卡通画与背景音乐在儿科穿刺室的应用

目的探讨一种服务方式,旨在减轻患儿痛苦,提高穿刺成功率,提升患者满意度。方法将儿科静脉穿刺的2 869例患者分成2组,在普通穿刺室静脉穿刺者为对照组(1 417例),在经过卡通画装饰墙面、播放儿歌背景音乐后的穿刺室中脉穿刺者为观察组(1 452例),比较两组患者一次穿刺成功率、头皮静脉穿刺疼痛程度、对护理工作的满意度。结果观察组一次穿刺成功率与患者对护士工作的满意度均高于对照组,观察组疼痛程度较轻,差异有统计学意义(P<0.05)。结论卡通画与背景音乐在儿科穿刺室的应用,可缓解静脉穿刺给患儿造成的疼痛,提高一次穿刺成功率,提升患者满意度。     

提高重症患者气管插管医护配合默契度的效果研究

目的:通过持续质量改进的实施与效果评价,提高重症患者气管插管医护配合默契度。方法:应用PDCA进行重症患者气管插管医护配合的现状分析、实施改进措施、数据查检,比较PDCA实施前后医护配合默契度及医生对护士操作配合的满意度。结果:实施PDCA后医护配合默契度(90.00±9.07)分,高于实施前(60.00±14.95)分(P<0.05);医生对护士操作配合的Likert scale 5分满意度评分,4分以上占97.14%,高于实施前77.14%(P<0.05)。结论:通过持续质量改进,可以增进医护沟通,对重症患者气管插管进行科学管理,提高医护配合默契度,提高抢救效率,保证患者生命安全。     

基于灰色关联度分析和聚类分析的3种滇产重楼抗肝癌作用谱效关系探索

目的:研究长柱重楼、滇重楼和南重楼的HPLC指纹图谱与其抗肝癌作用的谱效关系,为明确重楼抗肝癌作用的物质基础提供实验依据。方法:采用HPLC建立3种重楼提取物的指纹图谱,流动相乙腈(A)-水(B)梯度洗脱(0～10 min,20%A; 10～20 min,20%～25%A; 20～30 min,25%～30%A; 30～40 min,30%～35%A; 40～50 min,35%～40%A; 50～60 min,40%A; 60～75 min,40%～45%A; 75～80 min,45%～60%A),流速0. 9 m L·min~(-1),检测波长203 nm;利用噻唑蓝(MTT)比色法测定3种重楼提取物对肝癌HepG2细胞的增殖抑制作用,计算半数抑制浓度(IC_(50));运用聚类分析(HCA)和灰色关联度分析(GRA)研究3种重楼指纹图谱和抗肝癌作用的关系,找出对抗肝癌作用贡献较大的成分。结果:在3种重楼的HPLC指纹图谱中,确定其中11个色谱峰为共有峰。作用时间72 h时长柱重楼、滇重楼、南重楼的IC_(50)分别为148. 33,178. 87,208. 09 mg·L~(-1),其中长柱重楼的抗肝癌活性最强。灰色关联度结果显示,滇重楼共有峰中关联度较高的为1～10号峰,长柱重楼共有峰关联度较高的为1～7号峰,南重楼共有峰中关联度较高的为1～4,6～10,N1号峰,与IC_(50)关联度均0. 7。各重楼变量的聚类分析结果显示,可与IC_(50)聚为一类的色谱峰的关联度均 0. 7。结论:建立了3种重楼的HPLC指纹图谱,重复性良好。3种重楼中的1～4,6和7号色谱峰对抗肝癌药效贡献最大。     

针刀松解激痛点治疗颈源性头痛39例影响

目的分析针刀松解激痛点治疗方法用于颈源性头痛患者的效果。方法对医院接受针刀松解激痛点治疗的39例颈源性头痛患者纳入试验组,选于2017年2月—2018年9月,抽取同期接受针刺治疗的39例颈源性头痛患者纳入对照组,评比两组治疗有效总计率、治疗前和治疗3个疗程后头痛程度评分值、头痛维持时间、头痛发生频率。结果试验组治疗有效总计率明显高于对照组统计值(P<0.05)。试验组治疗3个疗程后头痛程度评分值、头痛维持时间、头痛发生频率显著低于治疗前及对照组统计值(P<0.01)。结论对颈源性头痛患者实行针刀松解激痛点治疗的效果较优。     

The formation of physician patient sharing networks in medicare: Exploring the effect of hospital affiliation

This study explores the forces that drive the formation of physician patient sharing networks. In particular, I examine the degree to which hospital affiliation drives physicians' sharing of Medicare patients. Using a revealed preference framework where observed network links are taken to be pairwise stable, I estimate the physicians' pair‐specific values using a tetrad maximum score estimator that is robust to the presence of unobserved physician specific characteristics. I also control for a number of potentially confounding patient sharing channels, such as (a) common physician group or hospital system affiliation, (b) physician homophily, (c) knowledge complementarity, (d) patient side considerations related to both geographic proximity and insurance network participation, and (e) spillover from other collaborations. Focusing on the Chicago hospital referral region, I find that shared hospital affiliation accounts for 36.5% of the average pair‐specific utility from a link. Implications for reducing care fragmentation are discussed.     

Development of a Simulation-Based Mastery Learning Curriculum for Breaking Bad News

Introduction

Physician communication impacts patient outcomes. However, communication skills, especially around difficult conversations, remain suboptimal, and there is no clear way to determine the validity of entrustment decisions. The aims of this study were to 1) describe the development of a simulation-based mastery learning (SBML) curriculum for breaking bad news (BBN) conversation skills and 2) set a defensible minimum passing standard (MPS) to ensure uniform skill acquisition among learners.
