An audit of patients' understanding of routine preoperative investigations

An audit of 100 patients' understanding of preoperative investigations was undertaken at a preoperative assessment unit. Results showed that most patients had a vague understanding of the investigations they would undergo, and that they identified doctors as the main source of information. All health professionals should take responsibility for ensuring that patients have the information they require before surgery. Written information should be provided to patients who request more detailed information about preoperative investigations.
