West Penn Hospital has filed a complaint with the Pennsylvania attorney general in which it accuses Children's Hospital of Pittsburgh of violating an agreement to care for all children in the region. Children's Hospital recently decided to stop sending its doctors to West Penn Hospital to perform minor surgeries on infants. Instead, infants needing such care, about 25 a year, will be transported to Children's Hospital. A spokesman for Attorney General Tom Corbett said the office is reviewing the complaint, but he did not offer a timetable for completion of the review. Children's Hospital defended its decision, saying all children continue to have access to the hospital regardless of their ability to pay.
