Influencing factors of venous thromboembolism in hospitalized patients of intensive care unit / 中国实用护理杂志

ABSTRACT

Objective To analyze the influencing factors of venous thromboembolism (VTE) in intensive care units, and provide evidence for corresponding clinical decisions. Methods A case-control study was carried out224 VTE patients admitted to the ICUs of tertiary hospitals in Kunshan from Nov. 2011 to Nov. 2016 were included in the case group, and 224 non-VTE patients admitted during the same period were randomly selected as the control. The patients' medical history, laboratory tests, prophylaxis and treatment of VTE, and other relevant data were retrieved. Logistic aggression analysis was utilized to identify the influencing factors of VTE in hospitalized critically ill patients. Results The univariate analysis showed that gender, age, hypertension, smoking, D-dimer, Caprini scaling, prophylaxis and treatment of VTE were associated with VTE. The multivariate analysis indicated that except hypertension, the other varieties were independent influencing factors of VTE in hospitalized critically ill patientsfemale ( OR=1.68, 95％CI1.09-2.61, P=0.02), higher age(OR=1.03, 95％CI1.01-1.04, P<0.01), smoking(OR=6.82, 95％CI1.70-27.46, P=0.007), smoking(OR=6.82, 95％CI1.70-27.46, P=0.007), D-dimer(OR=0.94, 95％CI0.92-0.96, P<0.01), higher Caprini scaling(OR=1.80, 95％CI1.33-2.44, P<0.01), prophylaxis and treatment of VTE(OR=0.34, 95％CI0.15-0.79, P=0.01). Conclusions Those ICU patients who are female, elder, with smoking history, have higher test value of D-dimer should be screened and assessed for VTE, and those with higher Caprini scaling should be given closer attention, and receive corresponding prophylaxis and treatment to reduce the formation of VTE and its damage.
