[Prescribing appropriateness, use and consumption of antibiotics in Italy. An extract from the National Report 2018.].

INTRODUCTION

Antimicrobial resistance is a major global public health concern. In Italy, in 2017, the National Plan to Fight Antimicrobial Resistance (PNCAR 2017-2020) was approved, in line with the Global One Health Action Plan. Despite the decreasing trend, the consumption of antibiotics in Italy continues to be higher than the European average, with a great variability between regions. In the European investigation on the distribution of resistant bacteria in Europe, Italy holds together with Greece the record for the spread of resistant germs.

OBJECTIVE

The present study, dedicated to antibiotics for human use, allows to monitor the trend of consumption and expenditure in Italy and at the same time to identify areas of potential inappropriateness of use.

METHODS

The analyses presented concern the use of antibiotics in the community setting, with a focus on consumption in the paediatric population and on the prescription of fluoroquinolones in specific population subgroups. In addition, the analysis on the use of antibiotics in hospital settings, the analysis on the private purchase of reimbursed antibiotics and the evaluation of indicators of appropriateness of antibiotic prescribing were also included. The analyses are based on the reading and integration of the data collected through different administrative healthcare databases: OsMed, Purchase by public health facilities, Direct distribution, Hospital consumption, Monitoring of pharmaceutical prescriptions, Private purchase by citizens, Hospital Discharge Records (Schede di Dimissione Ospedaliera, SDO), InfluNet surveillance.

RESULTS

The consumption of antibiotics in Italy in 2018 stood at 21.4 DDD/1000 ab. die and, despite the downward trend, is still above the European average. In terms of consumption within the territory (community setting), there is a considerable regional variety - ranging from 8.9 of the provincial government of Bolzano to 23.4 DDD/1000 ab. die of Campania (national average 16.1 DDD) - with higher values in the South and the Islands and lower in the North. The differences in drug use concern not only the number of prescriptions but also the type of antibiotics prescribed (type of molecules; broad spectrum vs. narrow spectrum). The association amoxicillin/clavulanic acid is the most widely used antibiotic both in the community and in hospitals. In the paediatric population (0-13 years) there is a peak prevalence of use of 50% in the first year of life of the child, with no differences between males and females. The consumption of antibiotics in hospitals is increasing in the three-year period 2016-2018 and presents a wide variability between different geographical areas.
