  1. Does Information Matter? Competition, Quality and the Impact of Nursing Home Report Cards David C. Grabowski, Harvard Robert Town, Minnesota and NBER AcademyHealth, June 2008

  2. Background • Nursing home quality is an important policy issue • One explanation for poor NH quality is incomplete information • Both the federal government and some states have adopted NH report cards in recent years

  3. Nursing Home Compare

  4. NH Compare (cont.) • Almost no evidence of NH Compare use pre-2002 • Also no evidence of state report card use • However, NHQI was strongly promoted: • Media campaign of television and newspaper ads • QIOs promoted awareness among NHs • State LTC Ombusman promoted awareness among consumers • Monthly website visits on NH Compare jumped from 100,000 to 400,000

  5. Mukamel et al (2008) examined trends in 5 QMs pre/post NHQI and found 2 QMs (restraints, pain) showed a small one-time improvement Several specific actions by NHs were associated with this improvement Previous Literature Mukamel et al (2008), Health Services Research

  6. Our Contribution • Examine impact of NH Compare on quality • Given national introduction, we rely on differences in NH market structure to identify our model • The more competitive the market, the more the flow of residents are affected by report card information

  7. Data • MDS Facility Reports: 1999-2005q1 • QI/QM data at facility-level by quarter • OSCAR: 1999-2004 • Staffing • Health-related deficiencies • Facility characteristics (ownership, size, etc.)

  8. General Empirical Approach NH fixed effects model Yist = β(NHCst*HHIi) +γXist + i + λt + εist Where: Yist is quality for NH i in state s of quater t NHCst is an indicator for the NH Compare HHIi is competition at baseline, defined by fixed 25km radius Xist is a set of NH level control variables i = NH fixed effects λt = quarter fixed effects εist is a randomly distributed error term

  9. Independent Variables Xist encompasses: • Size dummies • Ownership status (for-profit, NFP, government) • Hospital affiliation • Whether part of multiple-facility chain • Average # ADLs with which residents need assistance

  10. Methods • For outcomes expressed as % of residents, use logit transformation so dependent variables are of form: • For staffing, use OLS • For deficiencies, use negative binomial model • Huber-White std errors, clustered by NH

  11. Impact of Initial NH Compare Introduction

  12. Impact of NHQI

  13. Magnitude of Estimates • Change in HHI between 0.5 and 0.2 on the percentage change in the SD of the QI • Depression = 48% • ADL Loss = 4% • Pressure ulcers, high risk = 22% • Pressure ulcers, low risk = 105% • Incontinence = 9%

  14. Patient Flows • Further means of validating these quality results is to examine the effect of NHQI on market share • We would expect low quality NHs at baseline to lose market share and high quality NHs to gain market share • Thus, we regress ln(market share) on NHQI*baseline quality

  15. Effect of NHQI*Baseline Quality on Market Share

  16. Summary of Results • Initial CMS report card efforts had little effect on NH quality • Subsequent, better publicized efforts did improve quality across certain measures • Some limited evidence that higher quality NHs gained some market share post-NHQI

  17. Implications • Report cards alone yield few benefits (!) • Unclear whether CMS has continued to monitor and encourage report card use following the NHQI • Effects are heterogeneous, suggesting some QMs may be more amenable to change • Nature of the QM and ability of providers to improve behavior • Competition associated with better outcomes • Intuitive but does not necessarily fit w/ the “conventional wisdom” in LTC
