Assessing the adequacy of procedure-specific consent forms in orthopaedic surgery against current methods of operative consent

INTRODUCTION This is an audit of patient understanding following their consent for orthopaedic procedures and uses information on new Orthoconsent forms endorsed by the British Orthopaedic Association as the set standard. The objectives were to: (i) assess whether patients' understanding of knee arthroscopy (KA) and total knee replacement (TKR) at the point of confirming their consent reaches the set standard; and (ii) to ascertain whether issuing procedure-specific Orthoconsent forms to patients can improve this understanding. SUBJECTS AND METHODS This was a prospective audit using questionnaires consisting of 26 (for KA) or 35 (for TKR) questions based on the appropriate Orthoconsent form in a department of orthopaedic surgery within a UK hospital. Participants were 100 patients undergoing KA and 60 patients undergoing TKR between February and July 2008. Participants were identified from sequential operating lists and all had capacity to give consent. During the first audit cycle, consent was discussed with the patient and documented on standard yellow NHS Trust approved generic consent forms. During the second audit cycle, patients were additionally supplied with the appropriate procedure-specific consent form downloaded from www.orthoconsent.com which they were required to read at home and sign on the morning of surgery. RESULTS Knee arthroscopy patients consented with only the standard yellow forms scored an average of 56.7%, rising to 80.5% with use of Orthoconsent forms. Similarly, total knee replacement patients' averages rose from 57.6% to 81.6%. CONCLUSIONS Providing patients with an Orthoconsent form significantly improves knowledge of their planned procedure as well as constituting a more robust means of information provision and consent documentation.
