Opening the black box of registration practice for self-harm and suicide attempts in emergency departments: a qualitative study.

BACKGROUND: The World Health Organization has called for improved surveillance of self-harm and suicide attempts worldwide to benefit suicide prevention programs. International comparisons of registrations are lacking, however, and there is a need for systematically collected, high-quality data across countries. The current study investigated healthcare professionals' perceptions of registration practices and their suggestions for ensuring high-quality registration of self-harm and suicide attempts. METHODS: Qualitative interviews (N = 20) were conducted among medical secretaries, medical doctors, nurses, and registration advisers from psychiatric and somatic emergency departments in all regions of Denmark between September 2022 and March 2023. Content analysis was performed using NVivo. RESULTS: Despite great efforts to standardize and assure the quality of registration in Denmark, almost all the healthcare professionals perceived registration practice as inconsistent and unreliable. Codes are often misclassified or unused due to insufficient time, non-standardized training, or insufficient information. The interview informants suggested that coding guidelines should be simplified and made more visible, alongside technical solutions in the electronic health record system. CONCLUSION: The study findings resulted in eight overall recommendations for clinical practice that aim at improving the registration of patients presenting with self-harm or suicide attempts. This would be expected to help improve surveillance and prevention programs.

Change in injury pattern with mandatory, referred access compared to open access in an emergency department.

INTRODUCTION: This retrospective cohort study aimed to examine whether implementing mandatory referral changed the composition of patients visiting the Accident and Emergency (A and E) Department in relation to severity, demographics and activity at injury. METHODS: Patients visiting the A and E Department at Odense University Hospital, Denmark, in 2008-2019, were divided into three time periods: before (four years before any changes in the operation of the A and E), transition period (the four years during which mandatory referral and the centralised emergency medical service were implemented) and after (the four years after these changes had been implemented). The incidence rate ratios and odds were calculated. RESULTS: The absolute number of severe injuries declined, but to a lesser extent than the number of minor injuries. The incidence rate ratios throughout all subcategories, including severity, fracture, sex, age and activity at injury, indicate a smaller risk of visiting the A and E Department in the after period than in the before period, with a total lower (0.82 times; 95% confidence interval: 0.82-0.83 times) risk of visiting the A and E Department in the after period than in the before period. CONCLUSIONS: Changing from open to referred access altered the composition of injuries for patients seen in the A and E Department, indicating a smaller risk of a visit with referred access than with open access. The odds of a visit being due to a major injury increased after implementing referred access, and the number of visits decreased. FUNDING: The Nordentoft Fund TRIAL REGISTRATION. Not relevant.

Age-related trends in unintentional injuries among children and adolescents in an urban Danish population 1980-2021. A cohort study of 292,737 children and adolescents.

OBJECTIVE: This study describes the age-related trends in unintentional injuries in children and adolescents in an urban population 1980-2021. A retrospective study of all children and adolescents aged 0-17 years treated for unintentional injuries at Odense University Hospital, Denmark 1980-2021. METHODS: Information about age, gender, place of injury, and diagnoses from the emergency department register. We estimated gender specific annual incidence rates (IRs) in different age groups (0-4, 5-9, 10-14, and 15-17 years) per 1000 population/years. The severity was classified by mild or severe injuries. RESULTS: Overall, 292,737 unintentionally injured children and adolescents were included. The median age was 10 years and 57.4 % were boys. The overall IR was 241 (CI: 240-242) for boys and 188 (CI: 187-188) for girls per 1000 population/years. In the study period, the overall incidence decreased by 44 % in boys and by 38 % in girls. The overall IR for severe injuries did not change in the study period, whereas the IR of mild injuries decreased significantly in all age groups in both gender. The upper limbs were the most frequently injured in all age groups for both gender, except for children aged 0-4 years, where lesions mostly occurred in the head or neck. In the youngest age groups 0-4 years and 5-9 years wounds were the most common type of lesion, while bruises were the most common type of lesion in the oldest age groups. Fractures accounted for 14.5 % of the lesions with the highest proportions in the 5-9 years and 10-14 years age group. CONCLUSION: The study provides information, which is useful when coordinating the resources at emergency departments and for planning preventive campaigns targeting different age groups.

The completeness of routine registration of the counterpart in deliberate interpersonal violence in an urban emergency department.

Most studies of violence from the health care system lack reliable information about the counterpart, which is important for distinguishing between different types of violence. Since 2014, the emergency department at Odense University Hospital in Denmark has routinely registered information about the counterpart. The purpose of this study was to evaluate the completeness of registering information about the counterpart during routine registration of victims of interpersonal violence in the emergency department. We included 11,200 victims treated at the emergency department 2014-2021. Using the patient registration data, we estimated the proportion of missing information on the counterpart, stratified by age group and gender of the victim as well as type of incident and severity of injury. Information about the counterpart was registered in 91.5 % of all cases. In 43.1 % (CI: 42.2-44.0) of the cases, the counterpart was unknown to the victim, in 24.3 % (CI: 23.5-25.1) the counterpart was an acquaintance, in 10.5 % (CI: 10.0-11.1) the counterpart was a partner, and in 4.2 % (CI: 3.8-4.5) the counterpart was another family member. The proportion of cases with no information about the counterpart varied with gender, age group, time of violence, place of violence, weapon use, and severity of injury. Half of the victims injured with firearms (46.2 %, CI: 30.1-62.8) and one-fourth of the victims injured with knives (25.9 %, CI: 21.9-30.2) did not reveal information about the counterpart. The majority of the victims revealed information about the counterpart, making it possible to analyse different types of violence separately.

Long-term stroke risk in Moyamoya disease.

BACKGROUND: Moyamoya disease (MMD) is considered a progressive disease with an ongoing risk of recurrent stroke. However, there is a lack of long-term observational data to quantify the extent of the stroke risk. METHODS: This study aimed to provide insight into the long-term stroke risk in MMD and explore possible risk factors for stroke. Records from all patients diagnosed with MMD in 13 clinical departments from 6 different Danish hospitals between 1994 and 2017 were retrospectively reviewed until 2021. RESULTS: The cohort comprised 50 patients (33 females and 17 males). Patients were followed up for a median of 9.4 years, with more than 10 years of follow-up for 24 patients. Ten patients had 11 new stroke events-6 ischemic strokes and 5 brain hemorrhages. Events occurred at a median of 7 years and up to 25 years after diagnosis. The overall Kaplan-Meier 5-year stroke risk was 10%. Patients with bypass performed had significantly fewer events than conservatively treated patients (HR 0.25, 95% confidence interval (CI) 0.07-0.91, p < 0.05). All but one event occurred in females, a difference that reached statistical significance. CONCLUSIONS: The study provides data on the extent of the risk of recurrent stroke in MMD. Bypass surgery patients had fewer stroke events than those treated conservatively. There was a trend toward a higher stroke risk in females. DATA ACCESS STATEMENT: The data supporting this study's findings are available from the corresponding author upon reasonable request.

Definitions and incidence rates of self-harm and suicide attempts in Europe: A scoping review.

INTRODUCTION: European countries use various terminologies for self-harm and attempted suicide, which are sometimes used interchangeably. This complicates cross-country comparisons of incidence rates. This scoping review aimed to examine the definitions used and the possibilities to identify and compare incidence rates of self-harm and attempted suicide in Europe. METHODS: A literature search was conducted in Embase, Medline and PsycINFO for studies published from 1990 to 2021, followed by grey literature searches. Data were collected for total populations originating from health care institutions or registries. Results were presented in tabular form supplemented by a qualitative summary by area. RESULTS: A total of 3160 articles were screened, resulting in 43 studies included from databases and further 29 studies from other sources. Most studies used the term 'suicide attempt' rather than 'self-harm' and reported person-based rates with annual incidence rates from age 15+. None of the rates were considered comparable due to different reporting traditions related to classification codes and statistical approaches. CONCLUSION: The present extensive literature on self-harm and attempted suicide cannot be used to compare findings between countries because of the high degree of heterogeneity among studies. International agreement on definitions and registration practices is needed to improve knowledge and understanding of suicidal behaviour.

The first COVID-19 lockdown's impact on hand injuries at a Danish accident and emergency department.

INTRODUCTION: During the lockdown of the COVID-19 pandemic in Denmark in March 2020, the trauma Accidents and Emergency (A and E) Department of Odense University Hospital, Denmark, experienced a marked decline in visits. We had the impression that the decline in visits for non-severe injuries was larger than that for severe injuries. METHODS: We analysed the incident rate ratio (IRR) between the first month of the lockdown with the IRR recorded in the month leading up to the lockdown. We then compared this IRR with the IRR for the equivalent periods of 2019. The outcomes were: diagnoses (or diagnosis groups), activity during injury (ADI), mechanisms of injury, age group and gender. Secondarily, certain specific diagnoses (or diagnosis groups) were analysed by ADI and mechanism of injury. RESULTS: We observed a significant reduction by 30.6% of all hand injuries in 2020. The non-severe injuries had a significant IRR reduction of 58.7% and the severe injuries a reduction of 15.3%, which was non-significant. The IRR in 2020 was significantly lower in 2020 for the age groups: 0-14, 15-17 and 25-49 years. The relative reduction in IRR was markedly larger for men (40.8%) than for women (22.3%), although this difference was not significant. CONCLUSION: We observed a greater reduction in non-severe injuries than in severe injuries compared with 2019. Further studies are needed to fully examine the cause of this phenomenon. The reduction may be caused, in part, by a more restrictive attitude towards seeking medical help at a trauma A and E during the first COVID-19 lockdown.

Risk of mortality and reoperation in hip fracture patients undergoing cemented versus uncemented hemiarthroplasty : a population-based study from Danish National Registries.

AIMS: The aim of this study was to assess the association of mortality and reoperation when comparing cemented and uncemented hemiarthroplasty (HA) in hip fracture patients aged over 65 years. METHODS: This was a population-based cohort study on hip fracture patients using prospectively gathered data from several national registries in Denmark from 2004 to 2015 with up to five years follow-up. The primary outcome was mortality and the secondary outcome was reoperation. Hazard ratios (HRs) for mortality and subdistributional hazard ratios (sHRs) for reoperations are shown with 95% confidence intervals (CIs). RESULTS: A total of 17,671 patients with primary HA were identified (9,484 uncemented and 8,187 cemented HAs). Compared to uncemented HA, surgery with cemented HA was associated with an absolute risk difference of 0.4% for mortality within the period zero to one day after surgery and an adjusted HR of 1.70 (95% CI 1.22 to 2.38). After seven days, there was no longer any association, with an adjusted HR of 1.07 (95% CI 0.90 to 1.28). This continued until five years after surgery with a HR of 1.01 (95% CI 0.96 to 1.06). There was a higher proportion of reoperations due to any reason after five years in the uncemented group with 10.2% compared to the cemented group with 6.1%. This yielded an adjusted sHR of 0.65 (95% CI 0.57 to 0.75) and difference continued up until five years after the surgery, demonstrating a sHR of 0.70 (95% CI 0.59 to 0.83). CONCLUSION: In a non-selected cohort of hip fracture patients, surgery with cemented HA was associated with a higher relative mortality during the first postoperative day compared to surgery with uncemented HA, but there was no difference after seven days up until five years after. In contrast, surgery with cemented HA was associated with lower risk of reoperation up to five years postoperatively compared with surgery with uncemented HA. There was a higher relative mortality on the first postoperative day for cemented HA versus uncemented HA. There was no difference in mortality after seven days up until five years after surgery. There were 6.1% reoperations for cemented HA compared to 10.2% for uncemented HA after five years. Cite this article: Bone Joint J 2022;104-B(1):127-133.

A population-based study of seasonal variation in children's fractures.

INTRODUCTION Few Scandinavian studies have studied seasonal variations in paediatric fractures, and the studies that have focused on individual fracture sites. Furthermore, their findings do not coincide as they have described peaks in different seasons. Therefore, we described seasonal variation in the incidence rate (IR) of all paediatric fractures in the 1996-2019 period within a Danish population. METHODS We extracted data from the existing emergency room register at Odense University Hospital and included all fractures sustained by children aged 0-14 years and living in Odense Municipality. Seasonal and monthly IR were calculated using population counts stratified by age, gender and fracture site. RESULTS We recorded a significant increase in IR in spring and summer, except for a drop in July. For boys, the IR ranged from 206 in December to 404 per 10,000 person-years in June. For girls, the incidence ranged from 156 in December to 317 in May. Fractures were more frequent in the upper extremities and were up to six-fold more frequent in the epiphysis and metaphysis than in the shafts. All fracture sites showed a peak in spring and summer, suggesting that all fracture sites are subject to seasonal variation, especially the ones near the epiphysis. CONCLUSIONS The fracture peak observed in spring and summer corresponds to an increase in physical activity. The low incidence registered in July corresponds to a low level of sport activities during the summer vacations and families going on vacation in the countryside or travelling abroad. This study gives useful information for coordinating the right resources at hospitals. FUNDING none TRIAL REGISTRATION not relevant.

Should Pertrochanteric and Subtrochanteric Fractures Be Treated with a Short or Long Intramedullary Nail?: A Multicenter Cohort Study.

BACKGROUND: The purpose of the present multicenter cohort study was to compare the rates of reoperation in elderly patients with pertrochanteric and subtrochanteric fractures that had been treated with a short or long intramedullary nail. METHODS: Eleven orthopaedic departments across Denmark delivered data that had been obtained from the Danish Multidisciplinary Hip Fracture Registry (DMHFR) and a review of health-care records. With use of surgical procedure codes for pertrochanteric and subtrochanteric fractures that had been treated with an intramedullary nail, the DMRHF was searched to identify patients who had been ≥65 years of age between 2008 and 2013. The health-care records for patients who had had major reoperations, defined as any reoperation with the exclusion of simple hardware removal, were retrieved from the DMHFR, were reviewed for the type of intramedullary nail and missed reoperations, including peri-implant fractures, within 2 years of follow-up. Crude logistic regression analysis with adjustment for age, sex, and comorbidity was performed, yielding odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: Of 2,245 pertrochanteric fractures, 1,867 were treated with a short intramedullary nail and 378 were treated with a long intramedullary nail. The rate of major reoperations was 4.0% in the short intramedullary nail group and 6.3% in the long intramedullary nail group. This yielded a crude OR of 1.61 (1.01 to 2.60) and an adjusted OR of 1.67 (1.04 to 2.70). Of 909 subtrochanteric fractures, 308 were treated with a short intramedullary nail and 601 were treated with a long intramedullary nail. The rate of major reoperations was 8.4% in the short intramedullary nail group and 4.0% in the long intramedullary nail group, yielding a crude OR of 0.45 (0.25 to 0.80) and an adjusted OR of 0.45 (0.25 to 0.81). CONCLUSIONS: This is the first study confirming the theory that, for subtrochanteric fractures, a long intramedullary nail has a lower rate of major reoperations compared with a short intramedullary nail. In contrast, a short intramedullary nail has a lower rate of major reoperations compared with a long intramedullary nail for pertrochanteric fractures but with a lower absolute risk reduction compared with the results for subtrochanteric intramedullary nailing. There is a need for validation of these results in other large studies, especially for pertrochanteric fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

Predictors of physical activity levels in children and adolescents with cerebral palsy: clinical cohort study protocol.

INTRODUCTION: Children and adolescents with cerebral palsy may be trapped in a vicious circle of low physical fitness, resulting in deconditioning that causes a further decrease in physical activity (PA), a lower quality of life and an increased risk of developing non-communicable diseases. Therefore, establishing a healthy and active lifestyle during childhood is even more important for individuals with a disability. However, the factors that influence habitual PA in children and adolescents with cerebral palsy remain unknown.The present protocol outlines a prospective cohort study with the aim of investigating potential predictors of habitual PA in children and adolescents with cerebral palsy in order to provide evidence for optimising PA levels and associated overall health. METHODS AND ANALYSIS: This prospective cohort study will enrol participants with cerebral palsy between the ages of 8 and 15 years at Gross Motor Function Classification System levels I-III. Using a modified version of the International Classification of Functioning, Disability and Health model as a conceptual analytical framework, the analysis will be divided into six components and will provide predictors for habitual PA measured by accelerometry. The potential predictive variables are registry data on physical function (Danish Cerebral Palsy Follow-Up Programme); validated proxy-reported questionnaires on quality of life (Paediatric Quality of Life Inventory), overall health, pain and participation in daily activities (Paediatric Outcomes Data Collection Instrument) and supplementary questions regarding sleep, screen time and socioeconomic status. ETHICS AND DISSEMINATION: The project is approved by the Danish Data Protection Agency (19/16396) and has been declared not notifiable by the Regional Committee on Health Research Ethics, cf. Committee Act Art. 14, paragraph 1 (S-20192000-23). The study results will be published in international peer-reviewed journals, presented at international conferences, and published in a PhD dissertation. TRIAL REGISTRATION NUMBER: NCT04614207.

European guidelines on radiographic image quality in chiropractic practice - proposal of a cross-sectional graded classification reporting principle.

BACKGROUND: The Commission of the European Communities (CEC) has published: European Guidelines on Quality Criteria for Diagnostic Radiographic Images. These guidelines are considered a gold standard, recommended for use in quality assurance protocols. The objectives of this study: 1) Propose a graded classification format for Danish chiropractic clinics according to the CEC-quality criteria for diagnostic radiographic images of the lumbar spine. 2) Propose a reporting principle for quality of radiographic images. 3) Document variation in radiation exposure among clinics. METHODS: This is a cross-sectional study of image quality based on random sampling from 148 chiropractic clinics. Clinics were included if using: 1) Digital radiography and 2) The chiropractic picture and archiving system (KirPACS) at the Nordic Institute of Chiropractic and Clinical Biomechanics (NIKKB) in Denmark. A sample of 296 lumbar spine series were randomly collected from KirPACS (January 2018). Two independent observers reviewed 50 lumbar spine series twice with a 4-week interval, testing intra- and inter-observer reproducibility. The same observers then reviewed the remaining 246 radiographic studies. All studies were evaluated using the CEC Quality Criteria. Patient radiation dose values were retrieved from KirPACS (First quarter of 2020). RESULTS: A reporting and classification principle of diagnostic image quality was used in 148 chiropractic clinics. Compliance with the 22 CEC Quality Criteria had proportions ranging from 0.72-0.96 for 18 criteria, while 4 criteria specifying detail and definition ranged between 0.20-0.66. The proposed rating system (A to E) revealed: 18 A clinics, 28 B clinics, 32 C clinics, 25 D clinics and 45 E clinics (A = highest quality; E = lowest quality). The patient radiation reference dose in Denmark is 7 mGy for the AP/PA lumbar spine. Very few clinics exceed the reference dose value, approximately 50% of clinics were below 5 mGy. CONCLUSION: A reporting principle is proposed for a graded classification format based on the CEC-quality criteria for diagnostic radiographic images of the lumbar spine. The Quality Criteria are for the most part met satisfactorily in 148 Danish chiropractic clinics, but important image details are compromised, in most cases, because of low patient radiation doses. The results of a patient radiation dose survey enabled documentation of variation in radiation exposure among chiropractic clinics.

Is tranexamic acid use in patients with a hip fracture safe?

AIMS: To assess the safety of tranexamic acid (TXA) in a large cohort of patients aged over 65 years who have sustained a hip fracture, with a focus on transfusion rates, mortality, and thromboembolic events. METHODS: This is a consecutive cohort study with prospectively collected registry data. Patients with a hip fracture in the Region of Southern Denmark were included over a two-year time period (2015 to 2017) with the first year constituting a control group. In the second year, perioperative TXA was introduced as an intervention. Outcome was transfusion frequency, 30-day and 90-day mortality, and thromboembolic events. The latter was defined as any diagnosis or death due to arterial or venous thrombosis. The results are presented as relative risk (RR) and hazard ratio (HR) with 95% confidence intervals (CIs). RESULTS: A total of 3,097 patients were included: 1,558 in the control group and 1,539 in the TXA group.31% (n = 477) of patients had transfusions in the control group compared to 27% (n = 405) in the TXA group yielding an adjusted RR of 0.83 (95% CI 0.75 to 0.91). TXA was not associated with increased 30-day mortality with an adjusted HR of 1.10 (95% CI 0.88 to 1.39) compared to the control group as well as no association with increased risk of 90-day mortality with a per protocol adjusted HR of 1.24 (95% CI 0.93 to 1.66). TXA was associated with a lower risk of thromboembolic events after 30 days (RR 0.63 (95% CI 0.42 to 0.93)) and 90 days (RR 0.72 (95% CI 0.52 to 0.99)). A subanalysis on haemoglobin demonstrated a median 17.7 g/L (interquartile range (IQR) 11.3 to 27.3) decrease in the control group compared to 17.7 g/L (IQR 9.7 to 25.8) in the per protocol TXA group (p = 0.060 on group level difference). CONCLUSION: TXA use in patients with a hip fracture, was not associated with an increased risk of mortality but was associated with lower transfusion rate and reduced thromboembolic events. Thus, we conclude that it is safe to use TXA in this patient group. Cite this article: Bone Joint J 2021;103-B(3):449-455.

Changes in the pattern of paediatric bicycle injuries in relation to helmet use 1980-2014.

INTRODUCTION: This study aimed to describe long-term changes in injury pattern in bicycle accidents among children in relation to the increasing use of bicycle helmets. METHODS: This was a descriptive register study of all children aged 6-14 years with injuries from bicycle accidents who were treated at a Danish university hospital in the 1980-2014 period. Diagnoses and helmet use were analysed and stratified by gender and age group. Diagnoses were grouped into head injuries, severe head injuries, facial injuries, bone fractures, spinal injuries and internal injuries. We defined severe head injuries as skull fractures and intracranial injuries including concussions, haemorrhages and lacerations. RESULTS: We included 13,294 children, 58.7% were boys. From 1980-1984 to 2010-2014, the use of helmets increased from 0% to 49.9% in boys and from 0% to 57.1% in girls. The proportion of boys and girls with head injuries decreased from 31.3% to 17.4% and from 29.6% to 10.1%, respectively. A similar reduction was found in the proportion of children with severe head injuries. In the study period, the proportion of children with facial injuries, fractures, spinal injuries and internal injuries in trunk remained unchanged. Eighteen children died from their injuries, none of whom wore a helmet. CONCLUSIONS: In the study period, the proportion of head and severe head injuries decreased by 50% along with an increase from 0% to 50% in helmet use. The proportion of facial injuries, spinal injuries, bone fractures and injuries to the internal organs remained unchanged. FUNDING: none. TRIAL REGISTRATION: not relevant.

Development of the annual incidence rate of fracture in children 1980-2018: a population-based study of 32,375 fractures.

Background and purpose - Pediatric fractures are a common cause of morbidity. So far, no larger Danish study has described the development in the incidence rates. Therefore, we describe the development in the incidence rates of pediatric fractures in the time period 1980-2018 and the frequency of the most common type of fractures.Patients and methods - This is a retrospective register study of all children aged 0-15 years with a fracture treated in the Emergency Department at Odense University Hospital, Denmark, between 1980 and 2018. For all cases, information on age, sex, date of treatment, diagnosis, and treatment was obtained from the patient registration system. Based on official public population counts we estimated age and sex-specific annual incidence rates.Results - 32,375 fractures were included. In the study period the incidence rate decreased by 12%. The incidence increased until the early 1990s. Thereafter incidence rates decreased until 2004-09, from then onward increasing towards the end of the study period. The highest age-specific incidence rate in boys of 522 per 10,000 person-years was at 13 years of age. In girls the age of the highest incidence rate decreased from 11 years in 1980 to 10 years in 2018. Fracture of the lower end of the forearm, the clavicle, and the lower end of the humerus had the highest single fracture incidence rates.Interpretation - The incidence rate of pediatric fractures decreased in the study period by 12%. The highest single fracture incidence rates were for fracture of the lower end of the forearm, the clavicle, and the lower end of the humerus. As the first longitudinal Danish study of pediatric fractures this study is a baseline for evaluating future interventions and future studies.

Objectively Measured Physical Activity and Its Association with Functional Independence, Quality of Life and In-Hospital Course of Recovery in Elderly Patients with Proximal Femur Fractures: A Prospective Cohort Study.

BACKGROUND: Physical activity in elderly patients is crucial for recovery from proximal femoral fractures. Considering the limited possibilities for objective measurement, we aimed to evaluate the use of an accelerometer in this population to determine activity's association with functional independence, quality of life, and course of recovery. METHODS: 52 patients undergoing operative treatment for proximal femur fractures (81.3 ± 7.5 years) were included in a prospective cohort study. 12 patients with fall but without fracture of the lower extremities (80.8 ± 9.5 years) served as control. An Axivity AX3 tracker continuously recorded signal vector magnitudes during the hospital stay. Additionally, 2 ± 1 and 8 ± 3 days (time point 1 and 2) after operation EuroQol-5D and Barthel-20 indices were evaluated. RESULTS: Physical activity increased in all patients with time. Multiple regression analyses revealed that a high Barthel-20 before fracture, a low age, a high body mass index, high albumin, and low C-reactive protein levels were independent predictors for high physical activity at time point 1 (p < 0.05). Physical activity correlated significantly with EuroQol-5D and Barthel-20 at time point 1 and 2 (p < 0.02). Furthermore, physical activity at time point 1 predicted EuroQol-5D, physical activity, and Barthel-20 at time point 2 (p < 0.01). A multiple regression demonstrated equal physical activity in patients with or without a hip fracture. CONCLUSIONS: Accelerometer signals correlate with postoperative physical activity, Barthel-20 and quality of life in elderly patients. Physical activity is thereby positively influenced by a high prefall functional independence and a good nutrition status. A timely and adequate operation provided, there is no difference between patients with or without a fracture. This trial is registered with DRKS 00011934 on 10th April 2017.

Social inequalities in unintentional childhood injury incidence suggest subgroup identification and differentiation in the municipal planning of preventive efforts.

Aims: This registry-based study examined differences according to socio-economic factors in the incidence of unintentional childhood injuries involving main injury types. Methods: All children aged 0-15 years living in the municipality of Odense were followed from January 1 2006 to December 31 2010 (n=176,585). Injury outcome (n=27,745) was defined as visits to the local emergency department. Cohort data were transferred to Statistics Denmark and linked with socio-economic registry data based on unique personal identification numbers. Results: Children aged 10-15 years were at the highest risk for any injury (incidence rate ratio (IRR)=1.14), traffic injury (IRR=5.89) and sports injury (IRR=49.58) compared to children aged 0-4 years. Girls were at lower risk for any injury (IRR=0.85) and higher risk for sports injury (IRR=1.11) and home injuries (IRR=1.12) compared to boys. Children of parents with the lowest household income were at the highest risk for any injury (IRR=1.19) and traffic injury (IRR=2.16) compared to children of parents with the highest group. Children of parents with primary education were at the highest risk of any injury (IRR=1.22) and the lowest risk of traffic injury (IRR=0.80) and sports injury (IRR=0.75) compared to children of parents with tertiary education. Immigrants and descendants were at lower risk for any injury (IRR=0.75 and 0.79, respectively) and sports injury (IRR=0.81 and 0.68, respectively) compared to Danish children. Conclusions: Injury risk varied with socio-economic factors in a Danish municipal setting. The effect varied between specific injury types. Social and ethnic background is important in establishing targeted preventive efforts, but some aspects of selection bias may occur.

European guidelines on quality criteria for diagnostic radiographic images of the lumbar spine - an intra- and inter-observer reproducibility study.

Background: The Commission of the European Communities has published guidelines to be used as a gold standard for quality assessment of diagnostic radiographic images. Image quality and radiation dose must be monitored and optimally balanced for diagnostic purposes on patients. The objective of the current study was to assess intra- and inter-observer reproducibility in less experienced observers using the proposed European Guidelines on Quality Criteria for Diagnostic Radiographic Images in a quality assessment of lumbar spine radiographs in primary chiropractic practice in Denmark. Methods: Two observers initially evaluated lumbar spine radiographs randomly selected from fifty chiropractic clinics, all connected to the national PACS server (KirPACS) in Denmark. All evaluations were performed twice by both observers using a four-week interval and for compliance with the European Quality Criteria for Diagnostic Radiographic Images. Inter- and intra-observer reproducibility was calculated using kappa statistics. In the interpretation of the kappa coefficient, the standards for strength of agreement reported by Landis and Koch were followed. Results: The strength of the inter-observer agreement of general image quality at baseline ranged from moderate agreement (k = 0.47) to substantial agreement (k = 0.68). After four weeks, the inter-observer agreement still ranged from moderate agreement (k = 0.59) to substantial agreement (k = 0.71), but with increased agreement for both kappa coefficients. In relation to intra-observer agreement of general image quality, the strength for observer A ranged from moderate (k = 0.58) to substantial (k = 0.72) and the strength for observer B overall was substantial (k = 0.63-0.75). Conclusion: The European Guidelines on Quality Criteria for Diagnostic Radiographic Images are considered a gold-standard and used in a method for quality assurance within the Danish chiropractic profession. The inter-rater and intra-rater agreements in this study, using the CEC-criteria, were found mostly acceptable. With appropriate attention to clear understanding of the individual criteria and sufficient training, this method is found to be reliable, even using less experienced observers, to carry out Diagnostic Radiographic Image Quality-assurance in primary care settings.

The effect of breed-specific dog legislation on hospital treated dog bites in Odense, Denmark-A time series intervention study.

As dog bite injuries are a considerable problem in modern society, in order to reduce such injuries, breed-specific legislation has been introduced in a number of countries. Whilst many studies have shown a lack of effect with such legislation, the commonly used methodology is known to be flawed. Therefore, the aim of this study is to investigate the effect of the Danish breed-specific legislation on the number of dog bite injuries using more credible methods. A time series intervention method was used on a detailed dataset from Odense University Hospital, Denmark, regarding dog bite injuries presented to the emergency department. The results indicate that banning certain breeds has a highly limited effect on the overall levels of dog bite injuries, and that an enforcement of the usage of muzzle and leash in public places for these breeds also has a limited effect. Despite using more credible and sound methods, this study supports previous studies showing that breed-specific legislation seems to have no effect on dog bite injuries. In order to minimise dog bite injuries in the future, it would seem that other interventions or non-breed-specific legislation should be considered as the primary option.
