Factitious disorder is an uncommon, but probably underdiagnosed, condition associated with considerable morbidity, mortality, and health care expenditure. This diagnosis was made in 10 (0.8%) of 1,288 patients consecutively referred to the psychiatric consultation-liaison service of a tertiary-care general hospital. Seven of 10 identified cases were female. Associated psychiatric disturbances included substance use, psychogenic pain disorder, malingering, dysthymic disorder, and borderline personality disorder. Only two cases accepted ongoing psychotherapy. One death due to factitious behavior occurred during the brief period of follow-up. Greater awareness of this condition among primary caregivers is necessary in order to improve case identification and to reduce associated morbidity.
