About this study

Official title: Feasibility and Intelligibility Testing of a Microphone System to Facilitate Patient Communication During Noninvasive Ventilation

Assessing speech intelligibility in a pilot study of patients speaking with a mask microphone while being treated with standard of care non-invasive ventilation. This is a feasibility study to test the microphone in a real world setting.

Read the detailed description

We will conduct a prospective feasibility study to evaluate speech intelligibility of 10 patients (target distribution of gender: 5 males, 5 females) undergoing standard of care, clinically indicated non-invasive ventilation. Patients will be their own control with and without the ReddyPort™ microphone using a crossover design, with the sequence of conditions randomized (half of patients start with microphone turned on, half start with the microphone turned off). The patients in this study will all receive standard of care. No medical decisions for a change in care will result from the speech recordings obtained during this feasibility study. The speech recordings will be analyzed off-site using a pool of blinded volunteers. The microphone on and off test conditions will not be used to change outcome of the clinical course of care.

What is being measured

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

  1. Rating of speech intelligibility

    The 1-5 likert scale developed by Yorkston et al will be used to evaluate speech intelligibility of the device (Yorkston, Kathryn M., David R. Beukelman, and Charles Traynor. Assessment of intelligibility of dysarthric speech. Austin, TX: Pro-ed, 1984.Powell TW. A comparison of English reading passages for elicitation of speech samples from clinical populations. Clin Linguist Phon. 2006;20(2-3):91-7)

    Measured: Intelligibility will be rated offline by blinded listeners who hear the recording 1-12 weeks after speaking tasks are complete.

Secondary outcomes (3)
  1. Rating of microphone likability

    Subjects will be asked how well they liked using the microphone on a Likert-type scale of 1-5, from extremely unlikable (1) to extremely likable (5)

    Measured: Immediately after speaking tasks are complete

  2. Rating of speech comprehensibility

    Subjects will be asked how well they could understand the speech on a Likert-type scale of 1-5, from not at all understandable (1) to fully understandable (5)

    Measured: Immediately after speaking tasks are complete

  3. Rating of how natural the speech sound quality is

    Subjects will be asked how natural the speech sound quality is on a Likert-type scale of 1-5, from not natural (1) to completely natural (5)

    Measured: Immediately after speaking tasks are complete

Questions about this trial

What is this clinical trial studying?

A study testing Noninvasive Ventilation Mask Microphone in people with Noninvasive Ventilation and Speech Intelligibility, run by University of Utah 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 9 inclusion and 4 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 1 Aug 2022. 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?

Rating of speech intelligibility (time frame: Intelligibility will be rated offline by blinded listeners who hear the recording 1-12 weeks after speaking tasks are complete.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04912544, which also lists 1 linked publication.

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 1 Aug 2022.
