Backgrounds: Data on risk factors for deep neck infection including descending necrotizing mediastinitis (DNM) have been limited. Using a nationwide database, the aim was identifying the factors related to patient death and delay in recovering oral intake.
Methods: Data of 4949 patients were extracted from a Japanese inpatient database between 2012 and 2017. The main outcome was survival at discharge. In a subgroup analysis of the 4949 patients with survival, the second outcome was delay in the interval between admission and full recovery of oral intake.
Results: Only a few factors (advanced-age, ventilation) were associated with both mortality and delayed oral dietary intake by logistic regression analyses. Conversely, several factors including DNM (adjusted-odds ratio [OR] 1.41) and repeated surgery (adjusted-OR 1.70) were significantly related only to delayed oral dietary intake.
Conclusions: Although DNM was not necessarily related to mortality, patients with DNM should receive careful attention to avoid delayed oral dietary intake.
