The Book and Model by Kelly Emrick, DHSc, PhD, MBA
The Happy Patient
Measuring and understanding the metrics that move healthcare toward safer, healthier, and happier patients — an interactive tour of all thirteen chapters.
The Measurement Journey
Thirteen chapters, one destination: a happier, healthier patient. The book moves from everyday vital signs, through the Structure–Process–Outcome model that anchors quality science, into the methods, the patient’s own voice, and the economics that make quality sustainable.
Five reading bands
The Donabedian Engine
Avedis Donabedian’s framework is the spine of Chapters 2–7: good structure enables good process, which produces good outcomes. Tap a stage to see the chapters and metric types that live there.

Leading vs. lagging
Structure and process metrics are mostly leading — they move before results do, so they are where improvement work begins. Outcomes are lagging — they confirm whether the work paid off.
Why the order matters
You cannot reliably fix an outcome by staring at it. The engine says: trace a poor outcome back to the process that produced it, and the structure that enabled that process.
Closing the loop
Methods (Ch. 8–10, 12) and the patient’s voice (Ch. 11, 13) wrap the engine — supplying the data, the comparisons, and the economic case that keep it running.
Metric Explorer
All 130 metrics from the book, tagged by Donabedian category, leading/lagging nature, and chapter. Search by name or filter by category.
Metric Calculators
Live tools for the highest-value formulas in the book — the operational vitals (Ch. 1), the mathematical foundations (Ch. 8), and the economic evaluations (Ch. 13). Enter your own numbers; results update as you type.

Benchmarking & Gap Analysis
Chapter 10 turns measurement into improvement by asking a simple question: compared to whom? The radar shows a sample site against peer median and top-decile performance; the bars quantify the gap to top-decile on each measure.

The Patient’s Voice & The Payoff
Every metric in this book ultimately answers to one question: is the patient better off? Chapters 11 and 13 give that question two languages — the patient’s own report (PROMs) and the economics that keep good care sustainable.
The PROM domains
Patient-Reported Outcome Measures capture what instruments and labs cannot: how care feels from the inside — quality of life, pain, well-being, engagement, and the confidence to self-manage.
The value equation
Quality is not free, but neither is poor quality. Readmissions, errors, and avoidable complications carry a price that often dwarfs the cost of preventing them.
