In a new study, Niam Yaraghi and Ram Gopal use data on breach incidents occurring in the years before and after the rules change to analyze its effect. Their results, visualized below, show that implementation of the omnibus rules led to a significant reduction in the number of privacy breaches among business associates, preventing 165 breaches that could have affected nearly 17 million Americans.
Medical Data Breaches, By Year
Since 2010, 1,819 data breaches affecting 500 or more patients have occurred in the U.S. originating from both health-care providers and their third-party business associates. In 2013, new HIPAA regulations required business associates to put in place safeguards to protect patient information. The rules have prevented an estimated 165 breach incidents among business associates. OCR announced the HIPAA omnibus rules on January 25, 2013. These rules became effective March 26, 2013, with compliance required by September 23, 2013.
Individuals affected by medical data breaches
Implementation of the HIPAA omnibus rules coincided with a spike in the number of privacy breaches in the health care market. Based on this observation, one could argue that had the omnibus rules not been in place, we would have observed a similar spike in the number of privacy breaches among business associates. In other words, implementation of the rules has dampened the effects of an otherwise powerful driver of privacy breaches.
