Specialist Physician Roles in Ontario
A well-rounded physician is not only a medical expert and clinical decision maker, but also a communicator, collaborator, manager, health advocate, scholar and professional. The following content, from the
Royal College of Physicians and Surgeons of Canada, explores how these qualities connect to practice.

Communicator: To provide humane, high-quality care, physicians establish effective relationships with patients, other physicians, and other health professionals. Communication skills, particularly good listening, are essential for the functioning of a physician, and are necessary for obtaining information from, and conveying information to, patients and their families. These abilities are critical in eliciting patients' concerns, and expectations about their illnesses, and for assessing key factors that affect patients' health.

Collaborator: Physicians work in partnership with others who are appropriately involved in the care of individuals or specific groups of patients. It is therefore essential for physicians to be able to collaborate effectively with patients and a multidisciplinary team of expert health professionals for the provision of optimal patient care, education, and research.

Manager: Physicians function as managers when they make everyday practice decisions involving resources, co-workers, tasks, policies, and their personal lives. They do this in the settings of individual patient care, practice organizations, and in the broader context of the health care system. Physicians must use resources to effectively strike a professional/personal life balance. In addition, they use information technology to optimize patient care, life-long learning, and other activities. Thus, physicians require the abilities to prioritize and effectively execute tasks through teamwork with colleagues, and make systematic decisions when allocating health care resources.

Health Advocate: Physicians recognize the importance of advocacy activities in responding to the challenges represented by those social, environmental, and biological factors that determine the health of patients and society. They recognize advocacy as an essential and fundamental component of health promotion that occurs at the level of the individual patient, the practice population, and the broader community. Health advocacy is appropriately expressed both by the individual and collective responses of physicians in influencing public health and policy.
back to top
Scholar: Physicians engage in a lifelong pursuit of mastery of their profession. They recognize the need to continually learn by developing, implementing, and monitoring personal continuing education strategies. Through their scholarly activities, they contribute to the appraisal, collection, and understanding of health care knowledge, and contribute to the development of new knowledge. They also facilitate the education of their students, patients and others.

Professional: Physicians, as professionals, have a unique societal role with a distinct body of knowledge, skills, and attitudes dedicated to improving the health and wellbeing of others. Physicians are committed to the highest standards of excellence in clinical care and ethical conduct, and to the pursuit of mastery of their discipline. They deliver the highest quality care with integrity, honesty, and compassion and practice medicine ethically, consistent with the obligations of a physician.
