Is Same-Hospital Readmission Rate a Good Surrogate for All-Hospital Readmission Rate?
Key result
Same-hospital readmission rates captured only 80.9% of all heart failure readmissions, with a mean difference of 4.7% compared to all-hospital rates, making it an unreliable surrogate.
Why the study?

Implication
Same-hospital readmission rates may not reliably proxy all-hospital rates; leaves open their use as quality benchmarks.

Main Result
Mean Difference: 4.7
Same-hospital readmission rate is an unreliable and biased surrogate for all-hospital readmission rate, limiting its value as a benchmark for quality of care.

Nasir et al. (2010) conducted an observational in Heart failure (n=501,234). Same-hospital readmission rate vs. All-hospital readmission rate was evaluated on 30-day risk-standardized readmission rates (RSRRs) (MD 4.7%). Same-hospital readmission rates captured only 80.9% of all heart failure readmissions, with a mean difference of 4.7% compared to all-hospital rates, making it an unreliable surrogate.
