System failure? The problems of reductions in long-stay beds in the UK

OBJECTIVE

To review the relevant literature on the effects of reductions in long stay beds on mental health services in the UK.

METHOD

A selective literature review, with particular reference to research conducted by the author and colleagues at The Sainsbury Centre for Mental Health.

RESULTS

The evidence suggests that the effects of long stay bed reductions should be examined with regard to 'old' and new long stay patients separately. While the 'old' long stay who have been most directly effected by these changes have generally fared well; the 'new' long stay have not. They are currently accumulating in acute inpatient units, often on general hospital sites, or are rotating in the 'revolving door' of acute inpatient care and inadequate community supports. Although it is clear that there is a shortage of acute beds especially in inner city areas many of the these beds are currently occupied by patients who would be better (and less expensively) cared for in community alternatives if these were available. The evidence suggests that it is possible to improve outcomes for this 'new' long stay group if specific kinds of housing, work and assertive community teams are provided.

CONCLUSIONS

It is concluded that the effects of long stay bed reductions should be considered in a 'systems perspective. Effective community services can be established, but in order to achieve effective substitution of one kind of service for another, there must be a well co-ordinated, clearly targeted, and technically efficient system. At the present time such services are rare. However, simply focusing on one element (e.g. beds) is unlikely to produce cost effective and efficient solutions.

Randomised controlled trial of compliance therapy. 18-month follow-up

BACKGROUND

A randomised controlled trial was conducted in an acute treatment setting to examine the effectiveness of compliance therapy, a brief pragmatic intervention targeting treatment adherence in psychotic disorders, based on motivational interviewing and recent cognitive approaches to psychosis.

METHOD

Seventy-four patients with psychotic disorders according to DSM-III-R criteria recruited from consecutive admissions to an acute in-patient unit, received 4-6 sessions of either compliance therapy or non-specific counselling, and were followed-up over 18 months. The principal outcome measures were observer-rated compliance, attitudes to treatment, insight and social functioning.

RESULTS

Significant advantages were found for the compliance therapy group post-treatment on measures of insight, attitudes to treatment and observer-rated compliance which were retained over the follow-up period. Global social functioning improved relatively more over time in the compliance therapy group compared with the control group. Survival in the community prior to readmission was significantly longer in the compliance therapy group.

CONCLUSIONS

The results support the effectiveness of compliance therapy in improving functioning and community tenure after an acute psychotic episode.

London-East Anglia randomised controlled trial of cognitive-behavioural therapy for psychosis. I: effects of the treatment phase

BACKGROUND

A series of small, mainly uncontrolled, studies have suggested that techniques adapted from cognitive-behavioural therapy (CBT) for depression can improve outcome in psychosis, but no large randomised controlled trial of intensive treatment for medication-resistant symptoms of psychosis has previously been published.

METHOD

Sixty participants who each had at least one positive and distressing symptom of psychosis that was medication-resistant were randomly allocated between a CBT and standard care condition (n = 28) and a standard care only control condition (n = 32). Therapy was individualised, and lasted for nine months. Multiple assessments of outcome were used.

RESULTS

Over nine months, improvement was significant only in the treatment group, who showed a 25% reduction on the BPRS. No other clinical, symptomatic or functioning measure changed significantly. Participants had a low drop-out rate from therapy (11%), and expressed high levels of satisfaction with treatment (80%). Fifty per cent of the CBT group were treatment responders (one person became worse), compared with 31% of the control group (three people became worse and another committed suicide).

CONCLUSIONS

CBT for psychosis can improve overall symptomatology. The findings provide evidence that even a refractory group of clients with a long history of psychosis can engage in talking about psychotic symptoms and their meaning, and this can improve outcome.

Overview of severe mental illness

The severe mental illnesses are psychiatric disorders characterized by their persistence and extensive disability. Classification of these disorders has seen improved reliability, but problems remain with validity. Etiological formulations emphasize the biological origins of the disorders, but psychological factors, chiefly in the area of stress, are recognized as important in the management of relapse. Psychological features, especially those apparent during psychotic episodes, make the disorders particularly difficult to treat. Patients tend to be noncompliant. In addition, these features dispose people with severe mental illnesses to behaviors that place them at risk for HIV and other catastrophic illnesses. New psychopharmacological treatments may improve compliance and reduce relapse, but none has made psychosocial treatments unnecessary. Progress in developing effective treatments has been slow, but prospects are encouraging.

Cognitive therapy and recovery from acute psychosis: a controlled trial. II. Impact on recovery time

BACKGROUND

A trial of CT in acute psychosis conducted by the authors has shown a significant impact on the rate and degree of recovery of positive symptoms, the focus of the intervention. This paper seeks to determine whether these effects generalise to other features of acute psychosis including dysphoria, insight and "low level' psychotic thinking which were not directly targeted.

METHOD

Measures of dysphoria, insight and psychotic thinking were taken over a six-month period following presentation for acute psychosis. Using survival analysis, time to recovery from psychosis using three definitions of increasing stringency was compared between the CT and control group.

RESULTS

CT was associated with a 25-50% reduction in recovery time depending on the definition used.

CONCLUSION

The impact of the CT intervention extended beyond positive symptoms to include insight, dysphoria and "low level' psychotic thinking. Nevertheless this kind of "clinical' recovery required a median of 20 weeks to complete. Implications for clinical models of acute care are discussed.
