Tool may predict cancer patients’ risk of financial stress

A new questionnaire can measure a cancer patient’s risk for financial stress, according to a paper published in Cancer.

Researchers developed the 11-item questionnaire, called the COmprehensive Score for financial Toxicity (COST), through conversations with more than 150 cancer patients.

The team used the term “financial toxicity” to describe the expense, anxiety, and loss of confidence confronting patients who face big, unpredictable costs of cancer treatment.

And the researchers said financial toxicity can be considered another side effect of cancer care.

“Few physicians discuss this increasingly significant side effect with their patients,” said study author Jonas de Souza, MD, of the University of Chicago Medicine in Illinois.

“Physicians aren’t trained to do this. It makes them, as well as patients, feel uncomfortable. [However,] we believe that a thoughtful, concise tool that could help predict a patient’s risk for financial toxicity might open the lines of communication. This gives us a way to launch that discussion.”

Development of the COST questionnaire began with a literature review and a series of extensive interviews. Dr de Souza and his colleagues spoke with 20 patients and 6 cancer professionals, as well as nurses and social workers, and this produced a list of 147 questions.

The researchers pared the list down to 58 questions. Then, they asked 35 patients to help them decide which of the remaining questions were the most important. And the patients narrowed the list down to 30.

“In the end, 155 patients led us, with some judicious editing, to a set of 11 statements,” Dr de Souza said. “This was sufficiently brief to prevent annoying those responding to the questions but thorough enough to get us the information we need.”

All 11 entries are short and easy to understand, according to the researchers. For example, item 2 states, “My out-of-pocket medical expenses are more than I thought they would be.” And item 7 states, “I am able to meet my monthly expenses.”

For each question, patients choose from 5 potential responses: “not at all”, “a little bit,” “somewhat,” “quite a bit,” or “very much.”

Learning how a patient responds may help caregivers determine who is likely to need education, financial counseling, or referral to a support network. The quiz may also predict who is likely to have problems and require interventions.

All patients who helped develop the study had been in treatment for at least 2 months and had received bills. Excluding the top 10% and the bottom 10%, patients in the study earned between $37,000 and $111,000. The median annual income for these patients was about $63,000.

The researchers expected that financial toxicity would correlate with income.

“But, in our small sample, that did not hold up,” Dr de Souza said. “People with less education seemed to have more financial distress, but variations in income did not make much difference. We need bigger studies to confirm that, but at least we now have a tool we can use to study this.”

The researchers are now conducting a larger study to validate these findings and correlate the newly developed scale with quality of life and anxiety in cancer patients.

“We need to assess outcomes that are important for patients,” Dr de Souza said. “[T]his is another important piece of information in the shared-decision-making process.”
