Since independence Tuvalu has had one hospital, the Princess Margaret Hospital (PMH), in Funafuti that provides referral and general health services to support the health clinics on each of Tuvalu's outer islands and for Tuvaluans living on
Funafuti. Each Community Health Centre on the smaller outer islands is staffed by a midwife and general nurse. Since 2008 the health infrastructure on the outer islands was improved with Community Health Centres, with facilities for inpatient care, being built at Vaitupu,
Niutao and
Nui with funding provided by the Japanese government's Grassroots program. In 2010 there were a total of 18 patients sent for surgery, mainly to Fiji. Specialist eye and plastic surgeon teams from
Australia and
Taiwan also visit PMH. The hospital provides outpatient services with outpatient numbers attending PMH falling dramatically from 58,847 in 1990 to 30,395 in 2000; and during this period the inpatient numbers at PMH dropped marginally from 898 to 820. Tuvalu's population to nurse ratio is low by regional standards at about 225:1 (at 2002). ==Health research and vaccination programs==
