Background: The understanding of hospitalization fever remains limited. Improving care could be facilitated by considering specific diseases associated with fevers, as indicated by ICD9 codes in admission or discharge notes.
Methods: We conducted an analysis using data from Taipei medical university hospital, examining 59,772 inpatient admissions and 425,488 nights of stay annually between 2007 and 2009. Decision tree and rule induction techniques were employed to characterize fever related diseases during hospitalization. Association rules were generated to suggest and validate comorbidities beyond those related to fever.
Conclusions: Throughout the three years period, fever consistently ranked as the most frequent ICD9 code in inpatient health records, including admission and discharge notes, accounting for over 25% of the top six most common codes. Our study illustrated the diseases associated with fever and their comorbidities. Notably, 81.193% of fever related ICD9 codes occurred fewer than 14 times, and the association rules for fever related comorbidities improved care with a 48.077% coverage rate through appropriate CPOE implementation.
