Hospitalizations with a primary diagnosis of BD were selected based on International Classification of Diseases version 9, Clinical Modification (ICD-9-CM) codes of diagnosis 296.xx (excluding 296.2x; 296.3x and 296.9x).</jats:p></jats:sec><jats:sec id="S0924933821002340_sec184" sec-type="results"><jats:title>Results</jats:title><jats:p>A total of 20,807 hospitalizations were registered belonging to 13,300 patients. 33.4% of the hospitalizations occurred in male patients and the median LoS was 16.0 days. Mean age was 47.9 years and male patients were younger(46.6 vs. 48.6; p< 0.001). 59 hospitalizations had a deadly outcome (0.3%). The most common cause of hospitalization in BD was the diagnosis code 296.4x (Bipolar I disorder, most recent episode (or current) manic) representing 34.3% of all hospitalizations, followed by the code 296.5x (Bipolar I disorder, most recent episode (or current) depressed) with 21.4%. The mean hospitalization charges were 3,508.5¤ per episode, with a total charge of 73M¤ in the 8-year period of this study.</jats:p></jats:sec><jats:sec id="S0924933821002340_sec185" sec-type="conclusions"><jats:title>Conclusions</jats:title><jats:p>This is a nationwide study using BigData analysis giving a broad perspective of BD hospitalization panorama at a nationwide level. We found differences in hospitalization characteristics by gender, age and primary diagnosis.</jats:p></jats:sec><jats:sec id="S0924933821002340_sec186"><jats:title>Disclosure</jats:title><jats:p>No significant relationships.</jats:p></jats:sec>
