Background An optimized protocol to help dispatchers identify potential cases of cardiac arrest and provide phone instructions for cardiopulmonary resuscitation (CPR) may increase the provision of bystander CPR, further improving the survival rate and neurological outcomes. Objective We assessed a revised dispatcher-assisted (DA)-CPR protocol with a continuous quality-improvement feature in a county fire department-based emergency medical services system. Methods This was a before-and-after intervention prospective study conducted in Taoyuan City, Taiwan. The participants were out-of-hospital cardiac arrest (OHCA) patients from November 2014 to February 2016. Interventional quality control started in August 2015. Approximately 10% of the telephone calls from these OHCA patients were reviewed. Results In total, 66 and 64 cases were included in the before- and after-intervention groups, respectively. No significant differences were observed in sex, age, day, and time of events, or languages spoken by the callers. After the intervention, we found significant improvements in the rates at which cardiac arrests were recognized (54.5% vs. 68.8%; p = 0.007) and normal breathing was checked (51.5% vs. 76.6%, p = 0.003). Moreover, the frequency with which DA-CPR was provided by the dispatchers improved significantly (50.0% vs. 72.7%; p = 0.046). Significant improvement in patient outcomes was observed with regard to 24-h survival (7.6% vs. 20.3%, p = 0.036) but not with regard to survival to discharge (3.0% vs. 10.9%, p = 0.076). Conclusions The study found this DA-CPR protocol, which includes continuous quality control, is promising as it improved the successful recognition of cardiac arrests.

Introduction: The psychomotor skill of cardiopulmonary resuscitation emphasized the importance of high-quality chest compression. This investigation examined the effect of self-debriefing and the different materials of debriefing during hands-on cardiopulmonary resuscitation practice for healthcare providers. Methods: This was a randomized controlled trial of a cardiopulmonary resuscitation training program involving emergency medical technicians in northern Taiwan. Participants were blinded to the study purpose and were allocated randomly using the black envelope method. All participants completed a 2-min pre-test of hands-only cardiopulmonary resuscitation using a manikin. Those who were allocated to the control group received self-debriefing with knowledge of pre-test result. Those who were allocated to the experimental group received self-debriefing with an additional biomechanical information of performance of chest compression. A post-test was performed 30 min after the pre-test. Results: A total of 88 participants were enrolled with 44 in each group. There was significant difference of cardiopulmonary resuscitation quality after self-debriefing among all participants (pre- vs post-test adequate rate, 54.7% vs 67.5%, p = 0.028; adequate depth, 41.2% vs 69.5%, p Conclusion: Self-debriefing improved hands-only cardiopulmonary resuscitation quality whether or not biomechanical information of performance of chest compression was given.

Percutaneous coronary interventions (PCIs) within a door-to-balloon timing of 90 min have greatly decreased mortality and morbidity of ST-elevation myocardial infarction (STEMI) patients. Post-PCI, they are routinely transferred into the coronary care unit (CCU) regardless of the severity of their condition, resulting in frequent CCU overcrowding. This study assesses the feasibility of step-down units (SDUs) as an alternative to CCUs in the management of STEMI patients after successful PCI, to alleviate CCU overcrowding. Criteria of assessment include in-hospital complications, length of stay, cost-effectiveness, and patient outcomes up to a year after discharge from hospital. A retrospective case–control study was done using data of 294 adult STEMI patients admitted to the emergency departments of two training and research hospitals and successfully underwent primary PCI from 1 January 2014 to 31 December 2015. Patients were followed up for a year post-discharge. Student t test and χ2 test were done as univariate analysis to check for statistical significance of p
