THE 2005 NATIONWIDE BLOOD COLLECTION AND UTILIZATION SURVEY REPORT
1. Executive Summary
The Department of Health
and Human Services (DHHS)
and AABB conducted the
fourth nationwide survey of
blood services and related activities in July 2005. (Earlier
surveys were conducted in
2002, 2000, and 1998.) The
purpose of the survey (a
12-page questionnaire) was to
assess the amount of blood
collected and transfused in
the United States (US) in 2004
and to provide data to assist
the DHHS in validating its
Blood Availability and Safety
Information System. The facilities surveyed included all

THE 2005 NATIONWIDE BLOOD COLLECTION AND UTILIZATION SURVEY REPORT
The composition of the source
of the blood supply in 2004
was different from that of previous years. In 2001, traditional allogeneic collections
were responsible for the high
number of units collected. In
2004, these numbers remained high, but because of
the increased use of red cell
apheresis technology in the
face of reduced (and, in the
case of autologous and directed donations, significantly
reduced) traditional blood
collections. Red cell apheresis
collections increased 202%
over 2001, yielding approximately 824,000 RBC units.

Executive Summary
THE 2005 NATIONWIDE BLOOD COLLECTION AND UTILIZATION SURVEY REPORT
2. Key Findings
The results of The 2005 Nationwide Blood Collection
and Utilization Survey
(NBCUS) provide an update
of United States (US) blood
services and related activities
assessed by the three previous
nationwide surveys conducted in 2002, 2000, and
1998. Notable findings from
the 2005 NBCUS and comparisons with the 2002 survey
results were as follows:
• Allogeneic collections remained statistically the
same at 14.8 million units.
• Total WB/RBC transfusions
remained statistically the
same at 14.2 million units.
• Autologous collections declined significantly by 26%
to 458,000 units.
• Red blood cell apheresis
collections increased 202%
for a total of 824,000 units.
• The total number of all
components transfused in
2004 was 29,038,000.
• The total number of transfused units that were irradiated increased by 15.8%
while those that were
leukocyte-reduced increased by 2.7%.
• Transfusion of prestorage
leukocyte-reduced units increased by 7.9%, while the
transfusion of poststorage
leukocyte-reduced units decreased by 45.3%.
• There was a significant
(54%) decline in HPC-M
transplant procedures performed.
• There was a 42.9% decrease in the number of
outdated whole blood (WB)
and red blood cell (RBC)
units.
• The transfusion of wholeblood-derived platelet concentrates continued to decline (–41.2%), while the
use of apheresis platelets
increased by 10%. Overall,
transfusion of platelets remained essentially the same
at 9.9 million units.
• Almost all blood centers
(99.2%) and hospitals
(89.6%) have emergency
preparedness plans for
blood services.
• A total of 135 hospitals reported the cancellation of
elective surgery on one or
more days because of
blood inventory shortages.
This affected 546 patients,

significantly fewer than in
2001.
The mean age of RBC units
at transfusion was 17 days.
The mean age of wholeblood-derived platelet units
was 3.16 days at transfusion; for an apheresis
platelet unit, the mean was
3.08 days.
The average cost of RBC
units increased by 30.8%.
A statistically significant increase in the cost since
2001 was measured for all
four components assessed.
The WB/RBC collection
rate per thousand US donor
population was 85.6 units
in 2004, compared to 88.0
in 2001. The WB/RBC
transfusion rate remained
the same at 49.6 units per
thousand US population
overall.
The margin between
test-negative allogeneic
WB/RBC units collected
and those transfused in the
US in 2004 was 648,000
units, compared to approximately 920,000 in 2001.

THE 2005 NATIONWIDE BLOOD COLLECTION AND UTILIZATION SURVEY REPORT
3. Introduction and Methods
This report presents the results
of the fourth Nationwide
Blood Collection and Utilization Survey (NBCUS), conducted in 2005. The survey
was funded by the Department of Health and Human
Services and conducted by
AABB (Bethesda, MD). Previous surveys were conducted
in 1998, 2000, and 2002 by
the National Blood Data Resource Center, a whollyowned subsidiary of AABB.
Objectives
The objectives of the survey
were to generate national estimates for blood services activities in the United States (US)
in 2004; to provide comparisons with previous measurements; to provide data to validate a real-time national
blood supply and utilization
monitoring system; and to
characterize business practices in the blood collection,
transfusion medicine, and cellular therapy community.
The survey instrument was
designed to capture quantitative data regarding blood col-
lection, processing, transfusion, and final disposition, as
well as other information describing current policies and
practices, and the adoption of
new technologies by the
blood community.
Park, NC). Validation of survey data was achieved by
comparison with 2001 survey
data and by direct contact
with individual respondents as
necessary.
Sampling Frame
Data Collection
The 12-page questionnaire,
cover letter, and postage-paid
return envelope were mailed
in July 2005 to the 2,976
facilities in the sample described below. Survey packets
were addressed to the director
of either the blood center or
the hospital blood bank or
transfusion service. A second
mailing of the survey questionnaire was sent to 2,492
nonresponders six weeks afterwards. Those facilities that
did not respond by the initial
September deadline were
contacted by e-mail, telephone, or both. Data collection concluded on October
31, 2005.
The sampling frame for the
2005 NBCUS was compiled
from two data sources. The
first source was the AABB database, which is a list of all
non-hospital-based blood collecting facilities in the 50
states. This list also contains
hospitals that are members of
AABB. The second source is
the American Hospital Association (AHA) database.
To construct the sampling
frame from the AHA database,
several criteria were used.
Only those hospitals providing general medical and surgical service, children’s general
medical and surgical service,
and obstetrics and gynecology
services were considered eliData coding, keying, and veri- gible population members.

hospitals responded to the
2002 AHA hospital survey. To
ensure comparability with
previous surveys of domestic
institutions, the following
types of treatment facilities
were excluded from the AHA
sampling frame: military and
federal facilities, such as Department of Justice facilities,
Indian Health Service facilities, and non-US facilities.
Veterans Affairs treatment facilities were included in the
sampling frame. Finally, hospitals reporting fewer than

Sample Selection
The NBCUS sampling frame
consisted of all the blood centers on the AABB list and all
eligible hospitals on the AABB
list. This initial list of treatment
facilities was supplemented
with hospitals from the AHA
database to ensure a total
sample of 3,000 facilities. The
AHA hospital database was
stratified into six categories
according to annual inpatient
surgical volume. The strata
are defined as follows: 100999 surgeries, 1,000-1,399

Useful information was captured using the control system. However, because of the
complex issue of different
types of treatment facilities
(including health systems, individual hospitals, satellite facilities, and affiliated hospitals) that report together,
information necessary to adjust the weights with absolute
accuracy could not be captured. Additional information
describing the relationship between sample members and
those for whom they report, as
well as reporting practices,
will be essential to accounting
for these complex issues. In
other words, stricter definitions of the eligible population
and reporting requirements
are needed for future surveys.

4. Blood Collected and Processed
in the United States
Total Collections
The total supply of blood collected in the United States in
2004 was 15,288,000 units
before laboratory testing
(Table 4-1). Blood centers
collected 14,305,000 units, or
93.6% of the total. The balance of 983,000 units (6.4%)
was collected by hospitals.
The total supply in 2004 was
virtually unchanged (–0.2%).
However, the composition of
the supply in 2004 was different than that of 2001. While
traditional allogeneic collections were responsible for the
high number of units collected in 2001, in 2004 these
high numbers were maintained by the increased use of
red cell apheresis technology
in the face of reduced (and, in
the case of autologous and directed donations, significantly
reduced) traditional blood
collections. On a positive
note, the gain seen in blood
donation activity following
the terrorist attacks of September 11, 2001, has not been
lost in the subsequent years.

from the 2001 volume (Table
4-3). Platelets were prepared
from 30.3% of all allogeneic
WB collected, essentially unchanged from 2001. Blood
centers processed 3,930,000
units (93.5%), while hospitals
produced 272,000 (6.5%).
An estimated 1,164,000
apheresis platelet procedures
were completed, yielding
1,527,000 platelet doses. This
volume indicates a split rate
of 31.2% overall. For comparison with production of WBderived platelets, it is assumed
that the number of platelets in
each apheresis collection is
equivalent to six units of
platelet concentrates, yielding
the equivalent of 9,161,000
platelet concentrate units. This
was statistically unchanged in
comparison with 2001. Blood

2004, 261 (16.3%) hospitals
answered the question, compared with 179 (15.7%) in
2001. The responses totaled
297,000 units ordered, as
compared with 350,000

was then calculated as a percentage of the total units

outdated by hospitals.
The national estimate for all
whole blood and blood component units outdated by
blood centers and hospitals in
2004 was 1,551,000 units.

7. Current Issues in Blood Collection and
Screening
Screening Test Losses
The overall number of donated whole blood units with
positive results on infectious
disease screening tests was
270,000, or 1.8% of allogeneic collections, including
directed donations. The number of units collected by
blood centers and discarded
for this reason was 255,000
(1.9%) (n=138 blood centers
reporting). Among hospitals,
screening test loss was 1.8%
of donations or 15,000 units
(n=258). Screening test loss
was lower in hospitals than
reported in 2001, when the
test loss totaled 2.5% of
donations.
perienced testing losses significantly lower than the mean
in 2004. The proportions of
units lost per individual
screening test were not assessed by the 2005 NBCUS.
Therapeutic Phlebotomy
Blood centers reported a total
of 28,000 procedures performed at 33 centers. The
number of procedures per
center ranged from 31 to
3,685, with a median of 471
procedures. Hospital data
were weighted to achieve a
national estimate of 112,000.
The median for hospitals was
41 procedures, with a range
of 1 to 1,839. Together, hospitals and blood centers nationwide are estimated to have
performed 140,000 therapeutic phlebotomy procedures in
2004. This is not significantly
different from the previous
survey findings. The larger the
surgical volume of the hospital, the more likely the hospital was to offer this service,
with the most procedures being performed at hospitals
with 8,000 or more surgeries
per year.
Therapeutic phlebotomy procedures are performed for the
benefit of the donor as a patient rather than for blood collection purposes. In August
2001, the US Food and Drug
Administration (FDA) approved the use of blood
collected from hereditary
hemachromatosis patients for
transfusion. The FDA has allowed this use provided that

8. Current Issues in Blood Transfusion
Blood Inventory
Shortages
The current survey, as well as
previous versions, asked hospitals to indicate the number
of days in the past year that
elective surgery was postponed because of blood inventory shortages, as well as
the number of days that they
were unable to meet other
blood requests. The results are
based on actual (unweighted)
responses.
A total of 135 hospitals (8.4%)
reported that elective surgery
was postponed on one or
more days in 2004 because of
blood inventory shortages. Table 8-1 provides a character-
ization of cancellation reports
in 2004 in comparison with
previous survey years. The
percentage of responding hospitals reporting any shortage
was a statistically significant
decrease from the 2001 data
(p<0.0001), but comparable
to the percentages from 1997
and 1999 data. The range (1
to 39) of days postponed was
narrower in 2004 than in the
recent surveys, but the mean
number of days for all hospitals responding was 3.39, noticeably higher than in years
past. This suggests that while
shortages were less frequent,
when they did occur they
were more acute. There were
no significant differences in
the mean number of days of
postponement among hospitals when grouped by surgical
volume or by region of the
country.
Hospitals indicated separately
that the total number of surgical procedures that were postponed was 546 (n=110) compared with 952 in 2001
(p=0.026). This is a decrease
of 42.6%. The number of surgeries postponed varied significantly between hospitals by
surgical volume (p=0.003).
Hospitals that performed
1,400 to 2,399 surgeries per
year appeared to have the
greatest proportion of surgeries postponed among those
reporting.

Hospitals also indicated the
number of days in which
nonsurgical blood requests
were not met. Of responding
hospitals, 16.0% (257/1604)
experienced at least one day
in which nonsurgical blood
needs could not be met vs
18.9% (202/1,066) in 2001
and 16.2% (273/1,588) in
1999. The total number of
days reported was 4,953 and
the range was 1 to 366 (2004
was a leap year). There is a
significant difference between
the mean number of days of
unmet nonsurgical needs for
all respondents between 2001
(2.1) and 2004 (19.27)
(p<0.001). Eight hospitals reported 365 or 366 days in
which nonsurgical blood requests were not met in 2004,
whereas only one hospital reported an entire year of unmet
need in 2001. This most likely
accounted for the large increase in the mean between
2001 and 2004. The hospitals
reporting this condition were
evenly distributed throughout
the country, and only one of
these hospitals had reported
any days of unmet need in
2001.

9. Component Costs
Hospitals were requested to
report the minimum, maximum, and average costs paid
per unit in 2004 for each of
four specific components.
These cost data were not imputed or weighted. The mean
of the reported results for each
variable is presented in Table
9-1 and compared with the
2001 value. Table 9-2 displays the average cost of each
component by region of the
country and provides a statistical comparison with the national average. Average component costs are stratified by
hospital surgical volume in
Table 9-3.
Red Blood Cells
The mean of the average
amount paid nationally for a
unit of red blood cells (RBCs)
that was O positive, leukocytereduced, not irradiated, and
not cytomegalovirus negative,
was $201.07 (Table 9-1). This
was higher than the average
in 2001 ($153.68); the difference was statistically significant (p<0.0001). The values
reported by hospitals for this
component ranged from a
minimum of $5.00 to a maximum of $595.00. When
analyzed by United States
Public Health Service
(USPHS) region, the mean of
the average value reported
was significantly different
from the national average in
every region except III, VIII,
and X (Table 9-2). The average cost was significantly
higher than the national mean
in the Northeastern and
Southwestern states (I, II, and
IX). Significantly lower means
were found in the Southeastern and Central states (IV, V,
VI, and VII; p<0.0001). When
analyzed by surgical volume,
the only stratum that differed
statistically from the overall
mean was that of hospitals
with 1,400-2,399 annual inpatient surgeries, with a mean
of $205.45 (p=0.0461) (Table
9-3).
Fresh Frozen Plasma
The mean cost of a unit of
fresh frozen plasma (FFP),
type AB, with a volume of
approximately 250 mL, averaged $56.29 nationally (Table
9-1). The higher cost than the
2001 mean of $52.37 was
statistically significant
(p<0.0001). The values reported by hospitals for this
component ranged from a
minimum of $20.00 to a maximum of $259.77. When analyzed by USPHS region, the
mean of the average values
reported was significantly
higher in the regions including New York, and the Mountain and Western states (II,
VIII, IX, and X). The means reported by regions IV and VII
(which include Southeastern
and Midwestern states) were
significantly lower than the
national mean (Table 9-2).
Hospitals in the largest surgical volume stratum (≥8,000)
reported a mean cost for FFP
that was significantly less than
the overall mean, $52.19
(p=0.0080) (Table 9-3). Not
surprisingly, smaller facilities
(100-999 surgeries) reported
significantly higher FFP costs
(p=0.0257).

in 2004 (Table 9-1). This increase of 16.0% over the
2001 cost was statistically significant (p<0.0001). The reported range varied from
$23.00 to $396.95. The
higher mean costs for this
component in the New England and Northwestern
states—regions I and
X—(compared with the national mean) were statistically
significant (Table 9-2). The
hospitals in the smallest surgi-
cal stratum (100-999) again
reported significantly higher
costs (p=0.0263).
Apheresis Platelets
The mean cost of a unit of
leukocyte-reduced platelets
collected by apheresis (3-4 ×
1011 platelets) was $510.05 in
2004 in comparison with
$475.48 in 2001, a statistically significant increase of
7.3% (p<0.0001). Reported
values ranged from $114.00
to $1,200.00. The mean cost
was lower in the Southeastern
and Midwestern states (regions IV, V, and VII). Regions
that were significantly higher
than the mean were II, VI,
VIII, IX, and X (which include
New York and New Jersey as
well as the Mountain, South
Central, and Western states as
listed in Table 3-6). When
stratified by surgical volume,
there were no statistically significant differences in the cost
of this component.
Reimbursement
The Centers for Medicare and
Medicaid Services (CMS) hospital outpatient prospective
payment system (OPPS) reimbursement rates for the four
components assessed are reported in Table 9-4. While
costs for components increased between 2001 and
2004, outpatient reimbursement decreased for all components during the same period. The reimbursement rate

10. Cellular Therapy Products
Because of ongoing interest in
hematopoietic transplantation
and novel cellular therapies,
the 2005 NBCUS captured
data on collection, processing, and infusion of five types
of cellular therapy products:
hematopoietic progenitor cells
collected by apheresis (HPC-A),
HPCs derived from marrow
(HPC-M), HPCs from cord
blood (HPC-C), lymphocytes,
and cell products generated in
culture.
The survey questions were
nearly identical to those in
previous surveys so that comparisons could be made and
trends identified. This was the
first year that public cord
blood banks were included in
addition to blood centers and
hospitals. The majority of independent cord blood banks
are private in that the HPC-C
units are collected, stored,
and processed at the private
expense—and for the future
potential use—of a family
member. However, there are
some public or allogeneic
cord blood banks and attempts were made to include
them in the survey. Nine cord
blood banks, all AABB mem-

some of which have had
mixed public and private
activity—in the survey. But
overall HPC-C collections
were lower than in the previous survey, a consequence of
a large decrease in allogeneic
collections by blood centers,
with the aforementioned large
blood center no longer participating in cellular therapy activities. It is also possible that
there is underreporting of hospital HPC-C collections when
the collection takes place in
the obstetrics ward and is not
reported to the hospital blood
bank. Increased collections
were also noted for both
autologous and allogeneic
lymphocytes and allogeneic
cells generated in culture.
HPC-M collections continued
the declining trend—perhaps
because HPC-A collection is
so much easier on the donor.

Processing activity for cellular
therapy products is displayed
in Table 10-3 and Figure

the last survey, with 32,125

of cord blood banks contributed much to the increase in

common in hospitals than in
blood centers. The number of
hospitals collecting
autologous HPC-A products
exceeds the number collecting allogeneic HPC-A products (95 vs 60), both reduced
from the previous survey.
Fewer blood centers as well
as hospitals reported collecting cord blood in 2004 than
in 2001. This may be in response to the number of cord
blood banks that have entered the market and the exit
of a major blood center from
the cellular therapies market.

The reporting in this survey
may better reflect the areas of
responsibility, with the hospital responsible for the HPC-C
collection (possibly under the
blood center’s protocol) and
the blood center or cord
blood bank responsible for
processing and storage.
Of hospitals reporting collection activity for cellular therapy products, those with
higher surgical volumes gen-
erally were more likely to
have the higher levels of activity, as seen in previous surveys (Figure 10-4 and Table

11. Historical Perspectives
The 2005 NBCUS has allowed for the extension of the
findings of previous nationwide surveys conducted by
the National Blood Data Resource Center in 2002, 2000,
and 1998, and earlier assessments conducted by the Center for Blood Research and the
National Heart, Lung, and
Blood Institute.

2004, autologous collections
comprised only 0.46 million
units, or 3.0% of total collections, the lowest amount that
has been measured by contemporary surveys.

Blood Supply Adequacy
The available supply of both
WB/RBCs and non-RBC components was sufficient to meet
overall transfusion demands
in 2004. Yet, despite the increase in collections achieved
since 1997, there is cause for
concern regarding the adequacy of the United States
(US) blood supply, both currently and in the future.
The shrinking margin between
allogeneic WB/RBC supply
and demand depicted in Figure 11-2 is one reason for
concern. In 1989, allogeneic
collections totaled 13.6 million, with a margin of 1.9 million, 13.8% of supply. By
1997, the margin had decreased to 862,000, 7.2% of
supply. In response to a
sharply increasing demand for
RBCs, blood centers successfully increased allogeneic collections in 1999 to 13.2 million, increasing the margin to
9.1% in spite of an 8.1% in-

further contraction in the margin between supply and demand. The 2004 margin was
the smallest ever measured by
this series of contemporary
national collection and
transfusion surveys.
Through efficient product
management, evidenced by
reduced outdates and low
numbers of hospitals reporting
unmet need, the blood community has maintained adequate supply to meet blood
product needs. The community must remain vigilant,
however, because the margin
is smaller than it has ever
been. We must be able to ensure that the blood supply is
always sufficient for the country’s needs.
