Recently , his report contained information that he was nt supposed to see documents with another patient 's personal information including their condition , treatment plan and health care number . " I was quite surprised , " Grierson said . " I showed it to my wife who said , That s a disaster ! You should get in touch with somebody about that . " So Grierson contacted CBI Home Health and Alberta Health Services , which have since launched their own investigations . Human error likely to blame Grierson finds the privacy breach worrying . " If they can do this with my care records , can they do this with somebody else 's ? " Grierson asked . " What else are they going to lose ? " Rachel Hayward from the Privacy Commissioners Office ca nt comment on this specific case but says mistakes like this are usually caused by human error . " People moving papers quickly and papers getting attached from more than one file or more than one individual , " she said . AHS is also contacting the person whose records were sent to Grierson to see if that individual also received someone elses health information . ;
