Abstract
BACKGROUND We previously determined good agreement and high specificity of the International Society on Thrombosis and Haemostasis (ISTH) definition of pulmonary embolism (PE)-related death among an expert central adjudication committee (CAC). CACs are often composed of experts in the corresponding research field. Involving physician trainees in CACs would allow investigators to divide the workload and foster trainees' research experience. OBJECTIVE To evaluate the accuracy of the ISTH definition of PE-related death for PE- versus non-PE-related deaths as confirmed by autopsy and its interrater agreement among physician trainees. METHODS This retrospective autopsy cohort included all patients with PE-related deaths between January 2010 and July 2019 as well as patients who died in 2018 from a cause other than PE at the New York-Presbyterian Hospital. Based on premortem clinical summaries, two physician trainees independently determined the cause of death using the ISTH definition of PE-related death. We calculated the sensitivity and specificity of the ISTH definition to identify autopsy-confirmed PE-related death and its interrater agreement. RESULTS Overall, 126 death events were adjudicated (median age, 68 years; 60 [48%] women), of which 29 (23%) were due to PE, as confirmed by autopsy. Sensitivity and specificity of the ISTH definition for autopsy-confirmed PE-related death was 48% (95% CI, 29-67) and 100% (95% CI, 96-100), respectively. Interrater reliability for PE-related death was good (percentage agreement, 93%; 95% CI, 87-96, Cohen's Kappa, 0.67; 95% CI, 44-85). CONCLUSION Our findings are consistent with our previous validation study. They further support the use of the ISTH definition of PE-related death and revealed high agreement between adjudicators with varied experience.

Long-term risk of recurrent venous thromboembolism among patients receiving extended oral anticoagulant therapy for first unprovoked venous thromboembolism: A systematic review and meta-analysis.

Abstract
BACKGROUND The long-term risk for recurrent venous thromboembolism (VTE) during extended anticoagulation for a first unprovoked VTE is uncertain. OBJECTIVES To determine the incidence of recurrent VTE during extended anticoagulation of up to 5 years in patients with a first unprovoked VTE. METHODS MEDLINE, EMBASE, and the Cochrane CENTRAL were searched to identify randomized trials and prospective cohort studies reporting recurrent VTE among patients with a first unprovoked VTE who were to receive anticoagulation for a minimum of six additional months after completing ≥3 months of initial treatment. Unpublished data on number of recurrent VTE and person-years, obtained from authors of included studies, were used to calculate study-level incidence rate, and random-effects meta-analysis was used to pool results. RESULTS Twenty-six studies and 15 603 patients were included in the analysis. During 11 631 person-years of follow-up, the incidence of recurrent VTE and fatal pulmonary embolism per 100 person-years was 1.41 (95% CI, 1.03-1.84) and 0.09 (0.04-0.16), with 5-year cumulative incidences of 7.1% (3.0%-13.2%) and 1.2% (0.4%-4.6%), respectively. The incidence of recurrent VTE was 1.08 (95% CI, 0.77-1.44) with direct oral anticoagulants and 1.55 (1.01-2.20) with vitamin K antagonists. The case-fatality rate of recurrent VTE was 4.9% (95% CI, 2.2%-8.7%). CONCLUSIONS In patients with a first unprovoked VTE, the long-term risk of recurrent VTE during extended anticoagulation is low but not negligible. Thus, clinicians and patients should be aware of this risk and take appropriate and timely action in case of suspicion of recurrent VTE. Estimates from this study can be used to advise patients on what to expect while receiving extended anticoagulation, and estimate the net clinical benefit of extended treatment to guide long-term management of unprovoked VTE.
