An intelligent emergency service( IES) system is designed for indoor environments based on a wireless sensor and actuator network( WSAN) composed of a gateway, sensor nodes, and a multi-robot system( MRS). If the MRS receives accident alarm information, the group of robots will navigate to the accident sites and provide corresponding emergency services.According to the characteristics of the MRS, a distributed consensus formation protocol is designed, which can assure that the multiple robots arrive at the accident site in a specified formation. The prototype emergency service system was designed and implemented, and some relevant simulations and experiments were carried out. The results showthat the MRS can successfully provide emergency lighting and failure node replacement services when accidents happen. The effectiveness of the algorithm and the feasibility of the system are verified. 展开更多

In recent years, the application of the Internet of Things (IoT) has become an emerging business. The most important concept of next-generation network for providing a common global IT platform is combining seamless networks and networked things, objects or sensors. Also, wireless body area networks (WBANs) are becoming mature with the widespread usage of the IoT. In order to support WBAN, the platform, scenario and emergency service are necessary due to the sensors in WBAN being related to wearer&#39;s life. The sensors on the body detect a lot of information about bioinformatics and medical signals, such as heartbeat and blood. Thus, the integration of IoT and network communication in daily life is important. However, there is not only a lack of common fabric for integrating IoT with current Internet and but also no emergency call process in the current network communication envi-ronment. To overcome such situations, the prototype of integrating IoT and emergency call process is discussed. A simulated boot-strap platform to provide the discussion of open challenges and solutions for deploying IoT in Internet and the emergency commu-nication system are analyzed by using a service of 3GPP IP multimedia subsystem. Finally, the prototype for supporting WBAN with emergence service is also addressed and the performance results are useful to service providers and network operators that they can estimate their migration to IoT by referring to this experience and experiment results. Furthermore, the queuing model used to achieve the performance of emergency service in IMS and the delay time of the proposed model is analyzed. 展开更多

Objective: The objective of the study was to identify facilitators and barriers to emergency medical service use among acute ischemic stroke patients in Korea.Methods: This paper presents a secondary analysis of a retrospective survey that collected data from questionnaires and medical records.Among 233 acute ischemic stroke patients enrolled in a large-scale study,160 patients who had arrived at a hospital within 72 h after symptom onset were included in the data analysis.Results: Users of emergency medical services needed a shorter time than non-users to arrive at hospital (140 min vs.625 min.,p =0.001) and were more likely to arrive at hospital within 3 h of symptom onset (51.9% vs.31.5%,p =0.013).For those who first contacted emergency medical service,the facilitators of emergency medical service use were the presence of hemiparesis (p =0.003),bilateral paralysis (p =0.040),and loss of balance (p =0.021).The predominant barrier was the failure to recognize the urgency of symptoms (p 0.006).Conclusions: The use of emergency medical services reduced prehospital delay and increased the likelihood of patient arrival at hospital within 3 h.Given that experiencing typical stroke symptoms was a facilitator of emergency medical service use yet failure to recognize the urgency of symptoms was a barrier,public awareness should be raised as regards stroke symptoms and the benefits of using emergency medical services. 展开更多

BACKGROUND: The purpose of the study was to explore the association between posttraumatic stress disorder(PTSD) and work performance of emergency medical services personnel in Karachi, Pakistan.METHODS: Emergency medical service personnel were screened for potential PTSD using Impact of Event Scale-Revised(IES-R). Work performance was assessed on the basis of fi ve variables: number of late arrivals to work, number of days absent, number of days sick, adherence to protocol, and patient satisfaction over a period of 3 months. In order to model outcomes like the number of late arrivals to work, days absent and days late, negative binomial regression was applied, whereas logistic regression was applied for adherence to protocol and linear for patient satisfaction scores.RESULTS: Mean scores of PTSD were 24.0±12.2. No association was found between PTSD and work performance measures: number of late arrivals to work(RRadj 0.99; 0.98–1.00), days absent(RRadj 0.98; 0.96–0.99), days sick(RRadj 0.99; 0.98–1.00), adherence to protocol(ORadj 1.01; 0.99–1.04) and patient satisfaction(β 0.001%–0.03%) after adjusting for years of formal schooling, living status, coping mechanism, social support, working hours, years of experience and anxiety or depression.CONCLUSION: No statistically significant association was found between PTSD and work performance amongst EMS personnel in Karachi, Pakistan. 展开更多

BACKGROUND:In Shenzhen, the Emergency Medical Service (EMS) system has been in service since 1997. This study aims to examine the operation of Shenzhen 120 EMS center and to identify the reasons of calling EMS.BACKGROUND:In this retrospective quantitative descriptive study, the data from the Shenzhen 120 EMS registry in 2011 were analyzed.RESULTS:Shenzhen 120 EMS center is a communication command center. When the number of 120 are dialed, it is forwarded to the closest appropriate hospital for ambulance dispatch. In 2011, the Shenzhen 120 EMS center received 153 160 ambulance calls, with an average of 420 calls per day. Calling emergency services was mainly due to traffic accidents. Trauma and other acute diseases constituted a majority of ambulance transports. The adult patients aged 15-60 years are the principal users of EMS. There are no recognized 'paramedic' doctors and nurses. The pre-hospital emergency service is under the operation of emergency departments of hospitals. Shenzhen at present does not have specialized pre-hospital training for doctors and nurses in posttrauma management. Moreover, specialized pre-hospital training, financial support, and public health education on proper use of EMS should be emphasized.CONCLUSION:The Shenzhen 120 EMS center has its own epidemiology characteristics. Traumatic injury and traffic accident are the main reasons for calling ambulance service. In-depth study emphasizing the distribution and characteristics of trauma patients is crucial to the future development of EMS. 展开更多

Background: This study aimed to evaluate the level of professional satisfaction, to identify the presence of psychic suffering and their correlations in Emergency Medical Services professionals. Methods: The study is of the exploratory, census, descriptive, transversal type, with quantitative approach. It used three instruments: A sociodemographic questionnaire;the Professional Satisfaction Index—PSI;and the Self Report Questionnaire—SRQ-20. 200 professionals took part in the research (doctors, nurses, nursing technicians and conductors). Results: The data show that the majority of professionals are aged between 40 and 49 years old and that the largest quantity of women belong to the group of nurses. As to the PSI, the majority of professionals pointed out remuneration as the most important for satisfaction. In the overall satisfaction result, the physicians were those who had the highest level of satisfaction. Regarding the SRQ-20 scores, the group of nursing technicians and nurses had the highest prevalence for psychic suffering, with 44.56% and 43.48%. In the statistical analyses between each of the components of the professional satisfaction with the SRQ-20 scores, we verified statistically significant correlations when adopting (p Conclusions: It was concluded that the discontent of workers with remuneration and managerial issues are predominant for total dissatisfaction with work and dissatisfaction exerts a strong influence on the presence of suffering in these professionals. 展开更多

BACKGROUND:Beijing 2022 Olympic Winter Games was the second Games held amid the COVID-19 pandemic.To a certain extent,it has altered the way sporting activities operate.There is a lack of knowledge on injury risk and illness occurrence in elite winter sport athletes amid the COVID-19 pandemic.This study aimed to describe the incidence of injuries and illnesses sustained during the XXIV Olympic Winter Games in Beijing from February 4 to 20,2022.METHODS:We recorded the daily number of injuries and illnesses among athletes reported by Beijing 2022 medical staff in the polyclinic,medical venues,and ambulance.We calculated injury and illness incidence as the number of injuries or illnesses occurring during competition or training,respectively,with incidence presented as injuries/illnesses per 100 athlete-days.RESULTS:In total,2,897 athletes from 91 nations experienced injury or illness.Beijing 2022 medical staff reported 326 injuries and 80 illnesses,equaling 11.3 injuries and 2.8 illnesses per 100 athletes over the 17-day period.Altogether,11%of the athletes incurred at least one injury and nearly 3%incurred at least one illness.The number of injured athletes was highest in the skating sports(n=104),followed by alpine skiing(n=53),ice track(n=37),freestyle skiing(n=36),and ice hockey(n=35),and was the lowest in the Nordic skiing disciplines(n=20).Of the 326 injuries,14(4.3%)led to an estimated absence from training or competition of more than 1 week.A total of 52 injured athletes were transferred to hospitals for further care.The number of athletes with illness(n=80)was the highest for skating(n=33)and Nordic skiing(n=22).A total of 50 illnesses(62.5%)were admitted to the department of dentistry/ophthalmology/otolaryngology,and the most common cause of illness was other causes,including preexisting illness and medicine(n=52,65%).CONCLUSION:Overall,11%of athletes incurred at least one injury during the Games,which is similar to the findings during the Olympic Winter Games in 2014 and 2018.Regarding illness,2%of athletes were affected,which is approximately one-third of the number affected in the 2018 Olympic Winter Games. 展开更多

AIM:To evaluate the main factors associated with mortality in patients undergoing surgery for perforated peptic ulcer referred to an academic department of general surgery in a large southern Italian city. METHODS:One hundred and forty-nine consecutive patients (M:F ratio=110:39,mean age 52 yrs,range 16-95) with peptic ulcer disease were investigated for clinical history (including age,sex,previous history of peptic ulcer,associated diseases,delayed abdominal surgery,ulcer site,operation type,shock on admission,postoperative general complications, and intra-abdominal and/or wound infections),serum analyses and radiological findings. RESULTS:The overall mortality rate was 4.0%.Among all factors,an age above 65 years,one or more associated diseases,delayed abdominal surgery,shock on admission, postoperative abdominal complications and/or wound infections,were significantly associated (x^2) with increased mortality in patients undergoing surgery (0.0001<P<0.03). CONCLUSION:Factors such as concomitant diseases,shock on admission,delayed surgery,and postoperative abdominal and wound infections are significantly associated with fatal outcomes and need careful evaluation within the general workup of patients admitted for perforated peptic ulcer. 展开更多

The oil spill forecast system includes an ocean environmental forecast model and an oil spill model. The ocean environmental forecast model was designed to include timesaving methods, and comprised a parametrical wind wave forecast model and a sea surface current forecast model. The oil spill model was based on the "particle method" and fulfi lls the prediction of oil particle behavior by considering the drifting, evaporation and emulsifi cation processes. A specifi c database was embedded into the oil spill forecast system, which contained fundamental information, such as the properties of oil, reserve of emergency equipment and distribution of marine petroleum platform. The oil spill forecast system was successfully applied as part of an oil spill emergency exercise, and provides an operational service in the Research and Development Center for Off shore Oil Safety and Environmental Technology. 展开更多

BACKGROUND: Timely reperfusion in ST-segment elevation myocardial infarction(STEMI)improves outcomes. System delay is that between first medical contact and reperfusion therapy,comprising prehospital and hospital components. This study aimed to characterize prehospital system delay in Singapore.METHODS: A retrospective chart review was performed for 462 consecutive STEMI patients presenting to a tertiary hospital from December 2006 to April 2008. Patients with cardiac arrest secondarily presented were excluded. For those who received emergency medical services(EMS),ambulance records were reviewed. Time intervals in the hospital were collected prospectively. The patients were divided into two equal groups of high/low prehospital system delay using visual binning technique.RESULTS: Of 462 patients, 76 received EMS and 52 of the 76 patients were analyzed. The median system delay was 125.5 minutes and the median prehospital system delay was 33.5minutes(interquartile range [IQR]=27.0, 42.0). Delay between call-received-by-ambulance and ambulance-dispatched was 2.48 minutes(IQR=1.47, 16.55); between ambulance-dispatch and arrival-at-patient-location was 8.07 minutes(IQR=1.30, 22.13); between arrival-at- and departurefrom-patient-location was 13.12 minutes(IQR=3.12, 32.2); and between leaving-patient-location to ED-registration was 9.90 minutes(IQR=1.62, 32.92). Comparing patients with prehospital system delay of less than 35.5 minutes versus more showed that the median delay between ambulancedispatch and arrival-at-patient-location was shorter(5.75 vs. 9.37 minutes, P<0.01). The median delay between arrival-at-patient-location and leaving-patient-location was also shorter(10.78 vs.14.37 minutes, P<0.01).CONCLUSION: Prehospital system delay in our patients was suboptimal. This is the first attempt at characterizing prehospital system delay in Singapore and forms the basis for improving efficiency of STEMI care. 展开更多
