Abstract
Most of the studies that are frequently cited as examples of effective comprehensive community care, (i.e. they reduce the demand for hospital beds without any loss in treatment efficacy (Stein & Test, 1980; Hoult & Reynolds, 1984; Muijen et al., 1992) were carried out before the introduction of the Care Programme Approach (CPA) in 1991 (Department of Health, 1990) which at present only applies to England. As the CPA derives from these earlier studies the discrepancies between hospital and community based aftercare might be expected to become less, as now all services in England are expected to include a significant community element. However, there can still be important differences between those services focusing on community care as the main priority and those in which the hospital system is paramount.The psychiatric services in the area covered by North West London Mental Health Trust (NWL Trust) represented a natural test of these two approaches as they had parallel hospital and community based teams covering the same catchment areas respectively, North Paddington, in Westminster and Brent, in outer London.At this point it is useful to provide more detailed description of the two geographical areas at the time of the study and the community and hospital based teams that were involved.

Abstract
This study investigated the properties of a novel piperidine ether-based tachykinin NK1 receptor antagonist L-733,060, ((2S,3S)-3-((3,5-bis(trifluoromethyl)phenyl)methyloxy)-2-phenyl piperidine and its 2R,3R-enantiomer L-733,061 on [Ca2+]i mobilisation in Chinese hamster ovary cells transfected with human tachykinin NK1 receptors, compared to their effects in rodent cardiovascular and neurogenic plasma extravasation assays. Using FURA-2-imaging techniques, L-733,060 inhibited substance P-induced [Ca2+]i mobilisation with an estimated affinity of 0.8 nM whereas L-733,061 (30-300 nM) did not. No significant effects of L-733,060 were observed on mean arterial blood pressure or heart rate in conscious or anaesthetised rats at doses of < 3000 micrograms kg-1 i.v. L-733,060 also stereoselectively inhibited neurogenic plasma extravasation in rat dura produced by electrical stimulation of trigeminal nerves with an ID50 of 212 +/- 19 micrograms kg-1 i.v. Thus, L-733,060 is a novel antagonist of human tachykinin NK1 receptors which stereoselectively inhibits neurogenic plasma extravasation at doses that do not cause adverse cardiovascular effects.

Abstract
OBJECTIVE The authors developed a simplified method of rating the severity of personality disorder. METHOD The new rating method is based on four levels of severity: no personality disorder, personality difficulty, simple personality disorder, and diffuse personality disorder. The new method was applied to different diagnostic systems and was then compared with an old rating system based on six severity levels. Data were derived from a longitudinal study in which 163 patients with anxiety and depressive disorders had initial assessments of personality status and were followed up over 2 years. Ratings of psychiatric symptoms were made by using the Comprehensive Psychopathological Rating Scale over this period. The results were analyzed with special attention to linear and quadratic trends. RESULTS The new system was clinically useful in separating patients' initial assessments and outcomes. Patients with no personality disorder had the lowest initial symptom scores and the best outcomes, and those with diffuse personality disorder had the highest initial levels of symptoms and improved least over the 2 years. When the patients were separated by the old classification system, 72% of the variation between groups was accounted for by linear and quadratic trends; the comparable percentage was 97% when the patients were categorized by the new system. CONCLUSIONS The new system of rating severity of personality disturbance is an improvement on existing methods and allows ratings to be made easily from DSM-IV and ICD-10.

Abstract
Cognitive therapy for affective disorders has been recently adapted and developed for the treatment of personality disorders. In the present study, a specific and detailed cognitive therapy treatment manual for borderline and antisocial personality disorders was evaluated in a pilot study. The results of a single case series demonstrate that important clinical changes in dysfunctional behaviour and attitudes can be achieved with short-term cognitive therapy in patients with antisocial and borderline personality disorders, although these were not, on the whole, statistically significant.

Abstract
The satisfaction of general practitioners with a community mental health service operating an open referral system was compared to that with two services both operating a closed referral system covering the same inner-city district. The open referral system allows any agency (including patients) to contact the service by letter or by telephone, and priority is given to patients with serious mental illness. General practitioners' satisfaction with all aspects of the open referral system was greater than that with either of the closed referral systems. In particular, speed of assessment of referrals was preferred in the open referral system.

Abstract
This study aimed to compare the costs of treatment by community-based and hospital-based psychiatric services. The design entailed random allocation of patients presenting with psychiatric emergencies over a subsequent 3-month period to one of two services, followed by retrospective quantification of service use and its cost for each group. One hundred patients with emergency presentations to the psychiatric service via the Accident and Emergency Department, liaison psychiatrist and approved social worker were included in the study. Their use of a range of terms of service was recorded and disaggregated costings of these items of service was calculated. The use of non-psychiatric services was similar for both groups, but the use of psychiatric services differed, with the hospital group making greater use of in-patient beds and the community group employing more frequent home-based interventions. The total cost of treatment for the community group (pound 56,000) was much lower than for the hospital group (pound 130,000), although the median patient cost was 50% higher in the community group (pound 938 v. pound 610), and a greater proportion of the community service expenditure (10% v. 2%) was due to failed contacts. Taken together with clinical outcome, which showed no advantages for the hospital-based service over the community-based service, our findings suggest that this form of community psychiatric service is a cost-efficient alternative to hospital-based care for this group of patients.

Abstract
BACKGROUND In previously published papers from the Nottingham Study of Neurotic Disorder a short treatment package of cognitive-behaviour therapy was no more effective than placebo drug treatment after 10 weeks' assessment in a cohort of 210 patients with neurotic disorders. This paper examines the outcome over two years of the patients treated by cognitive-behaviour therapy separated into two therapist groups, those who were competent in administering treatment and those of uncertain competence. METHOD The therapists (mainly community psychiatric nurses) of 70 patients with an original DSM-III diagnosis of either dysthymic, panic or generalised anxiety disorder were separated into two groups on the basis of their perceived competence by their supervisor (DK). Ratings of psychopathology were made at regular intervals over two years by assessors blind to knowledge of treatment or therapist. RESULTS The patients treated by competent therapists (n = 30) generally showed greater improvement than those allocated to therapists of uncertain competence (n = 40), mainly with respect to depressive symptoms, and the difference persisted over two years, long after the cognitive-behaviour therapy had been completed. CONCLUSIONS Cognitive-behaviour therapy given by competent therapists over a 10 week period is of lasting benefit in neurotic disorder.

Abstract
Social phobia has been recognized only recently as a clinical entity, and there is considerable overlap in diagnosis between agoraphobia, panic disorder, stress disorder and avoidant (anxious) personality disorder. In more severe cases there may also be some difficulty in differentiating the condition from schizophrenia. In reaching a correct diagnosis of social phobia it appears that the two essential elements of a phobic diagnosis, situational fear and avoidance, should be present prominently and that a distinction from agoraphobia can be made by paying close attention to the nature of the situations in which fear is shown. If this policy is followed, social phobia can be readily defined and is fairly easily distinguished from other neurotic disorders. There is considerable overlap with the anxious and fearful group of personality disorders, particularly avoidant (anxious) personality disorder and this is almost impossible to distinguish from chronic persisting social phobia. Data are presented on the incidence of primary and secondary social phobia occurring prospectively in patients with the most common neurotic disorders (dysthymia, panic and generalized anxiety disorder) seen over a 2-year period. Twelve per cent of the patients had secondary social phobia initially, but over the 2-year period 9% of the patients had social phobia as a primary or single psychiatric diagnosis on at least one occasion. This was most likely in those patients allocated to a benzodiazepine, diazepam, in the first phase of treatment (p < 0.05).

Abstract
BACKGROUND The possibility that treatment with tricyclic antidepressants, in the form of dothiepin, might attenuate benzodiazepine withdrawal symptoms was investigated in a double-blind trial. METHOD Eighty-seven non-depressed psychiatric out-patients with putative normal dose benzodiazepine dependence had their benzodiazepines reduced in stepwise amounts of 20% of the original dose for eight weeks. The patients were randomised to receive dothiepin (with dosage increasing to 150 mg/day) or placebo as an aid to withdrawal before benzodiazepine reduction and these drugs were taken for four further weeks before being stopped. RESULTS Fewer patients entered and completed the study than expected and a Type II error was possible in the results. Although there was some evidence of withdrawal symptoms being less marked in those patients allocated to dothiepin this was independent of any antidepressant effect as depression scores were lower in the placebo group in the early phase of withdrawal (P < 0.01). Of those completing the study, greater satisfaction (P = 0.03) was recorded by those who had received dothiepin; no other differences reached statistical significance. CONCLUSIONS Dothiepin (and by implication other tricyclic antidepressants) might have some value in reducing benzodiazepine withdrawal symptoms but does not aid drug withdrawal.

Abstract
Ten long-term users of benzodiazepines (average daily dose, 20 mg of diazepam or equivalent) who had experienced problems in withdrawing from the drugs were given an i.v. challenge with either the benzodiazepine antagonist flumazenil (1 mg injected over 30 s) or placebo (vehicle solution) in a randomized double-blind design. There were no 'pseudo withdrawal' responses to either single-blind or double-blind placebo injections, whereas flumazenil produced dramatic panic reactions in all four subjects tested, followed by characteristic benzodiazepine withdrawal symptoms. There were also small but significant rises in pulse rate and blood pressure, but no change in serum cortisol. Flumazenil-induced panic could not be entirely accounted for by a past or present diagnosis of panic disorder, and did not seem to be related to previous withdrawal problems, present benzodiazepine dosage, or to the severity of withdrawal symptoms precipitated by flumazenil in the same challenge test. Attempts to reduce benzodiazepine intake over the next 3 weeks tended to be more successful in the flumazenil group. The results are discussed with reference to possible changes in the GABA-benzodiazepine system in long-term benzodiazepine users.

Abstract
The care programme approach was introduced in mental health services in the UK in 1991. It was intended to improve the quality of care and prevent patients losing contact with care services and, by implication, to reduce psychiatric admissions. We did a study to find out if the approach worked. 400 patients from a London inner-city area who had been identified as psychiatrically vulnerable and included on a case register of patients with special needs were randomised into two groups of 200 each. One group received close supervision by nominated key-workers (as recommended in the care programme approach of the UK Department of Health), and the other received standard follow-up from psychiatric and social services. Outcome was recorded after eighteen months. Data on 393 patients was available for analysis. Of 197 patients allocated to standard care, 64 (32.5%) were lost to follow-up compared with 40 (20.4%) of 196 patients receiving close supervision (p = < 0.005). However, patients under close supervision had significantly more admissions (30% vs 18%, chi 2 = 7.61, p < 0.01) and spent 68% more days in hospital than the standard group. The findings of greater hospital-bed use, which differ from those of studies with community-based psychiatric teams, suggest that close supervision by a single key worker, as recommended in the care programme approach, will lead to greater success in maintaining contact with vulnerable patients, but is likely to lead to more psychiatric admissions.

Abstract
One hundred psychiatric emergencies presenting to an inner London teaching hospital had formal assessments of psychopathology, personality disorder (using both ICD-10 and the Personality Assessment Schedule), social networks and social functioning before being randomly assigned to a multidisciplinary community-based team (Early Intervention Service (N = 48) or conventional hospital-based psychiatric services (N = 52) and treated for a period of 12 weeks. The ICD-10 classification yielded a higher proportion (50%) of personality disordered patients than the Personality Assessment Schedule (34%) and those from ethnic minorities (mainly Afro-Caribbean) and upper social classes had a lower incidence of personality disorder. Social networks were smaller in personality disordered patients and there were fewer attachment figures. Improvement in social function, and to a lesser extent with depressive symptomatology, was better in patients with no differences were found between the numbers and duration of social contacts in the two services and it is concluded that the better outcome in the community-treated patients was independent of changes in social networks.

Abstract
It is argued that the usefulness of borderline personality disorder in clinical and research practice is largely because the borders of the diagnosis are so flexible. The diagnosis overlaps with other personality disorders, disturbances of mood and intermittent abnormal behavior. As almost all behavior likely to lead to consultation with mental health professionals is included among the elements of personality disorder, it is not surprising that it is almost the most common condition seen by specialists in the field. An attempt is made to define the borders of the condition in this review. It is concluded that these are so far-reaching that they negate the notion that borderline conditions are personality disorders. It is argued that the borderline state is a coaxial diagnosis of personality and mental state disorder and to continue to describe the concept as a personality disorder is wrong and misleading.

Abstract
Benzodiazepine dependence is a frequent complication of regular prescriptions for 4 weeks or longer, occurring in almost one-third of patients. Although it is also manifested by tolerance to drug effects and occasional drug seeking behaviour, particularly in those prone to drug abuse, most dependence is characterised by a withdrawal syndrome on stopping treatment. The withdrawal syndrome includes symptoms of anxiety and those of perceptual disturbance such as depersonalisation, hypersensitivity of all major senses, dysphoria and (rarely) epileptic seizures and psychotic episodes. Risk factors for dependence include high dosage, use of more potent and short acting benzodiazepines, long duration of therapy and dependent premorbid personality characteristics. If none of these apply, benzodiazepines can be prescribed with safety.

Abstract
The first 590 patients referred to a community mental health service (the Early Intervention Service) in an inner-city district were separated into groups based on their referral source. The service has an open referral system allowing any agency (including patients) to contact the service by letter or by telephone, and priority is given to patients with serious mental illness. The results of open referral showed that the number of referrals was adequate for the service to process, the proportion of inappropriate referrals was similar in all referral agencies, and milder cases of mental illness were referred more often from doctors than from other agencies. It is concluded that an open referral system is likely to be more sensitive to need and has some advantage over closed referral arrangements in inner-city areas.
