Coding rules for the patient summary: analysis and requirements to develop an automated coding system.

In the frame of federated and interoperable Electronic Health Records, specific coding systems are mandatory for filling out the Patient Summary. Because of the sensitivity of its content, PS needs to be validated by General Practitioners. This work proposes a support system based on standardized and formalized coding rules to ease the coding process supporting GPs in the compilation of the PS, thus avoiding coding errors and misspecifications of clinical data.
