Abstract In July 2023, the United States and the European Union introduced the Data Privacy Framework (DPF), introducing the third generation of cross-border data transfer agreements constituting adequacy with respect to personal data transfers under the General Data Protection Regulation (GDPR) between the European Union (EU) and the US. This framework may be used in cross-border healthcare and research relationships, which are highly desirable and increasingly essential to innovative health technology development and health services deployment. A reliable model meeting EU adequacy requirements could enhance the transfer of patient and research participant data. While the DPF might present a familiar terrain for US organizations, it also brings unique challenges. A notable concern is the ability of individual EU Member States to establish individual and additional requirements for health data that are more restrictive than GDPR requirements, which are not anticipated by the DPF. This article highlights the DPF’s potential impact on the healthcare and research sectors, finding that the DPF may not provide the degree of lawful health data transfer desirable for healthcare entities. We examine the DPF against a background of existing Health Insurance Portability and Accountability Act obligations and other GDPR transfer tools to offer alternatives that can improve the likelihood of reliable, lawful health data transfer between the US and EU.
