Direct transport versus inter-hospital transfer of trauma victims in the Brazilian Emergency Medical System.

Introduction: The Brazilian medical emergency services presented a significant development due to the investment in emergency care units, increasing the expansion of the services. However, there was a surge in need for secondary patient transfers, which served as the common link in a wide web of tertiary hospital access. This study aimed to assess the outcome of trauma patients who required secondary transfer. Patients and methods: This prospective observational cross-sectional study included 2302 patients (565 from the study group and 1737 from the control group) and compared the outcome of patients hospitalized for trauma referred by secondary transfer or those who directly visited the Emergency Unit of the municipality with a Brazilian medical emergency system. Results: As for the trauma mechanism, there was a predominance of blunt trauma (93.32 %), 34.5 % were elderly, 12.45 % suffered severe traumatic brain injury, and 18.44 % had severe trauma rate (injury severity score > 15). The outcome of death did not present a significant difference between the groups, even when evaluated considering possible risk factors, such as the elderly age (over 65 years of age) and trauma index. Conclusion: There was no significant difference in terms of the outcome of death in patients who underwent secondary transfer and those with direct access to medical emergency services. However, patients who underwent secondary transfer had an increase in the length of hospital stay.

International Society of Paediatric Surgical Oncology (IPSO) Surgical Practice Guidelines.

Most children with tumors will require one or more surgical interventions as part of the care and treatment, including making a diagnosis, obtaining adequate venous access, performing a surgical resection for solid tumors (with staging and reconstruction), performing procedures for cancer prevention and its late effects, and managing complications of treatment; all with the goal of improving survival and quality of life. It is important for surgeons to adhere to sound pediatric surgical oncology principles, as they are closely associated with improved local control and survival. Unfortunately, there is a significant disparity in survival rates in low and middle income countries, when compared to those from high income countries. The International Society of Paediatric Surgical Oncology (IPSO) is the leading organization that deals with pediatric surgical oncology worldwide. This organization allows experts in the field from around the globe to gather and address the surgical needs of children with cancer. IPSO has been invited to contribute surgical guidance as part of the World Health Organization Initiative for Childhood Cancer. One of our goals is to provide surgical guidance for different scenarios, including those experienced in High- (HICs) and Low- and Middle-Income Countries (LMICs). With this in mind, the following guidelines have been developed by authors from both HICs and LMICs. These have been further validated by experts with the aim of providing evidence-based information for surgeons who care for children with cancer. We hope that this initiative will benefit children worldwide in the best way possible. Simone Abib, IPSO President Justin T Gerstle, IPSO Education Committee Chair Chan Hon Chui, IPSO Secretary.

Implementation of a checklist to improve pediatric trauma assessment quality in a Brazilian hospital.

BACKGROUND: Trauma is the leading cause of death among children and adolescents in Brazil. Measurement of quality of care is important, as well as interventions that will help optimize treatment. We aimed to evaluate adherence to standardized trauma care following the introduction of a checklist in one of the busiest Latin American trauma centers. MATERIAL AND METHODS: A prospective, non-randomized interventional trial was conducted. Assessment of children younger than age 15 was performed before and after the introduction of a checklist for trauma primary survey assessment. Over the study period, each trauma primary survey was observed and adherence to each step of a standardized primary assessment protocol was recorded. Clinical outcomes including mortality, admission to pediatric intensive-care units, use of blood products, mechanical ventilation, and number of CT scans in the first 24 h were also assessed. RESULTS: A total of 80 patients were observed (39 pre-intervention and 41 post-intervention). No statistically significant differences were observed between the pre- and post-intervention groups in regard to adherence to checklist by specialty (57.7% versus 50.5%, p = 0.115) and outcomes. No mortality was observed. CONCLUSION: In our trauma center, the quality of the adherence to standardized trauma assessment protocols is poor among both surgical and non-surgical providers. The quality of this assessment did not improve after the introduction of a checklist. Further work aimed at organizing the approach to pediatric trauma including triage and trauma education specifically for pediatric providers is needed.

Evaluation of self-perception of mechanical ventilation knowledge among Brazilian final-year medical students, residents and emergency physicians.

OBJECTIVE:: To present self-assessments of knowledge about mechanical ventilation made by final-year medical students, residents, and physicians taking qualifying courses at the Brazilian Society of Internal Medicine who work in urgent and emergency settings. METHODS:: A 34-item questionnaire comprising different areas of knowledge and training in mechanical ventilation was given to 806 medical students, residents, and participants in qualifying courses at 11 medical schools in Brazil. The questionnaire's self-assessment items for knowledge were transformed into scores. RESULTS:: The average score among all participants was 21% (0-100%). Of the total, 85% respondents felt they did not receive sufficient information about mechanical ventilation during medical training. Additionally, 77% of the group reported that they would not know when to start noninvasive ventilation in a patient, and 81%, 81%, and 89% would not know how to start volume control, pressure control and pressure support ventilation modes, respectively. Furthermore, 86.4% and 94% of the participants believed they would not identify the basic principles of mechanical ventilation in patients with obstructive pulmonary disease and acute respiratory distress syndrome, respectively, and would feel insecure beginning ventilation. Finally, 77% said they would fear for the safety of a patient requiring invasive mechanical ventilation under their care. CONCLUSION:: Self-assessment of knowledge and self-perception of safety for managing mechanical ventilation were deficient among residents, students and emergency physicians from a sample in Brazil.

An evaluation of the professional, social and demographic profile and quality of life of physicians working at the Prehospital Emergency Medical System (SAMU) in Brazil

OBJECTIVE: To describe the profile of physicians working at the Prehospital Emergency Medical System (SAMU) in Brazil and to evaluate their quality of life. METHODS: Both a semi-structured questionnaire with 57 questions and the SF-36 questionnaire were sent to research departments within SAMU in the Brazilian state capitals, the Federal District and inland towns in Brazil. RESULTS: Of a total of 902 physicians, including 644 (71.4%) males, 533 (59.1%) were between 30 and 45 years of age and 562 (62.4%) worked in a state capital. Regarding education level, 45.1% had graduated less than five years before and only 43% were specialists recognized by the Brazilian Medical Association. Regarding training, 95% did not report any specific training for their work at SAMU. The main weaknesses identified were psychiatric care and surgical emergencies in 57.2 and 42.9% of cases, respectively; traumatic pediatric emergencies, 48.9%; and medical emergencies, 42.9%. As for procedure-related skills, the physicians reported difficulties in pediatric advanced support (62.4%), airway surgical access (45.6%), pericardiocentesis (64.4%) and thoracentesis (29.9%). Difficulties in using an artificial ventilator (43.3%) and in transcutaneous pacing (42.2%) were also reported. Higher percentages of young physicians, aged 25-30 years (26.7 vs 19.0%; p<0.01), worked exclusively in prehospital care (18.0 vs 7.7%; p<0.001), with workloads >48 h per week (12.8 vs 8.6%; p<0.001), and were non-specialists with the shortest length of service (<1 year) at SAMU (30.1 vs 18.2%; p<0.001) who were hired without having to pass public service exams* (i.e., for a temporary job) (61.8 vs 46.2%; p<0.001). Regarding quality of life, the pain domain yielded the worst result among physicians at SAMU. CONCLUSIONS: The doctors in this sample were young and within a few years of graduation, and they had no specific training in prehospital emergencies. Deficiencies ...
