Objective:
To assess the acceptability and safety of a
minor illness service led by practice nurses in general practice.
The role of nurses in primary care has changed recently and
is set to evolve further with the development of services such as NHS
Direct, the telephone helpline staffed by nurses to advise callers on
the most appropriate health care.1 Nurses' roles have
expanded into those of nurse specialists (who are usually trained to
carry out specific roles in the assessment and management of patients
with specific conditions such as diabetes or asthma), nurse
practitioners (who are usually trained to manage more diverse conditions), and those who are managing the care of patients with chronic diseases. Recently, there has been discussion of nurses managing patients with undifferentiated minor medical problems. Not
only is this likely to be important in the NHS in the future but it
might also be welcomed by nurses keen to develop new skills and general
practitioners concerned about their own increasing workload.
Our aim was to assess in a multicentre, randomised controlled trial the
acceptability and effectiveness of a practice based minor illness
service led by nurses and to compare it with the routine care offered
by general practitioners. We specifically looked at practice nurses
rather than nurse practitioners because comparatively little research
has been done on the role of practice nurses. A search of Medline,
CINAHL, Embase, and the Social Science Citation Index found just two
British studies evaluating the management by practice nurses of minor
illnesses in primary care.

Although the results of
these studies generally supported nurse management, the studies were
confined to single practices, focused on process measures, used
informal indicators of patient satisfaction, and were not randomised
controlled trials.
Nurses and general practitioners
Design:
Multicentre, randomised controlled trial.
Setting:
5 general practices in south east London and Kent representing semi-rural, suburban, and urban settings.
Participants:
1815 patients requesting and offered
same day appointments by receptionists.
Intervention:
Patients were assigned to treatment by
either a specially trained nurse or a general practitioner. Patients seen by a nurse were referred to a general practitioner when appropriate.
Main outcome measures:
The general satisfaction of the
patients as measured by the consultation satisfaction questionnaire.
Other outcome measures included the length of the consultation, number of prescriptions written, rates of referral to general practitioners, patient's reported health status, patient's anticipated behaviour in
seeking health care in future, and number of patients who returned to
the surgery, visits to accident and emergency, and out of hours calls
to doctors.
Results:
Patients were very satisfied with both nurses and doctors, but they were significantly more satisfied with their consultations with nurses (mean (SD) score of satisfaction 78.6 (16.0)
of 100 points for nurses v 76.4 (17.8) for doctors; 95% confidence interval for difference between means
4.07 to
0.38). Consultations with nurses took about 10 minutes compared with about 8 minutes for consultations with doctors. Nurses and doctors wrote
prescriptions for a similar proportion of patients (nurses 481/736
(65.4%) v doctors 518/816 (63.5%)). 577/790 (73%)
patients seen by nurses were managed without any input from doctors.
Conclusion:
Practice nurses seem to offer an effective service for patients with minor illnesses who request same day appointments.

Five general practices in London and Kent participated in
the study. The two practices in south east London serve a mostly urban
area with a culturally diverse population that is often transient,
which results in a high turnover of patients. The practices in Kent
serve some densely populated and some semi-rural areas; many people
commute from the area to London. One nurse from each practice took
part, and 19 general practitioners acted as controls. The average age
of the nurses was 36.2 (SD 5.6) years, with an average of 8.4 (3.8)
years of experience in practice nursing. Three nurses had no experience
of seeing patients with minor illnesses; one had a little experience,
seeing these patients irregularly; and one ran open surgeries in which
patients with routine, non-urgent problems (such as blood pressure
checks or vaccinations) as well as those with minor illnesses were
seen. None of the nurses had had specific training in treating patients
with minor illnesses.
Recruitment and exclusion criteria
There was a two month pilot period after the nurses were
trained; this was followed by 18 consecutive weeks of recruitment of
patients between November 1998 and March 1999.
|
Intervention
Nurses managed the patient's care and took the history,
performed a physical examination, offered advice and treatment, issued
prescriptions (which required a doctor's signature), and referred the
patient to the doctor when appropriate. The amount of time that nurses
could spend on each consultation was not defined, but appointments were
booked at 10 minute intervals. Nurses did not offer routine follow up
unless they identified a nursing problem that needed review (for
example, dressing a wound).
Outcome measures
The key outcome variable was the patient's general
satisfaction as measured by the consultation satisfaction questionnaire.
4 5
Patients completed the questionnaire
after the consultation and before leaving the surgery. Subscales on this questionnaire measure professional care, depth of relationship, and perceived time and were used as secondary outcomes. Responses to the questionnaire are indexed to a scale of 0-100; most scores will
fall in the range of 60-80. Information collected from the doctor or
nurse included the presenting complaint, the number of prescriptions
written, the proportion of consultations for which advice was recorded
by the doctor or nurse, the number of patients referred to the doctor
(for nurses), and the length of the consultation (excluding the time it
took nurses to find a doctor to advise them or to sign a prescription).
Another questionnaire was sent to the patient two weeks after the
consultation and if necessary two reminders were sent one week apart.
This questionnaire measured the patient's reported health status, the
patient's reported compliance with drug treatment, the rating of the
quality of explanation and advice given, whether the patient had
returned to the surgery, and the patient's anticipated behaviour in
seeking health care for the same condition. Self reported health status
was measured using the scale developed by Murphy et al.6
Data on critical events, attendance at accident and emergency
departments, and out of hours calls were collected from the medical
records of those who did not respond to the postal questionnaire.
Data analysis
It was calculated that 1060 valid responses would be
sufficient to detect an effect size of 0.2 SD (4 points on the
satisfaction scale of 0-100) at the 95% confidence level with a power
of 90% using two tailed tests.
2 for categorical
variables, the Student's t test for continuous variables
that met the requirements for parametric tests, and the Mann-Whitney U
test for variables that did not.

Study participants
A total of 1815 of 2021 eligible patients (90%) entered
the trial (fig 2). Altogether, 1713 of 1815 patients (94%) who
were randomly allocated received the allocated intervention. For 78 patients (4%) it was not possible to confirm which intervention had
been received because the consultation form was not completed. The
response rates to both the consultation satisfaction questionnaire and
the postal questionnaire were over 75% (fig 2). Fifteen patients were
withdrawn from the study after being randomly allocated because it
became apparent that they were ineligible.
|
those seen by the nurses and those seen by
the doctors
were comparable in terms of age, sex, the number who
usually preferred to see a female doctor rather than a male, and their
reported rates of consultation in the previous 12 months (table 1). The
range of presenting conditions was broad, with no significant
differences between the two groups (table 1).
|
Variables measured for each visit
On average the nurses spent about two minutes longer on
each consultation (mean 10.2 minutes for nurses v 8.3 minutes for doctors; 95% confidence interval of difference between means
2.43 to
1.28; P<0.001) (table 2). There was significant variation between individual nurses in the mean length of consultations (mean length 7.9, 8.9, 10.8, 11.7, and 12.8 minutes; P<0.001), showing
that some nurses seemed to be as fast as doctors. Of the 790 patients
seen by nurses for whom data were available 577 (73%) were managed
without immediate referral to a doctor (except for having prescriptions
signed); 153 of 790 (19%) had to be seen by a doctor. For the
remaining 60 (8%) the nurses needed only to have a discussion with a doctor.

Patients' satisfaction and future behaviour
Generally patients expressed greater satisfaction with the nurses; this was statistically significant in the subscales of
the questionnaire that measured general satisfaction,
professional care, and perceived time (table 3). Linear regression
showed that longer consultations were significantly related to the same three satisfaction subscales (general satisfaction SE=0.028, P=0.046; professional care SE=0.028, P=0.049; perceived time SE=0.028, P<0.001). However, multiple linear regression analysis showed that a
significant relation between the patient's allocation and scores of
satisfaction remained after adjusting for time spent in the
consultation, although it was slightly weakened (general satisfaction
SE=0.029, P=0.047; professional care SE=0.028, P=0.004; perceived time
SE=0.028, P<0.001). Being referred to the doctor seemed to have an
adverse effect on satisfaction. The mean score of general satisfaction
for patients who were seen by a nurse and who then had to see a doctor
was 71.7 out of 100 compared with 80.0 for those who did not have
to see the doctor as well (P=0.014, 95% confidence interval for
difference between means
11.6 to
4.9). Satisfaction was not
related to the sex of the doctor. Both groups of patients reported that
they were very satisfied with the quality of advice and the
explanations that they had been given about their
condition.

2=48.268, P<0.001).
When asked what they were likely to do in future for episodes of the
same illness, more than 91% (566/616) of those who had seen a doctor
and 94% (590/629) of those who had seen a nurse said that they would
again present to a health professional (
2=1.446,
P=0.229). Of these, 94% (530/566) of those who had seen a doctor and
96% (567/590) of those who had seen a nurse said that they would again
present at the same stage of their illness or earlier (P=0.091).
Clinical outcome
There was no difference between the groups in patients'
ratings of their health status in terms of clinical improvement after
two weeks (table 4). About 20% of the patients in each group returned
to the surgery; there was an average of two further consultations among
those who returned. About 2% of the patients in each group attended an
accident and emergency department. The study did not have enough power
to detect differences in rare outcomes such as visits to accident and
emergency departments or calls to out of hours services. Critical
events identified from the responses to the postal questionnaire and
analysis of the medical records of patients who did not return these
questionnaires found that two deaths unrelated to the presenting
problem had occurred among those who had seen a doctor; that there had
been five visits to accident and emergency in each group; that one patient who had been seen by a nurse had been admitted to hospital as
had three patients seen by a doctor; and that seven out of hours
calls had been made by those who had seen a nurse and 10 by those who
had seen a doctor.

Satisfaction
In terms of satisfaction patients rated their visits with
nurses more highly than their visits with doctors in three of four
subscales of the questionnaire. Scores of satisfaction with the nurses
were between 2 and 6 points higher than those for general
practitioners. Although this was significant, the practical importance
of such a small difference is uncertain. There was a relation between
the length of the consultation and the patient's satisfaction, but
differences in satisfaction with nurses and general practitioners
remained significant when this was accounted for. The lower ratings of
satisfaction among patients referred by a nurse to a general
practitioner may reflect the additional time patients spent waiting to
see a doctor, the inconvenience of being seen twice, or, possibly,
conflicts in the opinions of the nurse and the doctor.
The visit and clinical outcome
Nurses spent about two minutes longer with each patient
than doctors did. Although this was significant, we felt that it was
not a large difference in real terms, particularly as the role was
still comparatively new for the nurses. The extra time spent may also
have been because the nurses had a different style of consulting.
Limitations of the study
This study did not examine the content of the consultations
in detail. Although we assessed several aspects of clinical outcome,
the study did not have enough power to detect differences in rare
outcomes. We are thus not able to make any definitive statements about
the absolute safety of a service led by nurses in comparison with care
offered by general practitioners; however, patients' ratings of their
health after the visit suggest that the nurses' service was clinically effective.
Other studies
Marsh and Dawes studied a practice nurse working in a
similar role; the nurse was trained by sitting in on surgeries three
times a week for one year.2 After this, an unspecified run-in period was implemented until the nurse could perform
consultations in 10 minutes. In a study by Rees and Kinnersley, the
nurse was not trained but a nurse from outside the practice who was
also an author of the paper participated.3 It is not clear
how much experience she had in managing minor illnesses. The average
length of her consultation was 15 minutes.

What is already known on this topic
Most patients requesting same day appointments are willing to see a nurse Studies suggest that nurses can manage the care of most of these patients without the help of a doctor What this study addsThis multicentre, randomised controlled trial assessed the acceptability and safety of a minor illness service led by nurses In this study patients were more satisfied with their consultations with nurses than their consultations with doctors Clinical outcomes were similar among patients seen by nurses and those seen by doctors |
Conclusions
These results suggest that a same day appointment service
led by a practice nurse is acceptable to most patients; in this study
some satisfaction ratings were significantly higher for the nurses than
for the doctors. Our findings suggest that nurses are able to offer a
clinically effective service, although uncertainty remains regarding
rare clinical outcomes. The slightly longer time spent on consultations
is potentially a cause for concern. Reviewing the service after the
nurses have more experience running it and estimating the real cost
effectiveness outside the artificial restrictions of a trial would be
useful. It would also be interesting to study the longer term effects
of the nurses' service on patients' attitudes to their illnesses and
behaviour in seeking health care.
