Abstract

Introduction: Cerebral metastases are a common problem and pose complex treatment decisions, with reference to local control of treated lesions, prevention of new brain metastases, and toxicity of available treatments. At the 2007 Congress of Neurological Surgeons (CNS) Annual Meeting, a novel active learning process, called Integrated Medical LearningSM, was used to better understand contemporary practice patterns and to monitor the success of education about these critical treatment decisions. Methods: CNS members received an electronically distributed premeeting survey and educational materials about single and multiple cerebral metastasis treatment; practice patterns were elicited. At the Annual Meeting, 496 surgeons were polled using handheld devices before and after surgical and radiation oncology expert presentations. Surgeons who had answered premeeting surveys received a second, postmeeting questionnaire. Results: In the premeeting questionnaire (N = 214), higher current volume of practice, Tumor Section membership, and academic practice predicted more correct answers (P < 0.05 for all). Fifty five percent favored routine whole brain radiotherapy (WBRT) after metastasis resection. Thirty four percent 'most often' used radiosurgery to the resection bed; these respondents cited 'cognitive changes' in justifying WBRT omission. At the meeting, expert presentations were followed by audience shifts toward adjuvant WBRT after resection (P = 0.01) or radiosurgery (P < 0.001) - topics for which class I evidence was discussed. There was no shift in preference for surgery or radiosurgery (P = 0.24) or multiple metastasis treatment (P = 0.8) - topics for which clear class I evidence was not presented. Postmeeting questionnaires showed retained knowledge among meeting attendees. Conclusions: Using IML, we were able to study baseline knowledge and practice patterns for an important neuro-oncological treatment decision. Evidence suggested expert presentations were effective in changing audience opinion when relevant class I evidence was presented, and that knowledge was retained postmeeting.
