The role of hematologists in a changing United States health care system.

Major and ongoing changes in health care financing and delivery in the United States have altered opportunities and incentives for new physicians to specialize in nonmalignant hematology. At the same time, effective clinical tools and strategies continue to rapidly emerge. Consequently, there is an imperative to foster workforce innovation to ensure sustainable professional roles for hematologists, reliable patient access to optimal hematology expertise, and optimal patient outcomes. The American Society of Hematology is building a collection of case studies to guide the creation of institutionally supported systems-based clinical hematologist positions that predominantly focus on nonmalignant hematology. These roles offer a mix of guidance regarding patient management and the appropriate use and stewardship of clinical resources, as well as development of new testing procedures and protocols.
