In June , a healthcare assistant from St Luke ’s Hospital was accompanying a patient on a transfer to another hospital when he left their chart on the roof of the car before setting off . He realised the mistake only when he arrived at their destination . The chart was later retrieved from a member of the public who had picked it up . The HSE responded by notifying the patient of the incident and reported the matter to the Data Commissioner . The staff member was reminded of their responsibilities under data - protection legislation . ;
