PRESIDING JUSTICE HOWSE delivered the judgment of the court.

ORDER

¶ 1 Held: The judgment of the circuit court of Cook County is affirmed in part and reversed 

in part. The trial court erred when it barred plaintiff’s expert from testifying about the 

delay in the patient’s treatment and whether such delay was a proximate cause of the 

decedent’s death. The resulting directed verdict in favor of the nurse defendants on the 

basis that there was no evidence to create a question of fact on the issue of proximate 

cause is reversed. The jury verdict in favor of the defendant doctor stands.

¶ 2 Plaintiff brought this wrongful death medical malpractice action against the deceased 

patient’s treating physician and nurses following the patient’s death from septic shock. At the 

jury trial, the trial court barred plaintiff’s controlled expert witness physician from testifying that 

the defendant nurses deviated from the standard of care and proximately caused the patient’s 

death. The court barred the testimony on the basis that those opinions had not been disclosed 
1-19-1420 

- 2 - 

prior to trial in accordance with Illinois Supreme Court Rule 213. Having barred plaintiff’s sole 

causation expert relative to defendant nurses, the trial court entered a directed verdict in the 

nurses’ favor. The claims against the doctor went to the jury. The jury rendered a verdict of no 

liability for the defendant physician. 

¶ 3 Plaintiff appeals arguing that the trial court erred in (1) barring plaintiff’s controlled 

expert physician’s causation opinions relative to defendant nurses; (2) barring plaintiff’s 

controlled expert physician from testifying that defendant nurses deviated from the standard of 

care; and (3) granting a directed verdict in favor of defendant nurses. Defendant also requests 

that, in the event a new trial is granted with respect to defendant nurses, the jury verdict for 

defendant doctor should be reversed so that the doctor can be included as a defendant in the new 

trial.

¶ 4 For the following reasons, the judgment of the circuit court of Cook County is affirmed in 

part and reversed in part and the case is remanded for further proceedings. 

¶ 5 BACKGROUND

¶ 6 Plaintiff, Tierra Meeks, special administrator of the Estate of decedent patient, Elaine 

Jones, filed this wrongful death medical malpractice action against Elisabeth Schreiber and Mark 

Jasper (collectively “defendant nurses”) and Dr. Vinodinee Dissanayake (Dr. Dissanayake) 

related to care provided to Jones in the emergency department at the University of Illinois 

Chicago Hospital (UIC) prior to her death. 

¶ 7 Elaine Jones’ Treatment at UIC

¶ 8 A general timeline of Jones’ treatment at UIC follows. Between 5 p.m. and 6 p.m. on 

November 22, 2013, Jones was working as an employee registrar at UIC when she walked over 

to the triage desk and reported to the triage nurse, defendant Schreiber, that she had not been 
1-19-1420 

- 3 - 

feeling well. Jones was alert, oriented, and talking normally. Schreiber performed a nursing 

triage assessment of Jones in Triage Room 1. 

¶ 9 Jones’ Triage Assessment

¶ 10 The triage process involves a “brief nursing assessment” including the patient’s chief 

complaint, vital signs, medical history, and medications and interventions pertaining to the 

patient’s chief complaint or which are necessary to determine the right triage category. The 

triage category is a number 1 through 5 on the Emergency Severity Index (ESI) that is assigned 

to a patient with 1 being the most serious—the patient has life-threatening issues requiring 

immediate attention—and 5 being the least serious—the patient has a minor issue or ailment and 

would typically be seen in the “fast track area.” The “fast track area” is an area within the 

emergency department staffed by an advanced practice nurse.

¶ 11 Schreiber, after completing her assessment, noted Jones had an elevated respiratory rate 

of 22 where 20 is considered normal range, normal blood pressure, a normal heart rate, and a 

low-grade fever of 100.6 degrees Fahrenheit. Schreiber accessed Jones’ electronic medical 

record at UIC which showed Jones’ most recent visit to the emergency room and that she 

suffered from diabetes and idiopathic thrombocytopenia purpura (ITP)—a condition which 

affects the blood’s ability to clot. 

¶ 12 Schreiber learned from Jones that she was taking Metformin for her diabetes. Schreiber 

did not ask if Jones had any prior surgery—which she did, a splenectomy. Schreiber did not ask 

Jones if she was taking steroids—which she was. Schreiber gave Jones Tylenol and juice 

because Jones’ blood sugar was on the lower side of normal. 

¶ 13 Based on her triage assessment, Schreiber categorized Jones as an ESI 3. This meant 

Jones needed attention in the emergency department and would require two or more resources 
1-19-1420 

- 4 - 

which could include intravenous administration of fluids or medicine, blood testing, and 

electrocardiogram (EKG) and/or radiology studies. 

¶ 14 Systematic Inflammatory Response (SIRS) is a broad syndrome identified by a group of 

four measurements including elevated heart rate, respiratory rate, temperature, and white blood 

count. These measurements, referred to as the SIRS criteria, allow healthcare providers to 

identify if a patient is at risk of developing a worsening infection. Three out of the four 

measurements were ascertainable at triage. Jones had two of the three SIRS criteria at triage. 

Jones’ measurements on the SIRS criteria would raise suspicion of sepsis.

¶ 15 At 5:28 p.m. an EKG was performed on Jones which did not show an acute coronary 

event.

¶ 16 After Schreiber’s initial triage, Jones was seen in Triage 2, where a second EKG was 

taken, blood was drawn, and labs were taken, after which Jones was returned to the triage 

waiting area. At 6:50 p.m., Schreiber saw Jones in the waiting room and took another set of 

vitals. Jones’ respirations were within the normal range and she was alert and oriented. 

Thereafter Jones was moved out of triage, and Schreiber provided no further care to Jones.

¶ 17 Jones’ Care in the Emergency Department 

¶ 18 Upon leaving triage, Jones was transferred to a bed in the back hallway of the emergency 

department, which is done when there are no other available beds. 

¶ 19 At around 7:00 p.m., Dr. Dissanayake was handed Jones’ second EKG for assessment. 

The EKG showed Jones’ heart rate was 108 beats per minute. Dr. Dissanayake went to see Jones 

and did a cursory physical exam. Jones was talkative and appeared stable to Dr. Dissanayake. 

Jones said that she was experiencing chest pressure. Jones had been having malaise, fever, and 

chills. Dr. Dissanayake asked Jones for additional history including her medical and surgical
1-19-1420 

- 5 - 

history. Jones responded that she had ITP and diabetes. Dr. Dissanayake asked Jones for her 

medications and Jones told her she was taking Metformin. Around 7:11 p.m., Dr. Dissanayake 

reviewed Jones’ vitals, labs, and any notes made related to Jones. Dr. Dissanayake 

acknowledged that, had she known Jones did not have a spleen, she would have been more 

acutely aware of the need to really evaluate the fever and chest pain. But Dr. Dissanayake stated 

that it would not have changed what she did. 

¶ 20 Defendant Jasper, a nurse practitioner, was working in the fast-track section of UIC’s 

emergency department the night of Jones’ visit. The fast-track area is reserved for lower acuity 

patients with an ESI 4 or 5. Jasper first encountered Jones while she was in the hallway bed at 

approximately 8:24 p.m., having recognized her as a co-worker. Jasper was not assigned to 

Jones nor was he involved in orders placed under his name prior to that time, including the IV 

capped catheter placed on Jones’ arm, blood work, and a urinalysis. Upon seeing Jasper, Jones 

told him she felt cold. Jasper performed a quick physical of Jones in the hallway and listened to 

her heart and lungs. Jasper noted Jones was tachycardic—meaning Jones had an elevated heart 

rate—when he listened to her lungs. Jones’ heart rate was only up a little bit. Jasper pushed on 

her stomach but did not lift her shirt or take her pants off because she was in the hallway in plain 

view of others. Jones was alert, orientated, and had no acute distress. 

¶ 21 Jasper brought Jones to a bed in fast-track. He asked Jones about her medical history and 

she told him she recently started taking Metformin. He asked her if she was diabetic. Jasper 

placed Jones on a monitor and saw that her heart rate was elevated and that she had a fever but 

had no other abnormal vitals. While Jasper was attending to other patients, another nurse, Donna 

Entrekin, notified him that Jones was complaining of mid-sternal chest and abdominal pain. 

Around 8:37 p.m. Jasper entered an order for pain and nausea medication, a flu swab, additional 
1-19-1420 

- 6 - 

fluids, and an EKG. Jasper administered the pain medication through an IV with fluids that had 

been started when he brought Jones into fast-track. At 8:45 p.m. the results of an EKG Jasper 

ordered were returned abnormal. 

¶ 22 Between 8:45 p.m. and 8:55 p.m., Jasper was notified by Entrekin that Jones’ mental 

status had changed—she had begun slurring her words and was slow to respond. Jasper had 

intended to perform a full head to-toe examination of Jones but when she became acutely ill, he 

prioritized her care and got Dr. Dissanayake involved just before 9:00 p.m. Jasper shared the 

information he had about Jones’ condition. When Dr. Dissanayake saw Jones, she was moaning 

and not responding to questions. She listened to Jones’ lungs and heart. 

¶ 23 At 8:55 p.m. an order was entered for a computed tomography (CT) scan of Jones’ brain 

which Jasper and Dr. Dissanayake discussed because the doctor was concerned about a bleed, 

meningococcemia, or meningitis. At 8:59 p.m. there was an order for IV fluids. At around 9:00 

p.m., Dr. Dissanayake gave a verbal order for antibiotics and additional fluids to be started which 

she wanted administered right away before the patient went to CT. At 9:03 p.m. a blood culture 

was completed. Between 9:03 p.m. and 9:07 p.m. Jones was taken out of the fast-track area and 

brought to a room, after which Jasper provided no further care for Jones as he remained in fasttrack. 

¶ 24 By 9:50 p.m. Jones had returned from the CT scan. Dr. Dissanayake went to Jones’ room 

at 10:00 p.m. Jones was placed on a monitor. At 10:18 p.m. the antibiotics that Dr. Dissanayake 

ordered were administered. Dr. Dissanayake was frustrated by the delay in administering the 

antibiotics to Jones. Dr. Dissanayake thought Jones looked improved since the last time she saw 

her. 
1-19-1420 

- 7 - 

¶ 25 Shortly thereafter, Jones’ heart rate went from the 90s to the 160s within seconds and her 

blood pressure had dropped. Jones became agitated, stated she could not breathe, and tried to 

pull out her IVs. At 10:40 p.m., Jones was moved to another room where she was intubated. 

Jones lost her pulse. CPR was attempted but unsuccessful. Jones was pronounced dead at 12:50 

a.m. on November 23, 2013.

¶ 26 Trial Testimony 

¶ 27 Plaintiff retained three experts who testified at trial: (1) nurse practitioner Kristen Harris 

who testified to the standard of care applicable to Jasper and his alleged deviations therefrom; (2) 

nurse Scott DeBoer who testified to the standard of care applicable to Schreiber and her alleged 

deviations therefrom; and (3) medical doctor Steven Gabaeff who testified to the standard of care 

applicable to Dr. Dissanayake, her alleged deviations therefrom, and that these deviations by Dr. 

Dissanayake proximately caused Jones’ death. 

¶ 28 R.N. Scott DeBoer’s Expert Witness Testimony

¶ 29 Registered nurse Scott DeBoer testified as plaintiff’s controlled expert. DeBoer was the 

only expert to testify at trial about Schreiber’s alleged deviation from the standard of care. 

DeBoer testified that Schreiber deviated from the standard of care by (1) not obtaining a 

complete medical and surgical history from Jones; and (2) based on that failure, did not assign 

Jones a level 2 ESI categorization at triage and instead assigned her a level 3 ESI.

¶ 30 DeBoer explained that obtaining a complete medical and surgical history involved asking 

Jones whether she had any major surgeries in the past because it would be necessary to know if 

Jones had a splenectomy. DeBoer testified that it would also be necessary to ask Jones what 

medications she was taking. DeBoer explained that Jones was taking a high dose of steroids 

which was important to know because steroids make it hard to fight infection. 
1-19-1420 

- 8 - 

¶ 31 DeBoer acknowledged, however, that Schreiber did ask Jones about her medical history, 

but that Jones failed to advise Schreiber that she did not have a spleen and was taking steroids. 

DeBoer further testified that “if a patient with all of the other characteristics of Elaine Jones 

walked into an emergency department without a splenectomy and without a history of steroids, 

that patient would have been appropriately categorized as an ESI-3.” 

¶ 32 Nurse Kristen Harris, R.N.’s Expert Opinion Witness Testimony

¶ 33 At trial, family nurse practitioner Kristen Harris testified as plaintiff’s controlled expert 

witness. Harris was the only expert to testify at trial about Jasper’s alleged deviation from the 

standard of care. Harris testified that Jasper deviated from the standard of care when he (1) 

failed to take an adequate history from Jones, i.e. when he provided medications and provided an 

ineffective report to the attending physician upon transferring Jones from a hallway bed to the 

fast-track department; (2) failed to timely transfer Jones’ care to an attending physician which 

should have occurred when he took Jones back to fast-track; and (3) failed to timely order IV 

fluids and antibiotics, obtain additional laboratory and physical examinations including blood 

pressure, heart rate, respiratory rate, oxygen saturation, and temperature. 

¶ 34 Harris elaborated:

“A thorough history would have revealed the severity of [Jones’] symptoms as 

well as viewing the medical records such as vital signs and laboratory data as well 

as past medical history which was extremely significant in this situation, because 

it placed her at very high risk due to her symptoms since she was a diabetic, she 

had had her spleen removed, she had a condition that was called ITP which 

affected her ability to clot, and she had prior records that were available for a 
1-19-1420 

- 9 - 

provider to view and that was not apparently considered when he assumed care 

and placed orders.” 

Harris indicated it was not clear whether a physical examination was conducted, noting that one 

was documented in Jones’ records but it stated an “assessment of her abdomen did not reveal any 

scars which would have easily been seen if the patient would have not had their clothes on and 

would have had an appropriate gown to facilitate a thorough physical examination.” Harris 

explained: 

“I think that if the attending emergency room physician would have had 

awareness of the complete picture of the vital signs, of the labs that had been 

taken, if an adequate history had been done by the nurse practitioner, then perhaps 

valuable time getting a CT would not have occurred and her sepsis could have 

been treated sooner.” 

Harris acknowledged that antibiotics were ordered at 9:00 p.m. by Dr. Dissanayake within an 

hour of Jasper’s first involvement with Jones.

¶ 35 Barring of Dr. Gabaeff’s Testimony About Jasper and Schreiber

¶ 36 Dr. Gabaeff was called by plaintiff and testified to Dr. Dissanayake’s standard of care 

deviations and his opinion that these deviations proximately caused Jones’ death. Dr. Gabaeff’s 

trial testimony did not include causation opinions relative to the nurse defendants. 

¶ 37 The day after Dr. Gabaeff’s testimony was concluded, plaintiff made an oral motion to 

recall Dr. Gabaeff to the stand to ask whether he had an opinion whether the deviations in the 

standard of care by Schreiber and Jasper, including the failure to get an adequate history, 

proximately caused a delay in treatment or injury to Ms. Jones. Initially, defendants objected 

based on prejudice and the trial court ruled that Dr. Gabaeff would be allowed to testify that 
1-19-1420 

- 10 - 

“Nurse Schreiber and Nurse Jasper *** their failure to get the adequate history and know about 

these issues caused or contributed to the death.” 

¶ 38 However, prior to Dr. Gabaeff taking the stand for the second time, defendants raised a 

second objection arguing that Dr. Gabaeff should be barred from testifying to causation relative 

to Schreiber and Jasper because these opinions had not been properly disclosed pursuant to 

Supreme Court Rule 213. 

¶ 39 Decision to Bar Dr. Gabaeff’s Opinions Relative to Defendant Nurses

¶ 40 The trial court barred Dr. Gabaeff from testifying as to the standard of care relative to 

both Schreiber and Jasper, citing Illinois caselaw which prevents a physician from testifying as 

to a nurse’s standard of care and deviations therefrom. During argument on plaintiff’s motion to 

recall Dr. Gabaeff, plaintiff pointed to Dr. Dissanayake’s trial testimony in which she stated that

it would be important for her to know whether Jones had a spleen or not, but further stated that

this knowledge would not have changed the course of her treatment. The trial court responded 

stating, 

“So [Dr. Dissanayake] doesn’t even provide causation because [] she said if they 

had known about the spleen, of course I would have done something differently 

‘but I didn’t know it, so that’s why I did that.’ She doesn’t give that.” 

¶ 41 Following argument on defendants’ objection to portions of Dr. Gabaeff’s testimony, the 

trial court concluded that Dr. Gabaeff could not provide opinion testimony of causation relative 

to defendant nurses because (1) there was nothing linking what Dr. Gabaeff proposed to testify 

about regarding the nurses’ deviations from the standard of care with the deviations testified 

about by nurses Harris and DeBoer; and (2) Dr. Gabaeff’s opinion as to the nurses’ deviations 

from the standard of care were not previously disclosed. The trial court ruled the causation 
1-19-1420 

- 11 - 

opinions relative to the nurse defendants that plaintiff sought to elicit upon recalling Dr. Gabaeff 

were new opinions, were not logical corollaries of his previously disclosed opinions, and thus 

were impermissible. 

¶ 42 The trial court stated that the basis for its ruling was Dr. Gabaeff’s failure to link his 

opinions to the deviations testified to by plaintiff’s nursing experts. The trial court explained that 

Dr. Gabaeff’s opinions had to be disclosed prior to trial, which it concluded did not occur here 

because the deviations from the standard of care testified about by the nurse experts were not the 

same as the deviations on which Dr. Gabaeff’s opinions as to proximate cause were based. The 

trial court found that Dr. Gabaeff sought to provide his opinion as to the nurses’ conduct being a 

proximate cause in this case based on trial testimony rather than his own previously disclosed 

opinions. Specifically, the trial court found that Dr. Gabaeff’s opinion as to proximate cause for 

the nurses’ actions would include support from the opinions offered by Harris and DeBoer as to 

the nurses’ deviations from the standard of care. The trial court concluded that an opinion by Dr. 

Gabaeff based upon the trial testimony would be a new opinion, presented impermissibly for the 

first time at trial. Based on the trial court’s ruling, Dr. Gabaeff was not recalled to testify and 

plaintiff’s case-in-chief was concluded. 

¶ 43 Directed Verdict and Posttrial Motion

¶ 44 At the close of plaintiff’s case, the trial court granted defendant nurses’ request for a 

directed verdict in their favor on the grounds that plaintiff failed to present proximate cause 

evidence relative to defendant nurses. Thereafter, Dr. Dissanayake put on her case and the jury 

found in her favor. The trial court entered judgment on the jury’s verdict.

¶ 45 Plaintiff filed a posttrial motion requesting a new trial. In her motion, plaintiff pointed to 

various alleged errors by the trial court, including an argument that the trial court erred when it 
1-19-1420 

- 12 - 

barred Dr. Gabaeff from testifying about whether defendant nurses’ negligence was a proximate 

cause of death. Plaintiff did not argue in her posttrial motion that the jury’s verdict against Dr. 

Dissanayake is against the manifest weight of the evidence. However, in her reply to 

defendants’ response to the motion for new trial, plaintiff argued that the jury could not properly 

consider Dr. Dissanayake’s fault once the directed verdict was entered against defendant nurses, 

reasoning that “it was the nurses who failed to properly advise Dr. Dissanayake of Ms. Jones’ 

true condition” so “[t]he jury had to figure that if the nurses did nothing wrong, then the doctor 

couldn’t have done anything wrong either.” 

¶ 46 The trial court denied plaintiff’s posttrial motion, and this appeal followed. 

¶ 47 ANALYSIS

¶ 48 On appeal, plaintiff argues the trial court erred in (1) barring Dr. Gabaeff from testifying 

that defendant nurses deviated from the standard of care; (2) barring Dr. Gabaeff from testifying 

the defendant nurses’ negligence was a proximate cause of decedent’s death; and (3) granting a 

directed verdict in favor of defendant nurses. Plaintiff also argues that, in the event a new trial is 

granted as to defendant nurses, Dr. Dissanayake should also be a defendant in that new trial.

¶ 49 A trial court’s evidentiary rulings, including its decisions on whether to admit expert 

testimony, are reviewed for an abuse of discretion. Davis v. Kraff, 405 Ill. App. 3d 20, 28 

(2010). “Faced with a challenge that testimony was not disclosed or exceeds the scope of Rule 

213 disclosure, a trial court’s ruling on the admission of evidence is an exercise of its discretion 

and will not be reversed absent an abuse of that discretion.” Steele v. Provena Hospitals, 2013

IL App (3d) 110374, ¶ 93, citing Sullivan v. Edward Hospital, 209 Ill. 2d 100, 109 (2004). An 

abuse of discretion occurs when the trial court applies the wrong legal standard or used the 

wrong legal criteria. Shulte v. Flowers, 2013 IL App (4th) 120132, ¶ 23. A trial court’s decision 
1-19-1420 

- 13 - 

to enter a directed verdict is a question of law which we review de novo. Sullivan v. Edward 

Hospital, 209 Ill. 2d 100, 112 (2004). 

¶ 50 On appeal, plaintiff first argues that the trial court abused its discretion when it denied 

plaintiff’s request to recall Dr. Gabaeff to testify that defendant nurses’ negligence was a 

proximate cause of decedent’s death because plaintiff properly disclosed this opinion by Dr. 

Gabaeff in discovery. Plaintiff argues defendants “were on notice of Dr. Gabaeff’s opinion” that 

“all of the defendants’ negligence proximately caused” the death, including the nurse defendants. 

Plaintiff in part argues this opinion was disclosed when defendants questioned Dr. Gabaeff about 

his notes at his deposition where his notes were an exhibit to his deposition. Plaintiff argues that 

after discovery the “thrust of this case was clear *** defendant nurses failed to take a complete 

history and examination and communicate that history to the attending doctor;” and that had they 

done so and not deviated from the standard of care, “an attending physician acting within the 

standard of care, would have given [decedent] fluids and antibiotics and she most likely would 

have recovered.” 

¶ 51 In support of this conclusion, plaintiff relies on the following disclosures made during 

discovery: 

1. Plaintiff’s Rule 213 answers to interrogatories stated “The hospital mistriage, the failure to be seen in a timely manner, the NP [(nurse practitioner)] 

inability to recognize and communicate, effectively with the provider and the 

provider’s ill informed and poor decision making at the critical moments, 

constitutes gross negligence in failing to meet the standard of care in this critical 

life threatening situation.” 
1-19-1420 

- 14 - 

2. Plaintiff’s Rule 213 answers to interrogatories stated the nurse practitioner 

placed decedent in the hall without having examined her and “not fully aware of 

the history which was clear for infection and sepsis, prior to full shock setting in.” 

3. Dr. Gabaeff’s notes stated the triage nurse did not perform a proper 

medical screening.

4. Dr. Gabaeff’s notes stated the emergency department at UIC failed to 

elicit decedent’s history of a splenectomy or her dosage of prednisone therapy.

5. The nurses failed to review decedent’s primary care clinic record.

6. The triage nurse failed to learn of the splenectomy.

¶ 52 Defendants respond that plaintiff failed to properly disclose Dr. Gabaeff’s proposed 

testimony pursuant to Rule 213. Defendants reason that the trial court properly found that “the 

causation opinions that Plaintiff sought to elicit from Dr. Gabaeff were not previously linked to 

the criticisms testified to by Nurses DeBoer and Harris that [defendant nurses] failed to obtain a 

history of splenectomy and steroids.” Defendants assert the information disclosed in plaintiff’s 

Rule 213 answers to interrogatories and Dr. Gabaeff’s report speak only to negligence and not 

proximate cause; and Dr. Gabaeff’s notes “were neither part of his Rule 213 disclosure nor 

discussed in detail in his deposition testimony.” Defendants also maintain that Dr. Gabaeff’s

notes do not contain an opinion that “any deviation identified by Nurse DeBoer or Nurse Harris 

proximately caused injury” to decedent.

¶ 53 In response to plaintiff’s specific allegedly qualifying disclosures, defendants state:

1. Dr. Gabaeff’s statement defendant Jasper placed decedent in the hallway 

without getting an appropriate history and recognizing sepsis is a statement about 

conduct (i.e. deviation from the standard of care) and not causation; Dr. Gabaeff 
1-19-1420 

- 15 - 

is not qualified to offer an expert opinion as to whether Jasper’s conduct fell 

below the standard of care; and, regardless, Dr. Gabaeff disavowed any 

commentary on Jasper’s deviation from the standard of care.

2. Dr. Gabaeff was not aware of Nurse Harris’s opinions regarding defendant 

Jasper’s deviations from the standard of care—Nurse Harris being plaintiff’s 

standard of care expert as to defendant Jasper—nor did plaintiff disclose Dr. 

Gabaeff’s opinion as to how defendant Jasper’s conduct proximately caused the 

death; thus, “the trial court correctly concluded that any opinion *** about how 

the alleged deviations by [defendant] Jasper as testified to by Nurse Harris caused 

injury would violate Rule 213.

3. Although plaintiff did disclose Dr. Gabaeff’s opinion as to how defendant 

Schreiber’s conduct proximately caused the death, being specifically that “a welltrained provider would have recognized[decedent] as a [ESI] category 1 

immediately based on a complete history and her presenting symptoms,” the 

conduct on which Dr. Gabaeff relied was not the deviation from the standard of 

care that Harris testified about at trial that, had defendant Schreiber learned 

decedent’s history of steroid use and splenectomy, the appropriate ESI was 2; 

“[n]or did Dr. Gabaeff testify at trial that had [decedent] been categorized an ESI 

2 or had the history of splenectomy and steroid use been communicated to a 

reasonably careful physician *** that would have resulted in a *** better 

outcome.” 

4. “Dr. Gabaeff never properly disclosed any opinion as to how a more complete 

history revealing
1-19-1420 

- 16 - 

a. a splenectomy

b. splenectomy scar or

c. steroid use

would have impacted a reasonably careful physician’s treatment of [decedent.]” 

5. Plaintiff’s counsel did not “remedy any defects regarding causation” 

during Dr. Gabaeff’s deposition.

¶ 54 In reply, plaintiff argues (1) Dr. Gabaeff did not review Nurse Harris’ testimony and (2) 

Dr. Gabaeff’s statement that he was not offering an opinion as to whether defendant Jasper’s 

conduct was a deviation from the standard of care has “no bearing on whether [Dr. Gabaeff] 

could give causation opinions” as to defendant Jasper (or defendant Schreiber). This is because, 

according to plaintiff, under Northern Trust Co. v. University of Chicago Hospitals and Clinics, 

355 Ill. App. 3d 230, 242 (2004), Dr. Gabaeff was the only witness qualified to give an expert 

opinion as to whether the defendant nurses’ negligence was a proximate cause of the death. 

Furthermore, plaintiff argues that Dr. Gabaeff’s failure to review Nurse Harris’s testimony is not 

dispositive because Dr. Gabaeff’s review of decedent’s medical records provided “a proper basis 

for [Dr. Gabaeff’s] causation opinions regarding [defendant] Jasper’s conduct.” Further, Dr. 

Gabaeff could form an opinion as to whether defendant Jasper’s conduct was a proximate cause 

of death from reviewing decedent’s medical records. As for defendant Schreiber, plaintiff argues 

that Dr. Gabaeff’s opinion is based on the same conclusion stated by Nurse DeBoer: that 

defendant Schreiber mistriaged decedent because defendant Schreiber did not obtain a complete 

medical and surgical history.
1-19-1420 

- 17 - 

¶ 55 Plaintiff also claims that Dr. Gabaeff’s causation opinion was included in his report 

provided in discovery and, at the very least, his opinion is a logical corollary to his opinions in 

his report. Plaintiff specifically relies on the following statements in Dr. Gabaeff’s report:

1. “Decedent’s demise started when she was mis-triaged on arrival a resultant 

catastrophic effect

2. Using a conventional triage scale *** [decedent] was mischaracterized as a 

Triage category 3; a mistake that was most responsible for her death 

[(emphasis in original)].

3. Her correct triage category was at least 2 at first and 1 within a short time. In 

my opinion, a well-trained provider would have recognized her as a category 

1 immediately based on a complete history and her presenting symptoms and 

in need of immediate treatment ***.” 

The conclusion to Dr. Gabaeff’s report reads, in pertinent part, as follows:

 “Ms. Jones if treated in a timely manner would have had a > 50% chance 

of being alive today. Mistriage followed by inattention to her rapidly changing 

status, and a failure to follow the hospital’s own guidelines, kept her from the 

immediate basic care she needed in the timely manner, which is the standard of 

care for sepsis. The course of events validated the worth of the principle of timely 

aggressive care with large amounts of IV fluids (fluid resuscitation) and large 

doses of strong, well accepted antibiotics that should be used to treat sepsis. Poor 

decision making, mid-stream, based on lack of attention to details that were 

available and inadequate early involvement of a capable physician provider, lead

to a state of inevitable death that was not present when she arrived in the ED 7 
1-19-1420 

- 18 - 

hours before her death. The hospital mis-triage, the failure to be seen in a timely 

manner, the NP inability to recognize and communicate, effectively with the 

provider and the providers ill-informed and poor decision making at the critical 

moments, constitutes gross negligence in failing to meet the standard of care in 

this life threatening situation.” (Emphases added.)

¶ 56 Plaintiff contends that Dr. Gabaeff’s notes state his opinions regarding defendant nurse’s 

conduct and that these “opinions were the foundation of Dr. Gabaeff’s opinions [regarding 

causation,] which were also supplied at the doctor’s deposition.” 

¶ 57 At the hearing the court held regarding whether to allow plaintiff to recall Dr. Gabaeff to 

testify concerning his opinion as to whether defendant nurses’ conduct was a proximate cause of 

the death, the parties began with discussing Dr. Gabaeff’s report and the conclusions stated 

therein. Defendants’ attorney acknowledged that during his deposition, with regard to “all of the 

opinions” in his report, it was Dr. Gabaeff’s opinion that “the deviations from the standard of 

care proximately caused the death.” Defendants’ attorney complained that the deviations Dr. 

Gabaeff discussed during the deposition, however, concerned only Nurse Schreiber and Dr. 

Dissanayake, not Nurse Jasper and, for that reason, anything Dr. Gabaeff would testify about 

concerning whether “anything Jasper did or didn’t do caused or contributed to any injury or 

damage *** is outside the bounds of Rule 213.” Plaintiff’s attorney pointed out that Dr. 

Gabaeff’s report stated “the deviations from the standard of care by all three [defendants] 

proximately caused her death;” and the trial court agreed that in paragraph 53 of the report Dr. 

Gabaeff wrote that the deviation as to defendant Jasper was that Jasper “did not take a full 

history. It was mistakenly assigned, and obviously he didn’t have enough information to 
1-19-1420 

- 19 - 

communicate to Dr. [Dissanayake.]” The trial court also agreed that Dr. Gabaeff “said in his 

deposition that the items in his report proximately caused the death.” 

¶ 58 However, plaintiff’s counsel then informed the trial court how she planned to proceed if 

allowed to recall Dr Gabaeff to testify. Plaintiff’s counsel represented to the court that she 

would read or summarize expert witness Nurse Harris’s testimony to Dr. Gabaeff, then ask Dr. 

Gabaeff if the deviations Nurse Harris testified to, which were just read to him, were a proximate 

cause of the death. It was at that point defendants’ attorney objected that “[t]o give him that 

question and to elicit an opinion based on that question is a new opinion.” Defense counsel 

argued “[h]e can’t do that. That’s for the first time at trial an undisclosed opinion.” The trial 

court agreed with defendants’ counsel that Dr. Gabaeff would have to “stick to what it says in his 

deposition or report.” The trial court noted that Dr. Gabaeff could not offer an opinion as to the 

nurses’ deviations from the standard of care and stated: “he’s acknowledged what the deviations 

were in his report, and those are the only ones he can link up; otherwise it’s a new opinion.” 

Defendants’ attorney argued that “all that’s in that report is an issue of communication” between 

Jasper and Dr. Dissanayake. The court responded that, given the court’s ruling, “there is only 

one criticism” Dr. Gabaeff could offer a causation opinion about—that Jasper “didn’t 

communicate [decedent’s history to Dr. Dissanayake] because [Jasper] didn’t know it;” or in 

other words defendant Jasper “failed to *** acquire a complete history of [decedent] and 

communicate that to Dr. Dissanayake.” 

¶ 59 Turning to defendant Schreiber, defendants’ attorney argued that the basis for Dr. 

Gabaeff’s opinion that defendant Schreiber’s conduct was a proximate cause of the death was 

“her failure to recognize the signs and symptoms of SIRS and sepsis in triage [which “should 

have led to an ESI-2.”].” Defendants argued that because the standard of care expert, DeBoer,
1-19-1420 

- 20 - 

did not opine that same failure was a deviation from the standard of care, the proffered opinion 

from Dr. Gabaeff regarding defendant Schreiber was either a new opinion or a new basis for his 

opinion. Defendants admitted that the basis for Dr. Gabaeff’s opinion as to defendant Schreiber 

was her failure to obtain a “complete history” of decedent, but defendants argued Dr. Gabaeff 

never before disclosed that he meant obtaining a “complete history” included learning that the 

decedent had previously had a splenectomy and was taking steroids. The trial court recognized 

that this dispute raised the question of whether “complete history” is “sufficient notice of what 

he’s saying” for purposes of Rule 213. The court found that Dr. Gabaeff did not state that a 

“complete history” would have included finding out that the decedent had a splenectomy or was 

on steroids either in his report or in his deposition and that plaintiff’s attorney could point to no 

such language. Plaintiff’s counsel responded by stating that in her reexamination of Dr. Gabaeff 

she would only ask Dr. Gabaeff about his opinions based on defendant Schreiber’s failure to 

obtain a “complete history” (apparently without asking him to explain what that means) and her 

mistriage of decedent.

¶ 60 Following a recess, the trial court returned to the question regarding defendant Jasper. 

The trial court noted its belief that the two deviations from the standard of care on which Dr. 

Gabaeff based his proximate cause opinion as to Jasper were in paragraph 53 of his report but 

that Dr. Gabaeff “took that back.” Plaintiff disagreed with the trial court’s characterization of 

Dr. Gabaeff’s deposition testimony as rescinding the bases for his opinion that defendant 

Jasper’s conduct was a proximate cause of death. Plaintiff argued, in part, that Dr. Gabaeff was 

“basing his causation opinion on the facts of what happened in the case.” The trial court ruled 

that the “standard of care has to come through Harris and DeBoer” to provide the basis for Dr. 

Gabaeff’s opinion that a deviation from the standard of care was a proximate cause of death and 
1-19-1420 

- 21 - 

that Dr. Gabaeff failed to say that obtaining a “complete history” from the decedent “would have 

discovered the splenectomy, the steroid use ***;” therefore, the court would not allow Dr. 

Gabaeff to “testify as to causation as to either Schreiber or Jasper.” Plaintiff’s counsel argued 

that Dr. Gabaeff disclosed prior to trial that the bases of his opinions were the failure to obtain a 

“complete history” and the mistriage of decedent. The trial court stated that, nonetheless, Dr. 

Gabaeff had to read a standard-of-care expert’s report stating what “complete history” meant to 

be able to testify. Defendants’ attorney informed the court and conceded that Dr. Gabaeff did 

read DeBoer’s report and, in DeBoer’s report, DeBoer stated that a complete history would have 

found out decedent had a splenectomy and was on steroids. The trial court then acknowledged

that Dr. Gabaeff talked in his deposition about defendant Schreiber’s failure to obtain a complete 

history. Further, DeBoer testified that Schreiber’s mistriage “was the failure to get the history of 

splenectomy and steroid use.” 

¶ 61 Plaintiff argued that Rule 213 requires the expert to disclose the basis for his opinion, and 

that the opinion disclosed in this case is based on the mistriage that resulted from the failure to 

obtain a “complete history” which is “sufficient to put them on notice of what his theory is.” 

Defendants countered that there is nothing in the disclosures or deposition “about anything other 

than the signs of SIRS in triage” and the mistriage as a category 3. The court acknowledged that 

the issue came down to whether saying “complete history” without elaboration was a sufficient 

disclosure under Rule 213. The trial court found it was not, and it also found that Dr. Gabaeff’s 

notes were not disclosures under Rule 213. Defendants admitted that Dr. Gabaeff produced his 

notes at his deposition but argued the notes are not part of plaintiff’s Rule 213 disclosure. The 

trial court stated that the notes are from Dr. Gabaeff’s review of DeBoer’s testimony but the trial 

court pointed out that Dr. Gabaeff did not state in his notes that he agreed with DeBoer. Plaintiff 
1-19-1420 

- 22 - 

argued the notes, which were disclosed at the deposition, explain what was missing from the 

“complete history.” Plaintiff argued:

 “He says in the deposition that the items in my report were the proximate 

cause. In this report he says failure to take a complete history. In his supporting 

documents which everybody has, he writes specifically that she didn’t know she 

didn’t have a spleen and she didn’t know that she was on Prednisone because she 

never asked. That’s right here. So their claim that they didn’t know is not true. 

It’s right in the documents that they were given.” 

¶ 62 The trial court rejected plaintiff’s argument and stood on its ruling denying plaintiff’s 

request to recall Dr. Gabaeff to testify as to whether the nurse defendants’ conduct was a 

proximate cause of the death in this case. The trial court reasoned that plaintiff’s standard of care 

experts testified to deviations from the standard of care on which Dr. Gabaeff’s opinions are not

based and, because Dr. Gabaeff failed to disclose the basis of his opinion before trial, any such 

testimony would constitute a new opinion not previously disclosed. 

¶ 63 For the following reasons, we hold that the trial court committed reversible error by 

finding that plaintiff’s pretrial disclosures were not sufficient under Rule 213 or that Dr. Gabaeff 

failed to disclose the bases of his opinions as to proximate cause before trial. “One of the 

purposes of Rule 213 is to avoid surprise.” Sullivan, 209 Ill. 2d at 109-10; Steele, 2013 IL App 

(3d) 110374, ¶ 92 (“The purpose of discovery rules, governing the ‘timely disclosure of expert 

witnesses, their opinions, and the bases for those opinions[,] is to avoid surprise and to 

discourage strategic gamesmanship.’ ”). “An expert’s testimony is limited to the fair scope of 

opinions disclosed during discovery.” (Emphasis added); Sinclair v. Berlin, 325 Ill. App. 3d 

458, 470 (2001), citing Lucht v. Stage 2, Inc., 239 Ill. App. 3d 679, 692 (1992) (“An expert is not 
1-19-1420 

- 23 - 

limited to the exact words used in discovery, whether interrogatories or deposition, but to the 

‘fair scope’ of the opinions disclosed.” (construing former Illinois Supreme Court Rule 220(d) 

(134 Ill.2d R. 220(d)). 

¶ 64 In Spaetzel v. Dillon, 393 Ill. App. 3d 806 (2009), this court addressed a plaintiff’s 

argument that the trial court abused its discretion in allowing a doctor to testify as to his opinion 

interpreting certain radiographic films because allegedly that opinion “had not been disclosed in 

answers to interrogatories or in depositions and, therefore, the plaintiffs were prejudiced by such 

surprise.” Spaetzel, 393 Ill. App. 3d at 812. The evidence in that case was that the defendants’ 

Rule 213 disclosures stated that the basis of the doctor’s opinion included “all the relevant 

medical records and diagnostic studies.” Id. at 813. In his deposition, the doctor testified he had 

“reviewed X-rays from several periods of time.” Id. Nonetheless, the plaintiffs argued those 

disclosures did not put them on notice that defense counsel was going to display a blow up of a 

radiographic film and then elicit the doctor’s opinion of those blown-up films or his opinion as to 

what a different film suggested about the condition that afflicted the plaintiff in that case. Id. 

This court disagreed. Id. This court found that defendants had disclosed that the expert had 

reviewed the radiographic studies, disclosed the “general opinions” the doctor would testify to, 

and, specifically, disclosed that the doctor would testify what the second radiographic film 

suggested about the condition at issue. Id. In reaching that conclusion, this court relied on both 

the doctor’s answers to interrogatories and deposition testimony. See id. We held that the 

pretrial disclosures were sufficient and “the particular opinion *** regarding blown-up pictures 

of the CT scans, were permissible as an elaboration on, or logical corollary to, the originally 

revealed opinion.” Id.
1-19-1420 

- 24 - 

¶ 65 Later, relying on the decision in Spaetzel, this court addressed a plaintiffs’ argument that 

the defense expert’s pretrial disclosures “did not reveal the specific basis for their opinion, thus 

rendering their testimony violative of Rule 213.” Jones v. Beck, 2014 IL App (1st) 131124, ¶ 17. 

This court disagreed, holding that based on a review of the record, the experts’ opinions “were 

rather clearly disclosed.” Id. at ¶ 18. This court found in Jones, just as in Spaetzel, “the 

defendants disclosed the ‘general opinions’ that their defense expert would testify to during 

trial.” Id., citing Spaetzel, 393 Ill. App. 3d at 813. The disclosure of the experts’ “general 

opinions” was “sufficient to put the plaintiffs on notice regarding the details that emerged.” Id. 

¶ 18. 

¶ 66 The Jones court separately addressed the plaintiffs’ argument that the pretrial disclosures 

contain no mention that a certain action (in other words, the defendant’s alleged deviation from 

the standard of care) would have prevented the injury (in other words, proximate cause). Id. 

¶ 19. We found that contention “meritless.” Id. Instead, we held that the “description of the 

anticipated trial testimony clearly put [the] plaintiffs on notice” that the experts would testify the 

alleged deviation was not a proximate cause of the injury. Id. (“the description of the anticipated 

testimony clearly put [the] plaintiffs on notice that Soden and Beck would testify to the 

inefficacy of the NG tube”). In that case, the pretrial disclosure was only that the experts were 

expected to testify that no deviation contributed to cause the injury. Id. This court held, “[b]ased 

on these disclosed opinions,” the “testimony regarding compliance with the standard of care 

[and] *** opinions regarding the absence of any proximate causation *** were all logical 

corollaries of the pretrial disclosures.” Id. In reaching this holding, we noted that Rule 213 “is 

intended to be a shield to prevent unfair surprise but not a sword to prevent the admission of 
1-19-1420 

- 25 - 

relevant evidence on the basis of technicalities. [Citations.]” (Internal quotation marks omitted.) 

Id. ¶ 18. 

¶ 67 In Foley v. Fletcher, 361 Ill. App. 3d 39, 47 (2005), this court held that the expert’s 

testimony did not violate Rule 213 where the testimony “did not advance a new theory of 

negligence or new reasons for his opinion.” Foley, 361 Ill. App. 3d at 48. Later, in AguilarSantos v. Briner, 2017 IL App (1st) 153593, we rejected the defendant’s argument that the 

plaintiff failed to disclose the expert’s proximate cause testimony. We accepted that the expert’s 

pretrial disclosures did not “specifically state” that the expert would provide the complained-of 

proximate cause opinion, but we held that “an expert’s trial testimony does not necessarily 

violate Rule 213 if it is ‘an elaboration on, or a logical corollary to, the originally revealed 

opinion.’ [Citation.]” Id. at ¶ 50. 

¶ 68 In this case, Dr. Gabaeff’s disclosures were as follows: 

 “(i) Subject(s)/Topic(s): Dr. Gabaeff will testify as to the facts and 

circumstances surrounding the treatment of the Decedent in the UIC ER on the 

night of the occurrence in question, based on his review of the pertinent medical 

records from the same; ***; and as to his opinion that the aforementioned 

deviations by this and the other defendants proximately caused the Decedent’s 

death.

(ii) Conclusions and Opinions: UIC Emergency Department professionals 

*** deviated from standard of care by one or more of the following: mistriaged 

patient as a category 3 and assigned to ‘fast track;’ failure to treat in a timely 

manner; demonstration of inattention to patient’s changing status; failure to 

communicate within the Emergency Department and to follow hospital guidelines. 
1-19-1420 

- 26 - 

Had the patient been treated in a timely manner she would have had a greater than 

50% chance of surviving.” (Emphases added.)

¶ 69 In his disclosed expert report, Dr. Gabaeff identified a list of events containing 58 items

which he stated were below the standard of care and represented gross negligence. Relevant to 

defendant nurses were the following:

“1. Ms. Jones[‘][] demise started when she was mis-triaged on arrival a resultant 

catastrophic effect. 

2. *** Ms. Jones was mis-characterized as a Triage category 3; a mistake that 

was most responsible for her death ***

6. Her correct triage category was at least 2 at first and 1 within a short time. In 

my opinion, a well-trained provider would have recognized her as a category 1 

immediately based on a complete history and her presenting symptoms.

7. At triage she was designated triage category 3 ***

9. On closer exam of her med record at triage she already had fulfilled American 

College of Chest Physician’s criteria for possible sepsis. This is referred to as the 

Systemic Inflammatory Response Syndrome (SIRS), with an elevated temperature 

and increased pulse.

10. Later workup, including blood drawn in triage, showed she fulfilled a third 

criteria, and in short order the 4th. ***

13. The condition she had (sepsis) is rapidly progressive and required ASAP 

intervention. This is a foundational principle in EM. Treatment is immediate 

high volumes of fluids (>2 liter or more in large people as AFAP; ~ over 30 

minutes) to combat shock and 2 high dose strong antibiotics.
1-19-1420 

- 27 - 

14. Delays of as little as few hours are the difference between life or death, as 

this case demonstrates. ***

20. Ms. Jones, in this case, remained [in] the hall for 3 hours, was not seen by 

any provider except a nurse that rechecked her temperature only at about [8:27 

p.m.].

21. In triage she was given Tylenol to lower temp and it worked. Unfortunately, 

with Tylenol, any decrease in temp becomes an unreliable indicator of actual 

improvement in the underlying condition that can lead to a false sense of what is 

really happening.

22. During the 3 hours from 6p to 9p, the lack of proper attention by a physician 

violated the hospital own guidelines for triage 3 that dictates that the patient is to 

be seen by a physician (not an NP or an RN) in 30 minutes.

23. At around 9pm by accident (or luck), the PA assigned to her happened to 

walk by her in the hall and she stopped him, not knowing who he was, and 

reported she was cold (another finding in shock). He, laying eyes on her, seeing 

she was ill, brought her into a fast track room for the first time, 3 h after arrival[.] 

* * * 

29. At that time the patient was still awake but talking slower. The MD did not 

seem aware that the NP had ordered strong narcotic medications that were given 

at [8:40 p.m.] and [9:10 p.m.] Both these doses would make her sleepy (altered 

mental status) and can lower BP which would make things actually worse. ***

53. In a note written by the NP, it is stated that the MD, informed the patient was 

in the ED, told the NP to put the patient in the hall. He did this not having 
1-19-1420 

- 28 - 

examined her at all and apparently not fully aware of the history which was clear 

for infection and sepsis, prior to full shock setting in. ***.” (Emphases added.) 

¶ 70 The report’s conclusions stated, 

“Mistriage followed by inattention to her rapidly changing status, and a failure to 

follow the hospital’s own guidelines, kept her from the immediate basic care she 

needed in the timely manner, which is the standard of care for sepsis. *** Poor 

decision making, mid-stream, based on lack of attention to details that were 

available *** lead to a state of inevitable death that was not present when she 

arrived in the ED 7 hours before her death. The hospital mis-triage, ***, the NP 

inability to recognize and communicate, effectively with the provider ***, 

constitutes gross negligence in failing to meet the standard of care in this life 

threatening situation.” (Emphasis added).

¶ 71 Dr. Gabaeff testified during his deposition that he believed Schreiber deviated from the 

standard of care by assigning Jones an ESI 3 versus a 2. Dr. Gabaeff generally testified that 

“[Jones] fulfilled the SIRS criteria in triage one” and discussed Jones’ other symptoms which he 

concluded were red flags of septic shock present upon Jones’ arrival at the emergency 

department. At the deposition, defendants’ attorney asked Dr. Gabaeff about his notes. The 

parties marked all Dr. Gabaeff’s notes as a group exhibit. 

¶ 72 We hold that Dr. Gabaeff’s proposed testimony that the nurse defendants’ conduct was a 

proximate cause of the death in this case “did not advance a new theory of negligence or new 

reasons for his opinion.” Foley, 361 Ill. App. 3d at 48. Plaintiff’s pretrial disclosures clearly 

disclosed Dr. Gabaeff’s opinion that deviations from the standard of care by “the other 

defendants,” i.e., defendant nurses, “proximately caused the Decedent’s death.” Based on that 
1-19-1420 

- 29 - 

disclosure we find plaintiff disclosed “the ‘general opinions’ that [her] expert would testify to 

during trial.” Jones, 2014 IL App (1st) 131124, ¶ 18, citing Spaetzel, 393 Ill. App. 3d at 813. In 

addition to disclosing Dr. Gabaeff’s opinion that the nurse defendants’ conduct was a proximate 

cause of the death, the pretrial disclosures adequately revealed the bases for Dr. Gabaeff’s 

opinions as being specifically the failure to obtain a complete medical history and to properly 

triage the patient. The disclosure of the expert’s “general opinions” was sufficient to put the 

defendants on notice regarding the details that emerged. See id. Dr. Gabaeff’s proximate cause 

testimony was consistent with the disclosures contained in the plaintiff’s Rule 213(f) answers to 

interrogatories and the disclosures in the exhibit to his deposition testimony. See Aguilar-Santos, 

2017 IL App (1st) 153593, ¶ 57. 

¶ 73 On appeal, defendants argue “Dr. Gabaeff’s Rule 213 answers and report *** only speaks 

to the negligence of the nurses and states nothing about how the purported deviations by the 

nurses proximately caused Ms. Jones’ death.” However, any alleged deficiencies in this regard

would go to the weight of the evidence, not its admissibility. See Aguilar-Santos, 2017 IL App 

(1st) 153593, ¶ 57 (holding that a party’s pretrial disclosures were sufficient where pretrial 

disclosure of proximate cause opinion was not expressly stated but could be gleaned from the 

statement of general opinion as to proximate cause and written records provided in discovery); 

see also Pack, 2019 IL App (1st) 182447, ¶¶ 87-89. We also find defendants’ argument 

unpersuasive where, based on the disclosed opinions, testimony “regarding compliance with the 

standard of care [and] *** proximate causation *** were all logical corollaries of the pretrial 

disclosures.” See Jones, 2014 IL App (1st) 131124, ¶ 19. 

¶ 74 Furthermore, defendants argue that Dr. Gabaeff’s notes were not “discussed in detail in 

his deposition testimony.” Even if we accept that argument as a proper characterization of the 
1-19-1420 

- 30 - 

deposition, a properly disclosed opinion is not invalidated simply because counsel fails to make 

detailed inquiry into the disclosed basis for that opinion at the deposition. See Pack, 2019 IL 

App (1st) 182447, ¶¶ 87-89. 

¶ 75 We find Wilbourn v. Cavalenes, 398 Ill. App. 3d 837 (2010), on which defendants rely, 

distinguishable. In that case, the defendant doctor used a metal plate to repair the broken femur 

of a patient. The plate failed one month after treatment. The expert opined that the wrong 

medical device failed. At issue was whether a broad plate or a narrow plate was used. Wilbourn, 

398 Ill. App. 3d at 850-51. The disputed subject of disclosure was the basis for the expert’s 

opinion that the wrong device was used, not whether it was the wrong device or that it had failed. 

See id. The plaintiff’s pretrial disclosures in that case stated that the expert knew the wrong 

device (a narrow plate instead of a broad plate) was used based on the appearance in x-rays 

taken. Id. at 851. At trial, the expert stated that he had never seen a broad plate fail within a 

month after implantation. We affirmed the trial court’s order striking testimony that a broad

plate would not have failed in a month. We held the basis for the testimony that the expert knew 

the wrong device was used had to be elicited by the proponent of the expert or placed in 213 

responses. Id. In Wilbourn, the defendants were “surprised” by his testimony that he knew 

which device was used, not only due to its appearance but also because a broad plate would not 

have failed within a month. In this case, however, the pretrial disclosures put defendants on 

notice that Dr. Gabaeff would testify that specific conduct by nurse defendants was a proximate 

cause of the death. We find defendants were not surprised by Dr. Gabaeff’s testimony within the 

meaning of the Rule. Sullivan, 209 Ill. 2d at 109-10. 

¶ 76 For the foregoing reasons, we find the trial court abused its discretion in denying 

plaintiff’s request to recall Dr. Gabaeff to testify concerning his opinion about whether nurse 
1-19-1420 

- 31 - 

defendants’ previously disclosed deviations from the standard of care were a proximate cause of 

the death. We find that there was sufficient evidence in the record of the deviations from the 

standard of care on which Dr. Gabaeff relied to provide an adequate foundation for his testimony

on that subject. In re Saline Branch Drainage District, 19 Ill. App. 3d 125, 132 (1974) (“The 

rule is clear that one test of admissibility of the opinion of an expert witness is whether there is 

sufficient evidence in the record to act as a foundation of the expert’s opinion.”). 

¶ 77 In this case, DeBoer testified that Schreiber deviated from the standard of care by (1) not 

obtaining a complete medical and surgical history from Jones; and (2) based on that failure, did 

not assign Jones a level 2 ESI categorization at triage and instead assigned her a level 3 ESI. 

Harris testified that Jasper deviated from the standard of care when he failed to take an adequate 

history from Jones and provided an ineffective report to the attending physician. We find the

opinions of these other two experts to be consistent with Dr. Gabaeff’s opinion that the delay 

occasioned by the acts or omissions of the nurses proximately caused Jones’ death. 

¶ 78 Under Sullivan, 209 Ill. 2d at 112-24, Dr. Gabaeff is not entitled to offer an opinion to the 

jury about what standard of care applies to the nurses or whether specific acts or omissions by 

the nurses constituted negligence. However, Dr. Gabaeff offered an opinion before trial and was 

prepared to testify that the delay in Jones’s treatment while in the nurses’ care, before she 

reached Dr. Dissanayake, resulted in Jones not being offered appropriate and timely medical 

intervention to avoid death. Dr. Gabaeff was prepared to testify that the fact that Jones went 

untreated for several hours was the proximate cause of her death. Setting aside any specific 

criticisms as to what the nurses did or should have done, it is Dr. Gabaeff’s opinion that the 

overall delay in treatment put Jones on the path to her demise—that by the time Dr. Dissanayake 

began treating Jones, much of the damage was already done. Dr. Gabaeff is clearly qualified to 
1-19-1420 

- 32 - 

offer an opinion that the delay in rendering the appropriate treatment to Jones caused her death.

The factfinder can only make a fair assessment of liability in this case by hearing Dr. Gabaeff’s

testimony about proximate cause alongside the opinions of DeBoer and Harris who are the 

experts competent to testify about the applicable standard of care and whether the nurse 

defendants breached that standard.

¶ 79 The rule in Sullivan ensures that a testifying expert has expertise in dealing with the 

patient’s medical problem and treatment and that the allegations of negligence are within the 

expert’s knowledge and observation. Wingo by Wingo v. Rockford Memorial Hospital, 292 Ill. 

App. 3d 896, 906 (1997). When the allegations do not concern a specific nursing procedure but, 

rather, a general observation of the applicable field of medicine, then the allegations may be well 

within the testifying doctor’s knowledge and experience. Id. “As a general rule, ‘[e]xpert 

testimony is admissible if the proffered expert is qualified by knowledge, skill, experience, 

training, or education, and the testimony will assist the trier of fact in understanding the 

evidence.’ ” Johnson v. Johnson, 386 Ill. App. 3d 522, 544-45 (2008). Here, Dr. Gabaeff is 

qualified to testify that a delay in treating Jones before she reached a doctor proximately caused 

her death.

¶ 80 It is true that Dr. Gabaeff referred in his report to negligent acts or omissions by the 

nurses that contributed to the delay in treatment, and defendants are correct that such testimony

would not be admissible under Sullivan. The court would have been well within its discretion to

disallow that portion of any testimony Dr. Gabaeff offered. But it does not follow that all of Dr.

Gabaeff’s testimony on the delay in treatment should have been barred. He clearly had the 

qualifications to opine that one of the proximate causes of death was a significant delay in

treatment before the patient reached Dr. Dissanayake, even if he could not opine as to who was,

or was not, to blame for that delay. And that opinion was disclosed repeatedly throughout his 

report; indeed, Dr. Gabaeff wrote that the delay in treatment was the most significant cause of 

Jones’s death. By disallowing all of this testimony about delay in treatment, including testimony

that was disclosed well in advance and on which Dr. Gabeff unquestionably had the qualification

to opine, the trial court went too far. And in so doing, the trial court barred expert testimony that

established proximate cause against the nurses for their alleged delay in getting adequate

treatment for Jones, leaving plaintiff defenseless against a motion for directed verdict. The error,

in other words, was anything but inconsequential; it made a defense verdict all but inevitable. 

¶ 81 Dr. Gabaeff clearly disclosed that the delay in rendering medical intervention to Jones 

proximately caused her death. See, e.g., supra ¶¶ 55, 70-71. We reject defendants’ arguments 

and the trial court’s ruling that Dr. Gabaeff’s proposed testimony in this regard was a new 

opinion or was otherwise not disclosed prior to trial. Based on the totality of the pretrial 

disclosures, defendants would not in any way be surprised to have testimony about the delay in 

treatment constituting proximate cause admitted at trial. See Jones, 2014 IL App (1st) 131124, ¶ 

18, Zickuhr v. Ericsson, Inc., 2011 IL App (1st) 103430, ¶¶ 84-85. 

¶ 82 Having found that the trial court erred when it barred Dr. Gabaeff’s testimony on 

proximate cause, we must determine if the error warrants reversal. “[I]t is axiomatic that error in 

the exclusion or admission of evidence does not require reversal unless one party has been 

prejudiced or the result of the trial has been materially affected. [Citation.]” (Internal quotation 

marks omitted.) Spaetzel, 393 Ill. App. 3d at 814. In this case, the exclusion of Dr. Gabaeff’s 

opinions as to proximate cause prejudiced plaintiff in her case against the nurse defendants. 

Without the pertinent testimony from Dr. Gabaeff, plaintiff was unable to submit evidence in 

support of an essential element of her claim. The trial court granted a directed verdict in the 
1-19-1420 

- 34 - 

nurse defendants’ favor on the basis that plaintiff failed to produce evidence on the issue of 

proximate cause. Dr. Gabaeff’s testimony would have been sufficient to make a prima facie

showing of proximate cause sufficient to defeat a motion for a directed verdict. Because Dr. 

Gabaeff’s proposed testimony on proximate cause relating to the nurses’ actions should have 

been allowed, no directed verdict in favor of the nurse defendants should have been entered. 

Accordingly, plaintiff is entitled to a new trial on her claims against the nurse defendants.

¶ 83 Plaintiff contends that if we find she is entitled to a new trial on her claims against the 

nurse defendants, we should likewise find that she is entitled to a new trial on her claims against 

Dr. Dissanayake. Plaintiff’s claims against Dr. Dissanayake were submitted to the jury, and the 

jury returned a finding of no liability. Plaintiff argues that “[o]nce the trial court directed a 

verdict in favor of the nurses, it was all but decided that the doctor could not have been 

negligent.” We reject plaintiff’s assertions regarding the verdict in favor of Dr. Dissanayake. 

¶ 84 Plaintiff did not raise the issue that the directed finding resulted in an unfair assessment 

of her claims against Dr. Dissanayake in her posttrial motion. Following a jury trial, a party 

claiming an error in the proceedings must raise the claim in a posttrial motion in order to 

preserve it for review. Ill. S. Ct. R. 366(b)(2)(iii) (eff. Feb. 1, 1994) (West 2018); Ellig v. Delnor 

Community Hospital, 237 Ill. App. 3d 396, 403 (1992). Here, plaintiff raised the issue for the 

first time in a reply brief. 

¶ 85 Moreover, plaintiff was permitted to introduce all the evidence she sought to introduce at 

trial as it pertained to Dr. Dissanayake’s potential liability. The jury was provided with all the 

evidence plaintiff submitted regarding her claims against Dr. Dissanayake, and the jury 

deliberated and returned a verdict of no liability in the doctor’s favor. Plaintiff does not argue 

that the verdict in favor of Dr. Dissanayake was against the manifest weight of the evidence. 
1-19-1420 

- 35 - 

Plaintiff’s speculation about what potential impact the directed verdict had on the jury’s 

deliberations is insufficient to carry her burden to entitle her to a new trial on the claims against 

Dr. Dissanayake. With plaintiff having failed to demonstrate any prejudice, we hold that the 

judgment of no liability entered in favor of Dr. Dissanayake stands. 

¶ 86 CONCLUSION

¶ 87 For the foregoing reasons, the judgment of the circuit court of Cook County is affirmed in 

part and reversed in part. The judgment of no liability in favor of defendant Dr. Dissanayake is 

affirmed. The directed verdict entered in favor of defendants Mark Jasper and Elisabeth 

Schreiber is reversed and the case is remanded for a new trial as to the claims against those 

defendants only. 

¶ 88 Affirmed in part, reversed in part, remanded for further proceedings.
