- Alcohol and drug involvement in motorcycle driver injuries in the city of Sao Paulo, Brazil: Analysis of crash culpability and other associated factors(2016) CARVALHO, Heraclito Barbosa de; ANDREUCCETTI, Gabriel; REZENDE, Marcelo Rosa; BERNINI, Celso; SILVA, Jorge Santos; LEYTON, Vilma; GREVE, Julia Maria D'AndreaBackground: Earlier studies have already identified that a greater proportion of injured drivers are under the effects of illicit drugs than alcohol in Brazil, but the crash risk attributable to each substance is still unknown. Methods: Injured motorcycle drivers who were involved in traffic accidents in the West Zone of the city of Sao Paulo were recruited for a cross-sectional study based on crash culpability analysis. Alcohol and drug positivity among drivers was evaluated according to their responsibility for the crash. Culpability ratios were generated based on the proportion of drivers who were deemed culpable in relation to those considered not culpable according to the use of drugs and alcohol. Results: Of the 273 drivers recruited, 10.6% tested positive for alcohol. Among those who were also tested for drugs (n=232), 20.3% had consumed either alcohol and/or other drugs, 15.5% of whom were positive only for drugs other than alcohol, specifically cannabis and cocaine. Drivers who tested positive for alcohol were significantly less likely to possess a valid driver's license and to report driving professionally, whereas those who had consumed only drugs were more likely to drive professionally. The culpability ratio estimated for alcohol-positive drivers was three times higher than that for alcohol-free drivers, showing a superior ratio than drivers who had consumed only drugs other than alcohol, who presented a 1.7 times higher culpability ratio than drug-free drivers. Conclusion: Substance use was overrepresented among culpable motorcycle drivers, with alcohol showing a greater contribution to crash culpability than other drugs.
- Factors related to motorcycle accidents with victims: an epidemiological survey(2018) GREVE, Júlia Maria D’Andréa; RESENDE, Marcelo Rosa; CARVALHO, Heráclito Barbosa de; ANDREUCCETTI, Gabriel; BERNINI, Celso O.; LEYTON, VilmaOBJECTIVE: To evaluate the factors associated with traffic motorcycles accidents. METHODS: The sample consisted of 285 motorcycle accident victims in São Paulo. Data were collected from 24-hour emergency service shifts regarding: conditions of the victims, security equipment, road and vehicle conditions. RESULTS: Victims were mostly young men (92%); 23% used the motorcycle for work (average: 8 hours per day); 45% had owned a motorcycle for less than two years; 77% were licensed motorcycle drivers; 33% had less than four years of qualification; 31% had attended a course of defensive driving. Severe lesions were identified in 67% of the unlicensed drivers. Polytrauma occurred in 9% head trauma in 5% of the entire population. Lower limb fractures occurred more frequently than upper limb (17% vs. 12%). Most wore helmets (90%) but only 18% wore helmet, boots and jacket. Positive readings for alcohol (7%) and drugs (14%) occurred in 21% of victims. Most accidents occurred as a consequence of imprudence (88%), during the day (67%), in dry weather conditions (94%). A side impact was registered in 48% of cases; 80% of motorcycles had an engine capacity up to 250 cc. In 51% of the accidents the person responsible for the accident was the driver of the other vehicle in the accident. CONCLUSION: Most accidents involve motorcyclists who are young male adults, use the motorcycle as a means of transport and do not consider safety, defensive driving and the use of alcohol and drugs as important factors.
- 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.
