Objective: By evaluating the relationship between deep vein thrombosis (DVT) in intensive care unit (ICU) non-surgical patients and Caprini venous thromboembolism risk assessment model (Caprini model for short), the predictive value of Caprini model in ICU non-surgical patients was analyzed. Methods: 200 ICU non-surgical inpatients in the first affiliated hospital of Jinan university from April to September 2019 were retrospectively analyzed. General data of patients and the number of new DVT events were collected, and Caprini model was used for scoring the risk of venous thromboembolism (VTE). Results: There were 31 patients with DVT, accounting for 15.50%, and 169 patients without new DVT (non-DVT). Caprini model score was 9.03±2.70 in patients with DVT, higher than that in patients without DVT (6.80±2.48, P<0.001). 24 (12.00%) non-surgical ICU patients were at high risk of VTE and 171 cases (85.50%) were at very high risk. Only one patient with DVT was at high risk of VTE (3.23%), while the other 30 patients were at very high risk of VTE (96.77%). There were 1 case in low risk of VTE (0.59%), 4 cases in medium risk (2.37%), 23 cases in high risk (13.61%) and 141 cases in very high risk (83.43%) in non-DVT group. There was no significant difference in VTE risk stratification between DVT patients and non-DVT patients (P=0.063). The receiver operating characteristic (ROC) curve was plotted by using Caprini model score to predict DVT. The area under the ROC curve was 0.731, and the 95% confidence interval was 0.663-0.791 (P<0.001). The optimal cut-off point was 7, the sensitivity was 74.19%, the specificity was 65.68% and Youden’s index was 0.3897. Conclusion: The incidence of high risk and very high risk of VTE in ICU non-surgical patients was high, and Caprini model could better predict the occurrence of DVT, so it was necessary to strengthen the nursing of ICU non-surgical patients and effectively prevent DVT.
