PURPOSE Mortality data are important tools for research requiring vital status information. We reviewed the major mortality databases and mortality ascertainment services available in the United States, including the National Death Index (NDI), the Social Security Administration (SSA) files, and the Department of Veterans Affairs databases. METHODS The(More)
This study tested the cross-sectional relationship between caregiver burden and health-related quality of life (HRQOL) among 1,594 caregivers of veterans identified to qualify for formal home care. A two-stage model found that familial relationship, coresidence, and low income predicted objective burden. Coresidence also predicted subjective burden, whereas(More)
CONTEXT Although home-based health care has grown over the past decade, its effectiveness remains controversial. A prior trial of Veterans Affairs (VA) Team-Managed Home-Based Primary Care (TM/HBPC) found favorable outcomes, but the replicability of the model and generalizability of the findings are unknown. OBJECTIVES To assess the impact of TM/HBPC on(More)
OBJECTIVE To examine the impact of home care on hospital days. DATA SOURCES Search of automated databases covering 1964-1994 using the key words "home care," "hospice," and "healthcare for the elderly." Home care literature review references also were inspected for additional citations. STUDY SELECTION Of 412 articles that examined impact on hospital(More)
The U.S. Department of Veterans Affairs (VA) operates and maintains one of the largest health care systems under a single management structure in the world. The coordination of administrative and clinical information on veterans served by the VA health care system is a daunting and critical function of the Department. This article provides an overview of VA(More)
The amount of VA data available for analysis can be overwhelming to individuals who need to translate these data into usable information. The Atlas, using current GIS technology, was funded to provide data in a comprehensive guide. Patients were identified using a disease classification scheme based on Kaiser Permanente methodology and the Clinical(More)
This paper is an overview of hospital closure in the United States for the five-year period 1976-1980. We describe the distributional patterns of closings among noncommunity and community hospitals classified according to institutional characteristics such as bed size, control, and location.

DESIGN Descriptive and regression analyses of responses from a mail survey. PARTICIPANTS Forty-five physicians affiliated with VA HBPC(More)
The atomic simulation environment (ASE) is a software package written in the Python programming language with the aim of setting up, steering, and analyzing atomistic simulations. In ASE, tasks are fully scripted in Python. The powerful syntax of Python combined with the NumPy array library make it possible to perform very complex simulation tasks. For(More)
