Analysis of risk factors impacting antiplatelet medication adherence following stenting for atherosclerosis obliterans and development of prediction model / 中国实用护理杂志

ABSTRACT

Objective:To explore the risk factors of antiplatelet drug compliance after stent implantation in patients with lower extremity arteriosclerosis obliterans, and to construct an online prediction model tool.Methods:Retrospective analysis of the clinical data of patients with lower extremity arteriosclerosis obliterans who received lower extremity arterial stent implantation in Department of Vascular Surgery, Provincial Hospital Affiliated to Shangdong First Medical University from January 2019 to January 2021 was carried out. 90 patients with poor compliance and 90 patients with good compliance were selected into the observation group and the control group, respectively. Univariate analysis was used to screen the influencing factors of antiplatelet drug compliance, and the variables with statistical significance were substituted into the binary Logistic regression to carry out independent risk factor test to screen the risk factors of cross-over antiplatelet drug compliance and establish the prediction model.Results:Married ( OR = 0.316, 95% CI 0.135-0.738), number of follow-up visits during the follow-up period ( OR = 0.866, 95% CI 0.760-0.987), the amount of medication ( OR = 0.755, 95% CI 0.654-0.919) were the protective factors for the compliance of antiplatelet drugs in patients with lower extremity arteriosclerosis obliterans after stent implantation. Advanced age ( OR = 1.136, 95% CI 1.066-1.211), male ( OR = 3.727, 95% CI 1.533-9.060), junior high school and below education level ( OR = 4.949, 95% CI 1.501-16.313), the average monthly income less than 3 000 yuan ( OR = 15.774, 95% CI 4.487-55.495) and the monthly expenditure on medicine more than 500 yuan ( OR = 15.323, 95% CI 3.527-66.569) were the risk factors for the compliance of antiplatelet drugs in patients with lower extremity arteriosclerosis obliterans after stent implantation. The consistency index of this prediction model was 0.895, the area under the ROC curve was 0.875. Conclusion:The antiplatelet medication adherence prediction model established has high accuracy and good clinical application values.
