  • 53 month dummies included (April 2012 to September 2016) model controls for number of emergency attendances each month, observations are weighted by number of emergency attendances each month. A total of 117 trusts were followed for 6 months, 96 for 9 months, 83 for 12 month and 43 for 24 months. The longest follow-up period was for a single trust at 35 months.

  • Least-squares dummy variable model. Robust 95% CIs are within parentheses.

  • *P<0.05, **p<0.01, ***p<0.001.

  • ED, emergency department.
