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 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.
Objective To explore the clinical effect of failure mode and effect analysis (FMEA) combined with PDCA cycle management model in the prevention and control of multidrug-resistant organisms (MDROs) in intensive care unit (ICU), and provide evidences for drawing up improvement measures in healthcare-associated MDRO infections in ICU. Methods In January 2020, a risk assessment team was established in the Department of Critical Care Medicine, the First People’s Hospital of Longquanyi District of Chengdu, to analyze the possible risk points of MDRO infections in ICU from then on. FMEA was used to assess risks, and the failure modes with high risk priority numbers were selected to evaluate the high-risk points of MDRO infections. The causes of the high-risk points were analyzed, and improvement measures were formulated to control the risks through PDCA cycle management model. The incidence of healthcare-associated MDRO infections in ICU, improvement of high-risk events, and satisfaction of doctors and nurses after the implementation of intervention measures (from January 2020 to June 2021) were retrospectively collected and compared with those before the implementation of intervention measures (from January 2018 to December 2019). Results Six high-risk factors were screened out, namely single measures of isolation, unqualified cleaning and disinfection of bed units, irrational use of antimicrobial agents, weak consciousness of isolation among newcomers of ICU, weak awareness of pathogen inspection, and untimely disinfection. The incidence of healthcare-associated MDRO infections was 2.71% (49/1800) before intervention and 1.71% (31/1808) after intervention, and the difference between the two periods was statistically significant (χ2=4.224, P=0.040). The pathogen submission rate was 56.67% (1020/1800) before intervention and 61.23% (1107/1808) after intervention, and the difference between the two periods was statistically significant (χ2=7.755, P=0.005). The satisfaction rate of doctors and nurses was 75.0% (30/40) before intervention and 95.0% (38/40) after intervention, and the difference between the two periods was statistically significant (χ2=6.275, P=0.012). Conclusions FMEA can effectively find out the weak points in the prevention and treatment of MDRO infections in ICU, while PDCA model can effectively formulate improvement measures for the weak points and control the risks. The combined application of the two modes provides a scientific and effective guarantee for the rational prevention and treatment of MDRO infections in ICU patients.
Objective To evaluate the effect of active screening and intervention of multidrug-resistant organisms (MDROs) on control nosocomial infection in the general intensive care unit (ICU). Methods A non-concurrent control trial was conducted in patients hospitalized in the ICU for more than 24 hours in the Second Affiliated Hospital of Fujian Medical University. Patients underwent active screening of MDROs for nasal vestibular swab, throat swab and rectal swab combined with further intensive intervention for patients with positive screening result during Sept. 2014 to Aug. 2015 were included as an intervention group, patients only underwent active screening during Sept. 2013 to Aug. 2014 were included as a screening group, and patients without undergoing active screening during Sept. 2012 to Aug. 2013 were as a control group. SPSS 19.0 software was used to compare the hospital infection rate and the infection rate of MDROs among the three groups. Results A total of 1 773 patients were included, of which 655 patients were in the intervention group, 515 patients were in the screening group, and 603 patients were in the control group. The difference of hospital infection rates among the three groups was statistically significant (χ2=21.087, P < 0.001), and further pairwise comparison results showed that the intervention group was lower than the screening group (χ2=5.891, P=0.015), and the screening group was lower than the control group (χ2=4.259, P=0.039). The adjustment daily infection rate of the intervention group, screening group and control group were 6.69‰, 10.88‰, and 15.39‰, respectively. The difference of MDROs hospital infection rates among the three groups was statistically significant (χ2=21.039, P < 0.001), and further pairwise comparison results showed that the intervention group was lower than the screening group (χ2=5.936, P=0.015), and the screening group was lower than the control group (χ2=5.798, P=0.016). The MDROs thousand daily infection rate of the intervention group was lower than that of the screening group (3.90‰ vs. 7.30‰, χ2=5.999, P=0.014). Conclusion The active screening plus intensive intervention of MDROs can effectively reduce the incidence rates of nosocomial infections and MDROs infections in ICU.
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.
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.
ObjectiveTo optimize procedures of going out for examination for patients with multidrug-resistant organism, strengthen prevention and control management of nosocomial infection, and prevent nosocomial infection.MethodsPatients with multidrug-resistant organism who went out for examination were selected from April to November 2018. April to July 2018 (before implementation) was process construction stage, and August to November 2018 (after implementation) was process optimization implementation stage. In April 2018, process and management system of going out for multidrug-resistant organism patients were formulated, training of transporters was strengthened, and measures such as checklist identification, accompany patients for examination, patient handover, isolation and protection, and disinfection of materials were implemented, to realize the infection prevention and control management in the whole process of going out for multidrug-resistant organism patients. We compared relevant indicators before and after implementation.ResultsA total of 262 cases times of patients with multidrug-resistant organism were included, including 134 cases times before implementation and 128 cases times after implementation. Compared with before implementation, the hand hygiene, wearing gloves, disinfection of inspection instruments and articles, patient transfer, isolation measures in waiting process (special elevator, isolation after waiting for inspection, arrange inspection time reasonably), education and training after implementation improved(P<0.05). Before and after implementation, the Methicillin resistant staphylococcus aureus detection rate difference was statistically significant (P<0.05).ConclusionsThe optimization of procedures of examination for patients with multidrug-resistant organism can increase implementation rate of indirect indicators such as hand hygiene, disinfection of inspection instruments and articles, isolation and protection, education and training in the prevention and control of multidrug-resistant organism in nosocomial infection. And it is important for the prevention and control of multi-disciplinary collaboration of multidrug-resistant organism.
Objective To explore the source and distribution of patients with multidrug resistant organisms (MDROs) acquired (infections/colonizations) outside the hospital and to provide a reference for guiding proactive interventions for nosocomial transmission of MDROs. Methods Bacterial culture results and clinical data of patients newly admitted to Beijing Anzhen Nanchong Hospital of Capital Medical University & Nanchong Central Hospita1 were retrospectively investigated between January 1st 2022 and December 31st 2023. The types of MDROs infections/colonizations, patient sources, and triple distributions of patients with nosocomial acquisition of MDROs were analyzed. Results A total of 293 patients with 308 infections/colonizations were investigated in the extranocomial infection of MDROs, 198110 newly admitted patients during the same period, and the total case rate of extranocomial infection of MDROs was 0.155% (308/198110). Among them, the case rate of extranocomial infection of methicillin-resistant Staphylococcus aureus (0.062%) and carbapenem resistant Acinetobacter baumannii (0.044%) were higher than those of other types of bacteria. The case rate of extranocomial infection of MDROs was statistically significant in terms of the distribution of the route of admission, gender of the patient, age of the patient, department of admission, and time of admission (P<0.001); The distribution of patients with extranocomial infection of various types of MDROs was correlated with admission route, patient age, and admission department (P<0.001), and the associations with patient gender and admission time were not statistically significant (P>0.05). Conclusions The total case rate of extranocomial infection of MDROs in the institution was at a relatively low level, and conducting large-scale active screening has certain limitations. Active screening factors should be considered in a comprehensive manner to capture differences in epidemiological characteristics of patients with extranocomial infection of MDROs, and targeted prevention and intervention should be carried out to achieve a reduction in infections from MDROs in hospitals.
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.
