What significant development in healthcare occurred during World War II?

During World War II, a notable development in healthcare was the creation of new clinics by Henry Kaiser for prepaid care. This initiative marked a significant shift in how healthcare services were delivered and funded. Kaiser, a prominent industrialist, partnered with labor unions to provide comprehensive health services to workers in the defense industries. These clinics were part of a broader approach to prevent health-related work disruptions and ensure a healthy workforce.

By establishing prepaid healthcare services, this model allowed workers to receive medical attention without the burden of immediate costs at the point of service. This innovation paved the way for modern managed care systems and health insurance models, influencing the way healthcare is structured and financed in the United States today. While the other options reference broader trends in healthcare, they do not capture the specific, impactful change introduced by Kaiser’s initiatives that ultimately shaped future healthcare policies and practices.
