Validation of a novel claims-based stroke severity index in patients with intracerebral hemorrhage.

摘要: Abstract Background Stroke severity is an important outcome predictor for intracerebral hemorrhage (ICH) but typically unavailable in administrative claims data. We validated a claims-based stroke index (SSI) patients with ICH Taiwan. Methods Consecutive from hospital-based registries were linked nationwide database. severity, assessed using the National Institutes of Health Scale (NIHSS), and functional outcomes, modified Rankin (mRS), obtained registries. The SSI was calculated based on billing codes each patient's claims. two types criterion-related validity (concurrent predictive validity) by correlating NIHSS mRS. Logistic regression models or without as continuous covariate fitted to predict mortality at 3, 6, 12 months. Results concurrent established its significant correlation admission (r = 0.731; 95% confidence interval [CI], 0.705–0.755), verified correlations 3-month (r = 0.696; CI, 0.665–0.724), 6-month (r = 0.685; 0.653–0.715) 1-year (r = 0.664; 0.622–0.702) Mortality had highest area under receiver operating characteristic curve, followed any marker severity. Conclusions appears be valid proxy effective adjustment studies
