Book excerpt: This fully revised and corrected edition of the International Classification of Primary Care 2e (ICPC-2) is indispensable for anyone wishing to use the international classification system for classificaton of morbidity data in a primary care setting. The concept of ICPC-2 has not been changed but the main body of the actual classification (chapter 10) has been completely revised to reflect the adequate use for an individual patient record and for research purposes. This now brings the printed version of ICPC-2 completely in-line with the electronic version previously only available through the Oxford Website for the journal Family Practice. ICPC-2 is patient-oriented rather than disease or provider-oriented. It encompasses both the patient's reason for encounter and the patient's problem. ICPC-2 is extensively used internationally and includes a detailed conversion system for linking the ICPC and ICD-10 codes published by WHO, additional inclusion criteria, and cross-referencing rubrics. ICPC-2 It has been developed based on the recognition that building the appropriate primary care systems to allow the assessment and implementation of health care priorities is possible only if the right information is available to health care planners.
