Frequently Asked Questions


Claims data represent the prescription volume of only part of the market for your product or therapeutic area. Qalcul estimates the patient volume for the entire market, including both current and potential users. In other words, claims show the numerator whereas Qalcul shows the denominator.

In addition, given the interaction between public and private drug plans, claims will not necessarily provide a clear idea of where patients are covered. Qalcul provides that clarity by reporting patients in the correct segment.

Yes. Whereby there might not be any claims for a previously untreated disease, Qalcul can estimate patient coverage for that potential market.

For now, there is no option to save an unfinished questionnaire. It is required to complete all four steps and process responses. This should only take a few minutes.


The Qalcul model estimates at between 23 and 24 million the number of individuals insured through a private plan in Canada.

It is possible. A patients with dual public and private coverage will be reported in the column ''provincial plan'' or ''NIHB'' if the public plan reimburses the drug, and in the column ''private plan'' if only the private plan reimburses the drug. Hence, in a situation where public plans do not reimburse the drug, it is possible that the number of patients covered by private plans be higher vs. a situation where public plans would reimburse the drug (because of that dual coverage).

The Qalcul model applies realistic assumptions and gives precedence to provincial plans. Therefore, if a provincial plan in a given province reimburses the product, it is realistic to assume that all private plans in that same province will reimburse it as well. As a general rule, it is unlikely that a private plan would not reimburse a drug which is reimbursed by the provincial plan.

The strength of the Qalcul model is to combine several data sources to obtain an accurate and comprehensive picture of the entire market. It uses statistics published by provincial and federal governments on their drug plans beneficiaries, as well as public plan eligibility rules. It uses published statistics and surveys on private insurers to determine their respective volume of lives covered in each province. It uses family income statistics to establish deductible thresholds for universal or catastrophic plans in the various provinces. Finally, we apply our expertise to combine these sources in a coherent fashion to produce high quality estimates.
