Postoperatively, the intervention group showed superior nutritional biomarkers (ALB, PA, Hb), shorter time to mobilization and hospital stay, better hip function (Harris score) and quality of life (SF-36), a lower DVT incidence (<i>p</i> < 0.05), and higher nursing satisfaction (<i>p</i> < 0.05).<h4>Conclusion</h4>The Caprini risk assessment model demonstrates predictive value for DVT risk in this population. This evidence concerns the gene GSTM1 and deep vein thrombosis.
