Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU

Chinese Version of the Nonverbal Pain Assessment Tool: Critical Patient Reliability and Validity

AIMS AND OBJECTIVES

To translate and validate the Nonverbal Pain Assessment Tool.

BACKGROUND

Timely assessment of the pain degree of nonverbal intensive care unit (ICU) patients can provide humanistic care. However, there is a lack of pain assessment tools that can meet the needs of patients who cannot use language in ICUs in China.

DESIGN

A cross-sectional survey.

METHODS

We conducted forward-backward translation of the Nonverbal Pain Assessment Tool. A total of 300 critically ill patients in the intensive care unit who could not communicate verbally completed the Chinese version of the Nonverbal Pain Assessment Tool and the Critical Care Pain Observation Tool. Exploratory and confirmatory factor analyses were performed to verify structural validity, and content validity and reliability analyses were also conducted.

RESULTS

The Nonverbal Pain Assessment Tool demonstrated high internal consistency (α = 0.901) and interrater reliability (intraclass correlation coefficient = 0.981), with good split-half reliability. Content validity was established through acceptable item-level content validity index and scale-level content validity index scores. Exploratory factor analysis showed a single factor explaining 71.79% of total variance, and confirmatory factor analysis confirmed good model fit. The Spearman rank correlation coefficient was 0.917 between the Nonverbal Pain Assessment Tool and the Critical Care Pain Observation Tool. The Chinese Nonverbal Pain Assessment Tool demonstrated significant differences in scores between different states of consciousness and illness severity, supporting its known-groups validity.

CONCLUSION

The Chinese version of the Nonverbal Pain Assessment Tool is a reliable and valid tool for nonverbal pain assessment in ICU patients in China.

RELEVANCE TO CLINICAL PRACTICE

The Chinese version of the Nonverbal Pain Assessment Tool can assess the pain of patients who cannot use language in ICU, which provides a new valuable assessment tool for Chinese clinicians and nurses in pain assessment and management.

Early mobilization in patients with aneurysmal subarachnoid haemorrhage may im-prove functional status and reduce cerebral vasospasm rate: a systematic review with meta-analysis

OBJECTIVE

The primary aim of this study was to evaluate the safety and efficacy of early mobilization in patients with aneurysmal subarachnoid haemorrhage.

DESIGN

Systematic review with meta-analysis of randomized controlled studies and observational studies.

PATIENTS

Patients with aneurysmal subarachnoid haemorrhage.

METHODS

PubMed, Embase, CINAHL, Web of Science, Pedro, and the Cochrane Library databases were searched. A systematic review and meta-analysis were performed. Screening and data extraction were performed by 2 independent reviewers.

RESULTS

Sixteen studies involving 1,757 patients were included. Meta-analysis of the data estimated that early mobilization improved mRS score at discharge (mean difference -1.39, 95% CI -2.51 to -0.28, I2 = 86%) and at 3 months (mean difference -1.10, 95% CI -1.54 to -0.66, I2 = 7%). Early mobilization was associated with a reduction in cerebral vasospasm rate, both radiological (OR 0.66, 95% CI 0.45 to 0.96, I2 = 7%) and clinical (OR 0.44, 95% CI 0.27 to 0.72, I2 = 8%); 6% of mobilization sessions involved adverse events, mostly haemodynamic changes.

CONCLUSION

This review found moderate-quality evidence supporting the safety and effectiveness of early mobilization in patients with SAH. Further randomized controlled trials are needed to identify the appropriate mobilization strategy and confirm these results.

Olanzapine Versus Quetiapine: Corrected QT Changes in Critically Ill Patients

BACKGROUND

Olanzapine and quetiapine are frequently administered atypical antipsychotic medications and their effects on the corrected QT (QTc) in the critically ill population remain understudied.

OBJECTIVE

The objective of this study was to compare the impact of olanzapine and quetiapine on QTc changes in critically ill patients.

METHODS

This was a single-center, retrospective analysis. Adult patients admitted to the intensive care unit (ICU) from January 2023 through July 2023 were included if they received ≥2 doses of either olanzapine or quetiapine within a 48-hour period and had one QTc evaluated within 48 hours of antipsychotic initiation. The major endpoint was a composite of the incidence of QTc prolongation (defined as QTc > 500 ms or QTc > 60 ms above baseline) following antipsychotic initiation. Univariable and multivariable analyses were performed to identify risk factors for QTc prolongation.

RESULTS

There was no statistical difference in the major composite endpoint between patients in the olanzapine and quetiapine groups (8/83 [9.6%] vs 19/129 [14.7%]; P = .28). The incidence of QTc > 500 ms (7/244 [2.9%] vs 20/427 [4.7%]; P = .25) and change from baseline >60 ms (5/244 [2.0%] vs 17/427 [4.0%]; P = .26) were not statistically different between the olanzapine and quetiapine groups, respectively. There were no occurrences of Torsades de Pointes or extrapyramidal symptoms in either group.

CONCLUSION AND RELEVANCE

The results of this study suggest olanzapine and quetiapine may have similar impact on QTc prolongation in critically ill patients. These findings could contribute to safer prescribing practices in the ICU.

Impact of an enhanced recovery after surgery program integrating cardiopulmonary rehabilitation on post-operative prognosis of patients treated with CABG: protocol of the ERAS-CaRe randomized controlled trial

BACKGROUND

Coronary artery bypass grafting is associated with a high occurrence of postoperative cardiopulmonary complications. Preliminary evidence suggested that enhanced recovery after surgery can effectively reduce the occurrence of postoperative cardiopulmonary complications. However, enhanced recovery after surgery with systematic integration of cardiopulmonary rehabilitation (ERAS-CaRe) into for Coronary artery bypass grafting has not been evaluated so far. We thus design the ERAS-CaRe randomized-controlled trial to evaluate possible superiority of embedding cardiopulmonary rehabilitation in ERAS over ERAS alone as well as to investigate effects of differential timing of cardiopulmonary rehabilitation within enhanced recovery after surgery (pre-, post-, perio-operative) on post-operative cardiopulmonary complications following Coronary artery bypass grafting surgery.

METHODS

ERAS-CaRe is a pragmatic, randomized-controlled, parallel four-arm, clinical trial. Three hundred sixty patients scheduled for Coronary artery bypass grafting in two Chinese hospitals will be grouped randomly into (i) Standard enhanced recovery after surgery or (ii) pre-operative ERAS-CaRe or (iii) post-operative ERAS-CaRe or (iv) perio-operative ERAS-CaRe. Primary outcome is the occurrence of cardiopulmonary complications at 10 days after Coronary artery bypass grafting. Secondary outcomes include the occurrence of other individual complications including cardiac, pulmonary, stroke, acute kidney injury, gastrointestinal event, ICU delirium rate, reintubation rate, early drainage tube removal rate, unplanned revascularization rate, all-cause mortality, ICU readmission rate, plasma concentration of myocardial infarction-related key biomarkers etc. DISCUSSION: The trial is designed to evaluate the hypothesis that a cardiopulmonary rehabilitation based enhanced recovery after surgery program reduces the occurrence of cardiopulmonary complications following Coronary artery bypass grafting and to determine optimal timing of cardiopulmonary rehabilitation within enhanced recovery after surgery. The project will contribute to increasing the currently limited knowledge base in the field as well as devising clinical recommendations.

TRIAL REGISTRATION

The trial was registered at the Chinese Clinical Trials Registry on 25 August 2023 (ChiCTR2300075125; date recorded: 25/8/2023, https://www.chictr.org.cn/ ).

Adherence to optimal delirium management practices in intensive care units in Brazil: a nationwide survey

BACKGROUND

Effective delirium management is crucial, considering its association with adverse outcomes. Adherence to best practices has the potential to reduce the incidence and prevalence of delirium and improve health outcomes.

OBJECTIVES

The objectives of this project were to describe self-assessed adherence to best practices in delirium management by health care professionals in intensive care units (ICUs) in Brazil, assess the health care professionals' perception of the importance of adequate delirium prevention and treatment in ICUs, and compare the compliance rates with best practices between public and private ICUs.

METHOD

A cross-sectional study was conducted in Brazil using an online questionnaire consisting of three parts, namely, data about the health care professionals and the ICU in which they worked; statements about the 17 best practices; and questions related to perceptions of delirium prevention and management by ICU physicians and nurses. The survey was sent to email addresses registered with the Brazilian Association of Intensive Care Medicine.

RESULTS

The compliance rate exceeded 50% for only eight best practices. These included the identification and management of pressure sores and falls in delirium patients, with compliance rates of 77.8% and 74.1%, respectively.

CONCLUSION

Among ICU professionals in Brazil, adherence to best practices in delirium management is low, particularly for practices involving patient education and involvement of their relatives in their care. These results emphasize the importance of enhancing delirium management in Brazilian health care institutions, regardless of hospital classification.

Registered nurses' experiences of caring for patients with hypoactive delirium after cardiac surgery - A qualitative study

OBJECTIVES

Delirium is a common post-cardiac surgery complication that presents as acute changes in mental abilities with confused thinking and a lack of awareness of the surroundings. Delirium symptoms present in hyperactive- and hypoactive forms. Hypoactive delirium is often overlooked. Although nursing interventions are important in preventing and treating hypoactive delirium, studies focusing on nurses' experiences of hypoactive delirium are scarce. This study describes registered nurses' experiences of caring for patients with hypoactive delirium after cardiac surgery.

RESEARCH METHODOLOGY/DESIGN

This was a qualitative descriptive study with an inductive approach. Data was collected through focus group interviews with 12 registered nurses with experience in caring for cardiac surgery patients with hypoactive delirium. The study complied with the Consolidated Criteria for Reporting Qualitative Research.

SETTING

A cardiac surgery department at a Swedish University Hospital.

FINDINGS

The analysis resulted in one main category; "Navigating the complexities of care when caring for patients with hypoactive delirium" and three sub-categories: "Challenges, "Nursing interventions" and "Promoting a team approach".

CONCLUSION

Delirium assessment and nursing interventions are perceived as essential yet demanding. when caring for patients with hypoactive delirium. Nursing interventions like maintaining the circadian rhythm and offering emotional support need to be prioritised by the nurses, in line with the autonomy of the registered nurse's profession. Moreover, the team around the patient is crucial for detecting and treating hypoactive delirium, and it is important to involve other professionals as well as the patient's relatives. Future research is needed to develop assessment instruments that more accurately capture hypoactive delirium in the postoperative setting.

IMPLICATIONS FOR CLINICAL PRACTICE

Despite the use of screening tools, nurses still experience challenges in detecting the symptoms of hypoactive delirium, indicating a need for more clinically effective screening tools for hypoactive delirium. Nursing interventions are emphasised in the care of patients with hypoactive delirium.

The comfort perception in the critically ill patient from the Kolcaba theoretical model

BACKGROUND

The stay in a critical care unit (CCU) has a serious impact on physical condition causing numerous discomfort factors such as pain or difficulty in communicating. All of these are associated with possible sequelae following discharge from the Intensive Care Unit (ICU) named post-ICU syndrome. The Kolcaba Comfort Theory allows, from a holistic approach, to identify care needs from the patient's perspective using instruments such as the General Comfort Questionnaire (GCQ).

OBJECTIVES

To determine the comfort level of patients admitted to the CCU using the GCQ of Kolcaba and to identify the discomfort factors.

METHODS

Cross-sectional descriptive observational prospective study.

POPULATION

580 patients admitted to adult CCU of two high complexity hospitals from June 2015 to March 2020 with stay ≥24 h were interviewed. Descriptive analysis, Student's t-test and ANOVA and multivariate analysis were performed using SPSS v26 and STATA v16.

RESULTS

The mean age was 52,62 (16,21), 357 (61,6%) were male and 434 (74,8%) were believers. The type of admission was planned in 322 (55,5%) and the most prevalent reason for admission was surgical 486 (83,8%). The median pain score (NRS) was 3,00 [0-4] and severity score (APACHE II) was 13,26 (5,89), the median length of stay was 4,00 [2-7] days. The mean comfort level was 3,02 (0,31) showing the highest value Reanimation 3.02 (0.30) and the lowest Trauma and Emergency Unit 2.95 (0.38). Statistically significant differences were found between the units in the comfort level of patients >65 years of age (p = 0.029). The Relief comfort type obtained the lowest mean 2.81 (0.33) and the physical context 2.75 (0.41) in the three units. In the multivariate analysis, statistically significant differences were found between the comfort level and the pain level: no pain (p = 0,000) OR 4,361 CI [2,184-8,707], mild pain (p = 0,000) OR 4,007 CI [2,068-7,763], moderate pain (p = 0,007) OR 2,803 CI [1,328-5,913], and the APACHE II score equal to or greater than 10 (p = 0,000) OR 0,472 CI [0,316-0,705].

CONCLUSIONS

The comfort level showed high scores in all three units. The physical and environmental contexts and the relief comfort type negatively affected the perception of comfort. The variables that explained comfort were pain and severity of illness. The evaluation of comfort from the patient's perspective through the GCQ could be considered an indicator of quality of nursing interventions.

Effectiveness of the ABCDEF Bundle to Manage and Prevent Delirium: Pre- and Postintervention Quasi-Experimental Study

To investigate effectiveness of the ABCDEF bundle to manage and prevent delirium.

BACKGROUND

ICU delirium is a common hospital problem that 80% of critically ill patients in the ICU experience. The ABCDEF bundle is one of the tools that included in Delirium guidelines to manage critically ill patients.

RESEARCH DESIGN

Pre- and post intervention a quasi-experimental design was utilized in the present study.

SETTING

This study was conducted in the intensive care units of Assiut University Hospital.

METHODS

A total of 60 mechanically ventilated patients were recruited using inclusion and exclusion criteria. The ABCDEF bundle was implemented every day for the first 7 days of ICU admission, and patient sedation and delirium status were assessed using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Sedation instrument measures were utilized in data collection.

RESULTS

Significant differences were found in the incidence of delirium: 20% in the study group versus 70% in the control group. The increased mean of days without delirium ICU stay was 4.6333 in the study group and 1.1000 in the control group, with P value = .001.

CONCLUSION

The mechanically ventilated patients exposed to the implementation of the ABCDE bundle experienced fewer delirium signs than before the ABCDE bundle was implemented.

Characterizing usual-care physical rehabilitation in Canadian intensive care unit patients: a secondary analysis of the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength pilot randomized controlled trial

PURPOSE

Physical rehabilitation (PR) in the intensive care unit (ICU) may improve outcomes for survivors but clinical trial results have been discordant. We hypothesized that discordant results may reflect treatment heterogeneity received by "usual care" comparator groups in PR studies. Usual-care PR is typically underspecified, which is a barrier to comparing results across treatment studies. The primary objective of the present study was to describe the usual-care PR received by critically ill patients enrolled in the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength (CYCLE) pilot randomized controlled trial (RCT) of PR. Other objectives were to help contextualize current research and provide data for international comparison.

METHODS

In this secondary analysis of the CYCLE pilot RCT, patients were randomized to in-bed cycling and usual-care PR or usual-care PR alone. Physiotherapists documented usual-care PR including therapy received, type of activity, duration, adverse events and consequences, reasons for no PR, and concurrent relevant medical interventions. We characterized usual care using descriptive statistics at the cohort and patient levels.

RESULTS

Across seven Canadian centres, 30 patients were randomized to usual-care PR. The median [interquartile range (IQR)] ICU stay was 10 [9-24] days and patients received PR on a median [IQR] of 5 [3-9] days for 23 [17-30] min per day. Eighteen patients (60%) stood, marched, or walked during usual care. Transient adverse events occurred in three patients on 1.5% (3/198) of days and none prompted session termination.

CONCLUSIONS

In the usual-care arm of the CYCLE pilot RCT, PR was delivered on half of ICU days and over half of patients stood, marched, or walked. Adverse events during usual-care PR were uncommon.

Knowledge, attitudes, and perceived barriers regarding pain assessment and management among Thai critical care nurses: A cross-sectional study

BACKGROUND

Pain is a distressing problem which commonly occurs among critically ill patients. Nurses' knowledge of, attitudes, and perceived barriers to pain assessment and management can influence the effectiveness of nursing care.

OBJECTIVE

To explore the current knowledge of, attitudes, and perceived barriers to pain assessment and management among Thai critical care unit nurses.

METHODS

A cross-sectional survey conducted between November 2022 and January 2023 among 158 Thai nurses working in one of eight adult critical care units in a tertiary hospital, evaluated their knowledge of, attitudes, and perceived barriers to pain assessment and management.

RESULTS

Nurses possessed inadequate knowledge and negative attitudes regarding pain assessment and management. The most important barrier to pain assessment and management was "patients are unable to communicate their pain". The results showed a significantly weak positive correlation between nurses' attitudes toward pain assessment and management age (r = 0.26, p = 0.001), year of ICU experience (r = 0.29, p < 0.001), and obtaining a certificate in intensive care nursing (r = 0.37, P < 0.001).

CONCLUSIONS

Thai critical care unit nurses possessed inadequate knowledge and negative attitudes. Further training and education regarding pain assessment and management could include case studies or simulation and immersive virtual reality to improve critical care unit nurses' knowledge and attitudes as well as identifying potential barriers to pain assessment and management in the critical care settings.

IMPLICATIONS FOR CLINICAL PRACTICE

The implications for clinical practice recommend that continued quality assurance procedures should be implemented and maintained to evaluate the effectiveness of current pain assessment practices. Additionally, the perceived barriers to effective pain assessment and management should be considered and managed not only through continued education and training but could include using nursing case review, morbidity and mortality data identifying those patients that experience chronic pain post-ICU discharge.

Dexmedetomidine versus ketamine in improving tolerance to noninvasive ventilation after blunt chest trauma: A randomized, double-blinded, placebo-controlled trial

Background and Aims

Even though patient tolerance is critical to the success of noninvasive ventilation (NIV), research on using sedation to improve tolerance to NIV after traumatic chest injuries is limited. We hypothesized that dexmedetomidine would be superior to ketamine in terms of patient tolerance and lengthening the NIV sessions after blunt chest trauma.

Material and Methods

This randomized, double-blinded, placebo-controlled trial included 45 patients of both genders aged 18-60 who needed NIV after blunt chest trauma. The patients were randomly assigned to one of three groups (n = 15) for receiving dexmedetomidine, ketamine, or placebo (0.9% sodium chloride solution) infusion to maintain a Richmond Agitation Sedation Scale (RASS) score between 0 and - 3 during two successive NIV sessions. Patients were evaluated for the duration of the NIV sessions, RASS, Visual Analog Scale (VAS), and the total amount of rescue analgesia consumed.

Results

The mean duration of the NIV sessions was significantly longer in patients who received dexmedetomidine (P < 0.001) or ketamine (P < 0.001) compared to placebo. However, the NIV durations did not differ significantly between the dexmedetomidine and ketamine groups (P > 0.05). The dexmedetomidine group had a significantly lower RASS score compared to the ketamine (P < 0.001) and placebo (P < 0.001) groups, whereas the ketamine group had a significantly lower VAS compared to the dexmedetomidine (P = 0.005) and placebo (P = 0.022) groups and required significantly less total morphine (P = 0.001) compared to the other groups.

Conclusion

The duration of the NIV sessions for patients with blunt chest trauma did not differ significantly between the dexmedetomidine and ketamine groups.

Ketamine analgo-sedation for mechanically ventilated critically ill adults: A rapid practice guideline from the Saudi Critical Care Society and the Scandinavian Society of Anesthesiology and Intensive Care Medicine

BACKGROUND

This Rapid Practice Guideline (RPG) aimed to provide evidence-based recommendations for ketamine analgo-sedation (monotherapy and adjunct) versus non-ketamine sedatives or usual care in adult intensive care unit (ICU) patients on invasive mechanical ventilation (iMV) and to identify knowledge gaps for future research.

METHODS

The RPG panel comprised 23 multinational multidisciplinary panelists, including a patient representative. An up-to-date systematic review and meta-analysis constituted the evidence base. The Grading Recommendations, Assessment, Development, and Evaluation approach, and the evidence-to-decision framework were used to assess the certainty of evidence and to move from evidence to decision/recommendation. The panel provided input on the balance of the desirable and undesirable effects, certainty of evidence, patients' values and preferences, costs, resources, equity, feasibility, acceptability, and research priorities.

RESULTS

Data from 17 randomized clinical trials (n = 898) and nine observational studies (n = 1934) were included. There was considerable uncertainty about the desirable and undesirable effects of ketamine monotherapy for analgo-sedation. The evidence was very low certainty and downgraded for risk of bias, indirectness, and inconsistency. Uncertainty or variability in values and preferences were identified. Costs, resources, equity, and acceptability were considered varied. Adjunctive ketamine therapy had no effect on mortality (within 28 days) (relative risk [RR] 0.99; 95% confidence interval [CI] 0.76 to 1.27; low certainty), and may slightly reduce iMV duration (days) (mean difference [MD] -0.05 days; 95% CI -0.07 to -0.03; low certainty), and uncertain effect on the cumulative dose of opioids (mcg/kg/h morphine equivalent) (MD -11.6; 95% CI -20.4 to -2.7; very low certainty). Uncertain desirable effects (cumulative dose of sedatives and vasopressors) and undesirable effects (adverse event rate, delirium, arrhythmia, hepatotoxicity, hypersalivation, use of physical restraints) were also identified. A possibility of important uncertainty or variability in patient-important outcomes led to a balanced effect that favored neither the intervention nor the comparison. Cost, resources, and equity were considered varied.

CONCLUSION

The RPG panel provided two conditional recommendations and suggested (1) against using ketamine as monotherapy analgo-sedation in critically ill adults on iMV when other analgo-sedatives are available; and (2) using ketamine as an adjunct to non-ketamine usual care sedatives (e.g., opioids, propofol, dexmedetomidine) or continuing with non-ketamine usual care sedatives alone. Large-scale trials should provide additional evidence.

Comparing Bispectral Index Monitoring vs Clinical Assessment for Deep Sedation in the ICU: Effects on Delirium Reduction and Sedative Drug Doses-A Randomized Trial

BACKGROUND

Sedative overdoses pose a risk of delirium among patients in the ICU, with potential mitigation through the use of a processed EEG monitor (the bispectral index [BIS]) to guide depth of sedation.

RESEARCH QUESTION

Can BIS-guided deep sedation (Richmond Agitation Sedation Scale [RASS] score, -4 or -5) reduce sedative dosage and increase delirium-free and coma-free (DFCF) days?

STUDY DESIGN AND METHODS

A randomized controlled trial was conducted in a tertiary mixed ICU, enrolling patients requiring deep sedation for > 8 h. Patients were assigned randomly to either the clinical assessment (CA) or BIS groups (BIS range, 40-60). Both groups used a BIS sensor, whereas the CA group's screen remained covered. After deep sedation, BIS sensors were removed, and delirium was assessed twice daily by researchers masked to the randomization. The primary outcome was the number of DFCF days within 14 days after deep sedation. Additionally, we compared doses of sedative drugs and BIS values during deep sedation.

RESULTS

Ninety-nine patients were included in the study. We found no significant difference in DFCF days (P = .1) between CA and BIS arms, but propofol doses were significantly lower in the BIS group (CA group, 1.77 mg/kg/h [95% CI, 1.60-1.93] vs BIS group, 1.44 mg/kg/h [95% CI, 1.04-1.83]; P = .03). During deep sedation, the CA group spent 46% of the total hours (95% CI, 35%-57%) with BIS values of < 40, whereas the BIS group spent 32% (95% CI, 25%-40%; P = .03). Subgroup analysis focusing on patients sedated for > 24 h revealed an increase in DFCF days in the BIS group (CA group: median, 1 day [interquartile range, 0-9 days] vs BIS group: median, 8 days [interquartile range, 0-13 days]; P = .04).

INTERPRETATION

In this study, BIS-guided deep sedation did not improve DFCF days, but did reduce sedative drug use. In patients requiring sedation for > 24 h, it showed an improvement in DFCF days.

Evaluation of the Impact of the Addition of Atypical Antipsychotics to Continuous Infusion Propofol Therapy

Purpose: The administration of sedatives to critically ill patients is a common practice in intensive care units (ICU) and has been associated with negative outcomes. To mitigate this, atypical antipsychotics are utilized as adjunctive therapy. This study aims to review and quantify overall effectiveness of the atypical antipsychotics quetiapine, risperidone, and olanzapine on reduction in the amount of continuous infusion propofol utilized in the ICU. Methods: This was an observational study that took place from February 27, 2021 to December 31, 2022. The primary outcome of this study was the percentage change in average propofol infusion rate (mcg/kg/min) from baseline to the greater than 24 to 48 hours period after atypical antipsychotic initiation. Secondary outcomes included ICU length of stay, duration of mechanical ventilation, QTc interval monitoring, and continuation of the antipsychotic without a valid indication. Descriptive statistics were utilized for the statistical analysis. Results: A total of 47 patients were included in the study. The average baseline propofol rate was 31 mcg/kg/min, which reduced 8.6% to 28.35 mcg/kg/min over the 0 to 24 hours period, was reduced by 19.4% compared to baseline to a rate of 25 mcg/kg/min during the greater than 24 to 48 hours period, and finally a percent reduction of 54.2% seen during the greater than 48 to 72 hours period to a rate of 14 mcg/kg/min. Conclusions: Patients who received an adjunctive antipsychotic saw resulting propofol rate reductions of 8.6% at 24 hours, 19.4% at 48 hours, and 54.2% at 72 hours. However, research on this topic should not end here, as further investigation with higher-level study design is needed to determine the true impact of these agents for this indication.

Pain management of adult sedated and ventilated patients in the intensive care units: A survey with free text responses

BACKGROUND

Pain management of sedated and ventilated patients in intensive care units lacks consistency.

OBJECTIVES

To investigate nurses' training, governance, practices, knowledge and attitudes relating to pain management in consideration of published guidelines and explore nurses' perspectives.

METHODS

A survey design, using an online questionnaire with free text responses, was employed. Quantitative and qualitative data from nurses working across different hospitals were collated and saved on Qualtrics platform. Quantitative data were analysed non-parametrically and narrative responses thematically. CROSS and SRQR reporting guidelines were adhered to.

OUTCOME MEASURES

Demographics, training, governance, clinical practice, knowledge, and attitudes.

RESULTS/FINDINGS

108 nurses participated with ninety-two completed surveys analysed. Analgesia was used to complete nursing tasks regardless of comfort needs (n = 49, 53.3 %). Changes in vital signs prompted opioid administration (n = 48, 52.1 %). Choice of analgesia depended on doctor's preference (n = 63, 68.5 %). Non-opioid therapy was administered before opioids (n = 42, 45.7 %). Sedatives were used to alleviate agitation(n = 50,54.3 %). No statistically significant difference in nurses' knowledge existed between hospitals. Weak positive relationship: r = [0.081], p = [0.441] between "knowledge scores" and "years of ICU experience" and weak negative relationship r = [-0.119], p = [0.260] between "knowledge scores" and "hours of clinical practice" was detected. Lack of training, resources, policies, high patient acuity and casual employment were acknowledged barriers to pain management. Two overarching themes emerged from narrative responses: "Pain assessment, where is it?" And "Priorities of critical illness."

CONCLUSION

The study uncovered pain management situation and examined nurses' demographics, training, governance, practices, knowledge and attitudes. Narrative responses highlighted barriers to pain management.

IMPLICATIONS FOR CLINICAL PRACTICE

Health organisations should provide education, institute governance and develop policies to inform pain management. Nurses' role encompasses updating knowledge, adhering to interventions and overcoming biases. This subsequently manifests as improvement in patient outcomes.

Exploring the Association Between Intravenous Lorazepam and Mortality Among Older Hospitalized Patients With and Without Cognitive Impairment

Background In a previously published study about the effects of an inpatient geriatrics program on mortality among older patients with and without cognitive impairment, intravenous (IV) lorazepam was unexpectedly found to be one of the variables associated with mortality in the multivariate analysis. The purpose of this study was to further explore the association between IV lorazepam and mortality. Materials and Methods This was a secondary data analysis of a previously published retrospective study. The setting was a 500-bed community-based hospital, Level-1 Trauma Center, and Stroke Center (Dallas, Texas, United States). Participants were all patients aged 70+ admitted between January 1, 2017, and December 31, 2019. Logistic regression was used to evaluate the association between IV lorazepam (defined as receiving ≥1 dose) and mortality (death during hospitalization) among patients with cognitive impairment [defined as in the original study using a list of >30 IInternational Classification of Diseases, Tenth Edition (ICD-10)] and without cognitive impairment. Covariables included age, gender, case mix index, ICU stay, sepsis, palliative care, oral benzodiazepines, oral and IV antipsychotics, and oral and IV opioids. Logistic regression was used to calculate the adjusted odds ratio (aORs) and 95% confidence intervals (CI) of mortality. Results Of 20,541 patients, 6,197 (30.2%) had cognitive impairment of which 1430 (23.1%) received IV lorazepam, with a mortality rate of 16.9%. Of 14,344 patients without cognitive impairment, 1,468 (10.2%) received IV lorazepam, with a mortality rate of 32.0%. After controlling for covariables, aORs for mortality among those who received IV lorazepam was 3.37 (95% CI: 2.52-4.50) for patients with cognitive impairment and 7.72 (95% confidence interval (CI): 6.09-9.79) without cognitive impairment. Even when ICU and palliative care patients were excluded, aOR for mortality remained high for those with (4.09; 95% CI: 2.17-7.69) and without cognitive impairment, 18.82 (95% CI: 13.39-26.46). Conclusion Despite the limitations of this exploratory study, including a lack of data on the dosage and duration of IV lorazepam, further research is warranted to examine the possible association between IV lorazepam and increased mortality among older hospitalized patients, both with and without cognitive impairment.

Prospective multi-center evaluation of the incidence of unplanned extubation and its outcomes in French intensive care units. The Safe-ICU study

BACKGROUND

We aimed to determine the epidemiology and outcomes of unplanned extubation (UE), both accidental and self-extubation, in ICU.

METHODS

A multicentre prospective cohort study was conducted in 47 French ICUs. The number of mechanical ventilation (MV) days, and planned and unplanned extubation were recorded in each center over a minimum period of three consecutive months to evaluate UE incidence. Patient characteristics, UE environmental factors, and outcomes were compared based on the UE mechanism (accidental or self-extubation). Self-extubation outcomes were compared with planned extubation using a propensity-matched population. Finally, risk factors for extubation failure (re-intubation before day 7) were determined following self-extubation.

RESULTS

During the 12-month inclusion period, we found a pooled UE incidence of 1.0 per 100 MV days. UE accounted for 9% of all endotracheal removals. Of the 605 UE, 88% were self-extubation and 12% were accidental-extubations. The latter had a worse prognosis than self-extubation (34% vs. 8% ICU-mortality, p < 0.001). Self-extubation did not increase mortality compared with planned extubation (8% vs. 11%, p = 0.075). Regardless of the type of extubation, planned or unplanned, extubation failure was independently associated with a poor outcome. Cancer, higher respiratory rate, lower PaO2/FiO2 at the time of extubation, weaning process not-ongoing, and immediate post-extubation respiratory failure were independent predictors of failed self-extubation.

CONCLUSION

Unplanned extubation, mostly represented by self-extubation, is common in ICU and accounts for 9% of all endotracheal extubations. While accidental extubations are a serious and infrequent adverse event, self-extubation does not increase mortality compared to planned extubation.

Patients' lived body experiences in the intensive care unit and beyond - a meta-ethnographic synthesis

INTRODUCTION

Physical therapists supporting patients in intensive care unit (ICU) rehabilitation can improve their clinical practice with insight in patients' lived body experiences.

OBJECTIVE

To gain insight in patients' lived body experiences during ICU stay and in recovery from critical illness.

METHODS

Through a comprehensive systematic literature search, 45 empirical phenomenological studies were identified. Patients' lived body experiences were extracted from these studies and synthesized following the seven-phase interpretative approach as described by Noblit and Hare.

RESULTS

Three lines of argument were illuminated: 1) "recovery from critical illness starts from a situation in which patients experience the lived body as unable;" 2) "patients experience progress in recovery from critical illness when the lived body is empowered;" and 3) "recovery from critical illness results in a lived body changed for life." Eleven third-order constructs were formulated as different kinds of bodies: 1) "an intolerable body;" 2) "an alienated body;" 3) "a powerless body;" 4) "a dependent body;" 5) "a restricted body;" 6) "a muted body;" 7) "a touched body;" 8) "a transforming body;" 9) "a re-discovering body;" 10) "an unhomelike body;" and 11) "a remembering body."

CONCLUSION

Patients' lived body experiences during ICU stay and in recovery from critical illness have richly been described in phenomenological studies and were synthesized in this meta-ethnography.

Implementation of a routine post-shift debriefing program in ICU aiming at quality-of-care improvement: A primary analysis of feasibility and impacts

OBJECTIVES

This report describes the implementation of a clinical debriefing (CD) program in intensive care units (ICU) and analyses its feasibility and its impact on staff well-being.

DESIGN

Observational study.

SETTING

From April to September 2023, post-shift CDs were run once a week in 2 out of 7 units in our department, using an adapted version of the DISCOVER-PHASE tool. CD sessions were performed face-to-face with volunteer members of the multidisciplinary ICU team.

MAIN OUTCOME MEASURES

After 6 months, a survey assessing the satisfaction of the debriefed teams was conducted. The impact of CD on staff well-being was assessed using three validated questionnaires (Maslach Burnout Inventory, Ways of Coping Checklist, Professional Quality of Life Scale) administered in the 7 units before and after the CD period.

RESULTS

A total of 44 CDs were performed, lasting 15 (4-35) min. There were 6 (1-9) attendees per CD, mainly nurses (64.6%). Discussions focused mainly on basic problems related to dysfunctional material, communication and organization inside the team. The two debriefed teams were satisfied of the program and gave 9, 8 and 8 out of 10 on a visual analogical scale for the climate of confidence of the DC, their organisation, and their ability to improve working conditions and quality of care, respectively. Subscores at the three questionnaires assessing staff well-being before and after the CD period were similar, whether teams experienced CD or not.

CONCLUSIONS

Implementing of post-shift debriefings in our ICU was feasible and well accepted. More prolonged programs are probably needed to demonstrate benefits on staff well-being.

IMPLICATIONS FOR CLINICAL PRACTICE

This report offers elements that other teams can use to successfully conduct post-shift debriefings and to plan future research on longer-term programs.

Usefulness of the 4A's test for detecting delirium in critically ill patients: a multicenter prospective observation study

The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is a robust and reliable instrument for discerning delirium within the specific context of the intensive care unit (ICU). Nonetheless, the CAM-ICU is burdened by various limitations, including a protracted learning curve and the need for frequent daily administration. The 4 A's Test (4AT) was formulated to assess delirium in hospitalized patients and may have distinct advantages over the CAM-ICU, particularly regarding practical applicability within the ICU bundle. This study was performed to assess the utility of the 4AT in detecting delirium in critically ill patients. This multicenter prospective observational study involved critically ill patients at four academic tertiary care hospitals in South Korea from June 2021 to September 2022. In total, 274 patients (median age, 64 years; 56.9% men) were included, and 75 (27.4%) developed delirium. The 4AT showed good performance in detecting ICU delirium (area under the curve, 0.879; P < 0.001). The 4AT showed a sensitivity of 74.0%, specificity of 95.4%, positive predictive value of 77.5%, negative predictive value of 94.6%, and accuracy of 91.7% for ICU detection of delirium. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the CAM-ICU for detecting ICU delirium were 71.3%, 97.1%, 83.8%, 94.1%, and 92.6%, respectively. The 4AT showed acceptable reliability and validity for detecting ICU delirium in critically ill patients. Because the 4AT is simpler and easier to learn, this scale could be a useful alternative to the CAM-ICU for detecting delirium in critically ill patients.

Management of analgosedation during noninvasive respiratory support: an expert Delphi consensus document developed by the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI)

BACKGROUND

Discomfort can be the cause of noninvasive respiratory support (NRS) failure in up to 50% of treated patients. Several studies have shown how analgosedation during NRS can reduce the rate of delirium, endotracheal intubation, and hospital length of stay in patients with acute respiratory failure. The purpose of this project was to explore consensus on which medications are currently available as analgosedatives during NRS, which types of patients may benefit from analgosedation while on NRS, and which clinical settings might be appropriate for the implementation of analgosedation during NRS.

METHODS

The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) selected a panel of experts and asked them to define key aspects of the use of analgesics and sedatives during NRS treatment. The methodology applied is in line with the principles of the modified Delphi and RAND-UCLA methods. The experts developed statements and supportive rationales which were then subjected to blind votes for consensus.

RESULTS

The use of an analgosedation strategy in adult patients with acute respiratory failure of different origins may be useful where there is a need to manage discomfort. This strategy should be considered after careful assessment of other potential factors associated with respiratory failure or inappropriate noninvasive respiratory support settings, which may, in turn, be responsible for NRS failure. Several drugs can be used, each of them specifically targeted to the main component of discomfort to treat. In addition, analgosedation during NRS treatment should always be combined with close cardiorespiratory monitoring in an appropriate clinical setting.

CONCLUSIONS

The use of analgosedation during NRS has been studied in several clinical trials. However, its successful application relies on a thorough understanding of the pharmacological aspects of the sedative drugs used, the clinical conditions for which NRS is applied, and a careful selection of the appropriate clinical setting.

Effect of prophylactic noninvasive oxygen therapy after planned extubation on extubation failure in high-risk patients: a retrospective propensity score-matched cohort study

Background

Extubation failure (EF) is common in the intensive care unit (ICU) and is associated with poor prognosis, especially in high-risk patients. However, the efficacy of prophylactic noninvasive oxygen therapy (NIT), including noninvasive ventilation (NIV) and high-flow nasal cannula (HFNC), in reducing EF in high-risk patients remains controversial. Therefore, we aimed to evaluate the effect of post-extubation prophylactic NIT on EF in high-risk patients.

Methods

This was a retrospective observational study conducted in the ICU from March 2018 to December 2023. We included adult patients at high risk for reintubation who were mechanically ventilated for over 24 h and successfully passed the spontaneous breathing trial (SBT). Immediately after extubation, patients underwent NIT or conventional oxygenation therapy (COT). The primary outcome was the EF rate within 7 days after extubation.

Results

There were 440 patients in the NIT group and 274 in the COT group. After propensity-score matching, 227 subjects were enrolled in each group. NIT reduced the rate of EF (18.0% vs. 34.3%, p < 0.001) and reintubation (10.5% vs. 18.2% p = 0.003) compared with COT, which was confirmed in propensity-matched cohort (17.6% vs. 32.2%, p < 0.001; 11.5% vs. 19.8%, p = 0.014). Multivariate logistic regression analysis indicated that prophylactic NIT (p = 0.001) and higher ROX index (p = 0.022) were associated with reduced risk of EF. While higher fluid balance (p = 0.013), higher RSBI (p < 0.001), and the occurrence of delirium (p = 0.032) may be the risk factors for EF. Subgroup analysis showed that post-extubation NIT was more effective in elderly patients, and HFNC was non-inferior to NIV in reducing EF. While HFNC had a tendency to reduce the incidence of delirium.

Conclusion

Post-extubation prophylactic NIT is effective in reducing EF in high-risk patients, especially in the elderly patients. HFNC is an alternative treatment to NIV. Fluid balance, RSBI, ROX index, and delirium are associated with the occurrence of EF.

Mechanisms underlying delirium in patients with critical illness

Delirium is an acute, global cognitive disorder syndrome, also known as acute brain syndrome, characterized by disturbance of attention and awareness and fluctuation of symptoms. Its incidence is high among critically ill patients. Once patients develop delirium, it increases the risk of unplanned extubation, prolongs hospital stay, increases the risk of nosocomial infection, post-intensive care syndrome-cognitive impairment, and even death. Therefore, it is of great importance to understand how delirium occurs and to reduce the incidence of delirium in critically ill patients. This paper reviews the potential pathophysiological mechanisms of delirium in critically ill patients, with the aim of better understanding its pathophysiological processes, guiding the formulation of effective prevention and treatment strategies, providing a basis for clinical medication.

Translation, cultural debugging, and validation of the Chinese version of the Sour Seven Questionnaire: a cross-sectional study

Introduction

Intensive care unit delirium (ICUD) is an acute cerebral dysfunction accompanied by a change of level of consciousness, disorientation, and cognitive dysfunction, typically occurring over a short duration ranging from hours to days and resulting from underlying medical causes. Family members may sometimes detect changes in consciousness earlier than medical staff. The Sour Seven Questionnaire is a tool to assist family members in screening for delirium, but there is currently no Chinese version. This study aimed to translate and cross-culturally debug the Sour Seven Questionnaire and test the effectiveness of the Chinese version in screening for ICUD by family members.

Methods

To create the Chinese version of the questionnaire, the questionnaire was first translated and then culturally debugged through expert consultation and cognitive interviews. Patients and their family members admitted to three ICUs in a Chinese hospital were selected to test the Chinese version of the Sour Seven Questionnaire and the results were compared with those of the validated and recommended Confusion Assessment Method for the intensive care unit (CAM-ICU) assessment.

Results

A total of 190 ICU patients and their families were included in this study. Results of the CAM-ICU assessment showed that 73 (38.4%) patients developed ICUD compared to the 66 (34.7%) using the Chinese version of the Sour Seven Questionnaire, which had a Cohen's kappa coefficient of 0.853, a sensitivity of 0.863, and a specificity of 0.974. The positive predictive value was 0.954 and the negative predictive value was 0.919.

Discussion

The Chinese version of the Sour Seven Questionnaire is a valid assessment tool for helping families screen for ICUD, and it is effective in identifying altered consciousness in patients even during online visits.

Intensive care unit interventions to promote sleep and circadian biology in reducing incident delirium: a scoping review

RATIONALE/OBJECTIVES

Despite plausible pathophysiological mechanisms, research is needed to confirm the relationship between sleep, circadian rhythm and delirium in patients admitted to the intensive care unit (ICU). The objective of this review is to summarise existing studies promoting, in whole or in part, the normalisation of sleep and circadian biology and their impact on the incidence, prevalence, duration and/or severity of delirium in ICU.

METHODS

A sensitive search of electronic databases and conference proceedings was completed in March 2023. Inclusion criteria were English-language studies of any design that evaluated in-ICU non-pharmacological, pharmacological or mixed intervention strategies for promoting sleep or circadian biology and their association with delirium, as assessed at least daily. Data were extracted and independently verified.

RESULTS

Of 7886 citations, we included 50 articles. Commonly evaluated interventions include care bundles (n=20), regulation or administration of light therapy (n=5), eye masks and/or earplugs (n=5), one nursing care-focused intervention and pharmacological intervention (eg, melatonin and ramelteon; n=19). The association between these interventions and incident delirium or severity of delirium was mixed. As multiple interventions were incorporated in included studies of care bundles and given that there was variable reporting of compliance with individual elements, identifying which components might have an impact on delirium is challenging.

CONCLUSIONS

This scoping review summarises the existing literature as it relates to ICU sleep and circadian disruption (SCD) and delirium in ICU. Further studies are needed to better understand the role of ICU SCD promotion interventions in delirium mitigation.

The effect of perioperative dexmedetomidine on postoperative delirium in adult patients undergoing cardiac surgery with cardiopulmonary bypass: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Dexmedetomidine is considered to have neuroprotective effects and may reduce postoperative delirium in both cardiac and major non-cardiac surgeries. Compared with non-cardiac surgery, the delirium incidence is extremely high after cardiac surgery, which could be caused by neuroinflammation induced by surgical stress and CPB. Thus, it is essential to explore the potential benefits of dexmedetomidine on the incidence of delirium in cardiac surgery under CPB.

METHODS

Randomized controlled trials studying the effect of perioperative dexmedetomidine on the delirium incidence in adult patients undergoing cardiac surgery with CPB were considered to be eligible. Data collection was conducted by two reviewers independently. The pre-specified outcome of interest is delirium incidence. RoB 2 was used to perform risk of bias assessment by two reviewers independently. The random effects model and Mantel-Haenszel statistical method were selected to pool effect sizes for each study.

RESULTS

PubMed, Embase, Cochrane Library, and Web of Science were systematically searched from inception to June 28, 2023. Sixteen studies including 3381 participants were included in our systematic review and meta-analysis. Perioperative dexmedetomidine reduced the incidence of postoperative delirium in patients undergoing cardiac surgery with CPB compared with the other sedatives, placebo, or normal saline (RR 0.57; 95% CI 0.41-0.79; P = 0.0009; I2 = 61%).

CONCLUSIONS

Perioperative administration of dexmedetomidine could reduce the postoperative delirium occurrence in adult patients undergoing cardiac surgery with CPB. However, there is relatively significant heterogeneity among the studies. And the included studies comprise many early-stage small sample trials, which may lead to an overestimation of the beneficial effects. It is necessary to design the large-scale RCTs to further confirm the potential benefits of dexmedetomidine in cardiac surgery with CPB.

Impact of beta-blocker usage on delirium in patients with sepsis in ICU: a cross-sectional study

Introduction

Delirium in patients with sepsis can be life-threatening. This study aims to investigate the impact of the use of beta-blockers on the occurrence of delirium in patients with sepsis in the ICU by utilizing a comprehensive dataset.

Methods

This is a cross-sectional study conducted using the data obtained from a single ICU in the USA. Patients diagnosed with sepsis and receiving beta-blockers were compared with those not receiving beta-blockers. Propensity score matching (PSM) and multiple regression analysis were employed to adjust for potential confounders.

Results

Among the 19,660 patients hospitalized for sepsis, the beta-blocker and non-user groups comprised 13,119 (66.73%) and 6,541 (33.27%) patients, respectively. Multivariable logistic regression models revealed a significant reduction of 60% in 7-day delirium for beta-blocker users (OR = 0.40, 95% CI: 0.37-0.43, p < 0.001), for 30-day delirium (OR = 0.32, 95% CI: 0.29-0.35, p < 0.001), and for 90-day delirium (OR = 0.33, 95% CI: 0.30-0.35, p < 0.001). The PSM results further strengthen the validity of these findings. An analysis of safety issues demonstrated that beta-blockers may have an impact on the risk of acute kidney injury. However, following PSM, the results are not considered robust. Furthermore, there was no discernible change in the odds of renal replacement therapy and the length of ICU stays.

Discussion

Our findings suggest a potential protective effect of beta-blockers against delirium in patients with sepsis. Nevertheless, the observational design limits causal inference, necessitating future randomized controlled trials to validate these findings.

Effect of propofol versus midazolam on short-term outcomes in patients with sepsis-associated acute kidney injury

Background

Propofol and midazolam are commonly used sedative drugs in mechanically ventilated patients in the Intensive Care Unit (ICU). However, there is still a lack of relevant studies exploring the influence of midazolam and propofol on the prognosis of patients with Sepsis-associated Acute Kidney Injury (S-AKI).

Patients and methods

A statistical analysis was conducted on 3,745 patients with S-AKI in the Medical Information Mart for Intensive Care IV database. The patients' baseline characteristics were grouped based on the use of either propofol or midazolam as sedatives. Cox proportional hazards models, logistic regression models, and subgroup analyses were used to compare the effects of propofol and midazolam on the short-term prognosis of S-AKI patients, including 30-day mortality, ICU mortality, and duration of mechanical ventilation.

Results

In the statistical analysis, a total of 3,745 patients were included, with 649 patients using midazolam and 3,096 patients using propofol. In terms of the 30-day mortality, compared to patients using midazolam, S-AKI patients using propofol had a lower ICU mortality (hazard ratio = 0.62, 95% confidence interval: 0.52-0.74, p < 0.001), lower 30-day mortality (hazard ratio = 0.56, 95% confidence interval: 0.47-0.67, p < 0.001), and shorter mechanical ventilation time (odds ratio = 0.72, 95% confidence interval: 0.59-0.88, p < 0.001). Kaplan-Meier curves showed lower survival probabilities in the midazolam group (p < 0.001). Subgroup analyses showed that propofol was strongly protective of short-term prognosis in older, male, smaller SOFA score CCI score, no heart failure, and comorbid chronic kidney disease patients with S-AKI.

Conclusion

Compared to midazolam, propofol was considered a protective factor for short-term mortality risk and ICU mortality risk in S-AKI patients. Additionally, S-AKI patients using propofol had a lower risk of requiring prolonged mechanical ventilation. Overall, propofol may be more beneficial for the short-term prognosis of S-AKI patients compared to midazolam.

Effect of Dexmedetomidine on Fluid Resuscitation in Burn-Injured Patients

Fluid creep occurs when resuscitation after extensive burn injury reaches volumes higher than predicted. Since this has been described in patients with high opioid requirements, continuous analgesics and sedatives, including dexmedetomidine, have been avoided during resuscitation. This study sought to describe the impact of dexmedetomidine on fluid resuscitation requirements. This retrospective cohort study included adult patients with burns greater than 20% total body surface area (TBSA) resuscitated between January 2017 and June 2022 at a regional burn center. Patients deceased within 48 hours of burn were excluded. The primary outcome was volume of fluid required in the first 24 and 48 hours postburn. Secondary outcomes were the incidence of fluid-related adverse events within 7 days postburn. A total of 170 patients were included: 55 in the dexmedetomidine cohort and 115 in the control cohort. After propensity matching for variables associated with fluid creep, the dexmedetomidine cohort required 4.2 ± 1.7 mL/kg/%TBSA in the first 24 hours compared to 3.6 ± 1.1 mL/kg/%TBSA in the control cohort (P = 0.03). The difference was no longer significant at 48 hours (P = 0.11). There were no differences in the incidence of acute respiratory distress syndrome, delayed escharotomy/fasciotomy, intra-abdominal hypertension, or renal replacement therapy. Dexmedetomidine exposure during acute resuscitation resulted in increased fluid requirements in the first 24 hours, suggesting it is independently associated with fluid creep; however, this increase was not sustained at 48 hours. Clinical significance of this finding is unclear, as there was no increase in adverse events related to excessive fluid resuscitation between cohorts.

Drugs used for pain management in gastrointestinal surgery and their implications

Pain is the predominant symptom troubling patients. Pain management is one of the most important aspects in the management of surgical patients leading to early recovery from surgical procedures or in patients with chronic diseases or malignancy. Various groups of drugs are used for dealing with this; however, they have their own implications in the form of adverse effects and dependence. In this article, we review the concerns of different pain-relieving medicines used postoperatively in gastrointestinal surgery and for malignant and chronic diseases.

Establishing an Evaluation Indicator System for User Satisfaction With Hypertension Management Apps: Combining User-Generated Content and Analytic Hierarchy Process

BACKGROUND

Hypertension management apps (HMAs) can be effective in controlling blood pressure, but their actual impact is often suboptimal. Establishing a user satisfaction evaluation indicator system for HMAs can assist app developers in enhancing app design and functionality, while also helping users identify apps that best meet their needs. This approach aims to improve the overall effectiveness of app usage.

OBJECTIVE

This study aims to systematically collect data on HMAs and their user reviews in the United States and China. It analyzes app usage patterns and functional characteristics, identifies factors influencing user satisfaction from existing research, and develops a satisfaction evaluation indicator system to provide more accurate recommendations for improving user satisfaction.

METHODS

We conducted a descriptive statistical analysis to assess the development status of HMAs in both countries and applied the task-technology fit model to evaluate whether the app functionalities align with business needs. We separately summarized the factors influencing user satisfaction in both countries from previous research, utilized the analytic hierarchy process to develop an evaluation indicator system for HMA user satisfaction, and calculated satisfaction levels. Based on these findings, we propose improvements to enhance app functionality and user satisfaction.

RESULTS

In terms of current development status, there were fewer HMAs and user reviews in China compared with the United States. Regarding app functional availability, fewer than 5% (4/91) of the apps achieved a demand fulfillment rate exceeding 80% (8/10). Overall, user satisfaction in both countries was low.

CONCLUSIONS

In the United States, user satisfaction was lowest for advertising distribution, data synchronization, and reliability. By contrast, Chinese apps need improvements in cost efficiency and compatibility.

Impact of Pharmacist Intervention on Inappropriate Continuations of Antipsychotics upon ICU Discharge

Background: Transitions of care (TOC) are important to best practices as they are at times prone to medication errors. The intensive care unit (ICU) is an essential location needing effective TOC due to many reasons, but an important one being that certain medications are only indicated there. One example is antipsychotics used for agitation, delirium, and sedation. Objective: To design, implement, and analyze the benefit of a pharmacist intervention on inappropriate antipsychotic continuation from the ICU to another point in care at a small community hospital. Secondary outcomes include patients discharged from the hospital on antipsychotics inappropriately and accepted pharmacist interventions. Methods: This standard of care, prospective with historical control study included adult patients who were ordered a formulary antipsychotic for delirium, agitation, or sedation during their ICU-level of care admission at SSM Health: St. Clare Hospital- Fenton. Results: There were 33 patients in the historical period and 24 in the intervention period. Those in the intervention period were less likely to have a continuation of antipsychotics beyond 72 hours compared to patients in the historical period (16.7% vs 57.6%, P = 0.002). In addition, patients in the intervention period were less likely to have continuation of antipsychotics when discharged to home (12.5% vs 36.4%, P = 0.04). Conclusions: A pharmacist-driven intervention led to a significant decrease in patients continuing antipsychotics upon ICU discharge. This decrease was seen at both 72 hours from patients leaving the ICU and at hospital discharge.

Effect of simulated hearing loss on automatic speech recognition for an android robot-patient

The importance of simulating patient behavior for medical assessment training has grown in recent decades due to the increasing variety of simulation tools, including standardized/simulated patients, humanoid and android robot-patients. Yet, there is still a need for improvement of current android robot-patients to accurately simulate patient behavior, among which taking into account their hearing loss is of particular importance. This paper is the first to consider hearing loss simulation in an android robot-patient and its results provide valuable insights for future developments. For this purpose, an open-source dataset of audio data and audiograms from human listeners was used to simulate the effect of hearing loss on an automatic speech recognition (ASR) system. The performance of the system was evaluated in terms of both word error rate (WER) and word information preserved (WIP). Comparing different ASR models commonly used in robotics, it appears that the model size alone is insufficient to predict ASR performance in presence of simulated hearing loss. However, though absolute values of WER and WIP do not predict the intelligibility for human listeners, they do highly correlate with it and thus could be used, for example, to compare the performance of hearing aid algorithms.

Delirium in the United States: Results From the 2023 Cross-Sectional World Delirium Awareness Day Prevalence Study

BACKGROUND

Delirium is an acute brain dysfunction associated with an increased risk of mortality and future dementia.

OBJECTIVES

To describe the prevalence of clinically documented delirium in the United States on World Delirium Awareness Day 2023.

METHODS

This is a sub-analysis of a prospective, cross-sectional, online, international survey. All health care settings were eligible, with the exception of operating rooms and outpatient clinics. Health care clinicians, administrators, and researchers completed the survey. The primary outcome was the prevalence of clinically documented delirium at 8:00 a.m. and 8:00 p.m. on March 15, 2023. Secondary outcomes were related to health care delivery. Descriptive statistics are reported. Differences between unit types (non-intensive care unit vs intensive care unit) were examined for all outcomes.

RESULTS

Ninety-one hospital units reported on 1318/1213 patients. The prevalence of clinically documented delirium was 16.4% (n = 216/1318) at 8:00 a.m. and 17.9% (n = 217/1213) at 8:00 p.m. (P = 0.316) and significantly differed between age groups, reported discipline, unit, and hospital types. Significant differences were identified between non-intensive care unit and intensive care unit settings in the use of delirium-related protocols, nonpharmacologic and pharmacologic management, educational processes, and barriers to evidence-based delirium care.

CONCLUSIONS

To our knowledge, this is the first epidemiologic survey of clinically documented delirium across two time points in the United States. Delirium remains a significant burden and challenge for health care systems. The high percentage of units using delirium management protocols suggests administrator and clinician awareness of evidence-based strategies for its detection and mitigation. We provide recommendations for future studies and quality improvement projects to improve clinical recognition and management of delirium.

ICU nurses' practice and intention to implement early mobilization: A multi-centre cross-sectional survey

BACKGROUND

Early mobilization (EM) is acknowledged for its safety and benefits in the recovery of critically ill patients, yet its implementation in intensive care units (ICU) remains inconsistently aligned with established guidelines. This discrepancy highlights a gap between theoretical endorsement and practical application. While barriers to EM have been extensively studied, the intentions and perceived practices of ICU nurses towards EM, especially in certain geographical regions, have not been adequately understood.

AIM

The objective of this study is to assess the perceptions, actual practices and intentions of ICU nurses regarding the implementation of EM for patients in the ICU setting.

STUDY DESIGN

A cross-sectional, multi-centre, survey-based study.

RESULTS

The study collected data through an electronic questionnaire from 227 ICU nurses across eight hospitals in Beijing, China, concerning their experiences, practices and intentions related to EM. The survey response rate was 50% (114 of 227), indicating a moderate level of engagement by the target population. Among the surveyed participants, 68.7% (n = 156) reported having experience with EM for critically ill patients. Of these experienced nurses, 49.3% (n = 77) indicated they carried out EM less frequently than once per week, while only 29.5% (n = 46) reported dedicating more than 20 min to EM activities per patient. Only 24.2% (n = 55) of participants confirmed the presence of specific EM guidelines in their workplace. Notably, guideline adherence could be influenced by the patient's condition severity, which may affect how these protocols are applied. Notably, the approach and frequency of EM practices showed significant variation across different ICUs. A substantial majority (75%, n = 170) of participants expressed a strong intention towards implementing EM, correlating significantly with factors such as having a higher education level (bachelor's degree or higher), receiving departmental support, encountering fewer perceived barriers, and belonging to specific departments like respiratory (SICU) and surgery (RICU). The EM guidelines mentioned by participants were primarily focused on specific protocols and guidance, highlighting the emphasis on structured approaches to EM in their clinical settings.

CONCLUSIONS

Despite the recognized experience with EM among ICU nurses, there is a notable divergence between their practices and the recommendations outlined in EM guidelines. This study underscores the need for the establishment of clear, actionable guidelines, alongside the provision of targeted educational programmes and robust support systems, to foster the consistent and effective implementation of EM in ICU settings.

RELEVANCE TO CLINICAL PRACTICE

This study underscores the clinical relevance of EM in ICU settings, advocating for the development of precise EM guidelines to improve patient outcomes.

An online delirium detection tool: Cross-cultural adaptation of a Chinese version of the Family Confusion Assessment Method

BACKGROUND

Intensive care unit (ICU) delirium is a common complication in older critically ill patients that has a significant impact. The Family Confusion Assessment Method (FAM-CAM) is a vital tool for assisting family members in identifying delirium; however, no study has yet been reported on the Chinese version of the scale.

OBJECTIVES

The objective of this study was to translate the FAM-CAM into a Chinese version and to verify its effectiveness for delirium detection in an online patient visit setting.

METHODS

This was a cross-sectional study. The FAM-CAM was translated to Chinese according to the International Society for Pharmacoeconomics and Outcomes Research guidelines. Patients and family members were recruited to participate in delirium assessments in three ICUs of one hospital. Family members then used the Chinese version of the FAM-CAM to assess for delirium via online visitation, and ICU nurses assessed patients for delirium using the Intensive Care Delirium Screening Checklist (ICDSC). Results were then compared between family members' and nurses' assessments.

RESULTS

Overall, 190 critically ill patients and 190 family members were included, of whom 117 (61.6%) were assessed for delirium using the Intensive Care Delirium Screening Checklist. The Cohen's kappa coefficient between the Intensive Care Delirium Screening Checklist and FAM-CAM was 0.759 (P < 0.01). The sensitivity of the Chinese version of the FAM-CAM was 0.880, specificity was 0.890, positive predictive value was 0.928, negative predictive value was 0.823, and area under the receiver operating characteristic curve was 0.881 (95% confidence interval: 0.872-0.935, P < 0.01).

CONCLUSION

The Chinese version of the FAM-CAM was shown to effectively help families detect delirium and was suggested as a crucial tool for assisting ICU nurses in the early identification of delirium. This tool may effectively be used to assess delirium during online visits.

Codesign of a Quality Improvement Tool for Adults With Prolonged Critical Illness: A Modified Delphi Consensus Study

OBJECTIVES

Increasing numbers of patients experience a prolonged stay in intensive care. Yet existing quality improvement (QI) tools used to improve safety and standardize care are not designed for their specific needs. This may result in missed opportunities for care and contribute to worse outcomes. Following an experience-based codesign process, our objective was to build consensus on the most important actionable processes of care for inclusion in a QI tool for adults with prolonged critical illness.

DESIGN

Items were identified from a previous systematic review and interviews with former patients, their care partners, and clinicians. Two rounds of an online modified Delphi survey were undertaken, and participants were asked to rate each item from 1 to 9 in terms of importance for effective care; where 1-3 was not important, 4-6 was important but not critical, and 7-9 was critically important for inclusion in the QI tool. A final consensus meeting was then moderated by an independent facilitator to further discuss and prioritize items.

SETTING

Carried out in the United Kingdom.

PATIENTS/SUBJECTS

Former patients who experienced a stay of over 7 days in intensive care, their family members and ICU staff.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We recruited 116 participants: 63 healthcare professionals (54%), 45 patients (39%), and eight relatives (7%), to Delphi round 1, and retained 91 (78%) in round 2. Of the 39 items initially identified, 32 were voted "critically important" for inclusion in the QI tool by more than 70% of Delphi participants. These were prioritized further in a consensus meeting with 15 ICU clinicians, four former patients and one family member, and the final QI tool contains 25 items, including promoting patient and family involvement in decisions, providing continuity of care, and structured ventilator weaning and rehabilitation.

CONCLUSIONS

Using experience-based codesign and rigorous consensus-building methods we identified important content for a QI tool for adults with prolonged critical illness. Work is underway to understand tool acceptability and optimum implementation strategies.

A multicentre point prevalence study of nocturnal hours awake and enteral pharmacological sleep aids in patients admitted to Australian and New Zealand intensive care units

Objective

Critically ill patients suffer disrupted sleep. Hypnotic medications may improve sleep; however, local epidemiological data regarding the amount of nocturnal time awake and the use of such medications is needed.

Design

Point prevalence study.

Setting

Adult ICUs in Australia and New Zealand.

Participants

All adult patients admitted to participating Intensive Care Units (ICUs) on the study day.

Main outcome measures

Time awake overnight (22:00-06:00) was determined by structured nurse observation. The use of enterally administered sedative-hypnotic drugs prior to and during ICU admission was recorded, as was the use of a unit policy and non-pharmacological sleep promotion strategies.

Results

Data were available for 532 patients admitted to 40 ICUs (median age 60 years, 336 (63.2%) male, and 222 (41.7%) invasively ventilated). Forty-eight patients (9.0%) received an enteral pharmacological sleep aid, of which melatonin (28, 5.2%) was most frequently used. Patients not invasively ventilated were observed to be awake overnight for a median of 4.0 h (interquartile range (IQR): 2.5, 5.5), with no difference in those receiving an enteral hypnotic (p = 0.9). Non-pharmacological sleep aids were reportedly not offered or available for 52% (earplugs) and 63% of patients (eye masks). Only 7 (17.5%) participating ICUs had a policy informing sleep-optimising interventions.

Conclusions

Patients not receiving invasive ventilation appeared to spend many nocturnal hours awake. Pharmacological sleep aid administration was not associated with a greater observed time asleep. Most patients did not receive any non-pharmacological aid, and most ICUs did not have a local guideline or unit policy on sleep promotion.

Practices of the ABCDEF care bundle in intensive care units as reported by nurses: A cross-sectional study from Turkey

BACKGROUND

Recent critical care guidelines recommended the evidence-based ABCDEF care bundle for intensive care unit (ICU) patients. However, limited information is available on the implementation of the bundle in Turkish ICUs.

AIM

To assess the current practices of the ABCDEF care bundle as reported by ICU nurses.

STUDY DESIGN

A cross-sectional study using a web-based survey was conducted. Researchers invited nurses with at least 1 year of ICU experience to participate by sending the link to the research questionnaires they created in Google Forms to the one ICU nurse association and one communication group of which they are members.

RESULTS

A total of 342 ICU nurses completed the survey. Although 92% of the participants performed pain assessments in their ICUs, 52.7% reported not using protocols. Based on the responses of the nurses, spontaneous awakening and breathing trials are performed in 88.8% and 92.4%, respectively, of ICUs. Fewer than half of the participants reported following a sedation protocol in their ICUs. Only 54.7% of ICU nurses surveyed reported routinely monitoring patients for delirium. It was reported that early mobilization was practised in 68.7% of ICUs, but non-ventilated patients were mobilized more frequently (70.2%), and 9.7% of ICUs had mobilization teams. Family members were actively involved in 95% of ICUs; however, 9.7% used dedicated staff to support families and 3.5% reported that their unit was open 24 h/day for visits.

CONCLUSIONS

While the implementation of most pain and sedation evaluations in ICUs were reported by nurses, many of them did not use structured delirium assessments. There is a need to encourage early mobilization programs and family participation.

RELEVANCE TO CLINICAL PRACTICE

Health institutions can improve patient care and outcomes by establishing and standardizing a protocol for each component of the ABCDEF care bundle in ICUs.

Patient, Practice, and Organizational Factors Associated With Early Mobility Performance in Critically Ill Adults

BACKGROUND

Adoption of early mobility interventions into intensive care unit (ICU) practice has been slow and varied.

OBJECTIVES

To examine factors associated with early mobility performance in critically ill adults and evaluate factors' effects on predicting next-day early mobility performance.

METHODS

A secondary analysis of 66 ICUs' data from patients admitted for at least 24 hours. Mixed-effects logistic regression modeling was done, with area under the receiver operating characteristic curve (AUC) calculated.

RESULTS

In 12 489 patients, factors independently associated with higher odds of next-day mobility included significant pain (adjusted odds ratio [AOR], 1.16; 95% CI, 1.09-1.23), documented sedation target (AOR, 1.09; 95% CI, 1.01-1.18), performance of spontaneous awakening trials (AOR, 1.77; 95% CI, 1.59-1.96), spontaneous breathing trials (AOR, 2.35; 95% CI, 2.14-2.58), mobility safety screening (AOR, 2.26; 95% CI, 2.04-2.49), and prior-day physical/occupational therapy (AOR, 1.44; 95% CI, 1.30-1.59). Factors independently associated with lower odds of next-day mobility included deep sedation (AOR, 0.44; 95% CI, 0.39-0.49), delirium (AOR, 0.63; 95% CI, 0.59-0.69), benzodiazepine administration (AOR, 0.85; 95% CI, 0.79-0.92), physical restraints (AOR, 0.74; 95% CI, 0.68-0.80), and mechanical ventilation (AOR, 0.73; 95% CI, 0.68-0.78). Black and Hispanic patients had lower odds of next-day mobility than other patients. Models incorporating patient, practice, and between-unit variations displayed high discriminant accuracy (AUC, 0.853) in predicting next-day early mobility performance.

CONCLUSIONS

Collectively, several modifiable and nonmodifiable factors provide excellent prediction of next-day early mobility performance.

Extraction of ketamine and dexmedetomidine by extracorporeal life support circuits★

BACKGROUND

Patients supported with extracorporeal life support (ECLS) circuits such as ECMO and CRRT often require high doses of sedatives and analgesics, including ketamine and dexmedetomidine. Concentrations of many medications are affected by ECLS circuits through adsorption to the circuit components, dialysis, as well as the large volume of blood used to prime the circuits. However, the impact of ECLS circuits on ketamine and dexmedetomidine pharmacokinetics has not been well described. This study determined ketamine and dexmedetomidine extraction by extracorporeal circuits in an ex-vivo system.

METHODS

Medication was administered at therapeutic concentration to blood-primed, closed-loop ex-vivo ECMO and CRRT circuits. Drug concentrations were measured in plasma, hemofiltrate, and control samples at multiple time points throughout the experiments. At each sample time point, the percentage of drug recovery was calculated.

RESULTS

Ketamine plasma concentration in the ECMO and CRRT circuits decreased rapidly, with 43.8% recovery (SD = 0.6%) from ECMO circuits after 8 h and 3.3% (SD = 1.8%) recovery from CRRT circuits after 6 h. Dexmedetomidine was also cleared from CRRT circuits, with 20.3% recovery (SD = 1.8%) after 6 h. Concentrations of both medications were very stable in the control experiments, with approximately 100% drug recovery of both ketamine and dexmedetomidine after 6 h.

CONCLUSION

Ketamine and dexmedetomidine concentrations are significantly affected by ECLS circuits, indicating that dosing adjustments are needed for patients supported with ECMO and CRRT.

Intensive care nurses' perceptions and awareness of delirium and delirium prevention guidelines

BACKGROUND

Delirium is an acute and fluctuating disturbance of cognition and is a common occurrence in critically ill patients. It is a manifestation of an acute brain dysfunction often attributed to higher survival rates and a subsequently aging population. Intensive Care Unit (ICU) treatment and survival often contributes towards development of delirium, and lack of or inappropriate management can translate into the development of long-term psychological effects that last even after discharge. While a lot is already known about this topic, and several assessment tools exist, these are not being consistently used by ICU nurses and as a result delirium often goes unrecognized, with unwarranted consequences.

AIMS

The study aimed to explore the perception of delirium among ICU nurses, and the extent of their awareness about guidelines to assess and prevent delirium in ICU patients. It also sought to understand the application of delirium guidelines in ICU practice.

STUDY DESIGN

A quantitative, exploratory, self-reporting survey was conducted among 145 ICU nurses from one critical care unit in the Republic of Ireland.

RESULTS

The overall response rate was 71% (103/145). Most nurses (85%) who participated in this survey believed delirium was expected. However, only 45% acknowledged it is a complication. Only 31% of nurses monitored delirium using a validated scale and few observed this as a part of routine care. Most nurses had received education; however, this did not translate to their clinical practice.

CONCLUSIONS

Guidelines on managing delirium may not be routinely implemented in the ICU settings of hospitals in the Republic of Ireland.

RELEVANCE TO CLINICAL PRACTICE

As the findings suggest, a gap exists between theory and practice, necessary revision of policy or creating a new policy, supplemental educational sessions such as bedside sessions, e-learning module, study day or seminars need to be organized to improve nurses' awareness related to delirium and delirium prevention guidelines.

Measuring pain or discomfort during routine nursing care in lightly sedated mechanically ventilated intensive care patients: A prospective preliminary cohort study

BACKGROUND

Pain is routinely measured on mechanically ventilated ICU patients. However, the tools used are not designed to discriminate between pain and non-pain discomfort, a distinction with therapeutic implications.

OBJECTIVES

To evaluate whether clinical measurement tools can discern both pain and non-pain discomfort.

METHODS

A prospective observational cohort study was conducted in a General ICU at a tertiary Medical Center in Israel. The Behavior Pain Scale (BPS) and Visual Analog Scale (VAS) of Discomfort were simultaneously assessed by a researcher and bedside nurse on thirteen lightly sedated patients during 71 routine nursing interventions in lightly sedated, mechanically ventilated, adult patients. Patients were asked whether they were in pain due to these interventions.

RESULTS

Statistically significant increases from baseline during interventions were observed [median change: 1.00 (-1-5), 1.5(-4-8.5), p < 0.001] as measured by BPS and VAS Discomfort Scale, respectively. BPS scores ranged between 4 and 6 when the majority (53 %) of the patients replied that they had no pain but were interpreted by the clinicians as discomfort. Endotracheal suctioning caused the greatest increase in BPS and VAS, with no statistically significant differences in BPS and VAS Discomfort Scale scores whether patients reported or did not report pain. A BPS>6 had a higher sensitivity and specificity to reported pain (accuracy of 76 %) compared to a BPS of 4-6.

CONCLUSIONS

Standard assessments are sensitive to pain caused by routine nursing care interventions. However, this study presents evidence that among lightly sedated ICU patients, moderate BPS scores could also measure non-pain discomfort. ICU nurses should be aware that signs of unpleasantness measured by a pain scale could reflect non-pain discomfort.

Delirium and Coronavirus Disease 2019: Looking Back, Moving Forward

During the coronavirus disease 2019 pandemic, crisis changes in clinical care increased rates of delirium in the intensive care unit (ICU). Deep sedation, unfamiliar environments with visitor restrictions, and such factors due to high workload and health system strain contributed to the occurrence of delirium doubling in the ICU. As the pandemic wanes, health care systems and ICU leadership must emphasize post-pandemic recovery, integrating lessons learned about delirium management, evidence-based care, and family involvement. Strategies to empower clinicians, creatively deliver care, and integrate families pave the way forward for a more holistic approach to patient care in the post-pandemic era.

Nurses' experiences of caring for nursing care-dependent ICU patients: A qualitative study

BACKGROUND

Nursing care dependency is a key, yet under-studied, nursing phenomenon. Patients in intensive care units are highly dependent on nursing care. Patients find dependency challenging, experiencing feelings of powerlessness and shame. The nurse-patient care relationship can influence patients' perception of dependency. Understanding how nurses experience their care for dependent patients is crucial, as nurses might not always grasp the impact of their actions on patients' dependency experiences.

AIM

To explore and interpret ICU nurses' perceptions of patients' nursing care dependency and their experiences in caring for nursing care-dependent patients.

STUDY DESIGN

A qualitative interpretative phenomenological study inspired by Merleau-Ponty's philosophical stance was conducted using focus groups with nurses who had been caring for adult patients for at least 6 months in ICUs of two hospitals. Data analysis followed Smith et al.'s guidance. Researchers immersed themselves in the transcripts, noted individual's experiences before transitioning to shared insights, coded significant phrases and generated themes and superordinate themes.

RESULTS

Four focus groups were conducted with 18 nurses with widely ranging ages and work experience. Four superordinate themes emerged: 'Time and context define dependency', 'Empathetic relationships help nurses understand patients' experience of dependency', 'Trusting nurse-patient relationships change the dependency experience' and 'Nurses' skills help patients to recover independence'.

CONCLUSION

This study increases critical care nurses' awareness of the overlooked phenomenon of caring for nursing care dependent patients and offers them an opportunity to reflect on their care for dependent patients and adapt it to patients' experiences. Further studies are needed with nurses and patients in different ICUs, cultures and countries, to gain a broader picture of experiences of nursing care dependency.

RELEVANCE TO CLINICAL PRACTICE

ICU nurses need strong relational skills to offer high-quality care for dependent patients, facilitating meaningful nurse-patient relationships based on empathy and trust. These relationships can significantly impact the patient's experience of dependence.

Adaptation and validation of the Physical Restraint-Theory of Planned Behaviour Questionnaire to the paediatric context

BACKGROUND

Physical restraint is applied in pediatric intensive care units to carry out certain painful procedures and to ensure the maintenance and continuity of life support devices. There is a need to analyse the factors that influence the behaviour or intention to use physical restraint.

AIM

To create and test psychometrically a paediatric version of the Physical Restraint-Theory of Planned Behaviour Questionnaire to assess paediatric critical care nurses' intention to use physical restraint.

STUDY DESIGN

A psychometric study. Five medical-surgical Paeditric Intensive care Units from five hospitals in Spain. The study took place in three phases. In phase 1, the questionnaire was adapted. In phase 2, the content validity of each item was determined, and a pilot test was conducted. In phase 3, we administered the questionnaire and determined its psychometric properties.

RESULTS

The assessment of the intention to use physical restraint was extended to all critical paediatric patients, two items were eliminated from the initial questionnaire, four new items were included, and the clinical scenarios of the intention subscale were expanded from three to six. Overall content validity index for the full instrument of 0.96 out of 1. The Paediatric Physical Restraint-Theory of Planned Behaviour Questionnaire is made up of four subscales (attitude, subjective norms (SN), perceived behavioural control (PBC), and intention) subdivided into 7 factors and 51 items. The internal consistency for the attitude subscale obtained a Cronbach's Alpha of 0.80 to 0.73, for the SN it was 0.72 to 0.89, for the PBC it was from 0.80 to 0.73 and for the intention subscale it was 0.75.

CONCLUSIONS

The Paediatric Physical Restraint-Theory of Planned Behaviour Questionnaire is an instrument composed of seven factors and 51 items that validly and reliably assesses the intention of paediatric nurses to apply PR in PICUs.

RELEVANCE FOR CLINICAL PRACTICE

Having this instrument will help health centres move towards restraint-free care by allowing managers to assess professionals' attitudes, beliefs, and intentions around the use of PR in PICUs.
