CIHI developed the National Prescription Drug Utilization Information System (NPDUIS) in consultation with the Patented Medicine Prices Review Board External link, opens in new window (PMPRB).

NPDUIS houses pan-Canadian prescription drug claims-level data, focusing primarily on publicly financed drug benefit programs. The database includes the following:

  • Claims data — Cost and utilization information on prescribed drugs. This information is used to measure and analyze prescription drug use in Canada.
  • Formulary data — Information on which drugs are included in public drug programs in Canada and how they are covered.
  • Drug product information — Used to identify drug products in a standardized format.
  • Plan information — An outline of the administrative policies of public drug plans or programs in Canada. This data may help explain differences in drug utilization patterns across the country.
