Inpatient Resource Use and Cost Burden of Deep Vein Thrombosis and Pulmonary Embolism in the United States

PURPOSE Venous thromboembolism (VTE), which comprises deep vein thrombosis (DVT) and pulmonary embolism (PE), is associated with significant morbidity and mortality. VTE frequently leads to hospitalization and represents a considerable economic burden to the US health care system. However, little information exists on the duration of hospitalization and associated charges among patients with an admitting or primary diagnosis of DVT or PE. This study assessed the charges associated with hospitalization length of stay in patients with DVT or PE discharged from US hospitals in 2011. METHODS Using data from the Nationwide Inpatient Sample of the Healthcare Utilization Project database, this analysis examined hospital length of stay and associated charges in patients with DVT or PE discharged from US hospitals in 2011. Both initial and subsequent hospitalizations were analyzed. FINDINGS DVT was responsible for fewer hospitalizations than PE. In 2011, among 330,044 patients with VTE discharged from US hospitals, 143,417 had DVT and 186,627 had PE. Mean length of stay for patients with DVT was 4.7 days (median, 3.9 days) compared with 5.1 days (median, 4.5 days) for patients with PE. For initial hospitalizations, the mean (SE) charge amounted to

214) for PE. Older patients with PE incurred greater hospital charges than younger ones, and for both DVT and PE patients, women incurred greater charges than men. Of 31,463 patients admitted to the hospital with PE, 4.0% had a subsequent admission, which was more costly than the initial admission. Many patients with both DVT and PE were discharged to specialist nursing facilities, indicating continuing posthospitalization charges. IMPLICATIONS Hospital stays for DVT and PE represent a substantial cost burden to the US health care system. Health care systems have the potential to reduce the clinical and economic burden of VTE by ensuring that evidence-based, guideline-recommended anticoagulation therapy is adhered to by patients with an initial VTE. Appropriate anticoagulant therapy and continuity of care in these patients may reduce the incidence and frequency of hospital readmissions and VTE-related morbidity and mortality and have a potential effect on health care resources.

Dyspepsia and disease burden among patients with atrial fibrillation.

PURPOSE Published evidence on quality-of-life (QOL) outcomes and health care costs in patients with postthrombotic syndrome (PTS), a common and difficult-to-diagnose complication of venous thromboembolism (VTE), is reviewed. SUMMARY Occurring in as many as 70% of patients with VTE, PTS remains a challenging and costly disorder, partly due to the lack of a standard diagnostic definition and varying classification systems. Searches of Medline and EMBASE identified 12 articles on humanistic and economic outcomes associated with PTS. The results of U.S. and international studies indicate that PTS is a key determinant of long-term QOL among patients with VTE. In one large study, 37% of patients with VTE developed PTS within two years of a diagnosis of deep venous thrombosis (DVT), and 4% developed severe PTS, with the occurrence of PTS linked to clinically relevant declines in measures of physical and mental health. Research indicates that the economic burden of PTS in the United States may be as high as

200 million annually. Recent progress in efforts to develop standard PTS terminology may facilitate the dissemination of clear consensus guidelines to assist in timely PTS detection and optimal care. CONCLUSION Appropriate measures to decrease PTS-related burdens may include the prevention of DVT, clear diagnostic criteria for PTS, and an education campaign aimed at increased standardization in the management of DVT. Gaps in the current understanding of the risk factors, diagnostic criteria, preventive strategies, and even treatment modalities for PTS hamper the ability of clinicians to employ measures that could reduce the occurrence of this disorder and the associated morbidity.

Association between anticoagulant treatment duration and risk of venous thromboembolism recurrence and bleeding in clinical practice

Abstract Objective: Benefits of anti-coagulation for venous thromboembolism (VTE) prevention in total hip and knee arthroplasty (THA/TKA) may be offset by increased risk of bleeding. The aim was to assess in-hospital risk of VTE and bleeding after THA/TKA and quantify any increased costs. Methods: Healthcare claims from the Premier PerspectiveTM Comparative Hospital Database (January 2000–September 2008) were selected for subjects ≥18 years with ≥1 diagnosis code for THA/TKA. VTE was defined as ≥1 code for deep vein thrombosis or pulmonary embolism. Bleeding was classified as major/non-major. Incremental in-hospital costs associated with VTE and bleeding were calculated as cost differences between inpatients with VTE or bleeding matched 1:1 with inpatients without VTE or bleeding. Results: A total of 820,197 inpatient stays were identified: 8042 had a VTE event and 7401 a bleeding event (2740 major bleeding). The risks of VTE, any bleeding, and major bleeding were 0.98, 0.90, and 0.33/100 inpatient stays, respectively. Mean incremental in-hospital costs per inpatient were
