ABSTRACT
Objective:To investigate the assessment and occurrence of first-occured venous thromboembolism(VTE) among hospitalized patients.Methods:The clinical data of 6 532 surgical patients in Shenzhen Hospital, Peking University who were admitted from May 1, 2021 to June 30, 2021 were collected and analyzed retrospectively. The demographic data, Caprini score at admission and the incidence of VTE during hospitalization were analyzed by two independent sample t test and chi square test. Results:The Caprini score at admission of 6 532 patients was 1.81 ± 1.71. The number of cases in high, medium and low risks was 363 (5.6%), 1 189 (18.2%), 4 980 (76.2%), respectively. There was significant difference in VTE risk assessment scores and grades in different gender ( t=5.31, χ 2=48.31), length of stay ( F=195.21, χ 2=548.52) and hypertension ( t=17.07, χ 2=280.89), diabetes ( t=12.14, χ 2=51.18), smoking ( F=31.71, χ 2=53.23) and drinking ( F=18.78, χ 2=30.07) ( P<0.05). Forty-four(0.7%) patients got hospital-acquired VTE totally, among which, 24 cases (6.6%) were in high-risk, 14 cases (1.2%) were in medium-risk and 6 cases (0.1%) were in low-risk. What′s more, the top five VTE risky departments based on the assessment were not completely consistent with the top five departments with the highest incidence of VTE. Conclusions:The hospitalized patients are at high risk of VTE. The risk factors of diabetes, hypertension, smoking, drinking and other related factors should be included in the evaluation model. Meanwhile, the VTE risk assessment of in-patients should be emphasized and prophylactic treatments should be taken to reduce the incidence of VTE.
