The association between motor vehicle injuries and health-related quality of life: a longitudinal study of a population-based sample in the United States

Twelve-month recovery following road trauma: Results from an inception cohort in Vancouver, Canada

BACKGROUND

Injury-related disability following road trauma is a major public health concern. Unfortunately, outcome following road trauma and risk factors for poor recovery are inadequately studied, especially for road trauma survivors with minor injuries that do not require hospitalization.

OBJECTIVES

This manuscript reports 12-month recovery outcomes for a large cohort of road trauma survivors.

METHODS

This was a prospective, observational inception cohort study of 1,480 road trauma survivors recruited between July 2018 and March 2020 from 3 trauma centres in British Columbia, Canada. Participants were aged ≥16 years and arrived in a participating emergency department within 24 h of a motor vehicle collision. Data on baseline health and injury severity were collected from structured interviews and medical records. Outcome measures, including the SF-12, were collected during follow-up interviews at 2, 4, 6 and 12 months. Predictors of recovery outcomes were identified using Cox proportional hazards models and summarized using hazard ratios.

RESULTS

Only 42 % of participants self-reported full recovery and only 66 % reported a return to usual daily activities. Females, older individuals, pedestrians, and those who required hospital admission had a poorer recovery than other groups. Similar patterns were observed for the SF-12 physical component. For the SF-12 mental component, no significant differences were observed between participants admitted to hospital and those discharged home from the ED. Return to work was reported by 77 % of participants who had a paying job at baseline, with no significant differences between sex and age groups.

CONCLUSIONS

In a large cohort of road trauma survivors, under half self-reported full recovery one year after the injury. Poor mental health recovery was observed in both participants admitted to hospital and those discharged home from the ED. This finding may indicate a need for early intervention and continued mental health monitoring for all injured individuals, including for those with less serious injuries.

Subjective and Objective Improvement in a 39-Year-Old Male Suffering From Severe Chronic Pain and Disability Using Chiropractic BioPhysics® Protocols Following Rear-Impact Motor Vehicle Crash With a 10-Month Long-Term Follow-Up

We present the case of a patient receiving structural rehabilitation following a rear-impact motor vehicle collision (MVC). Medications did not alleviate the symptoms of the crash injuries. Resolution of injury-caused pain and disability was found following postural and structural rehabilitation treatment. A 39-year-old male was injured in a rear-impact collision between two very large vehicles. Severe migraine headaches, neck pain, and radiculopathy, as well as lower back pain, were the result of the crash. Patient-reported outcomes (PROs) demonstrated that the symptoms were causing severe disability and poor health-related quality of life (HRQoL) measures. Radiographs found spine alignment abnormalities consistent with rear impact MVC. Chiropractic Biophysics® (CBP®) structural rehabilitation was performed. Following a treatment regimen involving strengthening weakened and damaged muscles, postural and spinal traction, postural spinal manipulative therapy (SMT), and home therapies resulted in the resolution of the symptoms. All outcome measures demonstrated improvement, including Short-Form 36 question health questionnaire (SF-36), quadruple visual analog scale (QVAS), headache disability index (HDI), neck disability index (NDI), revised Oswestry disability index (RODI), as well as significant measured improvements found on radiographs. Spine pain and altered alignment are frequent results of MVCs. If left uncorrected, these abnormalities increase the likelihood of chronic pain and disability. Combined low back pain (LBP), neck pain (NP), headache (HA), and radiculopathy, as found in our subject, significantly pre-dispose the individual to poor HRQoL, years lived with disability (YLDs) and increased the global burden of disease (GBD). Physicians who treat injured patients should have a repeatable, reliable, valid, and efficacious method to reduce pain, increase range of motion (ROM), improve spine alignment, and improve the performance of activities of daily living (ADLs). Further, larger studies of injured patients are necessary to determine if the CBP® protocol reduces GBD caused by MVC injuries.

Demographic and clinical profile of an inception cohort of road trauma survivors

BACKGROUND

Road trauma is a major public health concern, often resulting in reduced health-related quality of life and prolonged absenteeism from work even after so-called 'minor' injuries that do not result in hospitalization. This manuscript compares pre-injury health, sociodemographic characteristics and injury details between age, sex, and road user categories in a cohort of 1,480 road trauma survivors.

METHODS

This was a prospective observational inception cohort study of road trauma survivors recruited between July 2018 and March 2020 from three trauma centres in British Columbia, Canada. Participants were aged ≥ 16 years and arrived in a participating emergency department within 24 h of involvement in a motor vehicle collision. Data were collected from structured interviews and review of medical records.

RESULTS

The cohort of 1,480 road trauma survivors included 280 pedestrians, 174 cyclists, 118 motorcyclists, 683 motor vehicle drivers, and 225 passengers. Median age was 40 (IQR = [27, 57]) years; 680 (46%) were female. Males and younger patients were significantly more likely to report better pre-injury physical health. Motorcyclists and cyclists tended to report better physical health and less severe somatic symptoms, whereas pedestrians and motor vehicle drivers reported better mental health. Injury severity and hospital admission rates were higher in pedestrians and motorcyclists and lower in motorists. Upper and lower extremity injuries were most common in pedestrians, cyclists and motorcyclists, whereas neck injuries were most common in motor vehicle drivers and passengers.

CONCLUSIONS

In a large cohort of road trauma survivors, overall injury severity was low. Motorcyclists and pedestrians, but not cyclists, had more severe injuries than motorists. Extremity injuries were more common in vulnerable road users. Future research will investigate one-year recovery outcomes and identify risk factors for poor recovery.

Opportunities to Improve Palliative Care Delivery in Trauma Critical Illness

BACKGROUND

Despite recommendations to integrate palliative care (PC) into care for critically ill trauma patients, little is known about current PC practices in trauma care to inform opportunities for improvement.

OBJECTIVE

Describe patterns of PC delivery among a large, critically ill trauma cohort.

SETTING/SUBJECTS

Retrospective cohort study of adult (≥18 years) trauma patients admitted to an intensive care unit (ICU) at an urban, level one trauma center in the United States from March 1, 2017 to March 1, 2019.

METHODS

We linked the electronic medical record with the institutional trauma registry. PC process measures included a PC consult order, advance care planning (ACP) note, and hospice use. Unadjusted results are reported for the total population, decedents, and subgroups at risk for poor outcomes (age ≥55 years, Black race ≥1 pre-existing comorbidity, and severe injury) after trauma.

RESULTS

Among 1309 eligible admissions, 902 (68.9%) were male, 640 (48.9%) were Black, and 654 (50.0%) were ≥55 years old. Eighty-one (6.2%) patients received a PC consult order, 66 (5.0%) had an ACP note, and 13 (1.1%) were discharged to hospice. Among decedents (N = 91; 7%), 28 (30.8%) received a PC consult order and 36 (39.6%) had an ACP note. For high-risk subgroups, PC consult orders and ACP note rates ranged from 4.5-12.8% and 4.5-11.8%, respectively.

CONCLUSION

PC delivery was rare among this cohort, including those at high risk for poor outcomes. Urgent efforts are needed to identify barriers to and develop targeted interventions for high quality PC delivery in trauma ICU care.

Top Ten Tips Palliative Care Clinicians Should Know About Trauma and Emergency Surgery

There is growing interest in, and need for, integrating palliative care (PC) into the care of patients undergoing emergency surgery and those with traumatic injury. Thus, PC consults for these populations will likely grow in the coming years. Understanding the nuances and unique characteristics of these two acutely ill populations will improve the care that PC clinicians can provide. Using a modified Delphi technique, this article offers 10 tips that experts in the field, based on their broad clinical experience, believe PC clinicians should know about the care of trauma and emergency surgery patients.

Trajectory of self-rated health after combat-related injury

BACKGROUND

The U.S. military conflicts in Iraq and Afghanistan yielded the most combat casualties since Vietnam. With more service members than ever surviving their wounds, prospective research on factors related to long-term, patient-reported outcomes, including self-rated health (SRH), has increased importance. This study's objective was to use preinjury and postinjury SRH measures to identify trajectories and predictors of SRH after combat-related injury.

METHODS

The Wounded Warrior Recovery Project was queried for U.S. military personnel with combat-related injuries from Iraq or Afghanistan between 2004 and 2011. A single-item measure was used to assess SRH once prior to injury and twice after injury, and responses included excellent, very good, good, fair, or poor. Only those with good or better preinjury SRH levels were included. SRH trajectories were identified and defined. Multinomial logistic regression examined the association between injury-specific characteristics, post-traumatic stress disorder (PTSD), and SRH trajectory.

RESULTS

The study sample included 1,093 military personnel. Overall, 4 SRH trajectories were identified: (1) 56.7% resilient (preinjury SRH level was maintained throughout follow-up), (2) 9.4% recovered (SRH declined on first postinjury measure then returned to preinjury level), (3) 22.9% delayed (SRH declined only on second postinjury measure), and (4) 11.0% chronic (SRH declined on first postinjury measure and did not return to preinjury level). In multinomial logistic regression and relative to the resilient group, screening PTSD positive, serious-severe injury severity, and lower extremity injury predicted membership in the recovered and chronic groups, whereas back injury predicted membership in the chronic group only.

CONCLUSION

This is the first study to examine long-term SRH trajectory following combat-related injury, finding that a majority of military personnel remain at their preinjury health levels of good or better. Decreases in postinjury SRH were associated with physical and psychological factors, which reinforces the need for a multidisciplinary approach to care.

Health-Related Quality of Life in Motorcycle Crash Victims One Year After Injury: A Longitudinal Study in Ho Chi Minh City, Vietnam

Despite the burden of injury associated with motorcycle crashes and injuries in Vietnam, there are no studies investigating health-related quality of life (HRQoL) following a nonfatal motorcycle crash in this country. Therefore, this study aimed to evaluate the change of HRQoL preinjury, and at 6 and 12 months postinjury motorcycle crash in Ho Chi Minh City, Vietnam. Outcome measures were Physical Component Scores (PCS) and Mental Component Scores (MCS) of the Short Form 12 Health Survey (SF-12) version 2 and the EQ-5D. Multilevel mixed models were undertaken. A total of 352 hospitalized motorcyclists were followed-up. Compared with preinjury, the SF-12 PCS reduced by 6.61 points (95% confidence interval [CI] = -8.21 to -5.03) and 5.12 points (95% CI = -6.74 to -3.51) at 12 months postinjury. MCS also reduced by 4.23 points (95% CI = -5.99 to -2.47) at 6 months but increased by 1.29 points (95% CI = -0.49 to 3.08) at 12 months postinjury. The EQ-5D Visual Analogue Scale score decreased by 10.41 points (95% CI = -11.49 to -9.33) at 6 months and 6.48 points (95% CI = -7.58 to -5.38) at 12 months postinjury. The HRQoL among injured motorcycle riders improved between 6 and 12 months after injury but had not returned to the levels before injury.

Quality of life in the limelight: a study protocol of a Swedish register-based cohort study on quality of life after an injury

INTRODUCTION

Currently, there are very few published studies on preinjury and postinjury assessments of quality of life (QoL) based on a prospective appraisal; specifically, knowledge of those who do not seek medical care following injury is lacking. To close these knowledge gaps, this study aims to identify the psychosocial consequences in terms of loss of QoL following injury in a Swedish population and to investigate the response shift in retrospective measures of self-reported QoL.

METHODS AND ANALYSIS

We will analyse preinjury and postinjury (including both minor and severe unintentional injuries as well as different injury mechanisms) assessments of QoL, including the phenomenon of response shift, using register-based data from the nationwide collaboration project LifeGene, which includes over 52 000 individuals living in Sweden. In addition to LifeGene data, a short online survey including a 'ThenTest' questionnaire, that is, comparison of previous QoL to current using EuroQoL five-dimensional questionnaire, was sent out to the participants of LifeGene. This study will provide a unique opportunity to study the changes in QoL by comparing preinjury and postinjury assessments using a prospective appraisal, both for populations who have sought medical care as well as those who have not due to their injury. Similarly, the study will also assess the response shift in retrospective measures of QoL. This information can guide the next generation of QoL measures and interventions for those suffering injuries and have an impact on how to interpret evaluations of interventions.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the Regional Ethical Review Board in Stockholm, Sweden (case number 2018/352-31). The results will be disseminated through peer-reviewed journals, conference presentations, print media and internet and via a report for the funding agency.

Agreement between retrospectively assessed health-related quality of life collected 1 week and 12 months post-injury: an observational follow-up study

Background

Retrospective assessment of pre-injury health-related quality of life (HRQL) is frequently used to measure change from pre- to post-injury HRQL. However, retrospective measurement may be confounded by recall bias. It is assumed that presence of recall bias is influenced by several factors, such as the measurement scale or the instrument that is used, the measurement schedule, and the presence of a substantial health event during the follow up period. This study empirically tests these assumptions by comparing pre-injury EQ-5D summary scores, EQ-5D profiles and visual analogue scale (EQ-VAS) scores of trauma patients, as recorded 1 week and 12 months post-injury, respectively.

Methods

A sample of 5371 adult trauma patients who attended the Emergency Department (ED) followed by hospital admission, received postal questionnaires 1 week (T1) and 12 months (T2) post-injury. The questionnaires contained items on pre-injury health, in terms of EQ-5D3L and EQ-VAS.

Results

One thousand one hundred sixty-six completed data pairs with T1 and T2 pre-injury data were available. Mean pre-injury EQ-5D summary scores were 0.906 (T1) and 0.905 (T2), respectively, with moderate intertemporal agreement (intraclass correlation coefficient (ICC) T1T2 = 0.595). In absolute terms, 442 (37.9%) respondents reported a different pre-injury EQ-5D profile at T2 compared to T1. The least stable EQ-5D dimension was pain/discomfort (20.2% reported a change). Mean T2 pre-injury EQ-VAS score was significantly higher than mean T1 pre-injury EQ-VAS score (T2 84.6 versus T1 83.3). Multivariable logistic regression analysis indicated that lower educational level, comorbid disease and having PTSD symptoms were independent predictors of change of pre-injury EQ-5D profile.

Conclusions

Despite one third of respondents reported a different pre-injury health level, if asked for on two interview occasions separated by 1 year, on the group level this difference was nil (EQ-5D summary score) to small (EQ-VAS). The consistent symmetrical pattern of change suggests random error to play the largest role. Intertemporal reliability was the same in EQ-5D profiles vs. EQ-VAS scores, ruling out scale effects. Particularly certain trauma subgroups showed highest distortion. While group comparisons may be trusted, in pre-post analysis and repeated measure analysis the individual injury impact and recovery pattern may be wrongly estimated.

Biomarkers of autonomic regulation for predicting psychological distress and functional recovery following road traffic injuries: protocol for a prospective cohort study

INTRODUCTION

Psychological distress is a prevalent condition often overlooked following a motor vehicle crash (MVC), particularly when injuries are not severe. The aim of this study is to examine whether biomarkers of autonomic regulation alone or in combination with other factors assessed shortly after MVC could predict risk of elevated psychological distress and poor functional recovery in the long term, and clarify links between mental and physical health consequences of traffic injury.

METHODS AND ANALYSIS

This is a controlled longitudinal cohort study, with follow-up occurring at 3, 6 and 12 months. Participants include up to 120 mild to moderately injured MVC survivors who consecutively present to the emergency departments of two hospitals in Sydney and who agree to participate, and a group of up to 120 non-MVC controls, recruited with matched demographic characteristics, for comparison. WHO International Classification of Functioning is used as the framework for study assessment. The primary outcomes are the development of psychological distress (depressive mood and anxiety, post-traumatic stress symptoms, driving phobia, adjustment disorder) and biomarkers of autonomic regulation. Secondary outcomes include indicators of physical health (presence of pain/fatigue, physical functioning) and functional recovery (quality of life, return to function, participation) as well as measures of emotional and cognitive functioning. For each outcome, risk will be described by the frequency of occurrence over the 12 months, and pathways determined via latent class mixture growth modelling. Regression models will be used to identify best predictors/biomarkers and to study associations between mental and physical health.

ETHICS AND DISSEMINATION

Ethical approvals were obtained from the Sydney Local Health District and the research sites Ethics Committees. Study findings will be disseminated to health professionals, related policy makers and the community through peer-reviewed journals, conference presentations and health forums.

Measuring and assessing risk of quality of life loss following a road traffic injury: A proposed methodology for use of a composite score

INTRODUCTION

Assessments of the impact of road traffic injuries (RTIs) on quality of life (QoL) can benefit from the use of combined characteristics of the injurious event.

AIM

The burden of having sustained a RTI was computed using a composite score that comprised three elements (i.e. number of injuries sustained in the crash, body parts affected, and severity of the injuries) that relate to the probability of subsequent long-term QoL lost by individuals 1-4 years after the crash.

METHODOLOGY

The QoL of injured victims aged 11-90 years that crashed in Sweden between 2007 and 2009 was compared with that of a random sample of non-injured individuals frequency-matched by sex and age. Injury information to build the composite score was obtained from a national register that contains data on the number of injuries, their severity, and the body parts affected. The QoL was assessed in 2010 for both injured and non-injured individuals using the standardized Euro Quality of Life questionnaire. Logistic regression was used to investigate whether the composite score was predictive of low QoL (<90% of the mean of non-injured referents) adjusting for sex, age, and time elapsed since the injury occurrence. The composite score was grouped into five exposure categories (0.01-1, 1.01-1.5, 1.51-2, 2.01-3 and 3.01-9 units).

RESULTS

Compared with the non-injured reference group, all exposure categories showed statistically significant increased adjusted ORs for low QoL ranging from 2.35 (95% CI 1.48-3.72) in the 0.01-1.00 lowest injury category to 6.10 (95% CI 3.65-10.2) in the highest 3.01-9.00 with a slightly decreasing plateau in the intermediate categories (point ORs between 3.86 and 3.06). Yet, all 95% CIs across the exposure categories overlapped.

CONCLUSION

Long-term reduction in QoL is a burden experienced by the victims of mild to severe RTCs. The proposed composite score can be an initial step in the development of more elaborated instruments that can be useful in policy making and regulation.

Quality of life following road traffic injury: A systematic literature review

PURPOSE

To assess and provide a systematic overview of current knowledge about the relationship between quality of life (QoL) and road traffic injury, and to appraise how QoL is affected by road traffic injury.

METHODS

A systematic review of the literature published since 1990 on QoL after a road traffic injury, including adult and paediatric populations, from three databases (Pubmed, PsychInfo and SafetyLit) was undertaken. The methodological quality was assessed according to the Newcastle-Ottawa Quality Assessment Scale.

RESULTS

Thirty articles were included and assessed for quality. The QoL scores of those injured were similar to population norms at the first assessment, followed by a drop at the second assessment. An increase of QoL from the second to third assessment was reported, but participants never reached the population norms at the last follow-up (range six weeks to two years), with an exception of those claiming compensation and those with lower extremity fractures. Age, gender, socioeconomic status, injury severity, injury type and post-traumatic stress disorder were associated with reduced QoL.

CONCLUSIONS

Available literature regarding QoL among injured in road traffic crashes is heterogeneous with regard to aims and tools used for assessment. Our review confirmed that independent of measure, the overall QoL was significantly reduced after a road traffic injury compared to the general population norms. Persons who are older, of female gender, lower socioeconomic status, diagnosed with post-traumatic stress disorder, with more severe injuries or injuries to the lower limbs are more vulnerable to loss of QoL following road traffic injury compared to other patient groups injured in road traffic crashes.

Recovery trajectories for long-term health-related quality of life following a road traffic crash injury: Results from the UQ SuPPORT study

BACKGROUND

Diminished physical and mental health-related quality of life (HRQoL) is a common consequence of road traffic crash (RTC) injury. This study aimed to (a) determine the probable recovery trajectories in physical and mental HRQoL; (b) examine the impact of posttraumatic stress disorder (PTSD) on HRQoL scores within these trajectory groups; and (c) examine the influence of predictor covariates on trajectory group membership.

METHODS

336 (63% female, M_age =44.72; SD =14.77) injured RTC survivors completed the SF-36v2 at approximately 6, 12, and 24 months after sustaining a RTC injury. Participants also completed telephone interviews to assess prior history of psychological disorder and current PTSD at each wave.

RESULTS

Three trajectories were identified for SF-36v2 Physical Component Score (PCS): "gradual recovery" (27.3%);"low but improving" (54.7%); and"severe and chronic" (17.9%). Four trajectories were defined for SF36v2 Mental Component Score (MCS): "unaffected" (19.1%);"severe but improving" (24.1%);"severe and declining" (17.3%); and"low but improving" (39.5%). A PTSD diagnosis significantly reduced SF36v2 component scores only in trajectories associated with poorer outcome. Age was predictive of trajectory group membership for PCS, whereas injury severity was predictive of trajectory group membership for MCS.

LIMITATIONS

Use of a compensation seeking sample affects generalizability to the general RTC population.

CONCLUSIONS

This study identified a concerning subgroup of individuals who have chronic and/or declining physical and mental HRQoL that can be impacted by a diagnosis of PTSD. The development of interventions with a special focus on associated psychological injury is needed to improve the HRQoL of at-risk individuals following RTC injury.

Assessment of pre-injury health-related quality of life: a systematic review

Background

Insight into the change from pre- to post-injury health-related quality of life (HRQL) of trauma patients is important to derive estimates of the impact of injury on HRQL. Prospectively collected pre-injury HRQL data are, however, often not available due to the difficulty to collect these data before the injury. We performed a systematic review on the current methods used to assess pre-injury health status and to estimate the change from pre- to post-injury HRQL due to an injury.

Methods

A systematic literature search was conducted in EMBASE, MEDLINE, and other databases. We identified studies that reported on the pre-injury HRQL of trauma patients. Articles were collated by type of injury and HRQL instrument used. Reported pre-injury HRQL scores were compared with general age- and gender-adjusted norms for the EQ-5D, SF-36, and SF-12.

Results

We retrieved results from 31 eligible studies, described in 41 publications. All but two studies used retrospective assessment and asked patients to recall their pre-injury HRQL, showing widely varying timings of assessments (soon after injury up to years after injury). These studies commonly applied the SF-36 (n = 13), EQ-5D (n = 9), or SF-12 (n = 3) using questionnaires (n = 14) or face-to-face interviews (n = 11). Two studies reported prospective pre-injury assessment, based on prospective longitudinal cohort studies from a sample of initially non-injured patients, and applied questionnaires using the SF-36 or SF-12. The recalled pre-injury HRQL scores of injury patients consistently exceeded age- and sex-adjusted population norms, except in a limited number of studies on injury types of higher severity (e.g., traumatic brain injury and hip fractures). All studies reported reduced post-injury HRQL compared to pre-injury HRQL. Both prospective studies reported that patients had recovered to their pre-injury levels of physical and mental health, while in all but one retrospective study patients did not regain the reported pre-injury levels of HRQL, even years after injury.

Conclusions

So far, primarily retrospective research has been conducted to assess pre-injury HRQL. This research shows consistently higher pre-injury HRQL scores than population norms and a recovery that lags behind that of prospective assessments, implying a systematic overestimation of the change in HRQL from pre- to post-injury due to an injury. More prospective research is necessary to examine the effect of recall bias and response shift. Researchers should be aware of the bias that may arise when pre-injury HRQL is assessed retrospectively or when population norms are applied, and should use prospectively derived HRQL scores wherever possible to estimate the impact of injury on HRQL.

Work-Related Injuries and Health-Related Quality of Life Among US Workers: A Longitudinal Study of a Population-Based Sample

OBJECTIVE

The aim of this study is to examine health-related quality of life (HRQOL) among U.S. injured workers using a longitudinal study of a nationally representative sample.

METHODS

Employed adults with and without occupational injuries from the 2000 to 2011 Medical Expenditure Panel Survey (MEPS) were included. Outcomes were the physical and mental components of the SF-12. A within-person change using paired tests and a between-person change using multivariable regression were performed.

RESULTS

We estimate over 1.6 million injured workers per year. Sprains were the most common injury. Relative to noninjured workers, injured workers reported 3.0 and 1.0 points lower physical and mental component scores, respectively.

CONCLUSIONS

These results confirm that occupational injuries cause significant deficits in the physical component of HRQOL. This highlights the importance of preventing occupational injuries to reduce associated disabilities in the U.S.

Longitudinal assessment of injury recidivism among adults in the United States: findings from a population-based sample

Background

Repeated injuries, as known as injury recidivism, pose a significant burden on population health and healthcare settings. Therefore, identifying those at risk of recidivism can highlight targeted populations for primary prevention in order to improve health and reduce healthcare expenditures. There has been limited research on factors associated with recidivism in the U.S. Using a population-based sample, we aim to: 1) identify the prevalence and risk factors for injury recidivism among non-institutionalized adults; 2) investigate the trend in nationwide recidivism rates over time.

Methods

Using the Medical Expenditure Panel Survey (MEPS), 19,134 adults with at least one reported injury were followed for about 2 years. Reported injuries were those associated with healthcare utilization, disability days or any effects on self-reported health. The independent associations between risk factors for recidivism were evaluated incorporating a weighted logistic regression model.

Results

There were 4,136 recidivists representing over nine million individuals in the U.S. over a 2-year follow-up. About 44 % of recidivists sustained severe injuries requiring a hospitalization, a physician’s office visit or an emergency department visit. Compared with those who sustained a single injury, recidivists were more likely to be white, unmarried, reside in metropolitan areas, and report a higher prevalence of chronic conditions. Age, sex, race/ethnicity, marital status, urbanicity, region, diabetes, stroke, asthma and depression symptoms were significant predictors of recidivism. Significant interaction effects between age and gender suggested those in the 18–25 age group, the odds of being a recidivist were 1.45 higher among males than females adjusting for other covariates. While having positive screens for depression in both follow-up years was associated with 1.46 (95 % CI = 1.21–1.77) higher odds of recidivisms than the reference group adjusting for other variables.

Conclusions

We observed a higher recidivism rate among injured individuals in this study than previously reported. Our findings emphasize the pressing need for injury prevention to reduce the burden of repeated injuries. Preventative efforts may benefit from focusing on males between 18 and 25 years of age and those with comorbidities such as diabetes, stroke and depression.

Long-term outcomes of individuals injured in motor vehicle crashes: A population-based study

BACKGROUND

Despite decline in U.S. traffic fatalities, non-fatal injuries remain a main cause of reduced self-reported health. The authors used a nationally representative survey to examine the long-term (≥1 year) implications of traffic injuries on self-care, depression, mobility, pain and activity domains of a widely used measure assessing Health-Related Quality of Life (HRQOL).

METHODS

30,576 participants from panels (2000-2002) of the Medical Expenditure Panel Survey (MEPS) were followed for about two years. The associations between reporting a traffic injury in the first follow-up year and the five domains of the Euroqol Health index (EQ-5D) were assessed using mixed logistic models with outcome severe/moderate problem in each domain. Models adjustment variables included age, gender, education, income, diabetes, asthma, smoking and insurance status.

RESULTS

590 participants reported traffic injuries. In the first follow-up analysis, having an injury was associated with deficits in all domains of the EQ-5D. With the exception of self-care, similar findings were reported in the second follow-up (≥1 year) after injuries with strongest associations between traffic injuries and both mobility and activity (both OR=2.9, P<0.01).

CONCLUSIONS

Traffic injuries are significantly associated with long-term reduced HRQOL. Injured individuals may benefit from early intervention programs to prevent the development of secondary complications and reduced HRQOL.

Frequent falling and motor vehicle collision involvement of older drivers

OBJECTIVES

To examine the relationship between frequent falls in older drivers and motor vehicle collision (MVC) involvement.

DESIGN

Cross-sectional.

SETTING

North central Alabama.

PARTICIPANTS

Population-based sample of 2,000 licensed drivers aged 70 and older.

MEASUREMENTS

Self-reported history of falling two or more times in the prior year was the main predictor. Outcomes were any MVC or at-fault MVC in the prior year.

RESULTS

Approximately 9% of older drivers reported having fallen two or more times in the prior year. Logistic regression models indicated that frequent falling was associated with having any MVC (crude odds ratio (OR) = 1.53, 95% confidence interval (CI) = 0.77-3.02) and an at-fault MVC (OR = 2.21, 95% CI = 0.97-5.06). Adjustment for the potentially confounding effects of demographic, health, visual, and driving characteristics did not meaningfully affect the association with any MVC, whereas the association with at-fault MVC was weakened (adjusted OR = 2.03, 95% CI = 0.84-4.90).

CONCLUSION

Frequent falling was associated with at-fault MVC involvement of older drivers, especially whites. History of falling can be used to identify individuals at risk of MVC involvement and to begin a dialogue about driver safety.
