ObjectiveUsing a syndromic surveillance system to understand the magnitude and risk factors related to heat-related illness (HRI) in Pinal County, AZ.IntroductionExtreme heat is a major cause of weather-related morbidity and mortality in the United States (US).1 HRI is the most frequent cause of environmental exposure-related injury treated in US emergency departments.2 More than 65,000 emergency room visits occur for acute HRI each summer nationwide.3 In Arizona, HRI accounts for an estimated 2,000 emergency room patients and 118 deaths each year.4 As heat-related illness becomes increasingly recognized as a public health issue, local health departments are tasked with building capacity to conduct enhanced surveillance of HRI in order to inform public health preparedness and response efforts. In Pinal County, understanding the magnitude and risk factors of HRI is important for informing prevention efforts as well as developing strategies to respond to extreme heat.MethodsTo gain a better understanding of the magnitude of HRI in Pinal County, historical cases were reviewed from hospital discharge data (HDD) from 2010-2016. Cases were included if the discharge record included any ICD codes consistent with HRI (ICD-9 codes 992 or ICD-10 codes T67 or X30) and if the patient’s county of residence was Pinal County. Recent HRI cases during the summer of 2017 were identified using the National Syndromic Surveillance Program BioSense Platform. The ESSENCE syndromic surveillance tool within the BioSense Platform includes data reported by local hospitals. This data can be used to detect abnormal activity for public health investigation. HRI cases were identified in ESSENCE based on ICD-10 codes and chief complaint terms according to a standardized algorithm developed by the Council of State and Territorial Epidemiologists.1 Both emergency department and admitted patients with a HRI were abstracted from HDD and ESSENCE. To assess HRI risk factors for the summer of 2017, a survey instrument was developed. Survey questions included the nature and location of the HRI incident, potential risk factors, and knowledge and awareness of HRI. Cases were identified in ESSENSE on a weekly basis from May 1, 2017-September 12, 2017, and follow up phone interviews were conducted with eligible cases. For HRI cases eligible for interview, three attempts were made to contact the patient by phone. Cases were excluded if the patient was incarcerated, deceased, or did not have a HRI upon medical record review. An exploratory analysis was performed for the data from HDD, ESSENCE, and interviews.ResultsPinal County Public Health Services District identified 1,321 HRI cases from 2010-2016, an average of 189 per year. Hospital discharge data suggest HRI cases are more likely to occur in males between the ages of 20-44 years old (27%). It is also notable that a sharp increase in HRI cases is observed each year in mid-to-late June, with an estimated 14% of annual cases occurring during the third week of June. Further analysis of HDD showed 31% of cases received medical treatment in Casa Grande in central Pinal County. Between May 1st and September 12th of 2017, 161 HRI cases were detected using ESSENCE. Of which 149 cases were determined to be HRI; 22 cases did not have contact information, and 4 cases were ineligible due to incarceration or death. A total of 31 HRI cases were interviewed out of the eligible 123 ESSENSE cases (25% response rate). Interview data indicated occupational exposure to extreme heat as a major risk factor for HRI. Additional risk factors reported during interviews included exposure to extreme heat while at home or traveling, although interview results are not representative due to a small sample size (n=31).ConclusionsSyndromic surveillance combined with interviews and a review of HDD provides an informative approach for monitoring and responding to HRI. Data suggest Pinal County should expect an increase in HRI cases by mid-June each year, typically coinciding with the first National Weather Service Extreme Heat Warning of the season. Preliminary results suggest that cases occur more frequently in working males ages 20-44 years old in occupations that expose workers to extreme heat conditions. Additional information is needed to assess risk factors for HRI among vulnerable populations in Pinal County who were not represented in this study, including individuals who are homeless, undocumented, elderly, or in correctional facilities. Future areas for improvement include improving the phone interview script to include English and Spanish language versions and performing medical record abstractions on all HRI cases. Enhanced syndromic surveillance is recommended to provide information on risk factors for HRI to inform prevention efforts in Pinal County.References1.

ObjectiveThis panel will:• Discuss the importance of identifying and developing success stories • Highlight successes from state and local health departments to show how syndromic surveillance activities enhance situational awareness and address public health concerns • Encourage discussion on how to further efforts for developing and disseminating success stories
ObjectiveTo develop a protocol for enhancing traditional arboviral surveillance with syndromic surveillance and to evaluate the protocol for accuracy, effectiveness, and timeliness.
ObjectiveThe National Syndromic Surveillance Program (NSSP) Community of Practice (CoP) works to support syndromic surveillance by providing guidance and assistance to help resolve data issues and foster relationships between jurisdictions, stakeholders, and vendors. During this presentation, we will highlight the value of collaboration through the International Society for Disease Surveillance (ISDS) Data Quality Committee (DQC) between jurisdictional sites conducting syndromic surveillance, the Centers for Disease Control and Prevention’s (CDC) NSSP, and electronic health record (EHR) vendors when vendor-specific errors are identified, using a recent incident to illustrate and discuss how this collaboration can work to address suspected data anomalies.IntroductionOn November 20, 2017, several sites participating in the NSSP reported anomalies in their syndromic data. Upon review, it was found that between November 17-18, an EHR vendor’s syndromic product experienced an outage and errors in processing data. The ISDS DQC, NSSP, a large EHR vendor, and many of the affected sites worked together to identify the core issues, evaluate ramifications, and formulate solutions to provide to the entire NSSP CoP.DescriptionOn November 20, 2017, several sites participating in the NSSP reported anomalies in their syndromic data.

Participants from all three stakeholder groups, sites conducting syndromic surveillance, the NSSP, and vendor representatives, will be invited to share their experiences, successes, and concerns.
ObjectiveThe objective of this session is to discuss syndromic surveillance evaluation activities. Panel participants will describe contexts and importance of selected evaluation and performance measurement activities in NSSP. Discussions will explore ways to strengthen evaluation in syndromic surveillance activities in the future.IntroductionSyndromic surveillance uses near-real-time Emergency Department healthcare and other data to improve situational awareness and inform activities implemented in response to public health concerns. The National Syndromic Surveillance Program (NSSP) is a collaboration among state and local health departments, the Centers for Disease Control and Prevention (CDC), other federal organizations, and other entities, to strengthen the means for and the practice of syndromic surveillance. NSSP thus strives to strengthen syndromic surveillance at the national and the state, and local levels through the coordinated activities of the involved partners and the development and use of advanced technologies, such as the BioSense platform. Evaluation and performance measurement are crucial to ensure that the various strategies and activities implemented to strengthen syndromic surveillance capacity and practice are effective. Evaluation activities will be discussed at this session and feedback from audience will be sought with the goal to further strengthen evaluation activities in the future.DescriptionSyndromic surveillance practice among NSSP grant recipients: findings from a telephone based survey – S. Romano This presentation will highlight the development and implementation of a survey among the NSSP grant recipients about their syndromic surveillance practice. The objectives of the survey was to develop knowledge and understanding about: a) characteristics of syndromic surveillance practice at the state and local level among jurisdictions that are NSSP grant recipients; b) challenges encountered by these jurisdictions in conducting syndromic surveillance; and c) strategies that may help address these challenges. The objectives and methods of the survey will be described in detail. The survey is expected to be implemented before the end of this year. Preliminary findings will be presented if available. Lessons learned and strategies to consider for strengthening syndromic surveillance practice will be discussed.Defining a sustainable approach to syndromic surveillance through the AZ BioSense Workgroup Charter – K. Collier, S. Johnston The Arizona BioSense Workgroup has developed a five year charter outlining the method and measures used for implementation and adoption of syndromic surveillance in Arizona. Membership consists of clinicians, IT and public health. The mission and vision help to establish a foundation for building capacity and quality of the syndromic surveillance data, improved population health and emergency response through timely and effective use of the data. Cross-cutting topics resulted in a process for assessing training needs, establishing protocols and evaluation of use cases, shared plans for situational awareness and making public health decisions. This talk will discuss the collaborative approach and how lessons learned will inform future activities.User Acceptance Testing to inform development and enhancement of the BioSense Platform – C. Davis Between June, 2016 and January, 2017, NSSP operationalized an updated BioSense Platform for conducting syndromic surveillance. The platform included ESSENCE, a software that enables analysis and visualization of syndromic surveillance data and the Access Management Center, a tool that enables jurisdictions to manage access to data. The development of and transition to the updated platform was informed by a User Acceptance Testing (UAT) that examined the functionality and usability of the platform and associated tools After webinar based orientation UAT, participants were requested to carry out specific tasks using the updated platform and tools in development. This presentation will discuss the objectives and methods of implementation of the UAT, findings from the UAT, and how these guided transition activities and the refinement of the platform applications.A quantitative and qualitative assessment of user support provided by the NSSP Service Desk – H. Tesfamichael, S. Romano A principal component of NSSP is the BioSense platform that includes health care visits related information, particularly related to emergency department visits, from across the U.S. BioSense and its associated tools, including ESSENCE, the Access Management Center, and Adminer, enable state and local health departments, and other, as appropriate, to use syndromic surveillance data to implement surveillance and assessment activities. The NSSP Service Desk provides technical support to BioSense users to assist with the use of the BioSense platform and its tools Users submit support request tickets through an online application. An analysis of information related to these tickets, including the context of the requests and their resolution status, was conducted to better understand the support needs of users and how well these were being addressed. This presentation will discuss the assessment, findings, and conclusions.How the Moderator Intends to Engage the Audience in Discussions on the TopicThe moderator will introduce the session and the panelists.
