Scand J Trauma Resusc Emerg Med 2023; 31:50. [PMID: 37752614 PMCID: PMC10521548 DOI: 10.1186/s13049-023-01118-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 09/10/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND The Norwegian Trauma Registry (NTR) is designed to monitor and improve the quality and outcome of trauma care delivered by Norwegian trauma hospitals. Patient care is evaluated through specific quality indicators, which are constructed of variables reported to the registry by certified registrars. Having high-quality data recorded in the registry is essential for the validity, trust and use of data. This study aims to perform a data quality check of a subset of core data elements in the registry by assessing agreement between data in the NTR and corresponding data in electronic patient records (EPRs). METHODS We validated 49 of the 118 variables registered in the NTR by comparing those with the corresponding ones in electronic patient records for 180 patients with a trauma diagnosis admitted in 2019 at eight public hospitals. Agreement was quantified by calculating observed agreement, Cohen's Kappa and Gwet's first agreement coefficient (AC1) with 95% confidence intervals (CIs) for 27 nominal variables, quadratic weighted Cohen's Kappa and Gwet's second agreement coefficient (AC2) for five ordinal variables. For nine continuous, one date and seven time variables, we calculated intraclass correlation coefficient (ICC). RESULTS Almost perfect agreement (AC1 /AC2/ ICC > 0.80) was observed for all examined variables. Nominal and ordinal variables showed Gwet's agreement coefficients ranging from 0.85 (95% CI: 0.79-0.91) to 1.00 (95% CI: 1.00-1.00). For continuous and time variables there were detected high values of intraclass correlation coefficients (ICC) between 0.88 (95% CI: 0.83-0.91) and 1.00 (CI 95%: 1.00-1.00). While missing values in both the NTR and EPRs were in general negligeable, we found a substantial amount of missing registrations for a continuous "Base excess" in the NTR. For some of the time variables missing values both in the NTR and EPRs were high. CONCLUSION All tested variables in the Norwegian Trauma Registry displayed excellent agreement with the corresponding variables in electronic patient records. Variables in the registry that showed missing data need further examination.

Low interobserver and intraobserver reliability using the Matta radiographic system for intraoperative assessment of reduction following acetabular ORIF. Injury 2022; 53:2595-2599. [PMID: 35641334 DOI: 10.1016/j.injury.2022.05.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 02/26/2022] [Accepted: 05/08/2022] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The system described by Matta for rating acetabular fracture quality of reduction following ORIF has been used extensively throughout the literature. However, the reliability of this system remains to be validated. We sought to determine the interobserver and intraobserver reliability of this system when used by fellowship-trained pelvic and acetabular surgeons to evaluate intraoperative fluoroscopy. METHODS This is a retrospective evaluation of a prospectively collected acetabular fracture database at an academic level I trauma center. The quality of reduction of all acetabular fractures treated with open reduction internal fixation (ORIF) between May 2013 and December 2015 was assessed using three standard intraoperative fluoroscopic views (anteroposterior and two 45˚ oblique Judets). Displacement of ≤1 mm was considered to be an anatomic reduction, 2-3 mm imperfect, and >3 mm poor according to the system described by Matta. A total of 107 acetabular fractures treated with ORIF with complete intraoperative fluoroscopic images during that time period were available for review. Acetabular fracture reductions were reviewed by the operative surgeon at the time of surgery and subsequently reviewed by two fellowship-trained pelvic and acetabular surgeons. All reduction assessments were performed in a blinded fashion. The primary outcome measure was interobserver reliability for assessing reduction quality. This was evaluated using a weighted kappa (κw) statistic between each evaluator and the operative surgeon and a generalized kappa (κg) for all 3 surgeons. After a 6-week "washout interval," the surgeons reviewed the images again and intraobserver agreement was calculated using a weighted kappa statistic. RESULTS Interobserver reliability based on the initial assessment was low (κg = 0.09); however, did slightly improve with the second assessment to fair (κg = 0.24). Intraobserver reliability ranged from slight (κw = 0.20) to moderate (κw = 0.53) among the surgeons. DISCUSSION Low interobserver and intraobserver reliability was found when quality of reduction was assessed with intraoperative fluoroscopic images by the operative and two other pelvic and acetabular surgeons using the Matta system. Given the importance of an anatomic reduction on functional and radiographic outcomes, an accurate and reliable system for assessing intraoperative quality of reduction is essential.

Abstract
OBJECTIVES We aimed at identifying and analyzing the accuracy of YouTube videos on colostomy and ileostomy. METHODS YouTube website was searched independently by researchers for videos on colostomy and ileostomy posted before the 18th of May, 2019. Based on predetermined inclusion and exclusion criteria, the videos matching the research objective were identified. Data related to each video were collected, and the videos were categorized using standardized criteria. RESULTS A total of 357 videos were identified. Finally, 149 videos were included in the study. Of these, 52 (35%) were educationally useful, and 97 (65%) were not useful. None of the video parameters, including the number of viewers, duration, number of likes or dislikes, days on YouTube or number of comments, was able to differentiate between useful or not useful videos. The score of videos was 14.7 ± 0.6 for valuable videos and 11.0 ± 2.0 for not useful videos (p < 0.001). CONCLUSIONS While there were a reasonably number of colostomy and ileostomy videos, there was a smaller number on the surgical procedure. Most non-educational videos were not consistent with clinical guidelines. PRACTICAL IMPLICATIONS YouTube videos on colostomy/ileostomy care can be an important educational resource to patients. However, a collaboration between patients, nurse educators and universities/hospitals is needed to produce high-quality videos.

Abstract
BACKGROUND Diabetes is associated with increased hospital complications and mortality following trauma. However, there is limited research on the longer-term recovery of trauma patients with diabetes. The aim of this study was to explore the association between type 2 diabetes (T2D) and in-hospital and 24-month outcomes in major trauma patients. METHODS In this cohort study using the Victorian State Trauma Registry, middle-aged and older adults (≥45 years) with major trauma were followed up at 24 months postinjury. Logistic regression (univariable and multivariable) analyses were used to determine the association between diabetes status and 24-month patient-reported outcomes. In-hospital outcomes were compared between groups using χ2 tests. RESULTS Of the 11,490 participants who survived to hospital discharge, 8,493 survived to 24 months postinjury and were followed up at that time point: 953 people (11%) with and 7540 (89%) without T2D. People with T2D had a higher in-hospital death rate (19%) compared with people without T2D (16%; p < 0.001). After adjusting for confounders, people with T2D had poorer outcomes 24 months postinjury than people without T2D, with respect to functional recovery (Glasgow Outcome Scale Extended) (adjusted odds ratio [AOR], 0.58; 95% confidence interval [CI], 0.48-0.69) and return to work/study (AOR, 0.51; 95% CI, 0.37-0.71]). People with T2D experienced higher odds of problems with mobility (AOR, 1.92; 95% CI, 1.60-2.30), self-care (AOR, 1.94; 95% CI, 1.64, 2.29), usual activities (AOR, 1.50; 95% CI, 1.26-1.79), pain and discomfort (AOR, 1.75; 95% CI, 1.49-2.07), anxiety and depression (AOR, 1.45; 95% CI, 1.24, 1.70), and self-reported disability (AOR, 1.51; 95% CI, 1.28-1.79) than people without T2D. CONCLUSION Major trauma patients with T2D have a poorer prognosis than patients without T2D, both during their hospital admission and 24 months postinjury. Patients with T2D may need additional health care and support following trauma to reach their recovery potential. LEVEL OF EVIDENCE Prognostic, level III.

Abstract
IMPORTANCE An interview is considered the gold standard method of assessing global functional outcomes in clinical trials among patients with acute traumatic brain injury (TBI). However, several multicenter clinical trials have used questionnaires completed by a patient or caregiver to assess the primary end point. OBJECTIVE To examine agreement between interview and questionnaire formats for assessing TBI outcomes and to consider whether an interview has advantages. DESIGN, SETTING, AND PARTICIPANTS This cohort study used data from patients enrolled in the Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) project from December 2014 to December 2017. Data were analyzed from December 2020 to April 2021. Included patients were aged 16 years or older with TBI and a clinical indication for computed tomography imaging. Outcome assessments were completed using both an interview and a questionnaire at follow-up 3 and 6 months after injury. EXPOSURES Traumatic brain injury of all severities. MAIN OUTCOMES AND MEASURES Ratings on the Glasgow Outcome Scale-Extended (GOSE) administered as a structured interview rated by an investigator and as a questionnaire completed by patients or caregivers and scored centrally were compared, and the strength of agreement was evaluated using weighted κ statistics. Secondary outcomes included comparison of different sections of the GOSE assessments and the association of GOSE ratings with baseline factors and patient-reported mental health, health-related quality of life, and TBI symptoms. RESULTS Among the 3691 eligible individuals in the CENTER-TBI study, both GOSE assessment formats (interview and questionnaire) were completed by 994 individuals (26.9%) at 3 months after TBI (654 [65.8%] male; median age, 53 years [IQR, 33-66 years]) and 628 (17.0%) at 6 months (409 [65.1%] male; median age, 51 years [IQR, 31-64 years]). Outcomes of the 2 assessment methods agreed well at both 3 months (weighted κ, 0.77; 95% CI, 0.73-0.80) and 6 months (weighted κ, 0.82; 95% CI, 0.78-0.86). Furthermore, item-level agreement between the 2 methods was good for sections regarding independence in everyday activities (κ, 0.70-0.79 across both time points) and moderate for sections regarding subjective aspects of functioning such as relationships and symptoms (κ, 0.41-0.51 across both time points). Compared with questionnaires, interviews recorded more problems with work (294 [30.5%] vs 233 [24.2%] at 3 months and 161 [26.8%] vs 136 [22.7%] at 6 months), fewer limitations in social and leisure activities (330 [33.8%] vs 431 [44.1%] at 3 months and 179 [29.7%] vs 219 [36.4%] at 6 months), and more symptoms (524 [53.6%] vs 324 [33.1%] at 3 months and 291 [48.4%] vs 179 [29.8%] at 6 months). Interviewers sometimes assigned an overall rating based on judgment rather than interview scoring rules, particularly for patients with potentially unfavorable TBI outcomes. However, for both formats, correlations with baseline factors (ρ, -0.13 to 0.42) and patient-reported outcomes (ρ, 0.29 to 0.65) were similar in strength. CONCLUSIONS AND RELEVANCE In this cohort study, GOSE ratings obtained by questionnaire and interview methods were in good agreement. The similarity of associations of the ratings obtained by both GOSE methods with baseline factors and other TBI outcome measures suggests that despite some apparent differences, the core information collected by both interviews and questionnaires was similar. The findings support the use of questionnaires in studies in which this form of contact may offer substantial practical advantages compared with interviews.

Abstract
Background Supplemental oxygen administration to critically ill patients is ubiquitous in the intensive care unit (ICU). Uncertainty persists as to whether hyperoxia is benign in patients with traumatic brain injury (TBI), particularly in regard to their long-term functional neurological outcomes. Methods We conducted a retrospective multicenter cohort study of invasively ventilated patients with TBI admitted to the ICU. A database linkage between the Australian and New Zealand Intensive Care Society Adult Patient Database (ANZICS-APD) and the Victorian State Trauma Registry (VSTR) was utilized. The primary exposure variable was minimum acute physiology and chronic health evaluation (APACHE) III PaO2 in the first 24 h of ICU. We defined hypoxia as PaO2 < 60 mmHg, normoxia as 60–299 mmHg, and hyperoxia as ≥ 300 mmHg. The primary outcome was a Glasgow Outcome Scale-Extended (GOSE) < 5 at 6 months while secondary outcomes included 12 and 24 months GOSE and mortality at each of these timepoints. Additional sensitivity analyses were undertaken in the following subgroups: isolated head injury, patients with operative intervention, head injury severity, and PaO2 either subcategorized by increments of 60 mmHg or treated as a continuous variable. Results A total of 3699 patients met the inclusion criteria. The mean age was 42.8 years, 77.7% were male and the mean acute physiology and chronic health evaluation (APACHE) III score was 60.1 (26.3). 2842 patients experienced normoxia, and 783 hyperoxia. The primary outcome occurred in 1470 (47.1%) of patients overall with 1123 (47.1%) from the normoxia group and 312 (45.9%) from the hyperoxia group—odds ratio 0.99 (0.78–1.25). No significant differences in outcomes between groups at 6, 12, and 24 months were observed. Sensitivity analyses did not identify subgroups that were adversely affected by exposure to hyperoxia. Conclusions No associations were observed between hyperoxia in ICU during the first 24 h and adverse neurological outcome at 6 months in ventilated TBI patients.

Abstract
INTRODUCTION This study investigated which patient and injury characteristics are associated with 12-month mortality rates and living independently after isolated hip fracture. METHODS Older adults aged ≥65 years were included if they had an isolated hip fracture, were admitted to hospital between July 2009 and June 2016, inclusive, and were registered to the Victorian Orthopaedic Trauma Outcomes Registry. Mortality up to 12 months (365 days) post-injury, and functional outcomes (Glasgow Outcome Scale-Extended; GOS-E) at 12 months post-injury were examined. Multivariable Cox proportional hazards regression was used to estimate adjusted hazard ratios (aHRs), and multivariable logistic regression was used to identify predictors of living independently compared with severe disability or death on the GOS-E. RESULTS 4,912 patients were included, of whom 28% died, 46% had moderate-severe disability, and 26% were living independently 12 months post-injury. Mortality rates were lower in women (aHR=0.56, 95%CI: 0.50, 0.63), and in people injured in a high fall vs low fall (aHR=0.47, 95%CI: 0.31, 0.72). Mortality rates were higher in people in the older age groups (75-84 years: aHR=1.53, 95%CI: 1.21, 1.93; 95+ years: aHR=3.58, 95%CI: 2.68, 4.77), living in areas with the highest level of socioeconomic disadvantage (aHR=1.25, 95%CI: 1.01, 1.55), with a Charlson Comorbidity Index weighting of one (aHR=1.60, 95%CI: 1.36, 1.88) or more than one (aHR=2.21, 95%CI: 1.94, 2.53), whose injury occurred in a residential institution versus at home (aHR=2.63, 95%CI: 1.97, 3.52), that resulted in intensive care unit admission (aHR=1.68, 95%CI: 1.21, 2.32), and in people who did not have surgery versus people who had internal fixation (aHR=1.65, 95%CI: 1.33, 2.04). Independent living was inversely associated with most of the same characteristics; however, people also had lower odds of living independently if they were from metropolitan residential areas versus rural areas (aOR=0.77, 95%CI: 0.62, 0.96), or had mild to moderate (aOR=0.33, 95%CI: 0.27, 0.39) or marked to severe (aOR=0.13, 95%CI: 0.09, 0.20) preinjury disability vs no preinjury disability. CONCLUSIONS Characteristics that are associated with social disadvantage, frailty, poor health and reduced independence before injury were associated with increased rates of death and reduced odds of living independently 12 months after isolated hip fracture.

The road to recovery for vulnerable road users hospitalised for orthopaedic injury following an on-road crash. ACCIDENT; ANALYSIS AND PREVENTION 2019; 132:105279. [PMID: 31491683 DOI: 10.1016/j.aap.2019.105279] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Revised: 07/01/2019] [Accepted: 08/21/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Pedestrians, cyclists and motorcyclists are vulnerable to serious injury due to limited external protective devices. Understanding the level of recovery, and differences between these road user groups, is an important step towards improved understanding of the burden of road trauma, and prioritisation of prevention efforts. This study aimed to characterise and describe patient-reported outcomes of vulnerable road users at 6 and 12 months following orthopaedic trauma. METHODS A registry-based cohort study was conducted using data from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and included pedestrians, cyclists and motorcyclists who were hospitalised for an orthopaedic injury following an on-road collision that occurred between January 2009 and December 2016. Outcomes were measured using the 3-level EuroQol 5 dimensions questionnaire (EQ-5D-3 L), Glasgow Outcome Scale - Extended (GOS-E) and return to work questions. Outcomes were collected at 6 and 12 months post-injury. Multivariable generalized estimating equations (GEE), adjusted for confounders, were used to compare outcomes between the road user groups over time. RESULTS 6186 orthopaedic trauma patients met the inclusion criteria during the 8-year period. Most patients were motorcyclists (42.8%) followed by cyclists (32.6%) and pedestrians (24.6%). Problems were most prevalent on the usual activities item of the EQ-5D-3 L at 6-months post-injury, and the pain/discomfort item of the EQ-5D-3 L at 12 months. The adjusted odds of reporting problems on all EQ-5D-3 L items were lower for cyclists when compared to pedestrians. Moreover, an average cyclist had a greater odds of a good recovery on the GOS-E, (AOR 2.75, 95% CI 2.33, 3.25) and a greater odds of returning to work (AOR = 3.13, 95% CI 2.46, 3.99) compared to an average pedestrian. CONCLUSION Pedestrians and motorcyclists involved in on-road collisions experienced poorer patient-reported outcomes at 6 and 12 months post-injury when compared to cyclists. A focus on both primary injury prevention strategies, and investment in ongoing support and treatment to maximise recovery, is necessary to reduce the burden of road trauma for vulnerable road users.

Abstract
BACKGROUND Registries are becoming increasingly more important in clinical research. The TraumaRegister DGU® of the German Society for Trauma Surgery plays an excellent role with respect to the care of severely injured patients. AIM Within the framework of this investigation the quality of data provided by this registry was to be verified. MATERIAL AND METHODS Certified hospitals participating in the TraumaNetzwerk DGU® of the German Society for Trauma Surgery are obliged to submit data of treated severely injured patients to the TraumaRegister DGU®. Participating hospitals have to undergo a re-certification process every 3 years. Within the framework of this re-audit, data from 5 out of 8 randomly chosen patient cases included in the registry are controlled and compared to the patient files of the certified hospital. In the present investigation discrepancies concerning data provided were documented and the pattern of deviation was analyzed. RESULTS The results of 1075 re-certification processes carried out in 631 hospitals including the documentation of 5409 checked patient cases from 2012-2017 were analyzed. The highest number of discrepancies detected concerned the documented time until initial CT (15.8%) and the lowest concerned the discharge site (3.2%). The majority of data sheets with discrepancies showed deviations in only one out of seven checked parameters. Interestingly, large trauma centers with a high throughput of severely injured patients showed the most deviations. CONCLUSION The present investigation underlines the importance of standardized checks concerning data provided for registries in order to be able to guarantee an improvement in entering data.

Abstract
BACKGROUND Newspapers are considered one of the most viewed and influential media sources in both the United Kingdom and United States. However, information about how newspapers portray health care apps to the readers has been lacking. OBJECTIVE This study investigated the reporting on health care apps in newspapers published in the United Kingdom and United States. METHODS The Nexis UK database was used to identify and select relevant articles. Systematic content analysis of the articles that met the inclusion criteria (articles of any format that contained reference to health care apps or medical apps) within the highest circulated newspapers in the United Kingdom and United States over a period of 10 years (2006-2015) was conducted. Interrater reliability of coding was established using a 10% sample of the chosen articles. RESULTS A total of 220 (151 UK and 69 US) relevant newspaper articles were retrieved. Health care apps were most frequently reported on in the Daily Mail and The Guardian (UK newspapers) and in the New York Times and the Washington Post (US newspapers). An exponential rise in published scientific articles (PubMed) on health care-related apps was noted during the study period. A total of 26.4% (58/220) and 19.1% (42/220) of the retrieved newspaper articles appeared in the features and main news sections, respectively. General information about health care apps was the main theme coved by the newspapers (45.9%, 101/220). Most of the articles represented a societal point of view (72.3%, 159/220). The main focus of the articles was on general health matters (48.2%, 106/220) and specific disease matters (36.8%, 81/220). Diabetes was the most frequently mentioned disease in the articles. A high proportion (91.4%, 201/220) of the articles mentioned benefits of using health care apps mainly for personalized care, whereas 24.1% (53/220) of the articles commented on related risks such as anxiety and confidentiality issues. Almost half (45.9%, 101/220) of the articles mentioned potential facilitators to the use of apps; less than 10% (16/220) discussed barriers. Most of the articles (83.6%, 184/220) were judged as having balanced judgment on the present topic and more than half (60.0%, 132/220) of the articles were judged to be of generally low quality. CONCLUSIONS Health care apps were not widely reported in newspaper articles in the United Kingdom and United States over the study period; however, there appeared to be much more recent interest. Characteristically, the articles focused more frequently on societal impact and on general health rather than on disease-specific apps.

Abstract
OBJECTIVES Compensable injury increases the likelihood of having persistent pain after injury. Three-quarters of patients report chronic pain after traumatic injury, which is disabling for about one-third of patients. It is important to understand why these patients report disabling pain, in order to develop targeted preventative interventions. This study examined the experience of pain and disability, and investigated their sequential interrelationships with, catastrophising, kinesiophobia and self-efficacy 1 year after compensable and non-compensable injury. DESIGN Observational registry-based cohort study. SETTING Metropolitan Trauma Service in Melbourne, Victoria, Australia. PARTICIPANTS Participants were recruited from the Victorian State Trauma Registry and Victorian Orthopaedic Trauma Outcomes Registry. 732 patients were referred to the study, 82 could not be contacted or were ineligible, 217 declined and 433 participated (66.6% response rate). OUTCOME MEASURES The Brief Pain Inventory, Glasgow Outcome Scale, EuroQol Five Dimensions questionnaire, Pain Catastrophising Scale, Pain Self-Efficacy Questionnaire, Injustice Experience Questionnaire and the Tampa Scale of Kinesiophobia. METHODS Direct and indirect relationships (via psychological appraisals of pain/injury) between baseline characteristics (compensation, fault and injury characteristics) and pain severity, pain interference, health status and disability were examined with ordinal, linear and logistic regression, and mediation analyses. RESULTS Injury severity, compensable injury and external fault attribution were consistently associated with moderate-to-severe pain, higher pain interference, poorer health status and moderate-to-severe disability. The association between compensable injury, or external fault attribution, and disability and health outcomes was mediated via pain self-efficacy and perceived injustice. CONCLUSIONS Given that the associations between compensable injury, pain and disability was attributable to lower self-efficacy and higher perceptions of injustice, interventions targeting the psychological impacts of pain and injury may be especially necessary to improve long-term injury outcomes.

Abstract
OBJECTIVE To pilot a method for routine outcome data collection one year after admission to a major trauma centre, to determine current outcomes, and to identify possible methodological improvements. DESIGN A postal questionnaire audit. SETTING A major trauma centre in the United Kingdom. SUBJECTS In total, 355 patients known to be alive 12 months after admission with major trauma (Injury Severity Score (ISS) of 9 or more). INTERVENTIONS All patients received standard trauma and rehabilitation services available to them. MAIN MEASURES The main measures used are as follows: ISS; EuroQol, five dimensions five levels (EQ-5D-5L); single questions about accommodation, mobility, and self-care; demographic and injury data collected from hospital records; and outcome data by postal questionnaire. RESULTS In total, 429 patients were registered over six months: at one year, 64 had died and 10 had no UK address. In total, 355 questionnaires were sent out: 179 (50%) were never returned, 154 (43%) were returned with complete data, 11 forms were incomplete, 7 patients were dead, and 4 were not at the address contacted. Of the 154 with complete data, 91 had new mobility problems and 54 had new problems with personal activities. Of the 68 previously employed, 19 were unemployed, 38 were fully employed in the same job, and 13 had altered jobs. There was no association between Injury Severity Score and any of the outcome scores. CONCLUSION A short simple questionnaire sent only once achieved a complete data set response rate of 43%. The outcome data are consistent with experience in other studies. Collection of data on specific functional outcomes might be most sensitive.

Abstract
BACKGROUND/PURPOSE It has been suggested that hospital admission during weekends poses a risk for adverse outcomes and increased patient mortality, the so-called 'weekend effect'. We undertook an evaluation of the impact of weekend admissions to the management of polytraumatised patients, in a Level I Major Trauma Centre (MTC) in the UK. MATERIALS AND METHODS A retrospective review of prospectively documented data of polytrauma patients (injury severity score (ISS)>15), admitted between April 2013 and August 2015 was performed. Exclusion criteria included patients initially assessed in other institutions. All patients were initially managed at the emergency department (ED) according to ATLS® principles and underwent a trauma computed tomography (CT) scan, unless requiring immediate surgical intervention. RESULTS During the study period 1735 patients (pts) were admitted under the care of the MTC. Four hundred and five pts were excluded as they were transferred from other institutions and 300 pts were excluded as their ISS was less than 16. Overall 1030 patients met the inclusion criteria, out of which 731 were males. Comparing the two groups (Group A: weekday admissions (670), Group B: weekend admissions (360)), there was no difference in pts gender, mechanism of injury, GCS at presentation, need for intubation and time to CT. Patients admitted over the weekend were younger (p<0.01) and presented with haemodynamic instability more frequently (p=0.02). Time to operating room was also lower during the weekend, but this did not reach statistical significance (p=0.08). Mortality was lower in Group B: 39/360 pts (10.8%) compared to Group A: 100/670 pts (14.9%) (p=0.07). The relative risk (RR) of weekend mortality was calculated as 0.726 (95% CI: 0.513-1.027). DISCUSSION/CONCLUSION Weekend polytrauma patients appear to be younger, more severely injured and present with a higher incidence of haemodynamic instability (shock). Overall, we failed to identify a "weekend effect" in relation to mortality, time to CT and time to operating room. On the contrary, a lower risk of mortality was noted for patents admitted during the weekend.

Twelve-month mortality and functional outcomes in hip fracture patients under 65 years of age. Injury 2016; 47:2182-2188. [PMID: 27527378 DOI: 10.1016/j.injury.2016.05.033] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2016] [Accepted: 05/24/2016] [Indexed: 02/02/2023]
Abstract
INTRODUCTION There has been a recent call for improved functional outcome reporting in younger hip fracture patients. Younger hip fracture patients represent a different population with different functional goals to their older counterparts. Therefore, previous research on mortality and functional outcomes in hip fracture patients may not be generalisable to the younger population. The aims of this study were to report 12-month survival and functional outcomes in hip fracture patients aged <65 years and predictors of functional outcome. METHODS Hip fracture patients aged <65years (range 17-64) registered by the Victorian Orthopaedic Trauma Outcomes Registry over four years were included and their 12-month survival and functional outcomes (Extended Glasgow Outcome Scale) reported. Ordered multivariable logistic regression was used to identify predictors of higher function. RESULTS There were 507 patients enrolled in the study and of the 447 patients (88%) with 12-month outcomes, 24 (5%) had died. The majority of patients had no comorbidities or pre-injury disability and were injured via road trauma or low falls. 40% of patients sustained additional injuries to their hip fracture. 23% of patients had fully recovered at 12 months and 39% reported ongoing moderate disability. After adjusting for all key variables, odds of better function 12-months post-fracture were reduced for patients with co-morbidities, previous disability or additional injuries, those receiving compensation or injured via low falls. CONCLUSIONS While 12-month survival rates were satisfactory in hip fracture patients aged under 65 years, their functional outcomes were poor, with less than one quarter having fully recovered 12 months following injury. This study provides new information about which patients may have difficulty returning to their pre-injury level of function. These patients may require additional or more intensive post-discharge care in order to fulfil their functional goals and continue to contribute productively to society.

Abstract
BACKGROUND The impact of conventional laboratory data to identify polytrauma patients at risk of complications is established. However, it has not been assessed in terms of prognostic accuracy for systemic complications (ARDS, organ failure). We therefore assessed the most predictive parameters for systemic complications and developed a scoring system for early grading of polytrauma patients. METHODS A population based trauma registry was used. INCLUSION CRITERIA age >16 years, Abbreviated Injury Score (AIS) of the abdomen or chest ≥ 3 points and treatment in an intensive care unit, or Injury Severity Score (ISS) ≥ 16 points. The primary endpoint was hospital mortality. Patients were graded according their risk of death: low risk of death (5-14% mortality), intermediate risk patients (15-39% mortality) and high risk (>40%). Routine clinical and laboratory parameters on admission were assessed to determine their specific relevance to describe the risk profile of the patient. Based on these data, a scoring system for the description of the clinical status was developed. Statistical analysis included uniand multivariate analysis. RESULTS 11.436 patients were included, the mean ISS was 22.7 ± 11.2 points, 73% were male, and 95.6% had blunt injuries. The most sensitive parameters were found to be the following ones: systolic blood pressure, INR, thrombocytes, base deficit, NISS, packed red blood cells administered. The multivariate analysis revealed the following threshold levels: BP 76-90 mmHg: r = 0.249, OR 1.283: Base deficit 8-10 r = 0.474, OR 1.606; INR 1.4-2 r = 0.160, OR 1.174; NISS 35-39 r = 0.9, OR 2.46; pBRC 3-14: r = 0.671, OR 1.957. The following ranges of score values were found to be associated with different patient status: <6 points: stable patients; 6-11 points: borderline condition; >11 points: unstable patients. When using this score, 80.6% were stable, 14.6% in a borderline condition and 4.8% unstable. CONCLUSION We developed a scoring system to discriminate polytrauma patients on admission that are at risk of systemic complications. Systolic blood pressure, INR, thrombocytes, base deficit, NISS, packed red blood cells administered are able to provide a prognosis of patients at risk of posttraumatic complications. Further prospective studies should be performed to verify this new scoring system.
