Participation in pooled analyses
 

  • The cohort is potentially interested in participating in pooled analyses of (European) occupational cohort studies (note pooled analyses also includes remote decentralized analyses that would not require any transfer of primary data as well as meta-analyses).
Main aim of cohort, please briefly describe the main objectives of the cohort
  Royal Decree on Occupational Medicine [6], Art.79.-§1 (translated in English): “In the medical file of the employee, all relevant information is collected so that the occupational physician is able to carry out the occupational health services."
Study design (please select as many as appropriate)
 

  • Intervention study
Source population (please select as many as appropriate)
 

  • General population: National
  • General population: Regional
Comparators (please select as many as appropriate)
 

  • Internal study population
Inclusion criteria
  Employees working for an employer who chose IDEWE as official External Service for Protection and Prevention at Work (ESPPW), for the corresponding follow-up period.
Exclusion criteria
  Employees leave the cohort (temporarily or not) when their employer leaves IDEWE, or when they change job to an employer who is not tied to IDEWE as ESPPW, or when they leave the active working population in Belgium.

Comments
  Open, dynamic cohort, with (partly temporary) drop-outs and no later follow-up.
Data is collected during different types of medical examinations (compliant with legislation and depending on employer's decision).
A medical examination is not a questionnaire, and visit time is very limited, so missing values are normal.
Different database management systems and data collection were used in the past, so the reported enrollment period 1993-2020 is not 'fluid'.

  • Active (contact with participants)
  • Other (specify)
Active (contact with participants) (specify)
 

  • At the time of medical examination, immediate feedback is already given by the physician (e.g. heart score).
Specify: Other
 

  • Aggregated reports for the employer and their committees for safety and health at work
First follow-up period (provide year)
  can vary between 1993 and 2020, on a per-employee basis
Last follow-up period (provide year)
  can vary between 1993 and 2020, on a per-employee basis
Number of follow-ups after baseline (provide number)
  can vary, on a per-employee basis
Comments
