Patterns of injuries to children on public playgrounds

A Pilot Randomized Trial Evaluating the Cool 2 Be Safe Junior Playground Safety Program for Preschool Children

OBJECTIVE

Unintentional injury is the leading cause of death to children worldwide, and playgrounds pose a significant risk of injury. Those aged 5 and 6 years are particularly vulnerable to playground injuries. Previous interventions have typically targeted environmental modifications or increased supervision to reduce playground injuries; however, minimal research has focused on implementing behavioral interventions that seek to change children's safety knowledge and risk-taking behaviors on the playground. The current randomized trial addressed these gaps in the literature and sought to increase preschool children's hazard awareness skills and knowledge of unsafe playground behaviors and decrease their intentions to engage in risk-taking behaviors on the playground.

METHOD

A total of 77 children aged 5 and 6 years were tested at a laboratory on a university campus, using a parallel group design, with 38 randomized to the playground intervention group and 39 randomly assigned to a control group. The intervention was manualized and delivered to small groups of children (3-5) over several sessions.

RESULTS

Statistical analyses revealed significant group differences. Intervention experience led to significant increases in hazard awareness skills and knowledge of unsafe playground behaviors, and significant decreases in children's risk-taking behavioral intentions, whereas those in the control group showed no significant changes in these scores. Attention scores for those in the intervention group highlighted that the program content was successful in maintaining children's attention and engagement, and memory scores indicated excellent retention of lesson content.

CONCLUSION

The program shows promise in addressing the issue of unintentional playground injuries in young children.

Effect of Weather Conditions on the Pediatric Supracondylar Humerus Fracture Incidence

Background: Some environmental factors pose as risk factors for children's supracondylar humerus fractures. This study aimed to evaluate the relationship between weather conditions and pediatric supracondylar humerus fracture incidence.

Methods: A total of 310 patients aged <16 years, admitted to our hospital with supracondylar humerus fractures, were evaluated. We evaluated patients' age, and also, season, day, and weather conditions. The Turkish State Meteorological Service database was used for meteorological data and data was analysed statistically.

Results: Most cases occurred in the spring (28.1%, n=87) and summer (27.1%, n=84). Cases of older children (aged six years and older) with supracondylar humerus fractures were recorded in the summer season, while fracture cases in preschool-aged (younger than six years old) children were seen in the winter season.

Conclusion: We found that the overall incidence of pediatric supracondylar humerus fractures increased in spring and summer seasons. In addition, the fracture incidence in preschool- and school-aged children differed according to the season and temperature. Hence, the management of these fractures could also include the significance of weather conditions, making preventive measures more critical in the spring and summer seasons.

The feature assessment of the bone fractures in 1020 children and review of the literature

OBJECTIVE:

This study aims to collect data, which is a risk factor on bone fractures in children.

METHODS:

The study group consisted of 1020 children (n=282; 28% girls and n=738; 72% boys, with a mean age of 8.3 years) with a bone fracture. The age, gender, the month and the time of the day the fracture was sustained, mechanism of injury, feature of the fracture, the presence of coexisting injuries, and the method of treatment were recorded.

RESULTS:

Boys had approximately three times more fractures than girls. The fractures were found to be more prevalent in upper extremities (76.6%) and on its left side (56.0%), and the most commonly fractured bone was isolated radius (n=304; 32.1%); most frequently distal radius). The most prevalent lower-extremity fractures were to the femur (n=92; 31.7%). It was found that fractures occurred most frequently between the ages 3 and 6 (23.6%), and fractures in boys were most common among 13 to 15-year-old patients (n=216; 23.9%), whereas girls aged 3–6 years suffered the most fractures (n=103; 30.8%). The fractures were more common in spring (n=384; 31.0%) and summer (n=365; 29.5%). The time slot bone fractures occurred the most was from 12:00 pm to 5:00 pm (n=824; 66.6%). The most common reasons for fractures were outdoor falls (n=705; 57.0%), and indoor falls (n=239; 19.3%), respectively. Bone fractures co-occurred with head trauma the most (n=30; 42.3%). Fifty-nine patients (5.8%) had epiphysis fracture. 51 patients (5.0%) had open fractures. Five hundred ninety-two patients (58.0%) were given outpatient treatment.

CONCLUSION:

Child bone fractures are most frequently seen in the left upper extremity in 10–15-year-old boys, occurring as a result of outdoor falls in the afternoon in the spring and summer months. Bones located in the wrist, hand, and elbow have been found to be much more vulnerable to fractures. Many of the fractures were treated by conservative methods. Creating a safe environment for children is the most effective method of injury control. Necessary arrangements should be made for the safety of children in the environment and at home. Continuing education and legal regulations play an active role in injury control.

Outdoor Fitness Equipment Usage Behaviors in Natural Settings

Outdoor fitness equipment (OFE) areas have become a popular form of built environment infrastructure in public open spaces as a means to improve public health through increased physical activity. However, the benefits of using OFE are not consistent, and several OFE accidents have been reported. In this study, we videotaped how OFE users operate OFE in parks and selected four types of popular OFE (the waist twister, air walker, ski machine, and waist/back massager) for video content analysis. Furthermore, we established coding schemes and compared results with the instructions provided by OFE manufacturers. The results revealed various usage behaviors for the same OFE types. In addition, we observed that a significant portion of user behaviors did not follow manufacturers' instructions, which might pose potential risks or actually cause injuries. Children are especially prone to act improperly. This study provides empirical evidence indicating the existence of potential safety risks due to inappropriate usage behaviors that might lead to accidents and injuries while using OFE. This study provides crucial information that can be used to evaluate the effectiveness of OFE and to develop future park or open space initiatives.

A systematic review of the risk factors and interventions for the prevention of playground injuries

OBJECTIVES

The primary objectives of this work were to (1) identify the risk and/or protective factors associated with playground injuries among children less than 18 years of age and (2) identify interventions/programs/policies aimed at preventing playground-related injuries among children less than 18 years of age. Secondary objectives include a summary of the data that reflect alignment with current playground standards.

METHODS

For the primary outcome, 4 databases and 12 online resources were systematically searched to include observational and experimental studies examining risk and/or protective factors or interventions associated with playground injury or outcomes related to playground injury (e.g., risky playground behaviour). Data extraction included study design, participants, outcome, exposure or intervention, data analysis, and effect estimates. The quality of evidence for all studies was assessed using the Downs and Black criteria.

RESULTS

This review included studies of moderate quality, revealing a number of risk factors and effective interventions for playground injury. Risk factors included absence of handrails and guardrails on playground equipment, non-impact-absorbing surfacing, and critical fall heights. Effective interventions included modifying playground surfacing and reducing equipment height to less than 1.5 m.

CONCLUSION

Equipment- and structure-based playgrounds should adhere to and maintain playground standards in order to reduce the risk of serious injury. Organizations responsible for installing and maintaining playgrounds should consider alternative play spaces that allow children to play outdoors, in a natural environment that supports healthy child development and promotes physical activity.

Playground Equipment Related Injuries in Preschool-Aged Children: Emergency Department-based Injury In-depth Surveillance

In this study, we investigated playground equipment related injuries in preschool-aged children. This was a retrospective observational study using Emergency Department based Injury In-depth Surveillance, (2011-2014). We included the preschool-aged children with playground equipment related injuries. We surveyed the mechanism and incidence of injuries, and estimated the odds ratio (OR) of traumatic brain injury (TBI) and upper/lower extremities fracture. There were 6,110 patients, mean age was 4.14 ± 1.95 years old. Slide and swing related injuries were 2,475 (40.5%) and 1,102 (18.0%). Fall down (48.5%) was the most common mechanism. The OR of TBI in children 0-2 years old was 1.88 times higher than children 3-7 years old, and in swing was 4.72 (OR, 4.72; 95% confidence interval [CI], 2.37-9.40) times higher than seesaw. The OR of upper extremity fracture in children 3-7 years old was 3.07 times higher than children 0-2 years old, and in climbing was 2.03 (OR, 2.03; 95% CI, 1.63-2.52) times higher than swing. The OR of lower extremity fractures in horizontal bars, tightropes, and trampolines was 2.95 (OR, 2.95; 95% CI, 1.55-5.61) times higher than swing. The most common mechanism and playground equipment were fall down and slide. TBI was associated to younger children (0-2 years old) and swing. Fracture of upper extremities was associated to older children (3-7 years old) and climbing. Fracture of lower extremities was associated to others such as horizontal bars, tightropes, and trampolines.

An evaluation of the Cool 2 Be Safe program: an evidence-based community-disseminated program to positively impact children's beliefs about injury risk on playgrounds

Falls from playground equipment during play are a leading cause of injury for elementary school children. Changes to playground design and surfacing materials can reduce injury risk. However, there is also a need for intervention programs to reduce risky play behaviors by children that are associated with falls. The Cool 2 Be Safe program was developed based on past research that identified effective strategies for targeting injury beliefs that predict risk behaviors on playgrounds among individually tested elementary school children. The current study evaluated the effectiveness of delivering these activities as an integrated program and in a group format in after school programs organized by Boys and Girls Clubs of Canada. The clubs were provided all program and extensive training materials, and a webinar training session was conducted for facilitators. Observations of sessions provided data on fidelity of program delivery. Pre- and post-intervention data assessing children's injury beliefs were collected via survey, with children participating in four structured activity sessions in small groups between premeasures and post-measures. The training materials proved to be quite effective; observational data indicated 88 % compliance with the procedures. Comparing children's pre- and post-responses revealed positive changes in injury-risk beliefs that have been shown to predict reduced risk taking on playgrounds. This initial evaluation suggests that the Cool 2 Be Safe community program holds much promise as a means for addressing the issue of fall-risk behaviors by elementary school children on playgrounds.

Severity of playground-related fractures: more than just playground factors?

INTRODUCTION

Despite the establishment of playground safety standards, playground-related injuries are still a significant cause of extremity fractures in Singapore. This prospective study evaluates the dimensions and characteristics of our playgrounds, and their effect on fracture severity in an Asian population. We aim to correlate various playground risk factors with severity of the fractures and give recommendations on future safety standards. Our data also allows us to compare the demographics of patients in our study group with that collected in our earlier study in 2004.

METHODS

From June 2005 to 2006, children who presented with extremity fractures to KK Women's and Children's Hospital after a playground injury were enrolled. Their clinical data were collected prospectively. Relevant playground details were collected on-site independently by another investigator. For analysis of severity, fractures were "major" if they required reduction or operative fixation and were "minor" if they did not.

RESULTS

Supervision at time of injury, especially from the child's parents or siblings, resulted in a lower likelihood of "major" fractures (P=0.002, likelihood ratio=1.97). Conversely, supervision from grandparents or maids was found to result in a higher likelihood of "major" fractures. Increased weight of patients was directly related to severity of fractures (P=0.000), and a body mass index (BMI) of less than 19.8 kg/m resulted in lower likelihood of "major" fractures (P=0.010, likelihood ratio=2.22). Height of equipments and other playground-related factors were not linked to severity of fractures.

CONCLUSIONS

Supervision at the playground, preferably from the child's parents or siblings, and keeping a child's BMI within limits as guided by the BMI charts, may potentially reduce the occurrence of severe fractures.

Only kids who are fools would do that! Peer social norms influence children's risk-taking decisions

OBJECTIVES

The current research examined the impact of peer social norms on the physical risk-taking decisions of elementary-school children.

METHOD

Children 6-12 years of age completed a novel video-viewing decision task in which they observed risk and non-risk child behaviors on a playground and, after each behavior, indicated their willingness to model each of the behaviors in their own video, both before and after exposure to peer-communicated social norms (encouragement, discouragement).

RESULTS

Exposure to peer social norms resulted in significant changes in risk taking, with changes predicted from ratings of perceived social norms and appraisals of injury vulnerability and severity.

CONCLUSION

Exposure to peer social norms can provide another means by which injury prevention programs can aim to reduce injury-risk behaviors among school-age children.

Safety assessment in the urban park environment in Alborz Province, Iran

Urban parks, as one of the recreational and sports sectors, could cause serious injuries among different ages if the safety issues in their design are not considered. These injuries can result from the equipment in the park, including play and sports equipment, or even from environmental factors, too. Lack of safety benchmark in parks will impact on the development of future proposals. In this article, attempts are made to survey the important safety factors in the urban parks including playgrounds, fitness equipment, pedestrian surface and environmental factors into a risk assessment. Hence, a checklist of safety factors was used. A Yes or No descriptor was allocated to any factor for determining safety level. The study also suggests recommendations for future planning concerning existing failures for designers. It was found that the safety level of the regional and local parks differ from each other.

Causes and consequences of injuries in children in Western Australia

Objective

To identify the common causes and consequences of pediatric injury-related admission to an Australian children’s hospital.

Methods

A retrospective study was conducted at a pediatric teaching hospital. Patients < 18 years of age hospitalized between March 1, 2007 and April 30, 2007 were included. Patient medical records were reviewed if an admission diagnosis was injury related. Data collected included date of birth, gender, date of admission, date of discharge, diagnosis, procedure, and causes and outcomes of the injury.

Results

A total of 184 patients were admitted as a result of injury during the study period. Of these, one neonate, six infants, 38 toddlers, 111 children, and 28 teenagers were included in this study. The most common cause of injury-related hospital admission was a fall (n = 109, 59%). Other causes of injury included crushing (8%, n = 15), the spilling of fluids (5.4%, n = 10), and bites (4.3%, n = 8). The most common consequence of an injury for children (43/111, 38.7%) and teenagers (12/28, 43%) was bone fracture. However, head injuries were the most common injury in toddlers (11/38, 29%), infants (5/6, 83.3%), and neonates (1/1, 100%). The radius and/or ulna (36/63, 57%) were the most common bones fractured. The majority (32/37, 86.5%) of patients who suffered head injuries were diagnosed as having a minor injury.

Conclusion

The main cause of injury-related admission to the hospital for children was a fall, with the most common consequences being fractures and head injuries.

Composite playground safety measure to correlate the rate of supracondylar humerus fractures with safety: an ecologic study

BACKGROUND

More than 200,000 children are injured at playgrounds in the United States each year. Our goal was to introduce a composite measure of playground safety and use this instrument to correlate the incidence of supracondylar humerus fractures with playground safety in an ecologic study design.

METHODS

We used a novel "overall-safety rating," defined as a composite of 3 previously validated instruments (National Program for Playground Safety School score, surface depth compliance, and the use zone compliance) to measure the overall safety of all playgrounds within a region. The regions were rated from most to least safe based on average playground safety as measured by this new method. The incidence of supracondylar fractures was calculated using Hasbro Children's Hospital Emergency Department data and state of Rhode Island Census data from 1998 to 2006. The incidence was then correlated with playground safety as defined by our composite measure.

RESULTS

Compared with the neighborhood deemed the safest, the least safe district had 4.7 times greater odds of supracondylar humerus fracture. Overall composite safety score of the district was linearly correlated with the injury rate observed in the population at risk (R=0.98; P=0.04).

CONCLUSIONS

Using our novel composite playground safety score, we found that the incidence of supracondylar humerus fractures was increased in districts with playgrounds with lower scores, suggesting that improvements in playground infrastructure may potentially reduce the incidence of supracondylar humerus fractures, and other injuries, in children.

Trauma prevention in children

Play and sports activities are important to the healthy development of children worldwide. Many accidents are the result of the normal desire of children for excitement and adventure. Injury prevention has been difficult to evaluate and manage because of many variables. The frequency of injuries can be reduced with parental input and adult supervision, as well as proper equipment design and installation, followed by regular inspection and maintenance. Current initiatives hold promise, especially with equipment designs and manufacture, but injuries continue to be a significant and costly health problem. By identifying where and how children are injured, recommendations can be made to increase the safety of play areas, gyms, and equipment.

The effect of safer play equipment on playground injury rates among school children

BACKGROUND

Changes to Canadian Standards Association (CSA) standards for playground equipment prompted the removal of hazardous equipment from 136 elementary schools in Toronto. We conducted a study to determine whether applying these new standards and replacing unsafe playground equipment with safe equipment reduced the number of school playground injuries.

METHODS

A total of 86 of the 136 schools with hazardous play equipment had the equipment removed and replaced with safer equipment within the study period (intervention schools). Playground injury rates before and after equipment replacement were compared in intervention schools. A database of incident reports from the Ontario School Board Insurance Exchange was used to identify injury events. There were 225 schools whose equipment did not require replacement (nonintervention schools); these schools served as a natural control group for background injury rates during the study period. Injury rates per 1000 students per month, relative risks (RRs) and 95% confidence intervals (CIs) were calculated, adjusting for clustering within schools.

RESULTS

The rate of injury in intervention schools decreased from 2.61 (95% CI 1.93-3.29) per 1000 students per month before unsafe equipment was removed to 1.68 (95% CI 1.31-2.05) after it was replaced (RR 0.70, 95% CI 0.62-0.78). This translated into 550 injuries avoided in the post-intervention period. In nonintervention schools, the rate of injury increased from 1.44 (95% CI 1.07-1.81) to 1.81 (95% CI 1.07-2.53) during the study period (RR 1.40, 95% CI 1.29-1.52).

INTERPRETATION

The CSA standards were an effective tool in identifying hazardous playground equipment. Removing and replacing unsafe equipment is an effective strategy for preventing playground injuries.

Injury and frequency of use of playground equipment in public schools and parks in Brisbane, Australia

OBJECTIVE

The purpose of this study was to determine the frequency of use of play equipment in public schools and parks in Brisbane, Australia, and to estimate an annual rate of injury per use of equipment, overall and for particular types of equipment.

METHODS

Injury data on all children injured from playground equipment and seeking medical attention at the emergency department of either of the two children's hospitals in the City of Brisbane were obtained for the years 1996 and 1997. Children were observed at play on five different pieces of play equipment in a random sample of 16 parks and 16 schools in the City of Brisbane. Children injured in the 16 parks and schools were counted, and rates of injury and use were calculated.

RESULTS

The ranked order for equipment use in the 16 schools was climbing equipment (3762 uses), horizontal ladders (2309 uses), and slides (856 uses). Each horizontal ladder was used 2.6 times more often than each piece of climbing equipment. Each horizontal ladder was used 7.8 times more than each piece of climbing equipment in the sample of public parks. Slides were used 4.6 times more than climbing equipment in parks and 1.2 times more in public schools. The annual injury rate for the 16 schools and 16 parks under observation was 0.59/100 000 and 0.26/100 000 uses of equipment, respectively.

CONCLUSIONS

This study shows that annual number of injuries per standardized number of uses could be used to determine the relative risk of particular pieces of playground equipment. The low overall rate of injuries/100 000 uses of equipment in this study suggests that the benefit of further reduction of injury in this community may be marginal and outweigh the economic costs in addition to reducing challenging play opportunities.

Injuries to preschool children and infection control practices in childcare programs

Injuries represent the leading cause of death for children aged 0 to 12 years, and exposure to blood or bodily fluids at the time of injury may pose a health and safety problem. More than 800,000 injuries were reported in 2000, and many occurred in childcare programs. This survey examined rate, type, and extent of injuries in centers and the infection control practices employed by staff. Participants included 131 children aged six weeks to seven years, enrolled in two childcare programs in an urban setting. Eight hundred ninety-seven injury reports with 1,023 (126 simultaneous) injuries were recorded over a one-year period. Results indicated the majority of injuries (39%) were for bites and 11% were self-inflicted. Injuries were classified as minor (99%) or moderate (1%) with 73% receiving first aid by staff. Bleeding from injuries was minimal in 14% of injuries, while no injuries reported moderate or severe bleeding. The rate of medically attended (first aid treatment) injury was 5.31 per 100,000 child hours. Injury rates decreased with age in the center (P = .001), were higher for males (P = .036), and occurred most frequently in the morning (P = .001). Age, gender, and time of the day were significant predictors of injuries in the multivariate model.

Playground injury prevention

Playground safety recently has received increasing attention from parents and municipalities. Orthopaedic surgeons treat a large number of the more than 350,000 injuries per year sustained on the play areas of this country's school, home, and community play areas. A parent brings a child to the playground for fun, healthy exercise, and imaginative play. Unfortunately, most parents may not be aware of recommended injury prevention methods. Data from the Consumer Product Safety Commission and other epidemiologic studies document frequency, identify at-risk activities and equipment, give direction for additional research, and guide regulations. It is appropriate for the medical community to lead in this safety effort and to contribute to additional research and advocacy efforts.

Trends and patterns of playground injuries in United States children and adolescents

OBJECTIVE

To determine the prevalence, trends, and severity of injuries attributable to playground falls relative to other common unintentional mechanisms that resulted in an emergency department (ED) visit in the United States.

DESIGN AND SETTING

Data from the emergency subset of the National Hospital Ambulatory Medical Care Survey collected from 1992 to 1997 for children <20 years.

METHODS

Injury rates and 95% confidence intervals (CIs) were estimated and injury severity scores were computed.

RESULTS

There were 920551 (95% CI: 540803 to 1300299) ED visits over the 6-year study period by children and adolescents that were attributable to falls from playground equipment. The annual incidence of visits for playground injuries did not significantly decrease over the course of the study (187000 to 98000, P =.053). Injury visits for playground falls were twice as prevalent as pedestrian mechanisms, but they were less prevalent than visits for motor vehicle-- and bicycle-related injuries. A larger proportion of playground falls resulted in "moderate-to-severe" injury than did bicycle or motor vehicle injuries. Children aged 5 to 9 years had the highest number of playground falls (P =.0014). Playground falls were most likely to occur at school compared to home, public, and other locations (P =.0016).

CONCLUSIONS

Playground injury emergency visits have not significantly declined and remain a common unintentional mechanism of injury. Injury visits for playground falls were proportionally more severe than injury visits attributable to other common unintentional mechanisms. Interventions targeting schools and 5- to 9-year-old children may have the greatest impact in reducing emergency visits for playground injuries.

Surface characteristics, equipment height, and the occurrence and severity of playground injuries

OBJECTIVES

To evaluate whether surface characteristics (absorption level (g-max), material) and the height of play equipment are related to the occurrence and severity of injuries from falls.

SETTING AND METHODS

During the summers of 1991 and 1995, conformity of play equipment to Canadian standards was assessed in a random sample (n = 102) of Montreal public playgrounds. Surface absorption (g-max) was tested using a Max Hic instrument and the height of equipment was measured. Concurrently, all injuries presenting at the emergency department of Montreal's two children's hospitals were recorded and parents were interviewed. Inspected equipment was implicated in 185 injuries. The g-max measurements (1995 only) were available for 110 of these playground accidents.

RESULTS

One third of falls (35 %) occurred on a surface exceeding 200 g and the risk of injury was three times greater than for g level lower than 150 (95% confidence interval (CI) 1.45 to 6.35). On surfaces having absorption levels between 150 g and 200 g, injuries were 1.8 times more likely (95% CI 0.91 to 3.57). Injuries were 2.56 times more likely to occur on equipment higher than 2 m compared with equipment lower than 1.5 m. Analysis of risk factors by severity of injury failed to show any positive relationships between the g-max or height and severity, whereas surface material was a good predictor of severity.

CONCLUSIONS

This study confirms the relationships between risk of injury, surface resilience, and height of equipment, as well as between type of material and severity of injury. Our data suggest that acceptable limits for surface resilience be set at less than 200 g, and perhaps even less than 150 g, and not exceed 2 m for equipment height. These findings reinforce the importance of installing recommended materials, such as sand, beneath play equipment.

Metal lawn and garden edging: the hidden knife?

OBJECTIVE

Lacerations account for many visits to the pediatric emergency department. We observed children presenting to local emergency departments in a large metropolitan area with lacerations incurred from metal lawn and garden edging, a landscaping tool. We sought to describe the severity of lacerations caused by metal edging, the characteristics of wound repair, and the need for subspecialty consultation.

DESIGN

A retrospective chart review including all pediatric patients (< 18 years) presenting with lacerations caused by metal lawn and garden edging from January 1995 to October 1997 was performed. Patients were seen at one of three emergency departments in Colorado.

RESULTS

One hundred twenty-six patients were enrolled (76% male, 24% female), with a median age of 9 years. The most frequent location of laceration was the foot (40%), followed by the knee (26%). The median length of laceration was 3 cm (range 1-22 cm). Sixteen patients (13%) received either intravenous or oral antibiotics, and six patients (5%) received orthopedic evaluation.

CONCLUSIONS

Metal lawn and garden edging in landscaped neighborhoods presents a previously undescribed laceration danger to children. Some lacerations sustained from the metal lawn edging are extensive, receiving either multiple layer closure and/or the need for subspecialty consultation.

Risk factors for severe injuries associated with falls from playground equipment

A case control study design was used to determine the risk factors for severe injuries associated with falls from playground equipment. Children presenting to the Hospital for Sick Children in Toronto because of falls from playground equipment (1995-1996) were identified through daily review of admissions and emergency department visits. Cases were defined as children with a severe injury (AIS > or = 2), whereas, controls were children with a minor injury (AIS < 2). Data on age, sex, socioeconomic status, prior experience on the equipment, previous playground injury, type of equipment, height of fall, undersurface, nature of injury, body part involved, and disposition were collected via telephone interview, field trip measurement, and mailed questionnaire. A total of 126 children were studied--67 cases and 59 controls. There were no differences between the two groups on age, sex, socioeconomic status, prior exposure to the equipment, or previous playground injury. Extremity fractures predominated in the case group, while, facial lacerations predominated in the control group. The median height of fall for cases was 199 cm, compared with 160 cm for controls (P = 0.021). Cases were also more likely to have fallen from a height of > 150 cm (73%), compared with controls (54%), P = 0.027. The majority of cases (82%) and controls (86%) fell onto an impact absorbing undersurface (P = 0.540). The median depth of impact absorbing undersurface, however, for both case and control injuries was 3 cm--well below the recommended safety standards. Height of fall was an important risk factor for severe injury associated with falls from playground equipment. Above 150 cm, the risk of severe injury was increased 2-fold.

Children at play: the death and injury pattern in New South Wales, Australia, July 1990-June 1994

OBJECTIVES

To describe and to understand the pattern of play-related deaths and injury (excluding organized sports) among children in New South Wales (NSW), Australia.

METHODOLOGY

This study utilized a state-wide prospective surveillance data collection of paediatric traumatic deaths and injuries at the Royal Alexandra Hospital for Children. Deaths and injury cases were selected from the NSW Trauma Death Registry and Childsafe NSW database. Information including basic demographics, the surrounding circumstances of death and injury incidents, and the required treatment was collected.

RESULTS

There were 30 play-related deaths and 92 drownings over the 4-year period. The male to female ratio was about 2:1. Excluding drowning, which has been reported elsewhere, and sports, the leading causes of play-related deaths were burns (eight) and asphyxiation (eight). An average of 6444 presentations to the emergency departments per year were recorded with sex ratio and age distribution pattern similar to the deaths. The home was the most common place (55.5%) of play-related injury, specifically the living and sleeping area. Falls, both under and above 1 metre, were the most common causes of injury (50.9%). The leading mechanism was cuts and lacerations (21.2%). Nearly one-third (32.7%) of all injuries were to the head, with face, cheek, forehead and scalp as the most common injured body part. Significant associations between place of injury, injured body parts and age were observed.

CONCLUSIONS

Play-related injury is common among children, and in some cases causes severe injury and death. To tackle the problem of play-related deaths and injuries, a holistic approach is suggested. This includes the provision of a safe environment, supervision by parents, education of children and detailed data collection.

An intervention to reduce playground equipment hazards

OBJECTIVES

A community intervention trial was carried out to evaluate the relative effectiveness of two methods of reducing playground hazards in schools. The study hypotheses were: (1) a health promotion programme addressing barriers to implementing the New Zealand Playground Safety Standard will reduce playground hazards and (2) the intervention programme will be more successful than providing information alone.

METHODS

Twenty four schools in Wellington, New Zealand were randomly allocated into two groups of 12 and their playgrounds audited for hazards. After the audit, the intervention group received a health promotion programme consisting of information about the hazards, an engineer's report, regular contact and encouragement to act on the report, and assistance in obtaining funding. The control group only received information about hazards in their playground.

RESULTS

After 19 months, there was a significant fall in hazards in the intervention schools compared with the control schools (Mann-Whitney U test, p = 0.027). No intervention schools had increased hazards and eight out of 12 had reduced them by at least three. In contrast, only two of the control schools had reduced their hazards by this amount, with three others increasing their hazards in that time.

CONCLUSIONS

It is concluded that working intensively with schools to overcome barriers to upgrading playground equipment can lead to a reduction in hazards, and that this form of intensive intervention is more effective than providing information alone.

Monkeybar injuries: complications of play

BACKGROUND

Playground equipment resulted in >200 000 injuries from 1990 to 1994, according to the Consumer Product Safety Commission; 88% were attributable to climbers (monkeybars/jungle gyms [MB/JGs]), swings, and slides. Equipment-specific injury requiring emergency department (ED) evaluation has not been reported previously.

OBJECTIVE

To describe the spectrum of significant MB/JG-related injuries.

METHODS

A 2-year retrospective chart review was performed using the computerized charting system at a large urban Children's Hospital/Regional Pediatric Trauma Center with 50 000 ED visits per year. A telephone survey also was conducted after the chart review to obtain additional information concerning the injury location, the surface type below the equipment, and the presence of adult supervision.

RESULTS

A total of 204 patients were identified. Mean age was 6.2 years (range, 20 months to 12 years); 114 (56%) were male. A seasonal variation was noted with June to August accounting for 43% of visits. Injuries included fractures in 124 (61%), contusions in 20 (10%), neck and back strains in 17 (8%), lacerations in 16 (8%), closed head injuries in 10 (5%), abdominal trauma in 5 (3%), genitourinary injuries in 5 (3%), and miscellaneous injuries in the remainder. Among fractures, 90% were fractures of the upper extremity; 48 (40%) were supracondylar fractures. One child sustained a C7 compression fracture. Abdominal injuries included 1 child who sustained a splenic laceration. All genitourinary injuries (2 vaginal hematomas, 1 vaginal contusion, 1 penile laceration, and 1 urethral injury) were from straddle-type injuries. Fifty-one (25%) patients were admitted to the hospital. Of these, 47 (92%) required an operative procedure (orthopedic reduction or vaginal examination under anesthesia). Analysis of the telephone data revealed that the surface did not influence the injury type. Of the 79 fractures, 30 occurred on "soft surfaces." Injury type was associated significantly with chronologic age. Younger children (1 to 4 years of age) sustained more long-bone fractures than did older children. The presence of adult (at least 18 years of age) supervision, did not influence the occurrence of fractures.

CONCLUSIONS

These data suggest that 1) a significant proportion (25%) of MB/JG-related injuries that are evaluated in the ED require hospitalization; 2) most of the injuries resulting in admission will require operative intervention (92%); 3) the surface below the equipment has no influence on the type or severity of the injury; 4) younger children are more likely to sustain long-bone fractures than are older children; and 5) adult supervision does not influence the injury pattern. These data identify the need for additional investigation of means of making MB/JGs safer for child use.

A case-control study of risk factors for playground injuries among children in Kingston and area

OBJECTIVE

To determine the risk for injury associated with environmental hazards in public playgrounds.

SETTING

One hundred and seventeen playgrounds operated by municipalities or school boards in and around Kingston, Ontario, Canada.

METHODS

A regional surveillance database was used to identify children presenting to emergency departments who were injured on public playgrounds; each case was individually matched (by sex, age, and month of occurrence) with two controls--one non-playground injury control, and one child seen for non-injury emergency medical care. Exposure data were obtained from an audit of playgrounds conducted using Canadian and US safety guidelines. Exposure variables included the nature of playground hazards, number of hazards, frequency of play, and total family income. No difference in odds ratios (ORs) were found using the two sets of controls, which were therefore combined for subsequent analysis.

RESULTS

Multivariate analysis showed strong associations between injuries and the use of inappropriate surface materials under and around equipment (OR 21.0, 95% confidence interval (CI) 3.4 to 128.1), appropriate materials with insufficient depth (OR 18.2, 95% CI 3.3 to 99.9), and inadequate handrails or guardrails (OR 6.7, 95% CI 2.6 to 17.5).

CONCLUSION

This study confirms the validity of guidelines for playground safety relating to the type and depth of surface materials and the provision of handrails and guardrails. Compliance with these guidelines is an important means of preventing injury in childhood.

Safe Child Penarth: experience with a Safe Community strategy for preventing injuries to children

OBJECTIVES

To evaluate the process of establishing a Safe Community project for children.

DESIGN

A descriptive study.

SETTING

Penarth, a town (population 20,430) Vale of Glamorgan, South Wales.

SUBJECTS

3943 children and their families in Penarth.

MAIN OUTCOME MEASURES

Whether the 12 criteria for a Safe Community project (World Health Organisation) were met. Implementation of the safety agenda set by the community.

RESULTS

Safe Child Penarth met 10 of the 12 criteria for the Safe Community network. All the items on the agenda were introduced in the initial two years of the project. There were difficulties, however, achieving sustained community ownership of the project.

CONCLUSIONS

The Safe Community concept stimulated work to improve child safety in Penarth. Community safety initiatives should involve all local agencies to identify the problems and work with the community to set and meet the safety agenda. Partnership with the local authority is valuable to improve the safety of the environment. The experience generated from Safe Child Penarth has been used to develop a county wide, all age community safety project.

Childhood accidents: epidemiology, trends, and prevention

Accidents are the most common cause of death in children over one year of age. Prevention remains a high priority. We have reviewed the current epidemiology of childhood accidents and their prevention, and made recommendations for the future. In 1992, 559 children died in United Kingdom as a result of an accidents--240 from road traffic accidents and 100 from burns and scalds. Every year 50 children drown. Accidents cause significant disability to children. Many children, up to one in four of the population in urban areas, attend accident and emergency departments, and 5-10% of these are admitted to hospital. Accident risk factors include low social class, psychosocial stress, an unsafe environment, and child developmental disorders. Research has shown that prevention is best achieved by making the child's environment safer, often through legislation. Insufficient resources have been put into both research into childhood injuries and preventive work in communities. Collaboration between health authorities, NHS trusts, local authorities and community networks is vital if success is to be achieved. A national safety agenda for children would focus the attention that this problem deserves.

Safety of surfaces and equipment for children in playgrounds

BACKGROUND

The safety of playgrounds is important to protect children from injury, but studies are mostly done mainly under laboratory conditions without epidemiological data. We investigated the safety of different playground surfaces, and types and heights of equipment in public playgrounds in the City of Cardiff, UK.

METHODS

We did a correlational study of 330 children aged between 0 and 14 years. All children were hurt when playing in playgrounds in Cardiff and presented to the Accident and Emergency Department in Cardiff Royal Infirmary during summer (April to September) 1992 and 1993, and the whole of 1994. We studied the children's hospital records to establish the type of injury and interviewed their parents to find out the playground and type of equipment involved. The main outcome measures were the number of children injured whilst playing, and injury rates per observed number of children on different surfaces, types, and heights of equipment.

FINDINGS

Children sustained significantly more injuries in playgrounds with concrete surfaces than in those with bark or rubberised surfaces (p < 0.001). Playgrounds with rubber surfaces had the lowest rate of injury, with a risk half that of bark and a fifth of that of concrete. Bark surfaces were not significantly more protective against arm fractures than concrete. Most injuries were equipment related. Injury risk due to falls from monkey bars (suspended parallel bars or rings between which children swing) was twice that for climbing-frames and seven times that for swings or slides. The height of the equipment correlated significantly with the number of fractures (p = 0.005) from falls.

INTERPRETATION

Rubber or bark surfacing is associated with a low rate of injuries and we support their use in all public playgrounds. Bark alone is insufficient, however, to prevent all injuries, particularly arm fractures. Rubberised impact-absorbing surfaces are safer than bark. We believe that playing on monkeys bars increases the risk of injury in playgrounds and that they should generally not be installed. Safety standards should be based on physical and epidemiological data. Our data suggest that the proposed raising of the maximum fall height from 2.5 m to 3.0 m in Europe is worrying.

A nursing intervention to ensure a safe playground environment

Unintentional injuries sustained on school playgrounds are a continual problem not only for children but also for the school nurses who are concerned with their safety. A group of school nurses organized by the local health department's pediatric nurse practitioner responded proactively to this problem by enlisting both school officials and students to accept joint responsibility for a safe play environment. The school nurses assisted the staff in providing a safe play environment and encouraged the students to behave in a safe and acceptable manner on the playground. The nurses developed (a) a Playground Safety Assessment Guide for the school staff to establish and maintain a safe play environment, (b) an in-service session for playground monitors to learn how to supervise children at recess, and (c) a student-oriented program for the children to improve behavior on the playground based on a program conceived by Utah State University (Daug & Fukui, 1988). School nurses and pediatric nurse practitioners can use this program as a model for other schools to improve the physical play environment and behavior of the children at recess.

Height and surfacing as risk factors for injury in falls from playground equipment: a case-control study

OBJECTIVES

Despite the widespread promotion of safety standards no epidemiological studies have adequately evaluated their effectiveness in preventing injury in falls from playground equipment. This study evaluated the effectiveness of the height and surfacing requirements of the New Zealand standard for playgrounds and playground equipment.

SETTING

Early childhood education centres and schools in two major cities in the South Island of New Zealand.

METHODS

Data were collected on 300 children aged 14 years or less who had fallen from playground equipment. Of these, 110 (cases) had sustained injury and received medical attention, while 190 (controls) had not sustained injury requiring medical attention.

RESULTS

Logistic regression models fitted to the data indicated that the risk of injury being sustained in a fall was increased if the equipment failed to comply with the maximum fall height (odds ratio (OR) = 3.0; 95% confidence interval (CI) 0.7 to 13.1), surfacing (OR = 2.3; 95% CI 1.0 to 5.0), or safe fall height (OR = 2.1; 95% CI 1.1 to 4.0) requirements. Falls from heights in excess of 1.5 metres increased the risk of injury 4.1 times that of falls from 1.5 metres or less and it was estimated that a 45% reduction in children attending emergency departments could be achieved if the maximum fall height was lowered to 1.5 metres.

CONCLUSIONS

Although the height and surfacing requirements of the New Zealand standard are effective in preventing injury in falls from playground equipment, consideration should be given to lowering the maximum permissible fall height to 1.5 metres.
