Study On Effects Of Timing-Theory Based Smoking Cessation Intervention In Patients Of Coronary Heart Disease

Objective:Establish a smoking cessation intervention program in the all phases of coronary atherosclerotic cardiopathy by the frame of Timing Theory and evaluate the impact of such interventions on the degree of smoking dependence,smoking urges and study the impact of smoking cessation on the quality of life of patients who suffered from coronary heart disease.So as to provide a theoretical basis for implementing effective smoking abstinence measures,promote smoking-quitting in patients with ischemic heart disease,to promote secondary prevention and cardiac rehabilitation.Methods:By using convenient sampling methods,93 patients with coronary heart disease who were hospitalized in two respective departments of cardiology at a Class A tertiary hospital in Nanchang City from August to September in 2022 were selected as the study subjects.Two departments were randomly divided into an intervention group and a control group,with 46 patients in the intervention group and 47 patients in the control group.The control group received brief smoking cessation intervention,as well as routine health education and disease following,the intervention group obtained special smoking cessation intervention based on Timing Theory on the basis of control group.Data of two groups were collected at the time when patients were admitted to hospital,1 month after discharge,and 6 months after discharge,included Fagerstrom Test of Nicotine Dependence(FTND),Questionaire on Smoking Urges-Brief(QSU-Brief),the status of every patient’s smoking cessation,the Seattle Angina Questionaire(SAQ)and 36-item Short-Form Health Survey(SF-36),to evaluate the effectiveness of this intervention plans for CHD patients.Results:1.Before the interventionThe basic information for these two study groups includes general data,Fagerstrom Test of Nicotine Dependence(FTND),Questionaire on Smoking UrgesBrief(QSU-Brief),all dimensions of the Seattle Angina Questionaire(SAQ)and36-item Short-Form Health Survey(SF-36)showed no statistically significant difference in the evaluation(P>0.05).2.After the intervention(1)Score of FTND: Between-group comparison: The FTND scores of the two groups of study subjecs at the time of 1 and 6 months after they discharge from hospital was different(P<0.05),and the intervention group had better results than the control group.Intragroup comparison: There was a significant difference(p<0.001)in both the intervention group and the control group at three time points;Schierer-RayCare test: smoking cessation intervention has significant Main effect(H=15.150,p<0.001),time effect(H=58.876,p<0.001)and interaction effect(H=6.255,p<0.05)on tobacco dependence in patients with CHD.(2)Score of QSU-Brief: Between-group comparison: There was a difference in the scores of QSU-Brief between the two groups of patients at the time of 1 and 6months after they discharge from hospital(P<0.05),and the results of the intervention group were better than those of the control group during the same period.Intragroup comparison: There was statistically significant difference in scores of QSU-Brief within both groups at three time points(p<0.001);Schierer-Ray-Hare test: smoking cessation intervention has significant main effect(h=34.755,p<0.001),time effect(h=51.633,p<0.001)and interaction effect(h=6.291,p<0.05)on patients with CHD.(3)Smoking cessation status: There was a significant difference in smokequitting rates between the two groups of patients at the time of 1 and 6 months after discharge(P<0.05),and the results of the intervention group was better than the control group during the same period.The smoke-quitting rate after1 month after discharge: 67.40% in the intervention group and 42.60% in the control group(P<0.05);The smoking cessation rate after 6 months after discharge: 56.50% in the intervention group and 31.90% in the control group(P<0.05).(4)Score of SAQ: Between-group comparison: There were differences in the all dimensions of SAQ between the two groups of patients at the time of 1 month and 6months after discharge(P<0.05),and the efficacy of the intervention group was better than that of the control group.Intra-group comparison: There was a significant difference in all dimensions of SAQ between the intervention group and the control group at the three points of time(p<0.001);Schierer-Ray-Hare test: smoking cessation intervention plan shows significant main effect(P<0.05)and time effect(P<0.001)on scores of every dimension of SAQ of patients with CHD(P<0.05),,but only the dimension of Physical Limitation shows interaction effect(P<0.01);(5)Score of SF-36: Between-group comparison: There was a difference in every dimension of SF-36 between the two groups of patients at the time of 1 month and 6months after discharge(P<0.05),and the results of the intervention group were better than those of the control group.Intra-group comparison: There was a significant difference in all dimensions of SF-36 in both intervention group and the control group at three time points(P<0.001);Schierer-Ray-Hare test: smoking cessation intervention shows a significant Main effect(P<0.05)and time effect(P<0.001)in all dimensions of SF-36,while only the 2 dimension of Social Functioning and Vitality shows interaction effect(P<0.05).Conclusion:The application of smoking cessation intervention based on Timing-Theory can improve the degree of nicotine dependence and smoking urges in patients with CHD to some extent,increase smoke-quitting rate,improve patients’ quality of life and prognosis,and provide reference value for clinical nursing interventions.
