The International Classification of Primary Care (ICPC): new applications in research and computer-based patient records in family practice.

The international Classification of Primary Care (ICPC) has now been available to the family medicine community for a decade as the main ordering principle of its domain. Research data and practical experiences with ICPC, as well as the development of new concepts in family medicine, have resulted in new applications. The structure of episodes of care to be included in a computer-based patient record has been further developed and refined. ICPC as the ordering principle of patient data is now available in 19 languages. Its conversion structure with the International Classification of Diseases (ICD-10) allows the highest possible level of specificity in a patient's problem list necessary in patient care, while the compatibility of the ICPC drug codes with the Anatomic Therapeutic Chemical Classification Index allows the systematic inclusion of data on prescription.
