This article describes the assessment of physicians' attitudes and practices regarding prescribing syringes to injection drug users (IDUs). A brief, anonymous, self-administered questionnaire was sent to all Infectious Disease and Addiction Medicine specialists in Rhode Island. Of 49 eligible physicians, 39 responded (response rate 80%). Most (95%) indicated that there is a legitimate medical reason for IDUs to obtain sterile syringes. Many (71%) agreed that they would prescribe syringes to prevent disease in IDUs if it were clearly legal to do so. We can conclude that physician syringe prescription to IDUs may be an acceptable supplement to existing HIV prevention strategies.
