Disposition of presumed coronary patients from an emergency room. A follow-up study

All patients with presumed coronary problems seen at the Chaim Sheba Medical Center during a one-year period were followed up. The fate of those who were not hospitalized and the factors contributing to the two types of erroneous decisions, ie, refusing hospitalization to those needing it and unnecessary hospitalization of others, were evaluated. Approximately 50% of the patients were not admitted. Myocardial infarctions were later diagnosed in 6% of these patients. Another 8% were eventually categorized as other cardiac emergencies. Ten percent of all patients subsequently diagnosed as having myocardial infarctions were not admitted. On the other hand, 56% of the patients whose cases were later not considered to have been emergencies were hospitalized unnecessarily. Previous hospitalization for cardiac disease played a major role in making an error of both types. Other factors influencing the physician's decision regarding the patients' disposition included their age, sex, ethnic origin, and the findings from the emergency room electrocardiogram.     

Clinical Decision Making About Psychopathy and Violence Risk Assessment in Public Sector Mental Health Settings.

Although there has been extensive research on psychopathy, it is unknown how, or whether, clinicians in public sector mental health settings consider the Psychopathy Checklist (PCL) for assessing violence risk. Mental health clinicians (N = 135) from 4 facilities were interviewed by using multiple methods for collecting data on decision making. Participants considered clinical information most often when assessing violence risk, indicating that these data were most readily available. Clinicians perceived formal testing results (e.g., PCL) to be least available and considered testing least often, especially if clinicians had less clinical experience. Participants did not explicitly report using the PCL but did implicitly rely on psychopathy factors when assessing violence risk. Clinicians in crisis settings reported less availability of historical data typically needed for the PCL. The data point to specific ways to improve the clinical practice of violence risk assessment in public mental health settings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Workplace violence: Prevention, response, and recovery.

Describes a model of collaboration between business leaders and mental health clinicians in developing programs and strategies to prevent violence, handle acute crises, and cope with recovery and rebuilding in the aftermath of a workplace violence incident. Sections address the following: (1) demographics, costs, and risk factors and warning signs of workplace violence; (2) workplace violence prevention policies, including hiring, discipline, and termination practices; (3) responses to emergencies, such as potentially dangerous situations, violent episodes, and guns or weapons in the workplace; and (4) strategies for recovery following workplace violence that involve mental health and law enforcement mobilization, dealing with the media, assisting employees and families, legal issues, identification and treatment of posttraumatic stress disorder (PTSD), and follow-up procedures.

The psychological assessment of risk for crime and violence.

This article provides an overview of the current practices and challenges in psychological risk assessment for crime and violence. Risk assessments have improved considerably during the past 20 years. The dismal predictive accuracy of unstructured professional opinion has largely been replaced by more accurate, structured risk assessment methods. Consensus has not been achieved, however, on the constructs assessed by the various risk tools, nor the best method of combining factors into an overall evaluation of risk. Advancing risk assessment for crime and violence requires psychometrically sound evaluations of psychologically meaningful causal risk factors described using nonarbitrary metrics.

The validity and reliability of the Violence Risk Scale: A treatment-friendly violence risk assessment tool.

The development of risk assessment tools that use dynamic variables to predict recidivism and to inform and facilitate violence reduction interventions is the next major challenge in the field of risk assessment and management. This study is the first in a 2-step process to validate the Violence Risk Scale (VRS), a risk assessment tool that integrates violence assessment, prediction, and treatment. Ratings of the 6 static and 20 dynamic VRS variables assess the client's level of risk. Ratings of the dynamic variables identify treatment targets linked to violence, and ratings of the stages of change of the treatment targets assess the client's treatment readiness and change. The VRS scores of 918 male offenders showed good interrater reliability and internal consistency and could predict violent and nonviolent recidivism over both short- and longer term (4.4-year) follow-up. The probability of violent and nonviolent recidivism varied linearly with VRS scores. Dynamic and static variables performed equally well. The results support the contention that the VRS can be used to assess violent risk and to guide violence reduction treatment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychopathy and violence: The importance of factor level interactions.

The power of scales based on the Psychopathy Checklist (PCL; R. D. Hare, 1980) for prediction of violent behavior is well established. Although evidence suggests that this relationship is chiefly due to the impulsive and antisocial lifestyle component (Factor 2), the predictive power of psychopathy for violence may also reflect the multiplicative effects of this component with interpersonal and unemotional traits (Factor 1). The determination of the extent to which psychopathy subcomponents interact to predict violence has theoretical and practical implications for PCL-assessed psychopathy. However, the relationship between violence and the interactive effects of psychopathy subcomponents remains largely undetermined. The authors used prospective and cross-sectional designs to examine the independent and interactive effects of the factors of PCL-assessed psychopathy in 2 samples: (a) 199 county jail inmates and (b) 863 civil psychiatric patients. The Factor 1 × Factor 2 interaction predicted violence in both samples, such that the predictive power of Factor 2 was attenuated at lower levels of Factor 1.

The efficacy of violence prediction: A meta-analytic comparison of nine risk assessment tools.

Actuarial risk assessment tools are used extensively to predict future violence, but previous studies comparing their predictive accuracies have produced inconsistent findings as a result of various methodological issues. We conducted meta-analyses of the effect sizes of 9 commonly used risk assessment tools and their subscales to compare their predictive efficacies for violence. The effect sizes were extracted from 28 original reports published between 1999 and 2008, which assessed the predictive accuracy of more than one tool. We used a within-subject design to improve statistical power and multilevel regression models to disentangle random effects of variation between studies and tools and to adjust for study features. All 9 tools and their subscales predicted violence at about the same moderate level of predictive efficacy with the exception of Psychopathy Checklist—Revised (PCL-R) Factor 1, which predicted violence only at chance level among men. Approximately 25% of the total variance was due to differences between tools, whereas approximately 85% of heterogeneity between studies was explained by methodological features (age, length of follow-up, different types of violent outcome, sex, and sex-related interactions). Sex-differentiated efficacy was found for a small number of the tools. If the intention is only to predict future violence, then the 9 tools are essentially interchangeable; the selection of which tool to use in practice should depend on what other functions the tool can perform rather than on its efficacy in predicting violence. The moderate level of predictive accuracy of these tools suggests that they should not be used solely for some criminal justice decision making that requires a very high level of accuracy such as preventive detention.

Scientizing and routinizing the assessment of suicidality in outpatient practice.

Suicidal patients are difficult and challenging clinical problems. Conceptual tools aid the clinician in organizing and evaluating the clinical situation. The authors provide a framework for suicide risk assessment that emphasizes 2 domains–history of past attempt and the nature of current suicidal symptoms–that have emerged in suicide research as crucial variables. These domains, when combined with other categories of risk factors, produce a categorization of risk for the individual patient, leading, in turn, to relatively routinized clinical decision making and activity.

A review of recent research addressing the utility of the Rorschach.

To address the utility of the Rorschach, the author synthesized a large sample (N?=?138) of empirical, quantitative research published in the past 20 years. Longitudinal and behavioral criteria and ecological incremental validity beyond self-report and interview were emphasized because of their relationship with test applications. Methodological issues (temporal consistency, diversity, clinician judgment), applications (treatment outcome, schizophrenia, thought disorder, depression and suicide risk), and selected Rorschach variables are addressed. The evidence reveals that many Rorschach variables are efficient tools for clinical, forensic, and educational applications. The test is particularly useful in (a) individualizing case conceptualizations and interventions and (b) predicting and evaluating outcomes. These conclusions are consistent with using the Rorschach as a behavioral problem-solving test that illuminates the interaction among psychological, biological, and environmental factors.

Correlates of vascular access and nonvascular access-related hospitalizations in hemodialysis patients

Four hundred and thirty randomly selected hemodialysis patients, aged 20 years and over, were studied to identify risk factors for vascular access and nonvascular access-related hospitalizations in the immediately preceding 1 year. Risk estimates for hospitalization were assessed using a multinominal logistic analysis model. We measured functional status, utilizing a 14-point Karnofsky scale, and in a separate analysis of covariance, in which Karnofsky score was the outcome, we examined the relationships of age, gender, ethnicity, renal diagnosis, and hospitalization. Individual comparisons were adjusted for multiple comparison bias by Tukey's Honest Difference method. There were a total of 508 hospitalizations of which 322 (63%) lasted > or = 1 week. Two hundred and sixty (60%) patients were hospitalized at least once; 105 (24.4%) for access problems only, 115 (27%) for a nonaccess problem only, and 40 for access and nonaccess-related problems. Access-related problems, accounted for 48% of all hospitalizations. The risk of hemodialysis vascular access morbidity was increased in women (p < 0.028) and white (p < 0.048) hemodialysis patients. Neither diabetic nor elderly hemodialysis patients were at greater risk for access hospitalization than their respective counterparts, though a greater proportion of the access hospitalizations in the elderly (> or = 64 years) lasted > or = 1 week (p < 0.0006). More access-related hospitalizations in blacks (64.5%), lasted for > or = 1 week than in whites (40.6%) (p < 0.001). Hispanics (p < 0.043), whites (p < 0.002), and the older patients (p < 0.054) were at greater risk for nonaccess hospitalization than blacks and younger patients, respectively. Even after adjusting for age, race, and diabetes, each decrease of one unit in the modified Karnofsky score was associated with a 3-4% increased risk for all types of hospitalization (p < 0.001)--poor functional status is associated with increased risk for all hospitalizations. We conclude that the risk for hemodialysis vascular access morbidity is increased in women and white hemodialysis patients. Poor functional status is associated with increased risk for all hospitalizations.     

The relationship between confidence and accuracy in clinical assessment of psychiatric patients' potential for violence

The authors studied the relationship between confidence and accuracy in clinical assessments of psychiatric patients' short-term risk of violence. At the time of entry to the hospital, physicians (N = 78) estimated the probability that each of 317 patients would physically attack other people during the first week of psychiatric hospitalization. The clinicians also indicated the degree of confidence they had in their estimates of violence potential. Nurses rated the occurrence of inpatient physical assaults with the Overt Aggression Scale. The results showed that when clinicians had a high degree of confidence, their evaluations of risk of violence were strongly associated with whether or not patients became violent. At moderate levels of confidence, clinicians' risk estimates had a lower, but still substantial relationship with the later occurrence of violence. However, when clinicians had low confidence, their assessments of potential for violence had little relationship to whether or not the patients became violent. The findings suggest that the level of confidence that clinicians have in their evaluations is an important moderator of the predictive validity of their assessments of patients' potential for violence.     

Assessing risk for violence among psychiatric patients: The HCR-20 violence risk assessment scheme and the Psychopathy Checklist: Screening Version.

This study examined the predictive validity of the HCR–20 (Historical, Clinical, and Risk Management) violence risk assessment scheme and the Psychopathy Checklist: Screening Version (PCL:SV). Files of 193 civilly committed patients were coded. Patients were followed up in the community for an average of 626 days. Receiver operating characteristic analyses with the HCR–20 yielded strong associations with violence (areas under curve [AUCs?=?.76–.80). Persons scoring above the HCR–20 median were 6 to 13 times more likely to be violent than those scoring below the median. PCL:SV AUCs were more variable (.68–.79). Regression analyses revealed that the HCR–20 added incremental validity to the PCL:SV and that only HCR–20 subscales predicted violence. Implications for risk assessment research, and the clinical assessment and management of violence, are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychiatric symptoms and community violence among high-risk patients: A test of the relationship at the weekly level.

Given the availability of violence risk assessment tools, clinicians are now better able to identify high-risk patients. Once these patients have been identified, clinicians must monitor risk state and intervene when necessary to prevent harm. Clinical practice is dominated by the assumption that increases in psychiatric symptoms elevate risk of imminent violence. This intensive study of patients (N = 132) at high risk for community violence is the first to evaluate prospectively the temporal relation between symptoms and violence. Symptoms were assessed with the Brief Symptom Inventory and threat/control override (TCO) scales. Results indicate that a high-risk patient with increased anger in 1 week is significantly more likely to be involved in serious violence in the following week. This was not true of other symptom constellations (anxiety, depression, TCO) or general psychological distress. The authors found no evidence that increases in the latter symptoms during 1 week provide an independent foundation for expecting violence during the following week.

Comparing indicators of sexual sadism as predictors of recidivism among adult male sexual offenders.

Objective: In this longitudinal study, the predictive validity of a psychiatric diagnosis of sexual sadism was compared with three behavioral indicators of sadism: index sexual offense violence, sexual intrusiveness, and phallometrically assessed sexual arousal to depictions of sexual or nonsexual violence. Method: Five hundred and eighty six adult male sexual offenders were assessed between 1982 and 1992, and these offenders were followed for up to 20-years postrelease via official criminal records. Assessment information included the Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnosis, offense characteristics, phallometric assessment results, and an actuarial risk measure (the Sex Offender Risk Appraisal Guide). Results: Predictive validity was demonstrated in univariate analyses for the behavioral indicators of sexual sadism (area under the curve [AUCs] from .58 to .62) but not psychiatric diagnosis (AUC = .54). Cox regression analyses revealed that phallometrically assessed sexual arousal to violence was still significantly associated with violent (including sexual) recidivism after actuarially estimated risk to reoffend was controlled. A psychiatric diagnosis of sexual sadism, in contrast, was unrelated to recidivism. Conclusions: The results support the use of more behaviorally operationalized indicators of sexual sadism, especially phallometric assessment of sexual arousal, and suggest the DSM criteria for sexual sadism require further work.

Family Intervention for Suicide Prevention: A specialized emergency department intervention for suicidal youths.

Suicide attempts and suicidal ideation are common problems among youths seen in clinical practice. Despite the high risk of repeated suicidal behavior in these patients, clinicians are faced with a lack of empirically supported treatments for these youths. This article describes the Family Intervention for Suicide Prevention (FISP), a second-generation adaptation of the Specialized Emergency Room Intervention, an evidence-based practice. Although designed for use in emergency settings, the FISP can be used by practitioners working in a wide range of settings where youths present with suicidal emergencies. Rooted in cognitive–behavioral and family systems theory, the FISP is designed to mobilize family support and problem solving, reframe the suicide attempt as a critical event that requires treatment, reinforce more adaptive coping, motivate patients and families to initiate and adhere to follow-up treatment, and promote linkage to follow-up care. This approach can be used with a wide range of patients and offers an evidence-informed tool for practicing clinicians. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Improving the clinical practice of violence risk assessment: Technology, guidelines, and training.

Despite a long history of interest in, and criticism of, the ability of mental health professionals to assess and predict violence, there have been few efforts to develop or evaluate interventions to improve decision making in this area. This article provides a brief overview of recent research developments on violence risk. Drawing on these advances, 3 recommendations are outlined for improving the clinical practice of risk assessment: (a) to improve assessment technology, (b) to develop clinical practice guidelines, and (c) to develop training programs and curricula.

Peer Influence on Risk Taking, Risk Preference, and Risky Decision Making in Adolescence and Adulthood: An Experimental Study.

In this study, 306 individuals in 3 age groups--adolescents (13-16), youths (18-22), and adults (24 and older)--completed 2 questionnaire measures assessing risk preference and risky decision making, and 1 behavioral task measuring risk taking. Participants in each age group were randomly assigned to complete the measures either alone or with 2 same-aged peers. Analyses indicated that (a) risk taking and risky decision making decreased with age; (b) participants took more risks, focused more on the benefits than the costs of risky behavior, and made riskier decisions when in peer groups than alone; and (c) peer effects on risk taking and risky decision making were stronger among adolescents and youths than adults. These findings support the idea that adolescents are more inclined toward risky behavior and risky decision making than are adults and that peer influence plays an important role in explaining risky behavior during adolescence.

Documenting life-support preferences in hospitalized patients

PURPOSE: The purpose of this article was to determine the extent to which patients at high risk of hospital death who undergo cardiopulmonary resuscitation (CPR) have previously had their life support preferences addressed and documented. MATERIALS AND METHODS: We conducted a retrospective chart review of all patients older than 18 years of age hospitalized for more than 24 hours who sustained a cardiac arrest with attempted CPR at our tertiary care university teaching hospital during 1994 (n = 71). We searched all hospital charts specifying ICD-9 codes: Cardiac arrest, ventricular fibrillation, ventricular tachycardia, asystole, electromechanical dissociation, defibrillation, or CPR. Patients were selected if (1) they had a true cardiac arrest (abrupt cessation of spontaneous circulation) and (2) had attempted CPR or defibrillation. Patients were classified as "high risk" if they satisfied at least one of the following: modified prearrest morbidity index > or = 7, moderate/severe dementia, day 1 APACHE II score > 24 or > or = 4 dysfunctional organ systems. RESULTS: We searched 147 charts; of 71 patients meeting inclusion criteria, 53 were high risk. Of patients at high risk of sustaining a cardiopulmonary arrest during the index hospital admission, 3 (6%) had preferences addressed within the first 24 hours of hospitalization, 7 (13%) had delayed discussion of preferences before arrest, 23 (43%) had preferences addressed post arrest, and 20 (38%) had no documented discussions. Of the 23 high-risk patients initially surviving cardiac arrest, all were subsequently given "do not resuscitate" orders. Univariate analysis of factors associated with life-support discussion before cardiac arrest were previous cardiac arrest (OR, 5.9) and APACHE II score > 24 (OR, 1.1), although neither reached statistical significance. None of the 32 patients with a modified PAM index > or = 7 (32 of 71) survived hospitalization. Only 3 patients survived to hospital discharge. CONCLUSIONS: Early communication regarding life-support preferences is important in high-risk patients so that inappropriate or unwanted treatment is not implemented. Given that optimal care includes addressing and documenting life-support preferences in high-risk patients early in their hospitalization, this standard was infrequently met.     

Risk assessments for acute violence to third parties: a review of the literature

OBJECTIVES: To provide an overview of risk assessments for acute violence to third parties by combining a clinical and research focus and to offer guidelines to physicians conducting clinical assessments. METHOD: A computerized literature search of the MEDLINE and PSYCHINFO data bases from 1967 to 1996 was completed using the key words violence, aggression, dangerous behaviour, risk, risk assessment, risk factors, and practice guidelines. The search yielded 116 relevant references, 26 of which were original research articles on risk factor identification. A secondary search, based on the citations from the primary search, yielded an additional 8 general discussion articles. RESULTS: Risk assessments may be conducted using different methods, although all methods should be systematic and comprehensive. Research shows that risk assessments do have validity for use in short-term prediction and that it is possible to develop clinical guidelines in this area. A combined clinical and research approach holds the most promise for improving the accuracy of probability estimates, and most published guides and tools rely on such a combination. CONCLUSIONS: Risk assessments are an important and necessary part of the clinical examination. Because this field has sufficiently evolved, there is abundant literature to refer to when determining what constitutes an acceptable assessment for risk of violence to third parties and when it is appropriate to conduct such an examination.     

The Prediction of Violence and Homicide in Young Men.

In this prospective study, the authors predicted violence and homicide in 3 representative school samples (N = 1,517). Participants were part of a longitudinal, multiple cohort study on the development of delinquency in boys from late childhood to early adulthood in Pittsburgh, Pennsylvania. Thirty-three participants were convicted of homicide, 193 participants were convicted of serious violence, whereas another 498 participants self-reported serious violence. Predictors of violence included risk factors in the domains of child, family, school, and demographic characteristics. Boys with 4 or more violence risk factors were 6 times more likely to later commit violence in comparison with boys with fewer than 4 risk factors (odds ratio [OR] = 6.05). A subset of risk factors related to violence also predicted homicide among violent offenders. Boys with 4 or more risk factors for homicide were 14 times more likely to later commit homicide than violent individuals with fewer than 4 risk factors (OR = 14.48). Implications for the prevention of violence and homicide are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
