JUDGE DIANA HAGEN authored this Opinion, in which JUDGES MICHELE M. CHRISTIANSEN FORSTER and DAVID N. MORTENSEN concurred.
HAGEN, Judge:
¶1 Richard Taylor and Deanne Taylor (the Taylors) appeal the district court‘s decision to exclude the testimony of their causation expert in this medical malpractice case. The district court ruled that the Taylors had nоt made a threshold showing of reliability because the expert testimony was based on insufficient facts and data. Because neither the expert‘s experience nor the relevant medical literature provided a sufficient factual basis tо support the expert‘s conclusion about causation, we affirm.
BACKGROUND
¶2 The Taylors’ daughter (the patient) was diagnosed at a young age with a neurological disorder for which part of her treatment was to receive intrathecal baclofеn, a drug administered by a catheter and pumped into the thecal sac located around the spinal cord. In 2013, a neurosurgeon replaced the patient‘s pump, but not the catheter connected to the pump.
¶3 About one month latеr, the patient experienced increased spasticity in her legs, which can be a side effect of baclofen withdrawal. The patient received an oral dose of baclofen in an attempt to reduce the spasticity. A physician reassessed the patient a few hours later, determined that there had been no change of symptoms, and continued the oral dosages of baclofen. The patient also underwent an x-ray examination, which did not show any obvious problems with thе pump or catheter. The physician instructed the patient to return the following day for further evaluation.
¶4 On April 18, 2013, the patient “underwent a dye and rotator study of the pump and catheter,” but the study showed no obvious signs of a problem. Nevertheless, the physician “thought an undetected problem with the pump and catheter might still be possible.” At the same time, the patient had difficulty keeping down the oral doses of baclofen due to vomiting. After discussing the patient‘s medical history and symptoms
¶5 In early May, a few weeks after the baclofen pump and catheter were replaced, the patient began exhibiting “manic-like, psychotic behavior.” The Taylors took the рatient to a different doctor (the expert) to monitor the patient‘s baclofen treatment. Initially, the expert concluded that the patient‘s “manic-like behavior was caused by baclofen overdose” and, at the expert‘s “directiоn, all baclofen was stopped by late May 2013.” The expert later concluded that the patient‘s change in behavior was due to baclofen withdrawal rather than overdose.
¶6 The Taylors assert that the patient suffers from a permanent neurological disorder, encephalopathy, and allege that the injury was caused by baclofen withdrawal that occurred between April 18, 2013, and April 19, 2013, before the pump and catheter were replaced. The Taylors sued the University of Utah, University Hospital, University of Utah Physical Medicine and Rehabilitation Clinic, and the agents, employees, and staff employed with those institutions that were involved in the patient‘s baclofen treatment (collectively, the Defendants). To support their theory оf causation, the Taylors sought to present expert testimony at trial. The expert‘s testimony would explain that her theory of causation was the following sequence of events: “[b]aclofen withdrawal caused a metabolic disturbance, which caused encephalopathy, which produced months-long hallucinations and other abnormal behavior, resulting in or causing permanent memory and cognitive function damage.”
¶7 After deposing the expert, the Defendants filed a motion in limine to еxclude the expert‘s testimony, arguing that the testimony was not based on medical literature or her personal experience and therefore could not satisfy the threshold showing of reliability under
¶8 The district court agreed with the Defendants and excluded the expert‘s testimony. The court concluded that, because the expert “admits she has never seen [this injury] in her practice” and has failed to providе medical literature “to support the argument that encephalopathy—whether caused by a metabolic disturbance or something else—can last more than 48 hours after therapeutic levels of baclofen are restored,” she “dоes not have facts and data sufficient upon which to base her opinions or to employ her method for evaluating the causal connection in this case.”
¶9 The Taylors appeal.
ISSUE AND STANDARD OF REVIEW
¶10 The Taylors contend the district court erred in excluding the expert‘s “opinions on рroximate cause pursuant to Rule 702 of the Utah Rules of Evidence on the ground that her opinions were not based on facts and data sufficient to satisfy the threshold showing of reliability.”1 “We review a district
ANALYSIS
¶11 We are asked to determine whether the district court correctly ruled that neither the expert‘s experience nor medical literature suppоrted the expert‘s opinion regarding causation under
¶12 District courts have “wide discretion to determine whether expert testimony is admissible” under
¶13
¶14 The threshold showing of reliability can be satisfied “if the underlying principles or methods, including the sufficiency of facts or data and the manner of their application to the facts of the сase, are generally accepted by the relevant expert community.”
¶15 Here, the district court ruled that the Taylors had not made the requisite threshold showing under
¶16 The Taylors sought to offer the expert‘s opinion of causation based on her experience treating other patients with baclofеn withdrawal. Relying on her experience, the expert claimed to know that baclofen withdrawal can cause metabolic disturbances. She also claimed to know that metabolic disturbances can cause permanent neurologiсal injury, such as encephalopathy. Employing “logical deduction,” the expert concluded that encephalopathy can be caused by baclofen withdrawal. Although such “logical deduction” may be a reliable method when suppоrted by sufficient facts or data, the expert conceded in her deposition that “[n]one” of her patients “have suffered any type of permanent injury from an episode of [b]aclofen withdrawal . . . [or] overdose.” Thus, her own experiencе did not provide her with “exposure
¶17 Nor did the expert provide any supporting medical literature documenting examples of patients suffering permanent encephаlopathy caused, either directly or indirectly, by baclofen withdrawal when the baclofen level was reinstated, as it was in this case. To the contrary, the expert stated that she had “looked for” but was not “aware of any case similar to [the patient‘s] reported anyplace in the [medical] literature.” Further, the expert conceded that, according to medical literature, “patients who suffer [baclofen] withdrawal typically have symptoms resolved within 48 hours of having [b]aclofеn levels reinstituted.” In fact, “there is not a single reported case of baclofen withdrawal in which the patient remained stable throughout the episode and went on to suffer permanent neurological injury,” such as encephalopathy.
¶18 Beсause the expert‘s opinion regarding causation of the patient‘s injuries was not supported by any personal experience or medical literature, the district court did not exceed its discretion in excluding the expert‘s testimony for lack of sufficient facts and data.
CONCLUSION
¶19 We conclude the district court did not exceed its discretion when it excluded the expert‘s testimony for lack of sufficient facts or data. Accordingly, we affirm.
