Abstract
BACKGROUND: According to previously studies, nosocomial infections (NIs) surveillance could effectively reduce infection rates. As NIs surveillance systems have been implemented in some hospitals for several years, their impact on NIs need to be explored. Therefore, the purpose of this review is to evaluate the tendency of NI rates during the surveillance period and the impact of surveillance on NI rates. METHODS: A systematic literature search of the PubMed database to identify papers that evaluated effect of surveillance on NIs, all kinds of NIs occurred during hospitalization or discharged were included. Exclude articles investigated the surveillance combined with other infection control measures. RESULTS: Twenty-five articles were included. NI rates had different levels of reduction during surveillance period, the reduction were not limited by state, department, surveillance system, and NI type. Continuous surveillance had a positive impact on NI, OR/RR were ranged from 0.43 to 0.95. CONCLUSION: Participation in NI surveillance is associated with reducing infection rates, though RCTs need to further prove the effective role of surveillance. Hospitals may consider to perform NIs surveillance systems according to its own conditions.
