Abstract
OBJECTIVE Home-based care for severe mental illness has been the focus of intense research over the last 30 years and has produced mixed results. Replications of Assertive Community Treatment (ACT) in Europe have consistently failed to find these differences and various explanations have been advanced for this. METHOD Studies were compared in context of health care, and then identifying and rating the components of the differing teams rather than simply their designation. Cluster analysis was used for the identification of common service characteristics and regression analysis to test for correlation with reduction in hospitalization. RESULTS The nature of the control service may significantly explain the international variation in results. Six regularly occurring features of experimental services were identified from the examination of the components - smaller case loads, regularly visiting at home, a high percentage of contacts at home, responsibility for health and social care, multidisciplinary teams and a psychiatrist integrated in the team. Two of these, regularly visiting at home and responsibility for health and social care, are significantly associated with a reduction in hospitalization. CONCLUSIONS It is premature to define an optimal configuration for home based care services. The need for introducing differing components of such care will depend on what is currently available locally. Where regular home visiting to psychotic patients plus a broad service model incorporating health and social care objectives are provided, major reductions in in-patient care are not currently to be anticipated by service re-configurations.

Abstract
OBJECTIVE Recent work has focussed on schizophrenia as a 'deficit' state but little attention has been paid to defining illness plasticity in terms of symptomatic remission. METHOD A qualitative review of a recently proposed concept of remission [N.C. Andreasen, W.T. Carpenter Jr, J.M. Kane, R.A. Lasser, S.R. Marder, D.R. Weinberger (2005) Am J Psychiatry 162: 441] is presented. RESULTS The proposed definition of remission is conceptually viable, and can be easily implemented in clinical trials and clinical practice. Its increasing acceptance may reset expectations of treatment to a higher level, improve documentation of clinical status and facilitate dialogue on treatment expectations. The availability of validated outcome measures based on remission will enhance the conduct and reporting of clinical investigations, and could facilitate the design and interpretation of new studies on cognition and functional outcomes. While useful as a concept, it is important to consider that remission is distinct from recovery. CONCLUSION The introduction of standardized remission criteria may offer significant opportunities for clinical practice, health services research and clinical trials.

Abstract
Schizophrenia is a chronic disabling disease which in the majority of cases requires long-term treatment with antipsychotic medication. Before the development of atypical antipsychotics, treatment choice was restricted to conventional (or typical) antipsychotics, which are known to cause a range of side effects including extrapyramidal symptoms. Although atypical agents provide a favourable alternative (advocated by the National Institute of Clinical Excellence in the UK), they are associated with side effects. These differ between agents, but can include weight gain, sedation and hyperprolactinaemia. Aripiprazole is a newly available atypical antipsychotic for the treatment of schizophrenia. With the apparent imitations of currently available medications, aripiprazole provides clinicians with another treatment option. The purpose of these guidelines is to outline the consensus reached by the Schizophrenia Innovation Working Group on best practice in prescribing and appropriate use of aripiprazole in the UK.

Abstract
OBJECTIVE To examine the dental health of community dwelling people with schizophrenia and to compare results with those in the general population. METHOD Dental health of 428 people with schizophrenia in six different areas of the UK was assessed by a self-report questionnaire. RESULTS Compared with the general population, significantly more of the younger patients were edentate (3-39% vs. 1-20%) and fewer had more than 20 teeth (70% vs. 83%). None of four dental health targets had been achieved in the patient population. More patients had last visited the dentist because of trouble with their teeth; fewer had visited for a check-up. Fewer patients cleaned their teeth daily; this group had more negative symptoms. CONCLUSION The dental health of people with schizophrenia is poor. Community mental health teams should encourage them to attend their community dentist regularly.

Abstract
Streptococcus pneumoniae is an important cause of community-acquired pneumonia, meningitis, and bacteremia. The problem of pneumococcal disease is exacerbated by increasing drug resistance. Furthermore, patients with impaired immunity are at high risk for invasive pneumococcal infections. Thus, there is an urgent need for new approaches to antimicrobial therapy. Antibody therapies take advantage of the specificity and high affinity of the antigen-antibody interaction to deliver antibacterial compounds to a site of infection in the form of naked or conjugated antibodies. We have recently established that radioimmunotherapy (RIT) can be used to treat experimental fungal infections in mice. In the present study, we investigated the feasibility of applying a RIT approach to the treatment of S. pneumoniae infection by evaluating the susceptibility of S. pneumoniae to radiolabeled antibody in vitro and in an animal infection model. For the specific antibody carrier, we used human monoclonal antibody D11, which binds to pneumococcal capsular polysaccharide 8. We have selected the alpha particle emitter (213)Bi as the radionuclide for conjugation to the antibody. Incubation of serotype 8 S. pneumoniae with (213)Bi-D11 resulted in dose-dependent killing of bacteria. RIT of S. pneumoniae infection in C57BL/6 mice showed that 60% more mice survived in the (213)Bi-D11-treated group (80 micro Ci) than in the untreated group (P < 0.01). The treatment did not cause hematological toxicity, as demonstrated by platelet counts. This feasibility study establishes that RIT can be applied to the treatment of bacterial infections.

Abstract
OBJECTIVE There are four services providing mental health care to the people of Kumasi, Ghana. This study aimed to identify previous help sought by patients presenting to the services for an initial assessment. METHOD New patients presenting to each of the four services were asked about distance travelled, previous help sought and time since symptoms of illness started. Staff also recorded basic demographic details and clinical diagnoses. RESULTS Of the 322 patients presenting to the four sites,only 6% had seen a traditional healer whereas 14% had seen a pastor before presentation. There was a greater delay in presenting to that service if the patient had seen a traditional healer or pastor. Many patients had previously used one of the other mental health units in Kumasi. CONCLUSION It is possible that fewer patients with mental health problems present to traditional healers in modern, urban Africa compared to rural areas. More patients consult with pastors than traditional healers and liaison with these groups may improve mental health care. It is important to maintain liaison between the four services as patients presenting to one clinic may have presented previously to another local clinic.

Abstract
OBJECTIVE Several factors influence whether individuals with affective disorders seek help. The Zurich cohort study provides an opportunity to explore patient-based factors without confounding with problems of access. This study aims to identify features which predict help-seeking behaviour in symptomatic individuals and to explore failure of help seeking in those who did not. METHOD Characteristics of currently symptomatic 40-year-old individuals in a stratified epidemiological sample were tested against help-seeking behaviour using bivariate statistics and logistic regression. Individual predictors were identified and interaction effects tested. RESULTS Thirty-one per cent of the 364 subjects sought help in the preceding year. Past treatment and living alone were significantly associated with treatment. Total number of symptoms and several individual symptoms correlated with treatment in the bivariate analyses but regression analysis identified "unfounded self-reproach" and "hopelessness" interacting with social support to predict the best treatment. CONCLUSION Social support is strongly protective against needing help in the presence of distressing affective symptoms unless these symptoms become elaborated into conclusions about their meaning and prognostic significance.

Abstract
Thirty-four mixed breed horses from two separate farms showed signs of abdominal discomfort, pyrexia and dehydration after being exposed to a new batch of 14% complete horse feed. A new batch of cattle feed from the same manufacturer resulted in dairy cows showing depression, a drop in milk production and diarrhoea. Examination of both diets revealed the presence of white kidney beans (Phaseolus vulgaris). Inclusion of raw beans of this genus in animal feeds is to be avoided.

Abstract
OBJECTIVE To examine the association between co-morbid personality disorder (PD) and suicidal behaviour over a 2-year period in a sample of patients with psychosis. METHOD A total of 670 patients with established psychotic illness were interviewed using a battery of instruments including a screen for co-morbid PD. The prevalence of attempted and completed suicide was measured over the next 2 years using multiple data sources. Logistic regression was used to examine whether those with co-morbid PD were at greater risk of suicidal behaviour compared with others. RESULTS One hundred and eighty six patients (28%) were rated as having a co-morbid PD. After adjusting for all covariates, patients with co-morbid PD were significantly more likely to attempt or complete suicide over the 2-year period (adjusted odds ratio: 1.87; 95% CI: 1.02-3.42). CONCLUSION Co-morbid PD is independently associated with an increased risk of suicidal behaviour in psychosis. Early assessment of personality status should be part of the routine assessment of all psychiatric patients.

Abstract
OBJECTIVE To compare patterns of clinical activity amongst existing staff in two inner-city community mental health teams before and after their enhancement with extra resources using a new activity schedule containing 11 comprehensive and mutually exclusive practice categories. METHOD Patterns of clinical activity amongst existing members of two inner-London community mental health teams were compared before and after the addition of extra resources. RESULTS The amount of time spent in face-to-face contact with patients and carers showed no meaningful change following team enhancement. Patterns of clinical activity amongst team members remained relatively static. CONCLUSION Adding resources to community mental teams without considering how to target the time released amongst existing staff may reduce their capacity to work more innovatively.

Abstract
BACKGROUND It is perceived that North American home treatment studies reveal greater success in reducing days in hospital than do European studies. There are difficulties in extrapolating findings internationally. AIMS We aimed to determine whether North American studies find greater reductions in days in hospital and whether experimental service patients in North American studies spend less time in hospital. METHOD The results of a systematic review were analysed with respect to study location. Service components ascertained through follow-up were utilised to interpret the meta-analyses conducted. RESULTS Most of the 91 studies found were from the USA and UK. North American studies found a difference of one hospital day (per patient per month) more than European studies but there was no difference in experimental data between the two locations. CONCLUSIONS North American studies demonstrate greater differences in days in hospital but patients in their experimental services seem to spend no fewer days in hospital, implying a disparity in control services.

Abstract
OBJECTIVE Alcohol misuse in psychotic patients is common and leads to poor treatment outcome. This study examines the relationship between alcohol consumption and cost of care in patients with a severe psychotic illness. METHOD Patient care was evaluated over 2 years for 708 patients. Patient reported alcohol consumption was evaluated at initial interview. The outcome measure was cost of care over 2 years. RESULTS There was no difference in mean cost of care between non-drinkers, moderate and heavy drinkers. Increased alcohol consumption (measured as a continuous variable, adjusted for baseline characteristics) was associated with lower cost of care. CONCLUSION Heavier alcohol consumers did not incur more treatment costs and may, indeed, cost less than other patients. This may reflect higher levels of drinking being associated with better overall functioning, poorer engagement with services or exclusion from services.

Abstract
BACKGROUND Concerns have been raised about the scope and generalizability of much community mental health research. In particular, both experimental and control services are poorly characterized. METHODS To review the effectiveness of 'home treatment' for mental health problems in terms of hospitalization, we conducted a systematic review, using Cochrane methodology but with a wider remit. Non-randomized studies were included in response to concerns about RCTs' generalizability. All authors were followed up for data on service components. 'Home treatment' was defined broadly for the purposes of the literature search, but included studies were then assessed against service components specifically focused on delivering treatment at home. The study tested components and other features for associations with days in hospital, as well as conducting a conventional meta-analysis of data on days in hospital. RESULTS We found 91 studies, 18 comparing home to in-patient treatment. Sixty per cent of authors responded to follow-up. The vast majority of the services studied had a 'home treatment function' and regularly visited patients at home. The heterogeneity of control services made meta-analysis problematical as did the limited availability of data. There was some evidence that 'regular' home visiting and combined responsibility for health and social care were associated with reduced hospitalization. The inclusion of non-randomized studies rarely affected the findings. CONCLUSIONS Evidence concerning the effectiveness of home treatment remains inconclusive. A centrally coordinated research strategy is recommended, with attention to study design. Experimental and control service components should be prospectively recorded and reported to enable meaningful analysis.

Abstract
As more and more novel antipsychotic agents are introduced, the need for practical guidelines on switching these medications is becoming increasingly important. Indications for a switch include situations where the patient or his family/caregiver requests a change in medication, where the patient cannot tolerate current treatment, where they have comorbid physical or psychiatric conditions or where they have achieved only a partial remission, are refractory to treatment or have relapsed. Cross-tapering is generally the most acceptable method of switching, although abrupt withdrawal may be necessary in some cases, such as when a patient develops a severe or acute reaction to their current treatment. Possible problems of switching include the risk of discontinuation reactions and the re-emergence of psychotic symptoms. The pharmacological profile of amisulpride means it has a relatively low potential for interactions with other drugs and may be started while discontinuing the previous antipsychotic. It should be started at the target dose for the patient's current symptoms. A retrospective questionnaire among 60 patients switching to amisulpride treatment was undertaken to identify the characteristics of patients switching antipsychotics and their reasons. Patients were switched from a variety of antipsychotic medications, both traditional (42% of patients) and atypical (58%). Most patients (87%) had at least two reasons for changing medication, with lack of efficacy, adverse events and treatment optimisation before reintegration being the most common. Contrary to recommendations, 89% of patients were switched abruptly between medications. A total of 62% of patients received amisulpride doses in the range 400-800 mg/day and most (72%) required no dose adjustment. The great majority of patients (87%) switched to amisulpride without problems.

Abstract
The purpose of this exploratory study was to examine the perceptions of 115 female spouse caregivers of early to moderate stage dementia patients. Based on patients' cognitive status, cross-sectional comparisons of two groups of caregiving wives were conducted. No group differences were found in measures of caregiver burden, depression, or personal gain. However, wives of patients with greater cognitive impairment experienced lower levels of mastery and more relational deprivation when compared to wives of patients with higher mental status. Supportive approaches might be directed toward helping early dementia caregivers restructure their understanding of, and participation in, their marital relationships in anticipation of changes ahead. Interventions aimed at enhancing a caregiver's sense of personal mastery may help reduce the negative effects of dementia on caregivers' well-being.

Abstract
Five studies have been conducted with the atypical anti-psychotic amisulpride (100-1200 mg/day) involving 1358 patients with acute exacerbations of schizophrenia; four studies were short-term (4-8 weeks), double-blind studies and one was a 12-month, open, randomized comparison. Amisulpride improved positive symptoms consistently, and changes were more pronounced than with haloperidol, flupenthixol and risperidone; amisulpride showed a more rapid onset of action compared to haloperidol, and improvement in negative symptoms was more effective than with any comparator. An optimum response was obtained with amisulpride doses 400-800 mg/day. The long-term study confirmed the usefulness of amisulpride for maintenance treatment in schizophrenia, with a clear advantage over haloperidol, leading to better functioning and quality of life. Amisulpride caused fewer neurological side-effects than conventional anti-psychotics and less weight gain than risperidone, both of which are crucial factors for long-term compliance.

Abstract
OBJECTIVE This review investigates the effectiveness of 'home treatment' for mental health problems in terms of hospitalisation and cost-effectiveness. For the purposes of this review, 'home treatment' is defined as a service that enables the patient to be treated outside hospital as far as possible and remain in their usual place of residence. METHODS - SYSTEMATIC LITERATURE SEARCH: 'Home treatment' excluded studies focused on day, residential and foster care. The review was based on Cochrane methodology, but non-randomised studies were included if they compared two services; these were only analysed if they provided evidence of the groups' baseline clinical comparability. METHODS - REVIEW OF ECONOMIC EVALUATIONS: Economic evaluations among the studies found were reviewed against established criteria. METHODS - IDENTIFICATION OF SERVICE COMPONENTS: A three-round Delphi exercise ascertained the degree of consensus among expert psychiatrists concerning the important components of community-based services that enable them to treat patients outside hospital. The identified components were used to construct the follow-up questionnaire. METHODS - FOLLOW-UP OF AUTHORS: As a supplement to the information available in the papers, authors of all the studies were followed up for data on service components, sustainability of programmes and service utilisation. METHODS - DATA ANALYSIS: The outcome measure was mean days in hospital per patient per month over the follow-up period. (1) Comparative analysis - compared experimental to control services. It analysed all studies with available data, divided into 'inpatient-control' and 'community-control' studies, and tested for associations between service components and difference in hospital days. (2) Experimental services analysis - analysed only experimental service data and tested for associations between service components and hospital days. RESULTS - SYSTEMATIC LITERATURE SEARCH: A total of 91 studies were found, conducted over a 30-year period. The majority (87) focused on people with psychotic disorders. RESULTS - REVIEW OF ECONOMIC EVALUATIONS: Only 22 studies included economic evaluations. They provided little conclusive evidence about cost-effectiveness because of problems with the heterogeneity of services, sample size, outcome measures and quality of analysis. RESULTS - DELPHI EXERCISE: In all, 16 items were rated as 'essential', falling into six categories: home environment; skill-mix; psychiatrist involvement; service management; caseload size; and health/social care integration. There was consensus that caseloads under 25 and flexible working hours over 7 days were important, but little support for caseloads under 15 or for 24-hour services, and consensus that home visiting was essential, but not on teams being 'explicitly dedicated' to home treatment. RESULTS - RESPONSE TO FOLLOW-UP: A total of 60% of authors responded, supplying data on service components and hospital days in most cases. Other service utilisation data were far less readily available. RESULTS - SERVICE CHARACTERISATION AND CLASSIFICATION: The services were homogeneous in terms of 'home treatment function' but fairly heterogeneous in terms of other components. There was some evidence for a group of services that were multidisciplinary, had psychiatrists as integrated team members, had smaller caseloads, visited patients at home regularly and took responsibility for both health and social care. This was not a cohesive group, however. RESULTS - SUSTAINABILITY OF SERVICES: The sustainability of home treatment services was modest: less than half the services whose authors responded were still identifiable. Services were more likely to be operational if the study had found them to reduce hospitalisation significantly. RESULTS - META-ANALYSIS: Meta-analysis with heterogeneous studies is problematic. The evidence base for the effectiveness of services identifiable as 'home treatment' was not strong. Within the 'inpatient-control' study group, the mean reduction in hospitalisation was 5 days per patient per month (for 1-year studies only). No statistical significance could be measured for this result. For 'community-control' studies, the reduction in hospitalisation was negligible. Moreover, the heterogeneity of control services, the wide range of outcome measures and the limited availability of data might have confounded the analysis. Regularly visiting at home and dual responsibility for health and social care were associated with reduced hospitalisation. Evidence for other components was inconclusive. Few conclusions could be drawn from the analysis of service utilisation data. RESULTS - LOCATION: Studies were predominately from the USA and UK, more of them being from the USA. North American studies found a reduction in hospitalisation of 1 day per patient per month more than European studies. North American and European services differed on some service components, but this was unlikely to account for this finding, particularly as no difference was found in their experimental service results. CONCLUSIONS - STATE OF RESEARCH: There is a clear need for further studies, particularly in the UK. The benefit of home treatment over admission in terms of days in hospital was clear, but over other community-based alternatives was inconclusive. CONCLUSIONS - NON-RANDOMISED STUDIES: Difficulties in systematically searching for non-randomised studies may have contributed to the smaller number of such studies found (35, compared with 56 randomised controlled trials). This imbalance was compounded by a relatively poor response rate from non-randomised controlled trial authors. Including them in the analysis had little effect. CONCLUSIONS - LIMITATIONS OF THIS REVIEW: A broad area was reviewed in order to avoid the problem of analysing by service label. While reviews of narrower areas may risk implying a homogeneity of the services that is unwarranted, the current strategy has the drawback that the studies cover a range of heterogeneous services. The poor definition of control services, however, is ubiquitous in this field, however reviewed areas are defined. Inclusion of mean data for which no standard deviations were available was problematic in that it prevented measuring the significance of the main findings. The lack of availability of this data, however, is an important finding, demonstrating the difficulty in seeking certainty in this area. Only days in hospital and cost-effectiveness were analysed here. The range and lack of uniformity of measures used in this field made meta-analysis of other outcomes impossible. It should be noted, however, that the findings pertain to these aspects alone. The Delphi exercise reported here was limited in being conducted only with psychiatrists, rather than a multidisciplinary panel. Its findings were used as a framework for the follow-up and analysis. Their possible bias should be borne in mind when considering them as findings in themselves. CONCLUSIONS - IMPLICATIONS FOR CLINICIANS: The evidence base for home treatment compared with other community-based services is not strong, although it does show that home treatment reduces days spent in hospital compared with inpatient treatment. There is evidence that visiting patients at home regularly and taking responsibility for both health and social care each reduce days in hospital. CONCLUSIONS - IMPLICATIONS FOR CONSUMERS: Services that visit patients at home regularly and those that take responsibility for both health and social care are likely to reduce time spent in hospital. Psychiatrists surveyed in this review also considered support for carers to be essential. The evidence from this review, however, was that few services currently have protocols for meeting carers' needs. CONCLUSIONS - RECOMMENDATIONS FOR RESEARCH AND COMMISSIONERS: A centrally coordinated research strategy, with attention to study design, is recommended. Studies should include economic evaluations that report health and social service utilisation. Service components should be collected and reported for both experimental and control services. Studies should be designed with adequate power and longer durations of follow-up and use comparable outcome measures to facilitate meta-analysis. Research protocols should be adhered to throughout the studies. It may be advisable that independent researchers conduct studies in future. It is no longer recommended that home treatment be tested against inpatient care, or that small, localised studies replicate existing, more highly powered studies.

Abstract
BACKGROUND Research shows considerable variability in the effect on relatives of patients' mental illness but the determinants of relatives' experience remain unclear. We investigated the influence of demographic, social and clinical characteristics on relatives' experience when conceptualised using a stress-appraisal-coping paradigm. METHODS Our sample was drawn from relatives of patients recruited to the UK700 case management study (n = 154). Demographic, social and clinical data were collected from patients, and relatives completed the Experience of Caregiving Inventory and the General Health Questionnaire. We predicted that patients' symptomatology in particular would influence relatives' experience, and that relatives who appraised caregiving more negatively and less positively would experience greater psychological distress. RESULTS Linear regression analyses revealed that relatives' appraisal was not predicted by patients' symptomatology. Instead, relatives appraised caregiving more negatively if the patient was unemployed or younger, and less positively if the patient had been ill for longer or had poorer social functioning. Little of the variance in appraisal was explained by these variables, however. Consistent with the stress-coping model, relatives' negative appraisal was a strong predictor of psychological distress and accounted for a substantial proportion of its variance. Positive appraisal did not predict psychological distress, however. None of the demographic, social or clinical characteristics tested had any significant effect on relatives' psychological distress once appraisal was adjusted for. There was an unexpected positive correlation between the two appraisal scales, with relatives who appraised caregiving more negatively also appraising it more positively. CONCLUSIONS Our results support a stress-coping model of caregiving but further research is required to determine more influential predictors of relatives' appraisal. Our findings indicate that interventions aimed at patients' social functioning and relatives' negative appraisal of caregiving may assist in reducing relatives' psychological distress.

Abstract
The aim of this study was to explore nurses' experiences of stress within the context of intensive care. The theoretical perspective for the study builds on a cognitive-phenomenological-transactional theory of stress and coping and the theory of cognitive dissonance. Respondents were 36 registered nurses recruited from 10 intensive care units (general, neonatal and thoracic units). Their experience as nurses ranged from one to 32 years. These intensive care units had similar structural characteristics, namely a high working pace, advanced technology, constrained finances, frequent reorganizations, a shortage of registered nurses and all were filled to overcapacity. Data were collected in open-ended interviews that were audio-taped and transcribed. A content analysis identified four contradictory themes: (1) controlled by the work situation--needing to be in control; (2) constrained by prioritization--wanting to do more; (3) lacking the authority to act--knowing that something should be done; and (4) professional distance--interpersonal involvement. These four themes were synthesized at a higher level of abstraction into a main theme: stress induced by dissonant imperatives, which conceptualizes nursing stress in the intensive care unit. In conclusion, dissonant imperatives might lead to stress in intensive care nursing.

Abstract
OBJECTIVE To compare the efficacy and safety of 250 microg and 500 microg of recombinant hCG with 10,000 U USP of urinary hCG in assisted reproduction technology. DESIGN Open, comparative, randomized, prospective clinical study. SETTING Twenty tertiary care U.S. infertility centers. PATIENT(S) Two hundred ninety-seven ovulatory infertile women undergoing a single cycle of assisted reproduction technology. INTERVENTION(S) Patients were randomized 1:1:1 to 250 microg of recombinant hCG SC, 500 microg of recombinant hCG SC, or 10,000 U USP urinary hCG IM after completing gonadotropin stimulation. MAIN OUTCOME MEASURE(S) Number of oocytes retrieved per patient receiving hCG. Also, measures of oocyte maturity, embryo development, and luteal function, as well as pregnancy and pregnancy outcome. Adverse safety events, laboratory changes, local tolerance, and immunogenicity were also assessed. RESULT(S) Mean numbers of oocytes retrieved per treatment group were equivalent, 13.6, 14.6, and 13.7 with 250 microg of recombinant hCG, 500 microg of recombinant hCG, and urinary hCG, respectively. The numbers of 2PN fertilized oocytes on day 1 after oocyte retrieval, and 2PN or cleaved embryos on the day of embryo transfer, were significantly higher with 500 microg of recombinant hCG than with the lower dose. However, the incidence of adverse events also tended to be higher with this dose. CONCLUSION(S) Recombinant hCG is effective and well tolerated in the induction of final follicular maturation and luteinization in women undergoing assisted reproduction technology. Recombinant hCG (250 microg) SC is equivalent to 10,000 U USP of urinary hCG in this indication.

Abstract
OBJECTIVE To explore the stability of conclusions from mental health services research across differing care systems. Contradictory results in different countries for similar studies of programmes for patients with schizophrenia have usually been attributed to poor replication. This paper explores whether these differing results can illuminate aspects of schizophrenia by examining the interaction of the disorder with the care context as an alternative explanation. METHOD The findings of a large UK random controlled trial of intensive case management with such patients is compared to previous UK and US studies. RESULTS Reduction of case-load size of psychotic patients did not significantly reduce their need for hospitalization in the context of locally available co-ordinated care. CONCLUSION There is more to be gained in understanding complex disorders such as schizophrenia by interpreting the impact of context on treatment study outcomes than by simply dismissing contradictory findings as failures of implementation of either research or clinical practice.

Abstract
OBJECTIVE Case management studies from Europe and the United States continue to yield conflicting results. At a symposium at the World Psychiatric Conference in Hamburg in 1999, researchers from four European countries explored the possible reasons for differences in outcome. They also examined reasons for the differing foci of case management studies across the different cultures. The authors summarize the symposium's findings. METHODS Individual case presentations were given of studies and services from the United Kingdom (three studies), Sweden (two studies), Germany, and Italy (one each). Outcomes, methodologies, and national service context were examined. RESULTS AND CONCLUSIONS A significant influence of national culture is evident both in the acceptability of case management and in approaches to researching it. Case management is perceived as an "Anglophone import" in Italy but is now national policy for persons with severe mental illness in the other three countries. Studies from the United Kingdom emphasized methodological rigor, with little attention to treatment content, whereas those from Sweden accepted a less disruptive research approach but with a more prescriptive stipulation of treatment content. Studies from Italy and Germany emphasized the importance of differing descriptive methodologies. Marked differences in the range of social care provision were noted across Europe. Overall, European researchers are less concerned than U.S. researchers with studying the impact of case management on hospital use.
