RESUMEN
OBJECTIVE: To assess initial changes in home health patient outcomes under Medicare's home health Prospective Payment System (PPS), implemented by the Centers for Medicare and Medicaid Services (CMS) in October 2000. DATA SOURCES/STUDY SETTING: Pre-PPS and early PPS data were obtained from CMS Outcome and Assessment Information Set (OASIS) and Medicare claims files. STUDY DESIGN: Regression analysis was applied to national random samples (n=164,810) to estimate pre-PPS/PPS outcome and visit-per-episode changes. DATA COLLECTION/EXTRACTION METHODS: Outcome episodes were constructed from OASIS data and linked with Medicare claims data on visits. PRINCIPAL FINDINGS: Outcome changes (risk adjusted) were mixed and generally modest. Favorable changes included higher improvement rates under PPS for functioning and dyspnea, higher community discharge rates, and lower hospitalization and emergent care rates. Most stabilization (nonworsening) outcome rates also increased. However, improvement rates were lower under PPS for wounds, incontinence, and cognitive and emotional/behavioral outcomes. Total visits per episode (case-mix adjusted) declined 16.6 percent although therapy visits increased by 8.4 percent. CONCLUSIONS: The outcome and visit results suggest improved system efficiency under PPS (fewer visits, similar outcomes). However, declines in several improvement rates merit ongoing monitoring, as do subsequent (posthome health) hospitalization and emergent care use. Since only the early PPS period was examined, longer-term analyses are needed.

Post-acute care (PAC) occurs in a variety of settings-skilled nursing facilities (nursing homes), rehabilitation facilities, and home health agencies. To evaluate the impact of care processes on clinical outcomes and implement changes designed to improve outcomes, one must begin by measuring outcomes in a valid, reliable manner that allows for comparisons to reference or benchmarking data. Currently, several data sets exist in PAC settings for the purpose of outcome measurement. However, there is a need for comparable information across settings to ensure the quality and continuity of care. This article reviews various existing data sets used in PAC settings, examines ongoing projects to create a single set of measures, and suggests some directions for future research.

Using OASIS data collected by all Medicare-certified home health agencies, this article first presents descriptive statistics on patient outcomes for a national agency sample in 2001, soon after Medicare prospective payment implementation. Ratios of actual to predicted outcome rates, aggregated for groups of outcomes, are considered as potential summary indicators of agency outcome performance. The aggregate ratios show promise, but information on each outcome remains critical to agencies' outcome improvement efforts. Ratios for some outcomes are interrelated, suggesting that agencies focusing outcome enhancement efforts on a few target outcomes also may improve related outcomes.

Wide variation in Medicare home care utilization became apparent in the 1990s. This study examined the impact of patient, provider, agency, and market factors on five measures of home care practice. Data were collected at 44 agencies in eight states. The final analysis sample included 732 home care episodes for which longitudinal patient data were available. Results indicated that patient factors, such as complexity and functional status, were important predictors of the care a patient received. Agency and market characteristics also strongly influenced care practices. Characteristics of the care providers, on the other hand, exerted only minimal influence.

OBJECTIVES: To evaluate effects on patient outcomes of Outcome-Based Quality Improvement (OBQI), a continuous quality improvement methodology for home health care (HHC). DESIGN: A quasi-experimental design with prospective pre/post and study/control components within two multiyear demonstration trials (occurring from 1995 to 2000) in which 73 home health agencies implemented OBQI, receiving several annual cycles of outcome reports to evaluate and enhance patient outcomes. SETTING: New York and 27 other states. PARTICIPANTS: The study involved 157,548 predominantly older adult patients admitted over 3 years to 54 OBQI agencies from 27 states in the National Demonstration Trial, 105,917 patients admitted over 4 years to 19 OBQI agencies in the New York State Trial, and 248,621 patients admitted over 3 years to non-OBQI control agencies in the 27 demonstration states. INTERVENTION: As a clinical management and administrative intervention, OBQI involves collecting, encoding, and transmitting patient-level health status data to a central source that provides each OBQI agency with a risk-adjusted outcome report comparing the agency's patient outcomes with those from a reference population and with its own outcomes from the prior period. Target outcomes are selected and focused plans of action implemented to change care behaviors. Outcome changes are evaluated through the next report cycle. MEASUREMENTS: Outcome measures include hospitalization rates and improvement and stabilization outcome rates in functional, physiological, emotional/behavioral, and cognitive health. RESULTS: For the National and New York State Demonstration Trials, the risk-adjusted relative rates of decline in hospitalization of 22% and 26%, respectively, for OBQI patients over the 3-year and 4-year demonstration periods were significant (P <.001) and unparalleled by considerably smaller rates of decline for the non-OBQI patients in the 27 states. The risk-adjusted rates of improvement in OBQI target outcome measures of health status averaged 5% to 7% per year in both demonstration trials and were significantly greater (P <.05) than analogous improvement rates for nontarget comparison outcomes, which averaged about 1% per year. CONCLUSION: It is feasible to integrate the programmatic, data collection, data transmission, and outcome enhancement components of OBQI into the day-to-day operations of home health agencies. The aggregate findings and the agency-level evidence available from site-specific communications suggest that OBQI had a pervasive effect on outcome improvement for home health patients. OBQI appears to warrant expansion and refinement in HHC and experimentation in other healthcare settings.

This study arose from concerns that home health care may be more difficult to provide to rural than urban elderly patients (because of geographic barriers, personnel shortages, and other factors) and may therefore be less effective in terms of patient outcomes. Case mix, home health care service use, and outcomes (primarily discharge status) were analyzed for a national random sample of 3,869 rural and urban elderly home health patients. Longitudinal data covered the period from home health admission to discharge or 120 days (whichever occurred first). Primary data collection instruments were designed to obtain longitudinal patient-level health status data; agency records and Medicare data provided service use information. (The study did not address access but focused on services and outcomes after admission to home health care.) Two-group statistical tests and multivariate analyses were employed to assess rural-urban differences. The major findings were that, after adjustment for rural-urban case mix and agency differences, rural compared to urban patients received fewer home health services and attained less favorable discharge outcomes. For example, the rural patients had a higher case mix adjusted hospitalization rate. Because the study data pertain to 1995 through 1996, the results provide a baseline for future analyses of possibly different rural compared to urban effects of the Balanced Budget Act of 1997, which resulted in major changes in Medicare payment for home health care.
