UNIVERSAL HOSPITAL IS NOT LIABLE FOR THE CONDUCT OF SUBSEQUENT TORTFEASORS AND, THEREFORE, PLAINTIFFS’ DOUBLY-IMPUTED LIABILITY THEORY LACKS MERIT
As stated above, plaintiff’s contend that not only is Dr. Brown’s conduct imputed to Universal Hospital but the conduct of all subsequent tortfeasors should be imputed as well. Their contentions are incorrect.
The seminal case for subsequent medical treatment liability is Ash v. Mortensen (1944) 24 Cal.2d 654. The California Supreme Court in Ash held that the tortfeasor responsible for the original injury to plaintiff remained jointly and severally liable for injuries occurring during subsequent medical treatment for those injuries. This determination was based on a proximate cause analysis whereby the aggravated injury resulting from subsequent negligent medical treatment was considered foreseeable and a “normal part of the aftermath” of the original injury. (Id. at p. 657; Maxwell v. Powers (1994) 22 Cal.App.4th 1596, 1606.) As a consequence, the original tortfeasor becomes jointly and severally liable to plaintiff for those additional, subsequent injuries. (Blecker v. Wolbart (1985) 167 Cal.App.3d 1195, 1201-1203.)
In that regard, CACI Instruction No. 3929 provides:
If you decide that [defendant] is legally responsible for [plaintiff]’s harm, [he/she/it] is also responsible for any additional harm resulting from the acts of others in providing aid that [plaintiff]’s injury reasonably required, even if those acts were negligently performed. (Emphasis added.)
