Changes in the Relationship Between Nursing Home Financial Performance and Quality of Care Under Public Reporting Jeongyoung Park, Ph.D. Rachel M. Werner, MD. Ph.D. University of Pennsylvania Funded by AHRQ (R01-HS016478-01) AcademyHealth, June 8-10 2008
Background • Improving quality of nursing home care is a national priority • Over the past decade, the US nursing home industry has experienced severe financial pressure • Improving quality involves substantial production costs • Financial condition/stability becomes an important consideration in explaining quality variation AcademyHealth, June 8-10 2008
Prior Research • Yet nature of the relationship between financial performance and quality of care is not obvious • Two conflicting expectations • (-): Trade-off (Davis et al, 1998; O’Neil et al, 2003) • Profit-maximization • (+): Positive (Mukamel & Spector, 2000; Weech-Maldonado et al, 2003) • Market-wide change->more competitive • Market-based initiatives • Product differentiation strategy AcademyHealth, June 8-10 2008
Market-based Initiatives • Recent move toward market-based quality initiatives • Quality report cards • Nursing Home Compare (November, 2002) • Reallocating demand from low to high quality facilities • Generating indirect financial consequences by changing market shares • Pay-for-performance (P4P) • Currently in place or in planning stage • Direct financial incentives for high performance • Positive relationship between financial performance and quality will be stronger under new market and regulatory conditions AcademyHealth, June 8-10 2008
Research Questions/Hypotheses • How do quality report cards affect the relationship between nursing home financial performance and quality of care? • H1: Facilities with high profit are more likely to provide better quality of care after public reporting • To what extent is this relationship affected by facility or market characteristics? • H2: The extent of the impact is likely to be larger at for-profit facilities after public reporting • H3: The extent of the impact is likely to be larger in more competitive markets after public reporting AcademyHealth, June 8-10 2008
Data • Financial performance • Medicare Cost Report (MCR) • Quality and facility characteristics • Online Survey Certification and Reporting System (OSCAR) • Limited to freestanding skilled nursing facilities (SNFs) • 9,444 SNFs with 75,400 observations • FY 1997-2006 AcademyHealth, June 8-10 2008
Measures • Financial performance • Total profit margin t-1 • Total profit margin t-1 NHC • Quality measures • Staffing: Total staff hours per resident day (HPRD) • Outcome: Incidence rate of pressure sores • Process: Incidence rate of restraint use • Total deficiency citations AcademyHealth, June 8-10 2008
Analytic Strategy • Facility fixed-effects (FE) address omitted bias for time-invariant confounders • FE with instrumental variables approach (IV-FE) controls for potential endogeneity of financial performance • Two-stage equation models • Profit = f(X, IV, fixed effects) • Quality = f(X, Profit, fixed effect) • Instrumental variables • CMS hospital wage index t-1 • Total resident days t-1 • Total resident days t-1 NHC AcademyHealth, June 8-10 2008
Descriptive Results • For-profit: 72.2% • Nonprofit: 24.0% • Government: 3.8% • Chain: 61.0% • Occupancy rate: 84.4% • Total certified beds: 118 • % Medicaid: 65.0% • HHI: 0.27 • Total profit margin t-1: 1.1% • Total Staff HPRD: 2.97 • Incidence rates of • Pressure sores: 3.67% • Restraint use: 7.07% • Deficiencies: 5.75 Source: OSCAR and MCR (FY 1997-2006) AcademyHealth, June 8-10 2008
Results: Effect of Profit on Quality IRR=Incidence Rate Ratios **p<.01; *p<.05 AcademyHealth, June 8-10 2008
Table 4: Effect of total profit margin by ownership (IV-FE) Results: By Ownership IRR=Incidence Rate Ratios **p<.01; *p<.05 AcademyHealth, June 8-10 2008

Conclusions • Financial performance is an important determinant of the delivery of high quality care in post-NHC period • Variation in relationship exists • Effects are statistically significant, but modest in size on average • However, the effects are likely to be larger when direct financial payment is made for high quality performance (i.e., P4P) AcademyHealth, June 8-10 2008
Implication • Recent move toward wide-spread adoption of market-based quality improvement initiatives (i.e., NHC, P4P) may not substantially improve quality across all facilities • P4P may worsen both financial and quality disparities, if financial resources are necessary to achieve high quality of care • Proposed nursing home P4P should be carefully designed and managed AcademyHealth, June 8-10 2008
