WASHINGTON (AP) - American Indians often do not have adequate access to health care, congressional investigators said Friday.

The Government Accountability Office said many government-funded Indian Health Service facilities do not provide adequate behavioral health or specialty dental care. The agency also falls short in providing care for non-urgent conditions such as arthritis, allergies and chronic pain, investigators said.

"Most of the facilities we visited lacked the equipment necessary for certain ancillary services and had few medical specialists on site," GAO said.

The report said many American Indians and Native Alaskans do not have means of transportation and are not able to travel long distances to IHS facilities.

Long wait times between the scheduling of an appointment and delivery of service are also a problem, investigators said.
