Shared decision-making is a collaborative process in which clinicians and patients combine the best available evidence with the patient’s values, goals and circumstances to choose among reasonable healthcare options.
It matters most when more than one medically reasonable path exists and the trade-offs are valued differently by different people.
Shared Decision-Making Is Not Simply Giving the Patient a Menu
The clinician contributes evidence, professional judgement, explanation of alternatives and safety boundaries. The patient contributes goals, preferences, lived experience and what burdens or outcomes matter most.
First Establish That the Options Are Reasonable
Shared decision-making does not make every imaginable intervention medically appropriate. Clinical indication, evidence, safety and professional standards still define the set of reasonable choices.
Then Make the Trade-Offs Visible
Useful discussion may include expected benefit, possible harm, uncertainty, recovery time, monitoring burden, effect on daily life and what may happen without treatment.
Absolute Effects Help People Understand Choices
Where possible, communicating baseline risk and absolute benefit can make trade-offs clearer than relative percentages alone.

Patient Values Can Change the Preferred Option
One person may prioritise maximum disease control despite treatment burden. Another may prioritise function, independence or avoiding a particular adverse effect. When both options are medically reasonable, these differences can legitimately lead to different decisions.
Shared Decision-Making and Consent Are Related but Not Identical
Consent establishes whether care is appropriately authorised. Shared decision-making is the collaborative process that can help determine which reasonable option the person wants.
Uncertainty Should Be Shared Honestly
Patients cannot weigh options meaningfully if uncertain benefits or harms are presented as guaranteed outcomes. Good communication makes the limits of knowledge visible without abandoning professional guidance.
See What Is Clinical Uncertainty?.
Some Decisions Have Less Room for Preference
When one option is clearly superior, an intervention is unsafe, or emergency circumstances sharply constrain time, the shape of the decision changes. Shared decision-making does not require artificial equivalence between options.
Decisions Can Be Revisited
New evidence, treatment response, changing goals or changing health state can justify revisiting an earlier choice. Shared decision-making therefore fits naturally into longitudinal care.
The Shared Decision Loop
define the decision → identify reasonable options → explain benefits, harms and uncertainty → understand patient goals → choose → monitor → revisit if the state changes.
