ABSTRACT
Objective:To explore the application effect of the "homogenization + individualization" teaching training model on the nursing refresher training of pediatric surgery.Methods:A total of 38 nursing students who took refresher training of pediatric surgery in West China Hospital of Sichuan University for 3 months from March 2017 to February 2020 were selected as the research objects. Before and after training, the differences in basic nursing operation assessment scores, overall nursing program application scores, and post competency scores were investigated. At the same time, after the training, the theoretical knowledge level of the trainees was assessed and the trainees' satisfaction with the training process was investigated. SPSS 26.0 was performed for paired t test. Results:The basic nursing operation scores, the overall nursing quality of the responsibility system and the post competency assessment scores of the trainees after the training were significantly better than those before the training [(92.99±2.46) vs. (94.96±2.71), t=-6.18, P<0.001; (94.82±2.12) vs. (96.16±1.82), t=-3.92, P<0.001; (79.89±5.10) vs. (88.16±4.29), t=-11.58, P<0.001]. Among the 18 teaching satisfaction items, the 3 items with the lowest scores were, in turn, giving certain affirmation to the trainee's work, the department teachers having training consciousness, and guiding students to solve difficulties. Conclusion:The "homogenization + individualization" training mode can effectively improve the basic operating skills, the overall nursing quality of the responsibility system and the post competency of the advanced nursing students of pediatric surgery, and achieve better teaching satisfaction.
ABSTRACT
Objective@#To identify the lifestyle pattern of adolescents in Guangzhou and to provide a scientific basis for targeted and individualized interventions for adolescents with different lifestyle pattern.@*Methods@#A survey was conducted by questionnaire among 12 540 students from 27 middle schools in the urban area of Guangzhou using a convenient sampling method. The latent class model (LCM) was used to identify lifestyle patterns of adolescents, and further analyses were conducted to compare differences in dietary habits and willingness to exercise among the different classes.@*Results@#Three lifestyle patterns were identified based on the latent class model: "high sweet snacks/excessive screen time, sleep and exercise deficiency group", 3 797 people, accounting for 30.3%; "low nutrition diet/severe sleep and exercise deficiency group", 2 745 people, accounting for 21.9%; "general diet/sleep and exercise deficiency group", 5 998 people, accounting for 47.8%. Adolescents of different classes had different perceptions of their eating habits and different degrees of willingness to participate in physical exercise, these differences were statistically significant(χ 2=671.54, Z=153.16, P<0.05).@*Conclusion@#The results of the latent class model showed that the three classes of adolescents had their own unique characteristics. It is necessary to inform them of their needs, provide guidance and implement targeted interventions according to the unique characteristics of the different lifestyle patterns in empirical work.
ABSTRACT
Objective To evaluate the effect of case-PBL method and case-PBL method combined with SPSS software on the teaching of medical statistics for medical undergraduates. Methods Students from two classes major in experimental medicine from Nantong University Xingling College were selected as Experimental Class 1 ( using case-PBL teaching ) and Experimental Class 2 ( using case-PBL teaching combined with SPSS software). Each class attended lessons for five times. The teachers would send cases for each lesson one week in advance, and students would form into groups to access information, learn and discuss independently. Representatives from groups spoke in class, members would complement and discuss, while teachers offered guidance, review, analysis and summary. We shortened the discussion time in the class, and added instructions on the operation steps of SPSS software for case analysis and how to interpret the analysis result correctly in Experiment Class 2 . The Control Class received traditional teaching . Questionnaires, process assessment and final assessment were used to evaluate teaching effectiveness. SPSS 21.0 software was used to implement variance analysis and chi-square test for comparison between groups. Results The scores of the two experimental classes were higher than those of the control class in the five process assessments ( P<0 . 05 ) . Experimental Class 2 was the best in three section process assessments including those of t-test, the rank sum test and the straight-line correlation (P<0.05). However, there was no difference in the theoretical test scores among the three classes (P=0.670). 94％-100％of the students in the two experimental classes believed that the teaching effects of the case-PBL method and case-PBL method combined with SPSS software were better than the traditional teaching method (P<0.05) in such areas as stimulating interest in learning, improving learning efficiency, etc. Students in Experimental Class 2 were more prone to think these methods improved teaching effect. Conclusion The case-PBL teaching combined with the application of SPSS software will further help students to systematically grasp the statistical knowledge and cultivate statistical practice ability . However , neither methods will improve students' theoretical test scores.
ABSTRACT
Objective To investigate and compare the effect of two kinds of transparent dressings in the use of fixed intravenous indwelling needle in restless patients in emergency first aid. Methods A total of 160 restless patients who were required to use intravenous indwelling needle were randomly divided into conventional dressing group and 3M dressing group by random digits table method, 80 patients in each group. The medical transparent dressings(Specification:6 cm × 7 cm) were used for the patients of conventional dressing group, and 3M dressings(Specification:6.5 cm×7.0 cm ) for 3M dressing group. The fixity time, number of cases intravenous indwelling needle detached, replaced time of transparent dressing, number of crimping cases were compared. Results For the conventional dressing group, fixity time was (19.67 ± 7.02) h, replaced time was (18.92 ± 6.58) h, 15 detached cases and 24 crimping cases happened. While for the 3M dressing group, fixity time was (41.64±17.79) h, replaced time was (41.11 ± 17.76) h, 4 detached cases and 7 crimping cases happened. The difference was statistically significant(t=-10.27,χ2=7.23, t=-10.48,χ2=11.56, all P<0.05). Conclusions 3M transparent dressing is suggested in fixing intravenous indwelling needle in restless patient in emergency first aid. It can ensure the use of intravenous indwelling needle during the period, effectively prevents the needle from detaching due to its good fixation effect.
