An Ounce of Evidence is the blog of Ashish K. Jha – physician, health policy researcher, and advocate for the notion that an ounce of data is worth a thousand pounds of opinion.

I am a practicing Internist physician and a health policy researcher at the Harvard School of Public Health.  I practice medicine in a government run health care system for Veterans, am on staff at Brigham and Women’s Hospital, and am an associate professor of medicine at Harvard Medical School.

Our healthcare system is a mess.  While most physicians and nurses in the U.S. are dedicated, hard-working professionals committed to their patients, the system in which they practice fails them and their patients on a daily basis.  While there is no shortage of opinion on how to fix our system, our research groups tries to bring empirical evidence to the debate.

The blog is my effort to bring data to the discussions about health policy issues — what works, what doesn’t, and why.  But not being without my own biases, this blog will also be a forum for my own interpretations of the data.

Finally, from time to time, we will have guest bloggers.  My hope is that the blog can also become a forum for debate, discussion, and spirited but ultimately respectful airing of the issues involved in fixing the healthcare system.
