Comparison of corticosteroid use between ICU physicians and the RL agent. Use of corticosteroids as percentage of patients receiving corticosteroids (a) and average cortisone dose (b) is compared between the historic treatment in the ICU and the RL policy after adjusting for the ICU length of stay. Both ICU physicians and the RL agent tend to prescribe corticosteroids during the early phase of the septic episode. Notably, the RL policy is more restrictive compared to the actual treatment the patients received.
