Low-Dose, High-Frequency CPR Training Improves Skill Retention of In-Hospital Pediatric Providers

Background: Hyper/over-ventilation (HOV) negatively effects cerebral blood and coronary artery flow during cardiac arrest. The resuscitation quality improvement (RQI) model of low-dose, high-frequency (LDHF) CPR training has been shown to improve CPR skills. Due to the deleterious impact of HOV on survival, our study seeks to determine if the RQI model improves ventilation skills for EMS personnel. We test the hypothesis that the RQI training results in improved and sustained ventilation performance. Methods: In 2014, our department transitioned from traditional BLS/ACLS training to the RQI model. Performance metrics are captured automatically for each rescuer on a quarterly basis using high-fidelity mannequins. Inclusion: All data from adult RQI attempts by EMS personnel from 2015-2019. Exclusion: attempts by non-EMS personnel. The 1 outcome measure is the overall mean (95% CI) ventilation score (composite measure, range 0-100, derived from average volume/rate and % with correct volume). The 2nd outcome measure is the proportion (95%CI) of rescuers with ventilation scores >90%. Data were extracted from RQI and analyzed with Prism statistical software. Comparisons for the 1 outcome was performed using one-way ANOVA and we report mean and 95% CI and proportions and 95% CI as appropriate. Results: During the study period, 740 personnel completed 1,490 ventilation activities in the baseline period and 5,077 in the subsequent years. The mean (95% CI) composite ventilation scores for the baseline was 84.10 (83.09,85.10) vs 2016 = 83.13 (82.17,84.09), 2017=88.79 (87.91,89.66), 2018=90.36 (89.45, 91.27), 2019= 88.59 (87.37, 89.81) for years 2016-2019; F= 41.36, R2=0.024, p value <0.0001. 10outcome: In the baseline RQI year, there were 55.3 % (95%CI= 52.8,57.8) participants with composite ventilation scores >/=90% vs. 2016= 53.5% (51.2,55.8), 2017=65.2%(62.6,68.6), 2018= 71.7%(69.1,74.3) and 2019=69.3%(66.1,72.2) in subsequent years. Limitations: Individual performance not reported, single agency. Conclusions: LDHF CPR training improves proper, and exceptional, ventilation performance in fire-based EMS personnel. Our results may be useful for other EMS agencies who are considering transitioning to LDHF training such as the RQI system.

Purpose The purpose of this paper is to investigate the effects of the intervention of low-dose, high-frequency cardiopulmonary resuscitation (CPR) training with feedback for firefighters for one month. Design/methodology/approach The study had a quantitative approach. Data were collected through an intervention by means of simulation. The data collection consisted of a pre- and post-assessment of 38 firefighter’s CPR performance. Findings There was a statistically significant improvement from pre- to post-assessment regarding participants’ compression rates. Compression depth increased statistically significantly to average 2 mm too deep in the group. Recoil decreased in the group with an average of 1 mm for the better. There was a statistically significant improvement in participants’ ventilation volume from pre- to post-assessment. Originality/value Prehospital staff such as firefighters, police, and ambulance perform CPR under less than optimal circumstances. It is therefore of the utmost importance that these professionals are trained in the best possible way. The result of this study shows that low-dose, high-frequency CPR training with an average of six training sessions per month improves ventilation volume, compression depth, rate, and recoil. This study concludes that objective feedback during training enhances the firefighters’ CPR skills which in turn also could be applied to police and ambulance CPR training.

PurposeThe purpose was to investigate what effect an intervention of low-dose, high-frequency cardiopulmonary resuscitation (CPR) training with feedback for one month would have on professionals' subjective self-assessment skill of CPR.Design/methodology/approachThis study had a quantitative approach. In total, 38 firefighters performed CPR for two minutes on a Resusci Anne QCPR. They then self-assessed their CPR through four multiple-choice questions regarding compression rate, depth, recoil and ventilation volume. After one month of low-dose, high-frequency training with visual feedback, the firefighters once more performed CPR and self-assessed their CPR.FindingsWith one month of low-dose, high-frequency training with visual feedback, the level of self-assessment was 87% (n = 33) correct self-assessment of compression rate, 95% (n = 36) correct self-assessment of compression depth, 68% (n = 26) correct self-assessment of recoil and 87% (n = 33) correct self-assessment of ventilations volume. The result shows a reduced number of firefighters who overestimate their ability to perform CPR.Originality/valueWith low-dose, high-frequency CPR training with visual feedback for a month, the firefighters develop a good ability to self-assess their CPR to be performed within the guidelines. By improving their ability to self-assess their CPR quality, firefighters can self-regulate their compression and ventilation quality.

Cpr Training

Abstract Background Adult and paediatric basic life support (BLS) training are often conducted via group training with an accredited instructor every 24 months. Multiple studies have demonstrated a decline in the quality of cardio-pulmonary resuscitation (CPR) performed as soon as 3-month post-training. The ‘Resuscitation Quality Improvement’ (RQI) programme is a quarterly low-dose, high-frequency training, based around the use of manikins connected to a cart providing real-time and summative feedback. We aimed to evaluate the effects of the RQI Programme on CPR psychomotor skills in UK hospitals that had adopted this as a method of BLS training, and establish whether this program leads to increased compliance in CPR training. Methods The study took place across three adopter sites and one control site. Participants completed a baseline assessment without live feedback. Following this, participants at the adopter sites followed the RQI curriculum for adult CPR, or adult and infant CPR. The curriculum was split into quarterly training blocks, and live feedback was given on technique during the training session via the RQI cart. After following the curriculum for 12/24 months, participants completed a second assessment without live feedback. Results At the adopter sites, there was a significant improvement in the overall score between baseline and assessment for infant ventilations (N = 167, p < 0.001), adult ventilations (n = 129, p < 0.001), infant compressions (n = 163, p < 0.001) adult compressions (n = 205, p < 0.001), and adult CPR (n = 249, p < 0.001). There was no significant improvement in the overall score for infant CPR (n = 206, p = 0.08). Data from the control site demonstrated a statistically significant improvement in mean score for adult CPR (n = 22, p = 0.02), but not for adult compressions (N = 18, p = 0.39) or ventilations (n = 17, p = 0.08). No statistically significant difference in improvement of mean scores was found between the grouped adopter sites and the control site. The effect of the duration of the RQI curriculum on CPR performance appeared to be minimal in this data set. Compliance with the RQI curriculum varied by site, one site maintained hospital compliance at 90% over a 1 year period, however compliance reduced over time at all sites. Conclusions This data demonstrated an increased adherence with guidelines for high-quality CPR post-training with the RQI cart, for all adult and most infant measures, but not infant CPR. However, the relationship between a formalised quarterly RQI curriculum and improvements in resuscitation skills is not clear. It is also unclear whether the RQI approach is superior to the current classroom-based BLS training for CPR skill acquisition in the UK. Further research is required to establish how to optimally implement the RQI system in the UK and how to optimally improve hospital wide compliance with CPR training to improve the outcomes of in-hospital cardiac arrests.
