PER CURIAM:
Dr. A.P. Soriano sued the Nesho-ba County General Hospital’s board of trustees and numerous staff members after his hospital privileges were revoked. He alleged claims for inter alia violation of procedural and substantive due process, defamation, and tortious interference with business relations. The district court granted summary judgment to the defendants, and Dr. Soriano appeals. Reviewing the record de novo, see Carnaby v. City of Houston, 636 F.3d 183, 187 (5th Cir.2011), we AFFIRM for the following reasons:
1. The defendants afforded Dr. Soriano adequate procedural due process by granting him a multi-step peer review and appeal process pursuant to the hospital’s medical staff by-laws. This process included review by the Investigative Committee, the Medical Executive Committee, the Appeals Committee, and the Board of Trustees. Dr. Soriano had the assistance of counsel at a formal hearing, and he was able to testify and cross-examine witnesses before his privileges were revoked. His procedural due process rights were not violated. See, e.g., Finch v. Fort Bend Indep. Sch. Dist., 333 F.3d 555, 562 (5th Cir.2003) (“The essential requirements of procedural due process under the Constitution are notice and an opportunity to respond.”); see also Caine v. Hardy, 943 F.2d 1406, 1411-12 (5th Cir.1991) (en banc).
2. Dr. Soriano asserts that the review process was tainted because Dr. Mann, an Investigative Committee member, was biased, and because the members of the Appeals Committee were not neutral insofar as they stood to benefit financially from his removal from the hospital staff. His assertions are eonclusory and insufficient to create a fact issue in opposition to summary judgment. See Little v. Liquid Air Corp., 37 F.3d 1069, 1075 (5th Cir.1994) (en banc). Moreover, with respect to Dr. Mann, the record shows that members of both the Medical Executive Committee and the Appeals Committee testified that they reviewed the record independently of Dr. Mann’s report. The defendants’ decision to revoke Dr. Soriano’s privileges was neither arbitrary nor capricious. See Lewis v. Univ. of Tex. Med. Branch at Galveston, 665 F.3d 625, 630-31 (5th Cir.2011).
3. Dr. Soriano has failed to create an issue of fact as to whether the nurses were concerned about his failure to transfer a cardiac patient immediately, and whether the nurses ignored his orders to consult with Dr. Yedlapalli during the night. Regardless whether the nurses indicated their concern on the patient’s chart, the record shows that Dr. Soriano knew about the patient’s elevated enzyme levels and that it was not the nurses’ job to tell him how to respond. As for the alleged orders to consult Dr. Yedlapalli, Dr. Soriano did not raise this issue in the district court, and he may not do so for the first time on appeal. See, e.g., Greenberg v. Crossroads Sys., Inc., 364 F.3d 657, 669 (5th Cir.2004) (arguments not raised in opposition to summary judgment may not be raised for the first time on appeal). Furthermore, the patient’s chart, the nurses’ testimony, and even Dr. Sori-ano’s pleadings in the district court, all show that Dr. Soriano ordered the nurses to consult with Dr. Yedlapalli and a cardiologist in the morning.
4.Dr. Soriano’s claim for defamation because the defendants reported the revocation of his privileges to the National Practitioners Data Bank is without merit. The defendants are immune from this state-law claim pursuant to the Health Care Quality Improvement Act (“HCQIA”). See 42 U.S.C. § 11111(a)(1). Dr. Soriano asserts that the defendants were not motivated by a concern for quality health care, see § 11112(a)(1), because they treated him differently than other doctors who allegedly provided deficient care to patients but were not investigated. Besides failing to brief this contention adequately, Dr. Soriano expressly testified that he did not know whether the other doctors were investigated. Although he contends that an investigation of his case was not warranted, we do not second guess the merits of the decision but rather evaluate only whether the defendants afforded Dr. Soriano fair procedures and made a reasonable investigation and a reasonable decision based on the facts before them. See Bryan v. James E. Holmes Reg’l Med. Ctr., 33 F.3d 1318, 1337 (11th Cir.1994); see also Johnson v. Spohn, 334 Fed.Appx. 673, 679-80 (5th Cir.2009). Based on the record, we are satisfied that is the case.
5. Finally, with respect to the claim for tortious interference with business relations, Dr. Soriano provides only speculative and conclusory assertions in his brief. Moreover, the claim, like the state-law defamation claim, is barred under the HCQIA. See § 11111(a)(1).
AFFIRMED.
Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir R. 47.5.4.
