The words were tucked deep into the sprawling text of President Obama’s signature health-care overhaul . Under the headline “Protection of Second Amendment Gun Rights” was a brief provision restricting the ability of doctors to gather data about their patients’ gun use — a largely overlooked but significant challenge to a movement in American medicine to treat firearms as a matter of public health.
The language, pushed by the National Rifle Association  in the final weeks of the 2010 debate over health care and discovered only in recent days by some lawmakers and medical groups, is drawing criticism in the wake of this month’s schoolhouse massacre of 20 children and six educators in Newtown, Conn. Some public health advocates, worried that the measure will hinder research and medical care, are calling on the White House to amend the language as it prepares to launch a gun-control initiative in January.
NRA officials say they requested the provision out of concern that insurance companies could use such data to raise premiums on gun owners. The measure’s supporters in the Senate say they did not intend to interfere with the work of doctors or researchers.
But physician groups and researchers see the provision as part of a decades-long strategy by the gun lobby to choke off federal support for studies of firearms violence.
