. Frailty was associated with higher odds of ICU mortality (adjusted OR:2.04 (95% CI:1.25,3.33)), hospital mortality (adjusted OR:2.36 (95%CI:1.45,3.84)), development of stage2/3 AKI (unadjusted OR:2.35 (95%CI:1.60, 3.43)), receipt of non-invasive ventilation (unadjusted OR:2.68 (95%CI:1.77, 4.03)), receipt of vasopressors (unadjusted OR:1.47 (95%CI:1.04, 2.07)), and receipt of kidney replacement therapy (unadjusted OR:3.15 (95%CI:1.90, 5.17)). CONCLUSIONS Frailty is common among critically ill patients in India and is associated with worse outcomes. STUDY REGISTRATION CTRI/2021/02/031503.

Abstract
BACKGROUND The main objective was to test whether the Renal Angina Index (RAI), calculated on patient admission to the pediatric intensive care unit (PICU), is associated with the risk of acute kidney injury (AKI) based on the Kidney Disease: Improving Global Outcomes (KDIGO) (stage ≥ 2) in 72 h. The specific aim was to analyze the performance of the RAI at a specialized oncology PICU. METHODS Retrospective cohort study involving two pediatric intensive care units located within a general hospital and an oncology hospital. Children aged ≥ 3 months to < 18 years admitted to the intensive care units in 2017 with a length of stay ≥ 72 h were included. RESULTS The sample included 249 patients, of which 51% were male (127 patients), with median age of 77 months, and mean ICU stay of 5 days. Of the total admissions, 141 were clinical (57%) and 108 surgical. The rate of AKI was 15% and death rate within 30 days was 13%. Having a positive RAI on admission showed a statistically significant association with AKI at Day 3 (OR = 18.5, 95%CI = 4.3 - 78.9, p < 0.001) and with death (OR = 3.9, 95%CI = 1.6 - 9.9, p = 0.004). The accuracy of the RAI in the cancer population was 0.81 on the ROC curve (95%CI 0.74, 0.88). CONCLUSIONS The RAI is a useful tool for predicting AKI and death in critically ill children, including in oncology units.

Abstract
OBJECTIVE To establish a new machine learning-based method to adjust positive end-expiratory pressure (PEEP) using only already routinely measured data. DESIGN Retrospective observational study. SETTING Intensive care unit (ICU). PATIENTS OR PARTICIPANTS 51811 mechanically ventilated patients in multiple ICUs in the USA (data from MIMIC-III and eICU databases). INTERVENTIONS No interventions. MAIN VARIABLES OF INTEREST Success parameters of ventilation (arterial partial pressures of oxygen and carbon dioxide and respiratory system compliance) RESULTS: The multi-tasking neural network model performed significantly best for all target tasks in the primary test set. The model predicts arterial partial pressures of oxygen and carbon dioxide and respiratory system compliance about 45 min into the future with mean absolute percentage errors of about 21.7%, 10.0% and 15.8%, respectively. The proposed use of the model was demonstrated in case scenarios, where we simulated possible effects of PEEP adjustments for individual cases. CONCLUSIONS Our study implies that machine learning approach to PEEP titration is a promising new method which comes with no extra cost once the infrastructure is in place. Availability of databases with most recent ICU patient data is crucial for the refinement of prediction performance.

Abstract
OBJECTIVES To identify risk factors for surgical site infections following cardiosurgery in an area endemic for multidrug resistant organisms. DESIGN Single-center, historical cohort study including patients who underwent cardiosurgery during a 6-year period (2014-2020). SETTING Joint Commission International accredited, multiorgan transplant center in Palermo, Italy. MAIN OUTCOME MEASURES Surgical site infection was the main outcome. RESULTS On a total of 3609 cardiosurgery patients, 184 developed surgical site infection (5.1 %). Intestinal colonization with multidrug resistant organisms was more frequent in patients with surgical site infections (69.6 % vs. 33.3 %; p < 0.001). About half of surgical site infections were caused by Gram-negative bacteria (n = 97; 52.7 %). Fifty surgical site infections were caused by multidrug resistant organisms (27.1 %), with extended-spectrum Beta-lactamase-producing Enterobacterales (n = 16; 8.7 %) and carbapenem-resistant Enterobacterales (n = 26; 14.1 %) being the predominant resistance problem. However, in only 24 of surgical site infections caused by multidrug resistant organisms (48 %), mostly carbapenem-resistant Enterobacterales (n = 22), a pathogen match between the rectal surveillance culture and surgical site infections clinical culture was demonstrated. Nevertheless, multivariate logistic regression analysis identified a rectal swab culture positive for multidrug resistant organisms as an independent risk factor for SSI (odds ratio 3.95, 95 % confidence interval 2.79-5.60). Other independent risk factors were female sex, chronic dialysis, diabetes mellitus, previous cardiosurgery, previous myocardial infarction, being overweight/obese, and longer intubation time. CONCLUSION In an area endemic for carbapenem-resistant Enterobacterales, intestinal colonization with multidrug resistant organisms was recognized as independent risk factor for surgical site infections. IMPLICATIONS FOR CLINICAL PRACTICE No causal relationship between colonization with resistant pathogens and subsequent infection could be demonstrated. However, from a broader epidemiological perspective, having a positive multidrug resistant organisms colonization status appeared a risk factor for surgical site infections. Therefore, strict infection control measures to prevent cross-transmission remain pivotal (e.g., nasal decolonization, hand hygiene, and skin antisepsis).

Abstract
BACKGROUND Clinical studies have not fully assessed the potential impact of patients' biochemical indicators on the rate of positive for central venous catheter-tip microorganism culture (PCMC). METHODS Data were obtained from an online Medical Information Mart for Intensive Care IV database. Patients who were ≥18 years old and had central venous catheter-tip culture results without continuous renal replacement therapy were included in the study. A comparison of patient characteristics and their biochemical indicators was made between negative and positive culture results. RESULTS A total of 5,323 patients were included in the analysis, including 612 positive (PCMC group) and 4,711 negative culture results (negative for central venous catheter tip catheter-tip microorganism culture [NCMC] group). The only influence factor on PCMC in this study was the serum creatinine (Scr) (odds ratio: 1.312, 95% confidence interval: 1.084-1.590, P = .005), according to a binary logistic regression analysis. The cut-off value of Scr was 3.25 mg/dL. The prevalence of PCMC (27.1% vs 9.1%, P < .001) and Staphylococcus aureus (43.0% vs 18.6%, P < .001) for central venous catheter-tip culture results was much higher in patients with Scr ≥ 3.25 mg/dL than those Scr < 3.25 mg/dL. CONCLUSIONS We used the large dataset collected from Medical Information Mart for Intensive Care IV to show that patients with Scr ≥ 3.25 mg/dL had an increased risk for PCMC.
