Cross-state variation in conceptions of quality of nursing facility long-term care for the elderly

We address two issues in this exploratory study. First, to what degree do variables prominent in explaining cross-state variation in the generosity of other public assistance programs also help to explain the resources states devote to nursing facility long-term care for the elderly, a service supported largely by states' Medicaid programs? Second, to what degree do the resources that states commit to this purpose influence the quality of state nursing facility processes and, in turn, translate into state nursing facility residents' quality-of-life outcomes? We find unusual features to the pattern of factors explaining state resource levels. We also find surprises in relations among the three aspects of quality, but overall, raising resource adequacy improves nursing facility process quality, which, in turn, bolsters nursing facility residents' quality-of-life outcomes. We close with suggestions for further improvement.     

Do high rates of OSCAR deficiencies prompt improved nursing facility processes and outcomes?

Recently, some researchers have argued that high state rates of Centers for Medicare and Medicaid Services (CMS) Online Survey, Certification and Reporting (OSCAR) nursing facility deficiencies indicate stringent enforcement, leaving the impression of better-quality care soon to follow; others maintain that the rank ordering of states' quality of nursing facility care remains fairly constant, resting on deep-seated state characteristics that change slowly, so that short-term improvement in poor-quality care is unlikely. The authors examine change in the process and outcome quality of states' Medicare nursing facility long-term care programs across 1999 to 2005, using linear and two-stage least squares regression. They find that (1) nationally, process quality generally falls across this period while outcome quality generally increases; (2) neither a prominent enforcement stringency index nor state culture, a relatively stable state characteristic, exerts much influence on state process and outcome quality scores over time, but (3) the relative costs and benefits for CMS compliance appear to contribute to explaining change in states' quality of resident outcomes over time; and (4) states' process quality is much less stable than outcome quality, and outcome indices distinct from OSCAR deficiency data provide more reliable and possibly more valid measures of care quality.

Monitoring Quality of Care in Residential Care for the Elderly: The Information Challenge

This study assesses the administrative data compiled on residential care facilities for the elderly (RCFEs) by the state of California and considers the feasibility of their adaptation into a comprehensive information system. Required state RCFE reporting forms were reviewed for potential data elements. Recording and reporting variation was evaluated using a stratified probability sample of 340 facilities licensed in Northern and Central California. Stratification was by facility size and state district office. Data collection included a 5-year retrospective review of forms and documents in each facility's public file. Little of the information required from RCFEs is computerized. Most of it is maintained at the individual facility and not included in public files. Basic information, while included in the public file, is commonly either not available or not current. Resident characteristics and outcomes are not compiled, except indirectly in citations. The information required from RCFEs, if appropriately compiled and maintained, would produce a comprehensive quality assurance system and more effectively support consumer information and policy needs.     

Relationship of Facility Characteristics and Presence of an Ombudsman to Missouri Long-Term Care Facility State Inspection Report Results

This study analyzes existing data describing general facility characteristics, the presence of an ombudsman in the facility, and the number of deficiencies/violations reported for long-term care facilities in the state of Missouri. The model that predicted the rate of deficiencies/violations best was one that included the following characteristics: “contained more than 50 beds” and “considered a Skilled Nursing facility.” Findings suggest that the characteristics that are significantly associated with fewer deficiencies are larger size (more than 50 beds) and being classified as Skilled Nursing. While those facilities that housed an ombudsman were found to have fewer deficiencies per bed in the general analysis, further investigation found this to be an artifact mostly due to the higher rate of ombudsmen at larger facilities.     

Chain reaction: an exploratory study of nursing home bankruptcy in California

This paper reports on an exploratory study of nursing home bankruptcy. From state and industry data regarding nearly 1,000 California facilities, it was possible to identify 155 homes in five chains (multi-facility organizations) that were operating in bankruptcy in 2000. When compared with facilities in non-bankrupt chains, while the bankrupt chain facilities had significantly worse financial liquidity, higher administrative costs, and higher payables to related parties, they also had more Medicare residents, fewer Medicaid residents, better solvency, and were located in less competitive county markets and in areas with higher Medicaid reimbursement rates. These findings indicate that, rather than facility characteristics and local market factors, strategic decisions taken at the corporate (chain) level are the major determinants of nursing facility bankruptcy status.     

Medicaid nursing facility reimbursement in flux: effects of federal regulatory changes and prevailing fiscal conditions, 1978-1998

Basic concepts and trends are examined in Medicaid nursing facility reimbursements between 1978 and 1998, because Medicaid payment reform is a common budget reduction strategy pursued by state officials. Non-incremental changes in state rate-setting methods, as well as incremental changes in per diem rates and expenditures per recipient, are analyzed. In addition to substantial cross-state variation, results reveal clear trends in reimbursement policy characteristics over time. Not only do these track closely with changes in the federal regulatory environment, but they also track closely with prevailing fiscal and economic conditions. Given the serious ramifications reimbursement policy changes can have for nursing home residents and providers, it is imperative that the impact of federal disengagement from this policy area be understood.     

Staffing-Related Deficiency Citations in Nursing Homes

There is evidence that staffing characteristics influence quality of care in nursing homes. Federal and state surveyors conduct inspections of homes to assess their compliance with regulatory standards, including requirements related to staffing. Deficiency citations are issued when these standards are not met. This article examines the relationship between operational, facility, and market characteristics and organizational performance measured as staffing-related deficiency citations. Online Survey Certification of Automated Records (OSCAR) data from 2000 through 2007 were used with multinomial logistic regression analyses to identify factors associated with deficiency citations for staffing. Chain members and facilities with poor quality of care were more likely to receive deficiency citations for staffing. Greater bed count and competition between nursing homes were associated with a decreased likelihood of deficiency citations for staffing. Staffing-related deficiencies within nursing homes vary according to various operational, facility, and market characteristics.     

Consumer Protection for Prospective Assisted Living Facility Residents: Gordian Knot or Solvable Problem?

The consumer protection safety net for prospective assisted living facility residents and their caregivers is a work in progress and is filled with numerous potential pitfalls. Notwithstanding a recent deluge of recent state legislation, baselines in crucial areas remain erratic and confusing; in addition, useful factual information is hard to come by. Using a legal perspective, based on statutory and regulatory examples from different states and interviews with industry stakeholders, the author explores the causes of assisted living facilities choice problems, potential solutions, and the obstacles affecting these solutions.
