Specific causal validation of nursing diagnosis Risk for thrombosis: A case–control study

Purpose This study aims to perform specific causal validation of nursing diagnosis Risk for thrombosis (00291) of the NANDA International (NANDA‐I) classification. Methods This is a case–control study conducted in a university hospital from January to October 2020. A total of 516 adult patients were included—344 in the Case Group (with venous or arterial thrombosis evidenced by imaging) and 172 in the Control Group (without thrombosis). Statistical analysis was performed by univariate and multivariate logistic regression test, and odds ratios were calculated to measure the effect of exposure between groups. The study was approved by the Research Ethics Committee. Findings The patients were predominantly female and aged 59 ± 16 years. In the univariate logistic analysis, five risk factors were significantly associated with thrombosis, two at‐risk populations and 12 associated conditions. In the multivariate regression model, the following risk factors remained independently associated (p
