Abstract:
Objective:To develop the risk assessment scale for deep vein thrombosis (DVT) in Intensive Care Unit (ICU) patients so as to provide a theoretical basis for clinical nurses to assess the risk of DVT in ICU patients.Methods:We drew up the initial entry pool of the scale, and revised the scale through expert letter inquiries. The diagnostic threshold was used to determine with the receiver operating characteristic (ROC) cure, and percentiles were used to determine risk levels. The reliability was analyzed using inter-rater reliability, internal consistency reliability and split-half reliability. The validity was analyzed with the content validity, structure validity and standard correlation validity.Results:The scale included 37 items. The optimal diagnostic threshold of the scale was 10, and the area under the ROC cure was 0.837 with a statistical difference ( P<0.001) . The risk levels of the scale were as follows, 10 to 11 were divided into low risk, 12 to 16 were divided into medium risk, and ≥17 was divided into high risk. The correlation coefficient of the inter-rater reliability of the scale was 0.967 with a statistical difference ( P<0.001) , and the Cronbach's α coefficient and the split-half reliability coefficient of the scale were 0.804 and 0.742 respectively. The content validity of the scale was 0.97, and the standard correlation validity was 0.665 with a statistical difference ( P<0.001) , and the Kaiser-Meyer-Olkin ( KMO) value was 0.533 with no statistical difference ( P>0.500) , and the χ 2 value of the Bartlett sphericity test was 1 849.43 also with a statistical difference ( P<0.001) . The cumulative contribution rate was 65.39%. Conclusions:This study initially developed a risk assessment scale for DVT in ICU patients, which provides a scientific and effective assessment tool for the development of DVT prevention and treatment in ICU patients.
