Hand hygiene in emergencies: Multiprofessional perceptions from a mixed methods based online survey in Germany

Introduction

Despite high vulnerability to infection, hand disinfection compliance in emergencies is low. This is regularly justified as the disinfection procedure delays life support, and instead, wearing disposable gloves is preferred. Simulation studies showed higher achievable compliance than detected in real-life situations. This study aimed to explore healthcare providers' attitudes toward hand disinfection and using gloves in emergencies.

Methods

We conducted an anonymous online survey in Germany on the attitude and subjective behavior in the five moments of hand hygiene in a closed environment and an open convenience sampling survey. Statistics included paired student's t-tests corrected for multiple testing. For qualitative analysis, we employed a single-coder approach.

Results

In 400 participants, we detected low priority of WHO-1 (before touching a patient) and WHO-2 (before clean/aseptic procedure) hand hygiene moments, despite knowing the risks of omission of hand disinfection. For all moments, self-assessment exceeded the assessment of colleagues (p < 0.001). For WHO-3, we detected a lower disinfection priority for wearing gloves compared to contaminated bare hands. Qualitative analyses revealed five themes: basic conditions, didactic implementations, cognitive load, and uncertainty about feasibility and efficacy.

Discussion

Considering bias, the study's subjective nature, the unknown role of emergency-related infections contributing to hospital-acquired infections, and different experiences of healthcare providers, we conclude that hand disinfection before emergencies is de-prioritized and justified by the emergency situation regardless of the objective feasibility.

Conclusion

This study reveals subjective and objective barriers to implementation of WHO-1 and WHO-2 moments of hand disinfection to be further evaluated and addressed in educational programs.

The effects of bystander interventions for foreign body airway obstruction on survival and neurological outcomes: Findings of the MOCHI registry

INTRODUCTION

Foreign body airway obstruction (FBAO) is a life-threatening condition. We aimed to quantify the impact of bystander FBAO interventions on survival and neurological outcomes.

METHODS

We conducted a Japan-wide prospective, multi-center, observational study including all FBAO patients who presented to the Emergency Department from April 2020 to March 2023. Information on bystander FBAO interventions was collected through interviews with emergency medical services personnel. Primary outcomes included 1-month survival and favorable neurologic outcome defined as Cerebral Performance Category 1 or 2. We performed a multivariable logistic regression and a Cox proportional hazards modeling to adjust for confounders.

RESULTS

We analyzed a total of 407 patients in the registry who had the median age of 82 years old (IQR 73-88). The FBAO incidents were often witnessed (86.5%, n = 352/407) and the witnesses intervened in just over half of the cases (54.5%, n = 192/352). The incidents frequently occurred at home (54.3%, n = 221/407) and nursing home (21.6%, n = 88/407). Common first interventions included suction (24.8%, n = 101/407) and back blow (20.9%, n = 85/407). The overall success rate of bystander interventions was 48.4% (n = 93/192). About half (48.2%, n = 196/407) survived to 1-month and 23.8% patients (n = 97/407) had a favorable neurological outcome. Adjusting for pre-specified confounders, bystander interventions were independently associated with survival (hazard ratio, 0.55; 95% CI, 0.39-0.77) and a favorable neurological outcome (adjusted OR, 2.18; 95% CI, 1.23-3.95).

CONCLUSION

Bystander interventions were independently associated with survival and favorable neurological outcome, however, they were performed only in the half of patients.

Death and Ultrasound Evidence of the Akinetic Heart in Pediatric Cardiac Arrest

Point-of-care ultrasound (POCUS) is an expanding noninvasive diagnostic modality used for the management of patients in multiple intensive care and pediatric specialties. POCUS is used to assess cardiac activity and pathology, pulmonary disease, intravascular volume status, intra-abdominal processes, procedural guidance including vascular access, lumbar puncture, thoracentesis, paracentesis, and pericardiocentesis. POCUS has also been used to determine anterograde flow following circulatory arrest when organ donation after circulatory death is being considered. Published guidelines exist from multiple medical societies including the recent guidelines for the use of POCUS in neonatology for diagnostic and procedural purposes.

Cardiac POCUS in Pediatric Emergency Medicine: A Narrative Review

PURPOSE OF THIS REVIEW

The cardiac point of care ultrasound (POCUS) is among the most impactful examinations in the evaluation of an ill child. This paper will review the English-language literature on cardiac POCUS in the pediatric emergency department (PED), the adult emergency literature with relevance to pediatric emergency, and other pediatric cardiac studies outside pediatric emergency with relevance to PED detection of potentially emergent pediatric cardiac pathology.

RECENT FINDINGS

Pediatric emergency physicians can reliably detect decreased left-sided systolic function and pericardial effusion using POCUS. Case reports show that pediatric emergency physicians have detected right-sided outflow tract obstruction, aortic root dilatation, and congenital cardiac disease using POCUS. Training for pediatric cardiac POCUS competency is feasible, and cardiac POCUS does not increase the burden on cardiology resources to the PED.

SUMMARY

While cardiac pathology in children is relatively rare, pediatric cardiac POCUS can incorporate a broad curriculum beyond systolic function and the presence of pericardial fluid. Further research should assess pediatric emergency physician performance in the identification of a broader range of cardiac pathology.

Optimizing transition: Providing oxygen during intact cord resuscitation

Delayed clamping and cutting of the umbilical cord at birth is standard practice for management for all newborns. Preterm infants may additionally benefit from a combination of ventilation and oxygen provision during intact cord resuscitation. This review highlights both the potential benefits of such a combined approach and the need for further rigorous studies, including randomized controlled trials, of delivery room management in this population.

Food choking incidents in the hospital: incidents, characteristics, effectiveness of interventions, and mortality and morbidity outcomes

AIM

Foreign body airway obstruction (FBAO) due to food can occur wherever people eat, including in hospitals. We characterized in-hospital FBAO incidents and their outcomes.

METHODS

We searched the Japan Council for Quality Health Care nationwide in-hospital adverse events database for relevant events from 1,549 institutions. We included all patients with FBAO incidents due to food in the hospital from January 2010 to June 2021 and collected data on the characteristics, interventions, and outcomes. FBAO from non-food materials were excluded. Our primary outcomes were mortality and morbidity from FBAO incidents.

RESULTS

We identified 300 patients who had a FBAO incident from food. The most common age group was 80 - 89 years old (32.3%, n = 97/300). One-half (50.0%, n = 150/300) were witnessed events. Suction was the most common first intervention (31.3%, n = 94/300) and resulted in successful removal of foreign body in 17.0% of cases (n = 16/94). Back blows (16.0%, n = 48/300) and abdominal thrusts (8.1%, n = 24/300) were less frequently performed as the first intervention and the success rates were 10.4% (n = 5/48) and 20.8% (n = 5/24), respectively. About one-third of the patients (31%, n = 93/300) died and 26.7% (n = 80/300) had a high potential of residual disability from the incidents.

CONCLUSION

FBAO from food in the hospital is an uncommon but life-threatening event. The majority of patients who suffered from the in-hospital FBAO incidents did not receive effective interventions initially and many of them died or suffered residual disability.

Advanced and Invasive Cardiopulmonary Resuscitation (CPR) Techniques as an Adjunct to Advanced Cardiac Life Support

BACKGROUND

Despite numerous promising innovations, the chance of survival from sudden cardiac arrest has remained virtually unchanged for decades. Recently, technological advances have been made, user-friendly portable devices have been developed, and advanced invasive procedures have been described that could improve this unsatisfactory situation.

METHODS

A selective literature search in the core databases with a focus on randomized controlled trials and guidelines.

RESULTS

Technical aids, such as feedback systems or automated mechanical cardiopulmonary resuscitation (CPR) devices, can improve chest compression quality. The latter, as well as extracorporeal CPR, might serve as a bridge to treatment (with extracorporeal CPR even as a bridge to recovery). Sonography may be used to improve thoracic compressions on the one hand and to rule out potentially reversible causes of cardiac arrest on the other. Resuscitative endovascular balloon occlusion of the aorta might enhance myocardial and cerebral perfusion. Minithoracostomy, pericardiocentesis, or clamshell thoracotomy might resolve reversible causes of cardiac arrest.

CONCLUSIONS

It is crucial to identify those patients who may benefit from an advanced or invasive procedure and make the decision to implement the intervention in a timely manner. As with all infrequently performed procedures, sound education and regular training are paramount.

Steroid treatment as anti-inflammatory and neuroprotective agent following out-of-hospital cardiac arrest: a randomized clinical trial

Background

Patients resuscitated from out-of-hospital cardiac arrest (OHCA) have a high morbidity and mortality risk and often develop post-cardiac arrest syndrome (PCAS) involving systemic inflammation. The severity of the inflammatory response is associated with adverse outcome, with anoxic irreversible brain injury as the leading cause of death following resuscitated OHCA. The study aimed to investigate the anti-inflammatory and neuroprotective effect of pre-hospital administration of a high-dose glucocorticoid following OHCA.

Methods

The study is an investigator-initiated, randomized, multicenter, single-blinded, placebo-controlled, clinical trial. Inclusion will continue until one hundred twenty unconscious OHCA patients surviving a minimum of 72 h are randomized. Intervention is a 1:1 randomization to an infusion of methylprednisolone 250 mg following a minimum of 5 min of sustained return of spontaneous circulation in the pre-hospital setting. Methylprednisolone will be given as a bolus infusion of 1 × 250 mg (1 × 4 mL) over a period of 5 min. Patients allocated to placebo will receive 4 mL of isotonic saline (NaCl 0.9%). Main eligibility criteria are OHCA of presumed cardiac cause, age ≥ 18 years, Glasgow Coma Scale ≤ 8, and sustained ROSC for at least 5 min. Co-primary endpoint: Reduction of interleukin-6 and neuron-specific-enolase. Secondary endpoints: Markers of inflammation, brain, cardiac, kidney and liver damage, hemodynamic and hemostatic function, safety, neurological function at follow-up, and mortality. A research biobank is set up with blood samples taken daily during the first 72 h from hospitalization to evaluate primary and secondary endpoints.

Discussion

We hypothesize that early anti-inflammatory steroid treatment in the pre-hospital setting can mitigate the progression of PCAS following resuscitated OHCA. Primary endpoints will be assessed through analyses of biomarkers for inflammation and neurological damage taken during the first 72 h of admission.
