PASTOR GARCIA, Enrique; EIROS BOUZA, José María  and  MAYO ISCAR, Agustín. The Influence of Population Structure on Systemic Antibiotic Consumption Valladolid, Spain. Rev. Esp. Salud Publica [online]. 2002, vol.76, n.4, pp.293-300. ISSN 2173-9110.

Background: The high degree to which systemic antibiotics are consumed in our country makes a study of those factors determining the spread thereof necessary. Different parameters are involved in the unequal spread of their consumption, including: a) the epidemiology of the infectious processes b) the population-dependent factors and c) factors depending upon the prescribing physicians. This study is aimed at analyzing those determining factors depending upon the population (type of population and age). Methods: A longitudinal retrospective study based on systemic antibiotic consumption data provided by the company International Marketing Services (IMS) for the January 1, 1996-December 31, 2000 period. The consumption indicator used was the number of daily doses defined per 1000 inhabitants/day (DID). Six geographical areas in the province of Valladolid were placed under study, three of which were urban and the other three mainly rural. Results: The overall consumption by area was as follows: Medina del Campo (25.9DID), the capital city of Valladolid (23.4DID), Laguna de Duero (22.6DID), Northern Area (22.4DID), Southern Area (21.4DID) and, lastly, the Central Area (20.2DID). The specific consumption by areas revealed a greater consumption of amoxicillin in the three urban areas, amoxicillin-clavulanic acid and the major macrolides in Medina del Campo, quinolone antibiotics in the Northern Area and tetracyclines and sulfonamides in the capital city of Valladolid. Conclusions: Major overall consumption-related differences were found to exist among areas, the maximums being found in the urban areas. These differences were more marked on when studying the geographic spread of the consumption of the main active ingredients.
