Consensus Method to Evaluate the Conformity of Prescription of a Chemotherapy

Cabazitaxel is a second line chemotherapy drug recently approved for the treatment of metastatic castration-resistant prostate cancer. To investigate whether the precautions for the use of cabazitaxel (contraindications, hepatic function, premedication for hypersensitivity, prophylactic treatments, dose and dose adjustment, as well as conditions of administration) are respected in routine practice, an observational cohort study will be implemented in 32 oncology centres of South-West region of France (CABOBS study). The primary objective of this cohort is to evaluate the conformity of cabazitaxel prescriptions with the Summary of Product haracteristics (SPC) in clinical practice (indications and monitoring methods) and according to the conditions of use. Panel of experts were convened to assess the conformity of prescription of cabazitaxel with a Delphi consensus method. The Delphi method is most suited to areas where a limited number of evidences are available to enable a recommendation or guidelines to be drawn. Moreover, all the evaluated items came from an official document provided by the EMA, the SPC of cabazitaxel. Thus, it is expected from the experts to select the most relevant items. In the frame of the CABOBS study, this method will allow to select items of the SPC list according to their importance, and to define the primary objective of conformity to cabazitaxel conditions of use.
