Abstract
Sparse data exist on sex-related differences in extracorporeal cardiopulmonary resuscitation (ECPR) for refractory cardiac arrest (rCA). We explored the role of sex on the utilization and outcomes of ECPR for rCA by retrospective analysis of the Extracorporeal Life Support Organization (ELSO) International Registry. The primary outcome was in-hospital mortality. Exploratory outcomes were discharge disposition and occurrence of any specific extracorporeal membrane oxygenation (ECMO) complications. From 1992 to 2020, a total of 7,460 adults with ECPR were identified: 30.5% women; 69.5% men; 55.9% Whites, 23.7% Asians, 8.9% Blacks, and 3.8% Hispanics. Women's age was 50.4 ± 16.9 years (mean ± standard deviation) and men's 54.7 ± 14.1 (p < 0.001). Ischemic heart disease occurred in 14.6% women vs. 18.5% men (p < 0.001). Overall, 28.5% survived at discharge, 30% women vs. 27.8% men (p = 0.138). In the adjusted analysis, sex was not associated with in-hospital mortality (odds ratio [OR] = 0.93 [confidence interval {CI} = 0.80-1.08]; p = 0.374). Female sex was associated with decreased odds of neurologic, cardiovascular, and renal complications. Despite being younger and having fewer complications during ECMO, women had in-hospital mortality similar to men. Whether these findings are driven by biologic factors or disparities in health care warrants further investigation.

Developing a responsive model to societal needs in medical education. BMC MEDICAL EDUCATION 2024; 24:370. [PMID: 38575947 PMCID: PMC10996077 DOI: 10.1186/s12909-024-05355-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 03/27/2024] [Indexed: 04/06/2024]
Abstract
BACKGROUND Responsiveness is relevant in the context of treatment and the provision of medical services. However, if we delve deeper into the subject, we must establish and develop responsiveness within the medical sciences education system. This study aims to identify the dimensions that significantly impact responsiveness in the medical education system based on a comprehensive review and expert opinions in healthcare. METHODS The present research is descriptive-analytical in terms of its objective and follows a mixed-method approach. This study was conducted in three stages. Initially, we utilized relevant keywords related to education in databases, such as Web of Science, Scopus, ScienceDirect, OVID, CINHAL, EBSCO, Google Scholar, Iranmedex, SID, and Irandoc. Subsequently, in the expert panel session stage, the factors influencing responsiveness were identified in the comprehensive review stage, and with this thematic background, they were conceptualized. Finally, the Confirmatory Factor Analysis (CFA) technique was employed to coherently examine the relationships between variables and present the final model. RESULTS We obtained 32 articles from the comprehensive review of studies. Four components in planning, implementation, monitoring and evaluation, and intersectoral cooperation were identified based on expert panel opinions. Based on the standardized coefficients, the components of research-based educational planning, community-oriented education evaluation indicators, and utilization of modern educational methods are statistically significant. CONCLUSION The establishment and development of responsiveness in the medical sciences education system involve training specialized and responsive human resources through innovative educational methods that have sufficient familiarity with the multidimensional concepts of health and how to achieve them. This approach allows for practical and responsible steps toward training competent and committed physicians in line with the needs of society. On the other hand, responsiveness in the medical sciences education system can be improved by enhancing research-based educational planning and developing community-oriented evaluation indicators that can assess the number of revised educational programs based on societal needs. Therefore, understanding the critical elements in revising medical education programs, which play the most significant role in addressing societal needs and responding to changing disease patterns and new health priorities, is both a necessity and an important priority.

Abstract
Cardiac arrest is common and deadly, affecting up to 700 000 people in the United States annually. Advanced cardiac life support measures are commonly used to improve outcomes. This "2023 American Heart Association Focused Update on Adult Advanced Cardiovascular Life Support" summarizes the most recent published evidence for and recommendations on the use of medications, temperature management, percutaneous coronary angiography, extracorporeal cardiopulmonary resuscitation, and seizure management in this population. We discuss the lack of data in recent cardiac arrest literature that limits our ability to evaluate diversity, equity, and inclusion in this population. Last, we consider how the cardiac arrest population may make up an important pool of organ donors for those awaiting organ transplantation.

Mediators of the Association Between Socioeconomic Status and Survival After Out-of-Hospital Cardiac Arrest: A Systematic Review. Can J Cardiol 2024:S0828-282X(24)00009-6. [PMID: 38211888 DOI: 10.1016/j.cjca.2024.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/21/2023] [Accepted: 01/01/2024] [Indexed: 01/13/2024] Open
Abstract
Low socioeconomic status (SES) is associated with poor outcomes after out-of-hospital cardiac arrest (OHCA). Patient characteristics, care processes, and other contextual factors may mediate the association between SES and survival after OHCA. Interventions that target these mediating factors may reduce disparities in OHCA outcomes across the socioeconomic spectrum. This systematic review identified and quantified mediators of the SES-survival after OHCA association. Electronic databases (MEDLINE, Embase, PubMed, Web of Science) and grey literature sources were searched from inception to July or August 2023. Observational studies of OHCA patients that conducted mediation analyses to evaluate potential mediators of the association between SES (defined by income, education, occupation, or a composite index) and survival outcomes were included. A total of 10 studies were included in this review. Income (n = 9), education (n = 4), occupation (n = 1), and composite indices (n = 1) were used to define SES. The proportion of OHCA cases that had bystander involvement, presented with an initial shockable rhythm, and survived to hospital discharge or 30 days increased with higher SES. Common mediators of the SES-survival association that were evaluated included initial rhythm (n = 6), emergency medical services response time (n = 5), and bystander cardiopulmonary resuscitation (n = 4). Initial rhythm was the most important mediator of this association, with a median percent excess risk explained of 37.4% (range 28.6%-40.0%; n = 5; 1 study reported no mediation) and mediation proportion of 41.8% (n = 1). To mitigate socioeconomic disparities in outcomes after OHCA, interventions should target potentially modifiable mediators, such as initial rhythm, which may involve improving bystander awareness of OHCA and the need for prompt resuscitation.

In-hospital outcomes by insurance type among patients undergoing percutaneous coronary interventions for acute myocardial infarction in New South Wales public hospitals. Int J Equity Health 2023; 22:226. [PMID: 37872627 PMCID: PMC10594777 DOI: 10.1186/s12939-023-02030-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 10/03/2023] [Indexed: 10/25/2023] Open
Abstract
BACKGROUND International evidence suggests patients receiving cardiac interventions experience differential outcomes by their insurance status. We investigated outcomes of in-hospital care according to insurance status among patients admitted in public hospitals with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). METHODS We conducted a cohort study within the Australian universal health care system with supplemental private insurance. Using linked hospital and mortality data, we included patients aged 18 + years admitted to New South Wales public hospitals with AMI and undergoing their first PCI from 2017-2020. We measured hospital-acquired complications (HACs), length of stay (LOS) and in-hospital mortality among propensity score-matched private and publicly funded patients. Matching was based on socio-demographic, clinical, admission and hospital-related factors. RESULTS Of 18,237 inpatients, 30.0% were privately funded. In the propensity-matched cohort (n = 10,630), private patients had lower rates of in-hospital mortality than public patients (odds ratio: 0.59, 95% CI: 0.45-0.77; approximately 11 deaths avoided per 1,000 people undergoing PCI procedures). Mortality differences were mostly driven by STEMI patients and those from major cities. There were no significant differences in rates of HACs or average LOS in private, compared to public, patients. CONCLUSION Our findings suggest patients undergoing PCI in Australian public hospitals with private health insurance experience lower in-hospital mortality compared with their publicly insured counterparts, but in-hospital complications are not related to patient health insurance status. Our findings are likely due to unmeasured confounding of broader patient selection, socioeconomic differences and pathways of care (e.g. access to emergency and ambulatory care; delays in treatment) that should be investigated to improve equity in health outcomes.

Association of Socioeconomic Status With Long-Term Outcome in Survivors After Out-of-Hospital Cardiac Arrest: Nationwide Population-Based Longitudinal Study. JMIR Public Health Surveill 2023; 9:e47156. [PMID: 37432716 PMCID: PMC10369165 DOI: 10.2196/47156] [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: 03/09/2023] [Revised: 04/12/2023] [Accepted: 06/14/2023] [Indexed: 07/12/2023] Open
Abstract
BACKGROUND Out-of-hospital cardiac arrest (OHCA) is a major public health problem and a leading cause of death worldwide. Previous studies have focused on improving the survival of people who have had OHCA by analyzing short-term survival outcomes, such as the return of spontaneous circulation, 30-day survival, and survival to discharge. Research has been conducted on prehospital prognostic factors to improve the survival of patients with OHCA, among which the association between socioeconomic status (SES) and survival has been reported. SES could affect bystander cardiopulmonary resuscitation rates and whether OHCA is witnessed, and low cardiopulmonary resuscitation education rates are associated with low SES. It has been reported that areas with high SES have shorter hospital transfer times and more public defibrillators per person. Previous studies have shown the impact of SES disparities on the short-term survival of patients with OHCA. However, understanding the impact of SES on the long-term prognosis of OHCA survivors remains limited. As long-term outcomes are more indicative of a patient's ongoing health care needs and the burden on public health than short-term outcomes, understanding the long-term prognosis of OHCA survivors is important. OBJECTIVE This study aimed to identify whether SES influenced the long-term outcomes of OHCA. METHODS Using health claims data obtained from the National Health Insurance (NHI) service in Korea, we included OHCA survivors who were hospitalized between January 2005 and December 2015. The patients were divided into 2 groups: NHI and Medical Aid (MA) groups, with the MA group defined as having a low SES. Cumulative mortality was estimated using the Kaplan-Meier method, and a Cox proportional hazards model was used to evaluate the impact of SES on long-term mortality. A subgroup analysis was performed based on whether cardiac procedures were performed. RESULTS We followed 4873 OHCA survivors for up to 14 years (median of 3.3 years). The Kaplan-Meier survival curve showed that the MA group had a significantly decreased long-term survival rate compared to the NHI group. With an adjusted hazard ratio (aHR) of 1.52 (95% CI 1.35-1.72), low SES was associated with increased long-term mortality. The overall mortality rate of the patients who underwent cardiac procedures in the MA group was significantly higher than that of the NHI group (aHR 1.72, 95% CI 1.05-2.82). The overall mortality rate of patients without cardiac procedures was also increased in the MA group compared to the NHI group (aHR 1.39, 95% CI 1.23-1.58). CONCLUSIONS OHCA survivors with low SES had an increased risk of poor long-term outcomes compared with those with higher SES. OHCA survivors with low SES who have undergone cardiac procedures need considerable care for long-term survival.

Abstract
This review highlights the current evidence on racial, ethnic, and socioeconomic disparities in cardiac arrest outcomes within the United States. Several studies demonstrate that patients from Black, Hispanic, or lower socioeconomic status backgrounds suffer the most from disparities at multiple levels of the resuscitation pathway, including in the provision of bystander cardiopulmonary resuscitation, defibrillator usage, and postresuscitation therapies. These gaps in care may altogether lead to lower survival rates and worse neurological outcomes for these patients. A multisystem, culturally sensitive approach to improving cardiac arrest outcomes is suggested in this article.

Abstract
Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) represents an increasingly used method for circulatory support. Despite the ongoing research, survival following VA-ECMO therapy remains low. Sex-related differences might impact the outcome of therapeutic measures. We aimed to compare all-cause mortality among female and male patients who underwent VA-ECMO as a bridge to recovery investigating sex-related differences. From January 2015 until August 2020, 87 patients were supported by VA-ECMO as a part of our out-of-center mobile ECMO program. In order to analyze sex-associated differences in early clinical outcomes, patients were divided into two sex categories: men (n = 62) and women (n = 25). All relevant data (in-hospital mortality, ICU and hospital stay, renal failure requiring dialysis, lung failure, bleeding, stroke and septic shock) were analyzed retrospectively after the extraction from our institutional database. Mean age of the study population was 53 ± 14 years. Mean EuroSCORE II predicted mortality was 6.5 ± 3.7. In-hospital mortality rate was not significantly lower in the female group (58.3%) vs. the male group (71.2%), p = 0.190. The mean length of ICU and hospital stay was 9 ± 11 in the male group vs. 10 ± 13 in the female group, p = 0.901, and 10 ± 12 (male group) vs. 11 ± 13 (female group), p = 0.909, respectively. Renal failure requiring hemodialysis (36.2% (males) vs. 28.6% (females), p = 0.187) was comparable between both groups. Respiratory failure was diagnosed in 31 (56.4%) male vs. 8 (34.8%) female patients, p = 0.068, while 16 (28.6%) male vs. 3 (13.0%) female patients (p = 0.118) suffered from septic shock. Based on our data, there were no sex-specific outcome discrepancies in patients treated with mobile VA-ECMO implantation.

Abstract
Background There are limited data on the sex-based differences in the outcome of readmission after cardiac arrest. Methods and Results Using the Nationwide Readmissions Database, we analyzed patients hospitalized with cardiac arrest between 2010 and 2015. Based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, we identified comorbidities, therapeutic interventions, and outcomes. Multivariable logistic regression was performed to assess the independent association between sex and outcomes. Of 835 894 patients, 44.4% (n=371 455) were women, of whom 80.7% presented with pulseless electrical activity (PEA)/asystole. Women primarily presented with PEA/asystole (80.7% versus 72.4%) and had a greater comorbidity burden than men, as assessed using the Elixhauser Comorbidity Score. Thirty-day readmission rates were higher in women than men in both PEA/asystole (20.8% versus 19.6%) and ventricular tachycardia/ventricular fibrillation arrests (19.4% versus 17.1%). Among ventricular tachycardia/ventricular fibrillation arrest survivors, women were more likely than men to be readmitted because of noncardiac causes, predominantly infectious, respiratory, and gastrointestinal illnesses. Among PEA/asystole survivors, women were at higher risk for all-cause (adjusted odds ratio [aOR], 1.07; [95% CI, 1.03-1.11]), cardiac-cause (aOR, 1.15; [95% CI, 1.06-1.25]), and noncardiac-cause (aOR, 1.13; [95% CI, 1.04-1.22]) readmission. During the index hospitalization, women were less likely than men to receive therapeutic procedures, including coronary angiography and targeted therapeutic management. While the crude case fatality rate was higher in women, in both ventricular tachycardia/ventricular fibrillation (51.8% versus 47.4%) and PEA/asystole (69.3% versus 68.5%) arrests, sex was not independently associated with increased crude case fatality after adjusting for differences in baseline characteristics. Conclusions Women are at increased risk of readmission following cardiac arrest, independent of comorbidities and therapeutic interventions.

Abstract
Introduction: Achieving equity in health care remains a challenge for health care systems worldwide and marked inequities in access and quality of care persist. Identifying health care equity indicators is an important first step in integrating the concept of equity into assessments of health care system performance, particularly in emergency care. Methods: We conducted a systematic review of administrative data-derived health care equity indicators and their association with socioeconomic determinants of health (SEDH) in emergency care settings. Following PRISMA-Equity reporting guidelines, Ovid MEDLINE, EMBASE, PubMed, and Web of Science were searched for relevant studies. The outcomes of interest were indicators of health care equity and the associated SEDH they examine. Results: Among 29 studies identified, 14 equity indicators were identified and grouped into four categories that reflect the patient emergency care pathway. Total emergency department (ED) visits and ambulatory care-sensitive condition-related ED visits were the two most frequently used equity indicators. The studies analyzed equity based on seven SEDH: social deprivation, income, education level, social class, insurance coverage, health literacy, and financial and nonfinancial barriers. Despite some conflicting results, all identified SEDH are associated with inequalities in access to and use of emergency care. Conclusion: The use of administrative data-derived indicators in combination with identified SEDH could improve the measurement of health care equity in emergency care settings across health care systems worldwide. Using a combination of indicators is likely to lead to a more comprehensive, well-rounded measurement of health care equity than using any one indicator in isolation. Although studies analyzed focused on emergency care settings, it seems possible to extrapolate these indicators to measure equity in other areas of the health care system. Further studies elucidating root causes of health inequities in and outside the health care system are needed.

Abstract
OBJECTIVE Elucidate how physicians formulate a neurological prognosis after cardiac arrest and compare differences between experts and general providers. METHODS We performed semi-structured interviews with experts in post-arrest care and general physicians. We created an initial model and interview guide based on professional society guidelines. Two authors independently coded interviews based on this initial model, then identified new topics not included in it. To describe individual physicians' cognitive approach to prognostication, we created a graphical representation. We summarized these individual "mental models" into a single overall model, as well as two models stratified by expertise. RESULTS We performed 36 interviews (17 experts and 19 generalists), most of whom practice in Europe (23) or North America (12). Participants described their approach to prognosis formulation as complex and iterative, with sequential and repeated data acquisition, interpretation, and prognosis formulation. Eventually, this cycle results in a final prognosis and treatment recommendation. Commonly mentioned factors were diagnostic test performance, time from arrest, patient characteristics. Participants also discussed factors rarely discussed in prognostication research including physician and hospital characteristics. We found no substantial differences between experts and general physicians. CONCLUSION Physicians' cognitive approach to neurologic prognostication is complex and influenced by many factors, including some rarely considered in current research. Understanding these processes better could inform interventions designed to aid physicians in prognostication.

Abstract
Introduction Social disparities in out-of-hospital cardiac arrest (OHCA) outcomes are preventable, costly, and unjust. We sought to perform the first large artificial intelligence- (AI-) guided statistical and geographic information system (GIS) analysis of a multiyear and multisite cohort for OHCA outcomes (incidence and poor neurological disposition). Method We conducted a retrospective cohort analysis of a prospectively collected multicenter dataset of adult patients who sequentially presented to Houston metro area hospitals from 01/01/07-01/01/16. Then AI-based machine learning (backward propagation neural network) augmented multivariable regression and GIS heat mapping were performed. Results Of 3,952 OHCA patients across 38 hospitals, African Americans were the most likely to suffer OHCA despite representing a significantly lower percentage of the population (42.6 versus 22.8%; p < 0.001). Compared to Caucasians, they were significantly more likely to have poor neurological disposition (OR 2.21, 95%CI 1.25–3.92; p=0.006) and be discharged to a facility instead of home (OR 1.39, 95%CI 1.05–1.85; p=0.023). Compared to the safety net hospital system primarily serving poorer African Americans, the university hospital serving primarily higher income commercially and Medicare insured patients had the lowest odds of death (OR 0.45, p < 0.001). Each additional $10,000 above median household income was associated with a decrease in the total number of cardiac arrests per zip code by 2.86 (95%CI -4.26- -1.46; p < 0.001); zip codes with a median income above $54,600 versus the federal poverty level had 14.62 fewer arrests (p < 0.001). GIS maps showed convergence of the greater density of poor neurologic outcome cases and greater density of poorer African American residences. Conclusion This large, longitudinal AI-guided analysis statistically and geographically identifies racial and socioeconomic disparities in OHCA outcomes in a way that may allow targeted medical and public health coordinated efforts to improve clinical, cost, and social equity outcomes.

Abstract
Background Variation exists in outcomes following out-of-hospital cardiac arrest, but whether racial and ethnic disparities exist in postarrest provision of targeted temperature management (TTM) is unknown. Methods and Results We performed a retrospective analysis of a prospectively collected cohort of patients who survived to admission following out-of-hospital cardiac arrest from the Cardiac Arrest Registry to Enhance Survival, whose catchment area represents ≈50% of the United States from 2013 to 2019. Our primary exposure was race or ethnicity and primary outcome was utilization of TTM. We built a mixed-effects model with both state of arrest and admitting hospital modeled as random intercepts to account for clustering. Among 96 695 patients (24.6% Black patients, 8.0% Hispanic/Latino patients, and 63.4% White patients), a smaller percentage of Hispanic/Latino patients received TTM than Black or White patients (37.5% versus 45.0% versus 43.3%, P<0.001) following out-of-hospital cardiac arrest. In the mixed-effects model, Black patients (odds ratio [OR], 1.153 [95% CI, 1.102-1.207], P<0.001) and Hispanic/Latino patients (OR, 1.086 [95% CI, 1.017-1.159], P<0.001) were slightly more likely to receive TTM compared with White patients, perhaps because of worse neurological status on admission. We did find community- level disparity because Hispanic/Latino-serving hospitals (defined as the top decile of hospitals that cared for the highest proportion of Hispanic/Latino patients) provided less TTM (OR, 0.587 [95% CI, 0.474-0.742], P<0.001). Conclusions Reassuringly, we did not find evidence of intrahospital or interpersonal racial or ethnic disparity in the provision of TTM. However, we did find interhospital, community-level disparity. Hispanic/Latino-serving hospitals provided less guideline-recommended TTM after out-of-hospital cardiac arrest.

Women receive less targeted temperature management than men following out-of-hospital cardiac arrest due to early care limitations - A study from the CARES Investigators. Resuscitation 2021; 169:97-104. [PMID: 34756958 DOI: 10.1016/j.resuscitation.2021.10.036] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 09/28/2021] [Accepted: 10/01/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Women experience worse neurological outcomes following out-of-hospital cardiac arrest (OHCA). It is unknown whether sex disparities exist in the use of targeted temperature management (TTM), a standard of care treatment to improve neurological outcomes. METHODS We performed a retrospective study of prospectively collected patients who survived to hospital admission following OHCA from the Cardiac Arrest Registry to Enhance Survival from 2013 through 2019. We compared receipt of TTM by sex in a mixed-effects model adjusted for patient, arrest, neighborhood, and hospital factors, with the admitting hospital modeled as a random intercept. RESULTS Among 123,419 patients, women had lower rates of shockable rhythms (24.4 % vs. 39.2%, P < .001) and lower rates of presumed cardiac aetiologies for arrest (74.3% vs. 81.1%, P < .001). Despite receiving a similar rate of TTM in the field (12.1% vs. 12.6%, P = .02), women received less TTM than men upon admission to the hospital (41.6% vs. 46.4%, P < .001). In an adjusted mixed-effects model, women were less likely than men to receive TTM (Odds Ratio 0.91, 95% Confidence Interval 0.89 to 0.94). Among the 27,729 patients with data indicating the reason for not using TTM, a higher percentage of women did not receive TTM due to Do-Not-Resuscitate orders/family requests (15.1% vs. 11.4%, p < .001) and non-shockable rhythms (11.1% vs. 8.4%, p < .001). CONCLUSIONS We found that women received less TTM than men, likely due to early care limitations and a preponderance of non-shockable rhythms.

Do Women Have a Higher Mortality Risk Than Men following ICU Admission after Out-of-Hospital Cardiac Arrest? A Retrospective Cohort Analysis. J Clin Med 2021; 10:jcm10184286. [PMID: 34575397 PMCID: PMC8470772 DOI: 10.3390/jcm10184286] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 09/14/2021] [Accepted: 09/17/2021] [Indexed: 11/29/2022] Open
Abstract
Purpose: previous studies showed that women have a higher mortality risk than men after out-of-hospital cardiac arrest (OHCA). This sex difference may disappear after adjustment for cardiac arrest characteristics. Most studies also included patients who were not admitted to the intensive care unit (ICU). We analyzed whether sex impacts the mortality of ICU-admitted OHCA patients. Methods: a retrospective cohort analysis of 1240 OHCA patients admitted to the ICU (310 women, 25%, AgeMedian 64.0 (IQR 53.8–73.0)) at an academic hospital in the Netherlands between 1 January 2007 and 31 December 2018. The primary outcome was 90-day mortality; the secondary outcome was a favorable cerebral performance category (CPC) score at ICU discharge and ICU length of stay (ICU LOS). Results: we found no association between sex and 90-day mortality (hazard ratio (HR) 0.867; 95% confidence interval (95% CI) 0.678–1.108) after adjusting for relevant cardiac arrest characteristics. Similarly, we found no difference for favorable CPC score (OR 1.117; 95% CI 0.777–1.608) or ICU LOS between sexes (Beta 0.428; 95% CI −0.442 to 1.298). Conclusions: after adjusting for cardiac arrest characteristics, we found no difference between women and men with respect to 90-day mortality, ICU LOS, and CPC score.

Treatment and survival following in-hospital cardiac arrest: does patient ethnicity matter? Eur J Cardiovasc Nurs 2021; 21:341-347. [PMID: 34524428 DOI: 10.1093/eurjcn/zvab079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 06/08/2021] [Accepted: 08/20/2021] [Indexed: 11/13/2022]
Abstract
AIMS Previous research on racial/ethnic disparities in relation to cardiac arrest has mainly focused on black vs. white disparities in the USA. The great majority of these studies concerns out-of-hospital cardiac arrest (OHCA). The current nationwide registry study aims to explore whether there are ethnic differences in treatment and survival following in-hospital cardiac arrest (IHCA), examining possible disparities towards Middle Eastern and African minorities in a European context. METHODS AND RESULTS In this retrospective registry study, 24 217 patients from the IHCA part of the Swedish Registry of Cardiopulmonary Resuscitation were included. Data on patient ethnicity were obtained from Statistics Sweden. Regression analysis was performed to assess the impact of ethnicity on cardiopulmonary resuscitation (CPR) delay, CPR duration, survival immediately after CPR, and the medical team's reported satisfaction with the treatment. Middle Eastern and African patients were not treated significantly different compared to Nordic patients when controlling for hospital, year, age, sex, socioeconomic status, comorbidity, aetiology, and initial heart rhythm. Interestingly, we find that Middle Eastern patients were more likely to survive than Nordic patients (odds ratio = 1.52). CONCLUSION Overall, hospital staff do not appear to treat IHCA patients differently based on their ethnicity. Nevertheless, Middle Eastern patients are more likely to survive IHCA.

Abstract
OBJECTIVE To determine the preoperative risk factors most predictive of prolonged length of stay (LOS) or admission to a skilled nursing facility (SNF) or inpatient rehabilitation center (IPR) after free flap reconstruction of the head and neck. STUDY DESIGN Retrospective cohort study. SETTING Tertiary academic medical center. METHODS Retrospective review of 1008 patients who underwent tumor resection and free flap reconstruction of the head and neck at a tertiary referral center from 2002 to 2019. RESULTS Of 1008 patients (65.7% male; mean age of 61.4 years, SD 14.0 years), 161 (15.6%) were discharged to SNF/IPR, and the median LOS was 7 days. In multiple linear regression analysis, Charlson Comorbidity Index (CCI; P < .001), American Society of Anesthesiologists (ASA) classification (P = .021), female gender (P = .023), and inability to tolerate oral diet preoperatively (P = .006) were statistically significantly related to increased LOS, whereas age, body mass index (BMI), modified frailty index (MFI), a history of prior radiation or chemotherapy, and home oxygen use were not. Multiple logistic regression analysis demonstrated that CCI (odds ratio [OR] = 1.119, confidence interval [CI] 1.023-1.223), age (OR = 1.082, CI 1.056-1.108), and BMI <19.0 (OR = 2.141, CI 1.159-3.807) were the only variables statistically significantly related to posthospital placement in an SNF or IPR. CONCLUSION Common tools for assessing frailty and need for additional care may be inadequate in a head and neck reconstructive population. CCI appears to be the best of the aggregate metrics assessed, with significant relationships to both LOS and placement in SNF/IPR.

Influence of sex on survival, neurologic outcomes, and neurodiagnostic testing after out-of-hospital cardiac arrest. Resuscitation 2021; 167:66-75. [PMID: 34363853 DOI: 10.1016/j.resuscitation.2021.07.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 07/18/2021] [Accepted: 07/22/2021] [Indexed: 10/20/2022]
Abstract
AIM Previous studies evaluating the relationship between sex and post-resuscitation care and outcomes following out-of-hospital cardiac arrest (OHCA) are conflicting. We investigated the association between sex and outcomes as well as neurodiagnostic testing in a prospective multicenter international registry of patients admitted to intensive care units following OHCA. METHODS OHCA survivors enrolled in the International Cardiac Arrest Registry (INTCAR) from 2012-2017 were included. We assessed the independent association between sex and survival to hospital discharge, good neurologic outcome (Cerebral Performance Category 1 or 2), neurodiagnostic testing, and withdrawal of life-sustaining therapy (WLST). RESULTS Of 2,407 eligible patients, 809 (33.6%) were women. Baseline characteristics differed by sex, with less bystander CPR and initial shockable rhythms among women. Women were less likely to survive to hospital discharge, however significance abated following adjusted analysis (30.1% vs 42.7%, adjusted OR 0.85, 95% CI 0.67-1.08). Women were less likely to have good neurologic outcome at discharge (21.4% vs 34.0%, adjusted OR 0.74, 95% CI 0.57-0.96) and at six months post-arrest (16.7% vs 29.4%, adjusted OR 0.73, 95% CI 0.54-0.98) that persisted after adjustment. Neuroimaging (75.5% vs 74.3%, p=0.54) and other neurophysiologic testing (78.8% vs 78.6%, p=0.91) was similar across sex. Women were more likely to undergo WLST (55.6% vs 42.8%, adjusted OR 1.35, 95% CI 1.09-1.66). CONCLUSIONS Women with cardiac arrest have lower odds of good neurologic outcomes and higher odds of WLST, despite comparable rates of neurodiagnostic testing and after controlling for baseline differences in clinical characteristics and cardiac arrest features.

Abstract
Objectives There do not appear to be many studies which have examined the socio-economic burden and medical factors influencing the mortality and hospital costs incurred by patients with cardiac arrest in South Korea. We analyzed the differences in characteristics, medical factors, mortality, and costs between patients with national health insurance and those on a medical aid program. Methods We selected patients (≥20 years old) who experienced their first episode of cardiac arrest from 2004 to 2015 using data from the National Health Insurance Service database. We analyzed demographic characteristics, insurance type, urbanization of residential area, comorbidities, treatments, hospital costs, and mortality within 30 days and one year for each group. A multiple regression analysis was used to identify an association between insurance type and outcomes. Results Among the 487,442 patients with cardiac arrest, the medical aid group (13.3% of the total) had a higher proportion of females, rural residents, and patients treated in low-level hospitals. The patients in the medical aid group also reported a higher rate of non-shockable conditions; a high Charlson Comorbidity Index; and pre-existing comorbidities, such as hypertension, diabetes mellitus, and renal failure with a lower rate of providing a coronary angiography. The national health insurance group reported a lower one-year mortality rate (91.2%), compared to the medical aid group (94%), and a negative association with one-year mortality (Adjusted OR 0.74, 95% CI 0.71–0.76). While there was no significant difference in short-term costs between the two groups, the medical aid group reported lower long-term costs, despite a higher rate of readmission. Conclusions Medical aid coverage was an associated factor for one-year mortality, and may be the result of an insufficient delivery of long-term services as reflected by the lower long-term costs and higher readmission rates. There were differences of characteristics, comorbidities, medical and hospital factors and treatments in two groups. These differences in medical and hospital factors may display discrepancies by type of insurance in the delivery of services, especially in chronic healthcare services.

Abstract
BACKGROUND Curative-intent treatment of acute myeloid leukaemia (AML) can lead to multiple chronic medical conditions ('late effects'). Little is known about the burden of late effects in adolescent and young adult (AYA, 15-39 years) survivors of AML. We aimed to estimate the cumulative incidence and investigate the main predictors of late effects among these patients. METHODS During 1996-2012, 1168 eligible AYAs with AML who survived ≥2 years after diagnosis were identified in the California Cancer Registry. Late effects were reported from State hospital discharge data, and patients were followed through 2014. Hazard ratios and 95% confidence intervals of late effects occurrence were estimated using Cox proportional hazard models, adjusted for sociodemographic and clinical factors. RESULTS The most common late effects at 10 years after diagnosis were: endocrine (26.1%), cardiovascular (18.6%) and respiratory (6.6%), followed by neurologic (4.9%), liver/pancreatic (4.3%), renal (3.1%), avascular necrosis (2.7%) and second primary malignancies (2.4%). Of 1168 survivors, 547 (46.8%) received a haematopoietic stem cell transplant (HSCT). After multivariable adjustments, AYAs who underwent HSCT or had a non-favourable risk AML experienced ∼2-fold or higher increased likelihood of all late effects. Additionally, AYAs of Hispanic, Black or Asian/Pacific Islander (vs non-Hispanic White) race/ethnicity and those who resided in lower socio-economic neighbourhoods were at higher risk of numerous late effects. CONCLUSIONS Our findings underscore the need for long-term surveillance for the prevention, early detection and treatment of late effects, and can inform the development of AYA-focused consensus-based guidelines that will ultimately improve the quality of life and survival of these young vulnerable patients.

Higher 1-year mortality in women admitted to intensive care units after cardiac arrest: A nationwide overview from the Netherlands between 2010 and 2018. J Crit Care 2021; 64:176-183. [PMID: 33962218 DOI: 10.1016/j.jcrc.2021.04.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 03/25/2021] [Accepted: 04/12/2021] [Indexed: 11/26/2022]
Abstract
PURPOSE We study sex differences in 1-year mortality of out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) patients admitted to the intensive care unit (ICU). DATA A retrospective cohort analysis of OHCA and IHCA patients registered in the NICE registry in the Netherlands. The primary and secondary outcomes were 1-year and hospital mortality, respectively. RESULTS We included 19,440 OHCA patients (5977 women, 30.7%) and 13,461 IHCA patients (4889 women, 36.3%). For OHCA, 1-year mortality was 63.9% in women and 52.6% in men (Hazard Ratio [HR] 1.28, 95% Confidence Interval [95% CI] 1.23-1.34). For IHCA, 1-year mortality was 60.0% in women and 57.0% in men (HR 1.09, 95% CI 1.04-1.14). In OHCA, hospital mortality was 57.4% in women and 46.5% in men (Odds Ratio [OR] 1.42, 95% CI 1.33-1.52). In IHCA, hospital mortality was 52.0% in women and 48.2% in men (OR 1.11, 95% CI 1.03-1.20). CONCLUSION Women admitted to the ICU after cardiac arrest have a higher mortality rate than men. After left-truncation, we found that this sex difference persisted for OHCA. For IHCA we found that the effect of sex was mainly present in the initial phase after the cardiac arrest.

Bypassing out-of-hospital cardiac arrest patients to a regional cardiac center: Impact on hemodynamic parameters and outcomes. Am J Emerg Med 2021; 44:95-99. [PMID: 33582615 DOI: 10.1016/j.ajem.2021.01.080] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 01/25/2021] [Accepted: 01/26/2021] [Indexed: 02/04/2023] Open
Abstract
INTRODUCTION Current guidelines recommend systematic care for patients who experience out-of-hospital cardiac arrest (OHCA) and the development of cardiac arrest centers (CACs). However, data regarding prolonged transport time of these often hemodynamically unstable patients are limited. METHODS Data from a prospective OHCA registry of a regional CAC collected between 2013 and 2017, when all OHCA patients from the district were required to be transferred directly to the CAC, were analyzed. Patients were divided into two subgroups: CAC, when the CAC was the nearest hospital; and bypass, when OHCA occurred in a region of another local hospital but the subject was transferred directly to the CAC (7 hospitals in the district). Data included transport time, baseline characteristics, hemodynamic and laboratory parameters on admission (systolic blood pressure, lactate, pH, oxygen saturation, body temperature, and initial doses of vasopressors and inotropes), and final outcomes (30-day in-hospital mortality, intensive care unit stay, days on artificial ventilation, and cerebral performance capacity at 1 year). RESULTS A total of 258 subjects experienced OHCA in the study period; however, 27 were excluded due to insufficient data and 17 for secondary transfer to CAC. As such, 214 patients were analyzed, 111 in the CAC group and 103 in the bypass group. The median transport time was significantly longer for the bypass group than the CAC group (40.5 min [IQR 28.3-55.0 min] versus 20.0 min [IQR 13.0-34.0], respectively; p˂0.0001). There were no differences in 30-day in-hospital mortality, 1-year neurological outcome, or median length of mechanical ventilation. There were no differences in baseline characteristics, initial hemodynamic parameters on admission, catecholamine dosage(s). CONCLUSION Individuals who experienced OHCA and taken to a CAC incurred significantly prolonged transport times; however, hemodynamic parameters and/or outcomes were not affected. These findings shows the safety of bypassing local hospitals for a CAC.

Abstract
Extracorporeal cardiopulmonary resuscitation (eCPR) is a rapidly growing treatment strategy due to significant improvement in selected patients' survival rates. Gender-related differences might impact the outcome of therapeutic measures. Therefore, we sought to investigate patients with eCPR at our interdisciplinary extracorporeal membrane oxygenation center regarding sex-related differences with the view to potentially adjusting current selection criteria. From January 2016 to December 2019, 71 patients underwent eCPR at our institution. Data before eCPR and early outcome parameters were analyzed comparing male and female patients. The cohort analyzed consisted of 60 male (84%) and 11 female (15%) patients. Comparing both groups, male patients significantly more frequently suffered out-of-hospital cardiac arrest (68% male vs. 36% female, P = .04), whereas female patients were associated with more in-hospital cardiac arrest (32% male vs. 64% female, P = .04). Creatinine levels differed significantly (1.5 (1.1;2.1) mg/dL in male vs. 1.0 (0.7;1.5) mg/dL in female patients, P = .03). Also, several hepatic parameters showed a significant difference between the groups: aspartate aminotransferase 423 (249;804) U/L in male vs. 115 (61;408) U/L in female patients, P = .01; alanine aminotransferase 174 (102;446) U/L in male vs. 86 (36;118) U/L in female patients, P = .01). Renal failure requiring hemodialysis occurred more frequently in men than in women (P < .01). There is a significant effect of male sex regarding renal failure with subsequent continuous venovenous hemodialysis (CVVH) (R2 = 0.11, ANOVA P = .01, 95% CI = -0.79--0.079). However, in-hospital mortality was comparable between the groups (78% in male vs. 72% in female patients, P = .68). Our retrospective study showed several gender-related differences associated with different cardiac arrest scenarios. Male sex was associated with a significantly higher risk for renal failure requiring CVVH. Survival rates were comparable between the groups. Further investigations should include gender in the evaluation of risk stratification for eCPR-related complications to further improve selection criteria for this demanding therapy.

Abstract
BACKGROUND Social accountability in medical education has been defined as an obligation to direct education, research, and service activities toward the most important health concerns of communities, regions, and nations. Drawing from the results of a summit of international experts on postgraduate medical education and accreditation, we highlight the importance of local contexts in meeting societal aims and present different approaches to ensuring societal input into medical education systems around the globe. MAIN TEXT We describe four priorities for social responsiveness that postgraduate medical education needs to address in local and regional contexts: (1) optimizing the size, specialty mix, and geographic distribution of the physician workforce; (2) ensuring graduates' competence in meeting societal goals for health care, population health, and sustainability; (3) promoting a diverse physician workforce and equitable access to graduate medical education; and (4) ensuring a safe and supportive learning environment that promotes the professional development of physicians along with safe and effective patient care in settings where trainees participate in care. We relate these priorities to the values proposed by the World Health Organization for social accountability: relevance, quality, cost-effectiveness, and equity; discuss accreditation as a lever for change; and describe existing and evolving efforts to make postgraduate medical education socially responsive. CONCLUSION Achieving social responsiveness in a competency-based postgraduate medical education system requires accrediting organizations to ensure that learning emphasizes relevant competencies in postgraduate curricula and educational experiences, and that graduates possess desired attributes. At the same time, institutions sponsoring graduate medical education need to provide safe and effective patient care, along with a supportive learning and working environment.

Impact of Sex on Survival and Neurologic Outcomes in Adults With In-Hospital Cardiac Arrest. Am J Cardiol 2020; 125:309-312. [PMID: 31791546 DOI: 10.1016/j.amjcard.2019.10.039] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 10/14/2019] [Accepted: 10/16/2019] [Indexed: 12/18/2022]
Abstract
Data regarding the impact of sex on clinical outcomes in adults with in-hospital cardiac arrest (IHCA) have yielded conflicting results. We aimed to study the impact of female sex on mortality and poor neurologic outcomes in adults with IHCA. The study population included 680 consecutive patients hospitalized with IHCA who underwent ACLS-guided resuscitation from 2012 to 2018 at an academic tertiary medical center. The primary outcome of interest was in-hospital mortality. Secondary outcome of interest was favorable neurological outcome, defined as a Glasgow Outcome Score of 4 or 5. Of the 680 patients studied, 418 (61.5%) were men and 262 (38.5%) were women. Women had lower rates of coronary artery disease, previous myocardial infarction, and peripheral artery disease, and higher rates of chronic obstructive pulmonary disease and depression. Although location of cardiac arrest, initial rhythm, and duration of cardiopulmonary resuscitation were similar in both groups, women had lower rates of defibrillation. Rates of return of spontaneous circulation and receipt of targeted temperature management were similar in men and women. With respect to outcomes, women were noted to have significantly higher rates of in-hospital mortality (87.5% vs 78.0%; p = 0.001) and lower rates of favorable neurologic outcome (10.0% vs 15.8%, p = 0.030) compared with men. In multivariable analyses, female sex was independently associated with nearly two-fold higher rates of in-hospital mortality [odds ratio (OR) 1.93, 95% confidence interval (CI) 1.22-3.04, p = 0.005] and a trend toward lower rates of favorable neurologic outcome (OR 0.63, 95% CI 0.38-1.04, p = 0.071). In conclusion, in this prospective, contemporary registry of adults with IHCA, female sex was independently associated with nearly twofold higher rates of in-hospital mortality and a trend toward lower rates of favorable neurologic outcomes.

Racial Differences in the Utilization of Guideline-Recommended and Life-Sustaining Procedures During Hospitalizations for Out-of-Hospital Cardiac Arrest. J Racial Ethn Health Disparities 2019; 7:403-412. [PMID: 31845289 DOI: 10.1007/s40615-019-00668-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Revised: 11/02/2019] [Accepted: 11/05/2019] [Indexed: 01/07/2023]
Abstract
BACKGROUND Racial and ethnic minorities are at risk for disparities in quality of care after out-of-hospital cardiopulmonary arrest (OHCA). As such, we examined associations between race and ethnicity and use of guideline-recommended and life-sustaining procedures during hospitalizations for OHCA. METHODS This was a retrospective study of hospitalizations for OHCA in all acute-care, non-federal California hospitals from 2009 to 2011. Associations between the use of (1) guideline-recommended procedures (cardiac catheterization for ventricular fibrillation/tachycardia, therapeutic hypothermia), (2) life-sustaining procedures (percutaneous endoscopic gastrostomy (PEG)/tracheostomy, renal replacement therapy (RRT)), and (3) palliative care and race/ethnicity were examined using hierarchical logistic regression analysis. RESULTS Among 51,198 hospitalizations for OHCA, unadjusted rates of cardiac catheterization were 34.9% in Whites, 19.8% in Blacks, 27.2% in Hispanics, and 30.9% in Asians (P < 0.01). Rates of therapeutic hypothermia were 2.3% in Whites, 1.1% in Blacks, 1.3% in Hispanics, and 1.9% in Asians (P < 0.01). Rates of PEG/tracheostomy and RRT were 2.2% and 9.8% in Whites, 5.7% and 19.9% in Blacks, 4.2% and 19.9% in Hispanics, and 3.4% and 18.2% in Asians, respectively (P < 0.01). Rates of palliative care were 14.8% in Whites, 9.6% in Blacks, 10.1% in Hispanics, and 14.3% in Asians (P < 0.01). Differences in utilization of procedures persisted after adjustment for patient and hospital-related factors. CONCLUSION Racial and ethnic minorities are less likely to receive guideline-recommended interventions and palliative care, and more likely to receive life-sustaining treatments following OHCA. These findings suggest that significant disparities exist in medical care after OHCA.

Do Out-of-Hospital Cardiac Arrest Patients Have Increased Chances of Survival When Transported to a Cardiac Resuscitation Center? J Am Heart Assoc 2019; 7:e011079.

Abstract
Background Patients suffering from an out‐of‐hospital cardiac arrest are often transported to the closest hospital. Although it has been suggested that these patients be transported to cardiac resuscitation centers, few jurisdictions have acted on this recommendation. To better evaluate the evidence on this subject, a systematic review and meta‐analysis of the currently available literature evaluating the association between the destination hospital's capability (cardiac resuscitation center or not) and resuscitation outcomes for adult patients suffering from an out‐of‐hospital cardiac arrest was performed. Methods and Results PubMed, EMBASE, and the Cochrane Library databases were first searched using a specifically designed search strategy. Both original randomized controlled trials and observational studies were considered for inclusion. Cardiac resuscitation centers were defined as having on‐site percutaneous coronary intervention and targeted temperature management capability at all times. The primary outcome measure was survival. Twelve nonrandomized observational studies were retained in this review. A total of 61 240 patients were included in the 10 studies that could be included in the meta‐analysis regarding the survival outcome. Being transported to a cardiac resuscitation center was associated with an increase in survival (odds ratio=1.95 [95% confidence interval 1.47‐2.59], P<0.001). Conclusions Adult patients suffering from an out‐of‐hospital cardiac arrest transported to cardiac resuscitation centers have better outcomes than their counterparts. When possible, it is reasonable to transport these patients directly to cardiac resuscitation centers (class IIa, level of evidence B, nonrandomized).

Comparison of Long-Term Survival Following Sudden Cardiac Arrest in Men Versus Women. Am J Cardiol 2019; 124:362-366. [PMID: 31103131 DOI: 10.1016/j.amjcard.2019.04.051] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 04/16/2019] [Accepted: 04/25/2019] [Indexed: 02/04/2023]
Abstract
Sudden cardiac death (SCA) is a major cause of mortality with estimates of 450,000 deaths annually in the United States. The incidence of SCA differs between the sexes. Data regarding survival of women compared with men after SCA are, however, conflicting. We, therefore, examined the long-term survival of women versus men after SCA. A total of 1,433 (41% women; 44% out-of-hospital) survivors of SCA at our institution between 2002 and 2012 were followed to the primary end point of death through February 20, 2017. Women in our cohort were older (p = 0.02), were less likely to be white (p = 0.01), or to have suffered an acute myocardial infarction at the time of SCA (p < 0.001). They also had significantly shorter PR (p < 0.001) and QRS (p < 0.001) durations on their surface electrocardiogram, were more likely to present with an initial ventricular rhythm other than ventricular tachycardia or ventricular fibrillation (29% vs 22%, p = 0.001) and less likely to receive an implantable cardioverter defibrillator (22% vs 31%, p < 0.001). Over a median follow-up of 3.6 years, 674 (45%) patients died (53% women vs 43% men, p < 0.001). After adjusting for unbalanced baseline covariates, the sex difference in survival disappeared (hazard ratio 1.05; 95% confidence interval 0.85 to 1.29, p = 0.66). In conclusion, our results demonstrate comparable long-term mortality after SCA for men and women. Differences in unadjusted mortality are mainly due to older age, different risk profiles at the time of index event, and differential treatment with implantable cardioverter defibrillator.

When the Female Heart Stops: Sex and Gender Differences in Out-of-Hospital Cardiac Arrest Epidemiology and Resuscitation. Clin Ther 2019; 41:1013-1019. [PMID: 31053294 DOI: 10.1016/j.clinthera.2019.03.015] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 03/21/2019] [Accepted: 03/27/2019] [Indexed: 11/16/2022]
Abstract
Sex- and gender-based differences are emerging as clinically significant in the epidemiology and resuscitation of patients with out-of-hospital cardiac arrest (OHCA). Female patients tend to be older, experience arrest in private locations, and have fewer initial shockable rhythms (ventricular fibrillation/ventricular tachycardia). Despite standardized algorithms for the management of OHCA, women are less likely to receive evidence-based interventions, including advanced cardiac life support medications, percutaneous coronary intervention, and targeted temperature management. While some data suggest a protective mechanism of estrogen in the heart, brain, and kidney, its role is incompletely understood. Female patients experience higher mortality from OHCA, prompting the need for sex-specific research.

Association of health insurance with post-resuscitation care and neurological outcomes after return of spontaneous circulation in out-of-hospital cardiac arrest patients in Korea. Resuscitation 2019; 135:176-182. [PMID: 30639790 DOI: 10.1016/j.resuscitation.2018.12.023] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 10/15/2018] [Accepted: 12/18/2018] [Indexed: 01/09/2023]
Abstract
BACKGROUND We investigated the association of health insurance status with post-resuscitation care and neurological recovery in out-of-hospital cardiac arrest (OHCA) and whether the effects changed with age or gender. METHODS Adult OHCAs with presumed cardiac etiology who had sustained ROSC from 2013 to 2016 were enrolled from the nationwide OHCA registry of Korea. Insurance status was categorized into 2 groups: National Health Insurance (NHI) and Medical Aid (MA). The endpoints were post-resuscitation coronary reperfusion therapy (CRT), targeted temperature management (TTM), and good neurological recovery (cerebral performance category of 1 or 2). Multivariable logistic regression models and interaction analyses (insurance × age and insurance × gender) were conducted for adjusted odds ratios (aORs) and 95% confidence intervals (CI). RESULTS Of a total of 19,865 eligible OHCA patients, 18,119 (91.2%) were covered by NHI and 1746 (8.8%) by MA. The MA group was less likely to receive post-resuscitation CRT and TTM (aOR (95% CI): 0.75 (0.59-0.96) for CRT; 0.71 (0.57-0.89) for TTM) and had worse neurological outcomes (0.71 (0.57-0.89)) compared with the NHI group. In the interaction analyses, MA was associated with less CRT and good neurological recovery in the 45-64 year old group (0.54 (0.37-0.77) for CRT; 0.70 (0.51-0.95) for neurological outcome) and in the male group (0.69 (0.52-0.91) for CRT; 0.77 (0.61-0.97) for TTM; 0.70 (0.53-0.92)) for neurological outcome). CONCLUSIONS There were disparities in post-resuscitation care and substantial neurological recovery by health insurance status, and the disparities were prominent in middle-aged adults and males. Increasing health insurance coverage for post-resuscitation care should be considered.

Variation in outcomes among 24/7 percutaneous coronary intervention centres for patients resuscitated from out-of-hospital cardiac arrest. Resuscitation 2018; 135:14-20. [PMID: 30590071 DOI: 10.1016/j.resuscitation.2018.12.015] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 10/29/2018] [Accepted: 12/03/2018] [Indexed: 01/09/2023]
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.
