Evaluation of Smartphone Applications for Cardiopulmonary Resuscitation Training in South Korea

Abstract EN

Objective.

There are many smartphone-based applications (apps) for cardiopulmonary resuscitation (CPR) training.

We investigated the conformity and the learnability/usability of these apps for CPR training and real-life supports.

Methods.

We conducted a mixed-method, sequential explanatory study to assess CPR training apps downloaded on two apps stores in South Korea.

Apps were collected with inclusion criteria as follows, Korean-language instruction, training features, and emergency supports for real-life incidents, and analyzed with two tests; 15 medical experts evaluated the apps’ contents according to current Basic Life Support guidelines in conformity test, and 15 nonmedical individuals examined the apps using System Usability Scale (SUS) in the learnability/usability test.

Results.

Out of 79 selected apps, five apps were included and analyzed.

For conformity (ICC, 0.95, p < 0.001 ), means of all apps were greater than 12 of 20 points, indicating that they were well designed according to current guidelines.

Three of the five apps yielded acceptable level (greater than 68 of 100 points) for learnability/usability.

Conclusion.

All the included apps followed current BLS guidelines and a majority offered acceptable learnability/usability for layperson.

Current and developmental smartphone-based CPR training apps should include accurate CPR information and be easy to use for laypersons that are potential rescuers in real-life incidents.

For Clinical Trials.

This is a clinical trial, registered at the Clinical Research Information Service (CRIS, cris.nih.go.kr), number KCT0001840.
