We've collected the OASIS data, now what?

The OASIS data set provides home care agencies with well-tested items for the collection of patient health status and outcome data. Illustrative examples of some of the OASIS-derived reports that agencies participating in demonstration projects received are presented. By understanding these reports, clinicians can see how the information they collect is presented in reports and can better understand the importance of collecting complete and accurate data.

Outcome-based quality improvement in home health care: the OASIS indicators.

The outcomes movement in home health care is expanding rapidly, with strong support from both the industry and Medicare. The Federal government has proposed requiring all Medicare-certified agencies to collect data items from the Outcome and Assessment Information Set (OASIS) to form the basis for standardized risk-adjusted outcome reporting as part of a systematic outcome-based quality improvement (OBQI) approach. In addition to contributing to improving patient outcomes, OASIS data items, when combined with other assessment information, utilization data, and cost information, can provide home health care agencies with a powerful integrated information set for internal management and strategic planning.

Outcomes across the care continuum. Home health care.

OBJECTIVES: This article describes one approach to measuring outcomes across the continuum of care. METHODS: Development and testing of the outcome-based quality-improvement methodology as developed by the University of Colorado Center for Health Services Research in Denver, Colorado are summarized. RESULTS: Reliable and valid measures for home health care covering end results (pure outcome), intermediate results (instrumental outcome), and use (proxy outcome) were developed and are useful in demonstrating patient improvement or stabilization as well as decline. Further, these measures can be aggregated by agency and, with appropriate severity or risk adjustment, can be used to compare outcomes over time and across agencies. CONCLUSIONS: National testing of the methodology is currently ongoing, with refinements underway in measures, risk adjustment, and operational implementation.

Home care: moving forward with continuous quality improvement.

The utility of examining the effectiveness of home care is illustrated by selected examples and applications. The growth rate of home care over the past decade, questions regarding the possibly substantial differences between the quality of home care in rural and urban America, and empirical evidence that suggests inferior quality of home care for health maintenance organization patients support the need for measuring and monitoring outcomes of home care. The conclusions of a research program targeted at developing a system of outcome measures for home care, and the resulting national demonstration program to implement and refine that system, are summarized.

Case mix of home health patients under capitated and fee-for-service payment.

OBJECTIVE: We compare case mix of Medicare home health patients under HMO and FFS payment. STUDY DESIGN: A pseudo-experimental design was employed to study case mix using three types of Medicare-certified home health agencies (HHAs): HMO-owned agencies, pure FFS agencies that admit few Medicare HMO patients (less than 5 percent of admissions are Medicare HMO patients), and mixed (or contractual) agencies that admit at least 15 Medicare FFS patients and 15 Medicare HMO patients per month. SAMPLES OF PROVIDERS AND PATIENTS: Random samples of Medicare-aged patients (> or = 65 years) were selected at admission between June 1989 and November 1991 from the 38 study HHAs. Sample sizes by agency type were: 308 patients from 9 HMO-owned agencies; 529 patients from 15 pure FFS agencies; and 381 HMO patients and 414 FFS patients from 14 contractual agencies. DATA: Primary longitudinal data were prospectively collected at admission for all patients on health status indicators, demographics, admission source, and home environment. MEASURES: The most important case-mix measures were functional and physiologic indicators of health status, including (instrumental) activities of daily living ([I]ADLs). Selected indicators of demographic variables, prior location, living situation, characteristics of informal caregivers, mental/behavioral factors, and resource needs were also used. PRINCIPAL FINDINGS: (a) The case mix of Medicare FFS patients compared with Medicare HMO patients was more intense in terms of impairments in ADLs, IADLs, and various physiologic conditions. Pressure ulcers as well as neurological and orthopedic impairments requiring rehabilitation care were also more prevalent among FFS patients. (b) Relative to HMO patients admitted to contractual agencies, HMO patients admitted to HMO-owned agencies were moderately more dependent in ADLs and IADLs. However, only 62 percent of HMO patients admitted to HMO-owned agencies, in contrast to 77 percent of HMO patients admitted to contractual agencies, had been hospitalized during the 30 days prior to home health admission. (c) In all, the case mix of patients receiving care from HMO-owned agencies is more heterogeneous than the case mix of HMO patients receiving care from contractual agencies. CONCLUSIONS: The case-mix (and selected utilization) findings indicate that HMOs use home health care differently than does the FFS sector. The greater diversity of case mix for HMO-owned agencies and the narrower or less diverse case mix that characterizes HMO patients receiving home care on a contractual basis point to the likelihood of cost differences among the two types of HMO patients and FFS patients, and raise the question of possible outcome differences.

Analytic framework for evaluation of telemedicine.

This paper discusses two conceptual models intended to facilitate research on the effects and effectiveness of telemedicine. The first is a conceptual framework to study the efficacy of telemedicine as a diagnostic medium. Using conditions that are carefully chosen to serve as indicators of effectiveness, we recommended the analysis of sensitivity and specificity to establish the accuracy of telemedicine in relation to conventional health care delivery. Suggested guidelines for interpretation of the results are discussed. The second model is a scheme for classification of telemedicine applications that is based on processes of care rather than on specialties or disorders. The purpose of this classification scheme is to facilitate research on such variables as costs, access, acceptability, and effects on practice patterns.

Patient-level cost of home health care under capitated and fee-for-service payment.

This article examines costs for a national sample of 1,260 Medicare patients receiving home health care from 38 home health agencies. It uses data from a study that compares home health care provided to Medicare beneficiaries in health maintenance organizations (HMOs) and the traditional fee-for-service (FFS) system. The major findings indicate significantly lower costs, based on fewer home health visits, for HMO patients compared to FFS patients, even after adjustment for case mix and other factors. However, FFS patients also attain better outcomes, suggesting that HMOs may provide too few visits to home health patients. At the same time, the number of visits to FFS patients may be greater than is necessary to achieve the better FFS outcomes.

Outcome-based quality improvement in home care.

A system of outcome measures of service quality was developed and tested. The findings of this project will provide a framework for moving forward with outcome-based quality improvement in home care. Using outcome measures will permit agencies to analyze their performance in terms of effectiveness of care.

Quality of care in teaching nursing homes: findings and implications.

This article explores policy implications and selected methodological topics relating to long-term care (LTC) quality. We first discuss the Teaching Nursing Home Program (TNHP), in which quality of care in teaching nursing homes (TNHs) was found to be superior to the quality of care in comparison nursing homes (CNHs). A combination of outcome and process/structural measures was used to evaluate the effects of care and underlying reasons for superior TNH outcomes. Second, we explore policy and analytic ramifications. Conceptual, methodological, and applied issues in measuring and improving the quality of LTC are discussed in the context of TNH research and related research in home care.

Effects and effectiveness of telemedicine.

The use of telemedicine has recently undergone rapid growth and proliferation. Although the feasibility of many applications has been tested for nearly 30 years, data concerning the costs, effects, and effectiveness of telemedicine are limited. Consequently, the development of a strategy for coverage, payment, and utilization policy has been hindered. Telemedicine continues to expand, and pressure for policy development increases in the context of Federal budget cuts and major changes in health service financing. This article reviews the literature on the effects and medical effectiveness of telemedicine. It concludes with several recommendations for research, followed by a discussion of several specific questions, the answers to which might have a bearing on policy development.

Home health care outcomes under capitated and fee-for-service payment.

In this article, case-mix-adjusted outcomes of home health care are found to be superior for Medicare fee-for-service (FFS) patients relative to Medicare health maintenance organization (HMO) patients. The superior outcomes for FFS patients were accompanied by higher utilization and cost of home health services, suggesting a volume-outcome (or dose-response) relationship that was further substantiated by within-HMO and within-FFS analyses. The findings suggest that greater attention should be paid to both outcome-based quality assurance and managed care practices that may be overly restrictive in terms of the use of home health services.

Measuring and assuring the quality of home health care.

The growth in home health care in the United States since 1970, and the exponential increase in the provision of Medicare-covered home health services over the past 5 years, underscores the critical need to assess the effectiveness of home health care in our society. This article presents conceptual and applied topics and approaches involved in assessing effectiveness through measuring the outcomes of home health care. Definitions are provided for a number of terms that relate to quality of care, outcome measures, risk adjustment, and quality assurance (QA) in home health care. The goal is to provide an overview of a potential systemwide approach to outcome-based QA that has its basis in a partnership between the home health industry and payers or regulators.

Medicare home health reimbursement alternatives: access, quality, and cost incentives.

This paper presents a conceptual analysis of access, quality, and cost containment incentives created by several current and potential Medicare reimbursement methodologies. The alternatives examined are methods used by health maintenance organizations (HMOs) and three options receiving national policy consideration: prospective per-visit and per-episode payment, and "bundling." The analysis found better incentives (from a policy perspective) for HMOs with integral home health units than for HMOs using outside contractors. Of the other options, per-episode payment appeared most promising, but requires accurate case mix adjustments. All approaches also require quality assurance tailored to reimbursement incentives. Topics for further research and demonstrations are suggested.

Quality of long-term care in nursing homes and swing-bed hospitals.

By 1989, more than 1,100 hospitals in rural communities throughout the United States were using hospital beds as swing beds to provide both long-term and acute care. In this study, the quality of long-term care in swing-bed hospitals was compared with the quality of nursing home care, using patient outcomes along with both process and structural measures of quality. Several methodological and conceptual points on measuring and analyzing the quality of long-term care are discussed in this article. Data were analyzed on approximately 2,000 patients in four different primary data samples, three of which were longitudinal involving multiple follow-up points. An analysis of changes in patient status over time, hospitalization rates, rates of discharge to independent living, services provided, and certain structural indicators showed that (1) relative to nursing home care, swing-bed care is more effective in enhancing functional outcomes and discharge to independent living and in reducing hospitalization for long-term care patients, and (2) nursing home care appears more desirable than swing-bed care for long-stay, chronic care patients with no rehabilitation potential. Swing-bed hospitals have gravitated largely to admitting postacute long-term care patients. They do not typically compete directly with community nursing homes for chronic care patients. The greater effectiveness of swing-bed care for patients with near-acute long-term care needs suggests that this approach should be considered in urban communities and that we should scrutinize our current tendency to place in traditional nursing homes many patients who have at least some rehabilitation potential.

The increased needs of patients in nursing homes and patients receiving home health care.

To evaluate the effects of Medicare's prospective payment system and Medicaid's preadmission regulations on long-term care, we constructed clinical profiles in 1982 and 1986 of about 500 randomly selected patients from each of three types of facilities: nursing homes with relatively high proportions of Medicare patients (high-Medicare nursing homes; n = 23), traditional nursing homes (n = 19), and home health agencies (n = 18). Data were obtained directly from the care givers on the medical problems, problems requiring skilled nursing, and functional problems of these representative patients from 12 states. For Medicare patients in high-Medicare nursing homes, the prevalence of medical problems and problems requiring skilled nursing increased substantially, whereas the prevalence of functional problems remained relatively unchanged. For example, from 1982 to 1986 there was a marked increase in the frequency of tube feedings (21 to 29 percent), oxygen use (6 to 14 percent), urinary tract infection (7 to 13 percent), and diastolic hypertension (1 to 10 percent), but not difficulty in eating (48 to 51 percent) or speaking (28 to 29 percent). In contrast, in traditional nursing homes there was an increase in the prevalence of functional disability, but virtually no change in that of problems requiring medical and skilled nursing care. In home health care the functional care needs of Medicare patients increased significantly, and there was a slight increase in the prevalence of problems requiring medical and skilled nursing care. We conclude that from 1982 to 1986 the needs of patients in long-term care increased substantially. This trend appears to result from Medicare's prospective payment system, which encourages earlier hospital discharge to long-term care settings, and from Medicaid's policy of de-institutionalization. Meeting this greater need for care will be costly. We require a better system of reimbursing for long-term care and ensuring its quality.
