Brain death is the irreversible loss of brain function necessary to sustain life. Its diagnosis is based on the absence of brainstem reflexes, unresponsiveness to endo- or exogenous stimuli, apnea, and the exclusion of factors confounding the clinical presentation(4). While other organ functions may be preserved, the identification of brain death raises the question of whether viable organs can and should be transplanted to save the lives of critically ill patients in need of organ support.

 

With advancements in critical care techniques enabling the maintenance of organ function beyond brain death, as well as the intricate legal and regulatory frameworks surrounding organ donation, healthcare professionals in intensive care units are increasingly faced with complex clinical scenarios, considerations, and challenges related to the concept and diagnosis of brain death and ethical and legal aspects associated with organ donation. Studies investigating the individual conceptual understanding of brain death and organ donation of health care professionals on Intensive Care Units (ICUs) as well as their experiences and opinions related to these topics, are scarce(5-8).

 

The study aims to gather information regarding the individual perceptions, opinions, beliefs, and conceptual understanding of healthcare professionals working in the intensive care units at the University Hospital Basel and to determine associations of individual beliefs, personal, educational, and professional experiences with individual perceptions, opinions, and conceptual understanding regarding brain death and organ donation. 

To achieve the study objectives, we will employ a questionnaire-based survey administered to the consenting/participating nurses and physicians. The questionnaire will address various aspects related to personal background, religious affiliation, beliefs about life after death, the conceptual understanding of brain death and organ donation, as well as experiences and opinions related to these topics.

Participating in this study will create no additional risk or burden for patients and is therefore classified under category A according to HRO Art. 7.(1)

Hypothesis and primary objective

The primary objective of this study is to gather insights into the individual perceptions, opinions, beliefs, and conceptual understanding regarding brain death and organ donation of healthcare professionals working in the ICU at the University Hospital Basel in Switzerland. 

The following hypotheses will be tested: Individual perceptions, opinions, beliefs, and conceptual understanding regarding brain death and organ donation vary between the different professions and in dependence of specific aspects regarding personal, educational and professional experiences.

Primary and secondary endpoints

The primary endpoints of this study will be information on individual perceptions, opinions, beliefs, and conceptual understanding of healthcare professionals in the ICU regarding brain death and organ donation and the identification ofinterprofessional variations.

The secondary endpoints will be associations of specific demographics, beliefs, personal, educational, social and professional experiences with individual perceptions, opinions, and conceptual understanding regarding brain death and organ donation.

Brief Summary

The aim of the study is to verify the reliability of the current purely clinical examination of the pupils (without the support of a pupillometer) in the context of clinically suspected brain death, compared to the results of a non-invasive, automated, and highly precise monocular pupillometric examination.

Detailed Description

This prospective quality control study will evaluate the reliability of the clinical exam regarding pupils' reaction to light (as performed by two board certified physicians in Neurology and/or Intensive Care Medicine) as recommended by the SAMW guidelines for brain death diagnosis (SAMW-guidelines) when compared to the results of a noninvasive automated and highly-precise pupillometry in adult patients with clinically suspected brain death. Automated pupillometric measurements will be performed by the PI (RS), or the co-investigator (Dr. Pascale Grzonka) using the NeurOptics® NPi®-200 pupillometer system immediately before and after the standardized diagnostic workup for suspected brain death. In addition, demographics, clinical characteristics , treatment and laboratory data from the patients examined will be anonymously collected.

Brief Summary

In the trial the effectiveness of pre-briefing physicians with the current guideline on Status epilepticus (SE) treatment or a consolidated "one page" guideline regarding quality enhancement of the physician's clinical performances is investigated.

Detailed Description

Status epilepticus (SE) is a life-threatening neurological emergency defined as a state of continuous seizure or multiple seizures without full recovery of sensory, motor and/or cognitive function for at least 30 minutes. To achieve high quality management of SE, the American Epilepsy Society published an evidence-based guideline for the treatment of SE, which serves as reference for most national guidelines, but analyses regarding practicability, strict adherence, correct translation into clinical practice, and identification of recommended treatment steps at risk of being modified or missed are lacking. Simulator-based studies offer a platform for the design of standardized clinical scenarios that enable detailed investigations regarding the effect of the implementation and practicability of treatment guidelines.

This randomized controlled intervention study performed at the simulation center of the medical intensive care units (ICUs) at the University Hospital Basel is to investigate the effectiveness of pre-briefing physicians with both the current guideline on Status epilepticus (SE) treatment or a consolidated "one page" guideline regarding quality enhancement of the physicians' clinical performances..

Physicians from different medical specialties and with different duration of clinical experience will be enrolled. Participants will be randomly assigned to one of the following three pre-briefing groups: (1) no pre-briefing prior to the simulation training; (2) pre-briefing with the current SE treatment guidelines; (3) pre-briefing with the consolidated "one page" SE treatment guideline.

Use of antibiotics, drugs to cure bacterial infections, has repeatedly been associated with the occurrence of epileptic seizures (abnormal activity in the brain affecting a person's behavior, consciousness or appearance). Various types of antibiotics have been associated with different risks of epileptic seizures. Generally, the risk of epileptic seizure seems to be highest when high doses of antibiotics are used (for example in hospital), or when patients have impaired kidney function, brain disorders, fever, brain infections, or infections in which bacteria are distributed throughout the body. However, it is not clear whether antibiotics are associated with an increased risk of epileptic seizures when taken at usual outpatient (prescribed by the general practitioner) doses. The goal of this study is to quantify the risk of new-onset epileptic seizures in children and adult patients who are newly prescribed oral (taken by mouth) antibiotics by a general practitioner. We further plan to investigate the potential roles of the type of antibiotic, the antibiotic dose, the patients' age, kidney function, underlying type of infection, and pre-existing drug dependence, metabolic disturbances, or brain disorders.
