Summary

This is a pragmatic, single center, feasibility pilot cluster randomized trial with embedded individual randomization to evaluate implementation strategies to increase the use of evidence-based practices to reduce upper gastrointestinal bleeding risk in patients using combination antithrombotic therapy (including warfarin) and that are managed by the Michigan Medicine anticoagulation monitoring service.

Detailed description

In February 2022, the IRB approved adding a small additional substudy for the collection of exploratory qualitative outcomes only, involving up to 8 primary care physicians. As no data for the primary and secondary outcome measures was collected for this substudy, and all data collection for this group was related to exploratory outcome measures and collected through qualitative interviews with clinicians, no inclusion exclusion criteria specific to the participants in this substudy are listed, nor does the data collection from them show in the study completion date or results data. However, these physicians (n=8) and their patients (n=9) are counted in the actual enrollment total since they were randomized to intervention arms and received study interventions.

Conditions

• Upper Gastrointestinal Bleeding

Interventions

Type	Name	Description
BEHAVIORAL	Clinician notification	An anticoagulation clinic nurse sends a templated letter to the patient's clinician and identifies the patient as high risk for upper GI bleeding, summarizes options for medication optimization (e.g., discontinuation of antiplatelet therapy or initiation of a proton pump inhibitor for gastroprotection), provides a link to guidance on evidence-based use of antiplatelet therapy, and asks that the clinician manage any medication changes. In this arm, patients receive no additional interventions beyond that provided during treatment as usual.
BEHAVIORAL	Clinician Notification with Nurse Facilitation	An anticoagulation clinic nurse sends an individualized letter to the patient's clinician which identifies the patient as high risk for upper GI bleeding and summarizes options for medication optimization (e.g., discontinuation of antiplatelet therapy or initiation of a proton pump inhibitor for gastroprotection), but in addition includes a summary of the patient's history of atherosclerotic cardiovascular disease and a concise guidance summary on appropriate use of antiplatelet therapy for relevant indications. The anticoagulation nurse will assist with order entry for any new medications and also provide education on medication changes to the patient upon request by the clinician. In this arm, patients receive no additional interventions beyond that provided during treatment as usual.
BEHAVIORAL	Clinician Notification / Patient Activation	An anticoagulation clinic nurse sends a templated letter to the patient's clinician and identifies the patient as high risk for upper GI bleeding, summarizes options for medication optimization (e.g., discontinuation of antiplatelet therapy or initiation of a proton pump inhibitor for gastroprotection), provides a link to guidance on evidence-based use of antiplatelet therapy, and asks that the clinician manage any medication changes. Patient Activation: An anticoagulation clinic nurse sends the patient an 8-page written guide, either through the patient portal or by mail. The guide provides education on upper GI bleeding risk and encourages patients to talk with their clinician about medication changes to reduce their bleeding risk.
