The number of patients whose hospital records were improperly accessed by employees at the UCLA Hospital System has topped 1,000, said Kathleen Billingsley, director of the California Department of Public Health's Center for Healthcare Quality. The 1,041 breached patient records is up from 939 in the state's last report in August. The hospital said it has taken measures to ensure patient confidentiality, including increasing audits of employees who can access patient files and requiring employees to identify reasons for accessing clinical records.
