- Health Level Seven (HL7) is a widely recognized standard for the exchange, integration, sharing, and retrieval of electronic health information. The HL7 standard typically encodes a wide variety of records that are used in healthcare settings, including:
- Patient demographic information, such as name, age, gender, and contact information.
- Clinical observations and assessments, such as vital signs, laboratory results, and imaging reports.
- Medication and treatment information, such as prescriptions, dosage, and frequency of administration.
- Medical device data, such as data from monitors, sensors, and other medical devices used to monitor and treat patients.
- Diagnostic information, such as the results of diagnostic tests and procedures.
- Care team information, such as the names and roles of healthcare providers involved in the patient's care.
- Health plan information, such as insurance coverage and eligibility information.
- Administrative and financial information, such as billing and payment records.
- Public health reporting data, such as data related to the incidence and spread of infectious diseases and other public health concerns.
- Quality improvement data, such as data related to patient safety and clinical outcomes.
- Overall, the HL7 standard is designed to facilitate the exchange and integration of a wide variety of healthcare records, enabling healthcare providers to share and access important patient data and improve the quality and safety of patient care.

- Health Level Seven or HL7 refers to a set of international standards for transfer of clinical and administrative data between software applications used by various healthcare providers. These standards focus on the application layer, which is "layer 7" in the OSI model. The HL7 standards are produced by Health Level Seven International, an international standards organization, and are adopted by other standards issuing bodies such as American National Standards Institute and International Organization for Standardization.
Hospitals and other healthcare provider organizations typically have many different computer systems used for everything from billing records to patient tracking. All of these systems should communicate with each other (or "interface") when they receive new information, or when they wish to retrieve information, but not all do so.
HL7 International specifies a number of flexible standards, guidelines, and methodologies by which various healthcare systems can communicate with each other. Such guidelines or data standards are a set of rules that allow information to be shared and processed in a uniform and consistent manner. These data standards are meant to allow healthcare organizations to easily share clinical information. Theoretically, this ability to exchange information should help to minimize the tendency for medical care to be geographically isolated and highly variable. HL7 International considers the following standards to be its primary standards – those standards that are most commonly used and implemented: * Version 2.x Messaging Standard – an interoperability specification for health and medical transactions * Version 3 Messaging Standard – an interoperability specification for health and medical transactions * Clinical Document Architecture (CDA) – an exchange model for clinical documents, based on HL7 Version 3
- Continuity of Care Document (CCD) – a US specification for the exchange of medical summaries, based on CDA.
- Structured Product Labeling (SPL) – the published information that accompanies a medicine, based on HL7 Version 3
- Clinical Context Object Workgroup (CCOW) – an interoperability specification for the visual integration of user applications
- Other HL7 standards/methodologies include:
- Fast Healthcare Interoperability Resources (FHIR) – a standard for the exchange of resources
- Arden Syntax – a grammar for representing medical conditions and recommendations as a Medical Logic Module (MLM)
- Claims Attachments – a Standard Healthcare Attachment to augment another healthcare transaction
- Functional Specification of Electronic Health Record (EHR) / Personal Health Record (PHR) systems – a standardized description of health and medical functions sought for or available in such software applications
- GELLO – a standard expression language used for clinical decision support

- ABSTRACT: We present the design and implementation of a Health Level-7 (HL7)-compliant web-based clinical patient records system (CPRS). HL7 is one of the leading standards for exchange of clinical and administrative data among healthcare information systems. Since the passage of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) by US government, the security of electronic medical clinical records systems is of paramount importance. HIPAA requires that various technical, physical and administrative security measures be combined to protect the privacy, integrity, and availability of patients' clinical records. The HL7 standard for clinical documents, Clinical Document Architecture (CDA), incorporates the HIPAA guidelines. Our CPRS data schema is derived from CDA that makes it naturally in compliance with the HIPAA guidelines. CPRS provides a unique web based interface for the caregivers to browse and edit universal patient records (UPR) of their patients. To our knowledge, CPRS is one of the first applications that have implemented an HL7-compliant UPR. Using CPRS caregivers can access and edit the clinical documents of their patients from anywhere in the world.
