The costs of prescription drugs increased significantly in the USA over the past few years. 1 The prevalence of high-deductible health plans (HDHPs) also increased steadily over the last two decades. 2 Since HDHP enrollees may face the full cost of their initial purchases of prescription drugs, increases in the prices of prescription drugs are likely to have a significant impact on HDHP enrollees. Prior research examined total out-of-pocket health care expenditure burdens of HDHP enrollees. 3, 4 Little is known, however, about the burdens of out-of-pocket prescription drug expenditures in particular. This study examines financial burdens of out-of-pocket prescription drug expenditures across different levels of deductibles. The study focuses on low-income adults (family income less than 250% of Federal Poverty Level) with multiple, prevalent chronic conditions, who are more likely to be constrained by their resources and use more prescription drugs.

Data for this analysis come from 2012-2017 Medical Expenditure Panel Survey Household Component (MEPS-HC). The sample was restricted to adults ages 19 to 64 who were enrolled in employer-sponsored health insurance plans throughout the year. Data was pooled across multiple years given the small sample size of the subpopulation of lowincome adults with multiple chronic conditions. The following self-reported chronic conditions were identified: Diabetes, asthma, hypertension, arthritis, heart disease, cancer, chronic bronchitis, stroke, and emphysema. Following the literature, financial burden of prescription drugs was calculated as annual family out-of-pocket prescription drug spending divided by annual family disposable (after-tax) income, and 10-percent burden (out-of-pocket prescription drug spending exceeding 10 percent of disposable income) was used as a measure of high burden. 5 Health plans were classified into three categories-high-deductible (deductible levels exceeded the Internal Revenue Service threshold for high-deductible plans), low-deductible (deductibles were below the Internal Revenue Service threshold), and no-deductible health plans. Two-tailed t tests were used for making comparisons.

Among all adults (n = 39,421), the prevalence of 10-percent prescription drug burden was 1.2% or lower for any deductible group (Table 1) . Among low-income adults (n = 7,510), the prevalence of 10-percent burden for high-and low-deductible enrollees was 5.0% (p < .01) and 3.1% (p < .01), respectively, compared with 1.6% among no-deductible enrollees. Among low-income adults with two or more chronic conditions (n = 1,354), the high burden rate for the high-deductible group, at 14.3%, was higher than that for the no-deductible group at 5.5% (p < .05). Among low-income adults with multiple chronic conditions, high-deductible enrollees were more likely than the no-deductible enrollees to have a 10-percent burden from brand name drugs alone (11.5% versus 3.2%, p < .05), but the differences in the prevalence of 10-percent burden from generic drugs alone across deductible groups were not statistically significant (Table 2) .

Among low-income adults with employer-sponsored insurance who had multiple chronic conditions and were enrolled in high-deductible plans, about 14.3% had family out-ofpocket prescription drug expenditures exceeding 10 percent of family disposable income. While out-of-pocket costs for prescription drugs have decreased in recent years, 1 the results of this study suggest that for low-income adults with multiple chronic conditions who are enrolled in employer-sponsored high-deductible plans, out-of-pocket prescription drug costs may still result in significant financial hardships. As brand name drugs tend to be expensive, it is not surprising that the differences in financial burdens across deductible levels are coming primarily from out-of-pocket spending on brand name drugs. The coronavirus pandemic may further exacerbate the financial burdens of prescription drugs in numerous ways. For example, utilization of prescription drugs for mental health may increase 6 , which may affect the out-of-pocket costs for those in high-deductible health plans in particular. Also, loss Using the self-reported priority conditions in MEPS HC, the following diagnosed conditions were identified: Diabetes, asthma, hypertension, arthritis, heart disease, cancer, chronic bronchitis, stroke, and emphysema. Adults who reported having ever been diagnosed with coronary heart disease, angina, myocardial infarction, or any other kind of heart condition or heart disease were defined as having heart disease. Adults who reported having ever been diagnosed with asthma and who reported they still had asthma or had an asthma attack in the past 12 months were defined as having asthma. Adults who reported being diagnosed with high blood pressure on two or more occasions were defined as having hypertension † Base group *,**,***Statistically significantly different, based on two-sample t tests, from the no-deductible plan enrollees at the 5%, 1%, or 0.1%, respectively The sample comprised adults ages 19 to 64 who were enrolled in employer-sponsored health insurance plans and no other coverage throughout the year FPL, federal poverty level Using the self-reported priority conditions in MEPS HC, the following diagnosed conditions were identified: Diabetes, asthma, hypertension, arthritis, heart diseases, cancer, chronic bronchitis, stroke, and emphysema.

The impact might be worse for those with chronic conditions as they could be at higher risk of developing serious illness from coronavirus. The estimates from this study can be used as a baseline to compare with later estimates, once data on household prescription drugs use and income during the pandemic becomes available. The key takeaway point of this paper for general internists is that for patients with chronic conditions, who are more likely to use prescription drugs, outof-pocket costs of prescription drugs could be really burdensome if they are enrolled in high-deductible plans.
