A patient at Crooked Oak Family Medicine has stolen a document listing personal information about 527 other patients , the practice 's owner , Lancaster General Medical Group , said Thursday . According to LGMG , the document , which was stolen Feb. 5 , does not show patients ' Social Security numbers , credit - card information or addresses . However , it does list patients ' names , genders , dates of birth and whether they had received certain cancer screenings . It also shows whether a pediatric well child - care visit had been conducted and whether patients had received the pneumococcal vaccination against pneumonia and bacterial meningitis . All patients named on the spreadsheet have been notified by letter of the theft . LGMG said there 's no evidence that the patient information on the document has been misused . Nonetheless , LGMG is offering 12 months of free identity - theft protection services to any patient on the document . The services include credit monitoring . The practice is at 1655 Crooked Oak Drive , off Eden Road . LGMG said the incident happened when an adult male patient at Crooked Oak became agitated and disruptive . To calm the patient , he was taken to the practice manager 's office . But the patient grabbed a stack of papers from the manager 's desk and ran out of the building , LGMG said . The patient returned briefly to the practice the next day , but without the document . Several attempts have been made to recover the document from the patient , but he has not complied , LGMG said . LGMG spokesman John Lines said LGMG did not immediately announce the theft because it 's still trying to retrieve the spreadsheet . Lines said he was prevented by patient confidentiality guidelines from releasing the name of the patient who LGMG says stole the document . The patient has not been charged by Manheim Township police . " No charges have been pursued at this time , " Lines said . " It remains an option under consideration . " Lines said LGMG continues to be hopeful that it can get the spreadsheet back from the patient . LGMG and Crooked Oak are reviewing its office policies and procedures to prevent a similar incident in the future . " We take this matter very seriously , " Lines said . " We 're sorry for the inconvenience it 's caused . " ;
