Background: The prevalance of Atrial fibrillation (AF) is approaching epidemic proportions and is associated with significant clinical and public health care burden. Not much work however is done to risk stratify AF patients during their hospital stay with regards to length of stay (LOS) and cost of care.
Methods: HCUP's National Readmission Data (NRD) 2013, sponsored by AHRQ was querried for AF admissions using ICD 9 CM code 427.31 in principal diagnosis field. CHADS2 and CHA2DS2VASc scores were calculated for each patient. Hierarchical two level multivariate models were used to evaluate study outcomes of LOS and cost.
Results: During the study year, 128,468 (43.63% age≥75 years and 51.06% female) patients were hospitalized with a principal diagnosis of AF. In univariate analysis, LOS progressively increased from 2.37days for CHADS2 score of zero to 5.75 days for score of six while cost of care increased from $8299 to $13015. CHA2DS2VASc scoring similarly demonstrated a trend towards increasing LOS and increasing cost of care for higher scores (Figure 1). In our multivariate models, CHA2DS2VASc but not CHADS2 was able to predict increasing LOS and increasing cost of care through all score levels.
Conclusions: CHADS2 and CHA2DS2VASc scores represent clustering of risk factors that could be used to predict outcomes beyond thromboembolic risk. Physician familiarity with these scoring systems make them easy to use bedside clinical tools for resource allocation.
