Sociospatial Approaches to Health: A Social Inequity Case Study (Exide Battery Plant)
Sheila Steinberg (Brandman University)
This case study presentation involves discussion of environmental and social inequities that stemmed from the Exide Battery Recycling Plant’s illicit practices that exposed adjacent communities to lead. On June 10, 2017, the Los Angeles County
Department of Public Health led an unprecedented effort to conduct a door-to-door community outreach event to 21,000 households to gather information from residents about their health concerns and need, provide educational materials, and help connect residents with health-related services. A sociospatial grounded theory approach is utilized, beginning with observation and working toward creating action-oriented policy to highlight lessons learned. As a team, lessons learned and future educational opportunities are explored for future community outreach and engagement on issues faced by similar communities in other geographic locales. This case study demonstrates how sociospatial grounded theory can be used as a model for future health outreach education and action to preserve and improve people’s health in underserved communities.

Survey123 and sampling Washington School Water for Lead
Lillian Morris (Washington State Department of Health)
Lead exposure in children can cause harmful effects including lower IQ levels, reduced attention span, and hyperactivity. A potential source of lead exposure is drinking water, and the Washington state legislature directed the department of health to test for lead in drinking water in public schools. Staff visit schools and sample water following the EPA’s 3Ts for Reducing Lead in Drinking Water in Schools. The samples are sent to the Public Health Lab for analysis. We have visited ~246 schools and collected an average of ~40 samples per school. We transitioned from pen and paper data collection to Survey123 after the first few months of the program. Test results from the lab are joined to the Survey123 generated report and shared with schools and the public. Approximately 97% of schools had samples with lead concentrations >=1 ppb and ~44% of schools had
samples >=20 ppb (EPA action level). Remediation recommendations specific to the lead concentration are provided to schools with samples >=2 ppb. Transitioning to Survey123 improved the accuracy, efficiency and standardization of field data collection and streamlined our process for communicating results to schools and the public.

Identifying Social, Demographic, and Health System Determinants of Population Health Status, Studying their Relationship with the Use of EMS
Guillaume Cassourret (French Defense Health Service & Val-de-Grace Medical School, Paris, France)
The use of Emergency Medical Services (EMS) has globally progressively increased. However, accessing care through the Emergency Room may not be the more effective way to be provided high quality and patient centered care, despite guaranteeing an equitable access to care.
We mapped and analyzed Basic and Advanced Life Support interventions in Paris and its suburbs in 2016 (n= 303,344 EMS interventions ). We compared the data to population characteristics such as density, poverty level, unemployment rate per geographic unit, and to health system characteristics such as general practitioner density.
We found social and demographic determinants significantly associated with an increase in the use of EMS and ER : Population living in areas with high poverty, high unemployment or low income. Specifically, those determinants were associated with an increase in calls for laboring women, poverty level showed correlations with respiratory diseases, and unemployment rate with intervention for psychiatric complaint.
At a more global level, targeted public health interventions could address the identified risk factors of population vulnerability.

Mapping Dental Deserts: Oral Health Equity in Los Angeles County
Aya Obara (Los Angeles County Department of Public Health, Oral Health Program)
In 2015, Los Angeles County (LAC) Department of Public Health's Oral Health Program (OHP) identified 50 square miles of greater oral health need, or Dental Deserts (DD), in the LAC safety net. Upon receiving data on publicly funded clinics providing dental services in 2017, the primary objective was to update the OHP’s spatial understanding of the current oral health needs landscape.
A geodatabase was created including the following feature classes: publicly funded clinics offering dental services, average number of full-time exempt (FTE) dentists at each clinic funded by LA Department of Health Services (DHS), and 2016 census block group demographic data. LAC DD were created by spatially joining layers to filter for areas with: lower than $30,000 median annual household income (Medi-Cal eligible for family of 4), population of more than 10,000 residents per square mile, and square miles of LAC with no clinics offering dental services. The renewed mapping tool showed that there were 30 noncontinuous square miles designated as DD in 2017. Clusters of DD persist to trend within South Central LAC, in the same LAC areas from years prior, despite receiving more granular data for 2017.

Keeping Military Health Ready for the Battlefield
Andrew Furne (Navy and Marine Corps Public Health Center)
Military Health System (MHS) providers deliver life-saving care on the battlefield. However, trauma skills maintenance can be difficult during peacetime. We provided MHS leadership with location-based analytics to address this dilemma with more informed decisions and opportunities for cost savings. We used GIS to visualize three opportunities: 1. Recapture post-acute trauma care to reduce costs of continuing care. 2. Designate a military hospital as a trauma center in a low access area. 3. Partner with civilian trauma centers to maintain surgical staff skills. Each situation presented challenges in determining requirements, acquiring data, and visualizing results. We employed varied cartographic techniques to portray information in static maps for inclusion in PPT, and also used dynamic, interactive web maps in ArcGIS Online. These multi-faceted solutions increased: 1. Cost savings and caseloads for Navy providers. 2. Access to time-sensitive care in an under served area. 3. MHS leadership’s ability to establish strategic partnerships for keeping military health ready for the battlefield.

|Aligning Access with Population Need
||Providing access to healthcare, public health programs and human services is a critical step to improving health equity. The specific use case of health plans, accountable care organizations, and similar types of health services companies who have an obligation to provide critical health coverage for millions of people will be reviewed. Access to these services is key to helping people stay healthy, avoiding more costly care, and achieving the best possible health for all. Measuring and reporting network coverage serves an intended purpose -- identifying barriers to services, recognizing opportunities for improving access, and knowing what can be done to reduce disparities. The objective of this workshop is to share how ArcGIS Pro, Network Analyst, StreetMap Premium, and Esri data can be used to identify who is likely to experience significant barriers to needed services, detect critical gaps in service coverage, determine how best to fill them, and understand where to focus quality improvement efforts.

West Nile Virus Surveillance: Using GIS as a Tool to Inform and Protect Riverside County Residents
Amy Hyong (RUHS-Public Health)
West Nile Virus (WNV) is a vector-borne viral infection most commonly spread by mosquitoes. Purpose: To provide Riverside County residents with a spatial understanding of the risk of WNV in their area and what treatment efforts are being made to mitigate the risk of the spread of vector borne illness. Methods: A GIS application, publicly launched in 2015, was used to map human cases, surveillance, and treatment efforts. Confirmed WNV human cases were mapped weekly with a buffered radius to ensure confidentiality. Surveillance sentinel, arthropod, and carcass data reported by each vector control district were accessed and mapped using coordinate location data. Treatment was mapped using coordinate data provided by each respective vector control district. Results: Using a GIS web application, side by side maps on human cases, surveillance, and treatment with simultaneous zooming capabilities allowed all three maps to pan to the same location/scale to compare areas of risk with active treatment measures implemented in these areas of risk. These maps were made publicly available to Riverside County residents in 2015, through the Riverside County Public Health website.

Measuring Geographic Distribution of Tularemia Cases in Country of Georgia
Irma Burjanadze (National Center for Disease Control and Public Health)
Tularemia, a zoonotic disease caused by Francisella tularensis is broadly distributed across the northern hemisphere. For the 70 years it has re-emerged several times as sporadic human cases and as large outbreaks in different regions of Georgia. Samples collected from the various vectors during the 2013-2016 fieldwork were mapped in ArcGIS to compare mean center (MC) for Tularemia cases and percentage (TCP) to those for directional distribution (DD). Two main regions with naturally occurring foci of tularemia have been identified. Due to the spread of positive cases by geographic area, standard deviational ellipse that helps understand the spread of Tularemia positive cases is centrally located between those two regions and DD for Tularemia percentages are close to region with high percentage. MC that identifies the geographic center for field values are located in the region where the TCP are higher. Findings indicate that the MC is computed for TCP in order to identify the possible origin for an epidemic, and the DD created elliptical polygon is centered on the MC for all TCP and gives a sense of the orientation by drawing the features on a map.

Using Geographic Information Systems for Public Health Interventions in Nigeria
Nnamdi Usifoh (AFENET)
GIS has been used to manage outbreaks and track the performance of key Routine Immunization indicators. We described how GIS was used during the cholera and cerebrospinal meningitis outbreaks in Nigeria and visualize the monthly Penta3 coverage Methods: We used established geocodes of states and local government areas (LGAs) and epidemiological week of onset to describe the outbreaks. We generate maps showing the monthly immunization coverage of Penta 3 for all 774 LGAs in the country from the DHIS2 platform. Results: The cholera outbreak in 2010 started frrom Borno State and spread to 18 States. The cerebrospinal meningitis outbreak in 2017 started from a few LGAs and spread to contiguous LGAs in the North-west. By depicting the monthly Penta 3 coverage for all LGAs, we determine if there’s an increase or decrease in the monthly immunization coverages per LGA . Conclusion: We successfully used GIS to show how timely detection and effective response could have prevented further spread of diseases. We have also successfully depicted the monthly Penta 3 coverage to the key RI stakeholders in the country, thus eliciting the necessary public health response.

Assessing Homelessness in Sutter and Yuba Counties, CA with ArcGIS
Robert Herrick (Sutter County Health Department)
HUD requires annual sheltered and biannual unsheltered homeless point-in-time (PIT) counts. Paper surveys are slow, time and resource intensive, and collect minimal data. We piloted Survey123 for the 2018 PIT count to assess electronic data collection feasibility.
We configured the Survey123 Homeless PIT Count XLSForm, creating dynamic question text to personalize the interview, link individuals by household, and use answers in follow-up probes.
We surveyed 292 individuals in 132 households at 7 shelters. Average survey length was 20 minutes/household (13 minutes/person). We reduced data entry by 45%, saving 22 manhours, decreased the number of estimated households by 105, and sped up data analysis. Surveyers found electronic data collection easier and faster than paper.
Electronic data collection is feasible for 2019. With Survey123 and ArcGIS Online, we anticipate reducing time to results by 1.5 months, greatly improving location identification, connection to services and our understanding of people experiencing homelessness. Using Survey123 to create dynamic questions is useful for anyone that needs to conduct a census of people experiencing homelessness in their jurisdiction.

Getting Ahead of Opioid Epidemic Utilizing Insights for ArcGIS
Parisa Bozorgi (DHEC)
The need for timely data has increased to evaluate the state response to opioid crises. To identify emerging patterns in drug overdose morbidity and mortality, we developed a dashboard to track opioid prescription metrics and opioid-related health outcomes through the use of a data visualization tool called Esri's Insights for ArcGIS. This spatial analytic tool helps improve state surveillance and dissemination of disparate data sets. The purpose of the Opioid Dashboard will be to provide statewide opioid statistics to public health professionals at the state and national level to curb the epidemic of prescription drug overdoses. Specifically, the dashboard enables users to access timely information including opioid prescription, overdose death, and hospitalization. To better define a dramatic opioid crisis, we used the statistical capabilities of Insights to examine the correlation between drug subtypes and Schedules.
This tool is a more effective way of conveying a set of information to stakeholders and to the public than many traditional static data tables and maps. This kind of information sharing can be the start of solving big challenges like a widespread opioid addiction.
