Influence of the duration of hospital length of stay on frequency of prophylaxis and risk for venous thromboembolism among patients hospitalized for acute medical illnesses in the USA
BackgroundWe evaluated whether the duration of hospital stay influences venous thromboembolism (VTE) prophylaxis patterns and VTE risk during hospitalization and post-discharge among patients hospitalized for acute illnesses in the USA.MethodsPatients hospitalized for acute illnesses were identified from the US MarketScan Commercial and Medicare databases (January 1, 2012-June 30, 2015). Patients were stratified by index hospital length of stay (LOS), with study groups with 1-3 day, 4-6 day, and ≥7 day LOSs. Use of VTE prophylaxis and VTE event rates during and after hospitalization (6-month follow-up) were evaluated.ResultsOf the overall population, 8647 had a 1-3 day LOS, 5551 had a 4-6 day LOS, and 3697 had a ≥7 day LOS. A greater proportion of patients with a 1-3 day LOS (66.2%) did not receive any VTE prophylaxis in comparison to patients with a 4-6 day LOS (55.0%) and ≥7 day LOS (48.8%; p<0.001). Proportions of patients with VTE events during the index hospitalization increased with longer hospital LOS (1-3 day LOS: 0.5%; 4-6 day LOS: 1.3%; ≥7 day LOS: 5.4%), as did proportions of patients with VTE events during the 6-month follow-up (1-3 day LOS: 2.4%; 4-6 day LOS: 2.7%; ≥7 day LOS: 4.2%).ConclusionAmong this study population of hospitalized acutely ill patients in the USA, VTE pharmacologic prophylaxis was underutilized, regardless of the duration of hospital stay. However, the risk for VTE events was substantial, with nearly 10% of those with a ≥7 day LOS having suffered a VTE event within 6 months

Venous Thromboembolism Prophylaxis and Risk for Acutely Medically Ill Patients Stratified by Different Ages and Renal Disease Status
The objectives of this study were to examine venous thromboembolism (VTE) prophylaxis patterns and risk for VTE events during hospitalization and in the outpatient continuum of care among patients hospitalized for acute illnesses in the United States with stratification by different age groups and renal disease status. Acutely ill hospitalized patients were identified from the MarketScan databases (January 1, 2012-June 30, 2015) and grouped by age (<65, 65-74, ≥75 years old) and whether or not they had a baseline diagnosis of renal disease, separately. Of acutely ill hospitalized patients, 60.1% (n = 10 748) were <65 years old, 15.7% (n = 2803) were 65 to 74 years old, and 24.3% (n = 4344) were ≥75 years old; 32.9% (n = 5892) had baseline renal disease. Among the study cohorts, the majority of patients received no VTE prophylaxis regardless of age or baseline renal status (52.1%-63.6%). Rates of VTE during hospitalization and in the 6 months postdischarge were 4.7%, 4.6%, and 4.5% for patients <65, 65 to 74, and ≥75 years old, respectively, and 6.3% and 3.8% for patients with and without baseline renal disease. The risk for VTE was elevated for 30 to 40 days after index admission regardless of age and renal disease status

Impact of warfarin persistence on health-care utilization and costs among patients with atrial fibrillation managed in anticoagulation clinics in the United States
Warfarin is a recommended therapy to reduce the risk of stroke in patients with nonvalvular atrial fibrillation (NVAF). The objectives of this study were to identify potential factors associated with warfarin persistence and evaluate the impact of warfarin persistence on health-care resource utilization and costs among patients with NVAF in the United States. Patients (18 years) with 1 inpatient or 2 outpatient diagnoses of AF without valvular disease were identified from an electronic medical record database (January 1, 2004, to January 31, 2015). The patients with NVAF were grouped into 2 cohortspersistent with warfarin therapy and not persistent (warfarin discontinuation i
Frequency of hospital readmissions for venous thromboembolism and associated hospital costs and length of stay among acute medically ill patients in the US
Objectives: This study evaluated the frequency of hospital readmissions for venous thromboembolism (VTE) and the associated costs and length of stay (LOS) among acute medically ill patients in the US using a real-world claims database analysis. Methods: Patients (≥40 years of age) at risk of VTE due to hospitalization for acute medical illnesses, based on primary hospital discharge diagnosis codes, were identified from the MarketScan databases between July 1, 2011 and March 31, 2015. Patients were required to have continuous insurance enrollment in the 6 months prior to initial (index) hospitalizations (baseline period) and in the 6 months after hospital discharge (follow-up period). The proportions of patients with VTE-related (diagnosis at any position) and VTE as primary diagnosis hospital readmissions during the follow-up period were evaluated. The associated costs and LOS for such readmissions were also determined, as well as time to VTE-related readmissions. Results: Of the study population (n = 12,785; mean age = 68.3 years), most were hospitalized primarily for infectious diseases (35.2%), followed by respiratory diseases (27.9%), cancer (15.7%), heart failure (11.8%), ischemic stroke (8.1%), and rheumatic diseases (1.4%). Of the overall study population, 2.1% (n = 268) had a VTE-related hospital readmission in the 6 months following discharge of their index hospitalization, of which 36.6% (n = 98) were for a primary diagnosis of VTE. Approximately 25.4% of the VTE-related hospital readmissions occurred within the first 30 days of discharge and 58.2% within 90 days. The mean cost for a hospital readmission with a primary diagnosis of VTE was 14,719 and $23,305, respectively. Conclusions: Among this study population of patients hospitalized for acute medical illnesses, some experienced a VTE event requiring re-hospitalization, with 25% occurring within the first 30 days after hospital discharge
