- Congestive Heart Failure (CHF)
CHF is a disorder where the heart loses its
ability to pump blood efficiently. This dysfunction
impairs the provision of sufficient oxygen and
nutrients to the body's muscles and organs.
While there are many causes of CHF, the two
most frequent are hypertension and coronary
artery disease. For many people, CHF is a progressive
disease that eventually leads to death. Over
five million people are estimated to have CHF
in the United States. It is the only major cardiovascular
disorder that is increasing in incidence and
prevalence.
CHF patients are classified into four categories
based on the degree of the disease. People with
class III and IV CHF experience significant
health effects and are typical candidates for
the BL Healthcare monitoring system. Patients
in these two classes represent 25% of all CHF
patients. This means the total number of patients
in the United States who would be suitable for
remote CHF monitoring with a BL Healthcare approach
is about 1.25 million, with a net annual increase
of approximately 40,000. Approximately half
of these are over 65.
In addition to afflicting a significant number
of Americans, CHF is also the most expensive
medical illness in the United States. The American
Heart Association estimates that $24.3 billion
is spent on health care for CHF patients each
year, representing about 1.7% of total health
care expenditures. Of this, almost $10 billion
is related to hospitalizations alone. The large
portion of patients with serious disease and
the significant opportunity to both improve
the health of these patients while lowering
the cost of care, make CHF an attractive area
in which to develop home health management solutions.
Continuous vital sign monitoring, rich education
videos, periodic video consultation with nurses,
doctors and care givers to keep the symptoms
under control and avoid hospitalization.
- Diabetes
Diabetes is a disease in which the body fails
to produce or properly use insulin and therefore
cannot adequately break down sugars and starches
needed for life. Over 11 million people have
been diagnosed with diabetes, with an estimated
6 million more still undiagnosed. Over 20% of
persons 65 years of age and over have diabetes.
It is the sixth leading cause of death in the
United States, accounting for over 200,000 deaths
per year.
Diabetes has a significant societal and economic
impact as well. The National Diabetes Information
Clearing House estimates the direct medical
costs total about $92 billion per year, while
the indirect costs (loss of work days, etc.)
total about $40 billion. Uncontrolled diabetes
often exacts a devastating toll over time: high
blood pressure, blindness, end-stage kidney
disease, peripheral circulatory problems, and
heart disease are all common complications.
The high rate of complications or comorbidities
with this disease, combined with the patient's
need for constant monitoring of glucose levels,
provides an opportunity for technology to improve
the lifestyle of these diabetics.
It may be conservatively estimated that approximately
15% of the diabetic population, almost 1.8 million
people, are suitable candidates for BL Healthcare
technology. Simple interface that uses television

- Chronic obstructive pulmonary disease
(COPD)
COPD is characterized by airflow obstruction
with breathing-related symptoms such as chronic
cough, exertional dyspnea, expectoration, and
wheeze. Although COPD is a nonspecific term
referring to a set of conditions that develop
progressively as a result of a number of different
disease processes, it most commonly refers to
chronic bronchitis and emphysema and a subset
of patients with asthma.
COPD is now the fourth leading cause of death
in the United States, and it is the only common
cause of death that is increasing in incidence.
The medical impact of COPD in the U.S. includes
over 16.2 million office visits, 1.4 million
ER visits, 668,000 hospital discharges, 1.9
million hospital days, and 123,013 deaths in
2001 (National Center for Health Statistics).
According to the National Heart Lung and Blood
Institute the annual costs of COPD are above
$32 billion, with over $18 billion due to medical
costs, and the other $14 billion from other
indirect costs. It is estimated that about 15.3
million Americans live with COPD, with about
20% being people with emphysema. Of this total,
approximately 3.8 million have severe enough
disease to benefit from more intensive medical
monitoring and management.
- Asthma
Asthma has grown to epidemic proportions over
the last 15 years. Over 30 million Americans
living today have lived with asthma at some
time in their lives, and 22 million are currently
diagnosed with asthma, with 6.6 million of these
under 18. The disease disproportionately affects
children, minorities and those in poverty. It
is the most common chronic disease in those
under 18. If it continues to grow at present
rates, it will affect 14% of the population
by 2020. Nearly 500,000 hospitalizations and
9.5 million physician office visits were attributable
to asthma in 1999, while 45-50 million asthma
exacerbations were treated in emergency rooms
and clinics. Asthma is associated with significant
morbidity and mortality. In 1999, asthma was
the cause of death in nearly 5,000 Americans.
Asthma entails an annual economic cost to the
nation in direct health care costs of $9.4 billion;
indirect costs (lost productivity) add another
$4.6 billion for a total of $14.0 billion. Inpatient
hospital services represented the largest single
direct medical expenditure, over $4 billion.
The value of reduced productivity due to loss
of school days represented the largest single
indirect cost at $1.4 billion. Among this population,
5% (over a million people) experience severe
symptoms or unstable disease that exacts a large
human toll, requires significant medical expenditures,
and would easily benefit from enhanced monitoring
and management.
