Can a prison official demonstrate deliberate indifference to the need for medical treatment?

A prison official shows deliberate indifference to such a need if he "knows of and disregards an excessive risk to inmate health." Peralta, 744 F.3d at 1082 (citing Farmer v. Brennan, 511 U.S. 825, 837 (1994)). This "requires more than ordinary lack of due care." Colwell, 763 F.3d at 1066 (citing Farmer, 511 U.S. at 835). The prison official must "be aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference." Colwell, 763 F.3d at 1066. Prison officials may demonstrate deliberate indifference when they "deny, delay, or intentionally interfere with medical treatment," and prison doctors can be deliberately indifferent in their provision of care.
