PATIENT RECALL OF CONSENT FOR TOTAL HIP ARTHROPLASTY



Abstract

We hypothesise that patients are unable to recall much of the information imparted during the informed consent procedure. This may have important medico-legal consequences and increase patient anxiety. Receiving the information in a written format may improve patient recall. There have been no previous studies testing recall or information sheets for British orthopaedic patients.

We performed a randomised controlled trial of consent for total hip arthroplasty, with one group of patients receiving a written information sheet with explanation as necessary, and the control group receiving the same information verbally. The consent was obtained at a pre-operative assessment clinic approximately three weeks before admission. On admission, a questionnaire was filled in both groups of patients to assess recall.

There were no significant differences between the two groups with regard to type of arthroplasty (revision or primary), age, or days from consent to admission.

The group receiving written information performed better in the recall questionnaire. This group were pleased to have received the information sheet, there were no negative comments about the sheet. In the group who received verbal information, most expressed a desire to receive a written information sheet. One patient stated that she would rather know nothing about the operation and would have refused a sheet. We conclude that patient information sheets are an acceptable and appropriate method of imparting the necessary information for informed consent for total hip arthroplasty, and are more effective than standard verbal informed consent.

Medico-legally, the sheet could be a permanent record of what was discussed. This should prevent disputes and claims due to poor recall of the consent procedure.
