The Deteriorating Administrative Efficiency of the US
Health Care System
Reprinted from the New England Journal of Medicine
324:1253-1258 (May 2), 1991
Abstract Background and Methods. In 1983 the proportion of
health care expenditures consumed by administration in the
United States was 60 percent higher than in Canada and 97
percent higher than in Britain. To asses the effects of recent
health policy initiatives on the administrative efficiency of
health care, we examined four components of administrative
costs in the United States and Canada for 1987: insurance
overhead, hospital administration, nursing home
administration, and physicians’ billing and overhead
expenses. Most data were provided by the two nations’
federal health and statistics agencies, supplemented by state
and provincial data and published sources. Because data on
physicians’ billing costs were limited, we estimated a range
for these costs by two methods that rely on different sources
of data. All figures are reported in 1987 U.S. dollars.
Results. In 1987 health care administration cost between $96.8
billion and $120.4 billion in the United States, amounting in
19.3 to 24.1 percent of total spending on health care, or $400
to $497 per capita. In Canada, between 8.4 and 11.1 percent of
health care spending ($117 to $156 per capita) was devoted to
administration. Administrative costs in the United States
increased 37 percent in real dollars between 1983 and 1987,
whereas in Canada they declined. The proportion of health care
spending consumed by administration is now at least 117
percent higher in the United States than in Canada and
accounts for about half the total difference in health care
spending between the two nations. If health care had been as
efficient as in Canada, $69.0 billion to $83.2 billion would
have been saved in 1987.
Conclusions. The administrative structure of the U.S. health
care system is increasingly inefficient as compared with that
of Canada’s national health program. Recent health policies
with the avowed goal of improving the efficiency of care have
imposed substantial new bureaucratic costs and burdens. (N
Engl J Med 1991; 324:1253-8.)
MEDICINE is increasingly a spectator sport. Doctors,
patients, and nurses perform before an enlarging audience of
utilization reviewers, efficiency experts, and cost managers
(Fig. 1) .A cynic viewing the uninflected curve of rising
health care spending might wonder whether the cost-containment
experts cost more than they contain; one is reminded of the
Chinese proverb “There is no use going to bed early to save
candles if the result is twins.”
In 1983 the proportion of health care spending consumed by
administrative costs in the United States was 60 percent
higher than in Canada and 97 percent higher than in Britain.2
Recent U .S. health policies have increased bureaucratic
burdens and curtailed access to care. Yet they have failed to
contain overall costs. This study updates and expands
estimates of the costs of health administration in North
America through 1987.2 The results demonstrate that the
bureaucratic profligacy of the U.S. health care system has
increased sharply, while in Canada the proportion of spending
on health care consumed by administration has declined.
METHODS
We examined four components of administrative costs in the
United States and Canada: insurance overhead, hospital
administration, nursing home administration, and physicians’
overhead and billing expenses. All estimates are for fiscal
year 1987, the most recent year for which complete data were
available. Costs are reported in 1987 U.S. dollars, based on
the 1987 exchange rate of $1.33 (Canadian) = $1 (U.S.);
calculations of per capita spending were based on populations
of 243,934,000 in the United States and 25,652,000 in Canada.
Figures on insurance overhead in the United States were
obtained from the Health Care Financing Administration.3
Although nationwide data on the costs of hospital and nursing
home administration were not available, the California Health
Facilities Commission regularly compiles detailed cost data,
based on Medicare cost reports, on that state’s hospitals
and nursing homes. Four years ago we confirmed that
administrative costs in California’s health facilities were
similar to those in at least two other states.2 Since then,
trends in hospital and nursing home financing and organization
in California have paralleled developments in the nation as a
whole.4,5 We computed total hospital administrative costs by
summing costs in the following categories: general accounting,
patient accounting, credit and collection, admitting, other
fiscal services, hospital administration, public relations,
personnel department, auxiliary groups, data processing,
communications, purchasing, medical library, medical records,
medical-staff administration, nursing administration,
in-service education, and other administrative services. We
excluded costs attributed to research administration,
administration of educational programs, printing and
duplicating, depreciation, amortization, leases and rentals,
insurance, licenses, taxes, central services and supply, other
ancillary services, and unassigned costs. We assumed that
administration represented the same proportion of total
hospital costs in California as nationwide. We derived
estimates of nationwide administrative costs for nursing homes
from the California data in a similar manner.
Although Canada’s 10 provincial health programs differ in
some details, they share common structural features that tend
to streamline bureaucracy. Each program provides comprehensive
coverage for virtually all provincial residents under a single
publicly administered plan. Private insurance may cover
additional services, but duplication of the public coverage is
proscribed; hospitals are paid a lump-sum (global) amount to
cover operating expenses, and physicians bill the program
directly for all fees.
The Health Statistics Branch of Health and Welfare Canada
and Statistics Canada’s Canadian Center for Health
Information provided unpublished data on nationwide spending
for insurance, hospitals, and nursing homes. These data were
derived from the provincial governments’ reports of their
expenditures for insurance administration and from detailed
cost reports submitted by hospitals and nursing homes. We
computed total hospital administrative costs by summing costs
in the following categories: hospital administration
(“other”), advertising, association-membership fees,
business machines, collection fees, postage, auditing and
accounting fees, other professional fees (such as legal fees
but excluding medical fees), service-bureau fees, telephone
and telegraph, indemnity to board members, travel and
convention expenses, medical records and hospital library, and
nursing administration. We excluded administrative and support
services for educational and research programs, insurance,
interest, printing, stationery and office supplies, materiel
management, and central supply. Statistics Canada tabulates
administrative costs for nursing homes as a single category.
These data are less reliable than the hospital figures, since
cost reporting by nursing homes is voluntary, and the number
of facilities reporting varies substantially from year to
year.
We confirmed the accuracy of the Canadian federal data,
using more detailed but incomplete data from British Columbia,
the Maritimes, Ontario, Quebec, and Saskatchewan6-10 (and
personal communications: Cunningham D, British Columbia
Ministry of Health; Lim P, Continuing Care Employee Relations
Association of British Columbia; and Davis J, Ontario Ministry
of Health). Because these data generally matched the national
figures, we have not reported them separately.
Only indirect or incomplete information is available on the
billing costs of Canadian and U.S. physicians. We therefore
used two different methods to estimate these costs, one based
on physicians’ reports of their professional expenses and
the other on the numbers of employees in physicians’
offices. The expense-based method (Method I) probably
overestimates the actual difference in billing costs between
the two nations, whereas the personnel-based approach (Method
2) may underestimate the difference.
Our first approach, Method I, rests on the assumption that
the entire difference in physicians’ billing and overhead
expenses (excluding malpractice premiums11,12) between the
United States and Canada is attributable to the excess
administrative costs borne by American doctors. The American
Medical Association (AMA) estimates U.S. physicians’ incomes
and practice expenses on the basis of the results of a survey
of a representative sample of nonfederal, practicing
physicians (excluding interns and residents).12 Revenue Canada
tabulates physicians’ professional expenses on the basis of
tax returns (Rehmer L, Health Information Division, Health and
Welfare Canada: personal communication). Because these figures
are “distorted, primarily because of the way group practice
physicians tend to report expenses” (Rehmer L, Health
Information Division, Health and Welfare Canada: personal
communication), we used Revenue Canada’s corrected
tabulation, which included only the 91 percent of physicians
who reported professional expenses amounting to between 5
percent and 300 percent of their net in- comes. We added to
both the U.S. and Canadian figures an estimate of the value of
the physicians’ time devoted to billing13 (and Peachey D:
personal communication); we assumed that this time was valued
at the same rate as other professional activity.
Using Method 2, we also estimated physicians’ billing
costs on the basis of data on the number of clerical and
managerial personnel employed in their offices, as well as the
costs of outside billing services. For the United States, we
obtained information on physicians’ office personnel from
data tapes from the Census Bureau’s March 1988 Current
Population Survey (CPS).14 Since comparable survey data were
unavailable for Canada, we used information from a detailed
study of office staffing patterns in the province of Quebec in
1977.15 These earlier figures were slightly higher than
informal current estimates provided by the Ontario Medical
Association (Peachey D: personal communication). For both the
United States and Canada, we assumed that the total annual
cost per employee averaged $35,000 (including wages, benefits,
taxes, work space, equipment, telephone, supplies, and other
costs attributable to the employee) and that the ratio of
clerical workers to physicians (excluding residents) was
identical in offices and other settings. We added to both the
U.S. and Canadian figures estimates of the value of
physicians’ personal time spent on billing, calculated as
described above. For the United States we added the cost of
outside billing services as determined by a recent survey by
the AMA.13
Finally, to evaluate trends over time, we recalculated the
1987 figures to maintain strict comparability with the less
detailed and less complete data for 1983.2 As in our earlier
paper,2 we estimated physicians’ billing and overhead costs
by the expense-based method (Method I). However, we excluded
the cost of physicians’ time spent on billing because
comparable data were unavailable for 1983. In keeping with our
earlier method, we included malpractice costs in physicians’
overhead expenses but corrected for increases over time in
these costs.11,12,16 For each country we took average total
professional expenses in 1987, subtracted the average 1987
malpractice premium, then added the average 1983 malpractice
premium (all expressed as a percentage of gross income). The
1983 figures were converted to 1987 dollars with use of the
gross-domestic-prodct price index for each country.17
RESULTS
Insurance Overhead
In 1987 private insurance firms in the United States
retained $18.7 billion for administration and profits out of
total premium revenues of $157.8 billion.3 Their average
overhead costs (11.9 percent of premiums) were considerably
higher than the 3.2 percent administrative costs of government
health programs such as Medicare and Medicaid ($6.6 billion
out of total expenditures of $207.3 billion).3 Together,
administration of private and public insurance programs
consumed 5.1 percent of the $500.3 billion spent for health
care, or $106 per capita.
The overhead costs for Canada’s provincial insurance
plans amounted to $235 million (0.9 percent) of the $26.57
billion spent by the plans17 (and Health Information Division,
Health and Welfare Canada: personal communication). The
administrative costs of Canadian private insurers averaged
10.9 percent of premiums ($200 million of the $1.83 billion
spent for such coverage) (Health Information Division, Health
and Welfare Canada: personal communication). Total
administrative costs for Canadian health insurance consumed
1.2 percent of health care spending, or $17 per capita.
Hospital Administration
Hospital administration represented 20.2 percent of
hospital costs in California in 1987-1988.18 Extrapolating
this figure to the total U .S. hospital expenditures of $194.7
billion in 19872 yielded an estimate of $39.3 billion, or $162
per capita, consumed by hospital administration. In Canada,
hospital administration cost $1.27 billion, amounting to 9.0
percent of total hospital expenditures of $14.14 billion
(Health Information Division, Health and Welfare Canada:
personal communication), or $50 per capita.
Nursing Home Administration
The administrative costs in California’s nursing homes
accounted for 15.8 percent of total revenues in 1987-1988.19
On the basis of this figure, we estimate that administration
cost $6.4 billion of the $40.6 billion spent nationally for
nursing home care,3 or $26 per capita. Canadian nursing homes
spent $231 million on administration in 1987-1988, amounting
to 13.7 percent of the total expenditures of $1.69 billion
(Statistics Canada, Canadian Center for Health Information:
personal communication), or $9 per capita.
The data are from Statistical Abstract of the United States
for these years (Table 64-2, 109th edition).1 Because of a
modification in the Bureau of the Census’ definition of
“health administrators,” the change between 1982 and 1983
is interpolated rather than actual.
Physicians’ Billing Expense
Method 1
When calculated according to Method 1, U .S. physicians’
overhead and billing expenses, excluding malpractice premiums,
made up 43.7 percent of their gross professional income12 -
$44.9 billion of the $102.7 billion spent for physicians’
services.3 In addition, physicians spent an average of six
minutes on each Medicare and Blue Shield claim.13 Assuming
that the time required to bill other insurers was similar, the
average physician spent about 134.4 hours per year (4.4
percent of his or her total professional activity) on billing;
this time had a total value of $4.5 billion. Thus, the total
value of U .S. physicians’ billing and overhead was $49.4
billion, or $203 per capita.
Canadian physicians’ professional expenses, excluding
malpractice premiums, amounted to $1.99 billion, or 34.4
percent of their gross income (Rehmer L: personal
communication). According to the director of professional
affairs of the Ontario Medical Association, “The commitment
of time to billing . . . is trivial and can be measured in
seconds [per claim]” (Peachey D: personal communication).
Assuming that the average physician spends 1 percent of his or
her professional time on billing, with a total value of $58
million annually, the total cost of physicians’ billing and
overhead was $2.04 billion, or $80 per capita.
Method 2
The average office-based physician in the United States
employed 1.47 clerical and managerial workers (Himmelstein DU,
Woolhandler S: unpublished data), at an annual cost of $51,564
per physician, for a total of $20.0 billion. As calculated
above (Method 1), the time physicians spent on billing was
valued at $4.5 billion. In addition, 13.9 percent of
physicians contracted with outside billing firms, at an
average annual cost of $23,196 each,13 for a total of $1.3
billion. Physicians’ total billing and clerical expenses
amounted to $25.8 billion, or $106 per capita.
The average office-based general practitioner in Quebec
employed 0.733 receptionists and secretaries15 at an annual
cost of $25,655 per physician, for a total of $1.0 billion for
Canadian physicians. In addition, the time physicians spent on
billing was valued at $58 million. Physicians’ total billing
and clerical expenses were thus $1.06 billion, or $41 per
capita.
Total Costs of Administration
Table 1 summarizes the per capita costs of health care
administration in the United States and Canada, including
physicians’ billing and overhead costs as calculated by the
two different methods. Overall expenditures for health care
administration in the United States totaled $96.8 billion to
$120.4 billion ($400 to $497 per capita), accounting for 19.3
to 24.1 percent of the $500.3 billion spent for health care.
Canadians spent $3.00 billion to $3.98 billion for health care
administration ($117 to $156 per capita), amounting to 8.4 to
11.1 percent of the $35.9 billion spent for health care. The
difference of $283 to $341 in the per capita cost of health
care administration and billing accounted for 43.5 to 52.5
percent of the total difference in health spending between the
two nations. If U.S. health care administration had been as
efficient as Canada’s, $69.0 to $83.2 billion (13.8 to 16.6
percent of total spending on health care) would have been
saved in 1987.
The difference between the United States and Canada in
billing and administrative costs has markedly increased since
1983.2 Insurance overhead in the United States has risen from
4.4 percent to 5.1 percent of total health care spending,
whereas insurance overhead in Canada has declined from 2.5
percent to 1.2 percent.2 Hospital administrative costs have
risen from 18.3 percent to 20.2 percent of total hospital
spending in the United States, whereas in Canada these costs
have climbed slightly from 8.0 percent to 9.0 percent.2
Administrative expenses in U.S. nursing homes rose from 14.4
percent to 15.8 percent of costs, whereas administration’s
share of total costs rose from 10.5 to 13.7 percent in
Canada.2 Physicians’ professional expenses (excluding
malpractice premiums) have increased from 41.4 percent to 43.8
percent of gross income in the United States, whereas the
Canadian figure declined from 35.5 percent to 34.4 percent.2
Table 1. Cost of Health Care Administration in the United
States and Canada, 1987.

When we recalculated the 1987 figures to maintain
comparability with the less complete 1983 data, we found that
U.S. administrative costs rose from 21.9 percent to 23.9
percent of health care spending between 1983 and 1987, whereas
in Canada administrative costs declined from 13.7 percent to
11.0 percent.2 After adjustment for inflation, the divergence
was even more striking. The costs of the health care
bureaucracy in the United States rose by $32.2 billion (37
percent) between 1983 and 1987, an increase of $118 per
capita. Administrative costs in the Canadian health care
system fell by $161 million during this period, a decrease of
$6 per capita.
DISCUSSION
Most of our analysis is based on well-substantiated data,
although in some areas reliable figures are sparse. The
comparability of the data on hospital administrative costs in
Canada and the United States is uncertain. However, we relied
on detailed budgetary categories that appeared closely matched
in the two nations. Although data on the administrative costs
of health maintenance organizations are limited, they do not
appear to differ substantially from those in the U .S.
fee-for-service sector.20-22
Both of our methods for estimating physicians’ billing
costs are imprecise. The expense-based method (Method 1) may
overstate the difference between the United States and Canada,
since it assumes that the entire discrepancy in the proportion
of income devoted to professional expenses was accounted for
by mal- practice premiums, billing, and administration. The
personnel-based method (Method 2) may understate the
difference because it assumes that aides and other clinical
personnel employed in physicians’ offices per- formed no
activities related to billing, that the total annual cost per
clerical worker was no less in Canada than in the United
States, and that Canadian billing operations have not been
streamlined since 1977 despite computerization. An official of
the Ontario Medical Association estimates that electronic
claims submission and reconciliation takes about one sixth as
much staff time as paper-based billing (Peachey D: personal
communication).
In the United States, clerical and managerial staff
accounted for 59.5 percent of the nonphysician employees in
doctors’ offices in 1988, and 74,700 more were added over
the ensuing two years (Himmelstein DU, Woolhandler S:
unpublished data). In contrast, technicians and technologists
accounted for only 7.3 percent of nonphysician office workers
in 1988 and for only 5.7 percent in 1990 (Himmelstein DU,
Woolhandler S: unpublished data). In 1988, the staff in a
typical U.S. physician’s office spent about one hour on each
Blue Shield or Medicare claim,13 at least 20 times more than
in Ontario (Peachey D: personal communication; Weinkauf D:
personal communication). In a typical practice in Canada,
“One person does all the billing, bookkeeping and typing . .
. for 8 physicians.”23
Our estimates omit the administrative costs of union and
employer health-benefit programs and the administrative work
done by hospital nurses and other nonphysician clinical
personnel- all probably greater in the United States than in
Canada. Moreover, patients in the United States spend far more
time (and anguish) on insurance paperwork than do Canadians;
these costs are not reflected in our figures. On the other
hand, some argue that funding health services through taxes,
as in Canada, erodes productivity throughout the economy by
discouraging work and investment - the so-called dead-weight
loss.24 Within the range of tax rates in North America,
however, the magnitude, and even existence, of this
dead-weight loss is controversial.25
The United States spent 37 percent more in real dollars on
health administration in 1987 than in 1983.2 The recent quest
for efficiency has apparently amplified inefficiency.
Cost-containment programs predicated on stringent scrutiny of
the clinical encounter have required an army of bureaucrats to
eliminate modest amounts of unnecessary care. Each piece of
medical terrain is meticulously inspected except that beneath
the inspectors’ feet. Paradoxically, the cost-management
industry is among the fastest-growing segments of the health
care economy and is expected to generate $7 billion in
revenues by 1993.26 The focus on micromanagement has obscured
the “fundamentally inefficient structure required to
implement such policies. In contrast, Canada has evolved
simple mechanisms to enforce an overall budget, but it allows
doctors and patients wide latitude in deciding how the funds
are spent. Reducing our administrative costs to Canadian
levels would save enough money to fund coverage for all
uninsured and underinsured Americans.27 Universal
comprehensive coverage under a single, publicly administered
insurance program is the sine qua non of such administrative
simplification.
The fragmented and complex payment structure of the U.S.
health care system is inherently less efficient than the
Canadian single-payer system. The existence of numerous
insurers necessitates determinations of eligibility that would
be superfluous if everyone were covered under a single,
comprehensive program. Rather than a single claims-processing
apparatus in each region, there are hundreds. Fragmentation
also reduces the size of the insured group, limiting savings
from economies of scale. Insurance overhead for U.S. employee
groups with fewer than 5 members is 40 percent of premiums but
falls to 5.5 percent for groups of more than 10,000.28
Competition among insurers leads to marketing and cost
shifting, which benefit the individual insurance firm but
raise systemwide costs.
A lack of comprehensiveness in coverage also drives up
administrative costs. Copayments, deductibles, and exclusions
are expensive to enforce and lead many enrollees to purchase
secondary “Medigap” policies. The secondary insurers
maintain redundant and ex- pensive bureaucracies.29
The efficiency of U.S. health care is further compromised
by the extensive participation of private insurance firms
whose overhead consumes 11.9 percent of premiums, as compared
with 3.2 percent in U .S. public programs.3 Even the
“public” figure reflects the inefficiency of the private
firms that process claims for Medicare for an average of $2.74
per claim,30 whereas Ontario’s Ministry of Health processes
claims for $0.41 each (Davis J: personal communication).
Moreover, the inefficiency of private insurers is not unique
to the United States. The small private-insurance sectors of
Canada, the United Kingdom, and Germany have overheads of 10.9
percent, 16 percent, and 15.7 percent, respectively.31,32 A
major advantage of public programs in terms of efficiency is
their use of existing tax-collection structures, obviating the
need for a redundant bureaucracy to collect money for health
services. Thus, the overhead in Germany’s premium- based,
quasi-public sickness funds is between 4.6 percent33 and 4.8
percent (Kuhn H: personal communication) - considerably higher
than the overhead in tax-funded systems.
The scale of waste among private carriers is illustrated by
Blue Cross/Blue Shield of Massachusetts, which covers 2.7
million subscribers and employs 6682 workers34 - more than
work for all of Canada’s provincial health plans, which
together cover more than 25 million people7-10 (and Davis]:
personal communication; Cunningham D: personal communication);
435 provincial employees administer the coverage for more than
3 million people in British Columbia (Cunningham D: personal
communication).
The existence of multiple payers in the United States also
imposes bureaucratic costs on health care providers. Hospitals
must bill several insurance programs with varying and
voluminous regulations on coverage, eligibility, and
documentation. Moreover, billing on a per-patient basis
requires an extensive internal accounting apparatus for
attributing costs and charges to individual patients and
insurers. In contrast, Canada’s single-payer system funds
hospitals through global budgets, eliminating almost all
hospital billing. The striking administrative efficiency of
the Shriners’ hospitals in the United States, which bill
neither patients nor third parties and devote only 2 percent
of their revenues to administration,35 suggests that payment
mechanisms rather than cultural or political milieus determine
administrative costs. Here, too, the European experience
parallels North America’s. British hospitals that are
assigned global budgets devote 6.9 percent of spending to
administration,36 but those paid on a per-patient basis (such
as Humana’s Wellington Hospital in London) spend 18
percent.37
The synchronous growth of bureaucratic profligacy and unmet
health needs is reminiscent of Dickens’ somber tale of six
poor travelers who were relegated to outbuildings when the
hostel built for them was fully occupied by its charitable
administrators.
I found, too, that about a thirtieth part of the annual
revenue was now expended on the purposes commemorated in the
inscription over the door; the rest being handsomely laid out
in Chancery, law expenses, collectorship, receivership,
poundage, and other appendages of management, highly
complimentary to the importance of the six Poor Travellers.38
The house of medicine is host to a growing array of
specialists in fields unconnected to healing. At its present
rate of growth, administration will consume a third of
spending on health care 12 years hence, and half of the health
care budget in the year 2020.
We are indebted to Mr. Lothar Rehmer, Ms.Judith Dowler, Dr.
Jane Fulton, and Mr. Gilles Fortin for providing much of the
raw data on Canadian health spending and to Dr. David H. Bor
for his invaluable advice.
