LEAVE Safe With DOACs

February 15, 2024 updated by: Alok Kapoor, University of Massachusetts, Worcester

Leveraging Evidence-based Practices for Ambulatory VTE and Other Patients to be Safe With Direct Oral Anticoagulants: LEAVE Safe With DOACs

Given the risks associated with direct oral anticoagulants (DOACs) and the lack of defined pathways for patients prescribed this class of medications, the study intervention has the potential for an enormous impact in preventing medication errors and improving the quality of care transition, patient knowledge, and adherence with DOAC therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients first treated with direct oral anticoagulants (DOACs) in an ambulatory setting are at an elevated risk for adverse drug events (ADEs) or potential ADEs from medication errors. An intervention that integrates clinical pharmacists, a pharmacy technician, and follows a checklist published by experts at the Anticoagulation Forum can prevent adverse outcomes. The Investigators propose research on the effectiveness, implementation, and dissemination for a care transition intervention that follows the checklist which includes evaluation for appropriateness of DOAC use, assistance with drug procurement, telephone access to an anticoagulation expert, and other best practice recommendations.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age ≥ 18
  • New prescription of DOAC within 4 days of consent OR continued DOAC use for a patient with new episode of worsening thromboembolic or bleeding event within 4 days of consent or discharged from the hospital with DOAC prescription within 4 days of consent
  • Fluency in English, Portuguese, or Spanish

Exclusion Criteria:

  • Currently hospitalized with inpatient status (as opposed to observation status)
  • Age < 18

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control
Experimental: Clinical Pharmacist Intervention
Other: Clinical Pharmacist Intervention
After randomization, the pharmacist calls patients to assess drug choice and dose. Staff distribute manufacturer coupons and help patients apply for medication payment assistance. Pharmacist discusses DOAC alternatives with prescribe and provides DOAC education by discussing potential adverse effects, medication interactions, alarm symptoms, and lab work. Staff mail educational materials. Pharmacist documents concerns in the electronic health record and messages prescriber about missing lab work. Patients share medication-related concerns. Patients are provided with a phone number for non-education calls to discuss their medications from 6 AM - 10 PM on any day. The pharmacist offers dose de-escalation instructions based on the DOAC prescription. The pharmacist advises the continuity provider on DOAC duration and monitoring. For follow-up/perioperative support, the pharmacist reviews and recommends lab monitoring and gives DOAC interruption/resumption recommendations.

  • Clinical Pharmacist Intervention Based on Checklist Endorsed by the AC Forum

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Direct Oral Anticoagulant (DOAC)-Related Clinically Important Medication Errors
Time Frame: 90 Days Post Enrollment
The number of preventable, ameliorable and potential Adverse Drug Events (ADEs) that physician reviewers attribute to Direct Oral Anticoagulant (DOAC) medication. Each DOAC related clinically important medication error is counted as a separate event, enabling patients to have multiple events consistent with the literature.
90 Days Post Enrollment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient Knowledge regarding Anticoagulation and Venus Thromboembolism (VTE) using the Anticoagulation and Venus Thromboembolism (VTE) knowledge questionnaire
Time Frame: 90 Days Post Enrollment
Patient knowledge regarding Anticoagulation and Venus Thromboembolism (VTE) will be evaluated using a modified version of a 22-item instrument previously developed and tested by the institution. This instrument assesses patients' knowledge of warning signs of bleeding and new VTE, interactions with other medications, and complications of VTE. A low score indicate a low level of knowledge and a high score indicates a high level of knowledge regarding anticoagulation and VTE.
90 Days Post Enrollment
Number of missed or extra doses to assess medication adherence
Time Frame: 90 Days Post Enrollment
Patients are asked to to count out the number of remaining pills from the last filled prescription and provide the fill date, number of pills dispensed, the schedule prescribed (either once or twice a day depending on DOAC), and skipped doses for deliberate interruption to determine medication adherence with the number of missed or extra doses.
90 Days Post Enrollment
Medication Possession Ratio (MPR) to assess medication adherence
Time Frame: 90 Days Post Enrollment
Medication adherence is measured with Medication Possession Ratio (MPR) which is the ratio between the time a patient had medication on hand, the time that a patient is eligible to have a medication on hand, and the time that a patient is covered by the medication. The MPR ratio will be calculated by using available pharmacy data.
90 Days Post Enrollment
Proportion of days covered (PDC) to assess medication adherence
Time Frame: 90 Days Post Enrollment
Proportion of Days Covered (PDC) is the ratio between the time that a patient has a medication on hand, the time that a patient is eligible to have a medication on hand, and the time that a patient is covered by the medication. Medication adherence will be evaluated using the mean PDC using available pharmacy data.
90 Days Post Enrollment
