心脏瓣膜置换术后患者资源利用发展轨迹及其与风险感知的差异性分析
Trajectories of resource utilization and their differential associations with risk perception in patients after heart valve replacement
摘要
Abstract
Objective To explore the trajectories of resource utilization changes and their influen-cing factors in patients after heart valve replacement,and to analyze the correlation between different trajectories and risk perception.Methods A total of 194 patients with valvular heart disease were selected by convenience sampling.Questionnaires on resource utilization and risk perception were ad-ministered at the time points of postoperation(T1),before discharge(T2),1 month after discharge(T3),3 months after discharge(T4),and 6 months after discharge(T5).Latent class growth mod-eling,influencing factor analysis,and pairwise comparison by analysis of variance were employed for data analysis.Results Three resource utilization trajectories were identified:C1(significant in-crease group),C2(slow increase group),and C3(persistently moderate-low group).Significant differences were found among the trajectory classes in age(x2=16.255,P=0.012),education level(x2=13.761,P=0.032),social support(x2=11.657,P=0.020),and coping style(x2=21.045,P＜0.001).Logistic regression analysis revealed that age,education level,social support,and coping style were influencing factors of resource utilization trajectories after heart valve replacement(P＜0.05).Within 6 months after heart valve replacement(T1 to T5),risk perception scores showed anupward trend in all groups(C1:F=47.260,P＜0.001;C2:F=15.833,P＜0.001;C3:F=4.514,P=0.033).During theT1to T2 period,no significant difference in risk perception was observed among the groups.At T3,the risk perception scores of both the C1 and C2 groups were significantly higher than those of the C3 group(P＜0.01).During the T4 to T5 period,the risk perception score of the C1 group was significantly higher than those of the C2 and C3 groups(P＜0.001),and that of the C2 group was significantly higher than that of the C3 group(P＜0.01).Conclusion Resource utilization in patients after heart valve replacement presents three dynamic trajectories within 6 months postoperatively.The differences in resource utilization trajecto-ries are closely associated with patients' risk perception.关键词
