Appeal from the United States District Court
for the District of Arizona
John Charles Hinderaker, District Judge, Presiding
Submitted November 21, 2025**
Phoenix, Arizona
Before: MURGUIA, Chief Judge, and HAWKINS and HURWITZ, Circuit Judges.
Christopher Brightly brings a 42 U.S.C. § 1983 action against prison
healthcare providers and several of their employees alleging inadequate medical
treatment while he was incarcerated in Arizona state prisons. He appeals a summary
judgment order entered under Federal Rule of Civil Procedure 54(b) on his claims
against Centurion of Arizona, LLC, and Laura Elliott, a Centurion nurse practitioner
(collectively, “Defendants”).
We have jurisdiction under 28 U.S.C. § 1291. “We review de novo the grant
of summary judgment, and review pursuant to Federal Rule of Civil Procedure 56(c),
under which the contested evidence is viewed in the light most favorable to the
nonmoving party . . . .” Johnson v. Barr, 79 F.4th 996, 999 (9th Cir. 2023) (cleaned

up).
We affirm.
1. To prevail on his deliberate indifference claims, Brightly must show “harm
caused by the indifference.” Jett v. Penner, 439 F.3d 1091, 1096 (9th Cir. 2006).
Brightly argues that the district court erred in concluding that expert testimony was
required to show a question of fact as to causation. He contends that because “the
average person” knows that medication tends “to make patients better,” a jury could
conclude, without the benefit of expert testimony, “that if Elliott and Centurion
chose not to follow specialists’ recommendations and failed to provide consistent
medication as prescribed, it could have caused [his] condition to worsen.”
On this record, we disagree. As the district court noted, even assuming that
Defendants failed to follow specialists’ recommendations and inconsistently
dispensed prescribed medication, it does not necessarily follow that Brightly’s
claimed complications were caused by these actions or omissions. The Defendants
submitted expert testimony that Brightly’s complications were not caused by a lapse
of his antifungal medication and that it was “not even clear that” they were caused
by a Valley Fever relapse. Instead, the expert opined that Brightly’s hospitalizations
could have been caused by “worsening stenosis, scarring, vascular impairment,
infection of hardware (non-fungal) or a combination of the above.” Indeed, one of
Brightly’s treating physicians opined that the complications likely resulted from
3 24-7472
delay in diagnosing the disease, which occurred before Defendants undertook
Brightly’s care. The district court therefore did not err in applying the general rule
that expert testimony is needed to show causation in complex medical cases. See
Hutchinson v. United States, 838 F.2d 390, 393-94 (9th Cir. 1988); United States v.
Urena, 659 F.3d 903, 908 (9th Cir. 2011).
2. In the alternative, Brightly argues that the testimony of two treating
physicians, Drs. Sewell and Avila, raises a triable question of fact on causation.
Brightly does not contest the district court’s finding that Dr. Sewell, a family
medicine practitioner, was not a Valley Fever expert. Instead, he contends that
because the district court relied on Dr. Sewell’s opinion in issuing a preliminary
injunction, it must also do so at the summary judgment stage. But the district court
never found Dr. Sewell to be a qualified expert on causation. Moreover, the court
was not required to rely on evidence at summary judgment simply because it did so
when issuing a preliminary injunction. See Herb Reed Enters. LLC v. Fla. Ent.
Mgmt., Inc., 736 F.3d 1239, 1250 n.5 (9th Cir. 2013) (“Due to the urgency of
obtaining a preliminary injunction at a point when there has been limited factual
development, the rules of evidence do not apply strictly to preliminary injunction
proceedings.”).
Brightly also argues that Dr. Avila could provide the required testimony
because a treating physician may testify as to causation “to the extent that his
4 24-7472
opinions were formed during the course of treatment.” Goodman v. Staples The Off.
Superstore, LLC, 644 F.3d 817, 826 (9th Cir. 2011). But even assuming Dr. Avila’s
opinions were formed during treatment, she did not opine that the Defendants’
actions and omissions caused Brightly’s complications. Rather, she concluded:
While it is concerning that Mr. Brightly’s treatment course was
interrupted during the above-mentioned time, it is my professional
opinion that the severity of the patient’s case is more likely due to a
delay in his diagnosis of Coccidiomycosis meningitis. If the patient had
been brought to medical attention for more prompt diagnosis and
initiation of treatment, he likely would not have experienced such a
devastating and complex infection.
The delay in diagnosis occurred before Centurion and Elliott assumed
Brightly’s care.
AFFIRMED.
