Background: Acute appendicitis is increasingly being managed in the setting of a dedicated emergency theatre. However understanding of hospital factors that influence time-to-theatre (TTT) is poor. Thus, the aim of this study is to identify factors that influence TTT and to observe the effect of prolonged TTT on patient outcome. Methods: A retrospective review of an electronic prospectively maintained database was performed over a 2 year period. Factors thought to influence TTT were highlighted. A delay was defined as TTT &gt; 8 hours. Data analysis was performed using SPSS 20. Results: 1,000 cases of suspected acute appendicitis were identified. Median age was 19 years. Appendicectomy was performed in 90.7%. 68.1% underwent laparoscopic appendicectomy. Overall mean TTT was 12 hours, 27 minutes. There was a significant association between delayed TTT and female gender (p = 0.017), older age (p = 0.001), pre-operative radiology (&lt; 0.001), normal WCC (p &lt; 0.001), normal neutrophils (p &lt; 0.001) and histological non-perforated appendix (p &lt; 0.001). However, on multivariate analysis, younger age, a neutrophilia and presence of a perforation had a shorter TTT. Delayed TTT did not affect outcome variables including post-operative collection (3.59% v 4.38%, p = 0.528), readmission rate (6.54% v 5.72%, p = 0.403) and length of stay (3.1 days v 3.34 days, p = 0.823). Conclusions: This study highlights key hospital factors that influence TTT in patients with suspected appendicitis. Identification of these influential factors adds greatly to our understanding of patient prioritisation. Finally, TTT delays greater than 8 hour do not appear to affect short-term patient outcomes.
