Objectives:
To measure quality of care at general
practice consultations in diverse geographical areas, and to determine the principal correlates associated with enablement as an outcome measure.
Design:
Cross sectional multipractice questionnaire based study.
Setting:
Random sample of practices in four
participating regions: Lothian, Coventry, Oxfordshire, and west London.
Participants:
25 994 adults attending 53 practices
over two weeks in March and April 1998.
Main outcome measures:
Patient enablement, duration of
consultation, how well patients know their doctor, and the size of the
practice list.
Results:
A hierarchy of needs or reasons for
consultation was created. Similar overall enablement scores were
achieved for most casemix presentations (mean 3.1, 95% confidence
interval 3.1 to 3.1). Mean duration of consultation for all patients
was 8.0 minutes (8.0 to 8.1); however, duration of consultation
increased for patients with psychological problems or where
psychological and social problems coexisted (mean 9.1, 9.0 to 9.2). The
2195 patients who spoke languages other than English at home were
analysed separately as they had generally higher enablement scores
(mean 4.5, 4.3 to 4.7) than those patients who spoke English only
despite having shorter consultations (mean 7.1 (6.9 to 7.3) minutes. At individual consultations, enablement score was most closely correlated with duration of consultation and knowing the doctor well. Individual doctors had a wide range of mean enablement scores (1.1-5.3) and mean
durations of consultation (3.8-14.4 minutes). Doctors' ability to
enable was linked to the duration of their consultation and the
percentage of their patients who knew them well and was inversely related to the size of their practice. At practice level, mean enablement scores ranged from 2.3 to 4.4, and duration of consultation ranged from 4.9 to 12.2 minutes. Correlations between ranks at practice
level were not significant.
Conclusions:
It may be time to reward doctors who have longer consultations, provide greater continuity of care, and both
enable more patients and enable patients more.

Introduction |
|---|
|
|
|---|
The definition and measurement of quality of care in general practice is set to maintain a high profile as issues relating to quality assurance and clinical governance in primary care groups and local healthcare cooperatives1-3 engage management and professions.
Within general practice, work on quality and the development of performance indicators4-6 is in hand on issues of practice organisation, 7 8 care of continuing health problems,9-12 and achievement of public health targets. 13 14 However, the core activity of general practice remains the consultation. Two areas of work in this discipline are particularly relevant to this paper: the use of time in consultations and its relation to "enablement," an outcome measure that seems related to, but different from, satisfaction15-19; and continuity of care.20-22
Our two principal aims were to see if survey methods developed and used
to study quality of care at consultations in volunteer practices in
Scotland17 could be developed further and used on a large
scale with randomly selected practices elsewhere in the United Kingdom;
and to explore the correlates of enablement and to see whether these
could be modelled.

Research instruments
A preconsultation questionnaire was completed by all
patients aged 12 and over. One set of questions asked about problems in
general terms (acute or urgent, new or continuing, social,
psychological, administrative, wish for general health advice, need for
a prescription, returning on request), and a further set of questions
asked which of these problems they wished to discuss. The 12 question
version of the general health questionnaire and a set of five questions
on social wellbeing were added to develop the psychological and social
case-mix components.
that is, added to the
surgery session without having an appointment
or a temporary resident,
and whether a student was present.
After the consultation, the patient completed the patient enablement
instrument (figure). The original instrument has been developed from
previous work by the addition of a "not applicable" option.19 Its conceptual basis has been described
elsewhere17 and derives from the assumption that what is
important in predicting outcome is how the respondent feels and
perceives life.23 Responses of "much better,"
"better," and "same or less" or "not applicable" were
scored 2, 1, and 0 respectively, giving a score range of 0-12. Patients
also indicated whether a prescription was given and whether the
consultation was interrupted.

Populations sampled
The intention to recruit 50 doctors in 10 practices in each
of the four participating regions (Lothian, Coventry, Oxfordshire, and
west London) was achieved by inviting a random sample of
about twice the necessary size to attend a series of briefing meetings.
In practices of up to three partners all had to agree to take part, but
three out of four partners, four of five partners, or all but two
partners in larger practices were regarded as sufficient. Trainees and
assistants were included where appropriate. Practices were asked to
collect consultation data for two consecutive weeks during March and
April 1998. Ethical approval was obtained in all four regions.
Data handling
Information was analysed with SAS. We carried out multiple
regression analysis with enablement as the outcome variable, and
correlation coefficients were computed where appropriate to assess the
strength of associations between variables.

Overall, 221 doctors in 53 practices collected information on 25 994 consultations with adult patients. The mean enablement score for English speaking patients was 3.1 and the mean consultation length was 8.0 minutes. The 2195 patients who indicated they spoke languages other than English at home were categorised as "other language" patients. About a quarter of these expected to consult in their own language. Their consultations were more enabling (mean enablement score 4.5) and shorter (mean 7.1 minutes) irrespective of whether they received help to complete responses. Except where indicated, all analyses in this paper are based on the 23 799 consultations with English speaking patients. Mean duration of consultation for a further 7338 patients who did not complete a questionnaire was 0.37 minutes longer than for those who did.

Needs hierarchy and reason for consultation
Overall, 10 758 (45.2%) patients reported an acute
illness, 10 011 (42.1%) reported chronic health problems, 9855 (41.4%) reported social problems, and 7062 (29.7%) reported psychological problems (including general health questionnaire-12 scores of 5 or above). Administrative issues (including wishes for
general health advice and for prescriptions, without identification of
an acute or chronic problem) occurred in a further 2007 (8.4%) patients. Less than 1.0% of patients could not be categorised (237 patients), and 4760 (20.0%) of patients wanted to discuss more than
one problem.
Correlates
Consultations
Tables 1 and 2 show the principal correlates with
enablement at consultations. Table 1 shows that enablement was similar
across case mix. Mean duration of consultation increased when
consultations had a psychological component. High mean duration of
consultation was associated with a smaller number of short consultations and a greater number of long and very long
consultations.
|
Doctors
Mean enablement scores and mean durations of consultations
were calculated for individual doctors. Enablement scores at doctor
level (for English speaking patients) ranged from 1.1 to 5.3, and
durations of consultations ranged from 3.8 to 14.4 minutes. Both were
approximately normally distributed. The Spearman's rank correlation
between doctors' order for mean enablement and mean duration of
consultation was 0.38 for all 171 doctors with 50 valid enablement
scores, 0.66 for 52 doctors with over 120 valid enablement scores, and
0.93 for seven doctors with over 170 valid enablement scores.
We analysed data for both
English speaking and other language speaking patients, seen by English
speaking and other language speaking doctors, split by case mix for
duration of consultation, enablement, and the percentage of patients
who knew the doctor very well (data not shown). Other language speaking
patients knew their doctors better than did English speaking patients
(they generally attended smaller practices). They also reported
significantly higher enablement (mean scores 4.5 versus 3.1) and
shorter consultations (mean duration 7.1 versus 8.0 minutes) than did
English speaking patients. This was particularly noticeable for
biomedical presentations. Other language speaking doctors (all of whom
spoke Asian languages) seemed to enable other language speaking
patients with psychological problems less well than expected, probably
because their consultations in this area were significantly shorter.
Sex of patients and doctors
We matched patients and doctors
by sex (data not shown). Overall, 75.3% of patients seen by female doctors were female (5104 of 6779) compared with 59.1% seen by male
doctors (7931 of 13 415). Case mix was similar for male and female
doctors. Patients of male doctors knew them better. Enablement values
for male and female doctors were comparable overall, but female doctors
spent more time with their patients than did male doctors, particularly
when the patient did not know the doctor well.
High and low enabling doctors
Doctors were divided into
fourths on the basis of their enablement scores. Table 3 shows that doctors in the highest as against the lowest fourth had longer consultations, had more patients who knew them very well, worked with
smaller lists, and enabled more in every analysis carried out.

Practices
List size and knowing the doctor well
Table 4
shows that the proportion of patients who knew the doctor well (a
possible proxy for continuity) decreased as total list increased. The
three largest practices seemed to go against that trend and were
examined separately. In two of these practices the proportion of
patients knowing the doctor well decreased as list size increased. The
third practice operated an individual list system and had the same
continuity as the best groups in the table. Their mean durations of
consultations were, however, short
particularly for patients who did
not know them well
and their mean enablement was low. Mean duration of
consultation and mean enablement scores for patients who both did and
did not know the doctor well show the persistent benefit of this
attribute in terms of enablement (table 4). Consultations where the
patient knew the doctor well were generally slightly longer than those
where this was not the case.
Multiple regression
A multiple regression analysis was carried out at
consultation level, with enablement as the outcome variable. Several
covariates were identified as significant predictors of enablement,
including knowing the doctor very well and duration of consultation.
The overall predictive power of the model was, however, low (adjusted
r2=0.037).

Feasibility and methods
The first purpose of our study was to develop previously used survey methods and to test their utility and
acceptability in diverse geographical areas. We achieved a 38% take-up
rate from our random sample of practices, this being higher for larger practices. The practices that declined had a similar demographic profile to those that accepted, but we cannot comment on whether the
patterns of care they offered would also have been similar. We achieved
a cross section of small, large, deprived, and non-deprived practices
across the four participating areas, and these practices also differed
in the ethnic mix of both patients and doctors.
Enablement
As with any outcome measure it is hard to know whether
reported enablement reflects true enablement. The desire to please a
familiar doctor and differences between cultural groups could create
artificial differences. We found, however, that some doctors
consistently enabled better than others, irrespective of all the
aspects of case mix we studied. The finding of differences between
English speaking and other language speaking patients was of particular
interest and requires to be researched further with both quantitative
and qualitative methods.
Correlates with enablement
The second purpose of our study was to measure enablement
and to identify its principal correlates. Doctors seemed to
discriminate well about the needs of their patients, achieving similar
overall enablement scores for most case mix presentations. Predictable
differences in outcome and duration of consultation were related to age
and sex of patients, to being added to surgery sessions without having
appointments, and to having a consultation that was interrupted. The
negative effect of not receiving a prescription when one was wanted was
confirmed. The effect of ethnicity
reflected by languages spoken at
home
in producing high enablement and short duration of consultation
confirms the difficulty of judging quality in a multicultural society.
The absence of an overall effect of social and psychological problems
(a possible proxy for deprivation) on enablement or duration of
consultation may be surprising, but it seems to be explained by the
tendency for patients with social problems alone to receive shorter and
less enabling consultations being compensated for by the fact that
those with added psychological problems received longer and more
enabling consultations. The substantial benefit of knowing the doctor
very well gives an important contemporary message as does the fact that
this benefit is progressively less likely to be found as practice size
increases. The difficulty of modelling these variables into a single
explanation for enablement
reflecting the large degree of variation
within the enablement scores of individual doctors
confirms the
complex nature of consultation in general practice. The ability of
doctors to allocate time efficiently compounds the problem. Some
doctors are, however, clearly less effective than others.
Further work
Work is currently in hand to develop a consultation quality
measure at doctor and practice level and to compare results with other
practice level performance indicators, which are based on routinely
available NHS data.
