Clinical factors related to admission and release decisions in psychiatric emergency services

OBJECTIVE: The purpose of the study was to identify important clinical variables that influence admission and release decisions in psychiatric emergency services. METHODS: Physicians at four urban psychiatric emergency services rated 465 patients on ten clinical dimensions, including depression and psychosis. Information on five other variables-age, gender, ethnicity, diagnosis, and previous inpatient admission-were extracted from the patients' charts, as was information on case disposition. RESULTS: Logistic regression produced a model with five variables that significantly predicted admission or release. In order of importance, they were level of danger to self, severity of psychosis, ability to care for self, impulse control, and severity of depression. The model explained 51 percent of the variance in case disposition and correctly classified 84 percent of the cases. CONCLUSIONS: Guidelines addressing the variables that should be considered in making disposition decisions in psychiatric emergency services should be developed. The study found five variables that should be considered for inclusion.     

The role of violence in decisions about hospitalization from the psychiatric emergency room.

OBJECTIVE: The authors evaluated the relationship between violent behavior and decision making about hospitalization from the psychiatric emergency room. METHOD: The medical charts of 321 patients evaluated in an urban psychiatric emergency room during a 4-week period were reviewed retrospectively. Violent behavior was defined as physical attacks on persons or fear-inducing behavior before or during the evaluation in the emergency room; and its value in predicting hospitalization decisions was assessed with logistic regression analyses that also included 12 demographic, clinical, and contextual variables. RESULTS: A model predicting hospitalization decisions was developed and cross-validated. Although violent patients were more likely to be hospitalized than nonviolent patients, clinical variables such as diagnosis and overall severity of psychiatric impairment were more important than violent behavior in predicting hospitalization decisions. CONCLUSIONS: Despite legal pressures to focus on overt behaviors such as violence as a basis for liability prevention and civil commitment, clinicians in this study did not allocate inpatient resources to preventively detain persons unlikely to benefit from treatment. Rather, they hospitalized the most severely disturbed patients, with diagnoses such as schizophrenic and manic disorders for which a widely accepted therapeutic armamentarium exists. The results are consistent with clinical recommendations that in the evaluation of the violent patient, attention needs to be given to the underlying disorder, since violent behavior itself can result from diverse causes only some of which require inpatient psychiatric treatment.     

Patient-disease characteristics and coping strategies predict hospitalization in emergency psychiatry.

OBJECTIVE: The goal of this study was to analyze how far patient-disease characteristics (sociodemographic variables, previous psychiatric treatment, way of referral, the patient's current diagnosis), and the patient's coping strategies are connected with the consecutive disposition for inpatient or outpatient treatment. METHODS: Data from a one-year intake of the psychiatric emergency service at a University Hospital (N = 1439) were monitored and analyzed with regard to the decision on treatment. Four hundred eighty-one patients were hospitalized and 530 were assigned to outpatient treatment. Two subsamples of twenty-eight patients from each group filled out the Bernese Coping Modes questionnaire before the decision with regard to the treatment disposition was taken. RESULTS: The patient's psychiatric history, the way of referral as well as the current axis I diagnosis made a significant contribution to the treatment decision. Overall, patient-disease characteristics allowed for correct classification of 69.3 percent of cases. However, coping was a comparable predictor of hospitalization. CONCLUSIONS: It is argued that the search for patient-disease characteristics in the psychiatric emergency room should be complemented by a more extensive monitoring of the patients' way of coping with their current crisis.     

Patient and contextual factors related to the decision to hospitalize patients from emergency psychiatric services

OBJECTIVE: Mental health care reform has brought an increasing emphasis on community care, with concomitant reductions in inpatient psychiatric resources. Hospitalization remains a necessary and integral component of the mental health care system, but it is taking on a more specialized role. Examining the circumstances in which hospitalization is indicated can help clarify emergency psychiatric practices and determine whether patients' needs are being met within this changing environment. This pilot study examined the impact of selected patient and contextual characteristics on the decision to admit patients to inpatient psychiatric units and assessed the utility of the Severity of Psychiatric Illness (SPI) scale for monitoring clinical practice in emergency psychiatric services. METHODS: Crisis workers in two emergency psychiatric services crisis teams in Toronto, Canada, used the SPI in the assessment of 205 visitors to the services during the winter of 1998-1999. Contextual characteristics, including bed availability, service site, and the admitting physician's level of training, were recorded. Multivariate logistic regression was used to assess the relative contribution of patient and contextual variables in the admission decision. RESULTS: The severity of axis I symptoms and difficulties with self-care were significantly associated with the decision to admit. Site, bed availability, and the admitting physician's level of training did not appear to be associated with clinical decisions. CONCLUSIONS: Patients with the most need are being admitted to inpatient units despite significant systemic pressures on inpatient services. The SPI is a useful and discriminating tool for evaluating clinical practice in emergency services.     

Psychiatric emergency services in a Canadian city: II. Clinical characteristics and patients' disposition.

The clinical characteristics of patients seen at the psychiatric emergency facilities in a Canadian city and the determinants of decisions regarding their treatment were investigated. A total of 544 patients who sought psychiatric emergency services from the three hospitals in Saskatoon during a three month period were studied. Cognitive disturbance, past psychiatric history, previous psychiatric hospitalization and diagnoses of substance use disorders, affective disorders, anxiety disorders and schizophrenic disorders were associated with psychiatric emergencies. Psychiatric diagnoses and availability of social support were significantly associated with disposition. The implications of these findings for psychiatric emergency services are discussed.     

Les variables associées à la décision d’hospitalisation

The psychiatric assessment conducted in a psychiatric emergency service and the subsequent admission decisions have major psychological, physical and fiscal effects on patients, families and the community. Despite the importance of the task, there is no agreement on the areas of clinical assessment the psychiatric emergency service should focus on. The purpose of this study was to identify important variables that influence admission decisions in psychiatric emergency services in order to provide information facilitating the development of assessment guidelines for use in the psychiatric emergency services. Residents at the psychiatric emergency service rated prospectively 326 patients (sex ratio: 1.91, mean age: 34.55 years (S.D. = 11.68), unemployment: 74.5%, low educational level: 60.7%; low socioeconomic level: 77.9%, married: 29.4%, rural residence: 51.8%, of the 326 patients, 218 (66.9 %) were hospitalized) on 12 clinical and demographic variables, including gender, marital status, socioeconomic level, unemployment, danger to self, danger to others, referred to by psychiatric physicians, self referred, psychotic signs, current diagnostic of major mental illness, involuntary consultation, and previous hospitalisation. First, a chi square analyse was conducted on the 12 variables to determine whether they significantly differentiated patients admitted from those released. A p value below 0.05 was used. Next, a binary logistic regression procedure was employed to develop a model for an admission depending on five variables. The SPSS software program was used for these analyses. The model's performance was evaluated in two ways: the proportion of cases correctly classified and the level of signification of the Hosmer-Lemeshow test. A logistic regression produced a model with five variables that significantly predicted admission, in order of importance they were danger to self, psychotic signs, current diagnostic of major mental illness, involuntary consultation, and danger to others. The model correctly classified 93.9 percent of the cases. The level of signification of the Hosmer-Lemeshow test was 0,724 (chi-square = 5.307, ddl = 8). A review of results of similar studies in other populations shows that these findings are supported in the literature. As a result, these five variables should be included in admission Guidelines for emergency psychiatric services staff. In this study, the admission decisions were usually justified.     

Factors affecting psychiatric inpatient hospitalization from a psychiatric emergency service

Objective

As a gateway to the mental health system, psychiatric emergency services (PES) are charged with assessing a heterogeneous array of short-term and long-term psychiatric crises. However, few studies have examined factors associated with inpatient psychiatric hospitalization following PES in a racially diverse sample. We examine the demographic, service use and clinical factors associated with inpatient hospitalization and differences in predisposing factors by race and ethnicity.

Method

Three months of consecutive admissions to San Francisco’s only 24-h PES (N = 1,305) were reviewed. Logistic regression was used to estimate the associations between demographic, service use, and clinical factors and inpatient psychiatric hospitalization. We then estimated separate models for Asians, Blacks, Latinos and Whites.

Results

Clinical severity was a consistent predictor of hospitalization. However, age, gender, race/ethnicity, homelessness and employment status were all significant related to hospitalization. Alcohol and drug use were associated with lower probability of inpatient admission, however specific substances appear particularly salient for different racial/ethnic groups.

Discussion

While clinical characteristics played an essential role in disposition decisions, these results point to the importance of factors external to PES. Individual and community factors that affect use of psychiatric emergency services merit additional focused attention.     

The Nordic comparative study on sectorised psychiatry: repeated emergency admissions to inpatient care during a 1-year follow-up

The emergency admissions to hospital care in six psychiatric services in four Nordic countries were explored as a part of a Nordic comparative study on sectorised psychiatry. One year treated incidence cohorts were used, with the total cohort comprising 2,454 patients. Of the 803 patients who were admitted to inpatient care during a 1-year follow-up, 82% had at least one emergency admission and 23% repeated emergency admissions. The definition for the repeated emergency admissions was at least two admissions during the follow-up. The mean length of stay in emergency inpatient care per treatment episode for this patient subgroup was 28 days. Their emergency inpatient episodes constituted 30% of all inpatient days during the follow-up. However, the variations between the services and diagnostic subgroups were large. The results of a logistic regression analysis indicated that the following variables predicted repeated emergency admissions: inpatient care at index contact, emergency outpatient contacts or no planned hospital admissions during the follow-up, psychiatric service, age under 45 years, and a diagnosis of psychosis, personality disorder or dependency. The repeated emergency admissions were related to the existence of a special service unit for abusers but not to the rates of outpatient staff or acute beds in the services, to geographical distances, referral practice or existence of emergency services.     

Attempted suicide: factors leading to hospitalization.

OBJECTIVE: This study analyzes how sociodemographic and clinical characteristics influence the treatment decision for patients referred to a university hospital emergency room (ER) owing to attempted suicide. METHOD: Using a cross-sectional design, we monitored all patients admitted to a university hospital ER after attempting suicide, over a 3-year period (n = 404). Treatment decisions were categorized into 3 groups: inpatient treatment, outpatient treatment, and no further treatment. RESULTS: Older patients were more likely to be hospitalized, while women and patients with regular occupational activity were more likely to receive outpatient treatment. In logistic regression analysis, attempted suicide using aggressive methods, history of psychiatric inpatient treatment, and psychotic disorders were associated with inpatient treatment. Adjustment and neurotic disorders were related to outpatient treatment. CONCLUSIONS: The decision to hospitalize can be satisfactorily predicted by means of sociodemographic and clinical characteristics, while the number of patients assigned to outpatient treatment is underestimated. A triage that relies only on sociodemographic and clinical data as well as risk factors could result in too frequent admissions of patients after attempted suicide.     

Relationships between patient, family, and significant other disposition preferences in psychiatric emergency services and the clinical symptom ratings and disposition decisions of psychiatrists

A previous paper examined the relationship between 10 clinical ratings made by psychiatrists and 465 psychiatric emergency service (PES) dispositions. A logistic regression model explained 52% of the variance in the psychiatrist's decisions to admit to inpatient services or release. The 5 clinical ratings in the model, rated on 8-point scales, were severity of danger to self, psychosis, inability to care for self, impulse control, and depression. The current paper examines the relationships between patient and family/significant other dispositional preferences expressed in the PES, and the psychiatrist's disposition decision and the 10 clinical ratings. It found that the dispositional preferences of the patient, family, and other individuals (community clinician, police, or ambulance driver) were very consistent with the actual decision made by the PES psychiatrist. Further, it found that these preferences explained an additional 35% of the variability in the psychiatrist's decision to admit or release. Finally, the ten clinical ratings made by the PES psychiatrist explained only a small amount of the variance in the dispositional preferences, and some of the significant coefficients were in the opposite direction expected. Patient, family and other significant individuals' expressed preferences and expectations in the PES are important and should be routinely recorded in the charts. The small relationships between clinical ratings and preferences suggests that the reasons the family/significant other and the patient seeks hospital admission or release may differ with psychiatrists' reasons for disposition.     

Predicting hospitalization versus discharge of suicidal patients presenting to a psychiatric emergency service

OBJECTIVE: Suicidal ideation frequently prompts visits to psychiatric emergency departments, and more information is needed about factors that mediate clinicians' decisions to hospitalize or discharge patients with suicidal ideation. METHODS: The authors reviewed records for 257 patients presenting with suicidal ideation to a psychiatric emergency service. Demographic and clinical correlates of hospitalization were examined by backward stepwise binary logistic regression. RESULTS: Hospitalization occurred for 70% of suicidal persons and was significantly associated with psychosis, a history of attempted suicide, and a suicidal plan. With potential confounding factors controlled, these variables correctly classified 80% of hospitalization decisions. CONCLUSIONS: Psychosis, past suicide attempts, and the presence of a suicide plan robustly predicted the decision to hospitalize suicidal persons seen in psychiatric emergency services. Diagnosis, pharmacotherapy, having a psychiatrist, and insurance subtype were unrelated to hospitalization decisions, suggesting that psychiatric emergency department staff perceive few alternatives to hospitalization when psychosis and suicide plans accompany suicidal ideation.     

Determinants of psychiatric inpatient admission to general hospital psychiatric wards: an epidemiological study in a region of central Italy

Objective: To determine which factors contribute to the decision to admit individuals to psychiatric wards in general hospitals. Method: Data on 1,379 individuals undergoing psychiatric evaluation in eight emergency rooms in a region of central Italy were collected. A logistic regression analysis was used to evaluate the likelihood of psychiatric admission considering the independent effects of demographic, social, and clinical factors and of the history of psychiatric treatment. Results: The adjusted odds ratio for psychiatric admission significantly increased with the following variables: severity of symptoms; presence of paranoid states and schizophrenic psychoses, affective psychoses and acute psychotic conditions (with neurotic disorders used as reference); a history of outpatient treatment; the presence of a staff member of a community mental health facility upon presentation at the emergency room; and the availability of beds in the psychiatric ward. Conclusion: The independent effect played by the presence of a staff member of a community mental health facility is of particular interest, suggesting the existence of a collaborative relationship between inpatient and outpatient services.

Feasibility of dialectical behavior therapy for suicidal adolescent inpatients

OBJECTIVE: To evaluate the feasibility of dialectical behavior therapy (DBT) implementation in a general child and adolescent psychiatric inpatient unit and to provide preliminary effectiveness data on DBT versus treatment as usual (TAU). METHOD: Sixty-two adolescents with suicide attempts or suicidal ideation were admitted to one of two psychiatric inpatient units. One unit used a DBT protocol and the other unit relied on TAU. Assessments of depressive symptoms, suicidal ideation, hopelessness, parasuicidal behavior, hospitalizations, emergency room visits, and adherence to follow-up recommendations were conducted before and after treatment and at 1-year follow-up for both groups. In addition, behavioral incidents on the units were evaluated. RESULTS: DBT significantly reduced behavioral incidents during admission when compared with TAU. Both groups demonstrated highly significant reductions in parasuicidal behavior, depressive symptoms, and suicidal ideation at 1 year. CONCLUSIONS: DBT can be effectively implemented in acute-care child and adolescent psychiatric inpatient units. The promising results from this pilot study suggest that further evaluation of DBT for adolescent inpatients appears warranted.     

A comparison in hospitalization rates between a community-based mobile emergency service and a hospital-based emergency service

OBJECTIVES: The aims of this study were to compare the rates of inpatient admission between a mobile community-based psychiatric emergency service and a hospital-based psychiatric emergency service, and to identify the clinical characteristics of consumers more likely to be admitted to hospital. METHODS: A retrospective, quasi-experimental design was used with a 3-month cohort of all face-to-face emergency service contacts presenting at the mobile and hospital-based sites. The Health of the Nation Outcome Scales and details of the outcome following initial assessment were completed for all contacts, and each group was compared for differences in clinical characteristics and outcome. RESULTS: Hospital-based emergency service contacts were found to be more than three times as likely to be admitted to a psychiatric inpatient unit when compared with those using a mobile community-based emergency service, regardless of their clinical characteristics. Those with severe mental health disorders such as schizophrenia and major affective disorder, and experiencing problems with aggression, non-accidental self-injury, hallucinations and delusions, problems with occupation, activities of daily living, and living conditions were more likely to be admitted to hospital. Nevertheless, after controlling for clinical characteristics, site of initial assessment accounted for a substantial proportion of the variance in decisions to admit to hospital. CONCLUSIONS: Emergency psychiatric services which include a mobile component and provide a specialized multidisciplinary team approach appear to be most effective in providing services in the least restrictive environment and avoiding hospitalization.     

The role of race in diagnostic and disposition decision making in a pediatric psychiatric emergency service

OBJECTIVE: We investigated the influence of race/ethnicity in diagnostic and disposition decision-making for children and adolescents presenting to an urban psychiatric emergency service (PES). METHOD: Medical records were reviewed for 2991 child and adolescent African-American, Hispanic/Latino and white patients, treated in an urban PES between October 2001 and September 2002. A series of bivariate and binomial logistic regression analyses were used to delineate the role of race in the patterns and correlates of psychiatric diagnostic and treatment disposition decisions. RESULTS: Binomial logistic regression analyses reveal that African-American (OR=2.28, P<.001) and Hispanic/Latino (OR=2.35, P<.05) patients are more likely to receive psychotic disorders and behavioral disorders diagnoses (African American: OR=1.66, P<.001; Hispanic/Latino: OR=1.36, P<.05) than white children/adolescents presenting to PES. African-American youth compared to white youth are also less likely to receive depressive disorder (OR=0.78, P<.05), bipolar disorder (OR=.44, P<.001) and alcohol/substance abuse disorder (OR=.18, P<.01) diagnoses. African-American pediatric PES patients are also more likely to be hospitalized (OR=1.50, P<.05), controlling for other sociodemographic and clinical factors (e.g., Global Assessment of Functioning). CONCLUSIONS: The results highlight that nonclinical factors such as race/ethnicity are associated with clinical diagnostic decisions as early as childhood suggesting the pervasiveness of such disparities.     

Emergency psychiatric assessment of violence

OBJECTIVE: The purpose of the study was to 1) ascertain whether there are clinical and demographic characteristics that distinguish dangerous from nondangerous patients evaluated in a psychiatric emergency service and 2) identify variables that distinguish dangerous patients who are hospitalized form those who are not. METHOD: The authors conducted a case comparison study of 99 psychiatric emergency patients whom staff identified as dangerous to others, that is, violent or potentially violent. Clinical staff were interviewed and records reviewed. These data were contrasted with record review data for 95 nondangerous patients. RESULTS: Log linear analysis showed that 1) variables relating to violence in community samples--age, sex, and past history of violence--related minimally or not at all to violence in this sample and 2) disposition to hospital versus community was associated with psychotic mental status and restraint in the psychiatric emergency service. Patients requiring restraint were more likely to have recently committed assault or battery and to have been brought in by the police. CONCLUSIONS: Enduring personal characteristics of patients relate neither to psychiatric emergency service assessments of current dangerousness nor to the decision to hospitalize. These determinations appear to be related to assessments of current patient state and immediate past behavior.     

Psychiatric episodes in general hospitals without psychiatric units

Forty percent of inpatient psychiatric episodes are treated in general hospitals without psychiatric units, but little is known about these patients and their treatment. A survey of medical records personnel at 452 hospitals without psychiatric units revealed that the hospitals' psychiatric patients typically lived at home, were admitted through the emergency room because of a substance abuse disorder, received active medical treatment, were discharged back home after about four days, and paid with private insurance. The hospitals that treated primarily substance abusers provided a significantly different mix of treatments than did those that treated primarily patients with traditional diagnoses. The data suggest that general hospitals without psychiatric units may provide appropriate treatment for psychiatric patients, especially those with a substance abuse disorder.     

Treatment for co-occurring mental and substance use disorders in five state Medicaid programs

OBJECTIVES: This study described the locations and patterns of psychiatric and substance abuse treatment for Medicaid beneficiaries with co-occurring mental and substance use disorders in five states. METHODS: Medicaid beneficiaries aged 21 to 65 with psychiatric or substance use disorders were identified with claims and encounter records. Groups were further divided into those with and those without a diagnosed substance use disorder. Adjusted odds of treatment in community-based settings, inpatient facilities, emergency departments, and hospital outpatient departments were calculated. RESULTS: A total of 92,355 persons had a psychiatric disorder, 34,158 had a substance use disorder, and 14,256 had co-occurring psychiatric and substance use disorders. In all five states, beneficiaries with severe mental illness (schizophrenia, bipolar disorder, or major depression) and a substance use disorder had higher odds of inpatient, emergency department, and hospital-based outpatient psychiatric treatment, compared with those with severe mental illness alone. In four of five states, both severe and less severe mental illness and a co-occurring substance use disorder were associated with lower odds of community-based treatment compared with those with the respective mental illness alone. Compared with those with less severe mental illness alone, individuals with less severe psychiatric disorders and a co-occurring substance use disorder had higher odds of inpatient treatment in all states and of emergency department use in three of five states. Odds of inpatient and outpatient hospital use and emergency department use for substance abuse treatment were higher for persons with severe mental illness and a co-occurring substance use disorder in most states, compared with odds for those with a substance use disorder alone. CONCLUSIONS: Heavy inpatient and emergency department use by Medicaid beneficiaries with co-occurring substance use disorders is a consistent cross-state problem. Co-occurring disorders may decrease the likelihood of community-based treatment for those with less severe mental disorders and for those with severe mental illness, suggesting that policies focusing only on these settings may miss a significant proportion of people with these co-occurring disorders.     

Determinants of emergency psychiatric admission for adolescents and adults

The authors compared correlates of admission for 100 patients older than 18 years and 100 patients younger than 18 evaluated in a psychiatric emergency service. Stepwise linear logistic regression analysis identified a combination of variables that best predicted the odds of hospitalization for each group. For adolescents, these variables, in order of importance, were suicidal tendencies, physical abuse, a primary diagnosis of schizophrenia, age, and number of suicide attempts. For adults, the variables were delusions, aggressive behavior, suicidal tendencies, and a primary diagnosis of schizophrenia or affective disorder. The authors discuss the implications of these findings for acute psychiatric treatment of adolescents.     

Home-based multisystemic therapy as an alternative to the hospitalization of youths in psychiatric crisis: clinical outcomes

OBJECTIVE: The primary purpose of this study was to determine whether multisystemic therapy (MST), modified for use with youths presenting psychiatric emergencies, can serve as a clinically viable alternative to inpatient psychiatric hospitalization. METHOD: One hundred sixteen children and adolescents approved for emergency psychiatric hospitalization were randomly assigned to home-based MST or inpatient hospitalization. Assessments examining symptomatology, antisocial behavior, self-esteem, family relations, peer relations, school attendance, and consumer satisfaction were conducted at 3 times: within 24 hours of recruitment into the project, shortly after the hospitalized youth was released from the hospital (1-2 weeks after recruitment), and at the completion of MST home-based services (average of 4 months postrecruitment). RESULTS: MST was more effective than emergency hospitalization at decreasing youths' externalizing symptoms and improving their family functioning and school attendance. Hospitalization was more effective than MST at improving youths' self-esteem. Consumer satisfaction scores were higher in the MST condition. CONCLUSIONS: The findings support the view that an intensive, well-specified, and empirically supported treatment model, with judicious access to placement, can effectively serve as a family- and community-based alternative to the emergency psychiatric hospitalization of children and adolescents.
