Shocked and saddened by last week's shooting at Brigham and Women's Hospital, Dr. Miranda Fielding wrote a blog post that appeared on KevinMD, a popular site that gets 5 million clicks a month: "The Legacy of Dr. Michael Davidson." KevinMD, as founder Dr. Kevin Pho puts it, aims "to share the stories of the many who intersect with our health care system, but are rarely heard from," including practicing physicians. He adds: "The public often doesn't know what it's like to work in our health system. KevinMD.com gives them an unfiltered view of our world."
