    A limitation of the study was the recording of the discharge date as a single endpoint. We did not record the “medically fit for discharge” date to account for whether discharge was delayed for social reasons. Audits that show stays that are longer than expected for reasons other than surgical per-formance will potentially support the development of better discharge pathways.
    This study has shown that it is possible to MDMB-FUBINACA M 1 the assess-ment of a unit’s performance on length of stay because it adjusts for case mix and complexity of operation. The deci-sion tree algorithm accurately predicts for a stay of more than 15 days. The logistic regression algorithm allows for the comparison between units of patients who stay in hospi-tal for less than 15 days. Further work needs to be done before these socioeconomic data can be added to the models. It is conceivable that centres that treat patients with SCC of the head and neck can use such models to show safe standards of care in routine audits of outcome.

    Conflict of interest
    This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. The lead author is employed at Site 6, East Kent University Hospitals NHS Foundation Trust.
    Ethics statement/confirmation of patients’ permission
    This audit was registered at each audit department of the respective hospitals. As the culmination of this study could potentially be generalised, ethics approval was obtained from the EKHUFT, Grey Area Project Group, Research and Inno-vation Department.
