Developing patient-facing roles for medical physicists to advance patient care

Patients frequently view radiation therapy as a technically complex and convoluted medical specialty. Misconceptions about radiation and confusion surrounding treatment procedures often result in patients having questions about the technical aspects of their care (1). When these concerns are not adequately addressed, either in person or online (2), these circumstances can lead to patient-related distress which has been shown to negatively impact outcomes following radiation therapy (3).

Medical physicists are uniquely qualified to address patient questions and concerns related to the technical aspects of their care. The current training paradigm for medical physicists produces analytical patient-care professionals with a propensity for problem solving. This training also instills a comprehensive understanding of the science and technology that dominate the fields of diagnostic imaging and radiation therapy. By expanding this education and knowledge to also include formal training in patient communication (4), medical physicists can further advance their scope of practice to include new patient-facing responsibilities (5).

At our institution, the Physics Direct Patient Care Initiative was created to evaluate the impact of patient-facing roles for medical physicists. As part of the protocol, medical physicists establish independent professional relationships with patients to oversee and communicate all of the technical aspects related to the patient’s care (6). After attending a dedicated patient communication training program, a series of clinical trials were initiated where medical physicists had two sessions with patients for physicist-patient consults to describe the role of a medical physicist, explain the treatment planning and delivery process, review the patient’s treatment plan, and answer all technical questions. Initial studies related to the initiative have shown that physicist-patient consults are associated with low patient anxiety and high patient satisfaction (6), patient questions can be categorized to help others prepare for addressing patient concerns (7), and an accelerated patient communication training program for medical physicists can increase the participants’ level of confidence across multiple communication categories (8). As research in this field continues, medical physicists have an opportunity to reevaluate their contributions to radiation oncology, assess the needs of patients, and establish new roles and responsibilities to advance patient care.
