I. INTRODUCTION1

Defendants move to exclude the expert testimony of two doctors, Dr. Darlene

Calhoun and Dr. Wayne Ross, regarding their testimony as to the conscious pain and

suffering of A.B. before his death.2 Defendants assert both doctors intend to testify

as to conscious pain and suffering without a sufficient scientific basis to support such

testimony.3 The admissibility of the doctors’ testimony regarding conscious pain

and suffering is discussed below.

II. STANDARD OF REVIEW

Delaware Rule of Evidence (“D.R.E.”) 702 governs the admission of expert

testimony. Under D.R.E. 702, expert opinion testimony is admissible provided that

the witness “is qualified as an expert by knowledge, skill, experience, training, or

education” if:

(a) the expert’s scientific, technical, or other
specialized knowledge will help the trier of the fact to
understand the evidence or to determine a fact in issue;

This Memorandum Opinion and Order references the factual and procedural
background outlined in the Court’s Memorandum Opinion and Order upon
Consideration of Defendants’ Motion for Summary Judgment, which the Court
incorporates by reference. Unless otherwise noted, defined terms are ascribed the
same meaning as in the Court’s Summary Judgment Memorandum Opinion.

Defendants have separately moved for the exclusion of the entirety of Calhoun’s and
Ross’s testimony, which the Court addresses in its separate Memorandum Opinions
and Orders. See Defs.’ Mot. to Exclude Pls.’ Expert Darlene Vasbinder-Calhoun,

(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 has applied the principles and methods to
the facts of the case.4

The burden falls on the party seeking to admit the expert testimony to show,

by a preponderance of the evidence, its admissibility under D.R.E. 702.5 “Once

expert testimony is challenged, the reviewing court must ensure that the proffered

testimony is both relevant and reliable.”6 To fulfill this duty, this Court acts as

gatekeeper, determining if “the reasoning or methodology underlying the testimony

is scientifically valid and … whether that reasoning or methodology properly can be

applied to the facts in issue.”7 In making that determination, the Court applies a five-

step test that examines whether:

(1) the witness is qualified as an expert by knowledge,
skill, experience, training[,] or education; (2) the evidence
is relevant [and reliable]; (3) the expert’s opinion is based
upon information reasonably relied upon by experts in the
particular field; (4) the expert will assist the trier of fact to
understand the evidence or to determine a fact in issue; and

(5) the expert testimony will not create unfair prejudice or
confuse or mislead the jury.8

For scientific evidence to be deemed reliable, the testimony must be rooted in

science and derived from the scientific method.9 Expert testimony is relevant when

it assists the trier of fact to understand the evidence or determining a fact in issue.

Thus, the core of a Daubert analysis is the “principles and methodology” used in

formulating an expert’s testimony, not on the expert’s resultant conclusions.10 This

Court possesses “broad latitude to determine whether any or all of the Daubert

factors are reasonable measures of reliability in a particular case.”11 “A strong

preference exists for admitting evidence that may assist the trier of fact.”12

III. ANALYSIS

From the outset, both experts offer testimony on a relevant issue. Whether

A.B. experienced conscious pain and suffering likely influences the potential award

of damages in this case. There appears to be two separate issues the doctors opine

on: (1) whether A.B. experienced conscious pain and suffering; and (2) how long

that conscious pain and suffering lasted. Both issues are relevant to a material issue

in this case—the extent of A.B.’s conscious pain and suffering.

A. CALHOUN ONLY OPINES ON THE POTENTIAL DURATION OF A.B.’S PAIN
AND SUFFERING.

Defendants posit Calhoun offers irrelevant testimony because Calhoun never

considered whether A.B. was actually conscious before he died.13 Plaintiffs argue

Calhoun’s report clearly determined A.B. would have been awake because Calhoun

detailed how A.B. would have struggled for air.14 Plaintiffs further note

Pennsylvania law does not require a decedent to be awake, but rather the decedent

must be “conscious of pain.”15

Pennsylvania law does not allow for recovery based on pain and suffering if

“the decedent is not conscious between the time of injury and the time of death.”16

The jury must determine “whether [the d]ecedent was conscious of pain, even

though his condition may have rendered him incapable of communicating that

suffering to others.”17 Plaintiffs contend this language means the jury could find

A.B. suffered even if A.B. never awoke.18 In Nye, the court held “where the decedent

is unconscious for the entire period between the time of injury and the time of death,

there can be no recovery for pain and suffering in a survival action.”19 That

statement does not suggest someone can experience pain and suffering without being

awake, as Plaintiff suggests. Further, in Williams, the court held that jury

instructions for damages were proper because both medical and lay testimony

indicated that decedent had some level of awareness and consciousness prior to his

death.20 Accordingly, testimony regarding pain and suffering should only be

admitted where the decedent awoke and had some level of awareness before his

death.

A review of Calhoun’s report shows she never explicitly determines A.B.

would have awoken once his breathing became restricted.21 Her report includes a

breakdown of symptoms associated with asphyxiation, the potential duration of

those symptoms, and an opinion that “while babies experience pain in the same way

as adults, they are noted to be far more sensitive to it.”22 Calhoun notes how A.B.

likely struggled to reposition himself and would have been gasping for air. 23

Calhoun’s decision not to opine on whether A.B. awoke does not render her

testimony on the potential length of A.B.’s pain and suffering irrelevant. Calhoun’s

depiction of the symptoms of asphyxia, as well as the potential duration of those

symptoms, provides the jury with needed context to determine the extent of A.B.’s

potential pain and suffering, if Plaintiffs can show that A.B. woke before his death.

Absent some showing that A.B. woke up, however, Calhoun’s testimony may

become irrelevant at trial. Accordingly, the Court will not exclude Calhoun’s

testimony at this juncture solely based on her failing to opine on A.B.’s

consciousness. The Court may need to revisit the admissibility of Calhoun’s pain

and suffering testimony if Plaintiffs cannot otherwise establish A.B. was awake

before his death.

B. CALHOUN’S TESTIMONY REGARDING PAIN AND SUFFERING IS
OTHERWISE ADMISSIBLE.

Defendants argue Calhoun’s testimony on pain and suffering must be

excluded because Calhoun cites an unreliable case study, the Poets case study.24

Defendants further assert none of the other authorities cited by Calhoun went

22

23

24
D.I. 166 at 16.

through peer review.25 Defendants contend reliance on peer-reviewed studies “is

necessary under Daubert.”26 Notably, Defendants do not object to Calhoun’s

methodology.

Calhoun devotes about a paragraph of her report to the findings of the Poets

case study.27 That case study went through peer review.28 Whether a study has been

subjected to peer review factors into the Court’s analysis of the reliability of the

study.29 Peer review, however, stands as one part of a “flexible inquiry” that also

considers whether the theory in question has been tested, any potential error rate

associated with the study, standards controlling the study, and whether the

underlying reasoning or methodology has attracted widespread acceptance within

the relevant scientific community.30 A study’s lack of peer review does not

necessarily render it unreliable. Similarly, a peer-reviewed study does not

necessarily qualify as reliable simply because it underwent peer review.

The Poets case study examined nine infants who died unexpectedly while

connected to a cardiorespiratory monitor.31 It did not examine infants dying from

suffocation, and it did not determine whether the infants were awake before they

died.32 The Poets case study measured “evidence that autoresuscitative methods

such as gasping occur before these deaths” and “how quickly … the heart rate

fall[s].”33 In Calhoun’s Report, she refers to the Poets case study only to discuss

how infants struggling to breathe gasp for air, how long those gasps could last, and

the corresponding effect on the infant’s heart rate.34 That data informed Calhoun’s

determination of how long A.B. potentially experienced pain and suffering.

Defendants contend there are too many differences between the circumstances

Poets evaluated and the facts of this case.35 Defendants’ concerns, including the

study’s small sample size, speak to the credibility of Calhoun’s conclusions drawn

from the Poets case study, but not the admissibility of those conclusions. Credibility

is challenged in cross-examination. Accordingly, as Defendants do not challenge

the rest of Calhoun’s pain and suffering methodology, the Court finds Calhoun’s

testimony admissible.

C. ROSS’S OPINIONS ON CONSCIOUS PAIN AND SUFFERING ARE
ADMISSIBLE.36

Unlike Calhoun, Ross explicitly concluded “[t]he transition to respiratory

failure would only serve to agitate the infant such that, even if he were asleep

originally, he would awaken to struggle and attempt to breathe.”37 Defendants argue

Ross lacks any scientific support for that opinion, reducing his conclusion to mere

speculation.38 Defendants liken Ross to the excluded expert in Jones v. Astrazeneca,

LP39 who “declined to walk through [his] methods, and instead repeatedly intoned

that [he] had reviewed all of the information [he] was supplied, applied [his] training

and experience, and put it all together.”40 Defendants lodge a similar challenge to

Ross’s conclusion that A.B. likely “experienced 60 to 90 seconds of pain and

suffering before losing consciousness.”41

36
Plaintiffs appear to argue that because other courts have admitted Ross’s
testimony, this Court should follow that lead. D.I. 207 at 20-22. The decision to
admit Ross’s expert testimony in other cases has no utility here, as those cases
concern different testimony offered by Ross which offers distinct opinions from
those in the present case.

Daubert requires this Court to “examine whether the reasoning or

methodology underlying the testimony is scientifically valid.”42 “But conclusions

and methodology are not entirely distinct from one another. Trained experts

commonly extrapolate from existing data.”43 This Court must determine if “there is

simply too great an analytical gap between the data” and Ross’s opinion.44

The Delaware Supreme Court in Norman v. All About Women, P.A 45 ruled a

doctor’s training and experience formed a sufficient basis to admit his opinion,

noting that “[m]edical literature or peer reviewed publications may be useful factors

in an appropriate case, and may be relevant to the defense in this case, but they have

no bearing on the admissibility of [the doctor’s] opinions.”46 Ross applied his

training and experience to the facts of this case. Ross based his opinion on his own

expertise, and that expertise forms a sufficiently reliable scientific basis to justify the

admission of his opinion.

Defendants further contend that the circumstances here mirror those that led

to the exclusion of expert testimony in Astrazeneca. However, in Astrazeneca, the

expert refused to explain her methodology and did not conduct a differential

diagnosis.47 Here, Ross conducted a differential diagnosis and explained during his

deposition how he determined A.B. consciously suffered at some point before his

death.48 Ross justifies his conclusion regarding how long A.B. consciously suffered

by citing to several medical texts and relying on Ross’s own training and

experience.49 Although Defendants argue those medical texts are factually

distinguishable from the facts of this case, such a distinction goes to credibility, not

admissibility.

Defendants’ contention that Ross possesses no scientific basis for his findings

appears to be more of a challenge to the credibility of Ross’s methodology. Ross’s

willingness to explain his methodology distinguishes his report from that of the

expert report excluded in Astrazeneca. Defendants’ true issue with Ross’s testimony

appears to be focused on his ultimate conclusions, rather than the approach he took

to reach those conclusions. The validity of an expert’s conclusions remains a

question for the jury provided the expert utilized a reliable methodology.50

IV. CONCLUSION

Ross utilized a reasonable methodology to determine A.B. likely experienced

conscious pain and suffering. Accordingly, Ross is permitted to testify. Ross’s

conclusions do not represent an analytical leap that is too far removed from the data

available to Ross. Further, because Ross provides some evidence that A.B.

consciously suffered, Calhoun’s failure to do so does not invalidate Plaintiffs’ claim

for conscious pain and suffering. Calhoun’s testimony is therefore relevant, as her

testimony goes to the length of time A.B. consciously experienced pain and

suffering.

“A strong preference exists for admitting evidence that may assist the trier of

fact.”51 “The Court must be satisfied that cross-examination can be vigorous.”52 The

Court is satisfied that any challenges of credibility and reliability of the data relied

Ross and Calhoun to testify as to conscious pain and suffering.

IT IS SO ORDERED.
