Leading medical professional associations share an interest in advancing the science and improving clinical practice in their fields. DAP identifies and facilitates opportunities for public-private partnerships that are appropriate and transparent, and that evolve from an unmet patient need. These collaborations can take different forms. Clinical and outcome studies result in publications. Peer-to-peer dialogue occurs through meetings or conferences. Educational initiatives targeted to clinicians and patients can take the form of printed or web-friendly enduring materials.
