Population studies on the incidence of venous thromboembolism (VTE) in patients with active cancer are limited. An observational cohort study was undertaken to estimate the incidence of first and recurrent VTE. The source population consisted of all patients in the UK Clinical Practice Research Datalink, with additional information on hospitalisation and cause of death, between 2001 and 2011. A cancer-related clinical diagnosis or therapy within the 90 days before or after a VTE constituted an active-cancer-associated VTE. Incidence rates of first VTE among patients with active cancer and incidence rates of recurrent VTE during the 10-year observational period after a first VTE event were estimated. Incidence rates of all-cause mortality and age- and gender-specific mortality were also calculated. There were 6,592 active-cancer-associated VTEs with a total of 112,738 cancer-associated person-years of observation. The incidence rate of first VTE in patients with active cancer was 5.8 (95 % confidence interval 5.7-6.0) per 100 person-years. A first VTE recurrence was observed in 591 patients. The overall incidence rate for recurrence was 9.6 (95 % confidence interval 8.8-10.4) per 100person-years, with a peak at 22.1 in the first six months. Recurrence rates were similar after initial pulmonary embolism and after initial deep-vein thrombosis. The mortality risk after VTE was considerable, with 64.5 % mortality after one year and 88.1 % after 10 years. VTE in patients with active cancer is common and associated with high recurrence and mortality rates. Efforts are needed to prevent VTE and reduce recurrence, especially in the first year after VTE diagnosis.

To measure the per-event health plan costs for acute and follow-up treatment not directed by a clinical study protocol in a group of commercially insured patients in 2 managed care organizations following an incident hospitalization that included a diagnosis for a venous thromboembolism (VTE) event. A cohort of patients with an incident in-hospital VTE event, consisting of deep vein thrombosis (DVT), or pulmonary embolism (PE), or both DVT + PE, was retrospectively identified from the administrative claims databases of 2 large U.S. health care plans. Inclusion criteria were (a) an inpatient VTE event between January 1, 1998, and December 31, 2000, (b) no VTE diagnosis or anticoagulation therapy 3 months prior to the incident VTE in-hospital event, (c) at least 1 anticoagulation pharmacy fill following the incident hospital VTE, and (d) continuous health plan enrollment 3 months prior to and 6 months following the incident hospital VTE event. Total costs were reported on a per-event basis and consisted of the aggregated amount paid by the health plan to the provider after subtraction of member cost-share. Costs were collected separately, first for the incident VTE event for all patients identified and second for patients who had at least 1 of the following events in the follow-up period: bleed requiring or not requiring hospitalization, a recurrent VTE event requiring hospitalization, or a recurrent VTE and bleed (VTE + bleed) event requiring hospitalization. Costs were compared between incident diagnosis groups using multivariate generalized linear model techniques. A total of 2,147 patients (DVT=1,499 [69.8%], PE=373 [17.4%], DVT+PE= 275 [12.8%]) were identified (mean age=61.6standard deviation [SD] 16 years; 46.3% male) and were followed for an average of 21.3 (median, 19.2) months. Disease severity was high in these patients, including 59.2% with a history of or active malignancy. The prevalence of VTE was 2.04 per 100,000 study-eligible health plan members. For the incident VTE events, average costs were 7,712+/-18,339 US dollars (median, 3,131 US dollars) per incident DVT event; 9,566+/-13,512 US dollars (median, 6,424 US dollars) per PE incident event; and 12,200+/-24,038 US dollars (median, 6,678 US dollars) per incident DVT+PE event. Warfarin treatment following the incident VTE event was administered to 97.3% of patients for an average of 6.7 (median, 5.0) months at an average cost of 19.40 US dollars per patient per month. During the average period of 21.3 months, 534 patients (24.9%) experienced an average of 1.24 bleed or recurrent VTE events per patient that required hospitalization at a mean cost of 14,975 US dollars per event or 2,101 US dollars per patient per year. For patients with a bleed in the follow-up period that required hospitalization, average costs were 12,326+/-24,448 US dollars (median, 5,736 US dollars) per recurrent VTE; 15,339+/-52,029 US dollars (median, 4,999 US dollars) per bleed; or 24,085+/-65,411 US dollars (median, 10,185 US dollars) per recurrent VTE + bleed event. During the follow-up period, a total of 612 patients (28.5%) experienced 1,489 recurrent bleed events that did not require hospitalization, at an average cost of 239+/-386 US dollars (median, 95 US dollars) per event. There were no significant differences in mean total costs for all pair-wise comparisons between the 3 incident diagnosis groups. Of patients who experienced a VTE event during the incident hospital stay for any diagnosis, 1 in 4 experienced an average of 1.24 bleed or recurrent VTE events that required hospitalization in the 21 months of follow-up and incurred an average health plan cost of 14,957 US dollars per event. These data may be of interest to managed care decision makers when evaluating the cost impact of new therapies or providing more comprehensive anticoagulation management services for existing therapies.

Portal vein thrombosis is commonly associated with cirrhosis. The effect of alcoholic cirrhosis on portal vein thrombosis prevalence and mortality has not been well studied. We conducted a retrospective cohort study utilizing the 2000-2014 National Inpatient Sample Database. We included patients older than 18 years with decompensated cirrhosis without a history of liver transplantation or hepatocellular carcinoma. We further identified patients with alcoholic cirrhosis vs. non-alcoholic cirrhosis. Primary outcomes included the risk and mortality of portal vein thrombosis in alcoholic cirrhosis. Secondary outcomes included trends of portal vein thrombosis prevalence and mortality in alcoholic cirrhosis, implications of portal vein thrombosis on complications in alcoholic cirrhosis vs. non-alcoholic cirrhosis, and risk of venous thromboembolism in alcoholic cirrhosis. Among 1 892 271 patients with decompensated alcoholic cirrhosis, portal vein thrombosis prevalence was 1.3%. Alcoholic cirrhosis was associated with lower risk of portal vein thrombosis (odds ratio 0.76, P < 0.001) and venous thromboembolism (odds ratio 0.69, P < 0.001) compared to non-alcoholic cirrhosis. Portal vein thrombosis contributed to increased mortality (odds ratio 1.19, P < 0.001) in alcoholic cirrhosis. Portal vein thrombosis prevalence among alcoholic cirrhosis increased while mortality declined during the study period. Thrombotic events including portal vein thrombosis and venous thromboembolism were found in less frequent association with alcoholic cirrhosis compared with non-alcoholic cirrhosis. Despite this, the higher in-hospital mortality found among portal vein thrombosis with alcoholic cirrhosis should prompt careful consideration of management.
