Measuring the population burden of injuries--implications for global and national estimates: a multi-centre prospective UK longitudinal study

The influence of socioeconomic status on management and outcomes in major trauma: A systematic review and meta-analysis

BACKGROUND

Major trauma is a leading cause of death and disability in younger individuals and poses a significant public health concern. There is a growing interest in understanding the complex relationships between socioeconomic deprivation and major trauma. Anecdotal evidence suggests that deprivation is associated with more violent and debilitating injuries. There remains a paucity in literature evaluating major trauma outcomes in relation to socioeconomic deprivation.

METHODS

A comprehensive search of MEDLINE, Embase, and CENTRAL databases was performed to identify studies from 1947 to March 2024. The primary outcome was to establish the distribution of injuries based on deprivation, with secondary outcomes evaluating surgical intervention rates, length of stay, and mortality. Quantitative pooling of data was based on the random-effects model.

RESULTS

Fourteen studies and 878,872 trauma patients were included. A substantial proportion (28%) of trauma incidents occurred in the most deprived group. Patients from the lowest socioeconomic group were considerably younger (weighted mean difference [WMD] -9.85 years and 95% confidence intervals [CI] -9.99 to -9.70) and more likely to be male (odds ratio [OR] 1.36 and 95% CI 1.14-1.63). There were no differences in surgical intervention (OR 1.74 and 95% CI 0.97-3.13), length of stay (WMD 1.15 days and 95% CI -0.32-2.62), and mortality (OR 1.04 and 95% CI 0.95-1.14) regardless of background.

CONCLUSION

Major trauma is prevalent in deprived areas and in younger individuals, with an increasing trend of deprivation in male patients. Although the rates of surgery, length of stay, and mortality did not differ between groups, planning of public health interventions should target areas of higher deprivation.

Understanding patients' perspectives of clinical communication within a Major Trauma Centre

Clinical communication between major trauma patients (MTP) and healthcare professionals is extremely complex. Multiple demands are placed on specialist multi-disciplinary teams (MDT) and patients in all stages of treatment. Patient-staff clinical communication has an integral role in MTP healthcare experiences, supporting them with a range of physical and psychological difficulties post-injury. This study aimed to understand MTP perspectives of clinical communication within a MTC through qualitative semi-structured interviews. Twenty participants were purposively sampled from an outpatient follow-up clinic and interviews were analysed using a pluralistic qualitative approach. Three themes were conceptualised from the data; "Challenges to speaking up" "Conversations left me feeling" and "Strategies need to be clinical but tailored". Patients often found it challenging to speak up due to feelings of vulnerability, confusion, and challenges navigating medical terminology. Patients spoke of not wanting to burden staff and family members playing a role in patient-staff communication, but these challenges require further exploration. Patients highlighted the positive (feel reassured, cared for, and human again) and negative (feeling like an object, angry, confused, and dependent) emotional impact of staff communication. Patients also described the benefits of being provided with written information, clear explanations of injuries and person-centred communication. MTP require multiple options to communicate and address psychological difficulties. Greater training on the emotional impact of conversations, skills to respond to psychological distress and communication guidance for staff, is needed to improve clinical communication with MTP.

What affects implementation of the UK major trauma rehabilitation prescription? A survey informed by the behaviour change wheel

OBJECTIVE

Major trauma 'Rehabilitation Prescriptions' aim to facilitate continuity of care and describe patient needs following discharge from UK Major Trauma Centre (MTCs), however research suggests rehabilitation prescriptions are not being implemented as intended. We aimed to identify factors influencing completion and use of rehabilitation prescriptions using the Behaviour Change Wheel (BCW) and Theoretical Domains Framework (TDF).

DESIGN

Online survey informed by the TDF and BCW.

SETTING

UK trauma rehabilitation pathway.

POPULATION

Rehabilitation and trauma service providers involved in completing and/or using rehabilitation prescriptions (n = 78).

ANALYSIS

Mean scores were calculated for TDF behavioural domains, identifying facilitators (score ≥5) and barriers (≤3.5) to rehabilitation prescription implementation. Thematic analysis of free text data informed by the BCW/TDF identified further facilitators and barriers, plus potential behaviour change strategies.

RESULTS

Most respondents worked in UK MTCs (n = 63) and were physiotherapists (n = 34), trauma rehabilitation coordinators (n = 16) or occupational therapists (n = 15). 'Social/professional role and identity', 'knowledge' and 'emotion' (the highest-scoring TDF domains) were facilitators to implementing rehabilitation prescriptions. Qualitative data identified barriers to rehabilitation prescription completion, including 'seen as tick-box exercise','not a priority', lack of resources (IT and workforce), poor inter-service communication, limited knowledge/training. Facilitators included therapist buy-in, standardised training, easy inter-service rehabilitation prescription transfer, usefulness for sharing patient needs.

CONCLUSIONS

Although rehabilitation prescriptions are valued by some service providers, their effectiveness is hindered by negative attitudes, limited knowledge and poor communication. Uncertainties exist about whether rehabilitation prescriptions achieve their goals, particularly in documenting patient needs, engaging patients in rehabilitation, and informing onward referrals following MTC discharge. Improving IT systems, empowering patients, redirecting funding, and providing training might improve their usage. Further research should explore service provider and patient perspectives, and prospective long-term follow-up on outcomes of rehabilitation prescription recommendations.

Duration of sick leave after operated and non-operated distal radial fracture: a Finnish cohort study of 19,995 patients

The purpose of this study was to investigate whether operative treatment for distal radial fracture reduces the length of sick leave and the costs of treatment. We identified 19,995 patients from a registry who received a state sick leave allowance between 2010 and 2019 owing to distal radial fractures. We compared these patients to a registry of operations and identified 4346 operated patients. Operated patients had a mean sick leave of 75 days, whereas non-operated patients had a sick leave of 63 days. In the operated group, the cost of sick leave was €7505 (UK£6419; US$8070), which was 34% higher than in the non-operated group. Over the analysed period, the duration of sick leave decreased. Although several studies have shown better early functional outcomes after operation, this does not seem to shorten sick leave.Level of evidence: III.

Health disparities in orthopedic trauma: a qualitative study examining providers' perspectives on barriers to care and recovery outcomes

Social workers involved in interdisciplinary orthopedic trauma care can benefit from the knowledge of providers' perspectives on healthcare disparities in this field. Using qualitative data from focus groups conducted on 79 orthopedic care providers at three Level 1 trauma centers, we assessed their perspectives on orthopedic trauma healthcare disparities and discussed potential solutions. Focus groups originally aimed to detect barriers and facilitators of the implementation of a trial of a live video mind-body intervention to aid in recovery in orthopedic trauma care settings (Toolkit for Optimal Recovery-TOR). We used the Socio-Ecological Model to analyze an emerging code of "health disparities" during data analysis to determine at which levels of care these disparities occurred. We identified factors related to health disparities in orthopedic trauma care and outcomes at the Individual (Education- comprehension, health-literacy; Language Barriers; Psychological Health- emotional distress, alcohol/drug use, learned helplessness; Physical Health- obesity, smoking; and Access to Technology), Relationship (Social Support Network), Community (Transportation and Employment Security), and Societal level (Access- safe/clean housing, insurance, mental health resources; Culture). We discuss the implications of the findings and provide recommendations to address these issues, with a specific focus on their relevance to the field of social work in health care.

Factors associated with discharge destination from acute care after moderate-to-severe traumatic injuries in Norway: a prospective population-based study

BACKGROUND

Previous studies have demonstrated that the trauma population has needs for rehabilitation services that are best provided in a continuous and coordinated way. The discharge destination after acute care is the second step to ensuring quality of care. There is a lack of knowledge regarding the factors associated with the discharge destination for the overall trauma population. This paper aims to identify sociodemographic, geographical, and injury-related factors associated with discharge destination following acute care at trauma centers for patients with moderate-to-severe traumatic injuries.

METHODS

A multicenter, population-based, prospective study was conducted with patients of all ages with traumatic injury [New Injury Severity Score (NISS) > 9] admitted within 72 h after the injury to regional trauma centers in southeastern and northern Norway over a 1-year period (2020).

RESULTS

In total, 601 patients were included; a majority (76%) sustained severe injuries, and 22% were discharged directly to specialized rehabilitation. Children were primarily discharged home, and most of the patients ≥ 65 years to their local hospital. Depending on the centrality of their residence [Norwegian Centrality Index (NCI) 1-6, where 1 is most central], we found that patients residing in NCI 3-4 and 5-6 areas sustained more severe injuries than patients residing in NCI 1-2 areas. An increase in the NISS, number of injuries, or a spinal injury with an Abbreviated Injury Scale (AIS) ≥ 3 was associated with discharge to local hospitals and specialized rehabilitation than to home. Patients with an AIS ≥ 3 head injury (RRR 6.1, 95% Confidence interval 2.80-13.38) were significantly more likely to be discharged to specialized rehabilitation than patients with a less severe head injury. Age < 18 years was negatively associated with discharge to a local hospital, while NCI 3-4, preinjury comorbidity, and increased severity of injuries in the lower extremities were positively associated.

CONCLUSIONS

Two-thirds of the patients sustained severe traumatic injury, and 22% were discharged directly to specialized rehabilitation. Age, centrality of the residence, preinjury comorbidity, injury severity, length of hospital stay, and the number and specific types of injuries were factors that had the greatest influence on discharge destination.

Health-related quality of life 12 years after injury: prevalence and predictors of outcomes in a cohort of injured Māori

PURPOSE

Studies have found that many people who sustain an injury can experience adverse outcomes for a considerable time thereafter. Māori, the Indigenous peoples of Aotearoa me Te Waipounamu (New Zealand; NZ), are no exception. The Prospective Outcomes of Injury Study (POIS) found that almost three-quarters of Māori participants were experiencing at least one of a range of poor outcomes at two years post-injury. The aim of this paper was to estimate the prevalence, and identify predictors, of adverse health-related quality of life (HRQoL) outcomes in the POIS-10 Māori cohort, 12 years after participants sustained an injury.

METHODS

Interviewers reached 354 individuals who were eligible to participate in a POIS-10 Māori interview, to be conducted a decade after the last phase of POIS interviews (held 24 months post-injury). The outcomes of interest were responses to each of the five EQ-5D-5L dimensions at 12 years post-injury. Potential predictors (i.e., pre-injury sociodemographic and health measures; injury-related factors) were collected from earlier POIS interviews. Additional injury-related information was collected from administrative datasets proximate to the injury event 12 years prior.

RESULTS

Predictors of 12-year HRQoL outcomes varied by EQ-5D-5L dimension. The most common predictors across dimensions were pre-injury chronic conditions and pre-injury living arrangements.

CONCLUSION

An approach to rehabilitation where health services proactively enquire about, and consider the broader aspects of, patient health and wellbeing throughout the injury recovery process, and effectively coordinate their patients' care with other health and social services where necessary, may help improve long-term HRQoL outcomes for injured Māori.

Psychological distress 12 years following injury in New Zealand: findings from the Prospective Outcomes of Injury Study-10 years on (POIS-10)

BACKGROUND

Injuries can have detrimental impacts on mental health, even after physical recovery. In our Prospective Outcomes of Injury Study (POIS), 25% of participants experienced psychological distress (assessed using the Kessler 6) three months after a sentinel injury event (SIE), declining to 16% at 24 months post-SIE. Internationally, studies of hospitalised patients found distress persisted beyond 24 months post-injury and remained higher than the general population. However, most studies only assessed distress at one timepoint, relied on long-term recall, or were limited to small samples or specific injury types. Therefore, we aim to describe the prevalence of psychological distress 12 years post-SIE and to investigate pre-injury, injury-related and early post-injury characteristics associated with long-term distress.

METHODS

POIS is a longitudinal cohort study of 2856 New Zealanders injured between 2007 and 2009, who were on the national injury insurer, Accident Compensation Corporation entitlement claims' register. Of these, 2068 POIS participants completed an interview at 24 months and agreed to further contact. They were invited to a follow-up interview 12 years post-SIE which included the Kessler-6 (K6), the psychological distress outcome of interest. Data about a range of pre-injury, injury-related and early (3 months) post-injury characteristics were collected via earlier interviews or administrative data sources (e.g. hospital discharge data).

RESULTS

Twelve years post-SIE, 1543 (75%) people were re-interviewed and 1526 completed the K6; n = 177 (12%) reported psychological distress. Multivariable modified Poisson regression models found pre-injury characteristics were associated with an increased risk of clinically relevant distress at 12 years, i.e. having inadequate income, identifying as Māori, Pacific or Asian and having one mental health condition. Early post-injury psychological distress and dissatisfaction with social relationships also increased risk. However, being older was associated with a reduced risk of distress.

CONCLUSION

Clinically relevant distress persists long-term post-injury among adults with varying injury severity, types and causes, and at higher prevalence than in the general population. Early identification of injured people at risk of long-term psychological distress provides opportunities for timely interventions to reduce psychological distress.

Psychological and psychosocial aspects of major trauma care: A survey of current practice across UK and Ireland

Introduction

Psychological and psychosocial impacts of major trauma, defined as any injury that has the potential to be life-threatening and/or life changing, are common, far-reaching and often enduring. There is evidence that these aspects of major trauma care are often underserved. The aim of this research was to gain insight into the current provision and operationalisation of psychological and psychosocial aspects of major trauma care across the UK and Ireland.

Methods

A cross-sectional online survey, open to health professionals working in major trauma network hospitals was undertaken. The survey had 69 questions across six sections: Participant Demographics, Psychological First Aid, Psychosocial Assessment and Care, Assessing and Responding to Distress, Clinical Psychology Services, and Major Trauma Keyworker (Coordinator) Role.

Results

There were 102 respondents from across the regions and from a range of professional groups. Survey findings indicate a lack of formalised systems to assess, respond and evaluate psychological and psychosocial aspects of major trauma care, most notably for patients with lower-level distress and psychosocial support needs, and for trauma populations that don't reach threshold for serious injury or complex health need. The findings highlight the role of major trauma keyworkers (coordinators) in psychosocial aspects of care and that although major trauma clinical psychology services are increasingly embedded, many lack the capacity to meet demand.

Conclusion

Neglecting psychological and psychosocial aspects of major trauma care may extend peritraumatic distress, result in preventable Years Lived with Disability and widen post-trauma health inequalities. A stepped psychological and psychosocial care pathway for major trauma patients and their families from the point of injury and continuing as they move through services towards recovery is needed. Research to fulfil knowledge gaps to develop and implement such a model for major trauma populations should be prioritised along with the development of corresponding service specifications for providers.

Cost-of-Illness Analysis of Long-Term Health Care Resource Use and Disease Burden in Patients With Pulmonary Embolism: Insights From the PREFER in VTE Registry

Background As mortality from pulmonary embolism (PE) decreases, the personal and societal costs among survivors are receiving increasing attention. Detailing this burden would support an efficient public health resource allocation. We aimed to provide estimates for the economic and disease burden of PE also accounting for long-term health care use and both direct and indirect costs beyond the acute phase. Methods and Results This is a cost-of-illness analysis with a bottom-up approach based on data from the PREFER in VTE registry (Prevention of Thromboembolic Events-European Registry in Venous Thromboembolism). We calculated direct (clinical events and anticoagulation) and indirect costs (loss of productivity) of an acute PE event and its 12-month follow-up in 2020 Euros. We estimated a disability weight for the 12-month post-PE status and corresponding disability adjusted life years presumably owing to PE. Disease-specific costs in the first year of follow-up after an incident PE case ranged between 9135 Euros and 10 620 Euros. The proportion of indirect costs was 42% to 49% of total costs. Costs were lowest in patients with ongoing cancer, mainly because productivity loss was less evident in this already burdened population. The calculated disability weight for survivors who were cancer free 12 months post-PE was 0.017, and the estimated disability adjusted life years per incident case were 1.17. Conclusions The economic burden imposed by PE to society and affected patients is considerable, and productivity loss is its main driver. The disease burden from PE is remarkable and translates to the loss of roughly 1.2 years of healthy life per incident PE case.

Psychological and psychosocial aspects of major trauma care in the United Kingdom: A scoping review of primary research

Introduction

More people are surviving major trauma, often with life changing injuries. Alongside physical injury, many survivors of major trauma experience psychological and psychosocial impacts. Presently, there is little guidance at the UK national level for psychological and psychosocial aspects of major trauma care. Set in the context of the regional model of major trauma care implemented in the UK in 2012, the purpose of this review was to identify and bring together primary research about psychological and psychosocial aspects of major trauma care in the UK to produce an overview of the field to date, identify knowledge gaps and set research priorities.

Methods

A scoping review was undertaken. Seven electronic databases (MEDLINE, Cochrane Library, CINAHL, Embase, PsycINFO, SocINDEX with Full Text and PROSPERO) were searched alongside a targeted grey literature search. Data from included studies were extracted using a predefined extraction form and underwent bibliometric analysis. Included studies were then grouped by type of research, summarised, and synthesised to produce a descriptive summary and overview of the field.

Results

The searches identified 5,975 articles. Following screening, 43 primary research studies were included in the scoping review. The scoping review, along with previous research, illustrates that psychological and psychosocial impacts are to be expected following major trauma. However, it also found that these aspects of care are commonly underserved and that there are inherent inequities across major trauma care pathways in the UK.

Conclusion

Though the scoping review identified a growing body of research investigating psychological and psychosocial aspects of major trauma care pathways in the UK, significant gaps in the evidence base remain. Research is needed to establish clinically effective psychological and psychosocial assessment tools, corresponding interventions, and patient-centred outcome measures so that survivors of major trauma (and family members or carers) receive the most appropriate care and intervention.

A systematic literature review of disability weights measurement studies: evolution of methodological choices

Background

The disability weight is an essential factor to estimate the healthy time that is lost due to living with a certain state of illness. A 2014 review showed a considerable variation in methods used to derive disability weights. Since then, several sets of disability weights have been developed. This systematic review aimed to provide an updated and comparative overview of the methodological design choices and surveying techniques that have been used in disability weights measurement studies and how they evolved over time.

Methods

A literature search was conducted in multiple international databases (early-1990 to mid-2021). Records were screened according to pre-defined eligibility criteria. The quality of the included disability weights measurement studies was assessed using the Checklist for Reporting Valuation Studies (CREATE) instrument. Studies were collated by characteristics and methodological design approaches. Data extraction was performed by one reviewer and discussed with a second.

Results

Forty-six unique disability weights measurement studies met our eligibility criteria. More than half (n = 27; 59%) of the identified studies assessed disability weights for multiple ill-health outcomes. Thirty studies (65%) described the health states using disease-specific descriptions or a combination of a disease-specific descriptions and generic-preference instruments. The percentage of studies obtaining health preferences from a population-based panel increased from 14% (2004–2011) to 32% (2012–2021). None of the disability weight studies published in the past 10 years used the annual profile approach. Most studies performed panel-meetings to obtain disability weights data.

Conclusions

Our review reveals that a methodological uniformity between national and GBD disability weights studies increased, especially from 2010 onwards. Over years, more studies used disease-specific health state descriptions in line with those of the GBD study, panel from general populations, and data from web-based surveys and/or household surveys. There is, however, a wide variation in valuation techniques that were used to derive disability weights at national-level and that persisted over time.

Prevalence and predictors of psychological distress following injury: findings from a prospective cohort study

BACKGROUND

Research examining psychological distress in people who have experienced an injury has focused on those with serious injuries or specific injury types, and has not involved long-term follow up. The aims of this investigation were to describe the prevalence of, and factors contributing to, psychological distress in a cohort of people with a broad range of injuries.

METHODS

The Prospective Outcomes of Injury Study (POIS) is a longitudinal cohort study of 2856 injured New Zealanders recruited from a national insurance entitlement claims register between 2007 and 2009. Participants were interviewed approximately 3, 12, and 24 months after their injury. The Kessler Psychological Distress Scale (K6) was used to measure psychological distress at each interview.

RESULTS

25% of participants reported clinically relevant distress (K6 ≥ 8) 3 months post-injury, 15% reported distress at 12 months, and 16% reported distress at 24 months. Being 45 years or older, Māori or Pacific ethnicity, experiencing pre-injury mental health conditions, having inadequate pre-injury income, reporting poor pre-injury health or trouble accessing healthcare, having a severe injury or an injury resulting from assault, and reporting clinically relevant distress 3 months post-injury were independently associated with an increased risk of distress 12 months post-injury. The majority of these associations were also evident with respect to distress 24 months post-injury.

CONCLUSIONS

Distress is common after injury among people with a broad range of injury types and severities. Screening for distress early after injury is important to identify individuals in need of targeted support.

Long-term medical and productivity costs of severe trauma: Results from a prospective cohort study

Background

Through improvements in trauma care there has been a decline in injury mortality, as more people survive severe trauma. Patients who survive severe trauma are at risk of long-term disabilities which may place a high economic burden on society. The purpose of this study was to estimate the health care and productivity costs of severe trauma patients up to 24 months after sustaining the injury. Furthermore, we investigated the impact of injury severity level on health care utilization and costs and determined predictors for health care and productivity costs.

Methods

This prospective cohort study included adult trauma patients with severe injury (ISS≥16). Data on in-hospital health care use, 24-month post-hospital health care use and productivity loss were obtained from hospital registry data and collected with the iMTA Medical Consumption and Productivity Cost Questionnaire. The questionnaires were completed 1 week and 1, 3, 6, 12 and 24 months after injury. Log-linked gamma generalized linear models were used to investigate the drivers of health care and productivity costs.

Results

In total, 174 severe injury patients were included in this study. The median age of participants was 55 years and the majority were male (66.1%). The mean hospital stay was 14.2 (SD = 13.5) days. Patients with paid employment returned to work 21 weeks after injury. In total, the mean costs per patient were €24,760 with in-hospital costs of €11,930, post-hospital costs of €7,770 and productivity costs of €8,800. Having an ISS ≥25 and lower health status were predictors of high health care costs and male sex was associated with higher productivity costs.

Conclusions

Both health care and productivity costs increased with injury severity, although large differences were observed between patients. It is important for decision-makers to consider not only in-hospital health care utilization but also the long-term consequences and associated costs related to rehabilitation and productivity loss.

Prospective Outcomes of Injury Study 10 Years on (POIS-10): An Observational Cohort Study

Injury is a leading cause of disability and is costly. This prospective cohort study extension aims to improve disability, health, and wellbeing outcomes for injured New Zealanders, including for Māori. We will identify predictors and modifiable risk factors of long-term outcomes (positive and negative), and develop an Injury Early Care Tool (INJECT) to inform the implementation of effective interventions to improve outcomes. In the Prospective Outcomes of Injury Study (POIS), 2856 people participated following an injury (occurring between 2007 and 2009) registered with New Zealand's no-fault accident compensation scheme (ACC). POIS-10 will invite 2121 people (including 358 Māori) who completed a 24-month POIS interview and agreed to follow-up, anticipating 75% participation (n = 1591). Interviews will collect sociodemographic characteristics, life events, comorbidities, and new injuries since participants' 24-month interview, as well as key disability, health, and wellbeing outcomes 12 years post-injury. Injury-related data will be collected from ACC and hospitalisation records 12 years post-injury. Regression models for the main outcomes will examine the direct effects of predictor variables after adjustment for a wide range of confounders. POIS-10 is enhanced by our partnership with ACC, and expert advisors and will benefit injured people, including Māori, through increased understanding of mechanisms and interventions to improve long-term post-injury outcomes.

Quantification of injury burden using multiple data sources: a longitudinal study

Quantification of injury burden is vital for injury prevention, as it provides a guide for setting policies and priorities. This study generated a set of Hong Kong specific disability weights (DWs) derived from patient experiences and hospital records. Patients were recruited from the Accident and Emergency Department (AED) of three major trauma centers in Hong Kong between September 2014 and December 2015 and subsequently interviewed with a focus on health-related quality of life at most three times over a 12-month period. These patient-reported data were then used for estimation of DWs. The burden of injury was determined using the mortality and inpatient data from 2001 to 2012 and then compared with those reported in the UK Burden of Injury (UKBOI) and global burden of diseases (GBD) studies. There were 22,856 mortality cases and 817,953 morbidity cases caused by injuries, in total contributing to 1,027,641 disability-adjusted life years (DALYs) in the 12-year study timeframe. Estimates for DALYs per 100,000 in Hong Kong amounted to 1192, compared with 2924 in UKBOI and 3459 in GBD. Our findings support the use of multiple data sources including patient-reported data and hospital records for estimation of injury burden.

Vocational rehabilitation to enhance return to work after trauma (ROWTATE): protocol for a non-randomised single-arm mixed-methods feasibility study

Background

Traumatic injuries are common amongst working-age adults. Survivors often experience physical and psychological problems, reduced quality of life and difficulty returning to work. Vocational rehabilitation improves work outcomes for a range of conditions but evidence of effectiveness for those with traumatic injuries is lacking. This study assesses feasibility of delivering a vocational rehabilitation intervention to enhance return to work and improve quality of life and wellbeing in people with at least moderate trauma to inform design of a definitive randomised controlled trial (RCT).

Methods

Non-randomised, single-arm, multi-centre mixed-methods feasibility study with nested case studies and qualitative study. The case studies comprise interviews, observations of clinical contacts and review of clinical records. The qualitative study comprises interviews and/or focus groups. Participants will be recruited from two UK major trauma centres. Participants will comprise 40 patients aged 16–69 with an injury severity score of > 8 who will receive the intervention and complete questionnaires. Interviews will be conducted with 10 patients and their occupational therapists (OTs), clinical psychologists (CPs), employers and commissioners of rehabilitation services. Fidelity will be assessed in up to six patients by observations of OT and CP—patient contacts, review of patient records and intervention case report forms. OT and CP training will be evaluated using questionnaires and competence to deliver the intervention assessed using a team objective structured clinical examination and written task. Patients participating in and those declining participation in the study will be invited to take part in interviews/focus groups to explore barriers and facilitators to recruitment and retention. Outcomes include recruitment and retention rates, intervention fidelity, OT and CP competence to deliver the intervention, experiences of delivering or receiving the intervention and factors likely to influence definitive trial delivery.

Discussion

Effective vocational rehabilitation interventions to enhance return to work amongst trauma patients are urgently needed because return to work is often delayed, with detrimental effects on health, financial stability, healthcare resource use and wider society. This protocol describes a feasibility study delivering a complex intervention to enhance return to work in those with at least moderate trauma.

Comparison of three different methods to estimate the burden of disease of burn injuries in Western Australia in 2011-2018

BACKGROUND

Priority setting and resource allocation in health care, surveillance and interventions is based increasingly on burden of disease. Several methods exist to calculate the non-fatal burden of disease of burns expressed in years lived with disability (YLDs). The aim of this study was to assess the burden of disease due to burns in Western Australia 2011-2018 and compare YLD outcomes between three existing methods.

METHODS

Data from the Burns Service of Western Australia was used. Three existing methods to assess YLDs were compared: the Global Burden of Disease (GBD) method, a method dedicated to assess injury YLDs (Injury-VIBES), and a method dedicated to assess burns YLDs (INTEGRIS-burns).

RESULTS

Incidence data from 2,866 burn patients were used. Non-fatal burden of disease estimates differed substantially between the different methods. Estimates for 2011-2018 ranged between 610 and 1,085 YLDs per 100.000 based on the Injury-VIBES method; between 209 and 324 YLDs based on the INTEGRIS-burns method; and between 89 and 120 YLDs based on the GBD method. YLDs per case were three to nine times higher when the Injury-VIBES method was applied compared to the other methods. Also trends in time differed widely through application of the different methods. There was a strong increase in YLDs over the years when the Injury-VIBES method was applied, a slight increase when the INTEGRIS-burns method was applied and a stable pattern when the GBD method was applied.

CONCLUSION

This study showed that the choice for a specific method heavily influences the non-fatal burden of disease expressed in YLDs, both in terms of annual estimates as well as in trends over time. By addressing the methodological limitations evident in previously published calculations of the non-fatal burden of disease, the INTEGRIS-burns seems to present a method to provide the most robust estimates to date, as it is the only method adapted to the nature of burn injuries and their recovery.

A systematic review of studies measuring health-related quality of life of general injury populations: update 2010-2018

Background

Studies examining the impact of injury on health-related quality of life (HRQL) over time are necessary to understand the short- and long-term consequences of injury for population health. The aim of this systematic review was to provide an evidence update on studies that have measured HRQL over time in general injury populations using a generic (general) health state measure.

Methods

Studies conducted between 2010 and 2018 that assessed HRQL at more than one time point among general injury populations were eligible for inclusion. Two reviewers independently extracted information from each study on design, HRQL measure used, method of HRQL measure administration, timing of assessment(s), predictive variables, ability to detect change, and findings. Quality appraisals of each study were also completed by two reviewers using items from the RTI Item Bank on Risk of Bias and Precision of Observational Studies and the Guidelines for the Conduction of Follow-up Studies Measuring Injury-Related Disability.

Results

Twenty-nine studies (44 articles) that met the inclusion criteria were identified. HRQL was measured using 14 different generic measures; the SF-36, SF-12, and EQ-5D were used most frequently. A varying number of follow-up assessments were undertaken, ranging from one to five. Follow-up often occurred 12 months post-injury. Fewer studies (n = 11) examined outcomes two or more years post-injury, and only one to 10 years post-injury. While most studies documented improvements in HRQL over time since the injury event, study populations had not returned to pre-injury status or reached general population norm HRQL values at post-injury follow-ups.

Conclusions

Since 2010 there has been a substantial increase in the number of studies evaluating the HRQL of general injury populations. However, significant variability in study design continues to impede quantification of the impact of injury on population health over time. Variation between studies is particularly evident with respect to timing and number of follow-up assessments, and selection of instruments to evaluate HRQL.

Trauma-associated acute kidney injury

PURPOSE OF REVIEW

A summary of recent research into the epidemiology, cause, management and outcomes of trauma-associated acute kidney injury (AKI). There is an increasing focus on subtypes of AKI to better target clinical management and future research.

RECENT FINDINGS

AKI associated with trauma occurs in 20-24% of patients admitted to ICU. On the basis of creatinine and/or urine output, AKI occurs in the first few days of traumatic illness. Although various associations have been identified, shock and high-volume blood transfusion are the most consistent risks for development of trauma-associated AKI. Short-term outcomes appear worse for patients with AKI, but extent of longer term kidney function recovery remains unknown. Recent research in the general critical care population is beginning to better inform AKI management; however, currently, preventive and supportive strategies remain the mainstay of AKI management after trauma.

SUMMARY

Well-designed, prospective research is required to better understand the phenotype, pathophysiology and recovery trajectory of trauma-associated AKI. Only then can potentially unique therapeutic targets be developed for this common subtype of AKI.

Health status and psychological outcomes after trauma: A prospective multicenter cohort study

Introduction

Survival after trauma has considerably improved. This warrants research on non-fatal outcome. We aimed to identify characteristics associated with both short and long-term health status (HS) after trauma and to describe the recovery patterns of HS and psychological outcomes during 24 months of follow-up.

Methods

Hospitalized patients with all types of injuries were included. Data were collected at 1 week 1, 3, 6, 12, and 24 months post-trauma. HS was assessed with the EuroQol-5D-3L (EQ-5D-3L) and the Health Utilities Index Mark 2 and 3 (HUI2/3). For the screening of symptoms of post-traumatic stress, anxiety and depression, the Impact of Event Scale (IES) and the Hospital Anxiety and Depression Scale (HADS) subscale anxiety (HADSA) and subscale depression (HADSD) were used. Recovery patterns of HS and psychological outcomes were examined with linear mixed model analyses.

Results

A total of 4,883 patients participated (median age 68 (Interquartile range 53–80); 50% response rate). The mean (Standard Deviation (SD)) pre-injury EQ-5D-3L score was 0.85 (0.23). One week post-trauma, mean (SD) EQ-5D-3L, HUI2 and HUI3 scores were 0.49 (0.32), 0.61 (0.22) and 0.38 (0.31), respectively. These scores significantly improved to 0.77 (0.26), 0.77 (0.21) and 0.62 (0.35), respectively, at 24 months. Most recovery occurred up until 3 months. At long-term follow-up, patients of higher age, with comorbidities, longer hospital stay, lower extremity fracture and spine injury showed lower HS. The mean (SD) scores of the IES, HADSA and HADSD were respectively 14.80 (15.80), 4.92 (3.98) and 5.00 (4.28), respectively, at 1 week post-trauma and slightly improved over 24 months post-trauma to 10.35 (14.72), 4.31 (3.76) and 3.62 (3.87), respectively.

Discussion

HS and psychological symptoms improved over time and most improvements occurred within 3 months post-trauma. The effects of severity and type of injury faded out over time. Patients frequently reported symptoms of post-traumatic stress.

Can Patient Reported Outcomes (PROs) from Population Surveys Provide Accurate Estimates of Pre-Admission Health Status of Emergency Hospital Admissions?

INTRODUCTION

The use of PROs for assessing the outcomes of emergency hospital admissions requires a means of estimating patients' pre-admission health status. A possible alternative to asking patients to recall how their health was before the incident causing admission is to use estimates derived from matched samples from population surveys. Our aims were to explore the impact of different methods of matching and to compare the results with estimates based on retrospective reporting.

METHODS

First, elective hip arthroplasty patients were matched to respondents to the General Practice Patient Survey using age, sex, socio-economic status and number of comorbidities. The impact of restricting matching for locality and specific co-morbidities was explored. Second, the best matching method was applied to emergency admissions for laparotomy and for percutaneous coronary intervention (PCI) after acute myocardial infarction. Data were stratified by patient characteristics. Differences in mean EQ-5D scores between the patients and matched population respondents were tested using t tests.

RESULTS

Modifying the most basic form of matching by also taking locality and the specific comorbid conditions into account made no significant difference to the mean EQ-5D score for hip arthroplasty patients. Even using the most detailed matching possible, patients' mean EQ-5D score was significantly different to that of the general population for all three cohorts. The difference was greatest for elective hip arthroplasty (0.22 v 0.64), less so for emergency laparotomy (0.56 v 0.72) and least for PCI (0.79 v 0.71). This reflects hip arthroplasty patients having a long-standing condition characterised by pain and limited mobility, whereas the other two cohorts may have enjoyed reasonable health until an unexpected acute episode led to their emergency admission.

CONCLUSION

Routine PRO data acquired from population surveys cannot be used as an accurate alternative to retrospectively reported PROMs by patients during their emergency admission episode.

Comparison of revised Functional Capacity Index scores with Abbreviated Injury Scale 2008 scores in predicting 12-month severe trauma outcomes

INTRODUCTION

Anatomical injury as measured by the AIS often accounts for only a small proportion of variability in outcomes after injury. The predictive Functional Capacity Index (FCI) appended to the 2008 AIS claims to provide a widely available method of predicting 12-month function following injury.

OBJECTIVES

To determine the extent to which AIS-based and FCI-based scoring is able to add to a simple predictive model of 12-month function following severe injury.

METHODS

Adult trauma patients were drawn from the population-based Victorian State Trauma Registry. Major trauma and severely injured orthopaedic trauma patients were followed up via telephone interview including Glasgow Outcome Scale-Extended, the EQ-5D-3L and return to work status. A battery of AIS-based and FCI-based scores, and a simple count of AIS-coded injuries were added in turn to a base model using age and gender.

RESULTS

A total of 20 813 patients survived to 12 months and had at least one functional outcome recorded, representing 85% follow-up. Predictions using the base model varied substantially across outcome measures. Irrespective of the method used to classify the severity of injury, adding injury severity to the model significantly, but only slightly improved model fit. Across the outcomes evaluated, no method of injury severity assessment consistently outperformed any other.

CONCLUSIONS

Anatomical injury is a predictor of trauma outcome. However, injury severity as described by the FCI does not consistently improve discrimination, or even provide the best discrimination compared with AIS-based severity scores or a simple injury count.

Prevalence and predictors of injuries in Kenya: findings from the national STEPs survey

BACKGROUND

Injuries are becoming an increasingly important public health challenge globally, and are responsible for 9% of deaths. Beyond their impact on health and well-being, fatal and non-fatal injuries also affect social and economic development for individuals concerned. Kenya has limited data on the magnitude and factors associated with injuries. This study sought to determine the magnitude and risk factors for injuries in Kenya and to identify where the largest burden lies.

METHODS

A national population-based household survey was conducted from April-June 2015 among adults age 18-69 years. A three-stage cluster sample design was used to select clusters, households and eligible individuals based on WHO guidelines. We estimated the prevalence of injuries, identified factors associated with injuries and the use of protective devices/practices among road users. Multivariate logistic regression was used to identify potential factors associated with injuries.

RESULTS

A total of 4484 adults were included in the study. Approximately 15% had injuries from the past 12 months, 60.3% were males. Four percent of the respondents had been injured in a road traffic crash, 10.9% had experienced unintentional injuries other than road traffic injuries while 3.7% had been injured in violent incidents. Among drivers and passengers 12.5% reported always using a seatbelt and 8.1% of the drivers reported driving while drunk. The leading causes of injuries other than road traffic crashes were falls (47.6%) and cuts (34.0%). Males (p = 0.001), age 18-29 (p < 0.05) and smokers (p = 0.001) were significantly more likely to be injured in a road traffic crash. A higher social economic status (p = 0.001) was protective against other unintentional injuries while students had higher odds for such types of injuries. Heavy episodic drinking (p = 0.001) and smoking (p < 0.05) were associated with increased likelihood of occurrence of a violent injury.

CONCLUSIONS

Our study found that male, heavy episodic drinkers, current smokers and students were associated with various injury types. Our study findings highlight the need to scale up interventions for injury prevention for specific injury mechanisms and target groups. There is need for sustained road safety mass media campaigns and strengthened enforcement on helmet wearing, seatbelt use and drink driving.

Feasibility of collecting and assessing patient-reported outcomes for emergency admissions: laparotomy for gastrointestinal conditions

INTRODUCTION

Audit of emergency surgery is usually limited to immediate clinical outcomes relating to outcomes during the acute hospital episode with little attempt to capture patients' views of their longer-term outcomes. Our aim was to determine the response rate to patient-reported outcome measures (PROMs) for patients who underwent an emergency laparotomy for gastrointestinal conditions, identify response bias and explore the feasibility of comparing outcomes with their prior health based on their recalled view collected during their admission.

METHODS

Patients undergoing emergency laparotomy in 11 hospitals were recruited to complete a retrospective questionnaire containing the EQ-5D-3L and Gastrointestinal Quality of Life Index (GIQLI). Response rate for 3-month mailed follow-up questionnaire and potential response biases were assessed. Patients' outcomes were compared with their baseline using χ2 and paired t-test to assess for differences.

RESULTS

Of 255 patients contacted at 3 months, 190 (74.1%) responded. Responders were more likely to be older, female and more affluent. Patients' health improved significantly as regards the GIQLI (93.3 vs 97.9; p=0.048) and the subscale on symptoms (51.9 vs 59.6; p<0.001). No significant change in subscales on emotion or physical aspects or for overall health status (EQ-5D: 0.58 vs 0.64; p=0.06). According to the social subscale, patients had deteriorated (11.0 vs 9.8; p<0.0006). Differences in change scores by patient characteristics were slight, suggesting minimal response bias.

CONCLUSION

This approach offers the opportunity for assessing the impact of treatment, from the patient's perspective and the potential to evaluate emergency laparotomy care using PROMs.

Validating injury burden estimates using population birth cohorts and longitudinal cohort studies of injury outcomes: the VIBES-Junior study protocol

INTRODUCTION

Traumatic injury is a leading contributor to the global disease burden in children and adolescents, but methods used to estimate burden do not account for differences in patterns of injury and recovery between children and adults. A lack of empirical data on postinjury disability in children has limited capacity to derive valid disability weights and describe the long-term individual and societal impacts of injury in the early part of life. The aim of this study is to establish valid estimates of the burden of non-fatal injury in children and adolescents.

METHODS AND ANALYSIS

Five longitudinal studies of paediatric injury survivors <18 years at the time of injury (Australia, Canada, UK and USA) and two whole-of-population linked administrative data paediatric studies (Australia and Wales) will be analysed over a 3-year period commencing 2018. Meta-analysis of deidentified patient-level data (n≈2,600) from five injury-specific longitudinal studies (Victorian State Trauma Registry; Victorian Orthopaedic Trauma Outcomes Registry; UK Burden of Injury; British Columbia Children's Hospital Longitudinal Injury Outcomes; Children's Health After Injury) and >1 million children from two whole-of-population cohorts (South Australian Early Childhood Data Project and Wales Electronic Cohort for Children). Systematic analysis of pooled injury-specific cohort data using a variety of statistical techniques, and parallel analysis of whole-of-population cohorts, will be used to develop estimated disability weights for years lost due to disability, establish appropriate injury classifications and explore factors influencing recovery.

ETHICS AND DISSEMINATION

The project was approved by the Monash University Human Research Ethics Committee project number 12 311. Results of this study will be submitted for publication in internationally peer-reviewed journals. The findings from this project have the capacity to improve the validity of paediatric injury burden measurements in future local and global burden of disease studies.

From Malawi to Middlesex: the case of the Arbutus Drill Cover System as an example of the cost-saving potential of frugal innovations for the UK NHS

Background

Musculoskeletal disease is one of the leading clinical and economic burdens of the UK health system, and the resultant demand for orthopaedic care is only set to increase. One commonly used and one of the most expensive hardware in orthopaedic surgery is the surgical drill and saw. Given financial constraints, the National Health Service (NHS) needs an economic way to address this recurring cost. We share evidence of one frugal innovation with potential for contributing to the NHS’ efficiency saving target of £22 billion by 2020.

Methods

Exploratory case study methodology was used to develop insights and understanding of the innovations potential for application in the NHS. Following a global search for potential frugal innovations in surgery, the Arbutus Drill Cover System was identified as an innovation with potential to deliver significant cost savings for the NHS in the UK.

Results

The Arbutus Drill Cover System is up to 94% cheaper than a standard surgical drill available in the UK. Clinical and laboratory tests show that performance, safety and usability are as good as current offerings in high-income countries and significantly better than hand drills typically used in low-and-middle-income countries. The innovation meets all regulatory requirements to be a medical device in the Europe and North America.

Conclusions

The innovation holds promise in reducing upfront and life span costs for core equipment used in orthopaedic surgery without loss of effectiveness or safety benchmarks. However, the innovation needs to navigate complicated and decentralised procurement processes and clinicians and healthcare leaders need to overcome cognitive bias.

Accident frequency and unrealistic optimism: Children's assessment of risk

Accidental injury is a major cause of mortality and morbidity among children, warranting research on their risk perceptions. Three hundred and seven children aged 10-11 years assessed the frequency, danger and personal risk likelihood of 8 accidents. Two social-cognitive biases were manifested. The frequency of rare accidents (e.g. drowning) was overestimated, and the frequency of common accidents (e.g. bike accidents) underestimated; and the majority of children showed unrealistic optimism tending to see themselves as less likely to suffer these accidents in comparison to their peers, offering superior skills or parental control of the environment as an explanation. In the case of pedestrian accidents, children recognised their seriousness, underestimated the frequency of this risk and regarded their own road crossing skill as protection. These findings highlight the challenging task facing safety educators who, when teaching conventional safety knowledge and routines, also need to alert children to the danger of over-confidence without disabling them though fear.

Postoperative weight bearing and patient reported outcomes at one year following tibial plateau fractures

Tibial plateau fractures are complex and the current evidence for postoperative rehabilitation is weak, especially related to the recommended postoperative weight bearing. The primary aim of this study was to investigate if loading in the first 12 weeks of recovery is associated with patient reported outcome measures at 26 and 52 weeks postoperative. We hypothesized that there would be no association between loading and patient reported outcome measures. Seventeen patients, with a minimum of 52-week follow-up following fragment-specific open reduction and internal fixation for tibial plateau fracture, were selected for this retrospective analysis. Postoperatively, patients were advised to load their limb to a maximum of 20kg during the first 6 weeks. Loading data were collected during walking using force platforms. A ratio of limb loading (affected to unaffected) was calculated at 2, 6 and 12 weeks postoperative. Knee Injury and Osteoarthritis Scores were collected at 6, 12, 26 and 52 weeks postoperative. The association between loading ratios and patient reported outcomes were investigated. Compliance with weight bearing recommendations and changes in the patient reported outcome measures are described. Fracture reduction and migration were assessed on plain radiographs. No fractures demonstrated any measurable postoperative migration at 52 weeks. Significant improvements were seen in all patient reported outcome measures over the first 52 weeks, despite poor adherence to postoperative weight bearing restrictions. There were no associations between weight bearing ratio and patient reported outcomes at 52 weeks postoperative. Significant associations were identified between the loading ratio at 2 weeks and knee-related quality of life at six months (R²=0.392), and between the loading ratio at 6 weeks combined with injury severity and knee-related quality of life at 26 weeks (R²=0.441). In summary, weight bearing as tolerated does not negatively affect the results of tibial plateau fracture and may therefore be safe for postoperative management. These findings should be taken in context of the sample size, which was not sufficient for sub-group analysis to investigate the role of impaction grafting.

Long-term health status and trajectories of seriously injured patients: A population-based longitudinal study

BACKGROUND

Improved understanding of the quality of survival of patients is crucial in evaluating trauma care, understanding recovery patterns and timeframes, and informing healthcare, social, and disability service provision. We aimed to describe the longer-term health status of seriously injured patients, identify predictors of outcome, and establish recovery trajectories by population characteristics.

METHODS AND FINDINGS

A population-based, prospective cohort study using the Victorian State Trauma Registry (VSTR) was undertaken. We followed up 2,757 adult patients, injured between July 2011 and June 2012, through deaths registry linkage and telephone interview at 6-, 12-, 24-, and 36-months postinjury. The 3-level EuroQol 5 dimensions questionnaire (EQ-5D-3L) was collected, and mixed-effects regression modelling was used to identify predictors of outcome, and recovery trajectories, for the EQ-5D-3L items and summary score. Mean (SD) age of participants was 50.8 (21.6) years, and 72% were male. Twelve percent (n = 333) died during their hospital stay, 8.1% (n = 222) of patients died postdischarge, and 155 (7.0%) were known to have survived to 36-months postinjury but were lost to follow-up at all time points. The prevalence of reporting problems at 36-months postinjury was 37% for mobility, 21% for self-care, 47% for usual activities, 50% for pain/discomfort, and 41% for anxiety/depression. Continued improvement to 36-months postinjury was only present for the usual activities item; the adjusted relative risk (ARR) of reporting problems decreased from 6 to 12 (ARR 0.87, 95% CI: 0.83-0.90), 12 to 24 (ARR 0.94, 95% CI: 0.90-0.98), and 24 to 36 months (ARR 0.95, 95% CI: 0.95-0.99). The risk of reporting problems with pain or discomfort increased from 24- to 36-months postinjury (ARR 1.06, 95% CI: 1.01, 1.12). While loss to follow-up was low, there was responder bias with patients injured in intentional events, younger, and less seriously injured patients less likely to participate; therefore, these patient subgroups were underrepresented in the study findings.

CONCLUSIONS

The prevalence of ongoing problems at 3-years postinjury is high, confirming that serious injury is frequently a chronic disorder. These findings have implications for trauma system design. Investment in interventions to reduce the longer-term impact of injuries is needed, and greater investment in primary prevention is needed.

Psychological morbidity and health-related quality of life after injury: multicentre cohort study

PURPOSE

To demonstrate the impact of psychological morbidity 1 month post-injury on subsequent post-injury quality of life (HRQoL) in a general injury population in the UK to inform development of trauma care and rehabilitation services.

METHODS

Multicentre cohort study of 16-70-year-olds admitted to 4 UK hospitals following injury. Psychological morbidity and HRQoL (EQ-5D-3L) were measured at recruitment and 1, 2, 4 and 12 months post-injury. A reduction in EQ-5D compared to retrospectively assessed pre-injury levels of at least 0.074 was taken as the minimal important difference (MID). Multilevel logistic regression explored relationships between psychological morbidity 1 month post-injury and MID in HRQoL over the 12 months after injury.

RESULTS

A total of 668 adults participated. Follow-up rates were 77% (1 month) and 63% (12 months). Substantial reductions in HRQoL were seen; 93% reported a MID at 1 month and 58% at 12 months. Problems with pain, mobility and usual activities were commonly reported at each time point. Depression and anxiety scores 1 month post-injury were independently associated with subsequent MID in HRQoL. The relationship between depression and HRQoL was partly explained by anxiety and to a lesser extent by pain and social functioning. The relationship between anxiety and HRQoL was not explained by factors measured in our study.

CONCLUSIONS

Hospitalised injuries result in substantial reductions in HRQoL up to 12 months later. Depression and anxiety early in the recovery period are independently associated with lower HRQoL. Identifying and managing these problems, ensuring adequate pain control and facilitating social functioning are key elements in improving HRQoL post-injury.

Two years after injury: prevalence and early post-injury predictors of ongoing injury-related problems

PURPOSE

To determine, in a cohort with injuries classified anatomically as mainly minor or moderate and for which only 25% were hospitalised acutely, the prevalence of ongoing problems attributed by participants to their injury 2 years prior, and to examine whether three-month post-injury experiences and expectations predict such problems.

METHODS

Participants (N = 2231; 18-64 years at injury) were those in the Prospective Outcomes of Injury Study who completed the initial three-month and final two-year interviews. The outcome measure was whether participants reported ongoing injury-related problems at 2 years. Possible early post-injury predictors were identified from the first interview; pre-injury and injury-related potential confounders from the first interview, insurer records and hospital discharge records. Multivariable models estimated relative risks.

RESULTS

Almost half the participants reported injury-related problems at 2 years. Participants reporting non-recovery at 3 months were more likely than those reporting recovery to have ongoing problems at 2 years, ranging from participants expecting to get better soon [adjusted RR 2.2, 95% CI (1.7,2.8)) to those expecting to never get better (aRR 3.1, 95% CI (2.4,4.0)]. Several three-month post-injury experiences also predicted ongoing problems at 2 years. Participants at highest risk included those with extreme pain [aRR 2.1, 95% CI (1.7,2.5)], and less involvement in usual activities [aRR 1.7, 95% CI (1.5,1.9)].

CONCLUSIONS

Findings indicate that early post-injury characteristics predict longer-term recovery among this cohort, most of who were not classified as seriously injured, and provide guidance for future studies on interventions to reduce poor outcome prevalence, particularly focussing on pain management and enabling return to independence and social participation.

Estimation of years lived with disability due to noncommunicable diseases and injuries using a population-representative survey

The Global Burden of Disease 2010 and the WHO Global Health Estimates of years lived with disability (YLDs) uses disability-weights obtained from lay health-state descriptions, which cannot fully reflect different disease manifestations, according to severity, treatment, and environment. The aim of this study was to provide population-representative YLDs of noncommunicable diseases and injuries using a prevalence-based approach, with the disability weight measured in subjects with specific diseases or injuries. We included a total of 44969 adults, who completed the EQ-5D questionnaire as participation in the Korea National Health and Nutrition Examination Survey 2007-2014. We estimated the prevalence of each of 40 conditions identified from the noncommunicable diseases and injuries in the WHO list. Modified condition-specific disability-weight was determined from the adjusted mean difference of the EQ-5D index between the condition and reference groups. Condition-specific YLDs were calculated as the condition's prevalence multiplied by the condition's disability-weight. All-cause YLDs, estimated as "number of population × (1 - mean score of EQ-5D)" were 2165 thousands in 39044 thousand adults aged ≥20. The combined YLDs for all 40 conditions accounted for 67.6% of all-cause YLDs, and were 1604, 2126, 8749, and 12847 per 100000 young (age 20-59) males, young females, old (age ≥60) males, and old females, respectively. Back pain/osteoarthritis YLDs were exceptionally large (442/40, 864/146, 2037/836, and 4644/3039 per 100000 young males, young females, old males, and old females, respectively). Back pain, osteoarthritis, depression, diabetes, periodontitis, and stroke accounted for 22.3%, 9.1%, 4.6%, 3.3%, 3.2%, and 2.9% of all-cause YLDs, respectively. In conclusion, this estimation of YLDs using prevalence rates and disability-weights measured in a population-representative survey may form the basis for population-level strategies to prevent age-related worsening of disability.

Higher mortality risk among injured individuals in a population-based matched cohort study

BACKGROUND

Improved understanding of long-term mortality attributable to injury is needed to accurately inform injury burden studies. This study aims to quantify and describe mortality attributable to injury 12 months after an injury-related hospitalisation in Australia.

METHOD

A population-based matched cohort study using linked hospital and mortality data from three Australian states during 2008-2010 was conducted. The injured cohort included individuals ≥18 years who had an injury-related hospital admission in 2009. A comparison cohort of non-injured people was obtain by randomly selecting from the electoral roll. This comparison group was matched 1:1 on age, gender and postcode of residence. Pre-index injury health service use and 12-month mortality were examined. Adjusted mortality rate ratios (MRR) and attributable risk were calculated. Cox proportional hazard regression was used to examine the effect of risk factors on survival.

RESULTS

Injured individuals were almost 3 times more likely to die within 12 months following an injury (MRR 2.90; 95% CI: 2.76-3.04). Individuals with a traumatic brain injury (MRR 7.58; 95% CI: 5.92-9.70) or injury to internal organs (MRR 7.38; 95% CI: 5.90-9.22) were 7 times more likely to die than the non-injured group. Injury was likely to be a contributory factor in 92% of mortality within 30 days and 66% of mortality at 12 months following the index injury hospital admission. Adjusted mortality rate ratios varied by type of cause-specific death, with MRR highest for injury-related deaths.

CONCLUSIONS

There are likely chronic consequences of sustaining a traumatic injury. Longer follow-up post-discharge is needed to consider deaths likely to be attributable to the injury. Better enumeration of long-term injury-related mortality will have the potential to improve estimates of injury burden.

Demographic profile and pattern of fatal injuries in Nairobi, Kenya, January-June 2014

Background

Violence and Injuries are a significant global public health concern characterized by marked regional variation in incidence. Approximately five million people die from injuries each year, accounting 9% of all deaths worldwide. In Kenya, injuries are increasingly becoming a cause of hospital admissions and mortality where they account for 10% of all the deaths. The objective of this study was to determine the magnitude, demographic profile and pattern of fatal injuries in Nairobi.

Methods

Retrospective review of death certificates from the Department of Civil Registration was done for deaths caused by injuries that occurred in Nairobi during the period, January to June 2014. Data was collected using a standardized form. Data entry, cleaning and analysis was done using Epi info version 7.0.

Results

A total of 11,443 records were reviewed. From this data, deaths resulting from injuries were 1,208 accounting for 10.6% of all recorded deaths. Majority of the deaths resulting from injuries occurred in persons aged 25 to 44 years (48.1%). Males accounted for 85% of all the injuries. The leading cause of injury was assault by blunt force at 30.5%, followed by road traffic injuries at 25.9% and fire arm injuries at 15%. Pre-hospital deaths accounted for 51.4% of all the deaths. Nineteen percent of the deaths resulting from injuries had autopsies performed on them.

Conclusion

Our study found that injuries are an important cause of fatality in Nairobi, accounting for one in ten deaths. There is need for multisectoral collaboration as some of the preventive measures that target the most prevalent injuries such as assault and road traffic injuries lie outside the health sector. There exists information gaps on the death certificates hence there is need to adequately capacity build both clinicians and death certifiers. There is also a need to revise the death certificates and to improve the pre-hospital care system for the injured persons.

Quantifying the hospitalised morbidity and mortality attributable to traumatic injury using a population-based matched cohort in Australia

OBJECTIVES

To quantify the 12-month hospitalised morbidity and mortality attributable to traumatic injury using a population-based matched cohort in Australia.

SETTING

New South Wales, Queensland and South Australia, Australia.

PARTICIPANTS

Individuals ≥18 years who had an injury-related hospital admission in 2009 formed the injured cohort. The non-injured comparison cohort was randomly selected from the electoral roll and was matched 1:1 on age, gender and postcode of residence at the date of the index injury admission of their matched counterpart.

PRIMARY OUTCOME MEASURES

Using linked emergency department presentation, hospital admission and mortality records from 1 January 2008 to 31 December 2010 for both the injured and non-injured cohorts, 12-month mortality and pre-index and post-index injury hospital service use was examined. Adjusted rate ratios and attributable risk were calculated.

RESULTS

There were 167 600 individuals injured in 2009 and admitted to hospital in New South Wales, South Australia or Queensland with a matched comparison. The injured cohort had 3 times higher proportion of having ≥1 comorbidity preinjury, higher preinjury hospital service use, and a higher 12-month mortality compared with a non-injured comparison group. The injured cohort had 2.20 (95% CI 2.12 to 2.28) times higher rate of hospital admissions in the 12 months post the index injury admission compared with the non-injured comparison cohort. Injury was a likely contributory factor in at least 55% of hospitalisations within 12 months of the index injury hospitalisation.

CONCLUSIONS

Individuals who had an injury-related hospitalisation had higher mortality and are hospitalised at increased rates for many months postinjury. While comorbid conditions are significant, they do not account for the differences in outcomes. This study contributes to informing research efforts on better quantifying the attributable burden of hospitalised injury-related disability and mortality in Australia.

Disability-Adjusted Life Years (DALYs) for Injuries Using Death Certificates and Hospital Discharge Survey by the Korean Burden of Disease Study 2012

A system for assessing the burdens imposed by disease and injury was developed to meet healthcare, priority setting, and policy planning needs. The first such system, the Global Burden of Disease (GBD), was implemented in 1990. However, problems associated with limited data and assumed disability weightings remain to be resolved. The purpose of the present study was to estimate national burdens of injuries in Korea using more reliable data and disability weightings. The incidences of injuries were estimated using the Korean National Hospital Discharge Survey and the mortality data from the Korean National Statistical Office in 2010. Additionally, durations of injuries and age at injury onset were used to calculate disability-adjusted life years (DALY) using disability weightings derived from the Korean Burden of Disease (KBD) study. Korea had 1,581,072 DALYs resulting from injuries (3,170 per 100,000), which was 22.9% higher than found by the GBD 2010 study. Males had almost twice as heavy an injury burden as females. Road injury, fall, and self-harm ranked 1st, 2nd, and 3rd in terms of burden of injury in 2010. Total injury burden peaked in the forties, while burden per person declined gradually from early adulthood. We hope that this study contributes to the reliable evaluation of injury burden and a better understanding of injury-related health status using nation-specific, dependable data.

Subsequent Injury Study (SInS): Improving outcomes for injured New Zealanders

BACKGROUND

Subsequent injury (SI) is a major contributor to disability and costs for individuals and society.

AIM

To identify modifiable risk factors predictive of SI and SI health and disability outcomes and costs.

OBJECTIVES

To (1) describe the nature of SIs reported to New Zealand's no-fault injury insurer (the Accident Compensation Corporation (ACC)); (2) identify characteristics of people underaccessing ACC for SI; (3) determine factors predicting or protecting against SI; and (4) investigate outcomes for individuals, and costs to society, in relation to SI.

DESIGN

Prospective cohort study.

METHODS

Previously collected data will be linked including data from interviews undertaken as part of the earlier Prospective Outcomes of Injury Study (POIS), ACC electronic data and national hospitalisation data about SI. POIS participants (N=2856, including 566 Māori) were recruited via ACC's injury register following an injury serious enough to warrant compensation entitlements. We will examine SI over the following 24 months for these participants using descriptive and inferential statistics including multivariable generalised linear models and Cox's proportional hazards regression.

DISCUSSION

Subsequent Injury Study (SInS) will deliver information about the risks, protective factors and outcomes related to SI for New Zealanders. As a result of sourcing injury data from New Zealand's 'all injury' insurer ACC, SInS includes people who have been hospitalised and not hospitalised for injury. Consequently, SInS will provide insights that are novel internationally as other studies are usually confined to examining trauma registries, specific injuries or injured workers who are covered by a workplace insurer rather than a 'real-world' injury population.

Retrospectively patient-reported pre-event health status showed strong association and agreement with contemporaneous reports

OBJECTIVE

The unpredictability of the occurrence of illnesses and injuries leading to most emergency admissions to hospital makes it impossible prospectively to collect preadmission patient-reported outcome measures (PROMs). Our aims were to review the evidence for using retrospective PROMs to determine pre-event health status and the validity of using general population norms instead of retrospective PROMs.

STUDY DESIGN AND SETTING

Searches of Medline, PsycINFO, Embase, Global Health, and Health Management information. Six studies met the inclusion criteria for the first aim, and 11 studies addressed the second aim. Narrative syntheses were conducted.

RESULTS

Strong associations were found between retrospective and contemporary PROMs in 21 of 30 comparisons (correlation coefficients over 0.68) and 20 of 24 showed strong agreement for continuous measures (intraclass correlations over 0.75). Categorical measures revealed only fair to moderate levels of agreement (kappa 0.3-0.6). Associations were stronger for indices than for individual items and for shorter time intervals. The direction of differences was inconsistent. Retrospective PROMs reported by elderly patients were similar to the general population but younger adults had been healthier.

CONCLUSION

Retrospective collection offers a means of assessing PROMs in unexpected emergency admissions. However, further research is needed to establish the best policy for their use.

Disability weights based on patient-reported data from a multinational injury cohort

Objective

To create patient-based disability weights for individual injury diagnosis codes and nature-of-injury classifications, for use, as an alternative to panel-based weights, in studies on the burden of disease.

Methods

Self-reported data based on the EQ-5D standardized measure of health status were collected from 29 770 participants in the Injury-VIBES injury cohort study, which covered Australia, the Netherlands, New Zealand, the United Kingdom of Great Britain and Northern Ireland and the United States of America. The data were combined to calculate new disability weights for each common injury classification and for each type of diagnosis covered by the 10th revision of the International statistical classification of diseases and related health problems. Weights were calculated separately for hospital admissions and presentations confined to emergency departments.

Findings

There were 29 770 injury cases with at least one EQ-5D score. The mean age of the participants providing data was 51 years. Most participants were male and almost a third had road traffic injuries. The new disability weights were higher for admitted cases than for cases confined to emergency departments and higher than the corresponding weights used by the Global Burden of Disease 2013 study. Long-term disability was common in most categories of injuries.

Conclusion

Injury is often a chronic disorder and burden of disease estimates should reflect this. Application of the new weights to burden studies would substantially increase estimates of disability-adjusted life-years and provide a more accurate reflection of the impact of injuries on peoples’ lives.

A longitudinal study on quality of life after injury in children

BACKGROUND

In high income countries, injuries account for 40 % of all child deaths, representing the leading cause of child mortality and a major source of morbidity. The need for studies across age groups, and use of health related quality of life measures that assess functional limitations in multiple health domains, with sampling at specific post-injury time points has been identified. The objective of this study was to describe the impact of childhood injury and recovery on health related quality of life (HRQoL) for the 12 months after injury.

METHODS

In this prospective cohort study parents of children 0-16 years old attending British Columbia Children's Hospital for an injury were surveyed over 12 months post-injury. Surveys assessed HRQoL at four points: baseline (pre-injury), one month, four to six months and 12 months post injury. Generalized estimating equation models identified factors associated with changes in HRQoL over time.

RESULTS

A total of 256 baseline surveys were completed. Response rates for follow-ups at one, four and twelve months were 74 % (186), 67 % (169) and 64 % (161), respectively. The mean age of participants was 7.9 years and 30 % were admitted to the hospital. At baseline, a retrospective measure of pre-injury health, the mean HRQoL score was 90.7. Mean HRQoL ratings at one, four and 12 months post injury were 77.8, 90.3 and 91.3, respectively. Both being older and being hospitalized were associated with a steeper slope to recovery.

CONCLUSIONS

Although injuries are prevalent, the long term impacts of most childhood injuries are limited. Regardless of injury severity, most injured children recuperated quickly, and had regained total baseline status by four month post-injury. However, although hospitalization did not appear to impact long term psychosocial recovery, at four and 12 months post injury a greater proportion of hospitalized children continued to have depressed physical HRQoL scores. Both older and hospitalized children reported greater impact to HRQoL at one month post injury, and both had a steeper slope to recovery and were on par with their peers by four month.

Epidemiological Characteristics and Overall Burden of Accidental Injuries in Navarra, Spain: Epidemiology of Injuries in Children

Injuries caused by accidents or violent situations in pediatric patients are a serious social problem where prevention plays a key role. The aim of this study was to describe the epidemiological situation of pediatric injuries in Spain. A prospective study of pediatric patients receiving care in the Emergency Service of the Complejo Hospitalario de Navarra due to for reasons of accidental injury was conducted. The study covered a period of 1 year and assessed a total of 16 variables. There were a total of 8,876 patients, of whom 56.4% were males. Traumatic injuries such as fractures and craniocerebral trauma were identified as the most frequent injuries, occurring as a result of injuries mainly in the home. In females, there was a decrease in the incidence of injuries related to age. There was a greater incidence at the end of the day, during the weekend, and in the months of March to October. The epidemiological profile of pediatric patients who met with accidents in Navarra, Spain, is described. The knowledge of the main areas and factors related to injuries allows us to improve preventive measures, which would contribute to better control in this region of Spain.

Return to Work and Functional Outcomes After Major Trauma: Who Recovers, When, and How Well?

OBJECTIVE

To describe the long-term outcomes of major trauma patients and factors associated with the rate of recovery.

BACKGROUND

As injury-related mortality decreases, there is increased focus on improving the quality of survival and reducing nonfatal injury burden.

METHODS

Adult major trauma survivors to discharge, injured between July 2007 and June 2012 in Victoria, Australia, were followed up at 6, 12, and 24 months after injury to measure function (Glasgow Outcome Scale-Extended) and return to work/study. Random-effects regression models were fitted to identify predictors of outcome and differences in the rate of change in each outcome between patient subgroups.

RESULTS

Among the 8844 survivors, 8128 (92%) were followed up. Also, 23% had achieved a good functional recovery, and 70% had returned to work/study at 24 months. The adjusted odds of reporting better function at 12 months was 27% (adjusted odds ratio 1.27, 95% confidence interval [CI] 1.19-1.36) higher compared with 6 months, and 9% (adjusted odds ratio 1.09, 95% CI, 1.02-1.17) higher at 24 months compared with 12 months. The adjusted relative risk (RR) of returning to work was 14% higher at 12 months compared with 6 months (adjusted RR 1.14, 95% CI, 1.12-1.16) and 8% (adjusted RR 1.08, 95% CI, 1.06-1.10) higher at 24 months compared with 12 months.

CONCLUSIONS

Improvement in outcomes over the study period was observed, although ongoing disability was common at 24 months. Recovery trajectories differed by patient characteristics, providing valuable information for informing prognostication and service planning, and improving our understanding of the burden of nonfatal injury.

Health related quality of life and return to work after minor extremity injuries: A longitudinal study comparing upper versus lower extremity injuries

PURPOSE

To investigate the impact on health related quality of life (HRQL) during the first year after minor extremity injury and to determine whether there is a difference in recovery patterns and return to work between upper extremity injuries (UEI) and lower extremity injuries (LEI).

METHOD

A total of 181 adults' age 18 years or older randomly selected from patients admitted to an emergency department with minor injuries were studied. HRQL was measured using the Functional Status Questionnaire (FSQ) at 1-2 weeks, 3, 6, and 12-months post-injury. Pre-injury FSQ scores were measured retrospectively at admission. A quasi-least square (QLS) model was constructed to examine differences of FSQ scores at each measuring point for UEI and LEI.

RESULTS

Fractures of the knee/lower leg (25%) were the most frequently injured body area. Slips or falls (57%) and traffic-related events (22%) were the most common injury causes. The mean ISS was 4.2 (SD 0.86). Both groups had significant declines in the FSQ scores physical and social functioning at 1-2 weeks after injury. Patients with UEI made larger improvements in the first 3 months post-injury versus patients with LEI whose improvements extended over the first 6 months. None of the groups reached the pre-injury FSQ scores during the first post-injury year except in the subscale work performance where UEI exceeded the pre-injury scores. At 12 months post-injury, significant lower FSQ scores remained in the LEI group compared to the UEI group in intermediate activities of daily living (p=0.036, d 0.4) and work performance (p=0.004, d 0.7). The return to work at 3 months and 12 months were 76% and 88% for UEI and 58% and 77% for LEI. No significant differences were found between groups in the FSQ scale mental health and social interaction.

CONCLUSIONS

LEI had the highest impact on HRQL and return to work during the first year which exceeded the consequences of UEI. These findings contribute to the information about the consequences of injury in order to give sufficient prognostic information to patients and different stakeholders. Future investigations should aim to investigate specific minor extremity injuries and identify factors that facilitate recovery and return to work.

A hospital based surveillance system to assess the burden of trauma in KwaZulu-Natal Province South Africa

INTRODUCTION

In response to the ongoing excessive burden of trauma in South Africa the Data Management and Epidemiology Units of the Department of Health in conjunction with a group of trauma specialists developed a number of trauma data variables for inclusion on the routine District Health Information System (DHIS). The aim of this study is to describe the process followed and review the 2012-2014 data.

METHODOLOGY

The variables collected included: total patient numbers assessed in the emergency room with a diagnosis of trauma; the mechanisms of trauma (blunt assault, motor vehicle accident, pedestrian vehicle accident, stab, gunshot wound, other); any trauma patient admitted to a health facility ward/ICU for longer than 12h; and whether the patient required transfer to a higher centre of care. All trauma deaths in hospital were recorded. The severity of trauma was measured using the Emergency Medical Services (EMS) classification of blue code (dead), red code (stretcher case with deranged physiology), yellow code (stretcher case with normal physiology) and green code (able to walk with normal physiology. The DHIS trauma data from April 2012 to March 2014 was reviewed.

RESULTS

There were 197,219 emergency room visits for trauma in KZN in the 2013/2014 financial year. This constitutes 27.0% of all emergency room visits. The ratio of intentional to non-intentional injury is 45:55. There were 18,716 admissions to public sector hospitals for trauma in KZN in the 2013/2014 financial year. This constitutes 2.4% of all admissions in the province. There were 1045 inpatient deaths due to trauma in the same period, constituting 2.5% of all inpatient deaths. The overall rate of trauma in KZN was 17 per 1000 population.

CONCLUSION

The adapted DHIS has successfully collected essential data that quantify the hospital burden of trauma in KZN province. This has provided the most complete overview of the burden of trauma in the Province. These trauma indicators should remain a permanent part of the DHIS to allow planners to track the trauma epidemic and to institute informed management strategies.

An evaluation of the impact of 'Lifeskills' training on road safety, substance use and hospital attendance in adolescence

PURPOSE

To evaluate if attendance at Lifeskills, a safety education centre for children in Year 6 (10-11 years), is associated with engagement in safer behaviours, and with fewer accidents and injuries, in adolescence.

METHODS

The sample are participants in the Avon Longitudinal Study of Parents and Children who attended school in the Lifeskills catchment area in Year 6; 60% attended Lifeskills. At 14-15 years, participants (n approximately 3000, varies by outcome) self-reported road safety behaviours and accidents, and perceived health effects and use of alcohol, cannabis, and tobacco. Additional outcomes from linkage to Hospital Episodes Statistics were available for a sub-sample (n=1768): hospital admittance (for accident-related reason, from 11-16 years) and A&E attendance (for any reason, from approximately 14-16 years).

RESULTS

Children who attended Lifeskills were more likely to report using pedestrian crossings on their way to school than children who did not attend (59% versus 52%). Lifeskills attendance was unrelated to the ownership of cycle helmets, or the use of cycle helmets, seat belts, or reflective/fluorescent clothing, or to A&E attendance. Use of cycle helmets (37%) and reflective/fluorescent clothing (<4%) on last cycle was low irrespective of Lifeskills attendance. Lifeskills attendance was associated with less reported smoking and cannabis use, but was generally unrelated to perceptions of the health impact of substance use.

CONCLUSIONS

Lifeskills attendance was associated with some safer behaviours in adolescence. The overall low use of cycle helmets and reflective/fluorescent clothing evidences the need for powerful promotion of some safer behaviours at Lifeskills and at follow-up in schools.

A evolução da carga de causas externas no Brasil: uma comparação entre os anos de 1998 e 2008

Resumo O objetivo foi comparar as estimativas das causas externas provenientes do estudo Carga Global de Doenças, entre os anos 1998 e 2008. A estimação do DALY (disability-adjusted life year) e do YLL (years of life lost) foi baseada em metodologia do estudo Carga Global de Doenças. Para o cálculo do YLD (years lived with disability), foram incluídas informações sobre atendimentos em emergências. Para comparabilidade, fez-se necessária a aplicação da mesma metodologia nos dois momentos analisados, tendo sido a mais recente eleita como padrão de referência. Em ambos os anos as causas externas foram responsáveis por cerca de 10% do total do DALY. Entretanto, sua distribuição interna apresentou marcada diferença entre as regiões do Brasil, com queda no Sudeste e aumento no Norte e Nordeste. Houve aumento das causas intencionais e o DALY se tornou mais letal (maior parcela de YLL). Espera-se que tais resultados balizem a formulação de políticas e/ou o aprimoramento das já existentes com vistas ao efetivo enfrentamento das causas externas.
