RESUMO
BACKGROUND: The emergency department (ED) is the first point of care for many patients with concussion, and post-concussion syndrome can impact vocational outcomes like successful return to work. Evaluation of concussion in general adult populations is needed. AIMS: To document the occurrence and outcomes of work-related concussion presenting to the ED for treatment. METHODS: This study enrolled adults presenting with concussion to three urban Canadian EDs. Baseline ED interviews, physician questionnaires and patient phone interviews at 30 and 90 days documented work-related events, ED management, discharge advice, patient adherence and symptom severity. Work-related injury and return to work were modelled using logistic or linear regression, as appropriate. RESULTS: Overall, 172 enrolled workers completed at least one follow-up. Work-related concussions were uncommon (n = 28). Most employees (80%) missed at least 1 day of work (median = 7; interquartile range: 3-14). Most (91%) employees returned to work within 90 days, while 41% reported persistent symptoms. Manual labour and self-reported history of attention deficit hyperactivity disorder were associated with work-related concussion, while days of missed work increased with marital status (divorced), history of sleep disorder and physician's advice to avoid work. CONCLUSION: Work-related concussions are infrequent; however, most workers who sustain a concussion will miss work, and many return while still experiencing symptoms. Work-related concussion and days of missed work are mainly affected by non-modifiable factors. Workers, employers and the workers' compensation system should take necessary precautions to ensure that workers return to work safely and successfully following a concussion.

OBJECTIVES: We study the association between changing residence and risks of attempted suicide and violent assault injury in Alberta, Canada. Our primary objective is to understand whether a change in residence between urban, rural and semiurban areas is associated with increased risk of intentional injury. METHODS: Study subjects are a cohort of residents linked to data on emergency department and inpatient hospital admissions between 1999 and 2010. We used generalised estimating equations to model the effects of changing residence on risk of intentional injury while controlling for the influence of age, sex, socio-economic status, Aboriginal status and history of intentional injury. RESULTS: Changing residence is associated with an increase in the risk of both attempted suicide and violent assault injury. In the case of attempted suicide, this effect is strongest for persons between 20 and 35â years of age. For violent assault injuries, persons from rural regions that have recently moved to urban regions have higher risk of injuries, and women of rural origin are at higher risk of violent assault injury than women of urban origin. CONCLUSIONS: Our findings reveal an association between risk of intentional injuries and change of residence adjusting for geographical differences in injury risk. These findings suggest that intentional injury risk is associated with change in community at intraregional scales and that these populations may benefit from support that helps integrate them into their new communities.

BACKGROUND: The international classification of diseases version 10 (ICD-10) uses alphanumeric expanded codes and external cause of injury codes (E-codes). OBJECTIVE: To examine the reliability and validity of emergency department (ED) coders in applying E-codes in ICD-9 and -10. METHODS: Bicycle and pedestrian injuries were identified from the ED information system from one period before and two periods after transition from ICD-9 to -10 coding. Overall, 180 randomly selected bicycle and pedestrian injury charts were reviewed as the reference standard (RS). Original E-codes assigned by ED coders (ICD-9 in 2001 and ICD-10 in 2004 and 2007) were compared with charts (validity) and also to ICD-9 and -10 codes assigned from RS chart review, to each case by an independent (IND) coder (reliability). Sensitivity, specificity, simple, and chance-corrected agreements (κ statistics) were calculated. RESULTS: Sensitivity of E-coding bicycle injuries by the IND coder in comparison with the RS ranged from 95.1% (95% CI 86.3 to 99.0) to 100% (95% CI 94.0 to 100.0) for both ICD-9 and -10. Sensitivity of ED coders in E-coding bicycle injuries ranged from 90.2% (95% CI 79.8 to 96.3) to 96.7% (95% CI 88.5 to 99.6). The sensitivity estimates for the IND coder ranged from 25.0% (95% CI 14.7 to 37.9) to 45.0% (95% CI 32.1 to 58.4) for pedestrian injuries for both ICD-9 and -10. CONCLUSION: Bicycle injuries are coded in a reliable and valid manner; however, pedestrian injuries are often miscoded as falls. These results have important implications for injury surveillance research.

BACKGROUND: As utilization rates for total joint arthroplasty increase, there is a hesitancy to perform this surgery on very old patients. The objective of this prospective study was to compare pain, functional, and health-related quality-of-life outcomes after total hip and total knee arthroplasty in an older patient group (> or =80 years) and a representative younger patient group (55-79 years). METHODS: In an inception community-based cohort within a Canadian health care system, 454 patients who received primary total hip arthroplasty (n = 197) or total knee arthroplasty (n = 257) were evaluated within a month prior to surgery and 6 months postoperatively. Pain, function, and health-related quality of life were evaluated with the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the 36-Item Short-Form Health Survey (SF-36). RESULTS: There were no age-related differences in joint pain, function, or quality-of-life measures preoperatively or 6 months postoperatively. Furthermore, after adjusting for potential confounding effects, age was not a significant determinant of pain or function. Although those in the older and younger groups had comparable numbers of comorbid conditions and complications, those in the older group were more likely to be transferred to a rehabilitation facility than younger patients. Regardless of age, patients did not achieve comparable overall physical health when matched with the general population for age and sex. CONCLUSIONS: With increasing life expectancy and elective surgery improving quality of life, age alone is not a factor that affects the outcome of joint arthroplasty and should not be a limiting factor when considering who should receive this surgery.

INTRODUCTION: Participation in ice hockey by women is increasing in many parts of North America; however, research into injuries and the patterns of injury among female players associated with this activity is limited. PURPOSE: The purpose of this research was to examine the incidence and nature of injuries suffered by female recreational ice hockey players. METHODS: This prospective study followed 314 female players from 33 teams in Edmonton, Canada, during the 1997-1998 hockey season. Injury and game attendance data were collected using monthly telephone interviews throughout the season. Diagnostic information for individuals who received medical treatment was solicited from the attending health professional. RESULTS: A total of 102 players reported a total of 125 injuries for a rate 7.5 injuries/1000 player exposures. The anatomic region most often injured was the lower extremity (31.2%), and the most common diagnosis was sprain/strain (52.0%). The predominant injury mechanism was player contact, either as a result of collision with another player or a body check (40.0%). Of all injuries, 65.6% occurred during league games, 27.2% during play-off, tournament, or exhibition games, and 7.2% during practices. Although less than 1% of injuries resulted in hospitalization, 17.6% of injuries resulted in an absence from hockey of 8 or more days. CONCLUSION: The diagnostic and anatomic distribution of injury in the women's hockey league was similar to that in leagues where full facial protection is mandatory. The observed injury rate was lower than the rates reported for male recreational and collegiate ice hockey players. Female recreational ice hockey players are at risk for injuries and further research is required to identify areas for injury prevention.

OBJECTIVES: Sledding is a common recreational activity in northern communities. The objective of this study was to examine the frequency and nature of sledding injuries (SIs) in patients presenting to emergency departments (EDs). METHODS: The data were derived from a cohort of patients treated at all five EDs in an urban Canadian health region over a two-year period. Following chart review, consenting patients were interviewed by telephone about their sledding activities and the circumstances surrounding the injury. RESULTS: Three hundred twenty-eight patients were correctly coded as having SIs, with 212 patients (65%) reached during the follow-up survey. The median age of those with SIs was 12 years (IQR = 8, 21), and 206 (59%) were male. Injury rates peaked in the 10--14-year age group (87/100,000) for boys and in the 5--9-year age group (75/100,000) for girls. Most patients stated they were drivers (75%), fewer than half were thrown from the sled (42%), and fewer than half (44%) were sledding on community-designated sledding hills at the time of injury. Injuries to the lower extremity (32%), upper extremity (31%), and head (13%) were most common. Thirty-seven (11%) patients with SIs were admitted to hospital vs 4% of patients with other sports/recreation injuries (p < 0.05). CONCLUSIONS: Sledding injuries are common and potentially serious wintertime injuries in northern communities, involving primarily younger patients, with a large pre-adolescent group. However, older sledders (>20 years) have poorer outcomes (hospitalization, lost time from work/school) than their younger counterparts. The SIs treated in the ED appear to lead to hospitalization more frequently than other types of sport/recreation injury, and injury prevention strategies appear warranted.

The 1996 Alberta Sport and Recreation Injury Survey is a retrospective study describing the annual incidence of injuries in the province of Alberta resulting from sport and recreational involvement. Data was collected by means of a telephone survey using random digit dialing techniques to obtain a representative sample of Albertans in the winter of 1995-96. The sample produced a total of 3,790 respondents from 1,478 households evenly split between genders, with an age range of 6 to 93 years. The survey asked information regarding medically attended, non-fatal injuries resulting from sport and recreational activities. Findings reveal an annual incidence of sport or recreational injuries of 11%. Among those reporting a sport or recreational injury, the most common types of injuries were a sprained/torn ligament (31%), strained/pulled muscle (19%), and fracture (13%). The most common bodily locations of injuries were the knees (21%) and the ankle (14%).

INTRODUCTION: Women's ice hockey is a rapidly growing sport, however little is known about the injuries sustained by this group of athletes. PURPOSE: The objective of this research was to identify risk factors associated with injury among female recreational ice hockey players. METHODS: This prospective study followed players from two women's ice hockey leagues in Edmonton, Canada during the 1997-98 hockey season. The occurrence of injuries was monitored during the season through standardized telephone follow-up. Risk factors were determined using multiple logistic regression. RESULTS: The initial study sample consisted of 314 players, however as the season progressed 19 (6%) were lost to follow-up. The results of the study are based on 295 (94%) participants. A total of 125 injuries were reported; the injury rate was 7.5 injuries/1,000 player-exposures. Risk factors found to be significantly related to the occurrence of injury were: injury in the past year (OR= 1.57), more than 5 years of hockey experience (OR=1.49), and high exposure level (OR=1.41). CONCLUSION: This research is the first to quantify personal risk factors associated with injury among female recreational ice hockey players. A sports injury in the previous 12 months appears to be highly associated with injury and further research is required to more fully understand this relationship. The importance of controlling for level of exposure when investigating risk factors for sports injury was demonstrated.

OBJECTIVES: Our goal was to determine the effectiveness of an intervention aimed at improving the emergency department (ED) documentation of pediatric injuries. METHODS: All physicians and nursing staff in the ED of an urban teaching hospital and trauma centre underwent focused injury surveillance training and were instructed how to document 14 injury-specific data elements. Pocket reminder cards were provided, and pediatric injury charts were flagged. Subsequently, random samples of pediatric injury charts were analyzed from a 3-month period prior to the intervention and from the corresponding months after the intervention. Post-intervention documentation was compared to pre-intervention documentation for the 14 pre-defined data elements. RESULTS: Six of the 14 data elements were charted more frequently, and 2 less frequently during the post-intervention phase. Odds ratios ranged from 4.59 (95%CI, 3.40 to 6.19) for charting "the presence of an adult observer" to 0.09 (95%CI, 0.01 to 0.76) for charting "sports equipment related to the injury." The "flagging" of injury charts, as a visual reminder for clinicians to document injury data, seemed to be the most effective component of the intervention. CONCLUSION: A simple intervention, consisting of staff training, chart modification, and visual flagging of charts, can increase the amount of injury information documented by ED clinicians. Efforts to improve ED charting are most likely to succeed if they include visual prompts for clinicians.
RESUMO
BACKGROUND: Bicycle helmets reduce fatal and non-fatal head and face injuries. This study evaluated the effect of mandatory bicycle helmet legislation targeted at those less than 18 years old on helmet use for all ages in Alberta. METHODS: Two comparable studies were conducted two years before and four years after the introduction of helmet legislation in Alberta in 2002. Bicyclists were observed in randomly selected sites in Calgary and Edmonton and eight smaller communities from June to October. Helmet wearing and rider characteristics were recorded by trained observers. Poisson regression adjusting for clustering by site was used to obtain helmet prevalence (HP) and prevalence ratio (PR) (2006 vs. 2000) estimates. RESULTS: There were 4002 bicyclists observed in 2000 and 5365 in 2006. Overall, HP changed from 75% to 92% among children, 30% to 63% among adolescents and 52% to 55% among adults. Controlling for city, location, companionship, neighborhood age proportion <18, socioeconomic status, and weather conditions, helmet use increased 29% among children (PR = 1.29; 95% CI: 1.20-1.39), over 2-fold among adolescents (PR 2.12; 95% CI: 1.75-2.56), and 14% among adults: (PR = 1.14; CI: 1.02-1.27). CONCLUSIONS: Bicycle helmet legislation was associated with a greater increase in helmet use among the target age group (<18). Though HP increased over 2-fold among adolescents to an estimated 63% in 2006, this percentage was approximately 30% lower than among children <13.

The objective of this study was to determine the impact of the New South Wales Rural Hearing Conservation Program on the implementation of personal hearing protection (PHP) and noise management strategies among farmers who had participated in this program in New South Wales, Australia. A follow-up survey of a random sample of people screened through the New South Wales Rural Hearing Conservation Program was linked to their baseline data. The use of PHP at baseline was compared to use at follow-up in four specific scenarios: use with non-cabbed tractors, with chainsaws, with firearms, and in workshops. For non-cabbed tractors, the net gain in PHP use was 13.3%; the net gain was 20.8% for chainsaws, 6.7% for firearms, and 21.3% for workshops. Older farmers and those with a family history of hearing loss were less likely to maintain or improve PHP use. Those with severe hearing loss, males, and participants reporting hearing problems in situations where background noise was present were more likely to maintain or improve PHP use. Forty-one percent of farmers had initiated other strategies to reduce noise exposure beyond the use of PHP, which included engineering, maintenance, and noise avoidance solutions. The early (hopefully) identification of hearing deficit in farmers and farm workers can help promote behavior change and help reinforce a farm culture that supports hearing conservation. The continuation and expansion of hearing screening programs such as these should be encouraged as basic public health strategy in farming communities.

BACKGROUND: Suicide among seniors is a significant health problem in north America, particularly for men in whom the rates rise steadily after 50 years of age. The goal of this study was to examine elder suicides identified from a large population-based database using case-control methods to determine disease and medication factors related to suicide. METHODS: A population-based 1 : 5 case-control study was conducted comparing seniors aged 66 years and older who had died by suicide with age and sex-matched controls. Case data were obtained through British Columbia (BC) Vital Statistics, whereas controls were randomly selected from the BC Health Insurance Registry. Cases and controls were linked to the provincial PharmaCare database to determine medication use and the provincial Physician Claims and Inpatient Hospitalization databases to determine co-morbidity. RESULTS: Between 1993 and 2002 a total of 602 seniors died by suicide in BC giving an annual rate of 13.2 per 100,000. Firearms were the most common mechanism (28%), followed by hanging/suffocation (25%), self-poisoning (21%), and jumping from height (7%). In the adjusted logistic model, variables related to suicide included: lower socioeconomic status, depression/psychosis, neurosis, stroke, cancer, liver disease, parasuicide, benzodiazepine use, narcotic pain killer use and diuretic use. There was an elevated risk for those prescribed inappropriate benzodiazepines and for those using strong narcotic pain killers. CONCLUSION: This study is consistent with previous studies that have identified a relationship between medical or psychiatric co-morbidity and suicide in seniors. In addition, new and potentially useful information confirms that certain types and dosages of benzodiazepines are harmful to seniors and their use should be avoided.

BACKGROUND: Agricultural work continues to be a dangerous occupation. Older farmers experience high risks for work-related injury. The purpose of this research was to determine if there is a relationship between medication use and injury among older male farmers in Alberta. METHODS: Using probabilistic linkage between an Alberta Agriculture government registry of farm operators and the Alberta Health Plan registry file, older farmers (aged 66 and older) were identified. Farm related injuries were identified using an E-code search of both hospitalization and emergency department separations for a 3-year period. Cases were matched to controls on age, geographic health region, and index injury date at a ratio of 1:5. Co-morbidity and medication use for each of the cases and controls were derived from population based health system utilization files. Conditional logistic regression was used to determine which medications were related to injury. RESULTS: Overall, a total of 282 farm related injuries were suffered by the linked group. Controlling for co-morbidity, farmers who had stopped taking narcotic pain killers (OR = 9.37 [95% CI:4.95, 17.72]) and non-steroidal anti-inflammatories (OR = 2.40 [95% CI:1.43, 4.03]) 30 days prior to the date of injury were at risk of injury. Those farmers taking sedatives up until the date of injury were also at risk (OR = 3.01 [95 CI:1.39, 6.52]). In addition, those suffering from incontinence/urinary tract disorders (OR = 2.95 [95% CI:1.30, 6.71]), and prior injury (OR = 1.42 [95% CI:1.04, 1.95]) were also at greater risk of injury. CONCLUSIONS: The relationship of medication use and injury in this population is different from those observed in studies of falls in older persons. We hypothesize that distraction from either pain or co-morbidity may play an important role in the etiology of injuries suffered in this active older working population. Further investigations in this area are required to confirm these findings.

A nighttime roadside survey of rural Alberta drivers was conducted to quantify the nature and extent of impaired driving on Alberta's rural roads during nighttime. The survey also sought to describe driver demographics and information about the trip, such as origin and destination, among rural Alberta's nighttime drivers. Surveys were administered to drivers of vehicles that were randomly sampled at rural locations in Alberta between the hours of 10:00 PM and 4:00 AM between 22 August and 1 September 2001. Drivers who agreed to participate were asked a series of short questions. The interview concluded with the driver providing a breath sample to measure the driver's BAC level. Of the drivers surveyed, 3% had a BAC that was over the legal limit of 80 mg%. A total of 13% of drivers tested had detectable amounts of alcohol in their system.

OBJECTIVE: To evaluate the impact of regionalization on the outcomes of 16 surgical procedures performed in the Capital Health Region (Edmonton) of Alberta. DESIGN: A computer search of hospital discharge abstracts coded for the Canadian Institute for Health Information. SETTING: Two major hospitals in Edmonton. PATIENTS: The study population comprised 9250 patients (9727 procedures [4524, pre-regionalization, 5203 post-regionalization]) who underwent any of 16 major procedures in the 2 years before and the 2 years after restructuring. OUTCOME MEASURES: Demographic data, Charlson's comorbidity index, number of urgent and emergent cases, death rate, average length of hospital stay and the readmission rate. RESULTS: The post-regionalization patient group was slightly older, had a higher comorbidity index, and fewer urgent and emergent cases. The case volume increased by 15%, and 43.6% of patients used some form of community-based health care services. The median length of hospital stay decreased from 8.0 days pre-regionalization to 7.0 days post-regionalization (p < 0.001). Overall and for specific procedures the death rate was unchanged (3.1% pre-regionalization, 2.4% post-regionalization, p = 0.06). The readmission rates were similar for both groups (8.0% versus 7.0%). CONCLUSIONS: The consolidation of these 16 major surgical procedures had minimal impact on death and readmission rates even though patients in the post-regionalization group were slightly older and had greater comorbidity. There was a significant decline in the length of hospital stay, which occurred nationally over the same period, and a corresponding increase in the use of community-based services.

The purpose of this study was to determine factors related to a return to work following the completion of a work hardening program. Data from the Workers' Compensation Board of Alberta Millard Rehabilitation Centre for 1527 discharges, collected over 22 months, were examined retrospectively. Factors related to return to work were compared bivariately using logistic regression procedures. A multiple logistic regression model for return to work was also determined. The principle predictor of return to work was job-attached status to the pre-injury employer. Other factors related to return to work were education, primary diagnosis, injury to admission time, job attachment to the pre-accident employer, employer's annual payroll, and vocational direction. Due to the strength of the association between job-attached status to the pre-injury employer and a return to work, it was concluded that attempts to maintain this relationship should be a priority for rehabilitation providers and insurance carriers.
RESUMO
The aim of this study was to determine the incidence and complications related to manual removal of the placenta in a regional hospital in Australia. The study was carried out at the Goulburn Valley Base Hospital in Shepparton. The hospital medical records were reviewed from 1992 to 1999. A total of 3734 singleton live vaginal deliveries took place during the 7-year study period. The placenta was removed manually in 114 women (3%). For a control group, a series of 113 women who had singleton live vaginal deliveries from the same period were chosen at random. The case and control groups were similar in age, parity, and gravidity. A previous history of retained placenta and a history of preterm delivery in the current pregnancy were significantly related to retained placenta (OR 9.8 [95% CI 1.1-85.5] and OR 5.6 [95% CI 1.1-26.8], respectively). The cases received significantly more blood transfusions than the control group (13% versus 0%). Decreased maternal age was also significantly related to retained placenta. There were also more post-delivery dilatation and curettage (D&C) operations and diagnosis of endomyometritis in the case group. However, these differences were not statistically significant. One woman, in the case group, had to have a hysterectomy due to placenta accreta.

OBJECTIVE: To quantify the magnitude of change seen with pain, function, and quality of life outcomes 6 months after total hip and knee arthroplasties (THA, TKA) within a community based cohort of a regional health district. METHODS: An inception cohort of 504 patients who received primary THA (228) or TKA (276) was prospectively followed. All patients resided in the community and were assessed within one month prior to surgery and 6 months postoperatively. Health related quality of life measures were evaluated with the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the Medical Outcome Survey Short Form SF-36. Perioperative factors were extracted from medical charts. Health services utilization data were collected from regional health databases. RESULTS: Over 75% of patients reported improvement in joint-specific pain and function, regardless of the type of joint replaced. Other health dimensions such as social function, bodily pain, physical function, vitality, and general health showed significant improvement after surgery. Those psychosocial dimensions with modest changes had baseline values comparable to age and sex adjusted normal values; whereas, bodily pain and physical function, which had large changes, had values lower than the normal values. Ninety-one percent of patients receiving THA were satisfied with their surgery, whereas 77% were satisfied with their TKA. The average length of stay was 7 days and the in-hospital complication rate was 0.34 per patient. CONCLUSION: Large improvements were reported for pain and function after joint arthroplasties, while small to moderate changes were seen in other areas related to quality of life. Patients with hip arthroplasties showed greater improvement in pain and function and were more satisfied with their outcomes than patients with knee arthroplasties. Although pain and function show large improvements, bodily pain and physical function were less than the values reported in the general population.

OBJECTIVE: To describe the frequency and circumstances of work-related, fatal injuries among older farmers in Canada (1991 to 1995). DESIGN: Descriptive, epidemiologic analysis of data from the Canadian Agricultural Injury Surveillance Program. SETTING: Canada. PARTICIPANTS: Farmers aged 60 and older who died from work-related injuries from 1991 through 1995. METHOD: Age-adjusted mortality rates were calculated using the Canadian farm population as a standard for people involved, mechanism of injury, and place and time of injury. MAIN FINDINGS: The 183 work-related fatalities observed produced an overall mortality rate of 32.8 per 100,000 population per year. Higher fatality rates were observed in Quebec and the Atlantic Provinces. Almost all of those who died (98%) were men. Farm owner-operators accounted for 82.8% of the deaths (where the relationship of the person to the farm owner was reported). Leading mechanisms of fatal injury included tractor rollovers, being struck or crushed by objects, and being run over by machinery. Many older farmers appeared to be working alone at the time of injury. CONCLUSIONS: The data suggest that older farmers died while performing tasks common to general farm work, that most were owner-operators, and that many were working alone at the time of death. Innovative ways to reduce work-related injuries in this population must be found.
