Cannabinoid Medicine Observational Study (CMOS): Observation of cannabinoid prescribing and dosage patterns in Australian clinical practice

Participants of this study will be receiving prescribed medicinal cannabis product/s via their treating clinician, as per standard of care. Enrolment into the study requires their clinician to consent participants and provide relevant medical history information, prescription information and updates and regular adverse event reporting throughout the study duration (12 months observation per participant). Participants will be asked to complete a total of 14 questionnaires at set time points throughout the study. The study progress questionnaire including additional validated measures of health-related quality of life, medication adherence and patient reported change will be completed at enrolment, and months 1, 3, 6, 9 and 12 post-enrolment or until the participant ceases medicinal cannabis treatment (if prior to 12 months post-enrolment). A short-form questionnaire focused on side effect reporting, current dose and changes to other concomitant medications will be completed at months 2, 4, 5, 7, 8, 10 and 11 post-enrolment or until the participant ceases medicinal cannabis treatment (if prior to 12 months post-enrolment). It is anticipated that each questionnaire will take between 5-30 minutes to complete, requiring a total of 30 minutes maximum participation each month for the 12 months of the study. Clinicians will be asked to complete the baseline enrolment form (10 minutes to complete) for each patient at study enrolment as well as adverse event monitoring questionnaires, each taking 5-10 minutes to complete every 3 months for the period that they have patients enrolled in the study.
