As of this writing, there are 294 incidents under investigation (published submissions) by the U.S. Department of Health and Human Services (HHS) for 2017, impacting well over 4.72 million individual patient records.

In this report, Dr. Rebecca Wynn, Chief Information Security Officer (CISO) of Matrix Medical Network, outlines the current outstanding breaches from 2017 that remain under investigation, and how guidelines within HIPAA lay a framework that can help thwart these incidents.

Here’s an overview of the submitted/reported healthcare industry breaches and their impact on records from a bird’s eye view:

So what is the definition of a healthcare breach, according to HIPAA?

A breach is, generally, an impermissible use or disclosure under the Privacy Rule that compromises the security or privacy of the protected health information. An impermissible use or disclosure of protected health information is presumed to be a breach unless the covered entity or business associate, as applicable, demonstrates that there is a low probability that the protected health information has been compromised based on a risk assessment of at least the following factors:

  1. The nature and extent of the protected health information involved, including the types of identifiers and the likelihood of re-identification
  2. The unauthorized person who used the protected health information or to whom the disclosure was made
  3. Whether the protected health information was actually acquired or viewed
  4. The extent to which the risk to the protected health information has been mitigated

Covered entities and business associates, where applicable, have discretion to provide the required breach notifications following an impermissible use or disclosure without performing a risk assessment to determine the probability that the protected health information has been compromised.

There are three exceptions to the definition of “breach.” The first exception applies to the unintentional acquisition, access, or use of protected health information by a workforce member or person acting under the authority of a covered entity or business associate, if such acquisition, access, or use was made in good faith and within the scope of authority. The second exception applies to the inadvertent disclosure of protected health information by a person authorized to access protected health information at a covered entity or business associate to another person authorized to access protected health information at the covered entity or business associate, or organized health care arrangement in which the covered entity participates. In both cases, the information cannot be further used or disclosed in a manner not permitted by the Privacy Rule. The final exception applies if the covered entity or business associate has a good faith belief that the unauthorized person to whom the impermissible disclosure was made would not have been able to retain the information.

How to minimize the impact of a breach?

  • Ensure antivirus/antimalware is installed and up to date across all endpoints within the business
  • Backup the data and store off your network (as frequently as you can afford)
  • Use Group Policy Objects (GPO) restrictions
  • Patch your systems (keep them as current as you can)
  • Restrict administrative rights on endpoints
  • Remember that reducing privileges will reduce the attack surface. Use the local user account as your primary account
  • Use a Secure Internet Gateway on and off the company network
  • Block users from installing anything. No rights to install. Go through a helpdesk system (with change control) and have a system administrator only install software that is on the approval list
  • Use Data Loss Protection and actively monitor
  • Invest in your Information Security program. Tools are great but it takes a team to properly manage and monitor
  • Establish security awareness campaigns that stress the avoidance of clicking on links and attachments in email

The HIPAA breach notification rule requires HIPAA covered entities and their business associates to provide notification following a breach of unsecured protected health information. Similar breach notification provisions implemented and enforced by the Federal Trade Commission (FTC), apply to vendors of personal health records and their third party service providers, pursuant to section 13407 of the HITECH Act.
