However, China lacks such studies extremely, which cannot meet the requirement of rapid decision-support system. This study aims to realize modeling EMS-MCIs in Shanghai, to improve mass casualty incident (MCI) rescue efficiency in China, and to provide a possible method of making rapid rescue decisions during MCIs.Methods: This study established a system dynamics (SD) model of EMS-MCIs using the Vensim DSS program. Intervention scenarios were designed as adjusting scales of MCIs, allocation of ambulances, allocation of emergency medical staff, and efficiency of organization and command.Results: Mortality increased with the increasing scale of MCIs, medical rescue capability of hospitals was relatively good, but the efficiency of organization and command was poor, and the prehospital time was too long. Mortality declined significantly when increasing ambulances and improving the efficiency of organization and command; triage and on-site first-aid time were shortened if increasing the availability of emergency medical staff. The effect was the most evident when 2,000 people were involved in MCIs; however, the influence was very small under the scale of 5,000 people.Conclusion: The keys to decrease the mortality of MCIs were shortening the prehospital time and improving the efficiency of organization and command. For small-scale MCIs, improving the utilization rate of health resources was important in decreasing the mortality. For large-scale MCIs, increasing the number of ambulances and emergency medical professionals was the core to decrease prehospital time and mortality. For super-large-scale MCIs, increasing health resources was the premise. Keywords: system dynamics model, emergency medical system, mass casualty incidents

Research concerning the impact of earthquake victims' individual behavior and its association with earthquake-related injuries is lacking. This study examined this relationship along with effectiveness of earthquake rescue measures. The six most severely destroyed townships during the Lushan earthquake were examined; 28 villages and three earthquake victims' settlement camp areas were selected as research areas. Inclusion criteria comprised living in Lushan county for a longtime, living in Lushan county during the 2013 Lushan earthquake, and having one's home destroyed. Earthquake victims with an intellectual disability or communication problems were excluded. The earthquake victims (N (number) = 5165, male = 2396) completed a questionnaire (response rate: 94.7%). Among them, 209 were injured (5.61%). Teachers (p < 0.0001, OR (odds ratios) = 3.33) and medical staff (p = 0.001, OR = 4.35) were more vulnerable to the earthquake than were farmers. Individual behavior was directly related to injuries, such as the first reaction after earthquake and fear. There is an obvious connection between earthquake-related injury and individual behavior characteristics. It is strongly suggested that victims receive mental health support from medical practitioners and the government to minimize negative effects. The initial reaction after an earthquake also played a vital role in victims' trauma; therefore, earthquake-related experience and education may prevent injuries. Self-aid and mutual help played key roles in emergency, medical rescue efforts.

Wenya Yu,1,* Meina Li,1,* Chen Xue,1,* Jingrui Wang,1 Jiazhen Liu,2 Haiping Chen,1 Lulu Zhang1 1Institute of Military Health Management, Second Military Medical University, 2Shanghai Sixth People's Hospital, Shanghai, People's Republic of China *These authors contributed equally to this work Objective: Most patients in the People's Republic of China prefer tertiary hospitals when seeking medical services. The aim of this study was to assess outpatient satisfaction with tertiary hospitals in the People's Republic of China, test overall and subscale satisfaction, and explore whether sociodemographic characteristics lead to different degrees of satisfaction and whether subscale outpatient satisfaction contributes to overall satisfaction.Methods: A closed questionnaire was given out to investigate outpatients' sociodemographic characteristics, overall satisfaction, and various subtypes of satisfaction, and a 5-point Likert scale was employed to measure the degree of outpatient satisfaction. Descriptive analysis, Kruskal–Wallis test, Spearman's rank correlation coefficient, and logistic regression analysis were employed for statistical analysis.Results: Response rate was 92.48% (971/1,050). Outpatients' sociodemographic characteristics (including sex, age, occupation, monthly income, residence, and marital status) were related to various subtypes of satisfaction to varying degrees. Outpatients who were male, older, married, with low or middle incomes, living in Shanghai or other areas of the People's Republic of China, medical staff, or students were more satisfied with various subtypes of satisfaction than those without these characteristics. In further analyses, satisfaction with their medical needs being met by doctors had the strongest relation to overall satisfaction, followed by satisfaction with doctors' service attitudes, medical costs, waiting time, prescription, and diagnosis and treatment time. Satisfaction with environment had the weakest contribution to overall satisfaction.Conclusion: This study gave some suggestions for tertiary hospitals in advanced areas of the People's Republic of China. Outpatient sociodemographic characteristics should be paid more attention by medical staff to improve the degree of satisfaction. Tertiary hospitals in the People's Republic of China should provide more support on the management of doctors, medical costs, and time.

The aim of this paper is to investigate medical efforts and injury profiles of victims of the Lushan earthquake admitted to three military hospitals. This study retrospectively investigated the clinical records of 266 admitted patients evacuated from the Lushan earthquake area. The 2005 version of the Abbreviated Injury Scale (AIS-2005) was used to identify the severity of each injury. Patient demographic data, complaints, diagnoses, injury types, prognosis, means of transportation, and cause of injury were all reviewed individually. The statistical analysis of the study was conducted primarily using descriptive statistics. Of the 266 patients, 213 (80.1%) were admitted in the first two days. A total of 521 injury diagnoses were recorded in 266 patients. Earthquake-related injuries were primarily caused by buildings collapsing (38.4%) and victims being struck by objects (33.8%); the most frequently injured anatomic sites were the lower extremities and pelvis (34.2%) and surface area of the body (17.9%). Fracture (41.5%) was the most frequent injury, followed by soft tissue injury (27.5%), but crush syndrome was relatively low (1.2%) due to the special housing structures in the Lushan area. The most commonly used procedure was suture and dressings (33.7%), followed by open reduction and internal fixation (21.9%).The results of this study help formulate recommendations to improve future disaster relief and emergency planning in remote, isolated, and rural regions of developing countries.

AbstractThe nexus concept has considerably matured during the past decade. Numerous literature reviews have significantly contributed to taking stock of the advancements in knowledge and tool development to improve science-policy support on highly connected and interdependent resources. However, literature reviews often focus on specific sector-based nexus concepts (such as water-energy-food nexus) and analyses (such as environmental assessment, technical tools, or the management and policy dimension). Therefore, a comprehensive understanding of the actual nexus and the resources it builds upon still needs to be improved. This paper aims to test the validity of the nexus construct for research and practice. Based on a systematic review of reviews, including 62 nexus-related review papers and subsequent consultation of some sixty nexus experts, we suggest a robust but flexible approach to advancing the Resource Nexus for research and practice. In doing so, the knowledge provided by nexus research may provide more substantial support to decision-makers when designing and implementing policies for the sustainable management of environmental resources.

Haiping Chen,1 Meina Li,1 Jingrui Wang,1 Chen Xue,1 Tao Ding,1 Xin Nong,2 Yuan Liu,1 Lulu Zhang11Department of Military Health Management, College of Health Service, Second Military Medical University, Shanghai, 2Department of Medical Research, Rizhao Maternity and Infant Hospital, Shandong, People's Republic of ChinaObjective: The aim of this study was to observe the current status of inpatient satisfaction and analyze the possible factors influencing patient satisfaction during hospitalization.Methods: A cross-sectional investigation was conducted to obtain basic information about inpatient satisfaction, and statistical methods were used to describe and analyze the data. A total of 878 questionnaires were included in this study. A 5-point Likert scale rating was employed to assess items related to hospitalization care. Nonparametric tests and ordinal logistic analysis were used to explore the relationship between predictors and the patients' overall satisfaction.Results: Among the respondents, 89.75% were satisfied overall with the service they received during hospitalization, while 0.57% reported dissatisfaction. Inpatient demographic characteristics such as sex of the patients, occupation, age, and residence had significant associations with satisfaction, while monthly income and marital status did not. Additionally, the statistical outcome indicated that doctors' and nurses' service attitudes, and expenditure and environment were found to have an impact on the inpatient satisfaction ratings, with odds ratio of 2.43, 3.19, and 2.72, respectively.Conclusion: This study emphasizes the influence of sex of the patients, the service attitudes of the doctors and nurses, and expenditure and environment on inpatient satisfaction. An increase in satisfaction ratings concerning the areas of doctors' and nurses' service attitudes, and expenditure and environment can improve the overall satisfaction levels. Responsible health management departments should pay attention to patient satisfaction and improve the quality of relevant health services, thus ultimately enhancing inpatients' hospitalization experiences.Keywords: inpatients' satisfaction, hospitalization service, influencing factors

The purpose of this study was to build a healthcare quality assessment system with disease category as the basic unit of assessment based on the principles of case classification, and to assess the quality of care in a large hospital in Shanghai. Using the Delphi method, four quality indicators were selected. The data of 124,125 patients discharged from a large general hospital in Shanghai, from October 1, 2004 to September 30, 2007, were used to establish quality indicators estimates for each disease. The data of 51,760 discharged patients from October 1, 2007 to September 30, 2008 were used as the testing sample, and the standard scores of each quality indicator for each clinical department were calculated. Then the total score of various clinical departments in the hospital was calculated based on the differences between the practical scores and the standard. Based on quality assessment scores, we found that the quality of healthcare in departments of thyroid and mammary gland surgery, obstetrics and gynaecology, stomatology, dermatology, and paediatrics was better than in other departments. Implementation of the case classification for healthcare quality assessment permitted the comparison of quality among different healthcare departments.

Particulate matter (PM) was collected in three different areas, SY-1, SY-2, and SY-3, in Shenyang, China, during the warm and cold seasons from 2012 to 2014. SY-1 was located beside a thermal power plant, far from the central area. SY-2 was near a coal heating boiler on the main road, close to the central area. SY-3 was on the main road, without fixed emission sources. Nine PM-bound polycyclic aromatic hydrocarbons (PAHs) were analyzed. The results showed that the mean concentration of total PAHs was higher in the cold season (92.6–316 ng m(−3)) than in the warm season (18.4–32.2 ng m(−3)). Five- and six-ring PAHs occupied a large percentage at all sites in the warm season, and four-ring PAHs were the dominant components in the cold season. Several diagnostic PAH ratios indicated that the main sources of PAHs in Shenyang in the warm and cold seasons were not only coal burning but also vehicle emission. In this study, we suggest that a benzo[a]pyrene/benzo[ghi]perylene ratio ([BaP]/[BgPe]) of 0.6 was a useful indicator to speculate the relative significance of coal burning and vehicle exhaust. Although the Shenyang government has undertaken actions to address air pollution, the PM and PAH concentrations did not decrease significantly compared to those in our previous studies. The cancer risk calculated from the BaP equivalent total concentration at all three sites in the warm and cold seasons exceeded the acceptable limit established by the US EPA.
