Aims To make a direct assessment of the needs for mental health care in people with non-psychotic disorders consulting their general practitioner.
Method In a two-phase study design, consecutive general practice attenders aged 1765 years were interviewed using the Structured Clinical Interview for DSMIV Axis I Disorders. Needs for care were assessed using the community version of the Medical Research Council Needs for Care Assessment Schedule.
Results Three hundred and thirty-six people were interviewed. The overall prevalence of need was 27.3%. More than half of the consulters (59.6%) had unmet needs and a further 6.2% hadpartiallymet needs. Needs were met in 28.1% and unmeetable in 6.2%. The prevalence of unmet need in those with anxiety disorders was 13.9% and depressive disorders 9.5%.
Conclusions The unmet need for mental health treatment in primary care attenders is high.

The Mid Cheshire and Keele General Practice Study
The overall aim of this study was to establish the needs for treatment of
non-psychotic disorders in general practice consulters. The study was designed
to have two stages: the first was a cross-sectional survey of patients
attending their general practices, to establish the prevalence of
non-psychotic disorders and their associated treatment; the second was a
longitudinal study over 3 years of the individuals identified in the first
stage to establish their outcomes and changing needs for treatment over this
period. In this paper we report on the first stage of the study, and describe
the methodology and the prevalence of the needs for treatment of non-psychotic
psychiatric disorders found in the study practices.

Study setting
General practices in the Mid Cheshire area of England were asked to
participate in the study. The area has a mixed urban and rural population, and
covers the local boroughs of Crewe and Nantwich, Vale Royal and rural
Congleton. The central town, Crewe, developed in the second half of the 19th
century around the burgeoning railways and became the centre of the railway
industry. The surrounding area consists of older market towns, villages and
countryside. The main industries are now car and truck manufacture, salt
mining, and farming and horticulture. The total population is 280 000,
predominantly White indigenous, with ethnic minorities making up less than 2%.
Unemployment is 56.9%, income support is claimed by 6.3% of the
population and 25.9% live in one-parent households. There are 32 general
practices in the area, with an average list size of 19001999 per
general practitioner.
All 32 practices were approached and eight agreed to participate, three of which subsequently withdrew owing to work pressures. Five practices were surveyed, consisting of 21 general practitioners (11 men and 10 women) and 12 practice nurses (all women). Three of the practices were urban and the others situated in surrounding villages. The practices surveyed were smaller than those that refused to participate (mean 6227 patients v. 10 459 patients). There was no difference in the demographic profile of the doctors (mean age 40 years in study sample, 39.7 years in area; males 52% v. 57%). Seventeen per cent of the participating doctors had worked in psychiatry after qualification and 17% had been on courses of relevance to psychiatry, as opposed to 28% and 24% of those who refused. When asked to rate their interest in psychiatry as opposed to general medicine, 25% of the study doctors reported that they had the same interest in both areas, 42% rated themselves as having slightly more or much more interest in general medicine than psychiatry and 33% rated themselves as having more interest in general medicine than psychiatry, compared with 48%, 14% and 38% of those who refused.
Screening
A two-phase design was used. In the screening phase (phase I), all patients
(aged 1765 years) attending consecutive appointments with the general
practitioners and practice nurses were asked to complete the 28-item General
Health Questionnaire (GHQ28;
Goldberg & Hillier, 1979)
and provide some demographic information. A cut-off score of 4/5 was used to
identify probable cases (GHQ case). At the time of the screening
each patient completing the GHQ was asked to consent to be contacted for a
research interview. The doctor or nurse completed an encounter form for each
person screened. This form was similar to that used in previous studies
(Marks et al, 1979; Boardman, 1987): it asked the
doctor or nurse to rate the patients level of psychiatric disturbance
on a scale of 0 (no disturbance) to 5 (severe disturbance), with a score of 2
or more representing the presence of a psychological problem; such patients
were assigned to the general practitioner (GP) case group. Each
doctor or nurse was instructed on the use of the scale, but was unaware of the
patients GHQ scores. The doctors and nurses also provided basic
information on the reason for the consultation, diagnosis and immediate
management plan. All routine surgeries were screened over the course of 1
week, or until at least 40 patients from each practice had completed the
GHQ.
Selection for interview
The method used by Ormel et al
(1990) was adapted to select
the patients to be interviewed. The screened sample was divided into four
groups according to whether they were GP cases or not (GP+/GP-) and whether
they were GHQ cases or not (GHQ+/GP-) (Fig.
1). All the patients categorised as GP+ were included in the
study, whereas the other patient groups were sampled at varying rates. The
GHQ+/GP+ and GHQ-/GP+ subgroups were systematically sampled and the GHQ+/GP-
and GHQ-/GP- subgroups were randomly selected. The fraction randomly sampled
in each of the two subgroups was determined by the numbers in the GHQ+/GP+ and
GHQ-/GP+ groups. This reflects the range of participants between the maximum
(GHQ+/GP+) and minimum (GHQ-/GP+). The observed proportions can be considered
as maximum likelihood estimators if it is assumed that those who refused to be
interviewed did not differ from those who assented.

Individuals were excluded from the interviewed sample if they were known to suffer from a psychotic or organic psychiatric disorder or from a learning disability, or were not registered with the practice. All patients who agreed to be interviewed were seen in their own homes or at the surgery.
Measures
Definition of psychiatric cases
The Structured Clinical Interview for DSMIV Axis I Disorders (SCID;
First et al, 1996)
was used to classify the patients into psychiatric case groups. The SCID
questions were supplemented with questions from the Present State Examination
(PSE; Wing et al,
1974) to allow Bedford College cases of disorder to be defined
(see below).
In this study we wished to examine a broad range of cases of non-psychotic disorder in order to establish rates of these disorders and their need for treatment, thus providing data that may be of value in primary care settings. Our aim was to include a broad range of cases of non-psychotic disorder, including those consulting individuals who were not known by the GP or practice nurse to be psychologically distressed. To achieve these goals, we used standardised definitions, based on DSMIV criteria (American Psychiatric Association, 1994). The range of DSMIV disorders included major depressive disorder, substance misuse and dependence, generalised anxiety disorder, panic disorder, agoraphobia, social phobia, specific phobia, obsessivecompulsive disorder, post-traumatic stress disorder, somatisation disorder, anorexia and bulimia nervosa. No attempt was made to define Axis II disorders.
We also avoided hierarchical rules. Depressive and anxiety disorders constitute the bulk of disorders seen in primary care, and there is an overlap between anxiety and depression (Goldberg et al, 1987; Jacob et al, 1998; Sullivan & Kendler, 1998; Piccinelli et al, 1999; Tyrer, 2001). In view of this it was decided that no hierarchical rules would be applied to the DSMIV criteria, thus allowing for individuals to have two or more disorders diagnosed.
Finally, we included sub-threshold disorders. In primary care sub-threshold disorders (Pincus et al, 1999) are associated with significant impairment and high service usage (Johnson et al, 1992). To cover such levels of disorder, sub-threshold or borderline cases of anxiety and depression were recorded in addition to those meeting the standard DSMIV criteria, in order to establish a wide range of cases that might be of clinical significance to general practitioners. The category adjustment disorders was not used, following the recommendation by Pincus et al (1999). The research diagnostic criteria for minor depression as provided in Appendix B of the DSMIV manual were used (American Psychiatric Association, 1994). In addition to DSMIV defined cases, those defined by Bedford College case criteria (Finlay-Jones et al, 1980) were included. The Bedford College definitions only allow for the diagnoses of depression and anxiety to be made at the level of both case and borderline case; they were used because they allow for the inclusion of borderline anxiety states, which do not require specific diagnostic categories (such as panic disorder or specific phobia) to be specified, and these act as a wider net for anxiety disorders.
As the study progressed it became obvious that there were individuals who did not fit into any of the standard diagnostic categories but did appear to be troubled, usually by chronic difficulties. These individuals did not have sufficient symptoms to meet standard case criteria, but might have had periods of intermittent symptoms that did not reach case threshold level. These people may require some form of assistance from primary care services for their problems. Because of this we included these individuals in the study and categorised them as psychosocial cases.
Measurement of need for treatment
The Medical Research Council (MRC) Needs for Care Assessment Schedule
Community version (NFCASC;
Bebbington et al,
1996) was used to rate the needs for care. The NFCASC uses
an expert-defined or normative approach
(Bradshaw, 1972). It was
developed to assist in rating the need for care for psychiatric conditions
seen in general populations and was used in the Camberwell and Northern
Ireland studies (Bebbington et al,
1996,
1997;
McConnell et al,
2002). The NFCASC uses the same approach as the MRC Needs
for Care Assessment (Brewin et
al, 1987). The NFCASC provides a structure for the
rating of care based on information gathered at interview. Information is
required on the course and extent of symptoms and of social disability. The
decisions on which the ratings are based are clinical judgements using a panel
of experts who must reach a consensus. The rating scheme is provided in a
manual, thus enhancing agreement and reliability. Interrater reliability is
good on ratings of overall needs and specific interventions but is less good
on non-specific interventions, mainly because of differences in clinical
judgement (Lesage et al,
1996).
The original NFCASC covered seven types of disorder (positive psychotic symptoms, depressive symptoms, anxiety or obsessional symptoms, problems with alcohol, problems with drugs, eating disorders and adjustment disorders) and ratings are given for each disorder. Two criteria are required to rate a person as having a need for care: the person has significant distress from symptoms with or without disablement and this is due to some potentially remediable or preventable cause. Two rating variables are particularly important when considering the NFCASCs approach to rating need for care: items of care and primary need status. For each disorder the rating schedule specifies items of care that might be given (e.g. medication, counselling, support and cognitivebehavioural therapy) and these can be rated as not appropriate (no need), appropriate and given (met need) or appropriate and not given (unmet need). In addition, the persons own views and actions on treatment can be taken into consideration (e.g. non-compliance or rejection of the idea of treatment), as can the provision of unnecessary items of care (overprovision). In deciding on the treatments to be included in the NFCASC, Bebbington et al (1996) relied on their own knowledge and research of the psychological and pharmacological literature, and based the model on what ought to be feasible in a developed economy; the same approach has been adopted in this study.
The ratings of primary need status (the overall care need) for each disorder are based on the rating made for the items of care. If any item of care is rated as unmet then the primary need status is designated as unmet; it is thus possible for patients to receive some appropriate treatment but have their overall needs unmet. The overall ratings for this are met need (appropriate action undertaken), unmet need (appropriate action not undertaken) and no meetable need (there is disablement, but no action that is appropriate or feasible).
Bebbington et al (1996) suggested that the identification of need must rely primarily on expert opinion. This has the principal advantage that a clinical approach to deciding about treatment can be used, which matches the characteristics of the case to current evidence for treatment. When making a decision about treatment it would be uncommon for clinicians to base their judgement purely on the diagnosis; rather, they would take into account the characteristics of the individual and of the disorder, including the development and duration of symptoms, the levels of distress and impairments of social performance. This decision-making process may be particularly pertinent to primary care physicians who commonly make decisions based on the problem presenting rather than on diagnosis, which may be undifferentiated. Additionally, in a normative approach, needs can be based on treatments that are feasible in the given context and can be based on good practice rather than what is routinely provided. This expert-defined approach can take into consideration the patients own views on treatment, particularly if the patient does not wish to take up a treatment that might be offered. This acknowledges the importance of mutual collaboration between patient and clinician.
In addition to the advantages outlined above, the approach allows for a direct assessment of need. This is particularly apposite in the present context, as the entire sample consists of those consulting health services. The approach allows for aggregate estimates of need and also calculation of needs for the individuals consulting the primary health care services.
The original version of the NFCASC was modified for the purposes of our study. The following changes were made.
The treatments described as cognitivebehavioural therapy covered those embraced by the terms cognitive therapy and behavioural therapy. Thus, for depressive disorders, the term cognitivebehavioural therapy covered therapy aimed at helping individuals identify and correct their distorted and negatively biased thoughts and also interventions such as activity scheduling, social skills training, structured problem solving and goal planning. For anxiety disorders, the term covered the same approaches as for depressive disorders with the addition of techniques such as relaxation training, hyperventilation control and graded exposure.
To assist in the ratings of need for care, each participant was asked a range of supplementary questions after the SCID interview. These covered the details of the consultation on the day of screening, current treatment (and planned treatment, e.g. referrals already made to psychiatric services) and treatments received in the past year. Participants were also asked what treatments they would accept for their current problem. This information was elicited through the use of a single open question and a checklist of possible treatments, including medication, psychological therapy, referral and alternative (complementary) therapies.
All participants who were selected for needs rating were discussed at a regular rating meeting, attended by the authors and two psychiatric nurses who had worked in general practice, when each item was rated on a consensus basis. The ratings of the primary needs status, assessment of items of care and overprovision were made as in Bebbington et al (1996). If any one item of care was rated as unmet then the primary need status was rated as unmet. People who were diagnosed as having more than one disorder had needs rated for each disorder (diagnostic/symptom area).
All screening and interviews were done by research assistants (two of whom were psychiatric nurses) who were trained to complete the interviews and ratings. The research diagnostic criteria were applied by the interviewers and in the consensus rating meetings. All needs ratings were made in the consensus rating meetings.
Analysis
The prevalence figures were calculated using the sampling proportions
(those screened for interview/those interviewed for each of the four GHQ/GP
groups) as weighting factors (see Fig.
1), in the same manner as that described by Ormel et al
(1990). The results were
analysed using the Statistical Package for the Social Sciences (SPSS for
Windows) and are reported as prevalence rates (per 1000 attenders).

Interviewed sample
Four hundred and ninety individuals were selected for interview and 336
(69%) were successfully interviewed (Fig.
1). The demographic details of the people who accepted interview
were not significantly different from those who refused interview, except that
they were slightly older (43.7 years v. 39.1 years) and were more
likely to be married and less likely to be single (interviewed: 15% single,
72% married; refused: 25% single, 62% married). Two-thirds of the interviewed
sample (66.1%) were women. Of the sample, 64.3% were employed, 14.6%
unemployed, 15.5% worked in the home, 4.2% were students and 1.5% disabled;
25.9% belonged to social class I/II, 46.5% to III and 27.4% to IV/V. All were
White and 98.5% had been born in the UK.
Prevalence of psychiatric disorder
Of the individuals interviewed, 147 (43.8%) were eligible for definition as
a case of psychiatric disorder on at least one of the case definitions used.
After application of weighting factors, this gives a total prevalence of 279
per 1000 consulters (Table
1).
|
A DSMIV disorder was present in 105 participants and a further 17 had minor depression only. The total prevalence of DSMIV disorders was 190 per 1000 (95% CI 148232) 217 per 1000 (95% CI 173261) if minor depression is included. Anxiety disorders (prevalence 117 per 1000, 95% CI 83151) and depressive episodes (prevalence 151 per 1000, 95% CI 113189) constituted the bulk of the disorders seen (see Tables 3 and 4). The most common single categories were major depressive episode (prevalence 108 per 1000) and generalised anxiety disorder (prevalence 77 per 1000). Other disorders were relatively uncommon (Table 2). The majority (58%) of all DSMIV cases met criteria for only one DSMIV diagnostic category (60% if minor depression is excluded).

|
One hundred and twenty-nine participants met the Bedford College case criteria. The total prevalence of Bedford College cases was 235 per 1000 (95% CI 190280). Only depression and anxiety were included in this case definition and borderline anxiety was the most common diagnosis (prevalence 147 per 1000). There were only five psychosocial cases in the sample, giving a prevalence of 15 per 1000.
Needs for care
The 147 participants who met the conditions for definition as a current
case on the broad criteria used (including psychosocial) were
included in the analysis. Of these, 81 (55.1%) had only one diagnostic/symptom
area rated, 61 (41.5%) had two areas rated, 4 (2.7%) had three areas rated and
1 had five areas rated. The number of participants rated in each area is shown
in Table 2. The 147 patients
had a total of 220 diagnostic/symptom areas rated.
Overall need for care
The overall needs for care in the 147 cases are shown in
Table 1. These were calculated
from all the 220 diagnostic/symptom areas rated, taking into consideration
whether the primary need status for each area was rated as met, unmet or not
meetable. This allowed for needs to be considered as fully met (i.e. met in
all diagnostic/symptom areas rated), partially met (met in at least one of the
diagnostic/symptom areas, but not all those rated), or not met (not met in any
of the diagnostic/symptom areas rated). Those shown as having no meetable need
were all people who did not want any intervention.
Only one person was thought to have no need for any intervention (a patient with generalised anxiety disorder). Thus the overall prevalence of need was 273 per 1000 consulters. The majority of the individuals with need had unmet needs (59.6%) and a further 6.2% had needs met in at least one diagnostic/symptom area on which they were rated (partially met needs). Nine people had needs that could not be met because they did not want any form of intervention.
Needs for care for individual disorders/symptom areas
The overall needs for care for the individual diagnostic/symptom areas are
shown in Table 2. The column
overprovision has been added to show those individuals who
received an item of care that was seen by the rating panel to be in excess of
usual treatment. Individuals entered in this column have been double-counted
and are also included among those in the other columns, as many of them had
their needs met.
The prevalence of unmet need was higher in anxiety than in depression (139 per 1000 v. 95 per 1000). The needs for care of people with the less common disorders were always unmet. This did not mean that the individuals with these disorders did not receive any treatment; rather, they had some item of care rated as appropriate, but not given (unmet). For example, all four people with obsessivecompulsive disorder received psychotropic medication but only two of the four were given cognitivebehavioural therapy. All four were thought to require referral to psychiatric services, but only two had actually been referred. Only one of the cases of somatoform disorder had been recognised by the general practitioner, and this patient had been given cognitivebehavioural therapy. Only one of the cases of substance misuse was known to the general practitioner, and this patient had received psychological therapy. Both of the people with eating disorders had received cognitivebehavioural therapy in the past, but it was currently thought that both would benefit from a referral to psychiatric services. Only two of the five psychosocial cases had been acknowledged by the general practitioner.
Anxiety and depression
The treatment needs of the participants with depressive disorders are shown
in Table 3. The highest
prevalence of unmet need was for DSMIV major depressive disorder (71
per 1000). The proportion of cases of major depressive disorders was higher
than for minor depression, but this difference was not significant
(2=2.559, P=0.278). The treatment needs of those with
anxiety disorders are shown in Table
4. The prevalence of unmet need was highest in those with Bedford
College borderline anxiety (106 per 1000). The proportion of those whose needs
were met varied across the specific categories of DSMIV anxiety
disorders. No case of specific phobia had needs met; and only one case each of
agoraphobia and of post-traumatic stress disorder had needs met.
The two most frequently rated items of care that were thought to be required for depression were medication (rated appropriate in 85% of cases) and cognitivebehavioural therapy (rated appropriate in 65% of cases). Of the 62 patients with depression for whom the latter therapy was thought to be appropriate, 44 (71%) were not receiving it, 7 (11%) rejected the idea of such therapy and 11 (18%) had received it. In the 82 cases of depression in which the patient was thought to need anti-depressant medication, 23 (28%) were not receiving it, 9 (11%) did not want it and 50 (61%) had received it.
For depression, the items of care for which need was most frequently assessed as being unmet were cognitivebehavioural therapy (45%), medication (24%), assessment (24%) and general practitioner acknowledgement (18%). The equivalent figures for anxiety were: cognitivebehavioural therapy 55%, assessment 49%, general practitioner acknowledgement 45% and medication 13%.
Medication (65/108; 60%) and cognitivebehavioural therapy (85/108; 79%) were also the two most frequently rated items of care thought appropriate for anxiety. Of the 85 patients with anxiety for whom cognitivebehavioural therapy was thought appropriate, 59 (69%) were not receiving it and 10 (12%) rejected it. Of the 65 patients with anxiety thought to require medication, 14 (21%) were not receiving it and 4 (6%) did not want it.

Methodological considerations
The study was conducted with attention given to the sampling procedure and
was in line with the two-phase process used by others
(Dunn et al, 1999).
The specific sampling procedure was based on that used by Ormel et al
(1990), but did not sample
new and old patients separately. In addition, in
our study the GP-/GHQ- and GP+/GHQ+ fractions were randomly selected, whereas
in the Ormel study these were sampled by taking every fourth subject
(GP-/GHQ+) and all subjects until the second patient per doctor had accepted
(GP-/GHQ-). We believe that our approach offers a refinement to the Ormel
et al method.
The practices were not randomly chosen and were selected on the basis of their agreement to assist. This may affect the rigorous quality of the results. However, both urban and rural practices were used, which represented the range of populations in Mid Cheshire. The participating general practitioners appeared to be typical of the others in the area, but the practices were generally smaller than the average for the area. This may reflect the problem of getting all the doctors in any one practice to agree to participate in such a study, and may also reflect the perceived time pressures on the doctors. Patients attending both doctor and nurse appointments were used to generate the interviewed sample. This broadened the range of patients included, although in practice the bulk of cases came from those consulting the doctors.
We chose to consider a broad range of cases of non-psychotic disorders, including borderline cases, as we wished to reflect a sample that might have clinical relevance for general practitioners. The cases were all operationally defined, thus allowing for replication. All cases but one were thought to require intervention ranging from acknowledgement of the patients problems by the general practitioner to referral to psychiatric services. No hierarchy of diagnoses was applied, thus many of the cases had mixed disorders (mainly anxiety and depression). We did not assess the overall need for treatment of the patients in these mixed cases and judged treatment for each disorder separately. The figures quoted for individual diagnoses are for disorders, not individuals, although the overall needs (see Table 1) are those of the individuals in the study.
Judging treatment needs from an expert point of view may be unreliable, because clinicians will vary in their assessments. We approached this problem by making judgements by consensus, using several raters who took into consideration the clinical details, the context and the available evidence. In addition, a record of previous decisions was made so that consistency between ratings could be achieved. The view of the patient was considered separately and reflected in the rating of no meetable need if the patient did not want the treatment thought to be desirable by the experts. The patients view of treatment needs is complex, and patients may accept one treatment but reject another. Most patients said they would accept treatments if offered, but some rejected them on the basis of past experience. Patients acceptance of treatment is likely to change over time, as are their needs and whether these needs are met. This is not adequately reflected in this cross-sectional study and we are now in the process of following up the interviewed sample.
The approach adopted here is time-consuming, but it is flexible as additional ratings can be added depending on the nature of the study.
Overall prevalence of disorder
The overall prevalence obtained in the Cheshire practices sits within the
range of nine studies quoted by Vázquez-Barquero et al
(1999): 1538.8%. The UK
study by Blacker & Clare
(1988) gave an overall rate of
35.5%, but included adjustment disorders in this figure; when these are
removed the rate falls to 17.4%. Because of the use of different criteria and
the brief way in which the Blacker & Clare data were reported, it is
difficult to compare them accurately with our results. It is likely that some
of the adjustment disorders included in their sample contained the types of
disorders covered by the borderline/sub-threshold categories in our study. The
Blacker & Clare study was also conducted in an inner-city practice, where
higher rates of disorder might be expected.
Level of need
In only one case of disorder was the individual thought not to require any
treatment. This is a rate much lower than that found in equivalent community
studies (e.g. Bebbington et al,
1997) and probably reflects the fact that our sample was recruited
from those consulting in primary care. Five people did not meet the criteria
for definition as cases either on the DSMIV or Bedford College
criteria, but were individuals who were thought to have needs for treatment.
These individuals were defined as having psychosocial disorders,
and would have been categorised as non-cases in other studies of
need, which employed operationally defined diagnostic criteria. The Camberwell
Needs for Care study did rate some people who were not identified as
cases as having a need for care
(Bebbington et al,
1997).
Some of the individuals who were rated as having a primary unmet need for care might have been receiving some appropriate treatment, but because of the way in which the primary need was defined it does not reflect this receipt of treatment. However, many of those rated as having a primary unmet need were not receiving any treatment, and those who received isolated items of care should be considered as being in receipt of an inadequate package of care. These missing items of care may be given over time and, if so, should be picked up in the follow-up study.
Comparison with other findings
The only comparable UK studies investigated community samples, and showed
low levels of met need and low rates of consultation with primary care
services (Bebbington et al,
1997,
1999,
2000a,b).
Comparison of our results with these community studies suggests that visiting
the general practitioner does not ensure that needs will be met. The
Camberwell Needs for Care study reported on the needs met in people who had
contacted their general practitioner in the previous year
(Bebbington et al,
1999): 54.5% had unmet needs, 13.6% had their needs met and 4.5%
had unmeetable needs. This sample was small (n=22), but the findings
are similar to those in our larger sample.
Generalisability of the findings
The actual prevalence rates quoted will inevitably reflect the base
population from which the participants were recruited, and the proportions of
met and unmet need will reflect the availability of services. Mid Cheshire is
a mixed urban and rural area with a substantial White working-class
population. The quality of general practice is good. This is not substantially
different from many areas in England, although it is certainly different from
the major innercity centres. The findings may thus reflect the prevalence of
psychiatric disorders in many UK general practices. There is nothing
exceptional about the psychiatric services in Mid Cheshire and no reason to
believe that the availability of specific treatments is different from other
parts of the country.
Implications
There is good evidence for the efficacy of treatments for non-psychotic
mental disorders (Nathan & Gorman,
1998). Our findings suggest that the bulk of people with common
mental disorders who visit their general practitioner are not receiving
treatments of proven efficacy and this does not appear to be related to their
willingness to accept such treatment. The majority of the people with anxiety
and depression could be treated in primary care if sufficient expertise were
available, and some could be managed entirely by their general practitioner
with good clinical care
(Andrews, 1993) and possibly
the use of medication. Many require psychological therapies, some of which
could be delivered by computerised systems
(Proudfoot et al,
2003) or by group methods such as those tested on non-consulting
samples (Brown et al,
2000; Watkins et al,
2000). Additional self-help approaches could also be of benefit to
these individuals.
Delivery of such approaches in primary care would require the appropriate training of general practitioners and other primary care workers in consultation techniques designed to improve detection of psychological disorders (Gask et al, 1991), greater awareness of the value of medication, and possibly of cognitivebehavioural techniques such as structured problem solving and event scheduling (Andrews, 2001). Provision of cognitivebehavioural therapy primary care may be difficult to achieve given the lack of trained therapists (Goldberg & Gournay, 1998), and other potentially cost-effective methods of delivering psychological therapies need to be considered and evaluated (for example, Brown et al, 2000; Watkins et al, 2000; Proudfoot et al, 2003). Many of the disorders identified in this study are chronic and recurrent, and an enhanced care approach might be beneficial in the longer term (Von Korff & Goldberg, 2001). The necessity for secondary care remains much as it is at present, but allowing patients access to effective treatments in primary care will need not only the enhancement of the skills of primary care workers, but also the creation of new and effective working relationships with mental health professionals.
