提出一种面向医院患者的视觉监控跌倒检测算法,解决患者由于意外跌倒不能被及时发现的问题,为医护人员快速处理患者跌倒等异常行为提供必要的技术保障。方法:首先,基于深度神经网络模型检测监控图像中人体关节点(如肩部、肘部、腕部、胯部、膝关节等)在图像中的位置,再根据亲和度向量场模型提取人体骨架,最后计算患者躯干、腿部与地面的夹角作为判别性特征,判断监控区域内是否有患者出现意外跌倒。结果:实验结果表明,本文所提算法在实际的医院监护环境中的处理速度高达25帧/s,检测准确率高达96%。结论:该方法能够实时、准确地提取医院环境下患者的行为特征,并针对意外跌倒情况发出警报,为医护人员监测患者跌倒等异常行为提供更准确、方便的计算机辅助医疗护理方法。 相似文献

为满足肠道传染病防控需要,2012年起上海市创新探索腹泻病综合监测模式,监测科学布点、系统采样、多病原集合、联通医院信息系统,实现了"一个监测、多个病种;一份样本,多种病原"的监测模式,对全年龄段人群进行持续的主动监测,监测内容包括人口学、临床医学、流行病学、病原检测、药敏监测等病例信息。监测取得了如下初步成效:掌握真实世界的腹泻疾病特征及周期变化规律,发现本市腹泻的最主要病原体为诺如病毒;发现了少见病原体或病原体血清型,提供疫情溯源线索;促进了公共卫生机构和临床医疗机构的信息共享,为临床诊疗提供科学依据。未来腹泻病综合监测将朝扩展监测广度和监测深度、智能化辅助诊疗、暴发疫情预警、流行趋势预测、应用检测新技术等方向提升。 相似文献

Identifying transmission of hot spots with temporal trends is important for reducing infectious disease propagation. Cluster analysis is a particularly useful tool to explore underlying stochastic processes between observations by grouping items into categories by their similarity. In a study of epidemic propagation, clustering geographic regions that have similar time series could help researchers track diffusion routes from a common source of an infectious disease. In this article, we propose a two-stage scan statistic to classify regions into various geographic clusters by their temporal heterogeneity. The proposed scan statistic is more flexible than traditional methods in that contiguous and nonproximate regions with similar temporal patterns can be identified simultaneously. A simulation study and data analysis for a dengue fever infection are also presented for illustration. 相似文献

IntroductionHip displacement is common in cerebral palsy (CP) and is related to the severity of neurological and functional impairment. It is a silent, but progressive disease, and can result in significant morbidity and decreased quality of life, if left untreated. The pathophysiology of hip displacement in CP is a combination of hip flexor-adductor muscle spasticity, abductor muscle weakness, and delayed weight-bearing, resulting in proximal femoral deformities and progressive acetabular dysplasia. Due to a lack of symptoms in the early stages of hip displacement, the diagnosis is easily missed. Awareness of this condition and regular surveillance by clinical examination and serial radiographs of the hips are the key to early diagnosis and treatment.Hip surveillance programmesSeveral population-based studies from around the world have demonstrated that universal hip surveillance in children with CP allows early detection of hip displacement and appropriate early intervention, with a resultant decrease in painful dislocations. Global hip surveillance models are based upon the patients’ age, functional level determined by the Gross Motor Function Classification system (GMFCS), gait classification, standardized clinical exam, and radiographic indices such as the migration percentage (MP), as critical indicators of progressive hip displacement.ConclusionDespite 25 years of evidence showing the efficacy of established hip surveillance programmes, there is poor awareness among healthcare professionals in India about the importance of regular hip surveillance in children with CP. There is a need for professional organizations to develop evidence-based guidelines for hip surveillance which are relevant to the Indian context. 相似文献

目的分析2015—2018年深圳市南山区老年人伤害监测病例分布及特征,为预防控制老年伤害发生提供依据。方法通过伤害监测系统收集2015—2018年间因伤害首次在深圳市南山区伤害监测哨点医院急诊室就诊的60岁及以上老年病例资料,并进行描述性分析。结果共收集老年伤害病例10616例,男女性别比为1∶1.35;伤害发生原因前五位依次为跌倒/坠落(57.12%)、动物伤(13.97%)、刀/锐器伤(10.41%)、钝器伤(8.18%)、道路交通伤害(7.56%)。动物伤在各年份的占比呈逐年上升的趋势;伤害发生地点主要为家中(45.71%);伤害发生时以进行休闲活动时为主(67.96%);伤害性质以挫伤/擦伤(45.79%)、锐器伤/咬伤/开放伤(28.23%)、骨折(12.79%)居多;伤害严重程度多数为伤势较轻,预后良好。结论老年伤害多发于女性,跌倒/坠落、动物伤及道路交通伤害是老年群体伤害防控的重点。 相似文献

In our study, we evaluated the effectiveness of upper gastrointestinal (GI) endoscopy as an instrument for early gastric cancer (GC) detection in Lynch syndrome (LS) patients by analyzing data from the registry of the German Consortium for Familial Intestinal Cancer. In a prospective, multicenter cohort study, 1128 out of 2009 registered individuals with confirmed LS underwent 5176 upper GI endoscopies. Compliance was good since 77.6% of upper GI endoscopies were completed within the recommended interval of 1 to 3 years. Forty‐nine GC events were observed in 47 patients. MLH1 (n = 21) and MSH2 (n = 24) mutations were the most prevalent. GCs in patients undergoing regular surveillance were diagnosed significantly more often in an early‐stage disease (UICC I) than GCs detected through symptoms (83% vs 25%; P = .0231). Thirty‐two (68%) patients had a negative family history of GC. The median age at diagnosis was 51 years (range 28‐66). Of all GC patients, 13 were diagnosed at an age younger than 45. Our study supports the recommendation of regular upper GI endoscopy surveillance for LS patients beginning no later than at the age of 30. 相似文献
