Is increased Mean platelet volume associated with neurologic outcome after non-traumatic subarachnoid hemorrhage?

Objective@#This study evaluated the clinical usefulness of mean platelet volume (MPV) for predicting functional outcomes in subarachnoid hemorrhage (SAH) patients. @*Methods@#This is a retrospective analysis of patients who were diagnosed with SAH in the emergency room. Based on their modified Rankin Scale (mRS) score, patients were divided into two groups: 0-2 (good outcome) and 3-6 (poor outcome). Univariable and multivariable analyses were performed to investigate whether MPV, along with other multiple factors, was associated with poor prognosis. Receiver operating characteristic (ROC) curve analysis was performed to determine the value of MPV as a predicting factor of neurological prognosis. Compared to other factors, Hunt Hess grade (HHG) and modified Fisher grade (mFG) considerably influenced the outcomes in both groups (Model 1; model including all factors). Hence, a new model (Model 2) was constructed, comprising multiple factors excluding these two factors. @*Results@#A total of 143 patients were included in this study. Although MPV was different between the two groups, it was not a significant factor in Model 1 in the multivariable analysis. In Model 2, MPV (odds ration [OR], 1.71; 95% confidence interval [CI], 1.05-2.8), age (OR, 1.06; 95% CI, 1.03-1.1), and surgical treatment (OR, 0.37; 95% CI, 0.15-0.87) were significant factors related to poor outcomes. Area under the curve (AUC) of Model 1 was 0.93, 0.85 in HHG; 0.78 in Model 2, 0.65 in mFG, and 0.62 in MPV. @*Conclusion@#Although MPV differed significantly between the good and poor outcome groups, it is insufficient to predict poor outcomes in SAH patients as an independent biomarker.

Influencing factors for Sleep Disturbance in the Intensive Care Unit Patients: A Systematic Review / 중환자간호학회지

Purpose@#: Sleep disturbances in patients in the intensive care unit (ICU) are related to health problems after discharge. Therefore, active prevention and management are required. Hence, identification of the factors that affect sleep in patients who are critically ill is necessary. @*Methods@#: The PubMed, Cochrane Library, CINAHL, EMBASE, and Web of Science databases were searched. Selection criteria were observational and experimental studies that assessed sleep as an outcome, included adult patients admitted to the ICU, and published between November 2015 and April 2022. @*Results@#: A total of 21,136 articles were identified through search engines and manual searches, and 42 articles were selected. From these, 22 influencing factors and 11 interventions were identified. Individual factors included disease severity, age, pain, delirium, comorbidities, alcohol consumption, sex, sleep disturbance before hospitalization, chronic obstructive pulmonary disease (COPD), cardiovascular disease, and high diastolic blood pressure (DBP), low hemoglobin (Hb), and low respiratory rate (RR). Environmental factors included light level, noise level, and temperature. Furthermore, treatment-related factors included use of sedatives, melatonin administration, sleep management guidelines, ventilator application, nursing treatment, and length of ICU stay. Regarding sleep interventions, massage, eye mask and earplugs, quiet time and multicomponent protocols, aromatherapy, acupressure, sounds of the sea, adaptive intervention, circulation lighting, and single occupation in a room were identified. @*Conclusion@#: Based on these results, we propose the development and application of various interventions to improve sleep quality in patients who are critically ill.

The difference of the HEART score for predicting cardiovascular disease according to obesity index in emergency department

Objective@#The HEART score is a fast and simple cardiovascular disease (CVD) prediction tool useful in the emergency department (ED). This study evaluates the predictive value of the HEART score when applying other obesity indices such as waist circumference (WC) or waist-to-height ratio (WHtR) instead of body mass index (BMI). @*Methods@#Data were prospectively collected from the pre-made registry of patients who had visited the ED with chest pain. Based on their final diagnoses and coronary imaging study results, patients were classified as acute coronary syndrome (ACS), non-ACS, significant coronary arterial stenosis (SCS), and non-SCS. We compared the HEART score for each group and modified it with variable obesity indices. Multivariable logistic regression and the area under the curve were calculated to determine the most suitable obesity index for the HEART score in predicting ACS or SCS. In addition, we compared the gender-dependent relationship between obesity and ACS or SCS. @*Results@#Of the total 689 patients examined, 281 were diagnosed with ACS. The odds ratio (OR) of the HEART score for ACS was 12.1. The ORs were 13.2 and 11.2 when the HEART score was modified with WC or WHtR, respectively. Obesity was determined as the meaningful factor to predict ACS (OR: BMI, 2.38; WC, 3.39) and SCS (OR: BMI, 3.07; WC, 4.03) in women but not men. @*Conclusion@#The HEART score showed good predictive value regardless of obesity index modification. Furthermore, obesity is associated with CVD in women with chest pain, but not in men.

Characteristics and effects of high-flow nasal cannula oxygen therapy in patients with heart failure admitted to the emergency department

Objective@#This study aimed to compare the effects of high-flow nasal cannula (HFNC) treatment and conventional oxygen therapy (COT) in patients with heart failure (HF) admitted to the emergency department (ED). @*Methods@#This study was a single-center, retrospective, observational study. The subjects were divided into HFNC and COT groups. The characteristics were compared, and vital signs and arterial blood gas (ABG) results were analyzed. In addition, mortality, intubation rate, intensive care unit (ICU) admission, and length of stay (LOS) were analyzed for clinical outcome. @*Results@#Among 252 patients, 91 and 161 were treated with HFNC and COT. Two groups showed differences in vital signs, ABG results, and pulmonary edema. The HFNC group showed no difference in mortality and LOS, but more intubation and ICU admission were observed (P=0.005, P<0.001). Due to the changes in vital signs and ABG results, the HFNC group reduced blood pressure, heart rate and respiratory rate, improved SpO2, increased pH, and decreased PaCO2. @*Conclusion@#HFNC therapy effectively improved vital signs and ventilation when administered to relatively unstable patients with HF admitted to the ED.

Analysis on the ratio of emergency department visits by elderly and non-elderly patients based on disease and particulate matter concentration in South Korea: a multicenter cross-sectional observational study

Objective@#Many previous studies have reported relationships between particulate matter 80 μg/m3, and the PM10 values on the 5 following days were recorded. To assess the cumulative effects of PM10, we calculated relative risk (RR) by analyzing the cumulative effects over 6 days (lag days 0 to 5). @*Results@#Asthma, COPD, and ischemic stroke patients (< 65 years old) showed a positive correlation between PM10 (asthma on lag day 5: RR, 2.587; 95% confidence interval [CI], 2.001-3.344; COPD on lag day 4: RR, 3.727; 95% CI, 2.988-4.650; and ischemic stroke on lag day 4: RR, 1.573; 95% CI, 1.168-2.118). MI in those≥65 showed the highest RR on lag day 1 (RR, 1.471; 95% CI, 1.042-2.077). Hemorrhagic stroke was not found to be significantly correlated with PM10 in either age group. @*Conclusion@#An increase in PM10 is associated with ED visits by patients<65 years old with asthma, COPD, or ischemic stroke, and with MI for those≥65 years.

Acute Heart Failure after Oral Intake of Liquid Nicotine

A 32-year-old female patient was admitted to the hospital after drinking 10 mg of liquid nicotine. She complained of dizziness, nausea, and abdominal pain. The blood pressure was low but the heart rate and respiratory rate were within a normal range. Cardiac enzymes were increased. Echocardiography taken in the emergency room showed akinesia in the apex and the anterior wall, hypokinesia in the inferior and the posterior wall, and severe left ventricular systolic dysfunction with an ejection fraction of 20%. Blood pressure was continuously low after hydration so continuous intravenous norepinephrine and dobutamine were administrated. The patient was admitted to the intensive care unit for closed monitoring. Follow-up echocardiography was performed 4 days after admission. The heart was restored and the ejection fraction was recovered to 65%. There are not many studies about the toxicity of electronic cigarette’s nicotine and there are even fewer reports on the toxicity that occurs when liquid nicotine is orally taken. This is a report of a patient of an acute heart failure after intake of liquid nicotine used in the electronic cigarette.

The usefulness of cystatin C as a prognostic predictor in patients with heart failure admitted to the emergency department

Objective@#This study evaluated the usefulness of cystatin C as a prognostic predictor in heart failure patients admitted to the emergency department. @*Methods@#This study was conducted retrospectively on patients with heart failure admitted to the emergency department between January and December 2018. Patients newly and previously diagnosed with heart failure underwent both N-terminal prohormone of brain natriuretic peptide and cystatin C tests. To assess the patients’ prognosis, a poor prognosis was defined as the occurrence of one or more of the following events: intubation, admission to an intensive care unit, coronary angiography, continuous renal replacement therapy, extracorporeal membrane oxygenation, cardiopulmonary resuscitation, and death. The patients were divided into two groups based on the occurrence of these events; the characteristics between the groups with and without events were compared. @*Results@#Seventy-four patients were included in the study analysis: 35 and 39 in the group without and with events, respectively. The number of patients with a history of diabetes, hypertension, troponin T, and cystatin C levels were significantly higher in the group with events than in the group without events (P=0.028, P=0.041, P<0.001, and P=0.002, respectively). Multiple logistic regression analyses showed that cystatin C is a significant prognostic predictor of events. @*Conclusion@#An increased cystatin C level has been shown to clinically predict a poor prognosis of heart failure patients admitted to emergency departments.

The predictive value of HEART score for acute coronary syndrome and significant coronary artery stenosis

Objective@#Rapid determination of acute coronary syndrome (ACS) in the emergency department (ED) is very important for patients presenting with ischemic symptoms. The aim of this study was to determine the predictive value of HEART score for ACS and significant coronary artery stenosis (SCS). @*Methods@#We retrospectively analyzed data of patients who visited the ED with chest discomfort and were admitted to the cardiology department. Enrolled patients were classified into ACS and non-ACS groups according to their discharge diagnosis. Patients who underwent imaging were further divided into SCS and non-SCS groups according to study results. We compared age, sex, vital signs, risk factors, electrocardiogram, troponin, and HEART score for each group. For ACS and SCS predictive performance, the test characteristics of HEART score was calculated using sensitivity, specificity, predictive value, likelihood ratio, and receiver operating characteristic (ROC) curve analysis. @*Results@#Of 207 patients, 112 had ACS. Among enrolled patients, 155 underwent imaging workup, of whom 67 had SCS. HEART score ≤3 had 93% sensitivity for ACS and 97% for SCS. HEART score ≥7 had 82% specificity for ACS and 83% for SCS. HEART score area under ROC curve for ACS was 0.706 (95% confidence interval, 0.627–0.776) and 0.737 (95% confidence interval, 0.660–0.804) for SCS. @*Conclusion@#HEART score was a fair predictor of ACS and SCS in ED patients who presented with chest symptoms and were admitted to the cardiology department. The predictive power of HEART score was better for SCS than for ACS.

The predictive power of HEART score was better for SCS than for ACS.

Validation of quick sequential organ failure assessment score for poor outcome prediction among emergency department patients with suspected infection

OBJECTIVE: The quick sequential organ failure assessment (qSOFA) score, which includes mentation, systolic blood pressure, and respiratory rate, was developed to identify serious sepsis in out-of-hospital or emergency department (ED) settings. We evaluated the ability of the qSOFA score to predict poor outcome in South Korean ED patients with suspected infection.METHODS: The qSOFA score was calculated for adult ED patients with suspected infection. Patients who received intravenous or oral antibiotics in the ED were considered to have infection. In-hospital mortality rate, admission rate, intensive care unit (ICU) admission rate, length of hospital stay (LOS), and lactate levels were compared between the qSOFA score groups. Receiver operating characteristic curves and area under the receiver operating characteristic curve values for in-hospital mortality were calculated according to qSOFA cut-off points and lactate levels.RESULTS: Of 2,698 patients, in-hospital mortality occurred in 134 (5.0%). The mortality rate increased with increasing qSOFA score (2.2%, 6.4%, 17.5%, and 42.4% for qSOFA scores 0, 1, 2, and 3, respectively, P<0.001). The admission rate, ICU admission rate, LOS, and lactate level also increased with increasing qSOFA score (all P<0.001). The area under the receiver operating characteristic curve values for predicting in-hospital mortality associated with qSOFA score, lactate ≥2 mmol/L, and lactate ≥4 mmol/L were 0.719 (95% confidence interval [CI], 0.670 to 0.768), 0.657 (95% CI, 0.603 to 0.710), and 0.632 (95% CI, 0.571 to 0.693), respectively.CONCLUSION: Patients with a higher qSOFA score had higher admission, ICU admission, and in-hospital mortality rates, longer LOS, and higher lactate level. The qSOFA score showed better performance for predicting poor outcome than lactate level.

Risk Factors for Falls in Tertiary Hospital Inpatients: A Survival Analysis / 중환자간호학회지

PURPOSE: The purpose of this study was to identify the risk factors for falls in tertiary hospital inpatients and to suggest data for developing a nursing intervention program for preventing falls.METHODS: Data were collected between January 1, 2017, to December 31, 2017. Kaplan-Meier estimation was used to measure the survival rate, and the log-rank test was used for the differences between the fall group and the non-fall group. The Cox proportional hazards model was used to identify the risk factors for falls.RESULTS: The incidence rate of falls for the inpatients was 1.2 cases per 1,000 days of hospitalization. The risk factors for falls were more likely to be found among those who were aged ≥81, had not undergone surgery, had poor joint motion, had unsteady gait, needed help or supervision, used assistive devices, had comorbidity, and took at least two drugs.CONCLUSION: For the inpatients, the risk factors for falls included age, surgery, comorbidity, medication that could change mobility, joint motion, and use of patient care equipment. It is necessary to give special attention to inpatients who have any of these risk factors and to develop a falls risk assessment tool.

A Study of the Trends in Korean Nursing Research on Critical Care in the Last 10 Years (2008–2017) Using Integrated Review and Key Word Analysis / 중환자간호학회지

PURPOSE: The purpose of this study was to examine the possible direction of critical care nursing research in the future by analyzing the trends of recent Korean studies.METHOD: Using a database search, we selected 263 articles on critical care nursing that were published in Korean journals between 2008 and 2017. Then, we conducted an integrative review of the contents of the selected articles and analyzed the English abstracts using the relevant packages and functions of the R program.RESULTS: The number of studies concerning critical care nursing has increased over the 10-year period, and the specific topic of each study has diversified according to the time at which it was conducted. In terms of quality, the majority of the research was published in high-level academic journals. The key words regularly studied over the past decade were: knowledge, delirium, education, restraint, stress, and infection. Studies related to vancomycin-resistant enterococci infection, compliance, and standards have decreased, while studies related to death, communication, and safety have increased.CONCLUSION: Randomized controlled trials and protocol research for evidence-based critical care need to be conducted, as does research on family involvement. The key word analysis of unstructured text used in this study is a relatively new method; it is suggested that this method be applied to various critical care nursing research and develop it methodologically.

Instruments to Assess Physical Impairments in Post-Intensive Care Syndrome: A Systematic Review / 중환자간호학회지

PURPOSE: The purpose of this study was to systematically review the instruments utilized to assess physical impairment in post-intensive care syndrome (PICS) of intensive care unit (ICU) survivors.METHOD: Online databases searched were MEDLINE, Cochrane, CINAHL, and Embase. Studies that met the following criteria were included: 1) the study population exclusively had experience with ICU admission; 2) the study assessed pulmonary, neuromuscular, and physical functions; and 3) the study was published in English language journals after 2007.RESULTS: A total of 56 instruments (2 pulmonary, 25 neuromuscular, 29 physical function) from 94 studies were reviewed. They were classified into self-report, observation, and measurement according to the type of assessment. No instrument measured all 3 areas of physical impairment. Five instruments were originally developed for the ICU patients. The most frequently applied instruments were the Medical Research Council and the 36-item Short Form Survey (physical component summary), which were used in 23 studies each. Only 13.8% of reviewed studies reported the reliability or validity of the instruments.CONCLUSION: Our results suggest that the appropriateness of instruments assessing physical impairment in PICS cannot be guaranteed. Despite the multidimensional concept of physical disabilities, most studies measured only one area, and studies that reported psychometric properties were limited. Accordingly, we propose to develop a unique and multifaceted instrument for ICU survivors.

Development and Validation of a Measurement to Assess Person-centered Critical Care Nursing

PURPOSE: The purpose of this study was to develop a scale to measure person-centered critical care nursing and verify its reliability and validity. METHODS: A total of 38 preliminary items on person-centered critical care nursing were selected using content validity analysis of and expert opinion on 72 candidate items derived through literature review and qualitative interviews. We conducted a questionnaire survey with 477 nurses who worked in intensive care units. The collected data were analyzed using exploratory factor analysis (EFA) and confirmative factor analysis (CFA) with SPSS and AMOS 24.0 program. RESULTS: EFA was performed with principal axis factor analysis and Varimax rotation. The 15 items in 4 factors that accounted for 50.8% of the total variance were identified by deleting the items that were not meet the condition that the commonality should be .30 or more and the factor loading over .40. We named the factors as compassion, individuality, respect, and comfort, respectively. The correlation coefficient between this scale and the Caring Perception Scale was r=.57 (p < .001), which determined concurrent validity. The item-total correlation values ranged from .39 to .63, and the internal consistency for the scale was Cronbach's α=.84. CONCLUSION: The reliability and validity of the 15 item person-centered critical care nursing scale were verified. It is expected that the use of this scale would expand person-centered care in critical care nursing.

Survey of emergency medicine residency education programs and suggestion for improvement on the future emergency medicine residency education

OBJECTIVE: This study examined the educational programs for emergency residency in The Korean Society of Emergency Medicine. METHODS: A written survey of the workshop programs with representatives of the related organizations and affiliated organizations was conducted. During the 5-year period, the number of training courses and workshops attended by those who took the professional examination were analyzed. RESULTS: There were 23 workshops in progress. They proceed 2.85 times a year on average. The average number of participants was 22.8 with an average time required for the workshop of 5.6 hours, of which 78.7% is practice time. They received feedback from residency at all workshops, which was reflected in the process. During the 5-year period, the average number of participant training courses was 3.8, and the average number of workshop participants was 2.7. CONCLUSION: The education program for emergency residency is continuing through the affiliated organizations and related organizations as well as The Korean Society of Emergency Medicine. Encouraging opportunities for participation in various educational programs to supplement those that are not fully experienced will be helpful.

Evaluation of Validity and Reliability of Inertial Measurement Unit-Based Gait Analysis Systems

OBJECTIVE: To replace camera-based three-dimensional motion analyzers which are widely used to analyze body movements and gait but are also costly and require a large dedicated space, this study evaluates the validity and reliability of inertial measurement unit (IMU)-based systems by analyzing their spatio-temporal and kinematic measurement parameters. METHODS: The investigation was conducted in three separate hospitals with three healthy participants. IMUs were attached to the abdomen as well as the thigh, shank, and foot of both legs of each participant. Each participant then completed a 10-m gait course 10 times. During each gait cycle, the hips, knees, and ankle joints were observed from the sagittal, frontal, and transverse planes. The experiments were conducted with both a camerabased system and an IMU-based system. The measured gait analysis data were evaluated for validity and reliability using root mean square error (RMSE) and intraclass correlation coefficient (ICC) analyses. RESULTS: The differences between the RMSE values of the two systems determined through kinematic parameters ranged from a minimum of 1.83 to a maximum of 3.98 with a tolerance close to 1%. The results of this study also confirmed the reliability of the IMU-based system, and all of the variables showed a statistically high ICC. CONCLUSION: These results confirmed that IMU-based systems can reliably replace camera-based systems for clinical body motion and gait analyses.

Post-Intensive Care Syndrome Experience among Critical Care Survivors: A Meta-synthesis of Qualitative Research / 중환자간호학회지

PURPOSE: The purpose of this study was to integrate the results of qualitative studies to understand critical care survivors' experience of the post-intensive care syndrome (PICS).METHODS: This was a meta-synthesis of primary studies that used qualitative methods. We reviewed 26 qualitative studies on PICS selected from 8 international and Korean databases and from a manual search. Thomas and Harden's 3 stages (free coding, development of descriptive themes, generation of analytical themes) for thematic synthesis were utilized to analyze the collected qualitative data.RESULTS: Four descriptive themes emerged from the thematic synthesis: weak physical conditions, psycho-emotional changes, the painful-memory of intensive care units, and social vulnerability. The analytical theme for the current study was “unfamiliarity with the vulnerable self.” Critical care survivors had to confront entirely different “selves” after discharge from intensive care units. They had become physically weak, psychologically unstable, and the critical memories continued to create distress. These changes increased their social vulnerability by making them dependent on others, causing family conflicts, and changing interpersonal relationships.CONCLUSIONS: Finding from this qualitative synthesis and other related literature highlight the severity of PICS and the importance of rehabilitative intervention for critical care survivors.

Usefulness of Neurtiophil Gelatinase-Associated Lipocalin as a Prognosis Predictor in Heart Failure Patients in Emergency Department

PURPOSE: We aimed to investigate the clinical use of plasma neutrophil gelatinase-associated lipocalin (NGAL) in the emergency department (ED), especially for predicting the prognosis of heart failure. METHODS: In a retrospective study, patient selection was based on those who visited the ED between January 2015 and September 2015 and were diagnosed with heart failure and underwent laboratory tests, including B-type natriuretic peptide (BNP) and NGAL. They were divided in two groups, according to the presence or absence of the following events: one or more intubations, admission of intensive care unit (ICU), coronary angiography, renal replacement therapy, extracorporeal membrane oxygenation, intra-aortic balloon pumping, cardiopulmonary resuscitation (CPR), or death. RESULTS: We studied 63 patients with heart failure. The absence group consisted of 29 subjects, and the presence group consisted of 34 subjects. Patients who were younger, had a history of diabetes mellitus, had high level of serum creatinine, low estimated glomerular filtration (eGFR), high creatine kinase (CK) or high NGAL were associated with higher incidence of events and were statistically significant (p<0.001, 0.02, 0.005, 0.035, 0.03, 0.003). In the case of BNP, the presence group showed a higher value compared with the absence group, but was not statistically significant. In a multivariated logistic regression, age (OR=0.868, 95% confidence interval 0.788-0.956, p=0.004) and NGAL (OR=1.004, 95%CI 1.001-1.007, p=0.021) were considered as meaningful factors for predicting the event. CONCLUSION: NGAL elevation in this study showed to be a meaningful factor, indicating a prognosis to those patients who visited the ED and were diagnosed as heart failure.

Utility of the APACHE II Score as a Neurologic Prognostic Factor for Glufosinate Intoxicated Patients

PURPOSE: The incidence of glufosinate poisoning is gradually increasing, and it can be fatal if severe poisoning occurs. However, factors useful for predicting the post-discharge neurological prognosis of patients who have ingested glufosinate have yet to be identified. Our objective was to evaluate the utility of the acute physiology and chronic health evaluation (APACHE) II score measured in the emergency department for predicting the neurological prognosis. METHODS: From April 2012 to August 2014, we conducted a retrospective study of patients who had ingested glufosinate. The outcome of the patients at discharge was defined by the Cerebral Performance Category Score (CPC). The patients were divided into a good prognosis group (CPC 1, 2) and a poor prognosis group (CPC 3, 4, 5), after which the APACHE II scores were compared. The Hosmer-Lemeshow test and the area under the receiver operating characteristic (ROC) curve from patients determined calibration and discrimination. RESULTS: A total of 76 patients were enrolled (good prognosis group: 67 vs poor prognosis group: 9). The cut-off value for the APACHE II score was 12 and the area under the curve value was 0.891. The Hosmer and Lemeshow C statistic χ2 was 7.414 (p=0.387), indicating good calibration for APACHE II. CONCLUSION: The APACHE II score is useful at predicting the neurological prognosis of patients who have ingested glufosinate.

Have You Ever Suspected Stercoral Perforation?: A Case Report

Diagnosis and management of abdominal pain in old age is considered a challenge to emergency physicians. Stercoral perforation is an infrequent event, which most commonly develops in old age. We report on a case of stercoral perforation in an elderly woman, which, to the best of our knowledge, is one of a few reported cases in the medical literature. A 74-year-old woman who presented at our emergency department complaining of lower abdominal pain was found to have a perforation of the colon. Examination revealed a stercoral perforation by fecaloma. She underwent Hartman's operation and colostomy. Stercoral perforation is rare; however, emergency physicians should consider this disease entity in elderly patients with abdominal pain.
