GST Pull-Down Assay to Study PIF4 Binding In Vitro

The phytochrome-interacting factor 4 (PIF4) is a well-known transcription factor that plays a pivotal role in plant thermomorphogenesis, coordinating growth and development in response to temperature changes. As PIF4 functions by forming complexes with other proteins, determining its interacting partners is essential for understanding its diverse roles in plant thermal responses. The GST (glutathione-S-transferase) pull-down assay is a widely used biochemical technique that enables the investigation of protein-protein interactions in vitro. It is particularly useful for studying transient or weak interactions between proteins. In this chapter, we describe the GST pull-down approach to detect the interaction between PIF4 and a known or suspected interacting protein. We provide detailed step-by-step descriptions of the assay procedures, from the preparation of recombinant GST-PIF4 fusion protein to the binding and elution of interacting partners. Additionally, we provide guidelines for data interpretation, quantification, and statistical analysis to ensure robust and reliable results.

Intracellular trafficking and glycosylation of hydroxyproline-O-glycosylation module in tobacco BY-2 cells is dependent on medium composition and transcriptome analysis

Expression of recombinant proteins in plant cells with a "designer" hydroxyproline (Hyp)-O-glycosylated peptide (HypGP), such as tandem repeats of a "Ser-Pro" motif, has been shown to boost the secreted protein yields. However, dramatic secretion and Hyp-O-glycosylation of HypGP-tagged proteins can only be achieved when the plant cells were grown in nitrogen-deficient SH medium. Only trace amounts of secreted fusion protein were detected in MS medium. This study aims to gain a deeper understanding of the possible mechanism underlying these results by examining the intracellular trafficking and Hyp-O-glycosylation of enhanced green fluorescent protein (EGFP) fused with a (SP)32 tag, consisting of 32 repeats of a "Ser-Pro" motif, in tobacco BY-2 cells. When cells were grown in MS medium, the (SP)32-EGFP formed protein body-like aggregate and was retained in the ER, without undergoing Hyp-O-glycosylation. In contrast, the fusion protein becomes fully Hyp-O-glycosylated, and then secreted in SH medium. Transcriptome analysis of the BY-2 cells grown in SH medium vs. MS medium revealed over 16,000 DEGs, with many upregulated DEGs associated with the microtubule-based movement, movement of subcellular component, and microtubule binding. These DEGs are presumably responsible for the enhanced ER-Golgi transport of HypGP-tagged proteins, enabling their glycosylation and secretion in SH medium.

Managed care and children's behavioral health services in Massachusetts

OBJECTIVE

The authors investigated changes in treatment patterns and costs of care for children after the implementation of the Massachusetts Medicaid carve-out managed care plan.

METHODS

The authors hypothesized that after the introduction of managed care, per-child expenditures would be reduced, continuity of care would not improve, and per-child mental health expenditures would undergo larger reductions for disabled children, compared with children enrolled in the Aid to Families With Dependent Children program. Using data from Medicaid and the Massachusetts Department of Mental Health, the authors studied 16,664 Massachusetts Medicaid beneficiaries aged one to 17 years for whom reimbursement claims were submitted for psychiatric or substance use disorder treatment at least once during the two years before the introduction of managed care (1991 to 1992) or during the two years afterward (1994 to 1995). Multivariate analysis was used to estimate changes in probability of admission, and, among patients admitted, to identify factors accounting for variation in length of stay. To assess the variation in expenditures, we regressed the same variables, using the natural logarithm function to transform total mental health expenditures data and inpatient expenditures data to reduce skewness.

RESULTS

After the introduction of managed care, per-child expenditures were lower, especially for disabled children, and the Department of Mental Health was used as a safety net for the most seriously ill children without increasing state expenditures. Continuity of care appeared to decline for disabled children.

CONCLUSIONS

It is likely that a combination of factors related to the reported changes in patterns of care and expenditures were responsible for the overall per-child expenditures.

Review of programs for persons who are homeless and mentally ill

Despite recent prosperity in the U.S., homelessness is still a widespread social problem. It is estimated that 25% of homeless persons have a serious mental illness. This article will review the literature evaluating prevention services and specialized outreach, treatment, and housing programs designed to reduce homelessness for individuals who are mentally ill. Although these interventions have been helpful in addressing the complex needs of the homeless mentally ill, it is difficult to measure how they have improved outcomes. It is even more challenging to determine whether the programs are cost-effective. Since public resources are used to maintain services for the homeless mentally ill, policy-makers must be informed about whether the best outcomes are achieved at the lowest possible cost. Following a discussion of the successes of the individual programs and the challenges they confront, several important questions are identified related to improving the efficiency of these programs. Although the establishment of such programs indicates that progress has been made toward alleviating the burdens facing people who are homeless and mentally ill, collaboration among all stakeholders-especially between the mental health community and consumer advocates-needs to be further enhanced. New research can be conducted in a way that improves how information is evaluated and used.

Outcome assessment in women's mental health

This is the fifth in a series of six papers that will be published from the 1999 lecture series on "Quality Assessment in Women's Health Care" held at the University of Michigan School of Public Health. The lectures are presented by leaders in women's health research, and they explore key issues in the definition, measurement, and improvement of quality in women's health services. The series is supported by an unrestricted educational grant from Pfizer Inc. and is presented by the Interdepartmental Concentration in Reproductive and Women's Health at the University of Michigan School of Public Health; the University of Michigan National Center of Excellence in Women's Health; and the Michigan Initiative for Women's Health. The series coordinator is Carol S. Weisman, PhD, and Catherine L. Maroney prepared the summary of the discussants' comments.

A self-report symptom and problem rating scale to increase inpatients' involvement in treatment

OBJECTIVE

The study sought to determine whether psychiatric inpatients who completed a self-report symptom and problem rating scale on admission and reviewed the results with a clinician would perceive at discharge that they had been more involved in their treatment than patients who did not complete the scale.

METHODS

In a quasiexperimental design, 109 inpatients were assigned to one of three groups. Patients in one group met individually with a psychiatric resident to review their responses to the Behavior and Symptom Identification Scale (BASIS-32), a self-report outcome assessment tool. Patients' views of their difficulties were then used by the treatment team to build a therapeutic alliance and to inform treatment planning. The remaining two groups received treatment as usual by either a psychiatric resident or an attending psychiatrist. Patients' perceived involvement in decisions about their treatment, perceptions of other aspects of care, and treatment outcome were compared.

RESULTS

Patients in the intervention group rated their involvement in decisions about their treatment significantly higher than patients in either of the comparison groups. Patients in the intervention group more frequently reported that they were treated with respect and dignity by the staff than did patients in the comparison group treated by attending psychiatrists. Compared with patients treated by attending psychiatrists, patients treated by residents, whether they received the intervention or not, were more likely to say that they would recommend the hospital to others. Treatment outcome did not differ among the groups.

CONCLUSIONS

The results suggest that an outcome assessment tool can be used to engage patients in the treatment process.

Cost-shifting in manged care

We conducted a study of the change from fee-for-service to managed care for mental health services in the Massachusetts Medicaid program, which occurred in fiscal year 1993. We estimated the effect of managed care on total public expenditures over both the short and the long term. Per person expenditures were lower by 24% in the first year of managed care but only lower by 5% in the second and third years. We also tested for cost-shifting by estimating expenditures for five specific services paid by three public agencies. Expenditures on services paid by the managed care vendor decreased, expenditures paid by Medicaid increased, and expenditures paid by the Department of Mental Health decreased. We discuss the implications for both cost-shifting and quality of care improvements. The results from two-part expenditure models indicate that some cost-shifting may be related to quality improvement. The effects are generally stronger for the beneficiaries in the highest quartile of expenditures.

Barbara Dickey on outcomes measurement, continuous quality improvement, and performance indicators. Interview by Christy L. Beaudin

Barbara Dickey, PhD, is director of the mental health services research department at McLean Hospital in Belmont, MA, and associate professor of psychology in the department of psychiatry at Harvard Medical School. Her research interests have focused on managed care and its effect on cost, outcomes, and quality. Related to these research interests is her work at McLean Hospital to use data-driven activities to improve the quality of patient care. Outcomes measurement, continuous quality improvement (CQI), and the use of performance indicators in the facility's widely distributed report cards, McLean Reports, are all supported by her department. She received the Partners in Excellence Award in 1996 from the Partners Health Care System, Inc., and has served on many ad hoc committees for the National Institute of Mental Health, National Institute of Alcohol and Drug Abuse, and the Agency for Health Care Policy and Research (AHCPR). Dr. Dickey is coeditor of Outcomes Assessment in Clinical Practice (1996) and the forthcoming book, Achieving Quality in Psychiatric and Substance Abuse Practice: Concepts and Case Reports.

Regional variation in service system performance: comparing the perceptions of key stakeholders

Area variation studies rarely focus on perceptions of service system performance in their comparative analyses. Using an instrument designed specifically for assessing key stakeholders' perceptions of the performance of mental health service delivery systems, this study compared three areas in Massachusetts that differ significantly with regard to service system structure and resource allocation. Despite these differences, key stakeholders' perceptions of service adequacy, availability, quality, and coordination did not vary substantially, although the findings suggest that to some extent organizational structure may have more effect than resource availability and allocation on perceptions of key stakeholders within the three systems. These differences were also of far less magnitude than differences in hospitalization rates and other more traditional measures of service system performance. The authors argue that stakeholders' perceptions should be considered, along with other standard performance measures, in evaluating service system performance.

Evaluating mental health care reform: including the clinician, client, and family perspective

This article suggests one direction that theory building might take to develop a stronger conceptual foundation needed to test the effect on clients of reforms in the financing and organization of mental health care delivery systems. The authors recommend that health status outcomes be measured from three perspectives: the client, who can best report his or her own subjective experience of illness; the clinician, who is the best source of information about the client's disease; and the family, which is the best source of information about the effects on members' health status of caring for a mentally ill family member. The authors also recommend that measurement of health status should be multidimensional.

The impact of preadmission approval and continued stay review on hospital stay and outcome among children and adolescents

Managed care has emerged as the centerpiece of the health care industry's efforts to control costs and ensure appropriate use of hospital services. This study assesses the impact of managed care by preadmission approval and/or continued stay review on length of psychiatric hospitalization and clinical outcome of children and adolescents. The sample included 277 cases hospitalized in nine psychiatric specialty hospitals in 1990. Demographic and clinical characteristics, hospital ownership type, and preadmission approval or continued stay review were used as independent variables in a multiple regression model to predict length of stay and clinical outcome. Results indicate that the model accounted for 27% of the variance in length of stay. Previous psychiatric hospitalization and for-profit hospital status predicted longer hospitalization. Clinical outcome was not significantly predicted by the model. Managed care did not predict either length of stay or clinical outcome. Implications for health care reform are discussed.

An ethnographic study of the meaning of continuity of care in mental health services

OBJECTIVE

As a step toward developing a standardized measure of continuity of care for mental health services research, the study sought to identify the interpersonal processes of giving and receiving day-to-day services through which individual providers create experiences of continuity for consumers.

METHODS

Ethnographic methods of field observation and open-ended interviewing were used to investigate the meaning of continuity of care. Observations were carried out at two community mental health centers and a psychiatric emergency evaluation unit in Boston. Sixteen recipients and 16 providers of services at these sites were interviewed.

RESULTS

Six mechanisms of continuity were identified, labeled, defined, and described through analysis of field notes and interview transcripts: pinch hitting, trouble shooting, smoothing transitions, creating flexibility, speeding the system up, and contextualizing. The mechanisms elaborate dimensions and principles of continuity cited by other observers and also suggest new formulations.

CONCLUSIONS

The mechanisms identified in this study facilitate operationalization of the concept of continuity of care by specifying its meaning through empirically derived indicators. Ethnography promises to be a valuable methodological tool in constructing valid and reliable measures for use in mental health services research.

How managed care organizations develop selective contracting networks for psychiatric inpatient care: a Massachusetts case study

Medicaid agencies recently have adopted selective contracting to control use and costs of publicly financed behavioral health care. This case study describes formation of an inpatient network for serving psychiatrically disabled Medicaid beneficiaries in Massachusetts. Network formation is seen as a two-stage process: hospitals first decide to bid for a contract, and form a pool from which the managed care organization chooses hospitals. We used logit models to predict how hospital experience with Medicaid patients, competition, prior reimbursement rates, and geographic distribution affected these two stages. Hospitals are more likely to bid if they have treated more psychiatric inpatients and more disabled Medicaid inpatients receiving Supplemental Security Income. Managed care organizations take into account hospitals' experience with Medicaid patients and geographic dispersion, but not prior reimbursement rates.

Assessing the quality of psychiatric care: research methods and application in clinical practice

The drive to contain the costs of health care in the United States is focusing attention on how quality of care is affected. This article discusses research methods for assessing the quality of psychiatric care and reviews findings from some major studies evaluating care. These findings are mixed, highlighting areas in which quality of care is less than optimal, as well as the importance of continued research and the need to develop better research methods. Evidence-based criteria and more-sensitive risk-adjustment techniques must be employed if data on quality are to yield fair comparisons among health plans. The challenge is to refine the methods now in use at both the research and clinical levels, so that better-quality assessments can be made for policy formulation, physician education, and consumer choice.

The cost and outcomes of community-based care for the seriously mentally ill

OBJECTIVE

To examine the cost-effectiveness of community-based mental health care.

DATA SOURCES/STUDY SETTING

Administrative data from Medicaid and the Massachusetts Department of Mental Health; primary data from 144 psychiatrically disabled adult Medicaid beneficiaries who lived in Boston, central Massachusetts, and western Massachusetts.

STUDY DESIGN

A cross-sectional observational study compared the costs and outcomes of treatment in three different types of public mental health service systems.

DATA COLLECTION/EXTRACTION METHODS

Beneficiaries, randomly sampled from outpatient mental health programs, were interviewed about their mental health status. All their acute treatment and long-term continuing care for the preceding year were abstracted from Medicaid and Department of Mental Health files. Costs were extracted from Medicaid paid claims and from Department of Mental Health contracts and other financial documents.

PRINCIPAL FINDINGS

Clients in the region allocating a greater proportion of its Department of Mental Health budget to community support services used far fewer hospital days, resulting in lower per person treatment expenditures. Outcomes, however, were not significantly different from outcomes of clients in the other regions. For all regions, substance abuse comorbidity increased hospitalization and total treatment costs. An individual-level cost-effectiveness analysis identified western Massachusetts (community-based care) as significantly more cost effective than the other two regions.

CONCLUSIONS

Systems with stronger community-based orientation are more cost effective.

Assessing cost and utilization in managed mental health care in the United States

Mental health cost containment in the United States has evolved from fragmented utilization review and discounted pricing programs in the 1980s to comprehensive mental health managed care programs in the 1990s, in which the network managing the care takes on financial risks associated with price and utilization for all mental health services provided to an enrolled population. While the earlier programs did not control costs to any significant degree, the newer forms of managed mental health are showing substantial reductions in cost, primarily through the reduction in use of in-patient services. Based on these encouraging but very preliminary results, state Medicaid programs have increasingly embraced managed care for both medical and mental health services for eligible low-income populations. However, little has been systematically evaluated with respect to the effects of aggressive mental health care management upon quality of care, functional outcomes or patient satisfaction. In addition, substantial new investment in merged clinical and financial information systems raises the entry cost significantly for managed care providers.

Assessing outcomes in clinical practice

We are witnessing a remarkable explosion in interest and activity in quantifying outcomes and using these measures to enhance the value of clinical care. Outcomes assessment has become an imperative for clinical practice. This paper first will offer criteria for an ideal system of outcomes assessment. The paper will then review the principal domains of assessment for psychiatric practice and provide examples of instruments available in each domain. We will then describe the use of two instruments, one for clinical outcome and one for interpersonal aspects of patient satisfaction, developed and used at McLean Hospital. The relation between outcomes assessment and outcomes management will then be discussed. Finally, we will discuss the fundamental questions a clinical group or facility might consider in choosing outcomes measurement instruments.

Cost shifting in a mental health carve-out for the AFDC population

This study tests whether the managed care vendor shifted costs to Medicaid-reimbursed medical care after the start of the mental health carve-out for the Aid to Families with Dependent Children (AFDC) population in Massachusetts. We used claims data over a 4-year period to estimate expenditures for four types of health services, two of which were paid for by the managed care vendor and two by Medicaid. Total per person public expenditures declined by only about 3 percent. Inpatient psychiatric services were replaced by outpatient psychiatric services and some pharmaceuticals, but overall there was little or no evidence of cost shifting to the medical sector. These results are in contrast to what was found in a sample of Medicaid beneficiaries eligible due to a mental health disability.

Housing costs for adults who are mentally ill and formerly homeless

The goal of this study was to evaluate the costs, under two different housing conditions, to the state mental health agency of caring for adults who are homeless and mentally ill. One hundred and twelve clients of the Massachusetts Department of Mental Health, living in psychiatric shelters, were randomly assigned to one of two housing types: Evolving Consumer Households or Independent Living apartments. For the next 18 months each client was followed so that the cost of treatment, case management, and housing could be collected and compared. The authors found that treatment and case management costs did not vary by housing type, but housing costs were significantly higher for those assigned to Evolving Consumer Households. Regardless of original housing assignment, treatment costs were lower for clients who remained where they were originally placed. The authors conclude that providing support for clients that increases housing stability reduces their need for treatment and that independent living arrangements may be a more cost-effective policy choice.

Managing the care of schizophrenia. Lessons from a 4-year Massachusetts Medicaid study

BACKGROUND

In 1992, Massachusetts launched a state-wide managed care plan for all Medicaid beneficiaries.

METHODS

This retrospective, multi-year, cross-sectional study used administrative data from the Massachusetts Division of Medical Assistance and Department of Mental Health, consisting of claims for 16,400 disabled adult patients insured by Medicaid in Massachusetts between July 1, 1990, and June 30, 1994. The main outcome measures include annual rates of hospitalization, emergency department utilization, and follow-up care 30 days after discharge; length of inpatient stay; and per-person inpatient and outpatient expenditures.

RESULTS

Between 1991 and 1994, the likelihood of an inpatient admission decreased from 29% to 24% and was accompanied by a slight reduction in length of stay (median number of bed-days per admission dropped by 3.3 days). There was a slight decrease in the number of patients who sought care in general hospital emergency department utilization. However, there was a small increase in the fraction of patients readmitted within 30 days of discharge. Medicaid and Department of Mental Health expenditures for mental health per treated beneficiary decreased slightly, from $11,060 to $10,640, during the 4-year study period.

CONCLUSION

Although per-person expenditures dropped and most patient patterns of care remained the same, longer-term study is recommended to asses whether the trends can be maintained.

Persons with dual diagnoses of substance abuse and major mental illness: their excess costs of psychiatric care

OBJECTIVES

This study examined the costs of psychiatric treatment for seriously mentally ill people with comorbid substance abuse as compared with mentally ill people not abusing substances.

METHODS

Three different sources of data were used to construct client-level files to compare the patterns of care and expenditures of 16,395 psychiatrically disabled Medicaid beneficiaries with and without substance abuse: Massachusetts Medicaid paid claims; Department of Mental Health state hospital inpatient record files; and community support service client tracking files.

RESULTS

Psychiatrically disabled substance abusers had psychiatric treatment costs that were almost 60% higher than those of nonabusers. Most of the cost difference was the result of more acute psychiatric inpatient treatment.

CONCLUSIONS

Although the public health and financial costs of high rates of comorbidity are obvious, the solutions to these problems are not. Numerous bureaucratic and social obstacles must be overcome before programs for those with dual diagnoses can be tested for clinical effectiveness.

Use of mental health services by formerly homeless adults residing in group and independent housing

OBJECTIVE

The study examined patterns of mental health service use among 112 formerly homeless mentally ill adults to determine whether clients in a staffed group living situation would need fewer types of services or lesser amounts of some services than those living independently in single apartments.

METHODS

Clients in the Boston McKinney demonstration project were randomly assigned to two housing types: individual apartments or a group living situation designed to teach residents to manage the house and their own affairs with minimal staff presence. The types and amounts of services these clients used during an 18-month period were documented and compared.

RESULTS

Service use by all clients was heavy, especially use of inpatient psychiatric services. It did not differ by housing type. The large majority of clients in both housing types were able to remain housed and avoid homelessness. Clients who did not stay in assigned housing for the duration of the study had higher levels of inpatient service use, including detoxification and substance abuse treatment.

CONCLUSIONS

When homeless mentally ill adults are provided permanent housing and accessible mental health treatment and specialized social services, they are likely to avoid unstable housing patterns, which are associated with higher use of inpatient services.

Using health status measures with the seriously mentally ill in health services research

Changes in the delivery of mental health care have prompted interest in using generic health status measures to test the effect of system change on those receiving treatment. Of special concern are those with serious and persistent mental illness who may be neglected when cost containment efforts reduce the availability of treatment services. This population may be affected by these changes, which might go undetected if investigators use scales that measure only pathology and not the full spectrum of well-being. The purpose of this study was to test the feasibility of using self-report health status measures with this population, to describe the psychometric properties of the scales, and to report the health status scores of a random sample of the Medicaid psychiatrically disabled population. We found that the four health status scales had adequate psychometric properties, that score variability was high, the distributions normal, and that patterns of association with more traditional clinical measures were of the expected size and direction. One scale, General Health Perceptions, had reliability and item-to-score correlation below acceptable levels.

The imperative of outcome assessment in psychiatry

This report describes the current conceptualization of outcome assessment in psychiatry and focuses on how assessment instruments can be built into psychiatric facility-based practice. First, the domains of clinical assessment are outlined, with an emphasis on three elements: level of psychiatric symptoms, clinical functioning, and patient satisfaction. Examples of outcome instruments then are provided as well as the elements of their successful implementation. Finally, the value of linking outcome assessment to data on patient characteristics and service utilization are discussed in order to gain insight into the relationship between treatment and outcome. The clinical, fiscal, and regulatory imperatives emerging for outcome assessment call for its demystification and widespread application.

Acute and chronic psychiatric care: establishing boundaries

Despite advances in psychiatry, a proportion of those with mental illness have episodes of severe illness, and a few of these patients may attain only partial recovery. In this respect, mental illness is similar to physical illness and systems of acute and chronic care are essential. As mental health care financing and delivery systems undergo further flux and reform, we will require clear, consensually developed definitions of levels of care, especially because of the complexities created by a legacy of a 2-tiered, public and private mental health system. This paper first will offer definitions and examples of acute and chronic illness and care. We will also address certain problems inherent to such a classification. We will then consider principles of and potential plans for a system of financing and care for the chronically mentally ill. Two existing plans will be reviewed as illustrations of innovations in chronic care. As health reform changes the financing and delivery of care for the mentally ill, an opportunity exists to integrate public and private monies and services and to improve upon the care of the acutely and chronically mentally ill.

A comparison of for-profit and not-for-profit hospitals on the cost of mental health admissions

The debate around health reform has raised questions about costs of care and the nature of competition in the delivery of care. This study examines whether the profit incentive leads to more-cost-efficient delivery of psychiatric and substance-abuse care. The data are from paid claims for 561 psychiatric and substance-abuse admissions in 1985-1987 from two very large national corporations with generous indemnity health plans that included nondiscriminatory mental health benefits. We found that episode-paid claims for admissions to for-profit facilities, after adjustments for case-mix and facility type, were higher. The stays of children in for-profit hospitals, relative to those of adults, were longer and more expensive.

Patterns of service use and costs in model day hospital-in programs in Boston and Tucson

Patterns of service use and costs in two similar model day hospital-inn programs for psychiatric patients in publicly funded hospitals in Boston and Tucson are compared. Implementation of the programs resulted in cost savings at both sites, although mean annual costs per patient were much lower in Tucson than in Boston. Compared with patients at the Boston site, patients in Tucson had more admissions but shorter stays and fewer days in the program during a 12-month follow-up period. Site-specific differences in the programs, in local practice patterns, and in state mental health funding levels may have influenced cost differences.

Containing mental health treatment costs through program design: a Massachusetts study

A single site pre-post study of seriously mentally ill patients treated in a public mental health system shows that annual treatment costs can be substantially reduced with the use of day hospital treatment. Two cohorts of psychiatric patients--282 consecutive admissions to a traditional public inpatient unit in 1980, and 340 consecutive admissions to a combination of inpatient and day hospital care in 1984--were followed 12 months after admission. The substitution of the day hospital is made possible because the facility provided a dormitory residence for those who could not go home at night. Cost savings per hospital episode are about 31 per cent when the additional costs of day hospital and residence are considered. Cost shifting from inpatient to residential sites is noted, but overall mean annual costs, when all other treatment (including additional admissions), residential and family costs were included, are reduced. Readmission rates did not rise. The generalizability of the findings is limited to public mental health centers and state hospitals.

Differences in resource use and cost among facilities treating alcohol, drug abuse, and mental disorders: implications for design of a prospective payment system

Specialized psychiatric facilities, including qualified distinct-part units in general hospitals, are exempt from Medicare's diagnosis-related group prospective payment system (PPS). One major reason for continuing the exemption is the redistribution of revenue that would probably occur if a single national price were established for care at the diverse facilities that treat patients with psychiatric and substance abuse disorders. This study investigated the extent of such potential redistribution in a private health insurance data base and found that a PPS would systematically underpay specialized facilities and systematically overpay general hospitals without specialized units. Alternatives for addressing this problem are discussed.

Bringing psychiatric patients into the Medicare prospective payment system: alternatives to DRGs

The basis of Medicare's prospective payment for alcohol, drug abuse, and mental illness hospital admissions has been the patient classification system known as diagnosis-related groups (DRGs). This paper describes two alternative patient classification systems, disease staging and clinically related groups, and reports how well each system predicts resource use compared to the DRG system. Medicare data from four states were used to test the comparative strength of these patient classification systems. Although disease staging and clinically related groups performed better than DRGs, they were still poor predictors of resource use.

The Quarterway House: a two-year cost study of an experimental residential program

A comprehensive cost comparison was made of resource utilization by seriously disabled chronic psychiatric patients randomly assigned to inpatient care and to an experimental residential program that provided an intermediate level of 24-hour care. At the end of the two-year study period, no significant changes in patients' clinical condition were observed, but costs for the experimental group averaged about $14,500 less (in 1981 dollars) than for the controls. The cost model included all treatment costs and nontreatment costs such as medical care, community services, case management, law enforcement and fire safety, maintenance outside the mental health system, and collateral costs. The study findings suggest that a program such as this one may be a viable alternative to back-ward long-term care for seriously disabled chronic patients.

Mental health cost models. Refinements and applications

This paper describes a 2-year study whose goal was to refine Burton Weisbrod's cost model for public programs for the chronically mentally ill. The authors made comprehensive cost assessments of all the resources, including treatment programs, used by a small sample of severely disturbed chronically ill patients. Refinement of the model included a method to assess capital costs of public facilities. The use of disaggregated patient information permitted analysis of cost differences between patients when adjusted for case mix. Patient costs over the study period ranged from $24,000 to $99,000. Patient characteristics and change in clinical status account for 30% of the variance.

Four-year assessment of a day hospital-inn program as an alternative to inpatient hospitalization

The authors report on a new system of care in which all patients who require psychiatric hospitalization are admitted to a day hospital with an inn and an intensive care unit. Data on use of services, length of stay, recidivism, security, medical emergencies, staff accidents, and seclusion and restraint over a 4-year period suggest that the new delivery system provides care which is at least as effective as the previous system of care. Evidence is presented that the new system offers certain advantages, including less seclusion and restraint, fewer episodes of escape, and substantial cost savings.

From inpatient to inn status. A new residential model

This article presents a new residential model that has been developed at the Massachusetts Mental Health Center. The "dormitory-inn" provides an alternative to 24-hour inpatient hospitalization for patients who traditionally would have been admitted and retained on inpatient services. Issues covered include hours and location, referrals, requirements for staff, medical and nursing coverage, and a review of the efficacy of the program.

Career patterns of female and male graduates of a psychiatric residency program

The authors surveyed 122 recent graduates of the Massachusetts Mental Health Center to determine whether previously reported differences in career patterns between the sexes persist in younger psychiatrists. Some of the findings are consistent with previous studies, e.g., women work fewer hours than men, take more time off for child rearing, and are less often Board certified. However, women surveyed were not underpaid compared with men, and men showed a growing awareness of the conflicting demands of career and family. The significance of these findings and their implications are discussed.

Alternative to the back ward: the quarterway house

The Quarterway House was founded in December 1978 to deinstitutionalize and provide rehabilitation services to a small group of long-term, seriously ill inpatients of the Massachusetts Mental Health Center. The purposes of the residential program are to provide a less institutional therapeutic environment and to develop a psychosocial treatment program that might enable some patients to move toward more independent settings in the community. In a randomized experimental study, with center inpatients as the control group, the effectiveness of the program was assessed by multiple outcome measures before the program began and at one year. Although neither group moved rapidly to more independent community living, Quarterway House patients showed improvement in general functioning and socialization-survival skills and decreased medication and seclusion. They did not show a decline in psychotic symptoms, obstreperousness, or antisocial behavior. Over-all, the findings suggest the program may prove useful for the long-term rehabilitation of severely ill patients.

A follow-up of deinstitutionalized chronic patients four years after discharge

Twenty-seven chronically ill mental patients were followed up four years after their discharge from a state hospital to the Massachusetts Mental Health Center. In interviews with the patients and their caregivers, data were gathered on the patients' current places of residence, mental status, time spent in the hospital since discharge, levels of functioning, and quality of life. The authors found that patients tended to move from hospital to community, with rehospitalization dropping dramatically once patients were placed in the community; that the group of patients living in the community had a better average mental status; that all but two patients preferred their current living situations to life at the state hospital; and that the best predictor of community residence was age at first admission (over 20). Two policy issues are discussed: the relationship (or lack of one) between restrictiveness and type of residence, and the importance to the findings of changes in psychiatric practice over the lifetime of the sample.
