Welcome to the Ohio Pregnancy Assessment Survey (OPAS) Series Dashboard
This interactive tool provides a data-driven view of the health of women in Ohio. You can select data to analyze, examine trends and compare key populations. The dashboard provides fast, real-time results, giving you plots and tables you can insert into documents and presentations. You can use it without having to know any programming or statistical techniques.
Dashboard Overview
This dashboard includes two tabs that allow for a variety of different analysis. Please see below for a short overview of each.
- Trend Over Multiple Years : Produces estimates for an outcome over multiple years, including trend plots and estimate tables
- Single Year Estimates : Produces single year estimates, including bar plots and estimate tables
About the OPAS
The Ohio Pregnancy Assessment Survey (OPAS) Series is administered by the Ohio Department of Children and Youth and the Ohio Department of Medicaid with the assistance of the Ohio Colleges of Medicine Government Resource Center (GRC). The OPAS is a statewide, ongoing, targeted population-based survey that utilizes the Centers for Disease Control and Prevention (CDC) Pregnancy Risk Assessment Monitoring System (PRAMS) methodology to collect information on the experiences and attitudes of current Ohio residents who recently gave birth in Ohio. OPAS is an important surveillance and assessment tool that
- provides data to ODCY and ODH to improve maternal and infant health (MIH);
- allows for the monitoring of changes to specific key MIH indicators in areas such as prenatal care, substance use, breastfeeding, safe sleep for infants, violence, and nutrition;
- enhances ODCY's and ODH's use of birth record data;
- enables a population-based profile of mothers with a live birth; and
- enables comparisons between states relating to maternal and infant health statuses.

Getting Help and Providing Feedback
The Ohio Colleges of Medicine Government Resource Center (GRC) acts as the administrator of the OPAS Dashboards. If this page and the inline help resources do not answer all your questions about the OPAS dashboard, please email the OPAS team at opas@osumc.edu .
Inline Help
The OPAS Dashboard has help icons that provide additional information about the dashboard's components. Click on the question mark buttons next to each component to learn more about what it does. To close, click the button again.
System Requirements
The OPAS Dashboards are optimized for use in recent versions of Mozilla Firefox and Google Chrome on a laptop or desktop screen. Other browsers such as Internet Explorer, older browsers, and mobile devices may not render this application correctly. Additionally, the dashboard's interactive interface depends on JavaScript, which is built into your web browser. However, some organizations disable JavaScript or block certain kinds of content. Check whether JavaScript is enabled in your browser .
Getting Started
- Make selections in the left-hand sidebar.
- Click the Compute Estimates button.
- There are two different options to view the plot - by Percent and by Total .
- There are three different confidence intervals to choose from in the analysis - 90% , 95% and 99% .
- Each time you change your selections, click the Compute Estimates button again to refresh the outputs.
Refining Your Analysis
By default, estimates are created for all Ohioians with a live birth. You can also filter your results to refine your analysis:
- By survey year: Use the provided drop-down or slider to select which year(s) you would like estimates for.
- By county: Selecting from the County Filter menu will provide estimates for only your specified county or county groupings.
Additionally, you can compare results across values of a variable, such as comparing results for different types of insurance coverage, using the compare by drop-down menu.
Remember to click the Compute Estimates button to compute revised estimates based on your selections.
Interpreting Results
Estimated Proportions and Counts
The OPAS is designed to produce estimates that are representative of all Ohioans with a live birth in a given year.
Confidence Intervals
The 'I'-shaped line at the top of each bar or dot represents the confidence interval for the estimate shown. The default confidence level is 90%, but users can choose to instead use confidence levels of 95% or 99%. US Census Bureau page discusses what confidence intervals are and how to interpret them.
Suppression of Unreliable Estimates
When the precision of the estimates is too low, typically because the sample size for the estimate is too small, results are either hidden from view or are replaced with N/A . For an estimate to be displayed, all of the following must be satisfied:
- The numerator of an estimate of a proportion (or estimate of a total) contains responses from 10 or more respondents,
- The denominator of an estimate of a proportion (or subpopulation size of an estimate of a total) contains responses from 30 or more respondents, and
- The coefficient of variation (CV) of survey-weighted estimates is 30% or lower.
Working with the Plots
The trend and bar plots are created using a tool called Plotly . When you hover over a plot, a toolbar appears in the upper-right corner. Feel free to try all the tools on this toolbar to work with your plot, or visit this Plotly guide to learn more.
- The first camera icon in the toolbar allows you to download the plot as a PNG image format.
- Hover over each point estimate in a trend plot, or bar in a bar plot, to get a pop-up displaying more detail about the estimate.
- In addition to using the toolbar, you can double-click the plot to zoom in, or click and drag on a region of the plot to zoom to that region. Double-click again to zoom back out.
Working with the Tables
Each estimate table provides both the estimated proportion (expressed as a percentage) and estimated count, as well as a measure of the associated uncertainty (the confidence interval) for each. Table columns are as follows:
| Column Name | Explanation |
|---|---|
| Estimated Percentage | The survey-weighted estimated percentage of the selected population who have a particular value for the indicator. |
| XX% CI LB Percentage | The lower bound (LB) for the XX% confidence interval (CI) of the estimated percentage. |
| XX% CI UB Percentage | The upper bound (UB) for the XX% confidence interval (CI) of the estimated percentage. |
| Estimated Total | The survey-weighted estimated total in the selected population who have a particular value for the indicator. |
| XX% CI LB Total | The lower bound (LB) for the XX% confidence interval (CI) of estimated total. |
| XX% CI UB Total | The upper bound (UB) for the XX% confidence interval (CI) of estimated total. |
See below for additional details on working with the estimate tables on the OPAS Dashboard.
