Evaluating the Accuracy of Off-Label Placement of Pulse Oximetry Sensors in Comparison to On-Label Placement in the Adult Cardiac Intensive Care Unit Patient Population.

Continuous pulse oximetry (Spo2) is a commonly utilized tool to obtain an indirect, noninvasive measurement of hemoglobin oxygen saturation. Difficulty obtaining measurement with Spo2 sensors can lead nurses to try off-label sites until they find placement that provides a signal. Currently, there is limited evidence to support this application. The purpose of this study was to evaluate the accuracy of off-label placement of pulse oximetry sensors in comparison to on-label placement in adult cardiac intensive care patients. Data were collected on 24 participants. At the time of a medically necessary arterial blood gas laboratory draws, 4 Spo2 measurements were gathered from an on-label finger sensor, an off-label finger sensor, an on-label ear sensor, and an off-label ear sensor. Results were analyzed using 4 Pearson correlation coefficients, Bland-Altman plots, and 2 linear mixed-effect models. Our study found that while both our on-label finger and off-label finger pulse oximetry sensor overestimated when compared to the arterial hemoglobin saturation (gold standard), there was greater overestimation found with the off-label placement. Though there was not a significant difference observed between the ear probe on the nose and the gold standard, figures examining off-label ear probe and gold standard measures show that, in lower ranges of oxygen saturation, the off-site probe substantially overestimates true oxygen saturation, while in higher ranges of oxygen saturation, the off-site ear probe underestimates true oxygen saturation. No changes should be made to the current practice of using pulse oximetry sensor placement.

Two Weeks Versus One Week of Maximal Patient-Intensivist Continuity for Adult Medical Intensive Care Patients: A Two-Center Target Trial Emulation.

To compare outcomes for 2 weeks vs. 1 week of maximal patient-intensivist continuity in the ICU. Retrospective cohort study. Two U.S. urban, teaching, medical ICUs where intensivists were scheduled for 2-week service blocks: site A was in the Midwest and site B was in the Northeast. Patients 18 years old or older admitted to a study ICU between March 1, 2017, and February 28, 2020. None. We applied target trial emulation to compare admission during an intensivist's first week (as a proxy for 2 wk of maximal continuity) vs. admission during their second week (as a proxy for 1 wk of maximal continuity). Outcomes included hospital mortality, ICU length of stay, and, for mechanically ventilated patients, duration of ventilation. Exploratory outcomes included imaging, echocardiogram, and consultation orders. We used inverse probability weighting to adjust for baseline differences and random-effects meta-analysis to calculate overall effect estimates. Among 2571 patients, 1254 were admitted during an intensivist's first week and 1317 were admitted during a second week. At sites A and B, hospital mortality rates were 25.8% and 24.2%, median ICU length of stay were 4 and 2 days, and median mechanical ventilation durations were 3 and 3 days, respectively. There were no differences in adjusted mortality (odds ratio [OR], 1.01 [95% CI, 0.96-1.06]) or ICU length of stay (-0.25 d [-0.82 d to +0.32 d]) for 2 weeks vs. 1 week of maximal continuity. Among mechanically ventilated patients, there were no differences in adjusted mortality (OR, 1.00 [0.87-1.16]), ICU length of stay (+0.06 d [-0.78 d to +0.91 d]), or duration of mechanical ventilation (+0.37 d [-0.46 d to +1.21 d]) for 2 weeks vs. 1 week of maximal continuity. Two weeks of maximal patient-intensivist continuity was not associated with differences in clinical outcomes compared with 1 week in two medical ICUs.

The frequency of pressure injury in level 3 intensive care units and determination of risk factors: A cross-sectional study

AimThis study was carried out to determine the prevalence of pressure injury and risk factors in patients hospitalized in a university hospital's level 3 intensive care unit. DesignIt is a descriptive, prospective, observational type study. MethodThe sample of the study consisted of 176 patients aged 18 and over who were admitted to the intensive care units of a University Hospital for at least 24 h. Patient Information Form and Braden Risk Assessment Scale, Glasgow Coma Scale were used to collect data. IBM SPSS Statistics 20 program was used to analyze the data. ResultsPresence of chronic disease in the development of pressure injury (22.7%), high-risk patients according to the Glasgow Coma Scale (21%), high-risk patients according to the Braden Risk Assessment Scale (84.2%), low hemoglobin (31%), low albumin levels (32.4%) and duration of stay in the intensive care unit until the day of evaluation were found to be independent risk factors (p < 0.05). The prevalence of pressure injury was determined to be 32.4%, and the rate of pressure injury due to medical devices was 7.4%. ConclusionPressure injuries are still common in adult intensive care patients. In terms of patient safety, it is important to give more space to care standards and awareness-raising research and training to prevent pressure injuries.

Assessing Discomfort in American Adult Intensive Care Patients.

While in the intensive care unit, critically ill patients experience a myriad of distressing symptoms and stimuli leading to discomfort, a negative emotional and/ or physical state that arises in response to noxious stimuli. Appropriate management of these symptoms requires a distinct assessment of discomfort-causing experiences. To assess patient-reported discomfort among critically ill patients with the English-language version of the Inconforts des Patients de REAnimation questionnaire, and to explore relationships between demographic and clinical characteristics and overall discomfort score on this instrument. This study had a cross-sectional, descriptive, single-cohort design. The convenience sample consisted of alert and oriented patients aged 18 years or older who had been admitted to intensive care units at a Midwestern tertiary referral hospital and were invited to participate. An 18-item questionnaire on physiological and psychological stimuli inducing discomfort was administered once. Each item was scored from 0 to 10, with the total possible discomfort score ranging from 0 to 100. Descriptive statistics were used to analyze participants' demographic and clinical characteristics and questionnaire responses. A total of 180 patients were enrolled. The mean (SD) overall discomfort score was 32.9 (23.6). The greatest sources of discomfort were sleep deprivation (mean [SD] score, 4.0 [3.4]), presence of perfusion catheters and tubing (3.4 [2.9]), thirst (3.0 [3.3]), and pain (3.0 [3.0]). Intensive care unit patients in this study reported mild to moderate discomfort. Additional research is needed to design and test interventions based on assessment of specific discomfort-promoting stimuli to provide effective symptom management.

Assessing fluid responsiveness with ultrasound in the neonatal intensive care setting: the mini-fluid challenge.

The mini-fluid challenge (MFC) can guide individualised fluid therapy and prevent fluid overload and associated morbidity in adult intensive care patients. This ultrasound test is based on the Frank-Starling principles to assess dynamic fluid responsiveness, but limited MFC data exists for newborns.This brief report describes the feasibility of the MFC in 12 preterm infants with late onset sepsis and 5 newborns with other pathophysiology. Apical views were used to determine the changes in left ventricular stroke volume before and after a 3ml/kg fluid bolus was given over 5min. Four out of the 17 infants were fluid responsive, defined as a post-bolus increase in stroke volume of 15% or more. Conclusion: The MFC was feasible and followed the physiological principles of stroke volume and extravascular lung water changes and 24% were fluid responsive. The MFC could enable future studies to examine whether adding fluid responsiveness to guide fluid therapy in newborns can reduce the risk of fluid overload. What is Known: • Fluid overload is associated with morbidity and mortality. • The mini-fluid challenge (MFC) provides a personalised approach to fluid therapy. What is New: • The MFC is feasible in newborns. • The MFC followed the physiological principles of stroke volume and extravascular lung water changes.

Continuous visualization and validation of pain in critically ill patients using artificial intelligence: a retrospective observational study

Machine learning tools have demonstrated viability in visualizing pain accurately using vital sign data; however, it remains uncertain whether incorporating individual patient baselines could enhance accuracy. This study aimed to investigate improving the accuracy by incorporating deviations from baseline patient vital signs and the concurrence of the predicted artificial intelligence values with the probability of critical care pain observation tool (CPOT) ≥ 3 after fentanyl administration. The study included adult patients in intensive care who underwent multiple pain-related assessments. We employed a random forest model, utilizing arterial pressure, heart rate, respiratory rate, gender, age, and Richmond Agitation–Sedation Scale score as explanatory variables. Pain was measured as the probability of CPOT scores of ≥ 3, and subsequently adjusted based on each patient's baseline. The study included 10,299 patients with 117,190 CPOT assessments. Of these, 3.3% had CPOT scores of ≥ 3. The random forest model demonstrated strong accuracy with an area under the receiver operating characteristic curve of 0.903. Patients treated with fentanyl were grouped based on CPOT score improvement. Those with ≥ 1-h of improvement after fentanyl administration had a significantly lower pain index (P = 0.020). Therefore, incorporating deviations from baseline patient vital signs improved the accuracy of pain visualization using machine learning techniques.

Amantadine for NeuroenhaNcement in acutE patients Study - a protocol for a prospective pilot proof of concept phase IIb study in intensive and intermediate care unit patients (ANNES)

BackgroundPersisting coma is a common complication in (neuro)intensive care in neurological disease such as acute ischemic stroke, intracerebral hemorrhage or subarachnoid hemorrhage. Amantadine acts as a nicotinic receptor antagonist, dopamine receptor agonist and non-competitive N-Methyl-D-aspartate receptor antagonist. Amantadine is a long-known drug, originally approved for treatment of influenza A and Parkinson`s Disease. It has been proven effective in improving vigilance after traumatic brain injury. The underlying mechanisms remain largely unknown, albeit anti-glutamatergic and dopaminergic effects might be most relevant. With limited evidence of amantadine efficacy in non-traumatic pathologies, the aim of our study is to assess the effects of amantadine for neuroenhancement in non-traumatic neurointensive patients with persisting coma.MethodsAn investigator-initiated, monocenter, phase IIb proof of concept open-label pilot study will be carried out. Based on the Simon design, 43 adult (neuro)intensive care patients who meet the clinical criteria of persisting coma not otherwise explained and < 8 points on the Glasgow Coma Scale (GCS) will be recruited. Amantadine will be administered intravenously for five days at a dosage of 100 mg bid. The primary endpoint is an improvement of at least 3 points on the GCS. If participants present as non-responders (increase < 3 points or decrease on the GCS) within the first 48 h, the dosage will be doubled from day three to five. Secondary objectives aim to demonstrate that amantadine improves vigilance via alternative scales. Furthermore, the incidence of adverse events will be investigated and electroencephalography (EEG) will be recorded at baseline and end of treatment.DiscussionThe results of our study will help to systematically assess the clinical utility of amantadine for treatment of persisting coma in non-traumatic brain injury. We expect that, in the face of only moderate treatment risk, a relevant number of patients will benefit from amantadine medication by improved vigilance (GCS increase of at least 3 points) finally leading to a better rehabilitation potential and improved functional neurological outcome. Further, the EEG data will allow evaluation of brain network states in relation to vigilance and potentially outcome prediction in this study cohort.Trial RegistrationNCT05479032.

Monitoring delirium in the intensive care unit: Diagnostic accuracy of the CAM-ICU tool when performed by certified nursing assistants – A prospective multicenter study

BackgroundMonitoring delirium in critically ill patients is recognized as a major challenge. Although involving certified nursing assistants could be a valuable help in this field, such strategy has never been formally investigated. ObjectivesFollowing theoretical training, we conducted a prospective multicenter study assessing the diagnostic accuracy of a CAM-ICU delirium screening strategy performed by CNAs in clinical settings, compared to parallel blinded evaluations conducted by nurses and physicians. MethodsFrom October 2020 to June 2022, adult intensive care patients admitted in three French University teaching hospitals with Richmond Agitation Sedation Scale ≥−2 were independently assessed for delirium by the three members of the care team (clinical nursing assistant, nurse and physician) using CAM-ICU in a random order. Physician’s assessment served as the reference standard for comparisons. ResultsWe analyzed results from 268 triplets of CAM-ICU assessments performed sequentially on 203 patients. Prevalence of delirium was 22%. Compared to physician's assessments, clinical nursing assistants demonstrated a sensitivity (Se) of 88% CI95% [80–96] and a specificity (Sp) of 95% [92–98] in detecting delirium. There was no significant difference in the performance of clinical nursing assistants and nurses (Se = 90 % [82–97] p = 0.77, Sp = 98 % [95–100] p = 0.19). We observed high agreement between results obtained by physicians and clinical nursing assistants (ĸ = 0.82) and clinical nursing assistants performance remained consistent in the subgroups at higher risk of delirium. ConclusionEvaluation of the CAM-ICU by clinical nursing assistants is feasible and should be seen as an opportunity to increase routine monitoring of delirium in intensive care patients. Implication for Clinical PracticeDelirium is a severe and underestimated complication of intensive care unit stay. This study results demonstrate the great performance of trained clinical nursing assistants in detecting delirium using the CAM-ICU. Further research is needed to define the most effective role for clinical nursing assistants in the routine management of delirium in intensive care patients.

Evaluation of evolving sepsis screening criteria in discriminating suspected sepsis and mortality among adult patients admitted to the intensive care unit

BackgroundInstitutions struggle with successful use of sepsis alerts within electronic health records. ObjectiveTest the association of sepsis screening measurement criteria in discrimination of mortality and detection of sepsis in a large dataset. DesignRetrospective, cohort study using a large United States (U.S.) intensive care database. The Institutional Review Board exempt status was obtained from Kansas University Medical Center Human Research Protection Program (10-1-2015). Setting334 U.S. hospitals participating in the eICU Research Institute. ParticipantsNine hundred twelve thousand five hundred and nine adult intensive care admissions from 183 hospitals. MethodsExposures included: systemic inflammatory response syndrome criteria ≥ 2 (Sepsis-1); systemic inflammatory response syndrome criteria with organ failure criteria ≥ 3.5 points (Sepsis-2); and sepsis-related organ failure assessment score ≥ 2 and quick score ≥ 2 (Sepsis-3). Discrimination of outcomes was determined with/without (adjusted/unadjusted) baseline risk exposure to a model. The receiver operating characteristic curve (AUROC) and odds ratios (ORs) for each decile of baseline risk of sepsis or death were assessed. ResultsWithin the eligible cohort of 912,509, a total of 86,219 (9.4 %) patients did not survive their hospital stay and 186,870 (20.5 %) met the definition of suspected sepsis. For suspected sepsis discrimination, Sepsis-2 (unadjusted AUROC 0.67, 99 % CI: 0.66–0.67 and adjusted AUROC 0.77, 99 % CI: 0.77–0.77) outperformed Sepsis-3 (SOFA unadjusted AUROC 0.61, 99 % CI: 0.61–0.61 and adjusted AUROC 0.74, 99 % CI: 0.74–0.74) (qSOFA unadjusted AUROC 0.59, 99 % CI: 0.59–0.60 and adjusted AUROC 0.73, 99 % CI: 0.73–0.73). Sepsis-2 also outperformed Sepsis-1 (unadjusted AUROC 0.58, 99 % CI: 0.58–0.58 and adjusted AUROC 0.73, 99 % CI: 0.73–0.73). In between differences of AUROCs were statistically significantly different. Sepsis-2 ORs were higher for the outcome of suspected sepsis when considering deciles of risk than the other measurement systems. Conclusions and relevanceSepsis-2 outperformed other systems in suspected sepsis detection and was comparable to SOFA in prognostic accuracy of mortality in adult intensive care patients.

739 A Review of Current Methicillin-Resistant Staphylococcus Aureus Decolonization Practices in a Pediatric Burn Population

Abstract Introduction Methicillin-resistant staphylococcus aureus (MRSA) infections can result in severe sequela including death. Evidence-based practice guidelines exist for the universal decolonization of adult intensive care (ICU) patients. Evidence has not been established in the pediatric population, resulting in a knowledge gap regarding MRSA decolonization in children. Our practice is to test all patients upon admission for MRSA. Regardless of results, due to the immunocompromise of burn patients, all admissions are placed on a decolonization protocol that includes mupirocin ointment intranasally twice daily for five days. The repeated intranasal swabbing causes both discomfort and psychological distress for our pediatric patients. The purpose of this study was to evaluate current practice and the incidence of MRSA bacteremia in our pediatric population. Methods This was a retrospective review of all pediatric patients admitted to our center between January 2018 and August 2022. Patients who had mupirocin ordered for decolonization (YO) were compared to those who did not (NO). Basic descriptive statistics were calculated. Results A total of 508 individual patients had 519 admissions, YO 73% (n=379) NO 27% (n=140). There were no significant differences between groups for age, gender, race, ethnicity, admission diagnosis or mortality. Mupirocin was ordered at admission for 379 (73%) and administered per orders 74% of the time. YO patients were more likely to require ICU care 19% (n=73) vs 11% (n=16) (p=0.036) and mechanical ventilation 12% (n=46) vs 4% (n=6) (p=0.008). Length of stay (LOS) was longer for the YO group, 9.9 vs 5.11 days (p=0.008). The majority, 93% (n= 482) were admitted for burn injury, with a mean TBSA of YO 8.37 vs NO 5.86 (p=0.023). For YO, the mean number of doses to be administered, adjusted for LOS, was 6.71 vs actual doses given 3.8 (p &amp;lt; .0001). Overall incidence of MRSA positive blood cultures was 0.6% in the center but when controlled for setting it rose to 3% in ICU admissions. There were no positive blood cultures in non-ICU patients or the NO group. Three YOs had blood cultures positive for MRSA and had 80-90% of doses administered. Days to positive culture from admission were 6, 7 and 15. Conclusions Our review demonstrated that mupirocin was frequently discontinued before a full course was administered, yet the overall incidence of MRSA bacteremia was low, with all cases occurring in the pediatric ICU setting. These findings indicate that our current protocol does not perform well in this population and needs refinement. Universal decolonization in non-ICU pediatric patients is likely unnecessary. Applicability of Research to Practice An evidence-based protocol for children would improve antimicrobial stewardship in a vulnerable population and decrease psychological distress.

Epidemiological profile and risk factors associated with death in patients receiving invasive mechanical ventilation in an adult intensive care unit from Brazil: a retrospective study.

Understanding the epidemiological profile and risk factors associated with invasive mechanical ventilation (IMV) is essential to manage the patients better and to improve health services. Therefore, our objective was to describe the epidemiological profile of adult patients in intensive care that required IMV in-hospital treatment. Also, to evaluate the risks associated with death and the influence of positive end-expiratory pressure (PEEP) and arterial oxygen pressure (PaO2) at admission in the clinical outcome. We conducted an epidemiological study analyzing medical records of inpatients who received IMV from January 2016 to December 2019 prior to the Coronavirus Disease (COVID)-19 pandemic in Brazil. We considered the following characteristics in the statistical analysis: demographic data, diagnostic hypothesis, hospitalization data, and PEEP and PaO2 during IMV. We associated the patients' features with the risk of death using a multivariate binary logistic regression analysis. We adopted an alpha error of 0.05. We analyzed 1,443 medical records; out of those, 570 (39.5%) recorded the patients' deaths. The binary logistic regression was significant in predicting the patients' risk of death [X2(9) = 288.335; p < 0.001]. Among predictors, the most significant in relation to death risk were: age [elderly ≥65 years old; OR = 2.226 (95%CI = 1.728-2.867)]; male sex (OR = 0.754; 95%CI = 0.593-0.959); sepsis diagnosis (OR = 1.961; 95%CI = 1.481-2.595); need for elective surgery (OR = 0.469; 95%CI = 0.362-0.608); the presence of cerebrovascular accident (OR = 2.304; 95%CI = 1.502-3.534); time of hospital care (OR = 0.946; 95%CI = 0.935-0.956); hypoxemia at admission (OR = 1.635; 95%CI = 1.024-2.611), and PEEP >8 cmH2O at admission (OR = 2.153; 95%CI = 1.426-3.250). The death rate of the studied intensive care unit was equivalent to that of other similar units. Regarding risk predictors, several demographic and clinical characteristics were associated with enhanced mortality in intensive care unit patients under mechanical ventilation, such as diabetes mellitus, systemic arterial hypertension, and older age. The PEEP >8 cmH2O at admission was also associated with increased mortality since this value is a marker of initially severe hypoxia.

Dysphagia in adult intensive care patients: Results of a prospective, multicentre binational point prevalence study

BackgroundDysphagia occurs in intensive care unit (ICU) patients. However, there is a lack of epidemiological data on the prevalence of dysphagia in adult ICU patients. ObjectivesThe objective of this study was to describe the prevalence of dysphagia in nonintubated adult patients in the ICU. MethodsA prospective, multicentre, binational, cross-sectional point prevalence study was conducted in 44 adult ICUs in Australia and New Zealand. Data were collected in June 2019 on documentation of dysphagia, oral intake, and ICU guidelines and training. Descriptive statistics were used to report demographic, admission, and swallowing data. Continuous variables are reported as means and standard deviations (SDs). Precisions of estimates were reported as 95% confidence intervals (CIs). ResultsOf the 451 eligible participants, 36 (7.9%) were documented as having dysphagia on the study day. In the dysphagia cohort, the mean age was 60.3 years (SD: 16.37) vs 59.6 years (SD: 17.1) and almost two-thirds were female (61.1% vs 40.1%). The most common admission source for those patients with dysphagia were from the emergency department (14/36, 38.9%), and seven of 36 (19.4%) had a primary diagnosis of trauma (odds ratio: 3.10, 95% CI 1.25 - 7.66). There were no statistical differences in Acute Physiology and Chronic Health Evaluation (APACHE II) scores between those with and without a dysphagia diagnosis. Patients with dysphagia were more likely to have a lower mean body weight of 73.3 kg vs 82.1 kg than patients not documented as having dysphagia (95% CI of mean difference: 0.43 to 17.07) and require respiratory support (odds ratio: 2.12, 95% 1.06 to 4.25). The majority of patients with dysphagia were prescribed modified food and fluids in the ICU. Less than half of ICUs surveyed reported unit-level guidelines, resources, or training for management of dysphagia. ConclusionsThe prevalence of documented dysphagia in adult ICU nonintubated patients was 7.9%. There were a higher proportion of females with dysphagia than previously reported. Approximately two-thirds of patients with dysphagia were prescribed oral intake, and the majority were receiving texture-modified food and fluids. Dysphagia management protocols, resources, and training are lacking across Australian and New Zealand ICUs.

Association Between Preexisting Mental Health Disorders and Adverse Outcomes in Adult Intensive Care Patients: A Data Linkage Study.

Mental illness is known to adversely affect the physical health of patients in primary and acute care settings; however, its impact on critically ill patients is less well studied. This study aimed to determine the prevalence, characteristics, and outcomes of patients admitted to the ICU with a preexisting mental health disorder. A multicenter, retrospective cohort study using linked data from electronic ICU clinical progress notes and the Australia and New Zealand Intensive Care Society Adult Patient Database. All patients admitted to eight Australian adult ICUs in the calendar year 2019. Readmissions within the same hospitalization were excluded. None. Natural language processing techniques were used to classify preexisting mental health disorders in participants based on clinician documentation in electronic ICU clinical progress notes. Sixteen thousand two hundred twenty-eight patients (58% male) were included in the study, of which 5,044 (31.1%) had a documented preexisting mental health disorder. Affective disorders were the most common subtype occurring in 2,633 patients (16.2%), followed by anxiety disorders, occurring in 1,611 patients (9.9%). Mixed-effects regression modeling found patients with a preexisting mental health disorder stayed in ICU 13% longer than other patients (β-coefficient, 0.12; 95% CI, 0.10-0.15) and were more likely to experience invasive ventilation (odds ratio, 1.42; 95% CI, 1.30-1.56). Severity of illness and ICU mortality rates were similar in both groups. Patients with preexisting mental health disorders form a significant subgroup within the ICU. The presence of a preexisting mental health disorder is associated with greater ICU length of stay and higher rates of invasive ventilation, suggesting these patients may have a different clinical trajectory to patients with no mental health history. Further research is needed to better understand the reasons for these adverse outcomes and to develop interventions to better support these patients during and after ICU admission.

Family functioning of families experiencing intensive care and the specific impact of the COVID-19 pandemic: A grounded theory study

ObjectivesIn order to provide a deeper understanding of family functioning, the aim of this study was to identify, describe and conceptualise the family functioning of families where a formerly critically ill family member had stayed at the intensive care unit, with the impact of a pandemic. Research methodology/designThe study has a grounded theory design including interviews with eight families. SettingFormer adult intensive care patients cared for Covid-19 infection and their family. Eight patients and twelve family members from three different intensive care units. Main outcome measuresThe results presented are grounded in data and identified in the core category “Existential issues” and the categories “Value considerateness; Anxiety and insecurity in life; Insight into the unpredictability of life.” FindingsThe core category could be found in all data and its relationship and impact on the categories and each other. The core is a theoretical construction, whereas the family functioning of families where a formerly critically ill family member had stayed at the intensive care unit was identified, described, and conceptualised. Being able to talk repeatedly about existential issues and the anxiety and insecurity in life, with people that have similar experiences helps the patient and their family to consider and gain insight into the unpredictability of life, and thereby better cope with changes in life. ConclusionThere is awareness about the love that exists within the family. A willing to supporting each other in the family even if the critical illness made the family anxious and afraid. Implications for clinical practiceEven if the pandemic Covid-19 led to restrictions inhibiting family focused nursing, it is important to confirm the family as a part of the caring of the ICU patient. The patients are not alone, their family are fighting together for the future.

A knowledge test on pressure injury in adult intensive care patients: Development, validation, and item analysis

BackgroundPressure injuries are a major problem in critically ill patients, but both students' and intensive care nurses’ knowledge about these injuries leaves room for improvement. As no knowledge test is currently available that focuses on pressure injuries in adult intensive care patients, we aimed to develop such tool, establish the content validity, and perform item analysis using Classical test theory. MethodsTest development followed established multiple-choice question-writing guidelines. Content validation used a Delphi procedure including eight international experts. Item analysis (question difficulty and discrimination power, and quality of the distractors) was based on the test results of a convenience sample who completed the test online, based on ready knowledge. ResultsFour Delphi validation rounds resulted in a 24-item multiple-choice test within seven categories: Epidemiology, Aetiology, Prevention, Classification, Risk factors and risk assessment, Wound care, and Skin care. The content validity index was 0.96. The median score of 12 students and 38 qualified nurses was 12.5/24 (interquartile range 11–14.25; range 4–17; 52%). Least correct answers were in the categories Classification and Wound care. Item analysis revealed several knowledge gaps and misconceptions. ConclusionsThe test has excellent content validity. The sample's overall score was low. Item analysis identified various training needs. Future users are recommended to further validate the test and establish its reliability, and to tailor it to their individual context and evaluation requirements.

Sensitivity and specificity of proposed Richards-Campbell Sleep Questionnaire cut-off scores for good quality sleep during an ICU stay.

The 5-visual analogue scale Richards-Campbell Sleep Questionnaire subjective sleep measure is widely used in intensive care. A cut-off score indicative of good quality sleep has not been established and is required to guide the categorisation of individual patient and unit wide sleep quality. The aim was to determine the global Richards-Campbell Sleep Questionnaire cut-off score for good to very good sleep during an intensive care unit stay in non-ventilated patients. The study was a secondary (cohort) retrospective analysis of patient self-report data (n=32) from an interventional study testing a sleep promotion bundle. The Standards for Reporting Diagnostic Accuracy studies statement were used to report the study. The study was conducted in two mixed adult 12 and 20-bed ICUs of a tertiary referral hospital in a metropolitan area. In the morning, eligible patients were administered the Richards-Campbell Sleep Questionnaire together with a 5-category item Likert scale in which patients rated their nocturnal sleep quality as 'very poor', 'poor', 'fair', 'good' and 'very good'. Receiver Operator Curve analysis was performed. Thirty-seven per cent (n=32) of the total sample of 84 adult intensive care patients were females. The median age was 61.5 (51, 72) years. Self-reported median global Richards-Campbell Sleep Questionnaire score was 54.4 (30.1, 77.1) mm. A global score of ≥63.4mm was the optimal cut-off for self-reported 'good sleep' (sensitivity: 87%, specificity: 81% and area under the curve: 0.896). Although the study requires replication in ventilated patients and other ICU settings, the cut-off score (63mm) could be used to guide the categorisation of individual patient and unit wide sleep quality.

Intensive Care Pressure Injuries: A Cohort Study Using the CALCULATE and Braden Scales.

Identify both the risk of developing pressure injuries (PIs) by applying the CALCULATE (CriticAL Care pressure ULcer Assessment Tool made Easy) and Braden Scales and the incidence of PIs in adult patients in intensive care. This prospective cohort study was conducted from March 2016 to February 2017 in an adult ICU. The Braden and CALCULATE scales were applied every 48 hours until medical discharge, death, or PI development. The sample included 100 patients. The investigators obtained 818 evaluations (409 Braden and 409 CALCULATE) with an average of 4.1 observations per patient. According to the CALCULATE scale, 49 participants (49%) were classified as very high risk, compared with 40 participants (40%; P = .204) according to the Braden Scale. Thirty-five patients developed 37 PIs, with a total incidence of 35%. The mean age of patients who developed PIs was 60.3 (SD, 13.7) years, and they averaged 9.2 (SD, 6.8) days of hospitalization, with diagnoses related to cardiorespiratory and neurologic diseases and associated comorbidities of hypertension, diabetes mellitus, and smoking. The most affected site was the sacral region; 64.9% of the injuries were classified as stage 1. Patients in intensive care were high risk according to both PI scales, and many developed PIs. It is evident that even when preventive measures are used, they are insufficient without the implementation of preventive protocols.

Sex Differences in Treatment of Adult Intensive Care Patients: A Systematic Review and Meta-Analysis.

To evaluate and synthesize the available literature on sex differences in the treatment of adult ICU patients. MEDLINE and EMBASE. Two reviewers independently screened publications to identify observational studies of adult ICU patients that explicitly examined the association between sex and ICU treatment-specifically, mechanical ventilation, renal replacement therapy, and length of stay. We extracted data independently and in duplicate: mean age, illness severity, use of mechanical ventilation and renal replacement therapy, and length of stay in ICU and hospital. We assessed risk of bias using the Newcastle-Ottawa Scale. We used a DerSimonian-Laird random-effects model to calculate pooled odds ratios (ORs) and mean differences between women and men. We screened 4,098 publications, identifying 21 eligible studies with 545,538 participants (42.7% women). The study populations ranged from 246 to 261,255 participants (median 4,420). Most studies (76.2%) were at high risk of bias in at least one domain, most commonly representativeness or comparability. Women were less likely than men to receive invasive mechanical ventilation (OR, 0.83; 95% CI, 0.77-0.89; I2 = 90.4%) or renal replacement therapy (OR, 0.79; 95% CI, 0.70-0.90; I2 = 76.2%). ICU length of stay was shorter in women than men (mean difference, -0.24 d; 95% CI, -0.37 to -0.12; I2 = 89.9%). These findings persisted in meta-analysis of data adjusted for illness severity and other confounders and also in sensitivity analysis excluding studies at high risk of bias. There was no significant sex difference in duration of mechanical ventilation or hospital length of stay. Women were less likely than men to receive mechanical ventilation or renal replacement therapy and had shorter ICU length of stay than men. There is substantial heterogeneity and risk of bias in the literature; however, these findings persisted in sensitivity analyses.

Long-term stability of ready-to-use epinephrine 0.02 mg/mL injection solution in 50 mL glass vials

Abstract Objectives In adult intensive care patients, epinephrine is mostly administered by continuous injection with syringe pumps. The objective of this study was to investigate the physicochemical stability of pharmacy prepared ready-to-use epinephrine (E) 0.02 mg/mL injection solutions (total volume 50 mL) for assigning shelf-life. Methods E 0.02 mg/mL injection solution in 50 mL amber type l glass vials was produced batch-wise in the pharmacy department. Stability of the refrigerated (2–8 °C) product was investigated in real time over a period of 36 months by analyzing E concentrations, osmolality, pH, and sub-visible particles at predefined time-points. For E concentration measurements a stability-indicating, validated reversed-phase HPLC-PDA assay was used. Results The autoclaving process of E 0.02 mg/mL injection solution in 50 mL amber type I glass vials caused 5% loss of the active substance. The finished product remained stable over the study period of 36 months when stored refrigerated. Conclusions Batch-wise production of ready-to-use E injection solution 0.02 mg/mL in 50 mL amber glass vials was successfully implemented in our pharmacy department. According to the stability tests, a shelf-life of 36 months can be assigned to the finished product stored refrigerated. Studies concerning stability at room temperature would be useful.

The Pharmacokinetics of Levetiracetam in Critically Ill Adult Patients: An Intensive Care Unit Clinical Study

The aim of this study was to investigate levetiracetam pharmacokinetics in critically ill adult intensive care patients and to identify pathophysiological factors affecting its kinetics. Fourteen critically ill patients in an intensive care unit were enrolled in the study and received intravenous levetiracetam. Blood samples were collected at specific time points to determine the levetiracetam pharmacokinetics. Patient characteristics such as renal function, demographics, disease severity, organ dysfunction, and biochemical laboratory tests were evaluated for their influence on the kinetics of levetiracetam. Estimated glomerular filtration rate (eGFR) had a statistically significant (p = 0.001) effect on levetiracetam clearance. None of the other patient characteristics had a statistically significant effect on the pharmacokinetics. Simulations of dosing regimens revealed that even typically administered doses of levetiracetam may result in significantly increased concentrations and risk of drug toxicity in patients with impaired renal function. The Acute Physiology and Chronic Health Evaluation II (APACHE II) score differed significantly among the three groups with different epileptic activity (p = 0.034). The same groups also differed in terms of renal function (p = 0.031). Renal dysfunction should be considered when designing levetiracetam dosage. Patients with a low APACHE II score had the lowest risk of experiencing epileptic seizures.
