The SPR Research Assemblies are designed to present innovating, state of the art research that is cross-disciplinary and not focused on a single clinical specialty. This session will bring together four featured platform speakers (selected from high-scoring abstracts submitted to PAS 2025, and prioritizing early career investigators) with one invited speaker, who will be an established investigator in the field of health services research. This session will have two major goals. First, to facilitate connections between researchers untied by a thematic research focus, who would normally be delegated to different PAS sessions. Second, to feature high impact/cutting edge health services research projects that complement an invited speaker presentation.

Learning Objectives:

1. Identify approaches and barriers to conducting health services research in pediatrics.
2. Understand how collaboration and information exchange across specialties could result in more impactful discoveries.
3. Describe cutting-edge methodologies that allows the study of large populations in pediatric health services research.

Presentations:

7:00am – 7:03am HST
