Pilot Study Suggests Large Buying Groups Do Not Always Offer Hospitals 
Lower Prices: 

Statement for the Record by William J. Scanlon: 
Director, Health Care Issues: 
	
GAO-02-690T: 

Mr. Chairman and Members of the Subcommittee: 

We are pleased to have the opportunity to comment on the role of group 
purchasing organizations (GPO) in the marketplace for medical devices 
used in hospitals. Faced with persistent pressures to cut their costs, 
hospitals over the past two decades have increasingly relied on 
specialized private firms—GPOs—to keep the cost of supplies in check. 
Hospitals buy everything from sophisticated medical devices—for 
example, cardiac defibrillators—to commodities such as saline solution 
through GPO-negotiated contracts. By pooling the purchases of their 
member hospitals, these specialized firms are intended to negotiate 
lower prices from vendors (manufacturers and distributors), which can 
benefit hospitals and, ultimately, consumers and payers of hospital 
care (such as insurers and employers). The price advantages of a GPO 
are expected to be greater for large GPOs, which negotiate on behalf 
of nearly 2,000 hospitals. To increase its leverage with vendors, a 
GPO often selects only certain manufacturers and vendors of a product 
to include in its catalog. According to GPOs, this selection of some 
vendors and exclusion of others reflects judgments about both product 
quality and price. 

Some manufacturers—especially small manufacturers of medical devices—
allege that contracting practices of some large GPOs have blocked 
their access to hospitals' purchasing decisionmakers. The 
manufacturers contend that these practices ultimately deny patients 
access to innovative or superior medical devices. These concerns have 
spurred calls for reexamining federal antitrust guidelines regarding 
GPOs. Issued in 1993, these guidelines articulate an antitrust 
enforcement policy that affords GPOs considerable latitude to merge 
and grow. The policy has permitted the creation and growth of the 
largest GPOs, formed in the 1990s. 

To assist the Subcommittee as it considers GPOs' effects on medical 
device purchasing, this statement provides an overview of the GPOs and 
their operations and summarizes results from our pilot study, which 
the Subcommittee requested, of a selected metropolitan area's hospital 
purchasing. This study was exploratory, testing the feasibility of 
collecting price and purchase data for medical devices, and will be 
followed by a broader study covering more areas, devices, GPOs, and 
hospitals. Specifically, this statement details (1) the extent to 
which, in one market, hospitals buying pacemakers and safety needles 
saved money by using a GPO contract and (2) the extent to which these 
hospitals purchased pacemakers and needles from small manufacturers. 
To learn about GPO operations, we interviewed officials of 11 
hospitals, four GPOs, nine medical device manufacturers, two industry 
associations, and the Department of Justice (DOJ). We established the 
feasibility of collecting price and purchase data on medical devices 
by obtaining such data on pacemakers and safety needles[Footnote 1] 
for 2000 from 18 hospitals in one greater metropolitan area.[Footnote 
2] We chose to study pacemakers and safety needles because they are 
two types of medical devices that are commonly purchased by hospitals. 
Hospitals in our sample purchased 121 models of pacemakers and 196 
models of safety needles. We compared GPO-negotiated prices to prices 
obtained by hospitals purchasing on their own. Because all these 
hospitals did not purchase each model, price comparisons were only 
possible for subsets of models. Taken together, comparisons involved 
contracts of eight GPOs, 23 models of safety needles, and 42 models of 
pacemakers. In many cases, more than one hospital purchased a 
particular device; in those cases, the price refers to the median 
price. We also used the purchase data to determine the extent to which 
these hospitals purchased these devices from small manufacturers. We 
did not independently verify the information in appendix I. Our work 
was conducted from October 2001 through April 2002 in accordance with 
generally accepted government auditing principles. 

In summary, for the hospitals that we studied, a hospital's use of a 
GPO contract did not guarantee that the hospital saved money: GPOs' 
prices were not always lower and were often higher than prices paid by 
hospitals negotiating with vendors directly. Specifically, we examined 
price savings with respect to three factors: 

* Whether hospitals using GPO contracts got better prices than 
hospitals that did their own contracting varied widely by product 
model. For some pacemaker models, the hospitals using GPO contracts 
got considerably better prices—up to 26 percent lower than the 
hospitals not using a GPO contract. But for other models, hospitals 
using a GPO contract got prices that were much worse-up to 39 percent 
higher than hospitals not using a GPO contract. Similar results held 
for hospitals using large GPOs—those whose members purchase more than 
$6 billion per year with their contracts—compared to hospitals buying 
on their own. 

* Price savings differed by size of hospital. Large hospitals—those 
with more than 500 beds—often obtained lower prices on their own than 
by using a GPO. By contrast, small and medium-sized hospitals were 
more likely to obtain price savings using a GPO contract. But these 
hospitals' experiences also ranged widely: Some hospitals' GPO 
contract prices were much lower—and others much higher—than prices 
negotiated by hospitals on their own. 

* Price savings had little relationship to the size of the GPO. 
Hospitals using contracts of large GPOs—those whose members purchase 
over $6 billion per year with their contracts—did not necessarily 
obtain better prices than hospitals using smaller GPOs' contracts. 
This lack of consistent price savings is contrary to what would be 
expected for large GPOs. 

In the metropolitan market we studied, hospitals bought pacemakers and 
safety needles predominantly from large manufacturers. We could not 
determine the extent to which hospitals' reliance on large 
manufacturers of these two devices reflected hospitals' independent 
preferences for large manufacturers' products or the effect of GPOs' 
contracting practices on hospitals' purchasing decisions, since almost 
all hospitals in our sample belonged to GPOs. 

The data on hospital purchases in our study market raise questions 
about whether GPOs—and especially large GPOs—achieve price savings 
consistently, as expected. In addition, the limited number of 
purchases from small manufacturers in our study market suggests the 
need to examine data from additional markets, given small 
manufacturers' concerns that GPOs' practices inappropriately limit 
their access to potential purchasers. This additional information on 
price savings and GPO practices could inform an examination of GPOs' 
treatment under federal antitrust policy. 

Background: 

Hospitals' budgets for medical devices and other goods are 
substantial. Many hospitals buy medical devices and other supplies 
through GPOs, which are generally owned by member hospitals and vary 
in size and scope of services. GPOs are expected to use volume 
purchasing as leverage in negotiating prices with vendors. In exchange 
for administrative services and the ability to sell through a GPO to 
its member hospitals, vendors pay administrative fees to a GPO based 
on the hospitals' purchases made using that GPO's contract. These 
fees, sanctioned under Medicare law, cover the GPO's costs; GPOs often 
distribute surplus fees to their owners. Federal antitrust guidelines 
help a GPO determine whether its business practices and market share 
are likely to be questioned as anticompetitive by enforcement agencies. 

Hospitals and Medical Devices: 

According to an American Hospital Association (AHA) survey, roughly 
4,900 nonfederal community hospitals[Footnote 3] spent an estimated 
$173 billion on nonlabor supplies, services, and capital in 2000. A 
significant share of hospitals' nonlabor costs include such goods as 
pharmaceuticals and medical devices. Hospitals buy these goods through 
their own purchasing departments, and many hospitals—in addition to 
contracting on their own with vendors—use GPO-negotiated contracts for 
at least some of their purchasing. Some hospitals have large or more 
sophisticated purchasing operations, but even hospitals belonging to 
large chains or health systems often do at least some purchasing 
through a GPO. The proportion of hospitals belonging to at least one 
GPO is substantial: estimates range from 68 percent to 98 percent. 
[Footnote 4] 

Medical devices that hospitals buy span a wide array of products, such 
as pacemakers, implantable defibrillators, and infusion pumps. Some 
device manufacturers are small companies that offer one product or a 
few closely related products while others are large firms that offer 
many, often unrelated, products. The Medical Device Manufacturers 
Association estimates that some devices become obsolete within 2 to 3 
years—when the next generation of a particular device becomes 
available. Manufacturers market medical devices in medical journals 
and trade shows but place considerable value on having access to 
clinicians in hospitals as well as to hospital purchasing departments, 
which make the final buying decisions. 

GPOs' Size, Structure, and Benefits: 

According to the Health Industry Group Purchasing Association, 
hundreds of GPOs operate today, but only about 30 negotiate sizeable 
contracts on behalf of their members. The emergence of these large 
GPOs in part stems from GPO mergers in the mid-1990s. Joint ventures 
and mergers created the two largest GPOs, Novation and Premier, which 
have annual purchases by member facilities using their contracts of 
$17.6 billion and $14 billion, respectively. Other GPOs in our pilot 
study have less than $6 billion in annual purchases by member 
facilities. (See appendix I for purchasing volumes of GPOs in our 
pilot study.) In addition to differences in size, GPOs differ in 
scope. Some negotiate national contracts and offer many services 
beyond purchasing, such as programs emphasizing the gains in safety 
and economic value resulting from standardization, or specialized 
software to help ensure that hospitals are not overcharged. Others 
serve regional or local hospital markets and provide fewer additional 
services. 

GPOs differ in their corporate structures and their relationships with 
member hospitals. All large GPOs and many smaller GPOs are for-profit 
entities, some of which are owned by not-for-profit hospitals. 
[Footnote 5] Other GPOs have shareholders independent of the member 
hospitals, which themselves do not necessarily hold an ownership 
stake. An example of a for-profit GPO owned by not-for-profit 
hospitals is Premier. Premier is owned by 203 not-for-profit health 
care organizations that operate approximately 900 hospitals. Other for-
profit GPOs are owned by investors that are not member hospitals; for 
example, InSource is owned by MedAssets, a private purchasing and 
contract services company. Broadlane's owners consist of individual 
investors as well as for-profit and not-for-profit organizations 
including Tenet Healthcare, a nationwide provider of health care 
services.[Footnote 6] Some GPOs are jointly owned. For example, both 
Novation and Healthcare Purchasing Partners International (HPPI) are 
owned by the same two networks of hospitals and physicians. Network 
members purchase using Novation contracts. However, non-network 
members purchase using HPPI contracts, which are negotiated by 
Novation. Some GPOs, such as HealthTrust, require that members do not 
belong to other GPOs. In addition, some GPOs, such as Novation and 
Amerinet, contract with manufacturers to supply products sold under 
the GPO's own "private-label" brand name. (See appendix I for a 
summary of characteristics of GPOs in our pilot.) 

According to officials of GPOs and a GPO trade organization, benefits 
that GPOs provide to member hospitals[Footnote 7] include, in addition 
to lower prices, reduced costs due to hospitals being able to reduce 
the size of purchasing departments, as well as assistance with product-
comparison analysis and standardization of products. Benefits that 
GPOs say they provide to manufacturers with which they contract 
include, in addition to access to hospital decisionmakers, cost 
savings due to reducing manufacturers' contracting, marketing, and 
sales activities. According to representatives of some manufacturers, 
many GPOs act as gatekeepers to hospital purchasing decisionmakers and 
charge the manufacturers administrative fees as the price of access to 
their member hospitals. 

GPO Price Negotiation and Administrative Fees: 

In order to sell to hospitals through GPO contracts, vendors generally 
submit proposals to a GPO—in response to Requests for Proposals (RFP)—
that are then evaluated. Based on these evaluations, the GPO enters 
into negotiations with select vendors to determine prices and, in some 
cases, administrative fees that vendors pay to the GPO. Hospitals then 
buy directly from the manufacturer for a price specified in a GPO 
contract. Often prices through a GPO-negotiated contract vary based on 
each hospital's volume of purchases and the extent to which the member 
hospital delivers on its "commitment" to buy an agreed-upon share of 
its purchases of a certain product from a particular manufacturer. 
[Footnote 8] The more of a product that a hospital purchases, the 
lower the price per unit it may pay the manufacturer. A hospital's 
price may also vary depending upon the share of a product it purchases 
from a manufacturer. For example, a hospital that buys only 25 percent 
of its cardiac stents from one manufacturer may pay nearly three times 
more per stent than one that purchases all its stents from that 
manufacturer. Member hospitals may have an additional financial 
incentive to use the GPO contract. The extent to which a hospital buys 
using the GPO's contracts may affect the share of the administrative 
fees that the GPO returns to the hospital. 

Although GPOs provide services to hospitals and are often organized by 
hospitals, many finance their operations primarily through the 
administrative fees paid by manufacturers and other vendors. These 
fees are typically calculated as a percentage of each hospital's 
purchases from a vendor. The Social Security Act, as amended in 1986, 
allows these fees, which would otherwise be considered 'kickbacks' or 
other illegal payments to the GPO.[Footnote 9] Regulations 
establishing appropriate administrative fees, enforced by the Office 
of Inspector General in the Department of Health and Human Services, 
state that the fee structure must be disclosed in an agreement between 
the GPO and each participating member. The agreement must state that 
fees are to be 3 percent or less of the purchase price, or if not 
fixed at 3 percent or less, the amount or maximum amount that each 
vendor will pay. The GPO must also disclose in writing to each member, 
at least annually, the amount received from each vendor with respect 
to purchases made by or on behalf of the member. The fees tend to be 
higher on purchases by hospitals that buy most or all of an item from 
one vendor. In addition to covering their operating expenses with 
these fees, GPOs, with the approval of their boards of directors, 
often distribute surplus fees to member hospitals but may also use 
administrative fees to finance new ventures, such as electronic 
commerce, that are outside their core business. (See figure 1.)

[End of figure] 

The complex financial flows among vendors, GPOs, and hospitals have 
raised concerns that GPOs' interests may diverge from those of 
hospitals. According to some small manufacturers, GPOs have an 
incentive not to seek the lowest price because higher prices yield 
higher administrative fees. These manufacturers further suggest that 
GPOs, by relying on vendors' fees, become agents of manufacturers and 
assist them in limiting competition. By contrast, according to some 
GPOs, they act as an extension of hospitals and GPO members have input 
into the GPOs' product selections. GPOs acknowledge that a 
manufacturer dominant in a product line may contract with a GPO, or 
agree to a favorable contract, to preserve its market share and 
exclude competitors. However, GPOs assert that this selective 
contracting is part of a competitive process allowing the GPO to 
negotiate lower prices. GPOs also emphasize that participation in a 
GPO is voluntary, so the GPO must reflect what the hospitals want if 
it is to retain their business. 

Antitrust: 

Recognizing that joint purchasing arrangements among hospitals may 
enable members to achieve efficiencies that will benefit consumers but 
may, in some cases, pose risks of harming consumers by reducing 
competition, DOJ and the Federal Trade Commission (FTC) issued in 1993 
a guideline to help GPOs and others gauge whether a particular GPO 
arrangement is likely to raise antitrust problems.[Footnote 10] This 
guideline sets forth an "antitrust safety zone" for GPOs that meet a 
two-part test, under which the agencies, absent extraordinary 
circumstances, will not challenge the arrangement as anticompetitive. 
Essentially, the two-part test is as follows: 

1. Purchases through a GPO must account for less than 35 percent of 
the total sales of the product or service in question (such as 
pacemakers) in the relevant market. This part of the test addresses 
whether the GPO accounts for such a large share of the purchases of 
the product or service that it can effectively exercise increased 
market power as a buyer. If the GPO's buying power drives the price of 
the product or service below competitive levels, consumers could be 
harmed if suppliers respond by reducing output, quality, or innovation. 

2. The cost of purchases through a GPO by each member hospital that 
competes with other members must amount to less than 20 percent of 
each hospital's total revenues. This second part of the test looks at 
whether the GPO purchases constitute such a large share of the 
revenues of competing member hospitals that they could result in 
standardizing the hospitals' costs enough to make it easier to fix or 
coordinate prices.[Footnote 11] 

However, the guideline states that a purchasing arrangement is not 
necessarily in violation of the antitrust laws simply because it falls 
outside the safety zone. Likewise, the guideline suggests that even a 
purchasing arrangement that falls within the safety zone might still 
raise antitrust concerns under "extraordinary circumstances." Each 
arrangement has to be examined according to its particular facts. In 
this regard, the guideline also describes factors that reduce 
antitrust concerns with purchasing arrangements that fall outside the 
safety zone. 

Price Savings Not Obtained Consistently with GPO Contract and Savings 
Varied by Model and Size of Hospital: 

GPOs did not always obtain better prices for member hospitals. The 
advantage or disadvantage of GPO prices varied by the model purchased 
and size of hospital—but lacked a clear relationship to size of GPO. 
In our pilot study, we compared median GPO and median non-GPO prices 
for purchases by hospitals and found the following: 

* Among hospitals of all sizes, hospitals using GPO-negotiated 
contracts to buy pacemakers and safety needles often paid more than 
hospitals negotiating on their own. This finding also held for 
hospitals using large GPOs, compared to hospitals negotiating on their 
own. 

* Between hospitals of different sizes, small and medium-sized 
hospitals buying pacemakers were more likely than large hospitals to 
save money when using GPO-negotiated contracts.[Footnote 12] 

We also compared prices between large GPOs and smaller GPOs: Hospitals 
of all sizes using a large GPO's contracts almost always saved money 
on safety needles but often paid more for pacemakers, compared to 
those using smaller GPOs' contracts. Large GPOs would be expected to 
achieve price savings consistently. In all these comparisons, the 
price savings or additional cost that hospitals realized—for example, 
by using a GPO or by negotiating on their own—often varied widely from 
model to model. 

Use of GPO Contract Often Did Not Yield Price Savings for Hospitals 
Buying Pacemakers and Safety Needles: 

Purchasing with GPO contracts did not ensure that hospitals saved 
money. Among hospitals of all sizes in our study market, those using 
GPO-negotiated contracts for pacemakers and safety needles often paid 
more than those negotiating on their own. The median GPO-negotiated 
price was higher than the median price hospitals paid on their own for 
all six safety needles models and over three-fifths of the 41 
pacemaker models that could be compared.[Footnote 13] Similarly, the 
use of a large GPO—one with an annual purchase volume greater than $6 
billion—did not guarantee price savings. Hospitals using contracts 
negotiated by a large GPO paid more than hospitals purchasing on their 
own for the six safety needle models and roughly half of the 22 
pacemaker models that could be compared. 

The price savings or additional costs that hospitals obtained using 
GPO-negotiated contracts varied by model. For different safety needle 
models, median GPO-negotiated prices exceeded prices negotiated by a 
hospital buying on its own by from 1 percent to 5 percent. For 
different pacemaker models, the variation was much greater: median GPO-
negotiated prices ranged from 26 percent less to 39 percent more than 
the median price paid by hospitals purchasing on their own. (See 
figure 2.)

Non-GPO Contract Prices for 41 Pacemaker Models:

The graph depicts percentage price differential for the following 41 
models: 

Models for which GPO contracts yielded savings compared to hospitals 
purchasing on their own (13 models); 
Models for which GPO contracts did not yield savings compared to 
hospitals purchasing on their own (25 models). 

Models 14, 15, and 16 had zero price differential. 

Note: Each bar refers to a different model of pacemaker. The length of 
the bar reflects the difference between the price paid by hospitals 
using GPO contracts and the price paid by hospitals not using GPO

and used in comparisons that included more than one GPO-negotiated 
price or hospital purchasing on its own.

Small and Medium-Sized Hospitals More Likely Than Large Hospitals to 
Realize Price Savings on Pacemakers with GPO Contract: 

We examined how hospitals of different sizes using GPOs fared relative 
to their peers purchasing pacemakers on their own and found that 
whether there were savings depended on the size of the hospital. 
[Footnote 14] The 4 small hospitals (those with fewer than 200 beds) 
always did better with a GPO contract. The 11 medium-sized hospitals 
(those with 200 to 499 beds) did better with a GPO contract for 40 
percent of the models (see figure 3), and the 3 large hospitals rarely 
did better with a GPO contract—compared with their respective peers 
purchasing on their own (see figure 4). Even though small hospitals 
buying on their own generally paid higher prices than the small 
hospitals using GPOs, the GPO-negotiated price was not much lower—from 
1 to 6 percent—than what they paid on their own. 

Figure 3: Differences between Median GPO Contract Prices and Median 
Non-GPO Contract Prices for 25 Pacemaker Models Purchased by Medium-
Sized Hospitals: 

[Refer to PDF for image: vertical bar graph] 

The graph depicts percentage price differential for the following 25 
models: 

Models for which GPO contracts yielded savings compared to hospitals 
purchasing on their own (10 models); 
Models for which GPO contracts did not yield savings compared to 
hospitals purchasing on their own (14 models). 

Model 11 had zero price differential. 

Note: Each bar refers to a different model of pacemaker. The length of 
the bar reflects the difference between the price paid by medium-sized 
hospitals using GPO contracts and the price paid by medium-sized 
hospitals not using GPO contracts to purchase the same model. Medium-
sized hospitals are hospitals with from 200 to 499 beds. Median prices 
were calculated and used in comparisons that included more than one 
GPO-negotiated price or hospital purchasing on its own. 

Source: GAO survey of hospitals in a greater metropolitan area. 

[End of figure] 

As figures 3 and 4 show, the range of price savings or additional 
costs associated with GPO contracts was considerable. For example, for 
medium-sized hospitals, the median GPO-negotiated price was 39 percent 
lower for model 1 and 25 percent higher for model 25 than the median 
price paid by these hospitals purchasing on their own. 

Figure 4: Differences between GPO Contract Prices and Non-GPO Contract 
Prices for 11 Pacemaker Models Purchased by Large Hospitals:

Note: Each bar refers to a different model of pacemaker. The length of 
the bar reflects the difference in the price paid by large hospitals 
using GPO contracts and the price paid by large hospitals not using 
GPO contracts to purchase the same model. Large hospitals are 
hospitals with 500 or more beds. Median prices were calculated and 
used in comparisons that included more than one GPO-negotiated price 
or hospital purchasing on its own.

Compared to Smaller GPOs, Use of Large GPOs Yielded Price Savings for 
Needles—Less Often for Pacemakers: 

The size of a GPO was not related consistently to whether a hospital, 
when using a GPO contract, obtained a better price. Whether use of 
large GPOs offered price savings varied by type of device: for safety 
needles, they were more likely to obtain better prices and for 
pacemakers, they were less likely to do so. Specifically, the median 
price paid by hospitals using a large GPO's contract to purchase 
safety-needles was nearly always lower—for 18 of the 19 types of 
needles we could compare—than the median price paid by hospitals using 
a smaller GPO's contract. For pacemakers, a large GPO's contract 
infrequently yielded better prices than smaller GPOs' contracts—for 
only 5 of the 18 pacemakers we could compare. In this case, the higher 
prices associated with most of these pacemaker purchases run counter 
to the expectation that large GPOs yield substantial price advantages. 
(See figure 5.) 

Figure 5: Differences in Median Prices between a Large GPO's Contracts 
and Other GPOs' Contracts for 18 Pacemaker Models: 

[Refer to PDF for image: vertical bar graph] 

The graph depicts percentage price differential for the following 18 
models: 

Models for which large GPO contracts yielded savings compared to 
smaller GPO contracts (5 models); 
Models for which large GPO contracts did not yield savings compared to 
smaller GPO contracts (12 models). 

Model 6 had zero price differential. 

Note: Each bar refers to a different model of pacemaker. The length of 
the bar reflects the difference in the price paid by hospitals using a 
large GPO's contract—one whose members purchase over $6 billion per 
year with its contracts—and the price paid by hospitals using smaller 
GPOs' contracts to purchase the same pacemaker model. Median prices 
were calculated and used in comparisons that included more than one 
GPO-negotiated price or hospital purchasing on its own. 

Source: GAO survey of hospitals in a greater metropolitan area. 

[End of figure] 

Figure 5 shows that, as with the previous comparisons, the range of 
price savings or additional costs associated with large GPOs was wide. 
For hospitals using large GPOs' contracts to buy pacemakers, the 
median price paid ranged from 20 percent less for one model to 26 
percent more for another, compared with the median price paid by 
hospitals using smaller GPOs' contracts. 

Hospitals Rarely Purchased Selected Medical Devices from Small 
Manufacturers: 

Regardless of whether a GPO contract was used, hospitals bought 
pacemakers and safety needles predominantly from large manufacturers. 
[Footnote 15] In our study, 5 of the 16 manufacturers from which 
hospitals purchased were small; however, purchases from these 5 
represented a small minority of the models bought (1 of 121 pacemaker 
models and 22 of 196 safety needle models). Almost all purchases from 
small manufacturers in our pilot were made by hospitals buying on 
their own; only one hospital purchased from a small manufacturer using 
a GPO contract. 

We could not determine the extent to which hospitals' reliance on 
large manufacturers of these two devices reflected hospital preference 
or the effects of GPOs' contracting practices, because almost all 
hospitals in our sample belonged to GPOs. Representatives from small 
manufacturers whom we interviewed stated that some incentives in GPO 
contracts penalize hospitals purchasing off-contract. However, 
hospital personnel whom we interviewed emphasized different factors as 
influencing their purchasing decisions, including clinical 
considerations for pacemakers and cost for safety needles. Seventy-one 
percent of hospitals purchased a pacemaker and 15 percent a safety 
needle outside of their GPO contracts. 

Concluding Observations: 

While this is a pilot study based on one market, the data raise 
questions about one of the intended benefits from having large GPOs. 
In our study market, GPOs of different sizes realized comparable 
savings for member hospitals. Buying through a large GPO did not 
guarantee a hospital the lowest prices. In fact, there were several 
instances in which individual hospitals using a large GPO's contracts 
paid prices that were at least 25 percent higher than prices 
negotiated by hospitals on their own, and smaller GPOs also sometimes 
offered better prices. Clearly, more evidence on GPOs and their 
effects is needed, since our data pertain to one urban market, two 
types of medical devices, eight GPOs, and 18 hospitals. To assist the 
Subcommittee, we plan to obtain data from a broader array of 
geographic areas and for other devices, hospitals, and GPOs. Gathering 
additional information on GPOs' benefits and possible drawbacks could 
inform an examination of antitrust policy toward GPOs.

Footnotes: 

[1] The term safety needle includes many different types of devices 
with features to reduce the risk of needlestick injuries for health 
care workers. 

[2] Price data did not reflect manufacturers' rebates—which hospitals 
may receive regardless of whether they used a GPO contract or 
purchased items on their own—or other payments earned by hospitals 
purchasing with a GPO contract. In our statement, the term "hospitals" 
refers to single facilities as well as health systems with multiple 
hospitals. Seven hospitals reported safety needle data for 2001. 

[3] Community hospitals include all nonfederal short-term general and 
special hospitals whose facilities and services are available to the 
public. Most community hospitals have fewer than 200 beds while 
roughly 5 percent have over 500 beds. 

[4] AHA survey data indicate that 68 percent of hospitals belonged to 
a GPO in 2000 while, according to the Health Industry Group Purchasing 
Association, 96 to 98 percent of hospitals belonged to a GPO. 

[5] Hospital-owned GPOs may have non-owning members (affiliates), in 
addition to member hospitals that are shareholders. 

[6] InSource is one of two GPOs owned by MedAssets. Broadlane began as 
a division of Tenet Healthcare, which is now one of its owners. 

[7] In addition to hospitals, many GPOs include as members other 
health care organizations, such as nursing facilities. We focus on 
hospitals, which are key buyers in the medical device market. 

[8] Volume and commitment are also important factors in manufacturers' 
contracts with hospitals that purchase without using a GPO contract. 

[9] Any return of a portion of a purchaser's payment for the purpose 
of obtaining favorable treatment in connection with a contract may be 
considered a kickback.

[12] We compared GPO-negotiated prices to non-GPO prices for each size-
category of hospital separately. For example, prices were compared for 
large hospitals using GPO contracts with large hospitals buying on 
their own. 

[13] Price comparisons include instances in which only the purchases 
of two or three hospitals could be included. 

[14] Comparisons by hospital-size for the purchase of safety needles 
were not possible. Several small and medium-sized hospitals did not 
purchase safety needles. Of those that did buy safety needles, the 
majority used GPO contracts for all their purchases or bought items 
for which there was no comparable purchase without a GPO contract. 

[15] For our study, we defined small manufacturers of safety needles 
as those with 500 or fewer employees and small manufacturers of 
pacemakers as those with a market share of less than 10 percent.
