Closing the audit cycle: improving short-term outcomes of oesophagectomy in a provincial hospital

A previously published study regarding the outcomes of oesophagectomy at a provincial hospital identified issues with perioperative care (Al-Herz et al 2012). The aim of this study was to evaluate the effect of changes in management at the institution concerned. This was a cohort study which compared the outcomes of 30 patients undergoing oesophagectomy before the unit audit and 30 patients after it. Demographics, operative details, recovery parameters, and oncological data were collected retrospectively. There was a significant reduction in the use of intravenous fluid, both intraoperatively (6.6 vs 3.3L, P < 0.0001) and during the first 24 hours (9.2 vs 5.5L, P < 0.0001). Patients were extubated three days earlier (P < 0.001) after the audit, and the percentage of patients requiring tracheostomy was smaller (26.7% vs 0%, P = 0.003). The length of total hospital stay was shorter (15 vs 13 days, P = 0.035). We conclude that the publication of a unit audit changed perioperative practice and resulted in a significant improvement in the short term outcomes after oesophagectomy.
