A review of data collected on 117,000 claims and lawsuits by the Physician Insurers Association of American (PIAA) reveals that medication errors are the second most frequent reason for claims against physicians and result, cumulatively, in the second highest indemnity paid, following faulty diagnosis and evaluation. According to a National Center for Health Statistics report in 1992, medications are ordered or provided at more than 19 million patient visits a year to an ophthalmologist’s office. With such a large volume of prescribing activity, it is not surprising that claims related to drug prescribing constitute a significant proportion of all claims for malpractice damages in ophthalmology.
