b. [STANDARD-OF-CARE OBLIGATION 2 — e.g., "to review pre-operative MRI imaging and verify the surgical level using intra-operative fluoroscopy"];

6.1 To a reasonable degree of medical probability, Defendant [PHYSICIAN] deviated from the applicable standard of care in one or more of the following respects:

a. [SPECIFIC DEVIATION 1, tied to a specific record entry/date] — e.g., "On [DATE], Defendant Physician proceeded with surgery at the L4–L5 level without intra-operative fluoroscopic verification, contrary to the standard of care identified in paragraph 5.1(b)";

b. [SPECIFIC DEVIATION 2];

c. [SPECIFIC DEVIATION 3];

d. [SPECIFIC DEVIATION 4];

e. [SPECIFIC DEVIATION 5].

6.2 To a reasonable degree of medical probability, Defendant [HOSPITAL] (and its nursing, technical, and ancillary staff) deviated from the applicable institutional and nursing standard of care in one or more of the following respects:

a. [SPECIFIC DEVIATION 1];

b. [SPECIFIC DEVIATION 2];

c. [SPECIFIC DEVIATION 3].

6.3 The deviations identified in paragraphs 6.1 and 6.2 are not subject to legitimate medical-judgment dispute and represent breaches of duty rather than disagreements among reasonable practitioners.

7. OPINIONS REGARDING CAUSATION

7.1 To a reasonable degree of medical probability, the deviations from the standard of care identified in paragraphs 6.1 and 6.2 were a direct and proximate cause of Plaintiff's injuries, including:

a. [INJURY 1 — e.g., "transection of the L5 nerve root resulting in left-foot drop, sensory deficit in the L5 dermatome, and chronic neuropathic pain"];

b. [INJURY 2];

c. [INJURY 3].

7.2 But for Defendants' deviations from the standard of care, Plaintiff would not, more likely than not, have suffered the injuries identified in paragraph 7.1.

7.3 The injuries identified in paragraph 7.1 were a foreseeable consequence of the deviations identified in paragraphs 6.1 and 6.2.

8. OPINIONS REGARDING DAMAGES (CLINICAL ASPECTS)

8.1 The clinical sequelae of the injuries identified in paragraph 7.1 include, to a reasonable degree of medical probability, the following past and future consequences:

b. [ONGOING TREATMENT NEEDS — e.g., "physical therapy 2x/week for [duration], chronic-pain management with [modalities], and possible future revision spinal surgery within the next 5–10 years"];

13. OKLAHOMA PRACTICE NOTES

13.1 Constitutional Posture

13.1.1 No statute requires this Affidavit. Zeier v. Zimmer (2006) struck down the original § 19; the legislature re-enacted essentially identical language in 2009; Wall v. Marouk (2013) struck the re-enacted version; the legislature re-enacted again as § 19.1 in 2013; John v. Saint Francis (2017) struck the third version. The Oklahoma Supreme Court's reasoning is consistent: the statute creates a sub-class of "professional tort victims" who must shoulder costs (estimated $500–$5,000 per affidavit) not borne by other tort plaintiffs, in violation of Okla. Const. art. 5, § 46 (special-laws prohibition) and Okla. Const. art. 2, § 6 (open-courts/access-to-courts guarantee).

13.1.2 Practical effect. A defendant's motion to dismiss for "failure to file an affidavit of merit" is a non-starter in Oklahoma state court; cite John v. Saint Francis directly. Some defendants raise § 19.1 in unfamiliarity or to test the plaintiff; expect and rebut.

13.2 Federal Court (Erie) Considerations

13.2.1 In a diversity case removed to or filed in the U.S. District Courts for the Northern, Eastern, or Western Districts of Oklahoma, AOM statutes from other states are generally treated as procedural in the Tenth Circuit (and therefore not applied) — but the issue is unsettled across circuits. Because Oklahoma's own AOM statute is unconstitutional, Erie analysis is largely academic for OK-law claims; verify before relying.

13.3 When to Use This Voluntary Affidavit

13.3.1 Use when:

a. The case is high-stakes and counsel desires written documentation of expert review for the work-product file;

b. Pre-suit demand to a hospital risk-management or medical-malpractice carrier benefits from a sworn expert statement;

c. Defense files a 12 O.S. § 2011 motion or In re Friot sanctions motion challenging the good-faith basis for the petition;

d. The plaintiff seeks summary disposition on a discrete issue early in the case and wants record support.

13.3.2 Avoid when:

a. The expert's identity should remain non-testifying/consulting (filing waives § 3226(B)(4)(b) protection);

b. The opinions are not yet sufficiently developed to withstand cross-examination;

c. The defense will use the affidavit to lock the expert into early opinions before the medical record is complete.

13.4 Expert Admissibility

13.4.1 At trial, the expert must satisfy 12 O.S. § 2702 (Oklahoma's Daubert-style standard adopted in Christian v. Gray, 2003 OK 10, 65 P.3d 591). Confirm the expert's methodology meets reliability and relevance criteria before using the affidavit.

13.5 Rule 11 / § 2011 Anchor

13.5.1 12 O.S. § 2011(B)(3) requires that factual contentions in any signed pleading have evidentiary support or be likely to have evidentiary support after a reasonable opportunity for further investigation. A documented expert review supports the good-faith basis for medical-negligence allegations, even though no statute compels it.

13.6 Privilege Map

13.6.1 Consulting expert (not testifying) — opinions and identity protected under 12 O.S. § 3226(B)(4)(b) absent exceptional circumstances.

13.6.2 Testifying expert — opinions discoverable under § 3226(B)(4)(a); draft reports and attorney-expert communications retain limited work-product protection consistent with the 2010 federal Rule 26 amendments and Oklahoma case law.

13.6.3 Filed affidavit — public record; privilege waived as to subject matter disclosed.
