Modern Healthcare Illustration / Getty Images Scripps Health has restored access to patient medical histories, and expects to have its electronic health records later back this week, almost a month after it was first hit by a ransomware attack. In a letter to patients Monday, CEO and President Chris Van Gorder acknowledged patient frustrations that the San Diego-based health system wasn't communicating enough. But he said they haven't been as transparent because sharing more details has put Scripps at increased risk of more attacks. "This is not hypothetical; other attacks are already using what is being reported in the media to send scam communications to our organization," Van Gorder wrote, also confirming that the cyberattack was in fact via ransomware.
