Exploration of cardiopulmonary resuscitation teamwork training for maternal cardiac arrest using the SimMan intelligent simulation platform: A simulation teaching study.

Maternal cardiac arrest is the most urgent clinical event in obstetrics and can lead to serious consequences, such as maternal or fetal death. Therefore, the training of team cardiopulmonary resuscitation (CPR) skills for obstetricians is essential. The aim of this study was to investigate the effect of applying intelligent simulation to CPR in maternal cardiac arrest teamwork training for obstetricians. Twenty-four obstetricians who participated in the "Maternal First Aid Workshop," organized by our hospital in 2018, were selected as training participants. The SimMan intelligent comprehensive patient simulator was used to train the CPR team collaboration with first-aid skills. Each team participating in the training was assessed before and after the training using a questionnaire survey. The evaluation of the results after the training showed that all four teams were qualified and that the timing of the cesarean section was 100% correct. The mean score, team collaboration score, and chest compression fraction were significantly higher than before training. Teamwork CPR assessment time, interruption time of chest compressions, and artificial airway establishment time were significantly shorter than before training. The questionnaire survey showed that 95.8% of the physicians reported that the training was rewarding and helpful to their clinical work, and 100% of the physicians believed that obstetricians require similar training. Using the SimMan intelligent comprehensive patient simulator to train obstetricians for CPR of maternal cardiac arrest teamwork first-aid skills can significantly improve the training effect, clinical first-aid skills, and teamwork awareness.

Does a Transition to Single-Occupancy Patient Rooms Affect the Incidence and Outcome of In-Hospital Cardiac Arrests?

It is proposed that patients in single-occupancy patient rooms (SPRs) carry a risk of less surveillance by nursing and medical staff and that resuscitation teams need longer to arrive in case of in-hospital cardiac arrest (IHCA). Higher incidences of IHCA and worse outcomes after cardiopulmonary resuscitation (CPR) may be the result. Our study examines whether there is a difference in incidence and outcomes of IHCA before and after the transition from a hospital with multibedded rooms to solely SPRs. In this prospective observational study in a Dutch university hospital, as a part of the Resuscitation Outcomes in the Netherlands study, we reviewed all cases of IHCA on general adult wards in a period of 16.5 months before to 16.5 months after the transition to SPRs. During the study period, 102 CPR attempts were performed: 51 in the former hospital and 51 in the new hospital. Median time between last-seen-well and start basic life support did not differ significantly, nor did median time to arrival of the CPR team. Survival rates to hospital discharge were 30.0% versus 29.4% of resuscitated patients (p = 1.00), with comparable neurological outcomes: 86.7% of discharged patients in the new hospital had Cerebral Performance Category 1 (good cerebral performance) versus 46.7% in the former hospital (p = .067). When corrected for telemetry monitoring, these differences were still nonsignificant. The transition to a 100% SPR hospital had no negative impact on incidence, survival rates, and neurological outcomes of IHCAs on general adult wards.

The attitude of the resuscitation team members and the patient’s companions toward the presence of the patient’s first-degree relatives during cardiopulmonary resuscitation in the emergency departments

The presence of the patient’s family at their bedside during cardiopulmonary resuscitation (CPR) is one of the challenging issues that has been frequently taken into consideration. Considering the importance of this topic. The objective of the present study was conducted to determine the attitude of the CPR team members and the patient’s companions toward the presence of the patient’s first-degree relatives during CPR.Materials and methods. The descriptive-analytical cross-sectional study was conducted on 100 CPR team members of two University Hospitals and 120 near relatives of patients undergoing CPR in 2021. The data were collected by the researcher-made questionnaire and depression, anxiety, stress scale (DASS) during CPR. The collected data were analyzed by SPSS (version 22) statistical software.Results. From the perspective of both the CPR team members and the patient’s companions, the highest mean response was related to the fact that it would be better for the patient to agree on the presence or absence of their family before hospitalization and whether they have favorable conditions. The attitude toward the presence of the patient’s family during CPR was statistically significantly associated with the companions’ gender (p < 0.05) and with the experience of work and participation in CPR of the CPR team members (p < 0.05).Conclusion. Taking into account the different opinions of the CPR team members and the patient’s relatives about the presence of family during resuscitation, additional studies with a large sample size should be carried out.

Establishing a Quality Improvement Program for Pediatric In-hospital Cardiac Arrest

Background: Pediatric In-hospital Cardiac Arrest (IHCA) is a rare event with a 50-55% mortality rate. Techniques of Cardiopulmonary Resuscitation (CPR), medication and electrical therapy timing, team dynamics, simulation and debriefing programs are associated with improved outcomes. This study aimed to improve outcomes after IHCA by describing and implementing quality improvement processes that cross and coordinate among traditional siloed pediatric resuscitation team structures. Methods: We chose three outcome measures: (1) return of spontaneous circulation (ROSC), (2) 24-hour survival after IHCA, and (3) survival to hospital discharge. Process outcomes include (1) hot debriefs performed with a standardized form, (2) code documentation using a revised form, and (3) formal code team review presented to a central Emergency Management Committee, using a standardized form. Results: One hundred and thirty-two patients experienced 176 events during the 36-month study period. Survival to hospital discharge increased from 33% during year 1 to 60% during year 2 (P < 0.05) but decreased to 45% in year 3. Both hot debrief performance and code documentation process methods did not demonstrate widespread adoption, but formal code team review was documented in 80% of events quite rapidly. Conclusions: There are common traits inherent to effective CPR team response. Ensuring optimal performance of these common tasks and techniques in every pediatric IHCA event in our hospital is being addressed by committee reorganization, task simplification, new technology acquisition and enhanced feedback loops. Early outcome analysis shows initial improvement in survival to hospital discharge after pediatric IHCA.

Intra-arrest transesophageal echocardiography during cardiopulmonary resuscitation.

Determining the cause of cardiac arrest (CA) and the heart status during CA is crucial for its treatment. Transesophageal echocardiography (TEE) is an imaging method that facilitates close observation of the heart without interfering with cardiopulmonary resuscitation (CPR). Intra-arrest TEE is a point-of-care ultrasound technique that is used during CPR. Intra-arrest TEE is performed to diagnose the cause of CA, determine the presence of cardiac contraction, evaluate the quality of CPR, assist with catheter insertion, and explore the mechanism of blood flow during CPR. The common causes of CA diagnosed using intra-arrest TEE include cardiac tamponade, aortic dissection, pulmonary embolism, and intracardiac thrombus, which can be observed on a few simple image planes at the mid-esophageal and upper esophageal positions. To operate an intra-arrest TEE program, it is necessary to secure a physician who is capable of performing TEE, provide appropriate training, establish implementation protocols, and prepare a plan in collaboration with the CPR team.

The Five-4-Life Quality Improvement Program: Improving Frontline Nurses' Cardiopulmonary Resuscitation Leadership and Team Management Skills.

Poor leadership and teamwork in cardiopulmonary resuscitation (CPR) are associated with poor patient outcomes. Frontline nursing staff frequently identify patients in cardiac arrest but may not have the initial leadership and teamwork skills to organize their initial rescue response. The Five-4-Life Quality Improvement (QI) program was pilot tested in a pediatric unit within a 510-bed acute care hospital in 2 phases: first, an educational program focused on leadership, team dynamics, and CPR skills, followed by sustaining interventions in the unit. Video recordings of 12 mock codes (4 pre-, 4 post-, 4 follow-up) were analyzed by trained observers. Descriptive statistical tests indicated a significant improvement in leadership, teamwork, and task management scores pre- and post-program, and sustained after the program. Implementing the Five-4-Life QI program is feasible in improving leadership, teamwork, and task management of first responding frontline nurses.

Improving Ventilation Rates During Pediatric Cardiopulmonary Resuscitation

Excessive ventilation at rates of 30 breaths per minute (bpm) or more during cardiopulmonary resuscitation (CPR) decreases venous return and coronary perfusion pressure, leading to lower survival rates in animal models. A review of our institution's pediatric CPR data revealed that patients frequently received excessive ventilation. We designed a multifaceted quality improvement program to decrease the incidence of clinically significant hyperventilation (≥30 bpm) during pediatric CPR. The program consisted of provider education, CPR ventilation tools (ventilation reminder cards, ventilation metronome), and individual CPR team member feedback. CPR events were reviewed pre- and postintervention. The first 10 minutes of each CPR event were divided into 20 second epochs, and the ventilation rate in each epoch was measured via end-tidal carbon dioxide waveform. Individual epochs were classified as within the target ventilation range (<30 bpm) or clinically significant hyperventilation (≥30 bpm). The proportion of epochs with clinically significant hyperventilation, as well as median ventilation rates, were analyzed in the pre- and postintervention periods. In the preintervention period (37 events, 699 epochs), 51% of CPR epochs had ventilation rates ≥30 bpm. In the postintervention period (24 events, 426 epochs), the proportion of CPR epochs with clinically significant hyperventilation decreased to 29% (P < .001). Median respiratory rates decreased from 30 bpm (interquartile range 21-36) preintervention to 21 bpm (interquartile range 12-30) postintervention (P < .001). A quality improvement initiative grounded in improved provider education, CPR team member feedback, and tools focused on CPR ventilation rates was effective at reducing rates of clinically significant hyperventilation during pediatric CPR.

Factors Affecting Performance of Cardiopulmonary Resuscitation Team

Association between physician turnover and survival outcome after in-hospital cardiopulmonary resuscitation: A nationwide cohort study in South Korea

AimWe investigated the association between physician turnover and survival outcomes after in-hospital cardiopulmonary resuscitation (ICPR) in South Korea. MethodsThis population-based cohort study used the South Korean national registration database as the data source. All adult patients admitted to the hospital and who underwent ICPR between 1 January 2010 and 31 December 2019, were included. Patients who underwent ICPR in March were included in the turnover group, while those who underwent ICPR in the other months were included in the non-turnover group. Propensity score (PS) matching was performed. ResultsOverall, 298,676 adult patients who underwent ICPR in 2,553 South Korean hospitals were included in the analysis. Among them, 26,342 (8.8%) and 272,334 (91.2%) were included in the turnover and non-turnover groups, respectively. In total, 7,009 (26.6%) and 6,903 (26.2%) of the 26,342 patients each in the turnover and non-turnover groups, respectively, were discharged alive after ICPR. Using logistic regression analysis in the PS-matched cohort, the two groups did not show any significant association in the live discharge rate after ICPR (odds ratio: 1.02, 95% confidence interval: 0.98, 1.06; P = 0.295). This non-significant association was also observed in patients who underwent ICPR in tertiary general hospitals that had cardiopulmonary resuscitation teams for ICPR (P = 0.136). Moreover, the median survival time in the turnover and non-turnover groups was 4.0 days (95% confidence interval: 3.8 days, 4.2 days; log-rank test, P = 0.796). ConclusionSignificant association between physician turnover and survival outcomes was not observed after ICPR in South Korea.

Knowledge, Attitude and Decision-making of Nurses in the Resuscitation Team towards Terminating Resuscitation and Do-not-Resuscitate Order.

Making appropriate decisions for cardiopulmonary resuscitation (CPR) is very challenging for healthcare providers. This study aimed to evaluate knowledge, attitude, and decision making about do-not-resuscitate (DNR) and termination of resuscitation (ToR) among nurses in the resuscitation team. This descriptive cross-sectional study was conducted in April-September 2020. Participants were 128 nurses from the CPR teams of two hospitals in Kermanshah and Hamedan, Iran. A valid and reliable researcher-made instrument was used for data collection. Data were analyzed using the Chi-square, Fisher's exact, and Mann-Whitney U tests, the Spearman's correlation analysis, and the logistic and rank regression analyses. Only 22.7% and 37.5% of participants had adequate knowledge about ToR and DNR. The significant predictor of DNR and ToR knowledge was educational level and the significant predictors of decision making for CPR were educational level, gender, and history of receiving CPR-related education (P<0.05). When facing a cardiac arrest and indication of DNR or ToR, 12.5% of participants reported that they would not start CPR, 21.5% of them reported that they would terminate CPR, and 14.8% of them reported that they would perform slow code. The DNR decision had significant relationship with educational level, DNR knowledge, and ToR knowledge (P< 0.05), while the ToR decision had significant relationship with educational level and ToR knowledge (P<0.05). Nurses' limited DNR and ToR knowledge and physicians' conflicting orders and documentation can cause ethical challenges for nurses. Clear guidelines for DNR orders or TOR is necessary for nurses, in order to prevent any potential confusion, legal or psychosocial issues and concerns surrounding CPR and improve their involvement in CPR decision making process.

Human Reliability Analysis for Cardiopulmonary Resuscitation Process in Emergency Medicine Using a Modified Hybrid Method Based on the Markov Model and Fault Tree Analysis

Introduction:In emergency departments (ED), human reliability assessment is essential for improving the quality of treatment and preventing medical accidents. A medical accident is expressed as an injury to a patient caused by the negligence of a doctor or nurse who is providing medical care. This study aimed to assess the human reliability in the cardiopulmonary resuscitation (CPR) process and recommend some comments to minimize human errors and improve patient safety.Materials and Methods: The main factors in the CPR process (such as rate and depth of chest compression and rate of ventilation) are identified based on the American heart association (AHA) roles. Data were recorded during three months in the evening shifts in the ED and CPR room of Imam Reza Hospital in Mashhad, Iran. In total, 42 samples were collected, and a modified hybrid approach according to the fault tree analysis and Markov method was proposed for the analysis of CPR team (including emergency medicine, medical interns, and nurses) reliability in the resuscitation process. Finally, the important basic events (errors) were selected using the Boruta algorithm by R software.Results: An FTA-Markov-based hybrid method is considered to compute the human reliability in the CPR process. The obtained results from human reliability analysis using the sensitivity analysis via Boruta algorithm and the proposed hybrid method show that an interrupt between chest compression process for rhythm control, the cycle of CPR, the depth of chest compression, and the discussion about reversible causes are the most effective factors in the human reliability of CPR process.Conclusion:The human reliability of the CPR process in the ED has been assessed using a hybrid method based on the FTA and Markov method for the first time. To improve the quality of treatment and prevent medical accidents during the CPR process, the main factors in the process are identified, and then, the proposed hybrid method is used to calculate human reliability.

Simulation-Based Training Program to Improve Cardiopulmonary Resuscitation and Teamwork Skills for the Urgent Care Clinic Staff.

Lack of high-quality cardiopulmonary resuscitation (CPR) and effective team communication during cardiovascular emergencies could lead to poor patient outcomes and adverse events. Studies have shown that CPR psychomotor skills declined 3 months and plateaued up to 6 months after the completion of CPR training. The Urgent Care Clinic (UCC) interprofessional staff did not receive consistent training on CPR and teamwork skills beyond what was received from the biannual American Red Cross (ARC) Basic Life Support (BLS) training and semiannual Resuscitative Care Function mock cardiac arrest. Most participants took their last CPR training for more than 6 months (n = 12, 67%), between 3 and 6 months (n = 2, 11%), and within the last 3 months before the pre-intervention period (n = 4, 22%). The purpose of the project was to form an interprofessional team to lead the development and implementation of a theory- and evidence-based simulation-based training program to improve CPR and teamwork skills while enhancing patient safety and emergency medical readiness in the hospital and UCC. The quality improvement project utilized an interprofessional in situ simulation-based training to improve participants' CPR and teamwork skills. The UCC physicians, nurses, and medical technicians completed a CPR and teamwork simulation-based training with a high-fidelity mannequin, pre-simulation preparation, briefing, and debriefing. The project collected pre-intervention and post-intervention data for CPR competence and teamwork perceptions. A paired t-test was used to assess differences in participant CPR skills and Team Strategies to Enhance Performance and Patient Safety Teamwork Perceptions Questionnaire responses before and after the simulation-based training intervention. The 59th Medical Wing and the University of South Alabama Institutional Review Boards approved the quality improvement project. A total of 18 participants completed the ARC BLS and Team Strategies to Enhance Performance and Patient Safety simulation-based training. Most participants were medical technicians (n = 8, 44%), followed by physicians (n = 5, 28%) and (n = 5, 28%) nurses. There was a statistical significance in participants' ARC BLS scores, with a pre-simulation mean score of 45.42 and a post-simulation mean score of 89.21 (P = .000, 95% CI = 36.89-50.68). For Team Strategies to Enhance Performance and Patient Safety teamwork perceptions, there was a statistically significant increase in the participants' teamwork perception levels, with a pre-simulation mean score of 4.61 and a post-simulation mean score of 4.86 (P = .000, 95% CI = 0.20-0.31). Our results demonstrated that the participants' ARC BLS scores and UCC's team perceptions have increased after in situ simulation-based training. We did not assess the ideal time for re-training. We recommend a 3- to 6-month post-training assessment to determine the optimal time for a CPR and teamwork refresher training. A high-fidelity simulation-based program with trained facilitators that assess the healthcare providers' CPR and teamwork skills could enhance the delivery of high-quality CPR and execution of effective teamwork skills in their workplace.

Predictors of survival and good neurological outcomes after in-hospital cardiac arrest

Objectives: This study aimed to investigate the effect of the code blue activation system and factors affecting patients’ survival to discharge and neurologic outcomes after in-hospital cardiac arrest. Methods: We retrospectively reviewed the data of patients aged ≥ 18 years who experienced in-hospital cardiac arrest between July 2014 and September 2019 at a tertiary hospital. The outcomes included survival to hospital discharge and neurologic outcomes (cerebral performance category score). Results: In total, 605 patients were included. The rate of survival to discharge was 21.8%(n = 132), and the rate of sustained return of spontaneous circulation was 69.7% (n = 422). Predisposing conditions, such as sepsis, cancer, pneumonia, and use of vasopressors, were associated with poor prognosis, and the survival rate was low (P = 0.01). The rate of survival to discharge was higher in patients who underwent defibrillation (odds ratio: 2.48, 95% confidence interval: 1.36-4.53) than in those who did not. The median cardiopulmonary resuscitation (CPR) duration time was 11.0 and 26.5 min in the survival and non-survival groups, respectively (P &lt; 0.01). Code blue activation to CPR team arrival time (advanced cardiovascular life support activation time) was not significantly different within 1 minute in both groups (P = 0.95). Similarly, no differences in basic life support activation time and first time to defibrillation were observed between the survival and non-survival groups. Among survivors, factors affecting favorable neurologic outcomes were young age, cerebral performance before CPR, whether witnessed, admission days, and CPR duration. Conclusions: The compulsory availability of a systematic code blue activation is not sufficient. Further, appropriate monitoring and continuous observation are crucial for improving survival to discharge and neurologic outcomes and preventing cardiac arrest in high-risk patients.

Barriers to the success of cardiopulmonary resuscitation from the perspective of Iranian nurses: A qualitative content analysis

BackgroundThe survival rate following Cardiopulmonary Resuscitation (CPR) has been reported to be 7–26.7%. Various studies have shown that CPR failure is high in many countries. This study was aimed to explore the barriers to the success of CPR from the perspective of Iranian nurses. MethodsParticipants were 14 Iranian nurses recruited through purposive sampling. In-depth semi-structured interviews were used to collect data. Data were analyzed using qualitative content analysis. ResultsThe barriers to successful CPR were developed in three main categories and nine subcategories. Some of the barriers to CPR success were: “delayed attendance of the CPR team and start of CPR”, “inadequate experience and skill of the CPR team”, “poor access to special units”, “insufficient and deficient CPR equipment”, “poor CPR location”, “critical clinical conditions of the patient”, and “interference of the patient’s family members. ConclusionThe results showed that human and environmental factors can result in CPR failure. These barriers can be minimized by measures such as empowerment of the CPR team, and providing the necessary facilities and equipment.

Assessing the effect of arrival time of physician and cardiopulmonary resuscitation (CPR) team on the outcome of CPR.

IntroductionNegligence of proper time and poor performance of resuscitation team can lead to more mortality and negative consequences of cardiac arrest, as well as less survival. This study was conducted with objective of determining the arrival time of physician and resuscitation team to survive the victims of cardiopulmonary arrest.Materials and methodsIn this prospective and descriptive-analytic study, the resuscitation performance and the arrival time of resuscitation team in 143 inpatients who had been diagnosed with witnessed cardiopulmonary arrest were examined using a researcher-made checklist. Data analysis was performed using parametric and non-parametric statistical tests and SPSS.ResultsInitial survival rate was 26.6%. In general, the mean time of physician’s presence after the code announcement in minutes and seconds was 02:31 ± 01:22. It was also 02:24 ± 01:15 in successful cases and 02:34 ± 01:25 in unsuccessful cases. Independent t-test did not show a significant difference between the physician’s presence time and the rate of initial successful resuscitation (p = 0.504). The time of first shock after observing ventricular fibrillation/tachycardia (in minutes and seconds) was 01:30 ± 00:47. According to independent t-test, the aforementioned time was less than the mean time (02:31 ± 01:22) of physician’s presence (p < 0.001).ConclusionsIn this study, the initial survival rate in comparison to other regions in the country was almost more favorable and it was similar to global norms. In this study, the starting time of resuscitation was within the acceptable range. There was no relationship between the presence of physician and the initial survival rate of patients, as well as the use of defibrillator (by physician compared to other team members) and intubation with the initial survival rate. This could indicate the adequate performance of resuscitation team in the absence of physician on the condition of having sufficient knowledge and skill.

Abstract 247: Development and Evaluation of Standardized Communication for In-Hospital Resuscitation

Background: Recommendations for “standardized” communication during cardiopulmonary resuscitation (CPR) events to reduce interruptions in chest compressions (CCs) are lacking. We aimed to achieve consensus on standardized communication during in-hospital CPR, evaluate feasibility and potential to decrease CC pauses, mental task load, and frustration. Methods: Modified Delphi consensus surveys of International Liaison Committee on Resuscitation taskforce members to identify preferred communication for in-hospital cardiac arrest teams. Consensus was reached after-survey teleconference resolution by a team of interdisciplinary experts in communication and CPR. Feasibility was tested in 8 simulated CPR scenarios with physician team leaders randomized (1:1) to ‘standardized’ communication vs. “usual best practice”, closed loop communication. Team leaders watched a 3-min video and received a 10-min training on the assigned intervention before the CPR scenario. NASA task load index questionnaires were used to assess mental task load and frustration (0=lowest to 100=highest). Results: Modified Delphi consensus on standardized communication included: 1) preparing the team 15-30 seconds before interrupting CCs, 2) countdown for interruption synchronized with 5 CCs, 3) action words for stopping and resuming CCs, 4) action words for intubation and defibrillation. Among 8 CPR teams (4 standardized, 4 usual communication), median (Q1; Q3) CC interruption duration for rhythm check was significantly shorter, 5.3 (4.8; 6.8) vs. 9.4 (6.4; 13.0) sec for standardized vs. closed loop communication [p=0.02]. Median (Q1; Q3) scores of mental task load were 63 (33; 70) vs 85 (70; 96), [p=0.10] and frustration 10 (5; 34) vs 40 (26; 50) [p=0.11] for standardized vs. closed loop communication. Trained team leaders adhered to standardized phrases 77% of the time. Conclusion: Expert consensus for standardized communication during in-hospital CPR was achieved. Pilot simulation implementation of standardized communication demonstrated feasibility of team leader adherence, significantly decreased duration of CC interruption during rhythm checks, and a tendency to reduce team leader task load and frustration.

Prospective Evaluation of Cardiopulmonary Resuscitation Performed in Dogs and Cats According to the RECOVER Guidelines. Part 1: Prognostic Factors According to Utstein-Style Reporting.

Factors associated with positive cardiopulmonary resuscitation (CPR) outcomes defined according to the veterinary Utstein-style CPR reporting guidelines have not been described since implementation of the Reassessment Campaign on Veterinary Resuscitation (RECOVER) CPR clinical guidelines in 2012. The aims of this study were to assess factors associated with positive CPR outcomes at a U.S. veterinary teaching hospital, to re-evaluate these factors since implementation of the RECOVER guidelines compared to reported factors prior to their publication, and to identify potential additional factors since guideline publication. One-hundred and seventy-two dogs and 47 cats that experienced cardiopulmonary arrest (CPA) and had CPR performed were prospectively included in this observational study. Supervising clinicians were asked to complete a data form on CPR events immediately following completion of CPR efforts. Multivariable logistic regression was used to evaluate the effect of twenty hospital, animal, and arrest variables on the three patient outcomes “any return of spontaneous circulation (ROSC),” “sustained ROSC,” and survival to hospital discharge. Cats had significantly higher odds to achieve any ROSC [OR (95%CI) 2.72 (1.12–6.61), p = 0.028] and survive to hospital discharge than dogs [OR (95%CI) 4.87 (1.52–15.58), p = 0.008]. Patients had significantly lower odds of achieving any ROSC if CPA occurred during nighttime hours [OR (95%CI) nighttime = 0.52 (0.27–0.98), p = 0.043], and higher odds if CPA was witnessed [OR (95%CI) 3.45 (1.57–7.55), p = 0.002], if less people were involved in CPR efforts [OR (95%CI) 0.8 (0.66–0.96), p = 0.016], if pulses were palpable during CPR [OR (95%CI) 9.27 (4.16–20.63), p < 0.0005], and if an IV catheter was already in place at the time of CPA [OR (95%CI) 5.07 (2.12–12.07), p = 0.0003]. Odds for survival to hospital discharge were significantly higher if less people were involved in CPR efforts [OR (95%CI) 0.65 (0.46–0.91), p = 0.013] and for patients of the anesthesia service [OR (95%CI) 14.82 (3.91–56.17), p = 0.00007]. Overall, factors associated with improved CPR outcomes have remained similar since incorporation of RECOVER guidelines into daily practice. Witnessed CPA events and high-quality CPR interventions were associated with positive patient outcomes, emphasizing the importance of timely recognition and initiation of CPR efforts. An optimal CPR team size has yet to be determined.

When does team leadership fail during in-hospital resuscitation? – a qualitative study

Background: Team leadership performance is associated with cardiopulmonary resuscitation (CPR) quality but team leadership is often substandard during in-hospital CPR. Little is known about why and how team leadership fails during in-hospital CPR. This study aims to investigate reasons for substandard team leadership during in-hospital CPR.

The importance of nontechnical skills in leading cardiopulmonary resuscitation teams.

Cardiopulmonary resuscitation (CPR) is one of the important clinical competencies for medical trainees. Since the introduction of the first guidelines for CPR in 1966, further research has resulted in more recent updates. The latest in the UK was published in 2015 by the resuscitation council. The multidisciplinary nature of the resuscitation team requires a designated leader, capable of directing the team's effort and making decisions. There is evidence that leadership makes a difference in the performance of the resuscitation team and the outcome of patients. Research performed on leadership in emergency medicine highlighted the importance of the nontechnical skills displayed by CPR team leaders. Nontechnical skills refer to cognitive, behavioural and social skills that contribute to efficient team performance, such as task management, assertiveness, situational awareness, communication and decision-making. This review discusses the importance and applicability of nontechnical leadership skills in CPR based on current evidence in the literature and the clinical practice in UK hospitals.
