Psychoeducation and motivational interviewing to reduce relapses and increase patients' involvement in antipsychotic treatment: interventional study.

AIMS AND METHOD: To assess whether the combination of motivational interviewing and psychoeducation affects relapse rate and stimulates involvement of people with psychosis in their treatment. We conducted an interventional study including patients with schizophrenia or schizoaffective disorder treated with oral antipsychotics, without previous experience of long-acting injectable antipsychotics (LAIs). They were randomised to either psychoeducation with motivational interviewing or a control group. Hospital admissions 18 months before and after the intervention, and switches to LAIs 18 months after the intervention, were recorded. RESULTS: The two groups each comprised 101 participants. Fourteen from the intervention group and seven from the control group switched to LAIs. Five in the intervention group instigated the switch themselves, compared with zero controls (P = 0.06). Fourteen in the intervention group were readmitted to hospital during follow-up, compared with 23 in the control group (P = 0.14). CLINICAL IMPLICATIONS: Psychoeducation with motivational interviewing may increase patients' involvement in their treatment and reduce the relapse frequency.

Perceptions and knowledge of antipsychotics among mental health professionals and patients.

Aims and method To assess the patients' most influential concerns regarding long-acting injectable antipsychotics (LAIs) and mental health professionals' preconceptions about these concerns. For both groups, to assess the level of knowledge about LAIs. This cross-sectional study used semi-structured interviews of patients with schizophrenia or schizoaffective disorder (n = 164), nurses (n = 43) and physicians (n = 20). Results The mental health professionals overestimated many of the patients' fears of LAIs, and the expressed fears exceeded the actual experiences of patients already on LAIs. Acceptance to switch to LAIs was associated with shorter time from diagnosis. Nurses and patients disclosed limited knowledge of antipsychotics. Clinical implications Physicians and nurses should aim to identify the individual patient's concerns about LAIs in the discussion about choice of antipsychotic treatment early in the course of illness.

Diabetes and glucose disturbances in patients with psychosis in Sweden.

OBJECTIVE: The objectives of this study were to (1) analyze the prevalence of diabetes, prediabetes, and antidiabetic medication in patients with psychosis compared with control subjects and (2) determine what factors in patients with psychosis were associated with antidiabetic medication. METHOD: We studied 977 patients with psychosis recruited from outpatient clinics in Stockholm County, Sweden, and they were compared with 3908 non-psychotic control subjects for fasting plasma glucose levels; prevalence of diabetes, prediabetes, antidiabetic treatment, and tobacco use; and blood pressure, weight, height, and waist circumference. Group differences were evaluated with analysis of variance and χ(2) test, and factors associated with antidiabetic treatment were evaluated with logistic regression. RESULTS: Diabetes was observed in 94 (10%) patients with psychosis, 2.7 times the prevalence observed in control subjects. Among patients with psychosis, 87 (10%) had prediabetes (fasting glucose, 6.1-6.9 mmol/L) compared with 149 (3.8%) control subjects. Most patients with psychosis (77%) who had prediabetes fulfilled criteria for metabolic syndrome. In patients with psychosis, both lipid-lowering medication and fasting glucose were significantly associated with antidiabetic treatment. There was no significant relation between antidiabetic treatment and lifestyle factors such as smoking or degree of psychiatric illness. CONCLUSIONS: The high prevalence of impaired fasting glucose and metabolic syndrome in patients with psychosis warrants further clinical research in preventing or delaying the onset of diabetes in these patients by pharmacotherapy and/or lifestyle intervention.

The impact on schizophrenia-related hospital utilization and costs of switching to long-acting risperidone injections in Sweden.

AIM: To estimate changes in resource usage, hospitalization rates, and costs in actual practice in Sweden for schizophrenia patients after switching to long-acting injectable risperidone (Risperdal Consta). METHODS: A retrospective chart review within-subject mirror-image study using actual practice chart review data was used to compare annual hospital bed-days and annual hospital episodes for adults with schizophrenia or schizoaffective disorder before and after switching to Risperdal Consta in the period 1 January 2003 to 30 June 2005. Secondary endpoints included mean length of hospital stay per episode, the cost of hospitalization, and the cost of antipsychotic treatment. The base case analytical approach allocated all hospital episodes overlapping the switch date entirely to pre-switch treatment. In order to investigate the impact of inpatient care ongoing at the time of the switch, the change in bed-days per year was also estimated using an alternative analytical approach inspired by economic modelling. RESULTS: One-hundred sixty-four patients were enrolled at nine geographically diverse sites. The switch to Risperdal Consta was associated with a significant reduction in mean annual days in hospital from 39 to 21 days per year (45%), which was linked to a significant reduction in the number of hospitalizations from 0.86 to 0.63 per year (27%). The alternative "modelling-inspired" estimate of the reduction in mean annual days in hospital was also 27%. CONCLUSION: A naturalistic mirror-image study found that switching to long-acting injectable risperidone led to sizeable reductions in inpatient resource use. These results coincide with the findings of other international studies.
