5 Executive Summary Introduction The Indiana State Department of Health and the Indiana Professional Licensing Agency developed a collaborative partnership to collect data through the licensing process to better understand the health professions workforce within the state. Beginning in 2004, physician assistants were asked to participate in voluntary surveys when renewing their licenses every two years. The purpose of this report is to summarize the participants responses to the survey items. The responses provide a detailed description of the physician assistant workforce in the state of Indiana to aid in the development of policies and programs to recruit and retain these health professionals where they are needed in Indiana. Methods Items in the re-licensure survey included demographics and characteristics of the respondent s primary position. The location of a respondent s physician assistant training program, as well as the level of education received, were also collected. This report focuses on those physician assistants who renewed their licenses electronically and had the opportunity to complete the survey; those physician assistants whose licenses were active, valid to practice while reviewed, or on probation; who identified themselves as actively working as a physician assistant; and who held non-federal principal employment positions in Indiana. Survey Respondents Results for 2010 There were nearly twice as many female than male respondents to the 2010 physician assistant survey (63.9% female and 36.1% male). Respondents were predominantly white and non-hispanic. Nearly half of all respondents were under the age of 35, and about one-tenth were over age 55. Almost 70 percent of respondents younger than 54 years of age were female, and just over 70 percent of respondents aged 55 and older were male. Over two-thirds of respondents (71.7%) reported working 40 hours or more in an average week. Almost all respondents (98.7%) stated that the area in which they spent the majority of their time was direct patient care. Comparison of Survey Results from 2004, 2006, 2008, and 2010 Of the survey respondents who listed their principal position as being in the state of Indiana, nearly all (98.6% in 2004, 98.6% in 2006, 98.8% in 2008, and 99.6% in 2010) were actively working as physician assistants. Nearly one-half (44.5% in 2004, 46.8% in 2006, 47.6% in 2008, and 48.1% in 2010) of the respondents were under 35 years of age. Three-fifths of the 4

6 respondents in 2004 (56.7%), 2008 (63.7%), and 2010 (63.9%) were female. Almost all (95.7% in 2004, 93.6% in 2008, and 93.2% in 2010) of the respondents were white, non-hispanic. The questions on gender, race and ethnicity were not asked in Spanish was the most common language spoken fluently other than English (2.5% in 2004, 3.6% in 2006, 2.8% in 2008, and 2.8% in 2010). The percentage of respondents with a bachelor s degree as their highest academic credential fell from 60.2 percent (in 2006) to 55.9 percent (in 2008) to 47 percent (in 2010). Meanwhile, the percentage of respondents with a master s degree increased from 29 percent (in 2006) to 33.6 percent (in 2008) to 44.4 percent (in 2010). From 2006 to 2010, approximately half of all respondents indicated that they attended a physician assistant training program in Indiana (48.9% in 2006, 47.8% in 2008, and 56.2% in 2010). One-third (31.7% in 2006, 31.2% in 2008, and 35.1% in 2010) received physician assistant degrees from Butler University. Around 70 percent (74.9% in 2004, 69.1% in 2006, 67.9% in 2008, and 71.7% in 2010) of respondents worked 40 hours or more in an average week. The majority of respondents (88.3% in 2004, 96.4% in 2006, 93.6% in 2008, and 92.2% in 2010) worked for private-sector employers. The largest proportion of physician assistants worked under the supervision of physicians in emergency medicine, family practice/family medicine, and orthopedic surgery. Time Trends in Survey Responses The total number of physician assistants licensed in the state has risen each year since 2004 and is expected to continue growing. From 2004 to 2010, the majority of respondents have been under the age of 54. The percentage of respondents under 35 years old has grown steadily over that time period, while the percentage of respondents between 35 and 54 has decreased. Over the same time period, the majority of respondents have worked 40 hours or more per week. However, the percentage of respondents who reported working 40 hours or more per week has shown a slight decline from 2004 to Location of Physician Assistants in Indiana The most populous counties generally had the highest number of physician assistants and the highest ratio of physician assistants to population. There were 38 counties that didn t report physician assistants practicing in them, and 25 of those counties are considered rural. None of 5

7 the counties with the highest number of physician assistants are considered rural. The counties with the highest number of physician assistants also tended to have the highest number of practicing physicians. Conclusion Respondents have been predominantly white, non-hispanic females since Nearly half of respondents were under age 35. The majority of respondents under 54 were female while the majority of respondents over 54 were male. The physician assistant workforce is undergoing a transition from a male-dominated profession to a female-dominated one. Additionally, the percentage of respondents under age 35 has increased while the percentage of respondents between 35 and 54 years old has decreased since This could indicate that physician assistants are working in Indiana immediately after completing their training, but are moving to different states after gaining some experience in the field. The most populous counties in Indiana had the highest number of physician assistants and the highest ratio of physician assistant to population. These counties also had the highest number and ratio of practicing physicians. There were 38 Indiana counties without any practicing physician assistants, 25 of which are considered rural. 6

8 Chapter 1: Introduction Having an accurate understanding of the personal and professional characteristics of physician assistants licensed in Indiana is critical to develop and manage effective programs that recruit and retain these professionals where they are most needed in the state. Quality data about physician assistants in Indiana also will help policymakers and other stakeholders make better-informed decisions. The purpose of this report is to provide these data. The findings from this report may be used to identify physician assistants shortage areas, develop more effective recruitment and retention strategies, and plan additional locations for training physician assistants within the state. The Indiana State Department of Health (ISDH) and the Indiana Professional Licensing Agency (IPLA) collaborated in implementing the 2010 Indiana Physician Assistant Re-licensure Survey. All physician assistants who renewed their licenses online were asked to complete a voluntary questionnaire. This report summarizes the results of the 2010 Indiana Physician Assistant Re-licensure Survey. Methods The data used to generate this report was extracted from the 2010 Indiana Physician Assistant Relicensure Survey dataset collected by the ISDH and the physician assistant license dataset maintained by the IPLA. The 2010 Indiana Physician Assistant Re-licensure Survey instrument included questions on current work status, principal practice location, principal position, activities performed in the principal practice location, major specialty of the supervising physician, principal practice setting, average hours worked, current education level, and demographic information. A copy of the 2010 Indiana Physician Assistants Re-licensure Survey instrument is included in Appendix 1. The data provided by the IPLA included date of birth for all licensed physician assistants who were practicing in Indiana at the time of the survey. The datasets were merged in order to match the respondents approximate age to his or her survey responses. The datasets were merged by matching the license number of each physician assistant using SAS 9.3 and age was calculated using May 15, 2010 as a reference point since surveys were completed from April of 2010 through June of The merged dataset was then used to filter the records to include only the respondents that met the inclusion criteria. 7

9 Inclusion and Exclusion Criteria The merged dataset was filtered initially to include only physician assistants with an active or probationary license and who reported an Indiana address for their primary practice location. Almost all of the respondents who reported Indiana as their primary practice location held an active Indiana license (refer to Table 1.1). Table 1.1 Current License Status License Status Number Percent Active Expired Probation Inactive Total The dataset was further refined by work status. Only those physician assistants who were currently practicing in Indiana were included in the analyses. Physician assistants who were retired, temporarily inactive, practicing outside of Indiana, or working for the government or military were excluded from the analyses. Government and military employees were excluded because this study is meant to reflect the number of physician assistants serving the community at large. A total of 461 physician assistants (91.8%) were selected for inclusion (refer to Table 1.2). Table 1.2 Current Work Status* Work Status Number Percent Excluded from Study Temporarily inactive as a PA Actively working as a PA in Federal Government Actively working as a PA in State Government Actively working as a PA in Local Government Actively working as a PA in the Military Actively working as a PA in other Total Excluded from Study Included in Study Actively working as a PA Total Included in Study Total practicing PAs in Indiana Missing 18 *These numbers represent survey respondents only. 8

10 The major focus of this report includes only those physician assistants who renewed their licenses electronically and had the opportunity to complete the questionnaire; those physician assistants whose licenses were active, valid to practice while reviewed, or on probation; who identified themselves as actively working as a physician assistant; and who held non-governmental principal employment positions in Indiana. All others were generally excluded from the results shown in this report. Weighting for County Level Data A key component of identifying potential health profession shortage areas is determining the number of existing professionals in each county. The estimated number of physician assistants in each county was calculated by summing the number of respondents in each county of principal practice location, then assigning a weight of 91.5 percent to the sum. The weight was determined by calculating the proportion of physician assistants who renewed their license electronically and responded to at least one question (n = 648) to the total number of physician assistant license renewals (n = 708) (refer to Table 1.3). Thus, the counts of the physician assistants are estimates of the actual number of physician assistants in each county and not the number of respondents in each county. The estimated number of physician assistants per county also does not necessarily reflect the total number of practicing physician assistants, but the number of physician assistants available to serve the community at large (excluding government and military employees). Table 1.3 Weighting for County Data Physician Assistant Number Percent Renewed electronically & responded to at least one question Total PA License Renewals in Data Analysis Frequency and cross-tabulation analyses were performed to describe the characteristics of the physician assistants within Indiana. The data were coded in Microsoft Excel 2007 and analyzed using SAS 9.3 and IBM SPSS Statistics 19. Graphic information system (GIS) maps were developed to illustrate the estimated number of physician assistant professionals per Indiana county, the ratio of physician assistants per 100,000 residents, and delineate rural and non-rural counties. Rural counties were defined by the United States Department of Agriculture as non-metropolitan counties and were designated by hash marks on the map. The GIS maps were designed in ArcGIS 9.3. Data from 2010 also was compared to data collected in previous surveys of physician assistants from 2004, 2006, and

11 Chapter 2: Responses to the 2010 Indiana Physician Assistant Re-licensure Survey The results in this chapter reflect the personal and professional characteristics of only those physician assistants licensed in Indiana who responded to the 2010 Indiana Physician Assistant Relicensure Survey. Caution should be taken when making generalizations about all Indiana physician assistants. The data shown may not be representative of all licensed physician assistants in Indiana since physician assistants who renewed their license by paper, as well as those who did not respond to the electronic survey are not included in these results. Each table shows the number of valid and missing responses to each survey item and the percentage of valid responses. The text describes the responses to the survey. Survey Response Rate Although only physician assistants who met the inclusion criteria were included in the analysis portion of this report, the denominator used for determining the survey response rate was based on the total number of physician assistants who renewed their licenses electronically (refer to Table 2.1). The numerator for those included in the response rate (renewed electronically and responded to at least one question) also included all physician assistants who renewed electronically, not just those who were included in the analysis. The response rate for those who had the opportunity to take the survey was 93.5 percent.

14 Education and Special Skills Table 2.8 shows the highest physician assistant credentials attained by survey respondents. Nearly half (47.0%) of respondents indicated that a bachelor s degree was their highest credentialing degree, and 44.4 percent of respondents held a master s degree. Overall, 91.4 percent of respondents held a bachelor s degree or higher. The highest degree obtained by respondents in any field is displayed in Table 2.9. There were equal numbers of respondents who held bachelor s and master s degrees (47.3% and 47.7%, respectively).

17 Practice Characteristics Table 2.12 shows the distribution of respondents across various practice settings. The majority of physician assistants worked in private practice, single specialty groups (19.4%). Additionally, 17.4 percent reported working in a hospital emergency room/emergency department (ER/ED), and 13.1 percent worked in a physician private practice-multiple specialty group. The cross-tabulations of practice setting by age group and practice setting by gender did not reveal any notable patterns; therefore, the tables for these data were not included in this report.

18 Table 2.13 displays the average number of hours worked per week performing all physician assistant activities. Nearly three-quarters of the respondents (71.7%) worked 40 hours or more each week and fewer than 12 percent worked less than 30 hours per week. As shown by the row percentages, females comprised almost 60 percent (59.2%) of the respondents who reported working 40 or more hours per week (Table 2.14). This is consistent with the distribution of female and male respondents. However, the column percentages reveal a noticeably higher percentage of male respondents (81.1%) who reported working 40 or more hours per week than female respondents who reported the same hours of work (66.1%) (Table 2.14). The column percents are shown italics. The cross-tabulation of average number of weekly hours by age group did not reveal any significant patterns; therefore, the table for these data was not included in this report.

22 Table 2.18 compares the specialties of physician assistants primary supervising physician with the number of physicians who practice within each specialty. In general, the most common specialties among physician assistants supervising physicians reflected the most common specialties among practicing physicians. Table 2.18 also includes the number of physician assistants per 100 physicians. Orthopedic surgery-trauma and emergency medicine-sports medicine were the specialties with the highest number of physician assistants per 100 physicians; each specialty had 100 physician assistants per 100 physicians (a 1:1 ratio). Obstetrics and gynecology had the fewest number of physician assistants per 100 physicians (0.5 physician assistants per 100 physicians). Of the 56 specialties in which respondents worked, 32 had less than 10 physician assistants per 100 physicians. Overall, there were just over six (6.1) physician assistants per 100 physicians. Note that the large number of missing responses from the physician report (3,368) is due to physicians practicing in specialties with no physician assistants. Physicians in these specialties were not included in this analysis. 21

26 Chapter 3: Trends in Responses from the 2004, 2006, 2008, and 2010 Physician Assistant Surveys This chapter summarizes the findings of the 2004, 2006, 2008, and 2010 Indiana physician assistant re-licensure surveys. Unless otherwise stated, the numbers are representative only of respondents and have not been adjusted to account for those who did not respond. Missing responses have been noted in each table, and only valid percentages are presented. Demographic Composition Table 3.1 shows the age distribution of respondents active in Indiana in 2004, 2006, 2008, and 2010 re-licensure periods. Nearly half of respondents were less than 35 years old in each year of the survey (44.5% in 2004, 46.8% in 2006, 47.6% in 2008, and 48.1% in 2010). Roughly one-tenth of respondents (7.4% in 2004, 8.7% in 2006, 11.3% in 2008, and 11.4% in 2010) were over 55 years old. The percentage of those less than 35 years of age as well as those in the 55 to 65 years of age group has been increasing, while the percentages in the 35 to 54 age group has been declining.

27 Gender distribution for respondents in 2004, 2008, and 2010 is shown in Table 3.2. The question on gender was not asked on the 2006 survey. Almost three-fifths of respondents in 2004 (56.7%), 2008 (63.7%), and 2010 (63.9%) were female. Based on these data, it appears the percentage of female physician assistants has been increasing.

The question on highest physician assistant degree or credential was not asked in The percentage of physician assistants possessing a bachelor s degree as their highest credential has decreased from 2006 to 2010 (60.2% in 2006, 55.9% in 2008, and 47.0% in 2010), while the percentage of physician assistants holding a master s degree as their highest credential has increased over the same time period (29.0% in 2006, 33.6% in 2008, and 44.4% in 2010). The percentage of physician assistants with an associate s degree declined slightly (6.1% in 2006, 5.8% in 2008, and 3.7% in 2010).

29 Table 3.6 shows the location of physician assistant training programs that the respondents attended. This question was not on the 2004 survey instrument. From 2006 to 2010, approximately half of all respondents indicated that they attended a physician assistant training program in Indiana (48.9% in 2006, 47.8% in 2008, and 56.2% in 2010). Respondents who attended a physician assistant training program outside of Indiana were concentrated in contiguous states (Illinois, Ohio, Kentucky, and Michigan). 28

31 Table 3.7 presents the respondents fluency in languages other than English in 2004, 2006, 2008, and In 2004, fluency in Spanish was the only information gathered on languages. Additional languages were added in subsequent surveys. Spanish was the most common language other than English spoken fluently by the respondents (2.5% in 2004, 3.6% in 2006, 2.8% in 2008, and 2.8% in 2010). The only other language with multiple speakers in each year since 2006 is French (0.8% in 2006, 1.4% in 2008, and 0.9% in 2010).

32 Professional Characteristics The activity in which respondents spent most of their professional time is shown in Table 3.8. Almost all of the respondents spent most of their professional time in direct patient care and patientcare-related activities (96.5% in 2004, 96.4% in 2006, 98.4% in 2008, 98.7% in 2010). Teaching was the second-most frequently cited activity.

Table 3.9 shows the average number of hours worked per week by all respondents. The number of respondents who worked 40 or more hours dropped from 74.9 percent in 2004 to 67.9 percent in 2008, but rose to 71.7 percent in The percentage of respondents who worked less than 20 hours per week has remained fairly constant since 2004 (3.9% in 2004, 3.6% in 2006, 3.3% in 2008, and 3.5% in 2010).

Table 3.10 describes the specialty of respondents primary supervising physicians. Emergency medicine and family practice/family medicine were the top two specialties (in order) in each year from 2004 to 2010, and orthopedic surgery was the third most common specialty in all years except 2006 (general internal medicine was the third most common specialty in 2006). Generally, the distribution of physician assistants among specialties remained constant from 2004 to

35 Principal work settings for physician assistants are shown in Table From 2004 to 2010 the two most common work settings for physician assistants were single specialty physician private practices followed by hospital ER/ED. From 2004 to 2008 the third most common work setting was solo physician private practices. The third most common work setting in 2010 was multiple specialty physician private practices.

37 Chapter 4: Trends in the Physician Assistant Workforce This chapter presents trends based on the 2004, 2006, 2008, and 2010 physician assistant surveys. Trend lines have been shown in each figure to provide an understanding of the changing supply of physician assistants. The data in Figure 4.1 refers to all licensed physician assistants in the state of Indiana (including those who renewed by mail or renewed electronically and did not complete the survey); the data represented in Figure 4.2 and Figure 4.3 only includes survey respondents from the corresponding years and do not represent the total actual number of physician assistants in Indiana. The trends presented include the total number of licensed Indiana physician assistants, the age of survey respondents, and the average hours worked per week. Figure 4.1 displays the total number of licensed physician assistants in Indiana from 2004 to Each year of the survey has seen an increasing number of licensed physician assistants in the state, and the number is expected to continue to rise in the near future. Figure 4.1 Total Number of Licensed Physician Assistants in Indiana Number of Licensed Physician Assistants Year Total Number of Licensed PAs in Indiana 36

38 Figure 4.2 shows the percentage of physician assistants who responded to the survey, by age group. There has been a decrease in the percentage of physician assistants between the ages of 35 and 54, while the percentages of physician assistants under 35 years old and between 55 and 64 years old has increased over the time period. There has been a slight decrease in the percentage of physician assistants over 65, but the numbers are so low that the trend is difficult to generalize. Figure 4.2 Age of Indiana Physician Assistants Percentage of Respondents Under and greater Year 37

39 Figure 4.3 shows the percentage of physician assistants who responded to the survey, by the average number of hours worked per week. The percentage of physician assistants working 40 hours or more per week seems to be decreasing over time; however, those respondents still account for the vast majority of physician assistants, and from 2008 to 2010 the percentage actually increased. The percentages of respondents working between 20 and 29 hours per week and 30 and 39 hours per week have been slightly increasing over the time period. Although the trend for respondents working between 30 and 39 hours per week seems to be increasing since 2004, most of that increase came between 2004 and 2006 and has been decreasing since then. The percentages of respondents working between one and nine hours per week and 10 and 19 hours per week have remained relatively stable over the time period.

40 Chapter 5: Location of Physician Assistants by County in Indiana The following maps display the estimated number of physician assistants in each county within the state of Indiana in For comparison, maps have been included that display the estimated number of physicians per county in The number of physician assistants in each county was adjusted (weighted) using the proportion of license renewals that were completed online and responded to at least one survey question (91.5%) to ensure that the data shown in these maps is representative of the number of physician assistants available to serve the population in each county. The number of physicians in each county was similarly weighted using the proportion of physician license renewals that were completed online and responded to at least one survey question (83.9%). Thus, the counts of physician assistants and physicians used in these maps are estimates of the actual number in each county, and not the number of survey respondents in each county. Data for both the physician assistant maps and the physician maps are presented at the end of the chapter in Tables 5.1 and
