Shared decision making (SDM) is the process where you and your clinician examine the available options together, weigh the evidence, and land on a choice that fits your values and life. The single most useful thing you can do before your next appointment: write down the decision you’re facing, your top two priorities, and one question you want answered. That preparation alone shifts the conversation from passive to collaborative.
According to Montori et al.’s foundational review, SDM rests on three elements: recognizing that a real decision exists, understanding the evidence and all options (including doing nothing), and incorporating your personal values and preferences. The AHRQ SHARE approach builds those elements into a five-step clinical framework used in practices across the United States.
Before your next visit, run through this quick checklist:
- Identify the decision. Name it specifically: “Should I start a statin?” or “Do I need surgery now, or can I try physical therapy first?”
- List your priorities. What matters most to you — avoiding side effects, keeping your schedule, cost, recovery time?
- Write down your questions. At minimum: “What are all my options?” and “What happens if I choose none of them?”

What is shared decision making, exactly?
SDM is a structured, collaborative approach to clinical decisions where both the patient and the clinician contribute information the other cannot supply alone. The clinician brings medical evidence; you bring knowledge of your own life, values, and what trade-offs you can actually live with. Neither party makes the final call unilaterally.
Montori et al. identify three core elements that must all be present for a conversation to qualify as genuine SDM:
- A decision is recognized. The clinician names the choice explicitly rather than defaulting to a single recommendation. Without this step, the conversation never opens.
- Evidence and options are shared. All medically reasonable paths are explained, including risks, benefits, and the option of no intervention. Leaving out “watchful waiting” or “no treatment” is a common failure point.
- Your values and preferences are incorporated. The clinician asks what matters to you, listens to the answer, and lets it shape the recommendation.
A quick note on spelling: style guides, including the Chicago Manual of Style, recommend hyphenating “decision-making” when it functions as a modifier (“a shared decision-making conversation”) and leaving it open as a noun (“shared decision making”). Both forms appear in the literature; the hyphenated version is more common in clinical writing.
Pro Tip: Try naming the decision out loud at the start of the visit: “I understand we need to decide whether to start X or keep monitoring. Is that right?” This one sentence signals that you expect a two-way conversation, not a prescription.
Systematic reviews show that SDM increases patient satisfaction, improves knowledge of options, and aligns care more closely with patient values, though the evidence for consistent improvement in hard health outcomes remains mixed. The practical benefit for individual patients is real: you leave the visit knowing why you made the choice you made, which tends to improve follow-through.
How do SDM frameworks map to what you can say?
Several frameworks describe the same core process in slightly different language. Clinicians may use any of them; knowing the structure helps you recognize when it’s happening and nudge it forward when it isn’t.
AHRQ SHARE (5 steps): Seek your participation, Help you explore and compare options, Assess your values and preferences, Reach a decision together, Evaluate your decision over time.
Three-talk model (NCBI/NICE): Choice talk (the clinician signals options exist), Option talk (options are described in detail), Decision talk (your preferences are elicited and a choice is made). NCBI Bookshelf guidance describes this as an ongoing process rather than a single event.
4-step pediatric framework (AAP): Designed for pediatric settings, this model helps clinicians calibrate how much weight to give physician guidance versus parent or patient preference depending on the type of decision. It’s a useful reminder that SDM looks different across specialties and age groups.
The table below maps each framework step to language you can use to move the conversation forward.
| Framework step | What you can say |
|---|---|
| Seek participation (SHARE step 1) | “I’d like to be involved in this decision. Can we go through my options?” |
| Help explore options (SHARE step 2) | “What are all the medically reasonable choices here, including doing nothing?” |
| Choice talk (three-talk step 1) | “Are there other paths besides the one you’re recommending?” |
| Option talk (three-talk step 2) | “Can you walk me through the risks and benefits of each option?” |
| Assess values (SHARE step 3) | “I want to factor in [side effects / cost / recovery time]. How does that change things?” |
| Reach a decision (SHARE step 4) | “Based on what we’ve discussed, I’m leaning toward X. Does that make sense medically?” |
| Evaluate / Decision talk | “Can we set a follow-up to see if this is still the right call in three months?” |
Most U.S. clinicians trained after 2010 have had some exposure to at least one of these models, though application varies widely. If your clinician jumps straight to a recommendation without naming options, the table above gives you a phrase to redirect without sounding confrontational.
What does a real SDM visit actually look like?
A genuine SDM encounter has a recognizable shape. The clinician opens by naming the decision, not by announcing a plan. They describe at least two options, explain the trade-offs in plain language, and ask what matters to you before landing on a recommendation.
Signs that SDM is happening in your visit:
- The clinician says something like, “There are a few reasonable paths here, and the right one depends partly on what you value most.”
- You’re asked about your daily life, work schedule, or concerns about side effects before a recommendation is made.
- The clinician pauses and checks whether you have questions rather than moving directly to the next item.
- A decision aid, printed summary, or website is offered.
Most SDM conversations in primary care run 10–20 minutes. If you feel the visit moving too fast, it’s entirely appropriate to say: “I want to make sure I understand all my options before we decide. Can we slow down for a minute?” You can also ask for a follow-up call or a second visit specifically to discuss the decision after you’ve had time to think.
If you want a decision aid, ask directly: “Is there a pamphlet or online tool that lays out my options? I’d like to review it before we finalize anything.” Clinicians who practice SDM routinely provide these; those who don’t may need a prompt. For more on structuring the conversation itself, Whendoctorsdontlisten’s guide on doctor-patient communication covers scripts and rights in detail.
What does the evidence say about SDM’s benefits?
Systematic reviews summarized in Health Affairs consistently find that SDM improves patient knowledge of their condition and options, increases satisfaction with care, and produces decisions that better reflect patient values. The evidence for direct improvement in clinical outcomes like mortality or disease progression is more variable, partly because those outcomes depend on many factors beyond the decision-making process itself.
What the research does show reliably:
- Patients who participate in SDM report higher trust in their clinicians.
- SDM reduces the rate of “preference-mismatched” care, meaning patients are less likely to receive treatments they would have declined if fully informed.
- Informed patients tend to adhere better to the treatment they chose, because they chose it.
- SDM is associated with fewer unwanted interventions, particularly in elective and screening contexts.
The mixed signal on hard health outcomes doesn’t undermine the case for SDM. It reflects measurement difficulty more than treatment failure. Whether a patient with early-stage prostate cancer chooses active surveillance or surgery, both are medically defensible. SDM doesn’t determine which is “right” in an absolute sense; it determines which is right for that person. That distinction is where the real value sits.
For patients navigating complex or chronic conditions, the practical payoff is clearer still. A decision made with full information and genuine input is one you can commit to, revisit, and adjust over time without feeling like something was done to you.
Which types of medical decisions usually need SDM?
Not every clinical decision is a candidate for SDM. Some decisions have a single correct answer based on strong evidence, and the clinician’s job is simply to explain it. The decisions that genuinely call for a collaborative process are called preference-sensitive decisions: situations where multiple medically reasonable options exist, where trade-offs are real, or where the right answer depends heavily on what you value.
Common preference-sensitive decision types:
- Screening tests with trade-offs. Mammography in women in their 40s, PSA testing for prostate cancer, and lung cancer screening in smokers all involve real trade-offs between detection benefit and false-positive risk. Your risk tolerance matters.
- Elective surgery vs. conservative management. Knee replacement, back surgery, and hernia repair often have non-surgical alternatives. The “best” choice depends on your pain level, activity goals, and tolerance for surgical risk.
- Chronic disease therapy vs. watchful waiting. Starting a statin, antidepressant, or blood pressure medication when numbers are borderline involves weighing modest population-level benefit against daily pill burden and side effects.
- Preventive interventions with variable net benefit. Aspirin for primary prevention, hormone therapy, and some vaccines in specific populations involve benefit-risk calculations that shift based on individual health history.
- End-of-life and serious illness planning. Decisions about aggressive treatment, palliative care, and advance directives are among the most values-laden decisions a patient can face.
A useful test: if a reasonable clinician could support more than one option, and if your personal priorities would influence the choice, that’s a preference-sensitive decision. Ask for SDM.
How to prepare for an SDM conversation
Preparation is the highest-yield thing you can do. AHRQ’s guidance on patient engagement specifically identifies pre-visit preparation as a key factor in making SDM work under time pressure. A clinician who sees a patient arrive with a written priorities list can convert a rushed 12-minute visit into a productive one.
Pre-visit checklist:
- Name the decision. Write it as a question: “Should I start metformin now or try lifestyle changes for three months first?”
- List your top three priorities. Examples: avoiding weight gain, keeping costs under $50/month, not disrupting your work schedule.
- Note your barriers. Needle phobia, transportation limits, caregiver responsibilities, cost concerns. These are clinically relevant.
- Collect your facts. Current medications, recent lab values, symptom timeline, any prior treatments tried.
- Write two to three questions. At minimum: “What are all my options?” and “What do you recommend and why?”
Scripts for common SDM moments:
Opening the decision talk: “I know we’re here to discuss [X]. Before we decide, can you walk me through all the options, including not treating right now?”
Asking about risks: “What are the most common side effects or downsides of each option? And how likely are they?”
Expressing your priorities: “The thing that matters most to me is [Y]. Does that change which option makes more sense?”
Asking for time: “This is a lot to take in. Can I have a few days to think it over before we finalize anything?”
Citing a source without sounding adversarial: “I read an AHRQ summary that lists these options. Can we go through them together?”
For digital advocacy, bring reputable links or printed summaries from sources like AHRQ or NCBI. Request decision aids through your patient portal before the visit if possible. Whendoctorsdontlisten’s digital advocacy resource covers how to use patient portals and online tools to prepare effectively.
Pro Tip: Practice your opening script aloud before the visit. If your clinician seems rushed, say: “I have a short list of priorities I’d like to share. Can I take 60 seconds?” Most clinicians will say yes, and it resets the pace of the conversation.
Where to find and evaluate decision aids
Decision aids are structured tools, usually a pamphlet, video, or interactive website, that lay out your options, explain the evidence, and help you clarify your values. AHRQ’s implementation resources recommend using them before, during, and between consultations. They work best when embedded in the clinical conversation rather than handed out and forgotten.
Where to find vetted decision aids:
- AHRQ (ahrq.gov): — Offers patient-facing guides and links to decision-aid resources across common conditions.
How to ask your clinician: “Is there a decision aid for this? I’d like to review one before we finalize the plan.”
Quick checklist for evaluating a decision aid’s quality:
| Quality criterion | What to look for |
|---|---|
| Clear explanation of options | All medically reasonable choices are named, including no treatment |
| Balanced harms and benefits | Neither option is presented as obviously superior without evidence |
| Uncertainty is disclosed | The tool acknowledges where evidence is limited or conflicting |
| Authorship and source cited | A named organization, institution, or clinical team is credited |
| Date of last update | Ideally updated within the past three to five years |
A decision aid that presents only one option favorably, omits side effects, or lacks a named author is a red flag. For rare disease scenarios where standard decision aids may not exist, the partner resource on discussing rare disease findings offers practical communication guidance for those conversations.
Common barriers to SDM and how to handle them
The most common obstacles to SDM aren’t dramatic. They’re structural: short visits, clinicians who default to directive communication, and patients who don’t know they’re allowed to ask for more. Health Affairs implementation research identifies time pressure, clinician training gaps, and the absence of decision aids in the workflow as the top barriers.
Barrier → solution pairs:
- Rushed visit: Ask to schedule a longer appointment specifically for the decision, or request a follow-up call. Say: “This feels like a decision that needs more time. Can we schedule 20 minutes to go through it properly?”
- Clinician skips options: Use the scripts above to redirect. “Before we go with that plan, can you tell me what the alternatives are?”
- Medical gaslighting or dismissal: Document your concerns in writing, bring a trusted person to the visit, and consider requesting a second opinion. Whendoctorsdontlisten’s resource on advocating against stereotypes addresses structural bias in clinical encounters directly.
- Low health literacy or complex information: Ask for plain-language explanations. “Can you explain that in everyday terms?” is a completely reasonable request. You can also ask for written materials to review at home.
- Language barrier: You have the right to a qualified medical interpreter under federal law. Request one through the clinic’s front desk before your appointment.
After the visit, use your patient portal to review the visit notes. If the decision and your reasoning aren’t reflected accurately, contact the office to request a correction. That record matters if care becomes fragmented across providers.
For patients facing rare disease diagnoses where standard pathways are unclear, the patient rights guide for rare disease care is a practical companion for navigating those escalation conversations.
Three real-world SDM scenarios
Mammography screening in a woman in her 40s
A 42-year-old woman comes in for a routine visit. Her clinician raises the question of mammography. This is a textbook preference-sensitive decision: major medical organizations disagree on the optimal starting age, and the trade-off between early detection and false-positive rates is real.
- What triggers SDM: No single guideline applies universally; the decision depends on family history, anxiety tolerance, and how the patient weighs a potential false positive against the reassurance of a negative result.
- What the clinician says: “The evidence supports starting anywhere from 40 to 50 depending on your risk factors and preferences. There are real benefits and real downsides to starting earlier.”
- What the patient can ask: “What’s my personal risk level? And what happens if the result comes back unclear?”
- Possible outcomes: She chooses annual screening starting now, opts to wait until 45, or decides to revisit in a year after reviewing a decision aid.
Elective knee replacement vs. physical therapy
A 58-year-old man has moderate osteoarthritis. Surgery would likely reduce pain, but physical therapy can also produce meaningful improvement, and surgical recovery takes months.
- What triggers SDM: Both options are medically reasonable. His activity goals and tolerance for surgical risk are the deciding factors.
- What the patient can ask: “If I do physical therapy for six months and it doesn’t work, is surgery still on the table? And what’s the realistic recovery timeline if I choose surgery now?”
- How values shift the outcome: A patient who travels for work and can’t afford six weeks of recovery will likely weigh the options differently than someone who is retired and prefers to avoid surgery.
Statin therapy for primary prevention
A 55-year-old woman has a 10-year cardiovascular risk score that puts her in a borderline range. Guidelines suggest a conversation, not an automatic prescription.
- What triggers SDM: The absolute risk reduction from a statin at her risk level is modest. Whether that benefit outweighs daily medication, potential muscle side effects, and cost is genuinely a values question.
- What the clinician says: “Your numbers put you in a range where a statin could help, but the benefit isn’t dramatic. Some people in your position choose to start; others prefer lifestyle changes first.”
- What the patient can ask: “How much does a statin actually reduce my risk in absolute terms, not just relative terms?”
- Possible outcomes: She starts a low-dose statin, commits to a 90-day diet and exercise trial with a follow-up lipid panel, or decides to hold off and revisit in a year.

Why patients who ask for SDM get better care
The conventional wisdom is that SDM is something clinicians do to patients, or for them. That framing is wrong, and it’s worth saying plainly. SDM is something you participate in, and the quality of your participation directly affects the outcome.
Clinicians who practice high-quality SDM treat it as a fundamental redesign of the consultation, not an add-on. But even the best clinician can’t deliver SDM to a patient who hasn’t thought about what they want. The preparation steps in this article aren’t bureaucratic box-checking. They’re the mechanism by which your values actually enter the room.
What I find most overlooked in the SDM literature is the emotional dimension. Patients often feel that asking for options or pushing back on a recommendation is somehow rude or adversarial. It isn’t. A clinician who presents one option and expects agreement isn’t practicing medicine at its best. You’re not challenging their expertise when you ask “what are my other choices?” You’re giving them the information they need to help you well.
The scripts in this article are deliberately low-confrontation. They work because they frame your participation as a contribution to the process, not a challenge to authority. Try one at your next visit. The worst outcome is a clinician who answers the question. The best outcome is a decision you actually chose.
Whendoctorsdontlisten has the tools to help you prepare
Most patients leave the doctor’s office unsure whether they made the right call, not because the medicine was wrong, but because no one helped them think through what they actually wanted. That’s the gap Whendoctorsdontlisten was built to close.
The book When Doctors Don’t Listen and its companion website give you longer scripts, downloadable pre-visit checklists, and real case studies drawn from clinical practice, the kind of preparation material that turns a 12-minute appointment into a genuine conversation. Where this article gives you the framework, the book gives you the depth: how to handle a clinician who dismisses your concerns, how to document a decision so it follows you across providers, and how to ask for a second opinion without burning the relationship.
The patient advocacy guide on the site is a strong next step for anyone who wants to go further. And if you’re ready to start with the book itself, visit whendoctorsdontlisten.com to find it through the publisher and linked retailers.
