This seamless exchange improves care coordination, enhances patient safety, and promotes more efficient healthcare delivery.
CommonWell Health Alliance: CommonWell Health Alliance is a non-profit organization that aims to promote health information exchange (HIE) and interoperability among various healthcare systems across the United States. It seeks to enable seamless data sharing between healthcare providers, allowing for improved patient care and enhanced efficiency in the healthcare system. By providing a framework for different electronic health record (EHR) systems to work together, CommonWell plays a vital role in advancing the accessibility and coordination of healthcare data.
De-identify data: De-identifying data refers to the process of removing or altering personal identifiers from a dataset so that individuals cannot be easily identified. This practice is essential in healthcare, particularly for ensuring patient privacy and compliance with regulations when sharing health information across systems or organizations. By de-identifying data, organizations can facilitate research and analysis without compromising individual confidentiality.
DICOM: DICOM, or Digital Imaging and Communications in Medicine, is a standard used for transmitting, storing, and sharing medical images and related information. It ensures interoperability between different imaging devices and healthcare systems, allowing healthcare providers to access and exchange medical images seamlessly, improving patient care and workflow efficiency.
Efficient care coordination: Efficient care coordination is the seamless management and integration of patient care activities across various healthcare settings and providers. This approach enhances communication, reduces redundancies, and ensures that patients receive timely and appropriate care, ultimately improving health outcomes. By utilizing health information exchange and interoperability, efficient care coordination facilitates the sharing of vital patient data, enabling healthcare teams to collaborate effectively and make informed decisions.
EHealth Exchange: eHealth Exchange is a nationwide health information exchange framework that enables secure sharing of electronic health information among healthcare providers, patients, and other stakeholders. This system enhances interoperability by allowing different electronic health record (EHR) systems to communicate, facilitating timely access to patient data and improving care coordination.
FHIR: FHIR, or Fast Healthcare Interoperability Resources, is a standard for exchanging healthcare information electronically. It provides a framework and set of resources that enable different health systems to share data in a consistent and efficient manner, promoting interoperability and enhancing health information exchange across diverse platforms.
Health Information Exchange (HIE): Health Information Exchange (HIE) refers to the electronic sharing of health-related information among organizations.
