In total, there were 143 data breaches reported to the media or the Department of Health and Human Services’ Office for Civil Rights (OCR) in Q2, 2018 and the healthcare records of at least 3,143,642 patients were exposed, impermissibly disclosed, or stolen. Almost three times as many healthcare records were exposed or stolen in Q2, 2018 as Q1, 2018.
The figures come from the Q2 2018 Breach Barometer Report from Protenus. The data for the report came from OCR data breach reports, data collected and collated by Databreaches.net, and proprietary data collected through the Protenus compliance and analytics platform, which monitors the tens of trillions of EHR access attempts by its healthcare clients.
Q2 2018 Healthcare Data Breaches
|Month||Data Breaches||Records Exposed|
Q2, 2018 saw five of the top six breaches of 2018 reported. The largest breach reported – and largest breach of 2018 to date – was the 582,174-record breach at the California Department of Developmental Services – a burglary.
It is unclear if any healthcare records were stolen in the breach although data theft could not be ruled out. Many physical records were damaged by a fire started by the burglars which activated the sprinkler system which caused water damage. Electronic equipment was taken although it was encrypted.
The second largest data breach of 2018 was reported by MSK Group in May. The orthopedic group detected unauthorized access of parts of its network that contained the protected health information of 566,236 patients.
The third largest breach of 2018 involved the exposure and potential theft of 538,127 records from LifeBridge Health. Malware had been installed on a server on which billing information and medical records were stored.
The fifth and sixth largest breaches of the year to date were reported in June. Oklahoma State University Center for Health Sciences experienced a 279,865-record breach when its computer network was hacked and Med Associates, Inc., discovered a desktop computer had been hacked resulting in the exposure of 276,057 patients’ PHI.
The Threat from Within
Protenus has drawn attention to the threat from insider breaches and the importance of detecting privacy breaches promptly. When medical records are accessed by employees without authorization, there is a 30% chance of an employee violating patient privacy again within 3 months and a 66% chance they will do so again within 6 months. One of the main problems for hospitals is the time taken to investigate and respond to insider threats. On average, one investigator monitors the ePHI access attempts of 4,000 employees across an average of 2.5 hospitals – a significant burden.
Out of every 1,000 healthcare employees, Protenus determined than 9 will breach patient privacy, most commonly by snooping on the medical records of family members. In Q2, 2018 71.4% of snooping incidents were employees viewing family members’ medical records.
30.99% of breaches (44) reported to the Office for Civil Rights in Q2 were insider breaches, and out of the 27 incidents for which details have been disclosed, the records of 421,180 patients were known to have been compromised. There were 25 incidents involving insider error and 18 incidents involving insider wrongdoing.
Healthcare Hacking Incidents Increased in Q2 2018
The biggest cause of healthcare data breaches in Q2, 2018 was hacking/IT incidents which accounted for 36.6% of all reported breaches in the quarter. There were 52 hacking/IT incidents reported in Q2, compared to 30 in Q1 – a 73% increase. Those breaches resulted in the exposure/theft of at least 2,065,813 healthcare records.
Details were available for 44 breaches, ten of which were phishing-related breaches, 7 involved ransomware or malware, and one involved another form of extortion.
There were 23 reported cases of theft of physical or electronic records and a further 23 breaches that did not include enough information for them to be categorized. Overall, 84% of breaches involved electronic records and 16% involved paper records.
Healthcare providers were the worst hit with 76.37% of reported breaches, following by health plans on 10.91%, business associates on 5.45%, and other entities on 7.27%.
The average time to discover a breach was 204 days and the median time was 18 days. The detection times ranged from one day to 1,587 days. From the available data, the average time to disclose breaches to the Office for Civil Rights was 71 days and the median time was 59 days. The maximum time frame under HIPAA for disclosing breaches is 60 days. California was the worst hit state with 20 incidents followed by Texas on 13.
