Validation of a pneumonia prognostic index using the MedisGroups Comparative Hospital Database.

PURPOSE: Our purpose was to validate a previously developed pneumonia-specific prognostic index in a large, multicenter population. PATIENTS AND METHODS: We developed a pneumonia-specific prognostic index in a prospective, multicenter study of 346 patients with clinical and radiographic evidence of pneumonia admitted to 3 Pittsburgh hospitals (the derivation cohort), and validated the index in 14,199 patients with a principal ICD-9-CM diagnosis of pneumonia admitted to 78 hospitals in the 1989 MedisGroups Comparative Hospital Database (the validation cohort). The prognostic index classified patients into five ordered risk classes based on six predictors of mortality: age greater than 65 years, pleuritic chest pain, a vital sign abnormality, altered mental status, neoplastic disease, and high-risk pneumonia etiology. Each patient in the validation cohort was assigned to a risk class by obtaining values for the index's six predictors in the MedisGroups population. The performance of the prognostic index in the derivation and validation cohorts was assessed by comparing hospital mortality rates within each of the index's five prognostic risk classes. RESULTS: The hospital mortality rate was 13.0% in the derivation cohort, and 11.1% in the validation cohort (p = 0.26). The agreement in the risk class-specific mortality rates was striking with the exception of class V: in class I, mortality was 0% in the derivation cohort versus 1% in the validation cohort; in class II, 0% versus 1.1%; class III, 10.9% versus 8.6%; class IV, 21.8% versus 26.2%; and class V, 73.7% versus 37.7%. There were no statistically significant differences in mortality rates within the first four risk classes, which represented the vast majority of patients in the derivation (94%) as well as the validation (98%) cohorts. CONCLUSIONS: These data support the generalizability of a pneumonia-specific prognostic index. This index, which performs exceptionally well in classifying low-risk patients, may help physicians identify patients with community-acquired pneumonia who could safely be managed in the ambulatory setting, or if hospitalized, the patients that could be treated with abbreviated inpatient care.

The attitudes of Ontario hospitals toward transitional funding: response to a survey.

A survey of hospital administrators throughout Ontario was conducted to determine their views about the strengths and weaknesses of the new Transitional Funding system, especially as it existed between Phase One and Phase Two when many changes were taking place. The basic findings of the survey are presented. The authors go on to explore some of the answers and determine whether the hospital's responses were influenced by their participation in the process and whether they were "winners" or "losers" as a result of the changes. This type of information should be useful to policy makers in Ontario as they modify the overall hospital financial system, and also be useful to policy makers outside the province who are contemplating making such changes.

Comparison of recruitment strategies and associated disease prevalence for health promotion in rural elderly.

BACKGROUND: Although interest in health promotion for the elderly is increasing, the issues of recruitment into such programs and self-selection have not been well explored. While clinical studies require high participation levels and expensive recruitment, community efforts are satisfied with recruiting small numbers of volunteers from poorly defined populations. These small samples may not be representative of the populations at risk. METHODS: As part of the Rural Health Promotion Project, a Medicare demonstration, community-based recruitment methods were evaluated and participant characteristics were compared. A total of 3,884 individuals ages 65-79 were recruited in northwestern Pennsylvania, using four sequential recruitment strategies, varying in aggressiveness. The methods were: (A) mail only, (B) mail with phone recruitment follow-up, (C) mail with phone recruitment and scheduling, and (D) mail with aggressive phone recruitment and scheduling. RESULTS: Recruitment yields were Method A, 13.5%; B, 21.1%; and C, 31.6%. The most aggressive Method (D) yielded 37.0% participation. More aggressive methods (C and D) recruited more educated individuals. No other demographic or health status differences were noted. CONCLUSION: These data show that large numbers of the elderly can be recruited into a health promotion program using aggressive methods and professional interviewers.

Alberta's Acute Care Funding Project.

Alberta initiated the Acute Care Funding Project (ACFP) in 1988, a new hospital funding system that institutes case mix budgeting adjustments to the global budget so that hospitals can be treated more equitably. The initiative is a significant departure in principle from the former method of funding. The ACFP is summarized and critiqued, and focuses on the inpatient side of the picture. The various elements of the project are discussed, such as the hospital performance index, the hospital performance measure, the Refined Diagnostic Related Group, case weights, typical and outlier cases, and the costing mechanisms. Since its implementation, the ACFP has undergone substantial changes; these are discussed, as well as some of the problems that still need to be addressed. Overall, the system offers incentives to reduce length of stay and to increase the efficiency with which inpatient care is provided.

Transitional funding: changing Ontario's global budgeting system.

In 1988, Ontario introduced transitional funding, a collaborative process between the Ministry of Health and the hospitals to modify Ontario's global budgeting system. The goals are to achieve greater equity; encourage hospital efficiency, and promote a shift from inpatient to outpatient services. To implement these goals, inpatient care is being measured in terms of case-mix groups, i.e., a classification system comparable to the diagnosis-related groups. However, since there is no patient level cost data, cost weights are being derived from patient-level data from New York State. Transitional funding draws attention to both positive and negative aspects of global budgeting.

A method for assessing the impact of a computer-based decision support system on health care outcomes.

The wide variation in utilization of diagnostic resources has not been decreased by the proliferation of new diagnostic technologies. We wish to test the hypothesis that the introduction of a medical decision support system into clinical practice could potentially lead to more efficient use of diagnostic information, and therefore lead to a reduction in overall laboratory use and cost of care. We have devised and are currently implementing a randomized controlled trial of a computer based decision support system, the University of Pittsburgh version of Quick Medical Reference (QMR). The main purpose of the study is to determine the effect of the QMR program on specific outcome measures: length of hospital stay, number and types of diagnostic tests ordered, and overall charges. An important part of this evaluation is relating the initial level of diagnostic uncertainty expressed by the admitting housestaff team to utilization of diagnostic resources. The purpose of this paper is to describe the methodology for carrying out this controlled trial, and to describe our initial experiences with its implementation.

Ontario's hospital transitional funding initiative: an overview and assessment.

In 1989, the hospital transitional funding initiative, which incorporates case mix measurement into the hospital funding process, was started in Ontario. This initiative is the beginning of a new, more objective basis for determining hospital funding. In its initial stages, incremental growth and interhospital equity adjustments are made to the global budgets. In this paper, we describe the launching of this initiative and the funding formulas that emerged from its first phase. The issue of incentive effects is then discussed and, as this is an evolving or "transitional" undertaking, we comment on several economic issues arising as a result of this new venture.

Effect of the structure of hospital payment on length of stay.

In response to rapidly rising costs, payers for health care services have made a number of changes in the way they reimburse hospitals for care. In this article we study the effect of different payment methods on the length of stay of Medicaid patients. We examine supply response by type of patient (medical, surgical, and psychiatric) and hospital ownership. We find that per case payment systems and negotiated contracts lead to significant decreases in the length of stay for all groups. Prospective per diem with limits in most cases leads to decreases in the length of stay. In general, we find that the supply response is stronger for psychiatric patients than for medical and surgical patients, and that publicly owned hospitals are more responsive to payment system incentives than are nonpublic hospitals.

A comparison of hospital responses to reimbursement policies for Medicaid psychiatric patients.

Hospital expenditures continue to increase at rates that are higher than that of GNP growth. Policymakers are experimenting with a number of reimbursement methods in an attempt to curtail the growth in hospital costs. This article empirically assesses the impact of various hospital reimbursement methods on the use of hospital services. We specified and estimated a model of hospital duration for Medicaid psychiatric patients. A new semiparametric approach to estimation was implemented for a large national sample of hospital discharges. The empirical findings show significant reductions in hospital duration are associated with per case prospective payment as compared with cost-based reimbursement.

The decision to seek an exemption from PPS.

This paper examines the receipt of exemptions from Medicare's Prospective Payment System (PPS) for distinct part psychiatric units of general hospitals. A logit model of the exemption status of 1,045 psychiatric units is estimated using 1984 data. The results suggest that units that were expected to profit from a change in payment method (cost based on PPS) were least likely to obtain an exemption from PPS.

Psychiatry under prospective payment: experience in the first year.

The authors present data on changes in resource use by Medicare psychiatric patients in general hospitals after the introduction of the prospective payment system in 1984. Length of stay and charges per discharge during fiscal year 1984 fell 13.8% and 15.9%, respectively, after the new system began, even though 31.8% of the discharges for Medicare psychiatric cases were from exempt psychiatric units. The decrease in length of stay was considerably larger (23.2%) in hospitals with no psychiatric units, which were not exempt from prospective payment.

Factors affecting Medicaid patients' length of stay in psychiatric units.

The structure of the Medicaid program varies widely among the States. Examined in this article is the relationship between certain characteristics of the State Medicaid programs and the length of stay of patients who are discharged from psychiatric units in general hospitals. It has been found that setting limits on the number of reimbursable days leads to shorter lengths of stay and that, after controlling for region, length of stay is not influenced by utilization review or State rate setting.

The early effects of Medicare's prospective payment system on psychiatry.

In this paper, we study the effects on psychiatry of Medicare's prospective payment system (PPS) during 1984, as PPS was implemented. We examined data on psychiatric discharges before and after PPS from three kinds of hospitals--those with psychiatric units exempt from PPS, those with nonexempt units, and those that treated psychiatric patients in scatter beds--as well as data on all hospital discharges. We conclude that the providers of psychiatric services responded to the incentives inherent in PPS much the way hospitals as a whole did--with significantly reduced lengths of stay. Of the three kinds of hospitals that rendered psychiatric care, those that treated patients in scatter beds had the greatest reduction in length of stay. Using readmission rates as a gross indicator of quality, we conclude that quality did not suffer because of the shortened stays.

Financing graduate medical education and biomedical research: whose responsibility?

In the United States, biomedical research and graduate medical education are particularly vulnerable in the current era of prospective payment and price competition. Traditionally these services have been financed through the cross-subsidization of patient care dollars, and this practice cannot continue in the current economic environment. This paper reviews the various options for financing these services and makes several specific recommendations.
