It includes health services consumed at the family home and in other individual or collective residences where the individual is located on a permanent basis (e.g. prisons, convents, boarding schools). Health care received by persons residing in a health care facility (e.g. a residential long-term care facility) is to be considered as inpatient care. Greater detail within a class does not necessarily imply more detailed reporting, but rather greater clarity about the content of the aggregates. As with other classifications, the greater the detail presented, the less uncertainty there is while classifying, and the more comparable the results. Additional benefits can be found when breakdowns of the HC classes are compatible with those in other available classifications. The division into general and specialised health services for inpatient and outpatient care should be compatible as far as possible with the COFOG (UN, 1999).
