Monitoring of the territorial consumption of antibiotics in local health authority of Vercelli as a measure to contrast AMR.

In 2022 the Italian Ministry of Health published the National Antibiotic Resistance Plan (PNCAR) 2022 - 2025 which provides the strategic guidelines and operational indications for dealing with the emergency of antimicrobial resistance (AMR). ESAC recorded, in the year 2021, an average consumption of 16.4 DDD/1000 inhab. res. die, with a statistically significant decrease in the period 2012 -2021 for class J01, on total territorial and hospital consumption. Italy is one of the countries with the highest consumption of antibiotics, it ranks 9th with a total hospital and territorial consumption of 17.53 DDD/1000 inhab. res. die. The present study aims to monitor the territorial consumption of antibiotics in ASL VC through the analysis of synthetic indicators and ESAC indicators, comparing them with regional and national values. Through the IQVIA database, a retrospective descriptive study was conducted on the consumption of antibiotics (ATC J01), for the period 2020 - 2022, measuring the synthetic indicators of consumption (DDD1,000 inhab. res. die) and costs (value1,000 inhab. res. die). Subsequently, a second analysis was carried out by measuring the ESAC indicators for the year 2022, comparing them with the previous year or period. With regard to consumption, while a reduction (average -7%) was observed for contracted pharmaceuticals (CONV) in 2021 compared to 2020, followed by an increase in 2022 (average +31%); for private purchase (PRIV), consumption remained constant in 2021 and then increased in 2022 (average +40%). The same trend was observed for the costs of the J01 class. The ESAC indicators show a mild improvement for ASL VC (variable for regional and national level), except for the use of 3rd and 4th generation cephalosporins which recorded an increase in 2022. The reduction in the consumption of antibiotics in 2021, followed by an increase in 2022 can be partly explained by the pandemic period that has just ended which led to the return to the community with the resumption of infectious agents in circulation. It therefore becomes essential to pay particular attention to antibiotic stewardship activities, both in the hospital and on the territory. (community).
