Electronic Health Record (EHR) is the heart element of any e-health system, which aims at improving the quality and efficiency of healthcare through the use of information and communication technologies. The sensitivity of the data contained in the health record poses a great challenge to security. In this paper we propose a security architecture for EHR systems that are conform with IHE profil...

The purpose of a Referent Tracking System (RTS) is to manage the representation of particulars in a database and to share this information with Electronic Health Record (EHR) systems. We describe how an implementation of such a RTS can be integrated in an EHR system using middleware technology based on web services. We describe the functional and technical requirements of such an approach and d...

One of the prevalent applications implicated temporal information is Electronic Health Record (EHR) systems. The representation of temporal aspects offers a particular challenge. We need to define a good set of features that are able to represent well the different temporal aspects required in EHR, where data are temporal in nature. This paper focuses on the identification and modeling of tempo...

Abstract Patient’s vital data will have an important role in future medicine. Best way to store this is the patient’s electronic health record (EHR) a structured form. In Germany, several laws, regulations and standards must be considered record, like SGB V, DIGAV Medical Information Objects. near future, it possible upload self-recorded German EHR special smartphone apps. It also automatically...

Electronic health record (EHR) advocates argue that EHRs lead to reduced errors and reduced costs. Many reports suggest otherwise. The EHR often leads to higher billings and declines in provider productivity with no change in provider-to-patient ratios. Error reduction is inconsistent and has yet to be linked to savings or malpractice premiums. As interest in patient-centeredness, shared decisi...

Employing a machine learning approach we predict, up to 24 hours prior, a diagnosis of severe sepsis. Strongly predictive models are possible that use only text reports from the Electronic Health Record (EHR), and omit structured numerical data. Unstructured text alone gives slightly better performance than structured data alone, and the combination further improves performance. We also discuss...

PROBLEM Although electronic communication of clinical data between various actors in the healthcare domain seems crucial for a cost-effective patient treatment, it is mostly restricted to paper based documents. In order to meet the growing need for improved data communication, it is necessary to overcome the barriers of software heterogeneity and lack of standards, especially in cross-instituti...

For purposes of this article, Healthcare Information and Management Systems Society’s (HIMSS’) definition of an electronic health record (EHR) is used. The EHR represents the ability to easily share medical information among stakeholders and to have a patient’s information follow him or her through the various modalities of care engaged by that individual. Any hospital with the means to do so c...

OBJECTIVES The aim of this study was to examine open-source electronic health record (EHR) software to determine their level of functionalities according to the International Organization for Standardization (ISO) standards. METHODS ISO standards were used as a guideline to determine and describe the reference architecture and functionalities of a standard electronic health record system as w...
