Impact of Laboratory Value Flowsheet in Electronic Health Record (EHR) Documentation Time

Research on the use of EHR is contradictory since it presents contradicting results regarding the time spent documenting. There is research that supports the use of electronic records as a tool to speed documentation;and research that found that it is time consuming. The purpose of this quantitative retrospective before-after project was to measure the impact of using the laboratory value flowsheet within the EHR on documentation time. The research question was: “Does the use of a laboratory value flowsheet in the EHR impact documentation time by primary care providers (PCPs)?” The theoretical framework utilized in this project was the Donabedian Model. The population in this research was the two PCPs in a small primary care clinic in the northwest of Puerto Rico. The sample was composed of all the encounters during the months of October 2019 and December 2019. The data was obtained through data mining and analyzed using SPSS 27. The evaluative outcome of this project is that there is a decrease in documentation time after implementation of the use of the laboratory value flowsheet in the EHR. However, patients per day increase therefore having an impact on the number of patients seen per day/week/month. The implications for clinical practice include the use of templates to improve workflow and documentation as well as decreasing documentation time while also increasing the number of patients seen per day. .

Study on the development and usage of a cardiopulmonary resuscitation time point recorder

BACKGROUND: To invent a novel cardiopulmonary resuscitation(CPR) time point recorder to synchronously and automatically record the time and to identify its effectiveness in humans.METHODS: A CPR time point recorder was invented after the doctors were familiar with the traditional Utstein recovery registration mode and mastered the registration time points required. The progress of CPR was simulated. The standard and correct times were recorded, and the doctors performing the recovery collected the data about the times using our CPR time point recorder or the memory registration mode.RESULTS: The deviation times were 21.4±24.7 seconds for the memory group and 3.57±4.58 seconds for CPR time point recorder group. The deviation of times increased signifi cantly depending on the increase of the operation items in the memory group. A similar phenomenon was found in the timer group but with a smaller difference(P<0.01).CONCLUSION: A CPR time point recorder could reduce the deviation of operate-time, especially after a long-time operation, and for procedures with more operating items, compared with the memory mode. It was a more advantageous and accurate method for the Utstein registration.

Effectiveness and time-course adaptation of resistance training vs. plyometric training in prepubertal soccer players

Purpose:This study aimed to assess the effectiveness and time course for improvements in explosive actions through resistance training(RT)vs.plyometric training(PT)in prepubertal soccer players.Methods:Thirty-four male subjects were assigned to:a control group(n=11);an RT group(5 regular soccer training sessions per week,n=12);a PT group(3 soccer training sessions and 2 RT sessions per week,n=11).The outcome measures included tests for the assessment of muscle strength(e.g.,1 repetition maximum half-squat test),jump ability(e.g.,countermovement jump,squat jump,standing long jump,and multiple 5 bounds test),linear speed(e.g.,20m sprint test),and change of direction(e.g.,Illinois change of direction test).Results:The RTG showed an improvement in the half-squat(△=13.2%;d=1.3,p<0.001)and countermovement jump(△=9.4%;d=2.4,p<0.001)at Week 4,whereas improvements in the 20-m sprint(△=4.2%;d=1.1,p<0.01);change of direction(CoD)(△=3.8%;d=2.1,p<0.01);multiple 5 bounds(△=5.1%;d=1.5,p<0.05);standing long jump(△=7.2%;d=1.2,p<0.01);squat jump(△=19.6%;d=1.5,p<0.01);were evident at Week 8.The PTG showed improvements in CoD(△=2.1%;d=1.3,p<0.05);standing long jump(△=9.3%;d=1.1,p<0.01);countermovement jump(△=16.1%;d=1.2,p<0.01);and squat jump(△=16.7%;d=1.4,p<0.01);at Week 8 whereas improvements in the 20-m sprint(△=4.1%;d=1.3,p<0.01);and multiple 5 bounds(△=7.4%;d=2.4,p<0.001);were evident only after Week.The RT and PT groups showed improvements in all sprint,CoD,and jump tests(p<0.05)and in half-squat performance,for which improvement was only shown within the RTG(p<0.001).Conclusion:RT and PT conducted in combination with regular soccer training are safe and feasible interventions for prepubertal soccer players.In addition,these interventions were shown to be effective training tools to improve explosive actions with different time courses of improvements,which manifested earlier in the RTG than in the PTG.These outcomes may help coaches and fitness trainers set out clear and concise goals of training according to the specific time course of improvement difference between RT and PT on proxies of athletic performance of prepubertal soccer players.

The Localization, Practice and Innovation of Time Banking——On a New Approach to China's Aging Population

In the context of an aging population, the promotion of time banking as a new model of voluntary service can help alleviate the ever–increasing pressures for elderly care and services in China. The development of time banking in China has successively undergone the stage of traditional practice, the stage of infancy and exploration, as well as the stage of accelerated growth. Meanwhile, this process has also witnessed the formation of many localized innovations. To further the localization and innovation of time banking, this paper analyzes its basis in traditional culture, summarizes its process of practice and explores new directions of future innovation. Based on the summary of existing problems, this paper proposes to enhance the recognition of time banking among the public, facilitate localized innovation of time banking, promote its informatization, and involve the participation of young people, particularly college students.

The impact of a computerized care records service (CRS) on doctors’ work patterns in urological outpatient clinics

Objective: Government targets to reduce waiting times are putting enormous pressures on outpatient services. The implementation of an electronic care records service (CRS) at our hospital in 2008 has led to widespread press coverage of ensuing chaos in clinical administration. We wanted to know how this new electronic system impacted on our working patterns in outpatient clinics and – more specifically – on the time actually spent with the patients. Material & methods: This study was performed 4 and 12 months after implementation of CRS to assess its impact on the time distribution in clinic. Senior doctors were monitored with a stop clock during consultations. Timings for pre- and post-consultation administration, and the actual consultation with the patient were recorded. A total of 170 consultations were evaluated in this way. Results: The key findings were that the total time needed to spend on a urological outpatient of 16 minutes remains unchanged from the pre-CRS era, but a majority (57%) of this time is spent in administration on the computer without the patient involved. Conclusion: No more than 15 patients should be seen in a 4 hour outpatient clinic per doctor. This recommendation drawn up by BAUS before CRS remains still valid. Patient administration related to the consultation that has previously been done by administrative aides is now to be done by the doctors on the computer in the same consultation session. Intended to streamline patient pathways, this does reduce the quality interaction-time between doctor and patients significantly.

The Effect of Hamstring Stretching on Muscle Hardness and Isokinetic Muscle Performance

The purpose of this study was to clarify the effects and the time course of moderate hamstring stretching on the hardness and strength of the knee flexor muscles. Thirteen young adults performed static stretching of their hamstrings （2 minx 3 repetitions）. Before and after the static stretching, muscle hardness and concentric isokinetic torque of the knee flexors （180~/s） was determined. The hardness of the long head of the BF （biceps femoris） muscle was measured by using shear wave ultrasound elastography images. To follow the time course of the stretching effects, we determined the above parameters before, immediately after, and every 10 min for torque and every 5 min for muscle hardness until 30 min after stretching. Muscle hardness of the BF significantly decreased when compared with before the stretching （P 〈 0.001）, and remained significantly reduced until 25 min. However, the knee flexion torque did not show any change at any timing. As seen in this experiment, moderate stretching decreased the muscle hardness of the BF without a decline in the knee flexion torque. Thus, these findings suggest that moderate stretching is useful as a warm-up maneuver.

晚间授课会导致大学生课程成绩的“无谓损失”吗?

课程成绩是学生学习和个人发展的重要风向标。优化课堂教学安排减少课程成绩无谓损失是目前高校教务部门关注的热点问题。本文从排课时间视角实证讨论了课堂教学安排对大学生课程成绩的影响。研究表明:(1)晚上进行课堂教学会导致学生课程成绩下降。(2)对于同一教学班而言,所有课堂教学均在晚上进行,将带来严重的课程成绩损失。(3)晚上进行必修课程教学和采用多位教师协同教学能够缓释晚上教学带来的课程成绩损失。据此,为缓释晚上教学带来的课程成绩损失,应当深入推进教学范式改革,尽量避免晚上教学;完善教学安排系统,妥善考虑课程性质差异;推动课程组深度教学合作,施行同课师资交叉授课。

高速铁路旅客购票时间选择行为研究

研究高速铁路旅客的购票行为对铁路企业预测需求、优化票价、分配票额等具有重要意义。考虑旅客个体和群体层面的异质性,分别构建混合和潜在类别Logit模型,研究出行时段、票种和供需关系等因素对旅客购票时间选择的影响。利用售票数据估计模型参数,得到高速铁路旅客购票时间选择的规律:一天中下午和晚上出行的旅客在出行当日或前一天购票的可能性更高;购买全价票、儿童票、半价票的旅客偏向于在距离出发日9~30 d内购票,免票旅客往往选择随到随走;供需关系会显著影响旅客的购票时间选择而且越临近出发日影响越显著。进一步结合预售期购票量预测值和旅客购票选择概率,计算各预售阶段的购票量,可为铁路企业制定票额预分和浮动票价等策略提供决策依据。

论何休日月时例中的详与略

《公羊》学者何休从详与略的角度对《春秋》的日月时例作了大量的阐发。何休基于二元对立的思维,对日、月、时这三个要素作两两对待,即日、月相对,日为详,月为略;月、时相对,月为详,时为略。何休从日月时的详略轻重出发,阐发蕴含其中的褒贬大义,但何休并没有采取二元对立的思维来阐明褒贬,即并不是详书日月以示褒,略书就意味着贬;其实有很多情况,日月时的详略表明的是褒、贬程度的浅深。也正因为日月时的详略在意义的阐发上具有程度上的深浅轻重等的变化关系,因此能很好地与其三世进化说相结合,从而具有王道进化的意义。而随着三世的演进,王道的逐渐实现,日月时的详略轻重的差异渐趋消弥,从而完成了它的王道进化的使命。

雷电冲击下土体应力及弹塑性界面时程分析

雷电作为自然界一种极端天气的表现形式,常给地基、地面、高耸建筑等造成严重破坏。工程防雷措施依赖于土体雷电冲击特性。现阶段,研究人员大多从电气工程角度探究雷电冲击土体造成的危害,但因学科间的差异与局限,雷电作用下岩土工程与电气工程的交叉融合方面的研究十分欠缺。本文构建土体雷电冲击模型,基于电弧通道能量平衡方程计算雷电放电产生的冲击波压力,将冲击波压力作为外加荷载作用在土体中,并通过修正Mohr-Coulomb屈服准则考虑动荷载下土体应变硬化,利用土体的理想锁定状态方程(Idealized Locked Equation of State)和动态扩孔方法考虑冲击波非稳态加载,探究雷电冲击下土体的弹塑性界面及应力时程变化规律。研究表明:在雷电冲击下,土体应力随时间变化呈现先陡增后迅速衰减的趋势,应力突变点表明土体此时正处于弹塑性交界面;在应力突变点之前,土体附加应力趋于0,处于弹性状态。任一时刻下,随着逐渐远离雷电冲击点,土体应力呈现迅速衰减的趋势,应力发生突变骤降表明此处土体正处于弹塑性交界面;在突变点之后土体附加应力趋于0,处于弹性状态。土体压缩系数对土体的弹塑性界面变化具有显著影响,随着压缩指标增大,土体塑性区半径逐渐减小;随着土体黏聚力逐渐增大,土体塑性区半径逐渐减小;增大土体弹性模量可以增大土体塑性区半径,但变化幅度相对较小;电流波形对土体塑性区中的应力会产生较大影响,而对土体弹性区影响较小。

变迁时代的生命历程、人生转折与心理嬗变——“知青”一代社会学家的口述史与集体叙事

改革开放40年来,中国社会发生了朝向现代化的迅猛变迁。在经济与社会结构急剧变化并取得有目共睹的成就的同时,中国人的价值观和社会行为模式也发生了明显的嬗变。1979年中国社会学重建后,作为对社会变迁及其影响最为敏感的群体,知青一代社会学人,因其个体生命史与改革开放同构及与社会学重建同步,成为表征转型时代心理蜕变的合适案例。就个体心理蜕变的向度说,转型或变迁影响到他们的认知方式、情感世界和个体行为的现代性;而就集体心态建构的向度说,他们在40年的职业生涯中,围绕中国式现代化与富民实践、遂生乐业的心态秩序、社会学本土化或中国化等议题所形成的话语叙事,都充分体现了这个独特群体在大变革时代的集体心态。进一步,在个体心理蜕变和集体心态建构之间,存在着多种重叠与共通的部分,它使得知青社会学人在变革时代的心理嬗变就是一部个体心理与集体心态互为镶嵌的精神蜕变史。
