Over decades, the shrinking pool of CHs – who are compensated far less than hematologist-oncologists – has put patients at risk without access to adequate and timely care. To alleviate this crisis, individual doctors and national organizations are taking action and making more resources available to CHs and their patients.
`Vicious cycle’
The root cause of the CH shortage can be traced to a dramatic reduction in the number of physicians trained in this field, as Leonard Valentino, MD, President of the National Bleeding Disorders Foundation in New York, explained in an interview.
“There is a vicious cycle where there’s not enough classical hematologists to be program directors, and therefore trainees are often steered to fellowships in oncology,” said Dr. Valentino.
According to data published in JAMA, in 1995 there were 74 classical hematology programs in the United States; by 2018, there were only 2, During this same time period, the number of combined hematology/oncology training programs (HOPs) nearly doubled, from 75 to 146. However, it is estimated that less than 5% of graduates of adult HOPs pursued a career in classical hematology, as reported in Blood Advances. This low percentage can be attributed, at least in part, to the emphasis that most HOPs place on oncology.
Dr. Valentino noted that financial pressures are also diverting medical students from becoming CHs, adding that a hematologist-oncologist can make three times the annual salary of a CH.
Furthermore, when CHs treat bleeding and clotting disorders, they often need to meet with a patient for a 60- to 90-minute initial consultation, then they go on to provide a lifetime of labor-intensive care.
“This work is neither verticalized [that is, supported by radiologists, surgeons, and a cadre of nurses], nor is it billable per hour on a scale comparable to what oncologists can charge,” Dr. Valentino explained.
The survey published in Blood Advances illustrates the consequences of such a disparity in income potential: 34% of hematology/oncology fellows surveyed were likely to enter solid tumor oncology, while 20% and 4.6% would proceed to malignant hematology and CH, respectively.
Toll on patients
Primary care doctors treat some common blood disorders, but they almost always refer more difficult or complicated cases to a shrinking population of CHs.
“For many Americans, it is getting more difficult to find providers who subspecialize in hemostasis and thrombosis disorders. Patients can expect prolonged waiting times to get evaluated after a referral” said Mukul Singal, MD, of the Indiana Hemophilia and Thrombosis Center in Indianapolis.
Dr. Singal said the shortage is so acute that “at many institutions, malignant hematologists or oncologists are having to staff in-patient hematology consult services and see outpatient classical hematology patients. General hematologist/oncologists or medical oncologists are often not as comfortable or experienced with dealing with some of the complex CH conditions.”
