An impaired physician is one unable to fulfill professional or personal res
ponsibilities because of psychiatric illness, alcoholism, or drug dependenc
y. Current estimates are that approximately 15% of physicians will be impai
red at some point in their careers. Although physicians may not have higher
rates of impairment compared with other professionals, factors in their ba
ckground, personality, and training may contribute and predispose them to d
rug abuse and mental illness, particularly depression. Many physicians poss
ess a strong drive for achievement, exceptional conscientiousness, and an a
bility to deny personal problems. These attributes are advantageous for "su
ccess" in medicine; ironically, however, they may also predispose to impair
ment. identifying impairment is often difficult because the manifestations
are varied and physicians will typically suppress and deny any suggestion o
f a problem. Identification is essential because patient well-being may be
at stake, and untreated impairment may result in loss of license, health pr
oblems, and even death. Fortunately, once identified and treated, physician
s often do better in recovery than others and typically can return to a pro
ductive career and a satisfying personal and family life.
