Attached here an important survey published several days ago on New England Journal Of Medicine.
I will not summerize the article and let you enjoy reading it by yourself.
Although, I want to quote one sentence:
"Financial barriers were viewed as having the greatest effect on decisions about the adoption of electronic health records".
The above sentence is related to the fact that only minority of the American physician adopted already an EHR platform at their outpatient clinic.
I quoted this sentence because this barrier is perhaps also another opportunity and challenge for the Health 2.0 sector.
Creation of an interactive web based EHR will be probably one of the subcategories in the Medical/Health 2.0 world.
