National Panel of the Chronically ill and Disabled (NPCD)

The National Panel of the Chronically ill and Disabled (NPCD) is a nationwide Dutch panel, established to gather information on the consequences of chronic disease and disability from a patient perspective.

Onderzoek met het Nationaal Panel Chronisch zieken en Gehandicapten (NPCG)One of Nivel's national panels

Nivel's National Panel of the Chronically ill and Disabled (NPCD) is part of Nivel's research infrastructure, which consists of panels, national databases and monitors. With this research infrastructure, Nivel provides relevant information from different perspectives: that of patients, clients and citizens, that of healthcare providers and that of the organisation of healthcare.


By gathering information on the consequences of chronic disease and disability from a patient perspective, we aim to help policy makers in improving the care for chronically ill and disabled members of the society.

The NPCD consisted of more than 4,000 people with chronic illness or physical disability.

For the NPCD, participants are recruited from random samples of general practices that are drawn from the Dutch Database of General Practices. They are selected according to the following criteria:

  • diagnosis of a somatic chronic disease by a certified medical practitioner
  • aged 15 years or more
  • not permanently institutionalized, aware of the diagnosis, not terminally ill (their life expectancy is more than six month according to their general practitioner)
  • mentally capable of participating
  • sufficient mastery of the Dutch language

Members of NPCD are also recruited on the basis of a self-reported moderate or severe physical disability from several national population surveys conducted by the Statistics Netherlands (CBS).


Panel members fill in questionnaires at home twice a year.
