Client outcomes in a three-year controlled study of an integrated service agency model.

OBJECTIVE: In a three-year controlled study, two California integrated service agency demonstration programs that combined structural and program reforms were tested to see if they produced improved outcomes for a cross-section of clients with severe and persistent mental illness. METHODS: Clients at an urban site and a rural site were randomly assigned to an integrated service agency program or to a comparison group who received the usual services. Data on client outcomes, were drawn from databases and client and family interviews. RESULTS: Compared with the comparison groups, clients served by the integrated service agencies had less hospital care, greater workforce participation, fewer group and institutional housing arrangements, less use of conservatorship, greater social support, more leisure activity, less family burden, and greater client and family satisfaction. Clients in the urban demonstration program, but not those in the rural program, did better than the comparison group on measures of financial stability, personal well-being, and friendship. At the urban site, 72.6 percent of clients participated in the work force during the three-year study period, compared with 14.6 percent of the clients in the comparison group. No differences were found at either site in rates of arrest and conviction and in self-reported ratings of self-esteem, symptoms, medication compliance, homelessness, and criminal victimization. The capitated costs for demonstration clients were much higher than the costs for services used by comparison clients. CONCLUSIONS: Three-year outcomes for a cross-section of clients with severe mental illness in the integrated service agencies were broadly favorable, but costs of services for those clients were high relative to costs for clients receiving the current standard of care.

Estimating the cost impact of three dual diagnosis treatment programs.

Specialized intervention programs for people with concurrent severe mental illness and substance abuse reduce the total costs of care. Compared to baseline, cost savings of over 40% were achieved by 18 months, primarily due to significant reductions in the use of acute and subacute mental health services and despite an increase in outpatient mental health services. There also was an observable impact on cost reductions in medical and criminal justice services without an increase in family costs over the same time period.

Depressive disorders: treatment patterns and costs of treatment in the private sector of the United States.

The purpose of this paper is to examine the treatment patterns and costs of treatment for depressive disorders in the private sector of the United States. Based on the 1987-1989 calendar year MEDSTAT claim data, 40,898 patients were identified with a principal diagnosis of depressive disorder. Among a list of CPT-4 code procedures, individual psychotherapy had the highest frequency of usage followed by individual visits. Compared to individual psychotherapy, group/family psychotherapy had a much lower frequency of usage. Very few diagnostic episodes had laboratory work. In inpatient settings, costs of physician procedures and laboratory services were 2 times greater for patients with major depression or bipolar disorder than for patients with depression not otherwise specified (NOS) or dysthymic disorder. As expected, costs varied widely per episode. As the severity of illness increased, the cost variation became wider.

Emergency care avoidance: ethnic matching and participation in minority-serving programs.

Using data from a county level mental health service system, relationships were examined between ethnic matching, program involvement and emergency service use. When clients were matched with an ethnically similar clinician who was also proficient in their preferred language, they had fewer emergency service visits than did clients who were unmatched on the basis of ethnicity and language. Equally if not more significant than ethnicity or language matching was the client's program and the proportion of minority clients it served. Clients in programs serving a relatively large proportion of minority clients had fewer emergency service visits than those in programs serving a smaller proportion of minority clients. More research is needed to document the impact of matching along with greater attention to minority oriented programs.

Long-term survival after intensive care unit admission with sepsis.

OBJECTIVE: To evaluate the long-term survival of critically ill patients with sepsis and to assess the factors predictive of long-term survival (> 1 month after admission date). DESIGN: Prospective, cohort study. SETTING: Medical/surgical intensive care unit (ICU) in a multidisciplinary community hospital. PATIENTS: All patients admitted to the ICU from January 1, 1987 to March 31, 1991 who both demonstrated clinical evidence of the systemic inflammatory response syndrome and yielded blood cultures positive for a bacterium or fungus (n = 153). INTERVENTIONS: Random set of procedures normally performed in an ICU setting. MEASUREMENTS AND MAIN RESULTS: Patient characteristics, including age, blood culture results, comorbid conditions, and severity of illness as estimated by the Acute Physiology Score of the Acute Physiology and Chronic Health Evaluation II prognostic system were recorded. Follow-up evaluation utilizing the National Death Index provided survival outcome for all patients 1 yr after hospital discharge. The mortality rate at hospital discharge was 51.0%, and mortality rates at 1 month, 6 months, and 1 yr after admission date were 40.5%, 64.7%, and 71.9%, respectively. A total of 33 patients survived beyond the period of observation. The analyses demonstrated the following findings: a) the survival rate was negatively correlated with the Acute Physiology Score up to 1 month after hospital admission date, but uncorrelated thereafter; b) fungal infections, such as Candida, had the shortest survival prospects of any blood-borne infection; and c) both malignancy and human immunodeficiency virus infection contributed to poorer outcomes, but differed in their patterns of long-term survival. CONCLUSIONS: The most critical period for surveillance of bacteremic patients was in months 2 through 6 after discharge, during which time, the percentage of patients surviving decreased dramatically. The degree of physiologic derangement, as measured by the Acute Physiology Score, was a useful measure of prognosis within the first month after the score was assessed at ICU admission. However, beyond this period, prognostic utility decreased significantly. Healthcare providers should use caution concerning the expected survival of hospitalized patients with human immunodeficiency virus, based on experience with distinct conditions, such as malignancies.

Reducing cigarette consumption in California: tobacco taxes vs an anti-smoking media campaign.

OBJECTIVES: The purpose of this study was to examine the relative effects of taxation vs an anti-smoking media campaign on cigarette consumption in California. METHODS: Quarterly cigarette sales data reported by the California State Board of Equalization between 1980 and 1992 were used to estimate a time-series model, adjusted for seasonal variations and time trends. RESULTS: The estimated results show that sales of cigarettes were reduced by 819 million packs from the third quarter of 1990 through the fourth quarter of 1992 owing to an additional 25-cent state tax increase, while the anti-smoking media campaign reduced the cigarette sales by 232 million packs during the same period. CONCLUSIONS: Both taxation and anti-smoking media campaigns are effective means of reducing cigarette consumption. The strength of those effects, however, is influenced by the magnitude of the taxes and the amount of media campaign expenditures.

Cost-effectiveness of substance disorder interventions for people with severe mental illness.

This study examines the cost effectiveness of three intervention strategies for people with severe mental illness who are dually diagnosed clients in terms of service use and costs. The interventions represent three primary approaches to treating these disorders: 12-step recovery, case management, and behavioral skills training. Interim findings from the study indicate that all three approaches are reducing acute and subacute service use and increasing involvement with outpatient and case management treatments. However, both the case management and behavioral skills approaches reduce costs more than the 12-step recovery approach, although not to a statistically significant degree in the data collected thus far. Overall, the societal costs for these clients are reduced by 43% without increasing the burden on client families or on the criminal justice system.

The hospital response to Medicare's Prospective Payment System: an econometric model of Blue Cross and Blue Shield plans.

This paper presents an empirical analysis of the impact that resulted from phase-in of Medicare's Prospective Payment System (PPS) on hospital utilization and payments for the Blue Cross and Blue Shield (BCBS) plans. A pooled cross-sectional time series econometric model was specified and estimated using quarterly hospital utilization and payments of the BCBS plans over the period 1980 to 1987. The results indicate that the implementation of PPS was significantly associated with a lower rate of hospital admissions, days and deflated inpatient payments for the BCBS plan members under age 65. A 1% increase in the proportion of hospital days reimbursed under PPS resulted in a .032% decrease in BCBS plan admissions per 1,000 members, a 0.017% decline in days per 1,000 members and a 0.016% decline in deflated inpatient payment per 1,000 members. The reductions in hospital utilization resulted in lower payments by BCBS plans to participating hospitals suggesting a positive spill-over effect of PPS for private insurers. This research underscores the importance of interaction between federal health policy and the private health insurance market.

The impact of California Proposition 99, a major anti-smoking law, on cigarette consumption.

In 1988, California voters enacted Proposition 99, increasing the tax on cigarettes by 25 cents per pack, effective January 1989. Monthly sales data reported by the California State Board of Equalization between 1984 and 1991, adjusted for seasonal variation and time trend, show that consumption of cigarettes in January 1989 was about 25 percent less than would have been expected in the absence of the tax. By December 1989 consumption was reduced to 9.5 percent below the pre-Proposition trend, an amount sustained throughout 1991. Additional taxation and a different form of taxation on cigarettes may further be considered.

Taxation, regulation, and addiction: a demand function for cigarettes based on time-series evidence.

This work analyzes the effects of prices, taxes, income, and anti-smoking regulations on the consumption of cigarettes in California (a 25-cent-per-pack state tax increase in 1989 enhances the usefulness of this exercise). Analysis is based on monthly time-series data for 1980 through 1990. Results show a price elasticity of demand for cigarettes in the short run of -0.3 to -0.5 at mean data values, and -0.5 to -0.6 in the long run. We find at least some support for two further hypotheses: that antismoking regulations reduce cigarette consumption, and that consumers behave consistently with the model of rational addiction.

The rise and decline of the Cooperative Medical System in rural China.

The Cooperative Medical System (CMS) in China is an established medical system that serves the rural areas and provides treatment and prevention of disease, immunization, family planning, and maternal and child health care services. Past experience suggests that the CMS benefited the peasants in rural China. During the 1980s, following reform of China's economic system, the CMS underwent major changes. In some places, CMS stations evolved into various other types of medical and health care systems; in other places, CMS stations ceased operation altogether. This article attempts to analyze the causes and meaning of these changes, and examines the conditions for continuation of this system.

Cost analysis for guideline implementation in prevention and early treatment of pressure ulcers.

One of the goals of the Agency for Health Care Policy and Research (AHCPR) is to improve the quality of medical care by developing and disseminating clinical practice guidelines. One indication of the effectiveness of a clinical guideline is the relationship between the costs of current practice and the costs of using the guideline. Using four model cases of patients at high risk for pressure ulcers, the costs of implementing the appropriate prevention and treatment procedures for each model were identified and compared to current practice costs. On the average, the overall cost of implementing the guideline is not much different from that of current practice.

Costs and use of public mental health services by ethnicity.

This paper used data obtained from Santa Clara County, California, to study the costs and use of public mental health services among ethnic populations (Asians, Blacks, Hispanics, and Whites). The study had access to 12,436 unduplicated users of services. The study found Whites had the highest per capita costs, while Asians incurred the lowest. However, after controlling for other demographic characteristics, Asians incurred higher costs than Whites. This reversal of Whites and Asians occurred because cost distributions are more skewed for Whites than Asians. Asians had the highest median costs and Hispanics the lowest. The top 5% of users incurred about 50% of the total public mental health costs.

HMO and PPO growth and hospital utilization and payment: a recursive model.

A recursive model of growth of Blue Cross and Blue Shield Plan Health Maintenance Organization (HMO) and Preferred Provider Organization (PPO) membership share is used to analyze total hospital utilization and payments per thousand insured members over an eight year study period, 1980 through 1987. Results indicate a strong, significant relationship between previous year Plan payments and current year growth in HMO membership share. Additional results suggest that Blue Cross and Blue Shield Plans experienced significant reductions in utilization and payments rates resulting from PPO membership share gains and not from HMO membership share gains.

Association between formulary strategies and hospital drug expenditures.

National survey data were analyzed to determine whether an association existed between formulary strategies and hospital drug expenditures. Data on community hospitals were obtained from (1) ASHP's 1987 national survey of pharmaceutical services, (2) the American Hospital Association, and (3) the Health Care Financing Administration. Along with size, case mix, and salary information, data were collected on whether the hospitals used a well-controlled formulary, whether they used therapeutic interchange, and how much money they spent on drugs. A logarithmic cost-function model was used to obtain a straight-line equation that expressed the relationships between drug cost per patient day and the other variables assessed. Summary statistics were calculated with data from 514 hospitals. The adjusted coefficient of multiple determination indicated that the model was able to explain 24.6% of the observed variation in drug cost per patient day. A significant association was found between decreased costs and a well-controlled formulary, therapeutic interchange, or both. Hospitals that used either strategy spent 10.7% less for drugs than those that used neither. Hospitals that used both strategies spent 13.4% less than those that used neither. Analysis of national survey data suggests that use of a well-controlled formulary, therapeutic interchange, or both are associated with lower pharmacy drug expenditures.

Simple urodynamic evaluation of incontinent elderly female nursing home patients. A descriptive analysis.

We present a descriptive analysis of the functional, mental, and urodynamic status of a population of incontinent elderly female nursing home patients. One hundred fifty-five intermediate care female patients with a mean age of 85.5 years were identified as being incontinent of urine at least once daily. After urologic evaluation, each patient was classified into one of four categories: incontinence with normal cystometrogram 68 (44%), detrusor instability (DI) 52 (34%), stress incontinence (SI) 27 (17%), or overflow incontinence (OI) 7 (4%). Thirteen weeks later, patients were again studied using simple water cystometry. At follow-up evaluation, 45 patients (33%) had urodynamic findings which differed from the initial evaluation. Of these women, 10 with DI, 12 with SI, and 2 with OI were found to have normal cystometric parameters at the time of follow-up study, while 19 (14%) who initially had normal cystometric findings had evidence of DI (11) or SI (3). Strong correlation between urinary incontinence in patients with normal cystometric findings and moderate to severe cognitive impairment was present. Simple urodynamic evaluation did identify patients with SI and OI who might benefit from specific therapy. Urodynamic evaluation of incontinent elderly female nursing home patients is indicated and may provide direction for planning treatment strategies.

Medical technology transfer in major Chinese hospitals.

The objective of this article is to describe and analyze the decision-making process and its consequences for medical technology transfer in China. Data were obtained in 1987 from 35 elite teaching hospitals affiliated with 13 medical universities, directly supervised by the Ministry of Health in the People's Republic of China. This article focuses on three kinds of diagnostic equipment: computerized tomographs, ultrasonic diagnostic units, and high-power x-ray diagnostic apparatuses. Decision-making on the transfer of medical technology in China is decentralized. Most hospitals rely on foreign medical sales representatives and medical exhibits, and their decisions on the acquisition of equipment rely more on the services available than on the price of the product. Chinese hospitals also encounter serious infrastructure problems when buying medical equipment. A number of alternatives are suggested for improving the efficiency of medical technology transfer in China.
