Filling a void: thyroid cancer surgery information on the internet.

Overview
abstract
BACKGROUND: Thyroid cancer incidence is increasing, making it an important public health issue. Many patients use the Internet for health-related decisions. Our purposes were to measure the quality of thyroid cancer surgery information on the Internet, and to identify quality predictors. METHODS: The 50 most popular thyroid cancer websites from Google, Yahoo, and MSN were identified. A novel 55-point instrument based on current clinical practice guidelines was designed and used by a Delphi panel of 5 "blinded" endocrine surgeons to assess website information. Each website was independently evaluated by two surgeons. Quality was related to website demographic data using the Student's t-test, chi-square, and ANOVA analyses. RESULTS: Inter-rater reliability for quality scores was excellent (kappa = 0.81). Mean (% of overall quality) score was 21 (38%), and mean score for surgical content was low at 3.5 (29%). Only 50% of sites discussed indications for surgery; 8% length of surgery/anesthesia; 42% the role of lymphadenectomy; 44% recurrent laryngeal nerve injury/hoarseness and 42% hypoparathyroidism as potential complications; 16% recovery; and 20% recommendations for choosing a thyroid surgeon. Only 38% were updated within 2 years. On univariate analysis, no significant associations were found between surgical quality score and website country of origin, currency, sponsorship, authorship, oversight, or references. CONCLUSIONS: Thyroid cancer surgery websites on the Internet are incomplete and outdated. No predictors of quality were identified. Significant improvement is needed in regulating information about thyroid cancer surgery on the Internet, and surgeons may contribute to this effort.
