Electronic health record

Electronic health record (EHR) is a digital version of a patient's paper-based medical record, which is maintained by healthcare providers such as Mayo Clinic, Cleveland Clinic, and Johns Hopkins Hospital. EHRs are designed to improve the quality and efficiency of patient care by providing healthcare professionals like Nurses, Physicians, and Pharmacists with access to accurate and up-to-date information about a patient's medical history, including Medications prescribed by Doctors and Surgeons. EHRs are used by Hospitals, Clinics, and Private practices like Kaiser Permanente and UnitedHealth Group. The use of EHRs has been promoted by Health information technology initiatives, such as those implemented by Centers for Medicare and Medicaid Services and Office of the National Coordinator for Health Information Technology.

Introduction

The use of EHRs has become increasingly widespread in recent years, with many Healthcare systems like National Health Service and Veterans Health Administration adopting them as a way to improve Patient outcomes and reduce Medical errors. EHRs are used by Healthcare providers like American Medical Association and American Hospital Association to store and manage patient information, including Medical history, Medications, and Test results from Laboratories like Quest Diagnostics and LabCorp. EHRs can also be used to facilitate Communication between Healthcare providers and Patients, such as through Patient portals like MyChart and FollowMyHealth. Many Health information exchanges like Health Information Trust Alliance and National Alliance for Health Information Technology have been established to facilitate the sharing of EHRs between different Healthcare providers.

History

The concept of EHRs has been around for several decades, with early systems being developed in the 1960s and 1970s by Pioneers like Larry Weed and Octo Barnett. However, it wasn't until the 1990s and 2000s that EHRs began to gain widespread acceptance, with the introduction of Standards like HL7 and DICOM by Organizations like Health Level Seven International and National Electrical Manufacturers Association. The Health Information Technology for Economic and Clinical Health Act (HITECH) was passed in 2009, providing Incentives for Healthcare providers like Hospitals and Physician practices to adopt EHRs. Many Countries like United States, Canada, and Australia have implemented National health IT strategies to promote the adoption of EHRs.

Components

EHRs typically consist of several key Components, including Demographic information like Patient name and Date of birth, Medical history like Allergies and Medications, and Clinical data like Vital signs and Test results from Devices like Electrocardiogram and Computerized tomography. EHRs may also include Orders like Medication orders and Laboratory orders, as well as Results like Laboratory results and Imaging results from Imaging centers like Radiology and Magnetic resonance imaging. Many EHRs also include Decision support tools like Clinical decision support systems and Medication management systems to help Healthcare providers make informed decisions. Interoperability is a critical component of EHRs, allowing different Systems to communicate with each other, such as Epic Systems and Cerner Corporation.

Advantages

The use of EHRs has several Advantages, including improved Patient safety and reduced Medical errors, like those reported by Institute of Medicine and Agency for Healthcare Research and Quality. EHRs can also help to improve Clinical decision-making by providing Healthcare providers with access to accurate and up-to-date information, like Guidelines from American Heart Association and American Diabetes Association. Additionally, EHRs can help to reduce Healthcare costs by reducing the need for Duplicate tests and Procedures, as reported by Centers for Medicare and Medicaid Services and Congressional Budget Office. Many Studies like those published in Journal of the American Medical Association and New England Journal of Medicine have shown that EHRs can also improve Patient engagement and Satisfaction.

Implementation

The Implementation of EHRs can be a complex and challenging process, requiring significant Investment in Technology and Training for Healthcare providers like Nurses and Physicians. Many Hospitals and Health systems like Kaiser Permanente and Geisinger Health System have implemented EHRs, with the help of Consultants like Deloitte and PricewaterhouseCoopers. The Office of the National Coordinator for Health Information Technology has provided Guidance and Support for Healthcare providers implementing EHRs, including Meaningful use Incentives and Certification programs like those offered by Drummond Group and InfoGard Laboratories.

The Security and privacy of EHRs is a critical concern, with Healthcare providers and Patients relying on Systems to protect sensitive Information like Protected health information. Many Laws and Regulations like Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR) have been put in place to protect the Security and privacy of EHRs, with Enforcement by Agencies like Office for Civil Rights and Federal Trade Commission. Encryption and Access controls are commonly used to protect EHRs, like those implemented by Epic Systems and Cerner Corporation. Audits and Monitoring are also used to detect and prevent Security breaches, like those reported by Identity Theft Resource Center and Ponemon Institute. Patients have the right to access their EHRs, as guaranteed by Laws like HIPAA and Patient Safety and Quality Improvement Act. Category:Health informatics
