Medical Dispatchers' Perception of Visual Information in Real Out-of-hospital Cardiac Arrest

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.

Study Overview

• Status: Completed
• Conditions: Out-Of-Hospital Cardiac Arrest
• Intervention / Treatment: Other: CCTV footage to the medical dispatcher in OHCA

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.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	One hour interview with earch of the emergency medical dispathers
