What Happened: The incident occurred when certain information about Castro Valley Health patients inadvertently was transferred during 2016-2017 to a third-party website called Docker Hub. Castro Valley Health first became aware of this incident on April 21, 2020, and promptly removed the information from the Docker Hub site. The transferred information was heavily coded and therefore not readable without significant decoding.

What Information Was Involved: The information that was transferred to the Docker Hub site included: patient names, an entry that said “Start of Care – Admission Visits,” the name of the nurse, physical therapist, or speech therapist who admitted the patient, the address at which the patient visit was to occur, the patient’s date of birth, medical record number, and the start of care date.

What Information Was NOT Involved: The information did not include Social Security numbers, driver license numbers, Tax ID numbers or bank account information. Importantly, the information also did not include clinical or diagnostic information, notes, plans or orders.

Castro Valley Health Response: Castro Valley Health began investigating the incident immediately after learning of it. We have no information at this time indicating anyone has used any of the patient information from the Docker Hub website, or that anyone other than the person who alerted the Department of Health and Human Services to the situation ever has viewed the information.

We are taking extra steps in addition to our existing policies to safeguard your information, including renewed training and employee orientation, conducting additional internal security audits and risk assessments and enhancing our policies and procedures.
