Interactive Virtual Presence to Remotely Assist Parents With Car Seat Installation

Area of Science:

• Public Health
• Pediatric Safety
• Health Technology

Background:

• Motor vehicle crashes are a leading cause of preventable pediatric death.
• Incorrect installation and usage of child restraints (car seats) are common, affecting approximately 80% of users.
• Current access to certified child passenger safety technicians for individualized appointments is insufficient to meet demand.

Purpose of the Study:

• To evaluate the noninferiority of remote child restraint installation assistance compared to on-site assistance.
• To assess the accuracy of child restraint installation and usage following virtual versus in-person guidance from certified technicians.

Main Methods:

• A phase III randomized noninferiority clinical trial involving 1509 participants across 7 US locations.
• Participants were assigned to receive assistance from a certified technician either live and on-site or remotely via an interactive virtual presence smartphone application.
• Objective scoring was used to assess the accuracy of child restraint installation and usage.

Main Results:

• The on-site group achieved a mean of 97.7% correct installation/usage, while the remote group achieved 95.6%.
• The adjusted difference of 1.80% fell within the noninferiority margin of 2.5%, indicating comparable effectiveness (P=.006).
• Sensitivity analyses controlling for various demographic and installation factors confirmed these findings.

Conclusions:

• Remote assistance via interactive virtual presence is a noninferior method for educating caregivers on correct child restraint installation and usage compared to on-site assistance.
• Widespread adoption by various agencies could significantly enhance pediatric public health outcomes, particularly for underserved communities.
• This technology offers a scalable solution to improve child passenger safety nationwide.
