Directions for Use
In medical malpractice or professional negligence cases, the word “medical” or
“professional” should be added before the word “negligence” in the first paragraph
of CACI No. 400. From a theoretical standpoint, medical negligence is still
considered negligence. (See Flowers v. Torrance Memorial Hospital Medical
Center (1994) 8 Cal.4th 992, 997–998 [35 Cal.Rptr.2d 685, 884 P.2d 142].)
Also give the appropriate standard-of-care instruction for the defendant’s category
of medical professional. (See CACI No. 501, Standard of Care for Health Care
Professionals, CACI No. 502, Standard of Care for Medical Specialists, CACI No.
504, Standard of Care for Nurses, CACI No. 514, Duty of Hospital.)
It is not necessary to instruct that causation must be proven within a reasonable
medical probability based upon competent expert testimony. The reference to
“medical probability” in medical malpractice cases is no more than a recognition
that the case involves the use of medical evidence. (Uriell v. Regents of University
of California (2015) 234 Cal.App.4th 735, 746 [184 Cal.Rptr.3d 79].)
Sources and Authority
• “Professional Negligence” of Health Care Provider Defined. Code of Civil
Procedure section 340.5, Civil Code sections 3333.1 and 3333.2.
• “The elements of a cause of action for medical malpractice are: (1) a duty to
use such skill, prudence, and diligence as other members of the profession
commonly possess and exercise; (2) a breach of the duty; (3) a proximate
causal connection between the negligent conduct and the injury; and (4)
resulting loss or damage.” (Lattimore v. Dickey (2015) 239 Cal.App.4th 959,
968 [191 Cal.Rptr.3d 766].)
• “The court’s use of standard jury instructions for the essential elements of
negligence, including causation, was appropriate because medical negligence is
fundamentally negligence.” (Uriell, supra, 234 Cal.App.4th at p. 744 [citing
Directions for Use to this instruction].)
• “Section 340.5 defines ‘professional negligence’ as ‘a negligent act or omission
by a health care provider in the rendering of professional services, which act or
omission is the proximate cause of a personal injury or wrongful death,
provided that such services are within the scope of services for which the
provider is licensed and which are not within any restriction imposed by the
licensing agency or licensed hospital.’ The term ‘professional negligence’
encompasses actions in which ‘the injury for which damages are sought is
directly related to the professional services provided by the health care
provider’ or directly related to ‘a matter that is an ordinary and usual part of
medical professional services.’ ‘[C]ourts have broadly construed “professional
negligence” to mean negligence occurring during the rendering of services for
which the health care provider is licensed.’ ” (Arroyo v. Plosay (2014) 225
Cal.App.4th 279, 297 [170 Cal.Rptr.3d 125], original italics, internal citations
• “With respect to professionals, their specialized education and training do not
serve to impose an increased duty of care but rather are considered additional
‘circumstances’ relevant to an overall assessment of what constitutes ‘ordinary
prudence’ in a particular situation.” (Flowers,supra, 8 Cal.4th at pp. 997–998.)
• “Since the standard of care remains constant in terms of ‘ordinary prudence,’ it
is clear that denominating a cause of action as one for ‘professional negligence’
does not transmute its underlying character. For substantive purposes, it merely
serves to establish the basis by which ‘ordinary prudence’ will be calculated and
the defendant’s conduct evaluated.” (Flowers, supra, 8 Cal.4th at p. 998.)
• “The Medical Injury Compensation Reform Act (MICRA) contains numerous
provisions effecting substantial changes in negligence actions against health care
providers, including a limitation on noneconomic damages, elimination of the
collateral source rule as well as preclusion of subrogation in most instances, and
authorization for periodic payments of future damages in excess of $ 50,000.
While in each instance the statutory scheme has altered a significant aspect of
claims for medical malpractice, such as the measure of the defendant’s liability
for damages or the admissibility of evidence, the fundamental substance of such
actions on the issues of duty, standard of care, breach, and causation remains
unaffected.” (Flowers,supra, 8 Cal.4th at p. 999.)
• “[I]n a personal injury action causation must be proven within a reasonable
medical probability based upon competent expert testimony. Mere possibility
alone is insufficient to establish a prima facie case.” (Lattimore, supra, 239
Cal.App.4th at p. 970.)
• “That there is a distinction between a reasonable medical ‘probability’ and a
medical ‘possibility’ needs little discussion. There can be many possible
‘causes,’ indeed, an infinite number of circumstances which can produce an
injury or disease. A possible cause only becomes ‘probable’ when, in the
absence of other reasonable causal explanations, it becomes more likely than not
that the injury was a result of its action. This is the outer limit of inference
upon which an issue may be submitted to the jury.” (Jennings v. Palomar
Pomerado Health Systems, Inc. (2003) 114 Cal.App.4th 1108, 1118 [8
Cal.Rptr.3d 363], original italics, internal citations omitted.)
• “The rationale advanced by the hospital is that . . . if the need for restraint is
‘obvious to all,’ the failure to restrain is ordinary negligence. . . . [T]his
standard is incompatible with the subsequently enacted statutory definition of
professional negligence, which focuses on whether the negligence occurs in the
rendering of professional services, rather than whether a high or low level of
skill is required. [Citation.]” (Bellamy v. Appellate Dep’t of the Superior Court
(1996) 50 Cal.App.4th 797, 806–807 [57 Cal.Rptr.2d 894].)
• “[E]ven in the absence of a physician-patient relationship, a physician has
liability to an examinee for negligence or professional malpractice for injuries
incurred during the examination itself.” (Mero v. Sadoff (1995) 31 Cal.App.4th
1466, 1478 [37 Cal.Rptr.2d 769].)
