Better adherence to the guidelines during cardiopulmonary resuscitation through the provision of audio-prompts

Objective: Quality assurance to optimize clinical resuscitation performance is important. The aims of the present study were to identify the deficiencies in the clinical practice of resuscitation by motion analysis of video-recorded cardiopulmonary resuscitation (CPR), and to evaluate the effectiveness of quality improvement strategies based on audio-prompt methods. Materials and methods: A two-stage prospective trial was conducted. The first stage (observation group) was designed to identify any major clinical nonconformity to current resuscitation guidelines by videotaped CPR sessions. The second stage (intervention group) was designed to evaluate the effectiveness of audio prompts in ameliorating the problems identified at the first stage. The demographic data of patients and CPR variables between the two groups were analysed. Results: A total of 30 resuscitation attempts were recorded during study period: 17 patients were in the observation group and 13 patients in the intervention group. Inadequate number of chest compressions per minute, lack of re-oxygenation during prolonged intubation attempts and unnecessary hands-off periods were identified as the three most important deficiencies in CPR practice. Compared to the observation group, the intervention group showed a significant improvement in the hands-off period per minute during CPR (12.7 ± 5.3 s versus16.9 ± 7.9 s, P < 0.05), the total hands-off time during CPR (164 ± 94 s versus 273 ± 153 s, P < 0.05), the proportion of intubation attempts taking under 20 s (56.3% versus 10%, P < 0.05). Conclusions: Audio-prompts can improve the adherence to current CPR guidelines in the clinical setting significantly. The quality improvement measures described in this study are helpful in translating CPR knowledge into clinical practice.
