Many who might have elected a career in nursing in the past are today choosing other careers. The result is a severe nationwide shortage of nursing personnel, as recently documented by the federal Health Resources and Services Administration. Virginia is no exception to this skilled workforce shortage.
In response, the 2000 Virginia General Assembly amended the code of Virginia by adding a section relating to nursing workforce information. Specifically, this section of the Code reads as follows:
54.1-3012.1 Nursing workforce information.
A. With such funds as are appropriated for this purpose, the Board shall collect, store, and make available nursing workforce information regarding the various categories of nurses certified, licensed or registered under the provisions of this chapter. This information to be collected on nurses shall include, but not be limited to: (i) demographic data; (ii) level of education; (iii) employment status; (iv) employment setting such as in a hospital, physician's office or nursing home; (v) geographic location of employment; (vi) type of nursing position or area of specialty; and (vii) number of hours worked per week. Such information shall be collected and updated biennially, and shall be made available to interested parties only in aggregate form. Information which could identify individual nurses shall not be released in any form or manner.
The implementation of the provisions of this act was made by the Virginia Board of Nursing through a contract with the Virginia Tech Center for Survey Research (CSR) to design and conduct a mail survey that would be representative of all types of Virginia resident nurses who are registered, certified, or licensed by the Virginia Board of Nursing. Included are Certified Nurse Aides (CNAs), Licensed Practical Nurses (LPNs), Registered Nurses (RNs), Clinical Nurse Specialists (CNSs), and Licensed Nurse Practitioners (LNPs) -- hereafter referred to in aggregate as "nurses" or "nursing workforce".
These critical data, covering all aspects of the Virginia nursing workforce as specified in the act of the Virginia General Assembly, comprise the first set of current detailed information to begin to better understand the dynamics of the shortages in the nursing workforce in the Commonwealth. This information provides significant detail on the "supply side" of the "supply-demand equation".
The survey instrument used for this study was developed by the Virginia Tech Center for Survey Research in collaboration with staff members of the Virginia Board of Nursing. Design of the instrument content was focused particularly on those informational components expressly delineated by the amended Code of Virginia, section 54.1-3012.1. Instrument content was also informed by the review of other contemporary surveys of the nursing workforce, and particularly by the survey questions employed in the Nurse Information System (NIS) of the National Council of State Boards of Nursing.
From the outset, the survey instrument was also constructed under the premise that it would be applicable to all types of nurses and nurse aides. Additionally, there were no item content constraints as to work setting specificity. The instrument was also constructed in a manner to be inclusive of those who are not presently in the workforce as well as for those who are presently working outside of the nursing field.
The draft mock-up was then subject to several iterations of changes in item content and wording as recommended by various staff persons at the Virginia Board of Nursing. The revised version of the survey form was then circulated to five RNs, one LNP, and two LPNs for review and additional suggestions. This resulted in the addition of response categories to several items and some additional minor wording changes. This final version was approved by the Executive Director of the Board of Nursing prior to production.
The final approved copy was designed with generous blank space in order to appear easily and quickly answerable. It was printed in a four-page single-fold booklet. It was produced on off-white paper and photo-reduced to a 7" x 9 ½" size in order to enhance the visual appeal and provide a "polished" official presentation to the survey recipient. To further enhance respondent perceptions of importance, the Virginia State seal and the sponsorship by the Department of Health Professions, Board of Nursing, were prominently displayed at the top of the first page of the instrument. Survey forms were consecutively numbered so that returns could be linked back to the mailing list and respondents could be eliminated from receiving subsequent mailings. A copy of the survey instrument text is shown in Appendix A, and an actual survey instrument also accompanies this report.
The Board of Nursing specified that only in-state residents should be included in the study. After excluding those persons with out-of-state or incomplete residential addresses, the Board of Nursing registry included 116,368 individuals. Each of these persons was assigned by the Board of Nursing to one of five discrete nurse categories based on Board registry information. The number of nurses in the five categories was highly variable: from only 404 CNSs to as many as 62,431 RNs (after removal of RNs who were also in the registry as holding a Virginia license as an LNP or registration as a CNS). Therefore a stratified disproportionate random sampling design was implemented in order to adequately represent each of the five types of nurses with an active license, registration or certification.
Moreover, there was substantial regional variation in the number or resident nurses. Consequently, in order to assure proportional representation by region, the 116,386 nurses were classified into one of six Virginia regions, based on regional definitions used by the Virginia Hospital and Healthcare Association (VHHA). For each type of nurse, the same proportion was sampled for survey inclusion in each of the six Virginia regions.
The actual proportion of registrants sampled varied by nurse group. The sampling proportion within nurse group was determined in a manner so as to provide reasonable assurance that the sampling error associated with responses for each of the five nurse groups would be less than ±5 percent.
Overall, 5.2 percent of all Virginia resident nurses were surveyed. The proportion varied from 100 percent of the 404 holding registration as a CNS, to a random 3 percent of the 62,431 RNs. A total of 6,076 individuals were surveyed. Subsequently, 18 cases were identified as duplicate sample members who held both a license as an LNP and registration as a CNS. These cases were removed from the LNP sample count, and remained in the CNS sample count. Consequently, the final sample size surveyed was 6,058. Full documentation of the sampling design and sample sizes, by type of nurse and by region, is shown in Table 1.
The research design called for a first wave mailing of the survey to the complete sample, followed by a reminder postcard one week later. A second wave mailing of another survey form was subsequently mailed to non-respondents approximately seven weeks later. In order to distinguish this mail from routine bulk mail, all mailings utilized a first class "live" stamp. Most of the first wave was mailed on Friday, June 8, 2001, with remaining surveys mailed on Monday, June 11. This was followed by a reminder postcard mailed on Monday, June 18. Returned surveys were logged in daily, and a second mailing of the survey form was sent to all first wave non-respondents on Friday, July 27, 2001.

3 Excludes those also holding a Virginia license as LNP or registration as CNS.
Each survey mailing was accompanied by a postage-paid return
envelope and a cover letter from the Executive Director of the Virginia
Board of Nursing. For the 1,358 CNAs, the salutation was "Dear Virginia
Nurse Aide"; with "Dear Virginia Nurse" for all others in the sample.
The same salutation variation was retained on the letter accompanying
the second wave survey mailing. The text of the cover letter was identical
to all. Copies of the first wave cover letter, the reminder postcard,
and the second wave cover letter are shown in Appendix B.
All surveys returned from the post office with forwarding addresses were remailed to the new addresses. Additionally, 266 survey forms were returned as undeliverable by the post office and six were returned with the addressee being identified as deceased. After eliminating duplicate returns, a total of 4,405 completed surveys were received. Excluding those that were undeliverable or deceased, the effective response rate was 76.1 percent. The overall response rate ranged from a low of 55.6 percent for Certified Nurse Aides to a high of 86.1 percent of surveys returned by the Clinical Nurse Specialists. The total number of returns for each nurse group, the corresponding response rate, and the associated sampling error for each nurse group are shown in Table 2.
Data entry was undertaken using the Sawtooth Ci3 program which precludes out-of-range entry errors. Once data entry was completed, a simple random sample of 20 percent of survey forms were selected and re-entered by a different data-entry staff person at the CSR. The two independent entries were compared and a keystroke accuracy rate of greater than 99.5

percent was ascertained. Any keystroke errors for the quality control random sample were checked against the original survey response form and the error corrected on the data file. All open-ended responses were checked for spelling accuracy and consistency in wording and abbreviations. Those open-ended "other" responses that were obviously similar to a listed coded category were reassigned to that category in the post-processing and editing phase.
Compilation of Respondent Data
Each of the five discrete nurse groups are uniquely different from the others and hence, it is likely unreasonable that responses could be combined across these groups. Indeed, given the different sampling ratios for each group, and the variations in response rates, aggregation of responses from different nurse groups would first require calculation of a multiplier weight to adjust for these differences.
Therefore, for the present report all statistical calculations are made separately for each of the five nurse groups. Compilation of percentage distributions for responses to all close-ended survey questions, for each of the five nurse groups, is shown in Appendix D. Listing of responses to open-ended survey items are presented in Appendix E.
Data Uses and Storage
The data file containing individual responses is provided to the Board of Nursing for possible additional in-house analyses. However, these individual response data will not be released by the CSR to any other entity. This policy is to assure: (1) the guarantee of confidentiality made to individual respondents will not be breached; and (2) the Virginia General Assembly legislative requirement that data shall be provided only in aggregate form and shall not be released in any way which could allow identification of individuals.
This "raw" data file is provided on a diskette which accompanies this report. This is an ASCII data file. The associated codebook is shown in Appendix C as well as included on the diskette. Also included is an SPSS data file with all individual data for close-ended items as well as variable and response category labels and the responses to open-ended items.
The descriptive summary data tabulations, as displayed in Appendix D of this report, are also included in electronic version. This will be transmitted as an electronic file which can be directly loaded onto the Board of Nursing's web site.
The CSR will maintain backup files of the data, the SPSS data file and the program used for tabulating the results for a period of no less than one year. Release of this backup information will only be made to the Virginia Board of Nursing.
The Virginia Tech Center for Survey Research encourages and appreciates acknowledgement of its role in projects. However, in such cases there should be a disclaimer of Center for Survey Research responsibility for interpretations or discussion of implications of results.
