OREANDA-NEWS Many people with cancer end up having far more out-of-pocket health care expenses that they expected—despite having health coverage.

New data show that costs such as copays and deductibles can lead to financial distress among insured patients of all income levels and with all stages of cancer.

Cancer patients can be burdened by “financial toxicity” that can erode their mental and physical state, especially if they stop pursuing treatment because they feel they can’t afford it, says Yousuf Zafar, a medical oncologist at Duke University and senior author of the paper in JAMA Oncology.

“This study adds to the growing evidence that we need to intervene,” Zafar says. “We know there are a lot of barriers that prevent patients from talking about cost with their providers. We need to create tools for patients at risk of financial toxicity and connect them with resources in a timely fashion so they can afford their care.”

For the study, researchers interviewed 300 insured cancer patients. Sixteen percent of those interviewed reported high or overwhelming financial distress.

Those who were most distressed were spending about a third of their total household income on health care-related costs, not including insurance premiums. For more than 60 percent of this group, private insurance was the primary source of their health care.

By comparison, patients with little or average financial stress were spending about 10 percent of their household income on health care costs. More than half of patients with low financial stress had private insurance, and 39 percent had government-subsidized insurance.

“Overall, the patients in the study were paying an average of 11 percent on out-of-pocket costs for their cancer treatment,” says lead author Fumiko Chino, a resident in radiation oncology at Duke Health.

“Those who spend more than 10 percent of their income on health care costs are considered underinsured. Learning about the cost-sharing burden on some insured patients is important right now, given the uncertainty in health insurance.”

Having higher-than-expected out-of-pocket costs is associated with high levels of financial stress and a decreased willingness to pay for cancer care, the researchers found.
