Establishing Outcome Parameters for Helicopter Emergency Medical Services Research in The Netherlands: Results of a Mixed-Methods Delphi Consensus Study.

Objectives: Physician staffed Helicopter Emergency Medical Services (P-HEMS) care in the Netherlands has transitioned from predominantly trauma management to handling a variety of medical conditions. Relevant outcome parameters for Dutch P-HEMS research have not been previously defined. National consensus was sought to identify relevant long term patient outcome parameters, process outcome parameters and performance outcome parameters for Dutch P-HEMS care.

Increased incidence of traumatic spinal injury in patients aged 65 years and older in the Netherlands.

Purpose: The global population is ageing rapidly. As a result, an increasing number of older patients with traumatic spine injuries are seen in hospitals worldwide. However, it is unknown how the incidence of traumatic spinal injury has developed over the past decade.

Missing patient registrations in the Dutch National Trauma Registry of Southwest Netherlands: Prevalence and epidemiology.

Introduction: Health care patient records have been digitalised the past twenty years, and registries have been automated. Missing registrations are common, and can result in selection bias.

Objective: To assess the prevalence and characteristics of missed registrations in a Dutch regional trauma registry.

Clinical outcomes and end-of-life treatment in 596 patients with isolated traumatic brain injury: a retrospective comparison of two Dutch level-I trauma centers.

Purpose: With an increasingly older population and rise in incidence of traumatic brain injury (TBI), end-of-life decisions have become frequent. This study investigated the rate of withdrawal of life sustaining treatment (WLST) and compared treatment outcomes in patients with isolated TBI in two Dutch level-I trauma centers.

Methods: From 2011 to 2016, a retrospective cohort study of patients aged ≥ 18 years with isolated moderate-to-severe TBI (Abbreviated Injury Scale (AIS) head ≥ 3) was conducted at the University Medical Center Rotterdam (UMC-R) and the University Medical Center Utrecht (UMC-U).

Comparing health status after major trauma across different levels of trauma care.

Introduction: Mortality due to trauma has reduced the past decades. Trauma network implementations have been an important contributor to this achievement. Besides mortality, patient reported outcome parameters should be included in evaluation of trauma care.

Impact of the SARS-CoV-2 pandemic on trauma care: a nationwide observational study.

Purpose: The SARS-CoV-2 pandemic severely disrupted society and the health care system. In addition to epidemiological changes, little is known about the pandemic's effects on the trauma care chain. Therefore, in addition to epidemiology and aetiology, this study aims to describe the impact of the SARS-CoV-2 pandemic on prehospital times, resource use and outcome.

Primary admission and secondary transfer of trauma patients to Dutch level I and level II trauma centers: predictors and outcomes.

Purpose: The importance and impact of determining which trauma patients need to be transferred between hospitals, especially considering prehospital triage systems, is evident. The objective of this study was to investigate the association between mortality and primary admission and secondary transfer of patients to level I and II trauma centers, and to identify predictors of primary and secondary admission to a designated level I trauma center.

Methods: Data from the Dutch Trauma Registry South West (DTR SW) was obtained.

Health-related quality of life and return to work 1 year after major trauma from a network perspective.

Introduction: Major trauma often results in long-term disabilities. The aim of this study was to assess health-related quality of life, cognition, and return to work 1 year after major trauma from a trauma network perspective.

Methods: All major trauma patients in 2016 (Injury Severity Score > 15, n = 536) were selected from trauma region Southwest Netherlands.

The definition of major trauma using different revisions of the abbreviated injury scale.

Background: A threshold Injury Severity Score (ISS) ≥ 16 is common in classifying major trauma (MT), although the Abbreviated Injury Scale (AIS) has been extensively revised over time. The aim of this study was to determine effects of different AIS revisions (1998, 2008 and 2015) on clinical outcome measures.

Methods: A retrospective observational cohort study including all primary admitted trauma patients was performed (in 2013-2014 AIS98 was used, in 2015-2016 AIS08, AIS08 mapped to AIS15).

The Relationship between Hospital Volume and In-Hospital Mortality of Severely Injured Patients in Dutch Level-1 Trauma Centers.

Centralization of trauma centers leads to a higher hospital volume of severely injured patients (Injury Severity Score (ISS) > 15), but the effect of volume on outcome remains unclear. The aim of this study was to determine the association between hospital volume of severely injured patients and in-hospital mortality in Dutch Level-1 trauma centers. A retrospective observational cohort study was performed using the Dutch trauma registry.

The association between level of trauma care and clinical outcome measures: A systematic review and meta-analysis.

Background: With implementation of trauma systems, a level of trauma care classification was introduced. Use of such a system has been linked to significant improvements in survival and other outcomes.

Objectives: The aim of this study was assessing the association between level of trauma care and fatal and nonfatal outcome measures for general and major trauma (MT) populations.

Fatigue-related changes in motor-unit synchronization of quadriceps muscles within and across legs.

Two experiments were conducted to examine effects of muscle fatigue on motor-unit synchronization of quadriceps muscles (rectus femoris, vastus medialis, vastus lateralis) within and between legs. We expected muscle fatigue to result in an increased common drive to different motor units of synergists within a leg and, hence, to increased synchronization, i.e.
