About this study

The purpose of this study is to demonstrate the feasibility and effectiveness of anticoagulation self-monitoring coupled with an educational intervention in a minority underserved population.

Read the detailed description

Despite favorable results and enhanced patient convenience, the adoption of patient self-monitoring for anticoagulation therapy has been limited primarily to non-minority and higher socioeconomic status individuals. While effectiveness has been studied, the factors influencing the adoption of self-monitoring of anticoagulation in minorities with the most barriers to accessing quality care in specialized clinics, are not known.

Hypothesis: Patient centered education and training intervention for minority patients will result in effective adoption of self-monitoring of anticoagulation therapy, resulting in anticoagulation control of comparable quality to that seen in specialized anticoagulation clinic-based monitoring.

The research objective of this proposal will be accomplished through 3 specific aims:

  1. Identify patient and provider factors that influence adoption of anticoagulation self-monitoring in a minority population.
  2. Adapt and refine an education intervention that both addresses identified barriers and emphasizes identified positive influences to anticoagulation self-monitoring.
  3. Demonstrate the feasibility and effectiveness of anticoagulation self-monitoring coupled with an educational intervention in a minority population.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Patient Self-Monitoring vs Anticoagulation ClinicOther

    Patient Self-Monitoring (intervention): entails 3 education sessions of 90-120 minutes each (week 0, week 2, week 4): 2 provided on site in clinic and 1 in the patient's home, during which, self-testing competency and barriers and facilitators to self-monitoring will be evaluated. Subjects will follow with weekly (or sooner, if clinically indicated) in-home self-monitoring and follow-up weekly phone calls over 6 months by clinical pharmacists to guide warfarin dosing and reinforce key educational messages.

    Anticoagulation Clinic (control): subjects will have their INR tested in clinic monthly (or more frequently if clinically indicated) via the Coaguchek® point-of-care device (which is the standard of care in the Anticoagulation Clinic) and receive dosing instructions and standardized education related to warfarin by a clinical pharmacist who provides care in the Anticoagulation Clinic.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent time in therapeutic range (TTR)

    TTR will be calculated for each patient using the linear interpolation method. This method has been associated with clinical outcomes such as risk for thromboembolic events, and thus was selected over other methods of expressing the TTR such as fraction of International Normalized Ratio (INR) in range and cross-section of files

    Measured: Month 1, Month 2, Month 4, Month 7

Secondary outcomes (5)
  1. Treatment Related Quality of Life

    It will be evaluated using a 25 item validated questionnaire that assesses limitations, hassles, and positive impact with a Cronbach alpha for each of 0.87, 0.88 and 0.78 respectively

    Measured: Baseline, Month 1, Month 7

  2. Anticoagulation Related Knowledge

    It will be measured with an instrument containing 29 items at different levels of difficulty to allow differences in patient knowledge to be evaluated and has a person reliability coefficient of 0.75.

    Measured: Baseline, Month 1, Month 7

  3. Adherence with Monitoring

    It is defined as the INR test completed within 24 hours of scheduled time and measured via the Coaguchek® device in home or clinic.

    Measured: Month 1, Month 2, Month 4, Month 7

  4. Self-Testing Competency (Intervention group only)

    It is defined as the ability to attain an INR reading and provider observed technique.

    Measured: Baseline to 7 months

  5. Self-Testing Accuracy (Intervention group only)

    It is defined as the concordance of self-reported and device-stored INR measurements.

    Measured: Baseline to 7 months

Questions about this trial

What is this clinical trial studying?

A study testing Patient Self-Monitoring vs Anticoagulation Clinic in people with Thromboembolism and Blood Coagulation Disorders, run by University of Illinois Chicago at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent time in therapeutic range (TTR) (time frame: Month 1, Month 2, Month 4, Month 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2020.
