Which data do we collect?

All medical data are separately stored from the registration data under a unique code number in our database. They are therefore not directly traceable to an individual.

Current overview of Hepatitis C data collection (in Dutch)

Demographic and geographic information: relevant demographic and geographic data such as date of birth, country of birth and nationality.

History: information about relevant (liver) disorders in the past, including hepatitis A or B infection, liver diseases, liver cancer, hemophilia and cardiovascular diseases.

Substance use: the use of substances that may influence the outcome of treatment or liver disease, such as smoking, alcohol and drug use.

Hepatitis C: relevant data about the infection with hepatitis C, such as start and stop date, symptoms, route of transmission, hepatitis C medication, dosage, start and stop date of the medication and the result of the treatment.

Laboratory test results

  • Hepatitis C diagnosis: the presence of hepatitis C virus particles (viral load) and antibodies against the hepatitis C virus.
  • HIV diagnostics: to rule out the presence of the HIV virus.
  • Virology and serology: the presence of other hepatitis viruses, antigens (proteins of micro-organisms) and antibodies.​​​​​​
  • Hematology: research into the function of blood and blood-forming tissues.​​​​​
  • Clinical chemistry: research into the presence of various substances such as proteins and hormones.​​​​​​​
  • Resistance to antiviral therapy: genetic code of pieces of the hepatitis C virus to investigate possible resistance to hepatitis C medication.

Liver diagnostics

  • Fibroscan, elastogram: examination date and results of a fibroscan and elastogram.​​​​​​​
  • Liver biopsy: collection date and results of a liver biopsy.​​​​​​​
  • Liver radiology: examination date and results of, for example, an ultrasound, CT or MRI scan of the liver.
