ObjectiveTo evaluate the effect of bundle strategies on the prevention and control of multidrug-resistant organisms (MDROs) in intensive care unit (ICU), in order to effectively prevent and control the severe situation of multiple drug-resistant bacteria in ICU.MethodsWe selected patients who admitted into the ICU from January 2016 to December 2017 as study subjects, and monitored 6 types of MDROs. Basic information was surveyed and collected from January to December 2016 (before intervention), while bundle strategies on MDROs were implemented from January to December 2017 (after intervention), including issusing isolation orders, hanging isolation marks, wearing isolation clothes, using medical articles exclusively, cleaning and disinfecting environment, implementing hand hygiene, etc. Then we compared the MDRO detection rate, nosocomial infection rate, MDRO nosocomial infection rate, and compliance rates of interventions between the two periods.ResultsThe MDRO detection rate before intervention was 77.10%, and that after intervention was 49.12%, the difference between the two periods was statistically significant (χ2=69.834, P<0.001). The nosocomial infection rate of ICU decreased from 23.51% before intervention to 15.23% after intervention, the MDRO nosocomial infection rate decreased from 13.70% before intervention to 5.84% after intervention, and the differences between the two periods were statistically significant (χ2=8.594, P=0.003; χ2=13.722, P<0.001). The compliance rates of doctor’s isolation orders, hanging isolation marks, wearing isolation clothes, using medical articles exclusively, cleaning and disinfecting environment, and hand hygiene, as well as the correct rate of hand hygiene after intervention (92.12%, 93.55%, 81.77%, 84.24%, 82.90%, 77.39%, and 96.37%) were significantly higher than those before intervention (31.94%, 52.00%, 23.43%, 48.18%, 67.16%, 59.46%, and 88.64%), and the differences were all statistically significant (P<0.001).ConclusionThe implementation of the above bundle strategies on the prevention and control of MDROs can decrease the MDRO detection rate and MDRO nosocomial infection rate.
Medical institutions of China still face two challenges in hospital infections currently: one challenge is from infection, including infectious diseases, multidrug-resistant bacteria healthcare-associated infection (HAI), and classic HAI; the another challenge comes from the management of HAI in medical institutions, such as lack of full-time staff and insufficient capacity, inadequate infection control organizations, insufficient awareness of infection control among medical staff, and unbalanced development. To cope with these severe challenges, we must do the following three aspects: establishing the discipline of HAI, and improving people’s infection control ability through human-orienting; improving the management organization and system of HAI; improving the awareness of infection control among all medical staff, carrying out scientific and orderly infection prevention and control work in accordance with the law, and adhering to evidence-based infection control.
ObjectiveTo explore the effects of burn ward cleaning methods on multi-drug resistant bacteria infection, in order to improve and optimize the cleaning process and method. MethodsFrom November 2012 to October 2013, the cleaning and disinfection methods in our burn wards were regarded as the traditional cleaning methods, and from November 2013 to October 2014, the cleaning and disinfection methods were called the improved cleaning methods (new system cleaning methods). By retrospective analysis, we compared the infection rates of multi-drug resistant bacteria before and after the implementation of the new system cleaning methods. ResultsNew system methods were used in the ward environment cleaning and disinfection. The infection rate of multi-drug resistant bacteria before and after the implementation of the new system cleaning methods were 12.414‰ and 5.922‰ respectively. The methicillin resistant Staphylococcus aureus infection rate was 7.286‰ and 3.718‰, and the carbon-resistant Pseudomonas aeruginosa infection rate was 2.699‰ and 0.689‰. Both differences were significant (P < 0.05). The carbon-resistant Acinetobacter baumanii infection rate was 2.429‰ and 1.515‰ before and after the implementation of the new methods with no significant difference (P > 0.05). ConclusionAdopting new system to carry out cleaning can effectively reduce the infection rate of multi-drug resistant bacteria in the burn ward, and it is worthy of clinical popularization and application.
ObjectiveTo explore the practical effects of multi-disciplinary team (MDT) management model in the management of multidrug-resistant organisms (MDROs).MethodsIn 2015, the multi-drug resistant MDT was established, and MDT meetings were held regularly to focus on the problems in the management of MDROs and related measures to prevent and control nosocomial infections of MDROs.ResultsThe detection rate of MDROs from 2014 to 2017 was 9.20% (304/3 303), 7.11% (334/4 699), 8.01% (406/5 072), and 7.81% (354/4 533), respectively. The difference was statistically significant (χ2=11.803, P=0.008), in which the detection rates of carbapenem-resistant Acinetobacter baumannii (CRABA), carbapenem-resistant Pseudomonas aeruginosa, and carbapenem-resistant Enterobacteriaceae (CRE) changed significantly (χ2=39.022, 17.052, 12.211; P<0.05). From 2014 to 2017, the proportion of multi-drug resistant infections decreased year by year, from 84.54% to 52.82%, and the proportion of multi-drug resistant hospital infections also declined, from 46.05% to 23.16%; the nosocomial infection case-time rate decreased from 0.24% to 0.13% year-on-year; the proportion of multi-drug resistant hospital infections in total hospital infections was 9.07%, 11.17%, 10.47%, and 6.16%, respectively; in the distribution of multi-drug resistant nosocomial infection bacteria, the proportion of methicillin-resistant Staphylococcus aureus, CRABA, CRE hospital infections accounted for the number of MDROs detected decreased year by year. The use rate of antibiotics decreased from 46.58% in 2014 to 42.93% in 2017, and the rate of pathogens increased from 64.83% in 2014 to 84.59% in 2017.ConclusionThe MDT management mode is effective for the management and control of MDROs, which can reduce the detection rate, infection rate, hospital infection rate, and antibacterial drug use rate, increase the pathogen detection rate, and make the prevention and control of MDROs more scientific and standardized.
Diabetic foot infection (DFI) is one of the main causes of hospitalized patients with diabetic foot. DFI should be diagnosed according to the clinical manifestations, and the severity of infection should be graded in time. Diabetic foot wounds are mostly chronic wounds, and there are many kinds of bacterial infections. The bacteria and antibiotics resistance will change with the progress of the disease. Bacterial biofilm is also one of the important causes of antibiotic resistance. Reasonable and timely surgical treatment combined with effective antibiotic treatment is an effective measure to deal with the challenge of DFI. On this basis, multidisciplinary cooperation will achieve the best clinical outcome.
Objective To evaluate the effect of ECRS management model on the quality of prevention and control of hospital infection with multidrug-resistant organisms (MDROs). Methods The data related to the prevention and control of MDROs in the First Hospital of Nanchang in 2020 and 2021 were retrospectively collected. The hospital implemented routine MDRO infection prevention and control management in accordance with the Expert Consensus on the Prevention and Control of Multi-drug Resistant Bacteria Nosocomial Infection in 2020. On this basis, the hospital applied the four principles of the ECRS method to cancel, combine, rearrange and simplify the MDRO infection prevention and control management. The detection rate of MDROs on object surfaces, the incidence rate of hospital infection of MDROs, the compliance rate of hand hygiene, the implementation rate of contact isolation prevention and control measures, and the pass rate of MDRO infection prevention and control education assessment were analyzed and compared between the two years. Results The detection rate of MDROs on the surfaces in 2021 was lower than that in 2020 (9.39% vs. 31.63%). The hospital-acquired MDRO infection rate in 2021 was lower than that in 2020 (1.18% vs. 1.46%). The hand hygiene compliance rates of medical staff, workers and caregivers in 2021 were higher than those in 2020 (90.99% vs. 78.63%, 73.51% vs. 45.96%, 70.96% vs. 33.71%). The implementation rate of contact isolation prevention and control measures in 2021 was higher than that in 2020 (93.31% vs. 70.79%). The qualified rates of MDRO infection prevention and control education in medical personnel, workers and caregivers in 2021 were higher than those in 2020 (96.57% vs. 81.31%, 76.47% vs. 47.95%, 73.17% vs. 34.19%). All the differences above were statistically significant (P<0.05). Conclusion ECRS management mode can improve the execution and prevention level of MDRO hospital infection prevention and control, and reduce the incidence of MDRO hospital infection.

Objective To analyze the distribution of pathogens, drug susceptibility and multi-drug resistant bacteria (MDRB) in elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with pneumonia. Methods The clinical data of patients whose discharge diagnosis included AECOPD with pneumonia or pulmonary infection from January 2012 to December 2015 were retrospectively analyzed. Strain identification and drug sensitivity analysis were performed in the pathogenic bacterias isolated from sputum culture. Results A total of 1 978 patients were enrolled in this study, and pathogenic bacterias were isolated from the sputum of 708 patients, including 485 cases of community-acquired pneumonia (CAP) and 223 cases of hospital-acquired pneumonia (HAP); and 786 strains of pathogens were isolated (501 strains from CAP cases, 285 strains from HAP cases), including 448 strains of Gram-negative (G–) bacilli (57.0%), 117 strains of Gram-positive (G+) cocci (14.9%), and 221 strains of fungi (28.1%). Susceptibility testing results showed that G– bacilli were highly resistant to penicillins, third generation cephalosporins, ciprofloxacin, gentamicin, etc., and G+ cocci were highly resistant to penicillin, clindamycin and erythromycin. There were 238 strains of MDRB, mainly including 69 strains of Acinetobacter baumanii [multiple drug resistance rate (MDRR)=67.6%], 27 strains of Escherichia coli (MDRR=52.9%), 25 strains of Klebsiella pneumoniae (MDRR=34.2%), 33 strains of Pseudomonas aeruginosa (MDRR=33.0%) and 24 strains of Stenotrophomonas maltophilia (MDRR=100.0%). MDRR of Enterococcus genus and methicillin-resistant Staphylococcus aureus was 50.0% and 48.0%, respectively. Conclusions The pathogenic bacterias in elderly AECOPD patients complicated with pneumonia are mainly G– bacterias, and the proportion of fungal infection tends to increase. Bacterial drug resistance is serious and the MDRB tends to increase, especially in patients with HAP. Physicians should early find out the characteristics of local pathogenic bacteria and drug sensitivity, rationally select antibiotics, reduce the occurrence of drug-resistant strains and superinfection when treating the elderly patients with AECOPD complicated with pneumonia.
ObjectiveTo understand the distribution characteristics and nosocomial infection of carbapenem-resistant Enterobacteriaceae (CRE) in a general hospital of traditional Chinese medicine, so as to provide the evidence for control and management of multidrug-resistant bacteria.MethodsData of CRE in the first Affiliated Hospital of Anhui University of Traditional Chinese Medicine were analyzed retrospectively from 2014 to 2018.ResultsThe total detection rate of CRE was 10.76%, 5.58%, 15.42%, 12.94% and 16.18% from 2014 to 2018, respectively. The detection rate of CRE showed a gradual upward trend (χ2=29.940, P<0.001). The highest number of CRE isolated from clinical specimens was sputum (355 strains, 63.39%), and the next were urine (98 strains, 17.50%) and secretions (38 strains, 6.79%). CRE isolated from different clinical departments were mainly in Neurosurgery Department (172 stains, 30.71%), Intensive Care Unit (Internal Medicine) (145 strains, 25.89%), Intensive Care Unit (Surgery)(106 strains,18.93%), and other internal medical departments (83 strains, 14.82%). A total of 179 patients developed CRE nosocomial infection in the past 5 years, who were mainly male, and with advanced age, long hospital stay, basic diseases, abnormal immune function and invasive operation. The incidence of hospital infection with CRE from 2014 to 2018 were 0.31‰, 0.38‰, 0.89‰, 0.80‰ and 1.14‰, respectively, which also showed a gradual upward trend (χ2=25.111, P<0.001).ConclusionWith the increasing number of clinically isolated CRE strains and the increasing incidence of nosocomial infection of CRE, effective intervention measures should be taken to prevent and control CRE.
ObjectiveTo analyze the risk factors of multidrug-resistant organism (MDRO) nosocomial infection, and to provide the scientific basis for the prevention and control of MDRO nosocomial infection.MethodsPatients with MDRO in Chengdu Shangjin Nanfu Hospital from 2014 to 2015 were retrospectively collected. The patients were divided into the MDRO nosocomial infection group and the MDRO non-nosocomial infection group. The MDRO infection/colonization, bacterial strain type, specimens type and distribution characteristics of clinical departments were analyzed. Single factor and multiple factor logistic regression analysis were used to analyze the risk factors of MDRO nosocomial infection.ResultsA total of 357 patients of MDRO infection/colonization were monitored, of which 147 times (144 patients) were with nosocomial infections and 213 times (213 patients) were without nosocomial infections. MDRO nosocomial infection incidence rate/cases incidence rate were 0.18%. A total of 371 MDRO bacterial strains were detected, of which 147 (39.62%) were with nosocomial infection and 224 (60.38%) were without nosocomial infections. The MDRO non-nosocomial infections included 175 strains (47.17%) in community infection and 49 strains (13.12%) in colonization. Carbapenem-resistant Acinetobacter baumannii (52.83%) was the main MDRO strains. Sputum (57.14%) and secretion (35.04%) were main specimens. The top three departments of MDRO nosocomial infection strains were orthopedics (32.65%), ICU (27.89%), neurosurgery (13.61%). ICU [odds ratio (OR)=3.596, 95% confidence interval (CI) (1.124, 11.501), P=0.031], surgical history [OR=2.858, 95%CI (1.061, 7.701), P=0.038], indwelling urinary catheter [OR=3.250, 95%CI (1.025, 10.306), P=0.045], and using three or more antibiotics [OR=4.228, 95%CI (1.488, 12.011), P=0.007] were the independent risk factors of MDRO nosocomial infection.ConclusionEffective infection prevention and control measures should be adopted for the risk factors of MDRO nosocomial infection to reduce the incidence rate of MDRO nosocomial infection.
