Background and aims Studies concerning the impact of air temperature on esophagogastric variceal bleeding (EGVB) have yielded conflicting results. Our study aimed to evaluate the correlation between air temperature and EGVB. Methods A time-stratified case-crossover study design was performed. Patients received emergency gastroscopic hemostasis for upper gastrointestinal bleeding between Jan 1, 2014, and Dec 31, 2018 in the Fifth Medical Center of PLA General Hospital were enrolled. Conditional logistic regression analysis was applied to determine the association between air temperature and EGVB for different lag structures. Results A total of 4204 cirrhotic patients diagnosed with EGVB and received emergency gastroscopic hemostasis were enrolled. The mean number of daily EGVB cases peaked in October (2.65 ± 1.69) and fell to the lowest level in July (1.86 ± 1.38), and was 2.38 ± 1.58 in spring, 2.00 ± 1.46 in summer, 2.37 ± 1.58 in autumn, and 2.45 ± 1.58 in winter, respectively (P < 0.0001). In conditional logistic regression analysis, no significant correlations between air temperature and EGVB were observed and no significant difference were found when stratified by age, sex, etiology, liver cancer status, and grade of varices. Conclusion Emergency admission for EGVB showed significant monthly and seasonal fluctuations, while in conditional logistic regression analysis, no association between minimum temperature and emergency admission for EGVB were observed....
Background Fall injuries and trauma-related hospitalizations are the most common causes of injury and in-hospital stay amongst the elderly population. After the age of 65, the severity and frequency of fall-related problems increases; the repercussions are challenging for senior citizens, caregivers, and healthcare professionals. This study aims to determine the injuries and outcomes resulting from falls in elderly patients presenting to Emergency Department of a tertiary care hospital. Methods A cohort study design was used. All elderly patients aged ≥ 60 years who visit the Emergency Department with a history of a fall as a primary complaint presenting to the ED of a tertiary care hospital in Karachi, Pakistan were included. A purposive sampling strategy was used to enroll 318 patients from August 2021 to February 2022. The outcome was risk of mortality. Each individual was followed for 90 days to study the outcome. A multivariable logistic regression was applied to check the association between the outcome and covariates. Crude and adjusted risk ratios were reported. A p-value ≤ 0.05 was considered significant. Results Of the 318 participants, 265 (83.3%) were fall injury patients with comorbidities. More than half of the patients in both groups were female [32 (60.4%) & 146 (55.1%)]. Eyeglasses were used by most of the fall patients both without and with comorbidities [21 (39.6%) & 152 (57.4%) p 0.018]. There were multiple reasons for a fall including imbalance/dizziness, which was reported by one third of participants in both groups [15 (28.3%) & 77 (29.1%)] followed by a fall from stairs/steps/escalator [15 (28.3%) & 44 (16.6%) p 0.005]. At the end of one month, of those who had a comorbidity 20 (7.5%) expired. The risk of mortality among fall related injuries in elderly patients who were more than 80 years was 1.48 times (95% CI: 1.20–2.10) more likely when compared to those patients who were younger than 80 years. Conclusion Efforts should be made to improve management of the underlying etiology of falls to prevent them in future. The factors that contribute to falls should be identified. Strategies and interventions should be planned to mitigate this risk of fall in elderly to improve their quality of life....
Background Since 2014, Korea has been operating the National Emergency Medical Situation Room (NEMSR) to provide regional emergency departments (EDs) with coordination services for the interhospital transfer of critically ill patients. The present study aimed to describe the NEMSR’s experience and interhospital transfer pattern from EDs nationwide, and investigate the factors related to delayed transfers or transfers that could not be arranged by the NEMSR. Methods This study was a retrospective cross-sectional analysis of the NEMSR’s coordination registry from 2017 to 2019. The demographic and hospital characteristics related to emergency transfers were analyzed with hierarchical logistic models. Results The NEMSR received a total of 14,003 requests for the arrangement of the interhospital transfers of critically ill patients from 2017 to 2019. Of 10,222 requests included in the analysis, 8297 (81.17%) successful transfers were coordinated by the NEMSR. Transfers were requested mainly due to a shortage of medical staff (59.79%) and ICU beds (30.80%). Delayed transfers were significantly associated with insufficient hospital resources. The larger the bed capacity of the sending hospital, the more difficult it was to coordinate the transfer (odds ratio [OR] for transfer not arranged = 2.04; 95% confidence interval [CI]: 1.48–2.82, ≥ 1000 beds vs. < 300 beds) and the longer the transfer was delayed (OR for delays of more than 44 minutes = 2.08; 95% CI: 1.57–2.76, ≥ 1000 beds vs. < 300 beds). Conclusions The operation of the NEMSR has clinical importance in that it could efficiently coordinate interhospital transfers through a protocolized process and resource information system. The coordination role is significant as information technology in emergency care develops while regional gaps in the distribution of medical resources widen....
Background Deciding whether to transfer patients with sepsis from the emergency department (ED) to intensive care units (ICUs) is challenging. We hypothesised that the new biomarker plasma calprotectin (p-calprotectin) could be used to aid the selection of patients for intensive care transfer, since it has been shown to be a promising tool for the determination of sepsis severity in critical care. Methods This prospective study was performed on consecutive sepsis alert patients in the ED of Karolinska University Hospital Huddinge. The sepsis alert mandates clinical assessment and decisions regarding treatment, disposition, and level of care by physicians from the ED, the Department of Infectious Diseases, and the ICU. Blood sample analysis for C-reactive protein, procalcitonin, neutrophils, and lymphocytes was routinely performed. P-calprotectin was analysed from frozen plasma samples, using a specific turbidimetric assay. Results Three-hundred fifty-one patients who triggered the sepsis alert were available for the study. Among 319 patients who were considered to have an infection, 66 patients (26%) were immediately transferred to the ICU or high-dependency unit (HDU), and 253 patients (74%) were transferred to ordinary wards. Median p-calprotectin was 2.2 mg/L (IQR 1.2–3.9 mg/L) for all patients with infection, it was 3.3 (IQR 1.6–5.2) for those transferred to ICU/HDU and 2.1 (IQR 1.1–3.5) for those transferred to ward units (p = 0.0001). Receiver operating characteristic curve analysis for transfer to the ICU/HDU showed superiority for p-calprotectin compared with procalcitonin and neutrophil–lymphocyte ratio, regarding both all sepsis alert cases and the patients with infection (p < 0.001 for all comparisons). The best p-calprotectin cut-off, 4.0 mg/L, showed a sensitivity of 42.5% and specificity of 83% for transfer to the ICU/HDU among patients with infection. Conclusions In sepsis alert patients, p-calprotectin was significantly elevated in patients who were subject to immediate ICU/HDU transfer after assessment by a multidisciplinary team. P-calprotectin was superior to traditional biomarkers in predicting the need for transfer to the ICU/HDU....
Purpose Emergency physicians are in danger of developing illnesses due to stress in their demanding work environment. Until today, scholars have not identified stressors or resilience factors that qualify to promote the preservation of emergency physicians’ well-being. Therefore, potential influencing variables such as patients’ diagnoses, the severity of diagnoses, as well as physicians’ work experience have to be considered. The present study aims at investigating emergency physicians in the Helicopter Emergency Medical Service (HEMS)’ autonomic nervous system activity during emergency operations in one shift with respect to patients’ diagnoses, severity of diagnoses, and physicians’ work experience. Methods Measurement of HRV (employing the parameters RMSSD and LF/HF) for 59 EPs (age: M = 39.69, SD = 6.19) was performed during two complete air-rescue-days, the alarm and landing phase being investigated in particular. Besides patients’ diagnoses, the National Advisory Committee for Aeronautics Score (NACA) was included as an indicator for severity. Diagnoses’ and NACA’s effect on HRV were examined using a linear mixed model. Results Both HRV parameters indicate a significant decrease of the parasympathetic nervous system as a function of the diagnoses. Furthermore, high NACA scores (≥ V) predicted a significantly lower HRV. In addition, a lower HRV/ RMSSD with increasing work experience was observed as well as a positive association between physicians’ work experience and sympathetic activation (LF/HF). Conclusion The present study showed that pediatric diagnoses as well as time-critical diagnoses are most stressful and have the highest impact on the physicians’ ANS. This knowledge allows the development of specific training to reduce stress....
