The results are expressed in median (IQR) where appropriate. P values, describing comparison with 2014 preintervention year, were calculated using a Wilcoxon sum rank for non-parametric data and chi-square for categorical data. Statistical significance was set at p<0.05. Significant results are highlighted in bold.
*Patients were included from 1 April 2014 to 31 December 2014.
†Patients were included from 1 January 2018 to 30 September 2018.
