The Agency for Healthcare Research and Quality (AHRQ) (formerly known as the Agency for Health Care Policy and Research) is one of 12 agencies within the United States Department of Health and Human Services (HHS). The agency originally began as the Agency for Health Care Policy and Research and was tasked with producing guidelines. However, it became controversial when it produced several guidelines which would reduce lucrative medical drugs and procedures. This included concern from ophthalmologists on a cataract guideline and concern by the pharmaceutical industry over a reduction in the use of new high-margin drugs. When the agency produced a guideline which concluded that back pain surgery was unnecessary and potentially harmful, a lobbying campaign aided by Congressmen whose backs had been operated on changed the name of the agency and "wound down" the guidelines program.
