BACKGROUND:Point-of-care ultrasound(POCUS)has become increasingly integrated into the practice of emergency medicine.A common application is the extended focused assessment with sonography in trauma(eFAST)exam.The American College of Emergency Physicians has guidelines regarding the scope of ultrasound in the emergency department and the appropriate documentation.The objective of this study was to conduct a review of performed,documented and billed eFAST ultrasounds on trauma activation patients.METHODS:This was a retrospective review of all trauma activation patients during a 10-month period at an academic level-one trauma center.A list comparing all trauma activations was crossreferenced with a list of all billed eFAST scans.Medical records were reviewed to determine whether an eFAST was indicated,performed,and appropriately documented.RESULTS:We found that 1,507 of 1,597 trauma patients had indications for eFAST,but 396(27%)of these patients did not have a billed eFAST.Of these 396 patients,87(22%)had documentation in the provider note that an eFAST was performed but there was no separate procedure note.The remaining 309(78%)did not have any documentation of the eFAST in the patient’s chart although an eFAST was recorded and reviewed during ultrasound quality assurance.CONCLUSION:A significant proportion of trauma patients had eFAST exams performed but were not documented or billed.Lack of documentation was multifactorial.Emergency ultrasound programs require appropriate reimbursement to support training,credentialing,equipment,quality assurance,and device maintenance.Our study demonstrates a significant absence of adequate documentation leading to potential revenue loss for an emergency ultrasound program. 展开更多

Longevity in most cases brings down poorer health as well as functional status. Thus, it is necessary to understand the problems as well as social, psychological, and medical needs of elderly people in order to plan their optimal care. Objectives: To assess the mental health status (depression and memory state) of elderly people attending Geriatric clinic in medical city, and to determine the influence of some sociodemographic factors on elderly mental health status. Subjects and Method: A cross-sectional study was conducted among elderly people aged 60 years and more who attended geriatric clinic of medical city in Baghdad, from 1st of April to the end of June 2015. Special questionnaire form had been used for data collection via direct interview. The evaluation of the mental state was performed by using modified version of Wechsler Memory Scale and geriatric depression scale. Results: A total of 400 elderly persons were enrolled in the study, 109 (27.3%) of them had impaired memory. The analysis of data revealed that the age and marital status had statistical significant association with memory state. Nearly three quarter (72.8%) of study group had depression according to geriatric depression scale. The majority of studied women had depression (90%), and the same percentage was observed among widowed elders joining in the study. 展开更多

Purpose: The purpose of this review was to discuss the status of evidence related to the assessment of readiness of healthcare facilities for e-health initiatives implementation, specifically the common Electronic Health Record (EHR) systems. Methods: An integrative review approach was utilized. The databases of Google Scholar, Scopus, Science Direct, PubMed, Medline, CINAHL, Ovid, ProQuest, and EBSCO host were searched for related evidence published between 2000 and 2018. Results: Seventeen studies were included in the current review. In terms of methodological approach, the included studies were 7 correlational studies, 5 review papers, 4 qualitative papers, and one mixed methods study. At the current integrative review, the themes of complex healthcare change, and the main theme of e-health readiness assessment were identified. Conclusion: Assessing and reporting the levels of readiness for EHRs implementation are highly recommended as it has a high impact on the critically-needed adoption and usage of the implemented system. Selecting the right tool for the right audience to address readiness is essential in the assessment process which is recommended to be conducted early at the road map of the project implementation. Future research is recommended to address readiness for e-health initiatives at the different settings and different target populations including communities where the healthcare facilities functions and service receivers’ readiness. 展开更多

The knowledge about factors contributing to remission among individuals with schizophrenia is still missing. Studies show that the number of individuals’ reaching remission is varying among psychiatric outpatient care centres. Therefore, the purpose was to investigate case managers (CM) perception of care interventions promoting remission. Semi-structured interviews were conducted with CM (n = 12) and data were analysed with qualitative content analysis. The results show that CM needs to possess competence, master assessment structure and process. These key-points appear to be of crucial importance for a successful promotion of remission among individuals with schizophrenia. 展开更多

The study was carried out exclusively in Ghana to explore the approaches employed by consultants in risk assessment at the design phase of projects in Ghana. One hundred and fourteen (114) consultants were selected out of a population of one hundred and eighty six (186) from three main professional associations in Ghana made up of the Ghana Institute of Architects, Ghana Institution of Engineers and the Ghana Institution of Surveyors (Quantity Surveying Division) practicing in Ghana for the study. Both primary and secondary data were collected. A descriptive survey was also used to observe and describe the presence, frequency or absence of characteristics of a phenomenon as it naturally occurred, in order to gain additional information. A questionnaire was also designed to collect data from the architects, engineers and quantity surveyors. The data was analyzed using Statistical Package for the Social Scientists (SPSS) 17.0. Descriptive and inferential statistics, such as frequency tables, percentages and cross tabulations were used in the data analysis and summaries. Simple tests of associations were undertaken by using Chi square and Cramer’s V statistics to compare relationships between variables. Again, relative importance index was also used to analyze some of the data by computing to deduce their rankings. The relative importance index was used to analyze some of the data by computing to deduce their rankings. The research revealed that majority of consultants had an average knowledge of risk management. Based on the findings it was recommended that consultants undergo advanced training in risk assessment. It was therefore suggested that consultancy firms should develop a set of laid down procedures for consultants to use in risk assessment in order that the use of intuition employed by majority is lessened. The challenges observed in risk assessment and the remedial steps suggested curtailing the detrimental effects of risks would be of wide importance to many developing economies. 展开更多

This work addresses the integrated assessment of rockfall(including landslides) hazards and risk for S301, Z120, and Z128 highways, which are important transportation corridors to the world heritage site Jiuzhai Valley National Park in Sichuan, China. The highways are severely threatened by rockfalls or landslide events after the 2017 Ms 7.0 Jiuzhaigou earthquake. Field survey(September 14-18 th, 2017, May 15-20 th, 2018, and September 9-17 th, 2018), unmanned aerial vehicle(UAV), and satellite image identified high-relief rockfalls and road construction rockfalls or landslides along the highway. Rockfall hazard is qualitatively evaluated using block count, velocity, and flying height through a 3D rockfall simulation at local and regional scales. Rockfall risk is quantitatively assessed with rockfall event probability, propagation probability, spatial probability, and vulnerability for different block volume classes. Approximately 21.5%, 20.5%, and 5.3% of the road mileage was found to be subject to an unacceptable(UA) risk class for vehicles along S301, Z120, and Z128 highways, respectively. Approximately 20.1% and 3.3% of the road mileage belong to the UA risk class for tourists along Z120 and Z128 highways, respectively. Results highlighted that high-relief rockfall events were intensively located at K50 to K55(Guanmenzi to Ganheba) and K70 to K72(Jiudaoguai to Shangsizhai Village) road mileages along S301 highway and KZ18 to KZ22(Five Flower Lake to Arrow Bamboo Lake) road mileages, KZ30(Swan Lake to Virgin Forests), and KY10.5 kilometers in Jiuzhai Valley. Rockfalls in these locations were classified under the UA risk class and medium to very high hazard index. Road construction rockfalls were located at K67(Jiuzhai Paradise) and K75–K76 kilometers along S301 highway and KZ12 to KZ14(Rhino Lake to Nuorilang Waterfall), KZ16.5 to KZ17.5(Golden Bell Lake), KY5(Lower Seasonal Lake), and KY14(Upper Seasonal Lake) kilometers along Z120 and Z128 highway in Jiuzhai Valley.

The results of long-term author’s scientific research in the field of geological and geographical study and landscape mapping of large regional links, such as Sikhote-Alinsky, Sakhalinsky, Kamchatsky, Anadyrsky, located in the Pacific landscape belt of Russia, are considered (Starozhilov, 2013). The studies were conducted at the medium scale (1:500,000) and were accompanied by landscape mapping (Starozhilov, 2016). The proposed article discusses the theory and practice of the overall results and the strategic vision of applying the landscape approach with selected examples. The wide range of possibilities of applying the landscape approach in studying the interaction of nature and society is emphasized. The importance and the indisputable need for the synthesis, analysis and assessment of natural systems based on the mapping of landscape geosystems to assess the environmental management of not only regional territories, but also of Pacific Russia as a whole are noted. 展开更多

Background:Patients with ST-segment elevation myocardial infarction(STEMI)who present without typical chest pain are associated with a poor outcome.However,whether angiographic characteristics are related to a higher risk of mortality in this population is unclear.This study aimed to investigate whether the higher mortality risk in patients with STEMI without chest pain could be explained by their"high-risk"angiographic characteristics.Methods:We used data of 12,145 patients with STEMI who was registered in China Acute Myocardial Infarction registry from January 2013 to September 2014.We compared the infarct-related artery(IRA),thrombolysis in myocardial infarction(TIMI)flow grade in the IRA,and other angiographic characteristics between patients without and those with chest pain.Multivariable logistic regression model was used to identify independent risk factor of in-hospital mortality.Results:The 2922(24.1%)patients with STEMI presented without typical chest pain.These patients had a higher TIMI flow grade(mean TIMI flow grade:1.00 vs.0.94,P=0.02)and a lower rate of IRA disease of the left anterior descending artery(44.6%vs.51.2%,χ^2=35.63,P<0.01)than did those with typical chest pain.Patients without chest pain were older,more likely to have diabetes,longer time to hospital and higher Killip classification,and less likely to receive optimal medication treatment and primary percutaneous coronary intervention and higher In-hospital mortality(3.3%vs.2.2%,χ^2=10.57,P<0.01).After adjusting for multi-variables,presentation without chest pain was still an independent predictor of in-hospital death among patients with STEMI(adjusted odds ratio:1.36,95%confidence interval:1.02–1.83).Conclusions:Presentation without chest pain is common and associated with a higher in-hospital mortality risk in patients with acute myocardial infarction.Our results indicate that their poor prognosis is associated with baseline patient characteristics and delayed treatment,but not angiographic lesion characteristics.Clinical trial re 展开更多

Concentration of heavy metals from surface and groundwater within the communities were determined in order to assess the health risks linked to the use/consumption of same. Furthermore, the cancer risk for adults in surface water revealed medium to high cancer risk for arsenic (As);low to medium cancer risk for cadmium (Cd) and very high cancer risk for chromium (Cr). In addition, the cancer risk for adults in groundwater is as follows: high cancer risk for As;low cancer risk for Cd and very high cancer risk for Cr while that for children is very high cancer risk for As and Cr and then low cancer risk for Cd. The findings from this research confirm that the inhabitants within the study area are at direct health risk (carcinogenic and non-carcinogenic) due to the alternate use of surface and groundwater without any form of treatment. 展开更多

Turkana South Sub-County falls in the arid and semi-arid lands of Kenya, which are characterized temperatures of 20&deg;C to 41&deg;C with an average of 30.5&deg;C and precipitation in the range of 52 mm to 480 mm per year. The area has limited availability of water resources. The area has a land surface of 18,000 km2 and lies between Longitudes 35&deg;10'00" and 36&deg;45'00" East and between Latitudes 1&deg;0'00" and 3&deg;0'00" North. The study area faces immense difficulties in trying to meet its water requirements for her rapidly increasing populace, livestock needs and other developmental programmes. Surface water in the area is becoming unobtainable, thus the choice of groundwater exploitation. Indeed with the snowballing demand necessitated by energy, agricultural and livestock production needs in this area, there is an appeal into investigation for groundwater in this greatly remote and extensive area. Thus, the success in the exploration, development and management of groundwater in such a large area calls for such methods that can easily be used to zero down to exploitable targets. Given the expansiveness of the study area, remote sensing (RS) has been used to map lineaments which in turn have been used to deduce faulting affecting the geology of the area. The mapping by RS helped in identifying weathered zones, the fracture systems and fault zones sign of deeper weathered zones which are interpreted to be potential areas since mainly water is stored within fractures and the weathered zones in subterranean and in hard rocks. In the field topographic expressions of faults and fractures which include;joints, fractures, scarps, river channels and slope breaks were mapped and it was observed that there was a comparison of the features to the coincidence raster and aspect interpreted lineaments. The earmarked points were later investigated using vertical electrical sounding (VES) to establish their feasibility for groundwater availability and extraction.

In China, decision-making meteorological services provide meteorological information for the production organization, disaster prevention and mitigation by the CPC committee, government, military leaders and decision-making departments at all levels, as well as scientific decision-making in the areas of rational development and utilization of climate resources and environmental protection. In order to understand the user’s satisfaction with the decision-making meteorological service, the Shaanxi Provincial Meteorological Bureau conducted a statistical survey, and the results showed that: 1) In 2017, the satisfaction level of provincial-level decision-making meteorological services in Shaanxi, China was 92.77%. Among them, the satisfaction index of “Ministry Department Service Personnel Professional Image and Service Awareness” was 94.12%, and the “Weather Forecast Warning Accuracy” satisfaction index was 90.18%. 2) Decision-making users have become an important channel for obtaining meteorological information through meteorological websites, televisions, mobile phone text messages, APP mobile applications, broadcasting, and Meteorological Information Express. Rainstorms, floods, high temperature heat, cold winds, hail, precipitation, and lightning are still the main concerns of decision-makers. 3) The focus on haze and UV intensity is 15% and 8% higher than that of 2016. The next 1 - 3 days weather forecast and 0 - 6 hours short-term forecast are still the most valuable forecast products for decision-making users. Compared with 2016, the next 1 - 3 days weather forecast, future 0 - 6 hours forecast, traffic meteorology, precipitation probability, and air quality forecast increase by 1% to 14% in the year of 2017. 展开更多
