Abstract
The purpose of the study was to determine the percentage of knowledge retained immediately following an outpatient consultation for total hip and knee joint arthroplasty, and whether any improvement in that knowledge occurred after reading an information leaflet about the operation. Patients who were placed on the waiting list for joint replacement surgery, were verbally given information during the consultation about basic operative details, post-operative programme, and potential complications. A questionnaire was completed asking them to recall these details. Information leaflets were then given to them to read. 6 weeks later they were again contacted and asked the same questions.
Immediately following a consultation, patients recall only a small percentage of information. In particular, retention of post-operative recovery time frames (51–63%), and possible operative complications (0–61 %). Despite an information booklet, their level of knowledge deteriorates from the initial consultation. Verbal and written information supplied to a patient, may be understood, but it is easily and quickly forgotten. In an increasingly medico-legal environment it is essential to gain an informed consent from a patient when performing interventions. The provision of an information booklet may provide nothing more than proof for the surgeon of information provision to the patient.
