Highlights

  • 130 participants enrolled into a lung stereotactic ablative body radiotherapy eLearning programme.

  • The eLearning programme consisted of seven training modules covering stereotactic topics.

  • eLearning participation showed a 14% improvement in knowledge based on testing before and after eLearning intervention.

  • For most participants there was a significant (P < 0.001) improvement in confidence after completing each training module.

Abstract

Aims

In technically advanced multicentre clinical trials, participating centres can benefit from a credentialing programme before participating in the trial. Education of staff in participating centres is an important aspect of a successful clinical trial. In the multicentre study of fractionated versus single fraction stereotactic ablative body radiotherapy in lung oligometastases (TROG 13.01), knowledge transfer of stereotactic ablative body radiotherapy techniques to the local multidisciplinary team is intended as part of the credentialing process. In this study, a web-based learning platform was developed to provide education and training for the multidisciplinary trial teams at geographically distinct sites.

Materials and methods

A web-based platform using eLearning software consisting of seven training modules was developed. These modules were based on extracranial stereotactic theory covering the following discrete modules: Clinical background; Planning technique and evaluation; Planning optimisation; Four-dimensional computed tomography simulation; Patient-specific quality assurance; Cone beam computed tomography and image guidance; Contouring organs at risk. Radiation oncologists, medical physicists and radiation therapists from hospitals in Australia and New Zealand were invited to participate in this study. Each discipline was enrolled into a subset of modules (core modules) and was evaluated before and after completing each module. The effectiveness of the eLearning training will be evaluated based on (i) knowledge retention after participation in the web-based training and (ii) confidence evaluation after participation in the training. Evaluation consisted of a knowledge test and confidence evaluation using a Likert scale.

Results

In total, 130 participants were enrolled into the eLearning programme: 81 radiation therapists (62.3%), 27 medical physicists (20.8%) and 22 radiation oncologists (16.9%). There was an average absolute improvement of 14% in test score (P < 0.001) after learning. This score improvement compared with initial testing was also observed in the long-term testing (>4 weeks) after completing the modules (P < 0.001). For most there was significant increase in confidence (P < 0.001) after completing all the modules.

Introduction

Quality assurance during technically demanding radiotherapy trials has been shown by such trials as the TROG 98.02 phase III [1] and the RTOG 9704 [2] to critically affect cancer outcomes and the likelihood of trial success. As more multicentre clinical trials of advanced technologies open, a high-quality credentialing programme can ensure that treatment techniques are delivered according to protocol. The importance of the credentialing process has been highlighted in the Gynecologic Oncologic Group Protocol 165 trial, which found that major protocol deviations were observed only in centres that did not receive credentialing compared with those centres that were credentialed [3].

In establishing a radiotherapy credentialing programme, a challenge for the trial management committee is to provide a clear protocol that can be interpreted in the same way by all participating hospitals. Co-operative clinical trials groups, such as the Radiation Therapy Oncology Group and European Organisation for Research and Treatment of Cancer, have published recommendations [4], [5] for establishing credentialing requirements. These recommendations for radiotherapy-based clinical trials emphasise the participation in a dosimetry audit as well as a planning dry-run exercise. For stereotactic ablative body radiotherapy (SABR), the challenge is the various levels of SABR experience in participating centres. Provision of education and training can therefore appeal to institutions where SABR is new. By mandating participation in a knowledge credentialing process, a minimum educational benchmark is ensured.

Web-based training is attractive because it can be easily delivered to large groups of participants in a relatively cost-effective way. The effectiveness of web-based training in a multicentre clinical trial setting has been reported by Foroudi et al. [6]. This report described the effectiveness of an eLearning platform that was part of the credentialing programme for the multicentre study of online adaptive radiotherapy (TROG 10.01) [7]. However, the effectiveness of such an education platform for a multidisciplinary audience has yet to be presented. Based on the success of this platform, our study will report on the effectiveness of web-based training in a trial of lung stereotactic radiotherapy. The TROG 13.01/ALTG 13.001 SAFRON II trial is a randomised phase II multicentre clinical trial comparing the toxicity of a single 28 Gy in one fraction regimen of SABR versus a 48 Gy in four fraction regimen (clinicaltrials.gov NCT01965223) [8]. The study target accrual is 84 patients in order to investigate the primary end point, which is the number of participants experiencing less than or equal to 5% toxicity at 12 months after treatment. As part of the development phase of this multicentre study, training and education for the multidisciplinary team (radiation oncologist, medical physicist and radiation therapist) was a component of the participating centre credentialing process.

The aims of this study were to investigate among radiation oncologists, medical physicists and radiation therapists: (i) knowledge retention of stereotactic body radiotherapy principles and (ii) individual self-confidence rating before and after eLearning intervention.

Participants

Institutional ethics board approval was received for this study. Radiation oncologists, medical physicists and radiation therapists from Australian and New Zealand centres who expressed interest in the SAFRON II study were invited to participate in the eLearning programme. A full protocol was provided to all participants who agreed with the eLearning programme.

Module Development

Training modules for lung SABR radiotherapy were developed to cover all aspects of the clinical pathway of a patient undergoing SABR

Results

In total, 130 participants from over 12 hospitals across Australia and New Zealand consented to participate in the eLearning study. Of this total, 104 (80%) participants completed their core modules, the remaining number started but did not complete various percentages of the entire curriculum. The predominant profession to enrol into the programme was radiation therapists (62.3%), followed by medical physicists (20.8%) and then by radiation oncologists (16.9%). There was a relatively even

Discussion

Protocol non-compliance can lead to inferior patient outcomes. Some notable examples include the study by Peters et al. [1] in head and neck malignancies; lack of protocol compliance translated to a 20% absolute overall survival detriment at 2 years. Similarly, in a multicentre phase III study of pancreatic cancer (RTOG 9704) [2], protocol compliance was associated with a statistically significant improvement in median survival from 1.46 years to 1.76 years, being a stronger predictor of

Conclusion

A web-based eLearning platform can be successfully completed in a multicentre clinical trial setting for SABR treatment of the lung. This knowledge credentialing process is feasible and shows knowledge improvement for the radiation oncologists, medical physicists and radiation therapists who participated. The improvement in knowledge is observed at both short-term and long-term testing. Confidence level was significantly improved in all core modules completed.
