Radiology and the internet: a systematic review of patient information resources.
OBJECTIVE
To determine whether the internet is a useful resource for patients seeking information on radiological procedures.


METHODS
A systematic search of the world wide web was performed by means of four general search engines (AltaVista, Yahoo!, Infoseek and Excite). Twenty-eight suitable patient-directed websites on arteriography were identified for analysis. The value of this material was measured by establishing inclusion or exclusion of a number of factors relating to the procedure. Readability of the materials was evaluated using the Flesch reading ease score.


RESULTS
Advice on preparation was included in 21 (75%) sites. Contraindications were found in 16 (57%) sites, risks in 6 (21%) and aftercare in 25 (89%). Result availability was discussed in 15 (54%) sites, with links to other radiology sites in 13 (46%). Visual aids were used in 6 (21%) sites and a contact address found in 27 (96%). Mean Flesch reading ease score was 57, with 46% of sites below the preferred minimum of 60.


CONCLUSIONS
Few sites provide the range of information a patient needs before arriving for a procedure. In addition, the readability of the material on these sites is frequently set at a level incomprehensible to patients with lower levels of literacy.
