*Calculations based on costs reported by
(Kaiser Family Foundation, 2000 and Saag, 2002)
While
this model was created for purely illustrative methods and remains
simplistic, it encompasses a "blue sky" theory in assumptions. The one
very striking calculation, however, is the obvious difference in cost
for a "healthier" population, as opposed to a "weaker" or at a more
advanced disease state population. These calculations argue for more
early intervention and early treatment. By providing that more
individuals are kept healthy, almost 36% or $9,000,000,000 can be saved
in expenditures.
Florida’s costs could be projected in a similar manner to the national
figures, but would be based on a smaller subset of 95,000 infected
individuals estimated by the Florida Department of Health. Other costs
not included in the calculations for both include the indirect costs
discussed previously.

*Calculations based on costs reported by

Based
on the previous calculations related to HIV/AIDS mono-infection, the
following tables represent the additional cost of treatment for HCV.
The CDC estimates a 25% co-infection rate between HIV/AIDS and HCV (CDC,
2002). However, the model used previously can be repeated, adding the
HCV treatment cost estimate of $15,000 into the cost per patient per
year (PPPY) for HIV/AIDS along the disease state estimates to calculate
the impact of HCV treatment costs on HIV/AIDS costs. Again, this model
is merely illustrative and must be considered a snapshot, especially
when taking into consideration the inherent differences between the
ongoing and eventually finite (until death) HIV/AIDS treatment and the
HCV treatment (6 months to 12 months for one course). It is for this
reason that HCV treatments cannot be annualized.

Similarly, Florida’s costs could be projected using a smaller subset of
the 95,000 infected individuals estimated by the Florida Department of
Health, multiplied by 25% to obtain the estimated co-infection rate.
This total would then become 23,750 HIV/AIDS/HCV co-infected
individuals. Other costs not included in the calculations for both
include the indirect costs discussed previously.

*Assumes treatment for 23,750

*Calculations based on costs reported by
(Kaiser Family Foundation, 2000 and Saag, 2002)
Assuming this co-infection rate and estimating the annual treatment
costs for HCV at $15,000, then a base $3.375 billion can be added to the
national HIV/AIDS subtotals to gain a general understanding of the
impact of HCV treatment on HIV/AIDS costs, while $356.25 million can be
added to the HIV/AIDS subtotals. One major gap in this model is the
lack of estimates for possible cost duplication of services, such as
doctor visits and other services which may not be mutually exclusive
between the two disease states. The estimate of $15,000 for the
treatment of HCV mono-infection from the New Jersey Correctional System
and Florida's Medicaid system includes such visits, which may or may not
be duplicative. However, the disease state of HCV (i.e. well vs.
advanced) of these distinct populations is unknown. A higher proportion
of individuals in advanced stage (i.e. liver failure up to and including
liver transplantation), for example, can greatly inflate the estimate.
The
“take home” message of these illustrative models is the argument for
early intervention. Using a model purported by Wong involving a high
degree (27.2%) of HCV clearance, 4.1% progression to moderate hepatic
status, 7.3% progression to compensated cirrhosis (no signs of liver
failure), and 1.5% progression to hepatocellular cirrhosis and
decompensated cirrhosis (liver failure), 3.1% of patients with either
compensated or decompensated cirrhosis would receive a liver transplant
(Wong, 1999). Calculating the impact of this cost could be shown as
follows. The average cost of a liver transplant, according to Walensky
et.al., is $200,000. If the previous population estimates (25% of
HIV/AIDS estimated population) are used to create a co-infection
population, and using Wong's 3.1% rate of liver transplantation, a model
can be created to estimate the need-based cost of transplants nationally
and in the State of Florida.

*Calculations using (Walensky et.al., 2002 and Wong, 1999)
As
with similar findings above, Wong concludes that, “economic savings
derived from preventing future cases of cirrhosis and hepatocellular
carcinoma more than offset the initial treatment cost” (Wong, 1999).
However, the actual cost would be far less for liver transplants because
of the reality of the low availability of transplant livers, coupled
with the fact that HIV/HCV co-infected individuals are less likely to
receive them due to their co-morbidity and low predicted long-term
success rate.
CURRENT
SERVICES AVAILABLE-Co-infection
Primary Care:
Primary care
doctors for hepatitis B and C, attained through private insurance, can
be located either by the consumer or by several local and national
groups that attempt to pair consumers with providers to best suit their
needs. Two examples of such resources include the American Liver
Foundation and Hep C-Alert. Both organizations have information on
doctors that either specialize in hepatitis treatment or have been known
to treat people with hepatitis.
The route to
treatment for people without health insurance or with public insurance
is through a national database provided by the U.S. Department of Health
and Human Services’ Bureau of Primary Health Care (BPHC) (http://bphc.hrsa.gov).
Via the Bureau, people
can locate community health services or “look-alikes,” i.e. doctors with
sliding fee scales or pharmaceutical programs, such as Roche’s
“Peg-Assist” and Schering-Plough’s “Commitment to Care” or “Patient
Assistance programs.” All of the pharmaceutical programs offer people
with both medical and financial need access to either free or reduced
price medications, usually for a limited time if they meet eligibility
criteria established by the program. It should be noted that the
pharmaceutical assistance programs are regarded as a “last resort” and
do not ensure continuous treatment.
In a one year
period in Florida alone, 4,503 individuals applied for Commitment to
Care (Schering-Plough's patient assistance program). Because they had
no other means of reimbursement identified by either the State or
Schering Plough, 1,392 individuals were approved and supplied with
Schering Plough's product. As part of the established program,
Schering-Plough employs reimbursement staff to work with applying
clients to identify eligibility possibilities such as the Veteran's
Association or Medicare Part B for therapy.
Additionally, the BPHC can locate Veteran’s Assistance (V.A.) treatment
centers. Groups such as Hep-C Alert also link uninsured persons with
pharmaceutical representatives and/or their physicians for reduced cost
medications.
The only
instance in which hepatitis will be treated at a hospital is in the case
of an extremely acute case, and hospitals cannot serve as primary health
care providers. Once treated for an acute infection, patients will have
to return to their primary health care providers, community health
centers, or county health departments.
Support
Groups:
There
are several support groups for people living with hepatitis in the state
of Florida. Support groups are located in Ft. Lauderdale, Tampa, St.
Petersburg, Broward County, Miami, Boca Raton, Gainesville, Orlando,
Palm and West Palm Beach and Plantation. Many of these groups are led
by local hospitals, hepatitis organizations, and national organizations
such as the American Liver Foundation. Locations of support groups are
found on the Internet, through local hepatitis or liver foundations, or
through hospitals. It is important to note that the majority of the
times listed for meetings are in the evening.
Programs Specific to
Florida:
In 1999,
Florida instituted its state-funded Florida Department of Health,
Hepatitis and Liver Failure Prevention and Control Program, administered
through county health departments. Initial appropriations were $2.5
million for the first year and $3.5 million the subsequent year. The
program began by serving six counties (Broward, Collier, Miami-Dade,
Monroe, Pinellas, and Polk) and their adult residents at an increased
risk for hepatitis A, B or C. Services include: a) enhanced
surveillance;
b) education of public
health providers; c) immunization against viruses A and B;
d) targeted intervention;
e) screening and testing for chronic hepatitis B and C and;
f) epidemiologic
investigations. In 2001, the program was extended to include hepatitis
A and B vaccine availability for the entire state, specifically for
people at increased risk for infection. The expansion also included
chronicity testing for adults with hepatitis B and C. Currently, the
original six counties receive continued funding, with limited funding
for three new counties, including Escambia, Lee and Seminole.
Links and Additional
Resources:
The
Department of Health, through the My Florida (myflorida.com)
website, offers a web-based clearinghouse containing 24 links to
websites and phone numbers for information regarding most aspects of
hepatitis. These sites include information from the CDC concerning
facts on the cause and spread of the disease and most common treatments;
groups dedicated to advocacy work; information about HIV and hepatitis
co-infection; information about screening, education and prevention;
Medicaid referral services, and locations of support groups. In addition
to the web resources, the Florida DOH also offers a toll-fee hepatitis C
Hotline, 1-866-FLA-HEPC. Additional resources, some of which assisted
in the research development of this work, include

RESULTS – PROVIDER SURVEYS
To
achieve a realistic perspective on hepatitis outreach, testing, and
treatment, a survey was developed to target providers from both the
public and private sector. Developed in collaboration between Florida
AIDS Action and the Florida Department of Health, Hepatitis and Liver
Failure Prevention and Control Program, the survey included many data
gathering methodologies. These techniques included open and close-ended
questions, Likert and ordinal scales, and ranking. The surveys were
mailed to a randomly selected number of private physicians, garnered
from a BPHC list, who identified themselves as hepatitis treatment
providers, as well as to all county health department hepatitis contacts
identified by the Hepatitis and Liver Failure Prevention and Control
Program. In addition to an introductory letter and a copy of the
survey, the Florida AIDS Action packet included a self-addressed,
stamped envelope to help with return rates. In order to increase
anonymity, no program specific or contact information was required.
Given a finite amount of time to complete the survey, respondents mailed
them to Florida AIDS Action. Research staff colored and numerically
coded each survey, and then entered the quantitative data into a
statistical computer package for analysis. Qualitative data were
entered into a coding system. Each data set was then cleaned and
analyzed. The following results summarize the responses of the survey
respondents.
The
respondents consisted of a blend of community health department/public
programs and private physicians, with a slightly larger percentage (10%)
of community health departments reporting. Despite not providing
incentives, having a randomized listing of private providers, and some
incorrect contact information gained from the hepatitis section within
the Florida Bureau of HIV/AIDS for county health department hepatitis
programs, the survey response rate was 24%. This percentage is higher
than what is routinely achieved when using written surveys.
Respondents
tested an average of 495 individuals for HBV ranging from 3-2,500
reported tests per provider. A majority of respondents (60%) do not
actively treat HBV. Of those that do provide treatment, they do so to an
average of 10 individuals ranging from 1-12. When asked why they
believe individuals seek testing for hepatitis B, 54.2% of respondents
indicated physician referral, 75% friend/spouse/partner/relative, 58.3%
blood bank, and 41.7% other. Interestingly, 100% and 70.8% indicated
they believed individuals do not seek testing because of Internet
research or public prevention education, respectively.
The majority
(87%) of respondents who answered why they believe individuals do not
seek testing for hepatitis B included either a lack of knowledge or
education, while over 20% indicated fear of the unknown. When asked why
they believe individuals seek hepatitis vaccines, 30.4% indicated
knowledge or education, 60.8% school, work, or travel requirements, and
26% indicated perceived risk, a prior exposure, or a hepatitis
diagnosis.
Most
respondents (60.8%) indicated a risk assessment tool when asked how they
determine an individual should be tested for hepatitis B, while 73%
indicated either a risk assessment tool or other risk categories when
asked how they determine an individual should be vaccinated.
Concerning HCV, respondents reportedly tested an average of 535
individuals ranging from no tests to over 2,500 individuals. A very
high percentage (68%) of providers reported that they do not treat HCV.
Of those that perform treatment, they do so to an average of 16
individuals ranging from 0-200.
When asked
why they believe individuals seek testing for hepatitis C, 2/3 (66.7%)
of respondents indicated physician referral,
friend/spouse/partner/relative, and blood bank. 45.8% indicated public
prevention education, 41.7% other, and only 4.2% because of Internet
research.
The
same majority (87%) of respondents who answered why they believe
individuals do not seek testing for hepatitis C, as was the case with
hepatitis B, included either a lack of knowledge or education, while
over 20% indicated fear of the unknown. When asked whom they consider
to be “at risk” for contracting hepatitis C, nearly 70% of respondents
cited IDU/drug use.
Most respondents (52%)
indicated a risk assessment tool when asked how they determine that an
individual should be tested for hepatitis C, while 65% indicated a risk
assessment tool combined with other risk categories.
When asked how effective
given modes of prevention education are, respondents rarely tended to
indicate “slightly ineffective” or “highly ineffective.” This indicated
that the majority of responders marked positive rather than negative
answers with regard to prevention outreach modes. Therefore, it can be
concluded that a non-answer may also be a negative answer. The “unable
to determine” percentage remained large for each response. For
television commercials, combined “slightly effective” and “highly
effective” responses yielded 54.2%, with 37.5% “unable to determine.”
For radio commercials, 50% and 37.5%, respectively; materials and/or
pamphlets 62.5% and 20.8%; peer educators 66.7% and 25%; and focus
groups 54.2% and 33.3%.
Respondents were asked
where they would prioritize hepatitis services for hepatitis C infected
individuals or those at risk, given unlimited resources (e.g. funding,
time, staff). Ordinal response options were one (1) through nine (9),
with (1) representing “most important” and (9) representing “least
important.”
Weighted tendencies were used to
analyze the responses, where (1) through (3), (4) through (6), and (7)
through (9) were grouped together. Of the scales that weighed toward
“most important,” testing totaled a combined 79.1%; prevention education
62.5%; 54.2% treatment; 49.9% vaccines; and 25% surveillance. Of those
that weighed toward “least important,” other social services (e.g.
transportation, housing, etc.) was given 87.5%; mental health 79.2%;
substance abuse treatments 37.5%; and case management 29.1%.
When asked if they thought
physicians and other medical staff require any additional training
and/or education with regard to hepatitis C infection, testing, and
treatment, an overwhelming majority of respondents (91%) indicated
“yes.” A follow-up question was then given, which asked what kind of
training and/or education they would suggest. The majority of common
responses included updates regarding treatment, testing, and
surveillance changes.
Regarding the treatment of
HIV co-infected individuals, both past and present, 34.8% indicated a
positive response. For respondents who treat or have treated those who
are co-infected, the final question asked was what they thought were
special issues to be considered when treatment, prevention education,
and the provision of social services occur. Responses varied among
prevention education, medication interactions, depression, holistic
health strategies, and hope.
The survey and its results
were found to be very useful in creating recommendations for current
practices in viral hepatitis outreach, prevention, treatment, and other
cost projection activities. Florida AIDS Action views the answers of
current employees dealing with related issues from both public and
private sectors to be paramount to policy making and policy altering
decisions.
SERVICE COSTS
PROJECTIONS
Following
investigations into disease manifestations, their treatment theories,
and how they are, in fact, impacting the community, it is most
beneficial to investigate how this impact will be felt economically.
Given the uneasy reliance on surveillance projections and the
complicated science of drug pricing, projecting costs remains a
difficult endeavor.
Projection
models for service costs are dependent on the interaction of two other
projections: the estimated “burden” of disease (prevalence) and the
future costs of treatment. Further complicating the model are
methodological data collection problems, changing treatment standards,
differing response levels, recurrence, and unknown weights or factors
that can significantly undermine the quality of the data.
The value of
each model is dependent on the combination of epidemiological,
demographic, and behavioral trends. Different methods are used to
determine differing
rates of interest. It
should be noted that HIV incidence, HIV infection prevalence, AIDS
incidence, and AIDS prevalence and mortality are interrelated, yet
separate concepts. Each are associated with time.
From a
prevention perspective, HIV incidence is of particular interest. The
infection prevalence, or pool of those currently infected, represents
the potential for future incidence and the effect of past incidence.
Although current rates of transmission can be calculated from prevalence
rates, reflecting the experience with the disease among those that have
already acquired it, future incidence is still dependent on personal
behaviors.
AIDS
incidence can also be used to calculate HIV prevalence by subtracting
cumulative AIDS deaths from cumulative incidence. Using a standard rate
of progression from HIV to AIDS, the figures are worked backwards to
estimate past HIV incidence. The standard rate of progression has been
10 years, and is commonly employed for this type of analysis.
Adjustments that take into consideration the impact of HAART are
constantly needing revision.
Serologic surveys, such as NHANES, are used to find the status of
participants. Because the participants are selected at “random,” their
status is extrapolated to others of the same category within the
population. Census numbers are used to determine the population
figures. The problems with this method are the issues of “random” and
representation.
Many
countries have employed active surveillance systems. Instead of relying
on individuals to come into the system, current levels of HIV infection
are determined by testing samples of blood and other bodily fluids
obtained for other routine screening purposes. Since the specimens are
anonymous, the tests capture specimens of those that refuse to be tested
for HIV.
IMPACT ANALYSIS:
Medicaid
According to the Florida Agency for Health Care Administration (AHCA),
total spending for all hepatitis C patients enrolled in the MediPASS
program for fiscal year 2000-2001 totaled $76,824,541. This sum,
divided by 62,174 total case months, yields a $1,236 per member per
month (PMPM). A person undergoing annual hepatitis C treatment will
incur a cost of approximately $15,000, which is consistent with findings
in the New Jersey prison system cited previously.
Of
those patients with AIDS who are treated for hepatitis C under the
MediPASS program, overall costs amounted to $23,162,195, representing
30.1% of all patients treated for hepatitis C. Divided by 10,319 case
months, PMPM rises 81.6% to $2,245. The cost for a person with AIDS
undergoing annual hepatitis C treatment is approximately $26,940.
IMPACT ANALYSIS: The AIDS Drug Assistance
Program (ADAP)
Sixteen state ADAP programs have already been forced to cut
back on HIV services due to budget problems, increased enrollment,
longer duration periods, and rising healthcare costs, with more expected
to follow. Current reports on the status of ADAPs are maintained by the
National Alliance of State and Territorial AIDS Directors (NASTAD)
ADAP Funding Watch Report.
Eligibility and drug
formulary restrictions, as well as waiting lists, are commonly used to
limit expenditures. Effects include treatment gaps and patient
migration. Without consistent access to medications, which help to keep
viral loads down, time becomes a very real threat. While some patients
are forced to wait-and-see, others will actively migrate to locations
that can provide treatment, blurring the historical trend lines
capturing geographic need and making them incongruous to “estimated”
demand.
Even with these problems involving the treatment of HIV
alone, there is a sustained need for those that are HCV co-infected.
New Jersey and Massachusetts were surveyed in order to assess the
possible impact of HCV services on the Florida ADAP, which does not
currently provide them. In New Jersey, out of 3,000 ADAP clients, in
one month, 29 clients accessed Ribavirin and 35 accessed
Peg-Interferon. This was at a cost of approximately $86,000 for the
month to provide treatment to all of these clients (personal
communication with Ronald Weinstein, New Jersey ADAP Director, April 23,
2003). Using these figures, out of a total ADAP budget of $55 million
per year, the projected cost, given a somewhat consistent need, would be
$1 million spent on hepatitis C treatments. This would account for less
than 2% of their total budget.
When the Massachusetts ADAP
was surveyed, it was found that out of the 1,106 ADAP clients served in
one month, five (5) clients accessed HCV medications. A combined total
of $2,635.26 was spent on Ribavirin and Peg-Interferon for the month of
December 2002. For the 2002 fiscal year, the total ADAP budget for the
state of Massachusetts consisted of $14 million, $8 million of which was
spent on pharmaceuticals and $6 million on insurance continuation and
other programs (personal communication with Annette Rockwell,
Massachusetts HDAP Coordinator, April 29, 2003). If the December total
for New Jersey is generalized to each month, without making exceptions
for treatment failure and other confounding factors leading to shortened
length of treatment, Massachusetts would spend around $32,000 a year for
HCV treatments. This sum would account for less than 1% (.2%) of the
total ADAP budget and less than 1% (.4%) spent on pharmaceuticals.
