What is the purpose of this trial?

This trial tests whether a shorter, simpler consent form improves understanding of a clinical study compared to the usual detailed form. It is part of a larger trial focused on treating Staphylococcus aureus bloodstream infections, which are serious bacterial infections. Participants will receive either the Simplified Layered Consent Form or the Full-length Consent Form to determine which makes the consent process easier and more satisfying. Ideal candidates for this trial are those admitted to a participating hospital, with a blood test confirming a Staphylococcus aureus infection, and who can read and speak either English or French. As an unphased study, this trial offers an opportunity to enhance the consent process for future patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are on a systemic antibacterial agent that cannot be stopped, you may not be eligible to participate.

What prior data suggests that these consent forms are safe for use in clinical trials?

This trial aims to improve how clinical trials are explained to participants by comparing a simplified consent form to a traditional one.

Research has shown that people prefer the simplified consent form. One study found that participants appreciated having choices about how much information to read before deciding to join a trial. This suggests that the simplified form is safe and easy to use.

No safety concerns exist because this trial does not involve testing a drug or treatment. It only tests how information is shared, so participants are not at risk from the consent forms themselves. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it's testing a new way to simplify the consent process for clinical trials. Unlike the traditional full-length consent forms that are often lengthy and complex, the simplified layered consent form is concise, using easy-to-understand language in a four-page document. This approach aims to make it easier for participants to comprehend the trial's details and make informed decisions. By streamlining the consent process, researchers hope to improve participant understanding and engagement, potentially enhancing the overall efficiency and ethical standards of clinical trials.

What evidence suggests that the simplified layered consent form is effective for improving recruitment and understanding in clinical trials?

This trial will compare the effectiveness of a Simplified Layered Consent Form with a Full-Length Consent Form. Research has shown that simpler consent forms can improve understanding and satisfaction during the consent process. Studies have found that allowing individuals to choose how much information to read makes them feel more comfortable and informed. This approach might also increase participation in clinical trials. By using clear and simple language, the form helps people understand the trial's purpose. Early findings suggest this method respects individuals' preferences for detail before making a decision. ^{1 2 3 4 6}

Are You a Good Fit for This Trial?

This trial is for adults with a Staphylococcus aureus blood infection, who speak English or French well enough to understand the consent process. They must be in a participating hospital and not have multiple bacteria in their blood, nor be on certain antibiotics they can't stop. Patients already enrolled in SNAP or treated for S. aureus recently cannot join.

Inclusion Criteria

Self-reported proficiency in English or French adequate to be able to participate in consent process carried out solely in English or French (as the supplementary consent materials required in the simplified consent process are currently only available in these two languages)

Admitted to participating hospital of SIMPLY-SNAP

S. aureus complex grown from ≥1 blood culture

Exclusion Criteria

My blood test shows infection with more than one type of bacteria.

I am on a long-term antibacterial treatment that cannot be stopped.

Time of anticipated platform entry is greater than 72 hours post collection of the index blood culture

What Are the Treatments Tested in This Trial?

Interventions

• Full-length Consent Form
• Simplified Layered Consent Form

Trial Overview

The SIMPLY-SNAP trial tests if a simplified layered consent form improves recruitment rates, understanding of the study, and satisfaction compared to a full-length form during informed consent for treating Staph infections. Participants will receive either the detailed or simplified form randomly.

How Is the Trial Designed?

Group I: Simplified layered consent process Experimental Treatment 1 Intervention

For participants randomized to the SIMPLY-SNAP experimental group, a simplified layered consent process will be used to explain information for the SNAP trial. The research staff member obtaining consent will provide a standardized explanation, providing summarized information in simple English or French contained in a 4-page concise participant information sheet. Throughout the consent process, the research staff member will answer any questions that the participant has, to reflect routine consent discussion practice.

Group II: Full-length consent form Active Control 1 Intervention

For participants randomized to the control group, the existing consent process will be used including going through the currently approved full-length informed consent form. The research staff member will provide an explanation using the full-length informed consent form as per standard clinical trial procedures. Similarly, throughout the consent process, the research staff member will answer any participant questions as per normal procedures.

Published Research Related to This Trial

Consumers, including survivors of Staphylococcus aureus bloodstream infection and their carers, support a layered approach to participant information sheets/consent forms (PICFs), which allows them to choose how much information to read before consenting to a trial.

The study highlighted the importance of prioritizing participants' information needs and providing clear details about the benefits of a trial, suggesting that a concise 3-page PICF could be effective for decision-making if additional information is readily accessible.
