What is considered expert testimony in medical malpractice cases?

Expert testimony is admissible when it is "[r]elated to a subject that is sufficiently beyond common experience that the opinion of an expert would assist the trier of fact." (Evid. Code, 801, subd. (a).) "In addition to matters within their own personal knowledge, experts may relate information acquired through their training and experience, even though that information may have been derived from conversations with others, lectures, study of learned treatises, etc. This latitude is a matter of practicality. A physician is not required to personally replicate all medical experiments dating back to the time of Galen in order to relate generally accepted medical knowledge that will assist the jury in deciding the case at hand. An expert's testimony as to information generally accepted in the expert's area, or supported by his [or her] own experience, may usually be admitted to provide specialized context the jury will need to resolve an issue." (People v. Sanchez (2016) 63 Cal.4th 665, 675.)
