The aim of the study was to ascertain the degree of orthopaedic patients using the internet as a source for information. 450 consecutive patients attending the outpatient department for the first time filled out an anonymous questionnaire. The questions included clinical and socio-demographic data, the availability/access of computers and also the use/interpretation of medical information available on the www.
402 questionnaires were completed. 54 % of these patients had access to the internet. Of the remaining patients without internet access, 19 % planned to install it within the near future. Of the patients who had internet access 68% used it regularly with regard to queries concerning their health and well-being. 38 % had consulted the internet about their specific orthopaedic ailment prior to seeking advice in the clinic. 72% of the patients using www were below 40 years. The use of the www over the age of 40 years was only 49%. 86 % considered the information obtained over the www as helpful or very helpful. 85 % would recommend other patients to use the internet for information concerning their orthopaedic complaint. 65 % of all patients objected to an orthopaedic on-line consultation via internet.
The use of the www is particularly higher in younger, well-educated male patients. More and more patients are willing to undergo internet-based consultation. The increased use of medical web sites by patients raises important issues regarding the need for quality control, and does impact significantly upon the surgeon-patient relationship. The development of academic-based websites should be encouraged, as these offer the most useful information.
