Early experience with a new model of employer group purchasing in Minnesota.
(49/1342)
The Buyers Health Care Action Group (BHCAG) in the Twin Cities has implemented a new purchasing initiative that offers employees a choice among care systems with nonoverlapping networks of primary care providers. These systems offer a standardized benefit package, submit annual bids, and are paid on a risk-adjusted basis. Employees are provided with information on quality and other differences among systems, and most have financial incentives to choose lower-cost systems. Generally, providers have responded favorably to direct contracting and to risk-adjusted payments but have concerns about the risk-adjustment mechanism used and, more importantly, the strength of employers' commitment to the purchasing model.

Airborne concentrations of PM(2.5) and diesel exhaust particles on Harlem sidewalks: a community-based pilot study.
(50/1342)
Residents of the dense urban core neighborhoods of New York City (NYC) have expressed increasing concern about the potential human health impacts of diesel vehicle emissions. We measured concentrations of particulate matter [less than/equal to] 2.5 micro in aerodynamic diameter (PM(2.5)) and diesel exhaust particles (DEP) on sidewalks in Harlem, NYC, and tested whether spatial variations in concentrations were related to local diesel traffic density. Eight-hour (1000-1800 hr) air samples for PM(2.5 )and elemental carbon (EC) were collected for 5 days in July 1996 on sidewalks adjacent to four geographically distinct Harlem intersections. Samples were taken using portable monitors worn by study staff. Simultaneous traffic counts for diesel trucks, buses, cars, and pedestrians were carried out at each intersection on [Greater/equal to] 2 of the 5 sampling days. Eight-hour diesel vehicle counts ranged from 61 to 2,467 across the four sites. Mean concentrations of PM(2.5) exhibited only modest site-to-site variation (37-47 microg/m(3)), reflecting the importance of broader regional sources of PM(2.5). In contrast, EC concentrations varied 4-fold across sites (from 1.5 to 6 microg/m(3)), and were associated with bus and truck counts on adjacent streets and, at one site, with the presence of a bus depot. A high correlation (r = 0.95) was observed between EC concentrations measured analytically and a blackness measurement based on PM(2.5) filter reflectance, suggesting the utility of the latter as a surrogate measure of DEP in future community-based studies. These results show that local diesel sources in Harlem create spatial variations in sidewalk concentrations of DEP. The study also demonstrates the feasibility of a new paradigm for community-based research involving full and active partnership between academic scientists and community-based organizations. (+info)
A review of trauma systems using the Calgary model.
(51/1342)
Surgeons caring for severely injured patients have witnessed tremendous change over the past 2 decades with the rapid evolution of trauma systems. This paper describes the evolution of trauma systems in Canada, using the one in Calgary as a model. Canadian system guidelines were produced by the Trauma Association of Canada in 1993. Participation in Canadian accreditation is accelerating as increasingly more centres across the country undergo external review each year. Reporting of trauma outcomes, including standardized mortality and a variety of performance measures, is becoming the norm. Injury is being treated as a disease with comprehensive control strategies aimed at reducing death and disability rates through prevention, treatment and rehabilitation. (+info)
Designing a Medicare prescription drug benefit: issues, obstacles, and opportunities.
(52/1342)
We review the policy concerns underlying some of the most contentious issues that must be resolved prior to the enactment of a Medicare drug benefit. We consider critical issues both in benefit design-targeted versus universal eligibility, benefit subsidies, and benefit comprehensiveness--and in benefit administration, focusing especially on issues involving the administration of the drug benefit in traditional Medicare. Despite the apparent contentiousness of the drug benefit debate, alternative proposals may not be so far apart on these issues. (+info)
Comparing consumer-directed and agency models for providing supportive services at home.
(53/1342)
OBJECTIVE: To examine the service experiences and outcomes of low-income Medicaid beneficiaries with disabilities under two different models for organizing home-based personal assistance services: agency-directed and consumer-directed. DATA SOURCE: A survey of a random sample of 1,095 clients, age 18 and over, who receive services in California's In-Home Supportive Services (IHSS) program funded primarily by Medicaid. Other data were obtained from the California Management and Payrolling System (CMIPS). STUDY DESIGN: The sample was stratified by service model (agency-directed or consumer-directed), client age (over or under age 65), and severity. Data were collected on client demographics, condition/functional status, and supportive service experience. Outcome measures were developed in three areas: safety, unmet need, and service satisfaction. Factor analysis was used to reduce multiple outcome measures to nine dimensions. Multiple regression analysis was used to assess the effect of service model on each outcome dimension, taking into account the client-provider relationship, client demographics, and case mix. DATA COLLECTION: Recipients of IHSS services as of mid-1996 were interviewed by telephone. The survey was conducted in late 1996 and early 1997. PRINCIPAL FINDINGS: On various outcomes, recipients in the consumer-directed model report more positive outcomes than those in the agency model, or they report no difference. Statistically significant differences emerge on recipient safety, unmet needs, and service satisfaction. A family member present as a paid provider is also associated with more positive reported outcomes within the consumer-directed model, but model differences persist even when this is taken into account. Although both models have strengths and weaknesses, from a recipient perspective the consumer-directed model is associated with more positive outcomes. CONCLUSIONS: Although health professionals have expressed concerns about the capacity of consumer direction to assure quality, particularly with respect to safety, meeting unmet needs, and technical quality, our findings suggest that the consumer-directed service model is a viable alternative to the agency model. Because public programs are under growing pressure to address the long-term care needs of low-income people of all ages with disabilities, the Medicaid personal assistance benefit needs to be reassessed in light of these findings. Consumer-directed models may offer a less elaborate and possibly less costly option for organizing supportive services at home. Study limitations may limit the generalizability of these findings. This was a natural experiment, in which only some counties offered both service models and counties assigned recipients to a service model. The use of a telephone survey excluded important recipient subsets, notably people with severe cognitive impairments. A more definitive study would include direct observations as well as survey approaches. (+info)
Impact of HMO market structure on physician-hospital strategic alliances.
(54/1342)
OBJECTIVE: To assess the impact of HMO market structure on the formation of physician-hospital strategic alliances from 1993 through 1995. The two trends, managed care and physician-hospital integration have been prominent in reshaping insurance and provider markets over the past decade. STUDY DESIGN: Pooled cross-sectional data from the InterStudy HMO Census and the Annual Survey conducted by the American Hospital Association (AHA) between 1993 and the end of 1995 to examine the effects of HMO penetration and HMO numbers in a market on the formation of hospital-sponsored alliances with physicians. Because prior research has found nonlinear effects of HMOs on a variety of dependent variables, we operationalized HMO market structure two ways: using a Taylor series expansion and cross-classifying quartile distributions of HMO penetration and numbers into 16 dummy indicators. Alliance formation was operationalized using the presence of any alliance model (IPA, PHO, MSO, and foundation) and the sum of the four models present in the hospital. Because managed care and physician-hospital integration are endogenous (e.g., some hospitals also sponsor HMOs), we used an instrumental variables approach to model the determinants of HMO penetration and HMO numbers. These instruments were then used with other predictors of alliance formation: physician supply characteristics, the extent of hospital competition, hospital-level descriptors, population size and demographic characteristics, and indicators for each year. All equations were estimated at the MSA level using mixed linear models and first-difference models. PRINCIPAL FINDINGS: Contrary to conventional wisdom, alliance formation is shaped by the number of HMOs in the market rather than by HMO penetration. This confirms a growing perception that hospital-sponsored alliances with physicians are contracting vehicles for managed care: the greater the number of HMOs to contract with, the greater the development of alliances. The models also show that alliance formation is low in markets where a small number of HMOs have deeply penetrated the market. First-difference models further show that alliance formation is linked to HMO consolidation (drop in the number of HMOs in a market) and hospital downsizing. Alliance formation is not linked to changes in hospital costs, profitability, or market competition with other hospitals. CONCLUSIONS: Hospitals appear to form alliances with physicians for several reasons. Alliances serve to contract with the growing number of HMOs, to pose a countervailing bargaining force of providers in the face of HMO consolidation, and to accompany hospital downsizing and restructuring efforts. IMPLICATIONS FOR POLICY, DELIVERY, OR PRACTICE: Physician-hospital integration is often mentioned as a provider response to increasing cost-containment pressures due to rising managed care penetration. Our findings do not support this view. Alliances appear to serve the hospital's interest in bargaining with managed care plans on a more even basis. (+info)
Public health advocacy: process and product.
(55/1342)
OBJECTIVES: In this article the author describes public health advocacy and proposes a conceptual framework for understanding how it works. METHODS: The proposed framework incorporates the image of an assembly line. The public health advocacy assembly line produces changes in societal resource allocation that are necessary for optimizing public health. The framework involves 3 main stages: information, strategy, and action. These stages are conceptually sequential but, in practice, simultaneous. The work at each stage is continually adjusted according to circumstances at the other stages. RESULTS: The framework has practical implications; for example, public health advocacy teams need members with complementary skills in distinct roles. Potential applications are illustrated via two public health advocacy efforts. CONCLUSIONS: The framework may be useful in assessing staffing and funding needs for public health advocacy endeavors, explaining common problems in these endeavors and suggesting solutions, and guiding decisions concerning effort allocation. Application of the framework to a variety of public health advocacy endeavors will clarify its strengths and weaknesses. (+info)
Conceptualizing and applying a minimum basic needs approach in southern Philippines.
(56/1342)
This study, a collaboration between Canadian and Filipino researchers, focuses on how the national government's Minimum Basic Needs (MBN) Approach has been implemented at the local level in some selected sites in Region XI on the Philippine island of Mindanao. This case study of MBN implementation focuses on the experiences of three municipalities and three barangays (villages) within them. The research explores, through interviews and group discussions, what the mayors, technical working groups and volunteer health workers in these areas thought about MBN and how they participated in the initiative. The objectives of the study were: to explore models of MBN data utilization at the municipal and barangay levels; to understand how the MBN data guided decision-making about community priorities and resource allocation; to examine the role that community volunteers played in promoting the use of MBN data, and in community health and development activities which ensued; and to determine what factors challenged or encouraged the use of MBN data for social development at the barangay level. In all the sites, MBN had some impact, most often due to methods of concentrating information on unmet basic needs locally and making use of it in planning and project development processes. The findings show that although there is still some way to go before MBN is effectively integrated into local planning and project development, some responses to problems have been implemented and innovative projects were undertaken or being considered.
