Assessment of the Effectiveness of Updated Educational Materials on Prescribers' Knowledge and Behavior With Respect to Risks Associated With INSTANYL® Off-Label Use

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of the Instanyl study is to learn how much doctors know and understand about Instanyl® before and after they receive updated educational information, including the risks of its unapproved use. In this study, the doctors will complete two surveys: one three months before they receive the updated educational information, and one about six months after they receive this information. They will answer questions about their prescribing behavior plus their knowledge of Instanyl® including any risks.
