Association of presence and timing of invasive airway placement with outcomes after pediatric in-hospital cardiac arrest

BackgroundLittle data exist regarding the association of presence of an invasive airway before cardiac arrest or early placement of an invasive airway after cardiac arrest with outcomes in children who experience in-hospital cardiac arrest.MethodsWe conducted a retrospective review of patients aged 1 day to 18 years who received cardiopulmonary resuscitation (CPR) for ≥1 min in any of the three intensive care units (ICUs) at a tertiary care, academic children's hospital between 2002 and 2010. Specific outcomes evaluated included survival to hospital discharge, return of spontaneous circulation (ROSC), 24-h survival, and good neurological status at hospital discharge. We fitted multivariable logistic regression models to evaluate the association between the presence of an invasive airway prior to cardiac arrest and timing of placement of an invasive airway with these outcomes.ResultsThree hundred and ninety-one patients were included. Of these, 197 (51%) patients were already tracheally intubated before the occurrence of cardiac arrest. Median time to intubation was 6 min [interquartile range (IQR): 2, 12] among the 194 patients tracheally intubated following cardiac arrest. We found lower survival to hospital discharge among patients intubated prior to cardiac arrest (intubated vs. non-intubated group, 43% vs. 61%, p < 0.001). After adjusting for patient and event characteristics, presence of an invasive airway prior to cardiac arrest was not associated with a significant improvement in survival to hospital discharge [odds ratio (OR): 0.70, 95% confidence interval (CI): 0.42–1.16, p = 0.17], or good neurological outcomes (OR: 0.60, 95% CI: 0.34–1.05, p = 0.07). Similarly, early placement of an invasive airway after cardiac arrest was also not associated with an improvement in survival to hospital discharge (OR: 1.05, 95% CI: 0.78–1.42, p = 0.73), or good neurological outcomes (OR: 1.08, 95% CI: 0.77–1.53, p = 0.65).ConclusionsOur study demonstrates that presence of an invasive airway prior to cardiac arrest or early placement of an invasive airway after cardiac arrest is not associated with an improvement in survival to hospital discharge or good neurological outcomes. Further study of the relationship between invasive airway management and survival following cardiac arrest is warranted.     

Higher achieved mean arterial pressure during therapeutic hypothermia is not associated with neurologically intact survival following cardiac arrest

IntroductionTo determine if higher achieved mean arterial blood pressure (MAP) during treatment with therapeutic hypothermia (TH) is associated with neurologically intact survival following cardiac arrest.MethodsRetrospective analysis of a prospectively collected cohort of 188 consecutive patients treated with TH in the cardiovascular intensive care unit of an academic tertiary care hospital.ResultsNeurologically intact survival was observed in 73/188 (38.8%) patients at hospital discharge and in 48/162 (29.6%) patients at a median follow up interval of 3 months. Patients in shock at the time of admission had lower baseline MAP at the initiation of TH (81 versus 87 mmHg; p = 0.002), but had similar achieved MAP during TH (80.3 versus 83.7 mmHg; p = 0.11). Shock on admission was associated with poor survival (18% versus 52%; p < 0.001). Vasopressor use among all patients was common (84.6%) and was not associated with increased mortality. A multivariable analysis including age, initial rhythm, time to return of spontaneous circulation, baseline MAP and achieved MAP did not demonstrate a relationship between MAP achieved during TH and poor neurological outcome at hospital discharge (OR 1.28, 95% CI 0.40–4.06; p = 0.87) or at outpatient follow up (OR 1.09, 95% CI 0.32–3.75; p = 0.976).ConclusionWe did not observe a relationship between higher achieved MAP during TH and neurologically intact survival. However, shock at the time of admission was clearly associated with poor outcomes in our study population. These data do not support the use of vasopressors to artificially increase MAP in the absence of shock. There is a need for prospective, randomized trials to further define the optimum blood pressure target during treatment with TH.     

Comparison of out-of-hospital cardiac arrest occurring before and after paramedic arrival: Epidemiology,survival to hospital discharge and 12-month functional recovery

BackgroundDespite immediate resuscitation, survival rates following out-of-hospital cardiac arrests (OHCA) witnessed by emergency medical service (EMS) are reportedly low. We sought to compare survival and 12-month functional recovery outcomes for OHCA occurring before and after EMS arrival.MethodsBetween 1st July 2008 and 30th June 2013, we included 8648 adult OHCA cases receiving an EMS attempted resuscitation from the Victorian Ambulance Cardiac Arrest Registry, and categorised them into five groups: bystander witnessed cases ± bystander CPR, unwitnessed cases ± bystander CPR, and EMS witnessed cases. The main outcomes were survival to hospital and survival to hospital discharge. Twelve-month survival with good functional recovery was measured in a sub-group of patients using the Extended Glasgow Outcome Scale (GOSE).ResultsBaseline and arrest characteristics differed significantly across groups. Unadjusted survival outcomes were highest among bystander witnessed cases receiving bystander CPR and EMS witnessed cases, however outcomes differed significantly between these groups: survival to hospital (46.0% vs. 53.4% respectively, p < 0.001); survival to hospital discharge (21.1% vs. 34.9% respectively, p < 0.001). When compared to bystander witnessed cases receiving bystander CPR, EMS witnessed cases were associated with a significant improvement in the risk adjusted odds of survival to hospital (OR 2.02, 95% CI: 1.75–2.35), survival to hospital discharge (OR 6.16, 95% CI: 5.04–7.52) and survival to 12 months with good functional recovery (OR 5.56, 95% CI: 4.18–7.40).ConclusionWhen compared to OHCA occurring prior to EMS arrival, EMS witnessed arrests were associated with significantly higher survival to hospital discharge rates and favourable neurological recovery at 12-month post-arrest.     

Epidemiology and outcomes of in-hospital cardiopulmonary resuscitation in the United States, 2000–2009

AimTo examine temporal trends in the epidemiology and outcomes of in-hospital cardiopulmonary resuscitation (CPR) recipients at a population level.MethodsRetrospective analysis of temporal trends in CPR incidence, survival to discharge, discharge disposition, hospital length of stay, and cost of hospitalization for CPR recipients (age ≥18years) captured in the Nationwide Inpatient Sample (2000–2009) in the United States.ResultsBetween years 2000 and 2009, CPR incidence increased by 33.7%, from 1 case per 453 to 1 case per 339 hospitalized patients (annual percentage increase: 4.3%, 95% CI: 3.4–5.2%, p < 0.001). Compared to CPR recipients in years 2000–2001, those in 2008–2009 were more often younger (age < 65 years: 33.4% vs. 40.0%), non-white (29.3% vs. 36.4%), and higher comorbidity scores (score ≥ 4: 22.2% vs. 27.1%) (all p < 0.001). Rates of neurologic compromise, mechanical ventilator, and feeding tube use increased by 37.7, 28.2, and 58.5%, respectively (all p < 0.001). Adjusted rate of survival to discharge increased by 41.3% (20.6–29.1%, p < 0.001). Compared to survivors in 2000, those discharged in 2009 were more often discharged to hospice (0.4% vs. 7.1%, p < 0.001); a 35% decrease in discharge to home was noted (36.4% vs. 23.8%, p < 0.001). Mean cost of hospitalization per day increased for both survivors ($2742–$3462, p = 0.006) and decedents ($3159–$4212, p < 0.001).ConclusionsThe rate of in-hospital CPR in the U.S. increased, and CPR recipients have become younger and sicker over time. Survival to discharge has improved by 41.3%. Functional outcomes after in-hospital CPR appear to have worsened, with considerable clinical and economic implications.     

History of diabetes mellitus as a neurologic predictor in comatose survivors of cardiac arrest of cardiac origin treated with mild hypothermia

AimTo investigate the impact of a history of diabetes mellitus on the neurologic outcome in comatose survivors of cardiac arrest of cardiac origin treated with mild hypothermia.MethodsA prospective observational study was performed between September 2003 and July 2008. Eighty comatose survivors of cardiac arrest of cardiac origin were treated with mild hypothermia. Neurologic outcome at the time of hospital discharge, 30-day survival, and complications were assessed.ResultsTwenty-four of the 80 patients (30%) had a history of diabetes. The rate of favorable neurologic outcome was significantly lower in diabetic (17%) than in nondiabetic patients (46%) (p = 0.01). The rate of 30-day survival was lower in diabetic (33%) than in nondiabetic patients (54%), but the difference was not significant (p = 0.10). Multivariate analysis suggested that a history of diabetes was an independent predictor of unfavorable neurologic outcome (odds ratio 7.00, 95% confidence interval 1.42–46.19, p = 0.03), but not for 30-day survival. There was no significant difference in the prevalence of complications.ConclusionA history of diabetes is associated with poor neurologic outcome in comatose survivors of cardiac arrest treated with mild hypothermia.     

Managing cardiac arrest with refractory ventricular fibrillation in the emergency department: Conventional cardiopulmonary resuscitation versus extracorporeal cardiopulmonary resuscitation

AimRefractory ventricular fibrillation, resistant to conventional cardiopulmonary resuscitation (CPR), is a life threatening rhythm encountered in the emergency department. Although previous reports suggest the use of extracorporeal CPR can improve the clinical outcomes in patients with prolonged cardiac arrest, the effectiveness of this novel strategy for refractory ventricular fibrillation is not known. We aimed to compare the clinical outcomes of patients with refractory ventricular fibrillation managed with conventional CPR or extracorporeal CPR in our institution.MethodThis is a retrospective chart review study from an emergency department in a tertiary referral medical center. We identified 209 patients presenting with cardiac arrest due to ventricular fibrillation between September 2011 and September 2013. Of these, 60 patients were enrolled with ventricular fibrillation refractory to resuscitation for more than 10 min. The clinical outcome of patients with ventricular fibrillation received either conventional CPR, including defibrillation, chest compression, and resuscitative medication (C-CPR, n = 40) or CPR plus extracorporeal CPR (E-CPR, n = 20) were compared.ResultsThe overall survival rate was 35%, and 18.3% of patients were discharged with good neurological function. The mean duration of CPR was longer in the E-CPR group than in the C-CPR group (69.90 ± 49.6 min vs 34.3 ± 17.7 min, p = 0.0001). Patients receiving E-CPR had significantly higher rates of sustained return of spontaneous circulation (95.0% vs 47.5%, p = 0.0009), and good neurological function at discharge (40.0% vs 7.5%, p = 0.0067). The survival rate in the E-CPR group was higher (50% vs 27.5%, p = 0.1512) at discharge and (50% vs 20%, p = 0. 0998) at 1 year after discharge.ConclusionsThe management of refractory ventricular fibrillation in the emergency department remains challenging, as evidenced by an overall survival rate of 35% in this study. Patients with refractory ventricular fibrillation receiving E-CPR had a trend toward higher survival rates and significantly improved neurological outcomes than those receiving C-CPR.     

Are high-sensitivity cardiac troponin I values stable between preoperative visit and day of non-cardiac surgery?

BackgroundIt is unclear if cardiac troponin values are stable in patients prior to undergoing non-cardiac surgery, or if they tend to rise towards the day of surgery.MethodsIn this small pilot study (n = 18) among patients with cardiac risk undergoing non-cardiac surgery, we determined if high-sensitivity cardiac troponin I (hscTnI) changes between the preoperative clinic visit and the day of surgery. HscTnI was measured on an Abbott Architect STAT (Abbott Laboratories, USA) platform.ResultsThe mean duration between preoperative clinic visit and day of surgery was 8.7 ± 2.8 (SD) days. Median hscTnI was 3.4 ng/L [2.0–4.8, IQR] at the preoperative visit and 2.8 ng/L [2.3–4.4] on the day of surgery (mean difference − 0.24 ng/L, 95% CI - 0.73 to 0.24 ng/L, p = 0.30). Only one patient had a large change (> 50%) along with symptoms.DiscussionEvidence from this small study suggests that cardiac troponin values are stable in most high-risk patients, absent clinical events, within 10 days prior to non-cardiac surgery.     

Effect of implementation of new resuscitation guidelines on quality of cardiopulmonary resuscitation and survival

BackgroundDuring cardiopulmonary resuscitation (CPR), advanced life support (ALS) providers have been shown to deliver inadequate CPR with long intervals without chest compressions. Several changes made to the 2005 CPR Guidelines were intended to reduce unnecessary interruptions. We have evaluated if quality of CPR performed by the Oslo Emergency Medical System (EMS) improved after implementation of the modified 2005 CPR Guidelines, and if any such improvement would result in increased survival.Materials and methodsRetrospective, observational study of all consecutive adult cardiac arrest patients treated during a 2-year period before (May 2003–April 2005), and after (January 2006–December 2007) implementation of the modified 2005 CPR Guidelines. CPR quality was assessed from continuous electronic recordings from LIFEPACK 12 defibrillators where ventilations and chest compressions were identified from transthoracic impedance changes. Ambulance run sheets, Utstein forms and hospital records were collected and outcome evaluated.ResultsResuscitation was attempted in 435 patients before and 481 patients after implementation of the modified 2005 CPR Guidelines. ECGs usable for CPR quality evaluation were obtained in 64% and 76% of the cases, respectively. Pre-shock pauses decreased from median (interquartile range) 17 s (11, 22) to 5 s (2, 17) (p = 0.000), overall hands-off ratios from 0.23 ± 0.13 to 0.14 ± 0.09 (p = 0.000), compression rates from 120 ± 9 to 115 ± 10 (p = 0.000) and ventilation rates from 12 ± 4 to 10 ± 4 (p = 0.000). Overall survival to hospital discharge was 11% and 13% (p = 0.287), respectively.ConclusionQuality of CPR improved after implementation of the modified 2005 Guidelines with only a weak trend towards improved survival to hospital discharge.     

The influence of age and chronic medical conditions on neurological outcomes in out of hospital cardiac arrest

AimIt is unknown whether older patients with out of hospital cardiac arrest (OHCA) have worse outcomes because of aging itself, or because age can be a marker for overall health status. We aimed to study the prognostic utility of age and pre-arrest comorbidities.MethodsWe conducted a retrospective cohort study, reviewing electronic health records of all adults treated for non-traumatic OHCA in the University of Michigan Emergency Department (N = 588). Primary covariates included age, Charlson Comorbidity Index (CCI), and a combined Charlson-age index. The primary dichotomized outcome was favorable neurological outcome (cerebral performance category, 1–2), evaluated by logistic regressions.ResultsDementia (p = 0.01), witnessed arrest (p = 0.03), bystander CPR (p < 0.001), presenting rhythm (p < 0.001), and mild therapeutic hypothermia (p < 0.001) were associated with the primary outcome. Increasing age (unadjusted OR for each decade of life, 95% CI: 0.78, 0.70–0.88; adjusted 0.79, 0.67–0.94) was negatively associated with likelihood of a favorable neurological outcome. CCI and combined Charlson-age index significantly predicted outcome in the unadjusted, but not adjusted analysis. Composite variables were stronger predictors in patients with shockable than non-shockable presenting rhythms (interaction terms: age and rhythm [p = 0.004], CCI and rhythm [p = 0.01]).ConclusionAge, but not CCI, was significantly associated with less favorable neurological outcomes in patients with OHCA after adjusting important covariates. Age appears to be an independent predictor of prognosis rather than a marker for comorbidity.     

Changes in health-related quality of life may predict recurrent breast cancer

BackgroundPatient-reported outcomes incorporated in cancer clinical trials, are increasingly hypothesized to be predictors of disease-free survival. Previous research supports health-related quality of life (HRQoL) as an independent predictor of survival in patients with advanced or metastatic breast cancer. In contrast, recent studies provide evidence that baseline HRQoL scores are not associated with increased risk of relapse or survival in women with early-stage breast cancer. One plausible assumption might be that baseline HRQoL scores are limited as predictors of a recurrence of breast cancer several years after the initial diagnosis. In this explorative study, we examined whether changes in HRQoL over time may predict breast cancer recurrence. As a supplement, we investigated whether baseline HRQoL predicted recurrence.MethodsThe study sample consisted of 141 participants in the International Breast Cancer Study Group adjuvant Trial 12-93 and Trial 14-93, from the Western region of Sweden. HRQoL was assessed, during a 5-year follow up. Poisson regression analysis was used to estimate the hazard function of recurrence depending on time since primary diagnosis and on HRQoL variables.ResultsAccording to the Poisson multivariable regression analysis changes in physical well-being (β = 0.00439, p-value = 0.0470), and nausea/vomiting (β = ?0.00612, p-value = 0.0136) significantly predicted recurrence. Baseline HRQoL outcomes were not predictors of recurrence.ConclusionsChanges of HRQoL during adjuvant therapy may be associated with recurrence. This explorative finding needs prospective investigation.     

The association of gasping and outcome,in out of hospital cardiac arrest: A systematic review and meta-analysis

ObjectiveGasping is common after cardiac arrest, and its frequency decreases over time. The aim of this study was to conduct a meta-analysis to evaluate the association of gasping and survival to discharge in patients who suffered out-of-hospital cardiac arrest.MethodsRelevant studies were identified by searching in PubMed, Medline, Embase, OVID, Web of Science and Google Scholar. Risk ratios (RR) and 95% confidence intervals (CI) were calculated to assess the association of gasping and on out-of-hospital cardiac arrest outcomes. Heterogeneity, subgroup analysis, sensitivity analysis and publication bias were explored.ResultsIndividual patient data was obtained from 10,797 participants suffered out-of-hospital cardiac arrest in five cohort studies of 4 articles. A fixed effects model suggested that patients with gasping were 3.525 times (95% CI: 3.028–4.104; P < 0.01) more likely to survive to discharge than those without gasping, and there was no heterogeneity among studies (P = 0.564). Also it may be a favorable factor for return of spontaneous circulation (RR: 2.170; 95% CI: 1.691, 2.785) with high heterogeneity (Q = 5.26; P = 0.022).ConclusionsFindings of this meta-analysis demonstrated that gasping is common after cardiac arrest, and is associated with increased survival to discharge. Patients who are cardiac arrest with gasping should be promptly resuscitated.     

Interaction effects between hypothermia and diabetes mellitus on survival outcomes after out-of-hospital cardiac arrest

ObjectivesMild therapeutic hypothermia (MTH) is the core hospital intervention to enhance neurological outcome after out-of-hospital cardiac arrest (OHCA). Diabetes mellitus (DM) has been known to be a harmful risk factor on survival after OHCA. This study aimed to investigate whether the effect of MTH on brain recovery after OHCA differed between patients with or without DM.MethodsWe used a Korean national OHCA database composed of hospital and ambulance data. We included adult OHCA patients who survived to admission with presumed cardiac etiology during the study period from 2009 to 2013. We excluded cases without hospital outcome data. The primary exposure was MTH, which included all kinds of cooling methods that had been initiated within 6 h after return of spontaneous circulation. DM was coded positive when the patient had a clinical history diagnosed by a physician before an OHCA event. The endpoints were discharge with good neurological recovery (cerebral performance category 1 or 2) and survival to discharge. We compared outcomes between MTH vs. non-MTH groups using multivariable logistic regression with an interaction term between MTH and DM for calculating adjusted odds ratios (AORs) and 95% confidence intervals (CIs) after adjusting for potential confounders.ResultsAmong 9735 patients following OHCA survived to hospital admission with cardiac etiology, MTH was performed in 16.5%. History of DM was observed in 25.4% among MTH group and 27.4% in non-MTH group (p = 0.09). MTH group showed better outcomes than non-MTH group; 23.6% vs. 15.7% for good neurological recovery (p < 0.01). AOR (95% CI) of MTH for good neurological recovery for all study groups was 1.23 (1.03–1.47). In the interaction model, AOR (95% CI) of MTH for good neurological recovery was 1.40 (1.16–1.70) in patients without DM vs. 0.69 (0.46–1.04) in patients with DM. For survival to discharge, the effects of MTH were different in patients without DM (1.97 (1.70–2.29)) and patients with DM (1.23 (0.96–1.57)).ConclusionDM modified the effect of MTH on survival and neurological outcomes for OHCA survivors. MTH is significantly associated with good neurological recovery in patients without DM, but not in patients with DM.     

In ICU state anxiety is not associated with posttraumatic stress symptoms over six months after ICU discharge: A prospective study

BackgroundPosttraumatic stress symptoms are common after intensive care treatment. The influence of anxiety during critical illness on the development of posttraumatic stress symptoms needs to be investigated.ObjectiveTo determine the association between anxiety during critical illness (state and trait components) and posttraumatic stress symptoms over six months after ICU discharge.MethodsProspective study including 141 patients admitted ≥24 h to a closed mixed adult ICU in a tertiary hospital. State anxiety was assessed with the Faces Anxiety Scale during ICU stay. Trait anxiety was measured with the State-Trait Anxiety Inventory Form Y-2. Posttraumatic stress symptoms were measured at three and six months after ICU discharge using the Post-Traumatic Stress Symptoms 10-Question Inventory. Clinical and demographical data were also collected. Mixed effect regression models were used to determine if state and trait anxiety were factors significantly associated with posttraumatic stress symptoms over time.ResultsModerate to severe levels of state anxiety in ICU were reported by 81 (57%) participants. Levels of trait anxiety (median 36 IQR: 29–47) were similar to the Australian population. High levels of posttraumatic stress symptoms occurred at three (n = 19, 19%) and six months (n = 15, 17%). Factors independently associated with posttraumatic stress symptoms were trait anxiety (2.2; 95% CI, 0.3–4.1; p = 0.02), symptoms of anxiety after ICU discharge (0.6; 95% CI, 0.2–1.1; p = 0.005), younger age (−1.4; 95% CI, −2.6 to −0.2; p = 0.02) and evidence of mental health treatment prior to the ICU admission (5.2; 95% CI, 1.5–8.9; p = 0.006).ConclusionsPosttraumatic stress symptoms occurred in a significant proportion of ICU survivors and were significantly associated with higher levels of trait anxiety, younger age, mental health treatment prior to the ICU admission and more symptoms of anxiety after ICU discharge. Early assessment and interventions directed to reduce state and trait anxiety in ICU survivors may be of benefit.     

Urban and rural differences in out-of-hospital cardiac arrest in Ireland

BackgroundMore than a third of Ireland's population lives in a rural area, defined as the population residing in all areas outside clusters of 1500 or more inhabitants. This presents a challenge for the provision of effective pre-hospital resuscitation services. In 2012, Ireland became one of three European countries with nationwide Out-of-Hospital Cardiac Arrest (OHCA) register coverage. An OHCA register provides an ability to monitor quality and equity of access to life-saving services in Irish communities.AimTo use the first year of national OHCAR data to assess differences in the occurrence, incidence and outcomes of OHCA where resuscitation is attempted and the incident is attended by statutory Emergency Medical Services between rural and urban settings.MethodsThe geographical coordinates of incident locations were identified and co-ordinates were then classified as ‘urban’ or ‘rural’ according to the Irish Central Statistics Office (CSO) definition.Results1798 OHCA incidents were recorded which were attended by statutory Emergency Medical Services (EMS) and where resuscitation was attempted. There was a higher percentage of male patients in rural settings (71% vs. 65%; p = 0.009) but the incidence of male patients did not differ significantly between urban and rural settings (26 vs. 25 males/100,000 population/year p = 0.353). A higher proportion of rural patients received bystander cardiopulmonary resuscitation (B-CPR) 70% vs. 55% (p ≤ 0.001), and had defibrillation attempted before statutory EMS arrival (7% vs. 4% (p = 0.019), respectively). Urban patients were more likely to receive a statutory EMS response in 8 min or less (33% vs. 9%; p ≤ 0.001). Urban patients were also more likely to be discharged alive from hospital (6% vs. 3%; p = 0.006) (incidence 2.5 vs. 1.1/100,000 population/year; p ≤ 0.001).Multivariable analysis of survival showed that the main variable of interest i.e. urban vs. rural setting was also independently associated with discharge from hospital alive (OR 3.23 (95% CI 1.43–7.31)).ConclusionThere are significant disparities in the incidence of resuscitation attempts in urban and rural areas. There are challenges in the provision of services and subsequent outcomes from OHCA that occur outside of urban areas requiring novel and innovative solutions. An integrated community response system is necessary to improve metrics around OHCA response and outcomes in rural areas.     

Cardiac rehabilitation availability and delivery in Brazil: a comparison to other upper middle-income countries

BackgroundBrazil has insufficient cardiac rehabilitation capacity, yet density and regional variation in unmet need is unknown. Moreover, South America has CR guidelines, but whether delivery conforms has not been described.ObjectiveThis study aimed to establish: (1) cardiac rehabilitation volumes and density, and (2) the nature of programmes, and (3) compare these by: (a) Brazilian region and (b) to other upper middle-income countries (upper-MICs).MethodsIn this cross-sectional study, a survey was administered to cardiac rehabilitation programmes globally. Cardiac associations were engaged to facilitate programme identification. Density was computed using Global Burden of Disease study ischaemic heart disease incidence estimates. Results were compared to data from the 29 upper-MICs with cardiac rehabilitation (N = 249 programmes).ResultsCardiac rehabilitation was available in all Brazilian regions, with 30/75 programmes initiating a survey (40.0% programme response rate). There was only one cardiac rehabilitation spot for every 99 ischaemic heart disease patient. Most programmes were funded by government/hospital sources (n = 16, 53.3%), but in 11 programmes (36.7%) patients depended on private health insurance. Guideline-indicated conditions were accepted in ≥70% of programmes. Programmes had a team of 3.8 ± 1.9 staff (versus 5.9 ± 2.8 in other upper-MICs, p < 0.05), offering 4.0 ± 1.6/10 core components (versus 6.0 ± 1.5 in other upper-MICs, p < 0.01; more tobacco cessation and return-to-work counselling needed in particular) over 44.5 sessions/patient (Q25–75 = 29–65) vs. 32 sessions/patient (Q25–75 = 15–40) in other upper-MICs (p < 0.01).ConclusionBrazilian cardiac rehabilitation capacity must be augmented, but where available, services are consistent across regions, but differ from other upper-MICs in terms of staff size and core components delivered.     

The development and testing of a nurse practitioner secondary prevention intervention for patients after acute myocardial infarction: A prospective cohort study

BackgroundPatients with acute myocardial infarction (AMI) are at high risk for reinfarction and death. Therapies that have been shown to reduce these risks (secondary prevention) continue to be underutilized. Nurse practitioners are well positioned to provide secondary prevention during and following hospitalization.ObjectivesThe purpose of this study was to evaluate the effects of NP care on the rate of provider implementation and patient achievement of evidence-based secondary prevention target goals.DesignA prospective cohort design was used, which compared achievement of target goals between patients who received secondary prevention care from an NP to those who received usual care.ParticipantsThe sample consisted of 65 patients with AMI, admitted to a large community hospital. Patients meeting eligibility criteria were recruited consecutively.MethodsThe intervention was delivered by the NP before discharge from hospital and one week, two weeks, six weeks and 3 months after discharge. Data on patients’ achievement of goals were obtained before discharge from hospital and 3 months after discharge from both groups.ResultsThis study's results provide preliminary evidence that an NP delivered secondary prevention intervention can significantly improve achievement of the following target goals when compared to usual care: smoking cessation (OR 5), blood pressure (OR 15), attendance at cardiac rehabilitation (OR 7), physical activity five days a week (OR 17), physical activity ≥ five days a week (OR 34), achieving a glycated haemoglobin < 7% in those with diabetes (OR 10), triglyceride levels (p = .02), statin use at follow-up (p = .05), and number of weeks to cardiac rehabilitation (p = .05).ConclusionNP-led interventions such as this warrant duplication to evaluate reproducibility of the intervention and to determine if short-term improvements in secondary prevention goals translate into morbidity and mortality benefits.     

Changes in treatments and outcomes among elderly patients with out-of-hospital cardiac arrest between 2002 and 2012: A post hoc analysis of the SOS-KANTO 2002 and 2012

BackgroundLittle is known about recent changes in pre- and in-hospital treatments and outcomes for elderly patients with out-of-hospital cardiac arrest (OHCA).MethodsWe compared data collected for the SOS-KANTO study in 2002 and 2012. We included patients aged ≥65 years who experienced OHCA of cardiac aetiology. The primary endpoint was favourable neurological outcomes 1 month after cardiac arrest.ResultsA total of 8,964 (2002 vs. 2012: 3,544 vs. 5,420) patients were eligible for the current analysis. The proportion of pre-hospital return of spontaneous circulation (ROSC) increased significantly (3.8 vs. 5.6%, p < 0.001). Among patients achieving ROSC, the proportion of advanced in-hospital treatments (i.e. extracorporeal membrane oxygenation, therapeutic hypothermia, and/or percutaneous coronary angiogram/intervention) provided increased significantly in 2012 (1.2 vs. 5.5%, p < 0.001; 2.6 vs. 15.1%, p < 0.001; 4.9 vs. 16.5%, p < 0.001; respectively). The proportion of favourable neurological outcomes at 1 month increased significantly in 2012 (1.6 vs. 2.7%, p = 0.001). A logistic regression analysis that did not consider advanced in-hospital treatments showed a significantly higher rate of favourable neurological outcomes in the 2012 group than that in the 2002 group (OR, 2.2; 95% CI, 1.4–3.5). However, this difference was no longer observed in the second regression model that accounted for advanced in-hospital treatments (OR, 1.6; 95% CI, 0.9–2.9).ConclusionThere was an increased proportion of aggressive treatment, both pre- and in-hospital, for elderly patients with cardiogenic OHCA in the Kanto area, Japan. Favourable neurological outcomes improved significantly over 10 years.     

Correlation between initial serum levels of lactate after return of spontaneous circulation and survival and neurological outcomes in patients who undergo therapeutic hypothermia after cardiac arrest

ObjectivesWe analysed the relationship between serum levels of lactate within 1 h of return of spontaneous circulation (ROSC) and survival and neurological outcomes in patients who underwent therapeutic hypothermia (TH).MethodsThis was a multi-centre retrospective and observational study that examined data from the first Korean Hypothermia Network (KORHN) registry from 2007 to 2012. The inclusion criteria were out-of-hospital cardiac arrest (OHCA) and examination of serum levels of lactate within 1 h after ROSC, taken from KORHN registry data. The primary endpoint was survival outcome at hospital discharge, and the secondary endpoint was poor neurological outcome (Cerebral Performance Category, CPC, 3–5) at hospital discharge. Initial lactate levels and other variables collected within 1 h of ROSC were analysed via multivariable logistic regression.ResultsData from 930 cardiac arrest patients who underwent TH were collected from the KORHN registry. In a total of 443 patients, serum levels of lactate were examined within 1 h of ROSC. In-hospital mortality was 289/443 (65.24%), and 347/443 (78.33%) of the patients had CPCs of 3–5 upon hospital discharge. The odds ratios of lactate levels for CPC and in-hospital mortality were 1.072 (95% confidence interval (CI) 1.026–1.121) and 1.087 (95% CI = 1.031–1.147), respectively, based on multivariate ordinal logistic regression analyses.ConclusionHigh levels of lactate in serum measured within 1 h of ROSC are associated with hospital mortality and high CPC scores in cardiac arrest patients treated with TH.     

Early targeted brain COOLing in the cardiac CATHeterisation laboratory following cardiac arrest (COOLCATH)

IntroductionTrials demonstrate significant clinical benefit in patients receiving therapeutic hypothermia (TH) after cardiac arrest. However, incidence of mortality and morbidity remains high in this patient group. Rapid targeted brain hypothermia induction, together with prompt correction of the underlying cause may improve outcomes in these patients. This study investigates the efficacy of Rhinochill^®, an intranasal cooling device over Blanketrol^®, a surface cooling device in inducing TH in cardiac arrest patients within the cardiac catheter laboratory.Methods70 patients were randomized to TH induction with either Rhinochill^® or Blanketrol^®. Primary outcome measures were time to reach tympanic ≤34 °C from randomisation as a surrogate for brain temperature and oesophageal ≤34 °C from randomisation as a measurement of core body temperature. Secondary outcomes included first hour temperature drop, length of stay in intensive care unit, hospital stay, neurological recovery and all-cause mortality at hospital discharge.ResultsThere was no difference in time to reach ≤34 °C between Rhinochill^® and Blanketrol^® (Tympanic ≤34 °C, 75 vs. 107 mins; p = 0.101; Oesophageal ≤34 °C, 85 vs. 115 mins; p = 0.151). Tympanic temperature dropped significantly with Rhinochill^® in the first hour (1.75 vs. 0.94 °C; p < 0.001). No difference was detected in any other secondary outcome measures. Catheter laboratory-based TH induction resulted in a survival to hospital discharge of 67.1%.ConclusionIn this study, Rhinochill^® was not found to be more efficient than Blanketrol^® for TH induction, although there was a non-significant trend in favour of Rhinochill^® that potentially warrants further investigation with a larger trial.
