About this study

Official title: Impact of a Smartphone App Reminder on Adherence Aspirin Prescribed as Anti-Thrombotic Therapy

The purpose of this study is to explore the impact of using a smartphone app reminder on medication adherence twice daily in adults prescribed 81 milligrams of aspirin for 35 days as anti-thrombotic therapy after knee or hip arthroplasty.

This study will randomly assign participants to get usual postoperative care which is teaching with verbal instructions and printed information about taking the aspirin at the time of discharge, or to have an app on your smartphone with preset reminders in addition to usual postoperative discharge teaching after surgery.

Read the detailed description

The purpose of this study is to evaluate the impact of using a smartphone application (app) reminder on medication adherence twice daily in 200 adults prescribed 81 milligrams of aspirin (ASA) for 35 days as anti-thrombotic therapy after knee or hip arthroplasty. The aim is to determine if an app downloaded on a smartphone that reminds patients twice a day to take their ASA as prescribed will improve ASA adherence and clinical outcomes for patients after total knee and total hip joint arthroplasty compared to those in the usual care.

This is a two group, randomized control study with random assignment into the control group for usual care or the intervention group to receive a medication reminder app for their smart phone (daily for 35 days) plus usual care. Participants will receive a baseline interview for demographic and other data and 36 day follow-up assessment, both conducted in person.

What participants receive

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

  • Standard EducationBehavioural

    Participants will receive the usual verbal education and printed information provided to patients about the importance of taking aspirin to prevent thromboembolic events after orthopedic surgery, medication dosage and scheduling.

  • Medication Reminder AppBehavioural

    Participants will use a medication reminder app that is set in collaboration with the participants for times that fit into their daily lifestyle. The app will alert participants when it is time (selected by the participant) to take their medication.

What is being measured

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

  1. Proportion of Pills Taken

    The proportion of pills taken is defined as the percentage of pills taken by study participants.

    Measured: Post- Operative Visit (Day 36)

Secondary outcomes (9)
  1. AIDS Clinical Trials Group (ACTG) Adherence Questionnaire Score

    The ACTG Adherence Questionnaire consists of 19 items measuring different aspects of efficacy (or confidence) in the management of one's medication. Each item is rated from 0 ("I cannot do at all") to 10 ("Sure I can do"), with total scores found by summing responses to individual items and dividing by 19. Higher scores correspond to higher levels of medication self-efficacy.

    Measured: Post- Operative Visit (Day 36)

  2. Aspirin (ASA) Self-Efficacy Scale Score

    The ASA Self-Efficacy Scale consists of 19 items measuring different aspects of efficacy (or confidence) in the management of one's medication. Each item is rated from 0 ("I cannot do at all") to 10 ("Sure I can do"), with total scores found by summing responses to individual items and dividing by 19. Higher scores correspond to higher levels of medication self-efficacy.

    Measured: Post- Operative Visit (Day 36)

  3. Number of Thromboembolic Events

    Clinical outcomes will be assessed at follow-up by self-report questions to ascertain if any thromboembolic events occurred.

    Measured: Post- Operative Visit (Day 36)

  4. Aspirin (ASA) General Adherence Scale Score

    The ASA General Adherence Scale measures the ease and ability to adhere to the ASA regimen as prescribed. It is scored by summing responses to the individual items and creating a total score. Higher scores indicate better self-reported adherence.

    Measured: Post- Operative Visit (Day 36)

  5. Unified Theory of Acceptance and Use of Technology (UTAUT2) Survey Score

    The UTAUT2 measures antecedents (performance expectancy, effort expectancy, hedonic motivation) and behavioral intent to use mobile apps. Items are scored using a 7-point Likert scale, from 1 (strongly disagree) to 7 (strongly agree). Survey totals range between 14 and 112. Higher scores are indicative of greater acceptance and intent to adopt the target technology.

    Measured: Baseline (Pre-Intervention)

  6. Performance Expectancy Subscale Score

    The Performance Expectancy Subscale measures the perceived benefits of mobile app technology to the consumer. Scores range from 4 to 28, with higher totals indicating better perceptions of technology-related benefits.

    Measured: Baseline (Pre-Intervention)

  7. Effort Expectancy Subscale Score

    The Effort Expectancy Subscale measures the ease with which the consumer can learn and operate an app. Scores range from 4 to 28, with higher totals indicating greater beliefs that the technology is easy and accessible.

    Measured: Baseline (Pre-Intervention)

  8. Hedonic Motivation Subscale Score

    The Hedonic Motivation subscale measures the enjoyment, the consumer experiences from using an app. Respondents answer each item on a 7-point Likert-type scale ranging from 1 (Absolutely True) to 7 (Absolutely Untrue). Scoring is kept continuous with higher scores indicating greater enjoyment.

    Measured: Baseline (Pre-Intervention)

  9. Behavioral Intent Subscale Score

    The Behavioral Intent Subscale measures the decision to use a mobile app. Scores range from 3 to 21, with higher totals indicating a greater intent to use or adopt an app.

    Measured: Baseline (Pre-Intervention)

Questions about this trial

What is this clinical trial studying?

A study testing Standard Education and Medication Reminder App in people with Thromboembolic Event, run by Emory University 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 4 inclusion and 2 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 23 Oct 2019. 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?

Proportion of Pills Taken (time frame: Post- Operative Visit (Day 36)). 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 23 Oct 2019.
