RESUMEN
The World Organization of Family Doctors (WONCA) developed the third edition of the International Classification of Primary Care (ICPC-3) to support the shift from a medical perspective to a person-centered perspective in primary health care. The previous editions (ICPC-1 and ICPC-2) allowed description of 3 important elements of health care encounters: the reason for the encounter, the diagnosis and/or health problem, and the process of care. The ICPC-3 adds function-related information as a fourth element, thereby capturing most parts of the encounter in a single practical and concise classification. ICPC-3 thus has the potential to give more insight on patients' activities and functioning, supporting physicians in shifting from a strict medical/disease-based approach to care to a more person-centered approach. The ICPC-3 is also expanded with a new chapter for visits pertaining to immunizations and for coding of special screening examinations and public health promotion; in addition, it contains classes for programs related to reported conditions (eg, a cardiovascular program, a heart failure program) and can accommodate relevant national or regional classes. Classes are selected based on what is truly and frequently occurring in daily practice. Each class has its own codes. Less frequently used concepts pertaining to morbidity are captured as inclusions within the main classes. Implementation of the ICPC-3 in an electronic health record allows provision of meaningful feedback to primary care, and supports the exchange of information within teams and between primary and secondary care. It also gives policy makers and funders insight into what is happening in primary care and thus has the potential to improve provision of care.
