Boulton AJ, Abelairas-Gómez C, Olaussen A, Skrifvars MB, Greif R, Yeung J. Cardiac arrest centres for patients with non-traumatic cardiac arrest: a systematic review. Resuscitation 2024:110387. [PMID: 39242018 DOI: 10.1016/j.resuscitation.2024.110387] [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: 05/01/2024] [Revised: 08/20/2024] [Accepted: 08/31/2024] [Indexed: 09/09/2024]
Abstract
INTRODUCTION Regionalisation and organised pathways of care using specialist centre hospitals can improve outcomes for critically ill patients. Cardiac arrest centre hospitals (CAC) may optimise the delivery of post-resuscitation care. The International Liaison Committee on Resuscitation (ILCOR) has called for a review of the current evidence base. AIM This systematic review aimed to assess the effect of cardiac arrest centres for patients with non-traumatic cardiac arrest. METHODS Articles were included if they met the prospectively registered (PROSPERO) inclusion criteria. These followed the PICOST framework for ILCOR systematic reviews. A strict definition for a CAC was used, reflecting current position statements and clinical practice. MEDLINE, Embase and the Cochrane Library were searched using pre-determined criteria from inception to 31 December 2023. Risk of bias was assessed using Cochrane's Risk of Bias tool and ROBINS-I. The certainty of evidence for each outcome was assessed using the GRADE approach. Substantial heterogeneity precluded meta-analysis and a narrative synthesis with visualisation of effect estimates in forest plots was performed. RESULTS Sixteen studies met eligibility criteria, including data on over 145,000 patients. One was a randomised controlled trial (RCT) at low risk of bias and the remainder were observational studies, all at moderate or serious risk of bias. All studies included adults with out-of-hospital cardiac arrest. One study used initial shockable rhythm as an inclusion criterion and most studies (n=12) included patients regardless of prehospital ROSC status. Two studies, including the RCT, excluded patients with ST elevation. Survival to hospital discharge with a favourable neurological outcome was reported by 11 studies and favoured CAC care in all observational studies, but the RCT showed no difference. Survival to 30 days with a favourable neurological outcome was reported by two observational studies and favoured CAC care in both. Survival to hospital discharge was reported by 13 observational studies and generally favoured CAC care. Survival to 30 days was reported by two studies, where the observational study favoured CAC care, but the RCT showed no difference. CONCLUSION This review supports a weak recommendation that adults with out-of-hospital cardiac arrest are cared for at CACs based on very low certainty of evidence. Randomised evidence has not confirmed the benefits of CACs found in observational studies, however this RCT was a single trial in a very specific setting and a population without ST elevation on post-ROSC ECG. The role of CACs in shockable and non-shockable subgroups, direct versus secondary transfer, as well as the impact of increased transport time and bypassing local hospitals remains unclear.

Association of High-Volume Centers With Survival Outcomes Among Patients With Nontraumatic Out-of-Hospital Cardiac Arrest: A Systematic Review and Meta-Analysis. JAMA Netw Open 2022; 5:e2214639. [PMID: 35639377 PMCID: PMC9157264 DOI: 10.1001/jamanetworkopen.2022.14639] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 04/13/2022] [Indexed: 11/29/2022] Open
Abstract
Importance Although high volume of cases of out-of-hospital cardiac arrest (OHCA) is a key feature of cardiac arrest centers, which have proven survival benefit, the role of center volume as an independent variable associated with improved outcomes is unclear. Objective To assess the association of high-volume centers with survival and neurological outcomes in nontraumatic OHCA. Data Sources Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched from inception to October 11, 2021, for studies including adult patients with nontraumatic OHCA who were treated at high-volume vs non-high-volume centers. Study Selection Randomized clinical trials, nonrandomized studies of interventions, prospective cohort studies, and retrospective cohort studies were selected that met the following criteria: (1) adult patients with OHCA of nontraumatic etiology, (2) comparison of high-volume with low-volume centers, (3) report of a volume-outcome association, and (4) report of outcomes of interest. At least 2 authors independently reviewed each article, blinded to each other's decision. Data Extraction and Synthesis Data abstraction and quality assessment were independently conducted by 2 authors. Meta-analyses were performed for adjusted odds ratios (aORs) and crude ORs using a random-effects model. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Main Outcomes and Measures Survival and good neurological outcomes according to the Cerebral Performance Categories Scale at hospital discharge or 30 days. Results A total of 16 studies involving 82 769 patients were included. Five studies defined high volume as 40 or more cases of OHCA per year; 3 studies defined high volume as greater than 100 cases of OHCA per year. All other studies differed in definitions. Survival to discharge or 30 days improved with treatment at high-volume centers, regardless of whether aORs (1.28 [95% CI, 1.00-1.64]) or crude ORs (1.43 [95% CI, 1.09-1.87]) were pooled. There was no association between center volume and good neurological outcomes at 30 days or hospital discharge in patients with OHCA (aOR, 0.96 [95% CI, 0.77-1.20]). Conclusions and Relevance In this meta-analysis and systematic review, care at high-volume centers was associated with improved survival outcomes, even after adjustment for potential confounders, but was not associated with improved neurological outcomes for patients with nontraumatic OHCA. More studies evaluating the relative importance of center volume compared with other variables (eg, the availability of treatment modalities) associated with survival outcomes in patients with OHCA are required.

Abstract
Out-of-hospital cardiac arrest is a global public health issue experienced by ≈3.8 million people annually. Only 8% to 12% survive to hospital discharge. Early defibrillation of shockable rhythms is associated with improved survival, but ensuring timely access to defibrillators has been a significant challenge. To date, the development of public-access defibrillation programs, involving the deployment of automated external defibrillators into the public space, has been the main strategy to address this challenge. Public-access defibrillator programs have been associated with improved outcomes for out-of-hospital cardiac arrest; however, the devices are used in <3% of episodes of out-of-hospital cardiac arrest. This scientific statement was commissioned by the International Liaison Committee on Resuscitation with 3 objectives: (1) identify known barriers to public-access defibrillator use and early defibrillation, (2) discuss established and novel strategies to address those barriers, and (3) identify high-priority knowledge gaps for future research to address. The writing group undertook systematic searches of the literature to inform this statement. Innovative strategies were identified that relate to enhanced public outreach, behavior change approaches, optimization of static public-access defibrillator deployment and housing, evolved automated external defibrillator technology and functionality, improved integration of public-access defibrillation with existing emergency dispatch protocols, and exploration of novel automated external defibrillator delivery vectors. We provide evidence- and consensus-based policy suggestions to enhance public-access defibrillation and guidance for future research in this area.

Abstract
Background The role of cardiac arrest centers (CACs) in out‐of‐hospital cardiac arrest care systems is continuously evolving. Interpretation of existing literature is limited by heterogeneity in CAC characteristics and types of patients transported to CACs. This study assesses the impact of CACs on survival in out‐of‐hospital cardiac arrest according to varying definitions of CAC and prespecified subgroups. Methods and Results Electronic databases were searched from inception to March 9, 2021 for relevant studies. Centers were considered CACs if self‐declared by study authors and capable of relevant interventions. Main outcomes were survival and neurologically favorable survival at hospital discharge or 30 days. Meta‐analyses were performed for adjusted odds ratio (aOR) and crude odds ratios. Thirty‐six studies were analyzed. Survival with favorable neurological outcome significantly improved with treatment at CACs (aOR, 1.85 [95% CI, 1.52–2.26]), even when including high‐volume centers (aOR, 1.50 [95% CI, 1.18–1.91]) or including improved‐care centers (aOR, 2.13 [95% CI, 1.75–2.59]) as CACs. Survival significantly increased with treatment at CACs (aOR, 1.92 [95% CI, 1.59–2.32]), even when including high‐volume centers (aOR, 1.74 [95% CI, 1.38–2.18]) or when including improved‐care centers (aOR, 1.97 [95% CI, 1.71–2.26]) as CACs. The treatment effect was more pronounced among patients with shockable rhythm (P=0.006) and without prehospital return of spontaneous circulation (P=0.005). Conclusions were robust to sensitivity analyses, with no publication bias detected. Conclusions Care at CACs was associated with improved survival and neurological outcomes for patients with nontraumatic out‐of‐hospital cardiac arrest regardless of varying CAC definitions. Patients with shockable rhythms and those without prehospital return of spontaneous circulation benefited more from CACs. Evidence for bypassing hospitals or interhospital transfer remains inconclusive.

Abstract
INTRODUCTION Out of hospital cardiac arrest (OHCA) patients are often transported to the closest emergency department (ED) or cardiac center for initial stabilization and may be transferred for further care. We investigated the effects of delay to transfer on in hospital mortality at a receiving facility. METHODS We included OHCA patients transported from the ED by a single critical care transport service to a quaternary care facility between 2010 and 2018. We calculated dwell time as time from arrest to critical care transport team contact. We abstracted demographics, arrest characteristics, and interventions started prior to transport arrival. For the primary analysis, we used logistic regression to determine the association of dwell time and in-hospital mortality. As secondary outcomes we investigated for associations of dwell time and mortality within 24 h of arrival, proximate cause of death among decedents, arterial pH and lactate on arrival, sum of worst SOFA subscales within 24 h of arrival, and rearrest during interfacility transport. RESULTS We included 572 OHCA patients transported from an outside ED to our facility. Median dwell time was 113 (IQR = 85-159) minutes. Measured in 30 min epochs, increasing dwell time was not associated with in-hospital mortality, 24-h mortality, cause of death and initial pH, but was associated with lower 24-h SOFA score (p = 0.01) and lower initial lactate (p = 0.03). Rearrest during transport was rare (n = 29, 5%). Dwell time was associated with lower probability of rearrest during transport (OR = 0.847, (95% CI 0.68-1.01), p = 0.07). CONCLUSIONS Dwell time was not associated with in-hospital mortality. Rapid transport may be associated with risk of rearrest. Prospective data are needed to clarify optimal patient stabilization and transport strategies.

Abstract
The European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM) have collaborated to produce these post-resuscitation care guidelines for adults, which are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. The topics covered include the post-cardiac arrest syndrome, diagnosis of cause of cardiac arrest, control of oxygenation and ventilation, coronary reperfusion, haemodynamic monitoring and management, control of seizures, temperature control, general intensive care management, prognostication, long-term outcome, rehabilitation, and organ donation.

Care at critical care medical centers is associated with improved outcomes in patients with accidental hypothermia: a historical cohort study from the J-Point registry. Acute Med Surg 2020; 7:e578. [PMID: 33133614 PMCID: PMC7590663 DOI: 10.1002/ams2.578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 08/23/2020] [Accepted: 09/14/2020] [Indexed: 11/24/2022] Open
Abstract
Aim The recommendation that patients with accidental hypothermia should be transported to specialized centers that can provide extracorporeal life support has not been validated, and the efficacy remains unclear. Methods This was a multicenter retrospective cohort study of patients with a body temperature of ≤35°C presenting at the emergency department of 12 hospitals in Japan between April 2011 and March 2016. We divided the patients into two groups based on the point of care delivery: critical care medical center (CCMC) or non‐CCMC. The primary outcome of this study was in‐hospital death. In‐hospital death was compared using a multivariable logistic regression analysis. Subgroup analyses were carried out according to patients with severe hypothermia (<28°C) or systolic blood pressure (sBP) of <90 mmHg. Results A total of 537 patients were included, 413 patients (76.9%) in the CCMC group and 124 patients (23.1%) in the non‐CCMC group. The in‐hospital death rate was lower in the CCMC group than in the non‐CCMC group (22.3% versus 31.5%, P < 0.001). The multivariable logistic regression analysis showed that the adjusted odds ratio (AOR) of the CCMC group was 0.54 (95% confidence interval, 0.32–0.90). In subgroup analyses, patients with systolic blood pressure <90 mmHg in the CCMC group were less likely to experience in‐hospital death (AOR 0.36; 95% CI, 0.23–0.56). However, no such association was observed among patients with severe hypothermia (AOR 1.08; 95% CI, 0.63–1.85). Conclusions Our multicenter study indicated that care at a CCMC was associated with improved outcomes in patients with accidental hypothermia.

Abstract
Emergency clinicians often resuscitate cardiac arrest patients, and after acute resuscitation, clinicians face multiple decisions regarding disposition. Recent evidence suggests that out-of-hospital cardiac arrest patients with return of spontaneous circulation have higher odds of survival to hospital discharge, long-term survival, and improved functional outcomes when treated at centers that can provide advanced multidisciplinary care. For community clinicians, a high volume cardiac arrest center may be hours away. While current guidelines recommend against neurological prognostication in the first hours or days after return of spontaneous circulation, there are early findings suggestive of irrecoverable brain injury in which the patient would receive no benefit from transfer. In this Concepts article, we describe a simplified approach to quickly evaluate neurological status in cardiac arrest patients and identify findings concerning for irrecoverable brain injury. Characteristics of the arrest and resuscitation, initial neurological assessment, and brain computed tomography together can identify patients with high likelihood of irrecoverable anoxic injury. Patients who may benefit from centers with access to continuous electroencephalography are discussed. This approach can be used to identify patients who may benefit from rapid transfer to cardiac arrest centers versus those who may benefit from care close to home. Risk stratification also can provide realistic expectations for recovery to families.

Abstract
The International Liaison Committee on Resuscitation has initiated a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation science. This is the third annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. It addresses the most recent published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. This summary addresses the role of cardiac arrest centers and dispatcher-assisted cardiopulmonary resuscitation, the role of extracorporeal cardiopulmonary resuscitation in adults and children, vasopressors in adults, advanced airway interventions in adults and children, targeted temperature management in children after cardiac arrest, initial oxygen concentration during resuscitation of newborns, and interventions for presyncope by first aid providers. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the certainty of the evidence on the basis of the Grading of Recommendations, Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence to Decision Framework Highlights sections. The task forces also listed priority knowledge gaps for further research.

Abstract
Survival after out-of-hospital cardiac arrest requires an integrated system of care (chain of survival) between the community elements responding to an event and the healthcare professionals who continue to care for and transport the patient for appropriate interventions. As a result of the dynamic nature of the prehospital setting, coordination and communication can be challenging, and identification of methods to optimize care is essential. This 2019 focused update to the American Heart Association systems of care guidelines summarizes the most recent published evidence for and recommendations on the use of dispatcher-assisted cardiopulmonary resuscitation and cardiac arrest centers. This article includes the revised recommendations that emergency dispatch centers should offer and instruct bystanders in cardiopulmonary resuscitation during out-of-hospital cardiac arrest and that a regionalized approach to post-cardiac arrest care may be reasonable when comprehensive postarrest care is not available at local facilities.

Abstract
AIM To perform a systematic review to answer 'In adults with attempted resuscitation after non-traumatic cardiac arrest does care at a specialised cardiac arrest centre (CAC) compared to care in a healthcare facility not designated as a specialised cardiac arrest centre improve patient outcomes?' METHODS The PRISMA guidelines were followed. We searched bibliographic databases (Embase, MEDLINE and the Cochrane Library (CENTRAL)) from inception to 1st August 2018. Randomised controlled trials (RCTs) and non-randomised studies were eligible for inclusion. Two reviewers independently scrutinized studies for relevance, extracted data and assessed quality of studies. Risk of bias of studies and quality of evidence were assessed using ROBINS-I tool and GRADEpro respectively. Primary outcomes were survival to 30 days with favourable neurological outcomes and survival to hospital discharge with favourable neurological outcomes. Secondary outcomes were survival to 30 days, survival to hospital discharge and return of spontaneous circulation (ROSC) post-hospital arrival for patients with ongoing resuscitation. This systematic review was registered in PROSPERO (CRD 42018093369) RESULTS: We included data from 17 observational studies on out-of-hospital cardiac arrest (OHCA) patients in meta-analyses. Overall, the certainty of evidence was very low. Pooling data from only adjusted analyses, care at CAC was not associated with increased likelihood of survival to 30 days with favourable neurological outcome (OR 2.92, 95% CI 0.68-12.48) and survival to 30 days (OR 2.14, 95% CI 0.73-6.29) compared to care at other hospitals. Whereas patients cared for at CACs had improved survival to hospital discharge with favourable neurological outcomes (OR 2.22, 95% CI 1.74-2.84) and survival to hospital discharge (OR 1.85, 95% CI 1.46-2.34). CONCLUSIONS Very low certainty of evidence suggests that post-cardiac arrest care at CACs is associated with improved outcomes at hospital discharge. There remains a need for high quality data to fully elucidate the impact of CACs.

Abstract
BACKGROUND Patients treated at 24/7 percutaneous coronary intervention (PCI) centres following out-of-hospital cardiac arrest (OHCA) have better outcomes than those treated at non-24/7 PCI centres. However, variation in outcomes between 24/7 PCI centres is not well studied. OBJECTIVES To evaluate variation in outcomes among 24/7 PCI centres and to assess stability of 24/7 PCI centre performance. METHODS Adult patients in the California Office of Statewide Health Planning and Development Patient Discharge Database with a "present on admission" diagnosis of cardiac arrest admitted to a 24/7 PCI centre from 2011 to 2015 were included. Primary outcome was good neurologic recovery at hospital discharge. Secondary outcomes were survival to hospital discharge, cardiac catheterisation, and DNR orders within 24 h. Data were analysed using mixed effects logistic regression models. Hospitals were ranked each year and overall. RESULTS Of 27,122 patients admitted to 128 24/7 PCI centres, 41% (11,184) survived and 27% (7188) had good neurologic recovery. Adjusted rates of good neurologic recovery (18%-39%; p,0.001), survival (32%-51%; p < 0.0001), cardiac catheterisation (11%-49%; p < 0.0001) and DNR orders within 24 h (4.8%-49%; p < 0.0001) varied between 24/7 PCI centres. For the 26 hospitals with mean good neurologic rankings in the top or bottom tenth during 2011-2013, 14 (54%) remained in their respective tenth for 2014-2015. CONCLUSION Significant variation exists between 24/7 PCI centres in good neurologic recovery following OHCA and persists over time. Future studies should evaluate hospital-level factors that contribute to these differences in outcomes between 24/7 PCI centres.

Abstract
BACKGROUND Sex, race, and insurance status are associated with treatment and outcomes in several cardiovascular diseases. These disparities, however, have not been well-studied in out-of-hospital cardiac arrest (OHCA). OBJECTIVE Our objective was to evaluate the association of patient sex, race, and insurance status with hospital treatments and outcomes following OHCA. METHODS We studied adult patients in the 2011-2015 California Office of Statewide Health Planning and Development (OSHPD) Patient Discharge Database with a "present on admission" diagnosis of cardiac arrest (ICD-9-CM 427.5). Insurance status was classified as private, Medicare, and Medi-Cal/government/self-pay. Our primary outcome was good neurologic recovery at hospital discharge, which was determined by discharge disposition. Secondary outcomes were survival to hospital discharge, treatment at a 24/7 percutaneous coronary intervention (PCI) center, "do not resuscitate" orders within 24 h of admission, and cardiac catheterization during hospitalization. Data were analyzed with hierarchical multiple logistic regression models. RESULTS We studied 38,163 patients in the OSHPD database. Female sex, non-white race, and Medicare insurance status were independently associated with worse neurologic recovery [OR 0.94 (0.89-0.98), 0.93 (0.88-0.98), and 0.85 (0.79-0.91), respectively], lower rates of treatment at a 24/7 PCI center [OR 0.89 (0.85-0.93), 0.88 (0.85-0.93), and 0.87 (0.82-0.94), respectively], and lower rates of cardiac catheterization [OR 0.61 (0.57-0.65), 0.90 (0.84-0.97), and 0.44 (0.40-0.48), respectively]. Female sex, white race, and Medicare insurance were associated with DNR orders within 24 h of admission [OR 1.16 (1.10-1.23), 1.14 (1.07-1.21), and 1.25 (1.15-1.36), respectively]. CONCLUSIONS Sex, race, and insurance status were independently associated with post-arrest care interventions, patient outcomes and treatment at a 24/7 PCI center. More studies are needed to fully understand the causes and implications of these disparities.

Abstract
Background
Each year, approximately 30,000 people have an out-of-hospital cardiac arrest (OHCA) that is treated by UK ambulance services. Across all cases of OHCA, survival to hospital discharge is less than 10%. Acute coronary syndrome (ACS) is a common cause of OHCA.
Objectives
To explore factors that influence survival in patients who initially survive an OHCA attributable to ACS.
Data source
Data collected by the Myocardial Ischaemia National Audit Project (MINAP) between 2003 and 2015.
Participants
Adult patients who had a first OHCA attributable to ACS and who were successfully resuscitated and admitted to hospital.
Main outcome measures
Hospital mortality, neurological outcome at hospital discharge, and time to all-cause mortality.
Methods
We undertook a cohort study using data from the MINAP registry. MINAP is a national audit that collects data on patients admitted to English, Welsh and Northern Irish hospitals with myocardial ischaemia. From the data set, we identified patients who had an OHCA. We used imputation to address data missingness across the data set. We analysed data using multilevel logistic regression to identify modifiable and non-modifiable factors that affect outcome.
Results
Between 2003 and 2015, 1,127,140 patient cases were included in the MINAP data set. Of these, 17,604 OHCA cases met the study inclusion criteria. Overall hospital survival was 71.3%. Across hospitals with at least 60 cases, hospital survival ranged from 34% to 89% (median 71.4%, interquartile range 60.7–76.9%). Modelling, which adjusted for patient and treatment characteristics, could account for only 36.1% of this variability. For the primary outcome, the key modifiable factors associated with reduced mortality were reperfusion treatment [primary percutaneous coronary intervention (pPCI) or thrombolysis] and admission under a cardiologist. Admission to a high-volume cardiac arrest hospital did not influence survival. Sensitivity analyses showed that reperfusion was associated with reduced mortality among patients with a ST elevation myocardial infarction (STEMI), but there was no evidence of a reduction in mortality in patients who did not present with a STEMI.
Limitations
This was an observational study, such that unmeasured confounders may have influenced study findings. Differences in case identification processes at hospitals may contribute to an ascertainment bias.
Conclusions
In OHCA patients who have had a cardiac arrest attributable to ACS, there is evidence of variability in survival between hospitals, which cannot be fully explained by variables captured in the MINAP data set. Our findings provide some support for the current practice of transferring resuscitated patients with a STEMI to a hospital that can deliver pPCI. In contrast, it may be reasonable to transfer patients without a STEMI to the nearest appropriate hospital.
Future work
There is a need for clinical trials to examine the clinical effectiveness and cost-effectiveness of invasive reperfusion strategies in resuscitated OHCA patients of cardiac cause who have not had a STEMI.

Outcomes of ST Elevation Myocardial Infarction Complicated by Out-of-Hospital Cardiac Arrest (from the Los Angeles County Regional System). Am J Cardiol 2017; 120:729-733. [PMID: 28728743 DOI: 10.1016/j.amjcard.2017.06.010] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Revised: 05/16/2017] [Accepted: 06/01/2017] [Indexed: 01/01/2023]
Abstract
The objective of this study was to evaluate the time to primary percutaneous coronary intervention (PCI) and the outcome for patients with ST elevation myocardial infarction (STEMI) complicated by out-of-hospital cardiac arrest (OHCA). In this regional system, all patients with STEMI and/or OHCA with return of spontaneous circulation were transported to STEMI Receiving Centers. The outcomes registry was queried for patients with STEMI with underwent primary PCI from April 2011 to December 2014. Patients with STEMI complicated by OHCA were compared with a reference group of STEMI without OHCA. The primary end point was the first medical contact-to-device time. Of 4,729 patients with STEMI who underwent primary PCI, 422 patients (9%) suffered OHCA. Patients with OHCA were on average 2 years (95% confidence interval 0.7 to 3.0) older and had a slightly higher male predominance. The first medical contact-to-device time was longer in STEMI with OHCA compared with STEMI alone (94 ± 37 vs. 86 ± 34 minutes, p < 0.0001). In-hospital mortality was higher after OHCA, 38% versus 6% in STEMI alone, odds ratio 6.3 (95% confidence interval 5.3 to 7.4). Among OHCA survivors, 193 (73%) were discharged with a cerebral performance category score of 1 or 2. In conclusion, despite longer treatment intervals, neurologic outcome was good in nearly half of the surviving patients with STEMI complicated by OHCA, suggesting that these patients can be effectively treated with primary PCI in a regionalized system of care.

Abstract
BACKGROUND Large regional hospitals achieve good outcomes for patients with complex conditions. However, recent studies have suggested that some patient groups might not benefit from treatment in higher-level trauma centers. OBJECTIVE To test the hypothesis that older adults with isolated hip fractures experience delayed surgical treatment and worse clinical outcomes when treated in higher-level trauma centers. RESEARCH DESIGN Retrospective cohort study using a statewide longitudinal database that captured 98% of inpatients within California (2007-2011). SUBJECTS All older adults (aged 65 y and above) admitted with an isolated hip fracture who did not require interhospital transfer. MEASURES Days to operation, length of stay, inhospital mortality, 30-day risk of unplanned readmission, 30-day venous thromboembolism, decubitus ulcers, and pneumonia. RESULTS There were 91,401 patients, 6.1% of whom were treated in a level 1 trauma center (L1TC), 17.7% in a level 2 trauma center (L2TC), and 70.2% in a nontrauma center (NTC). Within multivariable logistic and generalized linear regression models, patients treated in L1TCs underwent surgery later (predicted mean difference: 0.30 d; 95% CI, 0.08-0.53), had prolonged inpatient stays (0.99 d, 0.40-1.59), and had higher odds of both 30-day readmission (aOR=1.62; 95% CI, 1.35-1.93) and venous thromboembolism (aOR=1.32, 1.01-1.74) relative to NTCs. There were no differences in mortality, decubitus ulcers, or pneumonias. L2TCs were not different from NTCs across any of the measured outcomes. CONCLUSIONS Older adults with hip fractures may be disadvantaged in L1TCs. Further research should aim to develop our understanding of this disparity to ensure that all patient groups benefit from the resources and expertise available within these hospitals.

Abstract
OBJECTIVE Predicting the outcome of out-of-hospital cardiac arrest (OHCA) patients is crucial. We examined hospital characteristics and parameters of emergency medical service (including scene time interval and direct ambulance delivery to intensive heart hospitals) as survival or outcome predictors. STUDY DESIGN Data from 546 consecutive OHCA shockable patients treated between January 2012 and December 2015 in Taoyuan City (Taiwan, ROC) were collected. In addition to demographic data, location of arrest, initial rhythm, availability of a hospital with or without 24/7 percutaneous coronary intervention (PCI), emergency medical service (EMS) time, provision of cardiopulmonary resuscitation by a bystander, presence of a witness at collapse, and level of life support were analysed. RESULTS Multivariate analysis showed that hospitalisation with immediate PCI availability was an independent predictor (OR: 4.32; 95% CI: 1.27-14.70) solely for the outcome of survival until discharge. The presence of a witness while collapsing (OR: 3.52; 95% CI: 1.03-11.98), EMS response time (OR: 0.83; 95% CI: 0.70-0.98), and scene time interval (STI; OR: 0.89; 95% CI: 0.81-0.99) were valuable for predicting the neurological outcome. CONCLUSIONS Direct ambulance delivery to intensive heart hospitals that had 24/7 PCI availability was associated with a higher probability of surviving until discharge in OHCA patients with shockable rhythms. Similarly, a witnessed collapse was correlated with being discharged alive from hospital and recovering with good cerebral performance. In addition, longer response time and scene time interval indicated poorer survival and neurological outcome.

Hospital characteristics and favourable neurological outcome among patients with out-of-hospital cardiac arrest in Osaka, Japan. Resuscitation 2016; 110:146-153. [PMID: 27893969 DOI: 10.1016/j.resuscitation.2016.11.009] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2016] [Revised: 10/27/2016] [Accepted: 11/13/2016] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To assess the association between favourable neurological outcome and hospital characteristics such as hospital volume and number of critical care centres (CCMCs) after out-of-hospital cardiac arrest (OHCA). METHODS This retrospective, population-based observational study conducted in Osaka Prefecture, Japan included adult patients with OHCA, aged ≥18 years who were transported to acute care hospitals between January 2005 and December 2012. We divided acute care hospitals into CCMCs or non-CCMCs, the latter of which were divided into the following three groups according to the annual average number of transported OHCA cases: low-volume (≤10 cases), middle-volume (11-39 cases), and high-volume (≥40 cases) groups. Random effects logistic regression models, with hospital treated as a random effect, were used to assess factors potentially associated with a favourable neurological outcome. RESULTS A total of 44,474 patients were eligible. The proportions of favourable neurological outcome from OHCA were 0.9% (31/3559) in the low-volume group, 1.2% (106/9171) in the middle-volume group, 1.6% (222/14,007) in the high-volume group, and 4.3% (766/17,737) in the CCMC group (P<0.001). In the multivariable analysis, transport to CCMCs was significantly associated with favourable neurological outcome, compared with transport to non-CCMCs (adjusted odds ratio 1.63; 95% confidence interval, 1.60-1.66). Among the non-CCMC group, there was no significant relationship between hospital volume and favourable neurological outcome. CONCLUSIONS In this population, transport of OHCA patients to CCMCs led to significantly higher one-month survival rates with favourable neurological outcome from OHCA, whereas no significant association was noted among the hospitals with different volumes.

Acad Emerg Med 2016; 23:905-9. [PMID: 27027857 DOI: 10.1111/acem.12978] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 03/21/2016] [Accepted: 03/28/2016] [Indexed: 01/15/2023]
Abstract
OBJECTIVE To test whether primary emergency medical services (EMS) transport to hospitals with certain characteristics (24/7 percutaneous coronary intervention [PCI] availability, trauma center status, large [>24 bed] intensive care unit [ICU]) versus hospitals without those characteristics is associated with improved hospital survival after out-of-hospital cardiac arrest (OHCA). METHODS This is an analysis of a prospectively collected EMS database, which archives patients with OHCA treated by a single large metropolitan EMS system. The database contains Utstein data, EMS transport data, and survival to hospital discharge. EMS providers uniformly apply advanced cardiac life support protocols to OHCA patients in the field. Patients with return of spontaneous circulation (ROSC) are transported to one of 10 hospitals in the area. If ROSC is not achieved within 30 minutes, efforts are terminated and the patient is not transported. We used multivariate logistic regression to test if receiving hospital characteristics were independently associated with survival among those transported after ROSC. We excluded patients not transported to a hospital and patients with incomplete outcome data. RESULTS Between January 2011 and December 2014, a total of 1,188 OHCA patients were resuscitated in the field and transported to an area hospital. After patients with missing data were excluded, 1,024 patients were included in the analysis. The mean (±SD) age was 61.1 (±17.0) years, and 57.7% were male. Of transported patients, 76% were taken to 24/7 PCI centers, 46% were taken to trauma centers, and 37% were taken to hospitals with large ICUs. There was considerable overlap in these hospital characteristics. A multivariate logistic regression model including age, sex, shockable rhythm, EMS time to scene, and dispatch complaint of cardiac arrest found that none of the hospital characteristics were independently associated with increased survival to discharge. The odds ratios (95% confidence intervals) for survival were as follows: PCI center, 1.28 (0.80 to 2.04); trauma center, 1.44 (0.73 to 2.85); and large ICU, 1.39 (0.69 to 2.80). CONCLUSIONS After adjusting for patient demographic data, we found no significant independent association between receiving hospital characteristics and survival to discharge among OHCA patients transported after ROSC by a single EMS agency.
