Systematic evaluations of the relationship between sleep patterns and length of stay in psychiatric intensive care units (PICUs) are lacking. The aims of the present study were to explore if sleep duration or night-to-night variations in sleep duration the first nights predict length of stay in a PICU. Consecutive patients admitted to a PICU were included (N=135) and the nurses registered the time patients were observed sleeping. In the three first nights, the mean sleep duration was 7.5 (±3.2)h. Sleep duration the first night correlated negatively with the length of stay for patients with schizophrenia. The mean difference in sleep duration from night one to night two were 3.3 (±3.0)h and correlated with length of stay for the whole group of patients, but especially for patients with schizophrenia. Patients of all diagnostic groups admitted to a PICU had pronounced intra-individual night-to-night variations in sleep duration. Stabilizing night-to-night variations of sleep duration might be a major goal in treatment., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Background: The aims of the present study were to investigate clinically relevant patient and environment-related predictive factors for threats and violent incidents the first three days in a PICU population based on evaluations done at admittance., Methods: In 2000 and 2001 all 118 consecutive patients were assessed at admittance to a Psychiatric Intensive Care Unit (PICU). Patient-related conditions as actuarial data from present admission, global clinical evaluations by physician at admittance and clinical nurses first day, a single rating with an observer rated scale scoring behaviours that predict short-term violence in psychiatric inpatients (The Brøset Violence Checklist (BVC)) at admittance, and environment-related conditions as use of segregation or not were related to the outcome measure Staff Observation Aggression Scale-Revised (SOAS-R). A multiple logistic regression analysis with SOAS-R as outcome variable was performed., Results: The global clinical evaluations and the BVC were effective and more suitable than actuarial data in predicting short-term aggression. The use of segregation reduced the number of SOAS-R incidents., Conclusions: In a naturalistic group of patients in a PICU segregation of patients lowers the number of aggressive and threatening incidents. Prediction should be based on clinical global judgment, and instruments designed to predict short-term aggression in psychiatric inpatients., Trial Registrations: NCT00184119/NCT00184132.

Psychiatric acute units use different levels of segregation to satisfy needs for containment and decrease in sensory input for behaviourally disturbed patients. Controlled studies evaluating the effects of the procedure are lacking. The aim of the present study was to compare effects in acutely admitted patients with the use of a psychiatric intensive care unit (PICU) and not in a psychiatric acute department. In a naturalistic study, one group of consecutively referred patients had access only to the PICU, the other group to the whole acute unit. Data were obtained for 56 and 62 patients using several scales. There were significant differences in reduction of behaviour associated with imminent, threatening incidents (Broset Violence Checklist), and actual number of such incidents (Staff Observation Aggression Scale-Revised) in favour of the group that was treated in a PICU. The principles of patient segregation in PICUs have favourable effects on behaviours associated with and the actual numbers of violent and threatening incidents. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: The purpose of this study is to compare the development in symptoms, behaviors, function and treatment between patients with or without a substance use (SU) diagnose in a Psychiatric Intensive Care Unit (PICU). Methods: A total of 118 admitted patients were assessed at admittance, day 3 and discharge from the PICU. Symptoms of psychopathology, therapeutic steps taken, violent episodes and length of patient stay were recorded. Results: More males than females received an SU diagnosis. Substance use patients had less psychiatric symptoms at admittance and showed a faster symptom reduction, more favorable and faster improvement of function and a shorter length of stay. Except for symptom reduction and shorter length of stay, these differences were largely due to differences in sex and diagnoses in the two groups. Conclusion: In a naturalistic group of patients in a PICU, SU is associated with favorable outcomes compared to patients not using substances. [Copyright &y& Elsevier]
