I discovered accidentially that if you use Google.com to search for a disease or ailment, a group of more specific searches appear first. These "result refinements" include
- Causes/Risk factors
- For patients
- For health professionals
- From medical authorities
- Medical alternatives
For example, if you look up bell's palsy, you get this.
While there's the risk of hypochondriacs making mischief with this service, I imagine on balance the result will be better patient information and more carefully directed health care for the savvy.
