Trial Summary

What is the purpose of this trial?

The purpose of this research study is to understand people's alcohol use in public places and their risks for harm. The overall goal of this study is to test the effects of subsidized ridesharing as an intervention to reduce self-reported alcohol-impaired driving, along with alcohol consumption and changes to mobility.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Ridesharing Vouchers for Drunk Driving?

Research shows that voucher-based incentives can improve adherence to treatments and increase access to services. For example, vouchers have been effective in substance abuse treatments and family planning programs by encouraging participation and improving outcomes. Additionally, ridesharing programs have been found to enhance access to healthcare, making participants feel safer and more empowered. ^{1 2 3 4 5}

Is it safe to use ridesharing vouchers to prevent drunk driving?

The safety of using ridesharing vouchers to prevent drunk driving has not been directly studied, but concerns about child safety in rideshare vehicles have been noted, particularly due to the lack of appropriate child restraints. This suggests a need for careful consideration of safety measures when using ridesharing services. ^{6 7 8 9 10}

How does the treatment of ridesharing vouchers for drunk driving differ from other treatments?

Ridesharing vouchers for drunk driving are unique because they provide a practical, non-medical solution by offering an alternative transportation option to prevent impaired driving, unlike traditional treatments that might focus on counseling or medication to address alcohol use. ^{11 12 13 14 15}

Findings from Research

Health care voucher programs can significantly improve access to contraceptive services for underserved populations, particularly in low- and middle-income countries, by targeting marginalized groups and addressing barriers to care.

Effective management and monitoring of voucher systems are crucial for their success, as separating implementation from management can enhance transparency and accountability, ultimately leading to better health outcomes.

Voucher-based incentives have been proven effective in improving retention and increasing abstinence in cocaine-dependent outpatients, with plans for further testing in community clinics.

This approach shows promise for treating various substance dependencies, including alcohol, marijuana, nicotine, and opioids, and is particularly beneficial for special populations like pregnant women and adolescents.

Participation in a nonemergency medical transportation program for Medicare ACO members led to an increase in outpatient visits (9.2 visits per person per year) and higher outpatient spending ($4,420), indicating improved access to healthcare services.

Despite the increased healthcare utilization, the program did not result in cost savings and showed no difference in inpatient admissions or emergency department visits, suggesting that these transportation services primarily enhance access rather than reduce overall healthcare costs.

In a 12-week clinical trial with 58 participants, a voucher-based incentive program significantly improved adherence to naltrexone maintenance treatment, especially in the contingent group who received vouchers for each dose ingested.

The contingent group not only retained treatment longer but also ingested more doses of naltrexone compared to the non-contingent and no-voucher groups, highlighting the effectiveness of targeted incentives in supporting recovery from opioid dependence.

Voucher-based reinforcement therapy (VBRT) has been shown to be effective in treating substance use disorders, with an average effect size of 0.32 from 30 studies, indicating a moderate positive impact on treatment outcomes.

Factors such as the immediacy of voucher delivery and the monetary value of the vouchers were found to enhance the effectiveness of VBRT, suggesting that optimizing these elements could improve treatment results.

A significant 37.2% of young people surveyed reported riding with a drunk or drugged driver in the past month, highlighting a serious risk behavior in nightlife contexts.

Factors such as impulsivity, preference for private car use, and living in southern European countries were linked to this behavior, indicating a need for targeted awareness campaigns to address the social acceptance of riding with impaired drivers.

Offering free safe rides (SRs) home can lead to a higher average blood alcohol concentration (BAC) among drinkers, but only a small percentage (24%) of users moved from a low-risk to a high-risk BAC category when using SRs.

Most respondents (72%) did not change their BAC categories when using SRs, and the overall infrequent use of SRs (about 3.69 times per year) suggests that concerns about increased drinking due to SR availability may be overstated.

A survey of 631 Australian parents revealed that many do not travel in rideshare vehicles with their children, primarily due to concerns about cost, driver safety, and the inconvenience of using child restraints.

When parents do use rideshare services, they are less likely to use appropriate child restraints compared to private vehicles, highlighting a need for specific policies and education to improve child safety in these settings.

The Evesham Saving Lives program, which subsidized rideshare trips from bars and restaurants, led to an 18% reduction in injury crashes in participating townships, indicating its effectiveness in preventing alcohol-related traffic injuries.

The program was particularly effective at night, with a 38% reduction in crashes during those hours, and is estimated to have saved around three lives and prevented approximately 371 injuries, highlighting its potential for significant public health benefits.

A survey of 2017 U.S. adults revealed that 68% of parents with children under 10 have used ridesharing services, indicating a significant trend in rideshare use among families.

Most U.S. states do not require child restraint systems in rideshare vehicles, which raises safety concerns as many children may be at risk of injury due to inadequate restraint during rideshare trips.
