High-deductible health plan can deter women from attending additional screening mammography

Researchers who surveyed women attending breast cancer screening appointments found that one in five is likely to skip additional testing after an abnormal finding on their mammogram if there is a deductible or co-payment, according to an editorial published in Radiology, a journal of the Radiological Society of North America (RSNA).

Health care costs and insurance premiums have increased in recent years. With the advent of the Affordable Care Act (ACA), high-deductible health plans (HDHPs) have grown in popularity, particularly among younger, healthy people.

It is believed that HDHPs lower overall health care costs by making individuals more cognizant of their medical expenses. The higher deductible also lowers monthly insurance premiums, making these plans an attractive option for healthy people who may typically need coverage only for preventative care or health emergencies.

But while HDHPs offer some advantages, the high out-of-pocket deductible cost-;a minimum of $1,500 for individuals and $3,000 for families-;may prevent people from seeking necessary care.

Currently, there is no out-of-pocket payment or co-payment for screening mammography since it's covered under the ACA. However, any follow-up diagnostic imaging for an abnormal finding seen on screening mammography may require the patient to pay a co-payment or deductible, depending on their healthcare plan."

Dr. Ngo and colleagues wanted to assess the impact that these payments had on a patient's willingness to return for important follow-up imaging.

The researchers surveyed 932 patients presenting for breast imaging at Boston Medical Center between September 2021 and February 2022. The survey was comprised of demographic questions on race, education level, annual household income and insurance payor, as well as scenarios about utilization of breast imaging. There was a variable response rate on questions.

When asked whether they would skip indicated imaging if they knew they had to pay a deductible, of 714 respondents, 151 (21.2%) said they would skip imaging, 424 (59.4%) said they would not skip imaging, and 139 (19.5%) were undecided.

"The patients who were more likely to say they would skip diagnostic imaging tended to be racial/ethnic minorities, have a lower educational level, have a lower-income household, are on Medicaid or have no insurance at all," Dr. Ngo said.

The groups with the highest percentage of responses indicating they would skip additional imaging were Hispanic (33.0%), high school educated or less (31.0%), household income less than $35,000 (27.0%) and Medicaid/uninsured (31.5%).

"Prior research has shown that these groups tend to already have lower adherence to preventative services, including breast cancer screening, and tend to have worse breast cancer outcomes," Dr. Ngo said. "Based on these results, these out-of-pocket payments may account for at least a part of the delay in seeking care. This, in turn, leads to delays in breast cancer diagnosis and treatment, increases overall breast cancer mortality and exacerbates existing gaps in breast cancer care in women who already have financial barriers in care."

The survey also asked whether respondents would forgo the initial screening mammography exam if they knew they would have to pay a deductible for follow-up tests. Of 707 respondents, 129 (18.3%) said they would skip the screening mammography exam, 465 (65.8%) would not skip mammography, and 113 (16.0%) were undecided.

Identifying socioeconomic barriers to health care is critical in addressing existing disparities and ensuring better outcomes for vulnerable patient populations. The researchers hope that these findings will be useful in efforts to remove financial barriers to care.

"We hope these results can be used to advocate for legislation to eliminate out-of-pocket expenditure for screening diagnostic imaging follow-up to alleviate the existing healthcare disparities," Dr. Ngo said.
