  1. IMPACT OF REGULATORY MEASURES ON ANTIBIOTIC SALES IN CHILE. Bavestrello L, Cabello A. Gustavo Fricke Hospital.Viña del Mar.CHILE

  2. Introduction • Antibiotics are drugs used in the prevention and treatment of infections caused by pathogenus microorganisms. • Its use must be linked to a medical prescription since they can present adverse reactions and its use is related to an increase of bacterial resistance. • There is a relationship between antibiotic consumption in the community and the appearance and spreading of resistance.

  3. Introduction • Therefore, the indiscriminate use of antibiotics increases the appearance of bacterial resistence and forces the use of more expensive alternatives. • A previous study done by us in 1998, about the ten years tendency in antibiotics consumption, showed a large increase between 1988 and 1997.This study and many meetings with several organizations created the intervention possibility.

  4. Introduction • After that, the Chilean Ministry of Health decided an intervention to regulate the consumption of antibiotics since September 1999, as a strategy to encourage the rational use of antibiotics.

  5. OBJECTIVE • To study the impact of the 1999 regulatory measures on antibiotic sales implemented by the Chilean Ministry of Health in community pharmacies.This study was carried out in three ways: • in DDD/1000 inh-day as a consumption unit • in sale units • In money, expressed in USD during seven years, from 1996 to 2002.

  6. METHOD 1) Definition of the consumption unit used: DDD/1000 inhabitants-day a)Census population data of Chile. b)Annual sales data for antibiotics. I.M.S. 1996 to 2002. 2) Calculation of the Nº of DDD sold for each antibiotic: DDD/1000 inhabitants/day = sold grams x 1000 DDD spe.x Nºdays x Population

  7. Intervention: In order to obtain the intervention decision, we participated in many meetings with organizations related with public health like: • Chilean Infectious Disease Society • Chilean Microbiology Society • Chilean Pharmacology Society • Public Health Institute • Professional organizations of Physicians and Pharmacist • National Congress Health Committee • National Department of Consumers.

  8. The basis of action Plan to assure antibiotics rational use • The antibiotic use must respond to a diagnosis and medical prescription. • The dispense of the antibiotics must take place in the presence of a prescription. • The condition of sale written in the package of each antibiotic pharmaceutical product must be executed in all circunstance and at any moment.(Document 4C/4619, September 1999)

  9. Contents of the action plan: • To achieve the antibiotic sale restriction (sale only with prescription). • Population Information: leaflets and posters in community pharmacies. • Extensive coverage on radio, television and newspaper. • Educational campaign. • Test the compliance of the sale restriction.

  10. Results • There was an important reduction in consumption, expressed as DDD/1000 inh.-day, after the introduction of the regulatory measures for the most oral antibiotic groups. • After 1999, there was also an important fall in sale units and also in sales expressed in US dollars. • This tendency is mainteined during the last 3 years.

  15. CONCLUSIONS • The regulatory measures in 1999 had an important impact in the community antibiotic consumption in Chile. • The regulatory measures contributed to a considerable saving of money in the community due to a decrease in antibiotic use. • The success of the long term program depends on the compliance, maintenance, supervision and control of these measures by involved parts, including physicians, prescriptors, pharmacist and community in general.
