We aimed to appraise the evidence relating to the measurement properties of unidimensional tools to quantify pain after surgery. Furthermore, we wished to identify the tools used to assess interference of pain with functional recovery. ⋯ PROSPERO CRD42020213495.

Quantitative pupillometry is recommended for neuroprognostication after out-of-hospital cardiac arrest 72 h or more after ICU admission, but the feasibility and utility of earlier assessment is unknown. ⋯ Quantitative pupillometry within 6 h of ICU admission after out-of-hospital cardiac arrest may identify patients with a very low chance of neurologically intact survival. Further studies of early quantitative pupillometry in this population are warranted.

Editorial Comment Review
Case duration prediction and estimating time remaining in ongoing cases.
In this issue of the British Journal of Anaesthesia, Jiao and colleagues applied a neural network model for surgical case durations to predict the operating room times remaining for ongoing anaesthetics. We review estimation of case durations before each case starts, showing why their scientific focus is useful. ⋯ Most cases have few or no historical data for the scheduled procedures. Generalizability of observational results such as theirs, and automatic computer assisted clinical and managerial decision-making, are both facilitated by using structured vocabularies when analysing surgical procedures.

Randomized Controlled Trial
Randomised open-label trial comparing intravenous iron and an erythropoiesis-stimulating agent versus oral iron to treat preoperative anaemia in cardiac surgery (INITIATE trial).
Preoperative anaemia is a risk factor for adverse postoperative outcomes after cardiac surgery. Iron deficiency is a frequent cause of low preoperative haemoglobin. An effective treatment for preoperative anaemia associated with iron deficiency has not been determined. ⋯ ISRCTN Number: 41421863; EUDRACT number: 2011-003695-36.
