ABSTRACT
Objective:To construct a virtual simulation training platform for peripheral inserted central catheter (PICC) catheterization and discuss its application in clinical training.Methods:A total of 118 nurses who attended the PICC professional and technical advanced training courses in a province in 2020 and 2021 were enrolled in this study. In 2020, the training was conducted in the form of theoretical teaching combined with practical training ( n=51), and in 2021, virtual simulation platform was introduced as a supplement on the basis of the original training ( n=67). SPSS 23.0 was used for independent-samples t-test to compare the theoretical and operational assessment results of the two years and evaluate the application effect of the platform. Through the satisfaction survey and learning log, the nurses' experience of using the platform was understood. Results:The theoretical performance and the operational performance of nurses who participated in the training in 2021 were (96.56±3.17) and (94.06±2.16) respectively, and the operational performance was better than that of nurses who participated in the training in 2020 ( t=-11.37, P<0.001), and the difference in theoretical performance was not statistically significant ( t=0.17, P=0.853). In 2021, 63 nurses (94.0%) who used the virtual simulation platform believed that the platform could assist to improve the training effect; 61 nurses (91.0%) expected the application of virtual simulation technology in the teaching and training of other knowledges. Conclusion:As a new teaching form, virtual simulation technology can significantly improve the training effect and satisfaction, and provide reference for the development of relevant teaching and training.
ABSTRACT
Objective:To understand the current situation and demand of intracavity electrocardiographic positioning technique training for PICC specialist nurses in Shandong Province, and provide a reference for further improving and improving the training of PICC specialist nurses.Methods:From July 7-23, 2019, a total of 903 PICC specialist nurses in Shandong Province were selected by the convenience sampling method. The nurses were investigated by the self-made general information questionnaire of PICC specialist nurses in Shandong Province and the training demand questionnaire of intracavity electrocardiographic positioning technique.Results:40.75% (368/903) PICC specialist nurses had participated in intracavity electrocardiographic positioning technique training; 84.27% (761/903) PICC specialist nurses thought it necessary to conduct intracavity electrocardiographic positioning technique training. PICC specialist nurses had various training on intracavity electrocardiographic positioning technique, the average content requirements were all above 4.67 points. The highest score of theoretical training content was the judgment of the relationship between catheter tip position and electrocardiogram P wave (4.80 ± 0.47), and the highest score of operation training content was the intracavitary electrocardiography guided PICC catheterization (4.74 ± 0.55). 94.24%(851/903) PICC specialist nurses hoped to achieve the goal of improving clinical nursing practice ability through intracavity electrocardiographic positioning technique training. Intravenous therapy specialist academic conference was the main hoped training form(76.85%, 694/903). Multiple regression analysis showed that the number of years of catheterization, job position and understanding of the technology were the influencing factors of PICC specialist nurses′ training needs for intracavity electrocardiographic positioning technique ( t = -3.73,3.12, -3.63, all P<0.05). Conclusions:The training rate of intracavity electrocardiographic positioning technique was low, but PICC specialist nurses had higher training requirements for intracavity electrocardiographic positioning technique. Managers should pay attention to the training of intracavity electrocardiographic positioning technique, and develop targeted training programs to further improve the clinical practice capabilities of the PICC specialist nursing team.
ABSTRACT
Objective To understand the effect of the general practitioners training in northern An-hui province, so as to provide a scientific basis for improving training strategies and measures. Methods In accordance with the requirements of Implementation of General Practitioners Training Program in Anhui Province, the training courses was designed, which includes the differences between general medicine and special medicine, general medicine service psychology, ethics related skills, general teaching skills, general clinical skills, and general practice policies, with a total of 32 credit hours. Participants were examined through the self-designed electronic questionnaire before and after the training. A total of 118 participants were involved in the training, and 109 of them were examined before the training, with a recovery rate of 92.4％. After the training, they were examined again, and the recovery rate was 100％. All data were analyzed by SPSS 17.0 software, and P<0.05 was considered statistically significant. Results Scores of the general medicine knowledge and skills after the training were higher than that before the training, and the difference was statistically significant (P<0.05). As for the course evaluation, the average score was over 4 in organiza-tion and management, training facilities, teacher knowledge, training materials, training methods and skills, while the average score was no more than 4 in training content and helping teaching. Conclusion The training achieves good results, and in the future, we should strengthen the training of teaching ability, thus further improving the effect of general practitioners training. Also, we should design the training content reasonably and pay attention to improve the quality and effectiveness of individual courses accordingly. What's more, we can use diversified teaching methods to further improve the teaching ability of general practitioners.
ABSTRACT
The aim of the paper is to review the research progress on the secondary metabolites from marine microorganisms in recent years and to summarize its application in antimicrobial activity. We have earched and collected the published articles which are focused on the secondary metabolites from marine microorganisms; analysed the structure and function of the secondary metabolites and summed up the antimicrobial activities of the production from marine microorganisms; in addition,investigated the mechanism of action about the antimicrobial activities of the secondary metabolites from marine microorganisms. The secondary metabolites from marine microorganisms have rich structural diversity and different mechanisms of action. Marine microorganisms have the potential to produce large numbers of bioactive metabolites, among which the antimicrobial substance is the most prominent,making it an important resource in the development of novel marine drugs.
