Early intervention for psychosis.

BACKGROUND: Proponents of early intervention have argued that outcome might be improved if more therapeutic efforts were focused on the early stages of schizophrenia or on people with prodromal symptoms. Early intervention in schizophrenia has two elements that are distinct from standard care: early detection and phase-specific treatment. Both elements may be offered as supplements to standard care, or may be provided through a specialised early intervention team. Early intervention is now well established as a therapeutic approach in America, Europe and Australasia, but it is unclear how far early detection, phase-specific treatments, and the use of early intervention teams are underpinned by evidence of effectiveness. OBJECTIVES: To evaluate the effects of: (a) early detection; (b) phase-specific treatments; and (c) specialised early intervention teams in the treatment of people with prodromal symptoms or first episode psychosis. SEARCH STRATEGY: We searched CINAHL (1982-2002), The Cochrane Controlled Trials Register (November 2001), The Cochrane Schizophrenia Group Register (July 2003), EMBASE (1980-2002), MEDLINE (1966-2002), PsycINFO (1967-2002), reference lists and contacted the European First Episode Network (2003). For the 2006 update we searched the Cochrane Schizophrenia Group's register. SELECTION CRITERIA: We included all randomised controlled trials designed to prevent progression to psychosis in people showing prodromal symptoms, or to improve outcome for people with first episode psychosis. Eligible interventions, alone and in combination, included early detection, phase-specific treatments, and care from specialised early intervention teams. We accepted cluster-randomised trials but excluded non-randomised trials. DATA COLLECTION AND ANALYSIS: We reliably selected studies, quality rated them and extracted data. For dichotomous data, we estimated relative risks (RR), with the 95% confidence intervals (CI). Where possible, we calculated the number needed to treat/harm statistic (NNT/H) and used intention-to-treat analysis (ITT). MAIN RESULTS: We included seven studies with a total of 941 participants. Six studies were small with numbers of participants ranging between 56 and 83, and one study randomised 547 people. None of the studies had similar interventions and therefore they were analysed separately. One small Australian trial (n=59) was concerned with a phase-specific intervention (low dose risperidone and cognitive behavioural therapy) for people with prodromal symptoms. This group were significantly less likely to develop psychosis at a six month follow up than people who only received care from a specialised team which did not involve phase-specific treatment (n=59, RR 0.27 CI 0.1 to 0.9, NNT 4 CI 2 to 20). This effect was not significant at 12 month follow up (n=59, 1 RCT, RR 0.54 CI 0.2 to 1.3). A UK-based study (EDIE) randomised 60 people with prodromal symptoms, to cognitive behavioural therapy (CBT) or a monitoring group. Only two outcomes were reported: leaving the study early and transition to psychosis, both sets of data were non-significant. A Chinese trial used a phase-specific intervention (family therapy) plus out patient care trial for people in their first episode of psychosis and found reduced admission rates care compared with those who received only outpatient care (n=83, RR 0.28 CI 0.1 to 0.6, NNT 3 CI 2 to 6). The applicability of this finding was, however, questionable. One Dutch study (n=76) comparing phase-specific intervention (family therapy) plus specialised team with specialised team for people in their first episode of schizophrenia found no difference between intervention and control groups at 12 months for the outcome of relapse (n=76, RR 1.05 CI 0.4 to 3.0). The large Scandinavian study (n=547) allocated people with first episode schizophrenia to integrated treatment (assertive community treatment plus family therapy, social skills training and a modified medication regime) or standard care. Global state outcome GAF significantly favoured integrated treatment (n=419, WMD -3.71 CI -6.7 to -0.7) by one year, but by two years data were non-significant. Rates of attrition were significantly lower (n=547, RR 0.59 CI 0.4 to 0.8, NNT 9 CI 6 to 18) for integrated treatment by one and two year follow-up. PRIME (USA) was the only double blind study and allocated people with prodromal symptoms to olanzapine or placebo. No significant differences were found between olanzapine and placebo in preventing conversion to psychosis by about 12 months (n=60, RR 0.58 CI 0.3 to 1.2). Clinical Global Impression change scores 'severity of illness' were equivocal by 12 months. Scale of Prodromal Symptoms (SOPS) scores were also equivocal and the PANSS, total, positive and negative outcomes were non-significant. There were no significant differences between the olanzapine and placebo group on adverse effects rating scales - SAS, BAS and AIMS scores; Weight gain was significantly higher in the olanzapine group (n=59, WMD 7.63 CI 4.0 to 11.2) by 12 months. Finally one more Australian study included people in their first episode of psychosis who were acutely suicidal and allocated people to phase-specific cognitively orientated therapy or standard care. Outcome data for leaving the study early and suicide were equivocal. AUTHORS' CONCLUSIONS: We identified insufficient trials to draw any definitive conclusions. The substantial international interest in early intervention offers an opportunity to make major positive changes in psychiatric practice, but making the most of this opportunity requires a concerted international programme of research to address key unanswered questions.

A parametric fMRI investigation of context effects in sensorimotor timing and coordination.

Mounting evidence suggests that information derived from environmental and behavioral sources is represented and maintained in the brain in a context-dependent manner. Here we investigate whether activity patterns underlying movements paced according to an internal temporal representation depend on how that representation is acquired during a previous pacing phase. We further investigate the degree to which context dependence is modulated by different time delays between pacing and continuation. BOLD activity was recorded while subjects moved at a rate established during a pacing interval involving either synchronized or syncopated coordination. Either no-delay or a 3, 6 or 9s delay was introduced prior to continuation. Context-dependent regions were identified when differences in neural activity generated during pacing continued to be observed during continuation despite the intervening delay. This pattern was observed in pre-SMA, bilateral lateral premotor cortex, bilateral declive and left inferior semi lunar lobule. These regions were more active when continuation followed from syncopation than from synchronization regardless of the delay length putatively revealing a context-dependent neural representation of the temporal interval. Alternatively, task related regions in which coordination-dependent differences did not persist following the delay, included bilateral putamen and supplementary-motor-area. This network may support the differential timing demands of coordination. A classic prefrontal-parietal-temporal working memory network was active only during continuation possibly providing mnemonic support for actively maintaining temporal information during the variable delay. This work provides support for the hypothesis that some timing information is represented in a task-dependent manner across broad cortical and subcortical networks.

Effect of a nitric oxide releasing derivative of paracetamol in a rat model of endotoxaemia.

BACKGROUND AND PURPOSE: Nitroparacetamol is a nitric oxide-releasing paracetamol with novel anti-inflammatory properties compared to the parent compound. This study has investigated the anti-inflammatory activity of nitroparacetamol in a model of endotoxaemia in rats to probe the mechanisms underlying this effect. EXPERIMENTAL APPROACH: Nitroparacetamol (92 mg kg(-1)), paracetamol (50 mg kg(-1)) or vehicle were administered to male, Wistar rats 15 min prior to or 3 h after lipopolysaccharide (0.5 mg kg(-1), serotype 0127:B8). Mean arterial pressure and heart rate were measured for 5 h and plasma and organs were then obtained to determine organ dysfunction, inducible nitric oxide synthase and cyclooxygenase-2 expression (lung, liver and kidney tissue) and plasma nitrate/nitrite. In separate experiments, nitroparacetamol, paracetamol or vehicle was administered 1 h before acetylcholine (0.1 microg kg(-1)) or sodium nitroprusside (0.25 microg kg(-1)) to determine if nitroparacetamol desensitizes responses to exogenous/endogenous nitric oxide. KEY RESULTS: Nitroparacetamol prevented but did not reverse the lipopolysaccharide-induced hypotension. There was no effect on heart rate or plasma markers of organ dysfunction. Nitroparacetamol prevented the increased plasma nitrate/nitrite and expression of COX-2 and iNOS, whereas paracetamol exerted partial inhibition of COX-2 in lung alone. Nitroparacetamol also reduced responses to acetylcholine and sodium nitroprusside. CONCLUSIONS AND IMPLICATIONS: NO is the active component of nitroparacetamol in this model of endotoxaemia. Pro-inflammatory processes targeted by nitroparacetamol have been shown to include iNOS/COX-2 induction and possibly vascular soluble guanylyl cyclase. Precise mechanisms underlying the NO effect are unclear but inhibition of cytokine formation may be important.

The relationship between specific tissue lesions and pain severity in persons with knee osteoarthritis.

INTRODUCTION: Pain is the most common symptom in knee osteoarthritis (OA), a leading cause of chronic disability, and a major source of the disability attributable to OA in general. Pain severity in knee OA is variable, ranging from barely perceptible to immobilizing. The knee lesions that contribute to pain severity have received little attention. OBJECTIVE: To examine whether worse pathology of specific knee tissues - i.e. cartilage, bone (attrition, cysts, bone marrow lesions, and osteophytes), menisci (tears and subluxation), ligaments, and synovium (synovitis/effusion) - is associated with more severe knee pain. METHODS: One hundred and forty-three individuals were recruited from the community with primary (idiopathic) knee OA, with definite tibiofemoral osteophytes in at least one knee, and at least some difficulty with knee-requiring activity. Knee magnetic resonance (MR) images were acquired using coronal T1-weighted spin-echo (SE), sagittal fat-suppressed dual-echo turbo SE, and axial and coronal fat-suppressed, T1-weighted 3D-fast low angle shot (FLASH) sequences. The whole-organ magnetic resonance imaging (MRI) scoring (WORMS) method was used to score knee tissue status. Since summing tissue scores across the entire joint, including regions free of disease, may dilute the ability to detect a true relationship between that tissue and pain severity, we used the score from the worst compartment (i.e. with the poorest cartilage morphology) as our primary approach. Knee pain severity was measured using knee-specific, 100 mm visual analogue scales. In analyses to evaluate the relationship between knee pain severity and lesion score, median quantile regression was used, adjusting for age and body mass index (BMI), in which a 95% CI excluding 0 is significant. RESULTS: The increase in median pain from median quantile regression, adjusting for age and BMI, was significant for bone attrition (1.91, 95% confidence interval (CI) 0.68, 3.13), bone marrow lesions (3.72, 95% CI 1.76, 5.68), meniscal tears (1.99, 95% CI 0.60, 3.38), and grade 2 or 3 synovitis/effusion vs grade 0 (9.82, 95% CI 0.38, 19.27). The relationship with pain severity was of borderline significance for osteophytes and cartilage morphology and was not significant for bone cysts or meniscal subluxation. Ligament tears were too infrequent for meaningful analysis. When compared to the pain severity in knees with high scores for both bone attrition and bone marrow lesions (median pain severity 40 mm), knees with high attrition alone (30 mm) were not significantly different, but knees with high bone marrow lesion without high attrition scores (15 mm) were significantly less painful. CONCLUSION: In persons with knee OA, knee pain severity was associated with subarticular bone attrition, bone marrow lesions, synovitis/effusion, and meniscal tears. The contribution of bone marrow lesions to pain severity appeared to require the presence of bone attrition.

Distance between the rectal wall and mesorectal fascia measured by MRI: Effect of rectal distension and implications for preoperative prediction of a tumour-free circumferential resection margin.

AIM: To determine the effect of rectal distension, used by some workers to facilitate staging, on mesorectal tissues. SUBJECTS AND METHODS: Ninety-seven consecutive rectal cancer staging MRI examinations were identified of which 76 were analysable: 48 studies were performed using rectal insufflation of 100 ml room air and 28 were performed without distension. Median age was 69 and 72 years, respectively. In each patient a single experienced observer measured the distance from the outer rectal wall to the inner margin of the mesorectal fascia at four locations (12, 3, 6 and 9 o'clock), excluding sites of tumour involvement, from the T1-weighted axial image at the level of the sacro-coccygeal junction. The two groups of measurements were compared using Mann-Whitney test statistic, and frequencies then categorized into <5 mm or > or =5 mm, and compared using Fisher's exact test. RESULTS: The median distance between the rectal wall and mesorectal fascia in the distended group was approximately half that found in the non-distended group, and significantly lower at the 3, 6 and 9 o'clock positions (p<0.001). 68/167 (41%) of measurements were 5mm or less, compared with 19/104 (18%) in the non-distended group (p<0.001). CONCLUSION: Rectal distension before MRI significantly reduces the distance between the rectal wall and mesorectal fascia. Although this is advocated to facilitate visualization of the primary tumour, it potentially affects the accuracy with which a clear circumferential resection margin can be predicted.

Comparison of radiologists' confidence in excluding significant colorectal neoplasia with multidetector-row CT colonography compared with double contrast barium enema.

The aim of this study was to compare the confidence of experienced radiologists in excluding colonic neoplasia with CT colonography (CTC) compared with barium enema. 78 patients (median age 70 years, range 61-87 years, 44 women) underwent same day CTC and barium enema. Two radiologists experienced in reporting barium enema assessed whether the examination had excluded a polyp 6 mm or greater as "yes", "probably" or "no" for each of 6 colonic segments. Two different radiologists experienced in CTC independently performed the same assessment on the CT datasets. Responses were compared using a paired exact test. Formal barium enema and CT reports were compared with any endoscopic examination performed within 1 year. Studies reporting polyps 6 mm+ in patients not subsequently undergoing endoscopy were reviewed by two independent observers. Radiologists stated they had confidently excluded a significant lesion in 314 (71%) and 382 (86%) of 444 segments with barium enema and CTC, respectively (p<0.001). Confidence was significantly higher with CTC in the in the descending and ascending colon (p = 0.02 and p<0.001, respectively), and caecum (p<0.001). 22 patients underwent some form of endoscopy. Of five patients with proven colorectal neoplasia (including two with cancer), CTC and barium enema correctly identified five and three, respectively. In 56 patients not undergoing endoscopy, CTC reported 17 polyps 6 mm+, of which 16 were retrospectively classified as definite or probable. 11 could not be identified on the barium enema, even in retrospect. Confidence in excluding polyps 6 mm or larger is significantly greater with CT colonography particularly in the proximal colon.

External dose estimation for nuclear worker studies.

Epidemiological studies of nuclear workers are an important source of direct information on the health effects of exposure to radiation at low doses and low dose rates. These studies have the important advantage of doses that have been measured objectively through the use of personal dosimeters. However, to make valid comparisons of worker-based estimates with those obtained from data on A-bomb survivors or persons exposed for medical reasons, attention must be given to potential biases and uncertainties in dose estimates. This paper discusses sources of error in worker dose estimates and describes efforts that have been made to quantify these errors. Of particular importance is the extensive study of errors in dosimetry that was conducted as part of a large collaborative study of nuclear workers in 15 countries being coordinated by the International Agency for Research on Cancer. The study, which focused on workers whose dose was primarily from penetrating gamma radiation in the range 100 keV to 3 MeV, included (1) obtaining information on dosimetry practices and radiation characteristics through the use of questionnaires; (2) two detailed studies of exposure conditions, one of nuclear power plants and the other of mixed activity facilities; and (3) a study of dosimeter response characteristics that included laboratory testing of 10 dosimeter designs commonly used historically. Based on these efforts, facility- and calendar year-specific adjustment factors have been developed, which will allow risks to be expressed as functions of organ doses with reasonable confidence.

Risk of cancer after low doses of ionising radiation: retrospective cohort study in 15 countries.

OBJECTIVES: To provide direct estimates of risk of cancer after protracted low doses of ionising radiation and to strengthen the scientific basis of radiation protection standards for environmental, occupational, and medical diagnostic exposures. DESIGN: Multinational retrospective cohort study of cancer mortality. SETTING: Cohorts of workers in the nuclear industry in 15 countries. PARTICIPANTS: 407 391 workers individually monitored for external radiation with a total follow-up of 5.2 million person years. MAIN OUTCOME MEASUREMENTS: Estimates of excess relative risks per sievert (Sv) of radiation dose for mortality from cancers other than leukaemia and from leukaemia excluding chronic lymphocytic leukaemia, the main causes of death considered by radiation protection authorities. RESULTS: The excess relative risk for cancers other than leukaemia was 0.97 per Sv, 95% confidence interval 0.14 to 1.97. Analyses of causes of death related or unrelated to smoking indicate that, although confounding by smoking may be present, it is unlikely to explain all of this increased risk. The excess relative risk for leukaemia excluding chronic lymphocytic leukaemia was 1.93 per Sv (< 0 to 8.47). On the basis of these estimates, 1-2% of deaths from cancer among workers in this cohort may be attributable to radiation. CONCLUSIONS: These estimates, from the largest study of nuclear workers ever conducted, are higher than, but statistically compatible with, the risk estimates used for current radiation protection standards. The results suggest that there is a small excess risk of cancer, even at the low doses and dose rates typically received by nuclear workers in this study.

Early Intervention for psychosis.

BACKGROUND: Proponents of early intervention have argued that outcome might be improved if more therapeutic effort were focused on the early stages of schizophrenia. Early intervention in schizophrenia has two elements that are distinct from standard care: early detection and phase-specific treatment. Both elements may be offered in addition to standard care, or may be provided by a specialised early intervention team. Early intervention is now well established as a therapeutic approach in America, Europe and Australasia, but it is unclear how far early detection, phase-specific treatments, and the use of early intervention teams are underpinned by evidence of effectiveness. OBJECTIVES: This review aims to evaluate the effects of: i. early detection and treatment of people with prodromal symptoms; ii. the use of early intervention teams for people in their first episode of psychosis; and iii. phase-specific treatments for people in their first episode of psychosis. SEARCH STRATEGY: We searched CINAHL (1982-2002), The Cochrane Controlled Trials Register (November 2001), The Cochrane Schizophrenia Group Register (July 2003), EMBASE (1980-2002), MEDLINE (1966-2002), PsycINFO (1967-2002), reference lists and contacted the European First Episode Network (2003). SELECTION CRITERIA: Randomised controlled trials designed to prevent progression to psychosis in people showing prodromal symptoms, or improve outcome for people with first episode psychosis. Eligible interventions, alone and in combination, included early detection, phase-specific treatments, and care from specialised early intervention teams. Non-randomised trials would only have been included if they had been studies of the effects of early detection strategies in reducing the duration of untreated psychosis (since this issue cannot be addressed by simple randomisation). DATA COLLECTION AND ANALYSIS: Data were extracted independently by two reviewers and cross-checked. Relative risks (RR) and 95% confidence intervals (CI) were calculated for dichotomous data. Weighted mean differences (WMD) were calculated for continuous data. MAIN RESULTS: In theory, seventeen different comparisons are possible, but the review only identified three studies that met inclusion criteria. One small trial (n=59) was concerned with a phase-specific intervention (low dose risperidone and cognitive behavioural therapy) for people with prodromal symptoms. This group were significantly less likely to develop psychosis at 6 month follow up than people who only received care from a specialised team which did not involve phase-specific treatment (n=59, 1 RCT, RR 0.27 CI 0.08 to 0.89, NNT 4 CI 2 to 20). This effect was not significant at 12 month follow up (n=59, 1 RCT, RR 0.54 CI 0.23 to 1.30). Another trial found that people in their first episode receiving a phase-specific intervention (family therapy) plus out patient care did have reduced admission rates care compared with those who received only outpatient care (n=83, 1 RCT, RR 0.28 CI 0.13 to 0.62, NNT 3 CI 2 to 6). The applicability of this finding was, however, questionable.Finally, one last study (n=76), comparing phase-specific intervention (family therapy) plus specialised team with specialised team for people in their first episode of schizophrenia found no difference between intervention and control groups at 12 months for the outcome of relapse but confidence intervals were wide (n=76, RR 1.06 CI 0.31 to 3.65). REVIEWERS' CONCLUSIONS: We identified insufficient trials to draw any definitive conclusions, although five ongoing trials should report shortly. The substantial international interest in early intervention offers an opportunity to make major positive changes in psychiatric practice, but this opportunity may be missed without a concerted international programme of research to address key unanswered questions.

Assessing the needs of people with learning disabilities and mental illness: development of the Learning Disability version of the Cardinal Needs Schedule.

BACKGROUND: People with learning disability (LD) experience a range of mental health problems. They are a complex population, whose needs are not well understood. This study focuses on the development of a systematic process of needs assessment for this population. METHODS: The Cardinal Needs Schedule used in general psychiatry was adapted for people with learning disabilities (LD). The Learning Disability version of the Cardinal Needs Schedule (LDCNS) was tested on a sample of 35 people with LD and mental illness for its inter-rater reliability. RESULTS: The inter-rater reliability (Kappa) was calculated for 22 areas of functioning assessed by the LDCNS. Overall, there was very good agreement in seven areas, moderate agreement in six areas, fair agreement in three areas and poor agreement in one area. In four areas of functioning, Kappa could not be calculated. More needs were found in the social domain than in the clinical domain. CONCLUSION: A systematic needs assessment schedule (LDCNS) was developed for people with LD and mental illness. The inter-rater reliability is generally acceptable, but requires further examination.

Organisational change theory and the use of indicators in general practice.

General practices are making greater use of indicators to help shape and develop organisational arrangements supporting the delivery of health care. Debate continues concerning what exactly such indicators should measure and how they should be used to achieve improvement. Organisational theories can provide an analytical backdrop to inform the design of indicators, critique their construction, and evaluate their use. Systems theory, organisational development, social worlds theory, and complexity theory each has a practical contribution to make to our understanding of how indicators work in prompting quality improvements and why they sometimes don't. This paper argues that systems theory exerts the most influence over the use of indicators. It concludes that a strategic framework for quality improvement should take account of all four theories, recognising the multiple realities that any one approach will fail to reflect.

Assessing organisational development in primary medical care using a group based assessment: the Maturity Matrix.

OBJECTIVE: To design and develop an instrument to assess the degree of organisational development achieved in primary medical care organisations. DESIGN: An iterative development, feasibility and validation study of an organisational assessment instrument. SETTING: Primary medical care organisations. PARTICIPANTS: Primary care teams and external facilitators. MAIN OUTCOME MEASURES: Responses to an evaluation questionnaire, qualitative process feedback, hypothesis testing, and quantitative psychometric analysis (face and construct validity) of the results of a Maturity Matrix assessment in 55 primary medical care organisations. RESULTS: Evaluations by 390 participants revealed high face validity with respect to its usefulness as a review and planning tool at the practice level. Feedback from facilitators suggests that it helped practices to prioritise their organisational development. With respect to construct validity, there was some support for the hypothesis that training and non-training status affected the degree and pattern of organisational development. The size of the organisation did not have a significant impact on the degree of organisational development. CONCLUSION: This practice based facilitated group evaluation method was found to be both useful and enjoyable by the participating organisations. Psychometric validation revealed high face validity. Further developments are in place to ensure acceptability for summative work (benchmarking) and formative feedback processes (quality improvement).

Re-thinking accountability: trust versus confidence in medical practice.

In seeking to prevent a reoccurrence of scandals such as that involving cardiac surgery in Bristol, the UK government has adopted a model of regulation that uses rules and surveillance as a way of both improving the quality of care delivered and increasing confidence in healthcare institutions. However, this approach may actually act to reduce confidence and trust while also reducing the moral motivation of practitioners. Accountability in health care is discussed, and it is suggested that openness about the difficult dilemmas that arise when practitioners have a duty to be accountable to more than one audience may be an alternative means of restoring trust. A greater emphasis on the sharing of information between individual health professionals and their patients would increase trust and would allow patients to hold their doctors to account for the quality of care they receive. Concentrating more on developing trust by the sharing of information and less on the futile search for complete confidence in systems and rules may improve the quality of care delivered while also nurturing the moral motivation of professionals upon which the delivery of high quality health care depends.

Systematic assessments of need and care planning in severe mental illness: cluster randomised controlled trial.

BACKGROUND: Surveys have shown high levels of unmet need in representative samples of people with severe mental illness. Introducing standardised needs assessment into the care planning process might reduce these needs and improve outcome. AIMS: To determine whether feedback from a standardised assessment of need enhances the effectiveness of care planning and whether exposing care coordinators to feedback on some patients improves their care of other patients. METHOD: A single-blind, cluster randomised trial involving a within-cluster individually randomised arm: patients' needs were evaluated using the Cardinal Needs Schedule and the findings were fed back to their care coordinators under the care programme approach. A total of 304 patients were recruited from 72 care coordinators and 242 patients (79.6%) were reassessed at 12 months. RESULTS: The only significant effect of the intervention was on patient satisfaction. Patients cluster-randomised to receive feedback were more satisfied than controls, but patients individually randomised to receive feedback were not. CONCLUSIONS: Standardised needs assessment did not substantially enhance care planning in this trial. However, giving care coordinators some experience of feedback from a standardised assessment of need could improve satisfaction.

Day hospital versus admission for acute psychiatric disorders.

BACKGROUND: Inpatient treatment is an expensive way of caring for people with acute psychiatric disorders. It has been proposed that many of those currently treated as inpatients could be cared for in acute psychiatric day hospitals. OBJECTIVES: To assess the effects of day hospital versus inpatient care for people with acute psychiatric disorders. SEARCH STRATEGY: We searched the Cochrane Controlled Trials Register (Cochrane Library, issue 4, 2000), MEDLINE (January 1966 to December 2000), EMBASE (1980 to December 2000), CINAHL (1982 to December 2000), PsycLIT (1966 to December 2000), and the reference lists of articles. We approached trialists to identify unpublished studies. SELECTION CRITERIA: Randomised controlled trials of day hospital versus inpatient care, for people with acute psychiatric disorders. Studies were ineligible if a majority of participants were under 18 or over 65, or had a primary diagnosis of substance abuse or organic brain disorder. DATA COLLECTION AND ANALYSIS: Data were extracted independently by two reviewers and cross-checked. Relative risks and 95% confidence intervals (CI) were calculated for dichotomous data. Weighted or standardised means were calculated for continuous data. Day hospital trials tend to present similar outcomes in slightly different formats, making it difficult to synthesise data. Individual patient data were therefore sought so that outcomes could be reanalysed in a common format. MAIN RESULTS: Nine trials (involving 1568 people) met the inclusion criteria. Individual patient data were obtained for four trials (involving 594 people). Combined data suggested that, at the most pessimistic estimate, day hospital treatment was feasible for 23% (n=2268, CI 21 to 25) of those currently admitted to inpatient care. Individual patient data from three trials showed no difference in number of days in hospital between day hospital patients and controls (n=465, 3 RCTs, WMD -0.38 days/month CI -1.32 to 0.55). However, compared to controls, people randomised to day hospital care spent significantly more days in day hospital care (n=265, 3 RCTs, WMD 2.34 days/month CI 1.97 to 2.70) and significantly fewer days in inpatient care (n=265, 3 RCTs, WMD -2.75 days/month CI -3.63 to -1.87). There was no significant difference in readmission rates between day hospital patients and controls (n=667, 5 RCTs, RR 0.91 CI 0.72 to 1.15). For patients judged suitable for day hospital care, individual patient data from three trials showed a significant time-treatment interaction, indicating a more rapid improvement in mental state (n=407, Chi-squared 9.66, p=0.002), but not social functioning (n=295, Chi-squared 0.006, p=0.941) amongst patients treated in the day hospital. Four of five trials found that day hospital care was cheaper than inpatient care (with cost reductions ranging from 20.9 to 36.9%). REVIEWER'S CONCLUSIONS: Caring for people in acute day hospitals can achieve substantial reductions in the numbers of people needing inpatient care, whilst improving patient outcome.
