Autologous Units Positive for ID Markers - Should they be collected and made available for transfusion?
As you recall, an institution informed the e-network that it does not
accept, store or transfuse known infected autologous blood products for
fear of transfusing an infected autologous unit to the wrong patient.
This institution discards all autologous units that are CONFIRMED positive
for HIV, HTLV, HCV or HBV. The institution inquired of the e-network
what others were doing in this regard, because the inquiring institution
is reconsidering its policy of discarding infected autologous units.
While the inquiring institution is worried about storing units known
to be infected with the above viral agents, for fear of transfusing such
a unit to the wrong patient, see this abstract of a report on errors
in transfusion in NY state by Linden JV et al in Transfusion, Oct.,
2000. The inquiring member's institution is also concerned about the Americans
with Disabilities Act (ADA) legislation . The inquiring institution
was looking to the e-network to get a handle on the "community standard".
The above question stimulated considerable discussion, including
a statement from the general counsel for the AABB. I have
organized the replies so that the comments supporting discarding
infected autologous units appear first, and the comments
favoring storing and transfusing such units appear last.
The following replies were submitted in response to the
above:
The following comments support
discarding infected autologous units:
- An institution in Virginia commented
that its policy is to not accept any blood that would be
labeled as biohazard or that would be discarded if the donation
had been an allogeneic one. The institutions legal counsel
(as well as an outside consulting attorney) think that the
question of liability will boil down to a discussion of which
is worse: violating the "rights" of an autologous
donor who is HIV positive or transfusing an HIV positive
unit of autologous blood to the wrong patient. Both attorneys
had a different interpretation than that of the AABB (see
below for the AABB interpretation) with respect to the ADA
and the requirement to collect, store and transfuse HIV infected
autologous donors. These attorneys felt that until the first
case is tried, the "correct" legal answer will
not be known. The Virginia institution's medical executive
committee said that they would rather read a headline that
an HIV positive individual was suing over discrimination,
than read a headline that HIV was transmitted from infected
blood that had been knowingly stored in their hospital inventory.
The greatest challenge that this institution faces is making
sure the blood center cancels the next appointment of the
donor (who's unit will not be used) before they donate another
unit.
- A blood center in Southern California commented
that this is a "can of worms" and it is very unlikely
that consensus will be reached. There is no community standard; "we
all hold dear our own particular viewpoint and will not be
swayed by reason, nor, in my case, law. We are of the school
that does not release, nor draw (with rare exception - in
our case, our local VA.) donors truly positive for HCV, HIV
or HBV (we are not concerned about HTLV). We feel strongly
that the risk to the unsuspecting patient who would get the
wrong unit outweighs the risk to the infected recipient of
harm befalling him/her by getting an extremely safe community
allogeneic unit. Should we allow someone with active TB to
sit in a public place without a mask or do we care that they
might infect a nearby stranger? Why then, should we interpret
the ADA as saying we have to put at risk innocent patients
in order to prevent a theoretical (and vanishingly small)
risk to the patient with a known infectious disease."
- A university-associated public
hospital in Northern California decided to not transfuse
HIV, HBsAg, HCV and HTLV confirmed positive autologous
units. This hospital considered the ADA legislation but
felt that the case before the supreme court (an HIV positive
patient who was denied dental work at the dentist's office)
does not readily apply to the transfusion situation and
does not address the safety of "innocent bystanders" i.e.,
hospital patients who may be at an increased risk if infectious
autologous units are being transfused. Key arguments in
the discussions were a) despite rigorous policies a low
residual risk of erroneous administration of autologous
blood to a nonintended patient seems unavoidable (approx.
1:60,000 - 1:20,000 in several published studies) - importantly,
the risk seems to be less so in the Blood Bank than in
patients areas, for example the OR, b) as a level one trauma
center and teaching hospital, where emergency and massive
transfusions are commonplace, the risk of unit misadministration
may theoretically be even higher and anesthesiologists
and trauma surgeons voiced concern over rare bursting of
pressure transfused units which could shower staff with
blood, c) even though the risk that a misadminstrated autologous
unit is also infectious is lower than the risk of transfusing
a random unit in error, the risk of viral transmission
for specific patients who receive blood during surgery
at a time when infectious autologous units are present
in the OR area may still be higher than the current infectious
risk from allogeneic units, a situation which we think
is not acceptable, d) the benefits of receiving autologous
blood with regard to prevention of infectious disease transmission
is much lower today than in the past and the benefit of
avoiding immunosuppressive effects by transfusing autologous
blood is controversial; moreover in this hospital's patient
population the majority of autologous donor-patients required
allogeneic as well as autologous blood, e) even though
HCV and HTLV positive units pose less of a threat than
HIV or HBsAg positive units, this institution felt from
both a standpoint of transfusion safety and fairness to
autologous donor-patients that none of these units should
be accepted into the hospital. The blood banker reporting
for this institution realizes that this is a controversial
and highly charged topic but he believes "blind" application
of the ADA provisions to the transfusion setting is problematic.
Each institution ought to have the freedom to decide if
they are comfortable with the risk benefit analysis for
transfusing infectious auto units in their facility or
not.
- An institution in North Carolina reports
that it discards confirmed HCV, HIV, and HBV, but not HTLV.
If confirmatory testing is not available before surgery,
the units are released with the surgeon's consent and appropriately
labeled. This institution is also (by coincidence) bringing
this issue to its medical board. About two years ago, the
medical board was informed of the ADA concerns, but it was
elected not to change the policy at that time. The institution
has had some surgeons concerned about the discard policy
for their individual patients. The blood banker reporting
for this institution believes that cogent arguments can be
made on both sides of this issue. While mistranfusion is
on the order of 1:19,000 units, it would be much rarer to
have the unit be autologous and HIV (or HCV, HBV) concurrently.
However, when this does occur, it's a total disaster, analogous
to a plane crash. This has to be weighed against the medical
benefits of autologous blood in these patients, as well as
the legal risks of not making autologous blood available.
- A pathologist in Texas reports that
he believes two very large Houston hospitals have
a policy of keeping no seropositive autologous units in the
blood bank. In this pathologist's own community hospital
(in Richmond, Texas), the institution is currently formulating
its own policy, but the pathologist thinks that his institution
will go along with the 'big guys'. As for the ADA, the pathologist
will probably just ignore the issue until such time that
someone complains and then try to finesse it somehow. The
pathologist believes that it is probably impossible to run
any institution of any type without violating some provision
of the ADA.
- A university medical center in
Southern California, at which both private and public
hospitals are located, has a standardized center wide policy
to accept only autologous blood that is not considered
to be infectious. This center will accept autologous blood
that tests positive for anti-HBcore, ALT, and syphilis
serologies, as such autologous units are unlikely to be
infected. However, all autologous units that are confirmed
positive for HIV, HBV, HCV and HTLV are not accepted.
- An academic hospital in North
Carolina will not accept or store units which are positive
for hepatitis or HIV markers. This hospital will store
autologous units with high ALT.
The following comments favor storing
and transfusing infected autologous units:
- An institution in Denver reported
that while they do not discount the risk of a unit being
transfused to the wrong patient, they are far more concerned
about the incremental risk to all the health care workers
who have direct contact with such an autologous donor. They
will continue to collect a donor who has a positive infectious
disease marker, but it is their policy to notify the donor/patient's
physician after the first unit has been tested and discuss
whether to continue drawing the individual for the requested
number of units. The patient's physician has the responsibility
to notify the operating room team in advance that they will
be handling units ( and the patient, for that matter) which
are positive for an infectious disease marker. This institution
feels that this is prudent despite the expectation that everyone
will use standard precautions, especially since the units
are labeled in a manner that would cause concern to those
handling them.
- At a cancer institute in Southern
California, they accept and transfuse the autologous
units described because of the ADA legislation. Prior to
the ADA legislation, they did not accept such units. Their
decision was in part based on the information provided
by the AABB in Association Bulletin #98-5. (You must be an AABB member to access this page). To help
minimize the potential for mistransfusion errors, they
also implemented a policy for these units requiring that
they be issued only for immediate transfusion, and not
allow the units to be stored in the satellite refrigerator
in surgery.
- Another hospital in Southern
California reported that it accepts all autologous
donations, regardless of test results (all units must be
tested to be received -- the institution does not accept "untested" units)
but the unit will be acceptable (for that recipient only)
regardless of the results of confirmatory testing, for
any test. Physician notification of abnormal test results
must occur (in accordance with AABB Standards). Additionally,
for units that are confirmed positive for anti-HIV, HBsAg
and HIV p24 antigen, the patient's physician must provide
documentation of notification / request to use the product
(in accordance with FDA memoranda 3/15/89 and 8/8/95).
- A large blood center in the
Southwestern U.S. reported that since they are at the
collection/distribution end they don't defer autologous
donors who are known to be positive for viral markers.
They follow special procedures during collection from high
risk donors (defined as those with confirmed positive HBsAg,
anti-HIV and/or HIV p24 Ag). Donors and their physicians
are notified of positive test results. Collection Centers
maintain letters from hospitals verifying which units with
positive viral marker(s) will or will not be accepted.
.FDA requirements are included in 2 memoranda (3/15/89
and 2/12/90). The blood banker reporting on this center's
experience says that the majority of hospitals accept most
positive units including HIV & HBsAg units. It has
been suggested that autologous blood transfusion would
be beneficial for patients with HIV infection, since they
would avoid the immunomodulatory effect of allogeneic (WBC)
blood and possible HIV and CMV viral activation (VATS study).
Recent study by the same group found no evidence of HIV,
CMV, or cytokine activation following allogeneic blood
transfusion in patients with advanced HIV infection (JAMA
2001; 285:1592-1601).
- A large south central U.S. blood
center follows the policy of their individual hospitals.
This center is often asked to provide informational materials
on this issue, but they try to take a neutral position.
There has always had a mixed practice among their hospitals,
some will take positive units and others never do. But
in the last couple of years it seems that more hospitals
are willing to take positive autologous units, including
confirmed
positive HIV autologous units. They say it is because of
the ADA ruling and discussions within their own risk management
department, and also because of shortages within the community
blood supply. They argue, how can you tell a patient he/she
can't use his/her autologous unit when elective surgeries
are being cancelled/postponed for lack of blood?
- An institution in Central California accepts,
stores and transfuses infected autologous units. The process
starts earlier with their donor center, which is also located
in Central California. They notify the ordering physician
of any positive markers and ask if he will accept the units.
Some physicians refuse, but the majority ok the continuation
of the donations. The infected units arrive tagged from the
donor center in a plastic bag. This helps to protect the
refrigerator in the event that there is a leak (however unlikely
the possibility). This hospital reports that they have never
transfused an autologous unit to the wrong person. The additional
tag and baggy flag the unit, so that it is handled with care.
- A Medical Director of a blood
center in Northern California reported that almost
all of the hospitals that her center supplies (San Francisco
Bay area) will accept autologous units from patients with
such viral infections. There was an initial move away from
accepting these units but after the passage of the ADA
legislation most facilities reconsidered their decisions.
Even those hospitals who retain a non-acceptance policy
end up taking the unit(s) if it has already been drawn.
It seems important to put the risk in perspective. According
to this medical director, if you give blood from a donor
who is group A and the patient is group O the patient might
have an immediate fatal transfusion reaction. No one would
even think of suggesting that we should not put group A
units in our blood bank refrigerators for fear that there
might be a clerical error. In view of the immune effects
of allogeneic transfusion one might argue that those with
significant viral infections who are well enough to donate
their own blood in advance of elective surgery should be
encouraged to do so. It was suggested that the e-network
might be interested in reading a discussion of the two
sides of this issue in the AABB Monograph "Component
Selection: Polemics and Politics" from 1996. One
chapter, authored by Dr. Cherie Evans, was entitled "HIV
Infected Patients in Autologous Blood Programs' (pro)
and the other chapter, authored by Dr. S. Breanndan Moore,
was entitled "Should Patients Infected with HIV or
Hepatitis Donate Autologous Blood" (con).
- A large blood supplier (which
ships more blood than any other collection center in California) reported
that they release autologous units that are positive for
HIV, HBV, HCV, and HTLV to transfusion services. For HIV
and HBV, the transfusion service must send written confirmation
that they wish to have the unit shipped to them before
they will release the unit for shipment. Units with HCV
and/or HTLV repeat reactivity or positively are shipped
automatically to the transfusion services (with the exception
of a very few transfusion services who have indicated that
they do not want certain autologous units with either repeat
reactive or positive markers shipped to them).
(Editor's NOTE: At my medical complex are three separate
transfusion services (LAC+USC Medical Center, USC Kenneth
Norris Cancer Hospital and USC University Hospital) all of
which refuse to accept infected autologous units from
this supplier, for reasons described in the first set
of replies).
- And finally, a word from the
AABB: "In relation to a recent inquiry to the
CBBS e-network regarding institutions' practices for accepting
HIV positive units, individuals are encouraged to review
an Association Bulletin published by the American Association
of Blood Banks entitled 'The ADA, HIV and Autologous
Blood Donation.' As described in this bulletin, in
1998, the Supreme Court ruled that an individual who is
HIV positive has a protected disability under the Americans
with Disabilities Act (ADA). Although no court has yet
addressed the specific issue of blood donations from an
HIV positive individual, it is likely that a court would
hold that an institution that offers autologous blood donation
and transfusion services cannot deny such services to an
HIV positive individual under the ADA. It is also likely
that courts would apply similar reasoning to cases involving
patients diagnosed with other infectious diseases, such
as HCV. The AABB Association Bulletin can be accessed on
www.aabb.org, in the Members Section, under Resource Center > Publications > Association Bulletins > Association Bulletin 98-5.
If individuals have questions about this Association Bulletin
or this issue, please contact me by e-mail or
phone (301/215-6554). Theresa L. Wiegmann, General Counsel,
American Association of Blood Banks."

- At my institution, we collect,
process and transfuse autologous units regardless of their
positive test results. We have collected autologous units
from donors known to be confirmed positive for HIV. We test
autologous units only if they are going to be frozen at the
local blood center or shipped outside of our facility. Autologous
units that will be used at our facility are not tested except
for ABO/Rh and antibody screen.
We segregate autologous units
as much as possible. During processing and labeling,
the units are kept on separate shelves. After the units
are labeled and retyped, they are kept in a separate section
of one refrigerator. The units are kept in this refrigerator
until they are issued to the floor for transfusion.
Units that are not tested for
viral markers are labeled with a biohazard sticker and
put in a pink zip lock bag.

- Our facility does not accept autologous
positive HIV and HBV blood back into the institution. We
are worried about the Americans with Disabilities Act legislation,
too. Could the transfusion of HIV, etc. positive autologous
blood be approached medically as a less than optimal product
for the patient to receive back into their body due to viral
loads? There is the antecdotal story of the HIV-positive
patient being refused autologous donation, getting an allogeneic
transfusion and developing Hepatitis C from it. I'm sure
there are many ethical issues involved and would love some
definitive guidlines.

- A California colleague is interested in an update about how other institutions currently handle autologous units that test 'positive' for infectious disease markers; specifically if there has been any increase in institutions not collecting or storing such units. At present, the inquiring colleague's institution attempts to dissuade autologous donations from individuals known to be infected with a transmissible viral infection, giving the reasons of hazard to unintended transfusion recipients, etc. While the vast majority of known positive autologous donors agree to not have their units collected or used, a small minority vociferously demands to have their autologous units available, regardless of risk to others."
