Employees and contractors at VA medical centers, clinics, pharmacies and benefit centers commit thousands of privacy violations each year and have racked up more than 10,000 such incidents since 2011, a ProPublica analysis of VA data shows. The breaches range from inadvertent mistakes, such as sending documents or prescriptions to the wrong people, to employees' intentional snooping and theft of data. Not all concern medical treatment; some involve data on benefits and compensation.
