HDHPs Deter Women From Additional Testing After Abnormal Mammogram, Study Says


The groups who told researchers they would be more likely to skip additional testing had lower levels of income or education and were more likely to be on Medicaid or be uninsured, among other factors.

One in 5 women is likely to skip additional testing after an abnormal finding on a screening mammogram if there is a deductible, according to researchers who looked at the impact of high-deductible health plans (HDHPs).

For the study, 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, out 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 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%).

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.

A higher deductible lowers monthly insurance premiums, making these plans appealing for individuals in good health who may typically need coverage only for preventative care or health emergencies. However, higher out-of-pocket deductible costs may deter some people from seeking necessary care.

The findings about HDHPs, ushered in after the passage of the Affordable Care Act (ACA), were presented at the annual meeting of the Radiological Society of North America (RSNA).

“The ACA removed out-of-pocket costs for screening mammograms under most health plans to encourage women to partake in this important preventative health care measure,” said the study’s lead author, Michael Ngo, MD, radiology resident at Boston Medical Center and Boston University Chobanian & Avedisian School of Medicine, in a statement. “However, the screening mammogram is only the first step in detecting breast cancer. If the radiologist detects an abnormal finding on the screening image, then additional images and a biopsy are needed to determine if the patient has cancer. The ACA does not mandate insurance to cover the costs of these additional services.”

Ngo and colleagues set out to determine the relationship between HDHPs and patient’s willingness to undergo indicated breast imaging.

“Prior studies have shown that out-of-pocket costs deter patients from attending screening mammography,” Ngo said. “Other studies found that screening rates go down when there is an out-of-pocket cost for follow-up imaging after an abnormal finding on screening mammography. However, there is a lack of research into patient adherence to the recommended follow-up imaging when there is a deductible.”

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.

“Our study demonstrates that out-of-pocket payments will discourage people, especially those belonging in the most vulnerable populations, from completing the last steps in the breast cancer screening process,” Ngo said. “These results could be used to advocate for legislation that will cover these important follow-up tests and prevent further exacerbation of existing health inequities.”
