Abstract: Introduction
The aim of our study was to investigate time trend in atrial fibrillation
(AF) related hospitalization and the cost of hospitalization over the
last decade in the United States and make projections for 2020.
The Nationwide Inpatient Sample database was used to estimate the annual
number and prevalence of hospitalizations with AF from 1998-2010.
Identification of AF-related hospitalizations was based on the
designation of the International Classification of Diseases (9th Edition)
Clinical Modification (ICD-9-CM) diagnosis code 427.31 (AF) as the
principal discharge diagnosis.
There were total 4,676,758 AF related hospitalizations from 1998-2010 in
the US. The relative percentage increase in hospitalizations from 1998 to 2010 was 46%. We used exponential model to identify the trend (R2=0.88).
Assuming a similar trend in AF hospitalization over next decade, 541,000 hospitalizations can be expected in 2020 (28% relative increment from
2010). The cost of hospitalization follows a linear trend (R2=0.98) and
is expected to rise by 55% in 2020 as compared to cost of care in 2010.
These data indicate that AF related hospitalizations and the cost of care
has increase tremendously over the last decade and is likely to pose a
large public health burden in the future.
