A Kaysville physician convicted in February of negligent homicide in the death of a premature infant will not be allowed to practice obstetrics or treat children less than 2 months old, a state licensing board ruled Wednesday.

The physicians licensing board of the Utah Division of Occupational and Professional Licensing issued a ruling barring Dr. David Warden from practicing obstetrics and putting him on probation for five years.It also recommended he take a 30-day leave of absence from his medical practice. Warden will be allowed to resume neo-natal care and obstetrics after completing a board-approved educational program.

The board also ordered several additional conditions on Warden's probationary status, including informing patients he does not carry medical malpractice insurance, obtaining additional education, arranging for adequate patient care during absences, and meeting with the licensing board annually.

Warden and about 50 of his supporters appeared before the review board at a hearing in Salt Lake City in May. A complaint was filed with the board almost two years ago by another physician over Warden's treatment of a premature boy born at home to a Kaysville couple in November 1986.

The death of the infant, Jareth Young, also led to an investigation and eventual prosecution of Warden by the Davis County attorney's office.

Warden was convicted of negligent homicide, a Class A misdemeanor, by a six-member jury in February in 4th Circuit Court. The case is under appeal by Warden's attorney, Darwin Hansen.

The infant, according to testimony, was born two to three weeks early and suffered from a breathing disorder common among premature babies. The prosecution argued Warden, who delivered the baby at home, was aware of the problem and failed to have the baby hospitalized.

The infant died about 12 hours after his birth.
