RESUMEN

OBJECTIVE: Historically, patients with multiple acts of aggression, or chronic aggressors, have been studied as one large group. It was our objective to subdivide this group into those patients who engage in physical aggression consistently over multiple years and see if common characteristics of chronic aggressors could classify patients into an aggressive or nonaggressive group. METHOD: Within a forensic hospital system, patients who had committed 5 acts of physical aggression, per year, for 3 years (2010 and 2015) were reviewed. Data was collected on clinical and demographic characteristics that have shown to be associated with chronically aggressive patients and compared to nonaggressive matched controls. Data collection and analysis were completed to determine if the variables could classify patients into an aggressive or nonaggressive group. RESULTS: Analysis showed that 2 variables, the presence of a cognitive disorder and a history of suicidal behaviors were significant in the univariate and multivariate analyses. The 2 variables were able to correctly classify 76.7% of the cases. CONCLUSION: A cognitive disorder, a history of suicidal behavior, and increased age were factors associated with this subgroup of aggressive patients. Clinicians may want to explore treatment programs aimed at these clinical factors including cognitive rehabilitation and social cognition treatments, which have been shown to reduce aggression in cognitively impaired populations.

RESUMEN

OBJECTIVE: We investigated clinical and demographic variables to better understand their relationship to hospital length of stay for patients involuntarily committed to California state psychiatric hospitals under the state's incompetent to stand trial (IST) statutes. Additionally, we determined the most important variables in the model that influenced patient length of stay. METHODS: We retrospectively studied all patients admitted as IST to California state psychiatric hospitals during the period January 1, 2010 through June 30, 2018 (N = 20 041). Primary diagnosis, total number of violent acts while hospitalized, age at admission, treating hospital, level of functioning at admission, ethnicity, sex, and having had a previous state hospital admission were evaluated using a parametric survival model. RESULTS: The analysis showed that the most important variables related to length of stay were (1) diagnosis, (2) number of violent acts while hospitalized, and (3) age of admission. Specifically, longer length of stay was associated with (1) having a diagnosis of schizophrenia or neurocognitive disorder, (2) one or more violent acts, and (3) older age at admission. The other variables studied were also statistically significant, but not as influential in the model. CONCLUSIONS: We found significant relations between length of stay and the variables studied, with the most important variables being (1) diagnosis, (2) number of physically violent acts, and (3) age at admission. These findings emphasize the need for treatments to target cognitive issues in the seriously mentally ill as well as treatment of violence and early identification of violence risk factors.

RESUMEN

Sexually violent predator (SVP) laws allow the postprison civil commitment of sex offenders to a secure psychiatric hospital because of mental abnormality and posing a serious risk to public safety. Research on predictors of future institutional violence in this population is lacking because adequately sized samples are difficult to obtain. In the current study, we examined psychological predictors of future institutional violence in a sample of 171 psychiatrically hospitalized males detained or civilly committed under an SVP laws. Using the Minnesota Multiphasic-Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008/2011), we found that scales assessing thought dysfunction, emotional dysregulation, and externalizing behaviors were associated with future physical violence at the hospital. Relative risk ratio analyses indicated that SVPs producing elevations on these scales were at 1.5-2.5 times greater risk of future physical violence than those without elevations. Overall, the results suggest the Minnesota Multiphasic-Personality Inventory-2-Restructured Form is associated with future institutional violence among SVPs. Implications and limitations of these findings are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

RESUMEN

UNLABELLED: Introduction We examined physical violence in a large, multihospital state psychiatric system during 2011-2013, and associated demographic and clinical characteristics of violent patients to better understand issues of patient and staff safety. METHOD: Acts of physical violence committed by patients against other patients (n=10,958) or against staff (n=8429) during 2011-2013 were collected and analyzed for all hospitalized patients during the same time period to derive prevalence rates and associated odds ratios. RESULTS: Overall, 31.4% of patients committed at least 1 violent assault during their hospitalization. Differential risk factor patterns were noted across patient and staff assault. Younger age was associated with a higher prevalence of both patient and staff assault, as was nonforensic legal status. Females had a higher prevalence of staff assault than patient assault. Ethnic groups varied on rates of patient assault, but had no significant differences for staff assault. Schizoaffective disorder was associated with higher prevalence and odds of patient (OR 1.244, 95% CI 1.131 to 1.370) and staff (OR 1.346, 95% CI 1.202 to 1.507) assault when compared to patients diagnosed with schizophrenia. Most personality disorder diagnoses also had a higher prevalence and odds of physical violence. One percent of patients accounted for 28.7% of all assaults. Additionally, violent patients had a significantly longer length of hospitalization. Discussion Implications of these findings to enhance patient safety and inform future violence reduction efforts, including the need for new treatments in conjunction with the use of violence risk assessments, are discussed.

RESUMEN

Here we provide comprehensive guidelines for the assessment and treatment of violence and aggression of various etiologies, including psychotic aggression and impulsive aggression due to schizophrenia, mood disorders, ADHD, or trauma, and predatory aggression due to psychopathy and other personality disorders. These guidelines have been developed from a collection of prescribing recommendations, clinical trial results, and years of clinical experience in treating patients who are persistently violent or aggressive in the California Department of State Hospital System. Many of the recommendations provided in these guidelines employ off-label prescribing practices; thus, sound clinical judgment based on individual patient needs and according to institution formularies must be considered when applying these guidelines in clinical practice.
