How the science of injury prevention contributes to advancing home fire safety in the USA: successes and opportunities.

Inj Prev 2018 06 26;24(Suppl 1):i7-i13. Epub 2018 Feb 26.

Center for Injury Research and Policy, Nationwide Children's Hospital, Ohio State University College of Medicine, Columbus, Ohio, USA.

Background: In the decades since the landmark report-America Burning-was published in 1973, the number of home fire deaths has shrunk from >5500 per year to 2650 in 2015. This paper: (1) describes how science and practice in injury prevention and fire and life safety contributed to successful interventions, and (2) identifies emerging strategies and future opportunities to prevent home fire-related deaths.

Methods: The aims are addressed through the lens of population health research, with a focus on the work of selected Centers for Disease Control and Prevention-funded Injury Control Research Centers. Results are organised using the Haddon Matrix and an ecological model.

Results: We found evidence to support interventions that address all components of both the matrix and the model, including: reduced ignition propensity cigarettes, stop smoking campaigns, housing codes, residential sprinkler systems, smoke alarms, community risk reduction, school-based educational programmes, and fire and burn response systems. Future reductions are likely to come from enhancing residential sprinkler and smoke alarm technology, and increasing their utilisation; expanding the use of community risk reduction methods; and implementing new technological solutions. Despite the successes, substantial disparities in home fire death rates remain, reflecting underlying social determinants of health.

Conclusion: Most of the evidence-supported interventions were focused on changing the policy and community environments to prevent home fires and reduce injury when a fire occurs. Future prevention efforts should give high priority to addressing the continued disparities in home fire deaths.

Pediatric Diaphyseal Femur Fractures: Submuscular Plating Compared With Intramedullary Nailing.

Orthopedics 2016 Nov 27;39(6):353-358. Epub 2016 Jul 27.

This study compared the radiographic and clinical outcomes of pediatric diaphyseal femur fractures treated by submuscular plating, flexible retrograde intramedullary nailing, or rigid antegrade intramedullary nailing with a trochanteric entry point in skeletally immature patients who were 8 years and older. A retrospective review was conducted of skeletally immature patients 8 years and older who were treated for femur fracture with submuscular plating, flexible intramedullary nailing, or rigid intramedullary nailing from 2001 to 2014 with a minimum 12-week follow-up. Treatment outcomes were compared for statistical significance, including time to union, malunion, nonunion, heterotopic ossification, avascular necrosis, time to full weight bearing, limb length discrepancy, residual limp, painful hardware, and infection. The study identified 198 femur fractures in 196 patients (mean age, 11.9 years). Each femur fracture was treated with submuscular plating (35), flexible intramedullary nailing (61), or rigid intramedullary nailing (102). Mean follow-up across the cohort was 48 weeks, ranging from 12 to 225 weeks. Flexible nailing was associated with an increased incidence of malunion (P<.0001) and hardware irritation (P=.0204) and longer time to full weight bearing (P=.0018). Rigid nailing was associated with an increased incidence of limp at 12-week followup (P=.0412). Additionally, 23.5% of patients who were treated with rigid nailing had heterotopic ossification. Of all surgical methods, submuscular plating allowed for the most rapid return to full weight bearing (mean, 7 weeks) and offered the fastest healing rate (mean, 6 weeks). Submuscular plating resulted in faster times to union and full weight bearing, with minimal complication rates. Rigid intramedullary nailing with trochanteric entry resulted in a lower incidence of malunion and hardware-related complications; however, these patients had an increased incidence of heterotopic ossification and residual limp postoperatively. Flexible retrograde intramedullary nailing resulted in the highest rates of malunion and hardware irritation and the longest time to full weight bearing. [Orthopedics. 2016; 39(6):353-358.].
