approach to care delivery such that pro-
fessionals work within their full scope
of practice and without intentional
duplication of services. According to
the Interprofessional Shared Decision
Making model (Figure 1), the process of
shared decision making involves: 1)mak-
ing explicit the decision to be made; 2)
exchanging information on options,
benets, and harms; 3) discussing val-
ues for outcomes of options and patients
preferences; 4) determining feasibility
of the options; 5) expressing a preferred
choice; 6) choosing an option; and
7)implementing the chosen option. This
model was built by an interprofessional
and international team upon ndings
from a theory analysis of previous con-
ceptual models (Légaré, Stacey, Pouliot
et al., 2011; Stacey, Légaré, Pouliot,
Kryworuchko & Dunn, 2010).
The interprofessional shared deci-
sion making model is composed of two
main axes, with the vertical axis repre-
senting the shared decision making
process and the horizontal axis repre-
senting the individuals involved in
the process (Légaré, Stacey, Gagnon
et al., 2011; Légaré, Stacey, Pouliot et
al., 2011). There are two main ‘teams’:
the patient/family team and the inter-
professional team that may include one
member assuming the decision coach-
ing role. Ultimately, the two teams
combine to form one. There are four
assumptions underlying the model.
First, involving patients in shared deci-
sion making is essential for reaching
decisions that are informed and based
on individual patient values. Second,
by the interprofessional team having
a common understanding of the ele-
ments of the shared decision making
process and recognizing the inuence
of various individuals on the process,
there will be improved success in reach-
ing a shared decision. Third, achieving
an interprofessional approach to shared
decision making may occur synchron-
ously in the example of a family confer-
ence in the intensive care unit but, more
often, occurs asynchronously. Fourth,
family or signicant others are import-
ant stakeholders involved or implicated
by the decision and their values and
preferences may not be consistent with
the patient.
Tips for nurses. Oncology nurses are
key members of the interprofessional
team and often inuential in the shared
decision making process when patients
are facing preventative, screening or
treatment decisions. Reecting upon
your role in shared decision making
may help you be more aware of how
you can better support patients fac-
ing these tough cancer decisions. Are
patients aware that there is more than
one option (e.g., including status quo)?
Are your preferences or those of other
team members inuencing the patients
or are you considering the patients’ val-
ues and preferences? Who on the health
care team is responsible for coaching
the patient into the decision making
process and, thus, assuring the patient
understands his/her options? What is
the typical process by which decisions
are made? Are patients experiencing
decisional conict? (see Table 2).

Decision AiDs
Patient decision aids and decision
coaching are tools that can facilitate
the process of shared decision making.
Patient decision aids are dened as, at
a minimum, making explicit the deci-
sion, providing evidence-based infor-
mation on options, benets and harms,
and helping patients clarify their values
for outcomes of options to reach a pre-
ferred option (Stacey et al., 2014). They
may also include probabilities indicat-
ing the chances of benets and harms,
personal stories, and guidance in the
steps of decision making. Formats for
patient decision aids typically include
printed materials, videos, and/or com-
puter-based interactive programs. They
are designed to be used either in prepa-
ration for practitioner consultation or
for use with a practitioner during the
consultation. While the main goal of
educational materials is to improve
knowledge, patient decision aids sup-
port progress in decision making.
Findings from a systematic review
evaluating the eectiveness of deci-
sion aids for people facing treatment
or screening decisions revealed 52 of
115 (45%) randomized controlled trials
were focused on oncology decisions
(Stacey et al., 2014). Topics include:
a)screening for prostate, colon, cervix,
and breast cancers; b) genetic testing
for breast, ovarian, and colon cancer;
c) surgical treatment including breast
cancer (e.g., lumpectomy versus mas-
tectomy), prostate cancer (e.g., prosta-
tectomy versus radiation therapy ver-
sus active surveillance), prophylactic
mastectomy, orchiectomy for advanced
prostate cancer; and d) chemotherapy
or chemoprevention. Rigorous evalu-
ation of patient decision aids indicates
that patients who use decision aids have
improved quality of decisions, as evi-
denced by enhanced knowledge, a more
accurate understanding of the chances
of benets and harms, and improved
match between patients’ values and
the chosen option (Stacey et al., 2014).
They reduce overuse of options that
are not benecial for the majority of
those using it and they have a tendency
