The Power of Longitudinal Workforce Intelligence.
Track the Past. Analyze the Present. Predict the Future of Healthcare.
The Challenge
A single snapshot of your workforce isn't enough to inform long-term policy. To understand the true impact of market shifts, economic changes, or new legislation, you need to see the trajectory.
The Solution
Since 2008, NCAHD has maintained a proprietary longitudinal dataset of 15 different healthcare provider types. This 15+ year historical record allows us to perform trend analyses that no other research center in the United States can replicate.
Seeing the Big Picture:
Our Trend Analysis Capabilities
While others look at data points, we look at movement. Our Enhanced State Licensure (ESL) data provides the foundation for deep-dive historical studies.
1. Supply & Demand Evolution
Watch the growth or decline of specific specialties over time relative to population shifts.
2. Alumni Career Trajectories
Combine your historical alumni lists with our 15-year database to see how your graduates’ practice patterns have evolved over their entire careers.
3. Longitudinal Migration
Where did your providers come from, and where are they heading? We track individual-level movement across a decade and a half.
4. Scope of Practice Legislation
How did a change in state law actually affect provider behavior? We analyze the "before and after" of legislative shifts to provide evidence-based results.
The NCAHD Unfair Advantage
Historical Depth
Our records go back to 2008, providing a level of "before and after" context that "point-in-time" datasets simply lack.
Provider-Level Granularity
We don’t just look at aggregate numbers; we analyze individual provider movement across 15 different specialties.
Unrivaled Capacity
We are currently the only research center in the U.S. with the infrastructure to perform this specific level of provider-level longitudinal analysis.
Visualizing the Evolution
Trend analysis is best understood through movement. Our reports include a series of comparative maps that show exactly how your workforce has shifted geographically and demographically over time.
