Summary
Preoperative deep vein thrombosis (DVT) in elderly hip fracture patients is predicted by female sex, active smoking, high Wells
Area of Science:
- Geriatric Medicine
- Vascular Surgery
- Orthopedic Surgery
Background:
- Deep vein thrombosis (DVT) is a significant complication in elderly hip fracture patients, potentially leading to pulmonary embolism.
- Preoperative DVT is a critical concern despite advancements in perioperative care.
Purpose of the Study:
- To identify risk factors for preoperative DVT in elderly patients with hip fractures.
Main Methods:
- Retrospective case-control study of hip fracture patients over 60 years old.
- Exclusion of patients with prior DVT or incomplete records.
- Logistic regression analysis to determine independent predictors of preoperative DVT.
Main Results:
- 5.1% of 454 eligible patients were diagnosed with preoperative DVT.
- Independent predictors identified: female sex (p=0.02), active smoking (p=0.01), Wells' score ≥ 2 (p=0.01), and elevated platelet-to-lymphocyte ratio (PLR) (p=0.05).
- The predictive model showed good discriminative performance (AUC=0.81).
Conclusions:
- Preoperative DVT is clinically relevant in elderly hip fracture patients.
- Female sex, active smoking, higher Wells' score, and elevated PLR are key independent predictors.
- Incorporating these factors can enhance preoperative risk stratification and optimize diagnostic imaging.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

578
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
