John Muir Health, a Walnut Creek, CA-based hospital system, said it has begun notifying 5,450 patients by mail of a "potential breach of their personal and health information." The move came after the theft two months ago of two laptop computers at the John Muir Physician Network Perinatal office in Walnut Creek, officials said. In addition to the Walnut Creek Police Department, the U.S. Department of Health and Human Services has been notified of the theft and possible privacy breach.
