The Effect Of Health Information Technology On Quality In U.S. Hospitals

Health information technology (IT), such as computerized physician order entry and electronic health records, has potential to improve the quality of health care. But the returns from widespread adoption of such technologies remain uncertain. We measured changes in the quality of care following adoption of electronic health records among a national sample of U.S. hospitals from 2004 to 2007. The use of computerized physician order entry and electronic health records resulted in significant improvements in two quality measures, with larger effects in academic than nonacademic hospitals. We conclude that achieving substantive benefits from national implementation of health IT may be a lengthy process. Policies to improve health ITs efficacy in nonacademic hospitals might be more beneficial than adoption subsidies.

Do rural elders have limited access to Medicare hospice services

Objectives:  To examine whether there are urban‐rural differences in use of the Medicare hospice benefit before death and whether those differences suggest that there is a problem with access to hospice care for rural Medicare beneficiaries.

Interspecialty variation in office-based care

Analysis of national survey data on physician-patient encounters raises questions about physician education and manpower policy. Data compiled by the University of Southern California Medical Activities and Manpower Projects and the United States Bureau of Health Professionals reveal differences among internists, cardiologists, family practitioners, and pediatricians in procedures used for diagnosing and treating several frequently encountered conditions. Differences are observed in expenditure of time and use of a broad range of diagnostic and therapeutic techniques. These differences remain significant even after several important characteristics of individual physicians, patients, and the practice environment have been controlled. Findings from this study underscore the necessity of reviewing the content of medical education and policies that encourage a broad range of specialists to provide primary care. The findings also emphasize the need to address the physicians knowledge base in promoting changes in practice patterns.

Substitution of formal and informal care for the community-based elderly.

The Minnesota Pre-Admission Screening/Alternative Care Grants Program screens those at risk of nursing home placement and funds services that will allow the elderly to be cared for at home. Information was collected for a 1-year period on client placement, health and functional status, informal support, use of health and formal services, and care-giver characteristics for 214 clients screened during the last quarter of 1984. A two-equation model was hypothesized to examine the formal service decisions of case managers and the amount of informal care provided for elderly clients at risk of institutionalization. A system of two simultaneous equations was estimated using a two-stage leastsquares approach. The findings suggest that case managers allocate formal services based primarily on client need. The amount of informal care provided to clients did not affect significantly the decisions of case managers and is not determined significantly by the amount of formal services received by the elderly in the community. The lack of substitution between formal services and informal care reinforces the findings of previous research

Use of community-based mental health programs by HMOs: evidence from a Medicaid demonstration.

BACKGROUND Proposals to enroll Medicaid beneficiaries in health maintenance organizations (HMOs) have raised concerns that community-based mental health treatment programs would be adversely affected. METHODS In Hennepin County (Minnesota) 35% of Medicaid beneficiaries were randomly assigned to prepaid plans. Random samples of individuals with severe mental illness with selected from the prepaid enrollees and from beneficiaries remaining with traditional Medicaid. The two groups were compared with respect to their use of community treatment programs and the write-off (the proportion of patient charges for which payment was not received) experienced by those programs for members of the study sample. RESULTS There was no strong evidence that Medicaid beneficiaries with severe mental illness who were randomly assigned to prepaid plans used community-based mental health treatment programs differently than did other Medicaid beneficiaries. However, write-offs were consistently higher for enrollees in prepaid plans. CONCLUSIONS In the short run, the use of community-based mental health treatment programs need not be affected by enrollment of Medicaid beneficiaries in prepaid plans, providing that Medicaid program administrators take steps to minimize the disruption of ongoing treatment, offer beneficiaries a choice among prepaid plans, and encourage community treatment programs to contract with plans to serve beneficiaries.

Public health systems: a social networks perspective.

OBJECTIVE To examine the relationship between public health system network density and organizational centrality in public health systems and public health governance, community size, and health status in three public health domains. DATA SOURCES/STUDY SETTING During the fall and the winter of 2007-2008, primary data were collected on the organization and composition of eight rural public health systems. STUDY DESIGN Multivariate analysis and network graphical tools are used in a case comparative design to examine public health system network density and organizational centrality in the domains of adolescent health, senior health, and preparedness. Differences associated with public health governance (centralized, decentralized), urbanization (micropolitan, noncore), health status, public health domain, and collaboration area are described. DATA COLLECTION/EXTRACTION METHODS Site visit interviews with key informants from local organizations and a web-based survey administered to local stakeholders. PRINCIPAL FINDINGS Governance, urbanization, public health domain, and health status are associated with public health system network structures. The centrality of local health departments (LHDs) varies across public health domains and urbanization. Collaboration is greater in assessment, assurance, and advocacy than in seeking funding. CONCLUSIONS If public health system organization is causally related to improved health status, studying individual system components such as LHDs will prove insufficient for studying the impact of public health systems.

The Determinants of Time off Work after Childbirth

Relatively little is known about the role that leave policies--family, parental, or maternity-leave policies--play in facilitating time off work after childbirth. Yet time off is a critical element of leave policies, as it facilitates the mothers recovery from childbirth and promotes maternal-infant attachment. Using data from Minnesota, the state with the highest rate of female labor force participation, we examine the extent to which policies, relative to personal, job, and workplace characteristics, determine the duration of womens childbirth-related leaves from work. A random sample of women identified from vital statistics records is used to estimate the relationship between leave policies and time off work after childbirth. Of our sample 85 percent had access to some paid leave benefits, although only 46 percent had paid maternity leave benefits. The difference in duration of leave between women with and without paid leave policies was approximately four weeks, a substantial difference for most women and their infants. Paid leave policies and spousal earnings as primary determinants of maternal time off work, suggest problems in the use of unpaid leave for economically vulnerable women.

The Physician as Gatekeeper: Determinants of Physicians?? Hospitalization Rates

The authors studied differences in the rate of hospitalization of a random sample of all general and family practitioners in the state of Washington. The study was designed to identify nonmedical factors that affect the rate at which physicians hospitalize ambulatory patients. They found that the hospitalization rate varied greatly among physicians and that this rate appeared to be sensitive to nonmedical factors. The following independent variables were significantly associated with higher rates of hospitalization while controlling for other factors: low hospital occupancy rates, low per capita income in the county, group practice, a broader scope of outpatient practice, and a busier outpatient practice. They conclude that physicians are sensitive to a range of nonmedical factors in their decision to utilize hospital resources. These findings suggest that a substantial proportion of all hospitalizations are discretionary, and that changes in practice organization or hospital occupancy rates will affect the rate of hospital use.

A method for analyzing resource use in ambulatory care settings

The major objective of this research is to develop a methodological framework to help analyze the use of resources in ambulatory care environments. Emphasis is placed on trying to understand reasons for variation in treatment patterns.Important methodological considerations include: 1) the selection of a set of medical problems appropriate for evaluating the interaction effects of the variables being considered; 2) the development of problem-specific computerized routines for defining episodes of care based on patient visit information; and 3) the selection of appropriate measures of utilization.The Frontier Nursing Service (FNS) was used as a study setting. FNS is a primary health care service and training center located in Leslie County in eastern Kentucky, an area that covers 1,000 square miles with a population of approximately 15,000.The analysis indicates that for common primary care problems, the level of provider training as well as accessibility of services signficantly influence patterns of care.

Understanding Integrated Rural Health Networks

In an era of constraints on public and private sector health care budgets, organizational restructuring of hospital and physician practice, and the shifting of financial risk to patients and providers, rural health professionals and communities are grappling with the issue of how to assure access to a comprehensive and affordable set of health care services. In recent years, rural health providers have turned to the strategy of developing voluntary network relations as an alternative to system or diversification strategies that entail ownership and management by one entity. A systematic analysis of the cooperative efforts of selected providers results in a proposed definition of integrated rural health networks and highlights critical aspects of their formation and development.
