St. Peter 's Health Partners , the Albany , New York region 's largest hospital system , is notifying 5,117 of its patients that some information about them was involved in a potential data breach after a manager 's cellphone was stolen . The incident affected patients at St. Peter 's Medical Associates P.C. , one of the system 's physician groups . The manager 's cellphone had access to corporate email systems , but St. Peter 's officials said they received no reports that patient information has been improperly used . The affected data included scheduling details , such as the patient name and date of birth , as well as the day , time and location of medical appointments , along with a general description of the reason for the appointment . The breach primarily involved data from August to November 2014 . The emails did not include other medical records and personal identity information , such as financial accounts and Social Security numbers . Two patients ' home addresses and phone numbers were included in the emails and they were notified previously . Hospital officials said they learned of the phone theft and potential breach on Nov. 24 . They reported it to law enforcement and took other cyber security steps , such as remotely wiping data from the device and disconnecting it from the hospital system 's corporate email system . The hospital system , which has about 12,500 employees total , and is the region 's largest private - sector employer , announced today it has sent notifications to all 5,117 patients affected by the breach . " While at this time we believe the risk is low that the data on these individuals was accessed , we are committed to doing all we can to protect each and every one of them , " Donald Martin , chief executive officer of SPHP Medical Associates , said . The stolen cellphone was password protected , but was not encrypted in accordance with St. Peter 's Health Partners customary security procedures , according to the hospital system . ;
