How Much Is Postacute Care Use Affected by Its Availability?

HEALTH SERVICES RESEARCH, Issue 2 2005
Melinda Beeuwkes Buntin
Objective. To assess the relative impact of clinical factors versus nonclinical factors,such as postacute care (PAC) supply,in determining whether patients receive care from skilled nursing facilities (SNFs) or inpatient rehabilitation facilities (IRFs) after discharge from acute care. Data Sources and Study Setting. Medicare acute hospital, IRF, and SNF claims provided data on PAC choices; predictors of site of PAC chosen were generated from Medicare claims, provider of services, enrollment file, and Area Resource File data. Study Design. We used multinomial logit models to predict PAC use by elderly patients after hospitalizations for stroke, hip fractures, or lower extremity joint replacements. Data Collection/Extraction Methods. A file was constructed linking acute and postacute utilization data for all medicare patients hospitalized in 1999. Principal Findings. PAC availability is a more powerful predictor of PAC use than the clinical characteristics in many of our models. The effects of distance to providers and supply of providers are particularly clear in the choice between IRF and SNF care. The farther away the nearest IRF is, and the closer the nearest SNF is, the less likely a patient is to go to an IRF. Similarly, the fewer IRFs, and the more SNFs, there are in the patient's area the less likely the patient is to go to an IRF. In addition, if the hospital from which the patient is discharged has a related IRF or a related SNF the patient is more likely to go there. Conclusions. We find that the availability of PAC is a major determinant of whether patients use such care and which type of PAC facility they use. Further research is needed in order to evaluate whether these findings indicate that a greater supply of PAC leads to both higher use of institutional care and better outcomes,or whether it leads to unwarranted expenditures of resources and delays in returning patients to their homes.

An assessment of consumer preference for fair trade coffee in Toronto and Vancouver

AGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 2 2010
John Cranfield
In this article, the authors use conjoint analysis to elicit the views of coffee consumers on the attributes of Fair Trade coffee using data from the Greater Toronto Area and Vancouver collected through face-to-face interviews with consumers. The impact of socioeconomic and demographic factors on respondents' acceptance of Fair Trade coffee is evaluated using cluster analysis and multinomial logit models. The results suggest that, regardless of location, consumers place a strong premium on price and labeling claims. Three consumer segments are identified in each city; in Toronto, these segments are labeled Fair Trade-Focused, Price Conscious, and Balanced Buyers; for Vancouver these segments are labeled Organic and Fair Trade-Focused, Price Conscious, and Balanced Buyers. Although a broad spectrum of variables influences segment membership, no single variable explains membership in the same segment in each city. Such a result is rather telling; it suggests deeper constructs underlie segment membership, and presumably consumption behavior with respect to Fair Trade coffee. © 2010 Wiley Periodicals, Inc.

Alcohol-Related Problems, Drug Use, and Male Intimate Partner Violence Severity Among US Couples

ALCOHOLISM, Issue 4 2002
Carol B. Cunradi
Background: Particularly for women, level of intimate partner violence (IPV) severity is associated with risk of injury. Previous research suggests that male drinking problems and drug use are key risk factors. Few studies, however, have examined the associations between male and female alcohol problems and drug use and risk of moderate and severe male IPV in general household population samples. Methods: A multiethnic sample of 1615 married and cohabiting couples was obtained from the 1995 National Study of Couples, a cross-sectional study on alcohol and IPV. We assessed the contribution of past year male and female alcohol-related problems (i.e., drinking consequences and alcohol-dependence symptoms) and illicit drug use to the risk of moderate and severe male IPV. A series of generalized multinomial logit models, with adjustment for sociodemographic and psychosocial covariates, was constructed to assess these associations. Results: Female and male alcohol-related problems and female drug use, were associated with increased risk of moderate and severe male IPV. Contrary to our expectation, male drug use was not associated with elevated risk for either type of male IPV. Compared with couples residing in low-unemployment neighborhoods, couples residing in high-unemployment neighborhoods were at greater risk for severe, but not moderate, male IPV. Conclusions: Alcohol-related problems among men and women and drug use among women, appear to be important correlates of male IPV severity among couples in the general population. These findings can aid in IPV screening efforts, the formulation of prevention strategies, and help inform batterer and victim treatment programs. [source]


Mobility, Residential Location and the American Dream: The Intrametropolitan Geography of Minority Homeownership

REAL ESTATE ECONOMICS, Issue 3 2008
Stuart A. Gabriel
This article applies data from Washington, DC, Chicago and Los Angeles to estimate three-level nested multinomial logit models of household mobility, residential location and homeownership tenure choice. Model simulation indicates that shocks to income can significantly elevate the homeownership attainment of minority households; however, their urban settlement and homeownership patterns remain substantially more concentrated than those of whites. Simulated equilibration of black economic status with that of whites results in an approximate doubling of homeownership rates among black movers to central city areas. In contrast, homeownership rates among black movers to suburban and outlying areas lag far behind those of whites. [source]


Evaluating off-site environmental mitigation using choice modelling,

AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 4 2008
Geoffrey N. Kerr
Evaluation of off-site mitigation entails comparison of utility changes between two sites. Choice modelling has been used to identify community willingness to trade-off attributes for two different types of stream in New Zealand. Estimated utility functions are used to derive marginal rates of substitution and stream attribute part worths which can be used to design or evaluate both on-site and off-site mitigation policy. Latent class multinomial logit models identified classes of citizens who valued stream attributes quite differently. Significant differences in values for some attributes on different stream types imply heterogeneous mitigation ratios across environmental attributes. [source]
