Lack of understanding of the legal concept of vicarious liability may
underlie certain barriers to nurse-midwifery practice. Malpractice ins
urance surcharges, denial or restrictive limitation of clinical privil
eges, and physician ''supervision'' requirements may all be premised,
at least in part, upon an assumption that physicians who work with, an
d hospitals that grant clinical privileges to, nurse-midwives will aut
omatically be liable for any negligent actions or omissions of CNMs. T
his article examines the basis for such assumptions and, based upon re
search into the current case law on this subject, concludes that popul
ar assumptions regarding physician/CNM or hospital/CNM vicarious liabi
lity are unfounded. According to the author's research, no reported ca
ses exist to support that assumption. Vicarious liability arises from
the relationship between two parties and is imposed solely on the basi
s of the relationship. An employer is almost always vicariously liable
for the negligent actions or omissions of his employee. If a nurse-mi
dwife is the bona fide employee of a hospital or physician, the latter
will most likely be subject to vicarious liability. Absent of any emp
loyment relationship, however, such liability will not necessarily be
imposed. Rather, the result will vary depending upon the facts of each
case, and each professional's relative degree of fault would be deter
mined upon the basis of his or her own actions. Hospital liability for
nonemployee nurse-midwives who hold clinical privileges should be no
different from hospital liability for physician members of its medical
staff-that is, in most cases the hospital will not be vicariously lia
ble for the negligence of its nonemployee staff, but will be directly
liable for its own negligence if it failed to credential or monitor th
e performance of its staff members properly. A malpractice surcharge c
ase, and the insurance principles and data that may be derived from th
at case, are also discussed.
