Cannabis Use Registry to Improve Overall Understanding of Symptoms (CURIOUS)

The CURIOUS project enhances the ability to seamlessly collect patient-level data on symptoms, cannabis use, real-time response to cannabis consumption, and patient-reported changes in supportive care medications such as opioids and antiemetics. Any patient interested in cannabis use can access the weblink to receive information about the CURIOUS study. An electronic version of the informed consent document will be available for them to review.

Patients interested in participating in the CURIOUS study will sign an electronic consent form on the app that describes how data will be used and stored by the HealthPartners and the Ontracka teams. They will be required to submit their name, email, and date of birth. This will automatically establish an account in the OnTracka platform and provide instruction on how to download and install the OnTracka mobile app. After patients consent to participate, they will receive access to the Ontracka app to track cannabis consumption and symptom responses as well as complete embedded validated questionnaires sent to them through the app at defined intervals; NCI PRO-CTCAE (PRO) (every other week), PROMIS Global (QOL) (every 4 weeks) and medication logs (every 4 weeks) through 12 weeks. After week 12 collection, they will complete all surveys once again in month 6 and month 12.
