RESUMO
BACKGROUND : Nonmodifiable patient and endoscopy characteristics might influence colonoscopy performance. Differences in these so-called case-mix factors are likely to exist between endoscopy centers. This study aimed to examine the importance of case-mix adjustment when comparing performance between endoscopy centers. METHODS : Prospectively collected data recorded in the Dutch national colonoscopy registry between 2016 and 2019 were retrospectively analyzed. Cecal intubation rate (CIR) and adequate bowel preparation rate (ABPR) were analyzed. Additionally, polyp detection rate (PDR) was studied in screening colonoscopies following a positive fecal immunochemical test (FIT). Variation in case-mix factors between endoscopy centers and expected outcomes for each performance measure were calculated per endoscopy center based on case-mix factors (sex, age, American Society of Anesthesiologist [ASA] score, indication) using multivariable logistic regression. RESULTS: 363â 840 colonoscopies were included from 51 endoscopy centers. Mean percentages per endoscopy center were significantly different for age >â65 years, male patients, ASAâ≥âIII, and diagnostic colonoscopies (all Pâ<â0.001). In the FIT-positive screening population, significant differences were observed between endoscopy centers for age >â65 years, male patients, and ASAâ≥âIII (all Pâ≤â0.001). The expected CIR, ABPR, and PDR ranged from 95.0â% to 96.9â%, from 93.6â% to 96.4â%, and from 76.2â% to 79.1â%, respectively. Age, sex, ASA classification, and indication were significant case-mix factors for CIR and ABPR. In the FIT-positive screening population, age, sex, and ASA classification were significant case-mix factors for PDR. CONCLUSION: Our findings emphasize the importance of considering case-mix adjustment when comparing colonoscopy performance measures between endoscopy centers.

BACKGROUND: Emergency departments (EDs) are faced with a growing number of patients with traumatic brain injury (TBI) using direct oral anticoagulants (DOACs). However, there remains uncertainty about the bleeding risk, rate of hematoma expansion, and the efficacy of reversal strategies in these patients. OBJECTIVE: This study aims to identify the risk of traumatic hemorrhagic complications in patients with TBI using DOACs. METHODS: In this retrospective study we included patients with TBI. All TBI patients were using DOACs, attended one of the three EDs of our hospital between January 2016 and October 2019, and received a computed tomography (CT) scan of the brain. The primary outcome was any traumatic intracranial hemorrhage on CT. Secondary outcomes were the use of reversal agents, secondary neurological deterioration, a neurosurgical intervention within 30 days after the injury, length of stay (LOS), Glasgow Outcome Scale (GOS) at discharge, and mortality. RESULTS: Of the included patients (N = 316), 24 patients (7.6%, 95% confidence interval [CI] 4.2-9.8) presented with a traumatic intracranial hematoma (ICH). Seven patients (2.2%, 95% CI 0.6-3.8) received a reversal agent and 1 patient (0.3%, 95% CI -0.3-0.9) underwent a neurosurgical intervention. Of the 24 patients with a traumatic ICH, progression of the lesion was seen in 6 patients (1.9%, 95% CI 0.4-3.4). The mean LOS was 6.5 days (95% CI 3.0-10.1) and the mean GOS at discharge was 4 (95% CI 3.6-4.6). Death occurred in 1 patient (0.3%, 95% CI -0.3-0.9) suffering from an ICH. CONCLUSION: Based on the present findings it can be postulated that TBI patients using DOACs have a low risk for ICH. Hematoma progression occurred, however, in a substantial number of patients. Considering the retrospective nature of the present study, future prospective trials are needed to confirm this finding.

OBJECTIVE: The biomarker S100B is a sensitive biomarker to detect traumatic intracranial injury in patients mild traumatic brain injury (mTBI). Higher blood values of S100B, resulting in lower specificity and decreased head computed tomography (CT) reduction has been regarded as one of shortcomings in patients over 65 years of age. The purpose of this study was to assess the accuracy of plasma S100B to detect intracranial injury in elderly patients with mTBI. METHODS: A posthoc analysis was performed of a larger prospective cohort study. Previous recorded patient variables and plasma values of S100B from patients with mTBI who presented to the Emergency Department (ED) within 6 h of injury, underwent a head CT and had a blood sample drawn as part of their routine clinical care, were partitioned at 65 years of age. Sensitivity, specificity, negative predictive value, and positive predictive value of plasma S100B for predicting traumatic intracranial lesions on head CT, with a cut-off set at 0.105 µg/L, were calculated. Results were compared with data from an additional systematic review on the accuracy of S100B to detect intracranial injury in elderly patients with mTBI. RESULTS: Data of 240 patients (48.4 %) of 65 years or older were analyzed. Sensitivity and NPV of S100B were 89 % and 86 % respectively, which is lower than among younger patients (both 97 %). The specificity decreased stepwise with older age: 22 %, 18 %, and 5 % for the age groups 65-74, 75-84, and ≥ 85 years old, respectively. The meta-analysis comprised 4 studies and the current study with data from 2166 patients. Pooled data estimated the sensitivity of s100B as 97.4 % (95 % CI 83.3-100 %) and specificity as 17.3 % (95 % CI 9.5-29.3 %) to detect intracranial injury in elderly patients with mTBI. CONCLUSION: The biomarker S100B at the routine threshold has a limited clinical value in the management of elderly mTBI patients mainly due to a poor specificity leading to only a small decrease in head CTs. Alternate cut-off values and combining several plasma biomarkers with clinical variables may be useful strategies to increase the accuracy of S100B in (subgroups of) elderly mTBI patients.

Age is variably described as a minor or major risk factor for traumatic intracranial lesions after head injury. However, at present, no specific CT decision rule is available for elderly patients with minor head injury (MHI). The aims of this prospective multicenter cohort study were to assess the performance of existing CT decision rules for elderly MHI patients and to compare the clinical and CT characteristics of elderly patients with the younger MHI population. Thirty-day mortality between two age groups (cutoff ≥ 60 years), along with clinical and CT characteristics, was evaluated with four CT decision rules: the National Institute for Health and Care Excellence (NICE) guideline, the Canadian CT Head Rule (CCHR), the New Orleans Criteria (NOC), and the CT Head Injury Patients (CHIP) rule. Of the 5517 MHI patients included, 2310 were aged ≥ 60 years. Elderly patients experienced loss of consciousness (17% vs. 32%) and posttraumatic amnesia (23% vs. 31%) less often, but intracranial lesions (13% vs. 10%), neurological deterioration (1.8% vs. 0.2%), and 30-day mortality (2.0% vs. 0.1%) were more frequent than in younger patients (all p < 0.001). Elderly patients with age as their only risk factor showed intracranial lesions in 5% (NOC and CHIP) to 8% (CCHR and NICE) of cases. The sensitivity of decision rules in the elderly patients was 60% (CCHR) to 97% (NOC) when age was excluded as a risk factor. Current risk factors considered when evaluating elderly patients show lower sensitivity to identify intracranial abnormalities, despite more frequent intracranial lesions. Until age-specific CT decision rules are developed, it is advisable to scan every elderly patient with an MHI.
RESUMO
To compare hospitals' hip fracture patient mortality in a quality of care registry, correction for patient characteristics is needed. This study evaluates in 39,374 patients which characteristics are associated with 30 and 90-day mortality, and showed how using these characteristics in a case mix-model changes hospital comparisons within the Netherlands. PURPOSE: Mortality rates after hip fracture surgery are considerable and may be influenced by patient characteristics. This study aims to evaluate hospital variation regarding patient demographics and disease burden, to develop a case-mix adjustment model to analyse differences in hip fracture patients' mortality to calculate case-mix adjusted hospital-specific mortality rates. METHODS: Data were derived from 64 hospitals participating in the Dutch Hip Fracture Audit (DHFA). Adult hip fracture patients registered in 2017-2019 were included. Variation of case-mix factors between hospitals was analysed, and the association between case-mix factors and mortality at 30 and 90 days was determined through regression models. RESULTS: There were 39,374 patients included. Significant variation in case-mix factors amongst hospitals was found for age ≥ 80 (range 25.8-72.1% p < 0.001), male gender (12.0-52.9% p < 0.001), nursing home residents (42.0-57.9% p < 0.001), pre-fracture mobility aid use (9.9-86.7% p < 0,001), daily living dependency (27.5-96.5% p < 0,001), ASA-class ≥ 3 (25.8-83.3% p < 0.001), dementia (3.6-28.6% p < 0.001), osteoporosis (0.0-57.1% p < 0.001), risk of malnutrition (0.0-29.2% p < 0.001) and fracture types (all p < 0.001). All factors were associated with 30- and 90-day mortality. Eight hospitals showed higher and six showed lower 30-day mortality than expected based on their case-mix. Six hospitals showed higher and seven lower 90-day mortality than expected. The specific outlier hospitals changed when correcting for case-mix factors. CONCLUSIONS: Dutch hospitals show significant case-mix variation regarding hip fracture patients. Case-mix adjustment is a prerequisite when comparing hospitals' 30-day and 90-day hip fracture patients' mortality. Adjusted mortality may serve as a starting point for improving hip fracture care.

The aim of this work was to conduct a systematic review and meta-analysis of studies reporting on the risk of traumatic intracerebral hemorrhage (tICH), the course of tICH, and its treatment and mortality rates in elderly mild traumatic brain injury (mTBI) patients using direct oral anticoagulants (DOACs). We consulted PubMed and Embase for relevant cohort and case-control studies with a control group. Two authors independently selected studies, assessed methodological quality, and extracted outcome data. Estimates were pooled with the Mantel-Haenszel random-effects method. We identified 16 articles comprising 3671 elderly mTBI patients using DOACs. Use of DOACs was associated with a reduced risk of tICH compared to the use of vitamin K antagonists (VKAs; odds ratio [OR], 0.44; 95% confidence interval [CI], 0.29-0.65; I2 = 22%) and a similar risk compared to the use of antiplatelet therapy (APT; OR, 0.98; 95% CI, 0.39-2.44; I2 = 0%). Reversal agent use and neurosurgical intervention rate were lower in patients using DOACs compared to patients using VKAs (OR, 0.10; 95% CI, 0.06-0.16; I2 = 0% and OR, 0.37; 95% CI, 0.21-0.67; I2 = 0%, respectively). There was no significant difference in neurosurgical intervention rate between patients who used DOACs versus patients who used APT (OR, 0.58; 95% CI, 0.15-2.21; I2 = 41%) or no antithrombotic therapy (OR, 0.76; 95% CI, 0.20-2.86; I2 = 23%). ICH progression, risk of delayed ICH, and TBI-related in-hospital mortality were comparable among treatment groups. The present study indicates that elderly patients using DOACs have a lower risk of adverse outcome compared to patients using VKAs and a similar risk compared to patients using APT after mTBI.

BACKGROUND: The Dutch Surgical Aneurysm Audit (DSAA) is a nationwide mandatory quality registry that evaluates the perioperative outcomes of abdominal aortic aneurysms (AAAs). The DSAA includes perioperative outcomes that occur up to 30 days, but various complications following AAA repair occur after this period. Administrative healthcare data yield the possibility to evaluate later occuring outcomes such as reinterventions, without increasing the registration burden. The aim of this study is to assess the feasibility and the potential benefit of administrative healthcare data to evaluate mid-term reinterventions following intact AAA repair. METHOD: All patients that underwent primary endovascular aneurysm repair (EVAR) or open surgical repair (OSR) for an intact infrarenal AAA between January 2017 and December 2018 were selected from the DSAA. Subsequently, these patients were identified in a database containing reimbursement data. Healthcare activity codes that refer to reinterventions following AAA repair were examined to assess reinterventions within 12 and 15 months following EVAR and OSR. RESULTS: We selected 4043 patients from the DSAA, and 2059 (51%) patients could be identified in the administrative healthcare database. Reintervention rates of 10.4% following EVAR and 9.5% following OSR within 12 months (p = 0.719), and 11.5% following EVAR and 10.8% following OSR within 15 months (p = 0.785) were reported. CONCLUSION: Administrative healthcare data as an addition to the DSAA is potentially beneficial to evaluate mid-term reinterventions following intact AAA repair without increasing the registration burden for clinicians. Further validation is necessary before reliable implementation of this tool is warranted.

OBJECTIVE: To update the existing CHIP (CT in Head Injury Patients) decision rule for detection of (intra)cranial findings in adult patients following minor head injury (MHI). METHODS: The study is a prospective multicenter cohort study in the Netherlands. Consecutive MHI patients of 16 years and older were included. Primary outcome was any (intra)cranial traumatic finding on computed tomography (CT). Secondary outcomes were any potential neurosurgical lesion and neurosurgical intervention. The CHIP model was validated and subsequently updated and revised. Diagnostic performance was assessed by calculating the c-statistic. RESULTS: Among 4557 included patients 3742 received a CT (82%). In 383 patients (8.4%) a traumatic finding was present on CT. A potential neurosurgical lesion was found in 73 patients (1.6%) with 26 (0.6%) patients that actually had neurosurgery or died as a result of traumatic brain injury. The original CHIP underestimated the risk of traumatic (intra)cranial findings in low-predicted-risk groups, while in high-predicted-risk groups the risk was overestimated. The c-statistic of the original CHIP model was 0.72 (95% CI 0.69-0.74) and it would have missed two potential neurosurgical lesions and one patient that underwent neurosurgery. The updated model performed similar to the original model regarding traumatic (intra)cranial findings (c-statistic 0.77 95% CI 0.74-0.79, after crossvalidation c-statistic 0.73). The updated CHIP had the same CT rate as the original CHIP (75%) and a similar sensitivity (92 versus 93%) and specificity (both 27%) for any traumatic (intra)cranial finding. However, the updated CHIP would not have missed any (potential) neurosurgical lesions and had a higher sensitivity for (potential) neurosurgical lesions or death as a result of traumatic brain injury (100% versus 96%). CONCLUSIONS: Use of the updated CHIP decision rule is a good alternative to current decision rules for patients with MHI. In contrast to the original CHIP the update identified all patients with (potential) neurosurgical lesions without increasing CT rate.

When acute stroke care is organised using a "drip-and-ship" model, patients receive immediate treatment at the nearest primary stroke centre followed by transfer to a comprehensive stroke centre (CSC). When stroke care is further centralised into the "direct-to-mothership" model, patients with stroke symptoms are immediately brought to a CSC to further reduce treatment times and enhance stroke outcomes. We investigated the effects of the ongoing centralization in a Dutch urban setting on treatment times of patients with confirmed ischemic stroke in a 4-year period. Next, in a non-randomized controlled trial, we assessed treatment times of patients with suspected ischemic stroke, and treatment times of patients with neurologic disorders other than suspected ischemic stroke, before and after the intervention in the CSC and the decentralized hospitals, the intervention being the change from "drip and ship" into "direct-to-mothership". Our findings provide support for the ongoing centralization of acute stroke care in urban areas. Treatment times for patients with ischemic stroke decreased significantly, potentially improving functional outcomes. Improvements in treatment times for patients with suspected ischemic stroke were achieved without negative side effects for self-referrals with stroke symptoms and patients with other neurological disorders.

Emergency departments (EDs) are eerily quiet for illnesses apart from COVID-19. In this short communication, we assessed the effect of COVID-19 on ED attendance rates for traumatic brain injury (TBI). Data were collected from all consecutive patients with TBI attending our hospital (Haaglanden Medical Center, The Hague, The Netherlands) during the first 3 weeks of the Dutch lockdown (from March 18 to April 6) and for the same period last year. We observed a 36% decrease in ED attendance for TBI since the beginning of the SARS-CoV-2 pandemic (91 vs. 143). Patients who presented during the lockdown were significantly older compared with the patients who visited the ED in the previous year (72 vs. 57, p = 0.01). No other significant differences were found.
RESUMO
OBJECTIVE: A new nationwide guideline for minor head injury was introduced in the Netherlands in 2010. The effect on computed tomography (CT) ratio and hospital admission ratio after introduction of the guideline is unknown. The aim was to reduce these numbers as part of cost-effective health care. Therefore, we assessed the effect on these variables after introduction of the guideline. METHODS: We used an interrupted time-series study design. Data selection was done 3 years before (2007-2009) and several years after (2012, 2014, 2015) introduction of the guideline. RESULTS: Data collection was performed for 3880 patients. Introduction of the new guideline was associated with an increase in CT ratio from 24.6% before to 55% after introduction (P < 0.001). This increase is the result of both the new guideline and a secular trend. Besides this, hospital admissions increased from 14.7 to 23.4% (P < 0.001) during the study period. This increase was less clearly associated with the new guideline. After introduction of the guideline there was no significant difference in (intra)cranial traumatic findings (2.6% vs. 3.4%; P = 0.13) and neurosurgical interventions (0.1% vs. 0.2%; P = 0.50). CONCLUSION: Between 2007 and 2015, a marked increase in CT ratio and hospital admissions has been observed. The increase in CT ratio seems to be caused both by the new guideline and by a secular trend to perform more CT scans. Adaptations to the guideline should be considered to improve patient care and cost-effectiveness in patients with minor head injury.

OBJECTIVES: Emergency medicine (EM) in the Netherlands has developed rapidly and initially without central guidance. This has led to heterogeneity in current EM practice. Our aim was to quantify this heterogeneity by answering the following questions: (1) What is the current position of emergency physicians (EPs) within hospital organizations? (2) Which roles and responsibilities do EPs have across emergency departments (EDs)? METHODS: During 2018, we conducted a survey among all EM consultant bodies (CBs, n = 56) in the Netherlands. Data was analyzed using descriptive statistics. RESULTS: The response rate was 91.1%. Presence of EPs has been realized 24/7 in 23.1% of EDs. EPs were the main consultants for all ED patients in 9.8% of CBs, but never had this role in 13.7% of CBs. EPs supervised EM junior doctors in 78.5% of EDs, GPs in training in 80.0% of EDs, and junior doctors of other specialties in 41.5% of EDs. Procedures such as lumbar puncture (LP), procedural sedation and analgesia (PSA), and emergency ultrasound (US) were performed by all EPs in the CB in a range between 5.9 and 78.4%. In 36.9% of EDs, EPs did not analyze patients with presumed cardiac pathology due to a separate First Heart Aid. CONCLUSION: We conclude that there is a high degree of heterogeneity between emergency CBs in regard to the position in the hospital and the role or responsibilities in the ED. Lack of uniformity might inhibit emancipation of the profession.
RESUMO
The aim of this study was to determine the association between bicycle helmet use in adults (16 years and older) and traumatic brain injury (TBI) in emergency departments (EDs) in the Netherlands.The conducted research was a retrospective case-control study in patients aged 16 years and older who sustained a bicycle accident and therefore visited the EDs of participating hospitals throughout 2016. Cases were patients with TBI; controls were patients without TBI but with other trauma. Exposure was defined as helmet wearing during the accident. In total, 2133 patients were included in the study, 361 case patients and 1772 controls. Within the TBI group (cases) 3.9% of patients wore a helmet compared with 7.7% of patients in the control (non-head injury) group (odds ratio [OR] 0.49, 95% confidence interval [CI]: 0.28-0.86). No difference in helmet wearing was observed in patients who sustained accidents that involved motorized vehicles (OR 0.91; 95% CI: 0.29-2.83). In conclusion, adult patients (≥16 years of age) with TBI had a significantly lower odds of wearing a bicycle helmet than adult patients with other trauma, adding more evidence that wearing a bicycle helmet effectively protects against TBI.
RESUMO
BACKGROUND: Over the past two decades, several quality improvement projects have been implemented in emergency departments (EDs) in the Netherlands, one of these being the training and deployment of emergency physicians. In this study we aim to perform a trend analysis of ED quality of care in Dutch hospitals, as measured by the incidence of medical malpractice claims. PATIENTS AND METHODS: We performed a multicentre retrospective cohort study of malpractice claims in five Dutch EDs over the period 1998-2014. Incidence risk ratios were calculated to demonstrate any relation of specific quality improvement initiatives with the primary outcome, defined as the number of claims per 10 000 ED visits per year. RESULTS: During the study period, the cumulative number of ED visits increased significantly from 99 145 in 1998 to 162 490 in 2014 (P < 0.01). In total, 228 of 2 348 417 ED visits (0.97 per 10 000) resulted in a malpractice claim. At the same time, the yearly number of ED claims filed decreased with 0.07 (0.03-0.10) per 10 000 each year. The claim rate was higher in the period before emergency physicians were employed in the ED [1.18 (0.98-1.41) claims per 10 000 visits] compared with the period after they were employed [0.81 (0.67-0.97), incidence risk ratio 0.69 (0.53-0.89), P < 0.01]. CONCLUSION: Even though the number of ED visits increased significantly over the past two decades, the number of malpractice claims filed after an ED visit decreased. Various quality improvement initiatives, including the training and employment of emergency physicians, may have contributed to the observed decrease in claims.

OBJECTIVE: The aim of this study was to describe the impact of additional medical specialists, non-emergency physicians (non-EPs), performing direct supervision or a combination of direct and indirect supervision at an EP-led emergency department (ED), on patient flow and satisfaction. PATIENTS AND METHODS: An observational, cross-sectional, three-part study was carried out including staff surveys (n=379), a before and after 16-week data collection using data of visits during the peak hours (n=5270), and patient questionnaires during 1 week before the pilot and during week 5 of the pilot. Content analysis and descriptive statistics were used for analyses. RESULTS: The value of being present at the ED was acknowledged by medical specialists in 49% of their surveys and 35% of the EPs' and ED nurses' surveys, especially during busy shifts. Radiologists were most often (67.3%) convinced of their value of being on-site, which was agreed upon by the ED professionals. Perceived improved quality of care, shortening of length of stay, and enhanced peer consultation were mentioned most often.During the pilot period, length of stay of boarded patients decreased from 197 min (interquartile range: 121 min) to 181 min (interquartile range: 113 min, P=0.006), and patient recommendation scores increased from -15 to +20. CONCLUSION: Although limited by the mix of direct and indirect supervision, our results suggest a positive impact of additional medical specialists during busy shifts. Throughput of admitted patients and patient satisfaction improved during the pilot period. Whether these findings differ between direct supervision and combination of direct and indirect supervision by the medical specialists requires further investigation.

Various guidelines for minor head injury focus on patients with a Glasgow Coma Scale (GCS) score of 13-15 and loss of consciousness (LOC) or post-traumatic amnesia (PTA), while clinical management for patients without LOC or PTA is often unclear. We aimed to investigate the effect of presence and absence of LOC or PTA on intracranial complications in minor head injury. A prospective multi-center cohort study of all patients with blunt head injury and GCS score of 15 was conducted at six Dutch centers between 2015 and 2017. Five centers used the national guideline and one center used a local guideline-both based on the CT in Head Injury Patients (CHIP) prediction model-to identify patients in need of a computed tomography (CT) scan. We studied the presence of traumatic findings and neurosurgical interventions in patients with and without LOC or PTA. In addition, we assessed the association of LOC and PTA with traumatic findings with logistic regression analysis and the additional predictive value of LOC and PTA compared with other risk factors in the CHIP model. Of 3914 patients, 2249 (58%) experienced neither LOC nor PTA and in 305 (8%) LOC and PTA was unknown. Traumatic findings were present in 153 of 1360 patients (11%) with LOC or PTA and in 67 of 2249 patients (3%) without LOC and PTA. Five patients without LOC and PTA had potential neurosurgical lesions and one patient underwent a neurosurgical intervention. LOC and PTA were strongly associated with traumatic findings on CT, with adjusted odds ratios of 2.9 (95% confidence interval [CI] 2.2-3.8) and 3.5 (95% CI 2.7-4.6), respectively. To conclude, patients who had minor head injury with neither LOC nor PTA are at risk of intracranial complications. Clinical guidelines should include clinical management for patients without LOC and PTA, and they should include LOC and PTA as separate risk factors rather than as diagnostic selection criteria.

BACKGROUND: Emergency departments (EDs) worldwide face crowding, which hampers patient flow. In this study, the impact of a dedicated neurologist present at the ED on patient flow during out-of-office hours was assessed. METHODS: A cross-sectional, mixed methods study was undertaken at a Dutch ED, including a pre-post analysis of data of patients who had a primary neurological disease (n = 458) and staff surveys (n = 152). Descriptive statistics and content analysis were used for analyses. RESULTS: Despite a 36% increase in the number of neurological patients (control period: n = 194, intervention period n = 264), a 30 min per patient decrease in ED median length of stay (LOS) was reached during the intervention period. Furthermore, the admission percentage decreased significantly (57.7% in the control period vs. 47.7% in the intervention period, p = 0.03). During half of the shifts neurologists stated that their presence had been valuable. Perceived reasons for this added value mentioned were improved quality of care, enhanced throughput of patients, and quicker consultations with other medical specialists. CONCLUSIONS: In our hypothesis-generating study, a dedicated neurologist present at the ED during out-of-office hours was associated with decreased patients' LOS and a decreased admission percentage, indicating increased decisiveness when the neurologist is present at the ED.

BACKGROUND: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide. The effects of epidemiological changes such as ageing of the population and increased traffic safety on the incidence of TBI are unknown. OBJECTIVE: The objective of this study was to evaluate trends in TBI-related emergency department (ED) visits, hospitalization and mortality in the Netherlands between 1998 and 2012. DESIGN: This was a retrospective observational, longitudinal study. MAIN OUTCOME MEASURES: The main outcome measures were TBI-related ED visits, hospitalization and mortality. RESULTS: Between 1998 and 2012, there were 500 000 TBI-related ED visits in the Netherlands. In the same period, there were 222 000 TBI-related admissions and 17 000 TBI-related deaths. During this period, there was a 75% increase in ED visits for TBI and a 95% increase for TBI-related hospitalization; overall mortality because of TBI did not change significantly. Despite the overall increase in TBI-related ED visits, this increase was not evenly distributed among age groups or trauma mechanisms. In patients younger than 65 years, a declining trend in ED visits for TBI caused by road traffic accidents was observed. Among patients 65 years or older, ED visits for TBI caused by a fall increased markedly. TBI-related mortality shifted from mainly young (67%) and middle-aged individuals (<65 years) to mainly elderly (63%) individuals (≥65 years) between 1998 and 2012. The conclusions of this study did not change when adjusting for changes in age, sex and overall population growth. CONCLUSION: The incidence of TBI-related ED visits and hospitalization increased markedly between 1998 and 2012 in the Netherlands. TBI-related mortality occurred at an older age. These observations are probably the result of a change in aetiology of TBI, specifically a decrease in traffic accidents and an increase in falls in the ageing population. This hypothesis is supported by our data. However, ageing of the population is not the only cause of the changes observed; the observed changes remained significant when correcting for age and sex. The higher incidence of TBI with a relatively stable mortality rate highlights the importance of clinical decision rules to identify patients with a high risk of poor outcome after TBI.

OBJECTIVE: To externally validate four commonly used rules in computed tomography (CT) for minor head injury. DESIGN: Prospective, multicentre cohort study. SETTING: Three university and six non-university hospitals in the Netherlands. PARTICIPANTS: Consecutive adult patients aged 16 years and over who presented with minor head injury at the emergency department with a Glasgow coma scale score of 13-15 between March 2015 and December 2016. MAIN OUTCOME MEASURES: The primary outcome was any intracranial traumatic finding on CT; the secondary outcome was a potential neurosurgical lesion on CT, which was defined as an intracranial traumatic finding on CT that could lead to a neurosurgical intervention or death. The sensitivity, specificity, and clinical usefulness (defined as net proportional benefit, a weighted sum of true positive classifications) of the four CT decision rules. The rules included the CT in head injury patients (CHIP) rule, New Orleans criteria (NOC), Canadian CT head rule (CCHR), and National Institute for Health and Care Excellence (NICE) guideline for head injury. RESULTS: For the primary analysis, only six centres that included patients with and without CT were selected. Of 4557 eligible patients who presented with minor head injury, 3742 (82%) received a CT scan; 384 (8%) had a intracranial traumatic finding on CT, and 74 (2%) had a potential neurosurgical lesion. The sensitivity for any intracranial traumatic finding on CT ranged from 73% (NICE) to 99% (NOC); specificity ranged from 4% (NOC) to 61% (NICE). Sensitivity for a potential neurosurgical lesion ranged between 85% (NICE) and 100% (NOC); specificity from 4% (NOC) to 59% (NICE). Clinical usefulness depended on thresholds for performing CT scanning: the NOC rule was preferable at a low threshold, the NICE rule was preferable at a higher threshold, whereas the CHIP rule was preferable for an intermediate threshold. CONCLUSIONS: Application of the CHIP, NOC, CCHR, or NICE decision rules can lead to a wide variation in CT scanning among patients with minor head injury, resulting in many unnecessary CT scans and some missed intracranial traumatic findings. Until an existing decision rule has been updated, any of the four rules can be used for patients presenting minor head injuries at the emergency department. Use of the CHIP rule is recommended because it leads to a substantial reduction in CT scans while missing few potential neurosurgical lesions.

OBJECTIVES: Emergency medicine is a fast-growing medical profession. Nevertheless, the clinical activities emergency physicians (EPs) carry out and the responsibilities they have differ considerably between hospitals. This article addresses the question how the role of EPs is shaped and institutionalized in the everyday context of acute care in hospitals. METHODS: A cross-case ethnographic study was conducted, comprising observations, document analysis, and in-depth interviews in three emergency departments in the Netherlands. RESULTS: Drawing on the theoretical concept of institutional work, we show that managers, already established medical specialties, and EPs all conduct institutional work to enhance private interests, which both restricts and enlarges EPs' work domain. These actions are strategic and intentional, as well as unintentional and part of EPs' everyday work in acute care delivery. It is in this very process that tasks and responsibilities are redistributed and the role of the EP is shaped. DISCUSSION: In contemporary literature it is often argued that the role and status of EPs should be enhanced by strengthening regulation and improving training programs. This article shows that attention should also be paid to the more subtle everyday processes of role development.
