Hawai'i boasts the fourth-highest rate for private nursing rooms, according to a new study that found the average daily cost is 44 percent higher here than the national average.

The average daily rate in Hawai'i was $306 a day in 2008, a study by the MetLife Mature Market Institute found. That works out to $111,690 a year.

Hawai'i trailed only Alaska, Connecticut and New York in statewide daily rates and was $94 higher than the national average of $212. The costs here are tied in part to the higher cost of doing business in the state, which includes higher wages, energy costs, services and materials.
