Multicenter validation of secondary hemophagocytic lymphohistiocytosis diagnostic criteria.

Background: Five fulfilled hemophagocytic lymphohistiocytosis (HLH)-2004 criteria, and the HScore are widely used and recommended by international expert consensus to diagnose secondary HLH. Both diagnostic scores have never been validated in heterogeneous patient cohorts of secondary HLH patients. We aimed to systematically optimize and validate diagnostic criteria of secondary HLH using a multicenter approach.

User Experience Design for Intensive Care Alarm Management.

Alarm fatigue is a pressing issue in intensive care units. Based on user experience design, including clinical shadowings and feedback loops, we developed a prototype for a redesigned patient monitor: The prototype moves away from today's threshold-based alarm systems. It combines a sleek design with machine learning driven clinical insights to mitigate alarm fatigue.

Person-centred decisions in emergency care for older people living with frailty: principles and practice.

Older people living with frailty are frequent users of emergency care and have multiple and complex problems. Typical evidence-based guidelines and protocols provide guidance for the management of single and simple acute issues. Meanwhile, person-centred care orientates interventions around the perspectives of the individual.

The effect of consultations performed by specialised nurses or advanced nurse practitioners on patient and organisational outcomes in patients with complex health conditions: An umbrella review.

Background: Policymakers and researchers often suggest that nurses may play a crucial role in addressing the evolving needs of patients with complex conditions, by taking on advanced roles and providing nursing consultations. Nursing consultations vary widely across settings and countries, and their activities range from complementing to substituting traditional physician-led consultations or usual care.

Objective: This study was aimed at describing the effects of nursing consultations with patients with complex conditions in any setting on patient outcomes (quality of life, physical status, psychosocial health, health behaviour, medication adherence, mortality, anthropometric and physiological outcomes, and patient satisfaction) and organisational outcomes (health resource use and costs).

Core requirements of frailty screening in the emergency department: an international Delphi consensus study.

Introduction: Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study.

Value of hemophagocytosis in the diagnosis of hemophagocytic lymphohistiocytosis in critically ill patients.

Background: Ferritin is an established biomarker in the diagnosis of secondary hemophagocytic lymphohistiocytosis (HLH), which is diagnosed by the HLH-2004 criteria. Among these criteria, detection of hemophagocytosis through invasive procedures may delay early life saving treatment. Our aim was to investigate the value of hemophagocytosis in diagnosing HLH in critically ill patients.

Identifying key items to be addressed by non-clinical operators to manage out-of-hours telephone triage services for older adults seeking non-urgent unplanned care in Belgium: an e-Delphi study.

Background: This study aimed to achieve expert consensus regarding key items to be addressed by non-clinical operators using computer-software integrated medical dispatch protocols to manage out-of-hours telephone triage (OOH-TT) services for calls involving older adults seeking non-urgent unplanned care across Belgium.

Methods: A three-part classic e-Delphi study was conducted. A purposive sample of experts specialized in out-of-hours unplanned care and/or older persons across Belgium were recruited as panelists.

A consensus statement on minimum operational standards for geriatric emergency care in Belgium: a modified Delphi study.

Background: As emergency department (ED) leaders started integrating geriatric emergency guidelines on a facultative basis, important variations have emerged between EDs in care for older patients. The aim of this study was to establish a consensus on minimum operational standards for Geriatric ED care in Belgium.

Methods: A two-stage modified Delphi study was conducted.

A survey on the availability of geriatric-friendly protocols, equipment and physical environment across emergency departments in Flanders, Belgium.

Background: The acquisition of geriatric-friendly resources is an important part of adapting emergency department (ED) care to the needs of vulnerable older patients. The aim of this study was to explore the availability of geriatric-friendly protocols, equipment and physical environment criteria in EDs and to identify related improvement opportunities.

Methods: The head nurse of 63 EDs in Flanders and Brussels Capital Region was invited to complete a survey in collaboration with the chief physician of the ED.

A Standardized Clinical Data Harmonization Pipeline for Scalable AI Application Deployment (FHIR-DHP): Validation and Usability Study.

Background: Increasing digitalization in the medical domain gives rise to large amounts of health care data, which has the potential to expand clinical knowledge and transform patient care if leveraged through artificial intelligence (AI). Yet, big data and AI oftentimes cannot unlock their full potential at scale, owing to nonstandardized data formats, lack of technical and semantic data interoperability, and limited cooperation between stakeholders in the health care system. Despite the existence of standardized data formats for the medical domain, such as Fast Healthcare Interoperability Resources (FHIR), their prevalence and usability for AI remain limited.

Differential Diagnosis of Hyperferritinemia in Critically Ill Patients.

Background: Elevated serum ferritin is a common condition in critically ill patients. It is well known that hyperferritinemia constitutes a good biomarker for hemophagocytic lymphohistiocytosis (HLH) in critically ill patients. However, further differential diagnoses of hyperferritinemia in adult critically ill patients remain poorly investigated.

MIMIC-IV as a Clinical Data Schema.

Routinely collected electronic health records (EHR) in clinical information systems (CIS) are often heterogeneous, have inconsistent data formats and lack of documentation. We use the well-known open-source database schema of MIMIC-IV to address this issue aiming to support collaborative secondary analysis. Over 154 million data records from a German ICU have already been mapped and inserted into the schema successfully.

Utilizing Intensive Care Alarms for Machine Learning.

Alarms help to detect medical conditions in intensive care units and improve patient safety. However, up to 99% of alarms are non-actionable, i.e.

Providing care for older adults in the Emergency Department: expert clinical recommendations from the European Task Force on Geriatric Emergency Medicine.

Purpose: Despite the rapidly expanding knowledge in the field of Geriatric Emergency Medicine in Europe, widespread implementation of change is still lacking. Many opportunities in everyday clinical care are missed to improve care for this susceptible and growing patient group. The aim was to develop expert clinical recommendations on Geriatric Emergency Medicine to be disseminated across Europe.

Influence of transfusions, hemodialysis and extracorporeal life support on hyperferritinemia in critically ill patients.

Background: Ferritin is the major iron storage protein and an acute phase reactant. Hyperferritinemia is frequently seen in the critically ill where it has been hypothesized that not only underlying conditions but also factors such as transfusions, hemodialysis and extracorporeal life support (ECLS) lead to hyperferritinemia. This study aims to investigate the influence of transfusions, hemodialysis, and ECLS on hyperferritinemia in a multidisciplinary ICU cohort.

Patient Monitoring Alarms in an Intensive Care Unit: Observational Study With Do-It-Yourself Instructions.

Background: As one of the most essential technical components of the intensive care unit (ICU), continuous monitoring of patients' vital parameters has significantly improved patient safety by alerting staff through an alarm when a parameter deviates from the normal range. However, the vast number of alarms regularly overwhelms staff and may induce alarm fatigue, a condition recently exacerbated by COVID-19 and potentially endangering patients.

Objective: This study focused on providing a complete and repeatable analysis of the alarm data of an ICU's patient monitoring system.

Consistency of decision support software-integrated telephone triage and associated factors: a systematic review.

Background: In the recent decades, the use of computerized decision support software (CDSS)-integrated telephone triage (TT) has become an important tool for managing rising healthcare demands and overcrowding in the emergency department. Though these services have generally been shown to be effective, large gaps in the literature exist with regards to the overall quality of these systems. In the current systematic review, we aim to document the consistency of decisions that are generated in CDSS-integrated TT.

Structure and processes of emergency observation units with a geriatric focus: a scoping review.

Background: Combining observation principles and geriatric care concepts is considered a promising strategy for risk-stratification of older patients with emergency care needs. We aimed to map the structure and processes of emergency observation units (EOUs) with a geriatric focus and explore to what extent the comprehensive geriatric assessment (CGA) approach was implemented in EOUs.

Methods: The revised scoping methodology framework of Arksey and O'Malley was applied.

A European Research Agenda for Geriatric Emergency Medicine: a modified Delphi study.

Purpose: Geriatric Emergency Medicine (GEM) focuses on delivering optimal care to (sub)acutely ill older people. This involves a multidisciplinary approach throughout the whole healthcare chain. However, the underpinning evidence base is weak and it is unclear which research questions have the highest priority.

Hemophagocytic lymphohistiocytosis in critically ill patients: diagnostic reliability of HLH-2004 criteria and HScore.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare though often fatal hyperinflammatory syndrome mimicking sepsis in the critically ill. Diagnosis relies on the HLH-2004 criteria and HScore, both of which have been developed in pediatric or adult non-critically ill patients, respectively. Therefore, we aimed to determine the sensitivity and specificity of HLH-2004 criteria and HScore in a cohort of adult critically ill patients.
