Both increases in the absolute number of elderly persons and in their longevity will increase future Medicare expenditures. Yet, the expected increase in per person health care expenditures caused by greater longevity of Medicare beneficiaries will be less than expected because of the concentration of expenditures at the end of life rather than during extra years of a relatively healthy life. The latter conclusion may be altered, however, because of other underlying considerations, such as technological change.

Objective. To assess longitudinally whether a change in registered nurse (RN) staffing and skill mix leads to a change in nursing home resident outcomes while controlling for the potential endogeneity of staffing. Data Sources. Minimum Data Set (MDS) nursing home resident assessment data from five states merged with Online Survey Certification and Reporting (OSCAR) data from 1996 through 2000. Study Design. Resident-level longitudinal analysis with facility fixed effects and instrumental variables. Outcomes studied are incidence of pressure sores and urinary tract infections. RN staffing was measured as the care hours per resident-day and skill mix was measured as RN staffing hours as a proportion of total staffing hours. Data Extraction Method. We use all quarterly MDS assessments that fall within 120 days of an annual OSCAR data point, resulting in 399,206 resident-level observations. Principal Findings. Controlling for endogeneity of staffing increases the estimated impact of staffing on outcomes in nursing homes. Greater RN staffing significantly decreases the likelihood of both adverse outcomes. Increasing skill mix only reduces the incidence of urinary tract infections. Conclusions. Research that fails to account for endogeneity of the staffing-outcomes relationship may underestimate the benefit from increased RN staffing. Increases in RN staffing are likely to reduce adverse outcomes in some nursing homes. More research using a broader array of instruments and a national sample would be beneficial.

Cost-effectiveness ratios usually appear as point estimates without confidence intervals, since the numerator and denominator are both stochastic and one cannot estimate the variance of the estimator exactly. The recent literature, however, stresses the importance of presenting confidence intervals for cost-effectiveness ratios in the analysis of health care programmes. This paper compares the use of several methods to obtain confidence intervals for the cost-effectiveness of a randomized intervention to increase the use of Medicaid's Early and Periodic Screening, Diagnosis and Treatment (EPSDT) programme. Comparisons of the intervals show that methods that account for skewness in the distribution of the ratio estimator may be substantially preferable in practice to methods that assume the cost-effectiveness ratio estimator is normally distributed. We show that non-parametric bootstrap methods that are mathematically less complex but computationally more rigorous result in confidence intervals that are similar to the intervals from a parametric method that adjusts for skewness in the distribution of the ratio. The analyses also show that the modest sample sizes needed to detect statistically significant effects in a randomized trial may result in confidence intervals for estimates of cost-effectiveness that are much wider than the boundaries obtained from deterministic sensitivity analyses. care programme^.^.^ These intervals are particularly important since we generally determine

Differences in process of care and resident characteristics by facility type highlight the importance of considering: (1) the adequacy of existing process measures for evaluating smaller facilities; (2) resident case-mix when comparing facility types and outcomes; and (3) the complexity of understanding the implication of the process of care, given the importance of person-environment fit. Work is continuing to clarify the role of RC/AL vis-à-vis NHs in our nation's system of residential long-term care.

Past empirical work has shown a negative relationship between the body mass index (BMI) and wages in most cases. We improve on this work by allowing the marginal effect of non-linear BMI groups to vary by gender, age, and type of interpersonal relationships required in each occupation. We use the National Longitudinal Survey of Youth 1979 (1982-1998). We find that the often-reported negative relationship between the BMI and wages is larger in occupations requiring interpersonal skills with presumably more social interactions. Also, the wage penalty increases as the respondents get older beyond their mid-twenties. We show that being overweight and obese penalizes the probability of employment across all race-gender subgroups except black women and men. Our results for the obesity-wage association can be explained by either consumers or employers having distaste for obese workers.

No single component defines "good" AL care. Predictors and outcomes are inconsistent, and effect sizes are small. Therefore, practice and policy should not focus narrowly on any one area or restrict the type of care-this being welcome news that supports diversity to accommodate individual preferences.

Nursing homes are the site of death for many elderly patients with incurable chronic illness, yet dying nursing home residents have limited access to palliative care and hospice. The probability that a nursing home will be the site of death increased from 18.7% in 1986 to 20.0% by 1993. Dying residents experience high rates of untreated pain and other symptoms. They and their family members are isolated from social and spiritual support. Hospice improves end-of-life care for dying nursing home residents by improving pain control, reducing hospitalization, and reducing use of tube feeding, but it is rarely used. For example, in 1997 only 13% of hospice enrollees were in nursing homes while 87% were in private homes, and 70% of nursing homes had no hospice patients. Hospice use varies by region, and rates of use are associated with nursing home administrators' attitudes toward hospice and contractual obligations. Current health policy discourages use of palliative care and hospice for dying nursing home residents. Quality standards and reimbursement rules provide incentives for restorative care and technologically intensive treatments rather than labor-intensive palliative care. Reimbursement incentives, contractual requirements, and concerns about health care fraud also limit its use. Changes in health policy, quality standards, and reimbursement incentives are essential to improve access to palliative care and hospice for dying nursing home residents. JAMA. 2000;284:2489-2494.

Objectives: Older patients discharged from the emergency department (ED) have difficulty comprehending discharge plans and are at high risk of adverse outcomes. The authors investigated whether a postdischarge telephone call-mediated intervention by a nurse would improve discharge care plan adherence, specifically by expediting post-ED visit physician follow-up appointments and/or compliance with medication changes. The second objectives were to determine if this telephone call intervention would reduce return ED visits and/or hospitalizations within 35 days of the index ED visit and to determine potential cost savings of this intervention.Methods: This was a 10-week randomized, controlled trial among patients aged 65 and older discharged to home from an academic ED. At 1 to 3 days after each patient's index ED visit, a trained nurse called intervention group patients to review discharge instructions and assist with discharge plan compliance; placebo call group patients received a patient satisfaction survey call, while the control group patients were not called. Data collection calls occurred at 5 to 8 days and 30 to 35 days after the index ED visits for all three groups. Chi-square or Fisher's exact tests were performed for categorical data and the Kruskal-Wallis test examined group differences in time to follow-up.Results: A total of 120 patients completed the study. Patients were 60% female and 72% white, with a mean age of 75 years (standard deviation [SD] AE 7.58 years). Intervention patients were more likely to follow up with medical providers within 5 days of their ED visits than either the placebo or the control group patients (54, 20, and 37%, respectively; p = 0.04). All groups performed well in medication acquisition and comprehension of medication indications and dosage. There were no differences in return visits to the ED or hospital within 35 days of the index ED visit for intervention patients, compared to placebo or control group patients (22, 33, and 27%, respectively; p = 0.41). An economic analysis showed an estimated 70% chance that this intervention would reduce total costs. Conclusions:Telephone call follow-up of older patients discharged from the ED resulted in expedited follow-up for patients with their primary care physicians. Further study is warranted to determine if
