Your hospital has data tools. No decision tool.
Entity Flow turns operational data into auditable, defensible decisions — staffing, capacity, service lines — in weeks, not quarters.
Already deployed in hospital systems managing 500+ beds.
Every hospital has the same problem.
Your analysts have the data. Your models make predictions.
But when it's time to decide — how many nurses next quarter, which service line to expand, whether to add weekend OR capacity — the decision still happens in a conference room with slides, gut feel, and no audit trail.
The gap isn't data. It's the last mile: turning analysis into a defensible decision that survives the CFO, the board, and the audit.
Entity Flow closes that gap.
Not a dashboard. A decision engine.
Entity Flow generates scenario-ranked, constraint-aware, auditable decision packages for hospital operations.
Scenario Engine
Model 3–5 staffing or capacity scenarios with real constraints — budget, regulations, union rules, seasonal demand. See trade-offs side by side.
Decision Brief
A 10-page decision document your COO can defend to the board. Recommended action + reasoning + what changes the answer.
What-Changes-My-Mind
The 1-page document that tells you when to revisit this decision. Top 5 conditions that would change the recommendation. No other vendor provides this.
What you get: Decision Brief (10p) + Methods & Assumptions (2–8p) + What-Changes-My-Mind (1p)

No EHR integration required.
Frame
Define the decision. What's the question? What are the constraints? We start with public data + minimal operational inputs.
Model
Build scenarios. Run cost-effectiveness, budget impact, and sensitivity analysis. Rank options by your constraints.
Deliver
Deliver Decision Brief + What-Changes-My-Mind. Your COO has a defensible recommendation. Your board has an audit trail.

No EHR integration needed to start. We work with public data + your existing reports.
Expand data connections only when (and if) it adds decision value.
But when you connect your EHR, this is what happens.
After the first Decision Packet: monthly retainer.
We update the model as conditions change — policy shifts, seasonal demand, staffing changes. Your decision brief stays current.
What we see before the first meeting.
Built from public data alone — no internal files, no EHR access, no NDA. Hover nodes to explore relationships. Yellow edges reveal decision leverage points.
WHERE DECISIONS HIDE
Each node is a public data point. Most hospitals already track them — separately, in different departments, on different dashboards. The yellow edges are what matters: 670 open positions don't just mean “we're hiring” — they predict ED wait time pressure. A 3.6% margin doesn't just mean “tight” — it constrains every staffing decision for the next two years. Entity Flow connects these into auditable decisions, not more dashboards.
All data from publicly available sources. No internal hospital data used. · Entity Flow by Doogooda
A methodology, not a black box.
Entity Flow is built on Decision Science — a structured approach to making defensible choices under uncertainty.
This is what a Decision Brief looks like.
Already deployed. Already working.
4 years of hospital and government deployment. Not a prototype.
Built by people who've done this before.
