Safety seat and seat belt use among child motor vehicle occupants, Cluj-Napoca, Romania

BackgroundUse of seat belts and car seats for children are among the most effective interventions to reduce injury severity when a crash occurs. The use should be enforced in order to have an increase in wearing these restraints. Romania has the lowest rate of using seatbelts in the backseat, 16%. The purpose of the study is to describe the use of child safety restraints and compare it with existing standards of good practice.MethodsAn observational study on child safety restraint was conducted in Cluj-Napoca, Romania, between 2013 and 2014. Observational sites included 38 schools and kindergartens and three commercial areas, where drivers (n=768) and child passengers (n=892) were observed. Observations were conducted as vehicles parked or pulled to a stop and were followed by driver surveys on knowledge and attitudes towards restraint legislation and child safety behaviour as car occupants.ResultsThe proportion of observed child motor vehicle occupants wearing some type of restraint was 67.4% (n=601). The majority of children (82.6%) were in the back seat, and 14.2% of infants were in a rear-facing child seat. The proportion of restrained children declined with age, with children 5 years old or younger being almost five times more likely to be properly restrained (OR 4.87, 95% CI 2.93 to 8.07) when compared with older children.ConclusionsAlthough minimum legal requirements of child motor vehicle occupant safety were in place in Romania at the time of the study, the rates of using children restraints was low compared with other middle-income and high-income countries.

Ambulance Crash Characteristics in the US Defined by the Popular Press: A Retrospective Analysis

Ambulance crashes are a significant risk to prehospital care providers, the patients they are carrying, persons in other vehicles, and pedestrians. No uniform national transportation or medical database captures all ambulance crashes in the United States. A website captures many significant ambulance crashes by collecting reports in the popular media (the website is mentioned in the introduction). This report summaries findings from ambulance crashes for the time period of May 1, 2007 to April 30, 2009. Of the 466 crashes examined, 358 resulted in injuries to prehospital personnel, other vehicle occupants, patients being transported in the ambulance, or pedestrians. A total of 982 persons were injured as a result of ambulance crashes during the time period. Prehospital personnel were the most likely to be injured. Provider safety can and should be improved by ambulance vehicle redesign and the development of improved occupant safety restraints. Seventy-nine (79) crashes resulted in fatalities to some member of the same groups listed above. A total of 99 persons were killed in ambulance crashes during the time period. Persons in other vehicles involved in collisions with ambulances were the most likely to die as a result of crashes. In the urban environment, intersections are a particularly dangerous place for ambulances.

Tilt Determination in MEMS Inertial Vestibular Prosthesis

Background: There is a clear need for a prosthesis that improves postural stability in the balance impaired. Such a device would be used as a temporary aid during recovery from ablative inner-ear surgery, a postural monitor during rehabilitation (for example, hip surgery), and as a permanent prosthesis for those elderly prone to falls. Method of approach: Recently developed, small instruments have enabled wearable prostheses to augment or replace vestibular functions. The current prosthesis communicates by vibrators mounted on the subject’s trunk. In this paper we emphasize the unique algorithms that enable tilt indication with modestly performing micromachined gyroscopes and accelerometers. Results: For large angles and multiple axes, gyro drift and unwanted lateral accelerations are successfully rejected. In single-axis tests, the most dramatic results were obtained in standard operating tests where balance-impaired subjects were deprived of vision and proprioceptive inputs. Balance-impaired subjects who fell (into safety restraints) when not aided were able to stand with the prosthesis. Initial multiaxis tests with healthy subjects have shown that sway is reduced in both forward-back and sideward directions. Conclusions: Positive results in initial testing and a sound theoretical basis for the hardware warrant continued development and testing, which is being conducted at three sites.

Recognizing the Common Problem of Child Automobile Restraint Misuse

The effectiveness of safety restraints in protecting children from motor vehicle injuries has been well documented,1 prompting all states to require that child passengers ride in appropriate restraints.2 Although the prevalence of child restraint device use has increased following the passage of child restraint device laws, many drivers use restraints incorrectly on their child passengers. For example, in a recent study of child restraint device use, we reported that, although 75% of children were riding in restraints on seat belts, 62.9% of those children were incorrectly restrained.3 In a 1984 study, Cynecki and Goryl4 reported a similar misuse rate of 64.6%.
