Background: Constant assessment of the quality of health information on the Internet is an absolute necessity as peer review is often lacking in this media. Objective: To develop a simple and easy French Code of Ethics, which will enable medical students to judge quality of health information in teaching material available on the Internet. Design: Three medical informaticians selected ten criteria from previously established codes of ethics from Europe and the USA. This instrument was tested on a sample of 30 health Internet teaching resources. Results: For the panel of experts, chance corrected inter-observer agreement (kappa) for quality rating ranged from k=−0.19 and k=0.33, demonstrating poor agreement among the raters. Conclusion: If negative results of this preliminary study are confirmed by further research, this finding may detrimentally affect projects in Europe to accredit or certify Internet health resources.
