Main objective

Scope: Therapy, Dose response, Efficacy

The primary aim of this study is to evaluate the efficacy of a Single Measurement and adjustment strategy based on DOAC levels in the frail older population on the incidence of complications, in particular thromboembolic events or bleedings as composite outcome.

Secondary objectives 1

  1. Secondary objectives are to evaluate (1) the prevalence of deviant DOAC levels in the frail older population, (2) which determinants are associated with a deviant DOAC level, (3) differences in quality of life between both groups, (4) the feasibility/acceptability of the Single Measurement and adjustment strategy via a qualitative study, (5) cost-effectiveness, and (6) mortality.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 1

  1. In order to be eligible to participate in this study, a subject must meet all of the following criteria: (a) aged > 70 years; (b) using a DOAC (preferably among new users, defined as participants initiating treatment with a DOAC), (c) CFS > 3, (d) able to attend to the outpatient clinic (only applicable to community dwelling patients), and (e) able to provide informed consent.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Our primary end point is the composite outcome of thromboembolic events or bleedings. Bleeding is defined as major bleeding or a clinically relevant non-major (CRNM) bleeding, based on the definition of the International Society on Thrombosis and Haemostasis (ISTH). Thromboembolic events include ischemic stroke, transient ischemic accident (TIA) en peripheral thromboembolism.

Secondary endpoints 1

  1. Our secondary end points are (1) the prevalence of deviant DOAC levels in the frail older population, (2) determinants are associated with a deviant DOAC level, (3) differences in quality of life between both groups, (4) the feasibility/acceptability of the Single Measurement and adjustment strategy via a qualitative study, (5) cost-effectiveness of the intervention, and (6) mortality.
