Prophylaxis for venous thromboembolism after total knee replacement (TKR) is standard of care. Two enoxaparin regimens are approved for thromboprophylaxis, one in the United States (30 mg twice daily [bid]) and another in the rest of the world (40 mg once daily [qd]). Data on frequency of utilization of these 2 regimens at discharge from US hospitals after TKR are not available.
We conducted a retrospective/descriptive analysis of the PharMetrics claims database to estimate the frequency of utilization of enoxaparin 40 mg qd compared to 30 mg bid after discharge for TKR from US hospitals.
Of the 44 552 TKR patients identified, 7198 had an outpatient claim for enoxaparin within 14 days postoperatively. The 40 mg strength of enoxaparin was prescribed more commonly (51%) than the 30 mg strength (46%).
Enoxaparin 40 mg qd is prescribed in approximately the same proportion of patients as the current Food and Drug Administration-approved regimen of 30 mg bid.
全膝关节置换术(TKR)后预防静脉血栓栓塞症是标准的治疗方法。两种依诺肝素方案被批准用于血栓预防,一种在美国(每天两次 30 毫克[bid]),另一种在世界其他地区(每天一次 40 毫克[qd])。关于 TKR 后从美国医院出院时这两种方案的使用频率的数据尚不可用。
我们对 PharMetrics 索赔数据库进行了回顾性/描述性分析,以估计在美国医院 TKR 出院后,与每天两次 30 毫克 bid 相比,依诺肝素 40 毫克 qd 的使用频率。
在确定的 44552 例 TKR 患者中,有 7198 例在术后 14 天内有依诺肝素的门诊索赔。依诺肝素 40 毫克的强度比 30 毫克的强度更常用(~51%)。
依诺肝素 40 毫克 qd 的处方与当前食品和药物管理局批准的 30 毫克 bid 方案的处方比例大致相同。
