50 biggest data breaches in healthcare

Data breaches in healthcare are becoming a more common occurrence, and each one reported appears more severe and far-reaching than the last.

 

Between 2010 and 2013, healthcare organizations reported 949 security breaches compromising approximately 29 million patient records, according to an International Business Times report. Additionally, data from the Kaiser Permanente Division of Research indicate the rate of breaches is on the rise. In 2010, 214 breaches were reported. That number climbed to 265 in 2013.

Healthcare organizations that experience a data breach affecting more than 500 individuals are required by the HITECH Act to report the breach to HHS' Office for Civil Rights. The HITECH Act required organizations to start reporting this information in 2009.

Here are the 50 hospital, health system or health plan data breaches that compromised the most number of individual patient records, as reported to the OCR.
