Incidence Of Cardiopulmonary Resuscitation Research Articles

Considerations on the Use of Neonatal and Pediatric Resuscitation Guidelines for Hospitalized Neonates and Infants: On Behalf of the American Heart Association Emergency Cardiovascular Care Committee and the American Academy of Pediatrics.

Between 0.25% and 3% of admissions to the NICU, PICU, and PCICU receive cardiopulmonary resuscitation (CPR). Most CPR events occur in patients <1 year old. The incidence of CPR is 10 times higher in the NICU than at birth. Therefore, optimizing the approach to CPR in hospitalized neonates and infants is important. At birth, the resuscitation of newborns is performed according to neonatal resuscitation guidelines. In older infants and children, resuscitation is performed according to pediatric resuscitation guidelines. Neonatal and pediatric guidelines differ in several important ways. There are no published recommendations to guide the transition from neonatal to pediatric guidelines. Therefore, hospitalized neonates and infants can be resuscitated using neonatal guidelines, pediatric guidelines, or a hybrid approach. This report summarizes the current neonatal and pediatric resuscitation guidelines, considers how to apply them to hospitalized neonates and infants, and identifies knowledge gaps and future priorities. The lack of strong scientific data makes it impossible to provide definitive recommendations on when to transition from neonatal to pediatric resuscitation guidelines. Therefore, it is up to health care teams and institutions to decide if neonatal or pediatric guidelines are the best choice in a given location or situation, considering local circumstances, health care team preferences, and resource limitations.

Trends in Incidences and Survival Rates in Pediatric In-Hospital Cardiopulmonary Resuscitation: A Korean Population-Based Study.

Background Although the outcome of cardiopulmonary resuscitation (CPR) is still unsatisfactory, there are few studies about temporal trends of in-hospital CPR incidence and mortality. We aimed to evaluate nationwide trends of in-hospital CPR incidence and its associated risk factors and mortality in pediatric patients using a database of the Korean National Health Insurance between 2012 and 2018. Methods and Results We excluded neonates and neonatal intensive care unit admissions. Incidence of in-hospital pediatric CPR was 0.58 per 1000 admissions (3165 CPR/5 429 471 admissions), and the associated mortality was 50.4%. Change in CPR incidence according to year was not significant in an adjusted analysis (P=0.234). However, CPR mortality increased significantly by 6.6% every year in an adjusted analysis (P<0.001). Hospitals supporting pediatric critical care showed 37.7% lower odds of CPR incidence (P<0.001) and 27.5% lower odds of mortality compared with other hospitals in the adjusted analysis (P<0.001), and they did not show an increase in mortality (P for trend=0.882). Conclusions Temporal trends of in-hospital CPR mortality worsened in Korea, and the trends differed according to subgroups. Study results highlight the need for ongoing evaluation of CPR trends and for further CPR outcome improvement among hospitalized children.

New Concept of a Surgical Hospitalist: Early Experience of Managing the Admission, Critical Care, Trauma Surgery Team

The demand for hospitalists is increasing due to decreasing numbers of clinical residents and increased concerns regarding patient safety. However, several limitations in the surgical hospitalist role exist. The personnel of the surgical hospitalist, rapid response team (RRT), surgical critical care, and trauma surgery teams were unified under the admission, critical care, and trauma surgery (ACTs) team at this institution. The ACTs target are patients with severe disease not undergoing general postoperative course, or patients with the potential for severe conversion. Two surgical intensivists are on duty once a week and oversee the intensive care unit (ICU), the back-up treatment of critically ill patients, and the immediate treatment of trauma patients. ACTs also participate in the surgical RRT and select patients with a high probability of severe exacerbation. Between 2019-2021, the cardiopulmonary resuscitation incidence per 1,000 hospitalized patients in the surgical department decreased significantly from 0.81 to 0.55. From March to December 2021, the ACTs team were involved with 101 of 158 surgical patients admitted to the ICU: 62 with postoperative status, 29 with severe trauma, and 10 transferred to the ICU via RRT screening. Based on our experience, the role of the ACTs team can help improve patient safety.

Racial and Ethnic Differences in Bystander CPR for Witnessed Cardiac Arrest

BackgroundDifferences in the incidence of cardiopulmonary resuscitation (CPR) provided by bystanders contribute to survival disparities among persons with out-of-hospital cardiac arrest. It is critical to understand whether the incidence of bystander CPR in witnessed out-of-hospital cardiac arrests at home and in public settings differs according to the race or ethnic group of the person with cardiac arrest in order to inform interventions.MethodsWithin a large U.S. registry, we identified 110,054 witnessed out-of-hospital cardiac arrests during the period from 2013 through 2019. We used a hierarchical logistic regression model to analyze the incidence of bystander CPR in Black or Hispanic persons as compared with White persons with witnessed cardiac arrests at home and in public locations. We analyzed the overall incidence as well as the incidence according to neighborhood racial or ethnic makeup and income strata. Neighborhoods were classified as predominantly White (>80% of residents), majority Black or Hispanic (>50% of residents), or integrated, and as high income (an annual median household income of >$80,000), middle income ($40,000–$80,000), or low income (<$40,000).ResultsOverall, 35,469 of the witnessed out-of-hospital cardiac arrests (32.2%) occurred in Black or Hispanic persons. Black and Hispanic persons were less likely to receive bystander CPR at home (38.5%) than White persons (47.4%) (adjusted odds ratio, 0.74; 95% confidence interval [CI], 0.72 to 0.76) and less likely to receive bystander CPR in public locations than White persons (45.6% vs. 60.0%) (adjusted odds ratio, 0.63; 95% CI, 0.60 to 0.66). The incidence of bystander CPR among Black and Hispanic persons was less than that among White persons not only in predominantly White neighborhoods at home (adjusted odds ratio, 0.82; 95% CI, 0.74 to 0.90) and in public locations (adjusted odds ratio, 0.68; 95% CI, 0.60 to 0.75) but also in majority Black or Hispanic neighborhoods at home (adjusted odds ratio, 0.79; 95% CI, 0.75 to 0.83) and in public locations (adjusted odds ratio, 0.63; 95% CI, 0.59 to 0.68) and in integrated neighborhoods at home (adjusted odds ratio, 0.78; 95% CI, 0.74 to 0.81) and in public locations (adjusted odds ratio, 0.73; 95% CI, 0.68 to 0.77). Similarly, across all neighborhood income strata, the frequency of bystander CPR at home and in public locations was lower among Black and Hispanic persons with out-of-hospital cardiac arrest than among White persons.ConclusionsIn witnessed out-of-hospital cardiac arrest, Black and Hispanic persons were less likely than White persons to receive potentially lifesaving bystander CPR at home and in public locations, regardless of the racial or ethnic makeup or income level of the neighborhood where the cardiac arrest occurred.

Suicide Risk in Survivors of Acute Respiratory Distress Syndrome: A Nationwide Cohort Study in South Korea.

Objective We aimed to examine the prevalence and risk factors of suicide among patients with acute respiratory distress syndrome (ARDS). Methods Data were extracted from the National Health Insurance Service database in South Korea. This study included all adults admitted to intensive care units with a diagnosis of ARDS from January 1, 2010 to December 31, 2019, who survived ≥365. The primary endpoint in this study was suicide within 1 year of an ARDS diagnosis, which was determined as death by a suicide attempt or self-harm. Results Analysis included 9,928 patients identified as ARDS survivors. One-year all-cause mortality occurred in 5,021 patients, 186 (1.9%) of which died by suicide. In multivariable Cox regression, older age, continuous renal replacement therapy, cardiopulmonary resuscitation incidence, history of self-harm or attempted suicide and concurrent substance abuse were associated with a higher risk of death by suicide among ARDS survivors. Conclusion During the 1-year follow-up period, 1.9% of ARDS survivors died by suicide in South Korea, and some factors were identified as potential risk factors for death by suicide. Knowledge of the factors associated with suicide might allow for earlier intervention to potentially reduce the death by suicide among ARDS survivors.

Will implementation of the Life-sustaining Treatment Decisions Act reduce the incidence of cardiopulmonary resuscitation?

Will implementation of the Life-sustaining Treatment Decisions Act reduce the incidence of cardiopulmonary resuscitation?

Changes in the incidence of cardiopulmonary resuscitation before and after implementation of the Life-Sustaining Treatment Decisions Act.

BackgroundThe Life-Sustaining Treatment (LST) Decisions Act allows withholding and withdrawal of LST, including cardiopulmonary resuscitation (CPR). In the present study, the incidence of CPR before and after implementation of the Act was compared. MethodsThis was a retrospective review involving hospitalized patients who underwent CPR at a single center between February 2016 and January 2020 (pre-implementation period, February 2016 to January 2018; post-implementation period, February 2018 to January 2020). The primary outcome was monthly incidence of CPR per 1,000 admissions. The secondary outcomes were duration of CPR, return of spontaneous circulation (ROSC) rate, 24-hour survival rate, and survival-to-discharge rate. The study outcomes were compared before and after implementation of the Act. ResultsA total of 867 patients who underwent CPR was included in the analysis. The incidence of CPR per 1,000 admissions showed no significant difference before and after implementation of the Act (3.02±0.68 vs. 2.81±0.75, P=0.255). The ROSC rate (67.20±0.11 vs. 70.99±0.12, P=0.008) and survival to discharge rate (20.24±0.09 vs. 22.40±0.12, P=0.029) were higher after implementation of the Act than before implementation. ConclusionsThe incidence of CPR did not significantly change for 2 years after implementation of the Act. Further studies are needed to assess the changes in trends in the decisions of CPR and other LSTs in real-world practice.

Palliative care consultation and end-of-life outcomes in hospitalized COVID-19 patients

RationaleThe impact of palliative care consultation on end-of-life care has not previously been evaluated in a multi-center study. ObjectivesTo evaluate the impact of palliative care consultation on the incidence of cardiopulmonary resuscitation (CPR) performed and comfort care received at the end-of-life in hospitalized patients with COVID-19. MethodsWe used the Society of Critical Care Medicine’s COVID-19 registry to extract clinical data on patients hospitalized with COVID-19 between March 31st, 2020 to March 17th, 2021 and died during their hospitalization. The proportion of patients who received palliative care consultation was assessed in patients who did and did not receive CPR (primary outcome) and comfort care (secondary outcome). Propensity matching was used to account for potential confounding variables. Measurements and Main Results3,227 patients were included in the analysis. There was no significant difference in the incidence of palliative care consultation between the CPR and no-CPR groups (19.9% vs. 19.4%, p = 0.8334). Patients who received comfort care at the end-of-life were significantly more likely to have received palliative care consultation (43.3% vs. 7.7%, p < 0.0001). After propensity matching for comfort care on demographic characteristics and comorbidities, this relationship was still significant (43.2% vs. 8.5%; p < 0.0001). ConclusionPalliative care consultation was not associated with CPR performed at the end-of-life but was associated with increased incidence of comfort care being utilized. These results suggest that utilizing palliative care consultation at the end-of-life may better align the needs and values of patients with the care they receive.

Epidemiology of Cardiopulmonary Resuscitation in Critically Ill Children Admitted to Pediatric Intensive Care Units Across England: A Multicenter Retrospective Cohort Study.

BackgroundCardiopulmonary arrests are a major contributor to mortality and morbidity in pediatric intensive care units (PICUs). Understanding the epidemiology and risk factors for CPR may inform national quality improvement initiatives.Methods and ResultsA retrospective cohort analysis using prospectively collected data from the Paediatric Intensive Care Audit Network database. The Paediatric Intensive Care Audit Network contains data on all PICU admissions in the United Kingdom. We identified children who received cardiopulmonary resuscitation (CPR) in 23 PICUs in England (2013–2017). Incidence rates of CPR and associated factors were analyzed. Logistic regression was used to estimate the size and precision of associations. Cumulative incidence of CPR was 2.2% for 68 114 admissions over 5 years with an incidence rate of 4.9 episodes/1000 bed days. Cardiovascular diagnosis (odds ratio [OR], 2.30; 95% CI, 2.02–2.61), age <1 year (OR, 1.84; 95% CI, 1.65–2.04), the Paediatric Index of Mortality 2 score on admission (OR, 1.045; 95% CI, 1.042–1.047) and longer length of stay (OR, 1.013; 95% CI, 1.012–1.014) were associated with increased odds of receiving CPR. We also found a higher risk of CPR associated with a history of preadmission cardiac arrest (OR, 20.69; [95% CI, 18.16–23.58) and for children with a cardiac condition admitted to a noncardiac PICU (OR, 2.75; 95% CI, 1.91–3.98). Children from Black (OR, 1.68; 95% CI, 1.36–2.07) and Asian (OR, 1.49; 95% CI, 1.28–1.74) racial/ethnic backgrounds were at higher risk of receiving CPR in PICU than White children.ConclusionsData from this first multicenter study from England provides a foundation for further research and evidence for benchmarking and quality improvement for prevention of cardiac arrests in PICU.

Analysis of avoidable cardiopulmonary resuscitation incidents with a part-time rapid response system in place.

Background:Although a rapid response system (RRS) can reduce the incidence of cardiopulmonary resuscitation (CPR) in general wards, avoidable CPR cases still occur. This study aimed to investigate the incidence and causes of avoidable CPR.Methods:We retrospectively reviewed the medical records of all adult patients who received CPR between April 2013 and March 2016 (35 months) at a tertiary teaching hospital where a part-time RRS was introduced in October 2012. Four experts reviewed all of the CPR cases and determined whether each event was avoidable.Results:A total of 192 CPR cases were identified, and the incidence of CPR was 0.190 per 1,000 patient admissions. Of these, 56 (29.2%) were considered potentially avoidable, with the most common cause being doctor error (n=32, 57.1%), followed by delayed do-not-resuscitate (DNR) placement (n=12, 21.4%) and procedural complications (n=5, 8.9%). The percentage of avoidable CPR was significantly lower in the RRS operating time group than in the RRS non-operating time group (20.7% vs. 35.5%; P=0.026). Among 44 avoidable CPR events (excluding cases related to DNR issues), the rapid response team intervened in only three cases (6.8%), and most of the avoidable CPR cases (65.9%) occurred during the non-operating time.Conclusions:A significant number of avoidable CPR events occurred with a well-functioning, part-time RRS in place. However, RRS operation does appear to lower the occurrence of avoidable CPR. Thus, it is necessary to extend RRS operation time and modify RRS activation criteria. Moreover, policy and cultural changes are needed prior to implementing a full-time RRS.

CPR and AEDs save lives: insuring CPR--AED education and CPR--AED access in schools.

Sudden cardiac arrest and sudden cardiac death are less common in children and adolescents than in the adult population. The outcomes from sudden cardiac arrest are generally quite poor in all ages and some data suggest that they are worse in the child and adolescent age group. In addition, the incidence of bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use is generally quite low although it is somewhat variable across communities. This review has been written in order to review the data for pediatric bystander CPR and AED use as it relates to out-of-hospital cardiac arrest (OHCA) survival. The purpose of this article is also to review endeavors at CPR--AED education in the context of improving both community bystander CPR/AED interventions and OHCA survival. Finally, this review will attempt to suggest some potential educational interventions in order to increase both bystander CPR-AED use and OHCA survival in local communities. Findings from several recent studies suggest that the incidence of bystander CPR--AED intervention is relatively low and that OHCA survival is also quite low in most communities. Several studies also suggest that community educational efforts can increase bystander CPR--AED interventions. The increase in OHCA survival may be attributed to the community educational efforts, yet that increase in survival is relatively small. A prospective high-school study has shown that in this very specific environment, a high incidence of CPR--AED use can be achieved, and that as a result the OHCA survival can be relatively high. It would be beneficial to attempt to ensure that all schools have a CPR--AED program along with a group of individuals trained to do CPR and use an AED. Not only should all schools have a cardiac emergency response plan (CERP) but all schools should have CPR--AED programs and all students should learn CPR and AED use prior to graduation. This strategy will ensure that we will have a community of individuals who would perform CPR and use an AED in the community and that in so doing we could increase the incidence of bystander CPR/AED use and increase the OHCA survival rate.

Survival after in-hospital cardiopulmonary resuscitation from 2003 to 2013: An observational study before legislation on the life-sustaining treatment decision-making act of Korean patients.

We analyzed cardiopulmonary resuscitation (CPR) rates, deaths preceded by CPR, and survival trends after in-hospital CPR, using a sample of nationwide Korean claims data for the period 2003 to 2013.The Korean National Health Insurance Service–National Sample Cohort is a stratified random sample of 1,025,340 subjects selected from among approximately 46 million Koreans. We evaluated the annual incidence of CPR per 1000 admissions in various age groups, hospital deaths preceded by CPR, and survival rate following in-hospital CPR. Analyses of the relationships between survival and patient and hospital characteristics were performed using logistic regression analysis.A total of 5918 in-hospital CPR cases from 2003 to 2013 were identified among eligible patients. The cumulative incidence of in-hospital CPR was 3.71 events per 1000 admissions (95% confidence interval 3.62–3.80). The CPR rate per 1000 admissions was highest among the oldest age group, and the rate decreased throughout the study period in all groups except the youngest age group. Hospital deaths were preceded by in-hospital CPR in 18.1% of cases, and the rate decreased in the oldest age group. The survival-to-discharge rate in all study subjects was 11.7% during study period, while the 6-month and 1-year survival rates were 8.0% and 7.2%, respectively. Survival tended to increase throughout the study period; however, this was not the case in the oldest age group. Age and malignancy were associated with lower survival rates, whereas myocardial infarction and diabetes mellitus were associated with higher survival rates.Our result shows that hospital deaths were preceded by in-hospital CPR in 18.1% of case, and the survival-to-discharge rate in all study subjects was 11.7% during the study period. Survival tended to increase throughout the study period except for the oldest age group. Our results provide reliable data that can be used to inform judicious decisions on the implementation of CPR, with the ultimate goal of optimizing survival rates and resource utilization.

The Characteristics and Outcomes of Cardiopulmonary Resuscitation within the Neonatal Intensive Care Unit Based on Gestational Age and Unit Level of Care.

This study aimed to describe the variation of in-neonatal intensive care unit (NICU) cardiopulmonary resuscitation (CPR) characteristics and outcomes across different gestational ages and levels of NICU care. This is a retrospective cohort study of in-NICU CPR events across 10 NICUs in San Antonio, TX from 2012 through 2017. We identified 140 patients experiencing a total of 210 in-NICU CPR events. CPR was performed in 0.23% of Level III and 0.85% of Level IV NICU admissions. Gestational age was inversely related to CPR incidence. The median age at in-NICU CPR was lower for preterm versus term infants (6 vs. 28 days, p = 0.002). With regression modeling, each added minute of chest compression decreased the odds of return to spontaneous circulation by 11%. In-NICU CPR incidence rises with decreasing gestational age and increasing level of NICU care. The rate of return of spontaneous circulation decreases significantly with increasing duration of chest compressions. Further study is needed to identify patient factors associated with adverse outcome.

Abstract 120: Epidemiology and Outcomes of Cardiopulmonary Resuscitation Events in the Neonatal Intensive Care Unit

Introduction: Limited data exists regarding cardiopulmonary resuscitation (CPR) in infants in the Neonatal Intensive Care Unit (NICU). Objectives included determining the incidence, demographics, diagnoses, and outcomes of infants who require CPR across 10 NICUs in San Antonio, Texas. Methods: We conducted a retrospective review of in-NICU CPR events requiring chest compressions for 1 minute from 2012 - 2017. Included NICUs provided the following levels of care: two level IV, two high acuity level III, four low acuity level III, and two level II. Case identification occurred by reviewing death summaries and CPR coding in the electronic medical record. Results: In total, 139 infants (81 or 58% male) required 211 episodes of CPR. CPR incidence per 1000 patient days was 0.68, 0.37, 0.02 and 0 among level IV, high acuity level III, low acuity level III, and level II NICUs, respectively. Median birth weight was 945 (IQR 630, 2243) grams, gestational age at birth 27 (IQR 24, 34) weeks and age at CPR 11 (IQR 1, 42) days. Only 27 events (13%) occurred in term infants. Ninety-three CPR events (44%) had a primary respiratory etiology, 38 (18%) circulatory, 36 (17%) infectious, and 24 (11%) metabolic. Term and preterm infants had significantly different CPR etiologies (p=0.036). Circulatory etiologies were more common in term infants (37% vs 15%) with respiratory etiologies being less common (33.3% vs 46.2%). The most common rhythm documented leading to initiation of CPR was bradycardia (63%), followed by asystole (19%), and pulseless electrical activity (14%). The median duration of CPR was 10 (IQR 4, 25.5) minutes and chest compressions 8 (IQR 3, 18) minutes. While 135 of 211 CPR events (64%) had ROSC, only 22 of 139 patients (16%) survived to hospital discharge. The rate of ROSC among Level IV NICUs was significantly higher than in high acuity level III NICUs (68.2% vs 51.9%, p = 0.034). Conclusions: NICU CPR events occur most commonly in premature infants and are respiratory in origin. Bradycardia is the most common initial rhythm requiring CPR in the NICU. The incidence of CPR and the rate of ROSC are higher in level IV than level III NICUs. Further investigation is needed into factors associated with ROSC for in-NICU CPR.

Surgical pulmonary embolectomy and catheter-based therapies for acute pulmonary embolism: A contemporary systematic review

ObjectivesMortality in acute pulmonary embolism (PE) is believed to be principally due to the subgroup of PEs that are massive. Systemic thrombolysis is the therapeutic mainstay for acute massive PE, despite evidence suggesting limited survival benefits. Both catheter-based therapies (CBT) and surgical pulmonary embolectomy (SE) are well-accepted alternatives to treat acute PE. However, the comparative effectiveness of these approaches is difficult to study. We conducted a systematic review of CBT and SE for acute PE. MethodsThe PubMed database was queried for CBT- and SE-related publications between January 1998 and June 2017. A minimum of 10 patients undergoing intervention(s) was required for inclusion, and studies must not have excluded patients with massive PE. End points examined included hospital mortality, and additionally for CBT, procedural success rate. ResultsA total of 75 studies (41 of CBT, 34 of SE) were identified, with 1650 patients undergoing CBT and 1101 undergoing SE. Patients undergoing SE were more critically ill than those undergoing CBT (massive PE, 545 out of 975 [55.9%] for SE vs 742 out of 1553 [47.8%] for CBT). Cardiopulmonary resuscitation (CPR) was required in 217 out of 1015 patients undergoing SE (21.4%) versus 38 out of 983 patients undergoing CBT (4.0%). The hospital mortality of SE was 14.0%, versus 5.6% for CBT, in the entire patient group. However, the hospital mortality of SE in patients with pre-SE CPR was 46.3%, whereas it was 6.8% in those patients without pre-SE CPR. Although CPR was associated with an increased risk of mortality both for CBT and SE, it accounted for all of the mortality effect on SE (the adjusted odds ratio for CPR in a random effects model with treatment considered was 9.79 (95% confidence interval, 4.98-19.17; P < .0001). The adjusted odds ratio for mortality for SE relative to CBT was 1.36 (95% confidence interval, 0.80-2.32; P = .84). Moreover, CBT was associated with a procedural failure rate of 8.3%. ConclusionsBoth CBT and SE were associated with satisfactory published outcomes. SE is associated with greater absolute postprocedure mortality than CBT, but has been undertaken in more critically ill populations. The markedly higher incidence of CPR in SE accounts for the differential mortality between the patients undergoing SE and those undergoing CBT. Decision making with respect to best therapy must take into account potential needs for periprocedure artificial mechanical right ventricle and lung support, institutional experience and outcomes, anticipated therapeutic efficacy and benefit, and approach-specific risks.

Quality of dispatch-assisted cardiopulmonary resuscitation by lay rescuers following a standard protocol in Japan: an observational simulation study.

AimBystander cardiopulmonary resuscitation (CPR) is essential for improving the outcomes of sudden cardiac arrest patients. It has been reported that dispatch‐assisted CPR (DACPR) accounts for more than half of the incidence of CPR undertaken by bystanders. Its quality, however, can be suboptimal. We aimed to measure the quality of DACPR using a simulation study.MethodsWe recruited laypersons at a shopping mall and measured the quality of CPR carried out in our simulation. Dispatchers provided instruction in accordance with the standard DACPR protocol in Japan.ResultsTwenty‐three laypersons (13 with CPR training experience within the past 2 years and 10 with no training experience) participated in this study. The median chest compression rate and depth were 106/min and 33 mm, respectively. The median time interval from placing the 119 call to the start of chest compressions was 119 s. No significant difference was found between the groups with and without training experience. However, subjects with training experience more frequently placed their hands correctly on the manikin (84.6% versus 40.0%; P = 0.026). Twelve participants (52.2%, seven in trained and five in untrained group) interrupted chest compressions for 3–18 s, because dispatchers asked if the patient started breathing or moving.ConclusionThis current simulation study showed that the quality of DACPR carried out by lay rescuers can be less than optimal in terms of depth, hand placement, and minimization of pauses. Further studies are required to explore better DACPR instruction methods to help lay rescuers perform CPR with optimal quality.

Incidence, characteristics, and survival following cardiopulmonary resuscitation in the quaternary neonatal intensive care unit

BackgroundThe contemporary characteristics and outcomes of cardiopulmonary resuscitation (CPR) in the neonatal intensive care unit (NICU) are poorly described. The objectives of this study were to determine the incidence, interventions, and outcomes of CPR in a quaternary referral NICU. MethodsRetrospective observational study of infants who received chest compressions for resuscitation in the Children’s Hospital of Philadelphia NICU between April 1, 2011 and June 30, 2015. Patient, event, and survival characteristics were abstracted from the medical record and the hospital-wide resuscitation database. The primary outcome was survival to hospital discharge. Univariable and multivariable analyses were performed to identify patient and event factors associated with survival to discharge. ResultsThere were 1.2 CPR events per 1000 patient days. CPR was performed in 113 of 5046 (2.2%) infants admitted to the NICU during the study period. The median duration of chest compressions was 2min (interquartile range 1, 6min). Adrenaline was administered in 34 (30%) CPR events. Of 113 infants with at least one CPR event, 69 (61%) survived to hospital discharge. Factors independently associated with decreased survival to hospital discharge were inotrope treatment prior to CPR (adjusted Odds Ratio [aOR] 0.14, 95% Confidence Interval [CI] 0.04, 0.54), and adrenaline administration during CPR (aOR 0.14, 95% CI 0.04, 0.50). ConclusionsAlthough it was not uncommon, the incidence of CPR was low (<3%) among infants hospitalized in a quaternary referral NICU. Infants receiving inotropic therapy prior to CPR and adrenaline administration during CPR were less likely to survive to hospital discharge.

Outcome of Early Cardiopulmonary Resuscitation in Out-of-Hospital Cardiac Arrest Managed in Universiti Kebangsaan Malaysia Medical Centre

Out-of-hospital cardiac arrest (OHCA) patients require immediate cardiopulmonary resuscitation (CPR). Early initiation of CPR and defibrillation before arrival at Emergency Department (ED) increases the chance of survival from sudden cardiac arrest. The main objective of this study was to identify the factors that influenced the outcome of early cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA) patients managed at the ED of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). The second objective was to determine the incidence of CPR initiated by the public prior to ambulance arrival. The present study was a one-year cross-sectional study. The OHCA patients were identified from the ED resuscitation logbook. Patients’ medical records were used to obtain details of the resuscitation. Factors recorded included: aetiology of arrest, initiation of on-scene CPR, use of automated external defibrillators (AEDs), mode of transportation and the incidence of return of spontaneous circulation (ROSC) in the ED. Categorical data was analysed using chi-square and Fisher exact tests. Nine patients out of 98 had early CPR. Three patients achieved ROSC. Gender was significantly associated with ROSC (p-value=0.015). More patients who received early CPR achieved ROSC compared to those who received late CPR. The provision of early CPR and usage of AEDs by the public is still low. Female gender had a positive influence on ROSC. Efforts are required to increase the awareness and involvement of the public in initiating early CPR prior to the arrival of ambulance service.

Outcome of out-of-hospital cardiac arrest over a period of 15 years in comparison to the RACA score in a physician staffed urban emergency medical service in Germany

BackgroundPatient outcome after out of hospital cardiac arrest (OHCA) depends on the cardiopulmonary resuscitation (CPR) performance and might also be influenced by organisation of the emergency medical service (EMS) and implementation of guidelines. AimTo assess the rate of return of spontaneous circulation (ROSC) after cardiac arrest to the predicted rate by the ROSC after cardiac arrest (RACA) score over a 15-year period reflecting three different implemented ALS-guidelines in a physician-staffed EMS. MethodsAll adult patients with non-traumatic OHCA in the EMS of Bonn from 1996 to 2011 were included. Utstein data from three 5-years time periods (1996–2001, 2001–2006, 2006–2011) representing different ALS-guideline implementations were collected. Group comparisons were made in terms of incidence, epidemiology and short-term outcome of CPR with emphasis on changes over time and factors of importance. In each group observed ROSC rate were compared to the predicted ROSC rates (the RACA score). ResultsCPR by the ALS unit was attempted in a total of 1989 patients (735, 666, and 588 patients in the first, second and third period, respectively). Average crude incidence of CPR per 100,000 person-years decreased over time (61.3; 55.5; 49.0/100,000/years) while patients treated were significantly older (65.5±16.5; 67.9±15; 68.9±15.7 (p<0.001)). Observed ROSC rates were higher than predicted by the RACA score in all time periods, however, admittance to ICU decreased significantly from 50% in the first five-year period to 38% last five-year period (p<0.001). From first to third period the proportion of arrests with first observed rhythm of VT/VF arrests did not change (29% vs. 27%, p=0.323) nor there were changes in bystander CPR rates (17% vs. 17%, p=0.520). ConclusionsIn a 15-years period and in the setting of a physician-staffed EMS the ROSC rates remain higher than predicted by the RACA score but the admittance to the ICU after OHCA declined significantly. This finding was accompanied by a decrease in CPR incidence and an increase in age of patients.
