Abstract


Background: Routine follow-up is a cornerstone of oncology practice but evidence is lacking to support most aspects.   Our Objective was to investigate the relationship between frequency of routine follow-up and survival.

Methods: A population-based study using electronic health-care data based on 5310 patients from Ontario diagnosed with squamous cell head and neck cancer between 2007 and 2012.  Treatments included surgery (24.6%), radiotherapy +/- chemotherapy (52.4%) and combined surgery and radiotherapy (23%).  We determined the follow-up oncologist for each patient, calculated the average follow-up visits over 2.5 years for all the patients of each oncologist and compared by treatment the overall survival of the patients for the high, medium and low follow-up oncologist groups using Kaplan Meier and multiple variable regression analysis. 

Results:  Many oncologists saw patients 40 to 80% more often than others. There was no relationship between appointment frequency and survival for patients for any treatment group.

Conclusion:  The practice of routine follow-up varies and is costly to both a health care system and to patients.  Without evidence on the effectiveness of our current policies further research is required to investigate new or optimal practices.
