Chairman Grassley, Senator Breaux, distinguished Committee members, thank you for
inviting us to discuss our efforts to improve home health care quality through better
patient assessment and measurement of the outcomes of care. We are required by law to
monitor the quality of home health care with a "standardized,
reproducible assessment instrument." To improve
care and comply with the law, we will be using the Outcome and Assessment Information Set
OASIS helps home health agencies determine what patients need, develop the right plan
for their care, assess that care over the course of treatment, and learn how to improve
the quality of that care. It incorporates all the information about patients' health and functional status, health service use,
living conditions, and social support that are needed to support all the home health
agencies' responsibilities. In addition to
monitoring quality, OASIS also is essential for accurate payment under the new home health
prospective payment system that the law requires us to use beginning October 1, 2000. We
will be requiring use of OASIS by home health agencies as a Condition of Participation in
the Medicare and Medicaid programs this year.
The important benefits of OASIS must be implemented in a way that protects personal
privacy. At HCFA, we have an excellent historical record of safeguarding sensitive
beneficiary information. Our agency provides greater protection for personal medical
information than generally exists in the private sector, and we are actively participating
in the Administration's inter-agency process to make Secretary Shalala's recommendations
for medical privacy work on the operational level.
In recent months, we have come to realize that stronger privacy protections must be
built into the structure of our new operations. President Clinton and Vice President Gore
have both spoken about the paramount importance they attach to medical records privacy.
This is why the Administration has been a consistent advocate for effective medical
records privacy legislation. I am pleased to announce some new steps we are taking to
assure the privacy of patients while maintaining the legitimate focus of the OASIS
program, such as:
- Careful drafting of a notice that Medicare and Medicaid patients will receive. The
notice will explain why OASIS data is collected, and inform patients of their right to see
and request corrections of the data.
- Limitations on "routine uses" of data under the Privacy Act, so that personally
identifiable data will only be used where statistical information is not sufficient. Among
other changes, personally identifiable data will no longer go to accrediting organizations
such as the Joint Commission for Accreditation of Health Organizations.
- Major changes in the treatment of private-pay patients under OASIS. We have decided that
information on non-Medicare and non-Medicaid patients will not be transmitted to
the States or the agency in personally identifiable form.
- After careful attention to each question in OASIS, virtually all questions were retained
on grounds of assuring quality of care and appropriate reimbursement. We did identify a
sensitive question on patient financial factors that we consider less critical to
achieving program goals, and this information will not be reported to HCFA or the States.
- Acceleration of efforts to encrypt data during transmission, to provide yet another
level of protection. We expect to complete these efforts within a year.
We are also making special efforts to help home health agencies learn how to use this
valuable tool. We have learned through a demonstration of OASIS that, once home health
care providers learn how to use OASIS, it actually slightly reduces the total time it
takes to conduct a thorough patient assessment. Home health care professionals who have
used OASIS in the demonstration agree that it takes no longer to use than their previous
assessment methods. Because OASIS is structured in a checklist format, home health staff
using it spend less of the total evaluation time writing out a narrative of their
assessment findings and more time with the patient. A chart comparing average patient
assessment times with and without OASIS is attached to my testimony.
More than 8,000 of the approximately 9,500 home health agencies participating in
Medicare across the country have now received official OASIS training. Efforts to help
providers through the OASIS learning curve include:
- a satellite broadcast training session on August 20, 1998 to sites across the country
reaching approximately 30,000 home health care professionals (tapes of this session are
- numerous presentations at industry trade association meetings;
- distribution of a free, detailed manual on how to collect OASIS data, use the software,
and report the data;
- manuals, software, updates, and other additional assistance that can be downloaded from
the Internet at cms.hhs.gov/medicare/hsqb/oasis/oasishmp.htm;
- answers to questions on installing OASIS software via a toll-free telephone line at
1-877-201-4721 and via E-mail haven_help"ifmc.org;
- establishing OASIS Educational Coordinators in all States;
- a week long conference last September to teach State personnel about OASIS; and
- a "train the trainer" program last October for all State OASIS Educational
Coordinators to provide materials and detailed information on how to teach home health
care professionals in their State how to use OASIS.
Home health patients are among the most vulnerable Medicare and Medicaid beneficiaries.
They tend to have more health problems, and the fact that care is delivered in the home
makes monitoring the quality of that care more challenging. The Omnibus Budget
Reconciliation Act of 1987 mandated that Medicare monitor the quality of home health care
and services with a "standardized, reproducible"assessment instrument. The following year we
contracted with University of Colorado researchers and clinicians to develop such an
instrument. We have been working ever since to refine and validate what has become OASIS.
OASIS has been used by 162 home health agencies in various demonstration projects
around the country. It has been tested in a national Outcome-Based Quality Improvement
demonstration involving 50 home health agencies of all sizes, and in a single-State
demonstration project involving 22 agencies. OASIS questions also have been used in the
national Medicare home health prospective payment demonstration, which includes 90
agencies in five States.
OASIS provides a standardized format for the patient assessments that home health
agencies have been doing all along. It does not require additional effort for agencies
that have been conducting the thorough patient assessments that are needed in order to
provide appropriate care. OASIS incorporates only information needed to support concrete
indicators of patient need and quality of care.
The 79 data elements in OASIS were developed by clinicians and are valid, reliable, and
risk adjusted, taking into account all characteristics of patient populations. This
ensures that assessments done by different health care professionals with OASIS
consistently yield the same results. It also ensures that quality measurement takes into
account whether agencies are caring for sicker patients and therefore might have what
otherwise would appear to be poorer care or outcomes.
OASIS is supported by the American Academy of Home Care Physicians, the National
Alliance for the Mentally Ill, and many home health care providers who are voluntarily
using OASIS because of its unprecedented value in promoting high quality care and
comprehensive, accurate, clinical record-keeping. Home health care professionals using
OASIS report that it is helping them to be more focused on the needs of individual
patients, and to provide better care in fewer visits and with fewer subsequent
We first published a proposed rule for requiring use of OASIS by all home health
agencies participating in the Medicare and Medicaid program in the Federal Register
on March 10, 1997. Many comments on the proposed regulation suggested adding additional
questions. However, to keep OASIS at a reasonable length, we instead will allow agencies
flexibility to expand OASIS for their own patient population. For example, an agency that
provides a larger share of mental health services can add extra questions related to
mental health if it so chooses; however, these data will not be transmitted.
On January 25, 1999, we published a final regulation requiring use of OASIS and an
interim final rule requiring that home health agencies encode and transmit the data to us.
We had planned for home health agencies to begin mandatory reporting of OASIS data on
April 26, 1999. However, on April 7 we announced that we would postpone the requirement in
order to conduct a thorough evaluation of privacy concerns and to complete the review of
OASIS pursuant to the Paperwork Reduction Act of 1995. Once these concerns are addressed,
we expect to publish a new date for the start of mandatory collection and will report it
in the Federal Register.
Once reporting begins, home health agencies will transmit computerized, coded OASIS
data to State survey agencies using a private network with a direct phone connection. The
State will compile the data and send it to the Health Care Financing Administration. OASIS
system users must enter an ID and password at three different checkpoints before access is
permitted. And, the data transmitted to the States and to HCFA is fully protected under
the federal Privacy Act. The Privacy Act has been effective in ensuring confidentiality of
We will develop a performance report for each home health agency based on its OASIS
reports, including a comparison of its performance to the State and national average.
These performance reports will allow home health agencies to identify their own weaknesses
and improve the quality of care they provide. They also will allow us to compare the
quality of care among agencies and thereby increase scrutiny for those that need more
oversight and assistance in improving quality. Eventually, we will share these agency
performance reports with the public so consumers can make informed choices among home
health agencies based on the quality of care they provide. Examples of the information
these reports will provide is attached to my testimony.
Data that can identify individual Medicare and Medicaid patients are critical to
ensuring that we pay accurately for care and that we can monitor the quality of care. It
allows evaluators to assess whether a home health patient's later admission to a hospital or nursing home might
be related to gaps or problems with the care provided by the home health agency and
identify potential areas for improvement. It is also essential for ensuring accurate
payment under the prospective payment system. In particular, it links the OASIS data to
actual claims data in order to create the proper weightings for reimbursement.
As I stated earlier, all information that could be used to identify private pay
patients will be removed by the home health agencies before OASIS data is reported to HCFA
and the State.
OASIS and Prospective Payment
OASIS data are critical to development, implementation, and accurate payment under the
home health prospective payment system that Congress has required we implement in October
2000. We need to collect OASIS data as soon as possible in order to develop prospective
payment rates and estimate their impact based on comprehensive national data. Doing so
based on the limited OASIS research data available to us now could jeopardize our ability
to pay accurately and to understand in advance how different types of agencies across the
country will be affected.
The comprehensive information in OASIS is necessary to accurately determine the
appropriate amount of care, and therefore the appropriate amount of payment for that care.
This is particularly important in the home health environment, which is complicated by
confounding factors such as patient behavior. Patient diagnosis alone, which is the basis
for inpatient hospital prospective payment, predicts less than 10 percent of home health
patients' need for service.
Using OASIS to both determine accurate payment and assess quality helps to minimize the
burden on home health agencies. It also helps fight fraud and abuse, which has been a
substantial problem in home health care, because it balances incentives. While prospective
payment creates an incentive to "upcode"and say patients are sicker in order to receive
higher payment, doing so with OASIS would result in poor quality indicators. That could
trigger an investigation, as well as result in a competitive disadvantage when home health
agency profiles based on OASIS data are eventually shared with the public.
Using OASIS to monitor quality is even more essential under a prospective payment
system. As mentioned above, prospective payment creates highly effective incentives to
provide care efficiently, but those incentives must not be allowed to reduce appropriate
care. OASIS will help providers accurately assess what the proper level of care is, and it
will help us monitor that care to ensure that patients are getting all the care they need.
OASIS represents a significant advance in home health care. It is proven in rigorous
testing to help improve the quality of patient care and the outcomes of that care. It
allows home health care professionals to spend more time with patients and less time
writing up assessments. It will help ensure accurate payment under the new prospective
payment system. It will help ensure that beneficiaries receive high quality care. And it
will help protect taxpayer dollars and the integrity of the Medicare and Medicaid
programs. We are taking extra precautions, beyond our already stringent privacy
protections for Medicare and Medicaid data, to ensure the confidentiality of OASIS
information, and we are communicating these precautions to all (Medicare, Medicaid, and
private pay) patients before they receive home health care. In addition, we are working to
help home health care professionals learn how to use this important new clinical advance.
I thank you for holding this hearing, and I am happy to answer your questions.
