Risk assessment is a core skill in psychiatry. Risk prediction for suicide in schizophrenia is known to be complex. We undertook a systematic review of all original studies concerning suicide in schizophrenia published since 2004. We found 51 data-containing studies (from 1281 studies screened) that met our inclusion criteria, and ranked these by standardized quality criteria. Estimates of rates of suicide and risk factors associated with later suicide were identified, and the risk factors were grouped according to type and strength of association with suicide. Consensus on the lifetime risk of suicide was a rate of approximately 5%. Risk factors with a strong association with later suicide included being young, male, and with a high level of education. Illness-related risk factors were important predictors, with number of prior suicide attempts, depressive symptoms, active hallucinations and delusions, and the presence of insight all having a strong evidential basis. A family history of suicide, and comorbid substance misuse were also positively associated with later suicide. The only consistent protective factor for suicide was delivery of and adherence to effective treatment. Prevention of suicide in schizophrenia will rely on identifying those individuals at risk, and treating comorbid depression and substance misuse, as well as providing best available treatment for psychotic symptoms.

In Finland, only a minority of patients adhere to their initial antipsychotic during the first 60 days after discharge from their first hospitalization for schizophrenia. Use of depot antipsychotics was associated with a significantly lower risk of rehospitalization than use of oral formulations of the same compounds. Among oral antipsychotics, clozapine and olanzapine were associated with more favorable outcomes. Use of any antipsychotic was associated with lower mortality.

We aimed to construct and assess a new self rating scale to detect the side effects of second generation antipsychotics. This scale was designed to allow a timely, sensitive and reliable method of gathering information on the number and severity of side effects an individual suffers from. The Glasgow Antipscyhotic Side-effect Scale (GASS) was developed after literature review, discussion with members of the mental health team and with service user feedback. Fifty indivudals taking second generation antipsychotics completed the GASS along with the Liverpool Univeristy Neuroleptic Side Effect Rating Scale, and one week later completed the GASS for a second time. Fifty comparison subjects also completed the GASS. The GASS was shown to have good discrimatory power and construct validity, along with good re-test reliablity, and is put forward as a short, helpful and valid clinical tool.

Antipsychotic adverse effects are diverse and frequently experienced, but are not often systematically assessed. There is a need for further scientific study concerning the management of these side effects.

Long-acting injections continue to have an image problem, arguably perpetuated by manufacturers of oral second-generation antipsychotic drugs, and exacerbated by the predominant use of these medications as a ;last resort' often for the most stigmatized individuals. The introduction of better-tolerated LAIs and better education of both staff and patients may encourage individuals to re-examine their attitudes.

The results are variable and inconclusive. Some evidence suggests that FGA-LAIs may improve outcome compared with oral antipsychotics. Methodological issues may partly explain the variable results. Selective recruitment in RCTs and lack of randomisation in observational studies are biases against LAIs, whereas regression to the mean in mirror-image studies favours LAIs. In terms of future research, a long-term pragmatic RCT of an FGA-LAI against an oral antipsychotic, in patients with problematic adherence, would be of value.
