Key result
The proportion of the emergency surgical workload taking place after midnight decreased significantly over the 7-year study period (r = -0.742, p < 0.01), though a consistent volume of complex cases still required night-time surgery.

Despite a decrease in the proportion of emergency operations performed at night, a consistent volume of complex cases still requires surgery after midnight, necessitating appropriate service provision.
Faiz et al. (2007) conducted an observational in Emergency general surgical and vascular conditions (n=5,316). Night-time emergency surgery vs. Daytime and evening emergency surgery was evaluated on Trend in the proportion of the emergency workload that took place after midnight over the study period (r = -0.742, p=< 0.01). The proportion of the emergency surgical workload taking place after midnight decreased significantly over the 7-year study period (r = -0.742, p < 0.01), though a consistent volume of complex cases still required night-time surgery.
