Use case: point location of 911 calls

Idea: Use OpenStreetMap data to identify location of 911 calls to closest clinical facility. Demonstrate in certain communities disparity in proximity of healthcare services to emergency events for opioid overdose, heart attacks, strokes, other acute events. Hypothesis is the longer the distance of services leads to poor outcomes within that community.

• Download US OpenStreetMap
• Download/Install GeoServer
• Identify Lat/Lon of clinical facilities - hospitals, Level 1-3 trauma centers, etc via OpenStreetMap
• Use NEMSIS Location data to measure "accessibility" by region or community types
• Use Boston EMS/Cambridge EMS data as demonstration of community access clustering
• Figure out where to put all this information in an OMOP CDM

Thanks for adding some detail @manlik-brownsrdr ! I'm looking forward to dividing your bullets into what we already support and what we want to focus on next.

Figure out where to put all this information in an OMOP CDM

In a GIS meeting earlier today we were starting to talk about the need for this as it specifically pertains to distance data (where distance is the value in which you are interested) as opposed to exposure data for which we now have a recommendation.

I think this will be a great use case for us to come back and work through after the OHDSI symposium and exposure use cases are more squared away.

Hi,

I am thinking in terms of distance as well in this use case - using the 911 location lat/lon and services lat/lon. However, according to my daughter - I can also calculate distance of travel as the true measure of access using these open source maps datasets. To truly generate representative metrics - also include traffic data, congestions during the day/night, etc. These could be fudge factors as I know the date/time of the 911 call and when the paramedics leave the scene and which destination hospital. So fudge factors could be calculated from these know cases if there is enough date/time coverage. Fun stuff.
