Healthcare Insights
Most common types of healthcare data breaches
Protecting patient data is paramount in the healthcare industry. However, data breaches remain a serious concern, threatening patient privacy and disrupting healthcare operations.
The Definitive Healthcare HospitalView product tracks IT hacks and data breaches, along with data on technology installations for network and security systems, connected medical devices, and more. This data empowers users to understand potential vulnerabilities or needs when engaging with key hospital technology decision-makers.
The Department of Health and Human Services (HHS) also tracks healthcare data breaches through the Office for Civil Rights Breach Portal, as required by the HIPAA Breach Notification Rule. The tool provides valuable insights into the nature and scope of data breaches of unsecured protected health information (PHI) at healthcare provider organizations, healthcare insurance plans, and their business associates.
This Healthcare Insight reviews 2023 healthcare data breaches by their causes, sources of attack, and the number of health records affected.

What types of organizations are targets for healthcare data breaches?
HHS tracks data breaches at four types of organizations: healthcare providers, health plans, business associates, and healthcare clearinghouses.
Healthcare providers consistently report the highest number of reported breaches, potentially due to the thousands of hospitals and outpatient facilities across the country (compared to less than 1,000 health insurance carriers) and their levels of adoption of healthcare data security systems.
In 2023, 62.2% of healthcare data breaches took place at healthcare provider organizations. Business associates experienced 23.4% of the healthcare data breaches in 2023, and 13.9% were at health plans.
