The National Patient Safety Agency (NPSA) identified practice improvements with regard to epidural injections and infusions and released a patient safety alert on 28th March 2007. Prior to this, the Obstetric Anaesthetists' Association had considered the draft document and wished to assess current compliance in UK obstetric units. A postal survey of consultant-led obstetric anaesthetic units in the UK was performed in September 2006 to look at practice prior to the release of the safety alert. The response rate was 89%. Many units are already following the guidance from the NPSA but nearly one in four units have experience of wrong route drug errors related to confusion between systems for intravenous and regional drug administration.
