It's not very security-conscious of them to continue using IE11. These healthcare companies are being incredibly irresponsible by continuing to use an insecure and outdated browser; even going against Microsoft's own recommendation in doing so, as I understand it. By supporting IE11 your company is helping to enable the healthcare industry to continue using insecure software. A well-run IT department should be able to provide its users with a modern and secure browser. Why does your definition of a well-run IT department include the requirement that software installations should be restricted, but not a requirement to avoid using insecure and outdated software? I believe one can make a compelling case that the continued use of IE11 within the healthcare industry is unethical, as it provides a known attack vector by which people's data can potentially be stolen. Stop giving them a pass on this.
