IMPORTANCE Motor vehicle crashes (MVCs) are an important public health concern. Recent trends suggest that introducing rideshare services has decreased the incidence of MVCs. However, detailed analyses linking rideshare volume, convictions for impaired driving, and nonfatal MVC traumas remain inconclusive.OBJECTIVE To determine if there is an association between rideshare use and MVC traumas and convictions for impaired driving in Houston, Texas. DESIGN, SETTING, AND PARTICIPANTSThis multicenter cohort study was conducted between January 2007 and November 2019 with hospital data from the Red Duke Trauma Institute within the Memorial Hermann Hospital-Texas Medical Center and Ben Taub General Hospital. Rideshare data from Uber and Google covered trips taken within Houston, Texas, from February 2014 (the date of deployment of Uber to Houston) to December 2018. Impaired driving convictions included all indictments made by the Harris County, Texas, District Attorney's office from January 2007 to December 2018. All adults with MVC traumas evaluated at both centers in the study population (individuals >16 years with a mechanism of injury classified under "motor vehicle collision") were included. Impaired driving incidents were included only if the final legal outcome was conviction. MAIN OUTCOMES AND MEASURESThe primary study outcomes were the incident rate ratios for hourly MVC traumas and daily impaired driving convictions. RESULTS A total of 23 491 MVC traumas (involving patients with a mean [SD] age of 37.9 [17.8] years and 14 603 male individuals [62.1%]), 93 742 impaired driving convictions, and more than 24 million Uber rides were analyzed. Following the introduction of Uber in February 2014, MVC traumas decreased by 23.8% (from a mean [SD] of 0.26 [0.04] to 0.21 [0.06] trauma incidents per hour) during peak trauma periods (Friday and Saturday nights).The incident rate ratio of MVC traumas following Uber deployment was 0.33 (95% CI, 0.17-0.67) per 1000 indexed rides (P = .002). Furthermore, rideshare use was associated with a significant, geographically linked reduction in impaired driving convictions between January 2014 to December 2019 (incidence rate ratio, 0.76 [95% CI, 0.73-0.78]; P < .001). CONCLUSIONS AND RELEVANCEIn this study, introducing rideshare services in the Houston metropolitan area was associated with significant reductions in MVC traumas and impaired driving convictions. Increased use of rideshares may be an effective means of reducing impaired driving and decreasing rate of MVC traumas.
A review of liver trauma treated by the major trauma care facilities of Tasmania in the 5 year period between 1989 and 1993 is presented. The aim of this retrospective review was to provide an audit of the management of liver trauma in the island of Tasmania and to analyse the risk factors contributing to mortality and major morbidity. Thirty‐seven patients were treated with a median Injury Severity Score (ISS) of 14 (range 9–34). The overall mortality rate of this series was 5.8%. Age, mechanism of injury (blunt or penetrating), delay prior to hospital presentation and modality of treatment (operative or non‐operative) were not significant risk factors for mortality and morbidity; however, transfusion requirement of over 10 units of blood (P < 0.005), ISS score of over 20 (P < 0.005). haemodynamic instability at presentation (P < 0.05) and a Hepatic Injury Score (HIS) grade of 3 or more (P < 0.05) were statistically significant risk factors.
Neurosurgery is male dominated with women representing only 12% of residents and 5% of practicing neurosurgeons. The conflicting demands of training versus pregnancy and motherhood are significant deterrents to women entering the field. We examined pregnancy incidence and timing, perinatal complications, and the perceived career impact of motherhood on female neurosurgeons using an anonymous survey of 643 training, practicing, and retired female neurosurgeons from the United States. Among 260 respondents, 50.8% (132/260) reported pregnancies, with an average age at first pregnancy that was significantly higher than the national average (32.1 vs 26.3 yr). In all, 40.1% (53/132) of respondents reported perinatal complications in at least one of their pregnancies. Only 25% (33/132) of respondents noted designated program maternity allowances. The most significant challenges associated with being a mother and neurosurgeon reported were issues relating to work/life balance, “mommy guilt,” and sleep deprivation. A majority of respondents, 70.1% (82/116), reported fear of backlash from co-residents, partners, and staff, as well as hindered career advancement related to childbearing. Female neurosurgeons face challenges surrounding family planning different from those faced by male practitioners. Higher perinatal and fetal complications, backlash from colleagues, and demanding workload are significant issues. Progress requires institutional support and mentorship for women to create a more diverse field of practitioners.
