Efficiency of grid management mode of nosocomial infection prevention and control in reducing incidence of central venous catheter-associated bloodstream infection in ICU patients
OBJECTIVE To evaluate the effectiveness of the grid-based quality control management system in reduc-ing the incidence of central venous catheter-associated bloodstream infection(CABSI)in the intensive care unit(ICU)patients.METHODS The patients who were treated with central venous catheters for no less than 48 hours in comprehensive ICU of the First People's Hospital of Lianyungang from Jan 2021 to Dec 2023 were recruited as the research subjects and were divided into the pre-intervention period group(2021),the intervention period group(2022)and the maintenance period group(2023)according to the factor whether the grid-based quality control management system was carried out.The utilization rate of central venous catheter,incidence of CABSI and spe-cies of pathogens were observed and compared before and after the intervention.RESULTS The grid management team was established,the cluster prevention and control measures were optimized,the duties of the grid infection control staff were made clear,and the evidence-based training and grid-based quality control management system of assessment mechanism were established.After all of the above strategies were carried out,the utilization rate of central venous cathe-ter of the ICU patients was 67.77％in 2021,63.09％in 2022,51.22％in 2023.The incidence rate of CABSI was de-creased from 3.15‰ in 2021 to 0.75‰(P=0.001)in 2022 and 0.94‰ in 2023(P=0.002).Totally 29 strains of pathogens were isolated from the patients with CABSI,55.17％of which were gram-positive bacteria;there were 13 strains of multidrug-resistant organisms,and methicillin-resistant coagulase-negative Staphylococcus(MRCNS)was the most common.CONCLUSION The grid-based quality control strategies can remarkably reduce the risk of CABSI in the ICU patients and facilitate the prevention and control of nosocomial infection.
