An evaluation of internet use by neurosurgery patients prior to lumbar disc surgery and of information available on internet.

OBJECTIVE: The aim of this study was to evaluate the Internet use of a group of lumbar disc surgery candidates in order to determine the rate of Internet search by the patients on their disorders and more importantly the reliability of the accessed websites.

PATIENTS AND METHODS: Fifty patients who were scheduled for lumbar disc surgery were divided into 2 groups, namely patients who accepted the surgery at the first offer and those who wanted to think over. Educational level information was obtained and patients were asked whether they had searched their disorder and offered surgery on the Internet. Then, a questionnaire was administered and the reliability of the websites was evaluated. Correction: The first 30 websites on the first 3 pages of Google® search engine, the most commonly used search engine in Turkey, were evaluated with the DISCERN® instrument.

RESULTS: Of 50 patients, 33 (66%) had conducted a search for the surgery on the Internet. All university graduates, 88.2% of high school graduates, and 18.7% of primary-secondary school graduates had conducted an Internet search. The quality and reliability of the information was high (4.5 points) for 2 (7.1%) websites, moderate (2.3 points) for 6 websites (21.4%) and poor (1 point) for 20 websites (71.4%) as scored with the DISCERN® instrument. The mean DISCERN® score of was 1.1 for websites of health-related institutions or healthcare news, 2.75 for personal websites of physicians and 2.5 for personal websites of non-physicians. The mean DISCERN® score of all websites was 1.5.

CONCLUSION: Most of the patients undergoing lumbar disc surgery at our clinic had searched information about the surgical procedure on the Internet. We found that 92.9% of the websites evaluated with the DISCERN® instrument had inadequate information, suggesting low-level reliability.
