Illinois patients can now research their doctors using an online database the state launched Wednesday.

The idea is to take the guesswork out of choosing a doctor by allowing easier access to information about the state's 46,000 licensed physicians and surgeons.

The database can be accessed through the Department of Financial and Professional Regulation's website at idfpr.com under the "physician profile" link on the left side. There, patients can learn about a doctor's educational background and training, determine what type of insurance they accept and find out what languages are spoken in the office.

Also included is information about criminal convictions, disciplinary action against the doctor by regulators in Illinois and other states, and whether hospital privileges have been revoked.
