Repeated point prevalence survey on antimicrobial use in a university hospital: what have we learned?

Abstract Objectives To evaluate the quality of antimicrobial prescribing, at the Department of Internal Medicine University Hospital Centre Rijeka, by assessing the necessity for antimicrobial treatment and adherence to the local Guidelines for hospital antimicrobial drug use and to compare results with previously conducted point prevalence surveys (PPSs). Methods A PPS was conducted on 7th May 2019. Demographic and relevant clinical data of each patient receiving systemic antimicrobials were recorded anonymously in a patient-specific form. The appropriateness of antibiotic prescribing was assessed as adherence to the fourth edition of the Guidelines for hospital antimicrobial drug use. Key findings One hundred and seventy-one patients were hospitalized at the Department of Internal Medicine ; 37.4% (n = 64) of patients received 102 prescriptions for an antimicrobial drug [62.8% (n = 64) of prescriptions were for intravenous and 37.2% (n = 38) for oral administration]. Of these, 52 were treated for an identified existing infection, 5 were treated for an unknown indication and 7 received antibiotics as prophylaxis. The necessity for antimicrobial treatment was unclear in 19.3% (n = 11) of cases. The antimicrobials were prescribed according to the Guidelines in 65.4% (n = 34) of cases. Adherence to the Guidelines when treating lower respiratory tract infections, urinary tract infections and gastrointestinal tract infections was 47.8%, 55.6% and 92.9%, respectively. Conclusions Our study revealed antibiotic prescription frequency similar to EU/EEA average and high percentage of unjustified antimicrobial treatment introduction. The rate of adherence to the Guidelines was lower than those observed in western countries. The results lay a basis for tailoring antimicrobial stewardship programs/activities.
