What is the test for qualified immunity for prison officials who deliberately ignore the serious medical needs of an inmate?

A finding of deliberate indifference necessarily precludes a finding of qualified immunity; prison officials who deliberately ignore the serious medical needs of inmates cannot claim that it was not apparent to a reasonable person that such actions violated the law. Albers v. Whitley, 743 F.2d 1372, 1376 (9th Cir.1984), rev'd on other grounds, 475 U.S. 312, 106 S.Ct. 1078, 89 L.Ed.2d 251 (1986). In order to determine whether summary judgment was properly denied, we need only determine whether the plaintiff established a genuine issue of material fact as to whether the defendant prison officials were deliberately indifferent to his medical needs.
