Abstract

Context The Leapfrog Hospital Survey allows hospitals to self-report the steps they have taken toward implementing the Safe Practices for Better Healthcare endorsed by the National Quality Forum. The Leapfrog Group currently ranks hospital performance on the safe practices initiative by quartiles and presents this information to the public on its Web site. It is unknown how well a hospital's resulting Safe Practices Score (SPS) correlates with outcomes such as inpatient mortality. Objective To determine the relationship between hospitals' SPSs and risk-adjusted inpatient mortality rates.Design, Setting, and Participants Observational analysis of discharge data for all urban US hospitals completing the 2006 safe practices initiative and identifiable in the Nationwide Inpatient Sample. Leapfrog provided an SPS for each hospital as well as 3 alternative scores based on shorter versions of the original survey. Hierarchical logistic regression was used to determine the relationship between quartiles of SPS and risk-adjusted inpatient mortality, after adjusting for hospital discharge volume and teaching status. Subgroup analyses were performed using data from patients older than 65 years and patients with 5% or greater expected mortality risk. Main Outcome Measures Inpatient risk-adjusted mortality by quartiles of survey score. Results Of 1075 hospitals completing the 2006 Safe Practices Survey, 155 (14%) were identifiable in the National InpatientSample (1 772 064 discharges). Raw observed mortality in the primary sample was 2.09%. Fully adjusted mortality rates by quartile of SPS, from lowest to highest, were 1.97% (95% confidence interval [CI], 1.78%-2.18%), 2.04% (95% CI, 1.84%-2.25%), 1.96% (95% CI, 1.77%-2.16%),and2.00% (95% CI, 1.80%- 2.22%) (P =.99 for linear trend). Results were similar in the subgroup analyses. None of the 3 alternative survey scores was associated with risk-adjusted inpatient mortality, although P values for linear trends were lower (.80.20, and 11).Conclusion In this sample of hospitals that completed the 2006 Safe Practices Survey, survey scores were not significantly associated with risk-adjusted inpatient mortality.
