Background : Electronic platform surveys are ideal for self-administration in adolescent populations, as nearly all adolescents in the US report using or having access to smartphones. This technology-savvy population seems prepared to graduate away from paper surveys. Despite predicted advantages of using smartphones for data collection, there is a surprising lack of data regarding the use of this mode for surveillance of substance use trends among adolescent populations. Objectives : The objective of this study was to evaluate completion rates, times, and responses of high school students taking the Secondary Student Life Survey: Nevada (SSLS:NV) on their own personal smartphones compared to provided computers or tablets. Methods: The SSLS:NV is a web-based survey designed to assess adolescent beliefs, attitudes, and use-trends surrounding substance use. The SSLS:NV was self-administered via self-selected device (personal vs. provided) within one class period to approximately one thousand 9th-12th grade students in December 2016. Data was collected and analyzed to compare outcomes by computer, tablet, or smartphone. Statistical analysis was performed in SPSS 23.0 using χ 2 or Fisher's exact test for categorical data and one-way ANOVA for continuous data. Results : SSLS:NV completion times averaged 21 min overall ( p  = .193). Differences were seen with completion rates of 86% smartphone 94% tablet, and 95% computer ( p  < .001), while responses to lifetime substance use were similar across all groups. Conclusions/Importance : The current study provides proof of concept that personal smartphones are effective in achieving more comprehensive adolescent substance use surveillance within a relatively short amount of time, while retaining robust response rates.

Introduction: Burning Man is a large weeklong outdoor arts festival held annually in the rugged and austere Black Rock Desert in northern Nevada. The 2011 event presented several unusual challenges in terms of emergency medical services (EMS) and medical care provision., Objective: This paper details the planning and subsequent emergency medical care for Burning Man 2011., Methods: This was a retrospective, observational review of the preparation, management, and medical care at Burning Man 2011., Results: Attendance at Burning Man 2011 was 53,735. Of these attendees, 2,307 were treated in the field hospital. While most patients had minor injuries, 33 were subsequently transported to a hospital (28 by ambulance and five by helicopter). The most common conditions treated were soft-tissue injuries, dehydration, eye problems, and urinary tract infections. There was one death (subarachnoid hemorrhage) and one patient in cardiac arrest (thoracic aortic dissection) who was successfully resuscitated and transferred. Burning Man 2011 presented numerous challenges in provision of EMS and medical care because of attendance size, the austere environment, and significant distance (150 miles) to definitive medical care. EMS operations included six dedicated ambulances, three quick-response vehicles, two first-aid stations, and a physician-staffed field hospital. The hospital had limited diagnostic capabilities (e.g., x-ray, ultrasound, basic laboratory analysis) and a limited formulary. We found that the use of physicians was necessary because much of the care provided was beyond the scope of paramedics., Conclusions: We describe the preparation and medical care for a large outdoor mass-gathering event held in a remote and austere environment. We met the stated goals of providing needed medical care while minimizing the need to transport attendees offsite for additional care. Our experience with Burning Man 2011 may aid planners with similar events.
