About this study
Official title: Medical Dispatchers' Perception of Visual Information in Real Out-of-hospital Cardiac Arrest: A Qualitative Interview Study
Dispatcher-assisted cardiopulmonary resuscitation is a complex, nonvisual procedure that is challenging for the dispatcher. The aim was to explore the medical dispatchers' perception of bystanders' responses and dispatchers' reflections about the added value of visual information in out-of-hospital cardiac arrests (OHCA) situations.
Read the detailed description
Ten individual interviews with medical dispatchers who had previously handled an emergency call concerning OHCA captured on closed-circuit television (CCTV) were conducted. First, the medical dispatcher listened to the emergency call and described their perception of the scenario. Afterward, the CCTV recording was shown to the dispatcher, who was then interviewed. The interviews were videotaped, and the audio files were transcribed verbatim. Thematic content analysis was conducted.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CCTV footage to the medical dispatcher in OHCAOther
The medical dispatchers' perception of bystanders' responses and dispatchers' reflections about the added value of visual information in out-of-hospital cardiac arrests (OHCA) situations.
What is being measured
The primary outcome is the main question the study is designed to answer.
The added value of visual information to the medical dispatcher in out-of-hospital cardiac arrests (OHCA) situations.
We applied a qualitative research methodology using thematic analysis with an explorative and inductive approach. The first author followed Braun and Clarke's six-step analytical approach, which has the following steps: familiarising with data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report. Codes and themes were organised using Nvivo10 software (QSR International Pty Ltd, Australia). Analysis continued until saturation; that is, when information became redundant.
Measured: One hour interview with earch of the emergency medical dispathers

Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 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 26 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
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?
The added value of visual information to the medical dispatcher in out-of-hospital cardiac arrests (OHCA) situations. (time frame: One hour interview with earch of the emergency medical dispathers). 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 26 Oct 2018.
