In 2025, a year in which the industry continued to expand on the promise and potential of the seismic shift toward value-based care, our most widely read whitepapers focused on analytics driving strategic growth and cost savings. Milliman MedInsight whitepapers have explored everything from the cost and efficacy of specific drugs to the changing patterns in telehealth care delivery.
Here is an overview:
1. Measuring the unseen: Differentiation in health system services
Authors: Rong Yi, Brian Merkey
Theme: The value of measuring and understanding health system service differentiation
In a healthcare landscape marked by growing consolidation as the result of mergers, acquisitions and integrations, understanding the different ways that health systems are organized is critical for health insurers, health systems and regulators.
This whitepaper maps a wide range of data accessible via the MedInsight Provider Registry to measure the ways in which health systems differentiate from each other and internally, with differing characteristics among their own facilities. The results, as the authors show, can be used for insights into market positioning and strategic planning.

2. The importance of clear provider groupings in healthcare service analysis
Authors: Robbie Richards, Brian Merkey
Theme: The importance of clear definitions and a thoughtful approach in conducting provider market share and service concentrations analyses
Historically, provider market share analyses have a tendency to become mired in complicating factors like the endless ways “provider” can be defined and countless options for quantifying what is meant by “share.”
Using an approach codified in the Milliman MedInsight Provider Registry, however, the authors demonstrate how clear definitions and a structured framework that integrates disparate sources in a standardized dataset of healthcare provider information can substantially simplify and improve analysis.

3. Cascading impact of unnecessary or low-value care services
Author: Suman Pattnaik
Theme: How the identification of low-value care prevents a cascading effect that contributes to an estimated $340 billion of unnecessary treatment in the U.S. each year.
Research shows that wasteful healthcare services have a way of compounding the losses by triggering further testing and treatments of doubtful value.
Author Suman Pattnaik shines a spotlight on this cascading effect by using the Milliman MedInsight® Health Waste Calculator to drill down into utilization patterns and costs to analyze cases of cascading events following low-value care.
