Merge unity pacs a medical image and information management system that is used for viewing, selection, processing, printing, telecommunications, and media interchange of medical images from a variety of diagnostic imaging systems.Merge healthcare was notified by a customer on (b)(6) 2017 that all users were not able to connect to the server.Testing and investigation by merge healthcare technical support determined that the site had been experiencing ongoing storage issues with their drives.In order to resolve this hardware storage issue, merge healhcare sent the customer six (6) new one terabyte (tb) drives.The new configuration would allow for distributing the pacs storage across multiple drives ensuring that free space and regular maintenance (defragging) would occur.However, during the on-site replacement installation, the array drive in the image server failed.The failed array was replaced.In the efforts of restoring the data, four exams were unable to be recovered.Therefore, each patient had to be re-scheduled for another mammogram exam at a later date.There is a potential for patients that require re-imaging due to data loss, to experience a delay in treatment and/or diagnosis that could lead to harm.At this time, there is no indication of an adverse event for the affected patients.(b)(4).
