Implementing target range oxygen in critical care: A quality improvement pilot study.

Background: Iatrogenic hyperoxaemia is common on critical care units and has been associated with increased mortality. We commenced a quality improvement pilot study to analyse the views and practice of critical care staff regarding oxygen therapy and to change practice to ensure that all patients have a prescribed target oxygen saturation range.

Methods: A baseline measurement of oxygen target range prescribing was undertaken alongside a survey of staff attitudes.

Relatively speaking: contrast effects influence assessors' scores and narrative feedback.

Context: In prior research, the scores assessors assign can be biased away from the standard of preceding performances (i.e. 'contrast effects' occur).
