Patient knowledge of operative care.

To investigate knowledge of perioperative events, a questionnaire was administered to 111 elective surgical patients. Six topics were covered: the operation, the anaesthetic, time spent in the operating theatre, amount of post-operative pain, duration of hospital admission and time required to return to normal fitness. Apart from evaluating information-sources for each topic, the questionnaire assessed degree of knowledge and satisfaction with this information, and the relationship of these to anxiety. More than 30% of the patients responded that they had received no information about anaesthesia, time in theatre, return to fitness or pain. For each topic more than 40% desired further information. Nursing staff provided most information, although for the anaesthetic, time in theatre, return to fitness and pain, more than 60% of patients responded that nobody had provided explanation. There was no correlation between knowledge relating to the topics per se and anxiety, but there was a significant correlation between satisfaction with information and anxiety. This survey shows a considerable need for improved information provision, especially for patients in whom anxiety is associated with a desire for further explanation of operative care.
