| BackgroundOnce cardiac arrest occurred,it would cause irreversible damage to the patient's brain and other key organs within 4 to 6 min,therefore,Cardiopulmonary resuscitation(CPR)is the most basic and critical technique for saving lives.It could increase successful rescue rate and reduce pre-hospital death rate effectively,so that the first-time CPR played an irreplaceable role in first aid technologies.However,due to lack of awareness and ability of first aid,the public could not perform CPR so timely that more than 80% of patients have died clinically before medical personnel arrival.Therefore,urgent public training is needed to improve public awareness,knowledge and ability of CPR.Moreover,most of existing studies focusing on short-term training,haven't token it into account that knowledge and skills would decline over time,and no long-term training mechanism haven't been established.Most people,who had received relevant training,were consciously unable to correctly implement CPR so that patients could not obtain effective treatment.Therefore,the long-term and correct grasp of CPR knowledge and skills is a major issue that we need to take into consideration.ObjectiveThis study aims to use a combination of Internet platform and on-site training to build a training program for college students who are in a CPR program.By comparing the mastery and forgetting of students' CPR under different training methods,we could test the effectiveness of the program and explore applicability in training for CPR,providing experience and reference for popularizing first aid knowledge.Methods1.Using the cluster sampling method,362 freshmen of non-medical major in two engineering universities were selected to investigate the awareness and willingness to study cardiopulmonary resuscitation(CPR)in non-medical universities.318 students who met the inclusion criteria were randomly divided into experimental group and control group.2.In the control group,the training mode of free learning was adopted.The experimental group adopted the method of on-site training and Internet intervention to conduct training,that is,after on-site training,the task group enhanced the students undefined knowledge by means of WeChat or QQ Internet platform.After on-the-spot training,the students were strengthened by WeChat or QQ after class,and the PPT,pictures and teaching video materials edited by the task group were sent to each student in time.According to the memory rule revealed by the Ebbinghaus Forgetting Curve,the time of knowledge enhancement after on-the-spot training was arranged(1 day,2 days,4 days,7 days,15 days),and then the relevant knowledge was pushed forward every month for one year.Before training,immediately after training,one month,three months,six months,nine months,and twelve months after training,the students were investigated for cardiopulmonary resuscitation(CPR).3.SPSS19.0 statistical software was used for statistical data analysis and processing to compare the changes in knowledge and skill scores of students' CPR at different times.The measurement data was expressed as x ± s.The count data was expressed as the number of cases and the composition ratio test.The difference was statistically significant at P<0.05.Results1.The awareness rate of college students' CPR(25.71%)before training was low.The main sources of knowledge for CPR in college students were schoolteachers(25.90%),television(21.69%),first aid training classes or lectures(19.28%),and internet(19.28%).99.15% of the students believe that learning CPR is necessary.They expect to learn CPR from hospital's doctors and nurses(60.73%),arrange special classes by school(52.26%),and learn on CPR simulators(53.67%).University students frequently sailing on internet and were willing to learn related knowledge through the online platform(92.94%)2.There was no significant difference in gender and age between the two groups of students,P values were 0.903 and 0.997 respectively.There was no significant difference in knowledge scores between the two groups before training(P=0.138).There was no significant difference in knowledge scores between the two groups immediately after training(P=0.214).3.One month after training,students in the experimental group scored(30.89±7.91)higher than those in the control group(27.15±7.20),and the difference was statistically significant(P=0.000).The knowledge score of the experimental group(27.97±7.13)was higher than that of the control group(24.33±7.44)3 months after the training,and the difference was statistically significant(P=0.000).The knowledge score of the experimental group(27.69±8.19)was higher than that of the control group(23.76±6.58)6 months after the training,and the difference was statistically significant(P=0.000).The knowledge score of the experimental group(26.96±7.42)was higher than that of the control group(22.62±5.70)9 months after the training,and the difference was statistically significant(P=0.000).The knowledge score of the experimental group(24.66±7.05)was higher than that of the control group(21.38±7.34)12 months after the training,and the difference was statistically significant(P=0.000).4.There was no statistically significant difference between the two groups in the frequency,depth,location and technique of instant chest compressions after training(P=0.465).After 1 month,3 months,6 months,9 months and 12 months of training,there was a statistically significant difference(P=0.000)in the correct times of 4 items of chest compressions.5.Students were assessed for skills in the 12 months after training.In the experimental group,the correct rate of pressing(27.16%)was higher than that of the control group(20.02%),and the difference was statistically significant(P=0.000).The artificial respiration rate(35.33%)of the experimental group was higher than that of the control group(24.00%),and the difference was statistically significant(P=0.000).6.Students in the experimental group were satisfied with the Internet & on-site training.Students are more satisfied with the arrangement of training teachers,training forms,and training time.ConclusionsThe on-site & Internet training method can improve the learners' mastery of the knowledge and skills of CPR,slow down the speed of forgetting.It has a positive impact on the long-term maintenance of knowledge and skills of CPR. |
