Patient shared decision making
Under a shared decision making (SDM) process, health care practitioners and patients work together to make joint decisions about a patient’s care, informed by the patient’s preferences and values. SDM requires that patients be educated about and understand the risks and benefits of their options; education is often through decision aids such as pamphlets, videos, and computerized tools. SDM is an important part of patient-centered care (Légaré F, Ratté S, Stacey D, et al. Interventions for improving the adoption of shared decision making by healthcare professionals. Cochrane Database of Systematic Reviews. 2014;(5):CD006732.

Using probabilities in decision aids, especially expressed in numbers, improves the accuracy of the level of risk patients perceive (Stacey D, Légaré F, Col NF, et al. Decision aids for people facing health treatment or screening decisions. Cochrane Database of Systematic Reviews. 2017;(1):CD001431.
Link to original source (journal subscription may be required for access)Cochrane-Stacey 2017). Computerized aids appear as effective as aids delivered in person (Sheehan J, Sherman KA.

SDM has been shown to be particularly effective for patients making long-term decisions, patients with chronic health problems (Joosten EAG, DeFuentes-Merillas L, de Weert GH, et al.

Availability of patient decision aids for stroke prevention in atrial fibrillation: A systematic review. American Heart Journal. 2017;191:1-11.

SDM can also increase knowledge regarding colorectal cancer screening (Volk RJ, Linder SK, Lopez-Olivo MA, et al.

Link to original source (journal subscription may be required for access)Dugas 2012). Allowing time to build rapport and trust with providers using SDM may improve patients’ mental health (Légaré F, Ratté S, Stacey D, et al.

Use of decision aids has been shown to reduce the frequency of prostate-specific antigen (PSA) screening, major elective surgeries (Stacey D, Légaré F, Col NF, et al. Decision aids for people facing health treatment or screening decisions. Cochrane Database of Systematic Reviews. 2017;(1):CD001431.

SDM may improve asthma management and increase satisfaction for asthmatic patients and their parents (Kew KM, Malik P, Aniruddhan K, Normansell R. Shared decision-making for people with asthma. Cochrane Database of Systematic Reviews. 2017;(10):CD012330.
Link to original source (journal subscription may be required for access)Cochrane-Kew 2017). SDM also appears to improve quality of life for patients during cancer treatment (Kashaf MS, McGill E.

Link to original source (journal subscription may be required for access)Kashaf 2015) and can increase patient satisfaction overall (Shay LA, Lafata JE. Where is the evidence? A systematic review of shared decision making and patient outcomes. Medical Decision Making. 2015;35(1):114-131.
Link to original source (journal subscription may be required for access)Shay 2015).
SDM has been shown to improve patient-provider communication for racial and ethnic minorities (Nathan 2016, Mead EL, Doorenbos AZ, Javid SH, et al. Shared decision-making for cancer care among racial and ethnic minorities: A systematic review. American Journal of Public Health. 2013;103(12):e15-e29.
Link to original source (journal subscription may be required for access)Mead 2013). Individuals with low incomes or low literacy levels appear to benefit more from SDM than peers with higher incomes or levels of education (Durand 2014). Educational meetings, feedback, learning materials, and decision aids (Légaré F, Ratté S, Stacey D, et al. Interventions for improving the adoption of shared decision making by healthcare professionals. Cochrane Database of Systematic Reviews. 2014;(5):CD006732.
Link to original source (journal subscription may be required for access)Cochrane-Legare 2014), along with policies to support use, may help health care providers adopt SDM (Williams N, Fleming C, Doubleday A.

The impact of patient shared decision making on health care costs is unclear. Some studies show lower costs or no additional costs (Stacey D, Légaré F, Col NF, et al. Decision aids for people facing health treatment or screening decisions. Cochrane Database of Systematic Reviews. 2017;(1):CD001431.

Impact on Disparities
Likely to decrease disparities
Implementation Examples
The Agency for Healthcare Research and Quality’s (AHRQ’s) SHARE Approach promotes patient shared decision making (SDM) and trains health care providers to engage their patients in the decision making process (AHRQ-SHARE). The Mayo Clinic’s Shared Decision Making National Resource Center also supports implementation of SDM and includes decision aids for conditions such as osteoporosis, depression, rheumatoid arthritis, and diabetes (Mayo Clinic-SDM). Dartmouth-Hitchcock’s Center for Shared Decision Making was the first center in the US focused primarily on SDM; it includes Patient Support Corps volunteers to assist patients prior to and during appointments (Dartmouth-Hitchcock-SDM).
