Effects Of Trans-theoretical-model-based Health Education On Health Behaviors Of Patients After Percutaneous Coronary Intervention

Aim: The Trans-theoretical Model (TTM) combined with Motivational Interview (MI)method, strengthens the patients’ self-efficacy after percutaneous coronaryintervention(PCI), and helps the patients to change four types of lifestyle (includingsmoking, lack of physical exercise, high salt and fat intake) so as to prevent coronaryartery restenosis and improve the quality of life of patients and provide the scientific basisand implementation plan for developing and improving the health education plan ofpatients after PCI.Methods: This study was a randomized, controlled single-blind and prospectivetracking intervention study. Patients after PCI were recruited in cardiovascular wards in ahospital of Suzhou. They were divided into two groups based on the randomized table. Theexperimental group received the TTM-based intervention using motivational interviewmethod while the control group received the conventional intervention. There were twoparts of the intervention given to the subjects in the experimental group. The subjects in theexperimental group received individual interview and educational materials consistent withthe interview content when they were being hospitalized and received the telephoneintervention after discharge. The changes in smoking, physical exercise, salt and fat intakeand self-efficacy, blood pressure, waist circumference, the quality of life were comparedbetween two groups one month, two months, three months and six months after theirdischarge respectively. All the data were input and analyzed using SPSS16.0software.Results:164subjects were divided into experimental group and control group by therandomized method, with82patients in each group.The results revealed that the stage ofchange for quitting smoking was higher (P>0.05one month after discharge, P<0.05twomonths, three months and six months after discharge) and the daily cigarette consumptionwas less (P<0.05) in the experimental group after intervention. The stage of change of physical activities was higher (P<0.05), and the frequency and duration of physicalactivities was higher in the experimental group (P<0.01). Thus, significant difference wasfound between the two groups. The subjects in the experimental group showed higherreadiness for change (P<0.01) and consumed less salt and fat than the control group(P<0.01). The blood pressure was lower in the experimental group (P<0.01six monthsafter discharge) and the systolic blood pressure lowered9.5mmHg. The subjects in theexperimental group have a smaller waist circumference(P<0.05); after intervention generalself-efficacy and the quality of life in the experimental group were obviously higher thanbaseline and those of the control group (P﹤0.01).Conclusions: The TTM-based intervention combined with MI applied in behaviormodification of patients after PCI can improve self-efficacy level, effectively promote theirlifestyle changing, thus improving their quality of life. The findings provide means for thenurses to find an effective way to help patients make behavior modification.
