Key result
A body-mass index ≥25 was associated with increased risk of rehospitalization for thromboembolism within 3 months after total hip arthroplasty (OR 2.5; 95% CI 1.8-3.4).

May inform BMI-stratified VTE prophylaxis after THA in older adults; leaves open causal effects and need for prospective trials.
Case-Control (n=889)
What are the predictors of rehospitalization for symptomatic venous thromboembolism after total hip arthroplasty in older adults?
Odds Ratio: 2.5 (95% CI 1.8–3.4)
A body-mass index ≥ 25 increases the risk of VTE rehospitalization after total hip arthroplasty, while pneumatic compression in lower BMI patients and post-discharge warfarin are protective.
White et al. (2000) conducted a case-control in Venous thromboembolism after total hip arthroplasty (n=889). Body-mass index ≥25 vs. Body-mass index <25 was evaluated on Rehospitalization for thromboembolism (OR 2.5, 95% CI 1.8-3.4). A body-mass index ≥25 was associated with increased risk of rehospitalization for thromboembolism within 3 months after total hip arthroplasty (OR 2.5; 95% CI 1.8-3.4).
