In 1980, it was 6847, in 1990, it was 6768, and in 2002, it was 6222. By age group, the rate of estimated patients for 65 and older patients had increased until 1990, but has declined since then. The rates for other age groups had remained almost unchanged and are now declining. The rate of outpatients for the age group of 65 and older drastically increased from 1965 to 1975. Though it declined in 1980, it had increased until 1996, and has been declining since 1999. The rates for other age groups are declining gradually.
