Objective To design a nucleic acid information early warning system and evaluate the effect of the application. Methods 60 nurses working in the clinical department of Zhongnan Hospital of Wuhan University from August to October 2021 were selected by convenient sampling method, and the included nurses were divided into experimental group and control group. The experimental group used the nucleic acid information early warning system, and the control group used the nucleic acid registration in a common way. Statistical duration of the nucleic acid information, nucleic acid leakage detection rate and nurses job satisfaction after application were compared between the two groups. Results After the application of nucleic acid information early warning system, compared with the control group, the statistical duration of the nucleic acid information in the experimental group was shortened [(2.0±0.4) vs. (3.8±0.7) min; t=25.827, P<0.001], nucleic acid leakage detection rate decreased [1.4% vs. 6.9%; P=0.019]. The job satisfaction of the experimental group was higher than that of the control group (P<0.001). Conclusions Applying the nucleic acid information early warning system could reduce statistical duration of the nucleic acid information, nucleic acid leakage detection rate and improve nurses job satisfaction and work experience. It will provide reference and basis for medical institutions to normalize the management of nucleic acid prevention and control in medical institutions.
Objective To analyze and discuss the research progress, hot spot, frontier and trend of the influence of high frequency hand hygiene on hand skin symptoms and hand microflora of health care workers by bibliometric analysis. Methods PubMed, Embase, Web of Science, Scopus, CNKI, Wanfang database, Chinese Biomedical Literature Service System and Cochrane Library were searched for related literatures on the effects of high-frequency hand hygiene on hand skin symptoms and hand microflora of health care workers from January 1st, 2014 to December 31th, 2024. NoteExpress 3.7.0.9296 and CiteSpace 6.1.R3 software were used to analyze the popular topics and generate a visual map to further refine research trends. Results A total of 1 607 articles were retrieved, and 126 were included after screening. The number of publications was relatively low before 2019, followed by a fluctuating upward trend from 2019 onward, reaching its peak in 2020. After 2020, the number of publications gradually declined and subsequently stabilized at a consistent level. Keyword co-occurrence analysis and keyword cluster analysis showed that the research focuses on the influence of high-frequency hand hygiene on hand skin symptoms and hand microflora of health care workers were hand eczema, hand sanitizer and protective equipment. The keyword burst analysis showed that the keyword with the strongest outbreak intensity was 2-propanol while the keyword with the longest outbreak duration was staphylococcus aureus. Conclusions In recent years, the influence of high frequency hand hygiene on hand skin symptoms and hand microflora of health care workers has gradually attracted attention. Current research highlights indicate that studies on different types of hand skin symptoms caused by high-frequency hand hygiene, the variation patterns of hand microbiota, the rationality of hand hygiene frequency in various medical work scenarios, and the development and application of protective hand sanitizer formulations or devices will become future research trends.
Objective To compare the environmental microbiological and physical monitoring parameters between the temporary extended medical area and the normal area during the flexible allocation of ward, summarize the rule and find the potential risk points of infection control. Methods From April 10th to 23rd, 2023, prospective environmental microbial monitoring and physical parameter monitoring were carried out in a ward of Zhongnan Hospital of Wuhan University, and the monitoring results under different scenarios were compared and analyzed. Results In general, the carbon dioxide (CO2) concentration, particulate matter 2.5 (PM2.5) concentration, temperature, and relative humidity in the temporary medical area were better than those in the inpatient rooms (P<0.05), but there was no statistically significant difference in the amount of microorganisms detected on the surface of environmental objects or the hands of medical staff (P>0.05). After the start of the temporary medical area, the amount of microorganisms detected on the surface of environmental objects, CO2 concentration, and temperature in the inpatient rooms were higher than those in the temporary medical area (P<0.05), the PM2.5 concentration in the inpatient rooms was lower than that in the temporary medical area (P<0.05), and there was no statistically significant difference in the amount of microorganisms detected on the hands of medical staff or relative humidity between the two areas (P>0.05). Compared with those in the same area when the temporary medical area was not started, in the inpatient rooms after the start, the amount of microorganisms detected in the air, CO2 concentration, temperature, and relative humidity were lower (P<0.05), the amount of microorganisms detected on the surface of environmental objects and PM2.5 concentration were higher (P<0.05), and there was no statistically significant difference in the amount of microorganisms detected on the hands of medical staff between the two periods (P>0.05); in the temporary medical area after the start, the PM2.5 concentration was higher (P<0.05), the CO2 concentration and temperature were lower (P<0.05), and the differences in the relative humidity and amounts of microorganisms detected on the surface of environmental objects and the hands of medical staff between the two periods were not statistically significant (P>0.05). Regardless of whether the temporary medical area was activated or not, Filamentous fungi had the highest detection rates in air samples, and Staphylococcus epidermidis had the highest detection rates in both environmental surface samples and medical staff hand samples. Conclusion A series of environmental risks such as environmental microbial load and poor ventilation caused by temporary medical areas should be paid attention to.
