Quality of life outcome in a randomized controlled trial of case management

BACKGROUND

This paper presents the quality of life (QOL) outcome results from the UK700 randomised controlled trial of case management.

METHOD

A total of 708 patients with severe mental illness were randomly assigned to intensive and standard forms of case management in four sites in the UK. QOL was assessed using the Lancashire Quality of Life Profile, which provides a self-reported objective and subjective appraisal of eight life domains (finances, work, leisure, family, social relations, living situation, safety and health). The outcome after 2 years was examined using univariate and multivariate analyses.

RESULTS

Significant improvements in QOL over the 2 years were observed. The QOL outcome did not differ significantly by case management treatment conditions or by diagnosis. A better outcome was associated with improvements in depression and with the location (site) of treatment. In one site there were significant improvements in all eight domains and overall QOL, with moderate or better effect sizes (> 0.4) in three domains and overall QOL.

CONCLUSIONS

Depression should be assessed when subjective QOL measures are used. Better means for describing service organisations and the context/place in which they operate should be developed in order to explain more of the variance in QOL outcomes.

Relatives of patients with severe psychotic disorders: factors that influence contact frequency. Report from the UK700 trial

BACKGROUND

The isolation experienced by many patients with severe psychotic disorders is generally assumed to be due to their social withdrawal. An alternative possibility is that relatives avoid frequent contact with patients because they find the situation distressing.

AIMS

To examine the predictors of frequent patient-relative contact, in particular the role of relatives' experience.

METHOD

UK700 trial data were used to determine baseline predictors of frequent contact and establish whether relatives' experience at baseline predicted continued frequent contact 2 years later.

RESULTS

Neither characteristics associated in the literature with relatives' 'burden' nor relatives' experience predicted patient-relative contact frequency. Instead, the predictors were mainly demographic.

CONCLUSIONS

Many relatives experience considerable distress, but the evidence does not suggest that they avoid frequent contact with the patient as a consequence.

Day centres for severe mental illness

BACKGROUND

The number of people with severe mental illness who receive treatment whilst living at home has increased greatly over the last 30 years. Day centres and day hospitals frequently supplement this treatment.

OBJECTIVES

To determine the effects of non-medical day centre care for people with severe mental illness.

SEARCH STRATEGY

The Allied and Complementary Medicine Database (1985-1999), The British Nursing Index (1994-1998), The Cochrane Library (Issue 2, 1999), The Cochrane Schizophrenia Group's Register (May 1999), EMBASE (1980-1999), MEDLINE (1966-1999), PsycLIT (1887-1999), The Royal College of Nurses Database (1985-1996), and Sociological Abstracts (1963-1999) were searched. References of all identified studies were also inspected for more studies.

SELECTION CRITERIA

All randomised controlled trials where seriously mentally ill people were allocated to non-medical day centre care.

DATA COLLECTION AND ANALYSIS

Studies were reliably selected, quality rated and data extracted. For dichotomous data, it had been hoped to estimate the Peto odds ratios (OR) with 95% confidence intervals (CI) and the number needed to treat statistic (NNT). Analysis was to have been by intention-to-treat. Normal continuous data were to have been summated using the weighted mean difference (WMD) and scale data presented only for those tools that had attained pre-specified levels of quality.

MAIN RESULTS

Despite extensive searching, no trials were found of non-medical day centres. The electronic search identified over 300 citations but none was relevant to this review.

REVIEWER'S CONCLUSIONS

The reviewers feel that the inclusion of any studies less rigorous than randomised trials would result in misleading findings and that it is not unreasonable to expect well designed, conducted and reported randomised controlled trials of day centre care. More precise nomenclature would greatly help identify relevant work. At present non-randomised comparative studies give conflicting messages about the roles provided by day centres and the clinical and social needs they are able to meet. It is therefore probably best that people with serious mental illness and their carers, if given the choice, take a pragmatic decision on which type of unit best meets their needs. There is a clear need for randomised controlled trials of day centre care compared to other forms of day care, such as day hospitals.

Home treatment

BACKGROUND

Deinstitutionalisation has stressed where care is no longer taking place. Home treatment in rehabilitation reflects the steady increase in emphasis on support and treatment for individuals with long-term disorders where it matters for them--in their own homes.

MATERIALS AND DISCUSSION

Whether dealing with individuals discharged after long periods in hospital or with the increasing number who have experienced repeated short-term admissions, most modern day rehabilitation takes place in the patients' homes and neighbourhoods. We are increasingly convinced that this decentralisation is a positive strength, not a problem. Its advantages include improving social inclusion and the ability to conduct more accurate, personalised assessments of disabilities and strengths. Skills training is more focused and we discuss the components of home treatment and assertive community treatment as they are relevant to rehabilitation. This involves both medication and practical help, brokerage and involvement with the voluntary sector.

CONCLUSIONS

Rehabilitation remains, at its core, a set of relationships between whole individuals (not just skills and needs). A home-based approach is proposed as the norm, not the exception. It is based on a rounded understanding of the patient as a unique person and emphasises the importance of a strong working alliance.

Effects of case-load size on the process of care of patients with severe psychotic illness. Report from the UK700 trial

BACKGROUND

Studies of intensive case management (ICM) for patients with psychotic illnesses have produced conflicting results in terms of outcome. Negative results have sometimes been attributed to a failure to deliver differing patterns of care.

AIMS

To test whether the actual care delivered in a randomised clinical trial of ICM v. standard case management (the UK700 trial) differed significantly.

METHOD

Data on 545 patients' care were collected over 2 years. All patient contacts and all other patient-centred interventions (e.g. telephone calls, carer contacts) of over 15 minutes were prospectively recorded. Rates and distributions of these interventions were compared.

RESULTS

Contact frequency was more than doubled in the ICM group. There were proportionately more failed contacts and carer contacts but there was no difference in the average length of individual contacts or the proportion of contacts in the patients' homes.

CONCLUSIONS

The failure to demonstrate outcome differences in the UK700 study is not due to a failure to vary the treatment process. UK standard care contains many of the characteristics of assertive outreach services and differences in outcome may require that greater attention be paid to delivering evidence-based interventions.

A Delphi approach to describing service models of community mental health practice

OBJECTIVE

The activities of mental health practitioners are poorly understood and described because of a lack of generally accepted and understandable categories. Greater precision is needed for accountability, planning, and evaluation. The objective of this study was to identify a valid and reliable set of categories to describe the clinical work practices of intensive case managers in the United Kingdom.

METHODS

Eight intensive case managers participated in a Delphi process to produce a set of categories that described their clinical work practices. They each completed three questionnaires and participated in a final group discussion.

RESULTS

The initial open questionnaire generated 38 potential categories after exact duplicates were removed. In round 2, the intensive case managers each rated the 38 categories from 1 to 5 (essential to unimportant). A high degree of consensus on the relative importance of the 38 suggested practice categories was rapidly achieved. In round 3, they re-rated the categories in the light of group medians and their own round 2 ratings. In a structured face-to-face discussion group, the intensive case managers then reduced the 38 potential categories to ten comprehensive and mutually exclusive categories that were judged to adequately and accurately reflect work practices. They were housing, finance, daily living skills, criminal justice system, occupation and leisure, engagement, physical health, caregivers and significant others, specific mental health intervention or assessment, and medication.

CONCLUSIONS

Delphi methods were effective and relatively straightforward in producing an agreed-on set of categories with which to record clinical activity and inform care planning.

Are specialist mental health services being targeted on the most needy patients? The effects of setting up special services in general practice

BACKGROUND

Around 25% of patients with psychoses lose contact with specialist psychiatric services, despite the government's policy to focus the efforts of community teams on this group.

AIM

To identify patient and practice factors associated with continuing contact and loss of contact with specialist services.

METHOD

Cross-sectional comparison was made of patients in and out of specialist contact, through detailed interviews with 102 patients among 26 south west London practices. Associations were sought between contact with specialist services and patient factors (illness severity, social functioning, quality of life, needs for care, and satisfaction with general practitioner [GP] services) and practice factors (size, location, fundholding status, training status, and the presence of mental health professionals on site).

RESULTS

Thirty-one (30%) patients were currently out of specialist contact. No significant differences were found between those in and out of contact on any measures of diagnosis or psychiatric history. Those in contact had significantly more symptoms, poorer social functioning, poorer quality of life, and more needs for care. The proportion out of contact was significantly higher in two practices that had employed their own mental health professionals to provides services on site for severe mental illnesses. Two factors remained significant predictors of contact in a logistic regression model: whether or not the patient's practice offered a special service on site, and greater patient needs for care.

CONCLUSIONS

Secondary mental health services are being targeted towards the more needy patients. The provision of special services in practices can shift care further away from secondary care while still meeting patients' needs.

A delphi approach to characterising "relapse" as used in UK clinical practice

BACKGROUND

'Relapse' is a common outcome indicator in intervention studies in schizophrenia. In community studies it is frequently equated with hospitalisation and in psychopharmacological studies with predetermined symptom scores. Its clinical meaning, however, remains undefined.

METHOD

Consensus on the defining features of 'relapse' in schizophrenia used by academic and clinical schizophrenia experts in the UK, was investigated using a four stage Delphi process. A two panel, four stage, Delphi based methodology was used to investigate the implicit meanings of 'relapse' in clinical practice. A multidisciplinary panel of twelve members each listed anonymously ten indicators of relapse. A second panel, of ten experienced psychiatrists, rated the 188 submitted indicators from essential-unimportant (1-5). This panel completed a one day workshop during the remaining Delphi rounds ending with a structured discussion of the results.

RESULTS

Very strong consensus was achieved on the relative importance of potential relapse indicators. There was complete agreement about some aspects of a definition of relapse (such as recurrence of positive symptoms) and a number of the complex issues underlying the concept were clearly articulated.

CONCLUSIONS

This four stage Delphi process achieved consensus on core features of relapse. The elucidation of the "softer" features at the threshold between normal fluctuations in functioning and the start of relapse require continuing investigations.

Molecular and functional characteristics of a protective human monoclonal antibody to serotype 8 Streptococcus pneumoniae capsular polysaccharide

The structural characteristics and biological activity of human antibodies that are reactive with the capsular polysaccharides of most serotypes of Streptococcus pneumoniae, including serotype 8, are unknown. This paper describes the generation, molecular structure, and protective efficacy of a human monoclonal antibody (MAb) reactive with the capsular polysaccharide of serotype 8 Streptococcus pneumoniae. We generated the immunoglobulin M(kappa) [IgM(kappa)] MAb D11 by Epstein-Barr virus transformation of peripheral lymphocytes from a Pneumovax recipient. Nucleic acid sequence analysis revealed that MAb D11 uses V3-15/V(H)3 and A20/V(kappa) gene segments with evidence of somatic mutation. In vitro studies revealed MAb D11-dependent complement deposition on the capsule of serotype 8 organisms via either the classical or the alternative complement pathway. In vivo, MAb D11 prolonged the survival of both normal and C4-deficient mice with lethal serotype 8 S. pneumoniae infection. Our findings demonstrate that a serotype-specific human IgM with certain structural and functional characteristics was protective in mice lacking a functional classical complement pathway and show that alternative complement pathway activation is an important determinant of pneumococcal protection.

Genetic markers, bone mineral density, and serum osteocalcin levels

We evaluated five genetic markers for products that contribute to skeletal mineralization including the Sp1 polymorphism for type I collagen Ai (COLIA1), the vitamin D receptor (VDR) translation initiation site polymorphism, the promoter of the osteocalcin gene containing a C/T polymorphism, the estrogen receptor (ER) gene containing a TA repeat, and the polymorphic (AGC)n site in the androgen receptor. These markers were evaluated for their potential relationship with bone mineral density (BMD), measured by dual-energy X-ray densitometry, or its 3-year change. Additionally, potential associations of these genotypes and with baseline osteocalcin concentration or its 3-year change (assessed using radioimmunoassay) were evaluated. The study was conducted in 261 pre- and perimenopausal women of the Michigan Bone Health Study, a population-based longitudinal study of musculoskeletal characteristics and diseases. The polymorphic (AGC)n site in the androgen receptor showed a strong association with BMD of the femoral neck (FN) and lumbar spine and remained highly significant after adjusting for body mass index (BMI), oophorectomy/hysterectomy, oral contraceptive (OC) use and hormone replacement use (p < 0.001). The TA repeat at the 5' end of the ER gene was associated with total body calcium (p < 0.05) after adjusting for BMI, oophorectomy and hysterectomy, and OC use. The frequency of oophorectomy and hysterectomy within selected genotypes explained much of the statistically significant association of the ER genotypes with BMD of the FN and spine. There was no association of measures of BMD or bone turnover with the Sp1 polymorphism for COLIA1, the VDR translation initiation site polymorphism, or the C/T promoter polymorphism of the osteocalcin gene. These findings suggest that sex hormone genes may be important contributors to the variation in BMD among pre- and perimenopausal women.

Who needs needs?

The idea of assessing needs both in individuals and in populations is popular in health and social care, but has serious conceptual shortcomings. The concept of needs does not distinguish between the identification of a problem and its solution. It inhibits a consideration of the probabilities as to how effective various interventions may be in any given case — nor does it reflect the iterative process that is the reality of most health and social care. It does not specify goals and oversimplifies evaluation of outcome because it does not take into account different degrees of change. In assessing population needs, there is the special risk of equating service use with service need, thereby entrenching the status quo. Instead of assessing needs, it is proposed that we identify problems, specify goals and choose interventions on the basis of probabilities of effectiveness. The outcome of any given intervention can be repeatedly reviewed with respect to its goals, and priorities may be reset accordingly.

Intensive versus standard case management for severe psychotic illness: a randomised trial. UK 700 Group

BACKGROUND

Case management has increasingly been the recommended approach to care for severely mentally ill patients since the number of psychiatric beds has decreased. Despite equivocal results, in the UK and Europe, this approach is becoming accepted policy. We assessed the effect of smaller case loads.

METHODS

We randomly assigned 708 psychotic patients in four centres standard case management (355 patients, case load 30-35 per case manager) or intensive case management (353 patients, case load 10-15 per case manager). We measured clinical symptoms and social functioning at baseline, 1 year, and 2 years. The impact of treatment on hospital use was assessed at 2 years by subgroup analyses for Afro-Caribbean and for severely socially disabled patients. Analysis was by intention to treat.

FINDINGS

There was no significant decline in overall hospital use among intensive-case-management patients (mean 73.5 vs 73.1 days in those who received standard care [SD 0.4, 95% CI -17.4 to 18.1]), nor were there any significant gains in clinical or social functioning. There was no evidence of differential effect in Afro-Caribbean patients or the most socially disabled patients.

INTERPRETATION

In well-coordinated mental-health services, a decline in case load alone does not improve outcome for these patients. Mental-health planners may need to pay more attention to the content of treatment rather than changes in service organisation.

Practice nurses and the care of patients receiving depot neuroleptic treatment: views on training, confidence and use of structured assessment

The movement of care into the community for the mentally ill with severe and enduring problems has important implications for primary care services. This paper reports the findings from an interview with practice nurses working in south-west London, United Kingdom, who had participated in a randomised control trial to investigate the effectiveness of training and structured assessment on clinical and social outcomes of patients receiving maintenance medication of depot antipsychotics. The aim of the interview was to explore current practice, attitudes, confidence and priorities for training in relation to these patients. Thirty-nine nurses were interviewed. The majority of practice nurses received scant referral information and worked without protocols. Even though these nurses had received the training, and as a result of the study had increased awareness of the problems of the severely mentally ill, there was a significant relationship between inadequate knowledge of schizophrenia to carry out the task of medication management and lack of confidence. Although the small size of the sample does not permit generalization, important questions are raised for further practice development and research, including the future training needs of practice nurses and partnership relationships with mental health professionals for supervision and support.

Reducing caregiver burden: a randomized psychoeducational intervention for caregivers of persons with dementia

This 3-year randomized clinical trial tested the effectiveness of an interdisciplinary psychoeducational family group intervention in decreasing the caregivers' perceptions of the frequency and severity of behavioral problems in persons with dementia and their reactions to those problems, and in decreasing caregiver burden and depression. The intervention consisted of seven weekly, 2-hour multimedia training sessions that included education, family support, and skills training for 94 primary caregivers and their families. Repeated measures ANOVA was used to test for significant differences between the intervention and waiting list control groups over a 5-month period. The intervention was successful in reducing caregivers' negative reactions to disruptive behaviors and in reducing caregiver burden over time.

Satisfaction with in-patient psychiatric services. Relationship to patient and treatment factors

BACKGROUND

There is growing concern about patient satisfaction with psychiatric in-patient provision. This paper measures satisfaction in psychiatric in-patients and its relationships with patient characteristics and ward experiences.

AIMS

To: (a) measure overall in-patient satisfaction; (b) examine its relationship to in-patient experiences; and (c) examine its relationship to patient factors.

METHOD

Four hundred and thirty-three patients were interviewed. Satisfaction was assessed by a single quest on, the Client Satisfaction Questionnaire (CSQ) and by a semistructured interview.

RESULTS

Over three-quarters of the patients were satisfied, but two-thirds reported adverse events. Females, younger patients and those detained were more dissatisfied. No significant relationship was found for ethnic group. Results were similar in the mental hospital and district general hospital.

CONCLUSIONS

There remain problems with satisfaction scales. Qualitative approaches to examine patients' experiences in hospital and the causes of dissatisfaction are recommended.

Randomized controlled trial of teaching practice nurses to carry out structured assessments of patients receiving depot antipsychotic injections

BACKGROUND

A third of patients with schizophrenia are out of contact with secondary services. Many of these patients receive maintenance medication as depot antipsychotics from practice nurses, most of whom have negligible training in mental health.

AIM

To examine the impact of a structured assessment on the process of care and clinical status of schizophrenia patients by practice nurses who received a one-day training course.

METHOD

All identified patients were randomly allocated to structured assessments and outcome, measured by the number of assessments and the changes in care recorded in primary care notes. A comprehensive assessment of clinical and social functioning and level of unmet need in intervention and control patients was carried out after one year by an independent researcher.

RESULTS

A high rate of consultation and clinical need in this patient group was demonstrated. Practice nurses were more diligent in carrying out assessments than general practitioners (GPs), but there was no impact on treatment patterns or clinical outcome.

CONCLUSIONS

Structured assessments by practice nurses are feasible with this patient group, but training, targeted at both nurses and GPs, is needed if this intervention is to translate into health gain.

Essential components of schizophrenia care: a Delphi approach

Other than medication and access to in-patient care, there is little published consensus on the essential components of schizophrenia care. This paper reports a Delphi approach to the identification of these components. This approach identifies and measures the degree of consensus, using a structured iterative series of questionnaires by a group of experienced UK and Irish psychiatrists (n = 15) on the essential components. Pharmacotherapy, in-patient care and community mental health team (CMHT) staffing were explicitly excluded from the study. In total, 106 components were identified and their importance was rated twice. There was consensus on 92% of the components and strong consensus on 64%. The Delphi results were refined by the participants to produce 10 essential components of care.
