The Registered Nurse Population: Findings from the 2004 National Sample Survey of Registered Nurses

Chapter III: The Registered Nurse Population 2004

As of March 2004, an estimated 2,915,309 individuals had current licenses to practice as registered nurses (RNs) in the United States.  Approximately 2,909,357 of these RNs lived and worked in the United States. This estimate represents an increase of 7.9 percent, or 212,817 above the 2,696,540 estimated number of RNs living and working in the United States in the year 2000.  Though this change is greater than the 5.4 percent increase seen across the last survey years (1996 to 2000) it is one of the lowest increases since the inception of the NSSRN.  By comparison, the highest increase in the RN population was experienced between 1992 and 1996 when the total number of RNs increased by an estimated 14.2 percent or 319,058 (from 2,239,816 to 2,558,874).  The number of RNs working outside the United States declined from 18,131 RNs in 2000 to 5,952 RNs in 2004.

The data in this report focus on the 2,909,357 RNs located in the United States.  RNs are considered to be located in the United States if they were employed in nursing in one of the 50 States and the District of Columbia or, if not employed in nursing, were residents of the United States.  Of the 2,909,357 RNs located in this country, 83.2 percent or 2,421,351 were employed in nursing (see Appendix A, Table 1). This estimate of the number employed in nursing is an increase of 219,538 RNs (10.0 percent) over the estimated 2,201,813 RNs employed in nursing in 2000. 

Age

The aging of the RN workforce in the United States has continued.  As of 2004, the average age of the total RN population (including those who are retired and not employed in nursing) was estimated to be 46.8 years.  This is the highest average age since the inception of the survey, more than 1 year older than the average age estimated in 2000 (45.2 years) and more than 2 years older than the average age estimate in 1996 (44.3 years).

The aging RN workforce reflects fewer young nurses entering the RN population, large cohorts of the RN population moving into their 50s and 60s, and older graduates from initial nursing education programs entering the RN population.  In 2004, only 8.0 percent of the RN population was under the age of 30, a decrease from 9.0 percent in 2000 and 25.1 percent in 1980.  At the same time, in 2004, 41.1 percent of RNs were 50 years of age or older, a dramatic increase from 33.0 percent in 2000 and 25.1 percent in 1980 (see Appendix A, Table 1).  The increase in the number of older nurses who returned to the workforce in response to the higher salaries and reported shortages may have contributed to the trend.

The average age at graduation for recent RN graduates appears to be slightly lower than in 2000. The average age at graduation for RNs during the 5 years prior to the survey was 29.6 years for the 2004 survey compared to 30.9 years in the 2000 survey; however, RNs who graduated between 1995 and 1999 in the 2004 survey were 31.0 years of age at graduation. In 2004, the average age of nurses who graduated from initial nursing education in 1984 or earlier was 23.8 years (see Appendix A, Table 2 for statistics on age at graduation); this is similar to the 23.9 years average age at graduation in 2000.

When the distribution of age at graduation is observed by age groups, the indication that graduates from initial education programs in more recent years are younger becomes clearer. In the 2004 survey, 39.4 percent of those graduating between 2000 and 2004 were under 25 compared to 30.9 percent of RNs under age 25 who completed their initial education between 1990 and 1999. Complementing this increase in younger graduates, 29.7 percent of nurses who completed their initial education between 1990 and 1999 were in the 35 to 49 age interval, while only 21.0 percent of RNs completing their initial education programs between 2000 and 2004 were in the 35 to 49 year age interval.

The average age of RNs at graduation from initial nursing education also varied by type of program.  Graduates of diploma and associate degree programs in 2000 or later were the same age (31.8 years) and were older than graduates of bachelor’s degree or higher programs (26.3 years) during this time period. In other graduation years, graduates of associate degree programs were older than all other graduates.  Across survey years, the age of diploma graduates has steadily been increasing across graduation cohorts.  Baccalaureate degree recipients graduating after 1989 were the youngest (see Chart 10).  However, the average age at graduation is lower since 2000 among recent graduates of associate degree and bachelor’s degree programs (declining by 1.5 years and 1.2 years respectively, compared to those who graduated during the 1990s (see Appendix A, Table 2).

Gender

Men still comprise a very small percentage of the total number of RNs living and working in the United States, although their numbers have continued to grow.  In 2000, 146,902 or 5.4 percent of RNs were men.  In 2004, 5.8 percent (168,181 RNs) were male (see Appendix A, Table 1). 

Male RNs are more likely to be younger than female RNs, with 30.1 percent of male RNs under the age of 40 compared to 26.1 percent of female RNs, and 65.7 percent of male RNs under the age of 50 compared to 57.4 percent of female RNs.  The average age for male RNs was 44.6 compared to female RNs at 47.0 years of age.  Male RNs are more likely to be employed in nursing (88.4 percent) compared to female RNs (82.9 percent).   

Male and female RNs also differ with respect to the type of program in which they received their initial nursing education.  Male and female RNs differ in the proportions graduating with either a diploma or an associate degree, with males more often receiving an associate’s degree than a diploma.   Approximately 13.5 percent of male RNs graduated from diploma programs, compared with 25.9 percent of female RNs; and 52.0 percent of male RNs graduated from associate degree programs, compared with 41.6 percent of female RNs.

[D]

When the highest nursing or nursing-related educational preparation is considered, a similar pattern emerges with respect to education below the baccalaureate degree. Females were nearly twice as likely as compared to males to list a diploma as their highest nursing or nursing-related educational preparation (18.0 percent compared to 9.2 percent). Conversely, 42.6 percent of males listed an associate degree as the highest-related educational preparation, compared to 33.2 percent of female RNs.  However, more female RNs had baccalaureate degrees (34.3 percent) than male RNs (31.6 percent). The percent of male and female RNs completing master’s or doctoral programs as their highest nursing or nursing-related education were similar, 13.7 percent and 12.9 percent, respectively (see Chart 11).  

Racial/Ethnic Background

As explained in Chapter II, due to a change in definitions, caution should be used when comparing the racial/ethnic composition of the RN population to surveys prior to 2000.  In accordance with the Office of Management and Budget (OMB), the question regarding racial and ethnic background in the March 2000 survey was changed from the previous surveys.  In 2004, as in 2000, nurses were asked to identify their ethnic background and then asked to identify all races that could best describe them.  The information was aggregated to categories similar to those reported in previous years, with one additional grouping of two or more races, non-Hispanic. The 2004 and 2000 estimates for these RNs were relatively unchanged (1.4 percent and 1.2 percent, respectively). In surveys prior to 2000, nurses had to choose from one of the racial/ethnic categories presented and could not designate multiple races. 

In 2004, 10.7 percent (311,177) of all RNs identified themselves as a racial or ethnic minority in their responses to both the questions on race and ethnicity.  However, 354,475 RNs (an additional 43,298, or about 1.5 percent of all RNs) identified themselves in 2004 as a racial or ethnic minority (see Footnote 6), even if their responses were incomplete through missing race or ethnicity information.  In 2000, 12.4 percent of the RN population (333,368) was estimated to be members of minority groups.  This apparent percentage decline, even after the adjustment for minority respondents who did not provide complete race/ethnicity information, is slight and should be seen in light of the apparent absolute increase in minority RNs.  In 2004, 7.5 percent of RNs were of unspecified racial or ethnic background; in 2000, only 1.1 percent of RNs were of unspecified racial or ethnic background.  Of the 217,651 RNs in 2004 with missing values for race or ethnicity, 27.0 percent (58,859 RNs) did not specify either race or ethnicity, 13.9 percent (30,147 RNs) specified ethnicity but not race, and 52.1 percent (128,645 RNs) specified race but not ethnicity.  This increase in missing information, and the concurrent decrease in minority RNs who specified both race and ethnic demographic information, may in part reflect a change in the data retrieval practices for missing variables.[11]

Of the RN population who specified both race and ethnicity background, 4.2 percent (122,495) were Black or African American (non-Hispanic); 3.1 percent (89,976) were Asian, Native Hawaiian, or Other Pacific Islander (non-Hispanic); 1.7 percent (48,009) were Hispanic or Latino, with any race specified; and 0.3 percent (9,453) were American Indian or Alaska Native (non-Hispanic).  An estimated 1.4 percent (41,244) reported that they were two or more races and non-Hispanic (see Appendix A, Table 1). 

These minority distributions in the RN population contrast with the minority distribution of the general United States population.  In the United States population for 2004, 12.2 percent were Black or African American (non-Hispanic), 4.1 percent were Asian, Native Hawaiian, or Other Pacific Islander (non-Hispanic), 13.7 percent were Hispanic or Latino with any race specified, 0.7 percent were American Indian or Alaska Native (non-Hispanic), and 1.3 percent were of two or more races (non-Hispanic).[12]  

Similar to the 2000 survey, minority RNs were on average younger than white, non-Hispanic RNs (45.5 years of age on average versus 47.1 for White, non-Hispanic RNs).  Asian, Native Hawaiian, or Other Pacific Islander RNs were the youngest, at 43.9 years of age, followed by Hispanic or Latino RNs at 44.1 years of age on average.  Black or African American, non-Hispanic RNs were on average the oldest, at 47.2 years of age.

RNs from minority backgrounds were more likely than non-minority nurses to be employed in nursing and to work full-time.  Nearly 88 percent of non-Hispanic minority nurses and 88.0 percent of Hispanic or Latino nurses were employed in nursing, compared with 82.6 percent of White, non-Hispanic nurses.  Minority nurses employed in nursing were also more likely than non-minority nurses to be employed full-time.  The percentage of employed RNs working full-time ranged from 75.2 percent for Hispanic or Latino RNs to 81.2 percent for non-Hispanic minority RNs.  In comparison, 68.5 percent of employed non-Hispanic White RNs worked full-time. 

Most RNs in each racial/ethnic group received their initial nursing education in associate degree programs, with the exception of RNs from Asian, Native Hawaiian, or Other Pacific Islander, non-Hispanic (19.0 percent) backgrounds. RNs from American Indian or Alaska Native, non-Hispanic backgrounds were the most likely to receive their initial nursing education in associate degree programs (60.8 percent) followed by multi-racial RNs (55.1 percent), Hispanic or Latino RNs (54.5 percent), Black or African American non-Hispanic RNs (48.7 percent) and white non-Hispanic RNs (42.4 percent). White, non-Hispanic nurses were more likely than other nurses to have received their initial nursing education in diploma programs. Twenty-seven percent (26.9 percent) of white, non-Hispanic nurses were prepared for RN licensure in diploma programs compared with 14.7 percent of Hispanic or Latino RNs and 17.8 percent of nurses who were non-White non-Hispanic.  The majority (64.0 percent) of RNs from Asian, Native Hawaiian, or Other Pacific Islander, non-Hispanic backgrounds received their initial nursing education in baccalaureate programs.  It should be recognized, however, that most Philippine-trained nurses had baccalaureate education as their initial nursing preparation.

Chart 12 illustrates how racial/ethnic groups compare in terms of highest nursing or nursing-related educational preparation.  White (non-Hispanic) RNs were most likely to have a diploma as the highest educational preparation (18.9 percent).  Asian, Native Hawaiian, or Other Pacific Islanders (non-Hispanic), as well as Black or African American (non-Hispanic) RNs were more likely than either Hispanic, Latino, or White (non-Hispanic) RNs to attain at least baccalaureate preparation.  Black or African American, non-Hispanic (14.2 percent) and White, non-Hispanic nurses (13.2 percent) were the racial/ethnic groups with the highest percentages of master’s and doctoral degrees.

Education and Employment Prior to Initial Nursing Education

Individuals come to nursing through various career paths, and a significant number choose nursing after employment in other health-related fields or after receiving other post high school academic degrees.  In 2004, about 1,512,259 (52.0 percent) of all RNs had worked in other health-related occupations prior to attending their initial nursing education (see Appendix A, Table 3).  This estimate is an increase from 2000, when 37.3 percent of RNs followed the same path, although a change in question wording can account for this marked increase. In 2000 the questionnaire asked for the respondent’s employment status immediately prior to beginning initial nursing education, while the 2004 questionnaire asked for employment status at any time prior to beginning initial nursing education.  In 2004, the majority of these nurses who had previously worked did so as nurse aides (974,764 RNs or 64.5 percent), Licensed Practical Nurses/Licensed Vocational Nurses (LPN/LVNs; 364,527 RNs or 24.1 percent) or as clerks in health care settings (208,337 RNs or 13.8 percent).  The majority of RNs who were employed before entering an initial nursing education program tended to enroll in associate degree programs (797,925 RNs or 52.8 percent) to prepare for RN licensure.  In addition, 29.9 percent of RNs (451,499 RNs) who were employed in a health occupation prior to their initial nursing education received their education in baccalaureate-or-higher degree programs.

While 484,809 RNs were estimated as ever being licensed as an LPN/LVN, 120,282 were NOT employed as LPN/LVNs prior to starting their initial RN preparation program.  Some of these 120,282 may have obtained RN licenses during the period of initial RN education for related employment purposes.  In total, there were 364,527 RNs who were employed as LPNs/LVNs prior to beginning their initial nursing education.  The majority of all RNs who were once employed as LPN/LVNs (80.2 percent or 292,365 RNs) reported an associate’s degree as their initial RN education, 11.5 percent had a baccalaureate-or-higher degree (41,927 RNs; Appendix A, Table 3).  In contrast, only 47.1 percent of RNs employed as nurse aides prior to initial nursing education received an associate degree as their initial nursing education, while 33.4 percent obtained baccalaureate-or-higher degrees.

In 2004, about 16.2 percent of the RN population, or 471,603 RNs, had post-high-school academic degrees prior to entering an initial nursing education program (see Appendix A, Table 5).  This is an increase from the 2000 estimate, when 13.3 percent of the RN population had post-high-school academic degrees prior to their initial nursing education.  Over half of the 2004 RNs who had a post-high-school academic degree prior to initial nursing education had associate degrees (52.6 percent or 247,962 RNs), and half had bachelors degrees[13] (50.2 percent or 236,871 RNs; Appendix A, Table 5).  RNs with post-high-school academic degrees prior to their initial nursing education were less likely to report an associate degree as their initial nursing education than RNs who had been employed as LVN/LPNs.  Just over 80 percent (80.2 percent) of those previously employed as LVN/LPNs reported an associate degree as initial nursing education, compared to 52.6 percent of RNs with prior academic degrees.  This is virtually unchanged since 2000, when 82.1 percent of those previously employed as LVN/LPNs reported an associate degree and 53.0 percent of RNs with prior academic degrees reported an associate degree as their initial nursing education. 

Nursing Educational Preparation

The initial educational preparation for the largest proportion of RNs is the associate degree.  Forty-two percent, or 1,227,256 of the 2,909,357 RNs received their initial nursing education in an associate degree program (see Appendix A, Table 2).  Similarly, in terms of the highest level of preparation for nursing, the trend from 1980 to 2004 indicates that an increasing number of RNs receive baccalaureate and master’s degrees, even if their initial preparation for nursing was an associates degree or a diploma (see Chart 13; Appendix A, Table 10).

Of those RNs completing their initial nursing education in the period between 2000 and early 2004, 56.9 percent graduated from an associate degree program and 39.9 percent (including 1.0 percent from masters and doctoral initial programs) graduated from a baccalaureate-or-higher initial RN program; only 2.8 percent graduated from diploma programs (see Appendix A, Table 2).

RNs relied on different sources of funding to finance their initial nursing education. The three primary sources were personal resources, family resources, and federally assisted loans.  An estimated 53.0 percent of students used some personal resources, such as earnings and savings; while 48.2 percent used family assistance to help pay for tuition and fees.   Over 22 percent (22.1 percent) used federally-assisted loans as a resource.  Federal sources of support in the form of traineeships, scholarships or grants were a resource for 13.2 percent of RNs, and employer tuition and reimbursement plans were a resource for about 8.2 percent of RNs attending school.[14] Reliance on Federal resources increased with the educational level.  About 60.7 percent of master’s and doctoral degree students relied on some type of Federal support compared to about 49.0 percent of baccalaureate students, 37.1 percent of associates degree students and 16.9 percent of diploma students (see Appendix A, Table 9).

The 2004 survey indicates that the RN population is increasingly prepared with a baccalaureate, a master’s, or doctoral degree. The highest level of nursing or nursing-related preparation for an estimated 17.5 percent of RNs (510,209) is a diploma; for an estimated 33.7 percent (981,238) the highest preparation is an associate degree; for 34.2 percent (994,276) it is a baccalaureate degree; and for 13.0 percent (376,901) a master’s or doctoral degree is their highest nursing or nursing-related education (see Appendix A, Table 10).

In addition to degrees in nursing, it should be noted that some nurses have advanced degrees that are not in nursing but related to their career in nursing (see Appendix A, Tables 10 and 11).  Of the estimated 376,901 RNs with master’s or doctoral degrees in nursing or nursing-related areas, 267,963 (71.1 percent) held nursing degrees as their highest nursing or nursing-related degree.  At the master’s level of highest nursing or nursing-related education attained, 256,415 (73.1 percent) held nursing master’s degrees.  At the doctoral level of highest nursing or nursing-related education attained, 11,548 (44.2 percent) held nursing doctoral degrees.  Nurses reported attaining an additional 105,922 master’s degrees and 29,755 doctoral degrees in fields that are not related to a career in nursing.

The highest increase from 2000 to 2004 was for the number of RNs receiving a nursing or nursing-related master’s or doctorate degree (an estimated increase of 101,833 RNs or 37 percent) compared to a decrease of 91,495 nurses or 15.2 percent in the number of RNs whose highest nursing or nursing-related degree was a diploma. Also noteworthy is the 12.9 percent increase in nursing or nursing-related baccalaureates, from 880,997 to 994,276.  As illustrated by Chart 13, by 2004 the majority (52.1 percent) of RNs who earned a master’s or doctoral degree as their highest nursing or nursing-related educational preparation received a baccalaureate degree as their initial nursing education.

Over the entire period from 1980 to 2004, there was a 43.5 percent decrease (an estimated change from 903,131 RNs to 510,209) in the number whose highest level of nursing or nursing-related education was a diploma, while the number whose highest level of nursing or nursing-related education was a master’s or doctorate increased by 339 percent (from 85,860 to 376,901). Similarly, the estimated number of RNs whose highest nursing or nursing-related preparation was a baccalaureate increased by 170 percent (367,816 to 994,276) and the estimated number whose highest nursing or nursing-related preparation was an associate’s degree increased by 232 percent, from 295,318 to 981,238 RNs. 

[D]

Of the 1,227,256 RNs initially prepared in associate degree programs, 20.7 percent or an estimated 253,453 of the nurses (i.e., 8.7 percent of all RNs) obtained additional nursing or nursing-related degrees. Of the 733,377 RNs initially prepared in diploma programs, 30.2 percent or an estimated 221,608 (i.e., 7.6 percent of all RNs) obtained post-RN nursing or nursing-related degrees. In addition, of the 887,114 RNs initially prepared in baccalaureate programs, 22.1 percent or an estimated 196,494 (i.e., 6.8 percent of all RNs) subsequently received master’s or doctorate nursing or nursing-related degrees.

In terms of overall education, including nursing degrees, nursing-related degrees, and degrees that were unrelated to nursing, an estimated 391,472 RNs received master’s degrees and 40,038 RNs received doctoral degrees after becoming RNs (see Appendix A, Table 11).  Nearly 44 percent (43.8 percent) of RNs with post-RN master’s degrees that may or may not be related to nursing chose clinical practice as their field of study. Nearly 15 percent (14.5 percent) focused on supervision/administration while 13.4 percent studied education.  Post-RN doctoral degrees were frequently focused on either education (21.3 percent), research (17.7 percent), or law (11.3 percent).  In contrast, clinical practice was the focus of just 5.8 percent of post-RN doctoral degrees (see Appendix A, Table 11).

In 2004, 7.6 percent, or 220,412 RNs, were enrolled in formal education programs leading to an academic degree or a certificate.  Most of these award programs were in nursing or would enhance a career in nursing (172,150; Appendix A, Table 12).  The RNs pursuing these academic degree programs useful to a career in nursing were mostly part-time students employed full time in nursing (54.0 percent;)  Of the estimated 166,768 RNs pursing academic degrees in nursing or related to nursing, an estimated 49.1 percent (81,402 RNs) were currently pursuing baccalaureate degrees, 45.7 percent (75,879 RNs) were pursuing master’s degrees, and 5.2 percent (8,617 RNs) were pursuing doctoral degrees.  The majority of these formal nursing or nursing-related academic degree programs (138,618) were actually in nursing, while a smaller number (30,151) were in nursing-related academic programs that would enhance a career in nursing.  Of the 111,282 RNs initially prepared in associate degree programs that were enrolled in nursing or nursing-related educational programs, 71,373 RNs (64.1 percent) were pursuing baccalaureate degrees.  A smaller number are pursuing certificates in nursing or related to nursing (20,048).  An additional 23,689 RNs were pursuing formal academic education in other fields not related to enhancing a career in nursing

Advanced Practice Nurses

Increased interest in expanding the access and availability of health care services has led to particular emphasis on advanced practice registered nurses (APNs).  The APN is an umbrella term used to describe RNs who have met advanced educational and clinical practice requirements beyond the initial nursing education required of all RNs. Many States require APNs to be recognized either by a State agency or certified by a national organization such as the American Nurses Credentialing Center (ANCC) or the relevant specialty nurses association.  APNs include clinical nurse specialists, nurse anesthetists, nurse midwives and nurse practitioners.  For this study, APNs were defined as such if they reported that they were prepared as an APN in a specific specialty field.[15]   

In total, an estimated 240,460 RNs, or 8.3 percent of the RN population, were prepared for advanced practice.  This estimate represents a 22.5 percent increase from the 196,279 APNs, or 7.3 percent of RNs estimated in 2000.  Almost three in four (74.8 percent or 179,932 APNs) of the 240,460 RNs reported a master’s degree for APN educational preparation; an additional 18,631 APNs reported at least one post-master’s certificate for their APN educational preparation.  Over 70 percent of APNs (70.1 percent or 168,546 APNs) were nationally certified and 61.8 percent (148,647 APNs) were State recognized to practice in the respective State in at least one APN specialty[16] (see Appendix A, Table 13).  Others prepared as APNs may have been not actively practicing in 2004 to have required current APN credentials.

As shown in Chart 14, the majority of those who completed APN programs were prepared as nurse practitioners (NPs; 141,209 RNs) followed by clinical nurse specialists (CNSs; 72,521 RNs).  A significant portion of RNs were at least dually prepared as both NP and CNS (14,689 RNs). These two groups together, including those with dual or multiple preparations as a nurse practitioner, clinical nurse specialist, nurse midwife, and/or or nurse anesthetist, comprised over 199,000 nurses (or 82.8 percent) of all APNs.

An estimated 32,523 of those who completed APN programs were prepared as nurse anesthetists, and an estimated 13,684 APNs were prepared as nurse midwives, with 21.1 percent (2,892 APNs) of nurse midwives being prepared as both NPs and nurse midwives (see Appendix A, Table 13).

[D]

The most common specialty among those who completed APN programs was family practice (25.0 percent), followed by adult health/medical/surgical (14.3 percent), anesthesia (13.1 percent), psychiatric/mental health (8.2 percent), pediatrics (8.1 percent), and acute/critical care (6.6 percent). Among APNs with national certification, family practice was the most common specialty APNs were certified in (20.1 percent), followed by anesthesia (12.7) and adult medicine (7.1 percent) (see Appendix A, Table 14).

Nurse Practitioners

The nurse practitioner (NP) group included all RNs prepared beyond initial nursing education in a formal nurse practitioner program of at least three months.  Generally, a minimum of a master’s degree in nursing is currently required for academic achievement in advance of national certification as a new NP.

In 2004, 141,209 RNs, were prepared to practice as NPs, which included 14,689 NPs with both NP and CNS training.  This estimate reflects a 37.3 percent increase (38,380) from the 2000 to the 2004 survey.  In 2000, there were an estimated 102,829 NPs, which included 14,643 who were also prepared as CNSs.  As reported by the NPs, 77.6 percent (109,582) of APNs with formal preparation as NPs also had national NP certification. The number with State Board of Nursing recognition was 72.3 percent or 102,142 (see Appendix A, Table 13).

Since the early 1990s, master’s degrees have become almost always mandatory for new NPs.  The data show that the education of NPs takes place primarily in master’s degree programs, with 65.5 percent (92,449) of NPs reporting having completed a master’s degree program as part of their formal APN related education. This is an increase in master’s degree NP preparation from 2000 (when 62 percent did the same) and 1996 (when 46 percent of NPs had completed a master’s degree).  In addition to master’s NP training, there were others who reported having pursued post-master’s certificates as their NP preparation (14,821 or 10.5 percent).

Almost 88 percent (87.7 percent), or 123,857 of the 141,209 NPs were employed in nursing, although only 57.7 percent (81,433) of the NPs (i.e., 65.7 percent of the NPs employed in nursing) were employed with the title of nurse practitioner (see Appendix A, Table 13). The second and third most-common job titles were staff nurse (14,358 or 11.6 percent of those NPs employed in nursing) and professor/instructor (7,715 or 6.2 percent of those NPs employed in nursing), respectively.

Clinical Nurse Specialists

Clinical nurse specialists (CNSs) included those RNs who had formal preparation related to the clinical nurse specialty. Generally, a minimum of a clinical master’s degree in nursing has been required as academic achievement in advance of practicing as a CNS.

There were an estimated 72,521 RNs (2.5 percent of all RNs) prepared to practice as CNSs in 2004, including the 14,689 RNs who were prepared as both NPs and CNSs (see below).  Between 2000 and 2004, the number of CNSs increased by 5.1 percent (an additional 3,504 CNSs).  In 2000, the number of RNs trained as CNSs was 69,017, including 14,643 who were trained as both a NP and a CNS. In 2004, of all CNSs a total of 32,385 had national certification, a 2.1 percent increase over the 2000 level of 31,713 RNs.  An estimated 27,379 CNSs had State certification in 2004, a 31.2 percent increase over the 2000 estimate of 20,863 (see Appendix A, Table 13). 

The highest education of the vast majority of CNSs takes place primarily in master’s degree programs, with 93.3 percent (67,666 CNSs) reported having completed a master’s degree program for their CNS educational preparation.  An additional 3.8 percent of CNSs (2,731 CNSs) reported having post-master’s certificates and 0.3 percent (194 CNSs) reported having doctoral degrees as their CNS educational preparation.

Of all those prepared as CNSs, 85.1 percent (or 61,735 CNSs) were employed in nursing but only 16.5 percent of the prepared CNSs (11,988 and 19.4 percent of those CNSs employed in nursing) used clinical nurse specialist as their position title.  Nevertheless, there were numerous respondents who reported having a position title of CNS but who neither appeared from the respondent data to have completed an APN educational program nor otherwise reported completing at least a master’s degree in nursing.[17] Among a wide variety of other position titles that prepared CNSs hold were instructor/faculty member (16.2 percent of those employed in nursing or 10,022) and nurse practitioner (15.9 percent of those employed in nursing or 9,802).

Nurse Practitioners and Clinical Nurse Specialists

In 2004, there were 14,689 APNs with preparation as both a NP and a CNS, representing only a slight increase from the 2000 estimate of 14,643.  The majority reported to have received APN educational preparation in at least one master’s degree program (93.4 percent or 13,716 APNs); this is consistent with the master’s educational preparation requirement for CNS’s.  Others, including some of these 13,716 APNs, reportedly received APN educational preparation through one or more post-master’s certificate programs (33.9 percent or 4,973 APNs), or Doctoral degrees (2.6 percent or 377 APNs)   Nearly all were employed in nursing (93.4 percent or 13,717 APNs). Most of these nurses prepared as both NP and CNS who were employed in nursing had nurse practitioner as their position title (8,990 APNs or 61.2 percent of those prepared as both NP and CNS and 65.5 percent of those employed in nursing), followed by instructor/faculty member, (1,310 APNs or 9.6 percent of those employed in nursing) and staff nurse (1,072 APNs or 7.8 percent of those employed in nursing). Only 5.7 percent of those employed in nursing (776 APNs) reported clinical nurse specialist as their position title.

Nurse Anesthetists

Nurse anesthetists (NAs) are the third largest group of advanced practice nurses. Included in the nurse anesthetists category were all RNs with formal preparation beyond initial nursing education in which the specialty of anesthesia was studied.  Generally, a minimum of a master’s degree is currently required for academic achievement in advance of national certification as a new NA. This national certification is a prerequisite to practicing as a NA.

In 2004, 32,523 RNs (1.1 percent of all RNs) were prepared as NAs.  In 2000, there were 29,844 NAs, representing a 9.0 percent increase from 2000 to 2004.  Virtually all (30,446 or 93.6 percent) NAs had national certification and 24,168, or 74.3 percent, had State recognition in 2004 (see Appendix A, Table 13).

The majority (18,870 or 58.0 percent) of all NAs reported receiving their educational preparation in post-RN certificate/award programs.  Just over one-third (12,083 or 37.2 percent) of all nurse anesthetists reported receiving their educational preparation in master’s degree programs.  An estimated 287 NAs (or 0.9 percent) reported educational preparation through post-master’s certificate programs.  At least a master’s degree is currently required to become a new NA.  Almost all NAs, 89.6 percent (29,150 NAs), were employed in nursing, with 26,116 NAs (80.3 percent of all prepared NAs) in positions where the job title was nurse anesthetist.   Other job titles included staff nurse (1,142 or 3.9 percent of those employed in nursing) and instructor/faculty member (331 NAs or 1.1 percent of those employed in nursing).  NAs who also had formal preparation as a CNS or NP were more likely to be employed with the title nurse anesthetist than either the titles of clinical nurse specialist or nurse practitioner. Many of the rest of those who completed NA programs may be employed in other positions that do not require certification in their specialty.

Nurse Midwives

Among the APNs, there are fewer nurse midwives (NMs) prepared or employed in this specialty than in the other three groups.[18]   To assure that NMs were appropriately classified, several screening steps were taken via responses to the survey questionnaire.  The formal education beyond initial nursing education had to be at least 9-months in length.  A second screen was needed for the relatively large proportion of RNs in the sample who indicated they had formal preparation as NMs and were initially foreign educated.  Such nurses usually need additional education to qualify for certification in this country.  Generally, a minimum of a master’s degree in nursing is currently required for academic achievement in advance of national certification as a new NM.  This national certification is a prerequisite to practicing as a NM.  After these screening steps were taken, the several hundred RNs who reported NM preparation was ultimately reduced to a corps of 175 who were considered prepared as APNs.

In 2004, there were 13,684 nurses formally prepared as NMs (0.5 percent of all RNs), including 2,892 who had preparation as both NPs and NMs.  This estimate, though based on a relatively small sample, represents a 48.2 percent increase in formal NM preparation from 2000, when 9,232 RNs were trained as NMs. Virtually all (93.7 percent or 12,820 ) of RNs trained as NMs had national certification as NMs and three-quarters (75.2 percent or 10,296) had State Board of Nursing recognition.

The majority of NMs (7,733 or 56.5 percent) reported receiving a master’s degree for their educational preparation, while 792 NMs (or 5.8 percent) reported receiving a post-master’s certificate and 5,053 NMs (36.9 percent) reported receiving a post-RN certificate. Almost all NMs (89.3 percent or 12,217 NMs) were employed in nursing; with 7,037 NMs (or 57.6 percent of those employed in nursing and 51.4 percent of all NMs) employed with the position title of nurse midwife.  Other common job titles included staff nurse (1,636 or 13.4 percent of those employed in nursing) and nurse practitioner (1,131 or 9.3 percent of NMs employed in nursing). Over 10 percent (10.7 percent) were not employed in nursing. NMs who also had formal preparation as a clinical nurse specialist or nurse practitioner were more likely to be employed in the job title of nurse midwife than either the titles of clinical nurse specialist or nurse practitioner.   Many of the rest of those who completed NM programs may be employed in other positions that do not require certification in their specialty or may be retired from practice as an NM.

Nurse Practitioners and Nurse Midwives

In 2004, there were 2,892 RNs (less than 1 percent of all RNs) who were prepared as both nurse practitioners and nurse midwives. Comparable information is not available from the 2000 NSSRN as there were not enough observations to make reliable estimates.  The largest group reported receiving their APN educational preparation in at least one master’s degree programs (45.2 percent or 1,307 NM/NPs), with additional nurses reporting APN educational preparation in at least one post-RN certificate program (33.2 percent or 960 NM/NPs) or post-master’s certificate program (536 NM/NPs or 18.5 percent).  Most were employed in nursing (80.4 percent or 2,326 NM/NPs) but only 29.9 percent of the prepared NM/NPs and 37.2 percent of those employed in nursing used nurse midwife as their position title (865 NM/NPs).  Other common titles were nurse practitioner (29.4 percent of those employed in nursing or 684 NM/NPs) followed by staff nurse (9.0 percent of those employed in nursing or 209 NM/NPs).

Non-White, Hispanic, or Latino Advanced Practice Nurses

Only 8.0 percent (19,325 RNs) of APNs were from racial/ethnic minority backgrounds (that is, non-White non-Hispanic, Hispanic, or Latino APNs of any race).  Non-White, Hispanic, or Latino nurses were most likely to be found among NPs (8.9 percent or 12,529 NPs).  In addition, non-White non-Hispanic, Hispanic, or Latino APNs of any race comprised 7.8 percent (2,538 NAs) of all NAs, 7.6 percent of NMs (1,040 NMs), and 6.3 percent of CNSs (4,547 CNSs).

Registered Nurses in the Workforce

In 2004, 83.2 percent of the RN population, or an estimated 2,421,351 RNs, were employed in nursing. This estimate represents a 10.0 percent increase since 2000 (when 2,201,813 or 81.7 percent of RNs were employed in nursing).  Although RNs can be found in all sectors of the health care system, the predominant employment setting remains the hospital, employing 1,360,847 or 56.2 percent of all RNs. The next largest group was ambulatory care settings, with 11.5 percent or 277,774 RNs.  Ambulatory care settings include physician-based practices, nurse based practices, and health maintenance organizations.  The next largest group was composed of an estimated 259,911 (10.7 percent) who worked in public/community health settings, including State or local health departments, community based home-health agencies, various types of community health centers, student health services, and occupational health services.  The fourth largest employer of RNs in 2004 was nursing homes/extended care facilities, which employed a total of 153,172 (6.3 percent) of all RNs employed in nursing. The remainder of employed nurses worked in diverse settings such as nursing education (2.6 percent), school health agencies (3.2 percent), and insurance claims/benefits (1.8 percent; Appendix A, Table 16).  Over 4 percent (4.3 percent) worked in settings categorized as “other”, composed of RNs working in correctional facilities, clinical research, home-based self-employment, private-duty nursing, call-center/telephone triage, and pharmaceuticals/medical-devices settings.

The percent of RNs employed in hospitals decreased slightly between 2000 and 2004, declining from 59.1 percent to 56.2 percent.  However, the actual number of RNs employed in hospitals increased by 4.7 percent, from 1,300,323 RNs in 2000 to 1,360,847 in 2004. This is a somewhat greater rate than the 2 percent increase from 1996 to 2000. Ambulatory care showed the greatest gain in RN employment from 2000 to 2004, with a 32.7 percent increase in RNs reporting employment in ambulatory care settings (from 209,324 to 277,774 RNs).  Some respondents may have had difficulty in distinguishing between ambulatory in a hospital setting versus ambulatory care outside a hospital setting such as: a clinic within a hospital, an ambulatory surgical center in a hospital or run by a hospital off-site, an ambulatory center nearby a hospital, a doctor’s private office within a hospital, and a doctor’s office nearby a hospital.

Over one quarter (25.1 percent) of all employed RNs (608,940), could not specify one type of patient with whom they worked, as they worked with multiple patient types. The majority of employed RNs who could specify a patient type that they, or their unit, cared for reported providing general adult care (513,834 or 21.2 percent), followed by pediatric care (176,698 or 7.3 percent) and cardiovascular care (171,219 or 7.1 percent; Appendix A, Table 17). Comparisons cannot be made with the 2000 NSSRN due to a change in the scope of the question to include all employed nurses, instead of nurses only employed in hospital inpatient or outpatient units. Of all employed RNs, 1,584,615 RNs (or 65.4 percent) reported spending more than 50 percent of their time in direct patient care, although 81.9 percent of employed RNs (1,984,224 RNs) spent at least some time (1 percent or more) in direct patient care. 

RNs employed in hospitals were asked to report the function in which they spent 50 percent or more of their time. Over 19 percent (19.3 percent) either could not or did not report a dominant function or reported “other” as the dominant function. Over two-thirds of RNs employed in hospitals (70.6 percent) reported spending more than 50 percent of their time in direct patient care, as illustrated by Chart 15.  Just over 5 percent (5.3 percent or 71,696 RNs) of hospital employed RNs reported spending more than 50 percent of their time in supervisory capacities and 2.5 percent (33,446 RNs) reported spending more than 50 percent of their time in administration.  However, 89.0 percent of all hospital employed RNs (1,211,632 RNs) reported spending at least some time (1 percent or more) in direct patient care.

[D]

As shown in Chart 16, inpatient bed units are where the majority of hospital employed nurses spend more than half their direct patient care time.  Among nurses who provided direct patient care services and reported the type of work unit where they spent more than half their patient care time, 53.7 percent reported working in inpatient bed units, similar to 2000 when 53.7 percent of RNs reported working in these units.  In 2004, 382,331 RNs reported working in general/specialty inpatient bed units; in 2000, 369,832 RNs reported working in these units, an increase of 3.4 percent.  Hospital-employed RNs working in outpatient departments experienced the greatest increase at 76.7 percent, from 69,707 in 2000 to 123,166 in 2004.  Hospital-employed RNs working in critical care or step down units increased 18.6 percent, from 272,074 RNs in 2000 to 322,740 RNs in 2004 (see Appendix A, Table 18).  Comparisons between the results of the 2000 and 2004 NSSRN surveys with respect to this issue must be interpreted with caution as there was a high number of hospital-based RNs who did not specify a work unit in 2000 (8 percent) relative to 1.3 percent of RNs reporting the same in 2004.   In addition to those unknowns without any response by the nurse, other responses did not provide an individual unit for the nominal list of specific units of Table 18.  However, in 2000, an additional 4.0 percent reported no specific area or some other specific area, in 2004, 4.5 percent of these hospital nurses providing direct patient care reported working in multiple units, no specific area, or other specific area.

Characteristics within Employment Setting

An estimated 29.7 percent or 720,283 of the 2,421,351 RNs employed in nursing were employed in nursing part-time.  In general, family status made a difference in whether nurses were employed full-time or part-time.  Employed married nurses with children, particularly those with children under the age of six, were more likely than other employed nurses to be employed on a part-time basis.  Overall, nearly 30 percent (29.8 percent) of the 2,421,351 employed RNs were working on a part-time basis.  However, slightly over 45 percent (45.4 percent) of employed married nurses with children younger than 6 worked part-time. Married nurses with children under 6 years of age represented 13.8 percent of all employed nurses (see Appendix A, Table 6).  In addition, these married nurses with children under 6 years of age were 10.7 percent of all RNs employed full-time in nursing as well as 7.5 percent of all employed RNs.

The employment status (i.e., full-time or part-time employment) of nurses varied according to the employment setting.  The highest percentage of part-time employees was found among RNs working in school health (37.6 percent of all RNs employed in school  health) and ambulatory care settings (34.4 percent of all RNs employed in ambulatory care).  The lowest percentage of part-time workers was found among nurses working in the insurance/claims/benefits field (12.5 percent of all RNs employed in this setting) and policy/planning/licensing/regulatory agencies (14.8 percent or all RNs employed in this setting; Appendix A, Table 19). 

In 2004, after excluding the hours of work information of those nurses with any on-call hours, the average scheduled work hours per year for full-time nursing positions, including paid vacations, holidays, and sick leave was 2,160 hours; for part-time nursing positions it was 873 hours (see Appendix A, Table 19).  Full-time nurses worked an average of 7.5 hours of overtime per week, while part-time nurses worked an average of 5.6 hours of overtime (see Appendix A, Table 20). Due to a difference in data collection practices, overtime hours cannot be accurately compared with the data collected in 2000[19].

Nurses in all employment settings tended to work more hours than they were scheduled.  However, the greatest amount of overtime for full-time nurses were in nursing education (8.5 hours per week).  The least amount of weekly overtime hours for full-time nurses was found in the occupational health (5.7 hours) and ambulatory care settings (5.3 hours).  For part-time nurses, there were not enough data points for a reliable analysis (see Appendix A, Table 20).  For full-time employed RNs with overtime, 32.5 percent, or 2.4 of their average weekly 7.5 overtime hours, were mandatory.  Staff nurses worked fewer hours of overtime and a slightly smaller proportion of this overtime was mandatory than for all other RNs.  This finding may be partly due to the differences between hourly and salaried nurses, the latter of whom may be required to work, or believed they are required to work, additional hours per week as part of their job duties and base salary.  For full-time staff nurses, 31.7 percent of their average weekly 7.5 hours of overtime were mandatory; for all other RNs, 35.5 percent of their 7.5 average weekly hours of overtime were mandatory (see Appendix A, Table 21).   This finding held true for staff nurses in hospitals, where the average amount of weekly overtime for staff nurses was 7.5 hours compared to 7.9 hours for non-staff nurses. Additionally, for a greater percent of non-staff nurses employed in hospitals, compared with staff nurses employed in hospitals, overtime was mandatory (39.4 percent for non-staff nurses versus 29.4 percent for staff nurses).

As indicated in earlier surveys, younger nurses were more likely than older nurses to be employed in hospitals.  In 2004, the average age of the hospital nurse was 43.4, 2 years less than the average age of 45.4 for all employed RNs.  Nurses in occupational health had the highest average age at 50.8 years (see Chart 17).  Across all settings, staff nurses were on average younger than non-staff nurses, 43.6 years of age on average versus 48.0 years of age.  This finding held true of nurses employed in hospitals, where staff nurses were 42.1 years of age on average versus 47.2 years of age for non-staff nurses.

[D]

Over three-fourths (77.6 percent) of employed RNs under the age of 30 worked in hospitals.  In contrast, less than half (46.2 percent) of employed RNs over the age of 50 worked in hospitals (see Appendix A, Table 22).

In most employment settings, the majority of nurses had an associate or baccalaureate degree as their highest nursing or nursing-related educational preparation (see Chart 18 and Appendix A, Table 23). Seventy-six percent of the nurses working in hospitals had an associate (37.7 percent) or baccalaureate degree (38.3 percent).  Nursing homes and extended care facilities were less likely than other patient care service settings to have nurses with baccalaureate and higher degrees.  Less than a quarter (24.1 percent) of nurses employed in nursing home/extended care facilities had baccalaureate degrees, while these settings drew 68.4 percent of their nurses from among those whose highest preparation was that of a diploma (21.5 percent) or associate degree (46.9 percent).  The majority of those in nursing education (52.9 percent) had a master’s or doctoral degree. Nursing education had the largest proportion of RNs with baccalaureate degrees or higher (76.0 percent), while nursing homes/extended care facilities had the least (30.8 percent).

Registered Nurses in Nursing Faculty Positions

One issue that has received considerable attention in recent years is the shortage of nurses in faculty positions  involved with the educational preparation of registered nurses. Based on the setting and principal nursing position categories used in the 2004 NSSRN, the faculty position is being defined for those nurses with principal position titles of dean, professor or instructor involved with nursing education of RNs in diploma, associate, baccalaureate, and/or higher nursing degree program settings. It is estimated that 30,470 RNs in March 2004 were employed as nursing faculty in principal nursing positions within these RN programs settings. Of these faculty nurses, 4.8 percent were in diploma programs, 39.4 percent were in associate degree programs, and 55.8 percent were in baccalaureate and/or higher degree programs. The average age of faculty nurses was 51.6 years, but the estimated average age of faculty nurses with doctorates in nursing or a related field was 55.4 years. However, the age group with the highest percent of faculty was the 50 to 54 year age group with 24.9 percent of faculty in this age group. An additional 27.2 percent were in the age groups 40 to 50 and 5.4 percent of RNs in faculty positions were in the age group 25 to 34 years. Although only 8.0 percent of faculty nurses were in the under 40 age group, 39.4 percent were over age 55.

Base of Employment

The vast majority of employed RNs (90.2 percent or 2,184,921) were employees of the facility in which they worked.  About 5.5 percent of RNs were self-employed, and 2.3 percent worked in their principal nursing position through a temporary employment service (see Appendix A, Table 24).

Approximately 54,493 nurses were employed in their principal position through a temporary employment service in 2004, and 3,039 of these nurses were employed in both a principal and secondary nursing position through this kind of agency.  This temporary employment principal position level reflects a 37.9 percent increase in the comparable number in 2000 (39,505) and continues the increasing trend which the NSSRN first observed in 1996.  In 2004, an additional 37,263 RNs were employed by a temporary agency for a secondary position aside from their primary nursing position.  Considered together, the total number of nurses employed through temporary employment services in 2004 was 91,756, or 3.2 percent of all RNs.   RNs employed through temporary services for their primary nursing position worked an average of 35.6 hours per week. The majority of RNs employed through temporary services for secondary nursing positions (58.9 percent) worked less than 500 hours per year. 

Position Levels

Over fifty-nine percent (59.1 percent), or 1,431,053 of the 2,421,351 employed nurses in 2004 were in staff nurse positions. This category included charge nurse, float nurse, public health nurse, school nurse, travel nurse, and team leader positions (see Appendix A, Tables 25 and 26).  Although the number of staff nurses increased by 5.4 percent from 1,357,349 in 2000, their proportion of the total nurse workforce has declined from 61.6 percent in 2000 and 66.9 percent in 1988.  A total of 222,411, or 9.2 percent of employed RNs, were in head nurse or supervisory positions in 2004 and 125,011 or 5.2 percent were in administrative positions. 

Charts 19a and 19b illustrate the shifts that have occurred in the distribution of RNs by selected position titles since the late 1980s.  In addition to the decline in the percentage of employed nurses who are staff nurses, there has been a notable decline in the percentage of those with the position title of supervisor (from 5.6 percent to 3.1 percent during the period from 1988 to 2004).  At the same time, significant increases have occurred in the percentage of those with the position title of nurse practitioner, growing from 1.3 percent of employed RNs in 1988 to 3.5 percent in 2004.

[D]

The variation in educational preparation according to position title is illustrated in Charts 20a and 20b and Table 27 in Appendix A.  The majority of those with each of the following respective position titles had less than baccalaureate preparation: private duty nurse (65.8 percent), supervisor (61.6 percent), staff nurse (58.3 percent), and home health nurse (58.6 percent).  Nearly half of head nurses (47.4 percent) had less than baccalaureate preparation.  In Chart 20b, about 50 percent of those reporting principal positions as a CNS do not also report having at least a master’s degree, which is usually required in most States to fully practice as a CNS.  See also footnote 17 for past acknowledgment of this perceived inconsistency in reporting of CNS education and position title.

Functions During Usual Workweek

Overall, the aggregate percent of time RNs spent in direct patient care was 60 percent in 2004, with significant percents of overall time spent in supervision (10.8 percent) and administration (8.3 percent).  (See Chart 21).  These are slight reductions from 2000 for two of these functions, where the direct patient care percentage of time was 63 percent and administration was 11 percent.

In 2004, an estimated 65.4 percent of RNs (1,584,615) employed in nursing spent at least 50 percent of their usual workweek in direct patient care activities; down from the 2000 estimate of 68.6 percent of RNs spending at least 50 percent of their workweek in direct patient care, and down from the 1996 estimate of 66.9 percent of all RNs spending their workweek in this manner.  Nearly half of RNs employed in nursing, 49.8 percent (1,205,389) spent at least 75 percent of their time in direct patient care activities (see Appendix A, Table 28). Nurses with less than a master’s degree averaged 60.8 to 64.5 percent of their usual workweek in direct patient care activities, and from 10.6 to 11.4 percent of their workweek on supervisory activities (see Appendix A, Table 29).   Nurses with master’s degrees averaged 44.5 percent of their time in direct patient care, 15.6 percent of their time in administration, and 11.4 percent in teaching.  Nurses with doctorates averaged 16.5 percent of their time in direct patient care, 27.7 percent of their time in teaching, and 23.4 percent in administration.  Doctorally prepared nurses were the only group that spent significant
