Objective:
To measure patients' perceptions of
patient centredness and the relation of these perceptions to outcomes.
Design:
Observational study using questionnaires.
Setting:
Three general practices.
Participants:
865 consecutive patients attending the practices.
Main outcome measures:
Patients' enablement,
satisfaction, and burden of symptoms.
Results:
Factor analysis identified five components. These were communication and partnership (a sympathetic doctor interested in patients' worries and expectations and who discusses and
agrees the problem and treatment, Cronbach's
=0.96); personal relationship (a doctor who knows the patient and their emotional needs,
=0.89); health promotion (
=0.87); positive approach (being definite about the problem and when it would settle,
=0.84); and
interest in effect on patient's life (
=0.89). Satisfaction was
related to communication and partnership (adjusted
=19.1; 95%
confidence interval 17.7 to 20.7) and a positive approach (4.28; 2.96 to 5.60). Enablement was greater with interest in the effect on life
(0.55; 0.25 to 0.86), health promotion (0.57; 0.30 to 0.85), and a
positive approach (0.82; 0.52 to 1.11). A positive approach was also
associated with reduced symptom burden at one month (
=
0.25;
0.41 to
0.10). Referrals were fewer if patients felt they had a
personal relationship with their doctor (odds ratio 0.70; 0.54 to
0.90).
Conclusions:
Components of patients' perceptions can
be measured reliably and predict different outcomes. If doctors don't provide a positive, patient centred approach patients will be less
satisfied, less enabled, and may have greater symptom burden and higher
rates of referral.

Introduction |
|---|
|
|
|---|
Although the patient centred model of doctor consultation
is widely advocated, its use in practice is probably rather
limited.1-3 The model encompasses five principal
domains
exploring the illness experience or expectations, the whole
person, finding common ground, health promotion, and enhancing the
doctor-patient relationship.4 An important perceived
limitation on implementation is pressure on consultation time. Thus,
evidence that specific components of the model affect outcome is
important to increase its use.
A systematic review of 21 studies found that better communication improved outcomes, although most studies didn't specifically assess the patient centred model and a minority were from general practice.5 Furthermore, other approaches such as empowerment and a positive approach may be equally powerful.5-6 The few studies in general practice that specifically assessed patient centredness suggest it is related to satisfaction and use of resources.7-9 They also found it may be as important to measure patients' perceptions than what doctors say in a consultation. However, the most important components of the patient centred model are unclear, and their relation to outcomes requires confirmation.
Conventionally, patient centredness is measured by doctors' verbal
behaviour.4 It therefore does not capture patient
perceptions, non-verbal behaviour, or the ongoing patient-doctor
relationship. Existing patient questionnaires
4 7
do not
document diverse domains of perceptions and may incorporate difficult
concepts for some patients (such as questions about the doctor
discussing respective roles). Domains that could affect patients'
preferences include communication, partnership, health promotion, and
understanding the whole person,10 but it is unclear
whether these are relevant to patients' perceptions of doctors'
behaviour or how such perceptions relate to outcome. We conducted this
study to document measures of patients' perceptions of patient
centredness and how these measures relate to outcomes.

Participants and methods |
|---|
|
|
|---|
The study was approved by the Salisbury and South East Hampshire local research ethics committees. We approached three local practices that were active in research and had the infrastructure to provide reception and clerical help. The practices served 24 100 patients, with an average patient turnover of 8.3% a year. One practice was in a deprived area of a large provincial city the second was a training practice in a cathedral city, and the third was a training practice in a market town with patients from urban and rural areas.10 We invited consecutive patients attending the surgery to participate. All patients able to complete the questionnaire were eligible.
Questionnaire
Participants completed a short questionnaire before their
consultation in which they were asked to agree or disagree on a seven
point Likert scale (very strongly agree to very strongly disagree) with
statements about what they wanted the doctor to do. A questionnaire
after the consultation asked patients about their perception of the
doctor's approach. Both questionnaires were based on the five main
domains of the patient centred model: exploring the disease and illness
experience, understanding the whole person, finding common ground,
health promotion, and enhancing the doctor-patient
relationship.

Sample size
To detect a correlation of 0.15 (half the previous effect
size9) between patients' rating of doctor behaviour and
outcome with a power of 80% and 95% confidence we needed 526 patients, allowing for a third loss to follow up. If patient
centredness was assumed to explain 5% of the variance of satisfaction,
we needed 482 patients to detect an R2 of
0.05 with up to 10 variables.
Analysis of data
We scanned data using Formic 3 software and analysed
them with SPSS for Windows and Stata for Windows software. We used the
factor analysis technique to establish whether there were distinct
components within the data on patient centredness. Varimax rotation
ensured that the factors identified were as distinct as possible. We
built scale scores from the factors by adding the component
questionnaire items together (unweighted) and dividing by the number of
items and assessed the internal reliability using Cronbach's
statistic.

In all, 865 consecutive patients attending the
surgery agreed to participate and 661 (76%) returned the
questionnaires. Respondents were similar to non-respondents in feeling
unwell (44% (279/635) v 38% (66/165)) or worried (55%
(352/640) v 58% (98/168)) and strongly wanting good
communication (43% (264/610) v 45% (69/154)), partnership
(27% (166/617) v 32% (50/157)), and health promotion (25%
(159/637) v 25% (42/166)). Compared with data from the
national morbidity survey on patients attending general practice, a
similar proportion of respondents were adults aged 17 to 64 (10% aged 0-16, 73% aged 17-64, and 18% aged
65 in sample v 20%,
62%, and 18% respectively in morbidity survey), married or living as
married (67% v 60%), working (57% v 57% of
patients over 16), and female (66% v 60%).
Identifying components of patient centredness
Table 1 shows patients' ratings of their doctor's
approach. Factor analysis suggested a four to five component solution.
Four components explained 93% of the variance and the fifth 3% of the variance.
Predictors of satisfaction, enablement, and resolution of
symptoms
The model predicting satisfaction with the consultation
explained most of the variance (R2=0.78,
table 2). The main independent predictors of satisfaction were
patients' perceptions of communication and partnership and a positive
doctor approach. A simple global rating of satisfaction (on a seven
point Likert scale) also showed that communication and partnership is
the strongest predictor of satisfaction (
=0.96; 95% confidence
interval 0.87 to 1.05; P<0.001). Independent predictors of enablement
were patients' perceptions of the doctor's interest in the effect of
the problem on life and health promotion and a positive
approach.

Predictors of use of health services
No domain of patient centredness was associated with
reattendance and investigations. In multivariate analysis, referrals
were fewer if patients felt they had a personal relationship with their
doctor after worry about the problem, age, and reason for consultation
were controlled for (odds ratio 0.70; 95% confidence interval 0.54 to
0.90).
Relating what happened to patients' previous expectations
By subtracting patients' rating of doctor behaviour from
corresponding previous preferences, we could also assess the mismatch
between patients' expectation and what they felt happened in the
consultation. A mismatch therefore represents expectations not met.
Satisfaction was reduced if expectations were not met for communication
and partnership (adjusted 
13.8;
11.4 to
16.2), a positive
approach (
2.0;
0.3 to
3.7), and an examination (
5.3;
0.9
to
9.7) but were not affected by expectations of a prescription.
Enablement was also less if expectations were not met for an
examination, health promotion (
0.38;
0.14 to
0.63), and a
positive approach (
0.64;
0.38 to
0.90). If expectations of a
personal relationship were not met, referrals were more likely (odds
ratio 1.41; 1.04 to 1.91). After potential confounders were controlled
for (age, symptom burden at baseline, type of problem, worry about the
problem, anxiety, sickness and disability benefit), symptom burden at
one month was worse if expectations of a positive approach were not met
(adjusted
0.21; 0.07 to 0.36).

Discussion |
|---|
|
|
|---|
We found that patients want a patient centred and positive approach, and if they do not get it they are less satisfied, less enabled, and may suffer greater symptom burden. The measures we used identified five factors describing patients' perceptions of patient centredness and strongly support use of this model in general practice.4
Limitations of the study
The sample and response bias have been previously discussed
and are not likely to alter the inferences of this
study.10 Nevertheless, cause and effect in observational
studies must be interpreted carefully. We found, for example, that a
personal and understanding relationship was associated with greater
symptom burden, even though we crudely controlled for type of problem. The most likely explanation for this finding is that symptoms are more
likely to be prolonged for conditions in which a personal and
understanding approach is relevant (such as anxiety, depression, or
chronic disease). When we took account of patients' expectations before the consultation, a personal relationship was no longer significantly associated with symptom burden. The relation between patient centredness and outcome needs to be investigated in randomised trials or cohort studies using a tightly defined and homogeneous case
mix to explore the cause and effect further.
Important aspects of doctor's approach and relationship
Comparison of patients' ratings of their doctor's behaviour with preferences expressed before the consultation shows two
differences. Firstly, before the consultation, patients had a strong
preference for a partnership approach,10 but afterwards partnership was more closely related to communication. Secondly, a
positive approach was part of a preference for communication before the
consultation, but patients' perceptions of a positive approach were
distinct from their perceptions about communication in this study.
Importance of positive approach
A previous study found that being positive and
definite about the diagnosis and prognosis was positively related to
resolution of symptoms.6 We found that it had a positive
effect on satisfaction, enablement, and burden of symptoms. It may be
difficult to be positive if the doctor is genuinely uncertain about the
diagnosis, which is often the case in primary care when patients
present with early disease. Nevertheless, doctors should be aware that
airing their uncertainties about diagnosis and prognosis might reduce
satisfaction and empowerment.
Conclusion
The components of patients' perceptions of patient
centredness and a positive approach can be measured reliably. Each is
associated with different outcomes of a consultation. Measurement of
patients' perceptions of patient centredness provides a marker of the
quality of care. If doctors don't provide a positive, patient centred
approach patients will be less satisfied, less enabled, and may have
greater symptom burden and use more health service resources.
