Attitudes of primary care physicians and specialists about cancer clinical trials: a survey of Texas physicians.

A one-page questionnaire assessing physicians' prior involvement in and attitudes about clinical trials was distributed to primary care physicians (PCPs) and specialists practicing in Texas. The survey form was completed and returned by 57 PCPs and 80 specialists. The two physician groups agreed strongly about the value of what can be learned in clinical trials, and agreed that the greatest barriers to participation were paperwork requirements, time constraints, and concern for patient welfare.
