CINCINNATI (AP) _ A man posing as a doctor performed gynecological exams, minor surgery and prescribed medicine at several hospitals for as long as 14 months before a suspicious patient called authorities, police said Thursday.

Thomas David West, 32, of Erlanger, Ky., was charged with practicing medicine without a license and other charges.

West performed gynecological examinations twice this spring in a University of Cincinnati Hospital emergency room, police Sgt. John Burke said.

He allegedly performed minor surgery on a man's leg lesions at Cincinnati's Good Samaritan Hospital and prescribed drugs over the telephone.

''We haven't been able to verify that he has any surgical training,'' Burke said.

West had surgery-room clothing and identification, Burke said. Police have not determined whether anyone paid West or whether he has a college degree, Burke said.

The hospitals were unaware of his alleged activities, Burke said. He allegedly arranged to meet prospective ''patients'' at the hospitals.

Authorities began investigating West when a person he treated became suspicious and called police.
