Evaluation of care for traffic accidents victims made by on duty emergency physicians and surgeons in the emergency room

Objective: to evaluate the care for victims of traffic accidents by on call emergency physicians and/or surgeons in the emergency room. Methods: we conducted a retrospective, descriptive and exploratory study on the care for traffic accidents victims in the urban area of Maringá-PR, between July 2013 and July 2014 in reference hospitals. We assessed demographics and vocational training through a questionnaire sent to the attending physicians. Results: of the 688 records evaluated, 99% of patients had a prehospital Revised Trauma Score of 12. Statistical analysis showed that in the cases conducted by the emergency physicians (n =187), the recording of the Glasgow Coma Scale and the performance of surgical procedures were less common, whereas the recording of blood pressure values was performed in greater numbers when compared with cases led by surgeons (n=501). There was a statistically significant relationship (p<0.01) between the length of hospital stay and surgical specialty, with a greater chance (crude OR=28) in the period from one to six hours for the group treated by emergency doctors. Most physicians participating in the study were young, with emergency room time of up to one to two years, and with ATLS training. Among those who had attended the ATLS course, 60% did so in the last four years. Surgeons performed 73% of hospital treatments. Conclusion: in the care of traffic victims with minor injuries, the Glasgow Coma Scale, the blood pressure levels, the type of treatment in the emergency room and hospital stay had different approaches between emergency physicians and surgeons.


INTRODUCTION
I n recent years, Trauma has become one of the biggest public health problems 1 . In cases of traffic accidents (TA), thousands of lives are compromised each year, making constant the need for discussion, prevention planning and treatment of these victims 2, 3 .
In pre-hospital care provided by the Emergency Trauma Care Integrated Service (SIATE) of the Fire Department, triage and classification of victims are carried out according to the degree of severity, followed by primary care for stabilization of the urgency or emergency condition and later referral to a more complex service for the continuity of treatment 4 .
In Brazil, not all hospital services have qualified professionals for the care of multiple trauma. Any doctor who has professional license can act as an emergency physician 5 . The Resolution 2077/14 of the Federal Medicine Council (CFM) deals with the regulation of the Emergency Hospital, as well as with the design of the medical team and the work system. Its Art. 3 rd defines the obligation of care be performed by a doctor, though with no reference as to specialty 6 . In practice, it is observed that the "emergency room" doctor is specializes in internal medicine or general surgery, and should have appropriate skills and knowledge to work in the emergency room. However, the CFM Resolution n o 2149/2016 of July 22, 2016, approves the recognition of Emergency Medicine as a medical specialty, and Emergency Medicine as a Medical Practice Area 6 . These new well trained specialists may make a difference with appropriate and safe decisions when acting in emergency settings 7 .
The difference of the specialized training and personality between the internal medicine physician and the surgeon is historical. Bellodi 8 noted that even today, the stereotypes of these doctors are equivalent, despite all the changes over time. To clinicians, formerly physicists, the appreciation of the mind, and to surgeons, the barbers, the risky procedures 8,9 . In another study with a group of Brazilian residents, the same author identified, amongst other variables, personality traits, the clinicians being quieter, detaildriven and more interested in interpersonal contact, while the surgeons are faster, more impulsive and more aggressive 10 .
It is possible that this type of aggressive and impulsive personality is a decisive factor in choosing training courses that enable the surgeon to care for polytrauma patients. This formation goal tends to make this professional the most suitable and most qualified for this type of service, differentiating him/ her from those with other interests.
Considering the studies showing different personality characteristics between clinicians and surgeon as a factor for specific training, it is fair to raise the following issue: "Is there a difference in trauma care provided by the emergency physician and the surgeon?". So far, there are no references in the literature comparing the polytrauma patient approach with the kind of specialty of the emergency room doctor.
The objectives of this study were to evaluate the care of victims of traffic accidents by emergency physicians and / or surgeons in the emergency room and to identify the emergency training of such doctors.

METHODS
We conducted an observational, documental, retrospective, descriptive and exploratory study, with traffic accident (TA) victims in urban areas, over 18 years of age, of both gender, attended by the prehospital rescue team -SIATE -in Maringa, PR, and sent to reference hospitals in the period from July 2013 to July 2014.
We obtained data from the site www. bombeiroscascavel.com.br, collecting the records made by Maringa Fire Department V Division, containing the name, day, time and type of event and the destination hospital. With this list, we then obtained the hospital records of patients and Rescue Attendance Reports (RAR).
The variables analyzed in this study were: type of medical specialty of the professional who attended the victim, recording of Glasgow Coma Scale (GCS) and of levels of Systemic Blood Pressure (SBP), procedures carried out by the professional and hospital stay.
As non-surgical procedures, we considered analgesia, clinical observation, neurological observation and sole evaluation; and as surgical procedures, analgesia + dressing, analgesia + immobilization, dressing, immobilization and suture.
We applied a questionnaire to doctors working at the emergency rooms to characterize the professionals as for demographic variables, professional training and difficulties in trauma patient care.
We ordered data in spreadsheets (Microsoft Excel for Mac 2011 Version 14.6.0) and analyzed them in a descriptive way through absolute numbers and percentages. We applied the chi-square test, uni and multivariate analysis with the software SAS 9.4, considering p≤0.05 as significant.
This study was approved by the Standing Committee on Human Research of the State University of Maringa (COPEP-UEM), opinion N o 37686114.8.0000.0.

RESULTS
During the study period, 45 physicians (17 clinicians and 28 surgeons) were responsible for the care of 688 TA victims (177 attendances by emergency physicians and 501 by surgeons).
According to univariate analysis, there were statistically significant differences between variables related to medical specialty. The results are shown in Table 1.
GCS values were recorded in 345 evaluations made by surgeons and in 56 cases treated by clinicians. In 287 records, GCS recording was absent. The chance of a clinician not recording the GCS was 5.2 times higher than the surgeon's.
SBP values were recorded in 137 evaluations made by surgeons and in 129 by clinicians, lacking in 422 charts. The chance of a clinician recording SBP was six times higher than the surgeon's.
Hospital stay greater than six hours occurred in 10% (n=69) of treated cases; 99% of these visits were performed by surgeons. The chance of a clinician discharging a patient before six hours of observation was 28 times greater than the surgeon's.
Regarding the type of treatment provided in the emergency room, in 75% (n=515) of cases "nonsurgical" procedures were performed. The chance of a clinician performing a non-surgical procedure was 1.7 times greater than the surgeon's.
We also applied multivariate analysis and found a statistical correlation between variables, whose results are shown in Table 2.
As for the length of stay and type of treatment, we observed that these were not associated factors (Table 3).
Only 40% (n=18) of physicians responded to the questionnaire, identifying some features shown in Table 4. The profile found in this study were of young doctors, mostly male and Surgeons, 61% with ER time less than four years and with ATLS training. Of these, 60% had taken the course less than four years before.

DISCUSSION
There is no legal requirement in Brazil for the doctor attending the emergency room to be from a clinical or surgical specialty. In this sample, there was a contingent of surgeons greater than clinicians.
In the 688 patient records analyzed, we observed that surgeons have made 501 evaluations and proportionately more surgical procedures than clinicians have. This fact could be justified by the victim having lesions that justify the procedure or by the greater predisposition toward this conduct by the characteristics of the surgeon, such as impulsiveness, quick thinking and aggressiveness in conducts 11 . Surgeons tend to be more practical, objective and like manual activities, often with faster and more concrete results 10 .
From a clinical point of view, the GCS score is an important neurological parameter and practically a synonym of gravity in head trauma (TBI). Scores between 3 and 8 are classified as severe trauma, between 9 and 12 as moderate and between 13 to 15 as mild 11 .
In a study of patients rescued by emergency mobile care service, Souza 12 reported that despite its importance, GCS was neglected many times, reporting abstention to record this value in 3.2% of cases. Ribeiro 13 identified charts without its records in 897 cases (97% of total) when filled by nurses prehospital, though with no references to notes in hospital care.
In this study, surgeons recorded GCS values in patients' charts at hospital admission more frequently than clinicians did (69% versus 30%, respectively). The vast majority of victims assisted (400 -58%) had scores between 13 and 15, and only one case presented score of 3. In 42% (n=287) this record was missing, and in some reviewed charts there was a description by the doctor that the victim was conscious, oriented and without motor deficits, inferring a high value for GCS; however, having not been registered, we did not consider it as recorded. This condition could explain the 42% of absence of GCS records in this sample.
In contrast, in cases reported in medical records (n=401), 86% were by surgeons, while only 14% by emergency physicians. The ATLS advocates the use of the GCS as an objective clinical measure of TBI severity, becoming routine to the doctor in polytrauma care, even in those patients without TBI 10 . This finding is important for the proper evaluation of trauma patients in view of the possibility of unnoticed injuries evolving to a neurosurgical emergency 14 .
Alavarce et al. 15 found that the SBP measure, besides being simple and easy to execute, should be carried out in all health care evaluations, independently of the attending physician specialty. In this study, we observed that surgeons recorded SBP values at hospital admission fewer times than clinicians did (27% versus 69%). A previous study found SBP recording in 85.3% of cases evaluated, differing from the latter because only 39% (n=266) of cases were recorded at admission, however, according to pre-hospital care data, SBP was recorded in 97% of case 16 .
SBP levels are an important physiological parameter in the evaluation of polytrauma patients, depending on the types of injuries found, translating volume loss (bleeding). Although not reflecting the actual state of tissue perfusion, its systematic measurement is advocated 17 . The estimated blood loss based on the initial condition of patients with multisystem trauma can be classified into classes (I, II, III and IV). Each has signs and symptoms according to the degree of volume loss. Classes I and II comprise an approximate blood loss of up to 15% (volume = 750ml) and between 15 and 20% (volume = 750 to 1500ml), respectively. On physical examination, one does not observe a drop in SBP levels in these two classes. This fall will be identified in shock, i.e., classes III and IV 11,18 .
In this study, most patients were victims of minor injuries and t-RTS 12 (corrected RTS 7.8408), with no evidence of hemorrhagic shock (mean systolic SBP 127mmHg), both in the prehospital assessment and at arrival at the emergency room. This could justify the lack of importance given by the surgeon to the measurement of blood pressure at that time and consequently to its recording.
Regarding the length of stay, we found that 621 patients (90.3%) remained for a time shorter or equal to six hours, and the majority (n=435) was attended by surgeons. We observed a greater chance of an emergency physician releasing the patient before six hours of observation. The relevance of this finding (OR=28) did not translate into better type of service or professional negligence. The result in question might be justified by the clinical picture and type of injury presented by the patient (t-RTS 12 and CODE 1 SIATE) opposing the medical specialty.
Vieira et al. 19 , in a study conducted in Sergipe, showed that 76% of victims treated had length of stay of up to 12 hours. In another study conducted in Ribeirão Preto, Coelho et al. 20 reported that 39.8% of patients remained for less than six hours and 27.4%, between 24 and 30 hours, with no mention to the type of specialty.
Statistical analysis showed that there was an association between length of stay and surgical specialty (Tables 1 and 2). However, when related to the type of treatment, there was no statistical association, that is, the chance of an emergency physician performing a non-surgical procedure in hospital stays shorter than or equal to six hours was similar to a surgeon's ( Table 3). Only 18% of care provided by clinicians needed surgical treatment in the emergency room, while for surgeons that number was 28%, which raised the suspicion of different complexity and time of stay, corroborating th significant finding (OR 28) mentioned above.
The results of the questionnaire applied to attending physicians (Table 3) showed that 89% of respondents were male, aged between 25 and 60 years and had surgical specialty. Most (50%) had time of ER over three years, and 39% of respondents had had ATLS training less than one year before.
Campos and Senger 21 reported that 31.7% of graduates worked in emergency services independently of being enrolled or not in some medical residency program. The easy insertion in these services pointed out the importance of proper training for care in this type of situation. Hamamoto 22 and Pego-Fernandes 23 reported the unpreparedness of recent graduates and the disorganization of the health care system, which hampers emergency care in public hospitals.
Still on ATLS, 81% of surgeons attended this training, while for the emergency physicians this percentage was 50%. This result suggests the initial hypothesis of this work, that surgeons are more interested in training for trauma care due to their training background and personality. Brito et al. 24 stated that training is of utmost importance for the improvement of professional performance, both individually and as a team, which corroborates the pressing need of the professional, regardless of specialty, to train in the respective field, besides making the professional feel more secure and able to provide adequate care 25 .
For 13 (72%) physicians, technical training was considered sufficient, and 89% reported feeling safe in the diagnosis and treatment of multiple trauma victims. However, 89% of respondents said trauma care requires specialized training. This need of respondents goes against the principle of the impact of ATLS training for trauma care, which says that students may retain the course techniques and procedures for at least six years. According to the ATLS, this is the most significant impact of all 11 . All 18 respondents consider care protocols o be extremely important in the service.
Not all doctors who were part of the clinical staff of the emergency service in the hospitals  and surgical specialists. We did not assess the quality of care, but the focal differences in trauma care priorities. This result raises a reflection and discussion about a pressing need now, that is, the figure of the expert in emergency care in the Emergency Units. Differences in medical care provided to victims of trauma depending on the medical specialty are unacceptable. However, the training, even in renowned courses, does not prepare the professional the same way a medical

Evaluation of care for traffic accidents victims made by on duty emergency physicians and surgeons in the emergency room residency in the area does. This conclusion is explained in the speech of professionals when they say they feel secure as to their capacity to diagnose and treat multiple trauma victims, but at the same time, they claim to need specialized training in trauma care. It is essential that the competent bodies and associations establish policies that allow emergency healthcare institutions to hire medical experts in the field. This would ensure a safe care, for both the patients who are attended by skilled professionals, and for the professionals who, due to their training, perform the activities with confidence, dynamism and efficiency.
