In November 1997, by the initiative of allergists and ANAICE commissions of harmonization and allergy practice were created to improve the quality of care. The summary of the results is reported of one of the commissions, that on urticaria. The common attitudes and disagreements between the allergists from different faculties and who worked in different towns are presented. The work has also shown the importance of interactions between urticaria and mind in chronic urticaria in adults and has analysed invalidated indications. The work has obtained the support of the principal representative structures of liberal allergy: the SNAF, ANAFORCAL and ANAICE. It needs to be followed by scientific and rigorous methodology, like the audits of ambulatory medical practice. The harmonization commissions have done preliminary work which is indispensable for introduction of audits in the different sectors of activity in allergy.
