Health informatics is information engineering applied to the field of health care, essentially the management and use of patient health care information. It is a multidisciplinary field that uses health information technology (HIT) to improve health care via any combination of higher quality, higher efficiency, and new opportunities. The disciplines involved include information science, computer science, social science, behavioral science, management science, and others. The United States National Library of Medicine (NLM) defines health informatics as "the interdisciplinary study of the design, development, adoption and application of IT-based innovations in health care services delivery, management and planning". It deals with the resources, devices, and methods required to optimize the acquisition, storage, retrieval, and use of information in health and bio-medicine. Health informatics tools include computers, clinical guidelines, formal medical terminologies, and information and communication systems, among others. It is applied to the areas of nursing, clinical medicine, dentistry, pharmacy, public health, occupational therapy, physical therapy, biomedical research, and alternative medicine, all of which are designed to improve the overall of effectiveness of patient care delivery by ensuring that the data generated is of a high quality.
A hospital information system (HIS) is an element of health informatics that focuses mainly on the administrational needs of hospitals. In many implementations, an HIS is a comprehensive, integrated information system designed to manage all the aspects of a hospital's operation, such as medical, administrative, financial, and legal issues and the corresponding processing of services. Hospital information system is also known as hospital management software (HMS) or hospital management system.
An electronic health record (EHR) is the systematized collection of patient and population electronically-stored health information in a digital format. These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHRs may include a range of data, including demographics, medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal statistics like age and weight, and billing information.
Medical practice management software (PMS) is a category of healthcare software that deals with the day-to-day operations of a medical practice including veterinarians. Such software frequently allows users to capture patient demographics, schedule appointments, maintain lists of insurance payors, perform billing tasks, and generate reports.
A personal health record (PHR) is a health record where health data and other information related to the care of a patient is maintained by the patient. This stands in contrast to the more widely used electronic medical record, which is operated by institutions and contains data entered by clinicians to support insurance claims. The intention of a PHR is to provide a complete and accurate summary of an individual's medical history which is accessible online. The health data on a PHR might include patient-reported outcome data, lab results, and data from devices such as wireless electronic weighing scales or from a smartphone.
OpenEMR is a medical practice management software which also supports Electronic Medical Records (EMR). It is ONC Complete Ambulatory EHR certified and it features fully integrated electronic medical records, practice management for a medical practice, scheduling, and electronic billing.
OSCAR McMaster is a web-based electronic medical record (EMR) system initially developed for academic primary care clinics. It has grown into a comprehensive EMR and billing system used by many doctor's offices and private medical clinics in Canada and other parts of the world. The name is derived from where it was created and an acronym; OSCAR stands for Open Source Clinical Application and Resource and McMaster refers to McMaster University, where it was developed. It enables the delivery of evidence resources at the point of care.
Patient portals are healthcare-related online applications that allow patients to interact and communicate with their healthcare providers, such as physicians and hospitals. Typically, portal services are available on the Internet at all hours of the day and night. Some patient portal applications exist as stand-alone web sites and sell their services to healthcare providers. Other portal applications are integrated into the existing web site of a healthcare provider. Still others are modules added onto an existing electronic medical record (EMR) system. What all of these services share is the ability of patients to interact with their medical information via the Internet. Currently, the lines between an EMR, a personal health record, and a patient portal are blurring. For example, Intuit Health and Microsoft HealthVault describe themselves as personal health records (PHRs), but they can interface with EMRs and communicate through the Continuity of Care Record standard, displaying patient data on the Internet so it can be viewed through a patient portal.
ClearHealth is an open-source practice management (PM) and electronic medical records (EMR/EHR/PHR) system available under the GNU General Public License.
The Zambia Electronic Perinatal Record System (ZEPRS) is an Electronic Medical Record (EMR) system used by public obstetric clinics and a hospital in Lusaka, Zambia.
Health information technology (HIT) is information technology applied to health and health care. It supports health information management across computerized systems and the secure exchange of health information between consumers, providers, payers, and quality monitors. Based on an often-cited 2008 report on a small series of studies conducted at four sites that provide ambulatory care – three U.S. medical centers and one in the Netherlands – the use of electronic health records (EHRs) was viewed as the most promising tool for improving the overall quality, safety and efficiency of the health delivery system. According to a 2006 report by the Agency for Healthcare Research and Quality, broad and consistent utilization of HIT will:
The Veterans Information Systems and Technology Architecture (VISTA) is the nationwide veterans clinical and business information system of the U.S. Department of Veterans Affairs. VISTA consists of 180 applications for clinical, financial, and administrative functions all integrated within a single database, providing single, authoritative source of data for all veteran-related care and services. The U.S. Congress mandates the VA keep the veterans health record in a single, authoritative, lifelong database, which is VISTA.
NextGen Healthcare is an American software and services company headquartered in Irvine, California, US. The company develops and sells electronic health record (EHR) software and practice management systems to the healthcare industry. NextGen Healthcare also provides population health, financial management, and clinical solutions for medical and dental practices. On September 7, 2018, Quality Systems Inc. changed its name to Nextgen Healthcare, Inc. and on September 10, their stock ticker symbol changed to NASDAQ: NXGN.
AHLTA is a global Electronic Health Record (EHR) system used by U.S. Department of Defense(DoD). It was implemented at Army, Navy and Air Force Military Treatment Facilities (MTF)around the world between January 2003 and January 2006. It is a services-wide medical and dental information management system. What made AHLTA unique was its implementation date, its Central Data Repository, its use in operational medicine and its global implementation. There is nothing like it in the private sector. (According to the DoD, “AHLTA” was never an acronym, but is rather the system's only name.)
Clinical point of care (POC) is the point in time when clinicians deliver healthcare products and services to patients at the time of care.
Digital health is the convergence of digital technologies with health, healthcare, living, and society to enhance the efficiency of healthcare delivery and make medicine more personalized and precise. The discipline involves the use of information and communication technologies to help address the health problems and challenges faced by people under treatment. These technologies include both hardware and software solutions and services, including telemedicine, web-based analysis, email, mobile phones and applications, text messages, wearable devices, and clinic or remote monitoring sensors. Generally, digital health is concerned about the development of interconnected health systems to improve the use of computational technologies, smart devices, computational analysis techniques, and communication media to aid healthcare professionals and their clients manage illnesses and health risks, as well as promote health and wellbeing.
Medical image sharing is the electronic exchange of medical images between hospitals, physicians and patients. Rather than using traditional media, such as a CD or DVD, and either shipping it out or having patients carry it with them, technology now allows for the sharing of these images using the cloud. The primary format for images is DICOM. Typically, non-image data such as reports may be attached in standard formats like PDF during the sending process. Additionally, there are standards in the industry, such as IHE Cross Enterprise Document Sharing for Imaging (XDS-I), for managing the sharing of documents between healthcare enterprises. A typical architecture involved in setup is a locally installed server, which sits behind the firewall, allowing secure transmissions with outside facilities. In 2009, the Radiological Society of North America launched the "Image Share" project, with the goal of giving patients control of their imaging histories by allowing them to manage these records as they would online banking or shopping.
Home health care software sometimes referred to as home care software or home health software falls under the broad category of health care information technology (HIT). HIT is “the application of information processing involving both computer hardware and software that deals with the storage, retrieval, sharing, and use of health care information, data, and knowledge for communication and decision making” Home health software is designed specifically for companies employing home health providers, as well as government entities who track payments to home health care providers.
The pharmacy management system, also known as the pharmacy information system, is a system that stores data and enables functionality that organizes and maintains the medication use process within pharmacies.
Federal and state governments, insurance companies and other large medical institutions are heavily promoting the adoption of electronic health records. The US Congress included a formula of both incentives and penalties for EMR/EHR adoption versus continued use of paper records as part of the Health Information Technology for Economic and Clinical Health (HITECH) Act, enacted as part of the, American Recovery and Reinvestment Act of 2009.
