- Drink driving and speeding in Sao Paulo, Brazil: empirical cross-sectional study (2015-2018)(2019) ANDREUCCETTI, Gabriel; LEYTON, Vilma; CARVALHO, Heraclito Barbosa; SINAGAWA, Daniele M.; BOMBANA, Henrique S.; PONCE, Julio C.; ALLEN, Katharine A.; VECINO-ORTIZ, Andres I.; HYDER, Adnan A.Objectives To evaluate the prevalence of drink driving and speeding during 2015-2018 in Sao Paulo, Brazil. Design Cross-sectional observational study. Setting Roads representing the five main regions of the city of Sao Paulo in Brazil, one of the world's largest urban areas. Participants Drivers (N=10294) stopped at routine roadside breath testing checkpoints and those driving in selected roads for speeding measurement (N=414664). Primary and secondary outcome measures Microwave radar guns were used to measure the speed of vehicles, while the prevalence of drivers under the influence of alcohol was observed in police checkpoints. Data were collected during three consecutive years (2016-2018) following a baseline study established in 2015 using a city-level representative sample of observational data representing all days of the week. Results Alcohol-related fatalities kept at a constantly high percentage, with 39% of road traffic deaths involving alcohol in 2016. Drivers testing above the legal breath alcohol concentration limit showed a decreasing trend, from 4.1% (95% CI 2.9% to 5.5%) at baseline to 0.6% (95% CI 0.2% to 1.2%) in the end of 2018 (p<0.001); however, more than half of drivers refused breath tests at checkpoints despite steep legal penalties. The prevalence of speeding among all vehicles decreased from 8.1% (95% CI 7.9% to 8.2%) to 4.9% (95% CI 4.7% to 5.1%) by the end of 2016 (p<0.001), but then increased again to 13.5% (95% CI 13.2% to 13.9%) at the end of the study period (p<0.001). Conclusions Drink driving rates have reduced, likely due to an increase in drivers refusing breath alcohol tests, while speeding rates have increased significantly by the end of the study period, particularly among motorcycles. Future strategies aiming at reducing road traffic injuries in the major Brazilian city should tailor drink driving and speeding enforcement based on the new evidence provided here.
- Use of alcohol and illicit drugs by trauma patients in Sao Paulo, Brazil(2022) BOMBANA, Henrique Silva; BOGSTRAND, Stig Tore; GJERDE, Hallvard; JAMT, Ragnhild Elen Gjulem; CARVALHO, Heraclito Barbosa de; ANDREUCCETTI, Gabriel; BERNINI, Celso de Oliveira; MUNOZ, Daniel Romero; LEYTON, Vilma; GREVE, Julia Maria D'AndreaIntroduction: Alcohol and illicit drugs impair cognitive and psychomotor skills and may thereby increase the risk of involvement in a road traffic crash and other types of injuries. However, the knowledge on the use of psychoactive substances among injured patients presenting to emergency departments in low and middle-income countries remains limited. Aims: To estimate the prevalence of alcohol and illicit drug use among patients with traumatic injuries admitted to an emergency department in Sao Paulo, Brazil. Methods: Blood samples from injured patients requiring hospitalization for more than 24 h due to road traffic crashes, falls, or violence, were collected from July 2018 to June 2019. The samples were analyzed for alcohol and illicit drugs. Results: A total of 376 patients were included in this study; the median age was 36 years and 80% of patients were male. The majority (56%) of injuries resulted from road traffic crashes, with approximately half of them being motorcyclists. Alcohol, drugs, or both were detected in 32% of samples. The proportion that tested positive was highest for males (35%), for the age group 18-39 years (41%), for singles (43%), and for patients injured at nighttime (4 4%). Patients injured due to violence had the highest prevalence of alcohol or drugs in their blood samples (4 4%). Alcohol was most prevalent (23%), followed by cocaine (12%) and cannabis (5%). Conclusion: The use of alcohol and illicit drugs was common among injured patients in Sao Paulo; it was likely a contributing factor in a third of the injurious accidents. Alcohol was the most prevalent substance followed by cocaine and cannabis.
- Factors Contributing to Traffic Accidents in Hospitalized Patients in Terms of Severity and Functionality(2023) CANONICA, Alexandra Carolina; ALONSO, Angelica Castilho; SILVA, Vanderlei Carneiro da; BOMBANA, Henrique Silva; MUZAURIETA, Aurelio Alberto; LEYTON, Vilma; GREVE, Julia Maria D'AndreaTrauma-related injuries in traffic-accident victims can be quite serious. Evaluating the factors contributing to traffic accidents is critical for the effective design of programs aimed at reducing traffic accidents. Therefore, this study identified which factors related to traffic accidents are associated with injury severity in hospitalized victims. Factors related to traffic accidents, injury severity, disability and data collected from blood toxicology were evaluated, along with associated severity and disability indices with data collected from toxicology on victims of traffic accidents at the largest tertiary hospital in Latin America. One hundred and twenty-eight victims of traffic accidents were included, of whom the majority were young adult men, motorcyclists, and pedestrians. The most frequent injuries were traumatic brain injury and lower-limb fractures. Alcohol use, hit-and-run victims, and longer hospital stays were shown to lead to greater injury severity. Women, elderly individuals, and pedestrians tend to suffer greater disability post-injury. Therefore, traffic accidents occur more frequently among young male adults, motorcyclists, and those who are hit by a vehicle, with trauma to the head and lower limbs being the most common injury. Injury severity is greater in pedestrians, elderly individuals and inebriated individuals. Disability was higher in older individuals, in women, and in pedestrians.
