Does publishing the parameters that trigger review of Medicare claims change provider behavior? Results of the parameter release study.

In April 1989, the Health Care Financing Administration stopped publishing the parameters that trigger review of Medicare claims because they thought that knowledge of the parameters would permit providers to schedule visits to avoid review. In this article, the authors report the results of an experimental study where previously unrevealed parameters were revealed to some providers of Medicare services and not to others. The authors find little evidence to suggest that providers schedule procedures to avoid review when they know the parameters. There is some evidence, however, that providers may be responding to the release of the parameters in other ways.

Urban/rural differences in home health patients and services.

Using data from the Wisconsin Annual Survey of Home Health Agencies, we describe urban/rural differences for home health care patients. Our findings indicate that urban dwellers are more likely to be home health patients than are rural residents. Urban home health patients are more apt to be nonelderly, male, and have "other conditions" as their primary diagnosis. They are also likely to be more physically dependent and to receive home care longer. Urban home health patients are more typical of long-term care patients, whereas rural patients may be better described as recipients of postacute care, often recovering from diabetes and heart attacks. Possible problems with rural access to home health care are discussed.

Adult foster care for the elderly in Oregon: a mainstream alternative to nursing homes?

BACKGROUND: In Oregon, adult foster care (AFC) homes, which are private residences where a live-in manager cares for one to five disabled residents, have been covered by Medicaid since 1981 and seem to offer a mainstream alternative to nursing homes. They house almost 6000 older people, two thirds of which pay privately. METHODS: In a cross-sectional study, we interviewed 400 AFC and 400 nursing home residents. Data analyses included descriptive cross-tabulations; hierarchial loglinear models for judging the effects of care setting and payment status on resident characteristics; and logit analyses for predicting care setting and payment status within care settings. RESULTS: On average, nursing home residents were more physically and cognitively impaired than AFC residents, but there was considerable overlap in patterns of frailty in the two settings. Medicaid AFC residents were less disabled than privately paying AFC residents. AFC residents reported more social activity, even when we controlled for disability status. AFC residents and their families were more likely to value privacy and homelike settings when choosing a care setting, whereas nursing home residents were more likely to value rehabilitation and organized activity programs. CONCLUSIONS: Both AFC and nursing homes are viable components of a long-term care repertoire. The greater disability levels of private-pay AFC residents refutes the criticisms that disabled Medicaid residents were being inappropriately channeled to AFC.

Changing physician behavior: does medical review of Part B Medicare claims make a difference?

This study attempts to determine whether the implementation of mandatory review of Medicare Part B claims for medical necessity has resulted in physicians submitting fewer medically unnecessary claims. After summarizing the literature on the effectiveness of various methods for changing physician practices, we compare the rate at which physicians submitted medically unnecessary claims before and after HCFA imposed mandatory review screens. We find that, consistent with expectations from the literature, the screens are only marginally effective (at best) in reducing the rate at which medically unnecessary claims are submitted. We make some suggestions for lowering this rate.

The ratio of impaired elderly in the community to those in nursing homes in two rural Iowa counties.

The Iowa 65+ Rural Health Study gathered health status information on all elderly persons living in two rural Iowa counties. In this report these data are used to determine the ratio of persons with activities of daily living (ADL) dependencies living in the community to those in institutions. Results indicated that the "community/institutional dependency ratio" is about 1 to 1 for these counties, which is about half the ratio representing conventional wisdom. Possible explanations for this difference are discussed. In addition, it was found that the level of ADL dependency (need) can serve alone as an almost certain predictor of institutionalization for some elderly. For others, ADL dependency (need) is only one factor. The likely variability of the community/institutional dependency ratio across different geographic areas has implications for government funding of home health care, for long-term care insurance, and for eliminating excess demand. These implications are discussed.

Promoting the quality of life in nursing homes: can regulation succeed?

It has been assumed that the best policy for promoting quality of life in nursing homes is direct regulation. In this paper it is argued that if our experience in regulating quality of care is any indication, we may not possess the political will to successfully regulate quality of life. Moreover, from a legal perspective, the less concrete nature of the concept of quality of life may make it more difficult to regulate than quality of care. Finally, although regulation would probably be necessary if potential nursing home residents (and their agents) lacked the information or rationality to make choices that promoted their interests, this has never been shown to be the case empirically. Therefore, we may not be forced to choose regulation to achieve an adequate quality of life. Alternative--and perhaps better--policies may be available.

Excess demand, consumer rationality, and the quality of care in regulated nursing homes.

This article investigates whether an empirical basis exists for the hypothesis that nursing homes exploit the irrationality of some nursing home patients by providing inadequate quality care. Evidence from Wisconsin in 1983 shows that violations of the Medicaid certification code in nursing homes are not statistically related to two measures of consumer rationality. Violations are, however, related to a measure of the need to compete for patients, despite the presence of an effective program to enforce these certification standards through fines. Specifically, it is found that, where the bed supply is tight, an additional empty bed in every nursing home in a county is associated with between five and six fewer class C violations (or their equivalent) in every home. This evidence is consistent with the hypothesis that the quality problems that nursing homes have traditionally exhibited are linked to the absence of a need to complete for patients, created by the bed shortage conditions that continue to characterize a large portion of nursing home care markets in the United States. The implications for public policy are discussed.

Analysis of nursing home use and bed supply: Wisconsin, 1983.

This article presents evidence that in 1983 excess demand was a prevailing characteristic of nursing home care markets in Wisconsin, a state with one of the highest bed to elderly population ratios. It further shows that excess demand is the source of at least three types of error in use-based estimates of the determinants of the need for nursing home care. First, if excess demand is present, estimates of the determinants of Medicaid use may simply represent a crowding out of Medicaid patients, driven by the determinants of private use. As a result, factors associated with greater overall need in an area will be correlated with fewer Medicaid patients in nursing homes, ceteris paribus. Second, estimates of the substitutability of home health care for nursing home care may be misleadingly insignificant if they are based on the bed supply-constrained behavior of Medicaid-eligible subjects. Third, because the determinants of bed supply become the determinants of overall use under excess-demand conditions, the determinants of use will reflect, to some extent, the nursing home's desire for profits. Because profitability considerations are reflected in use based estimates of need, these estimates are likely to be misleading.

Improving the quality of nursing home outcomes. Are adequacy- or incentive-oriented policies more effective?

Recent debates over health policy have tended to be between procompetitive solutions and proregulatory ones. This dichotomy, however, seems to be less descriptive of the policy debate over ways to improve nursing home quality. This article argues that a more useful distinction may be between adequacy- and incentive-oriented policies. The nursing home industry and others have argued that the financial and physical resources at the disposal of nursing homes have been inadequate to produce acceptable quality levels. Whether quality requires more resources is tested using the 1983 Iowa Outcome Oriented Survey, but none of the quality measures constructed from these data were significantly associated with higher average costs. On the other hand, nonprofit nursing homes, nursing homes with more professional workers (nurses), and nursing homes that cater to private patients have incentives that may motivate them to provide better quality. These factors were often significantly associated with a variety of the quality measures, suggesting that policies based on incentives may be more effective than adequacy-oriented policies.

Home blood transfusions: the medical, economic, and legal issues surrounding a new treatment procedure.

Blood transfusions have almost always been confined to hospital settings in the past. Recent medical care trends have shifted some therapies (e.g., renal dialysis, hemophilia treatment) into the patient's home. Transfusions are now being given in increasing numbers to stable patients in their homes. This paper examines the medical aspects, the economic issues, and the legal implications of such transfusions. Candidates for home transfusion must be carefully chosen primarily according to the medical guidelines for such treatment. Any legal issues must be satisfactorily answered before approval is given. The paper concludes that if done properly, home transfusions can be safe, cost-effective, and convenient for a carefully selected segment of patients.

The effect of competition on nursing home expenditures under prospective reimbursement.

The for-profit nursing home's incentive to minimize costs has been maligned as a major cause of the quality problems that have traditionally plagued the nursing home care industry. Yet, profit-maximizing firms in other industries are able to produce products of adequate quality. In most other industries, however, firms are constrained from reducing costs to the point where quality suffers by the threat of losing business to competing firms. In the nursing home industry, competition for patients often does not exist because of the shortage of nursing home beds. As a result, one would expect that nursing homes located in areas where there is excess demand would spend less on patient care than homes located where the bed supply is relatively abundant. This hypothesis is tested using Wisconsin data from 1983. It is found that, in counties with relatively tight bed supplies, an additional empty bed in all the homes in the county will force each home to increase expenditures by $.62 per day for each patient in the home. Overall, the average nursing home located in underbedded markets would spend $5.12 more per patient day or about $240,000 more annually (in 1983 dollars) if it were located in a market where it was forced to compete for patients. The implications for public policy are discussed.

RUGs and equity of access to nursing home care.

Case-adjusted prospective reimbursement systems, such as resource utilization groups (RUGs), may promote nursing home cost containment, but they may do no better than existing systems at encouraging homes to admit the more dependent and thus costlier Medicaid patients, if the homes' reluctance to admit these patients is due to a shortage of nursing home beds. Using 1983 data on Wisconsin nursing homes, this paper presents evidence that suggests that the presence of excess demand, rather than low reimbursement rates, causes nursing homes to exclude the more costly Medicaid patients. Consequently, to benefit fully from RUGs, it is necessary either to eliminate excess demand (by increasing supply or decreasing demand) or to decide which patients have priority for admission and assign reimbursement payments to these patients that significantly favor these patients. Otherwise, access to nursing home care under RUGs is left to chance.(ABSTRACT TRUNCATED AT 250 WORDS)

Does the average cost of home health care vary with case mix?

The relationship between the average cost of home health care and the case mix of patients served by the home health agency is investigated using 1983 data from Wisconsin's home health care agencies. In contrast to previous work, case mix is shown to have a significant effect on the home health agency's average costs. The methods used in the previous work are evaluated, and differences between the earlier study and the present study are discussed to explain the divergent results. Also, average costs are shown to decrease with output, to increase with the proportion of private patients served by the agency, and to be higher if the home health agency is located in an urban area or if it has a proprietary charter. The implications of this research for the design of an appropriate home health reimbursement policy are discussed. Primarily, it is argued that, although future research might confirm the relationship between average costs and case mix for home health agencies, we cannot necessarily conclude that reimbursement rates must be adjusted to account for differences in case mix as many States are now doing for nursing home reimbursement. Policies must take into account the fundamental differences between home health agencies and nursing homes, and their respective markets, in order to be effective.
