NATIVE AMERICAN HEALTH CARE is facing challenges that are unprecedente
d in its history. External forces are intensifying those challenges; t
hree are particularly powerful. (a) the gradual but accelerating assum
ption of responsibility for delivery of clinical services by tribal go
vernments and the concomitant decrease in direct U.S. Indian Health Se
rvice (IHS) operational responsibility; (b) resource constraints resul
ting from Federal appropriations insufficient to cover inflationary co
sts and thus not capable of sustaining levels of services, particularl
y during the 1990s;(1) and (c) the growth of managed cave and increasi
ng interest by managed care organizations in contracting with tribes f
or delivery of clinical services.
