 t\n\nSurveillance bias occurs when variations in the frequency of a health
  event result from differences in the modality or intensity of detection\,
  rather than actual changes in its underlying risk. These differences ofte
 n arise from varying screening and diagnostic strategies over time or acro
 ss populations\, care settings\, and types of patients. As a result\, popu
 lation health monitoring indicators\, such as disease incidence or quality
 -of-care metrics\, are biased\, leading to misinterpretations and potentia
 lly wrong public health decisions. This bias can also lead to incorrect es
 timates of the association between an exposure and a health event due to d
 ifferences in detection modalities of the event across exposure subgroups.
  In this talk\, I will discuss this bias\, its impact on cancer epidemiolo
 gy\, and how to prevent it.\n\nLearning Objectives\n\nAt the end of this t
 alk\, attendees will:\n\n\n	Know what is surveillance bias and several cond
 itions exposed to this bias\;\n	Understand the impact of surveillance bias 
 on cancer epidemiology\;\n	Know the causes of this bias and how to prevent 
 it.\n\n\nSpeaker Bio\n\nArnaud Chiolero\, is an epidemiologist and public 
 health physician (board certified). He is a full professor of population h
 ealth at the University of Fribourg and an adjunct professor at the School
  of Global and Population Health at 51³Ô¹ÏÍø. He is the director 
 of the Population Health Laboratory (#PopHealthLab) at the University of F
 ribourg and academic co-director of the Swiss School of Public Health (SSP
 H+). Initially trained as a medical doctor (MD) at the University of Lausa
 nne in Switzerland\, he trained in epidemiology at Erasmus University Rott
 erdam in the Netherlands (MSc) and at 51³Ô¹ÏÍø in Montreal in Can
 ada (PhD). He leads epidemiological research focusing on the life course e
 pidemiology of chronic diseases and public health surveillance.\n
