Impact of Preoperative Risk Factors on Inpatient Stay and Facility Discharge After Free Flap Reconstruction

To determine the preoperative risk factors most predictive of prolonged length of stay (LOS) or admission to a skilled nursing facility (SNF) or inpatient rehabilitation center (IPR) after free flap reconstruction of the head and neck.Retrospective cohort study.Tertiary academic medical center.Retrospective review of 1008 patients who underwent tumor resection and free flap reconstruction of the head and neck at a tertiary referral center from 2002 to 2019.Of 1008 patients (65.7% male; mean age of 61.4 years, SD 14.0 years), 161 (15.6%) were discharged to SNF/IPR, and the median LOS was 7 days. In multiple linear regression analysis, Charlson Comorbidity Index (CCI;Common tools for assessing frailty and need for additional care may be inadequate in a head and neck reconstructive population. CCI appears to be the best of the aggregate metrics assessed, with significant relationships to both LOS and placement in SNF/IPR.
