Objective
Generate and explain the 12-month functional probabilities to support informed consent.
Clinical scenario
The patient wants to know: will I be continent? Will I keep potency? The Trifecta turns the surgical decision into quantified expectations.
Step by step in the app
- 1
Have PRECE calculated
The Trifecta uses the ECE risk, so run PRECE first. Age, PSA and biopsy also need to be filled in.
- 2
Set the Hopkins grade
Select the planned nerve-sparing grade (1–4) for each side.
- 3
Read the three outcomes
12-month potency, 12-month continence and negative margin appear with a confidence interval.
- 4
Check the adjustments
The badges show the applied adjustments (age, ISUP, ECE, bilateral penalty) — full transparency.
- 5
Use it in the consent
Present the numbers to the patient as part of informed consent, making clear that they are probabilities.
Clinical pearls
- Bilateral preservation improves the functional outcome, but the app penalizes it correctly when the oncologic risk rises.
- Showing the confidence interval avoids promising certainties that the statistics do not support.
