CAFE System Development Project

Strategy

Implement the information infrastructure to enhance the scientific and economic clinical decision support.

Development of J2EE Based Hospital Information System (Physician Order Entry System ) with

• Alert and Reminder
• Proposal
• Summarization
• Clinical Practice Guideline

Establish Patient information central data repository

Project

CAFE (Clinician Assisting Front End for Physician Order Entry ) system has been designed and developed for University of Tsukuba Hospital.

CAFE is primary designed by Dr. Keisuke Nagase (University of Tsukuba) as a part of Medifact Project. It is developed with Sun Microsystems (Japan) Co. Ltd. JCTC and Nau Data Institute as joint research project with Dr Isao Nagasawa, Dr. Masanobu Umeda and their colleagues in Kyushu Institute of Technology.

Status

CAFE has been released partly on Jan. 2003 in University of Tsukuba Hospital. All domain except injection order entry has been released to operation.
First clinical knowledge will be released and implemented to operation on Dec 2003.

CAFE overview

CAFE is technically a front end for the physician order entry system. It is J2EE compliant Hospital information built with JAVA (TM) technology and Prolog based Inference Engine.

Physician's order is entered through JAVA applet from any PCs in the campus.
Client JAVA Applet communicate with the application server. The application server developed by T-max software inc. (Korea) has been used for this implementation. In the application server, the business logic is coded with the framework CBPF (developed by Japan SUN JCTC).

The physician's order are interpreted and send to the prolog based inference engine (DSP) wrapped by JAVA. The DSP examines the order and returns the result of validation. In accordance with the result of validation, appropriate alert and reminder will be shown to the physician if applicable.

If the order successfully validated or instructed to go forward by the physician, the order is sent to departmental system respectively. The order and the reports of examinations are registered into the patient information central data repository and used to validate the orders that will be entered in future.

Future

1. Consumer self diagnosis and medication
2. Hospital administration
