Does investor ownership of nursing homes compromise the quality of care?

OBJECTIVES: Two thirds of nursing homes are investor owned. This study examined whether investor ownership affects quality. METHODS: We analyzed 1998 data from state inspections of 13,693 nursing facilities. We used a multivariate model and controlled for case mix, facility characteristics, and location. RESULTS: Investor-owned facilities averaged 5.89 deficiencies per home, 46.5% higher than nonprofit facilities and 43.0% higher than public facilities. In multivariate analysis, investor ownership predicted 0.679 additional deficiencies per home; chain ownership predicted an additional 0.633 deficiencies. Nurse staffing was lower at investor-owned nursing homes. CONCLUSIONS: Investor-owned nursing homes provide worse care and less nursing care than do not-for-profit or public homes.

State Medicaid programs offering personal care services.

Two Medicaid programs offer personal care services: (1) the Title XIX Personal Care Services (PCS) optional State plan benefit; and (2) the 1915(c) home and community-based services (HCBS) waivers. By 1998-1999, 26 States offered the PCS optional State plan benefit; 45 offered personal care services via a waiver(s). Nationwide, the former program was larger. The latter was the more popular administrative mechanism, possibly because it more reliably controls growth. States vary dramatically in terms of Medicaid personal care. Medicaid personal care participants per 1,000 State population ranged from 7.33 to 0.04. Per capita expenditures ranged from $91.21 to $0.02.

Nursing home staffing and its relationship to deficiencies.

OBJECTIVES: The authors examined the relationships between different types of nursing home staffing and nursing home deficiencies to test the hypothesis that fewer staff hours would be associated with higher numbers of deficiencies. METHODS: Data were from the On-Line Survey, Certification, and Reporting System for all certified nursing homes in the United States. Regression models examined total deficiencies, quality of care, quality of life, and other deficiencies. RESULTS: Fewer registered nurse hours and nursing assistant hours were associated with total deficiencies and quality of care deficiencies, when other variables were controlled. Fewer nursing assistant staff and other care staff hours were associated with quality of life deficiencies. Fewer administrative staff hours were associated with other deficiencies. Facilities that had more depressed and demented residents, that were smaller, and that were nonprofit or government-owned had fewer deficiencies. Facilities with more residents with urinary incontinence and pressure sores and with higher percentages of Medicaid residents had more deficiencies, when staffing and resident characteristics were controlled. DISCUSSION: Facility characteristics and states were stronger predictors of deficiencies than were staffing hours and resident characteristics. Because only a small portion of the total variance in deficiencies could be explained, much work remains to explore factors that influence deficiencies.

Experts recommend minimum nurse staffing standards for nursing facilities in the United States.

The experts concluded that current data show that the average nurse staffing levels (for RNs, LVN/LPNs, and NAs) in nursing homes are too low in some facilities to provide high quality of care. Caregiving, the central feature of a nursing home, needs to be improved to ensure high quality of care to residents. Because detailed time studies have not been conducted on the amount of time that is required to provide high quality of care to residents, expert opinion is currently the best approach to addressing the problem of inadequate staffing. Increases in the education level and training of nursing staff are also strongly recommended as a step to improving quality of care and reducing turnover rates in nursing homes. These recommendations are designed for consideration by Congress, HCFA regulators, policymakers, nursing home administrators, and nurses. Ideally, Congress would pass legislation establishing these recommendations as minimum standards for all nursing homes or direct HCFA to establish detailed minimum nurse staffing standards to ensure that staffing levels take into account the number and the case-mix of the residents. Alternatively, HCFA could introduce minimum staffing standards through the regulatory process. In 1999 there were a number of efforts at the state level to increase minimum staffing levels. Mohler (1999) surveyed selected states and found that 21 states had either proposed new legislation or were considering proposals for new legislation or new regulations. In California, for example, in 1999 the state budget approved $31 million in new state funds (to be matched with $31 million in federal Medicaid dollars) to increase nursing home staffing minimum requirements from 2.8 to 3.2 hr per resident day and to increase wage rates. Overall, nursing facilities need to be held accountable by HCFA for providing adequate levels and types of staffing to meet the needs of their residents, especially because government is paying for 61% of the expenditures. Adopting these minimum standards will have an important impact on improving the quality of the nation's nursing home care. Additional research is needed to determine appropriate levels and types of staff to provide high quality of care to residents. These studies could test the proposed staffing standards against existing staffing levels to examine the impacts on quality. As new data become available on staffing levels, revisions of staffing standards should be made if necessary to ensure that high standards are maintained.

Predicting state Medicaid home and community based waiver participants and expenditures, 1992-1997.

PURPOSE: The study examined trends and predictors of state Medicaid home and community based waiver participants and expenditures from 1992 to 1997 to identify factors of interest to policy makers and clinicians. DESIGN AND METHODS: HCFA Form 372 data were collected from state officials for each waiver for each year. Two separate regression analyses were conducted to examine the effects of sociodemographic, economic, political, policy, and health services on state waiver participants and expenditures. RESULTS: State waiver participants were positively associated with those aged 85 and over, personal income, residential care beds, and inpatient users and negatively with home health regulation and nursing home beds. State waiver expenditures were positively associated with democratic governors, personal income, home health reimbursement methods, Medicaid eligibility, home health agencies, and Medicare home health users. IMPLICATIONS: The factors policy makers might consider changing include increasing the number of residential care beds and home health agencies, removing certificate of need for home health care, using Medicare home health reimbursement methods for Medicaid, and raising the Medicaid eligibility criteria. In some states with low nursing home occupancy rates, reducing the supply of nursing home beds may also be considered. All of these approaches would be controversial and should be based on additional cost-effectiveness analysis.

Neuropathological findings in the very old. Results from the first 101 brains of a population-based longitudinal study of dementing disorders.

We report a unique longitudinal epidemiological study of cognitive decline in the elderly population of the city of Cambridge, UK. A population sample of people aged 75 and over was surveyed between 1984-1996 (n = 2,616) and followed 2.4, 6, and 9 years later. CAMDEX diagnostic criteria were used for clinical assessment, and the neuropathological protocol (in 101 cases) was based on the CERAD method, with additional features to allow Braak staging of neurofibrillary pathology. The main findings are of the heterogeneity of lesions to be found in very old populations, and the existence of considerable overlap in the pathologies found in the demented and nondemented. It seems that white matter (ischemic) pallor an amyloid angiopathy, as well as neuritic plaques, neurofibrillary tangles and Lewy body formation are all lesions that increase the likelihood of dementia.

Medicaid nursing facility reimbursement methods: 1979-1997.

This article describes state Medicaid nursing facility reimbursement methods and rates in 1979-1997, using data derived from telephone surveys of state Medicaid reimbursement. The 1980s saw shifts toward prospective methodology. The late 1980s and early 1990s were characterized by adoption of casemix methods. The early 1990s also saw fewer changes in methodology with a hiatus in the mid-1990s followed recently by renewed changes to methodology. Medicaid per diem rates have increased faster than inflation but less rapidly than general health costs. The repeal of the Boren Amendment may now allow states to institute greater cost controls or moratoria on rate increases. Despite states' tendencies to follow one another's examples, Medicaid reimbursement remains diverse nationally, with wide differences in policies and rates.

State Medicaid home health licensing and certification.

This study collected and analyzed data on the number of licensed and certified home health care agencies and licensed home care/personal care agencies in the US. The study also examined the state laws and regulations pertaining to Medicaid home health agency requirements. There were 14,045 licensed home health agencies and 801 other licensed home care or personal care agencies in the US, but only 59 percent of these agencies were certified in 1998. The percent of certified agencies ranged from 22 percent in Maryland to 100 percent in ten states that only allowed certified agencies to provide home care. There was a wide range in the number of agencies in states with the average being 6.1 agencies per 100,000 population. The 41 states with state licensing of home health agencies had a wide range of policies but most were more lenient than the federal Medicare certification requirements.

A cost analysis of diabetic lower-extremity ulcers.

OBJECTIVE: Our objectives were to 1) estimate the prevalence of diabetes and diabetic lower-extremity ulcers in the Medicare population, 2) characterize Medicare population-specific costs for lower-extremity ulcer episodes, and 3) evaluate potential cost savings associated with better healing of lower-extremity ulcers. RESEARCH DESIGN AND METHODS: Prevalence and costs of diabetic lower-extremity ulcers were obtained by an analysis of Medicare claims data from 1995 and 1996 Standard Analytic Files (5% sample). RESULTS: Medicare expenditures for lower-extremity ulcer patients were on average 3 times higher than those for Medicare patients in general ($15,309 vs. $5,226). Lower-extremity ulcer-related spending accounted for 24% of total spending for lower-extremity ulcer patients. Most of the ulcer-related costs accrued on the inpatient side (73.7%); proportionately smaller amounts went to physicians and nursing home facilities. To determine the potential effect of better diabetic ulcer management, a model was created that estimated the impact on costs with improved healing rates. Improving the 20-week healing rate from 31 to 40% would save Medicare $189 per episode. CONCLUSIONS: Lower-extremity ulcers cost the Medicare system $1.5 billion in 1995. Any wound care intervention that could prevent even a small percentage of wounds from progressing to the stage at which inpatient care is required may have a favorable cost effect on the Medicare system.

Implementing the second generation social health maintenance organization.

BACKGROUND: In 1996 the Health Care Financing Administration implemented a second generation of the Social HMO demonstration. This model retained the chronic care benefits of the original Social HMOs while attempting to develop a geriatric service model integrated into primary care and a screening and assessment process focused directly on healthcare risk factors. Other refinements included risk-adjusted capitation payment, broadened eligibility for expanded care benefits, low co-payments for these benefits, and no caps on the expanded care benefits expenditures. OBJECTIVES: The geriatric approach is designed to facilitate integration among providers and levels of care. This includes timely application of primary care monitoring and treatment to reduce illness and disability as well as a geriatric education and consultation program to provide specialty support for complex cases. Care management is designed for those requiring home-based care, those discharged from hospitals or nursing homes, and those having difficulty with treatment regimens. DESIGN: A case study of the Social HMO implementation through the Fall of 1999. SETTING: Health Plan of Nevada (HPN), with locations in Las Vegas, Reno, and surrounding areas. PARTICIPANTS: More than 25,000 Medicare beneficiaries participated during the study period. MEASUREMENTS: Administrative reports, charts, and interviews with administrators and clinicians. RESULTS: Within 12 months of operation under this authority, HPN succeeded in putting in place most of the components of the planned geriatric approach: a screening program to identify patients "at risk" for high service costs and disability and timely application of primary care treatment to reduce illness and disability. Geriatric education and a consultation program for complex cases were available, but full implementation was delayed until the plan was able to hire a full time geriatrician. CONCLUSIONS: Health Plan of Nevada's Social HMO program reflects current perspectives on how to integrate chronic care into an HMO. The accomplishments affirm that the provision of risk-adjusted reimbursement, along with the 5 % supplement to the normal Medicare capitation payment, are sufficient incentives for a health plan to restructure itself so that it places a priority on retaining and serving populations at risk for high expenditures.

Medicaid 1915(c) home and community-based services waivers across the states.

This article provides State-level data on the Medicaid 1915(c) home and community-based services (HCBS) waivers program. Medicaid 1915(c) waiver participants were 32 percent of the Medicaid participants in institutional care in 1997. These data document wide interstate variation in organizational oversight and program policies for the waivers. Many structural barriers to HCBS waiver growth existed. Case management services, in some form, were normative for most HCBS waiver participants, but formal mechanisms to assess client satisfaction and service quality were less common. Substantial new growth in this program may require fundamental changes in HCBS waiver policies.

Saccharomyces cerevisiae Ntg1p and Ntg2p: broad specificity N-glycosylases for the repair of oxidative DNA damage in the nucleus and mitochondria.

Saccharomyces cerevisiae possesses two functional homologues (Ntg1p and Ntg2p) of the Escherichia coli endonuclease III protein, a DNA base excision repair N-glycosylase with a broad substrate specificity directed primarily against oxidatively damaged pyrimidines. The substrate specificities of Ntg1p and Ntg2p are similar but not identical, and differences in their amino acid sequences as well as inducibility by DNA damaging agents suggest that the two proteins may have different biological roles and subcellular locations. Experiments performed on oligonucleotides containing a variety of oxidative base damages indicated that dihydrothymine, urea, and uracil glycol are substrates for Ntg1p and Ntg2p, although dihydrothymine was a poor substrate for Ntg2p. Vectors encoding Ntg1p-green fluorescent protein (GFP) and Ntg2p-GFP fusions under the control of their respective endogenous promoters were utilized to observe the subcellular targeting of Ntg1p and Ntg2p in S. cerevisiae. Fluorescence microscopy of pNTG1-GFP and pNTG2-GFP transformants revealed that Ntg1p localizes primarily to the mitochondria with some nuclear localization, whereas Ntg2p localizes exclusively to the nucleus. In addition, the subcellular location of Ntg1p and Ntg2p confers differential sensitivities to the alkylating agent MMS. These results expand the known substrate specificities of Ntg1p and Ntg2p, indicating that their base damage recognition ranges show distinct differences and that these proteins mediate different roles in the repair of DNA base damage in the nucleus and mitochondria of yeast.

Association between Alzheimer's disease and the NOS3 gene.

Alzheimer's disease (AD) is the most common form of neurodegenerative disorder of later life. Genetic studies have demonstrated that the apolipoprotein E (ApoE) gene is an important susceptibility locus; however, other environmental and genetic factors operating alone or in combination with ApoE must also be involved. Among candidate genes that may contribute to this residual risk is the endothelial nitric oxide synthase (NOS3) gene. NO release from vascular endothelium accounts in large part for endothelium-derived relaxing factor bioactivity. Abnormalities of cerebral small vessels occur early in AD, and it has been demonstrated recently that beta-amyloid interacts with endothelial cells in blood vessels to produce an excess of superoxide radicals. We have genotyped 122 cases of early-onset AD (EOAD) and 317 cases of late-onset AD (LOAD) as well as 392 controls for a common structural polymorphism Glu/Asp at codon 298 in the NOS3 gene. We find a highly significant enrichment for Glu/Glu homozygotes in LOAD compared with controls. The effect appears to be independent of ApoE status. NOS3 may be a new genetic risk factor for LOAD.
