脑卒中个案管理师准入标准和工作职责方案的构建

目的 构建脑卒中个案管理师准入标准和工作职责,为制订符合中国国情的脑卒中个案管理师人才培养方案和工作标准提供参考依据。方法 基于文献研究、脑卒中患者管理现状调查、专家会议讨论和预咨询,构建准入标准和工作职责初稿;采用德尔菲专家咨询法,对全国8个省市的20名专家进行问卷咨询。 结果 2轮专家咨询的问卷有效回收率分别是95.2%和100.0%。第2轮咨询中,专家权威系数为0.910,准入标准和工作职责的一、二、三级指标专家意见的肯德尔和谐系数分别为0.193、0.155、0.141（P<0.05）和0.445、0.156、0.134（P<0.05）。最终形成的脑卒中个案管理师准入标准包括一级指标3项（基础条件、专业能力、综合能力）,二级指标7项,三级指标17项。工作职责包括一级指标4项（评估、计划、实施、评价）,二级指标17项,三级指标79项。 结论 经专家咨询确定的脑卒中个案管理师准入标准和工作职责方案具有较好的科学性、实用性、可行性和创新性,能为脑卒中个案管理护理实践提供理论依据。     

Spill Over Effects of Inpatient Bed Capacity on Accident and Emergency Performance in England

The English National Health Service (NHS) has failed to meet the four-hour waiting time target to admit, transfer or discharge 95 per cent of patients attending Accident and Emergency Departments (A&E) since 2013. A growing number of patients requiring inpatient care are waiting on trolleys longer than four hours before admission to a hospital bed. This study examines the role of bed occupancy in the deterioration of A&E performance in the NHS. Longitudinal panel data methods are used to analyse hospital data (n = 72,129,886) for 143 Trusts from 1^st June 2016 to 31^st October 2019. The average bed occupancy rate across the study period was 93.2%. A 1% increase in bed occupancy was associated with a 9.5 percentage point decrease in the Trusts’ probabilitay of meeting the waiting target, and an approximately 6 patient increase in four hours to 12 -hs trolley waits per 1,000 admissions. These relationships became more pronounced with rising bed occupancy levels above a 90% threshold. Bed occupancy is associated with significant negative spill-over effects on A&E performance. We estimate a minimum investment in 3,861 additional inpatient beds across the NHS to improve A&E performance in England. Relevant lessons can be derived for health care systems that have observed similar trends in increasing bed occupancy and deteriorations in A&E performance, including Ireland, Canada and Israel.     

Research progress on magnetic resonance imaging-guided proton therapy for tumors

With the application of magnetic resonance imaging (MRI)-guided photon therapy, the concept of combining real-time MRI guidance with proton therapy, namely, MRI-guided proton therapy (MRPT), has attracted widespread attention. It is expected that MRPT canmitigate the uncertaintiesduring the treatment of proton therapy to make full use of the physical advantages of protons. However, multiple electromagnetic interactions between proton therapy and MRI-guided systems may lead to mutual interference between the two systems. This article review the research progress on the MRPT system, aiming to provide certain reference for the design of MRPT system.     

ⅢA-N2期非小细胞肺癌新辅助治疗的研究现状

ⅢA-N2期非小细胞肺癌(NSCLC)是一组异质性较大的疾病,最佳治疗模式仍存在争议。如何将化疗、放疗、靶向及免疫治疗等多种治疗手段合理的应用于这部分患者的新辅助治疗中,目前尚无定论。本文就NSCLC新辅助治疗相关研究进行综述,对不同新辅助治疗模式进行疗效及安全性方面的评估。     

静脉血栓栓塞症风险评估模型研究进展与启示

通过文献研究，总结国内外静脉血栓栓塞症各类评估工具的优缺点及适用范围。指出我国与欧美国家人群存在种族、疾病谱和遗传因素等方面的差异，国外量表所纳入的危险因素并不一定能准确、完整地反映我国患者的风险状况。应借鉴国外评估工具的构建方法，基于我国VTE患者数据进行多中心、大样本的回顾性研究，从而构建更适合我国人群的、更准确的VTE风险评估模型。     

Effect of multidisciplinary team care on the risk of recurrence in breast cancer patients: A national matched cohort study

BackgroundCancer has been the leading cause of death in the past decade in Taiwan, with breast cancer being the most common type of cancer in females. Very few studies looked at the risk of recurrence in patients who received multidisciplinary team (MDT) care. We analyzed the influence of MDT on the risk of recurrence and death in breast cancer patients.MethodIn this retrospective study, we included newly diagnosed patients from 2004 to 2010. The study included 9,266 breast cancer patients who were enrolled in MDT care and 9,266 patients who were not. The study used log-rank test to analyze patients’ characteristics, hospital characteristics, cancer staging, and treatment methods to compare the recurrence rates in MDT care and non-MDT care participants. We used Cox proportional hazards model to examine the effect of MDT and associated factors on the risk of recurrence and mortality of breast cancer patients.ResultsRelative risk of recurrence was lower for patients who received MDT care than for patients who did not (HR, 0.84; 95%CI: 0.70–0.99) after matching. The mortality risk for breast cancer patients with relapse was 8.48 times (95%CI: 7.53–9.54) than that for patients without relapse.ConclusionsThe relative risk of recurrence and death was significantly lower for breast cancer patients who received MDT care than for those who did not. We suggest that MDT care be implanted in the National Health Policy settings of breast cancer patients.
