Semantic interoperability in e_health for improved healthcare

Sharing of health data between independent organizations, each using customized Electronic Health Records (EHR) management systems or Healthcare Information System (HIS) encompasses major concerns. It requires an integrated interoperable environment or interface commonly understood by end-users of healthcare domain. The sheer number of systems, standards, procedures and system developers seriously hinders interoperability. Developers need to adhere to the standards while designing such system. Developing standardized interfaces would enable seamless communication and transfer of required EHR between disparate systems. The paper after giving a detailed overview of interoperability identifies the challenges to Health Informatics data-exchange in interoperable environment and recommends some viable solutions in this direction. This paper provides a glance at different approaches of designing interoperable models and illustrates the healthcare models designed on such approaches. The study also includes available set of vocabularies, formats and standards specifically designed for the purpose. Considering the Health environment, protecting the confidentiality and illegal disclosure during transfer of EHR between organizations, is a serious concern. Vendors incorporate customized and vendor-dependent security attributes while designing the application, resulting in major challenge of securely sharing of data. The paper includes available security controls and gaps accruing due to interoperability and recommends the need of robust security control improving accessibility and availability of EHR at the required place by the authorized user.

Progress of health information system (HIS) in recent years has made significant impact on both developed and developing countries. HIS has played a very important role in the hospital. Construction and employment of HIS can improve the efficiency and quality of healthcare work. But the development of HIS has some problems inherent in them such as non-standard hospital management, poor standardization, and lack of interoperable software development. As a result, HIS run is not able to share medical information and therefore, can't meet the needs of reform in healthcare system delivery. In the future, for the sake of medical information sharing, teleconsulation, hospital efficiency enhancement, all the independent systems will realize interoperability. This paper however, seeks to analyze and address factors militating against interoperability in software systems the healthcare domain and recommends the adoption of service oriented architecture (SOA) within the domain.

As India is one of the fastest developing countries in the world, it is important to improve the quality of our health maintenance management and preventive medical care to extend healthy life expectancy. Today's scenario for health care in Indian e governance is in the limit of contacting 75 hospitals of the ISRO Telemedicine network only. Whilst this is currently working best of it, the limitation of this can be retarded by introducing the health care web services to each individual of the country. We believe advanced implementation of Information and Communications Technologies (ICT) may improve the medical services and health maintenance management. As medical science is fast developing and information resource is pouring in, there is urgent need for dissemination knowledge by interlinking primary, secondary and tertiary level health centers by ICT applications. This will help health personal to deliver high quality services. Moreover, IT systems have been built to support different work flows in the health sector, but the systems are rarely connected and have become islands of data. From 2006 onwards corporate IT giants are experimenting for ICT application in health sector both in Government and private hospitals. In this paper, we discuss the potentialities and expansibility of the XML Web Services based on the Adaptive Collaboration (AC) which can be aggregated by the Indian e governance system as a health care web services. We would like to present ways of improving health maintenance service and regional medical services. In order to realize better health maintenance and prevention of disease, we would like to prove that incorporating medicine, life, and work through the XML Web Services is highly effective. The developed system is using data agent concept in transferring the format of information from different medical database systems to be an international standard format of metadata known as HL7 v3.0 using XML based cloud services called the Medical Cloud system which can take advantage of the Indian cloud revolution.

E-health plays a crucial role in E-government by proposing healthcare services based on information technology. However, the way to administer these services by using E-health solutions is one of the challenging issues. One of these significant challenges is how one integrates heterogeneous healthcare information of the different point of care systems. This paper introduces the Iranian integrated care electronic health record using the information gathered from several point-of-care systems in healthcare enterprises in Iran. This service-oriented architecture has a remarkable characteristic – its accessibility to medical knowledge and medical concepts through archetypes and ontology, respectively. The Ministry of Health and Medical Education of the Islamic Republic of Iran has designed and implemented this national architecture.

Integrated care approach and the broader view on a patient's care is something that today's healthcare systems thrive for. Medical information collected from many disparate sources, accessed by authorized users through Electronic healthcare record (EHR) is enabling technology behind. This article gives overview of different interoperability aspects related to data exchange and maps it to usual healthcare business processes. It also comments HL7 CDA being one of today's widely used standards for clinical documents exchange. One concrete approach to Personal Healthcare Record (PHR) to EHR integration using HL7 Continuity of Care Document (CCD) is described.

The main objective of this research study is the development of conceptual framework for the exchanging of patient records located in different hospitals all over the Kingdom of Saudi Arabia. The proposed framework is aimed to improve the way of retrieving the patient medical records from different health information system. The proposed architecture, designed to highlight the method by which data should be searched and retrieved efficiently from the different health information systems. Our system design is based on Cloud Computing Service Oriented Architecture. These medical systems storing the medical information records including: demographics medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal stats like age and weight. All of these medical records are identified by National ID number. These systems will be utilized by the web services XML based approach. The patients will use their ID number to send request for their medical informatics and the web service will analyze the patient records and send the result back to the patient. The main contribution of this study is to provide a data exchange model of patient records, this model used to decrease the cost and time of patients, and help patients to get its medical records information from any location by using the Web.

We have Aadhar card, Pan card, driving license like identity proofs for our day-today transactions, but we have a major missing feature that is our health card, which manages our day-today health history like disease, allergy etc. And the same card is used everywhere in private and public hospitals and clinics, medical stores, laboratories to track your health-related data, which the concerned entity will enter the system. We aim to gather only health related data, so we are not aiming to involve any economical transaction into the system. We are proposing an Environment where all the Medical Reports will be managed by our system and provided to the user through our portal. Managing all Reports, Prescription, Medical History arranged in Time Frame format so it can be accessed easily whenever needed. Only doctors and authorized hospital staff can insert the health reports in the system. Patients can only access the reports in read only mode. This will give Real time information to health authorities so that action can be taken at the right time and thus it can save many people from becoming victims of some viral disease. We aim to gather only health related data, so we are not aiming to involve any economical transaction into the system. The health card will store all the scans, x-rays, prescriptions and other health related documents of a patient. It will also include details of patients' long-term conditions, allergies, etc. The health records can only be edited by authorized staff of a hospital and care system involved in the patient's direct care. This health card will make it easier for doctors to operate under emergency conditions.

New technologies have improved the ability of electronically storing, transferring and sharing medical data; they also create serious questions about who has access to this cross-media content and how it is protected and distributed. Our aim is to support healthcare professionals in this changing environment, by providing a set of software tools that help reducing the time and associated costs to collect the information and knowledge required, and in making the best use of it for a more informed decision making (diagnoses, therapies, protocols). An appropriate and consistent level of information security consists of protecting information both in written, spoken, electronically recorded, or printed form from accidental or malicious modification, destruction, or disclosure by applying the strictest requirements for data security and privacy and complying with ethical standards. By Doc@Hand project we experiment the distribution of computer-based patient record, natural language queries and the contained knowledge in a secured way.

Healthcare data interchange standards are important aspect for achieving interoperability for health information exchanges. However, there is a big void in literature that could clearly differentiate among available healthcare standards with a motive of necessity of upgrading to new standards resulting in cost effective and efficient standard to support interoperability for a National Healthcare Information System (NHIS). These standards act as key to achieve semantic interoperability in health sector to ensure patient information availability anytime and right at the point of care. In this paper we present a study and a comparative review of healthcare interoperability standards as a means of meeting the desired semantic interoperability and integration of stovepipe applications of varied Electronic Medical Records in a heterogeneous environment and achieving efficient Electronic Health Record. This study gives a flash tour on healthcare standards in terms of their scope, advantages, level of interoperability support and challenges. The paper also shows how the standards can be upgraded to next level by a possible inclusion of web services concept.

Information exchange, enabled by computable interoperability, is the key to many of the initiatives underway including the development of Regional Health Information Exchanges, Regional Health Information Organizations, and the National Health Information Network. These initiatives must include public health as a full partner in the emerging transformation of our nation's healthcare system through the adoption and use of information technology. An electronic health record - public health (EHR-PH)system prototype was developed to demonstrate the feasibility of electronic data transfer from a health care provider, i.e. hospital or ambulatory care settings, to multiple customized public health systems which include a Newborn Metabolic Screening Registry, a Newborn Hearing Screening Registry, an Immunization Registry and a Communicable Disease Registry, using HL7 messaging standards. Our EHR-PH system prototype can be considered a distributed EHR-based RHIE/RHIO model - a principal ...
