Brief Summary:

Asthma is one of the most common chronic diseases in the U.S. Despite guidelines, adherence to recommended controller medications is low. Cost is an important barrier to adherence. Employers are increasingly adopting high-deductible health plans (HDHPs) which require deductibles of > $1,000 per individual/$2,000 per family each year. In HDHPs with Health Savings Accounts (HSAs), most medications and non-preventive care must be paid out-of-pocket (OOP) until the deductible is reached. The lower premiums of HSA-HDHPs are appealing, but the high level of OOP costs can lead patients to forgo needed care. HSA-HDHPs can exempt preventive care from the deductible, and employers can add Preventive Drug Lists (PDLs) which exempt certain chronic medications from the deductible (including asthma medications), making them free. PDLs have the potential to improve controller medication use, which could prevent negative health outcomes and reduce cost-related trade-offs for families.

The goal of this research is to evaluate the impact of these two developments in the health insurance market -- HSA-HDHPs and PDLs -- on medication use and clinical outcomes for adults and children with asthma. To do this, tteh investigators will first conduct in-depth interviews with patients with asthma and parents of children with asthma who have HDHPs and traditional plans. Interviews will collect patient-reported data on how patients and their families navigate their insurance plan and make health care decisions when faced with OOP costs. Findings from the interviews will inform analyses of data from a large national health plan from 2004-2017. Investigators will select adults and children with asthma whose employer switched them from traditional plans to HSA-HDHPs with or without a PDL. Analyses will examine changes in asthma medication use, emergency department (ED) visits, hospitalizations, and OOP costs before and after changing plans compared to similar patients who did not switch to a HSA-HDHP. The study aims to: 1) understand health care decision making and experiences of families with asthma with HDHPs; 2) examine the impact of HSA-HDHPs with and without PDLs on use of asthma medications and asthma-related ED visits and hospitalizations; 3) examine the extent to which the response to HSA-HDHPs and PDLs is affected by the presence of other family members with asthma or other chronic conditions; 4) examine the impact of HSA-HDHPs with and without PDLs on OOP costs for families.

Primary Outcome Measures :
  1. Proportion of days covered [ Time Frame: baseline year to follow up year ]
    change in adherence to any asthma controller medications as measured by change in proportion of days covered per month

  2. Medication discontinuation rate [ Time Frame: baseline year to follow up year ]
    change in adherence to any asthma controller medication as measured by change in medication discontinuation rate

  3. Use of asthma rescue medications [ Time Frame: baseline year to follow up year ]
    change in standardized number of inhalers dispensed per month

  4. Asthma-related ED visits and hospitalizations [ Time Frame: baseline year to follow up year ]
    change in asthma-related ED visits or hospitalizations that have a primary ICD-10 diagnosis code for asthma

  5. Out-of-pocket costs [ Time Frame: baseline year to follow up year ]
    change in out-of-pocket costs for asthma medications and other health services, measured by summing deductible, co-pay, and coinsurance amounts into annual measures; also measured as annual family OOP costs as a percent of family income, with cutpoints of >5% and >10% to indicate financially burdensome OOP costs
