Medical device connectivity

Medical device connectivity is the establishment and maintenance of a connection through which data is transferred between a medical device, such as a patient monitor, and an information system. The term is used interchangeably with biomedical device connectivity or biomedical device integration. By eliminating the need for manual data entry, potential benefits include faster and more frequent data updates, diminished human error, and improved workflow efficiency.

Medical devices may be connected on wireless and wired networks. Wireless networks, including Wi-Fi, Wireless Medical Telemetry Service, and Bluetooth, provide more ubiquitous coverage of connectivity, allowing uninterrupted monitoring of patients in transit. Wired networks are fast, stable, and highly available. Wired networks are usually more costly to install at first and require ongoing costs for maintenance, but allow connectivity of the organization in a closed environment.

Adherence to Standards ensures interoperability within a network of medical devices. In most cases, the clinical environment is heterogenous; devices are supplied by a variety of vendors, allowing for different technologies to be utilized. Achieving interoperability can be difficult, as data format and encryption varies among vendors and models. The following standards enable interoperability between connected medical device.

Regulatory organizations and industrial associations, such as Integrating the Healthcare Enterprise (IHE) initiative and Continua Health Alliance, are working towards standardized vendor-neutral device integration systems. The IHE provides a single set of internationally harmonized medical device informatics and interoperability standards as a unitary reference point for the industry. The IHE collaborates with Continua Health Alliance regarding data exchange protocol and device specializations.

The IHE Patient Care Device (PCD) Technical Framework Volumes 1-3 defines the established standards profiles, such as the integration, transaction and semantic content profiles respectively for complete, enterprise-wide integration and interoperability of health information systems. Several profiles have applications in medical device connectivity including the following:

Hospitals have many different makes and models of medical devices. Each department has different types of devices, and rarely does an entire hospital run the same brand device. Because of the large number of devices, and the varying formats that data is exchanged (RS-232, HL7, Bluetooth, WiFi), Medical Device Integration software has become a critical component to integrating this vital patient data. Software such as Picis Hawkeye connects with virtually any device via HL7, Serial (RS-232), Bluetooth, WiFi, etc., and shares this data to any other software platform across a hospital network. This allows hospitals to continue to use their older devices, in a more modern network.
