Estimation of mean number of daily hand hygiene procedures per patient can represent an effective and easy understandable method to evaluate adherence experience in a tertiary care pediatric hospital of Northern Italy

INTRODUCTION. Hand decontamination with alcohol-based antiseptic agents is considered the best practise to reduce healthcare associated infections. We present a new method to monitor hand hygiene, introduced in a tertiary care pediatric hospital in Northern Italy, which estimates the mean number of daily hand decontamination procedures performed per patient. METHODS. The total amount of isopropyl alcohol and chlorhexidine solution supplied in a trimester to each hospital ward was put in relation with the number of hospitalization days, and expressed as litres/1000 hospitalization-days (World Health Organization standard method). Moreover, the ratio between the total volume of hand hygiene products supplied and the effective amount of hand disinfection product needed for a correct procedure was calculated. Then, this number was divided by 90 (days in a quarter) and then by the mean number of bed active in each day in a Unit, resulting in the mean estimated number of hand hygiene procedures per patient per day (new method). RESULTS. The two methods had similar performance for estimating the adherence to correct hand disinfection procedures. The new method identified wards and/or periods with high or low adherence to the procedure and indicated where to perform interventions and their effectiveness. The new method could result easy-to understand also for non-infection control experts. CONCLUSIONS. This method can help non-infection control experts to understand adherence to correct hand-hygiene procedures and improve quality standards.
