Case-control study of frequent visitors to an urban psychiatric emergency service

OBJECTIVE: The purpose of this study was to identify risk factors for people who use psychiatric emergency services repeatedly and to estimate their financial charges. METHODS: The authors used interviews and chart reviews to compare 74 patients who had six or more visits to an urban psychiatric emergency service in the 12 months before an index visit with 74 patients who had five or fewer visits. Multivariate logistic regression was used to identify independent risk factors. RESULTS: Independent risk factors for frequent visitors were self-reported hospitalization in the past 12 months, need for medications as the self-reported reason for seeking care, being homeless or living in an institution, and not giving the name of a friend or family member for interview. The level of burden for support of persons who were interviewed was low and did not differ between frequent and infrequent visitors. Compared with infrequent visitors, frequent visitors had greater utilization of inpatient and outpatient behavioral health services, general emergency services, and crisis residential services in the 12 months before the index visit and greater utilization of general emergency services and psychiatric emergency services in the three months after the index visit. Frequent visitors' median financial charge for those services was 16,200 US dollars greater (5.9 times greater) than that of infrequent visitors. CONCLUSIONS: Frequent visitors represent resource-poor mentally ill persons who have high levels of utilization of health care facilities besides psychiatric emergency services. Possible clinical interventions for these patients include focused medication reviews.     

The impact of capitated financing on psychiatric emergency services

OBJECTIVE: Studies of capitated financing of mental health services have generally focused on the cost and utilization of services. Relatively little research has addressed whether capitation has an impact on the effectiveness of the mental health system as a whole. This study examined the impact of capitation on hospital emergency department visits, a widely cited indicator of the effectiveness of the other components of the system. METHODS: In 1995 Colorado's Medicaid program instituted capitation for mental health services in two areas of the state, one in which reimbursement of not-for-profit providers was directly capitated and another in which not-for-profit providers partnered with a for-profit managed behavioral health organization. The analysis examined variation over time in the number of emergency department visits by adults who had a primary mental or substance use disorder. Using interrupted time-series methods, visits in areas where reimbursement was capitated were compared with visits in areas where providers continued to be reimbursed on a fee-for-service basis. A total of 105 weeks for each area was examined; capitation was implemented at week 53. RESULTS: The number of psychiatric emergencies treated in capitated areas declined by 814 (28 percent) below the 2,908 psychiatric emergencies expected from trends, cycles, and levels in fee-for-service areas. Findings were similar for for-profit and not-for-profit areas. The decrease persisted through the end of the first year after capitation. CONCLUSIONS: In Colorado the implementation of capitation was associated with a sustained decrease in utilization of psychiatric emergency services provided by hospital emergency departments. Our findings suggest that capitation does not necessarily reduce the quality of care provided to clients.     

Screening for and detection of depression, panic disorder, and PTSD in public-sector obstetric clinics

OBJECTIVE: This study assessed rates of detection and treatment of minor and major depressive disorder, panic disorder, and posttraumatic stress disorder among pregnant women receiving prenatal care at public-sector obstetric clinics. METHODS: Interviewers systematically screened 387 women attending prenatal visits. The screening process was initiated before each woman's examination. After the visit, patients were asked whether their clinician recognized a mood or anxiety disorder. Medical records were reviewed for documentation of psychiatric illness and treatment. RESULTS: Only 26 percent of patients who screened positive for a psychiatric illness were recognized as having a mood or anxiety disorder by their health care provider. Moreover, clinicians detected disorders among only 12 percent of patients who showed evidence of suicidal ideation. Women with panic disorder or a lifetime history of domestic violence were more likely to be identified as having a psychiatric illness by a health care provider at some point before or during pregnancy. All women who screened positive for panic disorder had received or were currently receiving mental health treatment outside the prenatal visit, whereas 26 percent of women who screened positive for major or minor depression had received or were currently receiving treatment outside the prenatal visit. CONCLUSIONS: Detection rates for depressive disorders in obstetric settings are lower than those for panic disorder and lower than those reported in other primary care settings. Consequently, a large proportion of pregnant women continue to suffer silently with depression throughout their pregnancy. Given that depressive disorders among perinatal women are highly prevalent and may have profound impact on infants and children, more work is needed to enhance detection and referral.     

Psychiatric emergency service use and homelessness, mental disorder, and violence

OBJECTIVE: This study examined relationships between homelessness, mental disorder, violence, and the use of psychiatric emergency services. To the authors' knowledge, this study is the first to examine these issues for all episodes of care in a psychiatric emergency service that serves an entire mental health system in a major city. METHODS: Archival databases were examined to gather data on all individuals (N=2,294) who were served between January 1, 1997, and June 30, 1997, in the county hospital's psychiatric emergency service in San Francisco, California. RESULTS: Homeless individuals accounted for approximately 30 percent of the episodes of service in the psychiatric emergency service and were more likely than other emergency service patients to have multiple episodes of service and to be hospitalized after the emergency department visit. Homelessness was associated with increased rates of co-occurring substance-related disorders and severe mental disorders. Eight percent of persons who were homeless had exhibited violent behavior in the two weeks before visiting the emergency service. CONCLUSIONS: Homeless individuals with mental disorders accounted for a large proportion of persons who received psychiatric emergency services in the community mental health system in the urban setting of this study. The co-occurrence of homelessness, mental disorder, substance abuse, and violence represents a complicated issue that will likely require coordination of multiple service delivery systems for successful intervention. These findings warrant consideration in public policy initiatives. Simply diverting individuals with these problems from the criminal justice system to the community mental health system may have limited impact unless a broader array of services can be brought to bear.     

Impact of permanent supportive housing on the use of acute care health services by homeless adults

OBJECTIVE: This analysis examined the impact of permanent supportive housing on the use of acute care public health services by homeless people with mental illness, substance use disorder, and other disabilities. METHODS: The sample consisted of 236 single adults who entered supportive housing at two San Francisco sites, Canon Kip Community House and the Lyric Hotel, between October 10, 1994, and June 30, 1998. Eighty percent had a diagnosis of dual psychiatric and substance use disorders. Administrative data from the city's public health system were used to construct a retrospective, longitudinal history of service use. Analyses compared service use during the two years before entry into supportive housing with service use during the two years after entry. RESULTS: Eighty-one percent of residents remained in permanent supportive housing for at least one year. Housing placement significantly reduced the percentage of residents with an emergency department visit (53 to 37 percent), the average number of visits per person (1.94 to .86), and the total number of emergency department visits (56 percent decrease, from 457 to 202) for the sample as a whole. For hospitalizations, permanent supportive housing placement significantly reduced the likelihood of being hospitalized (19 to 11 percent) and the mean number of admissions per person (.34 to .19 admissions per resident). CONCLUSIONS: Providing permanent supportive housing to homeless people with psychiatric and substance use disorders reduced their use of costly hospital emergency department and inpatient services, which are publicly provided.     

Medical emergency department utilization patterns among uninsured patients with psychiatric disorders

OBJECTIVE: This study examined medical emergency department utilization for patterns among uninsured patients with psychiatric disorders. METHODS: Billing records of 15,672 uninsured adult patients treated in the emergency department of an academic medical center in southeast Texas over a 12-month period were analyzed for information on demographic characteristics, diagnosis, number of emergency department visits, and hospitalization. RESULTS: Overall, 11.8% of the population was diagnosed as having at least one psychiatric disorder during an emergency department visit. Patients with psychiatric disorders had an increased risk of having multiple emergency department visits and hospitalization compared with patients without psychiatric disorders. The risk of multiple emergency department visits was particularly high for patients with either bipolar disorder or psychotic disorders. CONCLUSIONS: Uninsured patients with psychiatric disorders appear to be heavy users of medical emergency department services. These findings may be helpful in developing more efficient strategies to serve the mental health needs of the uninsured.     

Characteristics of primary care visits for individuals with severe mental illness in a national sample

Individuals with severe mental illness (SMI) are at risk for inadequate general medical and preventive care, but little is known about their visits for primary care. We performed a cross-sectional analysis of primary care physician visits from the National Ambulatory Medical Care Survey (NAMCS) 1993–1998 and compared visit characteristics for patients with and without SMI. SMI was defined from ICD-9 diagnoses and medications. Primary care visits for patients with SMI were more likely to be return visits, were longer, and were more likely to have scheduled follow-up than for patients without SMI. Obesity, diabetes, and smoking were reported approximately twice as frequently in visits for patients with SMI compared to patients without SMI. The percent of visits with preventive counseling and counseling targeted at chronic medical conditions was similar for both groups. Likely appropriate to their complex needs, patients with SMI using primary care tend to have more return visits, longer time with the physician and are more often scheduled for follow-up care; their preventive counseling appears similar to non-SMI visits.     

Use of general medical services among Medicaid patients with severe and persistent mental illness

OBJECTIVE: The aim of this study was to examine patterns of use of general medical services among persons with a severe and persistent mental illness enrolled in Medicaid from 1996 to 1998. METHODS: A total of 669 persons with a severe and persistent mental illness were identified by using statewide clinical criteria. A three-year database of Medicaid claims was developed to examine service use. The main outcome measures were use of outpatient services for a general medical problem, use of dental and vision services, and use of screening tests for women. Service use was examined by primary psychiatric diagnosis (schizophrenic, affective, paranoid, and anxiety disorders), and analyses controlled for the presence of a chronic medical condition, age, race, and sex. RESULTS: This study found high levels of service use for outpatient services but very low levels for primary and preventive services. Although 78 percent of persons with a schizophrenic disorder had an office-based visit during the three-year period, all persons with an anxiety disorder had such a visit. Sixty-nine percent of persons with a schizophrenic disorder had at least one emergency department visit, whereas 83 percent of those with an anxiety disorder had such a visit. Dental and vision visits and the use of mammograms and pap tests followed the same pattern; persons with a schizophrenic disorder had fewer visits and had less overall use than the other diagnostic groups. The use patterns across the four groups were significantly different in outpatient service use, dental and vision service use, and screening tests for women. Compared with persons with a schizophrenic disorder, those with an anxiety disorder were more likely to have had an office-based visit and to have received vision services, those with a paranoid disorder were more likely to have used dental services or received a mammogram, and those with an affective disorder were more likely to have had a pap test. CONCLUSION: Although this group of Medicaid patients with severe and persistent mental illness had access to providers, they received an unacceptably low level of preventive care. Use of health services for general medical problems differed somewhat by primary psychiatric illness.     

Demographic and clinical profiles of patients who make multiple visits to psychiatric emergency services

OBJECTIVE: The study identified clinical and sociodemographic characteristics of patients making multiple visits to a psychiatric emergency service. METHODS: Information was obtained for patients visiting a hospital psychiatric emergency service in Montreal from 1985 to 2000. Profiles were determined for four groups: one visit, two visits, three to ten visits, and 11 or more visits. To determine whether the profile for those with 11 or more visits was generalizable, data for patients visiting the main site and three other such services from 2002 to 2004 were similarly analyzed. RESULTS: At the main study site (1985 to 2000), patients with single visits accounted for 36% of the 29,569 visits. The 292 patients with 11 or more visits accounted for almost 21% of total visits. Timing of the visit-time of day and day of the week-did not differentiate between groups. However, time itself was important in identifying patients with 11 or more visits: use of 30-month observation periods resulted in identification of only 8% of this group. Patients with 11 or more visits were more likely to be diagnosed as having schizophrenia and as having a comorbid diagnosis and were generally younger at the index visit and more economically impaired than those in the other groups. Overall, and at two of the three other sites, schizophrenia was overrepresented in the highest user group. CONCLUSIONS: Most visits to the psychiatric emergency service were made by frequent users who had distinctive profiles, which are potentially useful for developing clinical strategies to reduce the impact of this patient group on this service.     

The design, implementation, and acceptance of a primary care-based intervention to prevent depression relapse

OBJECTIVE: This article describes the conceptual underpinnings, implementation, and participation rates of a twelve-month low-intensity primary care-based intervention to prevent depression relapse. The intervention was designed to address the inherent problems in delivery of effective maintenance treatment in a population based sample of primary care patients. METHODS: Patients at high risk of relapse based on psychiatric history who recovered from depression six to eight weeks after initiation of pharmacotherapy by their primary care physician were eligible; 194 were randomized to receive the intervention. The intervention combined education about depression, motivation-enhancing shared decision-making regarding the use of maintenance pharmacotherapy, and cognitive-behavioral strategies. The program included two visits with a Depression Prevention Specialist working in tandem with the primary care physician at the primary care clinic, with supervision and back up from a consulting psychiatrist, proactive follow-up telephone calls and mailed personalized feedback. RESULTS: Ninety-three percent of patients attended both in-person visits; 97 percent attended one visit. Eighty percent of patients completed all three follow-up telephone calls, and 85 percent returned at least one mailed feedback form; 48 percent returned all four forms. Offered a menu of options for self-management, most patients chose medication as well as a variety of behavioral strategies. At six months, 72 percent ofpatients and at twelve months 62 percent of patients remained on antidepressant medication. CONCLUSIONS: We conclude that it is feasible to integrate a low intensity, twelve-month relapse prevention intervention for depression into a primary care clinic.     

Determinants of emergency room visits for psychological problems in a general hospital

Determinants of emergency room visits for psychological reasons were studied prospectively for a four month period in an Indian General Hospital. Psychiatric emergencies constituted only 2% of all emergency visits. Most of the patients were new except for 7.4% who were already registered with the outpatient services of the psychiatry department. Males outnumbered females in a ratio of 2:1. Self-referrals constituted 77% of the samples; 21% of patients were brought by police. Two-thirds of the patients were brought owing to the severity of their clinical condition and the rest, one-third, for medico-legal and social reasons. Approximately 80% of the patients sought consultation within one month of the onset of illness episode. First episode of mental illness was within last one year of the emergency room visit in 60% patients. Past history of hospitalization for mental illness was obtained only in 10% of cases. The pattern suggested that there was no misuse of emergency services by psychiatric patients although 20% of the patients presented with social problems only which required social rather than psychiatric intervention.     

Psychiatric visits to general hospital clinics by elderly persons and younger adults

Findings of a study of mental health visits to general hospital outpatient clinics and emergency rooms by elderly persons and younger adults were compared with findings from an earlier survey of mental health visits to office-based physicians. In both studies, about half of the visits were to psychiatric clinics or to psychiatrists. However, the findings differed in that 43 percent of all visits to hospital clinics were for substance abuse, compared with only 4 percent of the visits to private physicians. Almost three-fourths of the hospital-based mental health visits by elderly patients were to psychiatric clinics, while only a third of the office visits by elderly patients were to psychiatrists. The authors discuss the policy implications of the high utilization of clinic services by elderly patients.     

Preadmission care as a new mental health performance indicator

OBJECTIVE: This study examined the relationship between receipt of preadmission outpatient care during the month before an episode of hospitalization and the patients' subsequent treatment. METHODS: A total of 37,852 psychiatric inpatients who were discharged from 122 Veterans Affairs medical centers between October 1, 1997, and March 31, 1998, were studied. Linear and logistic regression were used to examine the relationship between receipt of preadmission outpatient care and length of hospital stay, use of postdischarge aftercare, and readmission. RESULTS: Having at least one outpatient visit in the month before admission was associated with a significantly shorter inpatient stay (16 days compared with 26 days, a difference of more than 60 percent) and with significantly greater use of postdischarge aftercare (odds ratio=1.83). However, the number of outpatient visits beyond one visit in the month before admission did not increase the effect on length of stay. These effects were strongest among patients with schizophrenia. CONCLUSIONS: Patients who have received outpatient care before hospital admission have shorter hospital stays and are more likely to use postdischarge aftercare than those who have not received outpatient care in the month before admission. Receipt of preadmission care itself rather than the intensity of such care seems to be the greatest predictor of length of stay.     

Locus of mental health treatment in an integrated service system

OBJECTIVE: Epidemiological surveys suggest that half of mental disorders in the community are treated in general medical settings. This paper examines delivery of mental health services in psychiatric, primary care, and specialty medical clinics in the Department of Veterans Affairs (VA), the largest integrated public-sector health care system in the United States. METHODS: The study examined all outpatient visits to VA clinics between October 1996 and March 1998, a time during which VA policy promoted a shift to a primary care model. For veterans with a primary diagnosis of a mental or substance use disorder who made any visit to a VA psychiatric, primary care, or specialty medical clinic, we compared the locus of care and case mix as well as changes in treatment patterns during the study period. RESULTS: Of 437,035 veterans treated for a mental disorder during the final six months of the study period, only 7 percent were seen for their mental disorders exclusively in primary care and specialty medical clinics. Compared with veterans with mental disorders treated in specialty mental health clinics, those treated in medical clinics had less serious psychiatric diagnoses and made fewer visits. While there was a substantial shift of care from specialty to primary care during the study period, no comparable change in the distribution of care between medical and mental health settings was found. CONCLUSIONS: Treatment patterns in VA clinics differ markedly from those in the private sector. Research is needed to determine whether and how staffing models developed in HMOs and community samples should be extended to these public-sector settings.     

Correlates of mental health service use intensity in the National Comorbidity Survey and National Comorbidity Survey Replication

OBJECTIVE: This study explored sociodemographic and mental health correlates of intensity of mental health care use in two large-scale surveys, aiming to discover the set of correlates with the greatest predictive capacity. METHODS: Data were examined from persons aged 15 to 54 in two nationally representative U.S. household surveys: the National Comorbidity Survey (NCS) (N=5,877), which gathered information from 1990 to 1992, and the NCS Replication (N=4,320), which gathered information from 2001 to 2003. Outcome variables were the number of mental health care visits in the past year to mental health providers, social service providers, and medical providers. This study implemented state-of-the-art statistical methods designed for modeling such outcomes as treatment intensity-that is, visit counts. RESULTS: Across provider types, significant univariate associations were found for intensity of mental health care use based on access variables (for example, employment and health insurance) and two need variables-psychiatric diagnoses and psychiatric disability. Demographic variables and treatment need variables were not consistent service use correlates. Multivariate regression accounting for excessive zero values demonstrated that after the analyses controlled for sociodemographic and access variables, mental disorders (mood, anxiety, and substance use disorders) and psychiatric disability added incrementally to variance in visit counts for mental health care. However, when mental health service use was dichotomized (any use versus no use) demographic and access variables, as well as psychiatric disorders, emerged as correlates. In both sets of analyses, different patterns of psychiatric disorder and disability were associated with provider service use. CONCLUSIONS: These findings extend research on correlates of mental health care use, addressing intensity of use, suggesting that sociodemographic factors and presence of a psychiatric disorder and associated disability drive the initial use of services, whereas presence of a psychiatric disorder and associated disability are associated with continued service use.     

Minimizing adverse effects on patients of involuntary relocation from long-stay wards to community residences

OBJECTIVES: This study examined the incidence of, and variables associated with, relocation trauma among 85 patients who moved from long-stay psychiatric wards to community care units as part of a hospital closure in Melbourne, Australia. METHODS: Some participants moved directly from wards and some moved first to transitional units on the hospital grounds. Preparation for the transition, such as visits to the community care unit before the move, was documented, and severity of symptoms, aggressive behaviors, and preferences for living environments one month before and one month after the move were compared. Relocation trauma was measured one month after the move. After significant factors associated with trauma were determined, additional tests further discriminated these factors. RESULTS: Although 66 percent of participants were happy with community care units one month after the move, 18 percent preferred hospital living. Of 81 participants who had data on relocation trauma, 20, or 25 percent, met relocation trauma criteria. Preparation in a transitional unit reduced the likelihood of trauma, as did making six or more premove visits to the new facility and having a preparation period of more than 16 weeks. When preparation in a transitional unit, number of premove visits, and duration of preparation were considered together, only the number of premove visits and duration of preparation remained significantly associated with relocation trauma. CONCLUSIONS: Adverse effects of relocation on long-stay psychiatric patients may be minimized by the preparation of patients over a period of four months or more, with inclusion of six or more visits to the new facility. Moving via a transitional environment is not essential.     

Mental Health Telephone Triage: Managing Psychiatric Crisis and Emergency

PURPOSE: The study aims to identify and articulate how mental health telephone triage (MHTT) clinicians manage psychiatric crisis and emergency via the telephone. DESIGN AND METHODS: An observational design was employed in the study. Wireless headsets were used to observe 197 occasions of MHTT. FINDINGS: Clinicians use a range of practical strategies, therapeutic skills, and psychosocial interventions to manage psychiatric crises and emergencies via the telephone. PRACTICE IMPLICATIONS: The evidence base for managing psychiatric crisis/emergency in MHTT is minimal. These findings contribute to the MHTT knowledge base and provide evidence‐based strategies for high‐quality emergency mental health care.
