Profile of drug information centers in the United States.

Better than two-thirds of the DICs polled responded to the questionnaire, which represents a significant and representative profile of drug information services. The information from this survey was intended to compliment previous surveys and published works on DICs. For administrative purposes this collective profile of DICs provided useful information to anticipate and establish the location, staffing pattern, and service functions for a new drug information center. Future surveys should focus upon not only descriptive parameters of DICs, but also should allow and encourage subjective responses that would compare not only "how things are" but also "how things should be".
