Syndromes

Assessing health disparities and access to healthcare has been an important issue for emergency preparedness and response efforts in the Denver metropolitan area. There have been several high profile MJ-related illness outbreaks in the US over the past 2 years. The legalization and retail sale of recreational MJ in Colorado necessitates enhanced surveillance for adverse effects from MJ use. TCHD and DPH coordinated to use syndromic surveillance data to provide situational awareness and timely outbreak detection related to MJ, including health disparities and overall impacts on population health.

Objective

Adverse health effects related to marijuana (MJ) use may disproportionately impact populations based on age or gender. To explore whether disparities exist among persons seeking emergency department (ED) care related to MJ use, Tri-County Health Department (TCHD) and Denver Public Health (DPH) developed MJ use case definitions, described patient demographics, mapped patients’ geographic distribution relative to marijuana dispensary locations, evaluated access to healthcare, and investigated the potential impact of MJ on pediatric health.

Nationally, deaths due to opioid overdose have continually increased for the past 15 years . Deaths specifically related to heroin increased more than four-fold between 2002 and 2014. Hospital inpatient discharge data provide information on non-fatal overdoses, but include a significant lag in reporting time. Syndromic ED visit data provide near real-time identification of public health issues and can be leveraged to inform public health actions on the emerging threat of drug overdose.

Objective

To develop and evaluate syndrome definitions for the identification of acute unintentional drug overdose events including opioid, heroin, and unspecified substances among emergency department (ED) visits in Virginia.

In 2016, the World Health Organization declared Zika virus a global public health emergency. Zika infection during pregnancy can cause microcephaly and other fetal brain defects. To facilitate clinicians’ ability to detect Zika, various syndrome definitions have been developed. 

Objective

To develop and validate a Zika virus disease syndrome definition within the GUARDIAN (Geographic Utilization of Artificial Intelligence in Real-Time for Disease Identification and Alert Notification) surveillance system.
