The NEMSIS V3 Public Performance Measure Dashboard visualizes EMS performance measures defined by the EMS Compass initiative. More information about EMS Compass is available at nasemso.org/projects/ems-compass. Information about the successor to EMS Compass, the National EMS Quality Alliance (NEMSQA), is available at nemsqa.org. The dashboard does not implement all EMS Compass performance measures. Most EMS Compass performance measures are based on NEMSIS data elements, but some measures use data elements that are not available in the national EMS database. The V3 Public Performance Measure Dashboard implements the EMS Compass performance measures that can be measured using data available in the national EMS database ("national" elements).
The NEMSIS V3 Public Performance Measure Dashboard gives the public a way to track the performance of EMS over time and across various EMS agency and incident attributes.
Global Inclusion Criteria and Filters
The NEMSIS V3 Performance Measure Dashboard uses NEMSIS version 3 data only. The past two calendar years, plus the current calendar year, are available (based on eTimes.03 Unit Notified by Dispatch Date/Time).
Each performance measure has its own inclusion criteria, described here: V3 Performance Measures.
Elements of the Dashboard
This dashboard is divided into five sections: Data Set Size, Performance Trend, Geography, Urbanicity, Organization Status, Organizational Type, Agency Annual Patient Contact Volume, and Level of Care.
Data Set Size
The data set size section is designed to be a road map to help navigate this subset of EMS activations. As the user makes selections and filters on the data, the data set size bars will adjust to show how much of the data set is represented in a selection. As an example, if a user were to select the "Seizure-01 Blood Glucose Evaluation" performance measure, which only includes epileptic seizure patients, a relatively small number of EMS activations is included, compared to "Trauma-01 Pain Assessment of Injured Patients," which includes all patients with a possible injury.
Select a Performance Measure
The performance measure selector allows a user to select an EMS Compass performance measure to analyze. When a performance measure is selected, the dashboard displays an overall performance rating using all available data for that measure.
The NEMSIS TAC is implementing the EMS Compass performance measures one-by-one, so more performance measures will become available over time. Please see the following page for detailed documentation of each performance measure:
The Performance Trend section shows change in performance over time, using eTimes.03 Unit Notified by Dispatch Date/Time. Hover over a point on the trend line to see details for the performance for a particular month. Click on a year at the top of the chart to filter the dashboard to that year, or click on a point on the trend line to filter the dashboard to a particular month. Click again to remove the filter.
The Geography section shows relative performance by US Census region, using dAgency.04 EMS Agency State. To drill down to US Census divisions, hover over the region labels and click the "+" that appears in the top left corner. Hover over a bar on the chart to see details for the performance for a particular region or division. Click on a bar to filter the dashboard, and click again to remove the filter. Documentation about the US Census regions and divisions is available here.
The Urbanicity section shows relative performance by USDA urban/rural designations, using eScene.19 Incident ZIP Code. Hover over a bar on the chart to see details for the performance for a particular urbanicity category. Click on a bar to filter the dashboard, and click again to remove the filter. Documentation about the method used to calculate urbanicity is available here.
The Organization Status section shows relative performance by agency volunteer/non-volunteer status, using dAgency.12 Organization Status. Hover over a bar of the chart to see details for the performance for a particular organization status category. Click on a bar to filter the dashboard, and click again to remove the filter.
The Organizational Type section shows relative performance by agency organizational type (fire-based, hospital-based, etc.), using dAgency.13 Organizational Type. Hover over a bar of the chart to see details for the performance for a particular organizational type category. Click on a bar to filter the dashboard, and click again to remove the filter.
Data for the "Tribal" organizational type is suppressed due to differences in US federal government authority related to tribes as opposed to states and territories.
Agency Annual Patient Contact Volume
The Agency Annual Patient Contact Volume section shows relative performance by agency size, based on the annual number of patient encounters submitted to the national EMS database for each EMS agency. Hover over a bar of the chart to see details for the performance for a particular organizational type category. Click on a bar to filter the dashboard, and click again to remove the filter. Agency Annual Patient Contact Volume is not based on dAgency.21 EMS Patient Contact Volume per Year, which is proposed for demotion from "national" element status in NEMSIS 3.5.0. For each agency, Agency Annual Patient Contact Volume is calculated by counting the number of activations in the national EMS database meeting the following criteria:
- eTimes.03 Unit Notified by Dispatch Date/Time is in the year prior to today’s date minus three months (i.e., until the end of March 2019, the calculation is based on counting activations that occurred in 2017; then beginning in April 2019, it is based on activations that occurred in 2018)
- eDisposition.12 Incident/Patient Disposition begins with “Patient”
For each agency, after the count is obtained, it is categorized into one of the following ranges: 1-100; 101–1,000; 1,001–10,000; 10,001–50,000; or Over 50,000. If an agency has no patient contact activations in the previous year, it is assigned to the category labeled "Not Recorded".
Level of Care
The Level of Care section shows relative performance by the level of care provided on each activation, using eResponse.15 Level of Care of This Unit. Hover over a bar of the chart to see details for the performance for a particular organizational type category. Click on a bar to filter the dashboard, and click again to remove the filter. Level of Care is categorized as follows:
|BLS||All Level of Care values that begin with "BLS"|
|ALS (except Nurse, Physician)||Level of Care values that begin with "ALS", except "ALS-Nurse", "ALS-Physician", and "Specialty Critical Care"|
|ALS-Nurse, ALS-Physician, Specialty Critical Care||"ALS-Nurse", "ALS-Physician", and "Specialty Critical Care"|
All Tableau dashboards share the same toolbar at the bottom of the view. Note that while most dashboards will have the same selections, some items may differ based on user permissions.
Undo, Redo, Revert, Refresh and Pause
These selections are found on the left side of the Tableau toolbar and can be used to help navigate the dashboard.
Undo will remove the last selection made, if you have used undo to remove a selection, you can then use redo to return to that selection. Revert returns the dashboard to its original view. Refresh will reload the data on the dashboard subject to any selections made. Pause will stop the dashboard from refreshing as you make selections.
As an example, if you want to make a set of complete selections in a dashboard’s filters, you could use these buttons to speed up the process. Normally every time a change is made, the dashboard will refresh. If you select “Pause” however, the dashboard will remain the same no matter how many selections you make. Once you have made all your selections, you can select “Refresh” to reload the dashboard based on those selections.
Subscribe, Custom Views, Edit, Share, and Download
These selections are found on the right side of the Tableau toolbar and can be used to interact with the dashboard in external ways.
The Subscribe button allows users to subscribe to a daily or weekly email that will show a static image of the dashboard as well as a link to the view.
You can select either a particular view (tab) or all the views (tabs) available in the dashboard. Under “Email Subscriptions” you can choose the frequency of emails and in “Subject Line” you can assign the subject for the emails. As a default, the subscription will be assigned to the email address associated with your NEMSIS account.
Custom Views allows users to save any particular set of filters or selections for quick access later. A user can create their view and then name it and save it either for their own personal use or use by anyone with access to this dashboard. Previously saved views will appear in the custom views tab.
Edit will open the dashboard in the web editor for Tableau. Note that this option is not available on all dashboards and will require some knowledge of how to use Tableau to build and edit dashboards.
Share will provide a couple of options for sharing the dashboard with others; specifically an embed code and a regular HTML link. While you can use the link to share the dashboard with others, please keep in mind that many of the NEMSIS dashboards will require a username and password so only those with credentials will be able to access them.
The last option is Download. Clicking on the download button opens up several options to download either the workbook, the data within it, or a static image of the view.
Selecting any one of these file types will produce a download of the requested file. Remember that not all options will be available for all dashboards and views.
