This is the protocol for a review and there is no abstract. The objectives are as follows:
We aim to assess the effect of the lateral position compared to other body positions on patient outcomes (mortality, morbidity and clinical adverse events during and following positioning) in critically ill adult patients. We will examine the single use of the lateral position (that is on the right or left side) and repeat use of the lateral position(s) in a positioning schedule (that is lateral positioning). We plan to undertake subgroup analysis for primary disease and condition, severity of illness, the presence of assisted ventilation and angle of lateral rotation.
