ABSTRACT
Objective To evaluate the effect of targeted monitoring and multi-modular improvement strategy on the prevention and control of catheter-associated urinary tract infection(CAUTI).Methods Patients with indwe-lling urinary catheter in a tertiary first-class hospital from January 2018 to December 2022 were selected as the re-search subjects.Targeted monitoring results and distribution of pathogenic bacteria in 5 consecutive years were ana-lyzed,and a multi-modular improvement strategy based on the targeted monitoring results was implemented.The occurrence of CAUTI before and after implementation,status and effectiveness of training in prevention and control measures were compared respectively.Results Before and after the implementation of the multi-modular improve-ment strategy,health care workers'compliance rate of hand hygiene,awareness rate of prevention and control measures,and implementation rate of prevention and control measures all increased significantly(all P＜0.001).Targeted monitoring results showed that daily test rates of urine culture and routine urine from patients with in-dwelling catheters have been on the rise in 5 consecutive years(P＜0.05).A total of 397 cases of CAUTI occurred in the past 5 years.Incidences of CAUTI in general intensive care unit(ICU)and surgical ICU showed decreasing trends in 5 consecutive years(all P＜0.05).Incidence of CAUTI in general wards showed no statistically significant difference in 5 years(P=0.088).A total of 431 strains of pathogenic bacteria were detected,mainly Gram-negative bacteria.Daily incidence of multidrug-resistant organism infection in patients with indwelling catheters was 0.12‰.After the implementation of the multi-modular improvement strategy,incidence of CAUTI in all departments re-duced significantly(P＜0.05).Conclusion Targeted monitoring can help identify departments with high-risk of CAUTI,multi-modular improvement strategy can raise the quality of prevention and control of CAUTI in all occa-sions,reduce the incidence of CAUTI,and is worthy of clinical promotion and application.
ABSTRACT
Objective To explore the effect of multi-disciplinary team (MDT) combined with bundle management on prevention and control of multidrug-resistant organism (MDRO) infection in the intensive care unit(ICU).Methods Patients who were admitted to the ICU in a tertiary first-class hospital from January 2013 to December 2015 were studied,MDT combined with bundle management has been applied in the prevention and control of MDRO infection in ICU since January 2014,continuous quality improvement program was performed one year later,isolation of MDROs from specimens of ICU patients before implementation(in the year of 2013),after implementation(in the year of 2014),and after continuous quality improvement(in the year of 2015) was compared.Results The infection rates of MDROs in ICU patients before implementation,after implementation,and after continuous quality improvement were 26.55％ (154/580),17.13％ (117/683),and 12.01％ (77/641) respectively,showing a downward trend,with a significant difference (x2 =44.030,P＜0.001);the total isolation rates of MDROs in ICU patients were 64.44％(154/239),63.59％(117/184),and 43.26％ (77/178) respectively,showing a downward trend,with a significant difference (x2 =22.284,P＜0.001).The main MDROs in ICU were multidrug-resistant (MDR) and pandrug resistant(PDR) Acinetobacterbaumannii (44.54％).Conclusion MDT combined with bundle management can decrease MDRO infection rate and isolation rate in ICU.
