Description of intervention(s) / exposure
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.

Outcomes
Primary outcome [1] 323953 0
The type of medicinal cannabis product/s prescribed (including the formulation, prescribed dosage and underlying medical condition) as collected by study-specific questionnaires.
Timepoint [1] 323953 0
Collected at baseline, and then monthly for a 12 month period post-enrolment.
Primary outcome [2] 324126 0
Number of adverse and serious adverse events experienced that are related to medicinal cannabis treatment, including but not limited to, dry mouth, somnolence and gastrointestinal upset, as measured by study-specific questionnaires. These will be captured by clinicians at clinical examinations and also reported by patients on a monthly basis using the safety reporting questionnaire. The safety reporting questionnaires being used are study specific. The clinician AE reporting questionnaire is based on the TGA recommended guidelines for AE reporting which conform to WHO grading and causality definitions.
Timepoint [2] 324126 0
Patient reported data collected at baseline, and then monthly for a 12 month period post-enrolment.
Clinician reported data collected at 3, 6, 9 and 12 months post-enrolment.
Primary outcome [3] 324127 0
Change to patient-reported concomitant medications (including opioid use) over the observational period using study-specific questionnaires.

Statistical methods / analysis
Data will be analysed using SPSS (v25.0, IBM Analytics). Descriptive statistics will be produced with summary data regarding participant demographics, treatment (cannabis formulation and dosage) and patient-reported outcome assessments. Continuous variables with normal distribution will be presented as means with standard deviation; non-normal distribution will be presented as medians with an interquartile range (IQR). Categorical variables will be presented as counts and per cent of the total.

The study will use t-test for the analysis of the continuous variables with normal distribution, and non-parametric Wilcoxon test used whenever parametric assumptions are not satisfied. Longitudinal outcome data overtime (i.e. changes from baseline) will be analysed using repeated measures analysis (e.g. ANOVAs or ANCOVAs to correct for any confounding variables).

Multivariate logistic regression will be used to analyse factors associated with treatment outcomes and Bonferroni-corrected to adjust for multiple testing.
