RESUMEN
Healthcare-associated infections caused by multidrug-resistant organisms are associated with prolonged medical care, worse outcome and costly therapies. In Hungary, hospital-acquired infections (HAIs) due to epidemiologically important multidrug-resistant organisms are notifiable by law since 2004. Overall, 6,845 case-patients (59.8% men; median age: 65 years) were notified in Hungary from 2005 to 2010. One third of case-patients died in hospital. The overall incidence of infections increased from 5.4 in 2005 to 14.7 per 100,000 patient-days in 2010. Meticillin-resistant Staphylococcus aureus (MRSA) was the most frequently reported pathogen (52.2%), but while its incidence seemed to stabilise after 2007, notifications of multidrug-resistant Gram-negative organisms have significantly increased from 2005 to 2010. Surgical wound and bloodstream were the most frequently reported sites of infection. Although MRSA incidence has seemingly reached a plateau in recent years, actions aiming at reducing the burden of HAIs with special focus on Gram-negative multidrug-resistant organisms are needed in Hungary. Continuing promotion of antimicrobial stewardship, infection control methodologies, reinforced HAI surveillance among healthcare and infection control practitioners, and engagement of stakeholders, hospital managers and public health authorities to facilitate the implementation of existing guidelines and protocols are essential.

In 2004, a secure web-based national nosocomial infection surveillance system was established in Hungary. The system, named NNSR (Nemzeti Nosocomiális Surveillance Rendszer), is based on the US National Nosocomial Infection Surveillance System (NNIS). Surgical procedures, definitions, surveillance methodology and patient risk indices are those established by NNIS. In this paper, we present the results of the first two years of the surgical patient component of our system. During this period, 41 hospitals participated and selected 11 surgical procedures for surveillance. Altogether 15812 procedures were surveyed and 360 resulting surgical site infections (SSI) were recorded. The overall SSI rate was 2.27%. The most commonly selected procedures and corresponding SSI rates were caesarean section (1.31%), herniorrhaphy (2.09%), cholecystectomy (1.52%) and hip replacement (2.91%). Standardised infection ratios (SIR) were calculated for chosen surgical procedures in order to compare against NNIS published rates. SSI rates for colonic surgery, caesarean section and mastectomy were lower than expected according to the NNIS data but higher for cholecystectomy, herniorrhaphy and hip prosthesis infection rates. We intend to recruit more participating hospitals, leading to a robust national database that can be used to target infection control interventions for patients in Hungary.
