636 F.3d 20
1st Cir.2011Background
- Plaintiffs appeal a grant of summary judgment in a Puerto Rico Article 1802 medical malpractice case.
- Rodríguez-Díaz had a March 2007 fine-needle biopsy diagnosing pleomorphic adenoma, a benign salivary gland tumor.
- HRPA pathologist Dr. Carlo amended the diagnosis to low-grade mucoepidermoid carcinoma after additional testing.
- Surgery in August 2007 removed the malignant tumor and pathology confirmed the revised diagnosis.
- Plaintiffs sued in 2008 in federal court based on diversity; district court granted summary judgment September 22, 2009, holding plaintiffs failed to prove the standard of care without expert testimony.
- Court reviews de novo under Puerto Rico fault-based standard and notes expert testimony is usually required to prove negligence.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether expert testimony is required to prove malpractice under Article 1802. | Rodríguez-Díaz argues the differential diagnosis issue shows negligence. | Rodríguez asserts standard-of-care expert testimony is necessary. | No; court holds expert testimony required and exceptions not shown. |
| Whether failure to perform a differential diagnosis constitutes negligence given evidence. | Failure to differential diagnosis could be negligent given revised malignant diagnosis. | Differential diagnosis not required to prove negligence; other factors support care adequacy. | Not proven; lack of expert testimony and lack of clear standard defeats prima facie case. |
