基于虚拟教研室的公共卫生安全素养培育课程构建及实践

目的:探讨基于虚拟教研室的公共卫生安全素养培育课程构建及实践。方法:选取某医学院校专科护理专业学生(护生)为研究对象,将护理1班45人作为试验组,将护理2班43人作为对照组,对照组对公共卫生安全知识实施线上与线下的常规教学,试验组实施基于虚拟教研室的公共卫生安全素养培育课程。比较两组护生内容掌握情况及学习满意度。结果:试验组护生的学习成绩明显高于对照组(P<0.01),试验组护生对教学的满意度为95.6%(43/45),明显高于对照组(P<0.05)。结论:基于虚拟教研室的公共卫生安全素养培育课程构建既可以广泛促进不同专业教师进行教学研究交流,全面提高教师教书育人能力,又可以使护生在学习过程中接触不同专业、不同领域的知识与技能,注重护生主体作用,提高学习效果和学习满意度。     

Evaluating a Food Pantry–Based Intervention to Improve Food Security,Dietary Intake,and Quality in Midwestern Food Pantries

BackgroundVoices for Food was a longitudinal community, food pantry–based intervention informed by the social ecological model, and designed to improve food security, dietary intake, and quality among clients, which was carried out in 24 rural food pantries across 6 Midwestern states.ObjectiveOur objective was to evaluate changes in adult food security, dietary intake, and quality from baseline (2014) to follow-up (2016), and to assess the role of adult food security on dietary outcomes.DesignA multistate, longitudinal, quasi-experimental intervention with matched treatment and comparison design was used to evaluate treatment vs comparison group changes over time and changes in both groups over time.Participants/settingAdult food pantry clients (n = 617) completed a demographic food security survey, and up to three 24-hour dietary recalls at baseline (n = 590) and follow-up (n = 160).InterventionCommunity coaching served as the experimental component, which only “treatment” communities received, and a food council guide and food pantry toolkit were provided to both “treatment” and matched “comparison” communities.Main outcome measuresChange in adult food security status, mean usual intakes of nutrients and food groups, and Healthy Eating Index-2010 scores were the main outcome measures.Statistical analyses performedLinear mixed models estimated changes in outcomes by intervention group and by adult food security status over time.ResultsImprovements in adult food security score (–0.7 ± 0.3; P = .01), Healthy Eating Index-2010 total score (4.2 ± 1.1; P < .0001), and empty calories component score (3.4 ± 0.5; P <.0001) from baseline to follow-up were observed in treatment and comparison groups, but no statistically significant changes were found for adult food security status, dietary quality, and usual intakes of nutrients and food groups between the 2 groups over time. The intervention effect on dietary quality and usual intake changes over time by adult food security status were also not observed.ConclusionsFood pantry clients in treatment and comparison groups had higher food security and dietary quality at the follow-up evaluation of the Voices for Food intervention trial compared with baseline, despite the lack of difference among the groups as a result of the experimental coaching component.     

安全感在护士评价恐惧与情绪表达冲突中的中介作用

目的调查护士安全感、评价恐惧及情绪表达冲突现状,探讨安全感在护士评价恐惧与情绪表达冲突中的中介作用,为护士有效应对情绪表达提供依据。方法采用安全感量表、正面评价恐惧与负面评价恐惧量表及情绪表达冲突问卷对161名护士进行调查。结果护士的安全感总分(53.84±12.44)分;正面评价恐惧总分(31.78±15.27)分、负面评价恐惧总分(24.89±7.48)分;情绪表达冲突总分(96.26±23.20)分。安全感在正面评价恐惧与情绪表达冲突之间起完全中介作用,在负面评价恐惧与情绪表达冲突之间起部分中介作用。结论护士的安全感、情绪表达冲突处于中等水平,存在着对正面评价及负面评价的恐惧。安全感在护士评价恐惧与情绪表达冲突中起到中介作用。可通过提升安全感及正确对待负面评价,以降低评价恐惧对情绪表达冲突的影响。     

侧卧手术体位对老年患者眼压变化的影响及护理观察要点

目的探讨使用有效的测量工具和在适合的测量时间段采集侧卧手术体位老年患者基础数据,找出患者眼压变化随体位变化的规律,旨在制订有效的护理预防措施。方法选取2019年3—6月在首都医科大学附属北京同仁医院中心手术室完成胸科胸腔镜手术的老年患者31例。使用icare回弹式眼压计分别于患者入手术室后、全身麻醉插管后、侧卧5 min、侧卧30 min、术中1 h、术中2 h、术中3 h、翻身拔管、出室前9个时间点测量双眼眼压,同时记录每个时间点患者的血压、心率数据,记录手术过程中液体出入量、特殊用药等。结果患者侧卧5 min、侧卧30 min、术中1 h、术中2 h、术中3 h的血压与入室后比较,差异有统计学意义(P<0.05);不同时间点的心率比较,差异无统计学意义(P>0.05)。麻醉插管后患者双眼眼压均低于入室时眼压,差异有统计学意义(P<0.05);侧卧30 min、术中1 h、术中2 h、术中3 h的双眼眼压与入室后眼压比较,差异有统计学意义(P<0.05);侧卧5 min、侧卧30 min、术中1 h、术中2 h、术中3 h的受压侧眼压与非受压侧眼压比较,差异有统计学意义(P<0.05)。Pearson相关分析显示,患者平均动脉压与受压侧眼及非受压侧眼的眼压均无相关性(r值分别为-0.1138、0.0179,P>0.05)。进入手术间时患者测试视力与术后6 h回病房后测试视力比较,差异无统计学意义(P>0.05)。结论胸腔镜手术老年患者的眼压随手术体位变化而波动,从侧卧5 min开始眼压出现变化,2 h内受压侧眼眼压达到高峰,体位恢复平卧位后,眼压随即恢复到入室时水平。本研究未发现血压与眼压变化的相关性。     

护士心理安全感在组织支持感与敬业度的中介作用

目的探讨护士组织支持感、心理安全感与敬业度的关系,为提升护士敬业度及改善护理管理提供依据。方法采用一般资料调查表、组织支持感量表、心理安全感量表及盖洛普Q12调查表对天津市3所三级甲等医院的414名护士进行问卷调查。结果护士敬业度总均分为(2.09±0.38)分,处于中等水平,组织支持感总均分为(3.19±0.31)分,心理安全感总均分为(3.42±0.45)分。护士敬业度、组织支持感、心理安全感三者呈正相关(P0.05,P0.01),心理安全感在组织支持感与敬业度的关系中发挥部分中介作用,中介效应为0.34,心理安全感与组织支持感共同解释敬业度总变异的21%。结论护士敬业度处于中等水平,护理管理者应创造良好的组织支持环境,给予护士更多情感支持以提高护士的心理安全感,从而提高其敬业度。

Perplexing condition of child full immunisation in economically better off Gujarat in India: An assessment of associated factors

BackgroundDespite decent progress in Children Full Immunisation (CFI) in India during the last decade, surprisingly, Gujarat, an economically more developed state, had the second-lowest coverage of CFI (50%) in the country, lower than economically less developed states such as Bihar (62%). Further, the proportion of children with no immunisation in Gujarat has risen from 5% in 2005 to 9% in 2016. This paper investigated factors associated with the low level of CFI coverage in Gujarat.MethodsThe study used two types of datasets: (1) the information on immunisation from 7730 children aged 12–23 months and their mothers from the fourth round of the Gujarat chapter of National Family Health Survey (NFHS 2015–16). (2) A macro (district) level data on both supply and demand-side factors of CFI are compiled from multiple sources. Bivariate and multivariate linear and logistic regression techniques were employed to identify the factors associated with CFI coverage.ResultsIn Gujarat, during 2015–2016, 50% of children aged 12–23 months did not receive full immunisation. The odds of receiving CFI was higher among children whose mothers had a Maternal and Child Protection (MCP) card (OR: 1.97, 95% CI 1.48–2.60) and those who received “high” maternal health services utilisation (OR: 1.59, 95% CI 1.10–2.26) compared to their counterparts. The odds of receiving CFI was about three times higher among the richest households (OR: 6.50, 95% CI 3.75–11.55) compared to their counterparts in the poorer households. Macro-level analyses suggest that poverty, maternal health care, and higher-order births are defining factors of CFI coverage in Gujarat.ConclusionsIn order of importance, focusing on poverty, economic inequalities, pregnancy registration, and maternal health care services utilisation are likely to improve receiving CFI uptake in Gujarat. The disadvantageous position of urban areas and non-scheduled tribes in CFI coverage needs further investigation.
