目的 探讨医院信息系统中增加住院陪护管理功能的应用效果。方法 基于互联网医院、智慧医院等信息系统,开发信息化住院陪护管理功能,包括流行病学史调查、免费核酸申请、电子陪护证办理、体温监测登记及上报和统计查询。该功能与医院智慧护理链接后全院应用。比较功能应用前和应用后的遵医嘱一患一陪达标率、有效陪护证达标率、体温监测并登记日上报达标率和陪护证使用追溯率,评价护士和管理者疫情防控管理的人均耗时以及对该管理功能的满意度。结果 应用信息化陪护管理功能后,一患一陪达标率、有效陪护证达标率、体温监测并登记日上报达标率和陪护证使用追溯率显著高于应用前(均P<0.05);护士陪护管理人均耗时从(554.13±30.77)s降至(311.67±21.54)s(P<0.05);护士和管理者对该信息化陪护管理功能的满意度显著提高(均P<0.05)。结论 信息化住院陪护管理功能的应用有效提升了疫情期间陪护的管理质量和管理效率,提高了一线护士和管理者的满意度。  相似文献

BackgroundFew studies have investigated the impact of web-based physical activity interventions on mental health outcomes. Therefore, this study examined the impact of a web-based personally tailored physical activity intervention on depression, anxiety, stress and quality of life.Methods501 participants were randomised into either a control group or a pooled intervention condition who received a 3-month web-based personally tailored physical activity intervention. Previously, this intervention has demonstrated to improve self-reported physical activity, but not device-measured physical activity. At baseline, 3- and 9-months, depression, anxiety and stress were assessed using the DASS21, and quality of life was assessed using the SF-12V2. General linear mixed models examined differences between groups over time.ResultsMost participants (>80%) reported normal levels of depression, anxiety or stress. Relative to baseline levels, significant reductions of depression, anxiety, stress and the SF12 mental health component were observed in the pooled intervention group at 3 and 9 months. Relative to the control group, significant reductions were observed in the pooled intervention group for depression and stress (3-months only) and anxiety (3- and 9-months), but not quality of life.ConclusionA web-based physical activity intervention can result in positive mental health outcomes, even in the absence of device-measured physical activity improvements. However, these findings need to be confirmed in future studies.Trial registration numberACTRN12615000057583.  相似文献

随着手机APP对人们日常工作和生活方式的改变,中医类APP日益得到关注。文章基于内容分析法对目前中医类APP现状进行梳理,分析存在的问题,对未来中医类APP的设计和开发提出建议。以每一个APP为分析单元,从一般情况、主要功能、用户评价等3个方面进行分析,建立了7个维度22个细目的编码体系,进行频数统计和分析。发现目前中医类APP功能丰富,用户广泛,成为中医药服务及中医科学传播的重要载体,具有良好的用户粘度及巨大市场需求,但存在质量良莠不齐、内容资源不佳等问题。提出中医类APP开发应符合中医药发展战略的方向,应进一步规范中医类APP隐私政策和相关法律法规;并探索中医类APP的评价标准和评价指标体系,促进和规范中医类APP的质量提升和不断发展。  相似文献

The coronavirus disease 2019 (COVID-19) has currently caused the mortality of millions of people around the world. Aside from the direct mortality from the COVID-19, the indirect effects of the pandemic have also led to an increase in the mortality rate of other non-COVID patients. Evidence indicates that novel COVID-19 pandemic has caused an inflation in acute cardiovascular mortality, which did not relate to COVID-19 infection. It has in fact increased the risk of death in cardiovascular disease (CVD) patients. For this purpose, it is dramatically inevitable to monitor CVD patients’ vital signs and to detect abnormal events before the occurrence of any critical conditions resulted in death. Internet of things (IoT) and health monitoring sensors have improved the medical care systems by enabling latency-sensitive surveillance and computing of large amounts of patients’ data. The major challenge being faced currently in this problem is its limited scalability and late detection of cardiovascular events in IoT-based computing environments. To this end, this paper proposes a novel framework to early detection of cardiovascular events based on a deep learning architecture in IoT environments. Experimental results showed that the proposed method was able to detect cardiovascular events with better performance (95.30% average sensitivity and 95.94% mean prediction values).  相似文献

Medical interactions around reproduction are increasingly extending beyond the physician's office and onto the Internet, where negotiation with medical authority occurs in complex and dynamic ways. Recently, scholars have noted the Internet's potential for creating spaces where women can dialogue with and reconstruct medical authority, yet this growing body of work is overwhelming heteronormative. This paper thus interrogates how lesbian women use the Internet to challenge, deploy, and rework medical authority around reproduction while navigating the transition to parenthood. I draw from 17 online journals authored by lesbian couples during the conception, pregnancy, and birth of their first child, each spanning between 18 months and 2 years, in order to understand how the transition process unfolds over time. I argue that lesbian couples engage with medical authority when seeking affirmation and normalisation yet discard and publicly reject the heteronormative assumptions that accompany reproductive medicine. Further, they chart a new process that I term ‘constructing queer mother‐knowledge’, in which they critique and balance knowledges from institutionalised medicine, their own bodies, and their queer communities. With this new concept, I complicate understandings of lesbian mothers‐to‐be and their interactions with medical authority as they build subversive families.  相似文献

Introduction

Websites serve as information and communication platforms; hence, they are important tools for the self-promotion of hospitals. In 2010, Selig et al. evaluated the online presence of burn centers in Germany, Austria, and Switzerland based on 37 quality criteria. This study aimed to re-evaluate these websites to assess their development over the past 6.5 years.

Materials and methods

Websites of the German-speaking burn centers were re-evaluated according to criteria previously described by Selig et al. Particular attention was paid to specific information on burns. Additionally, the implementation of social media platforms was investigated.

Results

There was an overall increase in the quality of information published on websites. There was a considerable improvement recorded, especially in the categories of “teaching” and “patient care.” However, burn-specific information was found to be still sparse. Over 50% of the hospitals were present on social media.

Conclusions

Although the quality of information published on German-speaking burn center websites increased, they must be further developed, especially regarding burn-related information. Moreover, a clear structure and design could prevent long searches and facilitate an easier flow of information. The interface from websites and social media platforms appear to be an important tool for up-to-date self-promotion.  相似文献

我国的家庭医生签约服务正在如火如荼地进行着,目前关于家庭医生签约的评价、见解、效果反馈的研究多来自管理专业、经济学专业、公共卫生专业的学者,尚缺乏来自签约主体之一的医务人员的视角。本文将从一线全科医生即家庭医生签约服务执行者的视角,阐述现阶段基层医疗信息系统服务家庭医生签约的现状,并对其中存在的问题和可能的解决办法进行探讨。  相似文献
