To examine the impact made on safe surgical practice by the introduction of correct site surgery documentation in a children’s hospital containing a surgical unit in South Yorkshire. A retrospective audit of randomly selected case notes of children attending the hospital for an ENT/Plastic surgery/Orthopaedic/General surgical procedure during a period in 2006 or 2008. Outcome measures included the total, correct and legible completion of correct site surgery documentation pre-operatively. Significant improvement was noted between the 2006 and 2008 audits in the amount of patients being correctly marked (33% vs. 91%), however there were no forms in either study that were fully and correctly completed. Legibility of the forms also improved markedly between the studies (33% vs. 98%). The completion of correct site surgery forms improved with greater publicisation of the forms, however the practicality of the numbers of people required to complete the forms needs to be reviewed. The international introduction of such forms will generate valuable data as to the future utility of these checklists.
