Seclusion and restraint usage in seven English psychiatric intensive care units (PICUs)

Treatment of acute psychotic agitation: gaps in the evidence base

Treatment of psychotic agitation is an area that is very poorly evidenced, principally because research evidence from patients with moderate agitation may not generalise to the more severely agitated patients. There is a significant gap between current treatment recommendations and what is seen in clinical practice. There are also big differences in clinical practice between different units treating seemingly similar patient groups. This commentary considers possible reasons for these findings and also discusses non-pharmacological interventions, which probably contribute more to the management of psychotic agitation than does the choice of one antipsychotic drug over another.

Psychopathological Assessment of Risk of Restraint in Acute Psychiatric Patients

The study aims to identify independent predictors of physical restraint in acute psychiatric patients and to determine the predictive power of a risk assessment model centered on psychopathological dimensions. We included 1552 patients admitted to a psychiatric intensive care unit over a 5-year period. Patients were rated on the Brief Psychiatric Rating Scale (BPRS-E) at admission. Principal axis factoring (PAF) with varimax rotation was performed on BPRS-E items to identify psychopathological factors. Multiple logistic regression analysis was performed. PAF pointed six factors: positive symptoms, negative symptoms, resistance, activation, negative affect, and disorganization. Male sex, younger age, proposal for compulsory admission, severity of symptoms, resistance, activation, and disorganization were identified as independent predictors. Negative symptoms and negative affect were instead protective factors. The BPRS-E factors, when added to other sociodemographic and clinical variables, significantly increased the predictive power of the model. Our findings suggest that a systematic evaluation of the psychopathological dimensions can be usefully included in the early risk assessment of restraint.

The prevention of deep venous thrombosis in physically restrained patients with schizophrenia

BACKGROUND

Physical restraint and seclusion are associated with several risks. Antipsychotic drug use increases this risk.

OBJECTIVE

To evaluate whether the risk of thromboembolism in physical restraint and seclusion of patients with psychosis, treated with antipsychotic medication, was considered by taking preventive measures.

METHOD

Anonymous data on all consecutively admitted patients with schizophrenia, treated with antipsychotic medication, between 2002 and 2009, were analysed. Diagnostic information and data about seclusion procedures and medication were collected. Preventive measures of thromboembolism in patients in physical restraint were assessed by reviewing case notes and the medication prescribed at the time of seclusion.

RESULTS

Seclusion of patients with psychosis is common. Out of 679 identified patients, 170 had been secluded (472 events). Physical restraint use was not a rare event (N seclusions with restraint use 296, 62.7%). Pharmacological preventive measures (use of heparine drugs) were taken frequently to prevent deep vein thrombosis (DVT) by physical restraint or isolation. Sixty-five (38.2%) out of 170 secluded patients, including a majority of patients who had been under physical restraint, had been administered anticoagulants at the time of seclusion. No cases of DVT occurred.

CONCLUSIONS

Preventive measures were routinely administered in clinical practice and were effective in the prevention of DVT. For a clinical setting, it is important to establish a clear and detailed management plan on seclusion and fixation taken into account in all possible risks of physical restraint.
