Executive Summary The 2018 Radiation Therapy Staffing and Workplace Survey was emailed in early June 2018 to 1,541 managers of U.S. radiation therapy facilities. At the close of the survey in July 2018, a total of 138 completed questionnaires had been submitted, resulting in a response rate of 9.0% The sample size of 138 yields a margin of error for overall percentages of a maximum ± 8.3% at the 95% confidence interval. To keep this report brief, responses to open-ended questions were not included, but are available upon request. Staffing of Facilities The mean number of budgeted full-time equivalents (FTEs) across all facilities was: 7.7 for radiation therapy. 2.5 for medical dosimetry. An estimation of the overall percentages of unfilled positions was calculated using the number of budgeted FTEs along with figures on vacant and recruiting positions. In radiation therapy, an estimated 3.2% of FTE positions are unfilled. In medical dosimetry, an estimated 2.4% of FTE positions are unfilled. Overall mean percentages of unfilled positions, calculated by combining the figures from both therapy and dosimetry, were highest in the Pacific region (7.2%) and lowest in New England (0.0%). Overall, the percent of unfilled positions combing both disciplines was 2.9%. The survey also tracks longitudinal changes in staffing levels in radiation therapy and medical dosimetry. The number of FTE radiation therapists budgeted at each facility rose by 0.4 from 7.3 to 7.7 between 2016, when the last Radiation Therapy Staffing Survey was conducted, and 2018. Overall, the number of FTE therapists budgeted per facility has increased by 1.7 from 6.0 in 2004 to 7.7 in 2018. The number of FTE medical dosimetrists budgeted at each facility rose by 0.3, from 2.2 in 2016 to 2.5 in 2018. The estimated vacancy rate for FTE positions in therapy rose by 0.3%, from 2.9% in 2016 to 3.2% in 2018. This marks the second time in a row estimated vacancy rates have risen. The estimated vacancy rate for FTE positions in medical dosimetry fell by 0.9%, from 3.5% in 2016 to 2.4% in 2018. This continues a downward trend in vacancy rates for medical dosimetry positions that began in 2012. Facility Demographics Urban facilities represented the largest share (53.3%) of respondents; 31.4% were suburban, and the remaining 15.3% were rural. The average respondent to the survey works in a facility that offers 16.2 services in radiation therapy and related fields. The most commonly offered services are: CT/simulation (98.5% of facilities). Intensity-modulated radiation therapy (IMRT) (97.0% of facilities). Cone-beam CT (CBCT) (92.5% of facilities). The least commonly offered services are: Hyperthermia (3.0% of facilities). Proton therapy (5.3% of facilities). Dynamic adaptive radiation therapy (15.8% of facilities). When asked which, if any, services they plan to expand, 82.0% said they plan to add additional LINAC therapy units, 27.0% plan to add real-time surface tracking, and 24.3% plan to add adaptive planning. According to the responses provided, the average facility treats 53.4 patients each day and uses 2.5 linear accelerators. Personnel Demographics The average respondent works at a facility that schedules 2.4 therapists and 1.1 dosimetrist per linear accelerator. On average, there is 1.0 hour per day when only one therapist is scheduled per linear accelerator. 1 2018 ASRT. All rights reserved. Radiation Therapy Staffing and Workplace Survey

Calculation of Percent Vacancy Rates The estimated proportion of unfilled positions for a given specialty for the population of U.S. hospitalbased radiology facilities is calculated as: (mean number of vacant and recruiting FTEs per facility) / (mean number of budgeted FTEs per facility) * 100 For example, in radiation therapy the mean vacant and recruiting FTE positions per facility is equal to 0.25. When divided by the mean budgeted FTE of 7.7, this yields a proportion of unfilled FTE positions of 0.032. Multiplying by 100 to give the percent value, and then rounding to the nearest tenth gives the percent vacancy rate for radiation therapy of 3.2%. Note that only combinations that included both the number of budgeted FTEs and the number of vacant and recruiting FTEs were used in the calculation of vacancy rates. Outliers Numeric variables were analyzed for non-representative outliers with cross-tabulated scatter plots and box plots. By conventional definition, data that were 1.5 times greater than the third quartile were designated an outlier and excluded from the analysis. 2 2018 ASRT. All rights reserved.

Appendix A. Scatterplots Below are scatterplots that demonstrate the observed relationship between selected variables from the survey. Please note that these scatterplots do not necessarily demonstrate any causal relation. They merely show how the given factors measured in the survey vary from each other. In each instance below, one variable is treated as independent (charted on the x-axis) and another is treated as dependent (charted on the y-axis). The points on the chart represent each of the observed data points from the survey. The diagonal line running across the chart represents the best-fit straight line through the observed data points. This is derived from the regression equation in the lower left-hand corner of the chart. The r² measures the proportion of variance among the data points accounted for by the regression equation. The closer the r² is to 1, the better the line fits the data; the closer the r² is to 0, the more poorly the line fits the data. Also listed is the ratio of the variable on the x-axis to the variable on the y-axis.
