Association of Health Care Use and Economic Outcomes After Injury in Cameroon

Despite the highest injury rates worldwide, formal medical care is not often sought after injuries in Sub-Saharan Africa. Unaffordable costs associated with trauma care might inhibit injured patients from seeking care. To (1) determine the injury epidemiology in Cameroon using population-representative data, (2) identify the barriers to use of formal health care after injury, and (3) determine the association between use of care and economic outcomes after injury. This mixed-methods, cross-sectional study included a population-representative, community-based survey and nested qualitative semistructured interviews in the urban-rural Southwest Region of Cameroon. Three-stage cluster sampling was used to select target households. Data were collected from January 3 to March 14, 2017, and analyzed from March 3, 2017, to March 3, 2019. Injuries occurring in the preceding 12 months. Postinjury use of health care services, disability, and economic outcomes. All survey data were adjusted for cluster sampling. Of 1551 total households approached, 1287 (83.0%) were surveyed for a total sample size of 8065 participants. The 8065 individuals surveyed included 4181 women (52.0%), with a mean age of 23.9 (standard error [SE], 0.2) years. A total of 503 injuries were identified among 471 unique participants, including 494 nonfatal injuries. Among these, 165 (34.6%) did not seek formal medical services. Disability occurred after 345 injuries (68.6%) and resulted in 11 941 lost days of work in the sample. Family economic hardship after injury was substantially increased among the injured cohort who used formal medical care. Injuries brought to formal medical care, compared with those that were note, incurred higher mean treatment costs ($101.08 [SE, $236.23] vs $12.13 [SE, $36.78]; P < .001), resulted in higher rates of lost employment (19.9% [SE, 3.6%] vs 5.6% [SE, 1.6%]; P = .004), and more frequently led affected families to use economic coping strategies, such as borrowing money (26.2% [SE, 2.7%] vs 7.1% [SE, 1.2%]; P < .001). After adjusting for age and severity, use of formal medical care in Cameroon was independently associated with severe economic hardship after injury, defined as a new inability to afford food or rent (adjusted odds ratio, 1.67; 95% CI, 1.05-2.65). In this study, injury in Southwestern Cameroon was associated with significant disability and lost productivity. Formal medical treatment of injury was associated with significant financial consequences for households of injured patients. Primary prevention of road traffic injuries and financial restructuring of emergency care could improve trauma care access in Cameroon and reduce the societal effects of injury.

Recent Advances in Prevention of Primary and Secondary Anterior Cruciate Ligament Injury: What Does the Future Hold for Optimizing Knee-Joint Function?

Despite considerable advances in anterior cruciate ligament (ACL) injury-risk identification and prevention over the past 20 years, the annual incidence of ACL injury has continued to rise, and females remain at greater risk of both primary and secondary ACL injury. Important questions remain regarding ancillary risk factors we should target, the most effective training and rehabilitation approaches to ensure retention and transfer of learned skills from the rehabilitation setting to real-world sporting environment, and the development of more evidence-based criteria for return to sport that consider the whole athlete. As we look to the future, the optimization of primary and secondary ACL-injury prevention represents a complex, multidisciplinary problem with many unique and exciting opportunities to engage the various subdisciplines of kinesiology to address these emerging questions.

Development and validation of an algorithm to assess risk of first-time falling among home care clients

BackgroundThe falls literature focuses on individuals with previous falls, so little is known about individuals who have not experienced a fall in the past. Predicting falls in those without a prior event is critical for primary prevention of injuries. Identifying and intervening before the first fall may be an effective strategy for reducing the high personal and economic costs of falls among older adults. The purpose of this study was to derive and validate a prediction algorithm for first-time falls (1stFall) among home care clients who had not fallen in the past 90 days.MethodsDecision tree analysis was used to develop a prediction algorithm for the occurrence of a first fall from a cohort of home care clients who had not fallen in the last 90 days, and who were prospectively followed over 6 months. Ontario home care clients who were assessed with the Resident Assessment Instrument-Home Care (RAI-HC) between 2002 and 2014 (n = 88,690) were included in the analysis. The dependent variable was falls in the past 90 days in follow-up assessments. The independent variables were taken from the RAI-HC. The validity of the 1stFall algorithm was tested among home care clients in 4 Canadian provinces: Ontario (n = 38,013), Manitoba (n = 2738), Alberta (n = 1226) and British Columbia (n = 9566).ResultsThe 1stFall algorithm includes the utilization of assistive devices, unsteady gait, age, cognition, pain and incontinence to identify 6 categories from low to high risk. In the validation samples, fall rates and odds ratios increased with risk levels in the algorithm in all provinces examined.ConclusionsThe 1stFall algorithm predicts future falls in persons who had not fallen in the past 90 days. Six distinct risk categories demonstrated predictive validity in 4 independent samples.

Teprenone for the prevention of low-dose aspirin-induced gastric mucosal injury in Helicobacter pylori-negative patients

Objectives: Low-dose aspirin is the standard treatment for the prevention of cardiovascular events in at-risk patients. We performed a randomized, placebo-controlled study to determine the efficacy of teprenone for primary prevention of gastrointestinal injury in patients taking LDA for vascular protection.Methods: Patients were eligible for enrollment if they required aspirin 100 mg/day. Aspirin- naïve patients without gastroduodenal ulcer and Helicobacter pylori infection were randomized to receive teprenone 150 mg/day or placebo for 12 weeks. Primary outcome was assessed by the incidence rate of gastroduodenal ulcer. Secondary outcomes were assessed by the incidence rate of gastric mucosal injury, the improvement in modified Lanza score (MLS), gastrointestinal symptom rating scale (GSRS) and the change of gastric immunohistochemical expression for COX-1.Results: Total of 130 patients were randomized, 64 in teprenone group and 66 in placebo group. There was no incidence of ulcer after 12 weeks in both groups. Incidence of gastric mucosal injury was higher in placebo group than in teprenone group (40.0 vs. 13.38%, p = .039). Mean change of MLS was higher in placebo group than in teprenone group (0.767 ± 0.467 vs. 0.271 ± 0.158, p = .003). Scores of mucosal edema, hyperemia and hemorrhage and the change of GSRS were not different between the two groups. Change of COX-1 immunoreactive score was higher in placebo group than in teprenone group (2.433 ± 1.476 vs. 1.233 ± 0.955, p = .001). There were no treatment-related adverse events.Conclusions: Teprenone is effective in preventing gastric mucosal injury in patients taking LDA. Preventive effects of teprenone on LDA-related gastroduodenal ulcers require further investigation.

The road to recovery for vulnerable road users hospitalised for orthopaedic injury following an on-road crash

BackgroundPedestrians, cyclists and motorcyclists are vulnerable to serious injury due to limited external protective devices. Understanding the level of recovery, and differences between these road user groups, is an important step towards improved understanding of the burden of road trauma, and prioritisation of prevention efforts. This study aimed to characterise and describe patient-reported outcomes of vulnerable road users at 6 and 12 months following orthopaedic trauma. MethodsA registry-based cohort study was conducted using data from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and included pedestrians, cyclists and motorcyclists who were hospitalised for an orthopaedic injury following an on-road collision that occurred between January 2009 and December 2016. Outcomes were measured using the 3-level EuroQol 5 dimensions questionnaire (EQ-5D-3 L), Glasgow Outcome Scale – Extended (GOS-E) and return to work questions. Outcomes were collected at 6 and 12 months post-injury. Multivariable generalized estimating equations (GEE), adjusted for confounders, were used to compare outcomes between the road user groups over time. Results6186 orthopaedic trauma patients met the inclusion criteria during the 8-year period. Most patients were motorcyclists (42.8%) followed by cyclists (32.6%) and pedestrians (24.6%). Problems were most prevalent on the usual activities item of the EQ-5D-3 L at 6-months post-injury, and the pain/discomfort item of the EQ-5D-3 L at 12 months. The adjusted odds of reporting problems on all EQ-5D-3 L items were lower for cyclists when compared to pedestrians. Moreover, an average cyclist had a greater odds of a good recovery on the GOS-E, (AOR 2.75, 95% CI 2.33, 3.25) and a greater odds of returning to work (AOR = 3.13, 95% CI 2.46, 3.99) compared to an average pedestrian. ConclusionPedestrians and motorcyclists involved in on-road collisions experienced poorer patient-reported outcomes at 6 and 12 months post-injury when compared to cyclists. A focus on both primary injury prevention strategies, and investment in ongoing support and treatment to maximise recovery, is necessary to reduce the burden of road trauma for vulnerable road users.

State of the science: a scoping review of primary prevention of firearm injuries among children and adolescents.

Intentional and unintentional firearm injury is the second leading cause of death for youth, underscoring the need for effective primary prevention approaches that focus on increasing safe storage by caregivers and decreasing handling/carriage among youth. This article describes the state of the science for prevention of firearm injuries among children and adolescents. We applied PRISMA guidelines to present results from a scoping review using PubMed, Scopus, CINAHL, and CJ Abstracts for original research articles published between January 1, 1985 and March 1, 2018 in the U.S. focusing on primary screening or interventions for primary prevention of pediatric firearm injuries. In total, 46 articles met inclusion criteria: safe storage (23), screening (2), firearm handling/carriage/use (21). Across school, healthcare, and community settings, few evidenced-based programs exist, and data on firearm safety technologies are lacking. Programs have generally not employed rigorous designs, and/or assessed behavioral (e.g., carriage) or injury-related firearm outcomes. Evidenced-based prevention programs are needed to mitigate firearm morbidity and mortality among youth.

Heart Rate Variability in Sport Performance: Do Time of Day and Chronotype Play A Role?

A reliable non-invasive method to assess autonomic nervous system activity involves the evaluation of the time course of heart rate variability (HRV). HRV may vary in accordance with the degree and duration of training, and the circadian fluctuation of this variable is crucial for human health since the heart adapts to the needs of different activity levels during sleep phases or in the daytime. In the present review, time-of-day and chronotype effect on HRV in response to acute sessions of physical activity are discussed. Results are sparse and controversial; however, it seems that evening-type subjects have a higher perturbation of the autonomic nervous system (ANS), with slowed vagal reactivation and higher heart rate values in response to morning exercise than morning types. Conversely, both chronotype categories showed similar ANS activity during evening physical tasks, suggesting that this time of day seems to perturb the HRV circadian rhythm to a lesser extent. The control for chronotype and time-of-day effect represents a key strategy for individual training schedules, and, in perspective, for primary injury prevention.

Quantifying geographic barriers to trauma care: Urban-rural variation in prehospital mortality.

Few studies of trauma care access and quality account for prehospital injury mortality. Little is known about geographic variation in prehospital mortality or the impact of prehospital care on injury disparities. Using the Centers for Disease Control Wide-ranging Online Data for Epidemiologic Research database, we queried county-level incidence of prehospital injury mortality from 1999 to 2016. We linked mortality incidence with county-level urban-rural classifications from the National Center for Health Statistics and population data from the US Census Bureau. We used negative binomial regression to estimate the relationship between rurality and prehospital injury mortality, adjusting for county-level distribution of race, sex, age, income, and insurance coverage. Models were then stratified by injury mechanism (motor vehicle traffic [MVT] vs. penetrating) to determine if prehospital mortality rates varied by type of injury. Prehospital injury mortality rates were elevated for all urban-rural county classes, relative to large central metro counties, with incidence rate ratios (IRR) ranging from 1.25 (95% confidence interval [CI], 1.16-1.35) for fringe metro counties to 1.69 (95% CI, 1.58-1.82) for noncore counties. For MVT injury, IRRs for urban-rural classes compared with large central metro counties ranged from 2.02 (95% CI, 1.85-2.21) for fringe metro counties to 3.02 (95% CI, 2.76-3.30) to noncore counties. Incidence of prehospital mortality from penetrating injury was 14% higher for noncore counties compared to large central metro counties (IRR, 1.14; 95% CI, 1.05-1.23). There is substantial geographic variation in prehospital injury mortality in the United States, with risk of prehospital death increasing with rurality. Patterns of prehospital death associated with penetrating and MVT injuries suggest that improvements to both trauma center access, prehospital care, and primary injury prevention are essential to reduce preventable injury deaths.

The missing piece of the concussion discussion: primary prevention of mild traumatic brain injury in student athletes

The majority of concussion research has focused on timely diagnosis and treatment, yet little has been reported on primary prevention. The goal of this study is to examine the use of core training as a preventative tool. We performed a non-randomized prospective study involving high school athletes. They participated in a 10-week training session with exercises focused on increasing core strength [mobility, agility, stability, strength and flexibility (MASSf)]. Logs were kept of all concussions diagnosed using ImPACT concussion testing. Statistical analysis was done using Chi-square to calculate expected/observed frequency and Chi-squared test statistic, χ 2 . Test significance was accepted at a P 2 =9.84, corresponds to a P value of 0.0017. The MASSf program was repeated in the 2015 season with 2 concussions in 121 participants. Our study showed a statistically significant decrease in concussion rates after participating in MASSf training. This program shows a promise as a primary prevention method to reduce sports related concussions.

Current trends in sport injury prevention

Participation in sport and recreation has important positive implications for public health across the lifespan; however, the burden of sport-related musculoskeletal injury is significant, with the greatest risk being in youth and young adults. Moving upstream to primary prevention of injury is a public health priority that will have significant implications for reducing the long-term consequences of musculoskeletal injury including early post-traumatic osteoarthritis. The primary targets for the prevention of musculoskeletal injury in sport include neuromuscular training (NMT), rule modification, and equipment recommendations. Currently, there is significant high-quality evidence to support the widespread use of NMT warm up programs in team and youth sport, with an expected significant impact of reducing the risk of musculoskeletal injury by over 35%. Policy disallowing body checking in youth ice hockey has led to a >50% reduction in injuries, and rules limiting contact practice in youth American football has significant potential for injury prevention. There is evidence to support the use of bracing and taping in elite sport to reduce the risk of recurrent ankle sprain injury but not for use to prevent the primary injury, and wrist guards are protective of sprain injuries in snowboarding. Future research examining the maintenance of NMT programs across real-world sport and school settings, optimization of adherence, additional benefit of workload modification, and evaluation of rule changes in other sports is needed.

Systematic Selection of Key Logistic Regression Variables for Risk Prediction Analyses: A Five-Factor Maximum Model.

The evolution of clinical practice and medical technology has yielded an increasing number of clinical measures and tests to assess a patient's progression and return to sport readiness after injury. The plethora of available tests may be burdensome to clinicians in the absence of evidence that demonstrates the utility of a given measurement. Thus, there is a critical need to identify a discrete number of metrics to capture during clinical assessment to effectively and concisely guide patient care. The data sources included Pubmed and PMC Pubmed Central articles on the topic. Therefore, we present a systematic approach to injury risk analyses and how this concept may be used in algorithms for risk analyses for primary anterior cruciate ligament (ACL) injury in healthy athletes and patients after ACL reconstruction. In this article, we present the five-factor maximum model, which states that in any predictive model, a maximum of 5 variables will contribute in a meaningful manner to any risk factor analysis. We demonstrate how this model already exists for prevention of primary ACL injury, how this model may guide development of the second ACL injury risk analysis, and how the five-factor maximum model may be applied across the injury spectrum for development of the injury risk analysis.

Comprehensive training programme for judo players nine plus 9+: possible lower limb primary injury prevention

The First Decade of Web-Based Sports Injury Surveillance: Descriptive Epidemiology of Injuries in US High School Boys' Wrestling (2005-2006 Through 2013-2014) and National Collegiate Athletic Association Men's Wrestling (2004-2005 Through 2013-2014).

The advent of Web-based sports injury surveillance via programs such as the High School Reporting Information Online system and the National Collegiate Athletic Association Injury Surveillance Program has aided the acquisition of wrestling injury data. To describe the epidemiology of injuries sustained in high school boys' wrestling in the 2005-2006 through 2013-2014 academic years and collegiate men's wrestling in the 2004-2005 through 2013-2014 academic years using Web-based sports injury surveillance. Descriptive epidemiology study. Online injury surveillance from wrestling teams of high school boys (annual average = 100) and collegiate men (annual average = 11). Male wrestlers who participated in practices and competitions during the 2005-2006 through 2013-2014 academic years in high school or the 2004-2005 through 2013-2014 academic years in college. Athletic trainers collected time-loss (≥24 hours) injuries and exposure data during this time period. Injury rates per 1000 athlete-exposures (AEs), injury rate ratios with 95% confidence intervals, and injury proportions by body site and diagnosis were calculated. The High School Reporting Information Online documented 3376 time-loss injuries during 1 416 314 AEs; the National Collegiate Athletic Association Injury Surveillance Program documented 2387 time-loss injuries during 257 297 AEs. The total injury rate was higher in college than in high school (9.28 versus 2.38/1000 AEs; injury rate ratio = 3.89; 95% confidence interval = 3.69, 4.10). In high school, the most commonly injured body parts for both practices and competitions were the head/face (practices = 19.9%, competitions = 21.4%) and shoulder/clavicle (practices = 14.1%, competitions = 21.0%). In college, the most frequently injured body parts for both practices and competitions were the knee (practices = 16.7%, competitions = 30.4%) and head/face (practices = 12.1%, competitions = 14.6%). Injury rates were higher in collegiate than in high school players, and the types of injuries sustained most often differed. Based on these results, continued study of primary and secondary prevention of injury in wrestlers across levels of competition is warranted.

Paramedic involvement in health education within metropolitan, rural and remote Australia: a narrative review of the literature.

Objective A growing body of research indicates that paramedics may have a greater role to play in health care service provision, beyond the traditional models of emergency health care. The aim of this study was to identify and synthesise the literature pertaining to the role of paramedic-initiated health education within Australia, with specific consideration of metropolitan, rural and remote contexts. Methods A literature review was undertaken using the Ovid Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE and Scopus databases. The search time frame was limited from January 2007 to November 2017. The search was performed using key paramedic search terms in combination with keywords such as health education, rural, metropolitan, remote and Australia. Reference lists from relevant papers were also reviewed. Results Fourteen articles met the inclusion criteria for synthesis. Health education in the Australian paramedic context relates largely to expanded-scope paramedics, health promotion and the role of paramedics as key members of local communities. There were no studies specifically related to the paramedic role in health education, although many papers referred to health education as one of many roles paramedics engage in today. Conclusion This review highlights a broadening of paramedicine's traditional scope of practice, and an indication of how vital paramedics could be to local communities, particularly in rural and remote areas. An expanded role may help address health workforce sustainability problems in areas where health care provision is challenged by geographical constraints and low workforce numbers. What is known about the topic? A broadening of paramedicine's traditional scope of practice has been linked to improvements in health workforce sustainability problems in areas where health care provision is challenged by geographical constraints and low workforce numbers, such as rural and remote Australia. Health education, as well as health promotion, primary health care and chronic disease management, have been proposed as potential activities that paramedics could be well placed to participate in, contributing to the health and well-being of local communities. What does this paper add? This paper identifies and synthesises literature focusing on paramedic-initiated health education in the Australian context, assessing the current health education role of paramedics in metropolitan, rural and remote areas. It provides an understanding of different geographical areas that may benefit from expanded-scope prehospital practice, indicating that the involvement of paramedics in health education in Australia is significantly determined by their geographical place of work, reflecting the influence of the availability of healthcare resources on individual communities. What are the implications for practitioners? Today's paramedics fill broader roles than those encompassed within traditional models of prehospital care. Rural and remote communities facing increasing difficulty in obtaining health service provision appear to benefit strongly from the presence of expanded-scope paramedics trained in health promotion, primary injury prevention, chronic disease management and health education: this should be a consideration for medical and allied health practitioners in these areas. Australian paramedics are uniquely placed to 'fill the gaps' left by shortages of healthcare professionals in rural and remote areas of the country.

Ankle Bracing is Effective for Primary and Secondary Prevention of Acute Ankle Injuries in Athletes: A Systematic Review and Meta-Analyses.

Ankle bracing has been verified as being effective for secondary prevention of ankle injuries. However, new studies have recently been published that are not included in previous meta-analyses. Furthermore, the effects of bracing for primary prevention of ankle injuries are still unclear. The objective of this article was to systematically review the literature about the effectiveness of ankle bracing on primary and secondary prevention of acute ankle injuries in athletes. We searched PubMed, EMBASE, SPORTDiscus, CINAHL, and PEDro databases for eligible articles until July 2018. Randomized controlled trials that studied ankle bracing vs. no intervention for athletes were included. Risk of bias was assessed with the Cochrane Risk of Bias tool. Meta-analyses were conducted to study the effect of ankle bracing for primary and secondary prevention of ankle injuries. The Grading of Recommendation Assessment, Development, and Evaluation method was used to determine the quality of evidence. We included six randomized controlled trials. Significant risk ratios of 0.53 (95% confidence interval 0.32-0.88) and 0.37 (95% confidence interval 0.24-0.58) were found in favor of ankle bracing vs. no ankle bracing for primary (low quality of evidence, I2 = 77%) and secondary prevention (moderate quality of evidence, I2 = 0%) of acute ankle injuries. Numbers needed to treat were 26 and 12 for the primary and secondary prevention of acute ankle injuries. Ankle bracing is effective for primary and secondary prevention of acute ankle injuries among athletes. However, conclusions in regard to primary prevention should be drawn cautiously because of the low quality of evidence and significant heterogeneity.

Individualized Clinical Practice Guidelines for Pressure Injury Management: Development of an Integrated Multi-Modal Biomedical Information Resource.

BackgroundPressure ulcers (PU) and deep tissue injuries (DTI), collectively known as pressure injuries are serious complications causing staggering costs and human suffering with over 200 reported risk factors from many domains. Primary pressure injury prevention seeks to prevent the first incidence, while secondary PU/DTI prevention aims to decrease chronic recurrence. Clinical practice guidelines (CPG) combine evidence-based practice and expert opinion to aid clinicians in the goal of achieving best practices for primary and secondary prevention. The correction of all risk factors can be both overwhelming and impractical to implement in clinical practice. There is a need to develop practical clinical tools to prioritize the multiple recommendations of CPG, but there is limited guidance on how to prioritize based on individual cases. Bioinformatics platforms enable data management to support clinical decision support and user-interface development for complex clinical challenges such as pressure injury prevention care planning.ObjectiveThe central hypothesis of the study is that the individual’s risk factor profile can provide the basis for adaptive, personalized care planning for PU prevention based on CPG prioritization. The study objective is to develop the Spinal Cord Injury Pressure Ulcer and Deep Tissue Injury (SCIPUD+) Resource to support personalized care planning for primary and secondary PU/DTI prevention.MethodsThe study is employing a retrospective electronic health record (EHR) chart review of over 75 factors known to be relevant for pressure injury risk in individuals with a spinal cord injury (SCI) and routinely recorded in the EHR. We also perform tissue health assessments of a selected sub-group. A systems approach is being used to develop and validate the SCIPUD+ Resource incorporating the many risk factor domains associated with PU/DTI primary and secondary prevention, ranging from the individual’s environment to local tissue health. Our multiscale approach will leverage the strength of bioinformatics applied to an established national EHR system. A comprehensive model is being used to relate the primary outcome of interest (PU/DTI development) with over 75 PU/DTI risk factors using a retrospective chart review of 5000 individuals selected from the study cohort of more than 36,000 persons with SCI. A Spinal Cord Injury Pressure Ulcer and Deep Tissue Injury Ontology (SCIPUDO) is being developed to enable robust text-mining for data extraction from free-form notes.ResultsThe results from this study are pending.ConclusionsPU/DTI remains a highly significant source of morbidity for individuals with SCI. Personalized interactive care plans may decrease both initial PU formation and readmission rates for high-risk individuals. The project is using established EHR data to build a comprehensive, structured model of environmental, social and clinical pressure injury risk factors. The comprehensive SCIPUD+ health care tool will be used to relate the primary outcome of interest (pressure injury development) with covariates including environmental, social, clinical, personal and tissue health profiles as well as possible interactions among some of these covariates. The study will result in a validated tool for personalized implementation of CPG recommendations and has great potential to change the standard of care for PrI clinical practice by enabling clinicians to provide personalized application of CPG priorities tailored to the needs of each at-risk individual with SCI.Registered Report IdentifierRR1-10.2196/10871

How Air Ambulance Services Can Improve Care Delivered to Remote Indigenous Communities

Introduction Approximately fifty percent of Canada's Indigenous population resides in remote and rural communities, where life expectancy is five to seven years shorter than in the rest of Canada. Barriers to health care include, but are not limited to: low population density, long transportation and wait times, high rates of staff turnover, harsh weather climates, and inadequate human resources. Ornge is the air ambulance and critical care transport provider for the province of Ontario. Ontario is Canada's second largest province, with a landmass of more than 1 million km2, and a population of about 13 million people. Northern Ontario constitutes 87% of the land area of the province, but has less than 7% of the population. Ornge operates 12 bases across the province, and employs a fleet of 8 Pilatus PC-12 fixed wing aircraft and 11 AW 139 rotor wing aircraft to support the air ambulance transport needs of the province. As well, Ornge utilizes contract air carriers to provide transport for predominantly low acuity patients. We hypothesized that air ambulance services have the medical, logistical, educational, and technological and data capabilities to improve access to care for remote Indigenous communities. Increasing involvement of air ambulance services in delivering health care to remote Indigenous communities will improve patient outcomes and represent an opportunity for air ambulance services to expand their scope of work. Methods Ornge has developed a five-part strategy to help improve access to care for Indigenous communities. Results 1. Telemedicine: Over the past year, Ornge has conducted approximately 75 telemedicine consultations with the nurses servicing four remote indigenous communities. Survey data from the nurses has uniformly been extremely positive of the value of the telemedicine support. 2. Point of Care Lab Tests: Over the past six months, 58 patients within two communities have benefitted from point of care lab tests supplied by Ornge. Patient care has been improved dramatically and unnecessary transports have been prevented. 3. Education: Ornge has delivered educational sessions to nurses and doctors servicing these remote communities. This has improved the working relationships between all parties. As well, Ornge has helped develop a proposal to train indigenous members as first responders within seven remote communities. 4. Outreach: Ornge has delivered three sessions of first aid/cpr and "Stop the Bleed" training to Indigenous youth. As well, Ornge is now delivering Primary and Secondary Injury and Opioid prevention sessions to Indigenous Youth. 5. Data: Stakeholders are now using Ornge data to help identify strategies to improve access to care for Indigenous communities. Conclusion Air ambulance services have the expertise and capabilities to help improve access to care for remote Indigenous communities. This represents an area of potential opportunity for air ambulance services. Expanding the mandate of air ambulance services to improving access to care to these remote communities can help improve patient outcomes, allow for care closer to home, and allows for accurate triaging of air ambulance assets in a relative resource-poor environment.

Changes in the sensorimotor system and semitendinosus muscle morphometry after arthroscopic anterior cruciate ligament reconstruction: a prospective cohort study with 1-year follow-up.

To evaluate the time course of sensorimotor integration processes involved in balance capability during 1-year follow-up after arthroscopic anterior cruciate ligament (ACL) reconstruction. To evaluate whether an association exists between balance performance and semitendinosus muscle morphometry features. Twenty-seven patients (mean age 29.6 ± 10.8years) were prospectively followed with stabilometry and ultrasound at 3months (T0), 6months (T1), and 1year (T2) after arthroscopic ACL reconstruction. Body sway and sensorimotor integration processes were evaluated by calculating the percentage difference of sway (PDS) on two surface conditions. A significant difference in PDS was observed over time (p < 0.001). The interaction "Time × Condition" showed significant differences (p = 0.02), with worse performance on the compliant than the firm surface. There was a significant difference in CSA (p < 0.001), MT (p < 0.001), and %HRD (p < 0.001) over time. The interaction "Time*side" was significant for CSA (p = 0.02) and %HRD (p = 0.01). A negative correlation between PDS on compliant surface and CSA was measured at 3- (r = - 0.71, n = 27, p < 0.001) and 6-month post-surgery (r = - 0.47, n = 27, p = 0.013). Balance was regained within the first 6months after surgery, while morphometry of the semitendinosus muscle improved mostly between 6 and 12months in patients who returned to sports activities. Balance capabilities paralleled semitendinosus muscle morphometry improvements. The instrumental assessment of sensorimotor integration processes is relevant in clinical practice as screening tests for primary and secondary prevention of ACL injury. Prospective studies, Level II.

Firearm Safety: A Survey on Practice Patterns, Knowledge and Opinions of Pediatric Emergency Medicine Providers

Background and Objectives: Firearm injuries continue to be one of the top three leading causes of death in American youth, and access to firearms remains an important focus for primary injury prevention efforts in children. Emergency departments (EDs) often serve as a center for screening and education on injury prevention as injuries are the most common reason for pediatric ED visits. Our study sought to examine the knowledge, opinions, and practice patterns of pediatric emergency medicine (PEM) providers in regard to firearm safety counseling and assessment in the ED. Methods: We conducted a prospective cross-sectional …

Current Topics in the Management of Acute Traumatic Spinal Cord Injury.

Acute traumatic spinal cord injury (SCI) affects more than 250,000 people in the USA, with approximately 17,000 new cases each year. It continues to be one of the most significant causes of trauma-related morbidity and mortality. Despite the introduction of primary injury prevention education and vehicle safety devices, such as airbags and passive restraint systems, traumatic SCI continues to have a substantial impact on the healthcare system. Over the last three decades, there have been considerable advancements in the management of patients with traumatic SCI. The advent of spinal instrumentation has improved the surgical treatment of spinal fractures and the ability to manage SCI patients with spinal mechanical instability. There has been a concomitant improvement in the nonsurgical care of these patients with particular focus on care delivered in the pre-hospital, emergency room, and intensive care unit (ICU) settings. This article represents an overview of the critical aspects of contemporary traumatic SCI care and notes areas where further research inquiries are needed. We review the pre-hospital management of a patient with an acute SCI, including triage, immobilization, and transportation. Upon arrival to the definitive treatment facility, we review initial evaluation and management steps, including initial neurological assessment, radiographic assessment, cervical collar clearance protocols, and closed reduction of cervical fracture/dislocation injuries. Finally, we review ICU issues including airway, hemodynamic, and pharmacological management, as well as future directions of care.
