Automatic Import of Patient Data, Including Medical Results, Diagnoses, and Administrative Data

HL7 is a worldwide established standard for exchanging medical data between different software systems. The cato® HL7 interface uses this standard to easily connect cato® to the patient administration system, the laboratory system, or other IT systems in the hospital.

cato®-related data are directly imported into the cato® database; no manual entry of the patient master data or of other values, as for example medical results or diagnoses, is necessary.

In addition, both physician and pharmacist automatically have access to the latest medical results of the patient and can therefore utilize cato®'s automated therapy monitoring features to full extent.


The cato® HL7 interface can be used in two different

As server-side Windows Service ("cato® HL7 Service"), it automatically receives HL7 messages and saves the patient data into the cato® database. The sender system controls patients to be sent to cato®.

With the client-side version of the cato® HL7 interface ("cato® HL7 Query"), it is integrated into the cato® client software and “pulls” patient data actively. Only if a patient is required in cato®, a data exchange takes place via HL7. A precondition for this is the support of HL7 Query Messages ("QRY") by the respective patient administration system.

A combination of both versions for the specific request of patients and the import of laboratory values is also possible.

The interface was designed for the HL7 standard version 2.3.x. If you are using another version of HL7 please contact Cato Software Solutions for information about compatibilities.









The cato® HL7 interface is easy to install and to configure. All important messages and event types are supported.

Due to a number of configuration options, the interface software is highly flexible and can be adapted to the respective system environment by an Administrator. Communication is either file-based or takes place via TCP/IP. The interface can be linked to several systems simultaneously (e.g. KIS and the laboratory system) and can therefore receive messages from different systems at the same time.
A state-of-the-art user interface with detailed informationor error messages facilitates comfortable configuration and monitoring of the interface.
