Samaan v. St. Joseph Hospital
755 F. Supp. 2d 236
D. Me.2010Background
- January 14, 2006: Mr. Samaan suffered an ischemic stroke during a flight; he arrived at St. Joseph Hospital in Bangor, Maine by 12:40 p.m. and was not given t-PA.
- Plaintiff alleges Dr. Kaplan’s failure to administer t-PA within three hours caused severe deficits.
- Plaintiff designated Dr. Tikoo as an expert whose opinion is that timely t-PA would have likely benefited Samaan.
- Defendant moved to exclude Tikoo’s testimony as non-Daubert-compliant; the court held a Daubert hearing.
- Court recognized NINDS as the gold standard for t-PA efficacy and reviewed whether Tikoo’s reliance on odds ratios showed a more-likely-than-not benefit for Samaan.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of Tikoo’s testimony under Daubert | Tikoo’s method is scientifically sound and reliable | Tikoo’s methods and conclusions fail Daubert reliability | Tikoo testimony excluded |
| Maine causation standard applied | Loss-of-chance doctrine may apply in Maine | Maine uses the more-likely-than-not standard | More-likely-than-not standard governs; loss-of-chance not adopted here |
| Reliance on NINDS and related analyses | NINDS data show >50% chance of benefit | Absolute benefit not shown; odds ratio insufficient | Court found no preponderance of evidence that t-PA more likely than not benefited Samaan |
| Reliance on ECASS-III and other studies | Additional studies support benefit of later t-PA window | Not applicable to establish individual causation | ECASS-III and similar data do not establish more-likely-than-not causation for this case |
