Brief compression-only cardiopulmonary resuscitation and automated external defibrillator course for secondary school students: a multischool feasibility study.

ABSTRACT: OBJECTIVES:This study assessed the feasibility and preliminary efficacy of a 2-hour compression-only cardiopulmonary resuscitation and automated external defibrillator (CO-CPRAED) course in secondary school students. DESIGN:Prospective pre-post feasibility study. SETTING AND PARTICIPANTS:128 students (12-15 years old) without prior basic life support (BLS) training at four secondary schools in Hong Kong. All students were followed up at 3 months after training. INTERVENTIONS:Emergency medicine-trained nurse and physicians taught the 2-hour CO-CPRAED course using the American Heart Association 'CPR in School Training Kit' programme. Students were trained in groups up to 40 students/session, with an instructor to student ratio not exceeding 1:10. To practise hands-on compressions, the manikin to student ratio was 1:1. For a simulated cardiac arrest, the manikin and AED to student ratio was 1:10. PRIMARY AND SECONDARY OUTCOMES:CPR and AED knowledge, attitude statements towards bystander CPR and AED, quality of BLS performance skills during training and at 3 months. RESULTS:Some students (46%) knew how deep to push on an adult chest when doing CO-CPR before training. The course was associated with an increase in knowledge score (pretraining 55%, post-training 93%; adjusted mean difference (MD) 38%, 95% CI 33% to 43%; p<0.001). Most students (68%) thought that CPR education in senior secondary school was essential before training. The students had a very positive attitude towards CPR; no change in the mean (SD) attitude score out of 30 over time (pretraining 27.2 (2.5), post-training 27.6 (2.7); adjusted MD 0.5, 95% CI -0.1 to 1.0; p=0.132). Most students were competent in performing BLS immediately after training (77%) and at 3 months (83%) (adjusted MD 6%, 95% CI -4% to 15%; p=0.268). CONCLUSIONS:The results demonstrate the feasibility of scaling up the number of secondary schools trained in a brief CO-CPRAED course within the local school curriculum.

Project description:New chest compression detection technology allows for the recording and graphical depiction of clinical cardiopulmonary resuscitation (CPR) chest compressions. The authors sought to determine the inter-rater reliability of chest compression pattern classifications by human raters. Agreement with automated chest compression classification was also evaluated by computer analysis.This was an analysis of chest compression patterns from cardiac arrest patients enrolled in the ongoing Resuscitation Outcomes Consortium (ROC) Continuous Chest Compressions Trial. Thirty CPR process files from patients in the trial were selected. Using written guidelines, research coordinators from each of eight participating ROC sites classified each chest compression pattern as 30:2 chest compressions, continuous chest compressions (CCC), or indeterminate. A computer algorithm for automated chest compression classification was also developed for each case. Inter-rater agreement between manual classifications was tested using Fleiss's kappa. The criterion standard was defined as the classification assigned by the majority of manual raters. Agreement between the automated classification and the criterion standard manual classifications was also tested.The majority of the eight raters classified 12 chest compression patterns as 30:2, 12 as CCC, and six as indeterminate. Inter-rater agreement between manual classifications of chest compression patterns was ? = 0.62 (95% confidence interval [CI] = 0.49 to 0.74). The automated computer algorithm classified chest compression patterns as 30:2 (n = 15), CCC (n = 12), and indeterminate (n = 3). Agreement between automated and criterion standard manual classifications was ? = 0.84 (95% CI = 0.59 to 0.95).In this study, good inter-rater agreement in the manual classification of CPR chest compression patterns was observed. Automated classification showed strong agreement with human ratings. These observations support the consistency of manual CPR pattern classification as well as the use of automated approaches to chest compression pattern analysis.
