Validation of a Syndromic Case Definition for Detecting Emergency Department Visits Potentially Related to Marijuana

Abstract

OBJECTIVES:

Reliable methods are needed to monitor the public health impact of changing laws and perceptions about marijuana. Structured and free-text emergency department (ED) visit data offer an opportunity to monitor the impact of these changes in near-real time. Our objectives were to (1) generate and validate a syndromic case definition for ED visits potentially related to marijuana and (2) describe a method for doing so that was less resource intensive than traditional methods.

The Evolution of BioSense: Lessons Learned and Future Directions

The BioSense program was launched in 2003 with the aim of establishing a nationwide integrated public health surveillance system for early detection and assessment of potential bioterrorism-related illness. The program has matured over the years from an initial Centers for Disease Control and Prevention–centric program to one focused on building syndromic surveillance capacity at the state and local level.

Utilizing syndromic surveillance systems for climate-related outcomes

Adverse health effects related to climate change are currently being seen, and these adverse outcomes are likely to increase in the future. Syndromic surveillance systems can provide near-real time information which may be used for situational awareness as communities react to these adverse events. These systems may also provide another source of retrospective information, such as triage notes or diagnostic data at time of visit (e.g. blood pressure), which can also be used for planning and response.

Monitoring for Local Transmission of Zika Virus using Emergency Department Data

The first travel-associated cases of Zika virus infection in New York City (NYC) were identified in January 2016. Local transmission of Zika virus from imported cases is possible due to presence of Aedes albopictus mosquitos. Timely detection of local Zika virus transmission could inform public health interventions and mitigate additional spread of illness. Daily emergency department (ED) visit surveillance to detect individual cases and spatio-temporal clusters of locally-acquired Zika virus disease was initiated in June 2016.

Streamling Syndromic Surveillance Submission on a Dime: Oregon’s Experience

In 2012, the Oregon Public Health Division (OPHD) took advantage of the opportunity created by Meaningful Use, a Centers for Medicare & Medicaid Services (CMS) Incentive Program, to implement statewide syndromic surveillance. The Oregon syndromic surveillance project, or Oregon ESSENCE, began accepting MUcompliant HL7 2.5.1 data in late 2013. Early onboarding efforts were labor-intensive and led to the creation of a testing queue.

Facile Dashboard Creation Using Library of Syndromic Surveillance Visualization Tools

Public health surveillance largely relies on the use of surveillance systems to facilitate the identification and investigation of epidemiologic concerns reflected in data. In order to support public health response, these systems must present relevant information, and be user-friendly, dynamic, and easily-implementable. The abundance of R tools freely-available online for data analysis and visualization presents not only opportunities but also challenges for adoption in that these tools must be integrated so as to allow a structured workflow.

Monitoring the 2016 LA County Sand Fire with Multiple Early Detection Systems

On July 22, 2016, the Sand Fire began burning in the Santa Clarita Valley of Los Angeles County (LAC), CA. This urban-adjacent wildfire breached the city limits of Santa Clarita (population 180,000). Fueled by record heat and an ongoing exceptional drought, the Sand Fire burned over 40,000 acres in 13 days and caused a large increase in the air concentration of fine particulate matter. The syndromic surveillance team was tasked with reporting on possible health effects from the fire. Fire, asthma, and heat related data were monitored until the fire was reported as 98% contained.

Syndromic surveillance and UEFA Euro 2016 in France – Health impact assessment

France hosted 2016 UEFA European Football Championship between June 10 and July 10. In the particular context of several terrorist attacks occurring in France in 2015 [1], the French national public health agency « Santé publique France » (formerly French Institute for Public Health Surveillance-InVS) was mandated by the Ministry of Health to reinforce health population surveillance systems during the UEFA 2016 period. Six French regions and 10 main stadiums hosted 51 matches and several official and nonofficial dedicated Fan Zones were implemented in many cities across national territory.

Using Sydromic Surveillance to Track E-cigarette Related Emergency Department Visits

The North Dakota Department of Health (NDDoH) investigated the feasibility of using syndromic surveillance (SyS) data to identify health care visits due to electronic cigarette (e-cigarette) use. E-cigarettes have been associated with injuries and fatalities in all age groups, including young children attracted to the colorful liquid nicotine carriage packaging [1]. Previously, poison control data was the only resource available to the NDDoH for e-cigarette adverse outcomes surveillance.
