Relationship of hospital-associated bleeding with length of stay and total hospitalization costs in patients hospitalized for atrial fibrillation.

Background: While literature has focused on the impact of bleeding beginning outside the hospital setting among patients with atrial fibrillation (AF), there is little information regarding bleeding that first occurs within a hospital setting. This study was performed to determine the association between hospital-associated bleeding in patients admitted for AF on outcomes of length of stay (LOS) and total hospitalization cost.

Methods And Results: The Premier research database was queried to identify adult inpatients discharged between 2008-2011 having a primary diagnosis code for AF where a bleeding diagnosis code was not present on admission.
