21 34 46 Inevitable FX = Fracture; PE = Pulmonary Embolism; BCP = Bronchopneumonia; MC. = Myocardial Contusion; HT = Head Trauma Discussion In relation to the patients’ age, it was observed that the data found are in agreement with national and international literature [14–16]. When

we checked the behaviour of the age variable with respect #SAHA HDAC purchase randurls[1|1|,|CHEM1|]# to study groups, statistical differences were found, with SAMU showing a higher mean age than the individuals attended by CB. There is very little literature focusing on this type of analysis. Carret et al [17], in a systematic review, sought to measure the prevalence of, and factors associated with the inappropriate use of emergency services. They found, among other factors, the Bleomycin order difficulty of access to medical first aid, and concluded that first aid should be carried out in a qualified way. In fact, in the present

study, the vast majority of patients in both study groups show trauma severity of low complexity, which may have been resolved by the first aid units (discharge from emergency units stands at over 81.7% of users). Deslandes et al [18] report that within a community, there is a local culture that seeks immediate attention and resolution to its ailments, associated with its own interpretation of what constitutes an emergency situation, leading to the use of all the available emergency care equipment and generating a burden of care in emergency care centers. In the city of Rio de Janeiro, O’Dwyer et al [19] analyzed the quality of care in emergency services and found misuse of these services in 65% of cases. It may be assumed that this situation also occurs in pre-hospital services, mainly due to the lack of medical regulation. The literature is small and incipient when it comes to reporting the severity of users’

users. Marques et al [20] found, in the city of Porto Alegre (RS-Brazil), amongst patients treated by SAMU, an 8.2% utilization rate of the USA vehicle. In this study, the usage rate of the USA vehicle was 6.7% for the general study population study, and 10.8% for Buspirone HCl the SAMU users group. Nardoto [21], studying the victims attended by the air ambulance pre-hospital service, found a trauma severity score of 18.4%, based on the Glasgow Coma Scale, alone, showing that even for a vehicle that specializes in immediate care of critically ill patients, the rate of severity is relatively low. Regarding the causes of injury, among those related to road traffic accidents, motorcycle accidents were the most prevalent (32.8%), followed by automobile accidents (10.3%). Gawryszewski et al [22], studying call outs to road traffic accidents in the State of São Paulo, observed that motorcycle accidents represented 29.8% of cases, followed by automobile accidents (25.7%) and then pedestrians being hit by vehicles (24.1%). In our study these figures were 32.8%, 10.3% and 6.3% respectively.
