Study: Costs may keep low-income patients from clinical trials

Cancer patients with lower incomes are a third less likely to be part of clinical trials that could help treat their disease than those whose annual income is at least $50,000, according to a new study.

Clinical trials, which test new treatments or prevention methods to determine whether they are safe and effective, are an essential component of medical research. Yet only a small percentage of eligible patients participate in them.

One of the main reasons fail is because they don't get enough people to enroll. If the number of patients who participate could be doubled or quadrupled, many more trials could be completed, says Joseph Unger, biostatistician and health services researcher in at the Fred Hutchinson Cancer Research Center in Seattle.

Unger and colleagues examined the association between income and clinical trial participation in 1,262 patients at eight cancer clinics during the six months following their initial diagnosis or recurrence of breast, colorectal or lung cancer. Their research letter, which was published in JAMA Oncology this month, found that 17 percent of those whose annual household incomes were $50,000 or higher participated in clinical trials, compared with 12 percent of those with incomes below that threshold.

The clinical trial will often cover the of the research treatment or procedure. But generally there are other costs involved, too. Even though most health plans and Medicare are required to pay for routine costs that could arise such as drugs, procedures and services that insurance would normally cover, patients may still be on the hook for copayments or coinsurance for those drugs and services, as well as travel and lost wages, among other things.

"Those marginal costs could still be a barrier" for lower income patients, Unger says.

Unger suggests that patients could be reimbursed for the extra costs of clinical trial participation, as long as care is taken to ensure financial inducements don't have the effect of strong-arming patients into trials. Some trials currently offer financial incentives, but the practice is haphazard, Unger says.

As for patients with , "If trials provide the newest treatments, there shouldn't be anything getting in the way of getting access to those treatments," says Unger.
