Objectives:
To explore the views of general practice
registrars about involving patients in decisions and to assess the
feasibility of using the shared decision making model by means of
simulated general practice consultations.
Design:
Qualitative study based on focus group interviews.
Setting:
General practice vocational training schemes in south Wales.
Participants:
39 general practice registrars and eight
course organisers (acting as observers) attended four sessions; three simulated patients attended each time.
Method:
After an introduction to the principles and suggested stages of shared decision making the registrars conducted and
observed a series of consultations about choices of treatment with
simulated patients using verbal, numerical, and graphical data formats.
Reactions were elicited by using focus group interviews after each
consultation and content analysis undertaken.
Results:
Registrars in general practice report not being trained in the skills required to involve patients in clinical decisions. They had a wide range of opinions about "involving patients in decisions," ranging from protective paternalism
("doctor knows best"), through enlightened self interest
(lightening the load), to the potential rewards of a more egalitarian
relationship with patients. The work points to three contextual
precursors for the process: the availability of reliable information,
appropriate timing of the decision making process, and the readiness of
patients to accept an active role in their own management.
Conclusions:
Sharing decisions entails sharing the
uncertainties about the outcomes of medical processes and involves
exposing the fact that data are often unavailable or not known; this
can cause anxiety to both patient and clinician. Movement towards further patient involvement will depend on both the skills and the
attitudes of professionals, and this work shows the steps that need to
be taken if further progress is to be made in this direction.

Introduction |
|---|
|
|
|---|
Involving patients in decision making is becoming an
important clinical task,
1 2
particularly in general
practice, where health professionals can guide patients before they
enter domains in which treatment bias may operate. Sharing information
is not the same as sharing decisions,3 and there is no
evidence that the available models for involving patients in decision
making are feasible or that doctors have the required
skills.4 In broad terms, three models of doctor-patient
interaction
paternalism, informed choice, and shared decision
making
have been described and their inherent assumptions
debated.5 A paternalistic approach involves taking the
responsibility for decision making. Informed choice is at the opposite
end of the spectrum, where the patient is provided with
"sufficient" information and the clinician withdraws from the
decision process. Shared decision making describes the middle
ground.6 But exactly how the principle of "involving" patients resonates with practice has not been
explored.

Towle's suggested steps for shared decision
making9

It is therefore important to know if the theoretical
constructs need to be adapted for use in clinical settings. We used
focus groups to elicit the reactions of general practice registrars when they were asked to use a suggested model9 in
interactions with simulated patients in three specific disease areas
(benign prostatic hypertrophy, menopausal symptoms, and atrial
fibrillation). In contrast with one to one interviews, focus groups can
explore differences in opinions as well as defining consensus and
capitalise on group interaction to uncover hidden
attitudes.

Study sample
During 1998 four group interviews were held within the half
day release sessions of vocational training schemes for general
practice registrars in south Wales. Most researchers aim for
homogeneity to gain peer group safety and the sample was purposefully
selected to enable us to gauge the reactions of new general
practitioners to the concept of involving patients in decision making.
All the registrars attending three vocational training schemes in south
Wales were invited to take part in the study.
Interview structure
Participants were introduced to the concept of sharing
decisions with patients and provided with an outline of suggested
stages9 and a description of the clinical problems they
would encounter. Three small sets (three or four people in each) were
formed. Individuals volunteered in turn to consult with a simulated
patient who had one of the three roles described in the box. The
doctors were asked to conduct the discourse as if it were a
"normal" consultation. The patients' roles and presentations were
chosen, firstly, because they are typical of those seen in practice;
secondly, because each clinical problem has treatment options that
legitimately allow clinical equipoise
the patient's views can
determine choice of treatment; and, thirdly, because systematic review
data are available regarding the options. The simulated patients were
non-medically trained individuals with previous experience in
undergraduate training in communication skills.

Simulated patient roles
The vignettes described clinical scenarios in which the problem has been identified so that the participants could concentrate entirely on the decision making aspect of the consultation: Menopausal symptoms Patient undecided about hormone replacement therapy and anxious about the risk of breast cancer Benign prostatic hypertrophy Patient wants to know more about the typical options that face a man who is told that he has "prostatism," with no other risk factors Atrial fibrillation Patient wants to know about the pros and cons of warfarin and aspirin for prevention of stroke |
Focus group interviews
Group interviews were held after each consultation and
reactions explored use of an interview schedule (see box). The
simulated patients were present and given opportunities to contribute.
The total duration of the interview was 80-90 minutes, and the
proceedings were audiotaped and transcribed.

Analysis
The transcripts were examined by three authors (GE, AE,
RGw) to identify emergent themes.11 These were agreed by
discussion and the data categorised independently by two authors (GE
and AE), who subsequently agreed an overall classification. As our
intention was to present viewpoints rather than achieve statistical
generalisability, the data are not presented numerically. Trends and
majority agreements, however, are indicated. The results were checked
with the simulated patients and three of the course organisers and
modified where required.

Of 45 registrars within the training schemes during the study period, 39 (87%) attended one of four interviews in different parts of south Wales. Eight course organisers acted as observers, taking the total number of clinicians involved to 47. Five themes were identified.
Views about "shared decision making"
Positive and negative views about involving patients
"it was new...doing something
different from the talk we normally do"
and a spectrum of opinions
was elicited. At one end was the view that no matter how data are
presented it is unrealistic to expect patients to participate in
decision making
"the patient has no information to make an informed
choice. At the end of the day it is a professional judgment"; "they
[the patients] haven't been to medical school for 5 years, how can we expect them to make a decision?"
There was also evidence of a professional reticence to undertake this
approach
"I wouldn't have dreamed of showing you [the patient]
the figures." Others were more receptive to the idea and the
potential benefits of involving patients. This was thought to be
particularly true when options were equally tenable
"it is more
rewarding using them [the risk tools] because you feel you have
informed the patient. They've got the information and have some part
in the decision rather than just listen to us talking to them";
"[sharing decisions] unburdens the
doctor...[when] there's a lot of uncertainty about
what is the best thing to do."
Barriers to sharing decisions
Lack of information and a reluctance to share data
Most participants acknowledged the potential benefits, and discussions revolved around the difficulty of actually involving patients. It was said that sharing decisions "...is
entirely content specific. You can't lay out options and their pros
and cons if you don't know them"; "...threw into
stark reality how often patients ask questions for which we don't have
the information in the depth they require at our fingertips." Some
thought that "specialists" might be better placed than generalists
to take on this task. Nevertheless, there was agreement that patients
want information in depth. All the participants agreed that data had to
be robust
"it has got to be cast iron data."
Participants thought that it was very
important to achieve the correct "timing" for shared decisions. In
their opinion only a few consultations contain problems for which it is
feasible to provide options. Decision making in their view should not
be imposed on patients who are anxious and not ready to consider
choices. Lack of time was cited as a barrier, particularly the time it
would take to find accurate data, though this was not overemphasised.
The view emerged that it is unusual for decisions to be taken within
one consultation, so the task could be staged. Further discussions are
often necessary and the agreed view was that
"...sharing a decision is a process not an event."
Contextual modifiers
Many participants emphasised the need
to be sensitive to "contextual" modifiers such as age and
educational achievement. It was widely thought that some patients would
have difficulty in understanding outcome data presented as
probabilities. Presentations of choices, they said, often have to be
simplified and at times omitted altogether. Participants were also
conscious that established consulting patterns within a longstanding
professional relationship could militate against the introduction of a
new approach to decision making.
Types of decisions
Another obstacle was the nature of the
decision itself. Sharing decisions was considered particularly
appropriate in situations of professional equipoise about the
"best" choice of treatment. It was thought that situations that
lacked equipoise (such as urgent or dangerous medical problems) or
situations of conflict (where patient "demand" is contrary to
empirical evidence) needed different decision making approaches.
Reported current practice
When they were asked to compare these techniques against
their "usual" practice most registrars stated that they normally
bias their presentation of facts and consciously "steer" patients
"you choose the data to help the patient make the decision you think they ought to make. I'm sure I do that."
"I try to
establish what the patient really wants...then I push
the information in that direction."
Some of the participants, however, were not prepared to allow patients
into the decision making arena
"if the doctor feels that one course
of treatment is better than another course of treatment, then that
should be strongly pressed home."
There was also an unchallenged expression of irritation with the notion
of the "informed patient," and data were viewed as a method of
enforcing the doctor's decision
"they've come in after reading the
damn patient leaflet and are worried about side effects. There's no
way they can assess in their head what the risks are, so they just
don't take it [the medication]"; "I spend a lot of my time
telling people that they don't need whatever they've barged in and
demanded...so statistics could be quite useful for that."
Training and skill implications
Although all the registrars had previously received
training in communication skills, they all agreed that their previous
experience of "...teaching had concentrated on the
first part of the consultation. The emphasis has been on achieving rapport, matching agendas, and problem solving." Most participants were positive about the techniques being explored, which contrasted with their ambivalence about involving patients in decision making.
Insights into the process of sharing decisions
Explicit about process
The registrars thought that an essential feature of
successful patient involvement was explicitness about the decision process and indicated that a useful way of legitimising patient involvement was by the use of phrases such as "this is a problem on
which doctors do not have one view." Many registrars recounted that
when the phrase "what would you like?" is used as a ploy to explore
patient views, the typical response is, "I don't know, you're the
doctor." There was general agreement about the need to
develop methods of involving patients that seem neither insincere nor
"rhetorical."
Portrayal of options
The participants noted that an important part of the
process was a clear portrayal of choices. Some noted that they
described options merely to undermine or dismiss them. Others noticed
that they did not list all the options available
that there was a
tendency not to describe the choice of "no action" or of deferring
a decision.
Patient role in decision making
The doctors admitted that it was not their usual
practice to ask patients about their preferred role in decision making.
There was, however, an underlying assumption that most patients do want
to be involved and that clinicians are good judges of their
preferences
"I think there is this kind of intuitive judgment
[about preferred role] that I often make when I first talk to a
patient in the first part of the consultation."
Opinions about possible "outcomes" of sharing decisions
For many participants a positive outcome of sharing
decisions was the increased sense of confidence that resulted from the
feeling of being "protected by data." More commonplace in the
discussion was the expression of concern about the potential anxiety in
patients that could result from too much information and the added
responsibility of decision making in the face of complex data about
probabilities
"it's clear on an intuitive level that `doctor
uncertainty' is likely to distress a lot of patients"; "telling
people about small risks will probably cause more trouble than keeping
quiet until problems crop up."

Discussion |

|
|
|---|
Our exploratory work shows that this group of junior doctors had not developed the skills needed to involve patients in clinical decision making. These practitioners were in transition between the "hospital based" clinical environment and the culture of general practice; experienced doctors might react differently. The registrars were unaware of the benefits of patient participation in decision making and thought they did not have the information necessary to explain the risks and benefits of treatment choices. They admitted that "friendly persuasion"15 was their usual practice, justified on the grounds that the responsibility of being involved in decisions would lead to increased (and by implication unacceptable) anxiety in patients.
The use of simulated patients can be criticised for being one remove away from "actual" practice.16 Nevertheless, because our aim was to obtain views that were not based on abstract notions, this method was acceptable to the registrars and provided them with as close an experience as possible of the concepts of shared decision making within a peer group environment.
The stages of shared decision making suggested by Towle9 need modification to take into account the context, the type of decision, and the amount of control the patient prefers within the different stages of the interaction.10 Population based surveys cannot predict role preference17 and involvement needs to be tailored appropriately at every interaction.18 This work illustrates the complexity of achieving partnership with patients and the illogicality of asking patients about their preferred role until they have realised the possible harms and benefits entailed and their associated probabilities. Then, and only then, can it be legitimate to ask whether individuals want to take an active role in decision making.10
Our results show that practitioners need to adapt to
varying contexts, preferences of patients, and types of
decisions.19 To argue that patients should always be
involved in clinical decisions is unwise. But as information becomes
readily available to all, this work starts to identify some of the
steps required to implement the process effectively.
