KFFs
KFFs is an acronym that can refer to several organizations or concepts, and there is no single, universally accepted meaning. The most widely recognized use is for the Kaiser Family Foundation, a United States nonprofit organization focused on health policy, health reform, and public health information. In standard usage, the organization is abbreviated as KFF rather than KFFs, and the plural form is uncommon unless the text explicitly discusses multiple separate entities that share the same initialism.
Beyond the Kaiser Family Foundation, KFFs may appear as an acronym for other foundations, funds, or federations
In formal writing, define the term on first reference and prefer the singular KFF for the Kaiser
