The scores of accuracy ratings for triage nurses can be improved if factors contributing to inaccuracy can be altered. The findings of this study can be used to guide improvements.
Acute mountain sickness (AMS) is a pathophysiological symptom complex that occurs in high altitude areas. The AMS prevalence is reportedly 28% on Jade Mountain, the highest mountain (3952 m) in Taiwan. We conducted this study owing to the lack of annual epidemiological data on AMS in Taiwan. Between April 2007 and March 2008, 1066 questionnaires were completed by trekkers visiting Paiyun Lodge on Jade Mountain. Information in the questionnaire included demographic data, mountaineering experience, AMS history, and trekking schedule. Weather data were obtained from the Central Weather Bureau of Taiwan. The Lake Louise AMS score was used to record symptoms and diagnose AMS. The chi-square test or the Student t test was used to evaluate associations between variables and AMS. In our study, the AMS prevalence was 36%. It increased significantly at different rates at different locations on the Jade Mountain trail and varied significantly in different months. Rainy weather tended to slightly increase the incidence of AMS. A lower incidence of AMS was correlated with hig-altitude trekking experience or preexposure (p < 0.05), whereas a higher incidence of AMS was correlated with a prior history of AMS (p < 0.05). The trekkers with AMS were significantly younger, ascended faster from their residence to the entrance or to Paiyun Lodge, and ascended slower from the entrance to the Paiyun Lodge (p < 0.05), but the differences lacked clinical significance. No differences in the incidence of AMS based on blood type, gender, or obesity were observed. The most common symptom among all trekkers was headache, followed by difficulty sleeping, fatigue or weakness, gastrointestinal (GI) symptoms, and dizziness or lightheadedness. In conclusion, the AMS prevalence on Jade Mountain was 36%, varied by month, and correlated with trekking experience, preexposure, and a prior history of AMS. The overall presentation of AMS was similar to that on other major world mountains.
chip-Jin ng 1 ✉ cardiopulmonary resuscitation (cpR) training and its quality are critical in improving the survival rate of cardiac arrest. This randomized controlled study investigated the efficacy of a newly developed CPR training program for the public in a Taiwanese setting. A total of 832 adults were randomized to either a traditional or blended (18-minute e-learning plus 30-minute hands-on) compression-only CPR training program. The primary outcome was compression depth. Secondary outcomes included CPR knowledge test, practical test, quality of CPR performance, and skill retention. The mean compression depth was 5.21 cm and 5.24 cm in the blended and traditional groups, respectively. The mean difference in compression depth between groups was −0.04 (95% confidence interval −0.13 to infinity), demonstrating that the blended CPR training program was non-inferior to the traditional CPR training program in compression depth after initial training. Secondary outcome results were comparable between groups. Although the mean compression depth and rate were guideline-compliant, only half of the compressions were delivered with adequate depth and rate in both groups. CPR knowledge and skill retained similarly in both groups at 6 and 12 months after training. The blended CPR training program was non-inferior to the traditional CPR training program. However, there is still room for improvement in optimizing initial skill performance as well as skill retention. Clinical Trial Registration: NCT03586752; www.clinicaltrial.gov The survival rate of out-of-hospital cardiac arrest (OHCA) is low. In the United States, it has remained between 7% and 9% for the past decades 1. Meanwhile the 180-day OHCA survival rate was reported to be 9.8% in Taiwan 2. Early defibrillation is a treatment option that can increase OHCA survival rate and survival outcomes 3. Ever since its promotion by the American Heart Association (AHA) 4 , many countries have installed automated external defibrillators (AEDs) in public or private places including tourists spots, shopping malls, airports, casinos, schools, offices and so forth, with increased coverage and accessibility. In Taiwan, up until 2017, a total of 8334 AEDs had been installed nationwide 5. Wang et al. 5 reported that, among the documented OHCA cases with AEDs used, 35% were known to be operated by the employees at the designated AED locations, and long-term care facilities had the highest utilization rate of AED. In addition, high-quality chest compressions during cardiopulmonary resuscitation (CPR) also improve OHCA patient outcomes 6-8. However, studies have shown the quality of CPR to be substandard 9,10. Therefore, training with a focus on cardiopulmonary resuscitation (CPR) quality and AED should be implemented and provided, particularly at the AED locations of high cardiac arrest frequency.
IntroductionBacterial infection can cause sepsis [1]. Sepsis with acute organ dysfunction, namely severe sepsis [1], is a major threat to life [2]. Early institution of an appropriate antimicrobial regimen in infected patients is associated with a better outcome [3], and hence early diagnosis of bacterial infection is of primary importance. However, some patients with an infection have minimal or even no symptoms or signs. Not all patients who appear septic demonstrate an infection, and the widespread administration of antibiotics to all these patients APACHE = Acute Physiology and Chronic Health Evaluation; AUC = area under the receiver operating characteristic curve; BT = body temperature; CRP = C-reactive protein; ED = emergency department; IL = interleukin; NPV = negative predictive value; PCT = procalcitonin; PPV = positive predictive value; SIRS = systemic inflammatory response syndrome; TNF-α = tumor necrosis factor alpha; WBC, white blood cell. AbstractIntroduction Procalcitonin (PCT) has been proposed as a marker of infection in critically ill patients; its level is related to the severity of infection. We evaluated the value of PCT as a marker of bacterial infection for emergency department patients. Methods This prospective observational study consecutively enrolled 120 adult atraumatic patients admitted through the emergency department of a 3000-bed tertiary university hospital in May 2001. Fifty-eight patients were infected and 49 patients were not infected. The white blood cell counts, the serum C-reactive protein (CRP) level (mg/l), and the PCT level (ng/ml) were compared between the infected and noninfected groups of patients. Results A white blood cell count >12,000/mm 3 or <4000/mm 3 was present in 36.2% of the infected patients and in 18.4% of the noninfected patients. The best cut-off serum levels for PCT and CRP, identified using the Youden's Index, were 0.6 ng/ml and 60 mg/l, respectively. Compared with CRP, PCT had a comparable sensitivity (69.5% versus 67.2%), a lower specificity (64.6% versus 93.9%), and a lower area under the receiver operating characteristic curve (0.689 versus 0.879). PCT levels, but not CRP levels, were significantly higher in bacteremic and septic shock patients. Multivariate logistic regression identified that a PCT level ≥ 2.6 ng/ml was independently associated with the development of septic shock (odds ratio, 38.3; 95% confidence interval, 5.6-263.5; P < 0.001). Conclusions PCT is not a better marker of bacterial infection than CRP for adult emergency department patients, but it is a useful marker of the severity of infection.
ObjectivesThis study aimed to determine the inter-rater reliability of the five-level Taiwan Triage and Acuity Scale (TTAS) when used by emergency medical technicians (EMTs) and triage registered nurses (TRNs). Furthermore, it sought to validate the prehospital TTAS scores according to ED hospitalisation rates and medical resource consumption.MethodsThis was a prospective observational study. After training in five-level triage, EMTs triaged patients arriving to the ED and agreement with the nurse triage (TRN) was assessed. Subsequently, these trained research EMTs rode along on ambulance calls and assigned TTAS scores for each patient at the scene, while the on-duty EMTs applied their standard two-tier prehospital triage scale and followed standard practice, blinded to the TTAS scores. The accuracy of the TTAS scores in the field for prediction of hospitalisation and medical resource consumption were analysed using logistic regression and a linear model, respectively, and compared with the accuracy of the current two-tier prehospital triage scale.ResultsAfter EMT’s underwent initial training in five-level TTAS, inter-rater agreement between EMTs and TRNs for triage of ED patients was very good (κw=0.825, CI 0.750 to 0.900). For the outcome of hospitalisation, TTAS five-level system (Akaike’s Information Criteria (AIC)=486, area under the curve (AUC)=0.75) showed better discrimination compared with TPTS two-level system (AIC=508, AUC=0.66). Triage assignments by the EMTs using the the five-level TTAS was linearly associated with hospitalisation and medical resource consumption.ConclusionsA five-level prehospital triage scale shows good inter-rater reliability and superior discrimination compared with the two-level system for prediction of hospitalisation and medical resource requirements.

High Alt. Med Biol. 10:77-82, 2009.-Medical problems requiring mountain rescue in densely populated and low-latitude locations like Taiwan have rarely been studied or discussed. The purpose of this research was to examine mountain-rescue operations that occurred in Yu-Shan National Park Taiwan from 1985 to 2007. Of 186 mountain-rescue operations, 128 involved medical problems (illnesses or injuries). Of the medical problems, 62% involved trauma and 41% involved illness. Ninety-nine ground rescues, 14 helicopter rescues, 38 combination ground and helicopter rescues, and 20 rescues using unclear methods were conducted, and the remaining 15 rescue operations did not involve visitors. In the 186 rescue operations, 330 visitors were rescued, 240 of them survived, 66 were dead, and 24 had an unclear outcome. Factors that affected the type of injury or the probability of survival included the activity, altitude, composition of the visitor group, weather, and occurrence of natural disasters. Mountain-rescue operations in which both ground and helicopter rescue were utilized were more successful. Our retrospective findings indicate that wilderness emergency services should have the capability of performing rescues in rugged terrain and be flexible in their approach to any situation arising in mountainous regions; proper training of onboard helicopter medical personnel is also necessary. In conclusion, we recommend setting up a standard system for reporting mountain- rescue operations, with statistics compiled annually.
