Shared Decision-Making When Medicine Has No Easy Answers
In a world of complex choices, the most powerful medical tool is often a conversation.
Imagine sitting in a doctor's office, facing a treatment decision where even the experts cannot predict the perfect path forward. The data is conflicting, the outcomes uncertain, and the stakes are high. This scenario is not an exception in modern medicine—it's the rule.
Medical uncertainty arises from various sources: incomplete evidence, individual variations in treatment response, and the challenge of applying population-based research to a single person. In this landscape, shared decision-making has emerged as a vital process that honors both medical evidence and patient values. It represents a fundamental shift from the traditional paternalistic model toward a collaborative approach where patients and clinicians navigate complex choices together 1 2 .
Shared decision-making (SDM) is a collaborative process where patients and healthcare providers deliberate together based on shared evidence, working through options while informed by the patient's unique values, preferences, and circumstances 1 2 . This approach rests on an ethical foundation of respect for patient autonomy and recognition that medical decisions involve not just biological outcomes but personal values and life priorities.
The process becomes particularly crucial in "preference-sensitive" decisions—situations where multiple reasonable options exist, and the "best" choice depends heavily on what matters most to the patient 3 . For instance, one person might prioritize longevity despite treatment side effects, while another values quality of life above all else.
As one researcher notes, "Medicine's ground state is uncertainty" 6 . This uncertainty manifests in several dimensions:
Medical training has traditionally emphasized certainty and definitive answers, yet clinicians increasingly recognize that tolerating ambiguity is an essential skill for modern practice 6 . One study found that physicians with low tolerance for ambiguity ordered more tests and reported higher burnout levels—highlighting the very real consequences of how we handle uncertainty 6 .
When facing uncertain medical decisions, clinicians and patients can draw from a set of core communication and ethical principles that form a practical "toolbox" for these challenging conversations 2 :
| Principle | Definition | Clinical Example |
|---|---|---|
| Honesty | Acknowledging limitations of evidence and genuine uncertainty | "Whether statins should be used for primary prevention in your situation is a matter of professional dispute." 2 |
| Recognition of Emotion | Explicitly acknowledging the emotional dimensions of decisions | "I sense you're anxious about the cancer possibility, which might understandably influence your screening choice." 2 |
| Hope | Maintaining space for positive outcomes while being truthful | "While we can't predict the exact course of your arthritis, many people maintain active lives with today's treatments." 2 |
| Support & Care Coordination | Ensuring clear responsibility amid specialist involvement | "If we consult surgery, let's establish who will coordinate your ongoing care." 2 |
| Willingness to Readdress | Recognizing that decisions can evolve with new information | "Let's try this approach for 3 months and reassess how it's working for you." 2 |
These principles share a common thread: they acknowledge that uncertainty cannot always be eliminated but must be consciously addressed and managed 2 . This represents a significant shift from traditional medical communication that often downplayed uncertainty.
A persistent misconception has limited the implementation of shared decision-making: the idea that it only applies when clinical "equipoise" exists—when different options have nearly identical medical outcomes 4 . Recent thinking challenges this narrow view.
Equipoise is neither necessary nor sufficient for determining when shared decision-making should occur 4 . In practice, patients and clinicians may perceive options differently—a family might see meaningful trade-offs where a clinician sees one clearly superior medical choice. The emerging consensus suggests that SDM should be used whenever patients' values, preferences, and contexts might influence the desirability of different approaches 4 .
| Form of SDM | Problem Type | Goal of Conversation | Clinical Example |
|---|---|---|---|
| Matching Preferences | Clear options with uncertain preferences | Match option features with patient values | Choosing between diabetes medications with different side effect profiles 8 |
| Reconciling Conflicts | Internal or external conflicts | Resolve tension between competing values or viewpoints | Deciding about driving cessation for an older adult with cognitive changes 8 |
| Problem-Solving | Practical implementation challenges | Develop workable solutions to complex situations | Determining safe discharge planning from hospital to home 8 |
| Meaning Making | Existential dimensions of illness | Find personal significance and reasons for action | Planning end-of-life transitions or gender-affirming therapies 8 |
Despite widespread endorsement of shared decision-making, implementation in clinical practice remains limited. A recent mixed-methods study conducted across seven Dutch teaching hospitals sought to understand why by examining the attitudes, beliefs, and behaviors of both residents and medical specialists regarding SDM .
The researchers employed a sequential mixed-methods approach :
315 physicians (127 residents and 188 medical specialists) completed validated questionnaires measuring their attitudes toward and self-reported use of shared decision-making.
Researchers conducted in-depth focus group interviews using a semi-structured guide to explore emerging themes from the survey data. The interviews were transcribed and analyzed using both deductive (theory-driven) and inductive (data-driven) coding approaches.
The study revealed a striking disconnect between physicians' stated values and their actual practice :
The most significant finding emerged from thematic analysis of the focus groups: disease-centered beliefs represented the primary barrier to implementing shared decision-making . Both residents and specialists demonstrated patterns of thinking that prioritized disease pathology over person-centered considerations, unconsciously influencing their decision-making processes.
This study provided crucial insight into why decades of promoting shared decision-making has shown limited success. The researchers concluded that sustainable implementation requires more than skills training—it demands a fundamental paradigm shift from disease-centered to person-centered thinking .
This work highlights that changing SDM practice requires addressing deeply embedded cognitive frameworks rather than simply teaching communication techniques. It also explains why many previous interventions have failed to produce lasting change—they treated SDM as another clinical skill to master rather than a different way of conceptualizing the patient-clinician relationship.
For researchers investigating shared decision-making in uncertain conditions, several validated frameworks and tools enable rigorous study of this complex process:
| Resource | Type | Function | Source |
|---|---|---|---|
| Three-Talk Model | Conceptual Framework | Describes 3 key steps: Team Talk, Option Talk, Decision Talk 5 | Elwyn et al. |
| SHARE Approach | Implementation Model | Mnemonic for 5 steps: Seek, Help, Assess, Reach, Evaluate 5 | AHRQ |
| Purposeful SDM | Analytical Framework | Identifies 4 deliberative processes: matching preferences, reconciling conflicts, problem-solving, meaning making 5 8 | Hargraves et al. |
| IP-SDM Model | Comprehensive Model | Expands beyond patient-clinician dyad to include interprofessional teams and family 7 | Legaré et al. |
| Control Preference Scale | Measurement Tool | Assesses patient and clinician preferences for decision-making roles | Degner et al. |
As we move toward a more collaborative healthcare culture, shared decision-making is increasingly understood not as "another thing clinicians must do" but as a fundamental method of care 8 . This perspective integrates SDM into the essential fabric of clinical practice alongside history-taking, examination, and treatment planning.
"Wisdom—for both patients and doctors—is defined by how one copes with" medical uncertainty 6 .
The future of shared decision-making depends less on debating when it applies and more on learning how to do it well across diverse clinical contexts 4 . This will require developing adaptable skills, creating supportive systems, and fostering awareness of the unconscious beliefs that shape our decision-making patterns .
In the end, shared decision-making in the face of uncertainty acknowledges that while clinicians bring medical expertise to the encounter, patients bring something equally important: expertise about their own lives, values, and priorities. The wisest path forward often emerges when these two domains of knowledge meet in honest conversation.
Through shared decision-making, patients and clinicians don't eliminate uncertainty but learn to navigate it together, making choices that honor both evidence and what makes life meaningful.
