Correlation analysis between lung ultrasound scores and pulmonary arterial systolic pressure in patients with acute heart failure admitted to the emergency intensive care unit

BackgroundNo convenient, inexpensive, and non-invasive screening tools exist to identify pulmonary hypertension (PH) - left heart disease (LHD) patients during the early stages of the disease course. This study investigated whether different methods of lung ultrasound (LUS) could be used for the initial investigation of PH-LHD. MethodsThis was a single-center prospective observational study which was performed in the Zigong Fourth People's Hospital. We consecutively enrolled patients with heart failure (HF) admitted to the emergency intensive care unit from January 2018 to May 2020. Transthoracic echocardiography and LUS were performed within 24 h before discharge. We used the Spearman coefficient for correlation analysis between ultrasound scores and pulmonary arterial systolic pressure (PASP). Bland-Altman plots were generated to inspect possible bias, and receiver operating characteristic (ROC) curves were calculated to assess the relationship between ultrasound scores and an intermediate and high echocardiographic probability of PH-LHD. ResultsSeventy-one patients were enrolled in this study, with an overall median age of 79 (interquartile range: 71.5–84.0) years. Among the 71 patients, 36 (50.7%) cases were male, and 26 (36.6%) had an intermediate and high echocardiographic probability of PH. All four LUS scores in patients with an intermediate and high probability of PH were significantly higher than in patients with a low probability of PH (P <0.05). The correlation coefficient (r) between different LUS scoring methods and PASP was moderate for the 6-zone (r=0.455, P <0.001), 8-zone (r=0.385, P=0.001), 12-zone (r=0.587, P <0.001), and 28-zone (r=0.535, P <0.001) methods. In Bland-Altman plots, each of the four LUS scoring methods had a good agreement with PASP (P <0.001). The 8-zone and 12-zone methods showed moderately accurate discriminative values in differentiating patients with an intermediate and high echocardiographic probability of PH (P <0.05). ConclusionsLUS is a readily available, inexpensive, and risk-free method that moderately correlates with PASP. LUS is a potential screening tool used for the initial investigation of PH-LHD, especially in emergencies or critical care settings.

Pathophysiology and management of heat illness

The frequency and intensity of heat waves are currently increasing due to climate change. Hence more cases of heat illness are being observed, apotentially life-threatening disease, which requires rapid and expert management. An overview of the pathophysiology and acute management of heat illness is presented. Analysis and evaluation of important, recently published contributions, studies, and reviews regarding heat illness without claim for completeness or fulfilling the criteria for a'systematic meta-analysis'. Presentation of arecommended clinical-practical classification and management of heat illness in emergency departments or intensive care units. The manifestation of heat illness arising from prolonged exposure to heat prevaries (heat cramps, heat edema, heat exhaustion, heat stroke). The main pathophysiologic mechanisms are disruption of thermoregulation, peripheral vasodilation of the skin surface, hypoperfusion of visceral organs, and brain, and cardiac stress. Uncompensated heat stress can result in multiorgan dysfunction/failure syndrome due to the initiation of cytokine pathways, specifically in at-risk and/or chronically ill patients. The manifestation of uncompensated heat stroke is associated with ahospital mortality > 50%. Rapid identification, classification and targeted management are crucial for the outcome, in particular the initiation of adequate cooling measures. In the future, increasing numbers of patients suffering from prolonged heat exposure will require treatment in emergency departments and intensive care units. Sufficient professional knowledge regarding pathophysiology and management are decisive for successful therapy. Hence, the topic heat illness should be implemented in training and education.

Preparation/administration of push-dose versus continuous infusion epinephrine and phenylephrine: A simulation

BackgroundHypotension is a common problem in the emergency department (ED) and intensive care unit (ICU) and can increase risk for poor outcomes. Many EDs/ICUs utilize epinephrine and phenylephrine to treat hypotension and these medications are most often administered as a continuous infusion (CI). Push-dose (PD) is the administration of small medication doses as intermittent intravenous pushes (IVPs). There is limited information comparing the time required to prepare and administer PD versus CI and errors have been reported when preparing and administering these medications at bedside. This simulation study sought to estimate preparation and administration times and preparation and errors with PD and CI epinephrine and phenylephrine when prepared by an ED/ICU pharmacist. MethodsThis crossover simulation study took place in a simulation center at an academic medical center and utilized a multi-venous intravenous training arm kit equip with an 18-gauge intravenous line, an extension tubing set, and a luer-lock adapter. The primary outcome was total preparation and administration time in seconds. The secondary outcome was major preparation and administration errors, defined as errors causing a five-fold or greater overdose. ResultsIn total, 16 pharmacists participated, including nine ED and seven ICU pharmacists. PD had faster total preparation and administration time and administration time, but not preparation time; PD showed an approximate 70 s decrease in total preparation and administration time versus CI. PD had more major preparation and administration errors and six PD preparations (18.8%, 6/32) had at least one major preparation and administration error. CI, on the other hand, had no major preparation and administration errors. DiscussionThis simulation found faster total preparation and administration time with PD versus CI epinephrine and phenylephrine, but also found that PD had more major preparation and administration errors. Dilutional errors during medication preparation were the cause of 83.3% (5/6) of our overdoses. ConclusionThis simulation study showed that ED/ICU pharmacists had faster median total preparation and administration times for PD epinephrine and phenylephrine versus CI, but PD also had more preparation and administration errors.

Effect of improved nursing strategy on prognosis of older immunosuppressed patients with pneumonia and sepsis

To investigate the effect of improved nursing strategy on prognosis of older immunosuppressed patients with pneumonia and sepsis. A prospective study was conducted. The older immunosuppressed patients with pneumonia and sepsis admitted to the department of intensive care medicine and emergency intensive care unit (ICU) of Peking Union Medical College Hospital from January 2017 to July 2022 were enrolled. In the first stage (from January 2017 to December 2019), patients received the original nursing strategy (original nursing strategy group), including: (1) nurses were randomly assigned; (2) routine terminal cleaning; (3) ICU environmental cleaning twice a day; (4) oral care was performed with chlorhexidine twice a day; (5) original lung physiotherapy [head of bed elevated at 30 degree angle-45 degree angle, maintaining a Richmond agitation-sedation scale (RASS) -2 to 1, sputum aspiration as needed]. After 1 month of learning and training of the modified nursing treatment strategy for nurses and related medical staff, the patients in the second stage (from February 2020 to July 2022) received the improved nursing strategy (improved nursing strategy group). The improved nursing strategy improved the hospital infection prevention and control strategy and lung physical therapy strategy on the basis of the original nursing strategy, including: (1) nurses were fixed assigned; (2) patients were placed in a private room; (3) enhanced terminal cleaning; (4) ICU environmental cleaning four times a day; (5) education and training in hand hygiene among health care workers was improved; (6) bathing with 2% chlorhexidinegluconate was performed once daily; (7) oral care with a combination of chlorhexidine and colistin was provided every 6 hours; (8) surveillance of colonization was conducted; (9) improved lung physiotherapy (on the basis of the original lung physiotherapy, delirium score was assessed to guide early mobilization of the patients; airway drainage was enhanced, the degree of airway humidification was adjusted according to the sputum properties, achieving sputum viscosity grade II; lung ultrasound was also used for lung assessment, and patients with atelectasis were placed in high lateral position and received the lung recruitment maneuver). Baseline patient information were collected, including gender, age, underlying diseases, source of admission, disease severity scores, vital signs, ventilatory parameters, blood gas analysis, life-sustaining treatments, clinical laboratory evaluation, indicators of infection and inflammation, pathogens and drug therapy. The primary outcome was 28-day mortality, and the secondary outcomes were duration of mechanical ventilation, length of ICU stay, and ICU mortality. Multivariate Logistic regression analysis was used to determine the risk factors for 28-day death in older immunosuppressed patients with pneumonia and sepsis. Finally, 550 patients were enrolled, including 199 patients in the original nursing strategy group and 351 patients in the improved nursing strategy group. No significant differences were found in gender, age, underlying diseases, source of admission, disease severity scores, vital signs, ventilatory parameters, blood gas analysis, life-sustaining treatments, clinical laboratory evaluation, indicators of infection and inflammation, coexisting pathogens or drug therapy between the two groups. Compared with patients in the original nursing strategy group, those in the improved nursing strategy group had significantly fewer duration of mechanical ventilation and length of ICU stay [duration of mechanical ventilation (days): 5 (4, 7) vs. 5 (4, 9), length of ICU stay (days): 11 (6, 17) vs. 12 (6, 23), both P < 0.01], and lower ICU mortality and 28-day mortality [ICU mortality: 23.9% (84/351) vs. 32.7% (65/199), 28-day mortality: 23.1% (81/351) vs. 33.7% (67/199), both P < 0.05]. Multivariate Logistic regression analysis showed that the improved nursing strategy acted as an independent protective factor in 28-day death of older immunosuppressed patients with pneumonia and sepsis [odds ratio (OR) = 0.543, 95% confidence interval (95%CI) was 0.334-0.885, P = 0.014]. Improved nursing strategy shortened the duration of mechanical ventilation and the length of ICU stay, and decreased ICU mortality and 28-day mortality in older immunosuppressed patients with pneumonia and sepsis, significantly improving the short-term prognosis of such patients.

Deep Learning for Automated Triaging of Stable Chest Radiographs in a Follow-up Setting.

Background Most artificial intelligence algorithms that interpret chest radiographs are restricted to an image from a single time point. However, in clinical practice, multiple radiographs are used for longitudinal follow-up, especially in intensive care units (ICUs). Purpose To develop and validate a deep learning algorithm using thoracic cage registration and subtraction to triage pairs of chest radiographs showing no change by using longitudinal follow-up data. Materials and Methods A deep learning algorithm was retrospectively developed using baseline and follow-up chest radiographs in adults from January 2011 to December 2018 at a tertiary referral hospital. Two thoracic radiologists reviewed randomly selected pairs of "change" and "no change" images to establish the ground truth, including normal or abnormal status. Algorithm performance was evaluated using area under the receiver operating characteristic curve (AUC) analysis in a validation set and temporally separated internal test sets (January 2019 to August 2021) from the emergency department (ED) and ICU. Threshold calibration for the test sets was conducted, and performance with 40% and 60% triage thresholds was assessed. Results This study included 3 304 996 chest radiographs in 329 036 patients (mean age, 59 years ± 14 [SD]; 170 433 male patients). The training set included 550 779 pairs of radiographs. The validation set included 1620 pairs (810 no change, 810 change). The test sets included 533 pairs (ED; 265 no change, 268 change) and 600 pairs (ICU; 310 no change, 290 change). The algorithm had AUCs of 0.77 (validation), 0.80 (ED), and 0.80 (ICU). With a 40% triage threshold, specificity was 88.4% (237 of 268 pairs) and 90.0% (261 of 290 pairs) in the ED and ICU, respectively. With a 60% triage threshold, specificity was 79.9% (214 of 268 pairs) and 79.3% (230 of 290 pairs) in the ED and ICU, respectively. For urgent findings (consolidation, pleural effusion, pneumothorax), specificity was 78.6%-100% (ED) and 85.5%-93.9% (ICU) with a 40% triage threshold. Conclusion The deep learning algorithm could triage pairs of chest radiographs showing no change while detecting urgent interval changes during longitudinal follow-up. © RSNA, 2023 Supplemental material is available for this article.

Trends and Outcomes of Early Rehabilitation in the Intensive Care Unit for Patients With Cardiovascular Disease: A Cohort Study With Propensity Score-Matched Analysis.

The effectiveness of acute-phase cardiovascular rehabilitation (CR) in intensive care settings remains unclear in patients with cardiovascular disease (CVD). This study aimed to investigate the trends and outcomes of acute-phase CR in the intensive care unit (ICU) for patients with CVD, including in-hospital and long-term clinical outcomes. This retrospective cohort study reviewed a total of 1,948 consecutive patients who were admitted to a tertiary academic ICU for CVD treatment and underwent CR during hospitalisation. The endpoints of this study were the following: in-hospital outcomes: probabilities of walking independence and returning home; and long-term outcomes: clinical events 5 years following hospital discharge, including all-cause readmission or cardiovascular events. It evaluated the associations of CR implementation during ICU treatment (ICU-CR) with in-hospital and long-term outcomes using propensity score-matched analysis. Among the participants, 1,092 received ICU-CR, the rate of which tended to increase with year trend (p for trend <0.001). After propensity score matching, 758 patients were included for analysis (pairs of n=379 ICU-CR and non-ICU-CR). ICU-CR was significantly associated with higher probabilities of walking independence (rate ratio, 2.04; 95% CI 1.77-2.36) and returning home (rate ratio, 1.22; 95% CI 1.05-1.41). These associations were consistently observed in subgroups aged >65 years, after surgery, emergency, and prolonged ICU stay. ICU-CR showed significantly lower incidences of all-cause (HR 0.71; 95% CI 0.56-0.89) and cardiovascular events (HR 0.69; 95% CI 0.50-0.95) than non-ICU-CR. The implementation of acute-phase CR in ICU increased with year trend, and is considered beneficial to improving in-hospital and long-term outcomes in patients with CVD and various subgroups.

Current role of portable MRI in diagnosis of acute neurological conditions.

Neuroimaging is an inevitable component of the assessment of neurological emergencies. Magnetic resonance imaging (MRI) is the preferred imaging modality for detecting neurological pathologies and provides higher sensitivity than other modalities. However, difficulties such as intra-hospital transport, long exam times, and availability in strict access-controlled suites limit its utility in emergency departments and intensive care units (ICUs). The evolution of novel imaging technologies over the past decades has led to the development of portable MRI (pMRI) machines that can be deployed at point-of-care. This article reviews pMRI technologies and their clinical implications in acute neurological conditions. Benefits of pMRI include timely and accurate detection of major acute neurological pathologies such as stroke and intracranial hemorrhage. Additionally, pMRI can be potentially used to monitor the progression of neurological complications by facilitating serial measurements at the bedside.

5-Years of Thrombolytic Treatment Experience

Objective: Thrombolytic therapy has a vital role in saving both life and vital functions in emergency room patients. Our aim in our study is to reveal the thrombolytic practice experience of a 3rd level hospital in a long period of 5 years.&#x0D; Methods: Adult patients who applied to the emergency department between 2017-2022 and were given thrombolytic therapy were selected. Demographic information, risk factors, laboratory and radiological parameters, diagnoses and thrombolytic use of the patients were examined.&#x0D; Results: 56 patients were included in the study. Survival in patients with comorbidity was lower than in patients without comorbidity (p=0.0036). Survival of patients with a history of cerebrovascular occlusion was lower than those without (p=0.01). There was no statistically significant difference in survival between patients who received coagulation therapy in their history and patients (p&gt;0.05). Survival analysis was performed according to the diagnosis of the patients in the emergency department. There was no statistical significance in terms of survival among patients with different diagnosis types (p=0.098). No statistically significant difference was found in the survival analysis for different application sites of thrombolytic therapy as emergency room, clinical service and intensive care unit (p=0.85). It was observed that doctors started thrombolytic practice as of 2017, and the number of applications increased over the years.&#x0D; Conclusion: The favorable outcomes thrombolytic therapy have led an increase in the number of thrombolytic therapy conducted by ED clinicians while it was also seen that there was a reduction in morbidity and mortality over time.

In vivo gene expression profile of Haemophilus influenzae during human pneumonia.

Haemophilus influenzae is a major cause of community-acquired pneumonia. While studied extensively in various laboratory models, less is known about the cell function while inside the human lung. We present the first analysis of the global gene expression of H. influenzae while the bacteria are in the lung during pneumonia (in vivo conditions) and contrast it with bacterial isolates that have been cultured under standard laboratory conditions (in vitro conditions). Patients with pneumonia were recruited from emergency departments and intensive care units during 2018-2020 (n = 102). Lower respiratory samples were collected for bacterial culture and RNA extraction. Patient samples with H. influenzae (n = 8) and colonies from bacterial cultures (n = 6) underwent RNA sequencing. The reads were then pseudo-aligned to core and pan genomes created from 15 reference strains. While bacteria cultured in vitro clustered tightly by principal component analysis of core genome (n = 1067) gene expression, bacteria in the patient samples had more diverse transcriptomic signatures and did not group with their lab-cultured counterparts. In total, 328 core genes were significantly differentially expressed between in vitro and in vivo conditions. The most highly upregulated genes in vivo included tbpA and fbpA, which are involved in the acquisition of iron from transferrin, and the stress response gene msrAB. The biosynthesis of nucleotides/purines and molybdopterin-scavenging processes were also significantly enriched in vivo. In contrast, major metabolic pathways and iron-sequestering genes were downregulated under this condition. In conclusion, extensive transcriptomic differences were found between bacteria while in the human lung and bacteria that were cultured in vitro. IMPORTANCE The human-specific pathogen Haemophilus influenzae is generally not well suited for studying in animal models, and most laboratory models are unlikely to approximate the diverse environments encountered by bacteria in the human airways accurately. Thus, we have examined the global gene expression of H. influenzae during pneumonia. Extensive differences in the global gene expression profiles were found in H. influenzae while in the human lung compared to bacteria that were grown in the laboratory. In contrast, the gene expression profiles of isolates collected from different patients were found to cluster together when grown under the same laboratory conditions. Interesting observations were made of how H. influenzae acquires and uses iron and molybdate, endures oxidative stress, and regulates central metabolism while in the lung. Our results indicate important processes during infection and can guide future research on genes and pathways that are relevant in the pathogenesis of H. influenzae pneumonia.

148 Urinary incontinence: a hospital inpatient point prevalence study

Abstract Background Urinary incontinence is a common, although under-reported, problem in hospitalised older adults. One Irish study reported that 26% of hospitalised patients had urinary incontinence. Hospital-acquired urinary incontinence is associated with prolonged hospital stays, infection, poorer functional outcome, and poorer quality of life. We undertook a point prevalence study of all inpatients in a Level 3 hospital, as part of an audit focused on documentation and awareness of urinary incontinence. Methods Data were gathered on all inpatient at a single timepoint. The Emergency Department and Intensive Care Unit were excluded. Biographical data, admission diagnoses, diagnosis of dementia, delirium and urinary incontinence, use of diuretics and urinary incontinence medications, toileting plans, continence care bundles and mobility status were gathered from medical notes, nursing notes and drug Kardexes. Results The dataset compromised 309 patients. 11% were &amp;lt; 50 years old, 8% aged 50–59, 15% aged 60–69, 29% aged 70–79, 29% aged 80–89 and 8% were &amp;gt; 90 years old. 24% had a diagnosis of dementia, and 25% had delirium. Pre-admission continence status was known for 81% of patients; 8% catheterised, 12% incontinent, 12% had occasional accidents and 68% of patients were continent. At the time of data collection, 21% were catheterised. 14% incontinent, 18% had occasional accidents and 48% of patients were continent. 10% of patients were prescribed medications for urinary incontinence and 22% diuretics. 12% of patients with dementia were continent and 18% of patients with delirium. 40% of patients were independently mobile, 32% required assistance of one person, 17% assistance of two and 11% required a hoist. Dependent mobility was associated with increased rates of incontinence. Conclusion Our study found a high prevalence of urinary incontinence in hospitalised patients. Risk factors identified included older age, reduced mobility, long duration of admission, presence of dementia and or delirium and use of diuretics. These risk factors could be targeted as quality improvement initiative to promote continence in hospitalised patients,

Nighttime working as perceived by Italian anesthesiologists: a secondary analysis of an international survey

BackgroundNo data are available on the working conditions and workload of anesthesiologists during perioperative nighttime work in Italy and on the perceived risks.ResultsWe analyzed 1085 responses out of the 5292 from the whole dataset. Most of the responders (76%) declared working a median of 12 consecutive hours during night shifts, with an irregular nightshift schedule (70%). More than half of the responders stated to receive a call 2–4 (40%) or 5 times or more (25%) to perform emergency procedures and/or ICU activities during night shifts. More than 70% of the responders declared having relaxation rooms for nighttime work (74%) but none to be used after a nightshift before going back home (82%) and no free meals, snacks, or beverages (89%). Furthermore, almost all (95%) of the surveyed anesthesiologists declared not having received specifical training or education on how to work at night, and that no institutional program has been held by the hospital to monitor fatigue or stress for night workers (99%). More than half of the responders stated having the possibility, sometimes (38%) or always (45%), to involve another colleague in difficult medical decisions and to feel comfortable, sometimes (31%) or always (35%), to call the on-call colleague. Participants declared that nighttime work affects their quality of life extremely (14%) or significantly (63%), and that sleep deprivation, fatigue, and current working conditions may reduce performance (67%) and increase risk for the patients (74%).ConclusionsItalian anesthesiologists declare current nighttime practice to negatively affect their quality of life, and their performance, and are thus concerned for their patients’ safety. Proper education on night work, starting from traineeship, and implementing institutional programs to monitor stress and fatigue of operators and to support them during nighttime work could be a mean to improve nighttime work conditions and safety for both patients and healthcare workers.

Creating blood conservation for a cardiothoracic surgical hospital: when you have to start from scratch!

This improvement report presents a hospital blood-management programme, a hospital-specific model that differs from patient blood managment and was aimed at improving operational standards of transfusion. We identified the challenges of the transfusion process and suggest practical strategies for improving them. The aim of this article was to investigate the effect of the programme on the transfusion of blood components. In January 2019, the programme was started to improve the transfusion process. The data before and after the start of the programme were compared. Frequency distribution was obtained for each variable for statistical analysis and the chi-squared test with continuity correction was used to compare these variables for the years 2018 and 2019. Transfusion of total blood components decreased by 23.2%, fresh whole blood by 46.7%, fresh frozen plasma by 38.4%, pooled platelets by 14.0% and red blood cells by 9.66%. Autologous transfusion increased 11.7-fold. The emergency department (76.0%) and intensive care unit transfusion rate (9.26%) decreased significantly. This programme is an example for hospitals where patient blood management cannot be applied. The programme can be considered the first step for blood management and may be applied to blood management in institutions worldwide. The difficulty of blood supply and increased cost will increase the importance of hospital blood-management programmes in the coming years.

Factors associated with mental health outcomes after COVID-19: A 24-month follow-up longitudinal study

ObjectiveInvestigate the proportion of mental health outcomes (MHOs) and associated factors in COVID-19 survivors during a 24-month follow-up period. MethodAn observational, prospective study was performed in a teaching hospital in Barranquilla, Colombia, from April 1, 2020, to August 30, 2022. A cohort of 1565 COVID-19 survivors was recruited after discharge from the emergency room (ER), inpatient floor (IF), and intensive care unit (ICU) services and followed for 24 -months. The clinical assessment included screening scales for symptoms of anxiety, depressive, post-traumatic stress disorder (PTSD), and insomnia. Sociodemographic and clinical factors were also collected to identify possible associated factors. Descriptive, bivariate and mixed random-effect linear models were performed. ResultsA total of 1565 patients were included, of whom 785 (50.35%) were men. A large proportion of patients with mental symptoms were identified. After 24-months, the proportions of anxiety, depression, PTSD, and insomnia symptoms remained high at 16.55%, 21.79%, 35.27%, and 23.86%, respectively. Social factors, location of hospital stays, physical comorbidities, and the severity of COVID-19 were significantly associated with anxiety, depression, PTSD, and insomnia symptoms. ConclusionsCOVID-19's 2-year deleterious impacts on mental health, as well as the variables influencing these findings, have been documented. These results should aid in the development of public health initiatives to reduce morbidity rates in post-COVID-19 patients.

Improving Situational Awareness to Decrease Emergency ICU Transfers for Hospitalized Pediatric Cardiology Patients.

Failure to recognize and mitigate critical patient deterioration remains a source of serious preventable harm to hospitalized pediatric cardiac patients. Emergency transfers (ETs) occur 10-20 times more often than code events outside the intensive care unit (ICU) and are associated with morbidity and mortality. This quality improvement project aimed to increase days between ETs and code events on an acute care cardiology unit (ACCU) from a baseline median of 17 and 32 days to ≥70 and 90 days within 12 months. Institutional leaders, cardiology-trained physicians and nurses, and trainees convened, utilizing the Institution for Healthcare Improvement model to achieve the project aims. Interventions implemented focused on improving situational awareness (SA), including a "Must Call List," evening rounds, a visual management board, and daily huddles. Outcome measures included calendar days between ETs and code events in the ACCU. Process measures tracked the utilization of interventions, and cardiac ICU length of stay was a balancing measure. Statistical process control chart methodology was utilized to analyze the impact of interventions. Within the study period, we observed a centerline shift in primary outcome measures with an increase from 17 to 56 days between ETs and 32 to 62 days between code events in the ACCU, with sustained improvement. Intervention utilization ranged from 87% to 100%, and there was no observed special cause variation in our balancing measure. Interventions focused on improving SA in a particularly vulnerable patient population led to sustained improvement with reduced ETs and code events outside the ICU.

Knowledge of pulse oximetry among emergency and critical care nurses.

The pulse oximeter is a simple, cost-effective and reliable device for estimating arterial blood oxygen saturation. Nurses are required to be knowledgeable in pulse oximeter use. Little is known about nurses' knowledge of pulse oximetry in the Middle East region. To assess nurses' knowledge of pulse oximetry among emergency and critical care nurses and to explore predictors of nurses' knowledge of pulse oximetry. This is the second part of data analysis that was first presented in the 'proficiency in ECG' study conducted in Jordan. The original data used for both parts of analysis included a questionnaire with two tests; a knowledge of pulse oximeter test and an ECG proficiency test. Participants were asked to take, alone without receiving assistance, both tests. In this study, the second part of analysis, the focus is on the pulse oximeter test. The test consisted of 21 items that emphasize knowledge of basic physiological principles as well as device limitations; whether technical or interpretation. The test administration procedure also included asking participants to provide socio-demographic variables. In the original data collected in both parts of analysis, nurses working in the emergency department, cardiac care units or intensive care units from nine different hospitals (1 governmental, 6 private and 2 educational) and holding a bachelor degree or higher were asked to participate. The total number of participating nurses was 210; out of 247 approached (response rate, 85%). The mean score in the nurses' knowledge of pulse oximetry test was 12.33 out of 21, corresponding to 58.7%. The clinical area currently working in predicted the knowledge of pulse oximetry test score after controlling for all other variables. Emergency department and intensive care unit nurses scored higher than cardiac care unit nurses by 1.86 and 1.63 points respectively (58.2% and 60% respectively). Nurses consistently report inadequate education and training concerning pulse oximeter use and interpretation. A revision to hospital in-service education seminars and undergraduate nurses' curriculum to assure adequate preparation is needed. Knowledge of pulse oximetry among emergency and critical care nurses is modest. This is a challenge worldwide. Predictors of nurses' knowledge of pulse oximetery are the clinical area currently working in (ICU and ED nurses are more knowledgeable than CCU nurses), proficiency in electrocardiography and taking an advanced cardiac life support course.

High dose esomeprazole as an anti-inflammatory agent in sepsis: Protocol for a randomized controlled trial

BackgroundSepsis is caused by dysregulated immune responses due to infection and still presents high mortality rate and limited efficacious therapies, apart from antibiotics. Recent evidence suggests that very high dose proton pump inhibitors might regulate major sepsis mediators' secretion by monocytes, which might attenuate excessive host reactions and improve clinical outcomes. This effect is obtained with doses which are approximately 50 times higher than prophylactic esomeprazole single daily administration and 17 times higher than the cumulative dose of a three day prophylaxis. We aim to perform a randomized trial to investigate if high dose esomeprazole reduces organ dysfunction in patients with sepsis or septic shock. MethodsThis study, called PPI-SEPSIS, is a multicenter, randomized, double blind, placebo-controlled clinical trial on critically ill septic patients admitted to the emergency department or intensive care unit. A total of 300 patients will be randomized to receive high dose esomeprazole (80 mg bolus followed by 12 mg/h for 72 h and a second 80 mg bolus 12 h after the first one) or equivolume placebo (sodium chloride 0.9%), with 1:1 allocation. The primary endpoint of the study will be mean daily Sequential Organ Failure Assessment (SOFA) score over 10 days. Secondary outcomes will include antibiotic-free days, single organ failure severity, intensive care unit-free days at day 28, and mortality. DiscussionThis trial aims to test the efficacy of high dose esomeprazole to reduce acute organ dysfunction in patients with septic shock.Trial registration: This trial was registered on ClinicalTrials.gov with the trial identification NCT03452865 in March 2018.

A total of 25 health workers participated in this activity. The mean pre and post test were 34,38% and 68,42% (an increase of 34%). Participants' satisfaction with the activity was good, namely 4.13 (from a Likert scale of 0 – 5). The aspect of material provided in this training had the highest satisfaction score. This education should be given periodically to all health workers to increase the capacity of stroke services.

Lupus eritematoso sistémico en la unidad de cuidados intensivos de urgencias

ObjectivesTo compare the characteristics of patients who died versus those who survived with systemic lupus erythematosus (SLE) in the emergency intensive care unit (UCIE). Material and methodsRetrospective collection of clinical and laboratory findings of clinical histories of patients with SLE in the UCIE of the Hospital Clínico Quirúrgico de Holguín in the period from January 2016 to January 2021. A descriptive statistical study and univariate analysis were carried out for continuous and discrete variables. The APACHE II score was calculated. ResultsThere were 23 patients with SLE during the period worked. The frequency of SLE in the ICU of the Hospital Clínico Quirúrgico de Holguín is 1.5%, it is the most frequent rheumatic pathology in ICU. Mortality in the ICU was 39.13%. The most frequent reason for admission was respiratory failure (52.4%), mostly due to an infectious cause. The variables that were significantly associated with mortality in the UCIE were: high erythrocyte sedimentation rate (ESR), severe anemia, severe hypoalbuminemia, the relationship arterial oxygen pressure between the fraction of inspired oxygen (PaFi)<200 on admission. The APACHE II score in the deceased group was significantly higher (19.9) (P<.01). Acute renal failure requiring hemodialysis and the need for invasive mechanical ventilation in different modalities for variable times were significantly associated with higher mortality in ICU. ConclusionsSLE in the ICU of the Hospital Clínico Quirúrgico de Holguín has a high mortality rate, higher than that reported in previous studies. Poor prognostic factors were high ESR, severe anemia, severe hypoalbuminemia, PaFi<200, high APACHE II score, need for hemodialysis and invasive mechanical ventilation.

Profile of Splash, Sharp and Needle-Stick Injuries Among Healthcare Workers in a Tertiary Care Hospital in Southern India.

Background and objective Among biological hazards faced by healthcare workers, one of the most commonly reported is sharp-related injury. Needle-stick and sharp injuries transmit infectious diseases, especially blood-borne viruses. The conditions in which these exposures occur vary. Reporting of exposure and proper post-exposureprophylactic measures are important in controlling blood-borne infections in healthcare workers. Better analysis ofsuchaccidents is an important toolto reinforce exposure preventive measures. Hence, we conducted a study to describe the profile of splash, sharp and needle-stick injuries among healthcare workers in a tertiary care hospital. Methods A record-based cross-sectional study was done in a tertiary care hospital, in south Tamil Nadu. All healthcare workers who have reported needle stick, sharp, or splash injuries during the last five years in the hospital were included. Data was extracted from post-exposure reports maintained in the hospital. Results are expressed in mean, standard deviation and percentages. Results A total of 189 healthcare workers (HCWs) had reported instances of splash, sharp and needle stick injuries in the last five years. The most common exposure was needle prick (86.2%), followed by splash of fluids (7.4%). The majority of HCWs were from the nursing department (44.4%), and the most commonly reported place of exposure was the Emergency Department and Intensive Care Unit (ICU) (30.3%), followed by inpatient wards. The associated activity in the majority of the injuries/exposures was the transfer of sharps or cleaning surfaces (26.4%), followed by blood withdrawal (25.7%). After the exposure, 99.5% of HCWs washed the wound immediately. In a total of 135 exposures, the identity of the source, and thus, the serological status was known. Among these, hepatitis B was the most common (17.8%), followed by HIV (11.9%). All exposures related to unknown sources were considered positive exposure and were managed accordingly. Among the HCWs with possible seropositive exposure to hepatitis B, antibody titres were recorded and HBV Immunoglobulin (low titre), and vaccination were administered accordingly. Among the possible HIV exposures, 97.1% of HCWs initiated post-exposure prophylaxis (PEP). All probable hepatitis C exposures were given counseling and advised to follow up. No seroconversion at six months of follow-up has been recorded till now. Conclusion Healthcare workers are constantly at risk of exposure to splash, sharp and needle stick injuries, and although all categories of workers are at risk, nurses are at particularly high risk. A variety of activities can result in injury or a splash of fluids and so preventive activities, including health education, should be focused on all areas of healthcare and for all healthcare workers. More awareness is needed among healthcare workers regarding post-exposure prophylaxis.
