Epidemiology and characteristics of emergency departments visits by US adults with psychiatric disorder and antipsychotic mention from 2000 to 2004

Psychopathy in the Medical Emergency Department

Psychopathy is a personality disorder representing an admixture of a fearless and dominant temperament with an impulsive and antisocial orientation. A sample of 1,026 participants in the waiting room of the medical emergency department of a city hospital exhibited levels of fearless dominance similar to university undergraduates and federal inmates; their levels of impulsive antisociality fell between those of federal and state inmates. Both psychopathy factors were correlated with male gender, younger age, and more frequent average alcohol consumption. Fearless dominance was associated with agentic success (e.g., being employed, higher household income), fewer psychological problems, and less use of psychotropic medications, including anxiolytics. Impulsive antisociality was negatively related to both agentic and communal (e.g., ever being married) success and positively correlated with substance use and self-reported bipolar, ADHD, and psychotic psychiatric conditions. Further, only impulsive antisociality was associated with presenting to the emergency department for physical injury or psychological disturbance.

State of Acute Agitation at Psychiatric Emergencies in Europe: The STAGE Study

Background:

Agitation is an array of syndromes and types of behaviors that are common in patients with psychiatric disorders. In Europe, the estimation of prevalence of agitation has been difficult due to the lack of standard studies or systematic data collection done on this syndrome.

Objective:

An observational, cross-sectional, multicenter study aimed to assess the prevalence of agitation episodes in psychiatric emergencies in different European countries.

Method:

For 1 week, all episodes of acute agitation that were attended to at the psychiatric emergency room (ER) or Acute Inpatient Unit (AIU) in the 27 participating centers were registered. The clinical characteristics and management of the agitation episode were also described. A descriptive analysis was performed.

Results:

A total of 334 agitation episodes out of 7295 psychiatric emergencies were recorded, giving a prevalence rate of 4.6% (95% CI: 4.12-5.08). Of them, 172 [9.4% (95% CI: 8.2-10.9)] were attended at the ER and 162 [2.8% (95% CI: 2.4-3.3)] at AIU. Only data from 165 episodes of agitation (those with a signed informed consent form) was registered and described in this report. The most common psychiatric conditions associated with agitation were schizophrenia, bipolar disorder and personality disorder. The management of agitation included from non-invasive to more coercive measures (mechanical, physical restraint or seclusion) that were unavoidable in more than half of the agitation episodes (59.5%).

Conclusion:

The results show that agitation is a common symptom in the clinical practice, both in emergency and inpatient psychiatric departments. Further studies are warranted to better recognize (using a standardized definition) and characterize agitation episodes.

Patterns of Psychiatric Outpatient Practice in Taiwan: A Nationwide Survey

(1) Background: Limited studies have utilized nationwide data to assess the patterns of psychiatric practice in other countries. In this study, data from the National Health Insurance Research Database in Taiwan (NHIRD-TW) for 2012 was analyzed to determine the patterns of psychiatric outpatient practice in Taiwan; (2) Methods: To determine the patterns of psychiatric outpatient practice in Taiwan, the data were drawn from the datasets of Taiwan's National Health Insurance Research Database for 2012, with 619,760 records of outpatient visits representing 1/500 of all the claims in Taiwan for that year. The analysis of psychiatric outpatient visits included patient demographics, diagnoses, and prescribed medications; (3) Results: Neurotic disorders were the most prevalent diagnoses (43.1%, n = 5714). Hypnotics-sedatives and anxiolytics were prescribed in 51.7% (n = 6850) and 39.1% (n = 5181) of psychiatric visits, respectively, with zolpidem being the most commonly prescribed drug (22.6%, n = 2998); and (4) Conclusion: Hypnotics and sedatives were widely prescribed for the outpatient population, and zolpidem had the highest annual prevalence of use. These findings deserve the attention of clinicians and policy makers for monitoring the abuse and dependence of these agents and subsequent adverse events.

Controversies in the use of second generation antipsychotics as sleep agent

A growing number of patients present in clinics with complaints of insomnia. Over the past century, great advances have been made in our knowledge of mechanisms of sleep and wakefulness. Understanding sleep neurochemistry has led to better management of different types of insomnias with a variety of non-pharmacological and pharmacological treatments. Unfortunately, the increasing development and availability of second generation antipsychotics (SGA) have prompted their frequent use exclusively for insomnia. However, to date, no large randomized-controlled or placebo-controlled studies have shown the utility of SGAs in the realm of treating insomnia. Many clinicians use SGAs as "off-label" for sleep induction and maintenance, but this practice needs to be readdressed given their potential risks and the current lack of evidence base. This review will highlight the neurochemistry related to sleep, the mechanisms of action by which SGA may have some benefit in treating insomnia, and the risks associated with their utilization.

A review of pharmacoepidemiologic studies of antipsychotic use in children and adolescents

OBJECTIVE

In Canada, treatment of children and adolescents with antipsychotics is almost always off label. A single atypical agent, aripiprazole, only recently received regulatory authorization for use in the group aged 15 to 17 years. This regulatory approval was restricted to treatment of schizophrenia. The objective of this review was to summarize pharmacoepidemiologic reports examining the frequency of use of these medications.

METHODS

A literature search was used to identify English-language studies examining the pharmacoepidemiology of antipsychotics in children and adolescents. The results of identified studies were summarized using narrative review methods.

RESULTS

In countries where longitudinal data are available, increased antipsychotic use has been consistently observed. Generally, most or all of this increase can be attributed to second-generation antipsychotics (SGAs). Major international differences are evident in the literature. European studies describe lower overall frequencies of use than North American studies (most of which were conducted in the United States). SGAs in children and adolescents are used more often in boys than in girls, and are increasingly used for treatment of attention-deficit hyperactivity disorder (ADHD) and conduct disorder (CD).

CONCLUSIONS

Determining the most appropriate frequency of SGA use in children and adolescents will ultimately depend on decisive clarification of risks and benefits. The currently available literature highlights large international differences in the frequency of use. These differences may reflect fundamental dissimilarities in the therapeutic stance adopted toward ADHD and CD by physicians practicing in different countries.

Disparities in reproductive health-related visits to the emergency department in Maryland by age and race, 1999-2005

OBJECTIVE

To describe reproductive health-related visits to Maryland emergency departments (EDs) among women aged 15-44 years from 1999 to 2005.

METHODS

We obtained data from the Healthcare Cost and Utilization Project State Emergency Department Database and State Inpatient Database. ICD-9-CM diagnosis codes were used to classify reproductive health-related visits. We calculated the annual rate of reproductive health visits to Maryland EDs from 1999 to 2005 for women aged 15-44 years and tested time trends using linear regression. Admission rates were defined as the percentage of ED visits that resulted in inpatient admission. We calculated age-specific and race-specific rate ratios for diagnoses using Poisson regression and admission rate ratios using Cochran-Mantel-Haenszel statistics.

RESULTS

From 1999 to 2005, the rate of ED visits in Maryland increased 50%, from 28.0 to 42.1 visits per 1000 women. Lower genital tract infections were the most common diagnosis (21.4%). The rates were higher for women aged 15-24 than for women aged 25-44 (rate ratio 1.18, 95% confidence interval [CI] 1.17-1.18) and nearly three times higher for black women than white women (rate ratio 2.94, 95% CI 2.92-2.96). Admission rates were lower for women aged 15-24 than for women aged 25-44 (rate ratio 0.34, 95% CI 0.33-0.35) and were higher among black than white women (rate ratio 1.16, 95% CI 1.14-1.18).

CONCLUSIONS

Disparities by age and race are evident for reproductive health-related ED visits in Maryland, and many of these ED visits are for conditions that are amenable to preventive measures.

Emergency medicine and psychiatry agreement on diagnosis and disposition of emergency department patients with behavioral emergencies

OBJECTIVES

The objective was to determine the level of agreement between emergency physicians (EPs) and consulting psychiatrists in their diagnosis and disposition of emergency department (ED) patients with behavioral emergencies.

METHODS

The authors conducted a prospective study at a university teaching hospital ED with an annual census of approximately 45,000 patients. During study hours, each time a psychiatric consultation was requested, the emergency medicine (EM) and consulting psychiatry residents were asked to fill out similar short questionnaires concerning their diagnoses and disposition decisions after they consulted with their attending physicians. EM and psychiatry residents were blinded to the other's assessment of the patient. Residents were asked about their evaluation of patients regarding: 1) psychiatric assessments, 2) if the patients presented a danger to themselves or others or were gravely disabled, and 3) the need for emergency psychiatric hospitalization.

RESULTS

A total of 408 resident physician pairs were enrolled in the study. Patients ranged in age from 5 to 92 years, with a median age of 31 years; 50% were female. The most common psychiatric assessments, as evaluated by either EPs, consulting psychiatrists, or both, were mood disorder (66%), suicidality (57%), drug/alcohol abuse (26%), and psychosis (25%). Seventy-three percent were admitted for acute psychiatric hospitalization. Agreement between EPs and psychiatrists was 67% for presence of mood disorder, 82% for suicidality, 82% for drug/alcohol abuse, 85% for psychosis, and 85% for grave disability. There was 67% agreement regarding patient eligibility for involuntary psychiatric hold. EPs felt confident enough to make disposition decisions 87% of the time; for these patients there was 76% agreement with consulting psychiatrists about the final disposition decision.

CONCLUSIONS

The 67% agreement between EPs and consulting psychiatrists regarding need for involuntary hold, and 76% agreement regarding final disposition, demonstrate a substantial disagreement between EPs and psychiatrists regarding management and disposition of ED patients with psychiatric complaints. Further studies with patient follow-up are needed to determine the accuracy of the ED assessments by both EPs and consulting psychiatrists.

A randomized trial: are care navigators effective in connecting patients to primary care after psychiatric crisis?

Persons with serious mental illnesses suffer excess medical morbidity compared to the general population. This RCT aimed to determine whether navigators are effective in helping patients connect to primary care after psychiatric crisis. Adults presenting for emergency care were randomly assigned to a navigator versus usual care. Navigators facilitated access to primary care. Outcomes were connection rates to medical care and the impact of health insurance, hospitalization and mental health care on primary care attendance. After 1 year, the intervention group was statistically more likely to access care, versus controls (62.4 vs. 37.6%, P < .001). Navigators were effective in helping patients connect to primary care after a psychiatric crisis. Improved access to primary care is important given the complex chronic health problems of this vulnerable cohort.

Gender differences in psychotic bipolar mania

OBJECTIVE

This study examined gender differences in the prevalence and types of psychotic symptoms in bipolar mania.

METHODS

Participants were drawn from consecutive admissions to the psychiatric clinic in Chemnitz, Germany, in 2005. The diagnosis of bipolar disorder, manic episode was made within 24 hours of admission, and the severity of mania was assessed using the Young Mania Rating Scale (YMRS) and the German version of the Altman Self-Rating Mania Scale. Data collected for each patient included age at the onset of bipolar illness, number of previous episodes, social functioning between episodes, and duration of hospitalization for the index episode. Based on the Task Force for Methods and Documentation in Psychiatry system, psychotic symptoms were classified as hallucinations (visual, auditory, olfactory, tactile, acousma, somatic); delusions (paranoid, reference, guilt, grandeur, religious, erotomania, hypochondriac, poverty, jealousy); and ego disorder (thought control, thought broadcasting).

RESULTS

One hundred thirty-seven women and 109 men met the criteria for an acute manic episode, of whom 93 women and 62 men had psychotic symptoms. Compared with psychotic men, psychotic women had more delusions and hallucinations, both overall and per patient, and more delusions of reference and paranoid delusions. Psychotic women had more mixed states compared with psychotic men. Psychotic women differed from both psychotic men and nonpsychotic women on a number of clinical and social variables: they had higher YMRS scores and more previous episodes of depression despite an earlier onset of illness.

CONCLUSION

Women with bipolar mania exhibited a specific pattern of psychotic symptoms that appeared to be associated with greater severity of the acute episode, more mixed states, and a more severe course of illness.

Co-occurring mental illness and health care utilization and expenditures in adults with obesity and chronic physical illness

The objectives of the study were to compare health care expenditures between adults with and without mental illness among individuals with obesity and chronic physical illness. We performed a cross-sectional analysis of 2440 adults (older than age 21) with obesity using a nationally representative survey of households, the Medical Expenditure Panel Survey. Chronic physical illness consisted of self-reported asthma, diabetes, heart disease, hypertension, or osteoarthritis. Mental illness included affective disorders; anxiety, somatoform, dissociative, personality disorders; and schizophrenia. Utilization and expenditures by type of service (total, inpatient, outpatient, emergency room, pharmacy, and other) were the dependent variables. Chi-square tests, logistic regression on likelihood of use, and ordinary least squares regression on logged expenditures among users were performed. All regressions controlled for gender, race/ethnicity, age, martial status, region, education, employment, poverty status, health insurance, smoking, and exercise. All analyses accounted for the complex design of the survey. We found that 25% of adults with obesity and physical illness had a mental illness. The average total expenditures for obese adults with physical illness and mental illness were $9897; average expenditures were $6584 for those with physical illness only. Mean pharmacy expenditures for obese adults with physical illness and mental illness and for those with physical illness only were $3343 and $1756, respectively. After controlling for all independent variables, among adults with obesity and physical illness, those with mental illness were more likely to use emergency services and had higher total, outpatient, and pharmaceutical expenditures than those without mental illness. Among individuals with obesity and chronic physical illness, expenditures increased when mental illness is added. Our study findings suggest cost-savings efforts should examine the reasons for high utilization and expenditures for those with obesity, chronic physical illness, and mental illness.
