Example

Inpatient at fever onset
No
Serious concurrent comorbidity
Yes
Uncontrolled / progressive cancer
No

Result: Talcott group II — outpatient with serious comorbidity (~55% complications).

The tool opens with these values already filled in. Replace them with your own.

What the result means

Group I-III
Inpatient, or outpatient with comorbidity or uncontrolled cancer: higher complication risk (~31-55%).
Group IV
Outpatient, no comorbidity, controlled cancer: low risk (~2%). A risk classification, not a discharge order.

What you enter
