Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS WESTERN DIVISION

Gary Hancock,

Plaintiff, Case No. 3:22-cv-50103 v. Honorable Iain D. Johnston United States, et al.,

Defendants.

MEMORANDUM OPINION AND ORDER

Plaintiff Gary Hancock, a federal prisoner, brings this action against the United States and individual medical providers (Defendants) under the Federal Tort Claims Act (FTCA) and Bivens alleging negligence, malpractice, and deliberate indifference to serious medical needs during his incarceration at then USP Thomson. Hancock alleges that Defendants knew he suffered from extreme abdominal pain but failed to take appropriate steps to address it. He also alleges that Defendants failed to provide him with his medication while he was held in Thomson’s Special Housing Unit. Hancock’s retained opinion witness is Dr. Susan E. Lawrence. She is board certified in internal medicine and is a former medical director of a federal detention facility with over forty years of experience in the medical field. After reviewing medical records, depositions, and other materials, Dr. Lawrence reached several different conclusions about the medical care Defendants provided Hancock. Defendants seek to bar Dr. Lawrence’s opinions under Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993). They also seek to bar the testimony of certain other fact witnesses. For the reasons that follow the Court grants the motion

in part and denies the motion in part. I. Discussion A. Legal Standards for Daubert Motion According to Federal Rule of Evidence 702: [A] witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if the proponent demonstrates to the court that it is more likely than not that: (a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert’s opinion reflects a reliable application of the principles and methods to the facts of the case. The district court is tasked with ensuring that only relevant and reliable opinion testimony is presented to a jury. Daubert, 509 U.S. at 597; Lees v. Carthage Coll., 714 F.3d 516, 521 (7th Cir. 2013). The proponent carries the burden of establishing the admissibility of evidence by the preponderance of the evidence. Gopalratnam v. Hewlett-Packard Co., 877 F.3d 771, 782 (7th Cir. 2017). A district court has significant discretion in performing the required Daubert analysis, but it must perform the analysis in some depth. Id. at 784. It must carefully consider “(1) the proffered expert’s qualifications; (2) the reliability of the expert’s methodology; and (3) the relevance of the expert’s testimony.” Id. at 779. B. Dr. Lawrence’s Opinions Defendants object to the admissibility of Dr. Lawrence’s top-line conclusions and several secondary statements on the grounds that she is not qualified to be an

expert, that she offers improper legal conclusions, that she fails to appropriately opine as to the standard of care, and that her disclosures fall short of the requirements of the Federal Rules of Civil Procedure. a. Dr. Lawrence is Qualified to Offer the Opinions An expert witness may only offer testimony if they are qualified by “knowledge, skill, experience, training, or education . . . .” Fed. R. Evid. 702. The

issue isn’t whether an expert is qualified generally, but whether they have the qualifications to reach each proffered conclusion. United States v. Truitt, 938 F.3d 885, 890 (7th Cir. 2019). “[O]rdinarily, courts impose no requirement that an expert be a specialist in a given field.” Gayton v. McCoy, 593 F.3d 610, 617 (7th Cir. 2010) (citation omitted). “The fact that an expert may not be a specialist in the field that concerns her opinion typically goes to the weight to be placed on that opinion, not its admissibility.” Hall v. Flannery, 840 F.3d 922, 929 (7th Cir. 2016).

Dr. Lawrence received her medical degree in 1978. Dkt 116-1 at 2. She has been board certified in internal medicine since 1983 and in medicinal oncology since 1985. Id. She was in private practice as a medical oncologist from 1985 to 1992. Id. From 1992 to 2011 she focused on providing cancer treatment to the HIV/AIDS population. Id. She also served, from 2013 to 2016, as a staff physician and medical director at the Adelanto Detention Facility, a federal detention facility. Id. In that role she supervised nurses and provided primary and supervisory care for detainees with medical problems that included gastrointestinal disorders. Id. at 2-3. Defendants point out, accurately, that Dr. Lawrence isn’t a

gastroenterologist. This means, they contend, that “she should be barred from testifying as to any gastroenterology diagnosis, what testing is appropriate to determine if Hancock has celiac disease or non-celiac gluten sensitivity, the standards for diagnosing these conditions, and the proper treatment for these conditions. . . .” Dkt. 165 at 5. Defendants also argue that Dr. Lawrence can’t testify as to whether any particular tests are the “gold standard” for diagnosing celiac

disease. Id. at 7. Although the record is relatively sparse on the issue, Dr. Lawrence has experience treating and managing GI disorders in both the prison setting and outside of it. Dkt. 116-1 at 2. Her testimony on the level of expertise that is required is decidedly mixed. On the one hand, she testified that “celiac disease is a condition that internists also treat… celiac disease is something that’s in the purview of internal medicine as well.” Dkt. 165-1 104:2-6. On the other hand, she also testified

that celiac diagnosis and treatment would be for a gastroenterologist. Id. at 104:15. Given the subject of Dr. Lawrence’s opinions and her background and experience, she is qualified to opine about the diagnosis, testing, and treatment of celiac disease and non-celiacs gluten sensitivity. Dr. Lawrence isn’t making a diagnosis. Knowledge about how celiac disease and non-celiac gluten sensitivity are tested, diagnosed, and treated isn’t “specialized knowledge held only by [gastroenterologists].” Gayton, 593 F.3d at 618. It’s general medical information well within Dr. Lawrence’s wheelhouse as an internal medicine practitioner. Defendants also object to Dr. Lawrence’s critique of Dr. Olney. Specifically,

Defendants argue that Dr. Lawrence only bases her opinion of Dr. Olney— specifically that Olney’s order of a gluten-free diet for Hancock delayed Hancock’s treatment—on Dr. Shadid’s deposition testimony. An expert can’t merely relay the opinion of another expert when that expert has a different specialty. Dura Auto. Sys. of Ind., Inc. v. CTS Corp., 285 F.3d 609, 614 (7th Cir. 2002); Sommerfield v. City of Chicago, 254 F.R.D. 317, 324 (N.D. Ill.
