Psychiatric inpatient,outpatient, and medication utilization and costs among privately insured youths, 1997-2000

OBJECTIVE: The study examined trends in use of inpatient and outpatient mental health services, including pharmacotherapy, among privately insured children and adolescents from 1997 to 2000. METHOD: Data from a national database of more than 1.7 million privately insured individuals were used in an analysis of inpatient, outpatient, and pharmacy claims of users of mental health care age 17 years and younger (approximately 20,000 patients per year). Annual utilization rates and adjusted costs for services and dispensed psychotropic medications were calculated. Results from 1997 and 2000 were compared across diagnostic and age categories. RESULTS: The proportion of youths with an inpatient psychiatric admission decreased by 23.7% from 1997 to 2000, and annual inpatient and outpatient costs decreased by 1,216 US dollars (18.4%) and 157 US dollars (14.4%), respectively. Decreases were driven by a reduction in inpatient days (20.0%) and by a combination of a reduction in outpatient visits (11.3%) and declining payments per outpatient visit (6.1%). Payment trends across diagnoses varied considerably, with the largest reductions seen in treatment of depression, hyperactivity, adjustment disorders, and anxiety disorders. Over the same period, the proportion of youths receiving medication increased by 4.9%, and mean annual medication-related costs per outpatient increased by 41 US dollars (12.1%). CONCLUSIONS: Reductions in inpatient and outpatient mental health service intensity and reimbursements documented in previous research continued through the late 1990s. Declines were accompanied by concurrent increases in the use of and costs associated with psychotropic medications, particularly for youths with mood and anxiety disorders. These results document a shift toward medication-based outpatient treatment modalities.     

Mental illness and use of home care nationally in the U.S. Department of Veterans Affairs.

OBJECTIVE: To determine whether patients with mental health diagnoses are more likely to utilize home-based primary care (HBPC), and to identify characteristics associated with HBPC admission among elderly and nonelderly veterans, specifically. METHODS: Patients receiving treatment during fiscal year (FY) 2003 and having no evidence of home care utilization during FY2002 were followed through FY2005 using administrative claims data of the Veterans Health Administration of the U.S. Department of Veterans Affairs (VA). Participants were 4,411,677 VA patients with no prior HBPC use. Cox proportional hazard models were developed to identify correlates of HBPC use. RESULTS: Of VA patients with no prior use of HBPC, 24.2% received a mental health diagnosis, of whom 1.5% eventually used HBPC. Two in five new HBPC admissions were diagnosed with mental illness. Patients diagnosed with dementia were 66% more likely to be admitted. Patients diagnosed with nonschizophrenia psychoses (hazard ratio [HR]: 1.30), miscellaneous affective disorders (HR: 1.22), and schizophrenia (HR: 1.21) had the next highest probabilities. Risk of admission was highest for > or = 3 outpatient medical visits (HR: 2.61), followed by any inpatient medical/surgical days (HR: 1.79) or outpatient mental health visits (HR: 1.30). Elderly patients with any inpatient mental health days were less likely to be admitted; younger patients with nursing home use, community residential care, and mental health intensive care management were more likely to be admitted. CONCLUSION: Given that mental illness is independently associated with the likelihood of admission, it is critical that providers develop the skills and resources necessary to meet the psychiatric needs of home care recipients.     

Racial disparities during admission to an academic psychiatric hospital in a large urban area

Multiple studies confirm that African Americans are less likely than non-Hispanic whites to receive needed mental health services. Research has consistently shown that African Americans are under-represented in outpatient mental health treatment settings and are over-represented in inpatient psychiatric settings. Further, African Americans are more likely to receive a diagnosis of schizophrenia and are less likely receive an affective disorder diagnosis during inpatient psychiatric hospitalization compared to non-Hispanic white patients, pointing to a need for examining factors contributing to mental health disparities. Using Andersen's Behavioral Model of Health Service Use, this study examined predisposing, enabling and need factors differentially associated with health service utilization among African American and non-Hispanic white patients (n = 5183) during psychiatric admission. We conducted univariate and multivariate logistic regression analyses to examine both main effects and interactions. In the multivariate model, African American race at admission was predicted by multiple factors including younger age, female gender, multiple psychiatric hospitalizations, elevated positive and negative symptoms of psychosis, a diagnosis of schizophrenia and substance use, as well as having housing and commercial insurance. Additionally, screening positive for cannabis use at intake was found to moderate the relationship between being female and African American. Our study findings highlight the importance of examining mental health disparities using a conceptual framework developed for vulnerable populations (such as racial minorities and patients with co-occurring substance use).     

Older Adult Patients with Both Psychiatric and Substance Abuse Disorders: Prevalence and Health Service Use

The prevalence and service use among older adults with concurrent psychiatric and substance abuse disorders (the dually diagnosed) was examined in a cross-sectional survey of a representative national sample of Department of Veterans Affairs mental health program patients (N = 91,752). Rates of dual diagnosis declined significantly (P = 0.001) as the age of the respondents increased (26.7% of patients < 65 years; 6.9% of patients 65 years). Dually diagnosed older adult patients had longer inpatient stays for substance abuse and more outpatient substance abuse visits than did non-dually diagnosed elderly patients, and more outpatient general psychiatric visits than all the contrast groups. Dual diagnosis appears less common among older compared to younger patients, although their heavy use of certain (particularly, outpatient psychiatric) services suggests that should more dually diagnosed patients survive to old age their consumption of some forms of mental health care is likely to be high.     

The effect of comorbid anxiety and depressive disorders on health care utilization and costs among adolescents with asthma

OBJECTIVE: To assess whether youth with asthma and comorbid anxiety and depressive disorders have higher health care utilization and costs than youth with asthma alone. METHODS: A telephone survey was conducted among 767 adolescents (aged 11 to 17 years) with asthma. Diagnostic and Statistical Manual-4th Version (DSM-IV) anxiety and depressive disorders were assessed via the Diagnostic Interview Schedule for Children. Health care utilization and costs in the 12 months pre- and 6 months post-interview were obtained from computerized health plan records. Multivariate analyses were used to determine the impact of comorbid depression and anxiety on medical utilization and costs. RESULTS: Unadjusted analyses showed that compared to youth with asthma alone, youth with comorbid anxiety/depressive disorders had more primary care visits, emergency department visits, outpatient mental health specialty visits, other outpatient visits and pharmacy fills. After controlling for asthma severity and covariates, total health care costs were approximately 51% higher for youth with depression with or without an anxiety disorder but not for youth with an anxiety disorder alone. Most of the increase in health care costs was attributable to nonasthma and non-mental health-related increases in primary care and laboratory/radiology expenditures. CONCLUSIONS: Youth with asthma and comorbid depressive disorders have significantly higher health care utilization and costs. Most of these costs are due to increases in non-mental health and nonasthma expenses. Further study is warranted to evaluate whether improved mental health treatment and resulting increases in mental health costs would be balanced by savings in medical costs.     

Health care utilization by older patients with coexisting dementia and depression

OBJECTIVE: Few studies have examined the course of coexisting dementia and depression. The purpose of this study was to compare elderly patients who had coexisting dementia and depression with elderly patients who had either disorder alone in terms of their utilization of inpatient and outpatient services. METHOD: The study group included 7,115 veterans aged 60 years or older who had been discharged from Department of Veterans Affairs inpatient units in 1992 with diagnoses of major depression, dementia, or both. Outcome measures were analyzed for a 2-year period following the index hospitalization for each diagnostic study group. RESULTS: Patients with coexisting dementia and depression had significantly more psychiatric inpatient days than the other two study groups and more medical inpatient days and nursing home readmissions than patients with depression alone. Patients with coexisting dementia and depression had significantly more total inpatient days than the other two groups. Notably, patients with coexisting dementia and depression did not utilize more outpatient resources than the other study groups; in fact, they had significantly fewer medical, psychiatric, and total visits than patients with depression alone. CONCLUSIONS: The findings suggest that patients with coexisting dementia and depression are high utilizers of inpatient services, with a course of illness that may resemble dementia in terms of nursing home and inpatient medical care utilization and depression in terms of inpatient psychiatric care utilization; however, these patients utilized significantly fewer outpatient resources than the group with depression alone. Aggressive outpatient treatment approaches might reduce utilization of inpatient care for patients with coexisting depression and dementia.     

Psychiatric disorder,impairment, and service use in rural African American and white youth

BACKGROUND: The Caring for Children in the Community Study examined the prevalence of DSM-IV psychiatric disorders and correlates of mental health service use in rural African American and white youth. METHODS: Four thousand five hundred youth aged 9 to 17 years from 4 North Carolina counties were randomly selected from school databases. Parents completed telephone questionnaires about their children's behavior problems. A second-stage sample of 1302 was identified for recruitment into the interview phase of the study, and 920 (70.7%) of these were successfully interviewed at home using the Child and Adolescent Psychiatric Assessment and related measures of service use. RESULTS: Weighted back to general population estimates, 21.1% of youth had 1 or more DSM-IV psychiatric disorders in the past 3 months. Prevalence was similar in African American (20.5%) and white (21.9%) youth. The only ethnic difference was an excess of depressive disorders in white youth (4.6% vs 1.4%). Thirteen percent of participants (36.0% of those with a diagnosis) received mental health care in the past 3 months. White youth were more likely than African American youth to use specialty mental health services (6.1% vs 3.2%), but services provided by schools showed very little ethnic disparity (8.6% vs 9.2%). The effect of children's symptoms on their parents was the strongest correlate of specialty mental health care. CONCLUSIONS: In this rural sample, African American and white youth were equally likely to have psychiatric disorders, but African Americans were less likely to use specialty mental health services. School services provided care to the largest number of youths of both ethnic groups.     

Interpersonal trauma and posttraumatic stress disorder in patients with severe mental illness: demographic, clinical, and health correlates

This study's purpose was to evaluate the prevalence and correlates of posttraumatic stress disorder (PTSD) in persons with severe mental illness. Standardized assessments of interpersonal trauma and PTSD were conducted in 782 patients with severe mental illness receiving services in one of five inpatient and outpatient treatment settings. Analyses examined the prevalence of PTSD and the demographic, clinical, and health correlates of PTSD diagnosis. The overall rate of current PTSD in the sample was 34.8 percent. For demographic characteristics, the prevalence of PTSD was higher in patients who were younger, white, homeless, and unemployed. For clinical and health variables, PTSD was more common in patients with major mood disorders (compared to schizophrenia or schizoaffective disorders), alcohol use disorder, more recent psychiatric hospitalizations, more health problems, more visits to doctors for health problems, and more nonpsychiatric hospitalizations over the past year. The results support prior research documenting the high rates of PTSD in patients with severe mental illness and suggest that PTSD may contribute to substance abuse, psychiatric and medical comorbidity, and psychiatric and health service utilization.     

Considering context, place and culture: the National Latino and Asian American Study

This paper provides a rationale for, and overview of, procedures used to develop the National Latino and Asian American Study (NLAAS). The NLAAS is nationally representative community household survey that estimates the prevalence of mental disorders and rates of mental health service utilization by Latinos and Asian Americans in the US. The central aims of the NLAAS are to: 1) describe the lifetime and 12-month prevalence of psychiatric disorders and the rates of mental health services use for Latino and Asian American populations using nationwide representative samples of Latinos and Asian Americans, 2) assess the associations among social position, environmental context, and psychosocial factors with the prevalence of psychiatric disorders and utilization rates of mental health services, and 3) compare the lifetime and 12-month prevalence of psychiatric disorders, and utilization of mental health services of Latinos and Asian Americans with national representative samples of non-Latino whites (from the National Comorbidity Study-Replication) (NCS-R) and African Americans (from the National Survey of American Life) (NSAL). This paper presents new concepts and methods utilized in the development of the NLAAS to capture and investigate ethnic, cultural and environmental considerations that are often ignored in mental health research.     

Mental disorders and quality of diabetes care in the veterans health administration

OBJECTIVE: The population of persons with mental disorders is potentially vulnerable to poor quality of medical care. This study examined the relationship between mental disorders and quality of diabetes care in a national sample of veterans. METHOD: Chart-abstracted quality data were merged with outpatient and inpatient administrative database records for a sample of veterans with diabetes who had at least three outpatient visits in the previous year (N=38,020). Mental health diagnoses were identified by use of the administrative data. Quality of diabetes care was assessed with five indicators by chart documentation: annual foot inspection, pedal pulses examination, foot sensory examination, retina examination, and glycated hemoglobin determination. RESULTS: Approximately a quarter of the sample had a diagnosed mental disorder (23.7% with psychiatric disorder only, 1.3% with substance use disorder only, and 2.6% with a dual diagnosis). Overall rates of receipt for the indicators were higher than national benchmarks for all patient subgroups, ranging from 70.8% for retina examination to 95.0% for foot inspection. Rates for both retina examination and foot sensory examination differed significantly by mental health status, mainly because of lower rates among those with a substance use disorder. The associations remained significant in multivariate generalized estimating equation analyses that controlled for demographic characteristics, health status, use of medical services, and hospital-level characteristics. CONCLUSIONS: Rates for secondary prevention of diabetes were remarkably high at Department of Veterans Affairs medical centers, although patients with mental disorders (particularly substance use disorders) were somewhat less likely to receive some of the recommended interventions.     

Somatization increases medical utilization and costs independent of psychiatric and medical comorbidity

CONTEXT: Somatoform disorders are an important determinant of medical care utilization, but their independent effect on utilization is difficult to determine because somatizing patients frequently have psychiatric and medical comorbidity. OBJECTIVES: To assess the extent of the overlap of somatization with other psychiatric disorders; to compare the medical utilization of somatizing and nonsomatizing patients; and to determine the independent contribution of somatization alone to utilization. DESIGN: Patients were surveyed with self-report questionnaires assessing somatization and psychiatric disorder. Medical care utilization was obtained from automated encounter data for the year preceding the index visit. Medical morbidity was indexed with a computerized medical record audit. SETTING: Two hospital-affiliated primary care practices. PARTICIPANTS: Consecutive adults making scheduled visits to their primary care physicians on randomly chosen days. In all, 2668 questionnaires were distributed, and 1914 (71.7%) were returned. Of these, 1546 (80.8%) contained complete data and met eligibility criteria. MAIN OUTCOME MEASURES: Medical care utilization and costs within our hospital system in the preceding 12 months. RESULTS: Two hundred ninety-nine patients (20.5%) received a provisional diagnosis of somatization; 42.3% of these patients had no comorbid depressive or anxiety disorder. Somatizing patients, when compared with nonsomatizing patients, had more primary care visits (mean [SE], 4.90 [0.32] vs 3.43 [0.11]; P<.001); more specialty visits (mean [SE], 8.13 [0.55] vs 4.90 [0.21]; P<.001); more emergency department visits (mean [SE], 1.29 [0.15] vs 0.52 [0.036]; P<.001); more hospital admissions (mean [SE], 0.32 [0.051] vs 0.13 [0.014]; P<.001); higher inpatient costs (mean [SE], USD 3146 [USD 380] vs USD 991 [USD 193]; P<.001); and higher outpatient costs (mean [SE], USD 3208 [USD 180] vs USD 1771 [USD 91]; P<.001). When these results were adjusted for the presence of comorbid anxiety and depressive disorders, major medical morbidity, and sociodemographic characteristics, patients with somatoform disorder still had more primary care visits (P = .04), more specialist visits (P = .002), more emergency department visits (P<.001), more hospital admissions (P<.001), more ambulatory procedures (P<.001), higher inpatient costs (P<.001), and higher outpatient costs (P<.001). When these findings are extrapolated to the national level, an estimated USD 256 billion a year in medical care costs are attributable to the incremental effect of somatization alone. CONCLUSIONS: Patients with somatization had approximately twice the outpatient and inpatient medical care utilization and twice the annual medical care costs of nonsomatizing patients. Adjusting the findings for the presence of psychiatric and medical comorbidity had relatively little effect on this association.     

Inpatient and outpatient psychiatric services: substitutes or complements?

Patients at risk for psychiatric hospitalization make only limited use of outpatient services, although clinical research has demonstrated that outpatient treatments and home care can be as effective as inpatient psychiatric treatment in treating certain mental health problems. The substitution of ambulatory services for inpatient care has in part been limited because insurers have restricted outpatient mental health benefits to control utilization. The authors critically review evidence from the economic and clinical literatures to determine the extent to which outpatient psychiatric treatment substitutes or complements inpatient treatment. To encourage clinically effective substitution of outpatient for inpatient services, further research is needed to identify the patient populations for whom substitution is possible and the treatment and environmental conditions in which it is most likely to be successful.     

Patterns of health care costs associated with depression and substance abuse in a national sample

OBJECTIVE: The associations between self-reported depressive and substance use disorders and estimated health care costs were examined in a representative national sample. METHODS: Data were from the 1994 National Health Interview Survey (N=77,183). Respondents who reported depressive symptoms or major depression (depressive syndromes) or a substance abuse disorder in the past year were compared with respondents who did not report these conditions. The mean number of inpatient days and outpatient visits in both the general medical and the specialty mental health settings were determined, and costs per individual were calculated based on mean costs of such care in each respondent's geographic region. Multivariate models were constructed to calculate mean costs, controlling for demographic variables, insurance coverage, and physical health status. RESULTS: Individuals with self-reported depressive syndromes or substance abuse had mean health care costs that were $1,766 higher than costs for individuals without these conditions. Depressive syndromes were associated with increases in both inpatient and outpatient costs. However, substance abuse was almost exclusively associated with increased inpatient expenditures rather than outpatient costs. The magnitude of increased costs associated with mental disorders was substantially larger for patients in fee-for-service plans than for those in health maintenance organizations. Only 14.3 percent of visits made by individuals reporting depressive syndromes or substance abuse were made to specialty health providers (psychiatrists, psychologists, and social workers). CONCLUSIONS: Health care costs of people with self-reported mental illness varied significantly across diagnoses and systems of care. It is crucial that researchers estimating increased costs associated with mental illness account for both diagnostic and system factors that can influence the estimates.     

Use of psychiatric and medical health care by veterans with severe mental illness

Risk behaviors and health care use among 396 initially hospitalized veterans with severe mental illnesses were examined. Health care use was abstracted from Veterans Affairs databases (March 1998 to June 2000) for one year after hospital discharge. Lifetime intravenous drug use was related to increased use of outpatient services, and current alcohol use was related to decreased health care use. Patients with posttraumatic stress disorder had greater use of medical outpatient services than patients with schizophrenia-spectrum disorders, although they had longer hospital stays. These results highlight that veterans with severe mental illness receive more treatment in medical than psychiatric health clinics.     

Health, healthcare utilization and psychiatric disorder in people with intellectual disability in Taiwan

Objectives The aims of the present study were to examine health characteristics and healthcare utilization in relation to people with intellectual disability (ID) having psychiatric disorders in Taiwan. Methods A cross-sectional study was employed; study subjects were recruited from the National Disability Registration Database. Taiwan, stratified by administrative geographical area for the study. Statistical analysis of 1026 carers for people with ID was made to examine the health status and healthcare utilization of individuals with ID having psychiatric disorders. Results Approximately 12.1% of people with ID had psychiatric disorders. These individuals were more likely to be poorer in health condition and consuming more medical services (in the outpatient, inpatient and emergency care areas), than those individuals without psychiatric disorders. These individuals with psychiatric disorders were also taking medicines regularly at a far greater percentage than did those without psychiatric disorders. Conclusions Given the high prevalence of psychiatric disorders among individuals with ID, the healthcare system should take further steps to develop an appropriate health status monitoring system and community-based and easily accessible mental health services for them.     

Treatment, care, and rehabilitation of the chronic mentally ill in Sweden

For the last 20 years in Sweden, there has been a trend to integrate psychiatry with general medical services. However, mental hospitals remain the dominant resource for psychiatric care, with psychiatric units in general hospitals providing less than 20 percent of psychiatric hospital beds. The imbalance between the high number of inpatient facilities and the low rate of outpatient visits is beginning to be corrected by the newly introduced sector system, which allocates mental health care resources among geographic zones. The sector system has been criticized, however, because some believe it is fostering disintegration of existing resources and loss of research opportunities. A general spirit of improvement exists, but at the same time the public budget is being squeezed.     

Competition or catastrophe: Insurance for psychiatric care

On January 5, 1981, Blue Cross/Blue Shield, Federal Employees Program (FEP) of the Federal Employees Health Benefits Program (FEHBP) reduced its psychiatric benefits by raising the co-payment for outpatient mental health treatment from 20 to 30 percent. This was only a first step in a major reduction which took place on January 1, 1982. On that date an annual limit of 50 outpatient visits and 60 inpatient days was introduced. FEP had been widely recognized as the broadest and best insurance coverage for mental disorders in the United States. This series of reductions may be part of an overall trend to reduce mental health benefit programs under insurance systems. This paper will review these changes in a context of ongoing problems for mental health coverage under insurance and various approaches to paying for psychiatric care through third party payments. These approaches include a market or “competitive” approach, a traditional insurance or “catastrophic” approach, and a public health approach.     

Aging and schizophrenia: current health services research and recommendations

Little is known about the functioning and health care use of older patients with schizophrenia. Understanding the use patterns of older patients with schizophrenia, a rapidly growing population, will inform health care planners and policy makers who make decisions about resource allocation and program development. The results are presented from a large-scale study to examine the relationship between age and the use of health services and level of functioning in patients with schizophrenia. Older adults with schizophrenia experienced fewer psychiatric hospitalizations but, once hospitalized, had longer inpatient stays. In contrast, older patients had fewer outpatient psychiatric visits and more medical outpatient visits and medical hospitalizations than younger individuals. The relatively lower use of outpatient psychiatric care by older patients with schizophrenia suggests that there may be barriers to accessing these services. When older patients are hospitalized for psychiatric reasons, their stays are longer. The implications of these findings are discussed.     

How do HMOs reduce outpatient mental health care costs?

OBJECTIVE: Because previous studies of differences in utilization of mental health care services have had important limitations, it is not clear if their findings that health maintenance organization (HMO) outpatient mental health care costs less than fee-for-service care are due to less access, less intensive care per user, or selective enrollment of healthier people by HMOs. Therefore, the authors used data from the National Institute of Mental Health Epidemiologic Catchment Area (ECA) study to examine differences in the prevalence of psychiatric disorder and differences in the use of outpatient mental health services for adults enrolled in HMO or fee-for-service health insurance plans. METHOD: The subjects were an ECA community sample obtained from East Los Angeles and West Los Angeles. This sample included a large number of Hispanic subjects. The subjects were categorized according to their responses to a 5-item battery on insurance as Medicare enrolles, members of private fee-for-service plans, Medicaid enrollees, members of an HMO, and uninsured. The presence or absence of psychiatric disorders was determined by using the NIMH Diagnostic Interview Schedule. Both users and nonusers of mental health services were studied. RESULTS: The HMO and fee-for-service plans had similar prevalence of psychiatric disorder and similar access to specialty mental health care. However, HMO enrollees had significantly fewer visits per user to providers of specialty care. CONCLUSIONS: The most likely explanation for lower mental health care costs in HMOs is a less intensive style of care for a comparably sick population.
