The Seattle Cancer Care Alliance began notifying nearly 1,000 patients Oct. 16 that their information may have been exposed due to an email error.
The group discovered Aug. 27 that an email invitation was sent to patients without using the blind carbon copy function. This caused patients' email addresses to be visible to all recipients. The email contained patients' email addresses and information to attend an educational event. No financial information, Social Security numbers or clinical information was in the email.
Since the incident, SCCA is evaluating its systems and processes.
"SCCA is committed to providing quality care while protecting our patients' personal information. SCCA has no evidence that this information was misused, and we sincerely regret any concern or inconvenience this mistake may have caused our patients," the group said in a statement.
