目的分析超长住院患者分布及影响因素,探讨减少超长住院日的措施。方法从江苏省某三甲医院病案管理系统中调取2020年1月1日-2020年12月31日134016例出院患者的住院病案首页资料,对住院时间≥30天的1401例超长住院患者的分布特征进行统计描述,采用Logistic回归模型分析超长住院日的影响因素。结果2020年全院平均住院日为7.13天,其中超长住院患者平均住院日为41.85天。超长住院患者以60岁以上年龄组最多(39.61%);出院科室主要分布在血液科(42.18%)、普通外科(11.85%)、骨科(7.49%)等;疾病类别主要为肿瘤(47.32%)、影响健康状态和与保健机构接触的因素(10.56%)、循环系统疾病(7.07%)等;多因素Logistic回归结果显示,男性(OR=1.188)、离院方式为非医嘱离院或其他(OR=2.046)和死亡病例(OR=3.362)是超长住院的危险因素。结论控制超长住院日对平均住院日影响显著,医院应加强重点人群、重点科室和重点病种管理提高诊疗管理水平,缩短平均住院日。 相似文献

认知障碍是指记忆、语言、理解和判断等一个或多个方面的功能障碍,包括轻度认知障碍和各种类型的痴呆症。痴呆症是认知障碍最严重的表现,是一种导致患者日常生活、社会交往和工作能力发生显著变化的综合征。阿尔茨海默病(AD)是最常见的痴呆症类型,其次是血管性痴呆(VD)和其他神经退行性痴呆[1]。已知年龄与认知功能的退化密切相关。 相似文献

目的:对比观察不同程度屈光参差单眼近视儿童配戴角膜塑形镜1a的双眼近视进展情况。
方法:回顾性病例对照研究。收集2018-06/2019-06于西安市第一医院就诊并验配角膜塑形镜的8~12岁的单眼近视屈光参差患者60例,双眼等效球镜(SE)差值≥2.5D为高度屈光参差组30例,1.0D≤双眼SE差值<2.5D为低度屈光参差组30例。比较两组患者戴镜6mo,1a的双眼眼轴长度(AL)和非戴镜眼SE变化情况。
结果:随访6mo,1a时,高度屈光参差组戴镜眼眼轴增长均少于低度屈光参差组(P<0.001),非戴镜眼眼轴增长量和SE增长均大于低度屈光参差组(均P<0.001),且高度屈光参差组双眼眼轴差缩短幅度均大于低度屈光参差组(P<0.05)。相关性分析显示戴镜前屈光参差度和双眼眼轴差缩短量具有相关性(F=0.293、0.458,均P<0.001)。
结论:单眼近视屈光参差儿童在配戴角膜塑形镜后,高度屈光参差者较低度屈光参差者戴镜眼眼轴增长更慢,而非戴镜眼眼轴和等效球镜度进展更快。配戴角膜塑形镜可有效缩小屈光参差,且戴镜前屈光参差程度越大,双眼轴差缩小越多。 相似文献

中国学龄儿童眼球远视储备、眼轴长度、角膜曲率参考区间及相关遗传因素专家共识(2022年) 总被引:5,自引:0,他引:5
近视眼是影响我国儿童青少年眼健康的焦点问题。远视储备是眼球发生近视前的屈光状态, 是眼轴长度与角膜及晶状体等参数之间动态匹配的结果, 对于近视眼防控意义重大。我国一直缺乏儿童眼球发育参数的指导依据以及遗传因素影响的参考资料, 尤其针对上述参数在儿童眼球正视化过程中变化规律的总结。为了促进儿童青少年近视眼防控工作的标准化, 规范人群筛查和临床治疗, 使社会各界对近视眼的预防干预和评价有据可依, 中华预防医学会公共卫生眼科分会基于我国不同地区儿童青少年的屈光不正调查数据, 针对我国学龄儿童正视眼在不同年龄段眼球远视储备、眼轴长度和角膜曲率的参考区间及相关遗传因素达成共识性意见。 相似文献

目的明确慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)患者住院时间延长的危险因素,为临床患者的早期干预提供依据。方法系统检索中国知网、万方、维普、Pubmed、Web of Science及Cochrane library数据库,收集COPD患者住院时间延长危险因素的队列研究、病例对照研究,检索时限为建库至2020年8月。运用RevMan 5.3软件进行Meta分析。结果纳入12项研究,样本量为23017例。COPD患者住院时间延长的危险因素有9项,即白蛋白水平异常(OR=-2.71)、血红蛋白水平异常(OR=-1.23)、入院FEVI%值异常(OR=-5.83)、GLOD4级(OR=1.57)、合并慢性肾脏疾病(OR=2)、有ICU入住史(OR=7.8)、住院期间使用无创呼吸机(OR=1.94)、住院期间使用有创呼吸机(OR=4.42)及需要进行家庭氧疗(OR=2.36)等。结论临床医护人员应针对危险人群,加强对其评估和管理,从而尽可能地减少COPD患者住院时间延长的发生,改善患者临床预后。 相似文献

Ocular development in children with unilateral congenital cataract and persistent fetal vasculature 下载免费PDF全文

AIM: To investigate the ocular development of patients who had unilateral congenital cataract (CC) combined with persistent fetal vasculature (PFV).
METHODS: This cross-sectional, observational study included patients who had unilateral CC and PFV and those with isolated unilateral CC. Axial length (AL), keratometry, anterior chamber depth (ACD), lens thickness, and vitreous length were obtained. The ocular biometric parameters of the affected eyes of patients with CC and PFV were compared with the fellow eyes and with the affected eyes of patients with isolated CC.
RESULTS: A total of 110 patients were included and divided into 4 groups: group 1 (18 patients with CC and PFV, <24mo), group 2 (22 patients with CC and PFV, ≥24mo), group 3 (35 patients with CC, <24mo), and group 4 (35 patients with CC, ≥24mo). The ALs of the affected eyes were shorter than those of the fellow eyes in group 1 (20.02±1.06 vs 20.66±0.63 mm, P=0.025). While the ALs of the affected eyes were longer than those of the fellow eyes in group 2 (23.18±2.00 vs 22.31±1.06 mm, P=0.044) and group 4 (22.64±1.80 vs 22.02±1.01 mm, P=0.033). The keratometries of the affected eyes were steeper than those of the fellow eyes in group 2 (44.78±1.66 vs 43.83±1.38 D, P=0.041) and group 4 (43.76±1.91 vs 43.34±1.46 D, P=0.043). No difference of ACDs between two eyes was found in all groups (all P>0.05).
CONCLUSION: Compared with the fellow eyes, the ALs of the eyes with unilateral CC and PFV are shorter in patients younger than 24mo and longer in those older than 24mo; the keratometries of the eyes with unilateral CC and PFV are steeper in patients older than 24mo and similar with those younger than 24mo. These findings provide further understanding of ocular development in patients with both CC and PFV. 相似文献

IntroductionThis study aimed to compare the in vivo accuracy of Wirele-X and RootZX II electronic apex locators (EALs) in determining the position of the major foramen using micro–computed tomography (micro-CT) as the analytical tool.MethodsEleven vital teeth planned for extraction from 5 patients were used. After conventional access cavity preparation, root canals were flared and negotiated up to the apical third with sizes 08 and 10 K-files followed by irrigation with 2.5% NaOCl. K-type files were used to determine the working length of the selected canals using Root ZX II and Wirele-X apex locators until their numeric displays read “0.0.” After fixing the silicon stop to the file, teeth were extracted and imaged in a micro-CT device using a double-scan protocol. Image stacks, with and without the file in the root canal, were then co-registered and the measurement error calculated as the absolute difference between the tip of the file and the major foramen. Positive and negative values were recorded when the file tip was detected beyond or short of the major foramen, respectively. Accuracy was determined on stable measurements within ± 0.5 mm when the file tip did not extend beyond the major foramen. The χ2 test was applied to compare the ability of the EALs to detect the position of the major foramen, and the t test for dependent variables was used to verify differences in the 2 measurements obtained in each tooth. Significance level was set at 5%.ResultsWithin a tolerance level of ± 0.5 mm, no significant differences were observed between the tested EALs regarding the absolute distance values (P = .82) or in their ability to detect the position of the major foramen (χ2 = 0.2588; P = .6109). The accuracy of the Root ZX II and the Wirele-X apex locators within ± 0.5 mm were 81.8% and 90.9%, respectively.ConclusionsRoot ZX II and Wirele-X performed similarly regarding the in vivo detection of the major foramen. Using strict criteria, the accuracy of the Root ZX II and the Wirele-X apex locators were 81.8% and 90.9%, respectively. 相似文献
