Impact of Laboratory Value Flowsheet in Electronic Health Record (EHR) Documentation Time

Research on the use of EHR is contradictory since it presents contradicting results regarding the time spent documenting. There is research that supports the use of electronic records as a tool to speed documentation;and research that found that it is time consuming. The purpose of this quantitative retrospective before-after project was to measure the impact of using the laboratory value flowsheet within the EHR on documentation time. The research question was: “Does the use of a laboratory value flowsheet in the EHR impact documentation time by primary care providers (PCPs)?” The theoretical framework utilized in this project was the Donabedian Model. The population in this research was the two PCPs in a small primary care clinic in the northwest of Puerto Rico. The sample was composed of all the encounters during the months of October 2019 and December 2019. The data was obtained through data mining and analyzed using SPSS 27. The evaluative outcome of this project is that there is a decrease in documentation time after implementation of the use of the laboratory value flowsheet in the EHR. However, patients per day increase therefore having an impact on the number of patients seen per day/week/month. The implications for clinical practice include the use of templates to improve workflow and documentation as well as decreasing documentation time while also increasing the number of patients seen per day. .

An Investigation on the Barriers and Facilitators of the Implementation of Electronic Health Records (EHR)

The application of technology in health care, in the form of electronic health records (EHR), is the most important and necessary issue in order to improve the quality of health care, and studies have shown that, not only is it a way to integrate information and represent the condition of patients, and a dynamic source for health care, however it leads to gain access to clinical information and records, electronic communications, comprehensive training and management, and ultimately enhancing the public health;the aim of this study is to investigate the factors influencing the implementation of EHR, which are known as barriers and facilitators. The research is conducted in the form of a review research, and with the help of the Keywords of EHR;barriers and facilitators, articles, from 2008 to 2013, were searched and studied in the Internet-databases. The results of the studies show that the most effective factors include: efficiency, motivation, management, and the participation of end users. Factors such as technical aspects ease of use, available resources, and human resources, have limited effects. And security and privacy, the expected output, lack of time, and workload have relative effects, and also the relation between the patient and clinical staff, has no effects in the process of implementing EHR.

Hyperledger Fabric Blockchain: Secure and Efficient Solution for Electronic Health Records

Background:Electronic Health Record(EHR)systems are used as an efficient and effective technique for sharing patient’s health records among different hospitals and various other key stakeholders of the healthcare industry to achieve better diagnosis and treatment of patients globally.However,the existing EHR systems mostly lack in providing appropriate security,entrusted access control and handling privacy and secrecy issues and challenges in current hospital infrastructures.Objective:To solve this delicate problem,we propose a Blockchain-enabled Hyperledger Fabric Architecture for different EHR systems.Methodology:In our EHR blockchain system,Peer nodes from various organizations(stakeholders)create a ledger network,where channels are created to enable secure and private communication between different stakeholders on the ledger network.Individual patients and other stakeholders are identified and registered on the network by unique digital certificates issued by membership service provider(MSP)component of the fabric architecture.Results:We created and implemented different Chaincodes to handle the business logic for executing separate EHR transactions on the network.The proposed fabric architecture provides a secure,transparent and immutable mechanism to store,share and exchange EHRs in a peer-to-peer network of different healthcare stakeholders.It ensures interoperability,scalability and availability in adapting the existing EHRs for strengthening and providing an effective and secure method to integrate and manage patient records among medical institutions in the healthcare ecosystem.

Using AI and Precision Nutrition to Support Brain Health during Aging

Artificial intelligence, often referred to as AI, is a branch of computer science focused on developing systems that exhibit intelligent behavior. Broadly speaking, AI researchers aim to develop technologies that can think and act in a way that mimics human cognition and decision-making [1]. The foundations of AI can be traced back to early philosophical inquiries into the nature of intelligence and thinking. However, AI is generally considered to have emerged as a formal field of study in the 1940s and 1950s. Pioneering computer scientists at the time theorized that it might be possible to extend basic computer programming concepts using logic and reasoning to develop machines capable of “thinking” like humans. Over time, the definition and goals of AI have evolved. Some theorists argued for a narrower focus on developing computing systems able to efficiently solve problems, while others aimed for a closer replication of human intelligence. Today, AI encompasses a diverse set of techniques used to enable intelligent behavior in machines. Core disciplines that contribute to modern AI research include computer science, mathematics, statistics, linguistics, psychology and cognitive science, and neuroscience. Significant AI approaches used today involve statistical classification models, machine learning, and natural language processing. Classification methods are widely applicable to problems in various domains like healthcare, such as informing diagnostic or treatment decisions based on patterns in data. Dean and Goldreich, 1998, define ML as an approach through which a computer has to learn a model by itself from the data provided but no specification on the sort of model is provided to the computer. They can then predict values for things that are different from the values used in training the models. NLP looks at two interrelated concerns, the task of training computers to understand human languages and the fact that since natural languages are so complex, they lend themselves very well to serving a number of very useful goals when used by computers.

面向医疗系统的区块链的可搜索加密方案

在云计算作为辅助的电子医疗系统中,患者的电子医疗记录(Electronic Healthcare Records,EHRs)通常会外包给云服务器提供商(Cloud Server Provider,CSP),其中EHRs一般会以加密的形式上传到云服务器,再通过可搜索加密方案进行搜索.然而,由于过度依赖于被认为可完全信任的中心化服务器,现有的大多数可搜索加密方案仍面临着严重的安全问题.论文提出了一个面向医疗系统的区块链的可搜索加密方案,它不仅可以确保EHRs的安全,还可以提高存储在云服务器上的密码文本的搜索效率.在方案中,患者可以利用智能合约构建自动执行与自动查找的算法,这使医生收到可信的、正确的搜索结果.同时,方案采用了基于关键词转换的高效的模糊多关键词可搜索加密,优化EHRs的提取方式进而减少计算开销.此外,方案做了安全性分析和性能评估,证明方案的有效性和安全性.

Unidirectional Identity-Based Proxy Re-Signature with Key Insulation in EHR Sharing System

The introduction of the electronic medical record(EHR)sharing system has made a great contribution to the management and sharing of healthcare data.Considering referral treatment for patients,the original signature needs to be converted into a re-signature that can be verified by the new organization.Proxy re-signature(PRS)can be applied to this scenario so that authenticity and nonrepudiation can still be insured for data.Unfortunately,the existing PRS schemes cannot realize forward and backward security.Therefore,this paper proposes the first PRS scheme that can provide key-insulated property,which can guarantee both the forward and backward security of the key.Although the leakage of the private key occurs at a certain moment,the forward and backward key will not be attacked.Thus,the purpose of key insulation is implemented.What’s more,it can update different corresponding private keys in infinite time periods without changing the identity information of the user as the public key.Besides,the unforgeability of our scheme is proved based on the extended Computational Diffie-Hellman assumption in the random oracle model.Finally,the experimental simulation demonstrates that our scheme is feasible and in possession of promising properties.

Earlier IV Fluid and Antibiotic Administration with an ED Electronic Sepsis Screening Tool

We set out to overcome barriers previously shown to impede sepsis therapy. Application of a universally standardized therapy model is an ongoing controversy. By taking advantage of the novel and adaptable aspects of a new technology, we predict that the introduction of an electronic health record based sepsis identification tool in the emergency department will aid clinicians in earlier implementation of sepsis directed therapy, namely intravenous fluids and antibiotics. A retrospective cohort study of 3,076 patients with the diagnosis of sepsis was performed. Patient charts were identified for this study who met the criteria of： _〉 18 years old; emergency department evaluation; ICD-9 code of sepsis, severe sepsis, or septic shock. Data was divided into two treatment groups, pre- and post-best practice advisory （BPA） sepsis identification tool. Our primary outcome was time to intravenous fluids and time to antibiotics administration. The secondary outcome of in-patient all-cause mortality was measured. 1,266 patients were treated prior to, and 1,810 treated after, the BPA implementation with a decrease in time to intravenous fluids from 34% to 49.9% of patient receiving treatment in the first 60 min of emergency department arrival （difference of 15.9%; P 〈 0.05）. The time to administration of antibiotics in the first 180 min of arrival improved from 40.3% to 56.8% （difference of 16.5%; P 〈 0.05）. Secondarily, we found that in-patient mortality improved from 10.5% to 7.5%, pre- and post BPA respectively （difference of 3%; P 〈 0.05）. Our study has demonstrated that the implementation of an active electronic health record screen tool that alerts clinicians to the possibility of sepsis may improve the time to initiate fluid blouses and antibiotics, and may lead to improved outcomes.

EHR Technology： Improvement Review of a Small Rural Hospital

The focus of this study was to examine the technology improvements in a small rural hospital preparing to implement the first two stages of Health Information Technology for Economic and Clinical Health （HITECH） [ 1 ] in their organization. The existing hospital organization＇s health information technology （HIT） is on a continuum between a traditional system and one that can support evidence-based clinical decisions. A methodology based on hierarchy and experience, is routine and relies upon trial, and error is a traditional approach [2]. Prior experience with Electronic Health Records/Health Information Management Systems （EHR/HIMS） improvements in this hospital lacked a systematic evidence-based approach leading to inoperability and security concerns. Future improvements include adoption of nationally recognized standards for HIT protocols and planning incorporates a process to test improvements and upgrades with feedback from end-users prior to initiating full scale operations.

The development and impact of adopting electronic health records in the United States:A brief overview and implications for nursing education

1|DEVELOPMENT AND ADOPTION OF EHR IN THE UNITED STATES At present,health-care systems in the United States face enormous challenges in providing quality care,characterized by safe,effective,efficient,patientcentered,timely,and equitable care while containing health-care costs[1,2].To understand and address patients'increasingly complicated health-care needs,we need safe access to quality information that is characterized by integrity,reliability,and accuracy[3],and establish mutually beneficial relationships among a multidisciplinary team of professionals[4].Traditional paper-based clinical workflow produces many issues such as illegible handwriting,inconvenient access,the possibility of computational prescribing errors,inadequate patient hand-offs,and drug administration errors.These problems can lead to medical errors,omissions,and duplications and,ultimately,poor patient outcomes and compromised quality of care[2].

结构化电子病历数据录入方法

以HL7 CDA R2标准作为临床信息的结构化表达方式,提出了一种兼容标准术语的结构化录入(SDE)方法,用来解决由于标准术语的概念划分较粗,不足以通过标准术语编码的结构化内容重建自然语言满足临床日常信息交换需求的问题.该方法抛弃传统的通过标准化结构化结果重建叙述性内容的模式,采用同步生成叙述性内容和标准化结构化内容的模式,因而叙述性内容的生成不受限于结构化内容标准术语的概念划分,从而实现了在结构化数据录入中应用标准术语满足计算机可处理的同时满足临床日常工作对于自然语言信息的人工阅读需要.该方法为标准化结构化电子病历信息模型的数据获取兼容叙述性病历提供了一种新的解决思路.

基于联盟链的电子健康记录隐私保护和共享

医院正在逐渐采用电子健康记录(EHR)的方式去记录患者的医疗信息。然而,医疗数据的隐私性和EHR标准的差异化阻碍了医疗数据在病人和医院之间的共享。因此,针对隐私信息泄露和难于共享的问题,提出了一个基于联盟链的隐私保护数据共享模型。此外,基于匿名算法提出了(p,α,k)匿名隐私算法,能够解决EHR隐私信息泄露的问题。通过理论分析和实验证明,提出的基于联盟链和(p,α,k)隐私匿名算法模型能够在保护数据隐私的前提下,实现病人和医院之间的数据安全共享。对比前人的模型,该模型具有所需节点少、减少主链压力、容错性强和病人对EHR完全控制等优势。
