The Cardiac Surgery Advanced Life Support Course (CALS): Delivering Significant Improvements in Emergency Cardiothoracic Care

Cardiac Surgical Unit-Advanced Life Support-certified centers are associated with improved failure to rescue after cardiac arrest: A propensity score-matched analysis

OBJECTIVE

The impact of Cardiac Surgical Unit-Advanced Life Support (CSU-ALS) training on failure to rescue after cardiac arrest (FTR-CA) is unknown. We hypothesized that institutional CSU-ALS certification would be associated with lower FTR-CA.

METHODS

Patients undergoing Society of Thoracic Surgeons index operations from 2020 to 2023 from a regional collaborative were analyzed. Each institution was surveyed regarding its status as a CSU-ALS-certified center. Patients stratified by CSU-ALS certification were 1:1 propensity score matched with subsequent multivariable model reviewing associations with FTR-CA.

RESULTS

A total of 12,209 patients were included in the study period across 15 institutions. Eight centers reported CSU-ALS certification. After propensity score matching, 2 patient cohorts were formed (n = 3557). Patients at CSU-ALS centers had greater rates of intensive care unit readmission (3.9% vs 2.3%, P < .01) and total operating room time (340 minutes vs 323 minutes, P < .01). Hospital readmission was less likely in the CSU-ALS centers (9.0% vs 10.1%, P < .01). There was no difference in the rate of postoperative cardiac arrest (1.8% vs 2.2%, P = .24) or operative mortality (2.5% vs 2.9%, P = .30). After risk adjustment, CSU-ALS centers (odds ratio, 0.30; 95% confidence interval, 0.12-0.72, P < .01) and greater-volume centers (odds ratio, 0.15; confidence interval, 0.03-0.74, P = .02) had reduced odds of FTR-CA.

CONCLUSIONS

Centers with CSU-ALS certification are associated with a lower risk-adjusted likelihood of FTR-CA. This highlights the importance of well-trained staff and treatment algorithms in the care of patients postcardiac surgery.

Modernization of Cardiac Advanced Life Support: Role and Value of Cardiothoracic Anesthesiologist Intensivist in Post-Cardiac Surgery Arrest Resuscitation

Cardiac arrest in the postoperative cardiac surgery patient requires a unique set of management skills that deviates from traditional cardiopulmonary resuscitation and Advanced Cardiovascular Life Support (ACLS). Cardiac Advanced Life Support (CALS) was first proposed in 2005 to address these intricacies. The hallmark of CALS is early chest reopening and internal cardiac massage within 5 minutes of the cardiac arrest in patients unresponsive to basic life support. Since the introduction of CALS, the landscape of cardiac surgery has continued to evolve. Cardiac intensivists encounter more patients who undergo cardiac surgical procedures performed via minimally invasive techniques such as lateral thoracotomy or mini sternotomy, in which an initial bedside sternotomy for cardiac massage is not applicable. Given the heterogeneous nature of the patient population in the cardiothoracic intensive care unit, personnel must expeditiously identify the most appropriate rescue strategy. As such, we have proposed a modified CALS approach to (1) adapt to a newer generation of cardiac surgery patients and (2) incorporate advanced resuscitative techniques. These include rescue-focused cardiac ultrasound to aid in the early identification of underlying pathology and guide resuscitation and early institution of extracorporeal cardiopulmonary resuscitation instead of chest reopening. While these therapies are not immediately available in all cardiac surgery centers, we hope this creates a framework to revise guidelines to include these recommendations to improve outcomes and how cardiac anesthesiologist intensivists' evolving role can aid resuscitation.

Temporary Mechanical Circulatory Support after Cardiac Surgery

Postcardiotomy shock in the cardiac surgical patient is a highly morbid condition characterized by profound myocardial impairment and decreased systemic perfusion inadequate to meet end-organ metabolic demand. Postcardiotomy shock is associated with significant morbidity and mortality. Poor outcomes motivate the increased use of mechanical circulatory support (MCS) to restore perfusion in an effort to prevent multiorgan injury and improve patient survival. Despite growing acceptance and adoption of MCS for postcardiotomy shock, criteria for initiation, clinical management, and future areas of clinical investigation remain a topic of ongoing debate. This article seeks to (1) define critical cardiac dysfunction in the patient after cardiotomy, (2) provide an overview of commonly used MCS devices, and (3) summarize the relevant clinical experience for various MCS devices available in the literature, with additional recognition for the role of MCS as a part of a modified approach to the cardiac arrest algorithm in the cardiac surgical patient.

Nurses' roles and responsibilities in cardiac advanced life support: A single-site eDelphi study

BACKGROUND

Nurses are often the first responders to in-hospital cardiac arrest in postoperative cardiac surgical patients. Poor clarity about role expectations and responsibilities can hinder nurses' performance during cardiac advanced life support (CALS) procedures.

AIM

To seek expert consensus on nurses' roles and responsibilities in CALS for patients in postoperative cardiac surgical patients.

STUDY DESIGN

A two-round modified eDelphi survey. Delphi items were informed by guideline literature, an audit of resuscitation records and expert interviews. Panellists, drawn from a single site of a large tertiary health service in metropolitan Melbourne, included nurses, doctors and surgeons familiar with the management of cardiac arrest in post-operative cardiac surgical patients.

RESULTS

The two rounds of the modified eDelphi generated 55 responses. A consensus of >80% agreement was reached for 24 of the 41 statements in Round 2. All items related to nurses' roles and responsibilities during nurses pre- and post-arrest phases reached consensus. In contrast, only 29% (n = 4/14) of items related to peri-arrest, and 36% of those related to nurse scope of practise in CALS arrest (n = 4/11) reached consensus.

CONCLUSION

The study's aim was only partially achieved. Findings indicate high agreement about nurses' roles and responsibilities before and immediately after a cardiac arrest, but limited clarity about nurses' roles when implementing the CALS protocol, such as resternotomy and internal cardiac massage. There is an urgent need to address uncertainty about nurses' roles and scope of practice in CALS, which is essential to the recognition of nurses' contribution to the cardiac specialty workforce.

RELEVANCE TO CLINICAL PRACTISE

Uncertainty about nurses 'roles and responsibilities when implementing the CALS protocol may hinder their performance to their full scope of practice, leading to poor patient outcomes.

Virtual Reality Simulator versus Conventional Advanced Life Support Training for Cardiopulmonary Resuscitation Post-Cardiac Surgery: A Randomized Controlled Trial

External chest compressions are often ineffective for patients arresting after cardiac surgery, for whom emergency resternotomy may be required. A single-blinded randomized controlled trial (RCT) was performed, with participants being randomized to a virtual reality (VR) Cardiac Surgical Unit Advanced Life Support (CSU-ALS) simulator training arm or a conventional classroom CSU-ALS training arm. Twenty-eight cardiothoracic surgery (CTS) residents were included and subsequently assessed in a moulage scenario in groups of two, either participating as a leader or surgeon. The primary binary outcomes were two time targets: (1) delivering three stacked shocks within 1 min and (2) resternotomy within 5 min. Secondary outcomes were the number of protocol mistakes made and a questionnaire after the VR simulator. The conventional training group administered stacked shocks within 1 min in 43% (n = 6) of cases, and none in the VR group reached this target, missing it by an average of 25 s. The resternotomy time target was reached in 100% of the cases (n = 14) in the conventional training group and in 83% of the cases (n = 10) in the VR group. The VR group made 11 mistakes in total versus 15 for those who underwent conventional training. Participants reported that the VR simulator was useful and easy to use. The results show that the VR simulator can provide adequate CSU-ALS training. Moreover, VR training results in fewer mistakes suggesting that repetitive practice in an immersive environment improves skills.

Developing Cardiothoracic Surgical Critical Care Intensivists: A Case for Distinct Training

Cardiothoracic surgical critical care medicine is practiced by a diverse group of physicians including surgeons, anesthesiologists, pulmonologists, and cardiologists. With a wide array of specialties involved, the training of cardiothoracic surgical intensivists lacks standardization, creating significant variation in practice. Additionally, it results in siloed physicians who are less likely to collaborate and advocate for the cardiothoracic surgical critical care subspeciality. Moreover, the current model creates credentialing dilemmas, as experienced by some cardiothoracic surgeons. Through the lens of critical care anesthesiologists, this article addresses the shortcomings of the contemporary cardiothoracic surgical intensivist training standards. First, we describe the present state of practice, summarize past initiatives concerning specific training, outline why standardized education is needed, provide goals of such training standardization, and offer a list of desirable competencies that a trainee should develop to become a successful cardiothoracic surgical intensivist.

Virtual Reality Simulation Training for Cardiopulmonary Resuscitation After Cardiac Surgery: Face and Content Validity Study

BACKGROUND

Cardiac arrest after cardiac surgery commonly has a reversible cause, where emergency resternotomy is often required for treatment, as recommended by international guidelines. We have developed a virtual reality (VR) simulation for training of cardiopulmonary resuscitation (CPR) and emergency resternotomy procedures after cardiac surgery, the Cardiopulmonary Resuscitation Virtual Reality Simulator (CPVR-sim). Two fictive clinical scenarios were used: one case of pulseless electrical activity (PEA) and a combined case of PEA and ventricular fibrillation. In this prospective study, we researched the face validity and content validity of the CPVR-sim.

OBJECTIVE

We designed a prospective study to assess the feasibility and to establish the face and content validity of two clinical scenarios (shockable and nonshockable cardiac arrest) of the CPVR-sim partly divided into a group of novices and experts in performing CPR and emergency resternotomies in patients after cardiac surgery.

METHODS

Clinicians (staff cardiothoracic surgeons, physicians, surgical residents, nurse practitioners, and medical students) participated in this study and performed two different scenarios, either PEA or combined PEA and ventricular fibrillation. All participants (N=41) performed a simulation and completed the questionnaire rating the simulator's usefulness, satisfaction, ease of use, effectiveness, and immersiveness to assess face validity and content validity.

RESULTS

Responses toward face validity and content validity were predominantly positive in both groups. Most participants in the PEA scenario (n=26, 87%) felt actively involved in the simulation, and 23 (77%) participants felt in charge of the situation. The participants thought it was easy to learn how to interact with the software (n=24, 80%) and thought that the software responded adequately (n=21, 70%). All 15 (100%) expert participants preferred VR training as an addition to conventional training. Moreover, 13 (87%) of the expert participants would recommend VR training to other colleagues, and 14 (93%) of the expert participants thought the CPVR-sim was a useful method to train for infrequent post-cardiac surgery emergencies requiring CPR. Additionally, 10 (91%) of the participants thought it was easy to move in the VR environment, and that the CPVR-sim responded adequately in this scenario.

CONCLUSIONS

We developed a proof-of-concept VR simulation for CPR training with two scenarios of a patient after cardiac surgery, which participants found was immersive and useful. By proving the face validity and content validity of the CPVR-sim, we present the first step toward a cardiothoracic surgery VR training platform.

Resuscitation after cardiac surgery awareness: an Egyptian national survey

Background

Cardiac surgery patients have different resuscitative needs than other patients who experience in-hospital cardiac arrest; this was addressed in the guidelines. However, it is unknown how widely the guidelines are practiced, or a training protocol is followed in different cardiac surgery units in Egypt.

Methods

A 21-question survey was created and included: Participant demographics, prevalence of cardiac arrest, cardiac arrest protocol, emergency resternotomy technique, training protocols. Survey was disseminated through social media messaging platforms during the period between November 2020 and January 2021.

Results

Ninety-five responses were from 11 centres across Egypt. In total, 68.5% of the respondents were surgeons, 76.8% of participants were junior surgeons. For patients who go into VF after cardiac surgery, respondents would attempt a median of 3 shocks with only 24.2% commencing defibrillation shocks before external cardiac massage, whilst the majority initiating CPR immediately and performing emergency resternotomy in a median time of 10 min. In total, 56.8% would give 1 mg of adrenaline as soon as the cardiac arrest was established. If a surgeon was not available, only 36.8% of respondents would allow any trained personnel to perform the emergency resternotomy. Only 9.5% practice regularly on emergency sternotomies. Seventy-five percent think tailored training is important and staff should be oriented about it in the future.

Conclusion

An action plan is required to improve the training of the junior surgeons regarding the Cardiac Advanced Life Support Protocol to implement it in a timely organised manner. This should be endorsed and audited by a national society or body by keeping a national registry and mandatory recertification.

Characterizing Physician-Staffing Models in the Care of Postoperative Cardiac Surgical Patients in Canada

Background

Current intensive care unit physician-staffing (IPS) models for postoperative cardiac surgery have not been previously investigated in Canada. The purpose of this study was to determine current IPS models at 2 time points and describe the evolution of Canadian cardiac surgery IPS models.

Methods

A survey of 32 Canadian cardiovascular intensive care units (CVICUs) was undertaken in 2012 and 2017 to determine IPS models of care during “daytime” and “after-hours” in each unit. Data were collected regarding surgical volume, base specialties, and style of IPS management (“open”; “semi-open”; “closed”). In addition, we collected the overnight experience level of the bedside healthcare provider for in-house intensive care units.

Results

Survey responses were received from 27 of 32 CVICUs (87%). As of 2017, the style of 1 (4%) was open, 7 (26%) were semi-open, and 19 (70%) were closed in their unit IPS strategy. Base specialties of CVICU physicians varied. A medical doctor provided after-hours coverage in 81% of CVICUs. Senior residents (37%) or critical care certified attending staff (25%) typically provided after-hours coverage for in-house CVICUs. Linked Canadian Institute for Health Information data did not indicate a difference among CVICU models in mortality or rehospitalization for coronary artery bypass graft or valve procedures.

Conclusions

Considerable heterogeneity is demonstrated in CVICU staffing patterns. No consensus was identified regarding the appropriate level of training for “after-hours” coverage. In-house overnight physician staffing in CVICUs varies widely. Finally, semi-open and closed style models did not demonstrate differences compared to Canadian Institute for Health Information data. Variability among CVICUs does exist; however, benefits of one model over another have not been identified.

Impact of Bedside Re-Explorations in a Cardiovascular Surgery Intensive Care Unit Led by Surgeons

Surgical re-explorations represent 3-5% of all cardiac surgery. Concerns regarding mortality and major morbidity of re-explorations in the intensive care unit (ICU) setting exist. We sought to investigate whether they may have different outcomes compared with those performed in the operating room (OR). Single center retrospective review of patients who underwent mediastinal re-exploration in the ICU or in the OR after cardiac surgery. Mediastinal re-explorations were also classified as: "planned" and "unplanned". Primary outcome was 30-day mortality, secondary outcomes include deep sternal wound infection (DSWI), sepsis, ICU and hospital length of stay, prolonged intubation (>72 h), tracheostomy, pneumonia, acute kidney injury requiring dialysis and stroke. Between 2010 and 2019, 195 of 7263 patients (2.7%) underwent mediastinal re-exploration after cardiac surgery. More patients in the ICU group experienced two or more re-explorations (30.3% vs. 2.3%, p < 0.001), a higher incidence of postoperative pneumonia (22% vs. 7%, p = 0.004), prolonged intubation (46.8% vs. 19.8%, p < 0.001) and longer hospital stay (30.3 ± 34.2 vs. 20.8 ± 18.3 days, p = 0.014). There were no differences in mortality between ICU and OR (16.5% vs. 13.9%, p = 0.24) nor in sepsis (14.7% vs. 7%, p = 0.91) and DSWI rates (1.8% vs. 1.2%, p = 0.14). Re-explorations in the ICU were not associated with increased mortality, sepsis and mediastinitis rate.

Improving outcomes after low-risk coronary artery bypass grafting: understanding phase of care mortality analysis, failure to rescue and recent perioperative recommendations

PURPOSE OF REVIEW

Avoidable adverse events are responsible for up to 50% of deaths after low-risk coronary artery bypass grafting. This article reviews recent quality improvement efforts to improve outcomes after cardiac surgery.

RECENT FINDINGS

Systematic quality improvement methodology in cardiac surgery has improved significantly over the past decade. Contemporary efforts with phase of care mortality analysis (POCMA) focus on identifying and addressing root causes for mortality. Each patient's perioperative course is an interconnected sequence of clinical events, decisions, interventions, and treatment responses occurring across five perioperative phases. A single seminal event within a specific phase of care has been found to often trigger the eventual death of a patient. Several groups have made significant improvements to perioperative outcomes by addressing these avoidable mortality trigger events. Failing that, failure to rescue (FTR) metrics can be used to identify institutional factors responsible for poor perioperative outcomes. This ongoing focus on quality improvement serves to further improve outcomes after low-risk cardiac surgery.

SUMMARY

Modern quality improvement methodology, including POCMA and FTR analysis, has the potential to significantly improve outcomes after cardiac surgery. Larger future studies with multiinstitutional data sharing will be key to facilitate ongoing quality improvement and knowledge translation in this field.

[Cardiac arrest under special circumstances]

These guidelines of the European Resuscitation Council (ERC) Cardiac Arrest under Special Circumstances are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. This section provides guidelines on the modifications required for basic and advanced life support for the prevention and treatment of cardiac arrest under special circumstances; in particular, specific causes (hypoxia, trauma, anaphylaxis, sepsis, hypo-/hyperkalaemia and other electrolyte disorders, hypothermia, avalanche, hyperthermia and malignant hyperthermia, pulmonary embolism, coronary thrombosis, cardiac tamponade, tension pneumothorax, toxic agents), specific settings (operating room, cardiac surgery, cardiac catheterization laboratory, dialysis unit, dental clinics, transportation [in-flight, cruise ships], sport, drowning, mass casualty incidents), and specific patient groups (asthma and chronic obstructive pulmonary disease, neurological disease, morbid obesity, pregnancy).

Development of a porcine model of emergency resternotomy at a low-volume cardiac surgery centre

Emergency resternotomy in the intensive care unit (ICU) is a rarely performed, yet potentially life-saving intervention. Success relies on recognition of a deteriorating clinical condition, timely deployment of equipment/personnel and rapid execution. Given how infrequently it is performed, we sought to develop a large animal model of resternotomy to prepare ICU nurses and technicians at our low-volume cardiac surgery military centre. A porcine model of resternotomy was developed at the end of an already-scheduled trauma lab. Participants worked their way through a pre-planned simulation scenario, culminating in the need for resternotomy. Pre-simulation surveys assessing knowledge and comfort level with aspects of resternotomy were compared to post-simulation surveys. Participants improved their knowledge of resternotomy by 20.4% (P < 0.0001; 14.7% for nurses and 26.9% for technicians). Improvements were seen in all aspects assessed relating to subjective comfort/preparedness of resternotomy. The model was an effective and realistic method to augment training of ICU staff about resternotomy. Costs associated with this model can be reduced when used in conjunction with large animal labs. This model should be used together with mannequin-based methods of resternotomy training to provide a realistic training environment and assessment of skills at capable institutions.

Evaluation and Impact of the "Advanced Pediatric Life Support" Course in the Care of Pediatric Emergencies in Spain

INTRODUCTION

The Advanced Pediatric Life Support (APLS) course was introduced in the training of professionals who care for pediatric emergencies in Spain in 2005.

OBJECTIVE

To analyze the impact of the APLS course in the current clinical practice in Spanish PEDs.

METHODS

The directors of APLS courses were asked about information regarding the courses given to date, especially on the results of the satisfaction survey completed by students at the end of the course. Furthermore, in December 2014, a survey was conducted through Google Drive, specifically asking APLS students about the usefulness of the APLS course in their current clinical practice.

RESULTS

In the last 10 years since the APLS course was introduced in Spain, there have been 40 courses in 6 different venues. They involved a total of 1520 students, of whom 958 (63.0%) felt that the course was very useful for daily clinical practice. The survey was sent to 1,200 students and answered by 402 (33.5%). The respondent group most represented was pediatricians, 223 (55.5%), of whom 61 (27.3%) were pediatric emergency physicians, followed by pediatric residents, 122 (30.3%). One hundred three (25.6%) respondents had more than 10 years of professional practice and 291 (72.4%) had completed the course in the preceding four years. Three hundred forty-one of the respondents (84.9%: 95% confidence interval [CI], 81.9-87.9) said that they always use the pediatric assessment triangle (PAT) and 131 (32.6%: 95% CI, 28-37.1) reported that their organization has introduced this tool into their protocols. Two hundred twenty-three (55.5%: 95% CI, 50.6-60.3) believed that management of critically ill patients has improved, 328 (81.6%: 95% CI, 77.8-85.3) said that the PAT and the systematic approach, ABCDE, help to establish a diagnosis, and 315 (78.4%: 95% CI, 74.3-82.4) reported that the overall number of treatments has increased but that these treatments are beneficial for patients. Hospital professionals (191; 47.5%) include the PAT in their protocols more frequently than pre-hospital professionals (68.5% vs 55.4%; p <0.01) and consider PAT useful in the management of patients (60.2% vs 51.1%; p <0.05). Neither the time elapsed since the completion of the course, nor category and years of professional experience had any influence on the views expressed about the impact of the APLS course in clinical practice.

CONCLUSIONS

Most health professionals who have received the APLS course, especially those working in the hospital setting, think that the application of the systematic methods learned, the PAT and ABCDE, has a major impact on clinical practice.

The effectiveness of and satisfaction with high-fidelity simulation to teach cardiac surgical resuscitation skills to nurses

BACKGROUND

There are few reports of the effectiveness or satisfaction with simulation to learn cardiac surgical resuscitation skills.

OBJECTIVES

To test the effect of simulation on the self-confidence of nurses to perform cardiac surgical resuscitation simulation and nurses' satisfaction with the simulation experience.

METHODS

A convenience sample of sixty nurses rated their self-confidence to perform cardiac surgical resuscitation skills before and after two simulations. Simulation performance was assessed. Subjects completed the Satisfaction with Simulation Experience scale and demographics.

RESULTS

Self-confidence scores to perform all cardiac surgical skills as measured by paired t-tests were significantly increased after the simulation (d=-0.50 to 1.78). Self-confidence and cardiac surgical work experience were not correlated with time to performance. Total satisfaction scores were high (mean 80.2, SD 1.06) indicating satisfaction with the simulation. There was no correlation of the satisfaction scores with cardiac surgical work experience (τ=-0.05, ns).

CONCLUSION

Self-confidence scores to perform cardiac surgical resuscitation procedures were higher after the simulation. Nurses were highly satisfied with the simulation experience.

[Surgery in the Cardiovascular Surgical Intensive Care Unit]

BACKGROUND

To analyze the indications, actions and results of the operations performed in the Cardiovascular Surgery Intensive Care Unit.

METHODS

Retrospective analysis of consecutive non-selected adult patients operated in the ICU. All operations were included. Descriptive statistics were used.

RESULTS

Between 2008 and 2013, 3379 consecutive adult patients were operated upon. A total of 124 operations were performed in the ICU in 109 patients, 70 male (64.2%) and 39 female (35.8%) with a mean age of 61.6 years (12-80). This represented 3.2% of all operations. During the study period, 185 patients (5.5%) were reoperated for postoperative bleeding/tamponade in the operating room. The index interventions were for valvular heart disease (34.9%), aortic disease (22.9%), ischemic heart disease (15.6%), combined valvular/ischemic (12%), valvular/aorta (11%) and miscellaneous (3.6%). The indications for reoperation were persistent bleeding 54 (43.5%), pericardial tamponade 41 (33%), low cardiac output 13 (10.5%), cardiac arrest/arrhythmia 8 (6.5%), respiratory insufficiency 6 (4.8%) and acute ischemic limb 2 (1.7%). Operations performed were: mediastinal exploration 73 (58.9%), implant/removal of ECMO 17 (13.7%), sternal closure 16 (12.9%), open resuscitation 9 (7.3%), subxyphoid drainage 7 (5.6%) and femoral embolectomy 2 (1.6%). Overall mortality was 33%. There was one case of mediastinitis (0,9%), with no difference from patients operated in the regular operating room.

CONCLUSIONS

Operations in the ICU represent a safe, life-saving alternative in specific subgroups of patients. The risk of wound infection is not increased, unstable patients are not transferred and there is time savings.

A tool to improve competence in the management of emergency patients by rural clinic health workers: a pilot assessment on the Thai-Myanmar border

Background

Shoklo Malaria Research Unit has been providing health care in remote clinics on the Thai-Myanmar border to refugee and migrant populations since 1986 and 1995, respectively. Clinics are staffed by local health workers with a variety of training and experience. The need for a tool to improve the competence of local health workers in basic emergency assessment and management was recognised by medical faculty after observing the case mix seen at the clinic and reviewing the teaching programme that had been delivered in the past year (Jan-13 to March-14).

Aims

To pilot the development and evaluation of a simple teaching tool to improve competence in the assessment and management of acutely unwell patients by local health workers that can be delivered onsite with minimal resources.

Methods

A structured approach to common emergencies presenting to rural clinics and utilizing equipment available in the clinics was developed. A prospective repeated-measures observed structured clinical examination (OSCE) assessment design was used to score participants in their competence to assess and manage a scenario based ‘emergency patient’ at baseline, immediately post-course, and 8 weeks after the delivery of the teaching course. The assessment was conducted at 3 clinic sites and staff participation was voluntary. Participants filled out questionnaires on their confidence with different scenario based emergency patients.

Results

All staff who underwent the baseline assessment failed to carry out the essential steps in initial emergency assessment and management of an unconscious patient scenario. Following delivery of the teaching session, all groups showed improved competence in both objective assessment and subjective confidence levels.

Conclusions

Structured and practical teaching and learning with minimal theory in this resource limited setting had a positive short-term effect on the competence of individual staff to carry out an initial assessment and manage an acutely unwell patient. Health-worker confidence likewise improved. Workplace assessments are needed to determine if this type of skills training impacts upon mortality or near miss mortality patients at the clinic.

Six-year prospective audit of 'scoop and run' for chest-reopening after cardiac arrest in a cardiac surgical ward setting

OBJECTIVES

The aim of the study was to identify which cardiac surgical ward patients benefit from 'scoop and run' to the operating room for chest reopening.

METHODS

In-hospital arrests in a cardiothoracic hospital were prospectively audited over a 6-year period. The following pieces of information were collected for every patient who was scooped to the operating room following cardiac arrest on the postoperative cardiac surgical wards: type of arrest, time since surgery, patient physiology before arrest, time to chest reopening, location of chest opening, surgical findings on reopening, time to cardiopulmonary bypass (if used) and patient outcomes.

EXCLUSIONS

arrests in intensive care unit (ICU) and operating rooms. The primary outcome measure was survival to discharge from the hospital.

RESULTS

There were 99 confirmed ward arrests in 97 cardiac surgical patients. The overall survival rates to discharge and at 1 year were 53.6% (52 of 97 patients) and 44.3% (43 of 97 patients), respectively. Twenty-one of the 97 (21.6%) patients underwent scoop and run to the operating room or ICU. Five of 12 daytime 'scoop and runs' survived to discharge, whereas none of nine survived where scoop and run was undertaken at night (P < 0.05). There was a trend towards increased survival when 'scoop and run' was undertaken following ventricular fibrillation/pulseless ventricular tachycardia arrests (P = 0.06) and in younger patients (P = 0.12) but neither achieved statistical significance. The median time out from surgery of survivors was 4 days (range 2-14 days). The median time to chest opening in survivors was 22 min. Cardiopulmonary bypass was utilized in four of five survivors. The median ICU and hospital lengths of stay were 176 h (range 34-857) and 28 days (range 13-70), respectively.

CONCLUSIONS

The key determinant of a favourable 'scoop and run' outcome was whether the arrest occurred during daytime or night-time hours (P < 0.05). Despite a median time to chest opening of 22 min, all five survivors were discharged neurologically intact. The median time from surgery in these survivors was 4 days. Because of the risk of hypoxic brain damage, 'scoop and run' should be restricted to patients suffering witnessed arrests. The study has potential implications for resuscitation training and out-of-hours medical staffing in cardiothoracic hospitals.

What is the impact of structured resuscitation training on healthcare practitioners, their clients and the wider service? A BEME systematic review: BEME Guide No. 20

A large number of resuscitation training courses (structured resuscitation training programmes (SRT)) take place in many countries in the world on a regular basis. This review aimed to determine whether after attending SRT programmes, the participants have a sustained retention of resuscitation knowledge and skills after their initial acquisition and whether there is an improvement in outcome for patients and/or their healthcare organisation after the institution of an SRT programme. All research designs were included, and the reported resuscitation training had to have been delivered in a predefined structured manner over a finite period of time. Data was extracted from the 105 eligible articles and research outcomes were assimilated in tabular form with qualitative synthesis of the findings to produce a narrative summary. Findings of the review were: SRTs result in an improvement in knowledge and skills in those who attend them, deterioration in skills and, to a lesser extent, knowledge is highly likely as early as three months following SRTs, booster or refresher sessions may improve an individual's ability to retain resuscitation skills after initial training and the instigation of resuscitation training in a healthcare institution significantly improves clinical management of resuscitations and patient outcome (including survival) after resuscitation attempts.

The effect of the APLS-course on self-efficacy and its relationship to behavioural decisions in paediatric resuscitation

AIMS

Self-efficacy may predict performance following life-support training but may be negatively influenced by experiences during training. To investigate both this and the use of self-efficacy in self-assessment we investigated the relationship between self-efficacy and measured performance during a simulated resuscitation, and the effect of death of a simulated patient on self-efficacy.

MATERIALS AND METHODS

Consultant and trainee paediatricians and anaesthesiologists scored their self-efficacy for paediatric resuscitation skills before taking an unannounced simulated resuscitation test and objective structured clinical examination (OSCE)-tests of chest compressions and bag- and mask-ventilation. Performance in the simulation was scored by three independent expert observers and the OSCE's using a modified Berden and ventilation penalty scores.

RESULTS

Self-efficacy for the relevant skill was significantly higher in doctors choosing to give chest compressions, to intubate or insert an intraosseous device and in those who decided to intubate early. Self-efficacy correlated moderately with the quality of global performance on the simulation but not with the OSCE scores, nor was quality of individual skills during the simulation related to self-efficacy. Self-efficacy was higher in doctors who had taken the Advanced Paediatric Life Support (APLS)-course. Death of the simulated patient had a negative effect on self-efficacy.

CONCLUSION

Self-efficacy seems to be predictive of certain actions during a simulated resuscitation but does not correlate with quality of performance of resuscitation skills. Self-efficacy might therefore be useful as a predictor of the application of learning, but cannot be recommended for self-assessment. There is evidence to support the unwritten rule during simulation training the patient should not be allowed to die.

Effective performance of a new post-operative cardiac resuscitation simulation training scheme in the Paediatric Intensive Care Unit

OBJECTIVE

This feasibility study aimed to describe and evaluate the effectiveness of a novel chest re-opening paediatric resuscitation scenario training scheme.

METHODS

A novel scheme offering training on specialist skills required for post-operative cardiac patients such as chest re-opening and cardiac pacing via simulation was described. A prospective audit of the first 23 consecutive training sessions was conducted to assess the scheme's effectiveness. Parameters assessed included timing of chest re-opening or cardiac pacing orders, and any delays in carrying out these orders.

RESULTS

The median time required for the medical team leader to order chest re-opening was 4 min. New medical leaders took significantly longer to order chest re-opening than experienced medical team leaders (P = 0.02, Mann-Whitney U test). The performance of the team-in-training deteriorated with the introduction of new members but was correctable with serial training.

CONCLUSIONS

Effective simulation training integrating chest re-opening and cardiac pacing into standard paediatric resuscitation guidelines may be achieved without high fidelity simulation equipment.

In Situ Simulation-based Team Training for Post-cardiac Surgical Emergency Chest Reopen in the Intensive Care Unit

Emergency chest reopen of the post cardiac surgical patient in the intensive care unit is a high-stakes but infrequent procedure which requires a high-level team response and a unique skill set. We evaluated the impact on knowledge and confidence of team-based chest reopen training using a patient simulator compared with standard video-based training. We evaluated 49 medical and nursing participants before and after training using a multiple choice questions test and a questionnaire of self-reported confidence in performing or assisting with emergency reopen.

Both video- and simulation-based training significantly improved results in objective and subjective domains. Although the post-test scores did not differ between the groups for either the objective (P=0.28) or the subjective measures (P=0.92), the simulation-based training produced a numerically larger improvement in both domains. In a multiple choice question out of 10, participants improved by a mean of 1.9 marks with manikin-based training compared to 0.9 with video training (P=0.03). On a questionnaire out of 20 assessing subjective levels of confidence, scores improved by 3.9 with manikin training compared to 1.2 with video training (P=0.002).

Simulation-based training appeared to be at least as effective as video-based training in improving both knowledge and confidence in post cardiac surgical emergency resternotomy.
