The project team developed online courses on controlled drugs and safer medication use for various healthcare professionals. Two courses were created that provided 8 hours of interactive learning each. A new website, www.medicinesNI.com, was launched to allow self-registration and access to the courses. Evaluation found the online courses were as effective as print-based learning and live workshops in improving knowledge, though initial participant feedback rated interactivity and presentation of the online courses lower. Over time, as interactivity increased, online course ratings matched live sessions. The program reached over 2,000 learners at a lower cost than other methods.
