A Delphi study of current practices and establishing consensus regarding assessment of fitness to drive among patients with brain tumours

Purpose: Evaluating fitness to drive among patients with brain tumours remains a challenge for clinicians. Due to difficulties in conducting prospective driving studies in this patient cohort, a Delphi study was performed to formulate new driving guidelines for patients with brain tumours. Methods: The survey questions, which were designed by utilising Australian driving guidelines and previous Delphi studies, established panelists’ expertise, and then used a 9-point Likert scale to formulate new driving guidelines. An expert group of panelists comprising medical oncologists, radiation oncologists, neurosurgeons, and neurologists were chosen based on membership to professional societies with validation in part one of the survey. Two rounds of anonymised surveys were performed using REDCap for data entry, and a novel automated methodology on R for data analysis. Results: 46 statements regarding fitness to drive were developed. Among the 37 surveys distributed, there were 26 responses (70.3% response rate) from round one, and 17 responses (65.4% response rate) for round two. Among the 46 statements, 19 (41.3%) achieved consensus. In addition to establishing a framework for assessing patients, there was notable consensus agreement for stable imaging required as part of evaluation and the need for continual reassessment. Conclusion: Despite clinicians being aware of driving guidelines, determining fitness to drive among patients with brain tumours remains a challenge. This Delphi study identified consensus agreement for the need for stable imaging, and continually reassessing fitness to drive. These novel findings could be translated into future driving guidelines and consensus statements can be integrated into clinical practice.
