Update on the status of 89 drug information centers in the United States.

PURPOSE Previously identified U.S. drug information centers (DICs) were surveyed to determine whether they were still in existence and whether changes had occurred in the DICs since 2003. METHODS Eighty-nine DICs identified in a 2003 survey were surveyed in April 2008. For DICs still in existence, questions were designed to determine whether there were changes in the mission, time spent on activities, staffing, and drug information questions (number, complexity, and time required to answer) compared with five years earlier. Respondents' projected need for their DIC over the next five years was also surveyed. RESULTS Seventy-five (84%) of the 89 DICs were still active. The most notable changes in activities were increases in time spent on educating health-professions students (53%), supporting the institution's medication safety program (44%), and providing information-systems support (36%). The majority of respondents (73%) reported no change in the number of employed drug information personnel. The percentages of DICs reporting an increase, decrease, and no change in the number of drug information requests received were 29%, 42%, and 29%, respectively. Seventy percent reported an increase in the number of complex questions, while 53% reported an increase in the time required to answer each question. Ninety-seven percent of respondents projected no change or an increase in the need for their DIC over the next five years. CONCLUSION Eighty-four percent of the previously identified DICs were still in existence. The most notable changes in these DICs were increases in the number of DICs focusing on educating health-professions students, the complexity of drug information questions, and the amount of time required to answer each request.
