Factors associated with utilisation of health care interpreting services and the impact on length of stay and cost: A retrospective cohort analysis of audit data.

Approximately half of those who required an interpreter received one during their hospital stay. Further investigation is needed to establish whether regular clinical audits contributed to this rate of utilisation, which is higher than reported elsewhere in the literature. SO WHAT?: A detailed understanding of regional interpreting service use with evidence from the literature provides compelling and contextual evidence for change, at the level at which the service is delivered. This supports meaningful action to increase utilisation, and improve the quality and safety of health care delivered to patients with limited English proficiency.
