Psychiatric emergency "surge capacity" following acts of terrorism and mass violence with high media impact: what is required?

OBJECTIVE: Adequate preparedness for acts of terrorism and mass violence requires a thorough understanding of the postdisaster mental health needs of all exposed groups, including those watching such events from a distance. This study examined emergency psychiatric treatment-seeking patterns following media exposure to four national terrorist or mass casualty events. METHOD: An event was selected for study if (a) it precipitated local front-page headlines for >5 consecutive days and (b) emergency service psychiatrists identified it as specifically precipitating help-seeking in the study hospital. Four events qualified: the Oklahoma City bombing (1995), the Columbine High School (1999) and Wedgewood Baptist Church (1999) shootings and the terrorist attacks of September 11, 2001. Time-series analyses were used to correct for autocorrelation in visit patterns during the postdisaster week, and equivalent time periods from years before and after each event were used as control years. RESULTS: Overall, disaster week census did not differ significantly from predisaster weeks, although 3-day nonsignificant decreases in visit rate were observed following each disaster. Treatment-seeking for anxiety-related issues showed a nonsignificant increase following each disaster, which became significant in the "all disaster" model (t=5.17; P=.006). Intensity of media coverage did not impact rate of help-seeking in any analysis. CONCLUSIONS: Although these sentinel US disasters varied in scope, method, geographic proximity to the study site, perpetrator characteristics, public response, sequelae and degree of media coverage, the extent to which they impacted emergency department treatment-seeking was minimal. Geographically distant mass violence and disaster events of the type and scope studied here may require only minimal mental health "surge capacity" in the days following the event.

The Psychiatric Emergency Research Collaboration-01: methods and results.

OBJECTIVE: To describe the Psychiatric Emergency Research Collaboration (PERC), the methods used to create a structured chart review tool and the results of our multicenter study. METHOD: Members of the PERC Steering Committee created a structured chart review tool designed to provide a comprehensive picture of the assessment and management of psychiatric emergency patients. Ten primary indicators were chosen based on the Steering Committee's professional experience, the published literature and existing consensus panel guidelines. Eight emergency departments completed data abstraction of 50 randomly selected emergency psychiatric patients, with seven providing data from two independent raters. Inter-rater reliability (Kappas) and descriptive statistics were computed. RESULTS: Four hundred patient charts were abstracted. Initial concordance between raters was variable, with some sites achieving high agreement and others not. Reconciliation of discordant ratings through re-review of the original source documentation was necessary for four of the sites. Two hundred eighty-five (71%) subjects had some form of laboratory test performed, including 212 (53%) who had urine toxicology screening and 163 (41%) who had blood alcohol levels drawn. Agitation was present in 220 (52%), with 98 (25%) receiving a medication to reduce agitation and 22 (6%) being physically restrained. Self-harm ideation was present in 226 (55%), while other-harm ideation was present in 82 (20%). One hundred seventy-nine (45%) were admitted to an inpatient or observation unit. CONCLUSION: Creating a common standard for documenting, abstracting and reporting on the nature and management of psychiatric emergencies is feasible across a wide range of health care institutions.

Telephone-based assessments to minimize missing data in longitudinal depression trials: a project IMPACTS study report.

PURPOSE: Missing data in clinical efficacy and effectiveness trials continue to be a major threat to the validity of study findings. The purpose of this report is to describe methods developed to ensure completion of outcome assessments with public mental health sector subjects participating in a longitudinal, repeated measures study for the treatment of major depressive disorder. We developed longitudinal assessment procedures that included telephone-based clinician interviews in order to minimize missing data commonly encountered with face-to-face assessment procedures. METHODS: A pre-planned, multi-step strategy was developed to ensure completeness of data collection. The procedure included obtaining multiple pieces of patient contact information at baseline, careful education of both staff and patients concerning the purpose of assessments, establishing good patient rapport, and finally being flexible and persistent with phone appointments to ensure the completion of telephone-based follow-up assessments. A well-developed administrative and organizational structure was also put in place prior to study implementation. RESULTS: The assessment completion rate for the primary outcome for 310 of 504 subjects who enrolled and completed 52 weeks (at the time of manuscript) of telephone-based follow-up assessments was 96.8%. CONCLUSION: By utilizing telephone-based follow-up procedures and adapting our easy-to-use pre-defined multi-step approach, researchers can maximize patient data retention in longitudinal studies.

Repeat suicide attempts in Hong Kong community adolescents.

It has been well documented that a history of suicide attempts confers risk for subsequent attempts; however, efforts to explain how variables may change after a previous attempt and in turn relate to future suicide attempts are rare in the literature. This study presents longitudinal data on adolescent suicide attempts in Hong Kong, and examines whether the data support the "crescendo" model to explain repeat suicide attempts. One thousand and ninety-nine community adolescents aged 12-18 years were evaluated at two assessment points 12 months apart (T1 and T2). The study assessed (1) risk factors at T1 for a suicide attempt between T1 and T2, (2) whether a suicide attempt during the 12 months prior to T1 predicted an attempt between the two assessment points, and (3) whether the indicators of distress worsened from T1 to T2 if an attempt had taken place in the interim. The results indicated that: (1) depressive symptoms, substance use, and suicidal ideation measured at T1 were independent predictors of a suicide attempt between T1 and T2; (2) suicide attempt in the year prior to T1 predicted suicide attempt between T1 and T2 after controlling for other predictors; and (3) suicide attempt between T1 and T2 was a predictive factor for a negative change from T1 to T2 in substance use, suicidal ideation, family relationships, depression, anxiety, and life stress. These findings are consistent with the "crescendo" model proposing that the risk of repeat attempts is enhanced following a previous suicide attempt.

Trends in emergency department use of gastric lavage for poisoning events in the United States, 1993-2003.

OBJECTIVE: To determine current trends in the use of gastric decontamination for the emergency department (ED) treatment of overdose patients. METHODS: In the National Health Ambulatory Medical Care Survey (NHAMCS), a weighted sampling of U.S. EDs, overdose-related visits were examined using ICD-9 CM E codes and NHAMCS' "reason-for-visit" classification. RESULTS: From 1993 to 2003 there were an estimated 11.68 million ED-treated poisoning events. Some 13.7% of those treated were lavaged. Rates fell significantly, from an annual average of 18.7% of cases during 1993-97 to 10.3% during 1998-2003 (p < 0.001). Controlling for year, urgency, and admission status in multivariate logistic modeling, lavage was significantly and positively associated with private insurance payor status, younger age (<30), female gender, white race, 8 PM-8 AM presentation, and intentional rather than unintentional overdose. CONCLUSION: ED use of gastric lavage in poisoned patients has decreased significantly over the past decade but varies by demographic and non-clinical factors.

Adolescent suicide attempters in Hong Kong and the United States.

Using a nested case-control design drawing from a larger sample of 2272 adolescents, this study examined the characteristics of adolescents from Hong Kong (n = 99) and the United States (US) (n = 60), who indicated that they had made a suicide attempt at least once in the past, compared to their equally depressed sex- and age-matched counterparts who had not attempted suicide. The cross-cultural literature suggested three hypotheses which were tested: (a) depressive symptoms would differentiate between suicide attempters compared to non-attempters less in Hong Kong and more in the US; (b) discord in interpersonal relationships would be a more important distinguishing factor in suicide attempts in Hong Kong than in the US and (c) cognitive variables such as hopelessness would be less associated with suicide attempts in Hong Kong compared to the US. There were strong similarities in the two cultures with regard to characteristics that distinguished between attempters and matched controls. Hypotheses regarding cultural differences between attempters in Hong Kong and the US were not supported. Depression, current and lifetime suicide ideation, hopelessness, poor interpersonal relationships and exposure to suicide attempters and completers distinguished attempters from controls equally in the two cultures and in both genders. These findings do not support the proposition that depression is a less relevant variable in suicide attempts in Chinese versus western groups.
