Errors of Commission in Cardiac Arrest Care in the Intensive Care Unit.

INTRODUCTION: Cardiopulmonary arrests (CPAs) are common in the intensive care unit (ICU). However, effects of protocol deviations on CPA outcomes in the ICU are relatively unknown. OBJECTIVES: To establish the frequency of errors of commission (EOCs) during CPAs in the ICU and their relationship with CPA outcomes. METHODS: Retrospective analysis of data entered into institutional registry with inclusion criteria of age >18 years and non-traumatic cardiac arrest in the ICU. EOCs consist of administration of drugs or procedures performed during a CPA that are not recommended by ACLS guidelines.Primary outcome: relationship of EOCs with likelihood of return of spontaneous circulation (ROSC). Secondary outcomes: relationship of specific EOCs to ROSC and relationship of EOCs and CPA length on ROSC. RESULTS: Among 120 CPAs studied, there was a cumulative ROSC rate of 66%. Cumulatively, EOCs were associated with a decreased likelihood of ROSC (OR: 0.534, 95% CI: 0.387-0.644). Specifically, administration of sodium bicarbonate (OR: 0.233, 95% CI: 0.084-0.644) and calcium chloride (OR: 0.278, 95% CI: 0.098-0.790) were the EOCs that significantly reduced likelihood of attaining ROSC. Each 5-minute increment in CPA duration and/or increase in number of EOCs corresponded to fewer patients sustaining ROSC. CONCLUSIONS: EOCs during CPAs in the ICU were common. Among all EOCs studied, sodium bicarbonate and calcium chloride seemed to have the greatest association with decreased likelihood of attaining ROSC. Number of EOCs and CPA duration both seemed to have an inversely proportional relationship with the likelihood of attaining and sustaining ROSC. EOCs represent potentially modifiable human factors during a CPA through resources such as life safety nurses.

An update on allergic emergencies.

PURPOSE OF REVIEW: To provide an updated framework of management for allergic emergencies. RECENT FINDINGS: The most frequent causes of anaphylaxis include medications, foods, and stinging insects. Early and appropriate administration of epinephrine is critical to managing anaphylaxis. Although epinephrine is well tolerated and there is no absolute contraindication to using epinephrine in first-aid management of anaphylaxis, many patients at risk for anaphylaxis still fail to carry and use the medication prior to seeking emergency care. Outcomes of allergic emergencies can be improved by educational efforts that focus on adherence to emergency plans, as well as asthma controller treatments in patients with persistent asthma. Though venom immunotherapy is known to decrease the risk for stinging insect anaphylaxis, the role of emerging strategies for food allergen immunotherapy in reducing cases of anaphylaxis requires further study. SUMMARY: Fatalities resulting from anaphylaxis and asthma are rare. Patient education serves an important role in preparing for unexpected emergencies, instituting prompt and appropriate treatment, and incorporating effective strategies into the lives of children and families.

Improving Handoffs Between Operating Room and Pediatric Intensive Care Teams: Before and After Study.

INTRODUCTION: Patient transfer between teams and units is known to be a high-risk event for miscommunication and therefore error. We instituted a quality improvement initiative to formalize patient handoffs from the operating room (OR) to the Pediatric Intensive Care Unit (PICU). We hypothesized that measures of information transfer would improve. METHODS: In this before and after study, a multidisciplinary team developed a standardized handoff protocol (including a checklist) instituted in the Dartmouth PICU over the summer of 2016. We directly observed pediatric admissions from OR to PICU and collected data on information transfer and patient outcome metrics both before and after the institution of the handoff protocol at the time of transfer (intervention). RESULTS: We directly observed 52 handoffs (29 preintervention, 23 postintervention). The mean patient age was 9.3 years (SD, 6.5), with 55% male. Preintervention the average information transfer was 56% (upper control limit, 76%; lower control limit, 36%), whereas postintervention it was 81% (upper control limit, 97%, lower control limit, 65%). The improvement in information transfer postintervention was statistically significant (P < 0.001). There was no statistically significant change in maximum pain score in the first 6 hours after admission (preintervention, 4.5, SD 3.9; postintervention, 2.9, SD 1.3, P = 0.15). There was no difference in the time required for handoff pre- versus postintervention (8.7 minutes, SD 5.5 versus 10.1 minutes, SD 4.6, P = 0.34). CONCLUSION: Standardization of OR to PICU patient transfers using a predetermined checklist at the time of handoff can improve the completeness of information transfer without increasing the length of the handoff.

Rolling-refresher simulation improves performance and retention of paediatric intensive care unit nurse code cart management.

INTRODUCTION: Paediatric Intensive Care Unit Nurses (PICU RNs) manage the code cart during paediatric emergencies at the Children's Hospital at Dartmouth-Hitchcock. These are low -frequency, high-stakes events. METHODS: An uncontrolled intervention study with 6-month follow-up. A collaboration of physician and nursing experts developed a rolling-refresher training programme consisting of five simulated scenarios, including 22 code cart skills, to establish nursing code cart competency. The cohort of PICU RNs underwent a competency assessment in training 1. To achieve competence, the participating RN received immediate feedback and instruction and repeated each task until mastery during training 1. The competencies were repeated 6 months later, designated training 2. RESULTS: Thirty-two RNs participated in training 1. Sixteen RNs (50%) completed the second training. Our rolling-refresher training programme resulted in a 43% reduction in the odds of first attempt failures between training 1 and training 2 (p=0.01). Multivariate linear regression evaluating the difference in first attempt failure between training 1 and training 2 revealed that the following covariates were not significantly associated with this improvement: interval Paediatric Advanced Life Support training, interval use of the code cart or defibrillator (either real or simulated) and time between training sessions. Univariate analysis between the two trainings revealed a statistically significant reduction in first attempt failures for: preparing an epinephrine infusion (72% vs 41%, p=0.04) and providing bag-mask ventilation (28% vs 0%, p=0.02). CONCLUSIONS: Our rolling-refresher training programme demonstrated significant improvement in performance for low-frequency, high-risk skills required to manage a paediatric code cart with retention after initial training.

Current practice of neonatal resuscitation documentation in North America: a multi-center retrospective chart review.

BACKGROUND: To determine the comprehensiveness of neonatal resuscitation documentation and to determine the association of various patient, provider and institutional factors with completeness of neonatal documentation. METHODS: Multi-center retrospective chart review of a sequential sample of very low birth weight infants born in 2013. The description of resuscitation in each infant's record was evaluated for the presence of 29 Resuscitation Data Items and assigned a Number of items documented per record. Covariates associated with this Assessment were identified. RESULTS: Charts of 263 infants were reviewed. The mean gestational age was 28.4 weeks, and the mean birth weight 1050 g. Of the infants, 69 % were singletons, and 74 % were delivered by Cesarean section. A mean of 13.2 (SD 3.5) of the 29 Resuscitation Data Items were registered for each birth. Items most frequently present were; review of obstetric history (98 %), Apgar scores (96 %), oxygen use (77 %), suctioning (71 %), and stimulation (62 %). In our model adjusted for measured covariates, the institution was significantly associated with documentation. CONCLUSIONS: Neonatal resuscitation documentation is not standardized and has significant variation. Variation in documentation was mostly dependent on institutional factors, not infant or provider characteristics. Understanding this variation may lead to efforts to standardize documentation of neonatal resuscitation.

Evaluating simulation education via electronic surveys immediately following live critical events: a pilot study.

BACKGROUND AND OBJECTIVES: Simulation-based medical education has become popular in postgraduate training for medical emergencies; however, the direct impact on learners' clinical performances during live critical events is unknown. Our goal was to evaluate the perceived impact of simulation-based education on pediatric emergencies by auditing pediatric residents immediately after involvement in actual emergency clinical events. METHODS: Weekly team-based pediatric simulation training for inpatient emergencies was implemented in an academic tertiary care hospital. Immediately after actual pediatric emergency events, each resident involved was audited regarding roles, performed tasks, and perceived effectiveness of earlier simulation-based education. The audit was performed by using a Likert scale. RESULTS: From September 2010 through August 2011, a total of 49 simulation sessions were held. During the same period, 27 pediatric emergency events occurred: 3 code events, 14 rapid response team activations, and 10 emergency transfers to the PICU. Forty-seven survey responses from 20 pediatric residents were obtained after the emergency clinical events. Fifty-three percent of residents felt well prepared, and 45% reported having experienced a similar simulation before the clinical event. A preceding similar simulation experience was perceived as helpful in improving clinical performance. Residents' confidence levels, however, did not differ significantly between those who reported having had a preceding similar simulation and those who had not (median of 4 vs median of 3; P=.16, Wilcoxon rank-sum test). CONCLUSIONS: A novel electronic survey was successfully piloted to measure residents' perceptions of simulation education compared with live critical events. Residents perceived that their experiences in earlier similar simulations positively affected their performances during emergencies.

Effect of just-in-time simulation training on provider performance and patient outcomes for clinical procedures: a systematic review.

Background: Providing simulation training directly before an actual clinical procedure-or 'just-in-time' (JiT)-is resource intensive, but could improve both provider performance and patient outcomes. Objectives: To assess the effects of JiT simulation training versus no JiT training on provider performance and patient complications following clinical procedures on patients. Study selection: We searched MEDLINE, Cochrane Library, CINAHL, PsycINFO, ERIC, ClinicalTrials.gov, simulation journals indexes and references of included studies during October 2014 for randomised trials, non-randomised trials and before-after studies comparing JiT simulation training versus no JiT training among providers performing clinical procedures. Findings were synthesised qualitatively. Findings: Of 1805 records screened, 8 studies comprising 3540 procedures and 1969 providers were eligible. 5 involved surgical procedures; the other 3 included paediatric endotracheal intubations, central venous catheter dressing changes, or infant lumbar puncture. Methodological quality was high. Of the 8 studies evaluating provider performance, 5 favoured JiT simulation training with 18-48% relative improvement on validated clinical performance scales, 16-20% relative reduction in surgical time and 12% absolute reduction in corrective prompts during central venous catheter dressing changes; 3 studies were equivocal with no improvement in intubation success, lumbar puncture success or urological surgery clinical performance scores. 3 studies evaluated patient complications; 1 favoured JiT simulation training with 45% relative reduction in central line-associated blood stream infections; 2 studies found no differences following intubation or laparoscopic nephrectomy. Conclusions: JiT simulation training improves provider performance, but currently available literature does not demonstrate a reduction in patient complications.

Therapeutic plasma exchange in Streptococcus pneumoniae-associated hemolytic uremic syndrome: a case report.

Streptococcus pneumoniae-associated hemolytic uremic syndrome (pHUS) is an atypical form of HUS associated with microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. Although less common than diarrhea-associated HUS, incidence appears to be increasing. We report a case of a child with pHUS who underwent a course of therapeutic plasma exchange (TPE) and had complete recovery. This report adds to the existing literature supporting TPE in cases of pHUS.

Considerations on the use of adjunct red blood cell exchange transfusion in the treatment of severe Plasmodium falciparum malaria.

BACKGROUND: Travelers returning to the United States from malaria-endemic areas are at increased risk of a potentially fatal infection from Plasmodium falciparum, which requires prompt and aggressive treatment. STUDY DESIGN AND METHODS: Described is a case of a 7-year-old boy who was infected by P. falciparum while in Africa and developed features of severe infection, including hyperparasitemia, altered neurologic status, and malarial hepatitis. RESULTS: A single automated erythrocytapheresis procedure reduced parasitemia from 14% to less than 1%. Along with intravenous quinidine, this reduced parasite level was maintained throughout the hospitalization and the patient recovered. CONCLUSION: Exchange transfusion (ET) is an effective adjunct therapy to reduce the parasite load in cases of severe P. falciparum malaria. When performed in certain defined settings, the benefits can outweigh the risks of the procedure. Discussed are the medical and technical considerations on the use of adjunctive ET for severe P. falciparum infection and a review of the literature of the use of adjunct ET in the treatment of severe P. falciparum malaria.

Estimation of optimal CPR chest compression depth in children by using computer tomography.

OBJECTIVE: Pediatric consensus-driven cardiopulmonary resuscitation guidelines target chest compression (CC) depths of one third to one half anterior-posterior (AP) chest depth. Estimates for this target as assessed by computed tomography (CT) measurements of internal and external AP chest dimensions could direct future pediatric cardiopulmonary resuscitation guidelines. METHODS: A total of 280 consecutive chest CT scans in permuted blocks of 20 for each of 14 age divisions between 0 and 8 years were reconstructed and analyzed. External and internal AP depths were measured at midsternum, and residual chest depth was calculated at simulated one-third and one-half AP compressions. RESULTS: After a simulated compression calculation, one-half external AP depth CC would result in residual internal depth of <10 mm for 94% (263 of 280) of children 3 months to 8 years. For a one-third external AP CC, only 0.4% (1 of 280) of children 3 months to 8 years had a calculated residual internal chest depth <10 mm. CONCLUSIONS: By using CT reconstruction estimates of chest dimensions across the developmental spectrum from 0 to 8 years of age, we demonstrated that a simulated CC targeting approximately one-third external AP chest depth seems radiographically appropriate for children aged 3 months to 8 years, whereas simulated CC targeting approximately one-half external AP chest depth seems radiographically to be too deep, resulting in residual internal chest depth of <10 mm for most patients of this age.
