Description

The rate of drug overdose deaths in the United States has increased steadily since 2000. Injection drug use, a practice associated with infectious disease transmission, has likely increased along with this upward trend in drug overdoses. Injection drug use surveillance is difficult to conduct at a public health department because there are no specific Internal Classification of Diseases codes to identify this risk behavior in hospital discharge or vital registration data. Maricopa County Department of Public Health Office of Epidemiology aimed to identify indications of injection drug use within data from the Office of the Medical Examiner.

Objective: To determine whether data from the Office of the Medical Examiner are useful for conducting injection drug use surveillance in Maricopa County, Arizona, and to describe the characteristics of decedents who died from a drug overdose, were investigated by the county's medical examiner, and had an indication of injection drug use.

This syndrome attempts to capture Opioid, Cocaine and Meth Injection Drug Use hospital visits. The syndrome was developed using NSSP ESSNECE and evaluated on Maricopa County emergency department and inpatient data. Fields used in ESSENCE include Admit Reason Combo, Cheif Complaint History and Discharge Diagnosis.

Arizona reports an average of 116 cases of West Nile virus (WNV) each year, and in 2015, Arizona saw a reemergence of St. Louis encephalitis (SLE) virus. In addition, Arizona is at risk for importation of viruses such as chikungunya, dengue, and Zika due to an abundance of Aedes aegypti mosquitoes in many parts of the state. Rapid identification of potential cases of arboviral disease (borne by mosquitoes and ticks) is critical to implementing appropriate public health responses.

In January 2017, the NSSP transitioned their BioSense analytical tools to Electronic Surveillance System for Early Notification of Community-Based Epidemics (ESSENCE). The chief complaint field in BioSense 2.0 was a concatenation of the record's chief complaint, admission reason, triage notes, and diagnostic impression. Following the transition to ESSENCE, the chief complaint field was comprised of the first chief complaint entered or the first admission reason, if the chief complaint was blank. Furthermore, the ESSENCE chief complaint field was electronically parsed (i.e., the original chief complaint text was altered to translate abbreviations and remove punctuation). This abstract highlights key findings from Maricopa County Department of Public Health's evaluation of the new chief complaint field, its impact on heat-related illness syndromic surveillance, and implications for ongoing surveillance efforts.

Objective:

To evaluate the effect and implications of changing the chief complaint field during the National Syndromic Surveillance Program (NSSP) transition from BioSense 2.0 analytical tools to BioSense Platform ESSENCE.

On 3/29/2017, the Maricopa County Department of Public Health (MCDPH) received three reports of confirmed HAV infection from an onsite clinic at Campus A that assists individuals experiencing homelessness, a population at risk for HAV transmission. To identify the scope of the problem, the department initiated rapid HAV infection case detection using NSSP ESSENCE.

Objective:

To demonstrate the utility of the National Syndromic Surveillance Program’s (NSSP) version of the Electronic Surveillance System for Early Notification of Community-based Epidemics (ESSENCE) for case detection during a 2017 outbreak of hepatitis A virus (HAV) infection among persons experiencing homelessness in Maricopa County, Arizona.

Timely identification of arboviral disease is key to prevent transmission in the community, but traditional surveillance may take up to 14 days between specimen collection and health department notification. Arizona state and county health agencies began monitoring National Syndromic Surveillance Program BioSense 2.0 data for patients infected with West Nile virus (WNV), St. Louis encephalitis virus (SLEV), chikungunya, or dengue virus in August 2015. Zika virus was added in April 2016. Our novel methods were presented at the International Society for Disease Surveillance 2015 Annual Conference. Twice per week, we queried patient records from 15 Maricopa County BioSense-enrolled emergency department and inpatient hospitals for chief complaint keywords and discharge diagnosis codes. Our Case Investigation Decision Tree helped us determine whether records had a high or low degree of evidence for arboviral disease and necessitated further investigation. This study evaluated how Arizona’s protocol for conducting syndromic surveillance compared to traditional arboviral surveillance in terms of accuracy and timeliness in Maricopa County from August 2015 through December 2016.

Objective:

To evaluate Arizona’s arboviral syndromic surveillance protocol in Maricopa County.
