Study on Cold Wave Weather in Hexi Corridor from March 12 to 14 in 2011

[ Objectivel The aim was to study the cold wave in Hexi Corridor in 2011 and to summarize report experience. [ Method] Routine obser- vation data and Ecmwf numerical product were used to analyze the circulation background, causes and influential system of Hexi Corridor from March 12 to 14 in 2011. [Result] The cold wave in the mid-high latitude circulation in Northern hemisphere transited from radial type to warp type. High early basic temperature was the premise of cold wave. Drastic ground movement was the direct cause of cold wave. Prevailing cold advection was one primary cause of temperature reduction. Radiation in sunny days also posed certain influences on regional temperature. Factors weakened the gale were as follow, cold air largely in north area, cold air moving southeastward in diffusion, front passing early, upper and lower air conver- gence against the convection development and slow wind in high and lower air. [ Conclusion] The study provided important references for further enhancement of cold wave and gale report.

Nurses'experiences in voluntary error reporting:An integrative literature review

Objective:This integrative review aimed to examine and understand nurses’experiences of voluntary error reporting(VER)and elucidate factors underlying their decision to engage in VER.Method:This is an integrative review based on Whittemore&Knafl five-stage framework.A systematic search guided by the PRISMA 2020 approach was performed on four electronic databases:CINAHL,Medline(PubMed),Scopus,and Embase.Peer-reviewed articles published in the English language from January 2010 to December 2020 were retrieved and screened for relevancy.Results:Totally 31 papers were included in this review following the quality appraisal.A constant comparative approach was used to synthesize findings of eligible studies to report nurses'experiences of VER represented by three major themes:nurses'beliefs,behavior,and sentiments towards VER;nurses'perceived enabling factors of VER and nurses'perceived inhibiting factors of VER.Findings of this review revealed that nurses’experiences of VER were less than ideal.Firstly,these negative experiences were accounted for by the interplays of factors that influenced their attitudes,perceptions,emotions,and practices.Additionally,their negative experiences were underpinned by a spectrum of system,administrative and organizational factors that focuses on attributing the error to human failure characterized by an unsupportive,blaming,and punitive approach to error management.Conclusion:Findings of this review add to the body of knowledge to inform on the areas of focus to guide nursing management perspectives to strengthen institutional efforts to improve nurses'recognition,reception,and contribution towards VER.It is recommended that nursing leaders prioritize and invest in strategies to enhance existing institutional error management approaches to establish a just and open patient safety culture that would promote positivity in nurses’overall experiences towards VER.

What factors influence patient experience in orthopedic oncology office visits?

BACKGROUND Patient satisfaction and reported outcomes are becoming increasingly important in determining the efficacy of clinical care.To date no study has evaluated the patient experience in the orthopedic oncology outpatient setting to determine which factors of the encounter are priorities to the patient.AIM To evaluate what factors impact patient experience and report satisfaction in an outpatient orthopedic oncology clinic.METHODS Press Ganey®patient surveys from a single outpatient orthopedic oncology clinic at a tertiary care setting were prospectively collected per routine medical care.All orthopedic oncology patients who were seen in clinic and received electronic survey were included.All survey responses were submitted within one month of clinic appointment.IRB approval was obtained to retrospectively collect survey responses from 2015 to 2016.Basic demographic data along with survey category responses were collected and statistically analyzed.RESULTS One hundred sixty-two patient surveys were collected.Average patient age was 54.4 years(SD=16.2 years)and were comprised of 51.2% female and 48.4%male.64.2%of patients were from in-state.Out of state residents were more likely to recommend both the practice and attending physician.The likelihood to recommend attending physician was positively associated with MD friendliness/courtesy(OR=14.4,95%CI:2.5-84.3),MD confidence(OR=48.2,95%CI:6.2-376.5),MD instructions follow-up care(OR=2.5,95%CI:0.4-17.4),and sensitivity to needs(OR=16.1,95%CI:1-262.5).Clinic operations performed well in the categories of courtesy of staff(76%)and cleanliness(75%)and less well in ease of getting on the phone(49%),information about delays(36%),and wait time(37%).CONCLUSION Orthopedic specialties can utilize information from this study to improve care from the patient perspective.Future studies may be directed at how to improve these areas of care which are most valued by the patient.

Experience in Acupuncture Treatment of Dizziness and Vertigo——A Report of 3 Cases

Dizziness and vertigo is a commonly encountered disease in clinic. There has been the saying from ancient times that "there would be no dizziness if without wind", " there would be no dizziness if without phlegm", "there would be no dizziness if without deficiency", and " there would be no dizziness if without fire". However, in the author's view, the dizziness and vertigo caused by blood stasis blocking the collaterals is most commonly seen in clinic, which should deserve more attention. The following is an introduction about the author's experience in treating 3 cases of dizziness and vertigo with acupuncture.

Twitter Sentiment at the Hospital and Patient Level as a Measure of Pediatric Patient Experience

Although pediatric cancer survival rates have improved, cancer is still the leading cause of death by disease among children in the United States. With nearly 16,000 new diagnoses each year of children having an average age of six years old, there is still much to be done to improve survival rates among children diagnosed with cancer. Additionally, clinical outcomes can be greatly improved by first understanding the patient perspective and, consequently, there is a need to understand the pediatric cancer patient experience. Interest in the analysis of patient-reported outcome (PRO) measures, including those specific to patient experience, has grown in recent years as attempts are made to understand and assess latent (i.e., unobserved) traits such as quality of life. While most traditional PRO measures involve lengthy and costly surveys that are limited in scope, posts on social media platforms are frequently lauded as more authentic, unbiased measures of patient experience. While many previous studies have utilized Twitter as a source for patient experience data that is not easily captured by traditional PROs, very few studies have examined the use of Twitter data to explore and better understand the experience of pediatric cancer patients specifically. Lexicon-based sentiment analysis of Twitter data was used both to examine the pediatric cancer patient experience as well as to compare the attitudes, perceptions, and overall impressions of individuals with St. Jude experiences to those with more general experiences. Results indicated that patients reflected on their care with more relative negativity when speaking of experiences other than St. Jude. While there were some notable differences between the two comparison groups, the sentiment of both was still mostly positive. Pediatric oncology differs greatly from adult oncological care and, thus, the proposed use of sentiment analysis with patient social media posts serving as authentic PRO data likely differentiates more between medical providers and clinical care settings when assessing adult patient experience. Despite limitations, this exploratory study suggests that Twitter can be utilized as a source for authentic, real-time patient experience data that will improve overall care and better clinical outcomes, even among the pediatric cancer patient population.

数字化实验报告在兽医学科教学改革中的应用与实践

实验教学是兽医学科教学体系中的核心环节,而实验报告是学生掌握实验原理、分析实验现象和撰写实验结果的重要载体,是实验教学中不可或缺的组成部分。目前,兽医学科实验教学过程中纸质版实验报告作为实验课程的主要考核模式,存在对动态试验过程无法再现、文字无法客观真实描述实验现象等问题,传统的纸质版实验报告已经无法满足当下高校培养学生的教学需要。在兽医学科实验教学过程中,多数动物实验现象用文字无法进行恰当的描述,以图片、视频、动画等数字化方式可以更加直观的展现动物疾病发病前后器官病理变化,利于学生通过撰写实验报告加深实验技能与专业知识。在此基础上提出了数字化实验报告的教学模式并在实际教学实践中进行推广应用。通过实行数字化实验报告,学生实验教学课堂反应效果好,教学质量提升明显,特总结此文,以期为改善实验教学手段,提升教学质量提供参考。
