Introduction
The Medicare program was originally designed in 1965 to
mirror the standard health insurance of the times, Blue Cross/Blue Shield, which
meant coverage for major medical (inpatient hospital coverage) and basic
outpatient coverage (doctors and related services). While there have been
many changes in health care and the Medicare population in the years since 1965,
there are a few important changes in the population that affect how well the
program serves its target population.
Advances in medical science and technology – new diagnostic
and treatment procedures, new equipment and new pharmaceuticals -- allow people
to live longer with medical conditions that require on-going care and treatment.
Taken together, these facts mean that the fact of the Medicare population has
changed. We have a Medicare population that is more elderly and typically
has multiple chronic conditions that require on-going care. Unlike its
beginnings, the Medicare program now covers people with End Stage Renal Disease
and most recently, Amyotropic Lateral Sclerosis (ALS) . There is also a
younger, disabled population entitled to the program, making up about 13% of the
program population. The changed nature of the program population may
indicate that the acute, episodic care orientation may no longer be sufficient
to address some critical needs of the population.
This paper provides a profile of today’s Medicare
beneficiaries using the Standard Analytic File for 1999 and the Household
Component of the Medical Expenditure Panel Survey (MEPS) from 1996. The
focus of the analysis is clinical; we examine medical service use and diagnosis
for chronic conditions rather than functional limitation and long term care
needs. [i]
The analysis of SAF service utilization data excludes persons who died during
the survey year in an attempt to extract the effect of end of life care on
service utilization and costs. This can only be considered a crude
adjustment since clearly there were people at the end of life during the survey
year who died after the survey year.
To conduct this analysis, we looked at the SAF and MEPS data
in two ways. First we broke out utilization by Medicare eligibility status
and age. To do this, we broke out and analyzed separately the under 65
year old ESRD, under 65 disabled, and under 65 ESRD with disability, and also
examined the 65 and older plus population in increments of 5 years beginning at
65 and grouped the 85 years and over population together. We then looked
at the population by number of chronic conditions – all those in each data set
with no chronic conditions, one chronic condition, two such conditions, etc. (as
determined by claims or self-reported conditions in the case of MEPS).
People with five or more conditions were grouped together.
In order to think about care of Medicare beneficiaries with
chronic conditions, it is helpful to define, or at least distinguish, among
terms. Acute care, most people would agree, is care delivered on an
episodic basis to treat or cure acute illness, or to treat acute exacerbations
of a chronic condition. The need for long term care arises from a need for
human or technological assistance in Activities of Daily Living (ADLs) or
Instrumental Activities of Daily Living (IADLs). Often, debilitation
stemming from the effect of one, or more than one, chronic condition results in
the need for long term care services.
Chronic care is often thought of as the array of services
represented by the acute and long term care systems brought together to treat
and serve frail elders with chronic conditions. However, chronic care can
have a more clinical focus and can be thought of as a gray area between acute
and long term care services. This approach may be more appropriate for
thinking about design of health coverage programs such as Medicare that are
medically oriented and are likely to remain so for the immediate future.
Chronic care then, can be clinically-oriented, ongoing medical care, management
and prevention for people with (multiple) chronic conditions organized to
maintain health status, slow disease progression and maintain functional status
of the individual.
Chronic Conditions
The top five chronic conditions in the Medicare population
overall are: hypertension, diseases of the heart, diseases of the lipid
metabolism, eye disorders, and diabetes.[ii]
There is not a great deal of variability by age or eligibility status in the top
disease rankings although some of the variability highlights include the
following.
· There is little
variability in disease rankings in the 65 to 85 year old populations but some
variability in the ESRD and disabled populations relative to the aged
population.
· Senility and
organic mental disorders are most prevalent in the 85 years and older population
but begin appearing among the top 15 conditions in the 75 – 79 year old group.
· Affective
disorders are the fifth most prevalent group of conditions for the disabled
population but rank 13th for the general Medicare population. Other conditions
related to mental health appear more prevalent in the disabled population than
in the aged Medicare population.
· Asthma is one of
the top 15 most common conditions among disabled Medicare beneficiaries but
asthma is not otherwise very prevalent in the Medicare population.
General Prevalence and Cost
About 78% of the Medicare population has at least one chronic
condition while almost 63% have two or more. Of this group with two or more
conditions, almost one-third (20% of the total Medicare population) has five or
more chronic conditions, or co-morbidities.
Aged beneficiaries make up at 87% of the program population,
13% are eligible due to disability and under .4% have end stage renal disease.
Spending on people with ESRD constitutes just over 3% of program expenditures
and spending on the under-65 disabled equals about 11% of program costs.
Within the disabled population, the SAF data indicates that
38% do not have a chronic illness (two claims in the year for a condition
defined as chronic).[iii]
In general, the prevalence of chronic conditions increases with age – 74% of the
65 to 69 year old group have a least one chronic condition, while 86% of the 85
years and older group have at least one chronic condition. Similarly, just
14% of the 65-69 year olds have five or more chronic conditions, but 28% of the
85 years and older group have five or more. (Fourteen percent of the
people with disability-related eligibility have five or more chronic conditions
but 46% of the ESRD patients have five or more.)
Of the Medicare beneficiaries with a chronic condition (78%
of all beneficiaries), those aged 70-74 make up the largest proportion of those
with one or more chronic conditions – 23%. Those 85 and over are 11% of
the total Medicare population with any chronic condition. People with
disability-related eligibility are 10% of the chronically ill population.
Of total beneficiaries without a chronic condition, the largest segment is the
65-69 year old population, who make up 27% of all those without a chronic
condition, followed by the people with disabilities who constitute 23% of the
non-chronically ill group. Prevalence of multiple chronic conditions
increases with age. Among beneficiaries with five or more chronic
conditions, those 80 years and older are 31% of cases whereas they are only 19%
of cases with one chronic condition.
Average per beneficiary spending does not vary all that much
by age, when viewed against number of chronic conditions. For example,
among age-entitled beneficiaries with five or more chronic conditions, average
per beneficiary spending is $13,300 for people aged 65 – 69, and $13,400 for
those 85 and over. For aged beneficiaries with one chronic condition,
average per beneficiary spending for those 65 – 69 years old is $870 while it is
$1,100 for those over 85 years.
In contrast, there is significant variation in costs when viewed by number of
chronic conditions without regard to beneficiary age. Average per person
costs for people with no chronic conditions was $160 (including the under 65
entitled), while the average per person cost jumps to $13,700 for people with
five or more chronic conditions. The average per beneficiary spending
across all ages and eligibility groups is $4,200. Per beneficiary spending
increases more than 2 ½ times between two and four chronic conditions, and
nearly triples again from four to five chronic conditions.
People with one chronic condition are 15% of the Medicare
population but only 3.5% of the spending. People with 3 chronic conditions
are also 15% of the population but 10%
of the spending. People with 5 chronic conditions are
20% of the population but 66% of program spending. (This analysis remains
essentially unchanged when the ESRD and disability groups are removed from the
calculations. Because they are about 13% of the total beneficiary population but
the bulk of this group, those with disabilities, have average utilization and
spending that tracks the younger segments of the age-related eligibility group.)
Average per person spending for the age-entitled beneficiaries varies very
little within among those with one chronic condition. This is true in each
grouping of people by number of chronic conditions. In general there is an
increase in average per beneficiary spending as age increases.
Inpatient Utilization
Inpatient utilization does not vary all that much by age
although it does vary significantly for groups not eligible by age. The
average length of stay (LOS) for all beneficiaries is 10.3 days and 19% of the
population has an inpatient stay. ESRD beneficiaries have much higher
rates of hospitalization and longer lengths of stay than aged beneficiaries.
When we examined the service utilization by number of chronic
conditions, a strong pattern emerged of increasing costs and utilization as the
number of conditions increase. Fifty-five percent of
beneficiaries with five or more conditions experienced an inpatient hospital
stay compared to 5% for those with one condition or 9% for those with two
conditions. Inpatient days per thousand beneficiaries jumps from 335 days for
those with one condition to over 7000 days per thousand among those with 5 or
more conditions. The average days per thousand across all beneficiaries
was 1944 (1833 if the under-65 are excluded).
Physician Services
In terms of physician visits, the average beneficiary has
just over 15 visits annually and sees 6.4 unique physicians in a year.[iv]
ESRD-eligible beneficiaries see 13 unique physician and have almost 38 visits
annually while disability-related eligibles average 5 unique physicians and have
an average of 13 visits annually. In contrast, people who are 85 years and
older have almost 18 visits in a year and see 6.9 different doctors. Like
inpatient services, physician service use is highest for those aged 80 – 84
years old; they have just over 18 visits with just over 7 different unique
doctors.

Once again, a more compelling pattern becomes apparent when
physician service is evaluated against numbers of chronic conditions.
Comparing usage by age, there is an increase of 40% in the number of physician
visits by people aged 85 and older relative to visits by people aged 65 – 69.
In contrast, there is almost a four-fold increase in visits by people with five
chronic conditions compared to visits by people with one chronic condition.
The number of unique physicians seen increases almost two and half times for
people with five or more chronic conditions relative to those with just one
chronic condition.
Prescription Drug Utilization
Because Medicare does not cover outpatient prescription
drugs, we used the MEPS 1996 Household Component to look at usage. We
analyzed reported prescriptions for those under 65 who reported being enrolled
in Medicare for at least six months during the survey period, and looked at the
people at least 65 years old, grouped into increments of five years. An
important caveat to this analysis is that the public use file provides
information on all prescriptions filled – including free samples and refills.
It is not possible to easily disentangle numbers of unique prescriptions from
the data file. We did not adjust the file to extract out those who did not
complete the survey because it is not certain that they died and because
prescription drug use may not follow the same pattern of increased intensity in
the last months of life as hospital and physician services do.
Using MEPS 1996, we found that the average Medicare
beneficiary fills almost 20 prescriptions (19.7). Within this average, the
under 65 year old population fills on average 26.3 prescriptions and those 65
years and older fill 19.1 on average. We found that beneficiaries with no
chronic conditions fill an average of 3.7 prescriptions per year while those
with any chronic conditions fill an average of 22.7. Among those with any
chronic conditions, there is a relatively small difference between the under 65
and over 65 groups – 28.2 prescriptions versus 22.1 prescriptions respectively.
The utilization among the under 65 year old population
generally slightly exceeds the utilization of the 85 year old and over
population. This is true in all categories but the differential is
greatest among those with either one or five chronic conditions. It is
also interesting to note that, in contrast to service utilization patterns,
prescription drug utilization is higher for those 65 – 69 with two or more
chronic conditions than it is for those 85 years old and older. The data
do not provide many clues as to why this may be the case.
While there are some interesting highlights in the
age-related analysis, once again the stronger trends become obvious when the
data are viewed through the lens of number of chronic conditions.
· Average annual
prescriptions filled jumps from 3.7 for all people studied with no chronic
condition to 49.2 for people with five or more chronic conditions.
· Growth in usage
between those with no chronic conditions and those with one chronic condition is
over 180 percent – from 3.7 to 10.4 prescriptions filled.
· Usage grows 72%
between one and two chronic conditions, from 10.4 to 17.9 prescriptions filled.
· There is a 48%
growth in average annual usage between four and five chronic conditions (33.3 to
49.2).
Unlike other utilization, there are some interesting findings
when one examines the data by age group and number of chronic conditions.
As mentioned earlier, prescription drug usage increases are most significant
between people with no chronic conditions and those with one chronic condition.
Within this growth, the increase is highest for those aged 65 to 69 years old
where there is a 300% increase in prescriptions filled from those with no
chronic condition to those with one chronic condition. For the under 65
year old Medicare population, usage increases 87% between zero and one chronic
condition; usage increases most substantially for this group again between four
and five or more chronic conditions (83%). Increased usage among the 85
years and older population between zero and one chronic condition is 138%.
For this age group, usage growth rates slow or steady to between 30% and 45% in
average number of prescriptions filled with each additional chronic condition.
Even though the average annual number of prescriptions filled
increases in number with each additional chronic condition for all age groups,
the percentage growth is uneven. The percentage growth in average
annual number of prescriptions declines between four and five chronic conditions
(relative to the percentage growth among other chronic condition groupings) for
the 75 - 79, 80 – 84, and 85 years and older groups whereas the percentage
growth steadily increases for the under 65, 65-69, and 70 – 74 year old groups
relative to other groupings of chronic conditions. It is not clear from the data
why relative usage declines among the oldest while co-morbidities increase.
Utilization and Care Coordination
So what does all this information mean for beneficiaries and
for the program that serves them? There are indications in the data that there
is a lot of care provided to beneficiaries with chronic conditions –
particularly those with multiple chronic conditions. There are also indications
that the care may not be well-coordinated and that for beneficiaries with
multiple chronic conditions there are adverse outcomes.
Researchers at Johns Hopkins (Wolff and Starfield,
unpublished) have found that as the number of chronic conditions increase, so
too do the number of inappropriate hospitalizations for illnesses that could
have received effective outpatient treatment (Ambulatory Care Sensitive
Conditions). Per 1000 beneficiaries, these hospitalizations increase from
seven for people with one chronic condition to 95 for beneficiaries with five
chronic conditions, and jumps again to 261 for people with 10 or more chronic
conditions.[v]
Given that beneficiaries are receiving many medical services,
it may be reasonable to speculate that greater coordination is needed
particularly for those with multiple or co-morbid, conditions. It may be
that different providers are recommending conflicting treatments that result in
poor outcomes including adverse drug events. It could be that one condition is
receiving treatment while other chronic conditions go unattended and then flare
up into acute episodes. The work of Wolff and Starfield seems to indicate
that people with multiple chronic conditions careen from one acute exacerbation
to another, a result of a series of unattended co-morbidities.
Implications for Medicare Program Reform
The data compellingly document that Medicare is a program for
people with one or more chronic conditions. Yet, the structure of Medicare was
modeled after indemnity insurance programs in existence when Medicare was
enacted into law in 1965 and was not designed to care for people with chronic
conditions.
In his seminal article, “Uncertainty and the Welfare
Economics of Medical Care,” Nobel laureate Kenneth Arrow, writing in 1963,
discussed the issue of “moral hazard” in insurance. (Arrow) That is, “what is
desired in the case of insurance is that the event against which insurance is
taken be out of the control of the individual.” Otherwise, “moral hazard.” Arrow
emphasized that insurance is more valuable the greater the uncertainty of the
risk being insured against, the reason, he explains, for putting greater
emphasis on insurance against hospitalization and surgery than other forms of
medical care.
In this context, Arrow commented specifically on the merits
of insurance against chronic illness. “On a lifetime insurance basis, insurance
against chronic illness makes sense, since this is both highly unpredictable and
highly significant in costs. Among people who already have chronic illness, or
symptoms which reliably indicate it, insurance in the strict sense is probably
pointless.”
Passed less than two years after Arrow’s article, Medicare
reflected the indemnity insurance model of covering unanticipated and unwanted
events and not aspects of care that are predictable and desirable for patient
and provider. Over time, of course, the traditional Medicare program has evolved
somewhat to better reflect the growing reality that the program in many ways
provides a social insurance-based pooling mechanism for prepaying for
predictable medical services and is not just an insurance program in the “strict
sense.” Nevertheless, despite coverage for specific prevention services in
statute, limited coverage for patient education, such as for diabetes, and a
modest reorientation of the physician fee schedule to better compensate
so-called evaluation and management services, the program maintains an indemnity
insurance orientation that does not support improved forms of care for the large
majority of beneficiaries who have chronic conditions.
In the fee for service environment, care for beneficiaries
with chronic conditions can be characterized “as fragmented and poorly
coordinated across multiple health care providers and multiple sites of care.
Evidence-based practice guidelines have not always been followed, nor have
patients been taught how best to care for themselves. These shortcomings are
particularly true for patients served under reimbursement systems in which
providers lack incentives for controlling the frequency, mix, and intensity of
services, and in which providers have limited accountability for the outcomes of
care.” (CMS web site)
Wagner and colleagues have identified a number of elements of
a Chronic Care Model. (Wagner) The new interventions cluster in six areas:
health care organization, community resources, self-management support, delivery
system design, decision support, and clinical information systems. Some of
these elements are not directly related to Medicare payment policy, but a few
depend crucially on the ability to achieve adequate compensation. For example,
in the area of patient self-management, the acquisition of patient
self-management skills occurs outside of clinical encounters and involves
personnel who are not reimbursed under Medicare payment rules. Similarly,
delivery system design requires the coordinated actions of multiple caregivers,
including clinical case manager functions, performed by chronic disease nurses
or pharmacists, again, non-reimbursable activities under current rules.
Even straight-forward and desirable use of telephone contact
– or email -- to enhance appropriate patient follow-up to treatment regimen
cannot easily be covered in an indemnity insurance context because of concerns
about relatively high administrative costs to process telephone call claims,
potential fraud and abuse, and potentially high use patterns for such an easily
assessed and desired intervention, i.e., the results of moral hazard.
The Potential of Capitation
Even in 1965, when Medicare was enacted, there were
alternative financing and organizational approaches that combined service
delivery and insurance, the so-called prepaid group practices, such as
Kaiser-Permanente and Group Health Cooperative of Puget Sound. In some ways,
these organizations are better positioned to administer services for patients
with chronic conditions than the traditional fee for service program. One of the
main reasons is that they rely on capitation as a financing mechanism, rather
than piece-meal payments to each individual provider that might be involved in
the care of patients. “In a capitated environment, organizations bearing
financial risk have strong financial incentives to identify their high-risk
members early and to provide them with special care designed to optimize their
health and avert health-related crises. They have longer-range incentives to
promote continued good health among older enrollees who are not chronically
ill.” (Boult, 1999)
Capitated plans can be much more flexible than the
traditional Medicare program in establishing innovative services, and many of
the innovative programs for patients with chronic disease have been based in
health maintenance organizations. Unfortunately, capitated risk-contracting in
Medicare is not doing well at this time – for reasons that go well beyond the
scope of this paper. One of the basic problems is that the Section 1876
risk-program and its successor, Medicare + Choice, were designed to reward plans
caring for relatively healthy beneficiaries who were attracted to plans offering
additional benefits beyond the statutory Medicare benefits. Although
theoretically, development and implementation of a powerful, health
status-based, risk adjustment method would give health plans incentives to
actively market to beneficiaries with chronic diseases, currently, difficult
implementation issues makes the future of risk adjusted payment to health plans
uncertain. Indeed, the future of the Medicare+Choice program is uncertain, and
the logic of capitation as a primary vehicle for stimulating innovation in care
for the chronically ill unproved in Medicare
Within the traditional fee for service program, two sets of
demonstrations targeted to beneficiaries with chronic disease are getting
started. On January 19, 2001 CMS announced selection of 15 demonstration sites
under the Medicare Coordinated Care Demonstration, authorized by the Balanced
Budget Act of 1997. Providing case management and disease management
services, organizations will provide “comprehensive planning, patient education,
and ongoing monitoring between doctor visits to improve self-care… In addition,
some of the projects will offer participating beneficiaries additional benefits
aimed at removing barriers to prompt medical care, such as coordinating with
community-based services, transportation, assistance with medications,
non-covered home visits, and medical equipment.” (CMS website)
The Medicare, Medicaid and State Child Health Insurance
Program Benefits Improvement and Protection Act of 2000 (BIPA) set up an
additional demonstration program testing disease management programs for
beneficiaries with advanced-stage congestive heart failure, diabetes, and
coronary heart disease. CMS recently solicited applications under this program,
which could result in three awards covering up to 30,000 beneficiaries at a
time. Prescription drugs would be covered under these demonstrations and the
demonstrations would be required to meet strict budget neutrality
requirements.
The coordinated care and disease management demonstrations
importantly focus on organizational accountability for caring for beneficiaries
with chronic conditions, trying to achieve in the fee for service program the
kind of program innovation that some prepaid group practices have accomplished.
Incremental Improvements in the Traditional Program
There may be opportunities for some program enhancements that
would represent incremental improvements in the traditional indemnity-oriented
Medicare program. As documented earlier, the majority of beneficiaries have one
or more chronic diseases. Some have called for a range of services to be
available to beneficiaries who have a certain number of ADL or IADL limitations.
Although reflective of functional status, basing eligibility on ADLs has certain
drawbacks. First is the fact that ADLs and IADLs are typically measures of the
need for personal assistance, i.e., measures of the need for long-term care. But
Medicare does not provide long term care services, but rather medical services.
It would be difficult for a program with an acute/subacute care statutory basis
to adopt and implement a long-term care eligibility standard. Second, consistent
with the need to assure equitable access to covered benefits, eligibility should
not be predicated on an assessment conducted by specialists, in this case,
geriatricians, or institutions that are not generally and widely available.
Rather, eligibility should be determined by commonly accessible physicians who
may well lack specialized expertise. The general physician would not be able to
assess or authorize services based on ADL/IADLs and might be even less able to
document clearly a decision that would withstand review.
Rather than using ADLs, we would recommend considering
eligibility for additional benefits based on clinical status, as is done in the
current program. For purposes of discussion, beneficiaries with four or more
serious chronic conditions could be the target group. It might well be that
further analysis would permit creation of a subset of chronic conditions that
are associated with higher costs and would become the conditions that determine
eligibility for additional payment or services. Consistent with planned
implementation of health status based risk adjustment in the M+C program,
physicians would be expected to identify patient diagnoses through assessment
and documentation, within their scopes of practice.
A clinical condition based approach could more readily
predict the numbers of eligible and better anticipate program costs than one
based on measures of functional status.
For beneficiaries who qualify based on the presence of the
requisite number of serious conditions, higher payments for office based care
would be made. This enhanced payment could be billed by any and all unique
physicians who see the patient for each office visit. The higher payment would
more generously compensate physicians for the greater amount of time they and
their staffs need to care for patients with serious chronic conditions and to
coordinate with other treating physicians and other professionals who are caring
for the patient.
Unlike a broad based payment available to all physicians, a
more targeted approach might be a clinical case management model whereby a
treating physician accepts added responsibility to coordinate the clinical care
provided by all treating physicians. In the managed care environment, this
approach has received the pejorative appellation of a “gatekeeper,” because of
the emphasis on requiring the designated physician to approve all referrals to
specialists and for many ancillary tests and procedures.
Medicaid has a parallel mechanism called the Primary Care
Case Manager (PCCM) model. In Medicaid, a beneficiary selects or is
otherwise assigned to a primary care doctor who acts as a care coordinator and
primary care provider. The model has changed somewhat since it was first
implemented in Medicaid and in some cases the care management aspect has been
weakened over time, but it may still have relevance for needs in the Medicare
program. Physicians in this role are paid in one of two ways: a monthly per head
management fee which is separate and apart from billing for specific services
rendered, or a monthly capitation to the physician for a range of primary care
services and the care coordination activities.
A number of design issues would have to be considered in
applying a PCCM-type approach to Medicare. Whereas these programs are typically
required in managed care and in Medicaid applications, the strong Medicare
tradition would be to make it voluntary for the beneficiary, perhaps in exchange
for reduction of some cost-sharing obligations or discount off of the part B
premium. Although the desirability of having a single physician coordinate care
might be relevant for all Medicare beneficiaries and might be promoted in
program guidance and educational materials, specific reductions in cost-sharing
requirements might be limited to those with a certain number of chronic
conditions, as discussed above.
For their part, physicians could participate to the extent
that they agreed to follow certain administrative procedures to track and
monitor all aspects of a beneficiary’s care, act as a referral, receive and
coordinate clinical reports from others involved in the patient’s care, maintain
a robust medical record and be available to provide greater consultation time
surrounding a qualified beneficiary’s care. An outstanding issue is whether
specialists who agree to these requirements would be designated as the case
managing physician for Medicare beneficiaries, given the prevalence of certain
chronic conditions that are commonly cared for by specialists, e.g.,
cardiologists. Inserting another physician – a primary care physician – into the
mix of specialists already caring for a beneficiary with multiple chronic
conditions may not be warranted if one of the specialists is willing and able to
carry out the coordination functions this model requires.
A logical payment approach for Medicare would be a monthly
capitation fee for care management services, in addition to standard fee for
service reimbursements for discrete physician services that are reimbursed under
the Medicare fee schedule. An alternative would be to bundle standard primary
care services into a much larger monthly capitation amount. Medicare actually
has experience with monthly capitated payments for covered physician services in
the payment system for renal physicians under the ESRD program. As alluded to
above, capitation provides greater flexibility than fee for service payment and
may be more conducive to implementing delivery system innovation, along the
lines of the Chronic Care Model, outlined above. However, primary care
capitation can have untoward incentives to stint on care and, depending upon
whether capitated physicians are at risk for referrals and hospitalizations, may
have an incentive for inappropriate referrals.
One approach would be to pay a monthly capitation care
management fee to designated physicians while maintaining fee for service
reimbursement for discrete physician services for physicians practicing in solo
and small group practice, while encouraging the expanded capitation option for
physicians practicing in large, multispecialty group practices that have the
administrative infrastructure and financial wherewithal to manage larger
capitation amounts.
Under either payment structure, the model would require some
sort of provider designation such that participants would have to meet certain
standards for care, quality, and administrative capabilities. Because only
one provider can be paid for the clinical care management of a particular
patient, more administrative capabilities may be required of the carriers,
although the precedent already exists in limiting services under the traditional
program for those enrolled in M+C.
Beyond administrative structures that can facilitate greater
coordination of clinical care, it may be appropriate specifically to consider
benefit design that can facilitate greater clinical care coordination and
management. One such approach would be a modified, home visit type of benefit.
The current home health benefit is for people in need of extended home nursing
and personal care services and who meet a technical definition of “homebound.”
The current 60-day episode of care payment reflects the extended nature of the
benefit.
There may be need, however, for another type of benefit that
is not as extensive or intensive as the current home health benefit. Although
current rules require direct physician supervision of ancillary personnel seeing
Medicare patients, such direct supervision is not practical in some
circumstances. Physicians have said it would be helpful to clinical care
if they could authorize their office nurses or physician assistants to
periodically conduct home visits to check on patients. This benefit, then,
would be limited in scope to infrequent medical monitoring when a patient is not
able to come to the office due to temporary or otherwise acute health conditions
but allows the physician more direct knowledge of health status and functioning
than a service delivered through a separate agency.
Limitations might need to be placed on the benefit, perhaps
by allowing a limited number of visits per beneficiary times per year, by
defining the qualifications of practitioners who might make such home visits,
and by restricting services, perhaps to medical assessment, medical monitoring,
and medication management. Further, the visits might be limited to
follow-up associated with acute exacerbations of chronic conditions, or to
periods when a patient’s treatments have been altered due to a change in health
status.
This benefit is not intended to replace the home health
benefit but rather is intended to be a limited tool by which physicians can
better coordinate care. The benefit needs to be crafted in such a way that it
provides a useful tool for greater clinical care coordination and so that it
does not spawn a new cottage industry. In addition, payment for any such
benefit would need to recognize differential costs and efficiencies between
rural and urban areas. Although the coordinated care and disease management
demonstrations correctly are designed to implement broad-based coordination, it
is likely that information gained in the demonstrations would assist in crafting
specific specifications for this narrow expansion permitted home visits.
Summary
The paper attempts to show that there is a current mismatch
between the chronic care related needs of the majority of Medicare beneficiaries
and the historical structure of the Medicare program that is grounded in a model
of indemnity insurance. Although the more innovative changes in the program
would involve moving toward organizational accountability for caring for
beneficiaries with chronic conditions, through capitated payments -- either for
all covered services or for the services specifically related to care
coordination activities -- such changes will depend upon results of
demonstrations, some of which have recently been initiated. In the meantime, we
recommend incremental changes within the structure of the current program that
would better recognize the needs of beneficiaries with multiple chronic
conditions.
[i] Chronic conditions are defined as conditions that are expected
to last a year or more, limit what one can do and/or require ongoing medical
care. To operationalize this definition, Johns Hopkins University
convened two physician panels to determine which ICD-9 codes met the
definition. SAF and MEPS data were then analyzed with the designations
of conditions. People were generally counted as having a chronic
condition if there were at least two claims in the year for the same
diagnosis, where the diagnosis met the definition. Our claims analysis
tracks chronic illnesses more accurately than it tracks all chronic
conditions because chronic conditions in our definition can include those
that result in activity limitations but do not necessarily require on-going
medical care (defined as two claims in a year).
[ii] The top 15 most common chronic conditions in Medicare are:
hypertension; diseases of the heart (including coronary atherosclerosis and
congestive heart failure, cardiac disrhythmia,among others); disorders of
the lipid metabolism (including hyperlipidemia and pure hypercholesterolemia
among others); eye disorders (including senile nuclear sclerosis, senile
cataract, glaucoma among others); diabetes mellitus; non-traumatic joint
disorders (including osteoarthritis and rheumatoid arthritis among others);
thyroid disorders (including hypothyroidism and thyrotoxicosis among
others); COPD and bronchiectasis (including chronic airway obstruction and
chronic bronchitis among others); diseases of the male genital organs;
diseases of arteries, arterioles, and capillaries (including peripheral
vascular disease, atherosclerosis of extremities or aorta, among others);
senility and organic mental disorders (including Alzheimer’s and senile
dementia among others); spondylosis, intervertebral disc disorders, and
other back problems; affective disorders (including neurotic depression,
major depressive disorder among others); osteoporisis; diseases of the
urinary system; viral infection (chronic); chronic ulcer of the skin; other
connective tissue disease; other nutritional, endocrine, and metabolic
disorders; other endocrine disorders; nutritional deficiencies; anemia,
schizophrenia and related disorders; anxiety, somatoform, dissociative, and
personality disorders; other nervous system disorders; cerebrovascular
disease (including cerebral atherosclerosis among others); asthma.
[iii] Claims analysis based on ICD-9 codes does not count as having a
chronic illness, people with disabilities or activity limitations who do not
require on-going medical care. There are people with disabilities who
do not require on-going medical care as defined in our research parameter of
having two claims in a year for the same chronic condition.
[iv] This number of unique physician visits is 6.7 when people who
died are included and is 4.6 when only outpatient settings among the
age-entitled are included in the analysis.
[v] This analysis includes only age-eligible beneficiaries.
