Rology - HIS Integration
Bridging DICOM and HL7 for Superior Medical Imaging
By: Mohamed Hammam - Medical Liaison at Rology
The integration Rology offers with Health Information Systems (HIS) – an FDA Cleared Feature – between HL7 and DICOM is more than a technical advancement; it’s a game-changer for medical imaging where patient records, clinical data, and imaging studies flow effortlessly between systems, enabling clinicians to make well-informed decisions with unprecedented speed and precision. By harmonizing these standards, healthcare providers can enhance patient outcomes, streamline workflows, and reduce errors.
This integration not only bridges the gap between clinical and imaging data but also paves the way for a future where healthcare is more connected, efficient, and patient-centric. Before explaining how the integration works, you need to know about the Health information systems HIS.
Health information systems (HIS)
A health information system (HIS) is an information system for processing data, information, and knowledge in healthcare environments. It can be defined as an integrated effort to collect, process, report, and use health information and knowledge to influence policy-making, program action, and research. HIS can be described in three layers:
1. Domain Layer: This layer specifies what entities (like customers, products, etc.) exist and what they do. This layer defines entities like patients, doctors, and medical equipment. For instance, a patient can book appointments, a doctor can diagnose illnesses, and an X-ray machine captures images.
2. Logical Tool Layer: This layer outlines the software components and how they work together. It’s like a blueprint showing how different parts of the software interact to perform tasks. For example, appointment scheduling software communicates with patient record software, ensuring that when a patient books an appointment, the doctor’s schedule updates, and a confirmation email is sent.
3. Physical Tool Layer: This layer deals with the actual physical setup, like servers and databases, where the application runs. It’s about the tangible infrastructure supporting the system For instance, patient data is stored on hospital servers, allowing doctors to access medical histories from these secure databases. [1-2].
HL7
Health Level Seven (HL7) is an international set of standards for the exchange, integration, sharing, and retrieval of electronic health information. Developed by Health Level Seven International, HL7 provides a framework to support the management, delivery, and evaluation of health services. It aims to enhance interoperability between healthcare information systems by providing a common data exchange language through prebuilt messages, allowing various healthcare systems to communicate effectively [3-4].
DICOM
Digital Imaging and Communications in Medicine (DICOM) is a global standard for handling, storing, printing, and transmitting information in medical imaging. It includes the definition of file formats and a network communications protocol. DICOM enables the integration of scanners, servers, workstations, printers, and network hardware from multiple manufacturers into radiology systems such as Rology Teleradiology Platform [3-5].
How Does the DICOM/HL7 Integration Work?
Integrating HL7 and DICOM involves creating a seamless interface that allows patient information and medical imaging data to be shared and accessed across different systems. Here’s how it works:
- Patient Data Management: HL7 messages manage patient demographics, scheduling, and clinical data. When a patient undergoes an imaging procedure, HL7 messages can send relevant patient information to the imaging system.
- Image Acquisition and Storage: The imaging system, using DICOM standards, captures and stores the medical images. These images are tagged with metadata, including patient information, ensuring they are linked to the correct patient.
- Data Exchange and Communication: HL7 messages can trigger imaging procedures and notify other systems when images are available. DICOM files are then stored and made accessible to other healthcare systems.
- Workflow Coordination: Integrating HL7 and DICOM helps coordinate workflows by ensuring that patient information and imaging data are synchronized. For instance, an HL7 message can schedule an imaging procedure, and once the images are taken, a DICOM message can update the patient’s record in the electronic health record (EHR) system [3-5].
The Integration of HL7 and DICOM is Crucial for Several Reasons:
- Enhanced Patient Care
- Operational Efficiency
- Interoperability
- Data Accuracy
The integration of HL7 and DICOM represents a significant step forward in the realm of medical imaging and healthcare IT. It not only improves the quality of patient care but also enhances the efficiency and reliability of healthcare services, making it a cornerstone of modern medical practice [1-3].
