Strategies to control antibiotic resistance: results from a survey in Italian children's hospitals.

Abstract

Antimicrobial stewardship programs and comprehensive infection control programs represent the main strategies to limit the emergence and transmission of multi-drug resistant bacteria in hospital settings. The purpose of this study was to describe strategies implemented in Italian children's hospitals for controlling antibiotic resistance. Cross sectional multicenter study. Four tertiary care Italian children's hospitals were invited to participate in a survey aimed at collecting information on activities implemented as of December 2015 using a self-administered online questionnaire. The questionnaire was divided in three sections focalizing on: i) policies for prevention and control of hospital-acquired infection, ii) prevention and control of multi-drug resistant bacteria, and iii) antibiotic prescribing policies and Antimicrobial stewardship programs. Questionnaires were compiled between May and July 2016. All hospitals had multidisciplinary infection control committee, procedures on hand hygiene, isolation measures, disinfection/sterilization, waste disposal and prevention on infections associated to invasive procedures. All sites screened patients for multi-drug resistant bacteria colonization in selected units, and adopted contact precautions for colonized patients. Screening during hospitalization, or in case of infections in the same ward were not universally implemented. All hospitals had policies on surgical prophylaxis, while policies on medical prophylaxis and treatment of bacterial infections varied among sites. Two sites recommended to review the appropriateness of antibiotic prescribing after 48-72 hours and one recommended de-escalation therapy. This study highlighted several areas of improvement, such as actions for screening patients in case of occurrence of multi-drug resistant bacteria, antimicrobial stewardship programs and implementation of policies targeting antibiotic prescriptions for therapeutic purposes and medical prophylaxis.
