Pregnancy Risk Assessment Monitoring System (PRAMS)
The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing, site-specific, population-based surveillance project of the Centers for Disease Control and Prevention and health departments. It uses a two-part survey to collect data on maternal attitudes and experiences before, during, and shortly after pregnancy. Survey data has been collected since 1987 and covers approximately 81% of all births in the United States. PRAMS data helps researchers investigate emerging issues and identify ways to reduce health problems for birthing people and their babies.
Between 2021 and 2023, ASTHO convened the Linking PRAMS and Clinical Outcomes Data Multi-Jurisdiction Learning Community supporting 12 states as they build capacity to conduct data linkage activities between PRAMS and other maternal and child clinical outcomes data sets. These linked data sets will inform patient-centered outcomes research and clinical quality improvement initiatives in maternal and child health.

Research and Methodology
Don't Wait, Validate: Estimating Population Outcomes with PRAMS Linked Data
Aug. 7, 2023
Linking PRAMS responses with administrative data is incredibly powerful for exploring population factors associated with various outcomes. However, there are challenges involved: sampling structure, differential response, noncoverage, and small sample sizes can introduce bias. Establishing benchmarks to compare against to validate weighted estimates is critical. Unlike many population-based surveys, PRAMS is directly derived from birth records, which provides a unique validation opportunity.
It’s a Weighty Matter: Exploring PRAMS Weights
Oct. 9, 2023
This session focuses on increasing awareness on how PRAMS weights are constructed, how to properly subset data for weighted analyses, and when health department staff should be worried about over/under estimation. The presenters provide thoughts and methods for checking assumptions of subgroup estimations, potential bias risks, and how re-weighting is sometimes used for smaller subpopulation assessments.
Speakers:
- Jared Parrish, PhD, ASTHO Contractor.
- Phil Hastings, PhD, Founder and Principal, Far Harbor.
