title: Ancillary studies in clinical trials.
abstract: BACKGROUND
  Randomized clinical trials offer unique opportunities for testing questions of relevance to nursing through the mechanism of ancillary studies.
  
  
  METHODS
  A review of the strategies to prepare and negotiate an ancillary study through a randomized clinical trial structure is offered.
  
  
  RESULTS
  Several steps are required that are unique to the ancillary studies arena. These steps involve (a) accessing the main trial; (b) obtaining approval; (c) funding; and (d) publication. There are hurdles and strategies to address them.
  
  
  CONCLUSIONS
  Collaboration and compromise are the keys to success in the conduct of an ancillary study of scientific merit. The cost-effectiveness, excellent collaboration, and the opportunity to further develop one's research skills and research program in a highly scientific interdisciplinary environment are well worth the effort.
