Barriers to the care of persons with dual diagnoses: organizational and financing issues

Among the frustrations of managing the dual disorders of chronic mental illness and alcohol and drug abuse is the fact that knowing what to do (by way of special programming) is insufficient to address the problem. The system problems are at least as intractable as the chronic illnesses themselves. Organizing and financing care of patients with comorbities is complicated. At issue are the ways in which we administer mental health and alcohol and drug treatment as well as finance that care. Separate administrative divisions and funding pools, while appropriate for political expediency, visibility, and administrative efficiency, have compounded the problems inherent in serving persons with multiple disabilities. Arbitrary service divisions and categorical boundaries at the State level prevent local governments and programs from organizing joint projects or creatively managing patients across service boundaries. When patients cannot adapt to the way services are organized, we risk reinforcing their overutilization of inpatient and emergency services, which are ineffective mechanisms for delivering the care these patients need. This article reviews the barriers in organization and financing of care (categoric and third party financing, including the special problem of diagnosis-related groups limitations) and proposes strategies to enhance the delivery of appropriate treatment.

Use of minor tranquilizers and antidepressant medications by depressed outpatients: results from the medical outcomes study

OBJECTIVE

The purpose of this study was to compare use of minor tranquilizers and antidepressant medications by depressed outpatients across different treatment settings.

METHOD

The study subjects were 634 patients with current depressive disorder or depressive symptoms who visited general medical clinicians, psychiatrists, psychologists, or other therapists. Data on use of medication in different types of clinical practices with different types of payment plans were gathered from structured interviews by study clinicians and from surveys of patients.

RESULTS

Of the depressed patients, 23% had recently used an antidepressant medication and 30% had used a minor tranquilizer. The level of use was similar for different types of depression. Patients of psychiatrists were the most likely to use medications. In the practices of physicians, but not nonphysicians, the more severely distressed patients were more likely to use antidepressant medications. Of the patients taking an antidepressant medication, 39% used an inappropriately low dose. Patients in prepaid health care plans were twice as likely as those in fee-for-service care to use minor tranquilizers.

CONCLUSIONS

Less than one-third of the depressed outpatients used antidepressant medications, and the probability of use was similar for major depression and other types of depression for which efficacy is less well established. Use of antidepressant medications among patients of nonphysicians was unrelated to the level of psychological sickness, suggesting the need for more cooperation among provider groups. Minor tranquilizers were used more often than antidepressants, particularly among patients in prepaid plans, despite controversy over their efficacy.

Long-term Effectiveness and Cost of a Systematic Care Program for Bipolar Disorder

CONTEXT

Despite the availability of efficacious treatments, the long-term course of bipolar disorder is often unfavorable.

OBJECTIVE

To test the effectiveness of a multicomponent intervention program to improve the quality of care and long-term outcomes for persons with bipolar disorder.

DESIGN

Randomized controlled trial with allocation concealment and blinded outcome assessment.

SETTING

Mental health clinics of a group-model prepaid health plan.

PATIENTS

Of 785 patients in treatment for bipolar disorder who were invited to participate, 509 attended an evaluation appointment, 450 were found eligible to participate, and 441 enrolled in the trial.

INTERVENTIONS

Participants were randomly assigned to a multicomponent intervention program or to continued care as usual. Three nurse care managers provided a 2-year systematic intervention program, including the following: a structured group psychoeducational program, monthly telephone monitoring of mood symptoms and medication adherence, feedback to treating mental health providers, facilitation of appropriate follow-up care, and as-needed outreach and crisis intervention.

MAIN OUTCOME MEASURES

In-person blinded research interviews every 3 months assessed mood symptoms using the Longitudinal Interval Follow-up Examination. Health plan administrative records were used to assess the use and cost of mental health services.

RESULTS

Intent-to-treat analyses demonstrated that the intervention significantly reduced the mean level of mania symptoms (z = 2.09, P = .04) and the time with significant mania symptoms (19.2 vs 24.7 weeks; F(1) = 6.0, P = .01). There was no significant intervention effect on mean level of depressive symptoms (z = 0.19, P = .85) or time with significant depressive symptoms (47.6 vs 50.7 weeks; F(1) = 0.56, P = .45). Benefits of the intervention were found only in a subgroup of 343 persons with clinically significant mood symptoms at the baseline assessment. The incremental cost (adjusted) of the intervention was 1251 dollars (95% confidence interval, 55-2446 dollars), including approximately 800 dollars for the intervention program services and an approximate 500 dollars increase in the costs of other mental health services.

CONCLUSIONS

Population-based systematic care programs can significantly reduce the frequency and severity of mania in bipolar disorder, and cost increases are modest considering the clinical gains. The incorporation of more specific cognitive and behavioral content or more effective medication regimens may be necessary to significantly reduce the symptoms of depression.

Health care reform for Americans with severe mental illnesses: report of the National Advisory Mental Health Council

This report was produced in response to a request by the Senate Committee on Appropriations that the National Advisory Mental Health Council prepare and submit a report on the cost of insurance coverage of medical treatment for severe mental illness commensurate with the coverage of other illnesses and an assessment of the efficacy of treatment of severe mental disorders. About 5 million Americans (2.8% of the adult population) experience severe mental disorders in a 1-year period. Treating these disorders now costs the nation an estimated $20 billion a year (with an additional $7 billion a year in nursing home costs). These costs represent 4% of total U.S. direct health care costs. When the social costs are also included, severe mental disorders exact an annual financial toll of $74 billion. This total accounts for the dollar costs of shortened lives and lost productivity, as well as the costs incurred in the criminal justice and social service systems. However, it cannot begin to account in human terms for the enormous emotional cost and pain borne by Americans with severe mental illness and by their families. Many myths and misunderstandings contribute to the stigmatization of persons with mental illness and to their often limited access to needed services. For example, millions of Americans and many policy makers are unaware that the efficacy of an extensive array of treatments for specific mental disorders has been systematically tested in controlled clinical trials; these studies demonstrate that mental disorders can now be diagnosed and treated as precisely and effectively as are other disorders in medicine. The existence of effective treatments is only relevant to those who can obtain them. Far too many Americans with severe mental illness and their families find that appropriate treatment is inaccessible because they lack any insurance coverage or the coverage they have for mental illness is inequitable and inadequate. For example, private health insurance coverage for mental disorders is often limited to 30-60 inpatient days per year, compared with 120 days or unlimited days for physical illnesses. Similarly, the Medicare program requires 50% copayment for outpatient care of mental disorders, compared with 20% copayment for other medical outpatient treatment. These inequities in both the public and private sectors can and should be overcome.(ABSTRACT TRUNCATED AT 400 WORDS)

Mental disorders and access to medical care in the United States

OBJECTIVE

The authors examined the barriers to receipt of medical services among people reporting mental disorders in a representative sample of U.S. adults.

METHOD

The sample was drawn from adults who responded to the 1994 National Health Interview Survey (N=77,183). The authors studied the association between report of a mental disorder and 1) access to health insurance and a primary provider, and 2) actual receipt of medical care. Multivariate techniques were used to model problems with access as a function of mental disorders, controlling for demographic, insurance, and health variables.

RESULTS

While people who reported mental disorders showed no difference from those without mental disorders in likelihood of being uninsured or of having a primary care provider, they were twice as likely to report having been denied insurance because of a preexisting condition or having stayed in their job for fear of losing their health benefits. Among respondents with insurance, those who reported mental illness were no less likely to have a primary care provider but were about two times more likely to report having delayed seeking needed medical care because of cost or having been unable to obtain needed medical care.

CONCLUSIONS

People who reported mental disorders experienced significant barriers to receipt of medical care. Efforts to measure and improve access to health care for this population may need to go beyond simply providing insurance benefits or access to general medical providers.

Insurance expenditures on bipolar disorder: clinical and parity implications

OBJECTIVE

This study assessed treatment rates and expenditures for behavioral health care by employers and behavioral health care patients in a large national database of employer-sponsored health insurance claims.

METHOD

Insurance claims from 1996 from approximately 1.66 million individuals were examined. Average annual charges per person and payments for behavioral health care were calculated along with patient out-of-pocket expenses and inpatient hospital admission rates. Behavioral health care expenditures for bipolar disorder were compared to expenditures for other behavioral health care diagnoses in these same insurance plans.

RESULTS

A total of 7.5% of all covered individuals filed a behavioral health care claim. Of those, 3.0% were identified as having bipolar disorder, but they accounted for 12.4% of total plan expenditures. Patients with bipolar disorder incurred annual out-of-pocket expenses of $568, more than double the $232 out-of-pocket expenses incurred by all claimants. The inpatient hospital admission rate for patients with bipolar disorder was also higher (39.1%) compared to 4.5% for all other behavioral health care claimants. Furthermore, annual insurance payments were higher for covered medical services for individuals with bipolar disorder than for patients with other behavioral health care diagnoses.

CONCLUSIONS

Bipolar disorder is the most expensive behavioral health care diagnosis, both for patients with bipolar disorder and for their insurance plans. For every behavioral health care dollar spent on outpatient care for patients with bipolar disorder, $1.80 is spent on inpatient care, suggesting that better prevention management could decrease the financial burden of bipolar disorder.

Health care utilization and costs among privately insured patients with bipolar I disorder

OBJECTIVE

This study examined health care resource utilization and direct health care costs among patients diagnosed with bipolar I disorder in a privately insured population.

METHODS

Health care claims data for 2883 patients with a primary diagnosis of bipolar disorder were compared over a 1-year period (1997) with claims data for 2883 randomly selected, age- and sex-matched, non-bipolar patients, all covered under the same large private insurer in USA. Resource use (i.e. original and refill pharmaceutical dispensing, medical and procedural services received, inpatient hospitalization, outpatient services, physician visits and emergency room treatment) and their costs are described overall, as well as by bipolar disorder diagnosis (based on ICD-9 codes) and type of care (i.e. mental health versus non-mental health).

RESULTS

Bipolar patients utilized nearly three to four times the health care resources and incurred over four times greater costs per patient compared with the non-bipolar group during the 1-year period ($7663 versus $1962). Inpatient care (hospitalizations) accounted for the greatest disparity between groups, as it was the single-most costly resource in the bipolar group ($2779 versus $398). Patients with bipolar depression (among the single bipolar diagnostic categories of mixed, manic or depressed) incurred the highest health care costs. While mental health care cost was a significant component of total cost in the bipolar group, it accounted for only 22% of the total per-patient cost; in comparison, it accounted for only 6% of the total per-patient cost in the non-bipolar group.

CONCLUSION

Treatment of bipolar disorder, particularly inpatient care, is costly to patients and health insurers. Further study is needed to find ways to reduce the overall cost of managing these patients without jeopardizing patient care.

Evaluating psychotherapy

The authors analyze the possible need for a standing national group to evaluate the efficacy and safety of the psychotherapies. The current need is for a body whose function is more scientifically evaluative and less regulatory than the Food and Drug Administration because available psychotherapies are less specific in their beneficial effects and less dangerous than are drugs and because the practice of psychotherapy cannot be restricted entirely to the health professions. Even so, the authors believe the main criteria for discerning the boundaries between research and established practice are in principle at least as clear for psychotherapy as for other health interventions.

Medical costs attributed to depression among patients with a history of high medical expenses in a health maintenance organization

BACKGROUND

While previous studies have compared medical utilization between depressed and nondepressed patients, we conducted a study that focused specifically on patients who had a history of high medical expenditures.

METHODS

This study was designed to determine whether a positive screen for depression is predictive of continued high medical expenditures. Medical utilization data were obtained on 50,000 patients enrolled in the DeanCare health maintenance organization for 2 consecutive years. Consistent high utilizers were identified based on the medical utilization costs (paid by the health maintenance organization) for those 2 consecutive years, 1992 and 1993. A depression screen based on the Medical Outcomes Survey was mailed to 786 high utilizers. Their costs were determined for 1994. Regression analyses identified 1994 costs associated with depression, adjusting for age, sex, benefits package, and medical comorbidity.

RESULTS

Depressed high utilizers were more likely than nondepressed high utilizers to have higher medical costs in 1994. Among high utilizers, depressed patients' 1994 costs were significantly higher ($5764 vs $4227; P < .001), although expenditures for depressed and nondepressed high utilizers were similar for the previous 2 years. The total medical cost associated with depression in 1994, adjusted for age, sex, benefits package, and medical comorbidity, was $1498 per patient.

CONCLUSIONS

In the third year (1994), a positive Medical Outcomes Survey screen for depression in high utilizers was associated with $1498 in higher medical costs. The average actual amount spent on depression treatment accounted for only a small portion of total medical costs for depressed high utilizers in the third year.

The economic costs of schizophrenia. Implications for public policy

The direct and indirect costs associated with schizophrenia in Australia were calculated using the incidence approach and compared with similar costings of myocardial infarction in Australia and the United States. In Australia schizophrenia affects one-twelfth as many people as does myocardial infarction, yet costs half as much. This is because the stream of costs associated with each case of schizophrenia is six times the stream of costs associated with myocardial infarction. To illustrate the utility of this costing approach, the information was used to estimate the cost-benefit ratio likely to follow the introduction of social intervention strategies. The information also showed that Australian support for research in schizophrenia is inadequate when compared with that for myocardial infarction and quite out of proportion to the cost of schizophrenia to the community.

Some economics of mental health 'carve-outs'

We discuss the rationale for benefit carve-out contracts in general and for mental health and substance abuse in particular. We focus on the control of adverse selection as a principal explanation and find that this is consistent with the wide-spread use of sole-source contracting with periodic rebidding. We also find that some degree of risk sharing is common; we interpret this as a method of balancing cost-containment incentives with incentives to maintain access and quality on unmeasured dimensions.

Who gets hospitalized in a continuum of care?

OBJECTIVE

To compare children and adolescents hospitalized under a continuum of care with those hospitalized under traditional insurance coverage.

METHOD

With comprehensive data, logistic regressions were used to predict hospitalization and to identify its determinants.

RESULTS

As expected, the probability of being hospitalized was much higher under traditional care. In addition, the predictors of hospitalization differed by site. Accuracy of predictions was high.

CONCLUSIONS

Different kinds of children were hospitalized under a continuum of care than under a traditional insurance system. Hospitalizations under both systems were highly predictable.

Categorization of types of medical/psychiatry units based on level of acuity

Medical/psychiatry units can be categorized by the level of acuity of medical and psychiatric illness. Type I units are categorized as those that primarily provide psychiatric care with a low level of medical acuity. Type II units include general medicine or medical subspecialty units that are associated with a psychiatric liaison service and provide low levels of psychiatric care to those admitted to the general medical setting. Type III and Type IV units are characterized by a true departure from the current ward settings and care for patients who have concurrent and more severe medical and psychiatric problems in a unified setting. Both of these units require special physical changes in the ward structure, additional nurse training, and coordinated physician coverage to function effectively.

Outpatient psychotherapy in the United States, I: Volume, costs, and user characteristics

OBJECTIVE

This article provides an overview of the volume, composition, and costs of outpatient psychotherapy in the United States.

METHOD

Data were analyzed from the household section of the 1987 National Medical Expenditure Survey. The authors determined the volume and distribution of psychotherapy visits by provider specialty, setting, source of expenditure, and reason for visit. An examination was made of the demographic characteristics, health status, and mental health utilization profile of psychotherapy users.

RESULTS

In 1987, Americans made 79.5 million outpatient psychotherapy visits at a total cost of $4.2 billion. Most of these visits were to mental health specialists (more than 80%) and were reported to be for the treatment of mental health conditions (63.5%). However, psychotherapy was not provided in a substantial proportion of the visits to mental health specialists (21.1%) or the visits to treat mental conditions (29.8%). Separated and divorced persons, females, whites persons aged 35 to 49 years, and those with more than 15 years of education had a greater likelihood of using psychotherapy. Psychotherapy use was also greater among persons in poor general health and those reporting health-related functional impairments. General medical costs of psychotherapy users exceeded those of nonusers.

CONCLUSIONS

Psychotherapy accounts for approximately 8% of outpatient medical care costs. Users of psychotherapy appear to be more distressed than is commonly assumed: they report poorer general health, higher general medical costs, and more functional impairment than nonusers. Although mental health specialists commonly provide psychotherapy to treat mental disorders, all mental health care is not psychotherapy.

The impact of mental health insurance laws on state suicide rates

In the 1990s and early 2000s, a number of states passed laws requiring mental health benefits to be included in health insurance coverage. The variation in the characteristics and enactment date of the laws provides an opportunity to measure the impact of increasing access to mental health care on mental health outcomes, as evidenced by state suicide rates. In contrast with previous research, results show that when states enact laws requiring insurance coverage to include mental health benefits at parity with physical health benefits, the suicide rate decreases significantly by 5%. The findings are robust to a number of specifications and falsification tests.

Consultation-liaison psychiatry in western Europe. The European Consultation-Liaison Workgroup

Consultation-liaison psychiatry (C-L) services have developed throughout Europe, largely as a result of individual local initiative. Reviews by contributors from 14 countries reveal similarities in national approaches and in the problems caused by inadequate resources, lack of recognition from psychiatric colleagues, and difficulties in integrating C-L with comprehensive systems of psychiatric care, which are mainly oriented toward community care. National C-L organizations and a recently established European Workgroup have focused attention on the clinical importance of C-L and the need to define national and local policies for its clinical role, staffing, and other resources. There is considerable and increasing interest in European C-L research.

Utilization of health and mental health services in a large insured population

The authors analyzed 1975 data on the use of health and mental health services by the 2.3 million people covered by Michigan Blue Cross and Blue Shield. Only 4.6% of the covered population submitted hospital or physician claims for mental disorder; these people accounted for 7.3% of total hospital and physician charges for all health services in the covered population. According to the claims submitted, nonpsychiatric physicians saw almost half of all patients who were given a diagnosis of mental disorder, but psychiatrists accounted for the great bulk of mental health services and charges to these patients. High utilizers comprise a small proportion of all patients but account for a high proportion of charges for mental disorders and for all diagnoses.

The relationship between insurance coverage and psychiatric disorder in predicting use of mental health services

OBJECTIVE

This study investigated how insurance coverage for mental health services affects outpatient mental health service utilization among those with and among those without a DSM-III psychiatric diagnosis. The authors used a representative community sample to compare the regression effects of insurance coverage on utilization of mental health services among these subjects.

METHOD

Data are from the second wave of the Piedmont, North Carolina, site of the Epidemiologic Catchment Area project. These data contain DSM-III diagnostic measures derived from the National Institute of Mental Health Diagnostic Interview Schedule as well as measures of insurance coverage and utilization. Responses from 2,889 community residents were analyzed using both ordinary least squares and logistic regression.

RESULTS

In both models, insurance coverage was strongly associated with care among those with as well as among those without a psychiatric disorder. The association between coverage and the probability of care was strongest among those with a disorder.

CONCLUSIONS

The findings are not consistent with the claim that failing to provide insurance coverage will reduce discretionary but not necessary mental health care utilization. They provide evidence that failing to provide insurance coverage will reduce utilization as much or more among those with a psychiatric disorder as among those without. This result has important implications for health care reform.

Use of inpatient services by a national population: do benefits make a difference?

This study describes changes in the use of inpatient mental health services by children and adolescents under age 18. The data were insurance claims from the Blue Cross and Blue Shield Federal Employees Program. The study focused on a cut in inpatient benefits that occurred between 1978 and 1983. The rate of inpatient hospitalization dropped significantly, and the average number of days also decreased significantly from 45.8 to 27.0 days. This study is among the first to demonstrate that the rate and amount of inpatient care provided for children and adolescents is responsive to variations in benefit coverage.

Outpatient psychotherapy in the United States, II: Patterns of utilization

OBJECTIVE

The purpose of this article is to characterize the use of psychotherapy based on episode duration.

METHOD

Data were analyzed from the household section of the 1987 National Medical Expenditure Survey. The authors determined the demographic characteristics, provider and reason for visit distribution, mental and physical health status, and expenditures associated with very short-term (one to two sessions), short-term (three to 10 sessions), intermediate-term (11 to 20 sessions), and long-term (> 20 sessions) psychotherapy.

RESULTS

Long-term psychotherapy accounted for 15.7% of psychotherapy users and 62.9% of total psychotherapy expenditures. Age above 65 years, black race, and less than 12 years of education decreased the likelihood of receiving long-term psychotherapy. Whereas long-term psychotherapy episodes tended to be provided by the specialty sector (65.7%) for specific mental conditions (53.8%), very short-term episodes were predominantly provided by the general medical sector (72.2%) for general medical or unspecified conditions (68.3%). Psychotropic medication use and, to less extent, psychiatric hospitalization tended to be more common among longer- as opposed to shorter-term users.

CONCLUSIONS

Long-term and short-term psychotherapy tend to be provided by different health care professionals for the treatment of different types of health conditions. To help ensure the future of third-party payment for long-term psychotherapy, research is needed to better define the conditions under which long-term psychotherapy achieves benefits that equal or surpass those of other medical services or procedures of similar cost.

Typical patterns and cost of alcoholism treatment across a variety of populations and providers

This paper presents data on the utilization of alcoholism treatment services in three populations of insurance enrollees: enrollees covered by the insurance plan of a large midwestern manufacturing firm, 1981-1987 (N = 1.425); enrollees of the California Health Insurance Plan of the Public Employees Retirement System, 1974-1976 (N = 766); U.S. government civilian employees enrolled with the Aetna Insurance Company, 1980-1983 (N = 1,697). The average age of the treated alcoholics in these three groups ranged from 37 to 51. Between two-thirds and three-quarters were male. Inpatient alcoholism treatment services were more frequently used than outpatient, with inpatient admissions averaging between 1.2 and 1.5 per person. For enrollees of the midwestern manufacturing firm, total alcoholism treatment costs averaged $4,665 per person (December 1985 dollars). The influence of insurance plan coverage and other factors on utilization patterns is discussed.

The cost-effectiveness of psychotherapy: a plan for research

The authors assess gaps in the current knowledge base on psychotherapy research and the cost-effectiveness of psychotherapy. Despite the considerable and increasingly sophisticated body of research on the efficacy of psychotherapy, there is an alarming paucity of studies focusing on the cost-effectiveness of psychotherapy. This problem is particularly evident in the absence of studies exploring nonclinical effects of treatment and the broader range of domains in which intervention may have an impact. Initiation of research on the cost-effectiveness of psychotherapy is important for ensuring good clinical practice and data-based policy formulation. What is needed is greater specificity regarding the populations and problems for which psychotherapy can provide the greatest benefits, identification of the variables, measures, and methodological approaches that are most useful in yielding these important data, and comprehensive quantification of the costs and effects of psychotherapy.
