Decision aids built into the record for every preference-sensitive cancer choice

Choices like mastectomy versus lumpectomy, or whether to have chemotherapy after surgery, depend on what matters to the patient. Good decision aids exist but are rarely used; building them into the clinic workflow would change that.

Decision aids improve knowledge, reduce decisional conflict, and often shift choices toward less intensive treatment in randomised trials, yet routine use is rare. Embedding validated aids into the electronic record so that they are triggered at the relevant decision point, pre-populated with the patient's own risk estimates, and documented as part of consent would make shared decision-making the default rather than an add-on.

Hypothesis
Embedding decision aids will increase documented shared decision-making for defined choices from under 30% to above 80% of eligible consultations and reduce decisional regret at six months.
Rationale
Cochrane reviews show consistent benefits; the implementation literature shows that aids used only when clinicians remember them are rarely used at all.
What would test it
A stepped-wedge rollout across eight breast and prostate services measuring use, decisional conflict, treatment choices, and regret.
