Use of a Patient-Centered Electronic App to Increase ED Patient's Knowledge on HCV to Improve the HCV Care Continuum
What this study is about
The investigators will conduct a randomly assigned controlled clinical trial study in an urban emergency department in Baltimore to determine the impact of an educational app which is based on Leventhal's Common-Sense Model of Illness Representations framework, on HCV-infected ED patient's hepatitis C virus (HCV) health belief and knowledge as well as the downstream outcomes of the HCV Continuum of Care (linkage to care rate, initiation of HCV antiviral treatment, and sustained virologic response). First, the investigators will develop a blueprinted prototype personalized HCV educational app which will (1) provide individualized liver fibrosis staging information, (2) pre-test HCV knowledge, perception of barriers to HCV care, and motivation to receive HCV care survey, (3) provide personalized HCV knowledge, facilitators and supporting information for HCV care via video clips and information sheets based on the pre-test results, and (4) provide post-test knowledge, perception, and motivation to receive HCV care. Second, the investigators will conduct a series of focus group discussion sessions to fine-tune the HCV educational app. Third, the investigators will enroll ED patients who have anti-HCV (newly diagnosed or previously diagnosed) but without HCV RNA testing information for a pilot randomly assigned controlled clinical trial of the personalized HCV educational app.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
