Evidence reports typically tackle several specific questions about topics within such broad areas as adult health, child and adolescent health, maternal health, geriatrics, rehabilitation, dental health, mental health and substance abuse, alternative care, and preventive care. Public- and private-sector organizations nominate topics for evidence reports, and content experts help formulate the questions addressed in the reports. The EPCs compile the report within several months. Drafts are peer reviewed by content experts, representatives of relevant specialty or federal agencies, and AHRQ scientific staff. Revised reports are released on the AHRQ Web site, and parts of the reports deemed most important are often adapted for publication as journal articles.
