Violence perpetrated by psychiatric inpatients is associated with modifiable factors. Current structured approaches to assess inpatient violence risk lack predictive validity and linkage to interventions.

Adult psychiatric inpatients on forensic and general wards in three psychiatric hospitals were recruited and followed up prospectively for 6 months. Information on modifiable (dynamic) risk factors were collected every 1–4 weeks, and baseline background factors. Data were transferred to a web-based monitoring system (FOxWeb) to calculate a total dynamic risk score. Outcomes were extracted from an incident-reporting system recording aggression and interpersonal violence. The association between total dynamic score and violent incidents was assessed by multilevel logistic regression and compared with dynamic score excluded.

We recruited 89 patients and conducted 624 separate assessments (median 5/patient). Mean age was 39 (s.d. 12.5) years with 20% (n = 18) female. Common diagnoses were schizophrenia-spectrum disorders (70%, n = 62) and personality disorders (20%, n = 18). There were 93 violent incidents. Factors contributing to violence risk were a total dynamic score of ⩾1 (OR 3.39, 95% CI 1.25–9.20), 10-year increase in age (OR 0.67, 0.47–0.96), and female sex (OR 2.78, 1.04–7.40). Non-significant associations with schizophrenia-spectrum disorder were found (OR 0.50, 0.20–1.21). In a fixed-effect model using all covariates, AUC was 0.77 (0.72–0.82) and 0.75 (0.70–0.80) when the dynamic score was excluded.

In predicting violence risk in individuals with psychiatric disorders, modifiable factors added little incremental value beyond static ones in a psychiatric inpatient setting. Future work should make a clear distinction between risk factors that assist in prediction and those linked to needs.

Violent behaviour by forensic psychiatric inpatients is common. We aimed to systematically review the performance of structured risk assessment tools for violence in these settings.

The nine most commonly used violence risk assessment instruments used in psychiatric hospitals were examined. A systematic search of five databases (CINAHL, Embase, Global Health, PsycINFO and PubMed) was conducted to identify studies examining the predictive accuracy of these tools in forensic psychiatric inpatient settings. Risk assessment instruments were separated into those designed for imminent (within 24 hours) violence prediction and those designed for longer-term prediction. A range of accuracy measures and descriptive variables were extracted. A quality assessment was performed for each eligible study using the QUADAS-2. Summary performance measures (sensitivity, specificity, positive and negative predictive values, diagnostic odds ratio, and area under the curve value) and HSROC curves were produced. In addition, meta-regression analyses investigated study and sample effects on tool performance.

Fifty-two eligible publications were identified, of which 43 provided information on tool accuracy in the form of AUC statistics. These provided data on 78 individual samples, with information on 6,840 patients. Of these, 35 samples (3,306 patients from 19 publications) provided data on all performance measures. The median AUC value for the wider group of 78 samples was higher for imminent tools (AUC 0.83; IQR: 0.71–0.85) compared with longer-term tools (AUC 0.68; IQR: 0.62-0.75). Other performance measures indicated variable accuracy for imminent and longer-term tools. Meta-regression indicated that no study or sample-related characteristics were associated with between-study differences in AUCs.

The performance of current tools in predicting risk of violence beyond the first few days is variable, and the selection of which tool to use in clinical practice should consider accuracy estimates. For more imminent violence, however, there is evidence in support of brief scalable assessment tools.

Individual placement and support (IPS) has been repeatedly demonstrated to be the most effective form of mental health vocational rehabilitation. Its no-discharge policy plus fixed caseloads, however, makes it expensive to provide.

To test whether introducing a time limit for IPS would significantly alter its clinical effectiveness and consequently its potential cost-effectiveness.

Referrals to an IPS service were randomly allocated to either standard IPS or to time-limited IPS (IPS-LITE). IPS-LITE participants were referred back to their mental health teams if still unemployed at 9 months or after 4 months employment support. The primary outcome at 18 months was working for 1 day. Secondary outcomes comprised other vocational measures plus clinical and social functioning. The differential rates of discharge were used to calculate a notional increased capacity and to model potential rates and costs of employment.

A total of 123 patients were randomised and data were collected on 120 patients at 18 months. The two groups (IPS-LITE = 62 and IPS = 61) were well matched at baseline. Rates of employment were equal at 18 months (IPS-LITE = 24 (41%) and IPS = 27 (46%)) at which time 57 (97%) had been discharged from the IPS-LITE service and 16 (28%) from IPS. Only 11 patients (4 IPS-LITE and 7 IPS) obtained their first employment after 9 months. There were no significant differences in any other outcomes. IPS-LITE discharges generated a potential capacity increase of 46.5% compared to 12.7% in IPS which would translate into 35.8 returns to work in IPS-LITE compared to 30.6 in IPS over an 18-month period if the rates remained constant.

IPS-LITE is equally effective to IPS and only minimal extra employment is gained by persisting beyond 9 months. If released capacity is utilised with similar outcomes, IPS-LITE results in an increase by 17% in numbers gaining employment within 18 months compared to IPS and will increase with prolonged follow-up. IPS-LITE may be more cost-effective and should be actively considered as an alternative within public services.

Coercion has usually been equated with legal detention. Non-statutory pressures to adhere to treatment, ‘leverage’, have been identified as widespread in US public mental healthcare. It is not clear if this is so outside the USA.

To measure rates of different non-statutory pressures in distinct clinical populations in England, to test their associations with patient characteristics and compare them with US rates.

Data were collected by a structured interview conducted by independent researchers supplemented by data extraction from case notes.

We recruited a sample of 417 participants from four differing clinical populations. Lifetime experience of leverage was reported in 35% of the sample, 63% in substance misusers, 33% and 30% in the psychosis samples and 15% in the non-psychosis sample. Leverage was associated with repeated hospitalisations, substance misuse diagnosis and lower insight as measured by the Insight and Treatment Attitudes Questionnaire. Housing leverage was the most frequent form (24%). Levels were markedly lower than those reported in the USA.

Non-statutory pressure to adhere to treatment (leverage) is common in English mental healthcare but has received little clinical or research attention. Urgent attention is needed to understand its variation and place in community practice.
