Survivors of Sudden Cardiac Arrest Presenting With Pulseless Electrical Activity: Clinical Substrate, Triggers, Long-Term Prognosis. JACC Clin Electrophysiol 2022; 8:1260-1270. [PMID: 36057529 DOI: 10.1016/j.jacep.2022.06.022] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 06/13/2022] [Accepted: 06/28/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND The proportion of sudden cardiac arrest (SCA) presenting as pulseless electrical activity (PEA) is rising, and survival remains low. The pathophysiology of PEA-SCA is poorly understood, and current clinical practice lacks specific options for the management of survivors. OBJECTIVES In this study, the authors sought to investigate clinical profile, triggers, and long-term prognosis in survivors of SCA presenting with PEA. METHODS The community-based Oregon SUDS (Sudden Unexpected Death Study) (since 2002) and Ventura PRESTO (Prediction of Sudden Death in Multi-ethnic Communities) (since 2015) studies prospectively ascertain all out-of-hospital SCAs of likely cardiac etiology. Lifetime clinical history and detailed evaluation of SCA events is available. We evaluated all SCA survivors with PEA as the presenting rhythm. RESULTS The study population included 201 PEA-SCA survivors. Of these, 97 could be contacted for access to their clinical records. Among the latter, the mean age was 67 ± 17 years and 58 (60%) were male. After in-hospital examinations, 29 events (30%) were associated with acute myocardial infarction, and 5 (5%) had bradyarrhythmias. Among the remaining 63 patients (65%), specific triggers remained undetermined, although 31 (49%) had a previous history of heart failure. Of the 201 overall survivors, 91 (45%) were deceased after a mean follow-up of 4.2 ± 4.0 years. Survivors under the age of 40 years had an excellent long-term prognosis. CONCLUSIONS Survivors of PEA-SCA are a heterogeneous group with high prevalence of multiple comorbidities, especially heart failure. Surprisingly good long-term survival was observed in young individuals. Acute myocardial infarction as the precipitating event was common, but triggers remained undetermined in the majority. Provision of individualized care to PEA survivors requires a renewed investigative focus on PEA-SCA.

Clinical Validation of Cardiac Arrest Hospital Prognosis (CAHP) Score and MIRACLE2 Score to Predict Neurologic Outcomes after Out-of-Hospital Cardiac Arrest. Healthcare (Basel) 2022; 10:healthcare10030578. [PMID: 35327059 PMCID: PMC8950818 DOI: 10.3390/healthcare10030578] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 03/18/2022] [Accepted: 03/18/2022] [Indexed: 11/17/2022] Open
Abstract
Background. Out-of-hospital cardiac arrest (OHCA) remains a challenge for emergency physicians, given the poor prognosis. In 2020, MIRACLE2, a new and easier to apply score, was established to predict the neurological outcome of OHCA. Objective. The aim of this study is to compare the discrimination of MIRACLE2 score with cardiac arrest hospital prognosis (CAHP) score for OHCA neurologic outcomes. Methods. This retrospective cohort study was conducted between January 2015 and December 2019. Adult patients (>17 years) with cardiac arrest who were brought to the hospital by an emergency medical service crew were included. Deaths due to trauma, burn, drowning, resuscitation not initiated due to pre-ordered “do not resuscitate” orders, and patients who did not achieve return of spontaneous circulation were excluded. Receiver operating characteristic curve analysis with Youden Index was performed to calculate optimal cut-off values for both scores. Results. Overall, 200 adult OHCA cases were analyzed. The threshold of the MIRACLE2 score for favorable neurologic outcomes was 5.5, with an area under the curve (AUC) value of 0.70 (0.61−0.80, p < 0.001); the threshold of the CAHP score was 223.4, with an AUC of 0.77 (0.68−0.86, p < 0.001). On setting the MIRACLE2 score cut-off value, we documented 64.7% sensitivity (95% confidence interval [CI], 56.9−71.9%), 66.7.0% specificity (95% CI, 48.2−82.0%), 90.8% positive predictive value (PPV; 95% CI, 85.6−94.2%), and 27.2% negative predictive value (NPV; 95% CI, 21.4−33.9%). On establishing a CAHP cut-off value, we observed 68.2% sensitivity (95% CI, 60.2−75.5%), 80.6% specificity (95% CI, 62.5−92.6%), 94.6% PPV (95% CI, 88.6%−98.0%), and 33.8% NPV (95% CI, 23.2−45.7%) for unfavorable neurologic outcomes. Conclusions. The CAHP score demonstrated better discrimination than the MIRACLE2 score, affording superior sensitivity, specificity, PPV, and NPV; however, the CAHP score remains relatively difficult to apply. Further studies are warranted to establish scores with better discrimination and ease of application.

Abstract
PURPOSE OF REVIEW To describe the epidemiology, prognostication, and treatment of out- and in-hospital cardiac arrest (OHCA and IHCA) in elderly patients. RECENT FINDINGS Elderly patients undergoing cardiac arrest (CA) challenge the appropriateness of attempting cardiopulmonary resuscitation (CPR). Current literature suggests that factors traditionally associated with survival to hospital discharge and neurologically intact survival after CA cardiac arrest in general (e.g. presenting ryhthm, bystander CPR, targeted temperature management) may not be similarly favorable in elderly patients. Alternative factors meaningful for outcome in this special population include prearrest functional status, comorbidity load, the specific age subset within the elderly population, and CA location (i.e., nursing versus private home). Age should therefore not be a standalone criterion for withholding CPR. Attempts to perform CPR in an elderly patient should instead stem from a shared decision-making process. SUMMARY An appropriate CPR attempt is an attempt resulting in neurologically intact survival. Appropriate CPR in elderly patients requires better risk classification. Future research should therefore focus on the associations of specific within-elderly age subgroups, comorbidities, and functional status with neurologically intact survival. Reporting must be standardized to enable such evaluation.

Siaw-Frimpong M, Touray S, Sefa N. Capacity of intensive care units in Ghana. J Crit Care 2020; 61:76-81. [PMID: 33099204 PMCID: PMC7560159 DOI: 10.1016/j.jcrc.2020.10.009] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 09/28/2020] [Accepted: 10/12/2020] [Indexed: 01/09/2023]
Abstract
Purpose To document the equipment, resource and bed capacity of Intensive Care Units (ICUs) in the Republic of Ghana. Materials and methods Cross-sectional observational study of all operating ICUs in Ghana. Sixteen operating ICUs in 9 hospitals were identified and surveyed (13 adult and 3 pediatric ICUs). Results There were a total of 113 adult and 36 pediatric ICU beds for a population of 30 million, (0.5 ICU beds per 100,000 people). The median number of staffed ICU beds and ventilators were 5 (IQR 4–6), and 4 (IQR 3–5) respectively. There were 2 pediatric and 6 adult intensivists practicing in the country. About half of the ICUs (56%) were staffed solely by non-intensivist providers. While there is adequate nursing support and availability of essential critical care medications, the current financing model for critical care delivery creates a significant barrier for most patients. Conclusion Ghana has a significant shortage of critical care beds that are inequitably distributed across the country and a shortfall of intensivists to staff ICUs. A holistic approach that focuses on the key bottlenecks to quality improvement would be required to improve the capacity and quality of critical care delivery. There were a total of 113 adult and 36 pediatric critical care beds for a population of 30 million people in Ghana. In February 2020, Ghana had a total Critical Care bed capacity of 0.5 ICU beds per 100,000 people. There were 16 operational ICUs across 9 institutions, of which 13 were adult and 3 were pediatric ICUs. There were 8 intensivists (5 on loan from the Cuban Government) in the whole country.

Lundin A, Karlsson T, Herlitz J, Lundgren P, Rylander C. The association between duration of mechanical ventilation and survival in post cardiac arrest patients. Resuscitation 2020; 148:145-151. [PMID: 32004666 DOI: 10.1016/j.resuscitation.2020.01.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Revised: 12/17/2019] [Accepted: 01/13/2020] [Indexed: 10/25/2022]
Abstract
PURPOSE To assess the association between the duration of mechanical ventilation during post resuscitation care and 30-day survival after cardiac arrest. METHODS We conducted a retrospective observational study using data from two national registries. Comatose cardiac arrest patients admitted to general intensive care in Swedish hospitals between 2011 and 2016 were eligible. Based on the median duration of mechanical ventilation for patients who did not survive to hospital discharge, used as a proxy for the endurance of post resuscitation care, the hospitals were divided into four ordered groups for which association with 30-day survival was analyzed. RESULTS In total, 5.113 patients in 56 hospitals were included. Median duration of mechanical ventilation for patients who did not survive to hospital discharge ranged from 17 h in hospital group 1-51 hours in hospital group 4. After adjustment for baseline characteristics, 30-day survival in the entire cohort was positively and independently associated with ordered hospital group: (adjusted odds ratio (95%CI); 1.12 (1.02,1.23); p = 0.02). Thus, hospitals with a longer duration of mechanical ventilation among non-survivors had better survival rate among patients admitted to ICU after a cardiac arrest. However, in a secondary analysis restricted to patients with length of stay in the intensive care unit ≥ 48 h, there was no significant association between 30-day survival and ordered hospital group. CONCLUSION A tendency for longer duration of post resuscitation care in the ICU was associated with higher 30-day survival in comatose patients admitted to intensive care after cardiac arrest.
