Drivers of Hospitalization for Patients With AF
The data for this analysis are derived from an observational cohort of patients in clinical practice with known AF and thus subject to the limitations inherent therein, including sampling and/or reporting biases. Furthermore, conclusions regarding hospitalization cause are limited in that the broad categories are investigator assigned and data regarding urgency of admission (elective, emergent) are not available. Residual measured or unmeasured confounding may influence some or all of these findings. Finally, although the ORBIT-AF registry was inclusive, this population is older (consistent with the epidemiology of AF in the United States) and overwhelmingly white (90%). Accordingly, these data may not be entirely generalizable to younger patients, minority populations, or patients cared for in settings that differ from those represented in ORBIT-AF.
