In the United States, cardiac monitors and defibrillators are available in all hospitals for use during in-hospital cardiac arrest. Furthermore, the use Automated External Defibrillators (AEDs) is encouraged for out-of-hospital arrests. In geographically remote, resource-limited areas, cardiac defibrillators may not be readily available. OBJECTIVE: This paper aims to evaluate the availability and efficacy of in-hospital cardiac defibrillation and discuss the potential global health goal of improving defibrillator access in Peru. METHODS: An online literature search was performed looking for key words. Retrieved articles, their references, and past literature reviews on the subject were screened for relevance. RESULTS: In the United States, overall survival to discharge for cardiac arrest is low; however, there is well-established evidence that the use of ACLS guidelines improves outcomes for cardiac arrest. Patients who present in shockable rhythms are more likely to survive than those in non-shockable rhythms when a defibrillator is available. Identification of the precipitating acute medical illness is a moderate predictor of both initial rhythm and chance of survival. In Peru, etiologies of in- hospital cardiac arrest is somewhat different. Few scientific data are available for cardiac arrest outcomes or defibrillator availability in Peru. CONCLUSION: Physicians practicing international medicine must recognize and adapt to differences in patient demographics and resource availability. In Peru and similar lesser-developed countries, basic public health need such as potable water and vaccines remain a priority. Efforts to improve outcomes for in-hospital arrest should focus on teaching high-quality CPR. When sufficient infrastructure is in place, improving access to defibrillators would be an appropriate next step.Item Software Annotation of Defibrillator Files: Ready for Prime Time?(2020-01-21) Gupta, Vishal; Schmicker, Robert H.; Owens, Pamela; Idris, Ahamed H.INTRODUCTION: High quality chest compressions are associated with improved outcomes after cardiac arrest. Defibrillators record important information about the quality of chest compressions during CPR and can be used in quality-improvement programs. Software made for reviewing defibrillator files can automatically annotate and measure chest compression metrics. However, evidence is limited regarding the accuracy of such measurements. OBJECTIVE: To compare chest compression fraction (CCF) and rate measurements made with software annotation vs. manual annotation vs. limited annotation of defibrillator files recorded during Out-of-Hospital Cardiac Arrest (OHCA) CPR. METHODS: This is a retrospective, observational study from the Dallas Fort-Worth site of the Resuscitation Outcomes Consortium. We reviewed chest compression waveforms from the bioimpedance channel of defibrillator recordings (Physio-Control Lifepak 12 and 15) of 100 OHCA patients enrolled in the DFW Cardiac Arrest Registry from 9/8/2018 to 3/9/2019. Included cases were ≥18 years, had presumed cardiac cause of arrest, and continuous chest compressions. We assessed chest compression waveforms from the time of initial CPR until the time the defibrillator was removed. A trained reviewer revised the software annotations in two separate ways: completely manual annotations and limited manual annotations, which required minimal revising. Software, manual, and limited annotation measurements were compared for CCF and rate using intraclass correlation coefficient (ICC) statistical analysis. RESULTS: Mean patient age was 63 years with 59% male. The mean (±SD) duration of CPR was 30.4 ± 10.6 min. Case mean CCF for software, manual, and limited annotation was 0.64 ± 0.19, 0.86 ± 0.07, and 0.81 ± 0.10, respectively. ICC for manual vs. limited annotation was good to excellent. Case mean rate for all three methods was between 108.1-108.6, with no significant difference between the methods. The software misidentified epochs before the start of chest compressions, after resuscitation ended, and after return of spontaneous circulation, resulting in low ICC for CCF when compared with manual and limited annotation. The ICC was excellent for compression rate because the software only counted epochs where chest compressions were actually given. CONCLUSIONS: Software annotation performed very well for chest compression rate. With respect to CCF, the difference between manual and software annotation measurements was clinically important, while manual vs. limited annotation compared favorably.Item [Southwestern News](2005-05-06) Lenocker, KaraItem [UT Southwestern Medical Center News](2007-07-25) Piloto, ConnieItem [UT Southwestern Medical Center News](2011-06-29) Rian, RussellItem [UT Southwestern Medical Center News](2009-09-29) Piloto, Connie
