Key result
Composite scores for acute ischemic stroke care showed higher rankability (84.03% of variance due to true quality differences) than individual indicators like rt-PA (49.51%) or independence (63.34%).
Why the study?
It was unclear to what extent different types of performance measures detect genuine differences in underlying care quality for hospital comparisons.
Population
15,090 acute ischemic stroke patients at 184 large tertiary hospitals

Composite scores may better capture true quality variation in stroke care; leaves open whether they should supplant individual metrics in practice or policy.
Observational (n=15,090)
Yes
Composite scores are more reliable and robust than individual process measures or clinical outcomes for ranking hospital quality of care in acute ischemic stroke.
Li et al. (2021) conducted an observational in acute ischemic stroke (n=15,090). Composite scores (CS) vs. Individual indicators (rt-PA) and in-hospital outcome (independence) was evaluated on Rankability (variance between hospitals due to true quality differences). Composite scores for acute ischemic stroke care showed higher rankability (84.03% of variance due to true quality differences) than individual indicators like rt-PA (49.51%) or independence (63.34%).
