Abstract

Background

Bridging anticoagulation is commonly prescribed to patients with atrial fibrillation during initiation and interruption of warfarin. Guidelines recommend bridging patients at high risk of stroke, while a recent randomized trial demonstrated overall harm in a population at comparatively low risk of ischemic stroke. Theory suggests that patients at high risk of stroke and low risk of hemorrhage may benefit from bridging, but data informing patient selection are scant.

Objective

To estimate the utility and cost-effectiveness of bridging anticoagulation among patients with nonvalvular atrial fibrillation, stratified by thromboembolic and hemorrhagic risk

Design

Cost-effectiveness analysis with lifelong time horizon, from the perspective of a third-party payer

Main Measures

Quality-adjusted life years (QALYs) per bridged patient; US dollars per QALY gained

Key Results

Unselected patients with nonvalvular atrial fibrillation may be harmed by bridging anticoagulation. Hospital admission for bridging is almost never cost-effective, and generally harmful. Among patients carefully selected by both thromboembolic and hemorrhagic risks, outpatient bridging can be beneficial and cost-effective. Results were sensitive to how effectively heparin products reduce stroke risk.

Conclusions

Outpatient bridging anticoagulation can be beneficial and cost-effective for a subset of patients with nonvalvular atrial fibrillation during interruption or initiation of warfarin. Admission for bridging should be avoided.

Echinokokkose medikamentös behandeln oder operieren?

06.05.2024 DCK 2024 Kongressbericht

Die Therapie von Echinokokkosen sollte immer in spezialisierten Zentren erfolgen. Eine symptomlose Echinokokkose kann – egal ob von Hunde- oder Fuchsbandwurm ausgelöst – konservativ erfolgen. Wenn eine Op. nötig ist, kann es sinnvoll sein, vorher Zysten zu leeren und zu desinfizieren.

Aquatherapie bei Fibromyalgie wirksamer als Trockenübungen

03.05.2024 Fibromyalgiesyndrom Nachrichten

Bewegungs-, Dehnungs- und Entspannungsübungen im Wasser lindern die Beschwerden von Patientinnen mit Fibromyalgie besser als das Üben auf trockenem Land. Das geht aus einer spanisch-brasilianischen Vergleichsstudie hervor.

Wo hapert es noch bei der Umsetzung der POMGAT-Leitlinie?

03.05.2024 DCK 2024 Kongressbericht

Seit November 2023 gibt es evidenzbasierte Empfehlungen zum perioperativen Management bei gastrointestinalen Tumoren (POMGAT) auf S3-Niveau. Vieles wird schon entsprechend der Empfehlungen durchgeführt. Wo es im Alltag noch hapert, zeigt eine Umfrage in einem Klinikverbund.

Das Risiko für Vorhofflimmern in der Bevölkerung steigt

02.05.2024 Vorhofflimmern Nachrichten

Das Risiko, im Lauf des Lebens an Vorhofflimmern zu erkranken, ist in den vergangenen 20 Jahren gestiegen: Laut dänischen Zahlen wird es drei von zehn Personen treffen. Das hat Folgen weit über die Schlaganfallgefährdung hinaus.
