Emergency services need to provide care even if annual quotas for specific services are already filled, for example, so the number of such cases can provide some indication of whether quotas are appropriately set. The origin and ultimate destination of patients can also provide an indication of whether capacity in various levels of care is adequate, both in terms of access and quality of care. In 2013, there were 3.1 practicing doctors per 1 000 population, close to the OECD average of 3.2, and a slight increase from 2000 when there were 2.9 practicing doctors per 1 000 population in Latvia.
