Venous thromboembolism among elderly patients treated with atypical and conventional antipsychotic agents.

BACKGROUND: Some antipsychotic agents have been indicated as a possible risk factor for venous thromboembolism (VTE) in adult patients with psychiatric disorders. The aim of this study was to estimate the effect of atypical and conventional antipsychotic agents on the risk of hospitalization for VTE among elderly patients. METHODS: We conducted a retrospective cohort study on nursing home residents in 5 states. We used data from the Minimum Data Set to identify 19 940 new users of antipsychotic agents and 112 078 nonusers. Hospitalization with VTE as primary discharge diagnosis was determined during a 6-month follow-up period using Medicare inpatient claims. Cox proportional hazards models provided estimates of effect adjusted for confounders. RESULTS: The rate of hospitalization for VTE was 0.91 per 100 person-years. Venous thrombosis accounted for 77.6% of events and 22.4% were pulmonary embolisms. Relative to nonusers, the rate of hospitalization for VTE was increased for users of atypical antipsychotic agents, including risperidone (adjusted hazard ratio [HR], 1.98; 95% confidence interval [CI], 1.40-2.78), olanzapine (adjusted HR, 1.87; 95% CI, 1.06-3.27), and clozapine and quetiapine fumarate (adjusted HR, 2.68; 95% CI, 1.15-6.28). No increased rate was associated with phenothiazines (adjusted HR, 1.03; 95% CI, 0.60-1.77) or other conventional agents (adjusted HR, 0.98; 95% CI, 0.52-1.87). CONCLUSIONS: Atypical antipsychotic agents appear to increase the risk of VTE. However, these events are rare, and in clinical practice the absolute risk should be weighed against the effectiveness of these medications in the elderly population.

Physician and nurse staffing in nursing homes: the role and limitations of the Online Survey Certification and Reporting (OSCAR) system.

OBJECTIVES: To assess nursing home staffing data reported in the Online Survey Certification and Reporting (OSCAR) system database for research and policy. DESIGN: Comparisons were made between OSCAR and a concurrent research survey of staffing data collected for the same facilities, using inter-rater agreement and correlation analyses. SETTING: Freestanding nursing homes from New York State (NYS) in 1997 (N = 327). MEASUREMENTS: Selected staffing variables were defined in comparable terms in both OSCAR and the NYS survey. RESULTS: The two data sources were in substantial agreement on the reported availability of a full-time physician (other than medical director) and of a physician assistant or nurse practitioner (Kappa >0.7), and they correlated well in the full-time equivalent (FTE) number of such staff (Spearman correlation >0.6). The correlation was 0.8 for FTE registered nurses (RNs), 0.7 for licensed practical nurses (LPNs), and 0.8 for certified nurse aides (CNAs). In terms of average nurse hours per patient day, separately for RNs, LPNs, CNAs, and all combined, the correlation was relatively weak (between 0.3 and 0.6). Overall staffing levels tended to be lower in OSCAR than in NYS. CONCLUSION: The OSCAR data are useful for exploring relationships between staffing and various quality of care outcomes, but may not be accurate enough on a case-specific basis, or to determine policy regarding minimal staffing levels using average nurse hours per patient day measures. More systematic and timely efforts are needed to refine the OSCAR content and survey methodology to document nursing home staffing information.

A structure-technology contingency analysis of caregiving in nursing facilities.

The purpose of this paper is to describe how the work associated with psychosocial and physical caregiving is structured within nursing facilities. Arguing from a contingency perspective, our central hypothesis is that because the technology underlying physical care is less variable and more interpretable and the process-outcome relationships underlying care processes are better understood than for psychosocial care, work in the physical care domain will be comparatively more mechanistically structured even though work in both domains is performed by the same paraprofessional nurse aide staff. Data for this analysis derive from a survey of unit charge nurses (n = 739) in 308 nursing homes in eight states undertaken as part of a large NIA-funded study of the relationship between nursing home organization and resident outcomes. With the exception of centralization, contingency theory correctly predicts how the work associated with physical and psychosocial care is differentiated.

The relationship between quality of care and costs in nursing homes.

The purpose of this study was to evaluate the impact of quality of care on costs in nursing homes. The sample consisted of 749 nursing homes in 5 states in 1996. Nursing home cost functions were estimated using weighted 2-stage least-squares regression analysis. Costs are measured as the facility's total patient care costs. Two outcome measures are used as quality indicators: pressure ulcers worsening and mood decline. Nonmonotonic relationships are observed between quality and costs for nursing homes in the sample. However, the pattern of the relationship is different depending on the quality indicator. For pressure ulcers, the authors observe an inverted U-shaped curve with increasing costs at the lower range of quality but decreasing costs associated with higher quality after a threshold. The opposite pattern is observed for mood decline, with a relatively flat curve at the lower range of quality but increasing costs after a threshold.

Access to postacute nursing home care before and after the BBA. Balanced Budget Act.

Anecdotal reports in the wake of the Balanced Budget Act (BBA) of 1997 raised concerns about restricted access to postacute nursing facility care for Medicare beneficiaries requiring costly, medically complex services. Using all Medicare Part A hospital and nursing facility claims for providers in the state of Ohio and a refined method of identifying hospitalized beneficiaries who were the most at risk, we observed only a small decrease in the proportion of the costliest patients discharged to nursing facilities in 1999 compared with pre-BBA years. Average hospital length-of-stay increased only slightly in 1999, and there were no changes in rehospitalization rates for the costliest patient types. However, reduced rates of admission were concentrated in specific types of nursing facilities, suggesting a need to closely monitor the effects of ongoing post-BBA policy updates.

Medicaid payment and risk-adjusted nursing home quality measures.

Various studies have observed low quality in the nursing home industry. Although Medicaid is the dominant payer of U.S. nursing home services, the association of Medicaid payment rates and quality is not entirely clear, in part because resident-level, risk-adjusted information on quality is lacking. This study examined the relationship between Medicaid payment rates and three risk-adjusted quality measures, controlling for market and facility characteristics. Higher payment was associated with lower incidence of pressure ulcers and physical restraints but not daily pain. Quality of nursing home care may suffer if budget shortfalls force state legislatures to freeze or reduce Medicaid rates.

Recent trends in state nursing home payment policies.

State Medicaid programs pay for a sizable portion of overall nursing home expenditures. The repeal of the Boren amendment in 1997 gave states greater freedom to set Medicaid nursing home policy. This study presents data from a comprehensive survey of state nursing home payment policies during 1999-2002. Aggregate inflation-adjusted Medicaid payment rates rose steadily, and there was no sizable increase in the adoption of other cost-cutting policies. Although these findings can be interpreted with some optimism from a nursing home financing perspective, areas of concern remain for state nursing home policy during the next several years.
