What's Happening with Sentinel

Addressing Missing Data in Comparative Effectiveness Research Using EHR Data
Event Type: Webinar
Date: Monday, September 26, 2022
Time: 1:00pm - 2:00pm EST

Among the numerous methodological issues researchers encounter when using electronic health record (EHR) data, selection bias due to incomplete/missing data has received relatively little attention. Building on a recently-proposed framework for modularizing the data provenance, we develop a general and scalable framework for estimation and inference with respect to regression models based on inverse-probability weighting that allows for a hierarchy of missingness mechanisms to better align with the complex nature of EHR data.

About Sentinel

The U.S. Food and Drug Administration (FDA) leads the Sentinel Initiative. The main goal is to improve how FDA evaluates the safety and performance of medical products.

How Sentinel Uses Data

The FDA uses Sentinel data to evaluate the safety of medical products. They also use Sentinel data to learn more about potential side effects.

How Sentinel Protects Privacy

Sentinel uses a distributed data approach. In this approach, data remain with the data owner, i.e., an insurance company. Also, data owners remove patient identifiers to protect privacy.

Privacy & Security

Where Sentinel Gets Its Data

Sentinel data come from existing sources. These includes insurance claims, electronic health records, and patient reports.

Who is Involved

What Data Sentinel Uses

Data from the health systems, insurance companies, or medical records can be used without personal information being shared to learn more about medical products.

Recent Webinar: An Overview of Sentinel’s Publicly Available Analytics Tools

The Sentinel Community Building and Outreach Center (CBOC) has developed a webinar series to increase stakeholder awareness and engagement with the Sentinel System. The purpose of this webinar was to provide an understanding of Sentinel's publicly available analytics tools, the Sentinel Common Data Model, and how to access those resources from the Sentinel website. It was held on Wednesday, September 14, 2022.

Data Partners & Collaborators

The FDA gets data for the Sentinel System through its Data Partners. The Data Partners are the ones who access, maintain, and protect the data in a distributed system. The Sentinel Coordinating Center partners with a network of collaborators. This includes Data Partners and Collaborating Institutions. Together, they provide healthcare data and scientific, technical, organizational expertise.

Sentinel Structure

1. Community Building and Outreach Center (CBOC)
2. Innovation Center (IC)
3. Sentinel Operations Center (SOC)

These centers collaborate to advance regulatory science using the Sentinel System. However, each center operates independently and has a dedicated leadership team and staff. The three centers each carry out projects associated with their strategic objectives.
