Analysis of the Belgian RTT workforce and estimation of workforce needs for the near future

Radiation Therapists (RTTs) are crucial in delivering Radiotherapy (RT) to cancer patients. The advancements in RT technology and the increasing cancer incidence have heightened the demand for RTTs, necessitating strategic workforce planning at the national level. This study aims to identify and estimate current and future RTT workforce in Belgium.

A self-designed survey based on a literature review, validated and distributed to all RTT managers in Belgium, requested information about departmental activities, current workforce, and future needs to allow for the calculation of workforce needs. Data were analysed using descriptive statistics for closed-ended and thematic analysis for open-ended responses.

In 2022, Belgium had 544 RTTs or 461 full-time equivalents (FTE) RTTs. Even though 448.5 FTE RTTs would be enough to comply with Belgium law requirements, RTT managers argued that 509 FTE RTTs is more realistic to meet demands of current practice. The study identified a 20% workforce deficit, indicating a shortfall of approximately 113 RTTs. Additionally, 20% growth in annual RT treatments exacerbates this deficiency, implying a need for around 574 FTE RTTs by 2025.

This study provides a comprehensive analysis of the Belgian RTTs workforce. While the current number of RTTs meets legal requirements, it falls short of the ideal FTEs required to meet current practice. By 2025, the demand for RTTs is expected to surpass 2022's needs, highlighting a critical workforce shortage. Further research is necessary to identify ways to close this workforce gap.

The Belgian regulations governing RT departments must be updated to reflect current practices. The findings of this study are essential for planning the RTTs workforce in Belgium, ensuring adequate staffing to meet future RT demands.
