Issues and approaches in evaluating managed mental health care.

Data on the ways in which alternative forms of managed care affect the costs, quality, and outcomes of mental health are needed to inform health policy and clinical care decisions. Such evaluations, however, are difficult to implement for conceptual and practical reasons. The definition of managed mental health care is reviewed, alternative forms are described, and the activities and procedures that constitute managed care are identified. Examples from existing studies are used to describe the common roadblocks to implementing evaluations and to suggest methods for dealing with these barriers.

Impact of prior and current alcohol use on use of services by patients with depression and chronic medical illnesses.

OBJECTIVE: Alcohol use often co-occurs with other major chronic conditions, but its effect on health care utilization in this context is not understood. This study examines the impact of alcohol consumption on health care use by patients with chronic medical conditions or depression, or both. DATA SOURCES/STUDY SETTING: Data came from the Medical Outcomes Study, an observational study of patients from the offices of general medical providers and mental health specialists in three U.S. cities. STUDY DESIGN: Longitudinal data spanning four years for outpatient general medical visits and outpatient mental health visits were analyzed using a two-part model to assess the impact of alcohol use disorder, problem drinking, and current and past alcohol consumption on health care use by patients, controlling for patient demographics and health status. DATA COLLECTION/EXTRACTION METHODS: Data were collected from 2,546 adult patients with hypertension, diabetes, heart disease (congestive heart failure or myocardial infarction), and/or current major depression or subthreshold depression using periodic, self-report surveys detailing health care utilization and health status information. PRINCIPAL FINDINGS: Current alcohol consumption increases outpatient doctor visits, and problems related to current drinking decrease outpatient mental health visits. CONCLUSIONS: Patterns of alcohol consumption have an impact on both mental health and overall health care use by patients with chronic medical conditions or depression.

Clinician specialty and treatment style for depressed outpatients with and without medical comorbidities.

BACKGROUND: The advent of clinical practice guidelines for the management of depression increases the importance of understanding variation across clinician specialty groups in treatment styles for depression and the role of medical comorbidities. METHODS: Data are reported by clinicians (N = 470) and patients (N = 2545). Multiple regression was used to compare the treatment styles (counseling and prescribing antidepressants) of family physicians with those of psychiatrists, medical subspecialists, internists, psychologists, and other therapists for depressed patients with different medical comorbidities. RESULTS: Relative to other primary care specialists, family physicians had the strongest preferences for both counseling and prescribing antidepressants for depressed patients. Family physicians reported preferences for treating with antidepressants that were similar to those of psychiatrists. However, in actual practice, medication use was higher among the patients of psychiatrists than those of family physicians. Mental health care specialists reported the strongest counseling preferences and provided the most counseling in actual practice, compared with general medicine physicians. Internists and subspecialists had similar preferences for prescribing antidepressants, but, compared with internists, subspecialists had lower preferences for counseling. Clinician preferences for counseling were similar for depressed patients with or without medical comorbidities, but preferences for prescribing antidepressants were lowest for patients with depression and myocardial infarction, compared with other patient groups. CONCLUSIONS: Measures of clinician treatment style for depression are good proxies for counseling but not for prescribing practices. Among general medical physicians, family physicians have the strongest reported preferences in treating depression but, especially in terms of medication therapy, do not always follow those preferences. Preferred treatments of patients with and without medical comorbidities were similar. Findings have implications for improving the quality of treatment of depressed patients.

Quality of antidepressant medications prescribed at discharge to depressed elderly patients in general medical hospitals before and after prospective payment system.

This study describes the quality of antidepressant medication use at hospital discharge for depressed elderly inpatients and compares quality of care before and after implementation of Medicare's Prospective Payment System (PPS). The study reviewed data from medical records of 2746 depressed, elderly, hospitalized patients in acute-care general medical hospitals in five U.S. states (pre-PPS period 1981-82; post-PPS period 1985-86). The majority were discharged on antidepressant medication both pre-PPS and post-PPS. After PPS' implementation, sedating medications were used less often in all treatment settings. In general medical wards, a higher percentage post-PPS (24%) than pre-PPS (14%) were discharged 48 hours or less after first starting an antidepressant medication. In both time periods, one-third of patients receiving antidepressant medications were prescribed daily dosages at discharge below recommended, minimum, therapeutic levels, whether treated in general medical wards or psychiatric units. Otherwise, patients previously treated in psychiatric units received higher quality of medication management than those treated in general medical wards. Over time, patients discharged on antidepressant medication were less likely to use sedating medication, suggesting improved quality of care. In general medical wards, however, patients were discharged more rapidly after starting medication, possibly suggesting lower quality of care. A substantial percentage of patients received subtherapeutic dosages of medication or sedating medications, suggesting that improved management of discharge antidepressant medication in the elderly is needed in general medical hospitals.

Long-term functioning and well-being outcomes associated with physical activity and exercise in patients with chronic conditions in the Medical Outcomes Study.

This study was carried out to determine whether levels of physical activity of patients with various chronic diseases are associated with subsequent functioning and well-being. It was an observational 2-year longitudinal design. The setting was offices of medical and mental health practices within health maintenance organizations, large multispecialty groups, and solo practices or small single-specialty group practices in three U.S. cities. Included in the study were 1758 adult patients with one or more of the following: diabetes, hypertension, congestive heart failure, recent myocardial infarction, depressive symptoms, or current depressive disorder. Outcome measures included physical, role, and functioning; energy/fatigue; pain intensity; sleep problems; depressed affect, anxiety, positive affect, and overall psychological distress/well-being; health distress; and current health perceptions. Cross-sectional (base-line), 2-year endpoint, and change score relationships were evaluated between baseline levels of physical activity and each outcome, controlling for chronic conditions, comorbidity, smoking, alcohol use, overweight, self-reported adherence, and other patient and study characteristics. Higher baseline levels of exercise were uniquely associated with better functioning and well-being at baseline and 2 years later for some measures. The magnitude of the differences varied by disease group, but tended to be between 0.17 and 0.39 of the baseline SD. Greater levels of exercise are associated with feeling and functioning better for patients with chronic conditions over a 2-year period, suggesting that this is a fruitful area for further study using controlled interventions.

Quality of care for depressed elderly pre-post prospective payment system: differences in response across treatment settings.

We evaluated the quality of care for depressed elderly patients (n = 2,746) hospitalized in general medical hospitals (n = 297) before or after implementation of Medicare's Prospective Payment System, focusing on whether the response to time period differed for hospitals that in the post-PPS period had no psychiatric unit, an exempt psychiatric unit, or a nonexempt unit, and by ward placement within hospitals with psychiatric units. Quality of care increased over time, and for most measures of quality of care the level of improvement did not differ significantly across different types of hospitals or by ward placement. The intensity of use of therapeutic services, such as rehabilitation, occupation, or recreation therapy, increased over time, particularly in nonexempt psychiatric units and hospitals without psychiatric units, such that these locations caught up some over time in the level of use of these services to the level for exempt psychiatric units. Several outcomes of care improved over time, and the degree of improvement in the rate of inpatient medical and psychiatric complications and other outcomes was significantly greater for psychiatric units that were exempt post-PPS than for nonexempt treatment locations.

Switches between prepaid and fee-for-service health systems among depressed outpatients: results from the Medical Outcomes Study.

We analyzed switches between prepaid and fee-for-service health care plans among depressed outpatients in the longitudinal part of the Medical Outcomes Study. Patients of mental health specialists in fee-for-service plans had the lowest adjusted rate of plan switching (8.1%), compared to fee-for-service general medical patients (13.5%) and prepaid patients of both types of providers (10.1% to 11.7%). Although there were no substantial differences in initial sickness by payment system among enrolled patients, differing switching rates by provider specialty and payment system indicated biased selection over time. In addition, we found that married, nonwhite, and wealthier individuals were significantly more likely to leave fee-for-service than prepaid care plans. We analyzed whether system switching had an effect on patient satisfaction and outcomes. None of the results were highly significant, but the power of the data to analyze this issue was limited. Nevertheless, it appears that patients switching from prepaid to fee-for-service may be at risk for poorer functioning outcomes, although there was no similar effect on mental health status.

Subthreshold depression and depressive disorder: clinical characteristics of general medical and mental health specialty outpatients.

OBJECTIVE: The authors examined the clinical significance of depressive symptoms below the threshold for depressive disorder in outpatient samples. METHOD: The subjects were 775 adult patients with current depressive disorder, 1,420 patients with subthreshold depression, and 1,767 hypertensive patients with and without depression, all of whom were visiting the offices of mental health specialists and general medical care providers in three U.S. cities. Data on demographic characteristics, severity of depression, extent of psychiatric and medical comorbidity, family psychiatric history, and treatment history for the patients with depressive disorder and those with subthreshold depression were compared. RESULTS: The percentage of patients with subthreshold depression who had a family history of depression (41%) was nearly as high as that of the patients with depressive disorder (59%). The two groups of patients had similar levels of medical and psychiatric comorbidity except for anxiety disorders, which were greater among the patients with depressive disorder. Among the hypertensive patients in the general medical sector, those with subthreshold depression were more similar to those with depressive disorder than to the nondepressed hypertensive patients. Treatment rates were considerably lower for patients with subthreshold depression than for patients with depressive disorder in the general medical sector, but they were similar in the mental health specialty sector. CONCLUSIONS: In these outpatients, subthreshold depression appeared to be a variant of affective disorder and was treated as such in the mental health specialty sector but not in the general medical sector. The findings emphasize the importance of treatment outcome studies of patients with subthreshold depression.

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.

Emotional and behavioral problems and severe academic delays among sheltered homeless children in Los Angeles County.

OBJECTIVES: Few studies have estimated the extent of specific emotional, behavioral, and academic problems among sheltered homeless children. The objectives of this study were to describe such problems, identify those children with the problems, and evaluate the relationship between child problems and use of physical and mental health services. METHODS: From February through May 1991, 169 school-age children and their parents living in 18 emergency homeless family shelters in Los Angeles County were interviewed. To evaluate the answers, interviewers used standardized measures of depression, behavioral problems, receptive vocabulary, and reading. RESULTS: The vast majority (78%) of homeless children suffered from either depression, a behavioral problem, or severe academic delay. Among children having a problem, only one third of the parents were aware of any problem, and few of those children (15%) had ever received mental health care or special education. CONCLUSIONS: Almost all school-age sheltered homeless children in Los Angeles County have symptoms of depression, a behavioral problem, or academic delay severe enough to merit a clinical evaluation, yet few receive specific care. Programs targeted at sheltered homeless school-age children are needed to close this gap.

Prevalence of comorbid alcohol disorder and consumption in medically ill and depressed patients.

OBJECTIVE: To estimate the extent to which alcohol disorder co-occurs in patients with major medical and psychiatric conditions. DESIGN: Observational study. SETTING: Offices of general medical providers and mental health specialists in three US cities. PATIENTS: Adult patients (N = 2296) with hypertension, diabetes, heart disease (congestive heart failure or myocardial infarction), and/or current depressive disorder or subthreshold depressive symptoms. MAIN OUTCOME MEASURES: Current and lifetime alcohol disorder, alcohol consumption, current problem drinking, perceived need for help for alcohol or other drug problems, and unmet need. METHODS: Comparisons of the prevalence of alcohol comorbidity in medically ill nondepressed patients of general medical providers and in depressed patients of both provider types. RESULTS: Patients with chronic medical problems or depression had similar levels of lifetime alcohol disorder (14% to 19%) and current alcohol problems (18% to 29%), but depressed patients were more likely to report needing help for problems with alcohol or drugs. Current alcohol disorder was more prevalent among depressed patients in mental health specialty practices than in general medical practices. Many patients who perceived a need for care for alcohol and other drug problems reported that this need was unmet (37% to 84%). CONCLUSIONS: Clinicians who treat patients with major medical and psychiatric conditions need to be prepared to identify and treat comorbid alcohol disorder.

Outcomes for adult outpatients with depression under prepaid or fee-for-service financing.

OBJECTIVE: To compare change over time in symptoms of depression and limitations in role and physical functioning of patients receiving prepaid or fee-for-service care within and across clinician specialties. METHOD: Observational study of change in outcomes over 2 years for 617 depressed patients of psychiatrists, psychologists, other therapists, and general medical clinicians in three urban sites in the United States. RESULTS: Psychiatrists treated psychologically sicker patients than other clinicians in all payment types. Among psychiatrists' patients, those initially receiving prepaid care acquired new limitations in role/physical functioning over time, while those receiving fee-for-service care did not. This finding was most striking in independent practice associations but varied by site and organization. Patients of psychiatrists were more likely to use antidepressant medication than were patients of other clinicians, but among psychiatrists' patients, there was a sharp decline over time in the use of such medication in prepaid compared with fee-for-service care. Outcomes did not differ by payment type for depressed patients of other specialty groups, or overall. CONCLUSION: Depressed patients of psychiatrists merit policy interest owing to their high levels of psychological sickness. For these patients, functioning outcomes were poorer in some prepaid organizations. The nonexperimental evidence favors (but cannot prove) an explanation based on care received, such as a reduction in medications, rather than on preexisting sickness differences.

Do depressed patients in different treatment settings have different levels of well-being and functioning?

Differences in the functioning and well-being of adult patients with current or past depressive disorder who visited clinicians of different specialties in health maintenance organizations, solo practices, or large multispecialty group practices were examined. For patients in different systems, there were no significant differences in functioning and well-being across 12 domains tested. Patients of mental health specialists had worse mental health and more limitations in social activities, whereas patients of medical clinicians had worse physical functioning, more pain, more physical/psychophysiologic symptoms, and worse health perceptions. Thus, each system of care had depressed patients with a similar functioning and well-being "burden" but specialty sectors had patients with slightly different functioning and well-being profiles, probably reflecting patient selection of type of provider.

Risk factors for secondary depression among Mexican Americans and non-Hispanic whites. Alcohol use, alcohol dependence, and reasons for drinking.

We evaluated demographic (age, gender, income), cultural (ethnicity, acculturation), clinical (alcohol use, alcohol dependence), and motivational (subjective reasons for drinking) potential risk factors for secondary depression in 372 persons with lifetime alcohol abuse or dependence (from a randomly selected community sample of 2393). Lifetime alcohol abuse or dependence increased the risk of major depression by a factor of approximately 2 to 7. Recent secondary depression was present in 2% to 18% of persons meeting criteria for alcohol use disorders. Low income, female gender, and among Mexican Americans, low acculturation were associated with increased risk of secondary depression. Persons with lifetime alcohol diagnoses who currently drank, but did not name relaxation as a reason for drinking, were also at higher risk for secondary depression. Drinking to forget was associated with increased risk of secondary depression among Mexican American alcoholics, but not among non-Hispanic white alcoholics. Current abstinence was associated with greater risk among lifetime alcoholics born in Mexico, but not among those born in the United States.

Quality of care for hospitalized depressed elderly patients before and after implementation of the Medicare Prospective Payment System.

OBJECTIVE: The authors evaluated the impact of Medicare's Prospective Payment System on aspects of quality of care and outcomes for depressed elderly inpatients in acute-care general medical hospitals. METHOD: The depressed elderly inpatients (N = 2,746) were hospitalized in 297 acute-care general medical hospitals. The authors used a retrospective before-and-after design, controlling for differences over time in sickness at admission. Quality of care and outcomes were assessed through clinical review of explicit and implicit information in the medical records; secondary data sources provided information on postdischarge outcomes. RESULTS: After implementation of the prospective payment system 1) a higher percentage of patients had clinically appropriate acute-care admissions; 2) the initial assessment of psychological status by the treating provider was more complete; 3) the quality of psychotropic medication management, as rated by the study psychiatrists, improved; 4) the rates of any inpatient medical or psychiatric complication, of discharge to another hospital or a nursing home, and of inpatient readmission declined; and 5) there was no marked change in the percentage of patients rated by study clinicians as having acceptable overall clinical status at discharge or the rate of mortality 1 year after admission. CONCLUSIONS: After the implementation of the Medicare Prospective Payment System, the quality of care for depressed elderly inpatients improved and there was no marked increase in adverse clinical outcomes. Despite these gains, after implementation the quality of care was moderate at best and over one-third of the patients had unacceptable clinical status at discharge.

Partial hospitalization (day treatment) for psychiatrically ill elderly patients.

OBJECTIVE: The purpose of this paper is to present initial findings from a retrospective chart review of geriatric day treatment patients in order to focus attention on this potentially important area, add to the limited database in this area, and generate hypotheses for future investigations. METHOD: Data were abstracted from the charts of 100 geriatric day treatment patients over a period of approximately 5 years (1985-1989). Descriptive, univariate, and multiple regression techniques were used to describe the patients and identify variables associated with their outcomes. RESULTS: The typical patient in this program was a widowed white woman in her 70s who suffered from a depressive disorder. During the initial treatment period (usually approximately 3 months), 57% of the patients experienced some clinical improvement. Variables associated with a favorable outcome included diagnosis of a mood disorder rather than a psychotic disorder, better initial functional status, greater initial social support, fewer stressful events during treatment, and longer duration of treatment. CONCLUSIONS: Geriatric day treatment can be effective and merits further study as a mode of treatment for psychiatrically ill elderly patients.

Course of depression in patients with hypertension, myocardial infarction, or insulin-dependent diabetes.

OBJECTIVE: The authors examined the course of depression over 2 years for outpatients with and without a history of hypertension, a history of myocardial infarction, or current insulin-dependent diabetes. METHOD: Among outpatient visitors to the practices of 523 general medical clinicians and mental health specialists, 626 depressed patients were followed for 1 or 2 years with a telephone-administered interview based on the format of the National Institute of Mental Health Diagnostic Interview Schedule. RESULTS: Depressed patients with and without medical illness had high rates of persistent depressive symptoms and spells over 2 years. Patients with a lifetime history of myocardial infarction had significantly more spells of depression over the first follow-up year, more total symptoms of depression in the second follow-up year, and more depressive symptoms at the end of each follow-up year than depressed patients without myocardial infarction. The course of depression did not differ significantly for depressed patients with and without a lifetime history of hypertension or current insulin-dependent diabetes. CONCLUSIONS: Among depressed adult outpatients, a history of myocardial infarction is associated with a particularly poor clinical prognosis. A relatively high percentage of all depressed patients in this study had persistent depression regardless of the extent of medical comorbidity.
