At the age of 3, Hua, the only son in a family living in a small city along the Yangtze River in China, developed a fever. A dosage of cheap ototoxic antibiotic took away his hearing.
The doctor told Hua’s family that the only way he could hear again was to get a miracle device called a “cochlear implant.” His family quickly discovered that this “miracle device” came with a hefty price of US$30,000, which was 10 times his parents’ combined annual income. But with their son’s future at stake, Hua’s parents pooled their life’s savings and borrowed from grandparents, friends, and employers to get him this miracle device.
Today, at 10 years old, except for having an “atonal” accent, Hua is doing well as a fourth grader in a mainstream school. Hua often asks “why other families have a big TV and we don’t,” since he is too young to fully appreciate the fact that his family still owes half of the money for his implant.
A Miracle that Few Can Hope For
Consider Hua a lucky one because 99% of the deaf people in the world like Hua have no hope of getting a cochlear implant.
According to a 2005 report by the World Health Organization, 278
million people in the world have moderate to profound hearing loss in
both ears; 80% of them live in low-income countries. An estimated 5% of
the hearing-impaired population, or 14 million people, are potential
implant users. Yet, while the technology has been on the market since
the 1980s, only slightly more than 100,000 deaf people worldwide have
received a cochlear implant. That represents a pathetic 0.7% market
penetration rate.
Given the obvious need and proven benefit of cochlear implants,
price appears to be the main barrier preventing more widespread use of
this technology. With an average annual household income in developing
countries of less than $1000, most deaf people simply cannot afford a
cochlear implant. Moreover, medical insurance in these countries is
scarce and, even when available, it does not typically cover
interventions as expensive as cochlear implantation.
In developed countries with national health programs, such as
Canada, the United Kingdom, and most of Western Europe, the total
budget for implants is fixed. For example, a 1995 UK study reported
that the implant budget was £12 million, which, at an average cost of
£40,000 per device, could cover only 300 people. Yet, there are 650,000
people in the UK with severe or profound hearing loss.
In the United States, the device and surgery together cost from
$50,000 to $100,000. However, Medicare covers only $20,000 for both
device and surgery, making implants inaccessible to millions who don’t
have a first-rate health insurance plan. Clearly there is an urgent
need to lower the price of cochlear implantation without compromising
its performance.
What are the solutions to this grand challenge?
Tackling the Price Problem
One solution is exemplified by Yungching Wang, the founder and
chairman of Taiwan’s Formosa Plastics Corporation. Mr. Wang has begun a
donation of 15,000 devices from Cochlear Corporation for deaf children
in China and Cochlear is establishing clinics in that country. This
type of philanthropic work is certainly welcome as it increases
awareness and builds infrastructure. However, it represents only a
short-term solution, considering that 30,000 to 50,000 babies are born
deaf every year in China alone.
A more lasting solution would be a differential pricing system.
Cochlear Corporation has introduced a body-worn device in China that
costs about half as much as the full-fledged behind-the-ear device.
Med-El has also significantly lowered the price of its implants in
China. However, a more widely spaced differential pricing system needs
to be developed, in which the lowest price roughly matches the annual
household income in the targeted country.
Another possibility rests on the hope that present and future
cochlear implant manufacturers will broaden their services, thus
increasing their volume of business. Companies may also be able to
reduce their prices by adopting common technologies used in the hearing
aid, medical device, and telecom industries. For example, instead of
using custom chips for cochlear implants, manufacturers may be able to
use the same chips that are used in hearing aids or cell phones. A
common chip that costs only $10 might substitute for a custom chip
costing $1000.
Finally, the implant business needs competition, particularly from
local companies in emerging markets. At one time in the 1990s, there
were eight cochlear implant manufacturers. Today, only three are left,
and one, Cochlear Corporation, controls 70%-80% of the world market.
However, Korea and China have developed a prototype cochlear
implant, while India, with the strong personal support of its
president, A.P.J. Abdul Khalam, is developing one. Although the
shortage of relevant technology and know-how still presents a
significant hurdle for these endeavors, competition represents the best
chance for a long-term solution to meet this challenge.
What Can We Do?
What does all this mean to us in the hearing healthcare field?
Certainly the number of cochlear implant users will continue to grow.
Increased use of this technology will have a direct impact on
audiologists, hearing instrument specialists, and speech pathologists.
For one thing, it will increase demand for professionals to look after
cochlear implantees.
In addition, expanded use of implants will bring with it increased
technological sophistication that requires advanced professional
training. An example of this is optimally combining a cochlear implant
with a hearing aid, which will likely become the treatment of choice
for many cases of presbycusis in the near future. Cochlear implants
also provide abundant research opportunities for both basic and
clinical investigators with interests ranging from auditory physiology
to language development.
In addition to reducing the price of implants, we need to bring down
other technical, social, and cultural barriers to widespread adoption
of this technology. On the one hand, a certified program is needed to
ensure quality of service. On the other hand, it will be necessary to
diversify and broaden the training base that provides support for the
growing number of cochlear implant users, particularly in developing
countries where formal and advanced education infrastructure does not
yet exist.
For example, Dalhousie University helped China launch its first
audiology program, which has graduated more than 20 students. With
their financial resources, hearing device manufacturers could provide
intensive and specialized training as well as use their marketing
capability to increase public awareness of advanced technologies. On an
individual basis, hearing professionals can participate in and
contribute to these educational and training activities.
If all of us work together, we can help transform the lives of millions of deaf persons like Hua.
