| Objective:1.To understand the current situation of on-site knowledge popularization of cardiopulmonary resuscitation(CPR)among non-medical workers in hospitals,and to analyze the reasons affecting their mastery level,so as to provide the basis for making targeted training plans for hospitals.2.To explore the application effect of the real-time feedback device of CPR based on scenario simulation exercise and the training mode of reflective practice in CPR training for non-medical workers in hospitals,so as to find a training method suitable for non-medical workers in hospitals to master CPR on-site.Methods:The subject is divided into two parts:the first part is a cross-sectional survey on the knowledge of CPR on-site;the second part is an experimental study on training of CPR on-site.A self-designed questionnaire was used to investigate 326 non-medical workers in our hospital.126 non-medical workers were randomly selected from the non-medical workers who had been surveyed by random number table method.According to their working areas,they were randomly divided into three groups:A,B and C(41 in group A,40 in group B,45 in group C).A was a training group of scenario simulation exercises,and B was a training group of scenario simulation exercises+reflective practice training.Group C is scenario simulation exercises+real-time feedback device+reflective practice training group.After training,knowledge and skills of the three groups are assessed,and the results of assessment and quality monitoring of the three groups are compared.All the data were analyzed by SPSS 21.0 software.The measurement data were expressed by mean±standard deviation(x?s),the comparison between the two groups of data obeyed normal distribution using two independent samples t-test,the comparison of theoretical results before and after training using paired samples t-test,the comparison of data between multiple groups using single factor analysis of variance(ANOVA test);The counting data described by rate(%)and compared byx~2 test,and the influencing factors were analyzed by multiple linear regression and Pearson's method carry out correlation analysis.All the tests showed significant difference with P<0.05.Results:1.Current Situation Survey1.1 A total of 326 questionnaires were sent out,326 questionnaires were recovered,the recovery rate was 100%,9 invalid questionnaires were excluded,and 317 valid questionnaires remained,the effective rate was 97.23%.1.2 Among 317 hospital non-medical workers,the highest score was 100,the lowest score was 35,the average score was(60.60±13.84),136(42.9%)were below 60,40(12.6%)were above 80,and the correct rates of press depth and press frequency were the lowest,28.6%and 12.3%respectively.1.3 The survey of training intention showed that 91.8%of non-medical workers believed that it was necessary for hospitals to train on-site CPR,95.6%of them were willing to receive training;most non-medical workers(47.2%)believed that on-site CPR should be trained every six months,and the training methods of operation instruction(67.3%)and scenario simulation exercise(52.9%)were more popular than others;single training method(71.3%)is the most common problem in the past training;compared with theoretical knowledge,they hope to improve their operational skills(87.5%)and emergency psychology(60.6%).1.4 For the main reasons of not mastering CPR,44.8%thought that they had not received formal training;26.5%thought that they had not strong learning consciousness;17.1%thought that they could not find a way to learn;10.4%thought that they were too busy to work,and a small part(1.3%)was the other reasons,which could be ignored.1.5 Multivariate analysis showed that the knowledge scores of non-medical workers in elevator room,security,canteen,accounting department and fire fighting were significantly higher than those in cleaning(the beta values were 10.25,10.79,14.95,18.11 and 18.49,respectively);the knowledge scores of trained persons were significantly higher than those of untrained persons(the beta value was 8.88);the knowledge scores of those who experienced emergency rescue scenes were higher than those who did not experience emergency rescue scenes,the beta value was 3.07.Departments,whether trained or not,and whether they experienced emergency rescue scenarios were the influencing factors of knowledge mastery level(P<0.05).2.Analysis of Training Effectiveness2.1 There was no significant difference among the three groups after training(P>0.05),but there was a significant improvement compared with before training(P<0.05).2.2 After training,the scores of skill assessment in group C>group B>group A.Group B were higher than those in group A in five links:calling for help,judging breath,judging breath and pulse,pressing unbiased,avoiding excessive ventilation(P<0.05);the scores in frequency and depth of pressing in group C were higher than those in group B,with significant difference(P<0.05).2.3 The results of quality test were as follows:In terms of the pressing frequency,group C was superior to group B and group A,with pressing frequency(110.31±6.56)vs.(121.55±10.46),(122.07±9.86),with statistically significant differences(P<0.05).As for the depth of pressing,group C was superior to group B and group A,with the depth of pressing(5.37±0.27)cm vs.(4.09±5.09)cm and(4.30±1.04)cm respectively,and the difference was statistically significant(P<0.05).In terms of thoracic recoil,group C was superior to group B and A,with the number of stasis(18.13±5.13)vs.(31.53±6.12),(33.22±4.61),and the difference was statistically significant(P<0.05).The pressing interruption time of group A,B and C was(44.62±3.41)s,(44.69±3.49)s,(44.75±3.45)s,and the difference was not statistically significant(P>0.05).In terms of ventilation,group B and C were superior to group A,with the average ventilation quantity(626.25±89.66)ml,(600.98±85.41)ml vs.(723.2±138.07)ml,showing statistically significant differences(P<0.05).Moreover,the pressing frequency was negatively correlated with the depth of pressing(r=-0.799,p<0.01),and the pressing frequency was positively correlated with the number of retention(r=8.873,p<0.01).Conclusion:1.Hospital non-medical workers have a low level of on-site CPR knowledge and a great demand for training.2.Hospitals should pay more attention to the training of non-medical workers in cardiopulmonaryresuscitationandmobilizetheirenthusiasmforlearning cardiopulmonary resuscitation.According to the training willingness of trainees and the factors affecting their mastery level,they should formulate targeted routine training plans and adopt flexible and diverse training methods to train them.3.The training mode of CPR real-time feedback device+reflective practice can optimize some links of CPR skills training for non-medical workers in hospitals and improve the overall quality of training,which is worthy of further promotion and implementation. |
