Cost-benefit evaluation of homeopathic versus conventional therapy in respiratory diseases.

Methods: A retrospective observational study was conducted on 105 out of 233 patients suffering from chronic respiratory disease attending the Homeopathic Clinic of the Campo di Marte Hospital in Lucca (Tuscany, Italy) between October 1998 and May 2003. We assessed the cost of conventional medicinal products using Anatomic Therapeutic Chemical (ATC) classification, specific for the pathology in question, and the general costs in the year preceding the first appointment at the Homeopathic Clinic vs. the first and second year subsequent to homeopathic treatment.
