Harvard: In 2008 the FDA banned a class of asthma inhalers that contained
ozone-depleting propellants. These banned inhalers were available in
both generic and branded versions, and the ban left people with
asthma-only branded inhalers only one option: inhalers utilizing a
recently-developed propellant technology.
A new study has found that the out of pocket costs of the average
asthma patient with private insurance in the country nearly doubled
following the FDA ban. The research, led by Anupam Jena,
measures the financial and health impact of the ban, which critics said
would have a minimal environmental benefit. The findings were
published online today in JAMA Internal Medicine.
“The goal of reducing the use of ozone-depleting chemicals is
obviously an important one, but we wanted to see how patients with
asthma were affected by this policy,” Jena said.
More than 25 million people in the U.S. rely on inhalers for short-acting relief of asthma symptoms.
Policy Change Effects
Jena and colleagues at the Leonard D. Schaeffer Center for Health Policy and Economics at the University of Southern California and the Division of Health Policy and Management, at the University of Minnesota School of Public Health in Minneapolis, wanted to know what the financial and health impacts of the policy change were.
The researchers found that branded inhalers cost patients from $5 to
$75 more than generic inhalers, depending on insurance plan and type of
inhaler used.
Across more than 140,000 asthma patients in 77 different health
plans, the researchers found an average increase of $10 per inhaler
prescription, or nearly double what patients with asthma paid out of
pocket prior to the FDA ban.
While they saw a slight decline in overall inhaler use, they found no
increase in hospitalizations and no decline in the use of maintenance
drugs to control asthma.
An important limitation of the study is that it does not include
patients without insurance, who might face more serious challenges with
the new, more expensive inhalers, said study co-author Pinar
Karaca-Mandic, associate professor in the Division of Health Policy and
Management, at the University of Minnesota School of Public Health.
Ozone Depletion
The rule change was allowed under the U.S. Clean Air Act, which
prohibits the use of nonessential technology that uses ozone-depleting
chemicals.
Ozone depletion causes serious risks for humans, including an increased danger of skin cancer.
For years, the FDA allowed CFC-inhalers as medically necessary, but
announced plans to phase them out in 2008 when new inhalers using a
different propellant became available.
The ban has been controversial both because of concerns about
increased costs for essential medication and because of skepticism about
the relative value to the environment of banning CFC-propelled
inhalers.
While damage to the ozone layer has significant, dangerous
consequences, the share of emitted CFCs that come from inhalers was less
than one-thousandth of total emissions, according to a 2011 Mother Jones
article that cited estimates suggesting that the ban will likely have a
“minimal” effect. The article also noted that the new inhalers use a
propellant that is a known powerful greenhouse gas.
“Economics gives researchers and policymakers a set of tools that
allow us to bring evidence to bear on complex policy decisions,” Jena
said.
“In this case, patients with asthma have essentially subsidized
environmental efforts to improve the ozone, by paying higher prices for
their medications. To tackle tough problems like this we need to know
the costs and benefits of all the policies being considered. Our study
provides an important piece to that puzzle,” he said.
