 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 91ºÚÁÏÍø. 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 91ºÚÁÏÍø 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
