Malpractice claims dipped dramatically among Massachusetts physicians after they began using electronic medical records, according to new research, although it's not clear whether the record-keeping was connected to the decline in claims. Despite its limitations, however, the research provides more evidence that electronic health records "improve quality and safety and, as a result, prevent adverse events and reduce the risk of malpractice claims," said study co-author Dr. Steven Simon, an associate professor with Harvard Medical School and an internist with VA Boston Healthcare System.
