Abstract:
Objective:To compare the predictive values between 4 risk assessment scales for deep venous thrombosis (DVT) in patients with pelvic or acetabular fracture.Methods:The clinical data of 235 patients with pelvic or acetabular fracture were retrospectively analyzed who had been admitted to Xi'an Honghui Hospital from July 2014 to July 2018. They were 168 males and 67 females, aged from 18 to 90 years (average, 43.5 years). They were divided into a DVT group and a DVT-free group according to the results of vein ultrasongraphy. The RAPT, Caprini, Wells, and Autar scales were used respectively to assess the risk of DVT in the patients. The 2 groups were compared in terms of the scores of the 4 scales. After the receiver operating characteristic curve (ROC) was drawn and the area under the ROC curve (AUC) was calculated, the predictive values of the 4 scales were evaluated for lower limb DVT in the patients with pelvic or acetabular fracture.Results:Of the 235 patients, 104 (44.3%) had DVT. There was no statistically significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The DVT group scored significantly higher in RAPT, Wells and Autar scales than the DVT-free group( P<0.05). The AUCs for the RAPT, Caprini, Wells, and Autar scales were respectively 0.84±0.02, 0.65±0.05, 0.81±0.02 and 0.72±0.03, showing significant differences ( F=1.254, P=0.031). The AUCs for RAPT and Wells scales were significantly higher than those for Caprini and Autar scales, and the AUS for Autar scale was significant higher than that for Caprini ( P<0.05). The sensibilities for RAPT, Caprini, Wells and Autar scales were respectively 94.0%, 65.0%, 90.6% and 84.0% while the specificities for them 62.1%, 51.8%, 67.2% and 32.5%. Conclusion:Although all the 4 scales have a certain predictive value for the DVT risk in patients with pelvic or acetabular fracture, RAPT and Wells scales are more valuable.
