The findings show that there are significant differences in hourly earnings by work level for many of the healthcare occupations examined in this study.

U.S. hospitals1 employ about 5.8 million workers2 in a complex work environment, providing intensive medical care to treat acute illnesses or injuries for about 35 million patients annually.3 In 2008, hospitals took in revenues of $1.7 trillion.4 Considering the size of the hospital industry in the United States and the projected employment growth of healthcare occupations over the next decade,5 an analysis of current wages of hospital healthcare workers is timely. This article uses the 2008 National Compensation Survey (NCS) earnings estimates to discuss earnings differences between full-time workers in civilian hospitals and those in the civilian sector as a whole.6 Then, the article analyzes the earnings of full-time civilian hospital healthcare workers by occupation and work level. The article finds that there are significant differences in hourly earnings by work level for many of the healthcare occupations studied.

U.S. hospitals employ workers in a wide variety of occupations that are found in other industries, including such occupations as computer support specialists, human resources managers, accountants and auditors, and building and grounds cleaning and maintenance workers; hospitals also employ workers, in occupations specific to the medical field, such as medical and clinical laboratory technologists, radiation therapists, and diagnostic medical sonographers. Within many of the healthcare occupations, there is a wide range of skills required and differences in on-the-job duties and responsibilities among workers. Also, workers may work full time or part time and be unionized, and there may be institutional differences in the types of jobs offered and pay practices between private industry and State and local government employers. Occupational earnings reflect these factors. Furthermore, earnings are only part of the total compensation of workers; benefits represent about 32 percent of total compensation costs in private hospitals and about 35 percent of such costs in State and local government hospitals.7 The value of the benefits package offered may affect the wages workers are willing to accept.

The National Compensation Survey (NCS), which provides comprehensive measures of occupational earnings, compensation cost trends, the incidence of benefits, and benefit plan provisions, publishes a national annual bulletin on the occupational earnings of civilian8 workers--defined by the NCS as those who work in private industry and in State and local government establishments. The NCS has published national data on the occupational earnings of hospital workers annually since the 2006 survey year.9 The most recent data, for the 2008 survey year, include hourly earnings estimates for all workers, full-time workers, and part-time workers who are employed by hospitals in the civilian sector as a whole, those in private industry, and those in State and local government, by work level.10 Relative standard errors are available for each estimate.11

Earnings of full-time civilian healthcare workers: hospitals and all civilian industries

Full-time healthcare practitioners and technical occupations--professions such as physicians and surgeons, registered nurses, medical technologists and technicians, and therapists--are found throughout the civilian sector, most commonly in hospitals, ambulatory care centers, doctors’ offices, community centers, schools, nursing homes, and health units in business establishments. As table 1 shows, healthcare practitioners and technical workers in hospitals earned an average of $29.07 per hour, while those in the civilian sector as a whole earned $30.23 per hour.

Full-time physicians and surgeons as a group earned an average of $76.46 per hour in the civilian economy as a whole. By contrast, full-time physicians and surgeons in hospitals earned an average of $46.99 per hour, with a median of only $27.56. These seemingly incongruous findings merit a closer look at the data.

Earnings of full-time physicians and surgeons and registered nurses, in hospitals

NCS raw data on physicians and surgeons' full-time earnings in hospitals were clustered in two areas--at about $24 per hour and $86 per hour--rather than spread in a normal (centralized) distribution around the mean. What is a likely reason for this? In civilian hospitals, the average full-time hourly earnings of general internists was $30.89 per hour--significantly lower than for general internists in the civilian sector as a whole ($74.16). The relatively low earnings of full-time general internists employed in civilian hospitals are due in part to the fact that this occupation is heavily populated by residents--medical doctors in their first year of clinical practice, who are working towards a State licensure, or those working towards certification in a medical specialty.12 Residents typically work long hours compared with other full-time hospital physicians and surgeons. The number of hours worked by hospital residents is discussed more in the section of this article on work levels.

The Nation’s 2,542,760 registered nurses,13 represent the largest healthcare occupation--more than a third of all healthcare professionals.14 About 60 percent of registered nurses work in hospitals.15 Registered nurses who work full time in hospitals earned $31.93 per hour--not significantly different than the average earned by their counterparts the civilian economy as a whole ($31.54). Like physicians and surgeons, registered nurses are not a homogenous group in terms of their work environment, duties and responsibilities, and the skills and formal education they are required to have and use on the job.16 Considering the complexity of the hospital environment, richer data can provide more useful information on the earnings of healthcare workers. The NCS provides these data.

Earnings by work level among full-time healthcare workers in civilian hospitals

The National Compensation Survey evaluates each surveyed job for work level, which is a classification of duties and responsibilities performed by the worker.17 Work levels are used in pay-grade systems to determine wages and salaries--typically, the higher the work level, the higher the pay grade.18 As a worker attains more experience on the job or receives additional training or education, the worker can take on greater responsibilities and increase the complexity or difficulty of duties performed on the job--in turn, he or she may be evaluated at a higher work level.

In the NCS, occupations are evaluated for work levels 1 through 15. In the civilian sector, occupations such as chief executives are typically found at the highest work levels; elementary and middle school teachers and paralegals and legal assistants are generally in the mid-range; and waiters and waitresses, crossing guards, and taxi drivers and chauffeurs are at the lowest work levels. Some occupations are found in a wide range of work levels. For example, accountants and auditors worked at levels 5 through 13, and engineers worked at levels 5 through 15.

For the 2008 data on civilian hospital healthcare workers, there was no occupation with publishable estimates above level 13, and no occupation covered all 13 levels. The distribution of occupational estimates by level in table 2 shows that there is generally a correlation of earnings with work level--the higher the work level, the higher the hourly earnings. Many occupations encompass a range of duties and responsibilities, and earnings tend to reflect this. In this sense, earnings data by occupational work level offer more information than occupational earnings data alone.

The value of earnings data by work level is perhaps best illustrated for the earnings of registered nurses. A person using the title “registered nurse” must be registered in the State in which he or she works and must have a recognized degree in nursing.19 Advanced practice registered nurses (APRNs) include nurse practitioners, certified nurse-midwives, clinical nurse specialists, and certified registered nurse anesthetists; APRNs hold a post-graduate degree and specialized certification. Greater levels of education make it possible for registered nurses to take on greater on-the-job duties and responsibilities--thus, to work at higher work levels and earn higher pay rates.

Formal training and education aside, more years of experience on the job also makes it possible for registered nurses to assume greater duties and responsibilities. Entry-level registered nurses provide care such as administering prescribed drugs, recording case histories, and taking blood pressure, pulse, and temperature readings. Nurses at higher levels consult with attending physicians to reevaluate medical treatment and may conduct established clinical procedures and provide specialized nursing care--for example, for heart and vascular disease patients. Some nurses may also supervise others on staff to ensure appropriate care for each patient. Certain hospital settings, such as intensive care units, operating and recovery rooms, emergency rooms, childbirth labor and delivery sections, and outpatient units, require specialized knowledge in addition to the formal education required for basic nursing.20

The NCS does not collect demographic data on surveyed workers, such as years of education completed, professional degrees achieved, or years of job experience. However, by assessing the work-level of the job--the actual duties performed and the responsibilities borne by the worker--the earnings estimates by work level take into account the de facto results of education, experience, and any other qualities of the worker. Considering all of these factors, it is not surprising that earnings and work levels of registered nurses vary widely. Full-time registered nurses in civilian hospitals earned, on average, $31.93 per hour, with a range of $24.06 at level 6 to $44.03 at level 11.

The average earnings of civilian hospital physicians and surgeons are also made clearer using work-level data. Full-time hospital physicians and surgeons earned an average of $46.99 per hour, ranging from $21.84 at level 9 (typically residents) to $88.36 at level 13 (typically surgeons and specialists). Level-9 hospital physicians and surgeons worked an average of 46.2 hours per week, for weekly earnings of $1,008. By contrast, level-13 hospital physicians and surgeons worked an average of 40 hours per week, for weekly earnings of $3,534.

Full-time hospital workers in healthcare support occupations earned an average of $13.34 per hour, ranging from $9.91 at level 1 to $21.41 at level 7. Hourly earnings ranged from $12.68 per hour for nursing aides, orderlies, and attendants to $19.70 per hour for physical therapist assistants. Healthcare support occupations generally showed less variation in earnings by work level than healthcare practitioner and technical occupations.

Table 3 lists the hourly earnings of full-time healthcare workers in civilian hospitals at the lowest and highest publishable work levels.21 The occupations selected for this table are those in which there was a significant earnings difference between the highest and lowest publishable work levels. This table is included to show that earnings estimates by work level give greater information than earnings estimates by occupation alone.

The release of the 2008 National Compensation Survey occupational earnings data on workers in hospitals is the third annual presentation of such data, which add greater detail to an already rich source of data. Occupational earnings by work level, a measure unique to the NCS, reveals a wide range in earnings for several healthcare occupations in civilian hospitals. Work-level data provide particular insight into the pay of full-time physicians and surgeons and registered nurses employed by civilian hospitals (private and State and local combined). The NCS also provides earnings estimates of workers in private hospitals and in State and local government hospitals separately, including those who work part time (a topic that warrants further study.)22 BLS plans to release the 2009 NCS national earnings data in a summer 2010 publication.

End Notes

1 The term hospitals is used throughout the article to denote hospital employers within the scope of the National Compensation Survey (NCS). The NCS collects wage data on workers in hospitals defined under NAICS code 622000, which includes general medical and surgical hospitals, psychiatric and substance abuse hospitals, and specialty hospitals. Under the NCS, Federal government, military, and prison hospitals are excluded.

2 Hospitals (NAICS code 622000) employed 5,782,200 employees in August 2009, according to the BLS Current Employment Statistics survey. This figure includes employment in total private hospitals, State government hospitals, and local government hospitals. See Employment and Earnings, November 2009, table B-12, “Employees on Nonfarm Payrolls by Detailed Industry,” pp. 91, 93, on the Internet at http://www.bls.gov/opub/ee/empearn200911.pdf.

The American Hospital Association (AHA) defines community hospitals as “all nonfederal, short-term general, and other special hospitals. Other special hospitals include obstetrics and gynecology; eye, ear, nose, and throat; rehabilitation; orthopedic; and other individually described specialty services. Community hospitals include academic medical centers or other teaching hospitals if they are nonfederal short-term hospitals. Excluded are hospitals not accessible by the general public, such as prison hospitals or college infirmaries.” AHA 2008 data show that there are 5,010 community hospitals and 447 nonfederal psychiatric hospitals, for a total of 5,457 hospitals that, in general terms, approximate the NCS scope and definition of hospital employers.

6 Differences in earnings between healthcare workers in private industry and those in State and local government hospitals, and differences in earnings between full-time and part-time hospital healthcare workers are surely grounds for additional study; however, this article focuses on the earnings of full-time healthcare workers in civilian hospitals.
