1.2.a Why does Shared Decision Making Matter?

There is considerable evidence that engaging in a shared decision making process is beneficial for both clients and providers.  Researchers have found that shared decision making both improves health outcomes and reduces provider stress (1). People perceived they had better recovery from their discomfort or concern, better emotional health 2 months later, and a reduction of about 50% in rates of diagnostic tests and referrals (1). The most important association with good outcomes was the person's perception that all of the people involved had found common ground (1, 2). Providers report a sense of relief from sole responsibility and greater confidence in the care plan when they have engaged in a shared decision making process with people (2).

The health care conversation that is based on a Shared Decision Making model (3, 4):

  • Improves a person’s knowledge
  • Increases a person’s overall engagement and empowerment
  • Expands opportunity for agreement between care provider and person
  • Increases a person’s satisfaction
  • Reduces use of health care services
  • Greatly reduces unnecessary costs
  • Facilitates more appropriate service use (e.g. major surgery versus low-intervention options)
  • Ensures better treatment adherence
  • Augments confidence and coping skills
  • Strengthens health behaviours

Shared decision making is often referred to as a meeting between experts. But there are a variety of definitions of shared decision making. For example, some people relate it to concepts like informed decision making, enhanced autonomy, and mutual participation (2).

We think this definition if shared decision making sums up well the core components of the concept. It is a collaborative process that is person-centred:

Shared decision making is a collaborative process that allows patients and their providers to make health care decisions together, taking into account the best scientific evidence available, as well as the patient’s values and preferences."
