Improving primary care in nursing homes.

We conducted a quasi-experiment to evaluate the impact of a Medicare waiver which allowed the use of nurse practitioners (NPs) and physicians assistants (PAs) to deliver primary care to Massachusetts nursing home patients and removed the limits on the reimbursable numbers of visits per month. A carefully matched set of 1,327 Medicaid patients from 95 non-participating homes in the same areas of Massachusetts was compared to 1,324 Medicaid demonstration patients from 75 homes. Information came from specially designed record reviews and the Medicaid and Medicare information systems. Separate analyses were done for newly admitted cases and rollovers. Comparisons of quality of care suggested that the medical groups using NPs and PAs provided as good or better care than did the physicians in the control group. There were no differences in functional status changes or in the use of medications. The demonstration patients received more attention, as reflected in more orders written and an average of one additional visit a month. Demonstration patients showed higher scores on three of seven specially designed quality tracers, congestive heart failure and hypertension for both new administrations and rollovers, and new urinary incontinence for new admissions. Rollovers had significantly fewer emergency and total hospital days. A cost analysis suggests that the use of NPs and PAs saves at least as much as it costs and may save additional money with more sustained use.

Impact of geriatric nurse practitioners on nursing-home residents' functional status, satisfaction, and discharge outcomes.

This study evaluated the impact of geriatric nurse practitioners (GNP) employed by nursing homes on quality of patient care and residents' outcomes during a 12-month study period. Quality of care was assessed in standardized interviews of 525 residents in five nursing homes with GNPs and 323 residents in five other nursing homes without GNPs. Each resident was interviewed up to four times during the study period (at baseline, and 3, 6, and 12 months later) to determine functional status, satisfaction with care, and physical condition at each of these points. The only significant difference between groups was that fewer newly admitted residents were hospitalized from GNP homes than from those without a GNP. The results of this interview study showed that the GNP as a nursing home employee had little impact on residents' functional status, physical condition, or satisfaction.

Assessing cost effects of nursing-home-based geriatric nurse practitioners.

Employment of geriatric nurse practitioners (GNPs) is one strategy to improve nursing home care. The effects of GNPs on costs and profitability of nursing homes and on costs of patient medical service use outside the nursing home are examined. Employment of GNPs does not adversely affect nursing home costs or significantly affect profits. There is some evidence of cost savings in medical service use for newly admitted patients but no evidence of savings for continuing residents. GNPs reduce the use of hospital services for both groups, and the reduction is statistically significant for newly admitted patients.

Setting capitations for Medicaid: a case study.

This article examines the methodology New York State used to set capitation rates for a Medicaid health maintenance organization. By examining the methods used and the assumptions made in a particular case, some general lessons are drawn about the ratesetting process. Greater reliance on statewide data to assure fair and statistically stable estimates is needed. Although the article focuses on one State and its ratesetting for one particular plan (Health Care Plus), the issues raised have general interest for other plans and for other States concerned with the setting of capitation rates for Medicaid enrollees in prepaid plans.

Effects of room reflectance and background noise on perceived auditory distance.

Perceptions of egocentric auditory distance were investigated within an environment for which the reverberation time could be systematically varied without changes in the size or shape of the room. Two levels of wide-band background noise, differing by 20 dB, were used as a masking stimulus. Target sounds were presented from distances between 0.75 and 6.0 m and verbal reports of distance were collected from 288 listeners in two separate experiments. Changes in physical distance produced variation in reported distance in each configuration. Reported distance was generally proportional to real distance, but considerably underestimated when room reflectance was low. When room reflectance was high (T60 approximately 1.7 s for the range of frequencies used), initial reports of distance were often overestimates; upon repeated presentation, judgments in the high reflectance room became more nearly veridical. The effect of increasing the background noise level was to decrease the perceived distance. These findings are in accord with expectations based upon the importance of reverberation cue(s) to distance and upon previous analyses from this laboratory.

Effects of a geriatric nurse practitioner on process and outcome of nursing home care.

We compared measures of quality of care and health services utilization in 30 nursing homes employing geriatric nurse practitioners with those in 30 matched control homes. Information for this analysis came from reviews of samples of patient records drawn at comparable periods before and after the geriatric NPs were employed. The measures of geriatric nurse practitioner impact were based on comparisons of changes from pre-NP to post-NP periods. Separate analyses were done for newly admitted and long-stay residents; a subgroup of homes judged to be best case examples was analyzed separately as well as the whole sample. Favorable changes were seen in two out of eight activity of daily living (ADL) measures: five of 18 nursing therapies; two of six drug therapies; six of eight tracers. There was some reduction in hospital admissions and total days in geriatric NP homes. Overall measures of medical attention showed a mixed pattern with some evidence of geriatric NP care substituted for physician care. These findings suggest that the geriatric NP has a useful role in nursing home care.

Risk selection of families electing HMO membership.

This study analyzes the health plan selection history of approximately 30,000 employees of a large aerospace corporation. The data show that families selecting HMOs were younger, had lower income, and had less time on the job. HMOs attracted families with lower annual claimed expenditures, and these families' claimed expenses were lower still in the year immediately prior to switching into the HMO. Lower costs among families switching into the HMOs are partly explained by the composition of these families compared with families who stayed in the FFS plan. However, the selection pattern persisted even after adjusting for the size of the family, the age and sex of family members, and other family characteristics, such as race and income. Families switching out of HMOs had higher total annual claims during their first year back in the FFS sector compared with families about to switch into HMOs. However, recent HMO exiters did not always differ from families who never left the FFS plan.

Scale and structure of capitated physician organizations in California.

Physician organizations in California broke new ground in the 1980s by accepting capitated contracts and taking on utilization management functions. In this paper we present new data that document the scale, structure, and vertical affiliations of physician organizations that accept capitation in California. We provide information on capitated enrollment, the share of revenue derived by physician organizations from capitation contracts, and the scope of risk sharing with health maintenance organizations (HMOs). Capitation contracts and risk sharing dominate payment arrangements with HMOs. Physician organizations appear to have responded to capitation by affiliating with hospitals and management companies, adopting hybrid organizational structures, and consolidating into larger entities.

How will changes in health insurance tax policy and employer health plan contributions affect access to health care and health care costs?

OBJECTIVE: To understand how changes in federal taxation of and employer contributions to health insurance benefits affect the decisions of firms to offer insurance, the willingness of households to purchase different health plans, and the resultant health expenditures. DESIGN: Economic policy simulation. SETTING: Secondary data analysis. PARTICIPANTS: A total of 18,343 sampled families (representing 77 million total families throughout the United States) with a working household head from the 1988 Current Population Survey who were not covered by either Medicare, Medicaid, or CHAMPUS (Civilian Health and Medical Program of the Uniformed Services) insurance. INTERVENTIONS: One intervention limits the amounts of tax-free employer contributions to health insurance premiums to 80% of our estimate of the base plan in the market and assumes that employer contributions will also be limited to this maximum. A second intervention eliminates the favorable tax treatment of employer-paid premiums altogether and assumes that employees will pay the full price of insurance. MAIN OUTCOME MEASURES: Change in the number of working families offered employment-based insurance, change in insurance plan choice, and change in medical spending. RESULTS: Capping the favorable tax treatment and employer contributions decreases the number of families offered employment-based insurance by approximately 91,000, increases the number of families selecting the least generous insurance plan from 20% under the current situation to 33%, and reduces overall health spending by less than 2%. By eliminating the tax exemption altogether, the number of families offered employment-based insurance decreases by approximately half a million families, the number of families selecting the least generous plan goes from 20% to 40%, and overall spending falls by about $16 billion. CONCLUSIONS: Eliminating the tax subsidy and limiting employer-paid contributions to the low-cost plan substantially increases the number of low-income uninsured under a voluntary insurance system, decreases overall spending only modestly, but would raise tax revenues by $36 billion. These tax revenues could be used to assist low-income families to obtain insurance coverage.
