Environmental Sustainability of Hospital Foodservices across the Food Supply Chain: A Systematic Review

BackgroundHospitals have a responsibility to support human health, and given the link between human and environmental health, hospitals should consider their environmental impacts. Hospital foodservices can negatively affect the environment at every stage of the food supply chain (production/procurement, distribution, preparation, consumption, and waste management/disposal).ObjectiveTo systematically identify and synthesize the following across the hospital patient food/nutrition supply chain: environmental and associated economic impacts of foodservice; outcomes of strategies that aim to improve the environmental sustainability of foodservice; and perspectives of patients, staff, and stakeholders on environmental impacts of foodservice and strategies that aim to improve the environmental sustainability of foodservice.MethodsEight electronic databases (ie, Cumulative Index to Nursing and Allied Health Literature Plus, Embase via Ovid, Global Health, National Health Service Economic Evaluation Database, Ovid Medline, ProQuest Environmental Science Collection, Scopus, and Web of Science) were searched from database inception to November 2018 for original research conducted across any stage of the hospital food supply chain (from production/procurement to waste management/disposal) that provides food/nutrition to patients, with no restrictions on language or study design. Titles/abstracts then full texts were screened independently by two authors. The Mixed Methods Appraisal Tool was used for quality appraisal for included studies. Data were synthesized narratively.ResultsFrom 29,655 records identified, 80 studies met eligibility criteria. Results were categorized into production/procurement (n=12), distribution (n=0), preparation (n=6), consumption (n=49), waste management/disposal (n=8), and multiple food supply chain aspects (n=5). The environmental impact most widely explored was food waste, with many studies reporting on food waste quantities, and associated economic losses. Strategies focused on reducing food waste by increasing patients’ intake through various foodservice models. Perspectives identified a shared vision for sustainable foodservices, although there are many practical barriers to achieving this.ConclusionThe literature provides examples across the hospital food supply chain that demonstrate how environmental sustainability can be prioritized and evaluated and the opportunities for credentialed nutrition and dietetics practitioners to contribute. Future studies are warranted, particularly those measuring environmental impacts and testing the effects of sustainable strategies in the distribution, preparation, and waste management stages.     

Prevalence and clinical characteristics of children with medical complexity in Tottori Prefecture,Japan: A population-based longitudinal study

ObjectivesTo investigate the prevalence and background of children with medical complexity (CMC) and its secular trend in Japan.MethodsCMC were defined as patients under the age of 20 years requiring medical care and devices. The patients were enrolled using the national health insurance claims data of three hospitals and two rehabilitation centers in Tottori Prefecture. The study period was divided into three periods: Period 1, 2007–2010; Period 2, 2011–2014; and Period 3, 2015–2018.ResultsA total of 378 CMC were enrolled. The prevalence of CMC was 1.88 per 1000 population among subjects aged <20 years in 2018, and it increased by approximately 1.9 times during the study period. The number of CMC who presented with severe motor and intellectual disabilities did not change from Period 1 to Period 3. Meanwhile, the number of CMC who had relatively preserved motor and intellectual abilities increased from 58 to 98. The proportion of CMC who required respiratory management and oxygen therapy increased by 1.3 and 1.8 times, respectively. By contrast, the proportion of CMC who need tube feeding decreased significantly between periods 1 and 3 (P < 0.05).ConclusionsThe prevalence of CMC increased almost twice during the 12-year study period; however, the increase in the number of patients with relatively preserved motor and intellectual abilities was pronounced. This study showed that the need for medical care and devices differed based on the underlying disorders and severity of CMC; therefore, individualized medical, welfare, and administrative services and education about the various types of CMC must be provided.     

商业医疗保险参保的供给影响因素研究——基于CGSS2013数据的实证分析

运用Prebit模型分析CGSS2013家户微观数据和保险供给宏观数据,探究影响商业医疗保险参保的因素,发现供给不足制约居民参保,对西部、中部和农村地区影响显著。家庭财富不足、保险知识缺乏、基本医疗保险也影响居民参保。主张推动保险供给侧结构性改革,保险公司增设分支机构,补齐供给短板。政府增加农民收入,普及保险知识,提供有限保障。     

“MMIF+PBL”教学法在神经外科专科教学中的应用

专科研究生的培养是医学教育中不可或缺的部分,传统的教学模式学生主动性较差,知识传授无法跟上知识更新的速度。PBL教学法(problem based learning)以学生为主体、问题为导向、小组讨论为主要形式,老师为引导者,学生主动进行知识探索,培养自身"归纳"与"查新"能力。多模态影像融合技术将影像信息进行数字化综合处理,并进行可视化,广泛用于临床实践中。两者相结合打破传统教材章节框架的束缚,以具体患者诊疗过程为线索,将枯燥的课本知识变为生动的小组讨论,将抽象的解剖学知识进行三维可视化,并以规范化的形式进行课程实施,理论联系实际,提高了教学效率,并消除时间与场地的限制,使教学效率最大化。本文比较了传统教育模式与新的教育模式,在培养研究生的"归纳"与"查新"能力方面,新的教学模式效率更高,更适合现代神经外科研究生教育。     

案例教学法在药剂科临床实习中的应用效果分析

目的研究案例教学法(CBL)在药剂科临床实习中的应用效果。方法将本院2018年1月-12月实习生252例随机分为两组各126例,其中观察组采用CBL进行教学,对照组则给予传统教学方法,比较两组实习后教学成绩和实习生学习主动性。结果干预后,观察组抗菌药物、激素类药物、抗心律失常药物、抗肿瘤药物及解毒药物考核成绩均高于对照组;观察组学习积极主动性量表学习驱动力、深入学习、控制学习、扎实学习评分及总分高于对照组,差异均有统计学意义(P<0.05)。结论CBL用于药剂科临床实习可有效提升实习生学习兴趣和主动性,从而提升其临床知识掌握水平和运用能力。

基于清晰集定性比较分析的地方政府县域医共体创新实践影响因素及其组合路径分析

背景地方政府创新的影响因素分析一直是地方治理创新研究的重要议题。目的探究影响地方政府县域医共体创新实践的因素，并分析其组合路径。方法于2021年3月，以中国医院协会医共体分会举办的第二届"寻找县域医共体实践价值案例"评选活动的初选结果为案例源，将"政策创新类型"作为结果变量（中央主导型创新/地方回应型创新=0，地方自发型创新=1），以经济发展水平、行政层级、地理区位、问题属性及平台作为条件变量，采用清晰集定性比较分析（csQCA）法，通过必要条件分析、充分条件组合分析，探究影响地方政府县域医共体创新实践的因素并构建地方政府县域医共体创新实践的影响路径模型。结果5个条件变量一致性均<0.9，即经济发展水平、行政层级、地理区位、问题属性及平台均不是地方自发型创新的必要条件。条件变量组合分析（基于中间解）结果显示，共得到5组前因条件组合，分别为：经济发展水平*~地理区位*平台，行政层级*~地理区位*平台，经济发展水平*问题属性*平台，~经济发展水平*地理区位*~问题属性*平台，经济发展水平*行政层级*地理区位*问题属性（*表示"且"，~表示"非"）。5组前因条件组合一致性指标均为1，原始覆盖率为0.14~0.43，净覆盖率为0.14~0.43，总体覆盖率为1。地方政府县域医共体创新实践主要呈现出两类模式，即平台型创新模式和动机型创新模式。结论若要实现高水平的医共体创新实践，应该关注政策与当地经济发展水平之间的强相关性，激活地方政府的主动创新意愿，以及加强对县域医共体的平台支持。本研究对于理解地方政府县域医共体创新实践的机理乃至地方政府创新都具有一定价值。
