Effect of oral intake initiation-establishment interval on hospital stay after oral cancer surgery.

Abstract

To clarify the effect of the period between initiation of oral intake (IOI) and establishment of oral intake (EOI) on length of hospital stay. This retrospective study included postoperative oral cancer patients. The number of days from surgery to IOI and EOI and between IOI and EOI were recorded. We performed intergroup comparisons and Cox regression analysis using the number of days until discharge, representing hospital stay length as the dependent variable. The median number of days between IOI and EOI was 3 days for eligible patients and 4.5 and 1.5 for older and younger patients, respectively. The median number of days from surgery to IOI was 15 days. There was a significant correlation between the period between IOI and EOI and the length of hospital stay (r = 0.40, p < 0.01). The period between IOI and EOI was a significant independent variable for the length of hospital stay (HR [95% confidence interval] = 0.45 [0.28-0.72]). Shortening the IOI to EOI intervals was identified as an independently associated factor for shortening hospital stay, even in older postoperative patients with dysphagia who struggled with early oral intake initiation. Professional, step-by-step dysphagia rehabilitation tailored to the patient's condition yields beneficial outcomes.
