BOULDER, Colo. (AP) -- A computer outage is preventing Boulder Community Hospital from accessing patient records, making it difficult for people to schedule surgeries and get test results for the past week. The outage affects the hospital, its Foothills campus, eight laboratories and six imaging centers. Meditech, the computer system used by the hospital to manage patient records, went down in the middle of last week. It could take the hospital until Friday to get the system back up. Hospital spokesman Rich Sheehan said computer experts are investigating what caused the outage, but the experts believe patient records are still protected and hospital officials don't believe they've been hacked.
