National health expenditures, 1978.

Outlays for health care in the Nation reached $192.4 billion in calendar year 1978--13 percent higher than in 1977, according to preliminary figures compiled by the Health Care Financing Administration. This estimate represented $863 per person in the United States and was equal to 9.1 percent of the GNP. This latest report in the annual series representing national health expenditures provides detailed estimates of health care spending by type of service and method of financing. Revised estimates are presented extending back to 1965.

The Nation spent an estimated $192 billion for health care in 1978, an amount equal to 9.1 percent of the Gross National Product. Highlights of the figures behind this estimate reveal that.

Health care expenditures amounted to $192.4 billion in 1978, or $863 per person. Health spending represented 9.1 percent of the Gross. National Product.

Health spending in 1978 increased 13.2 percent over the previous year, a slight decrease from the 14.2 increase recorded in 1977.

Spending by all government programs ($78.1 billion) increased 12.7 percent in 1978; private spending increased 13.5 percent. Public spending represented 41 percent of all 1978 money spent for health care.

All third parties combined--private health insurers, governments, philanthropy and industry--financed 67 percent of personal health care in 1978, ranging from 90 percent of hospital care services; 66 percent of physicians' services; and 37 percent of the remainder.

Outlays for health care benefits by the Medicare and Medicaid programs amounted to $43.3 billion in 1978--26 percent of the $167.9 billion spent for personal health care.

Expenditures' for hospital care represented 40 percent of total health spending in 1978. These expenditures increased 11.9 percent in 1978 to a level of $76.0 billion.

Spending for the services of physicians increased 12.8 percent to $35.2 billion, 18 percent of all health spending in 1978.

This latest compilation of the dollars spent for health care in the Nation in 1978 is a continuation of the series of annual reports begun by the Office of Research and Statistics of the Social Security Administration and now the responsibility of the Office of Research, Demonstrations, and Statistics of the Health Care Financing Administration. It represents a departure from reports of recent years in that data are presented for calendar years, rather than for the Federal fiscal year. The data for the Federal fiscal year, along with data for years ending in March and June, will be presented in the forthcoming series, Health Care Financing Trends. The expenditures have been revised back to 1965 to reflect changes in some basic data sources as well as improvements in methodology.

Overview

Preliminary estimates show that health spending in the Nation reached $192.4 billion in 1978, or an average of $863 per person (table 1). The 1978 health bill was up 13.2 percent over the previous year, a slightly lower increase than the 14.2 percent increase registered for 1977.

Preliminary estimates

Health care spending in 1978 represented an amount equal to 9.1 percent of a Gross National Product (GNP) that exceeded $2 trillion. This percent has been increasing steadily since the period for which the first estimates of health spending were made--1929, when the percentage was 3.5. Health expenditures reached 6.2 percent of GNP by 1965. Since 1965, total health spending has grown at an average of 12.2 percent per year while the economy as a whole has grown at a 9.0 percent annual rate. (See chart)

Chart 1

National health expenditures and percent of gross national product, selected calendar years, 1950-1978

Spending by Government programs financed 41 percent of all health care--$78 billion or $350 per capita. This was virtually the same as the share in 1977 and down very slightly from the 42 percent seen in 1975 and 1976.

Private spending, reaching $513 per capita in 1978, has been increasing at a greater rate than public spending for the past 3 years. This differential decreased in 1978, with private spending increasing 14 percent and public spending increasing 13 percent, only 1 percentage point less. Prior to 1976, public spending had increased at twice the rate as private on the average.

The growth in the major portion of health costs, personal health care, is the result of a variety of factors: population growth; changes in the use of goods and services; and changes in the kinds of goods and services being used. Although price has been considered the major contributor to expenditure growth, no accurate measure of medical care price change has been available. This year an implicit price deflator for personal health care expenditures has been developed. (See the section on concepts and definitions for a discussion of this deflator.)

By using the deflator, the relative contribution of the factors affecting the increase in personal health expenditures can be determined. As shown in table 2, between 1969 and 1978 price inflation accounted for 63 percent of the increase in expenditures; population growth accounted for 7 percent; and “intensity,” reflecting changes in use and/or composition of goods and services, accounted for the remaining 30 percent. Had there been no price growth between 1969 and 1978, personal health care expenditures in 1978 would have been $69 billion lower. (See bar graph, next page.)

Use of Health Care Dollars

The most expensive type of care and the leading category of health spending is hospital services. Such services comprised two-fifths of total health spending in 1978.

Hospital Care

The $76.0 billion spent for hospital care includes all inpatient and out-patient care in public and private hospitals and all services and supplies provided by hospitals (table 3). Expenditures for physicians' services rendered in hospitals are excluded, except for the services of those who are hospital staff.

Based on July 1 population estimates including outlying territories, armed forces and federal employees overseas, and their dependents.

Preliminary estimates.

Hospital care is one of the fastest growing expenditure categories, and the one receiving the most public attention in recent years. Spending has grown over 260 percent in the last 10 years, an average 14 percent per year. The focal point of this attention is the community hospital. Primarily non-Federal short-term general hospitals, they account for more than 80 percent of all dollars spent for hospital care. The increase in such outlays has been rapid, averaging 14.5 percent per year since 1970. Using the national hospital input price index change , 65 percent of the 1970-78 increase is due purely to inflation. Another 6 percent of the increase is related to population growth, and the remaining 29 percent is the result of increased “intensity,” greater use and/or changes in the kinds and amounts of services provided.

This “intensity” increase is reflected in a number of ways. First, the number of inpatient days has increased 8 percent since 1970 (table 9). Because the average number of days per stay has declined, it also appears that more resources per day are being utilized. For example, the number of hospital laboratory tests nearly doubled in 6 years, growing from 2.2 billion in 1972 to over 4 billion in 1977. In addition, surgical operations, which generally require more resources than medical stays, grew nearly 18 percent in that same 6-year period. The number of out-patient visits also increased dramatically in this same period--22 percent. As a result, outpatient expenses represent nearly 10 percent of the community hospital bill. To the extent that these outpatient visits provide services that would otherwise be provided on an inpatient basis, they could have a moderating effect on all overall costs. Frequently, however, they are providing services that substitute for services in a physician's office where they would be less expensive.

Based on data compiled by the American Hospital Association from the Annual Survey of Hospitals

Less than .05 percent

The growth in patient days has not kept pace with the growth in hospital beds. As a result, average occupancy rates have declined, dropping from a high of nearly 79 percent in 1969 to 74 percent in 1977--an indication that hospitals are maintaining more unused beds, with the attendant overhead costs.

Physicians' Services

The second largest expenditure item is physicians' services. Spending for these services accounted for 18 percent of all health care spending in 1978, or $35.2 billion. This amount included the cost of all services and supplies provided in physicians' offices, expenditures for services by private practitioners in hospitals and other institutions, and physician-ordered diagnostic laboratory work in independent clinical laboratories. Laboratory work both in physicians' offices and in independent laboratories amounted to over $4.2 billion in 1978.

Expenditures for physicians' services have been growing at a rapid pace. In 1965 they amounted to 8.5 billion or $43 per person; in 1978 they had jumped to $35.2 billion or $158 per person. The increasing numbers of physicians and increasing specialization of physicians have contributed to this growth. It has been suggested that physicians generate their own demand so that an increase in the supply of physicians increases the demand for their services as well. In calendar year 1975, for example, the number of office-based physicians rose 5 percent. According to one study, the growing trend toward specialization is a significant contributor to increased expenditures for physicians' services.

In addition, increased concern over liability for malpractice has no doubt contributed to the number and complexity of diagnostic tests performed, adding to the cost of physicians' services. Finally, as third parties assume the financing of a larger share of these services, there is less “discounting” of charges for persons who are less able to pay, and greater proportionate reimbursement for services.

The total volume and per capita number of physician office visits have changed very little in recent years, but the number of services provided to patients has increased rapidly. For example, the National Center for Health Statistics' Health Interview Survey shows that total physician visits remained relatively constant from 1972, when 1,016 million visits were provided to the noninstitutional population, through 1977, when 1,020 million visits were provided. Per capita visits actually decreased over this period from 5.0 to 4.8. However, during the same period, out-of-hospital laboratory tests (excluding x-rays and radiation therapy) increased from less than 900 million to over 1.5 billion--from 850 tests per 1,000 physicians visits to 1,510. The increased testing, along with the increased surgery discussed earlier, contributed substantially to growing intensity, and therefore costs of physician services.

Physicians influence health spending levels to a much greater extent than is indicated by the 19 percent share of spending devoted to their services. Physicians are the most important determinant in the process of deciding who will receive hospital care, what care shall be provided, and what the duration of care will be.

Nursing Home care

The third largest category of spending, and the fastest growing, is nursing home care. Amounting to $15.8 billion in 1978, this care is provided in skilled-nursing facilities, intermediate-care facilities, and personal-care homes with provision for nursing care. The relatively small amount of nursing home type care provided in hospitals is included with expenditures for hospital care.

Expenditures for nursing home care have experienced annual increases averaging 16 percent since 1970. Nursing home input price increases alone have risen 8 percent per year in that 8-year period. The large wage component subject to the new minimum wage law requirements along with the relatively large food and fuel components indicate that price increases will continue to be rapid in the near future. The growing size and increasing age of the elderly population also contributes to the growth of this category. In recent years, nursing home use, measured by days of care, has been growing from 4 to 6 percent annually and is not likely to abate soon.

Drugs and Drug Sundries

The aging of the population also affects the growth of expenditures for drugs and drug sundries. This category accounted for over 8 percent of health spending ($15.1 billion) in 1978 and has been increasing 7.6 percent annually since 1970. It should be pointed out that this figure represents prescription drugs, over-the-counter drugs, and medical sundries dispensed through retail channels. Expenditures for drugs dispensed in inpatient settings, through outpatient clinics, and directly by physicians are reported within those cost categories. About 56 percent of all dollars for drugs and drug sundries are estimated to be spent for prescription drugs alone.

Other

The remaining 13 percent of personal health care expenditures were for dentists, services of other health professionals, eyeglasses and orthopedic appliances, and the cost of providing care in industrial plants.

About 13 percent more, $24.5 billion, was spent for nonpersonal health care services--to cover the prepayment and administrative expense of private health insurance and public programs, for funding government public health programs, for research, and for construction of medical facilities. Expenditures for research (both biomedical and health care delivery) include only government funds for research and expenditures by research and development organizations. Research and development expenditures by drug companies and by other manufacturers, and providers of medical equipment and supplies (estimated at $1.8 billion in 1978) are not included with research expenditures but are included in the expenditure class in which the product or service falls. (See “Definitions” section for further description on nonpersonal care categories.)

Financing of Health Care

Unlike other goods and services in which the consumer pays the provider directly, health care payments are frequently handled by a financial agent--a “third party.” In 1978, more than two-thirds of the funds spent for personal health care were supplied by third parties of various kinds, principally private health insurers or public agencies acting as insurers or, in some cases, as providers of health services. The details of the payment method vary--the private health insurance organization may reimburse the provider in whole or in part for the cost of service, or the consumer is reimbursed for money he has paid out for insured services. Public agencies may employ the private insurance industry to disburse provider payments on behalf of entitled beneficiaries, or government agencies may provide health care services directly to selected groups.

Third-party Payments

In 1978 all third parties combined financed $112.6 billion of the $167.9 billion in personal health expenditures or 67 percent (table 5). All levels of government--Federal, State, and local--financed the largest portion of that amount, $65.0 billion or 39 percent of the total. Private health insurance benefit payments covered an additional 27 percent of personal health care. Care financed by private philanthropic organizations and amounts spent by industry for maintenance of inplant health services amounted to a little over 1 percent of the total.

Preliminary estimates.

Based on July 1 population estimates including outlying territories, armed forces and federal employees overseas, and their dependents.

Third-party involvement has been growing dramatically. In 1965, less than half (47 percent) of all personal health care funds were handled by third parties, contrasted with two-thirds in 1978 (table 7). The insurance share increased moderately from 23 to 27 percent over these 14 years. Public spending, on the other hand, nearly doubled--from 21 to 39 percent.

Includes all expenditures for health services and supplies other than (a) expenses for prepayment and administration; (b) government public health activities.

Includes any insurance benefits and expenses for prepayment (insurance premiums less insurance benefits).

Preliminary estimates.

Both insurance and government concentrate on hospital care and physicians services. These two third parties dominate the financing of hospital care. In 1978 they paid 90 percent (including a 1 percent contribution from philanthropy). The increase in this percentage since 1965, 82 percent, has not been dramatic, but the mix has changed: government payments increased from 39 to 54 percent of all hospital care during the period 1965-78 (table 8), but the share paid by private insurance declined from 42 to 35 percent.

Preliminary estimates.

Includes dentists' services, other professional services, drugs and drug sundries, eyeglasses and appliances, nursing-home care, and other health services.

Included in direct payments; data not available separately.

Physicians' services are not reimbursed by third parties to as great an extent as hospital care, but the overall growth since 1965 has been greater. Government payments rose from 7 to 27 percent of doctors' bills in that period; insurance benefits rose from 32 to 39 percent. All third-party payments for physicians rose from 39 to 66 percent of the total.

For the remaining personal health care services, third parties pay a smaller, but growing, proportion. Payments by government and insurance doubled from 18 to 37 percent between 1965 and 1978. This growth was primarily due to growth in government payments.

Private Health Insurance

Private insurers, including the Blue Cross-Blue Shield Associations, commercial insurance companies, and independent plans, paid benefits amounting to $45.4 billion, or 27 percent of personal health care expenditures, in 1978. Normally, the premiums collected by private health insurers exceed the amounts paid out in benefits. This allows the insurer to cover the administrative cost of paying claims, to maintain appropriate and required reserves to cover anticipated claims, and to profit, in the case of for-profit companies. The difference between the premiums and benefit payments, the “net cost,” is included in the national health expenditure estimates under “Expenditures for Prepayment and Administration.” It is not classified in personal health care. Of the total $53.0 billion in premiums collected in 1978, $45.4 billion were paid in benefits and the remaining $7.7 billion represented the “net cost.” (For a detailed discussion of the private health industry, see Private Health Insurance in 1977: An evaluation by Marjorie Smith Carroll and Ross Arnett; in a future issue of the Health Care Financing Review).

The period of the 1950's was a time of rapid expansion for private health insurance. By 1960, 21 percent of personal health care was covered by private insurance; by 1965 the share reached 23 percent. With the enactment of Medicare and Medicaid in 1965, Government expenditures began to increase significantly and the growth of the insurance share began to slow. In the last few years, it has stabilized at about 27 percent.

The impact of private health insurance has varied by type of care. Hospital care was the first type of service to be extensively covered by insurance. In 1960, private insurance covered 36 percent of hospital care expenditures. That share reached 42 percent by 1965 and has hovered around 35 percent in recent years. Extent ions of coverage beyond just surgical procedures in recent years has lead to a higher share of physicians' services being reimbursed by private insurance. This share rose from 29 percent in 1967 to 39 percent in 1978.

For all other services, insurance coverage has been extremely limited. Dental care is the only other category with any significant private insurance share; about 19 percent of dental expenditures are paid for by insurance.

Public Spending

Government-sponsored programs spent $65.0 billion and provided 39 percent of personal health care spending in 1978. All expenditures under programs established by public law are included here. Amounts spent under workers' compensation programs, for example, are counted as government expenditures, although they involve benefits paid by private insurers from premiums collected from private sources. Federal funds financed more than two-thirds of the public outlay, $46.5 billion. State and local governments provided the remaining $18.5 billion.

The two largest Government programs involved in the financing of health care are Medicare and Medicaid, which together paid $43 billion in benefits in 1978. This amount financed over one-quarter of the total expenditures and two-thirds of all public spending for personal health care. In 1977 the administration of these two programs was consolidated under a new Federal agency--the Health Care Financing Administration--in the Department of Health, Education, and Welfare.

Medicare

More than 27 million persons are enrolled under the Medicare program, 90 percent of whom are aged 65 or older. In 1978 program expenditures totaled $25.9 billion, of which $24.9 billion represented benefit payments. An average of $1,557 per person was paid in 1978 for the approximately 16 million persons receiving benefits.

The Medicare program, established under Title XVIII of the Social Security Act, became effective July 1, 1966. Initially, it was designed as a Federal insurance program to protect the elderly (those aged 65 years and older) from the high cost of obtaining adequate acute medical care. On July 1, 1973, permanently disabled workers (and their dependents) eligible for OASDHI disability benefits, and persons suffering from end-stage renal disease became eligible for Medicare benefits.

Medicare payments for hospital care, $18.3 billion, represented 73 percent of program benefit payments and paid for 24 percent of all hospital care in the Nation. Nearly all Medicare hospital benefits (98 percent) are for care in community hospitals with most of that amount for acute care. Reimbursements for physicians' services were 22 percent of Medicare payments and 16 percent of all physician revenues. Payments for long-term care such as nursing home care are only made if it is required for convalescence and only if skilled-nursing care is provided. Less than 3 percent of all nursing home expenditures were covered by this program in 1978.

Growth in total personal health care spending by Medicare was nearly 15 percent in 1978, down from 18 percent the previous year. Slight moderation in hospital costs may be a factor here, as well as a leveling off in expenditure growth which resulted from the inclusion of the new enrollment groups in 1973.

Unlike other Federal programs, Medicare is not financed solely by general revenues. The Hospital Insurance Program is financed largely through a payroll tax on employers and employees. The Supplemental Medical Insurance Program (SMI) is financed through premium payments and general revenues. The general revenue share of SMI has grown significantly from about 50 percent in 1972 to 69 percent in 1978. This growth is due to the legal restriction on premium increases. Premiums may not increase more than monthly cash retirement and survivor benefits under the Social Security programs. Since SMI benefit payments have grown faster than premium payments limited by these provisions, the Federal share required to maintain the trust fund has grown proportionately faster, as shown on the next page.

Medicaid

In 1978, Medicaid paid $18.4 billion in benefits (table 6), averaging $806 per person, on behalf of 22.8 million recipients. Expenditures were up 10 percent over 1977, somewhat less than the increase over 1976. Title XIX of the Social Security Act established a joint Federal-State program to provide medical assistance to certain categories of low-income persons. These include aged, blind, and disabled persons, or members of families with dependent children when one parent is absent, incapacitated, or unemployed. Medicaid provides medical assistance to those groups or categories of people who are eligible to receive cash assistance under one of the existing welfare programs established under the Social Security Act (Title IV-A, Aid to Families with Dependent Children (AFDC), or Title XVI, Supplemental Security Income (SSI)). The program is State-administered and provides for Federal matching grants for a portion of the cost of providing medical benefits to the categorical eligible. In addition, if the State chooses, Federal matching funds are available for medical benefits for the “medically needy”--persons in one of the qualifying categories who have incomes too high for cash assistance but not adequate to pay their medical bills. The Federal share is derived from a formula based on a State's per capita income. Currently, the Federal contribution ranges by State from 50 to 78 percent, with the national average at 56 percent.

Preliminary estimates.

Represents total expenditures from trust funds for benefits and administrative costs. Trust fund income includes premium payments paid by or on behalf of enrollees.

Includes funds paid into Medicare trust funds by States under “buy-in” agreements to cover premiums for public assistance recipients and for persons who are medically indigent.

Includes care for retirees and military dependents. Payments for services other than hospital care and other health services represent only those made under contract medical programs.

Expenditures for state and local hospitals not offset by other revenues.

Includes program spending for Maternal and Child Health; Vocational Rehabilitation medical payments; Temporary Disability Insurance medical payments; PHS and other Federal hospitals; Indian Health Services; Alcoholism, Drug Abuse and Mental Health; school health.

Medicaid payments for hospital care were $6.9 billion in 1978, 9 percent of total hospital expenditures. The program covers much more long-term, nonacute institutional care than Medicare; hospital payments include a larger portion of care in long-term care and psychiatric hospitals. In addition, 39 percent of Medicaid benefits were for nursing home expenditures. This $7.2 billion represented 46 percent of all spending and 87 percent of public spending for nursing homes in 1978. In recent years, benefits for intermediate-care facilities for the mentally retarded have been included in the Medicaid nursing home figures, accounting for 13 percent of program nursing home benefits in 1978.

Medicaid, along with Medicare, is also a major financing source for home health services. Although the level of spending for these services is relatively low, its recent and continuing growth makes it particularly noteworthy. The basic services provided by home health agencies are home visits by nurses, aides and other nonphysician health professionals. These services are considered, in part, substitutes for the more expensive institutional care. In 1972 about $280 million was spent for such home health services, about a third of which was funded by the Medicare and Medicaid programs. By 1978 the level of total expenditures had risen to about $845 million, about 80 percent of which was funded by Medicare or Medicaid. Thus, most of the growth in spending for home health agencies was financed by HCFA programs. This growth was due mainly to the increase in number of persons using such services. In 1972 home health visits were provided to about 250,000 persons under Medicare and 113,000 under Medicaid. By 1977, nearly 700,000 Medicare recipients and about 300,000 Medicaid recipients were receiving home health care.

About 8 percent of home health agency expenditures are provided by hospital-based agencies and are included in the hospital services sector of personal health care expenditures. The rest is included in “other professional services.”

Medicare and Medicaid serve a population that overlaps to some extent. Medicaid pays the Medicare Supplementary Medical Insurance premiums for more than 3 million persons. If this duplication is deducted from the combined Medicare and Medicaid populations, the number of persons eligible and/or receiving benefits under the two programs is over 47 million or one-fifth of the U.S. population.

Other

State spending for medical care for the poor who are not eligible for Medicaid or for benefits not eligible for Federal matching funds, such as abortions, is classified as “other medical public assistance.” In 1978, this spending amounted to slightly over $1 billion.

In addition the other large public contribution to health spending comes from State and local government outlays in their own hospitals. State and local governments spent $5.5 billion in 1978 after deducting other public and private spending.

The Veterans' Administration spending provided another 8 percent of public spending and the Department of Defense financed an additional 6 percent.

The category “other public expenditures for personal health care,” shown in table 5, includes a number of public programs not detailed in this report. These include maternal and child health programs, $672 million; medical payments under vocational rehabilitation, $263 million; temporary disability insurance, $77 million; Public Health Service and other Federal hospitals, $1,018 million; Indian Health Services, $321 million; and Alcohol, Drug Abuse, and Mental Health Administration, $788 million. The following table shows the relative share of public programs for selected types of services.

The growth in services reimbursed by Medicare and Medicaid has dramatically altered the nature of public spending since 1965. At that time the Federal and the State and local governments shared almost equally in spending for personal health care--with 10 and 11 percent, respectively. By 1978 the Federal portion had increased steadily to 28 percent and the State and local share had remained at 11 percent. State and local spending is the net after Federal reimbursements and grants-in-aid for various programs have been deducted. The amounts received from the Federal Government as revenue sharing funds and used for health programs is not deducted from State spending since there is not adequate information to make this adjustment. During the fiscal year ending September 1977, States used $615 million in revenue sharing funds for health care purposes, much of which is reflected in “Government public health activities.”

Combined public spending for personal health care in 1978 was 39 percent of the total or $65.0 billion. Because of the orientation of Medicare and Medicaid toward hospital care, public spending for hospital care jumped from 39 to 55 percent from 1965 to 1967. Since that time it has varied between 52 and 55 percent, standing at 54 percent in 1978. The public share of spending for physicians' services nearly tripled in the same 1965 through 1967 period and reached 27 percent in 1978.

Philanthropy and Industrial Inplant

In addition to the health care financed by private insurers and public programs, some health care is provided to industrial employees through inplant health services. Expenditures for these services, classified under “other health services,” are estimated at $1.1 billion in 1978. Private philanthropic organizations' funds for personal health care are classified by type of care and totaled $1 billion in 1978. Administrative and fund-raising expenses are classified with expenses for prepayment and administration, while philanthropic support of research and construction is included with the respective expenditure categories.

Direct Payments

The portion of personal health care expenditures not paid by third-parties is known as “direct payments” or “out-of-pocket” costs. This amount excludes the consumer payments for Medicare or private health insurance premiums, but includes deductible and coinsurance amounts. In 1978, direct payments amounted to $55.3 billion or $248 per person.

With the rapid growth in third-party financing, the direct payment share has dropped from 53 percent in 1965 to 33 percent in 1978. Thus, while total per capita spending for personal health care increased over four times in that period, direct payments per person increased only 2-1/2 times, from $101 to $248. In constant dollars the direct payment increase has been only 1.3 percent per year.

The share of expenditures borne directly by the consumer varies enormously by type of service (table 5). In 1978, consumers directly paid only 10 percent of hospital expenditures, an average of $34 per person. They averaged $54 per person, or 34 percent of physicians' expenditures. For dentists, however, the direct share was 77 percent and for drugs and drug sundries it was 84 percent. As shown in table 8, the direct payment share for hospital and physicians' services has been cut nearly in half since 1965. For all other services, however, private health insurance and public programs have not made as significant a dent in the out-of-pocket bill.

Definitions, Concepts, and Sources of Data

Estimates of national health expenditures are compiled by type of expenditure (use of funds) and channel of financing (source of funds). In most instances, the total level of the expenditures for each type of service is developed for the Nation as a whole; estimates for government spending for these services are then subtracted to derive the private contribution. In all cases the intent is to account for each dollar spent for health care and to count it only once as it moves through the complex channels that are involved in the American health care system.

Expenditures for Government Programs

All expenditures for health care that are channeled through any program established by public law are treated as a public expenditure in these estimates. Expenditures under workers' compensation programs, for example, are included with government expenditures although they involve benefits paid by private insurers from premiums that have been collected from private sources.

Funds disbursed by public programs are reported as program expenditures, including private contributions made by enrollees in the supplemental medical insurance (SMI) program under Medicare. The benefit expenditures reported in this series are not adjusted to eliminate the Medicare-Medicaid duplication due to payments made by State governments into the Medicare trust fund in the form of SMI premiums for public assistance and supplemental security income (SSI) recipients and reported as a Medicaid expenditure. This “buy-in” amount was $288 million in 1978.

Federal expenditures

Federal program expenditures are based on data reported to the Office of Management and Budget by the various Federal agencies.

Several significant differences exist, however, because of the conceptual framework on which the national health expenditure series is based. Expenditures for education and training of health professionals are excluded from national health expenditures. These Federal expenditures include, principally, direct support of health professional schools and student assistance through loans and scholarships. Training is funded for a wide variety of health professionals--including physicians, dentists, nurses, mental health and other health professionals, research personnel, and paramedical personnel. Payments by agencies for health insurance for employees are included with other private health insurance expenditures rather than as a government expenditure.

Outlays by Federal programs by the type of health care provided are based on information available from each program.

State and local government expenditures

In general, all spending by State and local government units for health care that is reimbursed neither by Federal funds as benefit payments or grants-in-aid nor by patients or their agents is treated as State and local expenditures. For State-administered programs, such as Medicaid, the figure reported is net of matching revenues from the Federal Government.

Health expenditures made by State and local governments that are financed by funds received from the Federal Government under revenue sharing are reported as a State and local expenditure, not as a Federal expenditure. No information is available on the use of such funds by specific programs.

As with Federal expenditures, payments for employee health insurance by State and local governments as employers are included under private health insurance expenditures.

The estimates of expenditures for hospital care are compiled chiefly from data on hospital finances collected by the American Hospital Association (AHA) as part of the Annual Survey of Hospitals and the monthly National Hospital Panel Survey. The data from the monthly survey is used to project levels of community hospital expenditures for periods more recent than the latest annual survey and to adjust the annual survey data to correspond to the various periods for which estimates are made.

The composite estimate represents all spending for hospital services in the Nation for both inpatient and outpatient care, including all services by hospital staff (including physicians salaried by the hospital) and spending for drugs and other supplies. Self-employed physicians' services in hospitals (surgeons, for example) are not counted as hospital expenditures. Anesthesia and x-ray services are sometimes classified as hospital care expenditures and sometimes as expenditures for physicians' services, depending on billing practices.

The focus is on outlays for hospital services rather than the cost of providing service. Therefore, total revenue data are used for community hospitals; for other types of hospitals, where revenue data are not available, total expenses are used. Certain adjustments are made in the AHA data: Additions are made to allow for a small number of hospitals not included in the national totals; small amounts for Federal grants-in-aid are deducted since they are counted as research expenditures. For Federal hospitals, figures, supplied by agencies are used.

Nursing Home Care

Expenditures for nursing home care encompass spending in all facilities or parts of facilities providing some level of nursing care. Included are all nursing homes certified by Medicare and/or Medicaid as skilled-nursing facilities, those certified by Medicaid as intermediate-care facilities for regular patients as well as solely for the mentally retarded, and all other homes providing some level of nursing care even though they are not certified under either program.

The estimates for total nursing home expenditures other than those intermediate-care facilities serving the mentally retarded are derived from data on facilities, utilization, and costs, obtained from the National Center for Health Statistics National Nursing Home Surveys and ratios of revenues to costs estimated from Internal Revenue Service reports and other sources. Estimates for years for which no data are available are based on indices of prices paid by nursing homes for labor and nonlabor resources and other indicators of utilization. The nonhospital portion of Medicaid expenditures for intermediate-care facilities for the mentally retarded is added to regular nursing home expenditures. This composite estimate represents total spending for nursing home care.

Services of Physicians, Dentists, and Other Health Professionals

Expenditures for the services of these practitioners are based primarily on data compiled from business income tax returns filed with the Internal Revenue Service. The Internal Revenue Service prepares summaries of the financial information on the return by type of business. Annual reports of these summaries are published in Statistics of Income--Business Income Tax Returns.

For physicians and dentists, total business receipts (which excludes non-practice-derived income) are totaled for sole proprietorships, partnerships, and incorporated practices. For physicians, that portion of spending for outpatient independent laboratory services billed directly to patients and not included with physicians' business receipts is added, as well as estimated expenses of nonprofit group-practice prepayment plans in providing physicians' services (to the extent that they are not duplicated in physicians' income from self-employment). Estimated receipts by physicians for life insurance exams are deducted. Physician group practices that are nonprofit corporations are included with prepayment plans as indicated above or, in some cases, with hospital expenditures where services are provided under contract to hospitals.

The salaries of physicians and dentists on the staffs of hospitals and hospital outpatient facilities are considered a component of hospital care; if they are serving in field services of the Armed Forces their salaries are included in “other health services.” Where they are separable, expenditures for the education and training of medical personnel are considered as expenditures for education and excluded from health expenditures.

Expenditures for nonprofit group-practice dental clinics are added to dentists' business receipts. No separate adjustment is necessary for dental laboratories, since all billings are assumed to be made through dentists' offices.

The Internal Revenue Service also compiles data on the income of other health professionals in private practice. These include private-duty nurses, chiropractors, and optometrists, as well as other undesignated health professionals. Estimates for home health agencies that are not hospital-based are added to the private income of other health professionals. The portions of optometrists' receipts that represent the cost of eyeglasses are deducted, since they are included under spending for eyeglasses and appliances.

Drug and Drug Sundries, Eyeglasses and Orthopedic Appliances

Expenditures in these categories include only spending for outpatient drugs and appliances and exclude those provided to hospital inpatients, nursing home patients, and through physicians' offices. The basic source of the estimates for drugs and drug sundries and for eyeglasses and appliances is the estimate of personal consumption expenditures compiled by the Bureau of Economic Analysis of the Department of Commerce as part of the National Income and Product Accounts. This estimate is adjusted to levels of expenditure represented in the 1972 Census of Retail Trade. In addition, estimated payments by workers' compensation programs are deducted (a part of which is private consumer payment in the Commerce series but treated as a public expenditure in this National Health Expenditure series). The resulting private spending figure for drugs and for appliances is combined with expenditures by public programs for these products to arrive at the total amount of expenditures for the Nation.

Other Health Services

Items of expenditure that could not be classified elsewhere are brought together in the category “other health services.” It includes, for each public program, the residual amount of expenditures not classified as a specific type of medical service. In addition, it includes (1) industrial inplant services, (2) school health services, and (3) medical activities in Federal units other than hospitals.

Expenditures for industrial in-plant services consist of private industry spending for maintaining on-site health services. School health spending is reported under the source-of-fund category of “other public expenditures for personal health care.” Expenditures for medical activities in Federal units other than hospitals are residual amounts that represent primarily the cost of maintaining military outpatient facilities (separately from hospitals) and field and ship-board medical stations.

Government Public Health Activities

The Federal portion of government public health activities consists of outlays for the organization and delivery of health services, the prevention and control of health problems, and similar health activities administered by various Federal agencies, chiefly the Department of Health, Education, and Welfare.

The State and local portion represents expenditures of all State and local health departments less intergovernment payments to the States and localities for public health activities. It excludes expenditures of other State and local government departments for air-pollution and water-pollution control, sanitation water supplies, and sewage treatment. The source of these data is Government Finances (annual statistical series) of the Bureau of the Census.

Expenses for Prepayment and Administration

Prepayment expense represents the difference between the earned premiums or subscription income of private health insurance organizations and their claims or benefit expenditures (or expenditures for providing such services in the case of organizations that provide services directly). In other words, it is the amount retained by health insurance organizations for operating expenses, additions to reserves, and profits.

The administration component includes nonpersonal health expenditures of private voluntary health organizations for health education, lobbying, fund-raising, etc. In addition, it includes administrative expenses of federally financed health programs. Such data were available for Medicare, Medicaid, and the Veterans Administration and Department of Defense contract programs for medical care.

Medical Research

Expenditures for medical research include all spending for biomedical research and research in the delivery of health services by private organizations and public agencies whose primary object is the advancement of human health. Also included are those research expenditures directly related to health that are made by other Federal agencies. Research expenditures of drug and medical supply companies are excluded since they are included in the cost of the product.

The Federal amounts are derived from agency reports. The amounts shown for State and local governments and private expenditures are based on published estimates prepared by the National Institutes of Health--primarily in the annual publication, Basic Data Relating to the National Institutes of Health.

Construction of Medical Facilities

Expenditures for construction represent “value put in place” for hospitals, nursing homes, medical clinics, and medical research facilities but not for private office buildings providing office and laboratory facilities for private practitioners. Also excluded are amounts spent for construction of water-treatment or sewage-treatment plants and Federal grants for these purposes.

The data for “value put in place” for construction of publicly and privately owned medical facilities in each year are taken from Department of Commerce reports.

Implicit Price Deflator for Health Expenditures

This year for the first time, an implicit price deflator for health is available. The medical care price index of the Consumer Price Index (CPI), which has frequently been used to deflate health expenditures, is not appropriate for several reasons. First, the weights in the CPI are determined on the basis of consumer spending for each category. For example, hospital care, which is financed primarily by third-parties, has a weight of less than 20 percent in the CPI for medical care, even though it represents 45 percent of personal health care expenditures. Since the consumer share of each category varies, the index is inaccurate to the extent that price increases among categories vary. Second, the kinds of goods or services measured within each category also reflect consumer spending. Thus, physicians' surgical services, which are quite heavily financed by third parties, are not represented in the physicians' fee index of the CPI to the same extent they are represented in overall expenditures for physicians' services. Third, the CPI is a Laspeyres composite price index which keeps the weights assigned to the various prices constant over time. To the extent that changes in utilization vary among categories, the CPI is an ineffective measure of price change.

The deflator, a Paasche price index, is the result of piecewise price adjustment of the components of personal health care expenditures. Conceptually, the composite deflator is superior to the CPI, since the weights are derived from total spending for each category; the weights are adjusted each year to reflect changes in use; and, where possible, the price measures used are more reflective of overall spending in a category. The expenditure categories deflated, and the respective price proxies, are shown on the following page.

Estimates of benefits paid and the prepayment expense of private health insurance organizations are derived from the data series on the financial experience of private health insurance organizations compiled by the Health Care Financing Administration.
