For some time, the Department of Surgery has been working on a process to assist with late career transitioning amongst surgeons on our faculty. Following a meeting of the Surgeon-in-Chiefs last fall, I appointed Robin Richards, Vice-Chair Clinical, and Ori Rotstein, Associate Chair, to write a draft document to encompass the principles that could be applied to late career surgeons.  After several iterations, and edits, I am pleased to provide you with the wording of the “Guidelines for Late Career Transition”  that has now been approved by the Executive Committee and the Senior Advisory Committee of the Department of Surgery.   Special thanks are given to Robin and to Ori for enabling us to finalize a document which, to my knowledge, is a first of its kind across Canada and perhaps North America on this topic.

In the absence of a defined retirement age, Department members need to develop plans for transition as they approach the end of their academic surgical careers.  The development of a plan for late career transition represents an opportunity for Department members to initiate a constructive process in co-operation with the Department, as represented by their Surgeon-in-Chief, the Hospital Division Head, and the University Division Chair.  The goal of the process is to develop an individual plan for each Department member that is agreeable to the academic surgeon, informs the relevant stakeholders and allows the late career surgeon, the Hospital, the Division and the Department to make plans for the future.  The following guidelines were developed to assist Department members in the development of individual plans for late career transition.

  1. All Department members should develop an awareness of and a plan for their late career transition.
  2. The development of a constructive plan for late career transition takes several years and discussion of individual plans should be initiated as part of the annual review process by the Surgeon-in-Chief at the Hospital.  
  3. University Departmental and Divisional policies and initiatives, such as the annual Assessment of Academic Performance, should be acknowledged and used to inform and guide the annual discussion regarding transition that occurs between the Surgeon-in-Chief and late career transition surgeons.
  4. Hospital resource utilization by individual surgeons is linked to on-call responsibilities and both should decrease in a planned and orderly fashion as late career transition occurs.
  5. Academic opportunities for surgeons can continue or even increase as reduced hospital resource utilization occurs.  The involvement of late career surgeons, whose careers are transitioning, in mentoring and resource sharing with new recruits initiating their academic surgical practice is encouraged.
  6. A marked diminution of surgical activity does not preclude ongoing meaningful participation in Departmental activities, including teaching, research and administration.
  7. The Surgeon-in-Chief, Hospital Division Head, and University Division Chair should ensure that the contributions of late career surgeons are recognized at an appropriate point in each Department member’s career.
  8. The provision of optimum patient care is of paramount importance to all stakeholders and plans for late career transition need to be developed with this in mind.

Continuing Appointment Reviews (CARs)
The following Continuing Appointment Reviews (CARs) took place in April under the leadership of Ori Rotstein, Associate Chair, Department of Surgery.  
Jason Lee is a Lecturer with the Division of Urology, Department of Surgery, University of Toronto and a faculty member at St. Michael’s Hospital.  He completed medical school in 2004 and then urology residency training at the University of Toronto. He passed his Royal College exams and then completed 2 years of fellowship training at the University of California Irvine in Minimally Invasive Urologic Surgery and Surgical Education.  Dr. Lee specializes in the endourologic management of complex stone disease, laparoscopic and robotic management of renal and prostate disease, as well as renal transplantation.  His surgical education research interests include the use of simulation for the instruction and assessment of laparoscopic and robotic skills, as well as curriculum design and program evaluation for the improvement of MIS skills acquisition and OR team crisis management. His work is supported by several research grants, including the Royal College of Physicians and Surgeons of Canada.  From left to right:  K. Pace, J. Lee, N. Fleshner
Anand Govindarajan is a surgical oncologist in the Division of General Surgery at Mount Sinai Hospital and Princess Margaret Hospital, and Assistant Professor at the University of Toronto.  He completed medical school and a residency in General Surgery at the University of Toronto.  During residency, he completed a Masters of Science through the Department of Health Policy, Management and Evaluation.  Following this, Dr. Govindarajan completed a clinical fellowship in Surgical Oncology at Memorial Sloan-Kettering Cancer Center in New York City.   Dr. Govindarajan’s clinical practice involves the care of patients with gastrointestinal and peritoneal-based malignancies. His primary research focus is to study and narrow the gaps between current practice and best evidence in the treatment of these diseases, through the use of health services research methods and knowledge translation techniques.
